Technical Field

[0001] The utility model relates to the field of micro-dimpled coating machines, in particular to a coating liquid circulation recovery mechanism for micro-dimpled coating machines. Background Art

[0002] The micro-dimpled coating machine is a coating method that applies a self-repairing protective agent on the surface of TPU, which can obtain a smooth, uniform and stable coating, thereby protecting the surface of the TPU substrate.

[0003] At present, when the micro-concave coater is coating, the coating liquid on the surface of the micro-concave plate roller contacts with the air after coating, which is easy to dry, thus easily causing waste of coating liquid and increasing economic costs. Therefore, a coating liquid circulation recovery mechanism for the micro-concave coater is designed. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a coating liquid circulation recovery mechanism for a micro-dimpled coating machine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model proposes a coating liquid circulation recovery mechanism for a micro-dimpled coating machine, comprising a coating liquid tank, both sides of the inner wall of which are rotatably connected with pressure rollers;

[0006] A circulation mechanism is provided inside the coating tank, and the circulation mechanism includes a fixed shaft, a rotating plate, a scraper, a micro-concave plate roller and a mounting shaft. The middle parts of both sides of the inner wall of the coating tank are rotatably connected with the mounting shaft that penetrates and extends to the outside of the coating tank, the outer ring of the mounting shaft is fixedly installed with the micro-concave plate roller, the right side of the front side of the coating tank is rotatably connected with a fixed shaft that penetrates and extends into the coating tank, one end of the fixed shaft located in the coating tank is fixedly installed with a rotating plate, and one side of the rotating plate is fixedly installed with a scraper connected with the micro-concave plate roller.

[0007] In one example, two connecting plates are fixedly mounted on both sides of the front side of the coating tank, and a motor is fixedly mounted on one side of one of the connecting plates.

[0008] In one example, a sleeve is fixedly mounted on the output shaft of the motor, and the sleeve passes through and extends outside the connecting plate, and a winding shaft is threadedly connected to one end of the sleeve away from the motor.

[0009] In one example, a pulley set is fixedly mounted on the outer ring of the sleeve, and the other end of the pulley set is fixedly connected to one end of the mounting shaft.

[0011] In one example, a crank is fixedly mounted on one end of the fixed shaft outside the coating tank.

[0012] The coating liquid recycling mechanism of the micro-dimpled coating machine proposed by the utility model can bring the following beneficial effects:

[0013] 1. The coating liquid recycling and recovery mechanism of the micro-concave coating machine can drive the fixed shaft to rotate by rotating the crank, and the scraper is driven by the rotating plate to fit with the surface of the micro-concave plate roller, so as to scrape off the coating liquid after being applied on the surface of the micro-concave plate roller, thereby preventing the coating liquid on the surface from drying and causing waste of the coating liquid. The coating liquid on the surface of the micro-concave plate roller is scraped off by the scraper, so that it flows into the coating liquid tank, thereby avoiding waste and achieving a recycling effect.

[0014] 2. The coating liquid circulation and recovery mechanism of the micro-concave coating machine drives the shaft sleeve to rotate by starting the motor, which will drive the material shaft to rotate and drive the substrate to rotate. At the same time, the rotation of the material shaft drives the installation shaft to rotate through the pulley group, and drives the micro-concave plate roller to rotate in the coating liquid tank, so that its surface is covered with coating liquid, and the surface of the substrate is coated, and the surface of the substrate is protected.
