Key words: tablet press, diversified, custom-made, profiled die rotary tablet press (hereinafter referred to as tablet press), more and more customized orders, customers' diversified needs are increasingly obvious, more tablet products Variety, and this potential demand is vast, far beyond the scope of the pharmaceutical equipment industry, and applied in all walks of life, it needs personalized tablet equipment to turn it into reality, which indicates pressure The tablet market will develop in a diversified direction. Customized, small-volume, and diversified production will be an important choice for tablet equipment manufacturers. Take the company as an example. In the tablet presses sold in 2008, the number of customized products accounted for 30% of the total sales, sales accounted for 50% of the total sales, and the profits generated accounted for 70% of the total profit. . Through the analysis of the diversification requirements of the tablet press users, the succinct view of the tablet press market will be diversified, introducing different types of tablet presses, press dies and their characteristics, and analyzing the different requirements of their use. I hope that the use of tablet press users will be helpful, and it will be beneficial to the selection and purchase of tablet equipment buyers.
1. Diversification requirements for tablet products 1.1 Diversification of tablets and methods of compression For the manufacturers of tablets, the products are no longer a single round tablet, but with a variety of diversification Claim,
1.1.1 From the shape, there are a variety of requirements, such as ring, square, trapezoid, ellipse, triangle, sphere, petal shape, deep concave, shallow concave and so on. In order to achieve the suppression of these tablet products, the die needs to be customized according to the user's tablet products, most of which are non-standard die. In the habit, we will suppress the die of non-circular tablets such as square, trapezoid, triangle, and petal. For the profiled die, the upper punch of this type of die needs to be configured with an orientation key, and the upper punch hole of the turntable needs to process the keyway to cooperate with the punch to complete the pressing of the tablet.
1.1.2 From the color points, there are monochrome, two-color film and so on. The monochromatic film is pressed with a material. The two-color film requires two materials (that is, the two materials are pressed into one tablet, but the layers and colors are distinct), and to achieve the pressing of the two-color film, the tablet press is required. The undercut rail system is modified to achieve two fillings and one sheet at a time. Among them, if a special film taking device is added, the content of one of the materials can be measured to control the ratio of the two materials of the tablet.
1.1.3 is divided into words with or without words, with Chinese characters, letters, graphics, and so on. The suppression of the tablet is also made according to the sample of the user's tablet product, and the corresponding Chinese characters or graphics are processed on the die to realize the tablet pressing.
1.1.4 Divided from the size of the shape, there are standard shapes and sizes, and there are oversized specifications. For large-sized tablet products, it is necessary to order large-size die, and to modify the structure of the tablet press, mainly to transform the filling adjustment system, pressure regulation system, guide rail system and turntable.
1.2 Diversification of the structure of the tablet press The requirements for the diversification of the structure in the user's customized order are mainly reflected in the following aspects:
1.2.1 On the way of filming, there is a requirement for single-sided filming. If there is a requirement for double-sided filming, there is a requirement that both one-sided film and two-sided film can be produced. This requires designing and transforming the sheet structure of the tablet press to achieve different requirements.
1.2.2 In terms of protection, if there is a requirement for a break protection structure, there is an automatic power-off protection when the tablet door is required to be opened. The breakage protection structure means that when the ram suddenly breaks under the accidental condition, the break protection system reacts quickly, the equipment immediately stops automatically, prevents the occurrence of a safety accident, eliminates the hidden danger in the bud; and automatically cuts off the power when the tablet door is opened. It means that the tablet press can not be operated in the state where the tablet door is opened. When the tablet press is in normal operation, the tablet door will be opened automatically, and the machine will automatically stop quickly. . This requires a dual design modification of the mechanical and electrical parts, and the detection signal is passed to the electrical control system to achieve automatic protection control.
1.2.3 There are special requirements for the structure and material of some parts. For example, some users in the military industry or the automotive industry have explosion-proof requirements for tablet devices: 1) require electrical devices to use explosion-proof type; 2) operating system and host separate, can be operated remotely; 3) tablet door is made of stainless steel It is sturdy and durable, and it is resistant to corrosion. 4) The feeding device is required to be made of glued wood to avoid reaction with materials.
1.2.4 In terms of operation control, most of the tablet press's operating system and host are integrated, while others require the operating system to be independent and can be operated from a distance. According to the user's requirements, the electrical operating system is designed and modified, and the independent electrical cabinet is designed and processed. The operating system and the independent electrical cabinet are connected with the mainframe cable, thus realizing remote operation control.
2. Special requirements of the tablet press structure and the use requirements analysis of the tablet press with special requirements, its structure has its specific location, the use requirements also need to pay attention to, from the following several common models to analyze and introduce.
2.1 The structure and use requirements of the tablet press using the profiled die The tablet pressed by the profiled die has clear positioning requirements for the die during pressing, such as square, trapezoidal, triangular, elliptical, polygonal, etc. shape. The requirement for the structure of the tablet press is mainly that the upper punch hole of the turntable processes the keyway to position the upper punch. The requirement of the punch die is that the upper punch has an orientation key, so that it fits with the upper punch hole of the turntable during installation. Because the lower punch does not leave the middle die hole during the process of pressing, the positioning and matching are clear, and no special processing is needed.
When the tablet is pressed by the special die, the punch has a positioning in the punch hole and cannot be freely rotated, and can only be moved up and down along the upper and lower rails, and the friction of the guide rail and the guide rail are sliding friction, so that It is easy to aggravate wear: one is the wear of the guide rails, and the other is the wear of the turntable. Therefore, during the use process, pay great attention to the lubrication of the punch and the guide rail, and form a daily lubrication and maintenance system; the keys of the punch should also be checked. If the key is loose, the keys and the keyway and the punch and the punch hole will be abnormally worn. In turn, it affects the positioning requirements of the punch for the middle mold, resulting in a "bite punch" phenomenon, which seriously damages the punch and the middle mold and cannot be produced normally.
When installing the profiled die, firstly, the punch and the middle die should be positioned accurately. After the puncher enters the middle die freely, the middle die top wire is fastened to prevent the punch and the middle die from "biting" due to inaccurate positioning. After all the dies are installed, apply the handwheel for a few laps, no abnormalities, and then run the power.
2.2 Two-color tablet press structure and use requirements analysis Two-color tablet press is to press two different materials into one tablet, and the two materials are separated from each other, the color is clear, to achieve the compression of the two-color tablet The structure of the film machine is mainly to design and transform the lower rail to realize two filling and one sheeting. The main situation that occurs during the suppression of the two-color film is:
1) The content of the two materials on the same tablet does not meet the requirements. This is mainly because the filling adjustment system is not adjusted. The content of one material can be adjusted first, and the content of the other material can be adjusted.
2) The two materials pressed out of the tablet have the phenomenon of fragmentation, uneven hardness, one material is hard, and one material is soft. There are two main reasons: one is the material, the density of the two materials, the dry humidity, The uniformity is not adjusted well, and the material is adjusted and then pressed. Second, the pressure of the two materials is not adjusted well. The principle of the two-color film is secondary filling, once in a piece, if the pressure is not adjusted after * filling Then, the hardness of the lower half is hard or soft. After the second filling, the pressure is set for a whole tablet, so the adjustment of the pressure determines the degree of tableting and bonding.
The two-color tablet press generally needs to be equipped with two vacuum cleaners, which can separately absorb the two materials and recycle them. If the user has precise requirements on the composition of the two materials, the tablet press can be provided with a separate piece for the tablet extruded from one of the materials, and the measurement can be accurately measured to determine the content.
2.3 Ring sheet tablet press structure and use requirements analysis As the name suggests, the tablet pressed by the ring press machine is a ring shape, the main structure is on the die, the middle part of the punch is machined with a round hole, and the core rod The groove is machined on the side; the structure of the tablet press is modified by adding a pressure plate to the die hole in the turntable for use with the die to complete the pressing of the ring piece. The installation of the annular die is more troublesome than the installation of a conventional tablet press die, as is the case.
2.4 Explosion-proof requirements Tablet press structure and use requirements Analysis Explosion-proof tablet presses are mainly used in military, automotive and other industries. The pressed tablets are inflammable and explosive products, requiring the structure of the tablet press and the materials used. Adapt to explosion-proof requirements. Taking the rotary sub-high-speed tablet press ZPYGS51 produced by our company as an example, the main motor and feeding motor used are explosion-proof motors, and the electrical cabinets are designed independently. The operating system and the electrical cabinet are displayed together to realize long-distance operation. The pipeline is connected with the main engine in accordance with the explosion-proof requirements; the die adopts the I series, and the turntable has good guiding; the rotary table is equipped with an interrupt protection system; the filling pressure regulating system is equipped with a locking device; the display operating system realizes filling, The display or setting of pressure, preload, production, fault and parameter adjustment, the whole machine design is safe, convenient and humanized.
3. The introduction of the tablet press introduces the series of products of the company, in addition to the general-purpose machine series, on the road of diversified development, we are steadily moving forward, order-order production for the special requirements of users, the following tablet press The classification and comparison analysis of each parameter can lead to some useful conclusions.

1) The tableting force, tableting diameter and tableting thickness of the user-customized tablet press tablet are larger, and the requirements for the tablet shape specification are far greater than that of the ZP die, mainly used in chemical, electronic, food, military , automobiles and other enterprises;
2) User-customized tablet presses have lower yields due to their special requirements;
3) User-customized tablet press has special requirements for explosion-proof, operating system, material and materials;
4) DDY-I type large single punching machine is a kind of machine featuring Zui. It can suppress extra large and various shapes of tablets, pressed annular piece, zui large outer diameter is ø80, and the hole diameter is (1/ 4~1/2) outer diameter, the die is customized according to user requirements, this aspect has the unparalleled advantages of rotary tablet press. The disadvantage is that the working principle is stamping type, the working efficiency is low, and the weight difference of the pressed tablets is large.
4. Summary In the user's customized equipment, in addition to the above description, there are many diverse requirements. According to the different requirements of users, we have innovatively designed and processed the equipment and die to meet the requirements of users. It is bound to bring pressure and challenges to the management of enterprises. It also requires us to adapt to new needs in all aspects of basic management such as technology management, production management, quality management, and standardized management, and improve the resilience of enterprises. It should be changed.
Tablet manufacturing companies are no longer just pharmaceutical companies, but are increasingly being widely used in food, chemical, electronics, military, automotive and other enterprises, and have a tendency to develop in depth. The users facing pharmaceutical equipment companies are no longer It is only limited to pharmaceutical factories. Only by fully tapping the market and meeting the requirements of different industries and different users can we make great progress.
