Adjusting device for laser interstice of laser pad printing machine

Abstract

The invention provides an adjusting device for a laser interstice of a laser pad printing machine, belongs to the technical field of machinery and solves the technical problems that in the prior art, the laser interstice of a laser pattern printing device can not be adjusted, the device can not adapt to the laser operation of packaging film with different types of thickness, and the universality is poor. According to the adjusting mechanism for the laser interstice of the laser pad printing machine, a laser roller and a press roller are connected to a stand of the laser pad printing machine, the laser interstice is located between the laser roller and the press roller, the adjusting mechanism comprises two lock plates, a connecting rod, locking pieces and springs, the two ends of the press roller are connected to the inner sides of the corresponding lock plates respectively, the locking pieces and the springs are connected to the stand, under the elastic effect of the springs, the locking pieces can abut against the outer sides of the lock plates correspondingly, the lock plates are enabled to be located on the stand, the connecting rod is arranged horizontally, and the two ends of the connecting rod are fixedly connected with the upper ends of the corresponding lock plates respectively. The adjusting mechanism for the laser interstice of the laser pad printing machine has the advantages of being convenient to adjust and great in universality.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an adjustment device, in particular to an adjustment device for a laser gap in a laser pad printing machine. Background technique [0002] With the development of society, modern printing technology also develops, but good technology is also used by some unscrupulous manufacturers to embezzle and imitate the logo of goods. In order to prevent their product logo from being stolen, the manufacturer needs to laser the manufacturer's logo on the outer packaging of the product through a laser pad printing machine. Because there are various types of packaging materials, it is necessary to carry out laser treatment on packaging materials of different thicknesses, so the laser gap between the laser roller and the pressure roller of the laser pad printing machine needs to be adjusted frequently, and the operation is complicated. [0003] After searching, for example, Chinese patent liter...

AI Technical Summary

Problems solved by technology

[0004] Although the laser pattern printing device disclosed in this patent can directly print laser anti-counterfeiting patterns on the UV varnish layer, improve production efficiency, reduce costs and enhance anti-counterfeiting, the laser gap in the laser pattern printing device cannot be adjusted, and cannot adapt to different The laser operation of the thick packaging film has poor versatility. Therefore, it is necessary to design a laser gap adjustment device in the laser pad printing machine.
