Improved two-side offset paper coating machine

Abstract

The invention provides an improved two-side offset paper coating machine and relates to the field of paper making technical equipment. The machine comprises an uncoiling device, a first guide roller,a coating device, a drying device, a second guide roller and a coiling device. The coating device is an enclosed box, the two sides of the enclosed box are provided with an inlet and an outlet. A coating roller set is arranged in the enclosed box, an ink groove is formed below the coating roller set, the bottom of the ink groove is provided with a pressure sensor, the ink groove is connected witha container through a connection pipe, the connection pipe is provided with a switching valve, the switching valve is electrically connected with the pressure sensor, a stirring disc is arranged at the bottom of the container and connected with a motor below the container, and a temperature controller is arranged in the enclosed box. The improved two-side offset paper coating machine has the beneficial effects that the coating quality is good, the automation degree is high, the skinning rate of glue, coating, ink and other media which are placed in the coating mechanism is low, and economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to an improved offset paper coating machine. Background technique [0002] The coating machine is mainly used for the surface coating process of film, paper, etc. This machine is to coat the rolled substrate with a layer of glue, paint or ink with specific functions, and then wind it up after drying. The coating process is multi-purpose It is used for printing magazines, books and other publishing papers, as well as printing papers for trademarks, packaging and catalogs. [0003] Double-adhesive paper has many advantages such as small stretchability, uniform ink absorption, good smoothness, tight texture and opaque, strong water resistance, etc., so it is widely used in various printed matters. Coating work according to printing needs. And under the prior art, there is following defect in using traditional coating machine: (1) mediums such as glue, coating or printin...

AI Technical Summary

Problems solved by technology

And under the prior art, there is following defect in using traditional coating machine: (1) mediums such as glue, coating or printing ink are due to being subjected to production environment or in coating machine static time too long, before the ink tank has not rolled paper, Skinning has occurred, which not only increases the cost, but also affects the coating quality; (2) lacks the length measurement of the winding paper, although the application number 201120415116.3 discloses a coating machine with a calculated length of the winding paper, but it is accurate (3) The current degree of automation of coating machines is not high, which increases the burden on operators
