Description

Technical Field

[0001] This utility model relates to the field of feed production technology, and in particular to a raw material cutting device for pet food production. Background Technology

[0002] Feed is a general term for the food consumed by all domesticated animals. In a narrower sense, feed generally refers to the food raised in agriculture or animal husbandry. The main raw materials for feed include more than ten varieties such as soybeans, soybean meal, corn, fishmeal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. Through precise formulation, these are made into food that meets the growth needs of animals. Before pet food is pelleted, a raw material crushing and cutting device is used to crush and cut the various raw materials used in feed processing into small pellets. These pellets are then mixed and stirred before the pelleting process.

[0003] For example, Chinese utility model patent application number 202321429487.6 discloses a raw material crushing mechanism for feed processing, including a crushing box. A feeding section is provided at the top of the side wall of the crushing box. Two sets of crushing rollers are arranged vertically on the outer side of the feeding section, and a first driving mechanism is provided in conjunction with the crushing rollers. Both sets of crushing rollers are provided with crushing teeth. Two layers of screens with gradually decreasing apertures are arranged vertically inside the crushing box. A stirring shaft is rotatably installed inside the crushing box through bearings, and a first motor is provided in conjunction with the stirring shaft. Cutting blades are provided on the stirring shaft in conjunction with each screen. A discharge pipe is provided at the bottom of the crushing box, and a discharge auxiliary mechanism is provided in conjunction with the discharge pipe. This utility model can perform sufficient pre-crushing and grinding before fully cutting and crushing feed raw materials, thereby improving crushing efficiency and crushing quality.

[0004] The aforementioned patent, when crushing and cutting raw materials for feed processing, can only crush and cut multiple raw materials sequentially, and cannot crush and cut multiple raw materials simultaneously. This results in the raw materials after crushing and cutting easily becoming layered, which is not conducive to the subsequent rapid and convenient uniform mixing of multiple crushed and cut raw materials. Furthermore, the distance between the crushing rollers in the aforementioned patent cannot be adjusted, making it inconvenient to crush and cut raw materials into the required particle size according to the type of feed production, and thus failing to meet the production needs of different types of feed.

[0005] Therefore, it is necessary to provide a raw material cutting device for pet food production to solve the above-mentioned technical problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0030] Reference Figure 1-7 The present invention provides a raw material cutting device for pet food production: including a mixing box 1, a plurality of crushing boxes 2 are fixedly connected to the top of the mixing box 1, a fixed crushing mechanism 3 is provided inside the plurality of crushing boxes 2, and an adjustment mechanism 4 is also provided on one side of the crushing box 2.

[0031] The adjusting mechanism 4 includes a threaded adjusting rod 401 rotatably mounted on one side of the crushing box 2. The outer surface of the threaded adjusting rod 401 is threadedly connected to a threaded adjusting block 402. A U-shaped adjusting frame 403 is fixedly sleeved on the outer surface of the threaded adjusting block 402. A movable crushing mechanism 5 is provided on the U-shaped adjusting frame 403.

[0032] The adjusting mechanism 4 is used to adjust the position of the movable crushing mechanism 5, thereby adjusting the distance between the movable crushing mechanism 5 and the fixed crushing mechanism 3. Inclined guide plates 12 are fixedly installed on both sides of the inner wall of the crushing box 2 and above the fixed crushing mechanism 3 and the movable crushing mechanism 5, which are used to guide the raw materials to be crushed and cut into the crushing box 2 to the space between the fixed crushing mechanism 3 and the movable crushing mechanism 5.

[0033] A locking mechanism 6 for limiting the threaded adjusting rod 401 is provided on one side of the crushing box 2. The locking mechanism 6 includes a device frame 601 and a limiting plate 602. The device frame 601 is fixedly installed on one side of the crushing box 2, and the limiting plate 602 is fixedly sleeved on one end of the threaded adjusting rod 401. The outer surface of the limiting plate 602 has several locking holes 603 arranged in a circumferential array. A slider 604 is slidably connected inside the device frame 601. A locking rod 605 is fixedly connected to the bottom of the slider 604. The bottom end of the locking rod 605 moves through the device frame 601 and is inserted into the corresponding locking hole 603. A compression spring 606 is fixedly connected between the top of the slider 604 and the top of the inner wall of the device frame 601. A pull rod 607 is fixedly connected to the side of the slider 604 away from the crushing box 2. By setting the locking mechanism 6, the threaded adjusting rod 401 can be limited and fixed, preventing the threaded adjusting rod 401 from rotating due to vibration during subsequent equipment operation, which would cause the position of the movable crushing mechanism 5 to shift.

[0034] A guide ring 404 is fixedly inserted through the U-shaped adjusting frame 403. A guide rod 405 is movably inserted inside the guide ring 404. One end of the guide rod 405 is fixedly connected to the crushing box 2.

[0035] The fixed crushing mechanism 3 includes a drive motor 301 fixedly installed on one side of the crushing box 2. The output end of the drive motor 301 is fixedly connected to a rotating shaft 302. A crushing roller 303 is fixedly sleeved on the outer surface of the rotating shaft 302. The rotating shaft 302 is rotatably connected to the inner wall of the crushing box 2.

[0036] The active crushing mechanism 5 includes a second drive motor 501 fixedly installed on one side of the U-shaped adjusting frame 403. The output end of the second drive motor 501 is fixedly connected to a second rotating shaft 502. A crushing roller 503 is fixedly sleeved on the outer surface of the second rotating shaft 502. An avoidance slot 11 is provided on the crushing box 2 at the position corresponding to the second rotating shaft 502, so that the second rotating shaft 502 can move relative to the crushing box 2. The U-shaped adjusting frame 403 plays a role in blocking the avoidance slot 11, which can prevent the raw material from leaking out from the avoidance slot 11 during the crushing process.

[0037] The mixing chamber 1 is equipped with a stirring mechanism 7. The stirring mechanism 7 includes a drive motor 701 fixedly installed at the middle position of the top of the mixing chamber 1. The output end of the drive motor 701 is fixedly connected to a stirring shaft 702. The outer surface of the stirring shaft 702 is fixedly connected to a stirring frame 703. The drive motor 701 is turned on by the control panel 10. The output end of the drive motor 701 drives the stirring shaft 702 and the stirring frame 703 to rotate, thereby stirring and mixing the various raw materials that have been crushed and cut in the mixing chamber 1.

[0038] The bottom of the mixing box 1 is fixedly connected to a discharge pipe 8, and a solenoid valve 9 is installed on the discharge pipe 8. The front of the mixing box 1 is equipped with a control panel 10, which is electrically connected to the solenoid valve 9. The drive motor 1 301, drive motor 2 501, and drive motor 3 701 are all electrically connected to the control panel 10.

[0039] The solenoid valve 9 is used to control the opening and closing of the discharge pipe 8. After the various raw materials in the mixing box 1 are mixed, the solenoid valve 9 is opened through the control panel 10, so that the discharge pipe 8 is in the open state, and then the raw materials in the mixing box 1 are discharged downward by gravity.

[0040] Working principle: When it is necessary to crush and cut various raw materials for pet food production, first adjust the particle size of the raw materials according to the type of feed to be produced. Hold the pull rod 607 and move it upward, which will drive the slider 604 and locking rod 605 to move upward. The upward movement of the slider 604 compresses the compression spring 606, putting it in a compressed state and storing energy. Continue to move the pull rod 607 upward until the locking rod 605 pushes out of the locking hole 603, releasing the limiting plate 602. At this time, adjust the threaded rod by turning it. 401. Under the limiting action of the guide rod 405 and the guide ring 404 on the U-shaped adjusting frame 403, the threaded adjusting block 402 moves along the axial direction of the threaded adjusting rod 401, and drives the U-shaped adjusting frame 403 to move, thereby driving the movable crushing mechanism 5 to move relative to the fixed crushing mechanism 3, so as to adjust the distance between the fixed crushing mechanism 3 and the movable crushing mechanism 5. That is, by adjusting the distance between the first crushing roller 303 and the second crushing roller 503, the particle size of the raw material crushing and cutting is adjusted.

[0041] After the distance between the fixed crushing mechanism 3 and the movable crushing mechanism 5 is adjusted according to the needs of feed production, the pull rod 607 is released, and the locking rod 605 is pushed down by the elastic force of the compression spring 606 so that it is inserted into the locking hole 603 on the limiting plate 602, and the limiting plate 602 is fixed again, thereby achieving the limiting and fixing of the threaded adjustment rod 401, and preventing the threaded adjustment rod 401 from rotating due to vibration during subsequent equipment operation, which would cause the position of the movable crushing mechanism 5 to shift.

[0042] Subsequently, the staff added various raw materials for feed production that needed to be crushed and shredded into multiple crushing boxes 2. The first drive motor 301 and the second drive motor 501 were started through the control panel 10. The first drive motor 301 and the second drive motor 501 drove the first crushing roller 303 and the second crushing roller 503 to rotate in opposite directions, crushing and shredding the raw materials in the crushing box 2. The crushed and shredded raw materials fell into the mixing box 1 by gravity. At the same time, the third drive motor 701 was turned on through the control panel 10. The output end of the third drive motor 701 drove the stirring shaft 702 and the stirring frame 703 to rotate, stirring and mixing the various crushed and shredded raw materials in the mixing box 1.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
