Description

Technical Field

[0001] The present invention relates to the technical field of cat food production and processing, and particularly relates to a crushing device and method for processing cat food raw materials. Background Art

[0002] The raw materials of cat food usually include several main parts such as meat, grains, vegetables, and additives, among which meat is one of the most important components. Meat is rich in proteins, amino acids, and essential fatty acids, which can meet the nutritional needs of cats for growth and normal metabolism. When processing meat, it is necessary to crush the meat used for making cat food.

[0003] A chicken breast meat shredding device in cat food production and processing described in the publication number: CN118892901A includes a support frame and a mixing and granulating device. A shredding component is installed on the top of the support frame, a locking component is arranged in the middle of the support frame, and a dispersing component is arranged inside the rear end of the support frame. An outlet meat cover and a fixing frame are installed at one end of the shredding component close to the dispersing component; the shredding component includes a first motor and a shredding roller. A top cover is movably connected to the upper side of the shredding roller. A feed inlet is opened at the top of the side of the top cover close to the first motor. A pair of fixed tubes are fixedly connected to the top of the first motor; the support frame is located on the top of the mixing and granulating device and the support frame is fixedly connected to the mixing and granulating device. The first motor is fixedly connected to the middle of the support frame. The shredding roller is rotatably connected to the support frame. The first motor is in transmission connection with the shredding roller. The top cover is slidably connected to the support frame.

[0004] Based on the above technical features, the problems that occur are as follows: In the prior art, after the device produces cat food raw materials for a long time, it is necessary to clean the shredding roller for crushing cat food raw materials, as well as mechanisms in contact with cat food raw materials such as the top cover, outlet meat cover, and support frame, to prevent the growth of bacteria and affect the product quality of cat food raw materials. However, since meat is prone to produce sticky substances such as blood and grease during crushing, the sticky substances are likely to remain in the gaps of the device. After long-term use, the sticky substances deep in the gaps are likely to solidify and thus generate an adhesive ability. The existing top cover needs to be manually disassembled from the support frame, with low automation. And due to the adhesion caused by the solidification of the sticky substances, the disassembly difficulty is increased, and the labor intensity is increased.

[0005] Therefore, it is very necessary to solve the above problems through a crushing device and method for processing cat food raw materials. Summary of the Invention

[0073] A method for crushing raw materials for processing cat food, the detection method uses the above-mentioned crushing device for processing raw materials for cat food. The method comprises the following steps: first, the meat outlet round cover 11 is clamped with the lower half cylinder 4. Then, the upper half cylinder 6 is turned upside down on the lower half cylinder 4 and the meat outlet round cover 11 is clamped with the upper half cylinder 6.

[0074] After that, all the cylinders 34 are started for the first time. The telescopic shafts of the cylinders 34 retract and drive the hinge seats to revolve around the support shaft 16. The hinge seats drive the swivel ring 29 to rotate. The swivel ring 29 drives the transmission plate 30 to revolve around the support shaft 16. The transmission plate 30 pushes the limit block to revolve around the support shaft 16. The limit block drives the slip ring 25 to rotate. The slip ring 25 drives the second magnet 28 to revolve around the support shaft 16. Previously, the second magnet 28 was magnetically attracted to the first magnet 19. Therefore, when the second magnet 28 revolves around the support shaft 16, it makes sliding contact with the first magnet 19. During this process, the second magnet 28 slides along the first magnet 19 and gradually slides to the upper left of the support shaft 16. At the same time, the slip ring 25 pushes the arc-shaped pull block 24 to rotate synchronously through the internal arc spring 27. The arc-shaped pull block 24 drives the pressing block 20 to rotate synchronously.

[0075] When the stop block 21 in the perforation of the pressing block 20 contacts and abuts against the stop bar 17, the arc spring 27 is compressed. At this time, the pressing block 20 is in a vertical state. As the slip ring 25 continues to rotate, the second magnet 28 gradually disengages from the first magnet 19. When the second magnet 28 disengages from the first magnet 19, the cylinder 34 is shut down. After that, under the elastic force of the spring 31, the limit block slides downward close to the lower half cylinder 4 and drives the slip ring 25 to slide upward close to the upper half cylinder 6. The slip ring 25 pushes the pressing block 20 to move upward close to the upper half cylinder 6 through the arc-shaped pull block 24. During this process, the stop block 21 makes sliding contact with the stop bar 17.

[0076] When the bottom end of the pressing block 20 contacts and abuts against the slider 32, the cylinder 34 is started for the second time. At this time, the telescopic shaft of the cylinder 34 extends and pushes the hinge seat to revolve around the support shaft 16 in the reverse direction. The hinge seat drives the swivel ring 29 to rotate in the reverse direction. The swivel ring 29 drives the transmission plate 30 to revolve around the support shaft 16 in the reverse direction. The transmission plate 30 drives the slider 32 to revolve around the support shaft 16 in the reverse direction. At the same time, the transmission plate 30 pushes the limit block to revolve around the support shaft 16 in the reverse direction. The limit block drives the slip ring 25 to rotate in the reverse direction. During this process, due to the elastic force of the arc spring 27, the arc-shaped pull block 24 is in a static state, the pressing block 20 is in a static state, the arc spring 27 elongates, and the slider 32 makes sliding contact with the pressing block 20.

[0077] As the transmission plate 30 continues to revolve, the slider 32 slides to the notch 23 at the bottom end of the pressing block 20. At the same time, the slip ring 25 rotates to contact the end of the arc-shaped pull block 24 away from the arc spring 27. At this time, the cylinder 34 is shut down. Subsequently, under the elastic force of the spring 31, the pressing block 20 continues to slide close to the upper half cylinder 6 and finally drives the rubber pad to abut against the upper half cylinder 6. During this process, the slider 32 enters the chute 22 from the notch 23 relative to the pressing block 20.

[0078] After that, the third time the cylinder 34 is started, the telescopic shaft of the cylinder 34 retracts and drives the hinge seat to revolve around the support shaft 16. The hinge seat drives the swivel ring 29 to rotate. The rotation direction of the swivel ring 29 is the same as that when the cylinder 34 is started for the first time. During this process, the swivel ring 29 drives the transmission plate 30 to revolve around the support shaft 16 and drives the slider 32 and the limit block to revolve around the support shaft 16 synchronously. At this time, the slider 32 slides along the chute 22 and gradually abuts against the pressing block 20 in the revolution direction. At the same time, since the stop block 21 abuts against the stop strip 17, the limit block drives the slip ring 25 to rotate and compress the arc spring 27 until the slider 32 abuts against the pressing block 20 in the revolution direction.

[0079] Then, the cylinder 34 is shut down. At this time, all the pressing blocks 20 are pressed on the lower half cylinder 4, and the lower half cylinder 4 and the upper half cylinder 6 together form a meat grinding cylinder.

[0080] Next, cat food raw materials are added into the meat grinding cylinder through the feeding port 7. At the same time, the motor 13 and the driving motor are started. The output shaft of the motor 13 drives the crushing roller 14 to rotate, and the crushing roller 14 drives the spiral conveying blade and the crushing knife to rotate. During this process, the spiral conveying blade pushes the cat food raw materials to the crushing blade, and the crushing blade crushes the cat food raw materials. The crushed cat food raw materials are extruded from the meat outlet holes of the meat outlet round cover 11 and fall into the blanking port 3.

[0081] The cat food raw materials falling into the blanking port 3 are secondarily crushed by the minced meat blades on the rotating roller 35. After being secondarily crushed, the cat food raw materials fall into the collection box 1 and are subjected to subsequent processing.

[0082] After all the cat food raw materials are crushed, the cylinder 34 is started for the fourth time, and the telescopic shaft of the cylinder 34 extends. During this process, the telescopic shaft of the cylinder 34 pushes the hinge seat, the hinge seat drives the swivel ring 29, the swivel ring 29 drives the transmission plate 30, and the transmission plate 30 drives the slider 32 to slide along the chute 22 to the notch 23. At this time, the transmission plate 30 pushes the limit block, and the limit block pushes the slip ring 25 to rotate until it contacts the end of the arc pull block 24 away from the arc spring 27. After that, as the telescopic shaft of the cylinder 34 continues to extend, the swivel ring 29, the slip ring 25, and the pressing block 20 rotate synchronously, and at the same time, the transmission plate 30, the limit block, the slider 32, and the arc pull block 24 revolve around the support shaft 16 synchronously. During this process, the slip ring 25 pushes the arc pull block 24 to rotate synchronously, and the arc pull block 24 drives the pressing block 20 to rotate closer to the push block 8.

[0083] When the briquetting block 20 rotates and approaches the pushing block 8, it makes a sliding contact with the upper half cylinder 6. The upper half cylinder 6 pushes the briquetting block 20 to move radially away from the lower half cylinder 4 along the lower half cylinder 4. During this process, the slider 32 moves out of the notch 23 relative to the briquetting block 20, and the spring 31 is compressed. As the briquetting block 20 continues to rotate and approach the pushing block 8, the briquetting block 20 contacts and makes a sliding contact with the transmission inclined surface 9 at the top of the pushing block 8. At this time, the pushing block 8 continues to push the briquetting block 20 to move radially away from the lower half cylinder 4 along the lower half cylinder 4.

[0084] When the briquetting block 20 disengages from the pushing block 8 and rotates to the lower side of the pushing block 8, under the elastic force of the spring 31, the sliding ring 25, the arc pulling block 24, and the briquetting block 20 synchronously move radially close to the lower half cylinder 4 along the lower half cylinder 4. When the briquetting block 20 contacts and abuts against the lower half cylinder 4, the telescopic shaft of the cylinder 34 retracts. At this time, the telescopic shaft of the cylinder 34 pulls the hinge seat, the hinge seat drives the rotating ring 29, the rotating ring 29 drives the transmission plate 30, the transmission plate 30 pushes the limiting block, and the limiting block drives the sliding ring 25 to reverse. During this process, the sliding ring 25 pushes the arc pulling block 24 to reverse through the arc spring 27, and the arc pulling block 24 drives the briquetting block 20 to reverse and contact the bottom of the pushing block 8. As the sliding ring 25 continues to reverse, the arc spring 27 is gradually compressed, and the elastic force of the arc spring 27 on the arc pulling block 24 increases. At the same time, the pushing force of the arc pulling block 24 on the briquetting block 20 increases, and the pushing force of the briquetting block 20 on the pushing block 8 increases. When the pushing force of the pushing block 8 on the briquetting block 20 is greater than the adhesion force of the viscous substance between the upper half cylinder 6 and the lower half cylinder 4, the upper half cylinder 6 is separated from the lower half cylinder 4. After that, the upper half cylinder 6 is removed, and at the same time, the telescopic shaft of the cylinder 34 extends again.

[0085] After the upper half cylinder 6 is removed, under the elastic force of the arc spring 27, the arc pulling block 24 drives the briquetting block 20 to continue to reverse until the end of the arc pulling block 24 away from the arc spring 27 abuts against the sliding ring 25 again.

[0086] When the telescopic shaft of the cylinder 34 extends again, the hinge seat of the cylinder 34 pushes the rotating ring 29, the rotating ring 29 drives the transmission plate 30, the transmission plate 30 pushes the limiting block, the limiting block drives the sliding ring 25, the sliding ring 25 pushes the arc pulling block 24, and the arc pulling block 24 drives the briquetting block 20 to rotate and approach the inclined surface block 33 and finally contact the inclined surface at the top of the inclined surface block 33. After the briquetting block 20 contacts the inclined surface at the top of the inclined surface block 33, it makes a sliding contact with the inclined surface at the top of the inclined surface block 33, and the inclined surface block 33 pushes the briquetting block 20 to move radially away from the lower half cylinder 4 along the lower half cylinder 4. During this process, the briquetting block 20 pushes the arc pulling block 24, the arc pulling block 24 pushes the sliding ring 25 to move close to the mounting post 15, and the sliding ring 25 drives the limiting block to compress the spring 31. At this time, the sliding ring 25 drives the second magnet 28 to gradually approach the first magnet 19 and finally contact the first magnet 19 to form magnetic attraction.

[0087] Finally, shut down the cylinder 34, and clean the upper half cylinder 6, the lower half cylinder 4, the round cover 11 of the meat outlet, and the parts in contact with the cat food raw materials.
