Coating device provided with slurry recycling structure and used for supercapacitor production

Abstract

The invention discloses a coating device provided with a slurry recycling structure and used for supercapacitor production, which comprises a rack, an unwinding roller, an extrusion mechanism, a drying mechanism, a drive mechanism, a winding roller, a guide roller, a lifting mechanism and a coating mechanism, wherein the unwinding roller, the guide roller, the extrusion mechanism, the lifting mechanism, the coating mechanism, the drying mechanism, the extrusion mechanism, the driving mechanism, the guide roller and the winding roller are sequentially arranged in front of the rack from one sideto the other side. Due to the arrangement of the guide roller, the function of guiding materials is achieved, the materials are prevented from deviating, the stability of material conveying is achieved, and the device is suitable for the materials with different widths; Due to the arrangement of the coating mechanism, the problems that due to the fact that slurry has certain fluidity, the thickness of the slurry becomes small, and the production quality is not facilitated are solved; and through the arrangement of the collecting box, the problems of unnecessary waste of slurry, equipment pollution and equipment cleaning difficulty increase are solved.

Description

technical field [0001] The invention relates to the technical field of supercapacitor production, in particular to a coating device with a slurry recovery structure for supercapacitor production. Background technique [0002] The manufacturing process of supercapacitors is mainly composed of batching, beating, coating, rolling, slitting, winding, laser welding, packaging, liquid injection, activation, testing, packaging and other processes. Among them, a coating machine is needed in the coating stage, and the function of the coating machine is to uniformly coat the slurry on the surface of the aluminum foil (or copper foil) according to a predetermined thickness and length. The aluminum foil (or copper foil) is automatically corrected and discharged by the feeding mechanism through tension control, and the slurry is transferred and coated on the surface of the foil strip through servo control. The coated aluminum foil (or copper foil) is dried in a drying box and passed thro...

AI Technical Summary

Problems solved by technology

The lifting mechanism includes a second cylinder, a connecting frame, a mounting plate, and a guide roller. The second cylinder is connected to the front of the frame by bolts, and the bottom of the output end of the second cylinder is connected to the connecting frame by bolts. , two obliquely arranged mounting plates are welded below the connecting frame, and the two ends of the two mounting plates are rotatably connected with the guide rollers, so that the connecting frame can be driven up by the second cylinder, and the connecting frame Drive the installation plate to rise, and the installation plate drives the guide roller to rise, so that the guide roller comes out from the inside of the coating box, which facilitates the installation of materials. The coating mechanism includes a coating box, a discharge port, a scraper, a collection box, and a return pipe 1. Feed pipe, the coating box is connected to the front of the frame by bolts, and is located below the lifting mechanism, the side of the coating box away from the unwinding roller is welded with the collection box and the discharge port is provided, and the discharge port is located above the collection box, the side of the discharge port close to the collection box is provided with the scraper that can move up and down. The bottom at the rear of the coating box is connected to the feed pipe through a throat hoop, the bottom at the rear of the collection box is connected to the return pipe through a throat hoop, and the feed pipe is connected to the material box through a water pump. The head box is connected, so that the material is coated horizontally, and the height of the scraper can be adjusted to control the thickness of the slurry coating, which solves the problem of slurry coating due to the certain fluidity of the slurry. The thickness becomes smaller, which is not conducive to the problem of production quality. The setting of the collection box realizes the collection of the slurry overflowing from the discharge port, and returns it to the material box through the return pipe, which solves the unnecessary waste of slurry and pollutes the Equipment, a problem that increases the difficulty of cleaning equipment
