Description

Technical Field

[0001] This utility model relates to the field of inkjet printing device technology, specifically to an inkjet printing device for conveying food packaging boxes. Background Technology

[0002] In food packaging production lines, the coding process on packaging boxes is a crucial step, used to identify product information, production date, batch number, and other details. To ensure the accuracy and clarity of the coding, the packaging box's position usually needs to be precisely positioned before coding. Current technology often uses positioning baffles to limit and correct the packaging boxes on the conveyor line, ensuring they align with the coding machine when they move beneath it, thus guaranteeing consistent coding position.

[0003] However, existing positioning baffles only have simple mechanical positioning functions and cannot clean dust or impurities from the surface of packaging boxes. In actual production processes, dust, debris, and other contaminants easily adhere to the surface of packaging boxes during transportation, stacking, or storage. If coding is applied directly, the ink cannot adhere firmly to the surface of the packaging box, resulting in blurred, detached, or incomplete coding, affecting the readability and aesthetics of product identification, and may even lead to quality disputes due to unclear information.

[0004] In addition, some production lines add independent cleaning devices (such as brushes, air blowers, etc.) before coding, but such solutions require additional equipment costs and installation space. Therefore, there is an urgent need for a device that integrates positioning and cleaning functions, which can accurately position the packaging box while effectively cleaning the dust on its surface, thereby improving coding quality and production efficiency. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a food packaging box conveying coding device, which achieves the goal of solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a food packaging box conveying coding device, including a coding machine, a first conveyor used in conjunction with the coding machine, a coding device mounted on the first conveyor for coding, and a second conveyor mounted on one side of the first conveyor. The second conveyor is equipped with a positioning baffle for positioning the packaging box. The positioning baffle is equipped with a cleaning component for cleaning the coding position on the packaging box. The cleaning component includes: a cleaning head, bristles mounted in a groove inside the cleaning head, and a pipe connected to the groove.

[0007] As a further improvement to the above technical solution:

[0008] The positioning baffle includes: a baffle fixedly connected to the cleaning head, and an adjustment bracket set on the cleaning head for adjusting the position of the cleaning head.

[0009] The adjusting frame includes: a connecting rod 1 fixedly connected to the cleaning head, a sleeve 1 sleeved on the connecting rod 1, a connecting rod 2 fixedly connected to the bottom of the sleeve 1, and a sleeve 2 sleeved on the outside of the connecting rod 2 and fixedly connected to the conveyor 2; both the sleeve 1 and the sleeve 2 are threadedly connected to clamping blocks inside.

[0010] Both connecting rod one and connecting rod two are hollow rods. The sleeve one has a slot that communicates with the interior of connecting rod two, and the connecting rod one has a through slot.

[0011] The height of the bristles at the tip is lower than the height of the bottom edge of the baffle, or the height of the bristles at the bottom is higher than the height of the top edge of the baffle.

[0012] One end of the baffle is provided with an inclined portion.

[0013] The baffle is fitted with a protective cover.

[0014] The beneficial effects of this utility model embodiment are as follows:

[0015] When the packaging box moves on conveyor two, the positioning baffles position the packaging box so that it aligns with the inkjet printer when it reaches it. As the packaging box moves between the positioning baffles, the cleaning components on the positioning baffles clean the packaging box. When the packaging box reaches the cleaning head, the brushes clean the inkjet area of ​​the packaging box, and the cleaned debris is discharged through a pipe. This achieves the goal of cleaning the inkjet area of ​​the packaging box simultaneously with positioning it by the positioning baffles. Attached Figure Description

[0024] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0025] See Figures 1 to 4 This utility model discloses a food packaging box conveying coding device, including a coding machine 1, a conveyor 2 used in conjunction with the coding machine 1, a coding device 3 set on the conveyor 2 for coding, a conveyor 4 set on the side of the conveyor 2, and a positioning baffle 5 set on the conveyor 4 for positioning the packaging box.

[0026] The positioning baffle 5 is equipped with a cleaning component 51 for cleaning the inkjet printing position on the packaging box;

[0027] The cleaning component 51 includes: a cleaning head 511, bristles 512 fixedly connected in a groove inside the cleaning head 511, and a pipe 513 connected to the groove; the pipe 513 is connected to a negative pressure pump, so that negative pressure is generated inside the pipe 513.

[0028] In actual use, the packaging box enters the conveyor 2 through the conveyor 4. When the packaging box moves to the inkjet printer 3, the position of the packaging box is sensed by the sensing device on the inkjet printer 1, and then the inkjet printer 3 prints the code on the packaging box.

[0029] When the packaging box moves on the second conveyor 4, the positioning baffle 5 positions the packaging box so that it aligns with the inkjet printer 3 when it moves to the position of the inkjet printer 3. When the packaging box moves between the positioning baffles 5, the cleaning component 51 on the positioning baffle 5 cleans the packaging box. When the packaging box moves to the cleaning head 511, the brush 512 cleans the inkjet printing position of the packaging box, and the cleaned debris is discharged through the pipe 513. This achieves the purpose of cleaning the inkjet printing position of the packaging box simultaneously when the positioning baffle 5 positions the packaging box.

[0030] As a further explanation of this application:

[0031] The positioning baffle 5 includes: a baffle 52 fixedly connected to the cleaning head 511, and an adjustment bracket 53 provided on the cleaning head 511 for adjusting the position of the cleaning head 511;

[0032] The position and height of the cleaning head 511 are adjusted by adjusting the frame 53 so that the cleaning head 511 can be aligned with the coding position of the packaging box; while adjusting the height of the cleaning head 511 by adjusting the frame 53, the height of the baffle 52 is adjusted simultaneously.

[0033] As a further explanation of this application:

[0034] The adjusting frame 53 includes: a connecting rod 531 fixedly connected to the cleaning head 511, a sleeve 532 sleeved on the connecting rod 531, a connecting rod 533 fixedly connected to the bottom of the sleeve 532, and a sleeve 534 sleeved on the outside of the connecting rod 533 and fixedly connected to the conveyor 4; both the sleeve 532 and the sleeve 534 are threaded with clamping blocks 535; the connecting rod 531 inside the sleeve 532 is clamped by the clamping blocks 535, and the connecting rod 533 inside the sleeve 534 is clamped by the clamping blocks 535.

[0035] Connecting rod 531 can move inside sleeve 532 to adjust the distance between the two cleaning heads 511, i.e. the two baffles 52. Connecting rod 533 can move inside sleeve 534 to adjust the height of the cleaning head 511, i.e. the baffle 52.

[0036] As a further explanation of this application:

[0037] Both connecting rod 1 (531) and connecting rod 2 (533) are hollow rods. Sleeve 1 (532) has a slot 536 that communicates with the interior of connecting rod 2 (533). Connecting rod 1 (531) has a through slot 537. By setting the slot 536 and the through slot 537, the interiors of connecting rod 1 (531) and connecting rod 2 (533) are connected. Connecting rod 1 (531) and connecting rod 2 (533) are used to store pipe 513, which not only protects pipe 513, but also avoids the problem of pipe 513 being exposed and causing messy wiring.

[0038] As a further explanation of this application:

[0039] The height of the top of the bristles 512 is lower than the bottom edge of the baffle 52, or the height of the bottom of the bristles 512 is higher than the top edge of the baffle 52, so that the working surface of the bristles 512 does not overlap with the baffle 52. This ensures that after the bristles 512 clean the coding position of the packaging box, the cleaned coding position will no longer contact the baffle 52, preventing debris on the baffle 52 from adhering to the cleaned coding position.

[0040] As a further explanation of this application:

[0041] An inclined portion 6 is provided at one end of the baffle 52, which forms an opening at one end of the baffle 52, making it easier for the packaging box to enter between the baffles 52.

[0042] As a further explanation of this application:

[0043] A protective sleeve 7 is fitted onto the baffle 52. The protective sleeve 7 is made of a smooth, wear-resistant material. When the packaging box is positioned by the metal baffle 52, frequent friction between the two, coupled with the high hardness of the baffle 52, can easily scratch the surface of the packaging box. Therefore, a replaceable protective sleeve 7 is installed on the baffle 52. This effectively reduces friction damage to the packaging box and allows for easy replacement after the protective sleeve 7 wears out, thereby extending the service life of the baffle 52 and ensuring the integrity of the packaging box.
