Precise multi-roller coating mechanism

Abstract

The invention aims at providing a precise multi-roller coating mechanism with which the positioning is rapidly and accurately realized by using a metering roller. A transferring steel roller rotates and axially shifts. A transferring rubber roller respectively adjusts the working pressures of the transferring steel roller and a coating steel roller, such that the defects of the mechanism are overcome. With the mechanism, the positioning is convenient, the repeatability is good, the adjusting method is flexible, the application range is wide, and the coating is uniform and stable. During the application process of the mechanism, the working efficiency is improved, the coating technology is improved, the production cost is reduced, the composite quality can be improved, and the rejection rate is reduced.

Description

technical field [0001] The invention relates to a precision multi-roller coating mechanism, which includes metering rollers, transfer steel rollers, transfer rubber rollers, coating steel rollers, coating rubber rollers, metering roller adjustment positioning seats, transfer steel roller adjustment positioning seats, transfer steel Roller rotation and serial movement mechanism. technical background [0002] With the continuous development of the printing and packaging industry, many equipment manufacturers have improved or newly designed the local structure and performance of the composite machinery to improve the performance of the machinery. However, few manufacturers have designed and improved the coating mechanism perfectly, and most of them still follow the traditional multi-roller (two-roller, three-roller, four-roller or five-roller) coating mechanism, the most typical of which is the five-roller design structure( figure 1 ), the disadvantage of this mechanism is: d...

Problems solved by technology

However, few manufacturers have designed and improved the coating mechanism perfectly, and most of them still follow the traditional multi-roller (two-roller, three-roller, four-roller or five-roller) coating mechanism, the most typical of which is the five-roller design structure( figure 1 ), the disadvantage of this mechanism is: during the coating process, if the glue on the transfer steel roll cannot be evenly transferred to the coating steel roll, white spots or bubbles will appear during the compounding process, which will cause the produced product to be invalid ;The pressure adjustment on both sides of the transfer rubber roller is difficult, which makes it difficult to control the glue consistency of the composite film in the width direction; the gap adjustment time of the metering roller is too long and the repeatability is poor, etc.
