[0002] Pet food is food specifically designed for pets. It is usually customized according to the pet's breed, age, and health condition. The main purpose of pet food is to meet the pet's nutritional needs and provide a balanced nutritional composition, while also taking into account factors such as taste, digestibility, and hygiene. There are many types of pet food, including dry food, wet food, treats, and supplements. When choosing pet food, owners need to understand their pet's eating habits, taste preferences, and physical condition in order to select the appropriate food for them.
[0003] Pet food comes in many varieties, and the processing of pet food results in particles of varying sizes. Therefore, a raw material screening device for pet food processing is needed to screen these materials. Existing such devices typically use vibration to pass the raw materials through a screen. However, this process can cause raw materials to get stuck in the gaps of the screen, preventing them from being sieved through vibration. It also makes subsequent cleaning of the screening equipment difficult. Furthermore, due to the light weight of the raw materials, they may splatter out of the screening device during vibration, thus affecting the device's screening efficiency. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 As shown, a raw material screening device for pet food processing includes a cabinet 1, which protects the screening hopper 5. Two doors 2 are provided on one side of the cabinet 1 for sealing. An outer shell 3 is provided inside the cabinet 1 to protect the vibrating mechanism 4. The vibrating mechanism 4, located inside the outer shell 3, is used to screen pet food raw materials and drives the screening hopper 5 to vibrate. The 1 is equipped with a sieve hopper 5, which facilitates the screening of pet food ingredients. The inner wall of the sieve hopper 5 is fixed with a limit block 6, which facilitates the positioning of the screen 7. The top of the limit block 6 is slidably connected to the screen 7, which facilitates the screening of pet food ingredients. The sieve hopper 5 is equipped with a first discharge port 8 and a second discharge port 9 on one side, which facilitates the discharge of pet food ingredients separately.
[0023] The vibrating mechanism 4 includes a motor 41 disposed on the inner wall of the outer casing 3. By disposing of the motor 41, it is easy to drive the crank shaft 42 to rotate. The output end of the motor 41 is fixed to the crank shaft 42. By disposing of the crank shaft 42, it is easy to drive the connecting block 43 to move up and down. The outer side of the crank shaft 42 is rotatably connected to the vertically disposed connecting block 43. By disposing of the connecting block 43, it is easy to connect the guide rod 44 to the crank shaft 42, and at the same time, it is easy to drive the guide rod 44 to move up and down. The inner wall of the connecting block 43 is rotatably connected to the vertically disposed guide rod 44. By disposing of the guide rod 44, it is easy to move up and down along the inner wall of the sleeve 45. The bottom of the screen hopper 5 is fixed to the sleeve 45, and the inner wall of the sleeve 45 is slidably connected to the outer side of the guide rod 44. By disposing of the sleeve 45, it is easy to limit the guide rod 44.
[0024] The top of the cabinet 1 is connected to a vertically arranged feed hopper 10, which facilitates the pouring of pet food ingredients into the sieve hopper 5. A first limiting groove 11 is provided on one side of the cabinet 1 to limit the first discharge port 8. A second limiting groove 12 is provided on the top of the outer shell 3 to limit the guide rod 44.

By setting the support seat 18, the crank shaft 42 can be easily supported.
[0026] Working principle: In use, pet food raw materials are first poured into the sieve hopper 5 through the feed hopper 10. Then, the motor 41 is started, which drives the crank shaft 42 to rotate. The crank shaft 42 drives the connecting block 43 to move up and down, and the connecting block 43 drives the guide rod 44 to move up and down. The guide rod 44 moves up and down along the inner wall of the sleeve 45, thereby causing the sieve hopper 5 to vibrate. Then, the sieve hopper 5, the limiting block 6, the screen 7, the first discharge port 8 and the second discharge port 9 work together to screen the pet food raw materials and discharge them separately. During the operation, the sieve hopper 5 is supported by the first fixing block 13, the first spring 14 and the second fixing block 15. The sieve hopper 5 is damped by the second spring 16 and the damper 17. At the same time, the damper 17 establishes a resistance between the vibration source and the load, thereby reducing the amplitude and the speed of vibration transmission, improving the practicality of the main body.
