Description

Technical Field

[0001] This utility model belongs to the field of pet food processing technology, specifically relating to a pet food pelleting device. Background Technology

[0002] With the development of society and economy, pets are playing an increasingly important role in people's lives. The quality and variety of pet food are directly related to the health and quality of life of pets. In the production process of pet food, pelleting is a key step. The purpose of pelleting is to process the mixed raw materials into pellets that are suitable for pets to eat. This not only makes it easier for pets to eat, but also improves the storage stability and appearance of pet food.

[0003] Problems with existing technology:

[0004] In the current pet food pelleting process, two pressure rollers rotate relatively evenly to squeeze the material, so that the material is subjected to continuous and uniform extrusion. This can quickly compress the material into pellets, resulting in high production efficiency. The pellets produced have uniform density, regular shape, and good appearance quality, which can meet high production demands. However, during the high-speed production process of the existing pressure rollers, raw materials with a certain degree of moisture are prone to sticking to the inside of the mold groove, which in turn affects the product quality. Utility Model Content

[0005] The purpose of this invention is to provide a pet food pelleting equipment that can clean the inside of the extrusion tank during production, thereby improving product quality.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A pet food pelletizing device includes a support frame. A pressure roller is rotatably embedded in one side of the support frame, and a support rod is rotatably embedded in the other side of the support frame. A roller pressing barrel is integrally fixedly installed at the rear end of the support rod. A second support rod is embedded in the center of the back of the support rod and inside the roller pressing barrel. The rear end of the second support rod is fixedly installed on one side of the rear end of the support frame. A mold groove is formed through the surface of the roller pressing barrel. A top rod is slidably installed inside each mold groove. A top platform is integrally fixedly installed on the top of each top rod, and a boss is integrally fixedly installed on the bottom of each top rod. A top plate and a top plate are integrally fixedly installed sequentially on the outer surface of the second support rod.

[0008] A material trough is fixedly installed on the top of the support frame. Conveying rollers are embedded and rotated inside the material trough. Gear three is fixedly installed at the rear end of the two conveying rollers and on the back of the material trough. Motor two is fixedly installed on the back of the support frame. Gear four is fixedly installed at the output end of motor two.

[0009] Springs are fitted on the outer surface of the top rod and inside the roller drum, and an adsorption layer is detachably assembled on the top of the top platform.

[0010] A conveyor belt is fixedly installed at the bottom of the support frame, and a slide rail is provided at the bottom of one side of the support frame and at the top of the conveyor belt. A groove plate is slidably arranged inside the slide rail.

[0011] Gear 1 is fixedly installed at the front end of both the pressure roller and the support rod 1, motor 1 is fixedly installed at the front end of the support frame, and gear 2 is fixedly sleeved at the output end of motor 1.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This invention, when producing pet food pellets, involves feeding raw materials close to the inside of a feeding trough. Two opposing rotating conveyor rollers evenly distribute the raw materials on top of the pressure rollers and the roller press barrel, improving the quality of pet food extrusion molding. As the raw materials continue to be extruded, the boss at one end of the ejector rod near the top plate contacts and presses the ejector rod, pushing the extruded food out of the mold cavity. This ensures the pressed food is completely removed, preventing raw materials from adhering to the mold cavity and improving production quality. It also increases the feeding speed and overall production efficiency. As the roller press barrel continues to rotate, the boss at one end of the ejector rod contacts the top plate again, pressing the ejector rod and pushing it out of the mold cavity again. The ejector rod then contacts the release agent inside the mold cavity, which absorbs and coats the inside of the mold cavity through an adsorption layer, preventing raw materials from adhering and further improving production quality.

Detailed Implementation

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figures 1-5 As shown, a pet food pelletizing device includes a support frame 2. A pressure roller 11 is embedded and rotatably arranged on one side of the support frame 2, and a support rod 12 is embedded and rotatably arranged on the other side of the support frame 2. A roller pressing barrel 13 is integrally fixedly installed at the rear end of the support rod 12. A support rod 26 is embedded in the center of the back of the support rod 12 and inside the roller pressing barrel 13. The rear end of the support rod 26 is fixedly installed on one side of the rear end of the support frame 2. A mold groove 15 is opened through the surface of the roller pressing barrel 13. A top rod 19 is slidably arranged inside the mold groove 15. A top platform 20 is integrally fixedly installed on the top of the top rod 19, and a boss 23 is integrally fixedly installed on the bottom of the top rod 19. A top plate 17 and a top plate 28 are integrally fixedly installed on the outer surface of the support rod 26 in sequence.

[0023] See attached document Figure 1 , Figure 3 and Figure 4 Gear 4 is fixedly installed at the front end of the pressure roller 11 and the support rod 12. Motor 6 is fixedly installed at the front end of the support frame 2. Gear 5 is fixedly sleeved at the output end of the motor 6. Conveyor belt 3 is fixedly installed at the bottom of the support frame 2. A slide rail is provided at the bottom of one side of the support frame 2 and at the top of the conveyor belt 3. A groove plate 14 is slidably installed inside the slide rail. Spring 22 is sleeved on the outer surface of the top rod 19 and inside the roller barrel 13. An adsorption layer 21 is detachably assembled on the top of the top platform 20.

[0024] According to the above structure, the motor 6 drives the gear 5 to rotate, which in turn causes the meshing gear 4 to rotate, thereby causing the pressure roller 11 and the roller drum 13 to rotate relative to each other, thus extruding and granulating the raw material. As the motor 6 continues to rotate, the circular boss 23 of the push rod 19 contacts the arc-shaped end of the top plate 17, causing the push rod 19 to push outward of the roller drum 13, thus pushing the extruded pet food out onto the conveyor belt 3. This increases the feeding speed, thereby increasing the overall production speed, and also cleans the inside of the mold groove 15, improving production quality and avoiding affecting the quality of subsequent production. When the roller drum 1... 3. During continuous rotation, the boss 23 is squeezed out again by the arc-shaped section of the top plate 18, causing the ejector rod 19 to be ejected from the mold groove 15. The absorbent layer 21 of the polyester fiber absorbent cotton material on the top of the top plate 20 is inserted into the mold release agent on the top of the groove plate 14, thereby absorbing the mold release agent. When the ejector rod 19 and the boss 23 that were in contact with the top plate 18 are no longer in contact with the top plate 18, the ejector rod 19 retracts into the mold groove 15 again under the action of the spring 22. When the ejector rod 19 retracts, the absorbent layer 21 on the top of the top plate 20 retracts synchronously, wiping the inner wall of the mold groove 15, thereby preventing raw materials from sticking to the mold groove 15 and improving the product production quality.

[0025] See attached document Figure 2 The top of the support frame 2 is fixedly installed with a material trough 1. The material trough 1 is embedded with a rotating conveyor roller 10. The rear end of the two conveyor rollers 10 and the back of the material trough 1 are fixedly installed with gear 3 7. The back of the support frame 2 is fixedly installed with motor 2 9. The output end of motor 2 9 is fixedly installed with gear 4 8.

[0026] According to the above structure, when producing pet food pellets, the raw materials are fed into the feed trough 1. The motor 2 9 drives the gear 4 8 to rotate, which in turn drives the gear 3 7 meshing with it to rotate. This causes the two opposing conveyor rollers 10 to rotate relative to each other, so that the raw materials are evenly spread on the top of the pressure roller 11 and the roller pressing barrel 13, and the mold trough 15 is evenly filled with raw materials, thereby improving the product production quality.

[0027] The working principle of this utility model is as follows: When producing pet food pellets, the raw materials are fed into the feed trough 1. Motor 2 9 drives gear 4 8 to rotate, which in turn drives gear 3 7 meshing with it to rotate, causing the two opposing conveyor rollers 10 to rotate relative to each other. This allows the raw materials to be evenly spread on the top of the pressure roller 11 and the roller pressing barrel 13, and the die groove 15 to be evenly filled with raw materials, improving the product quality. Motor 1 6 drives gear 2 5 to rotate, which in turn drives gear 4 meshing with it to rotate, causing the pressure roller 11 and the roller pressing barrel 13 to rotate relative to each other, thereby extruding and pelletizing the raw materials. As motor 1 6 continues to rotate, the circular boss 23 of one section of the push rod 19 contacts the arc-shaped end of the top plate 17, causing the push rod 19 to push outwards from the roller pressing barrel 13, thus pushing the extruded pet food pellets out and onto the conveyor belt 3. On the one hand, it increases the material feeding speed, thereby increasing the overall production speed. On the other hand, it cleans the inside of the mold groove 15, improving production quality and avoiding affecting the quality of subsequent production. When the roller barrel 13 continues to rotate, the boss 23 is squeezed out again by the arc section of the top plate 18, causing the ejector rod 19 to be ejected from the inside of the mold groove 15. The absorbent layer 21 of the polyester fiber absorbent cotton material on the top of the top plate 20 is inserted into the mold release agent on the top of the groove plate 14, thereby absorbing the mold release agent. When the ejector rod 19 and the boss 23 that are in contact with the top plate 18 are no longer in contact with the top plate 18, the ejector rod 19 retracts into the inside of the mold groove 15 again under the action of the spring 22. When the ejector rod 19 retracts, the absorbent layer 21 on the top of the top plate 20 retracts synchronously, wiping the inner wall of the mold groove 15, thereby avoiding the adhesion of raw materials in the mold groove 15 and improving the product production quality.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
