Micro-concave coating system and coating width control device thereof

Abstract

The invention discloses a coating width control device which comprises a film releasing mechanism, a film clamping mechanism and a plugging edge; the film releasing mechanism is arranged on one side of a micro-concave roll; the film clamping mechanism is arranged on the other side of the micro-concave roll; the two ends of the plugging edge are detachably connected with the film releasing mechanism and the film clamping mechanism respectively; the plugging edge is arranged between the micro-concave roll and a to-be-coated material in a penetrating manner, and is intersected with the micro-concave roll; and the width of the plugging edge is less than that of the to-be-coated material. Through the plugging edge arranged between the micro-concave roll and the to-be-coated material, the control on the coating width of the material is realized, so that unnecessary glue waste is avoided, a situation that the edge thickness of the material is not uniform resulting from glue flowing is avoided, and a series of subsequent processes like coating and winding can be ensured. The coating width control device is simple in structure and convenient to operate. The invention also discloses a micro-concave coating system provided with the coating width control device.

Description

technical field [0001] The invention relates to the technical field of dimple coating, in particular to a device for controlling coating width in dimple coating and a coating system with the device. Background technique [0002] In the coating industry, there is a coating method called dimple coating. The thickness and precision of dimple coating are all determined by dimple rollers. Usually, the width of the dimpled roller is larger than the width of the coating material. At present, there is basically no method and device for controlling the coating width in the industry, and all the materials are fully coated. However, in actual use, most coated products have edges of 0-20mm that are useless and need to be cut off. Therefore, the existing method of directly covering the entire width of the material has the following disadvantages: 1. Unnecessary waste of glue is caused; 2. Since the glue will not dry immediately after coating, the flow of glue will cause uneven thickness...

Therefore, the existing method of directly covering the entire width of the material has the following disadvantages: 1. Unnecessary waste of glue is caused; 2. Since the glue will not dry immediately after coating, the flow of glue will cause uneven thickness at the edge of the material , thus affecting a series of processes such as laminating and winding later
