Coating machine

Abstract

The invention discloses a coating machine. The coating machine comprises a frame; an impressing roller is arranged on the frame; a moving table movably mounted on the frame is arranged on one side of the impressing roller; an intaglio roller near or far from the impressing roller along with movement of the moving table is arranged on the moving table; the frame is provided with two sets of driving mechanisms for driving the moving table to move near or far from the impressing roller; and the two sets of driving mechanisms are respectively connected with two sides of the moving table. As the two sets of driving mechanisms synchronously drive the moving table to perform a reciprocating motion, the technical problems of desynchrony and hysterisis caused by different resistance on two sides of the moving table are solved, the coating machine reduces the assembly precision, the intaglio roller mounted on the moving table can be guaranteed to generate no deviation phenomenon in the reciprocating motion process, the coating quality of the coating machine is guaranteed, and the improvement of product pass percent is facilitated.

Description

technical field [0001] The invention relates to a coating machine. Background technique [0002] As we all know, the coating head of the existing mechanical bounce coating machine generally adopts a gap clutch structure driven by a single motor and a single ball screw pair, and the single ball screw pair is connected with the middle position of the moving table. Disadvantages are: higher requirements on the processing accuracy of the mobile platform and the assembly of various accessories. [0003] When the coating machine is in production, the mobile table is in a state of rapid reciprocating movement. Due to the resistance on both sides of the mobile table and the assembly and processing precision, it is difficult to achieve complete consistency. The phenomenon, resulting in the production of patterns and gaps, often appear bell mouth, abnormal size fluctuations, affecting the product qualification rate. Contents of the invention [0004] In order to solve the above pr...

Disadvantages: high requirements for machining accuracy of the mobile platform and assembly of various accessories

[0003] When the coating machine is in production, the mobile table is in a state of rapid reciprocating movement. Due to the resistance on both sides of the mobile table and the assembly and processing precision, it is difficult to achieve complete consistency. The phenomenon, which leads to the production of patterns and gaps are left blank, and the bell mouth often appears, and the size fluctuates abnormally, which affects the product qualification rate
