Front coating mechanism of main machine of primary-coating roll coating machine

Abstract

The invention relates to a front coating mechanism of a main machine of a primary-coating roll coating machine. The front coating mechanism is characterized by comprising a surface coating bracket, wherein a first sliding block is arranged at the bottom of the surface coating bracket and is matched with a first linear guiding rail; a second linear guiding rail is arranged on the upper surface of the surface coating bracket and is provided with a second sliding block which is fixed at the bottom of a surface coating roll bracket; a third linear guiding rail is arranged on the upper surface of the surface coating roll bracket, and is provided with a third sliding block which is fixed at the bottom of a surface coating belt roll bracket; an adjusting bracket is fixed at the end part of the surface coating roll bracket and is provided with a first worm-wheel and worm speed reducing box and a second worm-wheel and worm speed reducing box; a first screw rod is connected with the output end of the first worm-wheel and worm speed reducing box and is connected with the surface coating belt roll bracket; and a second screw rod is connected with the output end of the second worm-wheel and worm speed reducing box and is connected with the surface coating bracket. The front coating mechanism has the advantages that the gap between rolls can be adjusted and the service life of equipment can be guaranteed.

Description

technical field [0001] The invention relates to a surface coating mechanism on a coating machine for the production of color-coated plates, in particular to a front-side coating mechanism of a main body of an undercoating roller coater, and belongs to the technical field of color-coated plate production equipment. Background technique [0002] The roller coater is mainly used for chromizing, primer coating and finish coating in the color coating production line. The existing roller coater is generally composed of a dipping roller and a coating roller. The function of the dipping roller is to dip the paint on the tray Attached to the surface to transfer to the applicator roller, the function of the applicator roller is to evenly apply the paint transferred from the surface of the dipping roller to the surface of the substrate. In this process, the gap between the rollers determines the amount of paint and the effect of the application. [0003] The roller coating machine in ...

AI Technical Summary

Problems solved by technology

[0003] The roller coating machine in the prior art has the following defects: (1) It is difficult to adjust the gap between the rollers, and it must be adjusted repeatedly to achieve the desired effect; The roller is not stained with paint, and the paint needs to be added in time, which reduces the work efficiency
