Description

Technical Field

[0001] This invention relates to the technical field of pet food processing, and more specifically to a crushing and screening device for pet food processing. Background Technology

[0002] With the booming development of the pet breeding industry, the market demand for pet food continues to rise, and consumers are placing higher demands on the quality, nutritional balance, and palatability of pet food. In the pet food processing technology, the crushing and screening of raw materials is a crucial preliminary step, and its processing effect directly affects the efficiency of subsequent mixing, pelleting, and other processes, as well as the uniformity, digestibility, and taste of the final pet food product.

[0003] In the screening process, the screening mechanism of existing equipment generally suffers from the defect of a single screening method. Most of them can only achieve vibration screening in one direction. The movement trajectory of the screening box is fixed and simple, which leads to uneven distribution of raw materials on the screen surface. Some fine particles are easily trapped by coarse particles and cannot pass through the screen holes quickly. This not only prolongs the screening time and reduces production efficiency, but also easily leads to the problem of incomplete screening. Summary of the Invention

[0004] The purpose of this invention is to provide a crushing and screening device for pet food processing, so as to overcome the above-mentioned defects in the prior art.

[0005] A crushing and screening device for pet food processing includes a box, a crushing mechanism and a screening mechanism. The top of the box is provided with a feeding hopper, and the side of the box is hinged with a door. The crushing mechanism is located in the feed hopper and is used to crush the pet food raw materials; The screening mechanism is located in the box and is used to screen the crushed pet food raw materials.

[0006] Preferably, the crushing mechanism includes a crushing roller and a crushing motor. Two crushing rollers are provided and rotatably connected in the feed hopper. Each crushing roller has a gear 1 at its outer end, and the two gear 1s mesh with each other. The crushing motor is installed on the top of the housing and a gear 2 is installed on its output shaft. The gear 2 meshes with one of the gear 1s.

[0007] Preferably, the screening mechanism includes a movable frame, a screening box, a drive motor, a top plate, and a collection box. The two sides of the movable frame are slidably connected to the inner wall of the box via slide rails. A fixed frame is connected to the movable frame via fixing bolts. The screening box is connected to the fixed frame via springs. Fixed plates connected to the inner wall of the box are symmetrically arranged on the lower two sides of the movable frame. A movable plate is connected to the bottom of the movable frame via a connecting plate. The movable plate is slidably connected to a support frame on the inner wall of the box. A sector gear is provided on the top plate that meshes with a rack on the movable plate. The sector gear is hinged to the fixed plate via a pin. A drive motor is installed on each fixed plate. A drive plate is provided on the output shaft of the drive motor. A rod is inserted into a drive groove on the top plate on the drive plate. The collection box is located below the fixed plate.

[0008] Preferably, the fixing bolts are provided in two symmetrical threaded connections on both sides of the movable frame.

[0009] Preferably, the springs are provided in four locations, each located at one of the four corners of the fixed frame.

[0010] Preferably, the fixing plate has an overall "L" shaped structure.

[0011] Preferably, each movable plate is slidably connected to two support frames on the inner wall of the box.

[0012] Preferably, a rubber pad is provided at the end of the top plate that contacts the bottom of the screening box.

[0013] Preferably, the door is connected to the box body via several industrial fasteners.

[0014] The beneficial effects achieved by this invention are as follows: This application uses a crushing mechanism to crush pet food raw materials. The crushed raw materials enter the screening box of the screening mechanism. When the drive motor drives the drive plate to rotate, the top plate swings back and forth through the cooperation of the insert rod and the drive groove of the top plate. On the one hand, the top plate periodically lifts the screening box to achieve up and down vibration; on the other hand, the meshing of the sector gear on the top plate and the rack of the moving plate drives the moving frame and screening box to move horizontally back and forth along the slide rail. This multi-dimensional screening method makes the raw materials in the screening box vibrate continuously, effectively avoiding the accumulation of raw materials, ensuring that fine particles pass through the screen holes quickly, and coarse particles are accurately intercepted, significantly improving screening efficiency.

[0026] like Figure 1-8 As shown, the present invention provides a crushing and screening device for pet food processing, including a box body 1, a crushing mechanism 3 and a screening mechanism 4. The top of the box body 1 is provided with a feeding hopper 2, and the side of the box body 1 is hinged with a box door 11. The box door 11 is connected to the box body 1 by several industrial buckles 12 to facilitate opening the box door 11. In addition, the crushing mechanism 3 is located in the feed hopper 2 and is used to crush pet food raw materials. The crushing mechanism 3 includes crushing rollers 31 and crushing motor 33. There are two crushing rollers 31 and they are rotatably connected in the feed hopper 2. Each crushing roller 31 has a gear 32 at its outer end. The two gears 32 mesh with each other. The crushing motor 33 is installed on the top of the housing 1 and a gear 34 is installed on its output shaft. The gear 34 meshes with one of the gears 32. The two rotating crushing rollers 31 form a shearing and squeezing action, which can efficiently and uniformly crush pet food raw materials.

[0027] In addition, the screening mechanism 4 is located in the box 1 and is used to screen the crushed pet food raw materials. The screening mechanism 4 includes a moving frame 41, a screening box 44, a drive motor 48, a top plate 47 and a collection box. The two sides of the moving frame 41 are slidably connected to the inner wall of the box 1 through slide rails 411. The moving frame 41 is connected to a fixed frame 43 by fixing bolts 412. There are two fixing bolts 412, which are symmetrically threaded and connected to the two sides of the moving frame 41. The setting of the two bolts not only ensures the fixing strength, but also makes the operation of installing and disassembling the screening box 44 relatively simple. However, the screening box 44 is connected to the fixed frame 43 by springs 431. There are four springs 431 and they are respectively located at the four corners of the fixed frame 43. The four springs 431 provide uniform elastic support so that the screening box 44 remains balanced when vibrating and avoids tilting or twisting. In addition, the lower sides of the movable frame 41 are symmetrically provided with "L"-shaped fixed plates 45 that are connected to the inner wall of the box 1. The bottom of the movable frame 41 is connected to a movable plate 461 through a connecting plate 46. Each movable plate 461 is slidably connected to two support frames 463 on the inner wall of the box 1 to prevent shaking and improve the accuracy and reliability of the movement. In addition, a rubber pad 472 is provided at the end of the top plate 47 that contacts the bottom of the screening box 44, which can buffer the impact of the top plate 47 on the bottom of the screening box 44 and extend the service life of the top plate 47 and the screening box 44. The top plate 47 is provided with a sector gear 473 that meshes with the rack 462 on the moving plate 461. The sector gear 473 is hinged to the fixed plate 45 through a pin. Each fixed plate 45 is equipped with a drive motor 48. The output shaft of the drive motor 48 is provided with a drive plate 49. The drive plate 49 is provided with a rod 491 that is inserted into the drive groove 471 on the top plate 47. The collection box is located below the fixed plate 45. The screening box 44 can vibrate up and down and move left and right at the same time, thereby screening the crushed pet food raw materials in the screening box 44.

[0028] Detailed implementation methods and principles: The pet food raw materials to be processed are put into the feed hopper 2 at the top of the box 1. The crushing motor 33 and the drive motor 48 are started. The output shaft of the crushing motor 33 drives the gear 2 34 at its end to rotate. The gear 2 34 drives the gear 1 32 and the crushing roller 31 to rotate. The pet food raw materials are crushed by the rotating crushing roller 31, and the raw materials with large blocks or particles are crushed into smaller particles. The crushed raw material particles fall into the screening box 44 inside the box 1 through the opening below the feed hopper 2. After the crushed raw material enters the screening box 44, the output shaft of the drive motor 48 drives the drive plate 49 at its end to rotate. The insertion rod 491 on the drive plate 49 is inserted into the drive groove 471 of the top plate 47. As the drive plate 49 rotates, the insertion rod 491 will make a circular motion in the drive groove 471, thereby pushing the top plate 47 to swing back and forth about the pin hinged to the fixed plate 45. During the swinging process, the end of the top plate 47 that contacts the bottom of the screening box 44 will periodically lift up or lower down. The screening box 44 vibrates up and down. At the same time, the sector gear 473 on the top plate 47 meshes with the rack 462 on the moving plate 461. The swing of the top plate 47 will drive the sector gear 473 to rotate, which in turn drives the moving plate 461 to move horizontally back and forth along the support frame 463 on the inner wall of the box 1 through the rack 462. The moving plate 461 drives the moving frame 41 to slide back and forth on the inner wall of the box 1 through the connecting plate 46, thereby performing left and right screening in the screening box 44. Coarse particles of pet food raw materials with a particle size larger than the sieve aperture of the screening box 44 are trapped inside the screening box 44. After processing, the box door 11 is opened by industrial buckle 12, and the fixing frame 43 is removed by disassembling the fixing bolts 412 on both sides of the moving frame 41, so that the coarse particles inside the screening box 44 can be cleaned or subjected to secondary crushing.
