Description

Technical Field

[0001] This invention relates to the field of pet food processing technology, specifically a processing machine for pet food. Background Technology

[0002] Pet food, as the primary food source for pets, includes dry food and wet food. Dry food typically refers to dry pet food, while wet food includes canned food, fresh-packaged food, etc. Pet food can meet most of a pet's nutritional needs and is the foundation of their daily diet. During the machining process, pet food is usually prepared in pellet form. Pelletized pet food has the following advantages: 1. It is convenient to feed, easy to measure accurately, and convenient to distribute, effectively controlling a pet's diet; 2. It conforms to a pet's chewing habits, aiding digestion and absorption; 3. It is easy to store, convenient to package, easy to store and transport, and also helps maintain the freshness and taste of the pet food; 4. It meets different needs: according to the pet's age, size, activity level, and nutritional needs, it can be made into different sizes and shapes to suit different pets' requirements. Therefore, pelleted pet food, as the main component of a pet's daily diet, is the food consumed in the largest quantity.

[0003] There are many types of granular pet food, such as freeze-dried beef granules, freeze-dried beef liver granules, and freeze-dried egg yolk granules. During the processing of granular pet food, unsuitable powdery particles may be encountered. Excessive powder can lead to low-quality pet food if directly packaged, making it unsellable. Therefore, after the pet food granules are formed, screening equipment is usually used to remove the powdery particles. However, most existing screening equipment uses vibrating screens, which have excessively high vibration frequencies, easily increasing the breakage of the finished product and resulting in low screening efficiency. Therefore, those skilled in the art have provided a processing machine for pet food to solve the problems mentioned in the background. Summary of the Invention

[0012] As a further embodiment of the present invention: the screening filter plate has a frustum-shaped structure, and the mesh of the screening filter plate and the support plate of the spiral guide plate are arranged in a staggered manner.

[0013] As a further embodiment of the present invention: the crushing assembly includes a transmission seat fixed to the transmission shaft shaft and a crushing filter plate fixed to the wall of the processing tank along the circumference of the transmission seat. The outer side of the support of the transmission seat is arranged in a star-triangle pattern with a crushing roller, a rotary cutting roller, and a cleaning brush roller opposite to the crushing filter plate. The edge of the crushing filter plate is provided with a transmission gear plate.

On the one hand, the spiral and centrifugal drive of the screening assembly gradually screens the granular pet food while simultaneously circulating and discharging the finished granular pet food, replacing the traditional vibrating screening method. This results in more stable screening and a lower screening damage rate. On the other hand, the roller crushing of the crushing assembly simultaneously crushes and screens the defective products after screening, which are then circulated and discharged through the feeding assembly. This achieves integrated screening, crushing, and recycling of granular pet food, resulting in more efficient screening quality and more comprehensive handling of defective products after screening.

[0028] Please see Figures 1-8 In this embodiment of the invention, a pet food processing machine includes a processing tank 1. A brake motor 2 is installed in the middle of the bottom of the processing tank 1, and a spiral feeding assembly perpendicular to the brake motor 2 is installed in the middle of the chamber of the processing tank 1. The spiral feeding assembly includes a push pipe 6 installed in the middle of the chamber of the processing tank 1. The bottom end of the push pipe 6 is connected to a feeding pipe 3 that passes through the processing tank 1, and the top end of the push pipe 6 has a discharge port 12. A rotating shaft 10 opposite to the brake motor 2 is rotatably connected to the middle of the push pipe 6, and the outer side of the shaft of the rotating shaft 10... A spiral feeding auger 11 is fitted to fit against the wall of the push pipe 6. The brake motor 2 is controlled to work as a drive source, driving the combination of the rotating shaft 10 and the spiral feeding auger 11 to rotate, serving as a feeding platform for pet food. Then, the granulated pet food with screening is poured into the push pipe 6 through the feeding pipe 3. The granulated pet food is fed in a quantitative spiral manner by the transmission combination of the rotating shaft 10 and the spiral feeding auger 11, and is discharged in a circular manner through the discharge port 12 to the center of the screening component 7. The feeding is simpler, easier and more convenient, without the need to raise the pet food for feeding.

[0029] A parallel braking assembly is installed through the bottom of the chamber of processing tank 1. From top to bottom, a screening assembly 7, a crushing assembly 8, and a feeding assembly 9 are sequentially arranged around the spiral feeding assembly on the outer side of the drive shaft 17 of the parallel braking assembly. The parallel braking assembly includes a brake shaft 14 horizontal to the output direction of the brake motor 2 and penetrating the bottom of the processing tank 1, and a differential gear B16 rotatably connected to the interior of the processing tank 1 and surrounding the spiral feeding assembly. A differential gear A15 meshes with the differential gear B16 at the top of the brake shaft 14, and a transmission belt 13 connected to the brake motor 2 is installed at the bottom of the brake shaft 14. The drive shaft 17 is symmetrically arranged in a star-triangle pattern on the upper end of the gear plate of the differential gear B16. The output end of the brake motor 2 is... The device includes a differential pulley A18 and a differential pulley B19 at the bottom of the shaft of the brake shaft 14. The differential pulleys A18 and B19 are connected by a transmission belt 13. When the brake motor 2 is working, it drives the differential pulley A18 to rotate. Through the transmission belt 13, the differential pulley B19 is driven to rotate, which in turn drives the brake shaft 14 to rotate. As the brake shaft 14 rotates, it drives the differential gear A15 to rotate. Through the meshing transmission between the differential gear A15 and the differential gear B16, the transmission shaft 17 is driven to rotate around the differential gear B16. This, in turn, drives the combination of the screening component 7, the crushing component 8, and the feeding component 9 to rotate in parallel, performing integrated screening, crushing, and recycling of granular pet food.

[0030] The processing tank 1 has a finished product discharge port 4 horizontally opposite to the screening assembly 7. The screening assembly 7 includes a screening filter plate 71 fixedly installed on the shaft of the drive shaft 17, and a material collecting side plate 74 fixed circumferentially to the tank wall of the processing tank 1 along the screening filter plate 71. A spiral guide plate 72 is provided at the upper end of the screen of the screening filter plate 71, and multiple sets of pusher plates 73 opposite to the material collecting side plate 74 are arranged circumferentially along the edge of the screening filter plate 71. The screening filter plate 71 has a frustum-shaped structure, and the mesh of the screening filter plate 71 and the support plate of the spiral guide plate 72 are staggered. When the drive shaft 17 rotates, it drives... The combined rotation of the screening filter plate 71 and the spiral guide plate 72 utilizes the centrifugal rotation of the screening filter plate 71 and the spiral guidance of the spiral guide plate 72 to push the granular pet food in the center outward in a spiral motion. At the same time, unqualified pet food is screened out, while qualified pet food slides onto the collection side plate 74 under the centrifugal push of the spiral. Then, under the rotation of the pusher plate 73 driven by the screening filter plate 71, the qualified pet food is discharged through the finished product discharge port 4 in a circulating manner. This replaces the traditional vibrating screening method, which not only makes the screening more stable but also extends the screening time and ensures the quality.

[0031] The crushing assembly 8 includes a transmission seat 81 fixed to the shaft of the transmission shaft 17, and a crushing filter plate 83 fixed circumferentially to the wall of the processing tank 1 along the transmission seat 81. A crushing roller 84, a rotary cutting roller 86, and a cleaning brush roller 88 are arranged in a star-triangle pattern on the outer side of the transmission seat 81, opposite to the crushing filter plate 83. A transmission gear disc 82 is provided on the edge of the crushing filter plate 83. A first irregular gear 85 meshing with the transmission gear disc 82 is provided at one end of the roller shaft of the crushing roller 84. A second irregular gear 87 meshing with the transmission gear disc 82 is provided at one end of the roller shaft of the rotary cutting roller 86. A third irregular gear 89 meshing with the transmission gear disc 82 is provided at one end of the roller shaft of the cleaning brush roller 88. The roller body of the crushing roller 84 has a smooth structure. The roller body of the rotary cutting roller 86 has multiple sets of rotary cutting blade rings arranged at equal intervals. The roller body of the cleaning brush roller 88 is symmetrical. The device is equipped with two sets of opposing spiral cleaning brushes. As the drive shaft 17 rotates, it drives the drive base 81 to rotate as well. During the rotation of the drive base 81, the combination of crushing roller 84, rotary cutting roller 86, and cleaning brush roller 88 rotates synchronously. Simultaneously, the first, second, and third shaped gears at one end of each roller shaft mesh with the drive gear disc 82, allowing the three roller shafts to rotate while maintaining their own rotation. Then, the combination of crushing roller 84, rotary cutting roller 86, and cleaning brush roller 88 performs roller crushing, rotary cutting, and cleaning of the sieved substandard pet food. After crushing, the substandard pet food is filtered and recycled, eliminating the need for further processing by workers and reducing their workload.

[0032] The processing tank 1 has a slag discharge port 5 that is horizontally opposite to the material feeding assembly 9. The material feeding assembly 9 includes a rotating seat 91 fixed on the shaft of the drive shaft 17 and a baffle plate 92 fixed circumferentially to the tank wall of the processing tank 1 along the rotating seat 91. The outer side of the support of the baffle plate 92 is symmetrically arranged in a star-triangle pattern with a material feeding paddle 93 that fits against the baffle plate 92. When the drive shaft 17 rotates, it drives the rotating seat 91 to rotate, which in turn drives the material feeding paddle 93 to rotate centrifugally. The pet food that has been crushed and fallen onto the baffle plate 92 is centrifugally discharged through the slag discharge port 5. The unqualified pet food particles after screening are crushed and recycled in an integrated manner, reducing subsequent operation processes.

[0033] The working principle of this invention is as follows: When performing a screening process on pet food after freeze-drying and granulation, the brake motor 2 is controlled to work, driving the combination of the rotating shaft 10 and the spiral feeding auger 11 to rotate, serving as a feeding platform for pet food. Then, the granulated pet food with screening is circulated into the pushing pipe 6 through the feeding pipe 3. Using the transmission combination of the rotating shaft 10 and the spiral feeding auger 11, the granulated pet food is quantitatively spirally fed, and then circulatedly discharged through the discharge pipe 12 to the center of the screening component 7, so that the screening component 7 can perform a step-by-step screening of the pet food from the inside out.

[0034] While the brake motor 2 is working, it drives the combination of differential pulley A18, transmission belt 13, and differential pulley B19 to rotate synchronously, which in turn drives the brake shaft 14 to rotate. As the brake shaft 14 rotates, it drives the combination of differential gear A15 and differential gear B16 to mesh and drive the transmission shaft 17 to rotate around the differential gear B16 as the axis. This, in turn, drives the combination of screening component 7, crushing component 8, and feeding component 9 to rotate in parallel, performing integrated screening, crushing, and recycling of granular pet food.

[0035] As the drive shaft 17 rotates, it drives the combined rotation of the screening filter plate 71 and the spiral guide plate 72. Utilizing the centrifugal rotation of the screening filter plate 71 and the centrifugal spiral guidance of the spiral guide plate 72, the granular pet food in the center is gradually spiraled outward. While pushing, unqualified pet food is screened out, and qualified pet food gradually slides onto the collection side plate 74 under the centrifugal push of the spiral. Under the synchronous rotation of the pusher plate 73 driven by the screening filter plate 71, the qualified pet food on the collection side plate 74 is circulated and discharged through the finished product discharge port 4, realizing a smooth screening operation for granular pet food. The screening is smoother and more stable, while ensuring the screening quality.

[0036] As the transmission shaft 17 rotates, it drives the transmission seat 81 to rotate. During the rotation of the transmission seat 81, the combination of crushing roller 84, rotary cutting roller 86, and cleaning brush roller 88 rotates synchronously. While the crushing roller 84, rotary cutting roller 86, and cleaning brush roller 88 are rotating, the meshing of the first special gear 85, the second special gear 87, and the third special gear 89 at one end of their roller shafts with the transmission gear plate 82 enables the three sets of roller shafts to rotate while maintaining their own rotation. By utilizing the combination of the revolution and rotation of the crushing roller 84, rotary cutting roller 86, and cleaning brush roller 88, the unqualified pet food that falls onto the crushing filter plate 83 after screening is crushed by roller pressing, rotary cutting, and cleaning. The unqualified pet food is then filtered and recycled, reducing the workload of subsequent operations.

[0037] As the drive shaft 17 rotates, it drives the rotating seat 91 to rotate, which in turn drives the feeding paddle 93 to rotate centrifugally, so that the pet food powder that has fallen onto the baffle plate 92 is discharged centrifugally through the slag discharge port 5.

[0038] It can perform high-quality centrifugal screening of granular pet food, and simultaneously crush and recycle defective products in an integrated manner, reducing subsequent operation processes and making it more suitable for widespread use.
