Description

Technical Field

[0001] The present invention relates to the technical field of two-dimensional code spraying, and specifically to a device for improving the spraying accuracy of two-dimensional codes. Background Art

[0002] When the existing two-dimensional codes are sprayed, the two-dimensional codes are sprayed on the release film, and the release film is compounded on the material tape. In the actual process, since the release film is set in a roll, there will be an offset in the width direction during the processes of slitting, handling, and feeding. Therefore, in the prior art, after the release film is compounded on the material tape, the inkjet printing device sprays the two-dimensional code onto the surface of the release film. However, in the prior art, the nozzle of the inkjet printing device is fixed on the slitting machine and cannot move. The release film is on the unwinding shaft and is directly compounded with the material tape after unwinding. Therefore, only the neatness of the self-winding of the release film and the accuracy of slitting can be relied on to ensure the spraying accuracy of the two-dimensional code. In the actual process, there will be a deviation in the width position where the release film is compounded with the material tape, which will cause the two-dimensional code to be offset and set in different width areas of the release film, and further cause the actually produced two-dimensional code and the release film to be not in the same width direction, resulting in a difference in width spraying of the produced product and not meeting the requirements for the spraying accuracy of the two-dimensional code. Summary of the Invention

[0003] In view of the above problems, the present invention provides a device for improving the spraying accuracy of two-dimensional codes, which enables the output width position of the release film and the accuracy of compounding with the material tape to be high, ensures that the inkjet code sprayed by the spraying device corresponds to the same width position of the release film, and ensures the spraying accuracy of the two-dimensional code.

[0005] An installation base, the width of the installation base covering the feeding width area of the release film;

[0006] A deviation rectifying platform;

[0008] One side of the installation base is fixedly provided with an installation connection frame, and the installation connection frame is used for being fixedly arranged on the installation frame of the production line;

[0009] One side of the installation base is also provided with an upward convex nozzle installation bracket, the top of the nozzle installation bracket is provided with a nozzle fixing device, and the inkjet printer nozzle is fixedly arranged in the nozzle fixing device and the inkjet printer nozzle is arranged upward;

[0010] The installation base is arranged between two lower conveying rollers, and the installation base is arranged at the lower position of the material tape compounding roller;

[0013] A deviation rectifying probe is arranged on the second end face of the mounting base. The gap of the deviation rectifying probe is used for the release film to pass through. When the release film contacts the deviation rectifying probe, the vertical driving mechanism moves up and down to ensure that the release film passes through the gap of the deviation rectifying probe in a straight line;

[0014] An output roller is arranged directly below the deviation rectifying probe, and the output roller guides the release film to the lower conveying roller at the output end;

[0015] The inkjet printer nozzle is arranged facing the lower surface after the release film and the tape are compounded.

[0016] Its further features are as follows:

[0017] An inlet guiding roller is arranged at the upper inlet end of the horizontal platform, and an outlet guiding roller is arranged at the upper outlet end;

[0018] A material breakage detection probe is arranged on the mounting base corresponding to the conveying area of the shock-absorbing and guiding roller group. After detecting material breakage, the machine immediately stops operating;

[0019] The shock-absorbing and guiding roller group includes an upper first inlet shock-absorbing roller and a lower second outlet shock-absorbing roller, which enable the release film to pass through the upper first inlet shock-absorbing roller and then pass through the lower second outlet shock-absorbing roller and turn to be connected to the upper inlet guiding roller;

[0020] The upper first inlet shock-absorbing roller and the lower second outlet shock-absorbing roller are connected to the corresponding side parts of the mounting base through the first side connecting plates on both sides;

[0023] Reinforcing ribs are arranged at the bottom of the installation connecting frame to ensure the stability and reliability of the whole structure;

[0024] The nozzle fixing device is connected to the nozzle mounting bracket through a rotating screw. The rotating screw rotates to drive the angle adjustment of the nozzle fixing device to ensure fine adjustment of the angle direction of the inkjet printer nozzle;

[0025] The bottom of the mounting base is provided with a downwardly convex pipe buckle, and the bottom of the inkjet printer nozzle is provided with a pipe, and the pipe is connected to the inkjet printer main unit below after being clamped by the pipe buckle.

[0026] After adopting the above technical solution, the positions of the material tape and the inkjet printer nozzle are fixed. The release film is fed into the rectifying platform through the shock-absorbing guide roller group. When the release film touches the rectifying probe, the vertical lifting mechanism acts to make the release film pass through the gap of the rectifying probe in a straight line direction, ensuring that the width position of the finally output release film relative to the material tape is fixed. The inkjet printer will spray a two-dimensional code on the lower surface of the release film compounded with the material tape, which makes the output width position of the release film and the accuracy of compounding with the material tape high, ensuring that the inkjet code sprayed by the inkjet device corresponds to the same width position of the release film, and ensuring the accuracy of the two-dimensional code inkjet.
