[0001] This utility model relates to the field of food safety technology, and in particular to a food traceability and anti-counterfeiting packaging device. Background Technology

[0002] Consumers can use the food traceability system to check relevant product information, such as manufacturer, production date, source of raw materials, and processing methods. This information helps consumers better understand the quality and safety of the products, thereby protecting their legitimate rights and interests. Consumers can clearly understand the entire production process of the food they purchase, including the source of raw materials, processing technology, transportation, and storage conditions. This gives consumers more confidence in the quality and safety of the food, making them more willing to buy and consume it. Food anti-counterfeiting labels use advanced anti-counterfeiting technologies, such as fluorescent ink and anti-counterfeiting patterns, to spray and package food boxes, which can effectively prevent counterfeit and inferior products from entering the market and ensure food safety.

[0003] According to the description of a food packaging anti-counterfeiting and traceability device disclosed on the patent website (authorization announcement number: CN218430577U), it "includes: a controller, an inkjet printer, and a clamping mechanism disposed at the bottom of the controller. A telescopic rod is fixedly connected to the bottom of the controller. A fixed rod is slidably sleeved on the outer wall of the telescopic rod. A limit bolt is slidably connected through the inside of the fixed rod. A limit ring is connected to the outer wall of the limit bolt. A spring is also sleeved on the outer wall of the limit bolt. A connecting rod is vertically connected to the back of the inkjet printer."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this utility model has a problem with the inkjet printer and the clamping mechanism located at the bottom of the controller. The bottom of the controller is fixedly connected to a telescopic rod, and a fixed rod is slidably sleeved on the outer wall of the telescopic rod. A limit bolt is slidably connected through the inside of the fixed rod, and a limit ring is connected to the outer wall of the limit bolt. The limit bolt and limit ring in the prior art cannot be used for spraying on food packaging boxes of various heights in large quantities. They are only suitable for spraying on packaging boxes of a single product. When spraying anti-counterfeiting and traceability packaging on multiple food packaging boxes, it is necessary to continuously adjust the height of the inkjet printer manually. Therefore, it is necessary to improve the food traceability and anti-counterfeiting packaging device to solve the above problems. Utility Model Content

[0006] To overcome the problem that existing technologies using limit bolts and limit rings are not suitable for spraying large quantities of food packaging boxes of various heights, and are only suitable for single-product packaging spraying, and that the height of the inkjet printer needs to be constantly manually adjusted when spraying anti-counterfeiting and traceability packaging for various food packaging boxes.

[0007] The technical solution of this utility model is as follows: a food traceability and anti-counterfeiting packaging device, including a line support, a rotating wheel inside the line support, a transmission belt on the rotating wheel, anti-fall plates on both sides of the line support on both sides of the transmission belt, mounting plates connected to both sides of the line support in the length direction by screws, a pair of photoelectric sensors arrayed vertically on one side of the mounting plate, a reflector on the other side of the mounting plate corresponding to the photoelectric sensors, a pushing device behind the mounting plates in the length direction of the line support, the pushing device including a baffle hinged to the anti-fall plates, and a printing device behind the pushing device, the printing device including a nozzle suspended above the transmission belt, the nozzle being able to print patterns.

[0008] Preferably, the feeding device also includes a stud, which is inserted into the anti-fall plate and can abut against the side of the baffle away from the hinge. The surface of the baffle is coated with Teflon.

[0009] Preferably, a handwheel is coaxially provided on the side of the stud away from the baffle, and a handle is eccentrically provided on the side of the handwheel away from the stud.

[0010] Preferably, the inkjet printing device includes a gantry that spans both sides of the line support in the width direction. The gantry is provided with a first clearance position, a chute, and a second clearance position on one side of the line support in the width direction. The top of the printhead is provided with a slider corresponding to the chute, and the top of the slider is provided with a connecting block corresponding to the second clearance position.

[0011] Preferably, a fixed plate is provided on the side of the gantry top away from the first clearance position. A flange plate is installed on the side of the gantry away from the fixed plate and attached to the clearance position by screws. A motor can be installed on the side of the flange plate away from the fixed plate by screws. A lead screw is rotatably connected to the output end of the motor. The connecting block includes a threaded hole corresponding to the lead screw. The side of the lead screw away from the motor is rotatably connected inside the fixed plate.

[0012] Preferably, the gantry includes support plates on both sides, and the line support includes openings corresponding to the support plates, allowing the support plates to be inserted into the openings and moved up and down.

[0013] Preferably, the two support plates are connected to a base plate at their bottom, and an electric cylinder is installed at the bottom of the base plate.

[0014] The beneficial effects of this utility model are as follows: Compared with manually adjusting the height of the inkjet printer by using limit bolts and limit rings, this device detects the height of the food packaging box by using a photoelectric sensor and a corresponding reflector above the mounting plate. This allows the device to spray traceability codes and anti-counterfeiting patterns onto food packaging boxes of various heights, improving applicability. At the same time, the pushing device can move the food packaging box to the middle of the transmission belt, ensuring that the food packaging box is centered and preventing the inkjet printer from spraying onto the edges of the food packaging box, causing blurring and contamination of the belt. The inkjet printer can spray traceability digital codes and anti-counterfeiting patterns, making food safety more guaranteed. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5This utility model provides an embodiment of a food traceability and anti-counterfeiting packaging device, including a line support 1, a rotating wheel 13 inside the line support 1, a transmission belt 11 sleeved on the rotating wheel 13, anti-fall plates 14 on both sides of the transmission belt 11 on the line support 1, mounting plates 21 connected to both sides of the line support 1 along its length direction by screws, one mounting plate 21 having a vertical array of photoelectric sensors 22 on one side, and a reflector 23 corresponding to the photoelectric sensors 22 on the other mounting plate 21, a pushing device behind the mounting plates 21 along the length direction of the line support 1, the pushing device including a baffle 34 hinged to the anti-fall plate 14, and a printing inkjet printer behind the pushing device. The device includes a printhead 51 suspended above the drive belt 11. The printhead 51 can print patterns. The height of the food packaging box is detected by a photoelectric sensor 22 above the mounting plate 21 and a corresponding reflector 23. This allows the device to print traceability codes and anti-counterfeiting patterns on food packaging boxes of various heights, improving applicability. At the same time, the pushing device can move the food packaging box to the middle of the drive belt 11, keeping the food packaging box in the center and preventing the printhead from printing on the edges of the food packaging box, causing blurring and contamination of the belt. The printhead can print traceability digital codes and anti-counterfeiting patterns, making food safety more guaranteed. The specific model of the photoelectric sensor 22 is ES80-D08JB.

[0023] Please see Figures 1-4In this embodiment, the pushing device also includes a stud 31, which is inserted into the anti-fall plate 14. The stud 31 can abut against the side of the baffle 34 away from the hinge. The surface of the baffle 34 is coated with Teflon. The anti-fall plate 14 prevents food packaging boxes on the transmission belt 11 from accidentally contacting the line support 1 and falling off. The rotation of the stud 31 can adjust the position of the baffle 34, thereby adjusting the centering of the food packaging box. A handwheel 32 is coaxially provided on the side of the stud 31 away from the baffle 34. A handle 33 is eccentrically provided on the side of the handwheel 32 away from the stud 31. The handwheel 32 specifically discloses a manual adjustment method, so the feeding device does not need to be adjusted frequently. The stud 31 is adjusted by rotating the handwheel 32 by holding the handle 33, which reduces the equipment manufacturing cost. The inkjet printing device includes a gantry 41, which spans both sides of the line support 1 in the width direction. The gantry 41 is provided with a first clearance position 414, a slide 413 and a second clearance position 415 on one side of the line support 1 in the width direction. The top of the print head 51 is provided with a slider 52 corresponding to the slide 413. The top of the slider 52 is provided with a connecting block 53 corresponding to the second clearance position 415. By moving the nozzle 51 on the gantry 41, different sizes of anti-counterfeiting patterns can be applied, improving the flexibility of the nozzle 51 spraying. Specifically, the slider 52 slides within the groove 413. The slider 52 and the groove 413 have a dovetail groove structure, which is simple in structure and low in manufacturing cost. The nozzle 51 can be installed from the first clearance position 414, and the slider 52 can be installed from the second clearance position 415. A fixing plate 411 is provided on the top of the gantry 41 away from the first clearance position 414. A flange plate 421 is installed on the side of the gantry 41 away from the fixing plate 411, which is attached to the surface of the first clearance position 414 by screws. The flange plate 421 is away from the fixing plate 414. One side of the fixed plate 411 can be fitted with a motor 42 by screws. The output end of the motor 42 is rotatably connected to a lead screw 412. The connecting block 53 includes a threaded hole 531 corresponding to the lead screw 412. The side of the lead screw 412 away from the motor 42 is rotatably connected within the fixed plate 411. The gantry 41 and the motor 42 can be connected by a flange plate 421 to serve as a transfer. The specific connection method here is by screw connection. The rotation of the motor 42 drives the lead screw 412 to rotate, causing the nozzle 51 to move. Here, the fixed plate 411 is the fixed end on both sides of the lead screw 412, and the connecting block 53 is the moving end on the lead screw 412.

[0024] Please see Figures 2-5In this embodiment, the gantry 41 includes support plates 416 on both sides, and the line support 1 includes an opening 15 corresponding to the support plate 416. The support plate 416 can be inserted into the opening 15 and moved up and down. By moving the support plate 416 up and down in the opening 15, the height of the gantry 41 can be adjusted. The opening 15 of the line support 1 can limit the support plate 416. The bottom of the two support plates 416 is provided with a connected base plate 43. The bottom of the base plate 43 is provided with an electric cylinder 44. The printing height of the nozzle 51 can be precisely adjusted by the electric cylinder 44 at the bottom of the base plate 43 to face food packaging boxes of different heights.

[0025] During operation, the sealed food packaging box is pushed onto the drive belt 11. The photoelectric sensor 22 on the mounting plate 21 determines the height of the food packaging box, and the speed of the drive belt 11 determines the distance between the food packaging boxes. The higher the food packaging box, the more photoelectric sensors 22 and reflectors 23 can be blocked. The photoelectric sensors 22 and reflectors 23 are existing technologies, and their working principle will not be described in detail here. Subsequently, the food packaging box moves to the pushing device to center its position and prevent the inkjet printer from printing on the edges of the food packaging box. The pushing device is manually adjusted by the operator holding the handle 33 and turning the handwheel. 32 then controls the stud 31 to move towards or away from the middle of the transmission belt 11. The baffle 34 is connected to the anti-fall plate 14 via a hinge on the side facing the mounting plate 21. When the food packaging box moves to the bottom of the inkjet printing device, the nozzle 51 can move to the position to be printed through the movement of the lead screw 412 and the electric cylinder 44 to print the traceability number on the food packaging box. At the same time, anti-counterfeiting patterns are printed to complete the final packaging step of the food packaging box. Customers who purchase this product can enter the traceability number code through a mobile phone program to check the origin of the food and identify the authenticity of the product by comparing it with the standard pattern on the mobile phone program. The specific model of the photoelectric 22 is ES80-D08JB.

[0026] Through the above steps, the photoelectric sensor 22 above the mounting plate 21 and the corresponding reflector 23 detect the height of the food packaging box, enabling the device to spray traceability codes and anti-counterfeiting patterns on food packaging boxes of various heights, improving applicability. At the same time, the pushing device can move the food packaging box to the middle position of the transmission belt 11, keeping the food packaging box in the center and preventing the inkjet printer from spraying on the edge of the food packaging box, causing blurring and contamination of the belt. The inkjet printer can spray traceability digital codes and anti-counterfeiting patterns, solving the problem that the existing technology using limit bolts and limit rings is not suitable for spraying large quantities of food packaging boxes of various heights, and is only suitable for single-product packaging spraying. When dealing with anti-counterfeiting and traceability spraying packaging of various food packaging boxes, the height of the inkjet printer needs to be constantly manually adjusted.
