Description

Technical Field

[0001] This utility model relates to the field of inkjet printers, specifically a traceability inkjet printer for food safety. Background Technology

[0002] To achieve traceability and tracking of the entire process from production to consumption, thereby ensuring food safety, it is necessary to assign a unique identifier to the surface of food packaging, such as a QR code, barcode, or digital batch number. The most common method is to use an inkjet printer to laser-engrav barcodes and production dates on the surface of food packaging to facilitate food traceability.

[0003] Currently, when printing codes on food packaging, large-scale printing on production lines typically involves using conveyor belts to transport the food packaging. However, in discrete logistics systems, individual packages need to be printed during transport. During the printing process, if the packaging is disturbed or placed unevenly, the printed code may be misaligned, blurry, or missing, thus affecting the readability of traceability information. Therefore, this paper proposes a traceability inkjet printer for food safety to address these issues. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and avoid the problem of unreadable coding information, this utility model proposes a traceability coding machine for food safety.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a traceability inkjet printer for food safety, including a base, a laser inkjet printer fixedly installed on the rear side of the top of the base, a placement groove opened in the middle of the top of the base, and driving components are provided on both the front and rear sides of the base located in the placement groove, and a limiting component is provided inside the driving component.

[0006] The limiting component includes a cavity plate disposed inside the placement slot. A vacuum pump is fixedly connected to the rear end of the cavity plate. A damping block is fixedly connected to one end of the cavity plate near the center of the placement slot. A hollow rod is slidably connected inside the cavity plate. A suction cup is fixedly connected to one end of the hollow rod away from the cavity plate. A valve is disposed inside the hollow rod. A protrusion is fixedly connected to one end of the hollow rod near the inside of the cavity plate. A buffer spring is disposed on the surface of the hollow rod near the inside of the cavity plate.

[0007] Preferably, the output end of the vacuum pump is connected to the interior of the cavity plate, and the cavity plate, hollow rod and suction cup are connected, so that the air pressure inside the suction cup can be controlled by driving the vacuum pump.

[0008] Preferably, the hollow rod extends through both the inner and outer sides of the cavity plate, and the hollow rod is slidably connected to the surface of the damping block. The damping block dampens the movement of the hollow rod, preventing the hollow rod from swaying.

[0009] Preferably, one end of the buffer spring is fixedly connected to the inner wall of the cavity plate, and the other end of the buffer spring is fixedly connected to the surface of the protrusion. The buffer spring allows the hollow rod to move within a small range, so as to limit the packaging of different sizes.

[0010] Preferably, the drive assembly includes two inner slots located on the front and rear sides of the base, with hollow blocks fixedly installed in the middle of each inner slot. Photoelectric sensors are fixedly connected to the proximal ends of the two hollow blocks. A rodless cylinder is fixedly connected inside the hollow block. Connecting rods are fixedly connected to the output ends on both sides of the rodless cylinder. A storage plate is fixedly connected to the end of the connecting rod away from the rodless cylinder.

[0011] Preferably, the photoelectric sensor is electrically connected to a microcontroller, which is fixedly installed on the top of the hollow block. The microcontroller is electrically connected to the rodless cylinder. When the package is placed between the two photoelectric sensors, the photoelectric sensor drives the rodless cylinder to operate through the microcontroller.

[0012] Preferably, the front and rear ends of the storage plate are fixedly connected to two rodless cylinders, and the storage plate is slidably connected inside the placement slot.

[0013] Preferably, the hollow plate is fixedly connected to the inside of the storage plate, and the end of the suction cup away from the hollow rod extends to the outside of the storage plate, and the suction cup can perform negative pressure adsorption on the packaging.

[0014] The advantages of this utility model are:

[0015] This invention involves placing the packaging inside the slot below the laser marking machine. At this time, the rodless cylinder moves automatically, driving the suction cup to move to the surface of the packaging. Then, it can drive the vacuum pump and use the suction cup to apply negative pressure to the packaging, so that the subsequent marking of the packaging will not move. This results in clear, accurate and compliant marking information, which is convenient for traceability. Attached Figure Description

[0025] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0026] This application discloses a traceability inkjet printer for food safety. (Refer to...)

A limiting component 5 is provided inside the drive component 4.

[0027] Reference Figure 2 , Figure 4 , Figure 5 and Figure 5The limiting component 5 includes a cavity plate 51 disposed inside the placement slot 3. A vacuum pump 52 is fixedly connected to the rear end of the cavity plate 51. A damping block 53 is fixedly connected to one end of the cavity plate 51 near the middle of the placement slot 3. A hollow rod 54 is slidably connected inside the cavity plate 51, passing through both the inner and outer sides of the cavity plate 51. The hollow rod 54 is slidably connected to the surface of the damping block 53, and the damping block 53 dampens the movement of the hollow rod 54 to prevent the hollow rod 54 from shaking. A suction cup 55 is fixedly connected to the end of the hollow rod 54 away from the cavity plate 51. The output end of the vacuum pump 52 and the cavity plate 51 are connected to the cavity plate 51. The cavity plate 51, hollow rod 54, and suction cup 55 are connected. The air pressure inside the suction cup 55 can be controlled by driving the vacuum pump 52. A valve 56 is installed inside the hollow rod 54. A protrusion 57 is fixedly connected to one end of the hollow rod 54 near the inside of the cavity plate 51. A buffer spring 58 is installed on the surface of the hollow rod 54 near the inside of the cavity plate 51. One end of the buffer spring 58 is fixedly connected to the inner wall of the cavity plate 51, and the other end of the buffer spring 58 is fixedly connected to the surface of the protrusion 57. The buffer spring 58 allows the hollow rod 54 to move within a small range, so as to limit the packaging of different sizes.

[0028] Reference Figures 2-4 The drive assembly 4 includes two inner grooves 41 located on the front and rear sides of the placement groove 3 on the base 1. A hollow block 42 is fixedly installed in the middle of each inner groove 41. A photoelectric sensor 43 is fixedly connected to the adjacent ends of each hollow block 42. A rodless cylinder 44 is fixedly connected inside each hollow block 42. A microcontroller is electrically connected to each photoelectric sensor 43. The microcontroller is fixedly installed on the top of the hollow block 42. The microcontroller and the rodless cylinder 44 are electrically connected. When the package is placed between the two photoelectric sensors 43, the photoelectric sensor 43... 3. The rodless cylinder 44 is driven by a microcontroller. The output ends of the rodless cylinder 44 on both sides are fixedly connected to connecting rods 45. The end of the connecting rod 45 away from the rodless cylinder 44 is fixedly connected to a storage plate 46. The front and rear ends of the storage plate 46 are fixedly connected to the two rodless cylinders 44 respectively. The storage plate 46 is slidably connected inside the placement slot 3. The hollow plate 51 is fixedly connected inside the storage plate 46. The end of the suction cup 55 away from the hollow rod 54 extends to the outside of the storage plate 46. The suction cup 55 can perform negative pressure adsorption on the packaging.

[0029] Working principle: The operator first adjusts the microcontroller according to the size of the food packaging to control the stroke of the rodless cylinder 44 within a suitable range. Then, the food packaging bag is placed in the approximate middle position inside the placement slot 3. At this time, the food packaging bag is between two photoelectric sensors 43. The photoelectric sensors 43 send this signal to the microcontroller to drive the rodless cylinder 44, so that the output end of the rodless cylinder 44 drives the connecting rod 45 to move. At this time, the two storage plates 46 move inside the placement slot 3 and gradually approach each other. After moving to the predetermined stroke, the storage plates 46 stop near the food packaging.

[0030] If the storage plate 46 moves too close to the food packaging during the movement of the storage plate 46, the packaging will press the suction cup 55 and push the hollow rod 54. Then the hollow rod 54 will stretch the buffer spring 58 and move into the cavity plate 51 to avoid the hollow rod 54 and the cavity plate 51 from making rigid contact and damaging the surface of the food packaging.

[0031] Afterwards, the operator can start the vacuum pump 52 and open the valve 56. The vacuum pump 52 will extract the gas inside the cavity plate 51. At the same time, the gas inside the suction cup 55 attached to the surface of the food packaging will also be extracted. That is, the inside of the suction cup 55 is in a negative pressure state, so that the suction cup 55 can stably adsorb the attached food packaging. Then, the laser marking machine 2 will be turned on to laser mark the surface of the food packaging.

[0032] After the coding is completed, the vacuum pump 52 is started to spray gas into the cavity plate 51, so that the pressure inside the suction cup 55 is restored to the same value as the external atmospheric pressure. At this time, the suction cup 55 no longer applies negative pressure to the food packaging. Then the coded packaging can be removed.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
