Description

Technical Field

[0001] This utility model relates to a printing roller for packaging printing, belonging to the technical field of packaging printing equipment. Background Technology

[0002] Printing rollers, also called steel rollers, are solid rollers with shafts. They are generally used for printing plates. The surface of the roller is copper-plated, and the pattern is engraved by a gravure electronic engraving machine. Then, a layer of chromium is plated on it. They are commonly used for printing on plastic packaging bags.

[0003] Although existing printing rollers can perform routine printing on packaging bags, the printing patterns on the rollers will wear down over time, requiring replacement of the worn rollers. However, most existing printing rollers are single units, so the entire roller must be replaced when needed, making it inconvenient to replace worn parts individually. Unworn parts cannot be reused, resulting in a waste of resources and higher usage and manufacturing costs for printing rollers. Utility Model Content

[0009] The supporting inner shaft is laterally disposed in the second inner hole and extends to the first inner hole at both ends, and the outer diameter of the supporting inner shaft is matched with the first inner hole and the second inner hole respectively.

[0010] Furthermore, the first inner hole has a blind groove for preventing rotation, and the second inner hole has a transversely extending through groove for preventing rotation.

[0011] The outer circumferential surface of the inner support shaft is provided with an anti-rotation strip extending along its axis.

[0012] The dimensions of the anti-rotation strip are respectively matched with the anti-rotation through groove and the anti-rotation blind groove;

[0013] The body of the anti-rotation strip penetrates through the anti-rotation through groove and extends to both sides in the axial direction into the anti-rotation blind groove.

[0014] Furthermore, the plug-in rod body is provided with a plurality of lower connecting holes evenly distributed along the circumferential direction of the axis, and the lower connecting holes are provided with internal threads;

[0015] The connecting area is provided with a plurality of corresponding upper connecting holes evenly distributed along the circumferential direction of the axis;

[0018] The beneficial effects of this utility model are as follows:

[0019] This solution enables the disassembly of the outer printing roller. When the texture on the outer printing roller is worn and needs to be replaced, it is not necessary to disassemble and replace the entire printing roller. The unworn parts can continue to be used, effectively improving the utilization rate of printing roller resources and reducing the cost of printing roller use and manufacturing.
