The equipment production line is mainly composed of a body machine and a lug welding unit. The body of the face mask is output by the machine. At the discharge port, the body piece of the face mask is transferred by the conveyor belt structure to the first face mask plate on the front of the ear belt machine. Subsequently, the ear belt of the face mask is fused by the ear belt machine to complete the production of a plane external ear belt face mask.

Strict management of turtle turtles in the spring with high efficiency
In the spring, temperatures will rise and all things will recover. The number and virulent capacity of pathogenic microorganisms will continue to increase. Therefore, strengthening the management of soft-shelled turtle spring is the top priority of the spring work of soft-shelled turtles. First, the quality of water "fishing first to raise water", "broad water to raise the big fish" This same principle applies to turtle breeding, soft-shelled turtles like the net fear of dirty, good water environment is the basic conditions for the steady growth of turtles. 1. Changing the water and discharging sewage: In the case of a relatively stable climate after the spring in the open-air overwintering pool and over-winter overwintering pool, appropriate replacement of part of the bottom water and the addition of some new water will reduce the total amount of waste and harmful bacteria in the culture pond. A certain role. 2. Water disinfection: Aquaculture is one of the main ways to spread diseases. Regular and timely disinfection of water bodies is an effective method to control the occurrence of disease. During the spring, the soft-shelled turtle is of weak constitution and milder drugs such as iodine and bromine should be used. 3. Water quality regulation: The pathogenic bacteria that cause soft-shelled turtle disease are mostly conditional pathogens. Generally, they are not easy to survive under partial alkaline conditions. Therefore, quicklime should be used to adjust the pH of the water body regularly to control the pH value between 7.5 and 8.0. The use of lime should not be too large. Regular use of photosynthetic bacteria, EM bacteria and other microbial agents, on the one hand can inhibit the proliferation of harmful bacteria, on the other hand can break down the waste water, waste, etc. in the water, can effectively purify the water body; In addition, in the new pool ready to spill sprinkling microorganisms Formulations can lock and stabilize water color well. The proper amount of stocking some water hyacinths and other aquatic plants can also effectively purify water bodies. 4. Control of water color: The water color directly reflects the population and state of beneficial algae in the water body. The water color of the turtle pond should be kept in a green state, and the algae balance and the water body will be stable. 5. Fertilizer Aquaculture: In the new pond for stocking, it is necessary to vigorously fertilize algae, create a suitable environment for the soft-shelled turtle, and enable the turtle to adapt quickly to the environment. "Fat Underwater Pond" is the reason. Second, the temperature "No spring on the third sunny day", during the spring is a season of changeable weather, whether it is the precipitation of the open-air pool to raise the temperature or warm water pool temperature rise and ventilation and ventilation of these wintering pool Sewage, all should understand the weather changes, depending on the specific circumstances, should not be a large row of irrigation. Graduation ponds during the beginning of spring should also pay attention to the changes in temperature and water temperature, especially if the water temperature does not exceed 3°C. If the temperature difference is too large, whether it is the original turtle pond, or the soft-shelled turtle, it is very likely to cause severe stress reactions, resulting in a large number of deaths. Third, the nutrient temperature rises, the soft-shelled turtle's vitality increases, activities are frequent, and physical energy consumption also increases. It is advisable to feed in a timely manner and increase the amount of bait appropriately, adding more energy-supplying substances and vitamins and some microbial preparations to the bait. Turtles in open-air ponds should be fed with fish, snails, and animal livers in a timely manner to attract food. When the appetite is strong, the amount of compound feed should be increased, and multivitamins, microbial preparations, or antibiotics should be added. Fourth, the period of disease prevention during the spring is a period of frequent occurrence of turtle disease, mainly colds, skin perforation syndrome, fungal diseases, hemorrhagic diseases, etc., should take the same precautions and treatment, ecological prevention and drug prevention and control of the principle. We strongly recommend the use of microbial preparations in water bodies and feeds, and strive to grow a certain area of ​​aquatic plants in the water and stock a certain number of bonito fishes to purify the water body and to feed effective Chinese herbal medicines. Not only economic but also effective, but also in line with the trends and requirements of pollution-free farming. Fifth, cultivating and nurturing relatives is to provide high quality, adequate feed. The quail animal is an omnivorous animal that mainly consists of animal foods. It mainly feeds on small fish, prawns, clams, animal organs, fly pupae, snail meat, and rat meat. It also eats some plant foods such as vegetables and wheat grains. Feeding amount is generally 15% to 20% of the weight of the intimacy. In order to maintain the freshness of the food and facilitate the control of the feeding situation of the quail, a framed feed table slightly below the surface of the water is set up at the poolside or the feed string is hung into the water on the wire. In order to solve the insufficiency of natural feed, some localities have developed some artificially formulated pellet feeds. The basic formula is similar to that of catfish feed. The main reason is that the protein content of feed should be more than 40% (generally about 60%) to facilitate the development of gonads. Development and egg laying. Especially before spawning in the spring, intensive cultivation should be carried out to enhance the body's constitution and increase the spawning rate. Intensive management in the cultivation of intimacy, removal of residues, pay attention to water quality. If any disease or death is found, remove it in time.
