Description

Technical Field

[0001] The utility model relates to the technical field of fabric processing, in particular to a coating device for structural color cotton fabrics used in textiles. Background Art

[0002] The original meaning of textile is a general term for spinning and weaving, but with the continuous development and improvement of the textile knowledge system and discipline system, especially the emergence of non-woven textile materials and three-dimensional composite weaving technologies, it is no longer just traditional hand-spinning and weaving, but also includes non-woven technology, modern three-dimensional weaving technology, modern electrostatic nano-netting technology and other production of clothing, industrial and decorative textiles.

[0003] At present, after the initial processing and shaping of industrial fabrics, some products with certain characteristics require the surface of the industrial fabric to be coated with a thermal insulation coating. According to a coating device for processing thermal insulation coatings on industrial fabrics described in patent number CN216891537U, when in use, the upper and lower coating rollers are used to simultaneously coat both sides. At this time, the upper coating liquid box is affected by gravity, and the internal glue will fall, resulting in uneven coating on both sides, affecting the quality of the final product. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a coating device for structural color cotton fabrics for textiles, which solves the above-mentioned problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A coating device for structural color cotton fabric for textiles, comprising a frame, a guide roller rotatably arranged above the frame for guiding the fabric, and a coating mechanism for coating the fabric, wherein two guide rollers are provided, and the two guide rollers are staggered up and down so that the fabric is turned over for transportation;

[0006] The coating mechanism includes two coating boxes fixed above the frame, and the two coating boxes are respectively arranged in the output direction after the fabric passes through the two guide rollers. The inner cavities of the two coating boxes are rotatably connected to coating rollers in contact with the internal coating liquid, and the two coating rollers are in contact with the upper and lower surfaces of the fabric respectively. The bottom of the coating box is fixedly connected to an upper cover body, and the top of the inner cavity of the upper cover body is fixedly connected to an electric heating plate abutting the bottom of the coating box. One side of the upper cover body is connected to the external fan through an air intake duct, and the bottom of the upper cover body is provided with an opening facing the coating surface of the fabric. When in use, the fabric is transported to the top of the upper coating box, and the coating rollers touch the bottom of the fabric. The fabric is then transferred downwards by the guide roller and the excess coating on the surface is scraped off by the scraper. The excess coating accumulates on one side of the scraper and is then discharged from both sides of the scraper through the guidance of the conical raised section and falls on both sides of the fabric. The coating droplets output through the conical raised section are collected in the collection box and transported to the bottom of the upper cover. The air intake duct outputs hot air to dry the coated surface of the fabric and then the above operation is repeated on the other side through the guidance of the guide roller. The upper and lower surfaces of the fabric can be evenly coated, so that the coating on both sides is more uniform, the quality of the finished product is better, and the coating can be effectively flattened and dried.

[0007] As a further solution of the present invention: one side of the coating box is fixedly connected to a scraper facing the guide roller, the bottom of the scraper is in contact with the coating on the surface of the fabric, and a conical raised section is provided on one side of the scraper. After the fabric coated by the coating roller is diverted and transported by the guide roller, the excess coating on the surface is scraped by the scraper. The excess coating accumulates on one side of the scraper, and then is discharged from both sides of the scraper under the guidance of the conical raised section and falls on both sides of the fabric. The coating liquid output through the conical raised section drips into the collection box for collection.

[0008] As a further solution of the present invention: the coating equipment for structural color cotton fabrics for textiles described in claim 1 is characterized in that a collecting box located below the scraper is fixedly connected to one side of the frame, and the coating liquid output through the conical raised section drips into the collecting box for collection.

[0009] As a further solution of the present invention: the inner cavity of the coating box is rotatably connected to an auger, the surface of the auger rotating shaft is fixedly connected to a toggle rod, and the shaft end of the coating roller is fixedly connected to an active rod that abuts the surface of the toggle rod. When the coating roller rotates to coat the fabric, the toggle rod is driven to rotate by the active rod, which drives the auger to rotate to stir the internal glue liquid, and at this time the electric heating plate in the upper cover body is heated, which can ensure the uniformity of the glue liquid and prevent it from clumping and solidifying, and the final product has a better effect.

[0010] As a further solution of the present invention: the contact point between the coating box and the electric heating plate is a metal plate, which has a better heat conduction effect. The electric heating plate can heat the coating liquid inside the coating box while blowing out hot air to shape the coating to prevent it from solidifying.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The utility model repeats the above operation on the other side after the guide roller is turned over to coat the fabric, and the upper and lower sides of the fabric can be evenly coated, so that the coating on both sides is more uniform, the quality of the finished product is better, and the coating can be effectively spread and dried.

[0013] 2. In the present invention, when the coating roller rotates to coat the fabric, the active rod drives the toggle rod to rotate, which drives the auger to rotate to stir the glue inside. At this time, the electric heating plate in the upper cover body is heated to ensure the uniformity of the glue, prevent it from clumping and solidifying, and finally the finished product has a better effect.
