Common embodiment of a support cradle, there are four :( 1) sliding support; (2) rolling bearings; (3) shaking the support; (4) supported by the leaf spring. See the principle of four kinds of the support shown in the embodiment in FIG. The way of support determines the trajectory of the bed surface and thus the selection process. The performance of the various support methods is listed in the table below. Common Shaker Support Mode Performance Table Supporting method Bed surface trajectory Performance and application 1. The sliding bearing straight line Smooth operation, and reliable; easy to wear, but greater resistance. Cloud tin shaker using this support 2. Scroll support straight line The resistance is small, but the roller is prone to wear. Spring shaker uses this support 3. Shaking support Arc The bed surface has a slight up and down vibration, which is beneficial to the loosening of the ore particles. 6-S shaker uses this support 4. Elastic support Arc The structure is simple, the resistance is small, but it cannot support a large pressure, and the application is currently less. Fast shaker using this support The grade adjustment mechanism is used to adjust the lateral slope of the bed surface of the shaker. They are usually installed under the shaker. There are two main types of slope-adjusting institutions in China: (1) Yunxi shaker slope adjustment mechanism. It is made up of plain bearings and wedges. As shown below. The utility model has the advantages of simple structure, low cost, convenient and precise adjustment, and is not easy to wear. YTC shaker and shaker are using this spring slope adjustment means adjusting its slope in the range of 3 ° ~ 8 °, smaller slope adjustment range. [next] (2) 6-S shaker slope adjustment mechanism. This slope adjustment mechanism adjusting mechanism flexible than YTC shaker, light, major slope range (0 ° ~ 10 °), the disadvantage is more complex structure. The 6-S shaker uses this grade adjustment mechanism. Its structure is shown in the figure below.
1. Raw material pulverization: Raw materials are mainly divided into two categories, starch and fat. Starch is mainly various grains. Its pulverization can be achieved by ordinary pulverizers. It only needs to ensure the fineness and clean raw materials during the pulverization process. Hygiene can be. Use a colloid mill to pulverize into separate packs or puree, and the meat only needs to be pulverized into meat puree or powder with a colloid mill, and then added to the grain powder and stirred evenly.

2. Raw material mixing: The mixing equipment has two functions, one is to mix all kinds of raw materials evenly, and the other is to adjust the moisture and humidity. It is generally a vertical rapid mixer: the mixing time is short, the mixing is completed quickly, and the machine is used before the humidity of the raw material changes significantly, which ensures the uniformity and quality of the puffing of the dog food particles. The disadvantage is: the single-cylinder mixing capacity is small, and it needs to be stirred all the time during the production process.
3. Raw material extrusion, puffing and curing molding: The twin-screw extruder extrudes and extrudes under high temperature and high pressure, and produces dog food and cat food particles of different styles and shapes by changing different molds. For different raw material ratios and humidity, it is necessary to adjust the temperature and screw speed of different regions and the feeding speed of the feeder to ensure that the produced dog food particles are of high quality and good appearance.
