Problems solved by technology

[0004] The above-mentioned equipment has the following defects: the above-mentioned scheme uses a vacuum pump to evacuate the body into a vacuum chamber to achieve the effect of laminating the original plate and the photosensitive plate. It is necessary to place the original plate on the photosensitive plate and then vacuumize it. There will be air bubbles, and it is difficult for the vacuum pump to remove the small air bubbles between the original plate and the photosensitive plate, which will affect the quality of the printing plate

Abstract

The invention relates to a printing-down machine. The printing-down machine comprises a machine body and a machine cover rotationally connected to the upper end of the machine body, a photosensitive plate is arranged on the machine body, and a printing down platform for an original edition to abut against is formed. A cover frame is mounted on the printing down platform, a containing groove communicating with the two side walls in the length direction is formed on the lower end face of the cover frame along the thickness direction, and a containing cavity for the original edition to penetratethrough and place in is formed. A pressing platform and a pressing assembly installed on the pressing platform are arranged at the feeding side of the machine body, and the pressing assembly comprisesa pressing roller abutting against the surface of the original edition and a pressure cylinder driving the pressing roller to roll in the length direction of the printing down platform. The printing-down machine has the effect of removing bubbles.

Description

technical field [0001] The invention relates to a printing machine. Background technique [0002] The printing machine is a kind of printing equipment widely used in the screen printing industry. It is a contact exposure imaging equipment used to make printing plates. It uses pressure to make the original plate and the photosensitive plate closely bonded, so that the original plate can be photochemically reacted. The image on the screen is accurately printed on the photosensitive plate. [0003] Chinese Patent Publication No. CN110161806A discloses a voltage-stabilizing plate printing machine, which includes a body, a cover plate is installed on the top of the body, telescopic rods are arranged on both sides of the cover plate and the body, and an operation console is arranged on the front surface of the body. The top of the machine is provided with a control panel, one end of the cover is provided with a handle, and the handle is located on the top of the console, one side...
