Roller coater

Abstract

The invention discloses a roller coater which comprises a painting roller, a roller coater rack, a solution-taking roller, a solution-taking roller rack and a roller rest pressure adjustment device, wherein the roller rest pressure adjustment device comprises an operating side bearing base, a driving side bearing base, a sliding block, a turbine worm, a pressure detection element, a handwheel, a servo motor, linearity guide rails and linearity rails. The roller coater provided by the invention achieves the technical purposes that the automatization feedback and adjustment of the roller coater are realized, and the reaction accuracy is improved. Through the roller coater disclosed by the invention, the pressure detection element contacting the spherical surface of the operating side bearing base and the spherical surface of the driving side bearing base is adopted, a signal is provided for the operation of the servo motor, the regulation and control of a roller interval are beneficial, the accuracy and consistency of the thickness of a painting film are improved, and the quality of the painting film of the surface of a steel band and quality stability are guaranteed.

Description

technical field [0001] The invention relates to a steel strip surface coating equipment, in particular to a roll coating machine. Background technique [0002] In order to improve the corrosion resistance of the steel plate and enhance its corrosion resistance to the surrounding environment, using surface engineering technology to process the surface of the steel plate is an effective method currently adopted in this field. According to the surface engineering technology, the technology of forming the surface coating layer can be divided into: surface conversion technology, thin film technology and coating technology. However, the rapidly developing coating technology is a relatively simple and effective method to improve the corrosion resistance of steel plates. Coating is usually carried out on flat materials using a roller coater. The full name of the roller coater is a roller coater, which is a device that uses more than one set of rotary rollers to apply a certain...

AI Technical Summary

Problems solved by technology

However, the existing roller coating machine has the following defects: 1) The adjustment of the pressure by the roller is mainly done manually, and it cannot be adjusted in time when the diameter of the roller is worn; The friction force of the liquid roller 4 and its frame 5 acting on the linear guide rail 9, so when the linear guide rail 9 jams, the frame loss of the detection value of the roller pressure is serious, which affects the control of the coating film; 3) When the coating roller appears When the pressure between the rollers on both sides is inconsistent due to wear on one side, due to the characteristics of the linear guide rail, effective adjustment and control of the pressure between the rollers on one side cannot be performed, thus affecting the quality of the coating film

The uniformity and stability of the coating thickness are difficult to control, and the accuracy is not high
