Abstract
Description
Technical Field
[0001] The invention relates to the technical field of glue coating equipment, in particular to the technical field of glue baffles. Background Art
[0002] The comma coater evenly spreads the liquid material on a flat surface through its special coating head - the comma scraper. The comma scraper is fixed and does not rotate. Its notched edge faces the tangent point of the coating roller or the backing roller, scraping off the coating that has passed through, thereby evenly applying a new coating. This coating method can achieve precise control of the coating thickness, and the coating is uniform and the coating surface is flat.
[0003] When the existing comma coater is in use, liquid glue is stored in a glue tank, and a coating roller is rotatably installed at the discharge end of the glue tank. A glue baffle is provided between the glue tank and the coating roller. Since the coating roller is rotating, the glue baffle cannot be well sealed with both sides of the coating roller. The glue in the glue tank will overflow from the contact surface between the glue baffle and the coating roller, resulting in waste. Summary of the invention
[0004] The purpose of the present invention is to solve the problems in the prior art and to provide a comma transfer coating glue baffle that can solve the above problems.
[0005] To achieve the above-mentioned purpose, the present invention proposes a comma transfer coating glue baffle, including a baffle body, a coating installation groove matching with a coating roller is provided on the baffle body, a scraper installation groove matching with a comma scraper is also provided on the baffle body, a liquid injection cavity is provided inside the baffle body, a liquid outlet connected to the liquid injection cavity is provided on the coating installation groove, the liquid outlet matches with the coating roller, the liquid injection cavity is connected with a liquid tank, the liquid tank is filled with glue solvent, and the liquid tank is connected with compressed air.
[0006] Preferably, the baffle body is a double-layer structure, comprising a main board and a hollow board, a liquid injection cavity is provided on the hollow board, and a liquid injection hole matching the liquid injection cavity is provided on the hollow board.
[0007] Preferably, a liquid inlet joint is installed on the liquid injection hole, and the liquid inlet joint is connected to the liquid tank through a liquid infusion pipeline.
[0008] The present invention also proposes a comma transfer coating device, comprising the above-mentioned baffle body, glue tank, coating roller, comma scraper and back roller, wherein a coating roller is rotatably installed at the bottom of the glue tank, a comma scraper is arranged above the coating roller, glue baffles are arranged on both sides of the glue tank, the coating roller is installed in the coating installation tank, the comma scraper is installed in the scraper installation tank, and a back roller is arranged on the side of the coating roller away from the glue tank Preferably, a gap is left between the coating installation groove and the coating roller.
[0009] Beneficial effects of the present invention: the present invention opens a liquid injection cavity in the glue baffle plate, and injects pressurized glue solvent into the liquid injection cavity by compressed air. The glue solvent overflows from the coating installation groove to form a positive pressure liquid seal, which effectively prevents the glue from overflowing therefrom. The solvent can also offset the increased viscosity of the glue liquid when it contacts the glue baffle plate, so that the coating roller rotates smoothly, ensuring that the coating work proceeds smoothly.
[0010] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0013] See also Figure 1 , Figure 2 , Figure 3 A comma transfer coating device comprises a baffle body 1, a glue tank 2, a coating roller 3, a comma scraper 4 and a backing roller 5, wherein the coating roller 3 is rotatably mounted at the bottom of the glue tank 2, a comma scraper 4 is arranged above the coating roller 3, glue baffles are arranged on both sides of the glue tank 2, the coating roller 3 is installed in a coating installation groove 11, the comma scraper 4 is installed in a scraper installation groove 12, a backing roller 5 is arranged on the side of the coating roller 3 away from the glue tank 2, a coating installation groove 11 matching with the coating roller 3 is opened on the baffle body 1, a scraper installation groove 12 matching with the comma scraper 4 is also opened on the baffle body 1, and a backing roller 5 is arranged on the baffle body 1. A liquid injection cavity 13 is provided on the coating installation groove 11, a liquid outlet 14 connected to the liquid injection cavity 13 is provided, the liquid outlet 14 is matched with the coating roller 3, the liquid injection cavity 13 is connected to a liquid tank, the liquid tank is filled with glue solvent, the liquid tank is connected to compressed air, the baffle body 1 is a double-layer structure, the baffle body 1 includes a main board 6 and a hollow plate 7, the hollow plate 7 is provided with a liquid injection cavity 13, the hollow plate 7 is provided with a liquid injection hole 15 matching the liquid injection cavity 13, the liquid injection hole 15 is installed with a liquid inlet joint, the liquid inlet joint is connected to the liquid tank through an infusion pipeline, and the solvent is butanone.
[0014] The compressed air pressurizes the solvent in the liquid tank. The pressurized solvent enters the liquid injection cavity from the injection hole, and then overflows from the liquid outlet. The overflowed solvent enters the gap between the glue baffle and the coating roller. The solvent carries positive pressure to prevent the glue from overflowing. The solvent can also offset the increased viscosity of the glue when it contacts the glue baffle. The solvent in the gap has a certain lubricating effect on the coating roller, which can ensure the smooth rotation of the coating roller.
[0015] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
