Technical Field

[0001] This invention relates to the field of pet food testing technology, specifically to an online product quality sampling inspection device for pet food production lines. Background Technology

[0002] Pet food refers to food specifically designed and produced for pets, aiming to meet their nutritional needs at different stages of growth, health conditions, and lifestyles. There are many types of pet food, including dry food, wet food, snacks, and health supplements. Their ingredients and formulas are scientifically designed to ensure that pets can obtain sufficient nutrients such as energy, protein, fat, vitamins, and minerals.

[0003] Quality control is a crucial aspect of pet food production. To ensure the safety and nutritional value of pet food, regular random inspections of the products are necessary during the production process.

[0004] Existing sampling methods typically involve manual handheld samplers to take samples from food on the production line, which are then sent to testing equipment for analysis. However, manual sampling requires frequent intervention from operators, increasing their workload. Furthermore, the entire process from sampling to testing is time-consuming, and manual operation may introduce external contamination, affecting the hygiene and quality of the food. Therefore, this paper proposes an online product quality sampling device for pet food production lines to address these issues. Summary of the Invention

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, by Figure 1-6 This invention discloses an online product quality sampling inspection device for a pet food production line. The device includes a production line housing 1 with a continuous conveying channel for pet food production and a fixing frame 2 fixedly installed inside the production line housing 1. A sampling component 3, a visual inspection component 4, and a crushing component 5 are sequentially arranged on the outer side of the production line housing 1 along the reverse direction of the conveying process. After the pet food is sampled by the sampling component 3, it is then inspected by the visual inspection component 4. If any product is found to be substandard, the crushing component 5 crushes the pet food, thus realizing a streamlined sampling-inspection-crushing process for pet food quality control. In the measurement operation, a linear transmission assembly 6 is provided on the inner side of the fixed frame 2. A linearly movable connecting shell 7 is fixedly connected to the top of the linear transmission assembly 6. A horizontally retractable precision electronic scale 9 is installed on the outer side of the connecting shell 7 via a pushing assembly 8. The linear transmission assembly 6 can move the pet food placed under the visual inspection assembly 4 and the crushing assembly 5. The pushing assembly 8 can move the precision electronic scale 9 under the sampling assembly 3 to receive the pet food. The precision electronic scale 9 is used to weigh the sampled pet food. A baffle is fixedly connected to the top of the precision electronic scale 9 to facilitate blocking the pet food.

[0023] The sampling assembly 3 includes a sampling cylinder 31 fixedly connected to the top of the production line housing 1, a sampling frame 32 fixedly connected to the bottom of the output end of the sampling cylinder 31, a sampling frame 33, and a telescopic cylinder 34. The sampling frame 33 is rotatably connected to the bottom of the sampling frame 32 through a hinge support and is used for collecting and sampling pet food. The output end and support end of the telescopic cylinder 34 are rotatably connected to the outside of the sampling frame 33 and the sampling frame 32, respectively.

[0024] When it is necessary to sample pet food, the sampling cylinder 31 is activated to lower the sampling frame 33 at the bottom of the sampling frame 32. When the sampling frame 33 is lowered onto the production line, the pet food will enter the inner side of the sampling frame 33. Then, the telescopic cylinder 34 is activated to make the pet food fall into the inner side of the sampling frame 33. Then, the sampling frame 33 is moved up to complete the sampling operation of the pet food sample.

[0025] The visual inspection component 4 includes an inspection frame 41 fixedly installed on the outside of the production line housing 1 and an inspection camera 42 installed below the inspection frame 41. The inspection camera 42 is used to visually inspect the morphological parameters of pet food, including quantity and size specifications.

[0026] The outer shell 1 of the production line is equipped with a control panel and a storage module. The control panel is used to control the operation of the entire device, while the storage module is used to store product information.

[0027] The number and size of the pet food samples at the top of the precision electronic scale 9 can be detected by the detection camera 42. There are two methods for evaluating pet food samples: 1) Whether the pet food samples scattered on the top of the precision electronic scale 9 are of consistent size. The maximum size deviation of a single food piece shall not exceed ±15% of the standard value. When more than 10% of the samples are found to have obvious morphological differences (such as cracks, collapses, deformations and other structural defects) during sampling inspection, the batch shall be directly judged as unqualified. This can be directly judged by the detection camera 42. The cause of this problem may be a pelleting problem in the pelleting machine during the production process. Feedback can be provided and archived.

[0028] 2) When the volume size is qualified, since the density of qualified pet food is consistent, its mass size should be within a qualified range. When the pet food is found to be outside the qualified range by the precision electronic scale 9, the batch is directly judged as unqualified. Then it is moved to the crushing component 5 for crushing operation. Then the specific cause is analyzed again by the detection camera 42. The cause of this problem may be that the meat is not crushed completely, resulting in the meat pieces being too large, the raw materials are not mixed evenly (such as starch clumping), or the extrusion process is improper (temperature / pressure fluctuation > 5%). Then feedback is given and archived.

[0029] Once the issues are archived, it will be easier to make improvements to the process, making pet food production more compliant with regulations.

[0030] The crushing assembly 5 includes: a crushing frame 51, fixedly connected to the outside of the production line housing 1; a crushing cylinder 52, fixedly connected to the outside of the crushing frame 51; a connecting plate 53, fixedly connected to the bottom of the telescopic end of the crushing cylinder 52; a crushing head 54, rotatably connected to the bottom of the connecting plate 53; multiple crushing protrusions are fixedly connected below the crushing head 54 to facilitate crushing operations; and a rotating assembly 55, fixedly connected to the top of the connecting plate 53 to drive the crushing head 54 to rotate. The rotating assembly 55 includes: a drive motor 5501, fixedly connected to the outside of the connecting plate 53; a driven gear 5502, fixedly installed on the outside of the crushing head 54; and a drive wheel 5503, fixedly installed on the bottom of the drive end of the drive motor 5501, meshing with the driven gear 5502 to drive the crushing head 54 to rotate.

[0031] When the pet food ingredients that need to be crushed are moved below the crushing head 54, the crushing cylinder 52 is activated, which causes the crushing head 54 to move down, thereby crushing the pet food. At the same time, the drive motor 5501 is activated, and the rotation of the drive wheel 5503, in conjunction with the driven gear 5502, causes the crushing head 54 to rotate, which makes the pet food crushed more clearly, facilitating subsequent inspection operations. In addition, the outer side of the crushing head 54 is coated with an anti-stick coating, which can effectively prevent pet food from sticking to the surface of the crushing head 54.

[0032] The linear transmission assembly 6 includes a transmission threaded rod 61 rotatably connected to the inner side of the fixed frame 2, a movable plate 62 threadedly connected to the outer side of the transmission threaded rod 61, and a power assembly 63 that drives the transmission threaded rod 61 to rotate. The outer side of the movable plate 62 is fixedly connected to the outer side of the connecting shell 7. There are two transmission threaded rods 61, which are symmetrically distributed on the inner side of the fixed frame 2.

[0033] The power assembly 63 includes a power worm gear 6301 fixedly connected to the outside of the transmission threaded rod 61, a power motor 6302 fixedly installed on the outside of the fixed frame 2, and a power worm 6303 fixedly connected to the outside of the output end of the power motor 6302. The power worm gear 6301 and the power worm 6303 mesh with each other on the outside, and the outside of the power worm 6303 is rotatably connected to the inside of the fixed frame 2.

[0034] Starting the power motor 6302 causes the power worm gear 6303 to rotate, which in turn drives the transmission threaded rod 61 to rotate via the power worm wheel 6301. This allows the pet food raw materials above the moving plate 62 to move left and right, facilitating testing operations.

[0035] The pushing assembly 8 includes a pushing cylinder 81, a pushing plate 82, and a limiting slider 83. The pushing cylinder 81 is fixedly installed on the outside of the connecting shell 7, and its telescopic end is fixedly connected to the pushing plate 82. The limiting slider 83 is installed on the bottom end of the pushing plate 82 and is slidably connected to the inside of the connecting shell 7.

[0036] The push component 8 can move the precision electronic scale 9 below the sampling frame 33 for convenient sampling operations.

[0037] Working principle: When sampling and testing of pet food is required, the sampling cylinder 31 is activated to lower the sampling frame 33 at the bottom of the sampling frame 32. When the sampling frame 33 is lowered onto the production line, the pet food will enter the inside of the sampling frame 33. Then, the telescopic cylinder 34 is activated to make the pet food fall into the inside of the sampling frame 33. Then, the sampling frame 33 is moved up, and the push cylinder 81 is activated to make the precision electronic scale 9 below the sampling frame 33. Then, the pet food sample is poured onto the top of the precision electronic scale 9. Reactivating the push cylinder 81 allows the precision electronic scale 9 to perform a retrieval operation. Through the linear transmission assembly 6, the precision electronic scale 9 is moved directly below the detection camera 42, and the detection camera 42, in conjunction with the precision electronic scale 9, detects whether the product is qualified. When the product is defective, the precision electronic scale 9 is moved below the crushing head 54, and the crushing cylinder 52 is activated to make the crushing head 54 move down, so that the pet food can be crushed. At the same time, the drive motor 5501 is activated, and the rotation of the drive wheel 5503 and the driven gear 5502 can make the crushing head 54 rotate, so that the pet food can be crushed more clearly. The crushed pet food is then moved under the detection camera 42 for photographic recording. At the same time, the entire production line stops production to investigate the cause before resuming production.

[0038] Example 2, by Figure 2 Give, The system also includes a cleaning component 10 and a collection component 11. The cleaning component 10 is fixedly installed on the outside of the production line housing 1 and is used to clean the pet food on the surface of the precision electronic scale 9. The collection component 11 is fixedly connected to the outside of the push component 8 and is used to collect the cleaned pet food.

[0039] The cleaning assembly 10 includes a cleaning frame 101 and a cleaning head 102. The cleaning frame 101 is fixedly installed on the outside of the production line housing 1, and the cleaning head 102 is fixedly connected to the bottom end of the cleaning frame 101. The bottom surface of the cleaning head 102 and the top surface of the precision electronic scale 9 are on the same horizontal line to ensure that the cleaning head 102 can effectively clean the surface of the precision electronic scale 9.

[0040] When the pet food sample moves under the cleaning head 102, it will be cleaned by the cleaning head 102.

[0041] The collection component 11 includes a collection rack 111 and a collection box 112. The collection rack 111 is fixedly installed on the outside of the push component 8, and the collection box 112 is embedded in the top of the collection rack 111 and is located directly below the precision electronic scale 9. It is used to collect pet food scraps swept off the surface of the precision electronic scale 9.

[0042] During the cleaning process of the cleaning head 102, pet food ingredients will fall into the collection box 112 and be collected by the collection box 112 for convenient subsequent processing.

[0043] Working principle: After the pet food sample testing is completed, the precision electronic scale 9 will continue to move. When it moves to the outside of the cleaning head 102, the cleaning head 102 can clean the pet food sample on the surface of the precision electronic scale 9. At the same time, during the continuous movement of the precision electronic scale 9, the pet food sample on its surface will fall into the collection box 112 and be collected by the collection box 112. This will clean the pet food residue on the surface of the precision electronic scale 9, making it convenient for the next pet food raw material sampling and testing operation.
