DETAILED DESCRIPTION

[0024] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] A grinding device for producing pet food, such as Figure 1-Figure 5As shown, it includes a sorting frame 1, a grinding frame 2, a feeding cylinder 3, a driving motor 4, a grinding block 5, a collecting frame 6, a material guide net 7, a screening mechanism and a feeding mechanism. The top of the sorting frame 1 is connected to the grinding frame 2, and the upper left part of the grinding frame 2 is connected to the feeding cylinder 3, through which feed can be added to the grinding frame 2, the lower part of the grinding frame 2 is provided with an inverted cone-shaped grinding chamber, the upper part of the grinding frame 2 is installed with a driving motor 4, the output shaft of the driving motor 4 is connected with a grinding block 5, and the grinding The lower part of the block 5 is located in the grinding chamber. When the feed passes through the grinding block 5 and the grinding chamber, the feed can be ground by the grinding block 5. The bottom of the sorting frame 1 is slidably connected to a removable collecting frame 6, and the upper part of the sorting frame 1 is slidably connected to a material guide net 7. The material guide net 7 is inclined with the left side higher and the right side lower. The grinding frame 2 is provided with a screening mechanism for screening the ground pet feed, and the sorting frame 1 is provided with a feeding mechanism for re-feeding the screened feed with a larger particle size for grinding.

[0026] like Figure 2 and Figure 3 As shown, the screening mechanism includes a screening mesh 81, a screening cone 82, a baffle plate 83 and a V-shaped sweeping rod 84. The lower part of the grinding frame 2 is connected to the screening mesh 81. An opening is opened on the left side of the screening mesh 81 for larger-sized feed to slide down. The middle of the screening mesh 81 is connected to the screening cone 82. A baffle plate 83 is connected to the upper left side of the sorting frame 1. The baffle plate 83 is used to block the opening on the screening mesh 81. The top of the baffle plate 83 is inclined with the left side higher and the right side lower. A V-shaped sweeping rod 84 is rotatably connected to the baffle plate 83. The V-shaped sweeping rod 84 is in contact with the screening cone 82 and the top of the screening mesh 81, and the V-shaped sweeping rod 84 is connected to the bottom of the grinding block 5.

[0027] like Figure 4 and Figure 5 As shown, the feeding mechanism includes a guide hopper 91, a guide cylinder 92, a spiral feeding shaft 93, a servo motor 94 and a feeding pipe 95. The guide hopper 91 is connected to the lower right part of the sorting frame 1, and the guide hopper 91 is located at the lower right part of the guide net 7, so that the guide net 7 can discharge the feed to the guide hopper 91. The guide hopper 91 is connected to the middle of the guide cylinder 92. The upper part of the guide cylinder 92 passes through the sorting frame 1, and the lower front part of the guide cylinder 92 is provided with an opening. The spiral feeding shaft 93 is rotatably connected in the guide cylinder 92. A servo motor 94 is installed on the top of the guide cylinder 92. The output shaft of the servo motor 94 is connected to the spiral feeding shaft 93, and a feeding pipe 95 is connected between the guide cylinder 92 and the grinding frame 2.

[0028] When it is necessary to grind pet feed, the present grinding device can be used. When in use, the feed is first put into the grinding frame 2 through the feeding barrel 3, and the feed in the grinding frame 2 will enter between the grinding frame 2 and the grinding chamber. At the same time, the driving motor 4 can be controlled to drive the grinding block 5 to rotate. The grinding block 5 can cooperate with the grinding chamber to grind the feed during rotation, and the ground feed will fall on the screening cone 82, the screening net 81 and the baffle plate 83. The feed on the baffle plate 83 will slide along the inclined surface at the top of the baffle plate 83 to the screening cone 82 and the screening net 81, and the feed with qualified particle size after grinding will pass through the screening cone 82 and the screening net 81 and fall into the material guide net 7, and then fall into the collection frame 6 through the material guide net 7, and be collected by the collection frame 6, while the unqualified feed with larger particle size will remain on the screening net 81 and the screening cone 82 The surface, when the grinding block 5 rotates, it can drive the V-shaped sweeping rod 84 to rotate. The rotation of the V-shaped sweeping rod 84 can sweep the feed with larger particle size to the opening, so that the feed falls to the guide net 7 through the opening. The feed with larger particle size is difficult to pass through the guide net 7 and will slide to the right along the guide net 7, thereby sliding into the guide hopper 91. In the process, the feed with qualified particle size can be screened again by 7 and then enter 6 to achieve multi-layer screening; then enter the guide cylinder 92 through the opening, and the spiral feeding shaft 93 is driven to rotate by the servo motor 94. When the spiral feeding shaft 93 rotates, it can transport the feed upward and then send it into the grinding frame 2 through the feeding pipe 95, so that the feed is ground again. This is repeated, the effect of grinding the feed can be achieved, and the ground feed can be screened to avoid the discharge of feed with unqualified particle size.

[0029] like Figure 5 and Figure 7 As shown, a scraper plate 102 is also included. The bottom of the spiral feed shaft 93 is connected to the scraper plate 102. The scraper plate 102 is sleeved on the guide hopper 91 and contacts the inner wall and the outer wall of the guide hopper 91, so that the spiral feed shaft 93 can drive the scraper plate 102 to scrape off the feed attached to the inner wall of the guide hopper 91 when rotating.

[0030] During the rotation of the spiral feeding shaft 93, the scraper plate 102 can be driven to rotate together. The scraper plate 102 can scrape off the feed attached to the inner wall of the guide hopper 91 during rotation, effectively preventing the feed from adhering to the inner wall of the guide hopper 91, thereby ensuring the smooth feeding process and full utilization of the feed, reducing waste and maintaining the cleanliness of the equipment. In this way, not only the feeding efficiency is improved, but also the risk of deterioration due to residual feed is reduced, thereby extending the service life of the equipment.

[0031] like Figure 8As shown, a locking mechanism is also included, and the locking mechanism includes a locking rod 111 and a locking block 112. The left side of the collection frame 6 is rotatably connected to the locking rod 111, and the left side of the sorting frame 1 is connected to the locking block 112. The locking block 112 is provided with a slot that can accommodate the locking rod 111. The locking rod 111 is stuck in the slot, which can lock the collection frame 6 to prevent the collection frame 6 from moving at will.

[0032] When the collecting frame 6 is located in the sorting frame 1, the locking rod 111 can be rotated to engage in the slot of the locking block 112, thereby fixing the collecting frame 6 to prevent the position of the collecting frame 6 from shifting during the grinding process. When the collecting frame 6 needs to be taken out, the locking rod 111 is rotated to disengage from the slot, and then the collecting frame 6 can be pulled out.

[0033] like Figure 1 As shown, an air supply fan 12 is also included. The inner top of the grinding frame 2 is equipped with the air supply fan 12. By controlling the operation of the air supply fan 12, a downward airflow can be generated in the grinding frame 2. This airflow can assist the downward transmission of the feed, and helps the smooth flow of the feed under the action of gravity, ensuring that the feed can be transported to the next processing link more evenly and efficiently, while also improving the efficiency of the entire grinding and transmission process.

[0034] like Figure 1 As shown, a vibration motor 13 is also included. The vibration motor 13 is installed on the front and rear sides of the grinding frame 2. By controlling the operation of the vibration motor 13, the grinding frame 2 can vibrate. This vibration can effectively prevent the feed from adhering to the inner wall of the grinding frame 2 during the grinding process, avoid the inner wall contamination or blockage caused by feed residue, ensure the cleanliness of the inside of the grinding frame 2, and also improve the feed processing efficiency and the operation stability of the equipment.
