Description

Technical Field

[0001] The utility model relates to the technical field of propulsion equipment, in particular to a printing press template propulsion device. Background Art

[0002] A printing press is a machine for printing text and images. The text and images to be printed are first made into a printing template and installed on the printing press. Ink is then applied to the places with text and images on the printing template manually or by the printing press. The ink is then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics) to reproduce printed products identical to the printing template. For high-definition and environmentally friendly printing, manual installation is generally used during the installation of the printing template.

[0003] After searching, the utility model with announcement number CN212219636U discloses an automatic pushing device for printing machine template, including a mounting plate, on which an automatic replacement pushing structure is installed; the automatic replacement pushing structure includes: a direct sales screw module, a mounting block, a first electric push rod, a connecting block, a connecting rod, a connecting plate, a servo motor, a fixed plate, a pair of second electric push rods with the same structure, a pair of clamping plates with the same structure, a third electric push rod and a push plate; the automatic replacement pushing structure is used to realize automatic replacement of the printing template and push the printing template during insertion, so that the printing template is pushed into the template socket of the printing machine for insertion.

[0004] The device also has the following disadvantages during use: when in use, the template is pushed to move by the splint and the direct-screw screw module, and the template is placed in the printing machine. However, after the template is pulled out and placed, the paint on the template will solidify, affecting subsequent use. It is very inconvenient to use. If it is cleaned manually, it is time-consuming. Utility Model Content
