A extrusion self-adjusting device for printing machinery

Abstract

The invention discloses an extruding self-regulating device of printing machinery, which comprises a main body shell, and movable chute is arranged on the left and right sides of the inner surface of the main body shell, and the movable chute is arranged on the inner side of the main body shell in a front-back symmetrical form. The front and rear ends of the movable chute, and the inner side of the movable chute is slidably connected with a movable slider, and the movable slider is fixedly connected to the outer end of the connecting plate, and the connecting plate is provided with 1, and the middle part of the lower end of the movable bracket is respectively connected with the front and rear ends of the lifting bracket, the middle part of the lower end of the lifting bracket is fixedly installed with a lifting sliding sleeve, and the inner side of the lifting sliding sleeve is nested and connected with a lifting column. The extruding self-adjusting device of the printing machine can facilitate automatic adjustment of printing pressure in a small range, and the operation steps are simple and convenient when adjusting the printing pressure manually, which improves work efficiency, has high adjustment accuracy, and reduces production costs by adopting a labor-saving structure.

Description

technical field [0001] The invention relates to the technical field of printing machinery, in particular to an extrusion self-adjusting device for printing machinery. Background technique [0002] Printing machinery is a mechanical device that can use ink to print the desired pattern or text on paper or other substrates. Nowadays, with the development of science and technology, various new printing technologies have emerged, such as electronic printing, inkjet printing, Thermal transfer printing, etc., but the traditional printing technology that relies on printing pressure for ink transfer still dominates. [0003] However, the existing printing machinery is inconvenient to automatically adjust the printing pressure, and the operation is cumbersome and the efficiency is low when the manual adjustment is performed. Then, the ink is transferred to the substrate attached to the bottom roller through the plate roller. Therefore, adjusting the printing pressure is to adjust the...
