Description

Technical Field

[0001] This utility model relates to the field of inkjet printing device technology, and in particular to a coding mechanism that can realize matrix inkjet printing. Background Technology

[0002] By spraying a matrix code onto the cardboard box, the system can quickly determine whether the matrix code was generated by the company's anti-counterfeiting system during the transportation process, thereby verifying the authenticity of the product.

[0003] A search revealed Chinese patent CN212194698U, which discloses a positioning and printing device for matrix codes on corrugated cardboard boxes. The device includes a base plate, mounting seats on the top left sides of the base plate, and bolts securing the mounting seats to the base plate. A support rod is mounted on the top of the mounting seats, and reinforcing plates are installed between the bottom left and right sides of the support rod and the mounting seats. A support plate is mounted on the right side wall of the support rod, and a reinforcing rod connects the support plate to the support rod. A hydraulic cylinder is mounted on the right side of the support plate, and a printing plate is fixedly connected to the bottom telescopic end of the hydraulic cylinder. An infrared positioning device is fixedly connected to the left side wall of the printing plate, an inkjet printhead is mounted on the bottom of the printing plate, and an ink reservoir is mounted on the top of the support plate. This patent solves the problem of poor positioning and printing of matrix codes on corrugated cardboard boxes during the printing process.

[0004] In the aforementioned existing technical solution, the position of the corrugated carton is located by an infrared positioning device, and then the height of the printing plate is adjusted by a hydraulic cylinder before printing rectangular codes. However, in actual use, the position of the corrugated carton may shift during the conveying process, causing the printing plate to be unable to be completely aligned with the predetermined printing position on the corrugated carton. In this case, even if the height of the printing plate is adjusted by a hydraulic cylinder, it cannot be guaranteed that the rectangular codes will be accurately printed at the predetermined position.

[0035] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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 protection scope of the present invention.

[0036] This utility model provides an improved coding mechanism capable of matrix printing. The technical solution of this utility model is as follows:

[0037] like Figures 1-3 As shown, a coding mechanism capable of matrix inkjet printing includes a conveyor assembly 1, which consists of a fixed frame and a conveyor belt. A printing assembly is mounted on top of the conveyor assembly 1. The printing assembly includes a mounting frame 2, an adjusting cylinder 3, a printing plate 4, and an infrared sensor 5. The mounting frame 2 is fixedly mounted on the top wall of the fixed frame on the conveyor assembly 1. The adjusting cylinder 3 is fixedly mounted on the top wall of the mounting frame 2, with its output end extending downwards through the top wall of the mounting frame 2. The printing plate 4 is fixedly mounted on the output end of the adjusting cylinder 3, and the infrared sensor 5 is fixedly mounted on the side wall of the printing plate 4. The object to be printed is conveyed into the mounting frame 2 via the conveyor assembly 1. The infrared sensor 5 senses the object being conveyed at the top of the conveyor assembly 1 and issues a command to the adjusting cylinder 3 and the printing plate 4, causing the output end of the adjusting cylinder 3 to extend downwards. When the output end of the adjusting cylinder 3 moves to a set position, the printing plate 4 prints on the surface of the object. The top of the conveying assembly 1 is equipped with a positioning assembly, which includes a clamping plate 6, a mounting plate 9, and a pressing plate 11. There are two clamping plates 6. The side walls of the two clamping plates 6 that are far apart are attached to the side walls of the mounting frame 2 that are close to each other. The mounting plate 9 is threaded onto the side wall of the output end of the adjusting cylinder 3. There are also two pressing plates 11. The two pressing plates 11 are placed on both sides of the mounting plate 9. The two pressing plates 11 are aligned with the positions of the two clamping plates 6, and the side walls of the two clamping plates 6 and the two pressing plates 11 are inclined. By threading the mounting plate 9 onto the side wall of the adjusting cylinder 3, the mounting plate 9 can move synchronously with the output end of the adjusting cylinder 3. The pressing plate 11 at the bottom of the mounting plate 9 presses the side wall of the clamping plate 6, causing the two clamping plates 6 to move to the side that is close to each other, clamping the object at the top of the conveying assembly 1. By fixing the position of the object, the accurate position of the printing plate 4 is ensured.

[0038] like Figures 1-3As shown, in one embodiment, to increase the spraying range of the printing plate 4, an adjustment assembly is provided inside the mounting frame 2. The adjustment assembly includes two adjusting screws 10 and two positioning bearings 12. Both adjusting screws 10 are threaded onto the side wall of the mounting plate 9, and the two positioning bearings 12 are respectively fixedly installed on the top wall of the two extrusion plates 11. The bottom ends of the two adjusting screws 10 are respectively fixedly installed on the inner side wall of the two positioning bearings 12. By rotating the two adjusting screws 10, the height of the two extrusion plates 11 is adjusted, allowing the two extrusion plates 11 to be at different heights. When the adjusting cylinder 3... When the output end extends downwards, the two extrusion plates 11 can push the two clamping plates 6 to move different distances respectively, so that the printing plate 4 can print on the surface of the object near the side; the mounting frame 2 is provided with a reset assembly, which includes a sliding plate 7 and a reset spring 8. There are two sliding plates 7 and two reset springs 8. The two sliding plates 7 are slidably mounted on the side wall of the mounting frame 2. The ends of the two sliding plates 7 that are close to each other are respectively fixedly mounted on the side wall of the clamping plate 6. The two ends of the reset spring 8 are respectively fixedly mounted on the sliding plates 7 and the side wall of the mounting frame 2 that are close to each other; the two sliding plates 7 enable the two clamping plates 6 to slide stably, and the reset spring 8 is used to achieve this. The elasticity of the spring allows the return spring 8 to push the two clamping plates 6 to move away from each other, facilitating the reset of the clamping plates 6. An interception assembly is fixedly installed on the side walls of both clamping plates 6. The interception assembly includes an interception rod 13, a positioning block 14, a fixing block 15, and a fixing spring rod 16. The interception rod 13 is L-shaped and slidably installed inside adjacent clamping plates 6. The side walls of the interception rod 13 are serrated. The fixing block 15 is fixedly installed on the side wall of the clamping plate 6. The fixing spring rod 16 is fixedly installed on the side wall of the fixing block 15 near the interception rod 13. The positioning block 14 is fixedly installed at one end of the fixing spring rod 16. The end of the intercepting rod 13 away from the fixed spring rod 16 is locked inside the serrated groove on the intercepting rod 13. By setting an intercepting component on the side wall of the clamping plate 6, when the two extrusion plates 11 push the two clamping plates 6 to move to the same side, the protruding end of the intercepting rod 13 can intercept the object, so that the object will not move synchronously with the conveyor belt, making it convenient for the clamping plate 6 to clamp the object. By sliding the intercepting rod 13, the length of the intercepting rod 13 can be adjusted. The position of the intercepting rod 13 is limited by the positioning block 14 to ensure the stability of the position of the intercepting rod 13. It is convenient to adjust the length of the intercepting rod 13 according to the position to be printed on the surface of the object, thereby improving the accuracy of the printing position.

[0039] The specific working method is as follows: The object to be printed is conveyed into the mounting frame 2 through the conveying component 1. The infrared sensor 5 senses the item conveyed on the top of the conveying component 1 and issues a command to adjust the oil cylinder 3 and the printing plate 4 to work, so that the output end of the adjusting oil cylinder 3 extends downward. The mounting plate 9 moves synchronously with the output end of the adjusting oil cylinder 3, so that the extrusion plate 11 at the bottom of the mounting plate 9 presses the side wall of the clamping plate 6, so that the two clamping plates 6 move to the same side and clamp the object at the top of the conveying component 1. By fixing the position of the object, the printing plate 4 is ensured to spray the pattern accurately. When the output end of the adjusting oil cylinder 3 moves to the set position, the printing plate 4 sprays the pattern on the surface of the object.

Matters not covered in this utility model are common knowledge to those skilled in the art.
