Description

Technical Field

[0001] This utility model relates to the field of thin film processing technology, specifically to a polyurethane calendered thin film processing device. Background Technology

[0002] High-permeability, internally micro-pressure medical polyurethane film is a high-performance material widely used in the medical field, especially in dressings and fixation devices. Due to its excellent performance and wide range of applications, high-permeability, internally micro-pressure medical polyurethane film has become an important material in the medical field. Medical polyurethane film is commonly used in wound dressings and medical devices, effectively preventing the invasion of bacteria and contaminants, while its breathability allows oxygen and water vapor to pass through, reducing edema around the wound and lowering the risk of infection.

[0003] A search revealed a polyurethane calendering film processing apparatus with publication number CN212352649U, comprising a machine body, guide ports symmetrically arranged on the surface of the machine body, guide posts slidably arranged on the inner side of the guide ports, a mounting frame welded to the upper end of the guide posts, a second pressure roller mounted on the inner side of the mounting frame, a first pressure roller mounted on the inner side of the machine body, a first motor connected to one end of the first pressure roller, and the first motor mounted on the side of the machine body;

[0004] Polyurethane films require calendering to achieve the desired thickness during processing. Traditional processing equipment lacks a cleaning structure after calendering, leading to surface dust accumulation on the polyurethane film, which affects the quality of subsequent finished products and the accuracy of subsequent testing. To address this, we propose a polyurethane calendered film processing device. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a polyurethane calendered film processing device. The device uses a lead screw to adjust the distance between the pressing roller and the calendering roller to control the thickness of the polyurethane film. The static eliminator, together with the dust-adhesive roller, can clean the dust and other impurities on the surface of the polyurethane film, thereby improving the accuracy of subsequent testing. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a polyurethane calendered film processing device, comprising a worktable and a pressing roller;

At the same time, the spring contraction causes the two dust-adhesive rollers to automatically adhere to the surface of the polyurethane film to remove dust and impurities. This can improve the quality of the subsequent finished product and prevent dust and other impurities from adhering and affecting the accuracy of subsequent detection.

[0012] Furthermore, the detection unit also includes a detection camera, a frame, and a lighting lamp.

The input end of the electric push rod is electrically connected to the output end of the controller. The electric push rod is activated to adjust the position of the limiting frame, thereby solving the problem of polyurethane film misalignment.

[0014] Furthermore, it also includes a distance sensor, of which there are two and are respectively installed in two grooves on the front side of the frame. The output of the distance sensor is electrically connected to the input of the controller. The distance sensor can accurately detect the distance between the pressing roller and the calendering roller, thereby improving the accuracy of the polyurethane film calendering thickness.

This allows control over the thickness of the polyurethane film.

[0017] 2. The static eliminator can remove static electricity from the surface of the polyurethane film. At the same time, the spring contraction causes the two dust-adhesive rollers to automatically adhere to the surface of the polyurethane film to remove dust and impurities, thus improving the quality of the subsequent finished products.

[0018] 3. Illumination is provided to the surface of the polyurethane film by a lighting lamp, and the installed inspection camera can detect cracks and fractures on the surface of the polyurethane film.
