AI Technical Summary

Technical Problem

In existing offset printing positioning and clamping devices for cigarette packaging, ink easily spills onto the printing roller head during the printing process, leading to bearing wear, reduced positioning accuracy, and affecting the quality of printed products and the lifespan of the equipment. Furthermore, frequent manual cleaning is required, reducing production efficiency.

Method used

It adopts a clamping mechanism with a protective structure and an automatic cleaning mechanism. The combination of T-shaped sleeve and T-shaped top shaft prevents ink spillage, and the movable cleaning mechanism and 360° annular air jet nozzle realize automatic cleaning and air drying, ensuring that the entire length of the printing roller is clean without dead angles.

Benefits of technology

It effectively prevents ink from wearing down bearings, reduces equipment maintenance costs, increases equipment uptime, reduces manual labor intensity, and ensures the quality of printed materials and the cleanliness of the production environment.

Abstract

The invention relates to the technical field of printing equipment, and discloses a rapid positioning and clamping device for offset printing of cigarette packages. The device comprises a fixing frame, and two clamping mechanisms and a cleaning mechanism used for automatically flushing the clamping mechanisms are arranged on the fixing frame; the clamping mechanism comprises a T-shaped sleeve rotationally connected with the fixing frame, a T-shaped jacking shaft capable of stretching and retracting in the axial direction is arranged in the T-shaped sleeve, the printing roller is clamped and limited through stretching and retracting, and a corrugated pipe used for preventing ink from invading is arranged between the T-shaped sleeve and the T-shaped jacking shaft. The cleaning mechanism comprises a groove-shaped ring arranged outside the corrugated pipe in a covering mode, and an annular spray pipe connected with external water supply equipment and an absorption cavity connected with external water pumping equipment are arranged in the groove-shaped ring. Through physical partition and automatic cleaning, the problem of ink pollution is effectively solved, the service life of equipment is prolonged, and the production efficiency is improved.
