Description

Technical Field

[0001] This utility model relates to the field of pet food processing technology, specifically to a grading and screening device for pet food processing. Background Technology

[0002] Pet food refers to food specifically designed for pets (such as cats and dogs) to meet their nutritional needs at different life stages or under specific physiological or pathological conditions. It falls between human food and traditional livestock feed, belonging to the category of high-end animal food. In pet food processing, grading and sorting equipment is used to separate pet food products of different sizes. For example:

[0003] Chinese Patent Publication No. CN216460108U discloses a grading and screening device for pet food processing, relating to the field of pet food processing technology. The device includes a screening box with a feed hopper fixedly connected to its upper surface. The inner wall of the screening box is equipped with a first sieve plate and a second sieve plate, and a guide plate is also installed on the inner wall. Through the coordinated arrangement of the screening box, feed hopper, first sieve plate, second sieve plate, guide plate, discharge pipe, and cleaning components, pet food is fed into the screening box through the feed hopper. The first sieve plate performs preliminary screening of the pet food. Smaller pieces of pet food, after screening, fall onto the left end of the second sieve plate via the guide plate, where the second sieve plate performs further screening. The cleaning components clean the sieve plates, enabling the device to grade and screen pet food. Simultaneously, the device automatically cleans the sieve plates, ensuring effective screening.

[0004] Based on existing solutions and actual production and processing applications, current grading and sorting equipment used in pet food processing still has some problems, such as:

[0005] When sorting pet food, the sorting relies on the pet food sliding down the sieve plate due to gravity. However, this method has limited sorting effectiveness and thus affects the efficiency of pet food grading and sorting.

[0006] When pet food is being screened, unscreened pet food will be discharged through the discharge pipe located on the upper right side of the screening box, thus affecting the screening effect. Therefore, this utility model provides a grading and screening device for pet food processing to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a grading and screening device for pet food processing, in order to solve the problems mentioned in the background art, which are limited in their screening effect when pet food is screened by gravity as it slides down the screen plate, thus affecting the grading and screening efficiency of pet food. In addition, unscreened pet food is discharged through the discharge pipe set on the upper right side of the screening box, which also affects the screening effect of pet food.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a grading and screening device for pet food processing, comprising a box body, an inlet pipe fixedly installed on the upper left side of the box body, an outlet pipe fixedly installed on the middle side of the outer end of the box body, and a sieve plate provided on the inner side of the box body;

[0009] Also includes:

[0010] A fixed plate is fixedly installed on the upper left side of the box body, and a first motor is fixedly installed on the left side of the fixed plate. The output end of the first motor is connected to a moving structure, and the moving structure includes a connecting block and an eccentric wheel. The eccentric wheel is connected to the output end of the first motor, and a connecting block is connected to the upper side of the eccentric wheel.

[0011] A collection frame is movably installed inside the lower side of the box, and a limiting structure is fixedly installed on the outer side of the middle part of the box. The limiting structure includes a baffle plate and a cylinder, and the cylinder is fixedly installed on the outer side of the middle part of the box, and a baffle plate is installed on the lower side of the cylinder.

[0012] Preferably, a spring is fixedly installed on the left side inside the housing, and a moving block is fixedly installed on the lower side of the spring, and a fixed connecting plate is installed on the middle side inside the fixed connecting plate.

[0013] Preferably, a second motor is also provided on the front side of the lower end of the feed pipe, and the output end of the second motor is connected to the connecting rod, and a partition plate is fixedly provided on the outside of the connecting rod.

[0014] Preferably, the sieve plates are inclined and evenly distributed inside the housing, and mounting rods are provided on the inner side of the sieve plates, and the sieve plates are connected to each other through the mounting rods for linkage.

[0015] Preferably, the lower side of the baffle plate is fitted and connected to the lower side of the discharge pipe, and a protrusion structure is provided on the upper middle side of the baffle plate, and the upper side of the baffle plate is fixedly connected to the lower side of the cylinder.

[0016] Preferably, the partition plate and the feed pipe are connected in a close fit, and the partition plate is distributed at equal angles about the center point of the connecting rod.

[0017] Preferably, the movable block and the box are connected by a telescopic sliding connection, which can prevent pet food from being thrown out through the sliding groove of the connecting block.

[0018] Preferably, the lower right end of the connecting block is fixedly connected to the sieve plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the grading and screening equipment for pet food processing is equipped with a moving structure that can vibrate the sieve plate, thereby improving the screening efficiency of pet food, and is equipped with a limiting structure that can block unscreened pet food, thereby improving the screening effect of pet food.

[0020] By starting the second motor, the connecting rod is rotated inside the lower side of the feed pipe, which in turn rotates the partition plate. This causes the pet food inside the partition plate to rotate to the lower side of the feed pipe, allowing the pet food to enter the box through the perforated structure at the bottom of the feed pipe, facilitating quantitative feeding of the pet food.

[0021] By starting the first motor, the first motor drives the eccentric wheel to rotate on the upper side of the fixed plate, thereby causing the eccentric wheel to drive the connecting block to move up and down, which in turn causes the connecting block to drive the sieve plate to move up and down. The sieve plate, through the mounting rod, drives the sieve plate on the lower side of the box to move up and down, thereby causing the sieve plate to vibrate and screen the pet food, ensuring a good grading and screening effect for the pet food.

[0022] The baffle plate installed inside the discharge pipe can block unscreened pet food. Activating the cylinder moves the baffle plate upwards, causing it to separate inside the discharge pipe, thus facilitating the discharge of screened pet food. Attached Figure Description

[0030] 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.

[0031] Please see Figure 1-6 This utility model provides a technical solution: a grading and screening device for pet food processing, comprising: a housing 1, a collection frame 2, a feed pipe 3, a sieve plate 4, a discharge pipe 5, a fixed connecting plate 6, a mounting rod 7, a blocking plate 8, a connecting rod 9, a partition plate 10, a spring 11, a moving block 12, a connecting block 13, a fixing plate 14, a first motor 15, an eccentric wheel 16, a cylinder 17, and a second motor 18. In operation, the specific details are as follows... Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a feeding pipe 3 is fixedly installed on the upper left side of the box 1. A second motor 18 is fixedly installed on the lower front side of the feeding pipe 3. A connecting rod 9 is connected to the output end of the second motor 18. A partition plate 10 is fixedly installed on the outside of the connecting rod 9. Pet food is placed on the upper side of the feeding pipe 3 using a tool, so that the pet food falls into the inside of the feeding pipe 3. Under the action of gravity, the pet food falls between the partition plates 10 set on the outside of the connecting rod 9. The partition plate 10 is activated, so that the connecting rod 9 connected to the output end of the partition plate 10 rotates on the lower side of the inside of the feeding pipe 3 under the driving action of the partition plate 10. Under the action of the rotation of the connecting rod 9, the connecting rod 9 drives the partition plate 10 to rotate, so that the pet food inside the partition plate 10 rotates to the lower side of the inside of the feeding pipe 3. Under the action of gravity, the pet food falls into the inside of the box 1 through the hole structure opened on the lower side of the feeding pipe 3, so that the pet food falls onto the upper side of the sieve plate 4, which facilitates the quantitative feeding of pet food.

[0032] Specific examples Figure 1 , Figure 2 and Figure 5 As shown, a fixed plate 14 is fixedly installed on the upper left side of the box 1. A first motor 15 is set on the upper left side of the fixed plate 14. An eccentric wheel 16 is connected to the output end of the first motor 15. A connecting block 13 is movably installed on the upper side of the eccentric wheel 16. Through a fixed connecting plate 6 fixedly installed on the upper side of the middle of the box 1, the pet food can be prevented from being too high, thus affecting the screening of the pet food. The first motor 15 installed on the left side of the fixed plate 14 is started, so that the eccentric wheel 16 connected to the output end of the first motor 15 rotates under the driving action of the first motor 15. Under the action of the rotation of the eccentric wheel 16, the eccentric wheel 16 drives the connecting block 13 to move up and down reciprocally. Then, under the action of the up and down reciprocating movement of the connecting block 13, the connecting block 13 drives the moving block 12 to slide up and down on the upper side of the inside of the box 1, so that the moving block 12... The downward telescopic sliding action causes the moving block 12 to drive the spring 11 to extend and retract, thereby causing the sieve plate 4 to vibrate up and down inside the box 1 under the reciprocating action of the connecting block 13. Then, through the mounting rod 7, the lower sieve plate 4 vibrates up and down, causing the sieve plate 4 set on the upper side inside the box 1 to screen the largest pet food, so that the screened pet food falls onto the sieve plate 4 located in the middle inside the box 1, which in turn screens the medium-sized pet food, and the screened pet food falls onto the sieve plate 4 located in the lower side inside the box 1, which in turn screens the small-sized pet food, and finally, the smallest size pet food falls into the collection frame 2, ensuring a good grading and screening effect for pet food.

[0033] Specific examples Figure 1 and Figure 3 As shown, the pet food is screened by the sieve plate 4 and pushed onto the inside of the discharge pipe 5 through the discharge pipe 5 fixed on the outside of the box 1, the cylinder 17 fixedly installed on the outside of the middle of the box 1, and the baffle plate 8 fixedly installed on the lower side of the cylinder 17. The baffle plate 8 installed inside the discharge pipe 5 can prevent pet food of various sizes from being discharged through the discharge pipe 5 located on the upper side of the box 1 without being screened. The cylinder 17 installed on the outside of the middle of the box 1 is activated, so that the cylinder 17 drives the baffle plate 8 to move upward in the middle of the discharge pipe 5. The baffle plate 8 separates inside the discharge pipe 5 under the action of upward movement, and the pet food is discharged through the discharge pipe 5 under the action of gravity. Then, the collection frame 2 is manually pulled, so that the collection frame 2 slides to the left inside the lower side of the box 1 under the action of pulling, so that the collection frame 2 separates inside the lower side of the box 1, which facilitates the discharge of the screened pet food.
