Description

Technical Field

[0001] This utility model relates to the field of food traceability technology, and in particular to a coding device for food traceability. Background Technology

[0002] Food is the most important thing for people, and food safety has always been a very important issue for us. Once a problem occurs with food, it is necessary to trace the source of the food during processing, packaging, storage, and transportation. Therefore, food traceability coding is very important. Through food traceability coding, companies can track the information of each batch of food from raw materials to production, packaging, and transportation. Once a problem food is discovered, the company can quickly find the source and take necessary measures to prevent the problem from escalating.

[0003] Food traceability coding devices achieve efficient and secure traceability management through dynamic encryption and blockchain technology: First, product data (such as batch, raw materials, quality inspection, etc.) is obtained from the production system and encrypted to generate a unique hash value; then, AI vision identifies the product shape and automatically adjusts the printhead parameters (height, angle, droplet size), using modular printheads (ink / laser) to accurately print encrypted QR codes or micro-dot matrix patterns on the packaging surface; after coding, the vision system detects quality in real time and optimizes parameters in a closed loop, while uploading the data hash value to the blockchain for evidence storage; after consumers scan the code, the system decrypts and verifies the blockchain record, displaying complete traceability information (production, logistics, quality inspection, etc.), achieving anti-counterfeiting and full-chain traceability.

[0004] However, existing inkjet printing devices for food traceability do not adjust or limit the product before printing the code. The product will change when it moves, affecting the actual printing effect. In addition, external dust will interfere with the printing, affecting the printing quality. The applicability of the inkjet printing device is low and it cannot handle different products. Therefore, a new inkjet printing device for food traceability is proposed to solve the above problems.

[0033] 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.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a food traceability coding device, including a support plate 1. Two connecting plates 2 are fixedly connected to one side of the support plate 1, and a support plate 3 is fixedly connected to one end of each connecting plate 2. The support plate 1, the support plate 3, and the connecting plates 2 form a stable frame to ensure the stability of the equipment during production. A conveyor belt 7 is installed between the connecting plates 2 and the support plate 3. The conveyor belt 7 is installed on the frame composed of the two support plates. A motor 9 is installed on one side of the support plate 3. The conveyor belt 7 is driven by the motor 9 to achieve smooth transportation and avoid product tilting or jamming during movement. A fixed rod 4 is fixedly connected to the top of the support plate 1. The other end of the fixed rod 4 is fixedly connected to one side of the support plate 2 3. An adjustment component is installed at the bottom of the fixed rod 4. A fixed rod 5 is fixedly connected to the top of the support plate 1. A moving component is installed in the middle of the fixed rod 5. The fixed rod 4 and the fixed rod 5 serve as the main support structure and are respectively connected to the adjustment component and the moving component to form a linkage adjustment system in the vertical and horizontal directions to adapt to the coding requirements of products of different shapes and sizes. A dust removal component is provided on one side of the support plate 2 3.

[0035] The adjustment assembly includes a second motor 14, which is mounted on one side of a second support plate 3. A bidirectional threaded rod 12 is rotatably connected to one side of a first fixed rod 4. One end of the bidirectional threaded rod 12 is fixedly connected to the output end of the second motor 14. The second motor 14 drives the bidirectional threaded rod 12 to rotate. Two moving rods 16 are threadedly connected to the outside of the bidirectional threaded rod 12. The bottom of each of the two moving rods 16 is fixedly connected to a limit plate 17, which drives the two moving rods 16 to move in opposite directions, thereby adjusting the position between the two limit plates 17. A round rod 15 is fixedly connected between the first fixed rod 4 and the second support plate 3. The two moving rods 16 are slidably connected to the outside of the round rod 15. The round rod 15 acts as a guide rail to limit the lateral displacement of the moving rods 16 and ensure the straightness of the adjustment process. The bottom of the fixed rod 4 is fixedly connected to the support block 13, and the bidirectional threaded rod 12 is rotatably connected to the middle of the support block 13. The support block 13 is embedded in the bottom of the fixed rod 4, providing a rotation fulcrum for the bidirectional threaded rod 12, enhancing structural stability. The position of the product can be quickly adjusted by adjusting the rental price, so that the product on the conveyor belt 7 is always in the middle, which is convenient for inkjet printing and improves production efficiency.

[0036] Reference Figure 1 and Figure 5 The moving component includes a rack 22, which is fixedly connected to the top of a fixed rod 5. A groove 21 is formed at the top of the fixed rod 5, and an electric push rod 23 is slidably connected inside the groove 21. A motor 25 is fixedly connected to one end of the electric push rod 23, and a gear 26 is fixedly connected to the output end of the motor 25. The gear 26 meshes with the rack 22. The moving component drives the gear 26 to mesh with the rack 22 via the motor 25, thereby achieving the lateral movement of the nozzle 27. Two fixed plates 24 are fixedly connected to the outside of the electric push rod 23. The two fixed plates 24 are located on the upper and lower sides of the groove 21, respectively, confining the electric push rod 23 inside the groove 21. The nozzle 27 is fixedly connected to the moving end of the fixed plate 24, and the height of the nozzle 27 can be adjusted by extending or retracting the electric push rod 23. Motor 25 is equipped with a motor cover 19, which is located on the upper part of slide 21. The motor cover 19 protects motor 25 from external environmental interference and extends the equipment life. A protective cover 6 is fixedly connected to the top of the fixed rod 25. The rack 22 and gear 26 are both located inside the protective cover 6. The protective cover 6 encloses the rack 22 and gear 26 to prevent external interference from causing transmission failure. When the conveyor belt 7 detects products of different sizes, the system can automatically call the preset parameters to drive motor 25 and electric push rod 23 to work together to ensure that the coding position accurately covers the product surface and avoid the blurring problem caused by angle deviation in traditional fixed inkjet printers.

[0037] Reference Figure 1 , Figure 2 and Figure 4The dust removal component includes a fixing member 10, which is fixedly connected to one side of a support plate 3. A mounting hole 18 is provided in the middle of the support plate 3, and the fixing member 10 is located inside the mounting hole 18. A fan 8 is installed inside the fixing member 10. The dust removal component uses the fan 8 to blow high-speed airflow from the mounting hole 18 to remove dust and impurities from the coding area. A mounting groove 20 is provided in the middle of the fixing member 10, and a filter plate 11 is slidably connected inside the mounting groove 20. The filter plate 11 filters the air drawn in by the fan 8. The filter plate 11 is slidably installed in the mounting groove 20 for easy periodic replacement or cleaning, ensuring dust removal efficiency. By setting up the dust removal component, particulate matter is prevented from adhering to the coding surface, causing information blurring, while also reducing the risk of nozzle 27 clogging and improving the stability of continuous equipment operation.

[0038] Working principle: First, during operation, motor 9 drives the conveyor belt 7 to move, transporting the items to be printed. When the items are transported between the two limiting plates 17, motor 14 is driven, which in turn drives the bidirectional threaded rod 12 at the output end to rotate. The bidirectional threaded rod 12 drives the two external threaded moving rods 16 to rotate. The round rod 15 restricts the movement of the two moving rods 16, allowing them to move horizontally only. This causes the limiting plates 17 at the bottom of the two moving rods 16 to move, squeezing the goods on the conveyor belt 7 and adjusting their position. This facilitates the placement of the printhead 27 for printing, improving work efficiency.

[0039] Secondly, when coding different items, the motor 25 can be driven to rotate the gear 26 at the output end. The gear 26 rotates on the rack 22 below, which in turn moves the motor 25. This moves the electric push rod 23 connected to the fixed plate 24 below the motor 25, adjusting the position of the nozzle 27 fixed at the end of the electric push rod 23, thus changing the coding position. At the same time, the electric push rod 23 can be driven to raise and lower the nozzle 27, allowing for multi-directional adjustment to accommodate objects of different sizes and improve practicality.

[0040] Finally, a fan 8 is installed inside the mounting hole 18 in the middle of the support plate 2 3. The fan 8 blows away the dust in the coding area, making the coding clearer. At the same time, a filter plate 11 is installed inside the mounting groove 20 inside the fastener 10. When the fan 8 is working, the filter plate 11 filters the dust in the air it draws in, preventing dust from being blown into the coding area, improving the quality of the coding and facilitating food traceability.

[0041] 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.
