Back adhesive coating and dispensing pool for printing machine

Abstract

The invention discloses a back adhesive coating and dispensing pool for a printing machine. The back adhesive coating and dispensing pool comprises a machine frame, an adhesive pool is arranged at theinner bottom of the machine frame, an adhesive coating and dispensing roller is arranged inside the adhesive pool, a hydraulic cylinder is arranged at the top of the machine frame, a piston rod is arranged at the lower portion of the hydraulic cylinder, a lifting frame is arranged at the lower end of the piston rod, a first installation portion is arranged on one side of the lifting frame, the two sides of the lower portion of the first installation portion are provided with first positioning cylinders, a driven roller is arranged between the first positioning cylinders in a sleeving mode, asecond installation portion is arranged on the other side of the lifting frame, second positioning cylinders are arranged on the two sides of the lower portion of the second installation portion, a driving roller is arranged between the second positioning cylinders in a sleeving mode, the driving roller corresponds to the driven roller, the adhesive coating and dispensing roller comprises an adhesive coating and dispensing roller main body, and a plurality of adhesive coating and dispensing convex portions are arranged on the outer peripheral surface of the adhesive coating and dispensing roller main body. According to the back adhesive coating and dispensing pool for the printing machine, paper can be attached to the surface of the adhesive coating and dispensing roller, the adhesive coating and dispensing roller can conveniently perform adhesive coating and dispensing treatment on the paper through the adhesive coating and dispensing convex portions, so that the adhesive coating anddispensing treatment efficiency is greatly improved.

Description

technical field [0001] The invention relates to an upper dispensing pool, in particular to an upper dispensing pool for back glue used in printing machines. Background technique [0002] A printing press is a machine that prints text and images. Modern printing machines are generally composed of plate loading, ink application, embossing, paper feeding 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 Printing onto paper or other substrate 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. Flat screen curved surface screen printing refers to screen printing with a flat screen on a cyli...
