Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically a coating mechanism for tape production. Background Technology

[0002] A coating machine is an industrial machine specifically designed for precise coating operations on the surfaces of various materials. Its main function is to apply liquid (or melt) materials such as adhesives, coatings, or slurries to the surface of a substrate in a quantitative and uniform manner. This equipment is widely used in many industrial fields, including shoe material manufacturing, electronics production, sponge processing, EVA material processing, PE material processing, and fabric processing.

[0003] For example, patent number CN 210207417 U discloses a coating mechanism for a coating machine, including a frame, a first hopper, and a second hopper. The first hopper is located at the lower end of the frame, and the second hopper is located above the first hopper. The two ends of the first and second hoppers are evenly and fixedly connected to the frame. A first coating roller is located above the first hopper, and both ends of the first coating roller are rotatably connected to the frame. A second coating roller is located above the second hopper, and both ends of the second coating roller are rotatably connected to the frame. A turning roller is located between the first coating roller and the second hopper, on one side of the first hopper. One end of the turning roller is rotatably connected to the frame, and the other end is fixedly connected to a rotating motor. The top of the first coating roller is higher than the bottom of the turning roller. This utility model provides a coating mechanism for a coating machine, and a coating mechanism capable of double-sided coating of a substrate.

[0004] For example, patent number CN 219129726 U provides a coating mechanism for a coating machine, relating to the field of coating machine technology. This utility model includes a main body, a feed inlet, and a coating mechanism. The feed inlet is located on the side of the main body, and the coating mechanism is located inside the main body. A discharge outlet is located on the other side of the main body. Coating rollers are arranged on both sides inside the coating mechanism, and a tension roller is arranged between the coating rollers. A balance frame is located at the bottom of the coating mechanism, and guide rollers are arranged on both sides above the balance frame. The guide rollers are respectively located on the sides of the feed inlet and the discharge outlet. In existing coating machines, during the processing of rolled coating raw materials, the guide rollers in the coating mechanism are prone to slack when transporting the coating raw materials. When the push plate presses down or pulls up the tension spring below, the pressure generated by the pressure spring adjusts the tension of the tension roller below the support, thus preventing uneven force distribution during the processing of the coating raw materials.

[0005] While the first patent utilizes a hopper and coating roller for coating, its open mechanism allows dust to contaminate the coating, degrading coating quality and affecting the tape's performance and appearance. Furthermore, the open structure hinders precise control of coating temperature and humidity, potentially altering its flowability and viscosity, thus impacting coating uniformity. The second patent addresses the issue of loose material transport during coating, but its closed structure necessitates disassembly for installation, requiring material to enter through the inlet and exit through the outlet. This cumbersome operation and the need for multiple operators reduce efficiency. Adding a bag installation port would waste materials and increase operating costs. Utility Model Content

[0025] In use, place the fabric on the material roller 31, then pull out one end of the fabric. First, pass it over the feed guide roller 32, then through the guide rod 61. Then rotate the guide rod 61 to make the fabric wrap around it. After wrapping it two or three times, move the guide rod 61 to the right along the guide groove 6. When it reaches the far right, rotate the guide rod 61 in the opposite direction to loosen the fabric.
