Automatic pushing device for stencil of printing machine

Abstract

The invention discloses an automatic pushing device for a stencil of a printing machine. The automatic pushing device structurally comprises a stencil case, a control panel, a stencil outlet, a conveying table, a pressure sensor, a retractable pushing mechanism, lifting frames, lifting gears, a supporting hollow rod, a lifting toothed rail, a sliding seat, sliding rollers, a base, a sliding grooveand a stencil pushing opening. The control panel is inlaid in the upper portion of the surface of the left side of the stencil case and connected with the conveying table, the pressure sensor, the retractable pushing mechanism, the lifting gears and the sliding rollers in an electrical mode through electric wires. The automatic pushing device has the beneficial effects that the retractable pushing mechanism is arranged, by controlling the angle of the pushing mechanism, the pushing speed of the stencil is adjusted, and by controlling the extension and retraction state of the pushing mechanism, dust accumulation inside a pushing table and the automatic pushing device is prevented, so that smooth pushing of the stencil is guaranteed, meanwhile, the automatic pushing device is protected, andthe service life of the automatic pushing device is prolonged.

Description

technical field [0001] The invention relates to an automatic propulsion device for a template of a printing machine, which belongs to the field of printing machines. Background technique [0002] A machine for printing text and images. Modern printing machines are generally composed of plate loading, ink application, embossing, paper feeding (including folding) and other mechanisms. Its working principle is: first make the printing plate of the text and image to be printed, install it on the printing machine, and then apply the ink to the place where the text and image are on the printing plate manually or by the printing machine, and then transfer it directly or indirectly Print onto paper or other substrates such as textiles, sheet metal, plastic, leather, wood, glass, and ceramics to reproduce the same print as the printing plate. The invention and development of the printing press played an important role in the spread of human civilization and culture. The propulsion...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an automatic template propulsion device for a printing machine to solve the problem that the prior art template propulsion device for a printing machine cannot prevent the template from slipping from the side when it is propelled, and cannot control the template from being pushed into The speed in the printing machine is often caused by too slow speed to jam the board, or the speed is too fast to damage the printing machine, which affects the normal operation of the printing work.
