Description
Technical Field
[0001] This utility model relates to the field of coating device technology, specifically a PTFE coating uniform coating device. Background Technology
[0002] PTFE tapes are widely used in high-temperature processes in fields such as electronic component bonding, automotive manufacturing, food machinery, and wood processing due to their excellent high-temperature resistance, electrical insulation, and shielding properties. However, current production equipment has significant drawbacks: poor adhesive uniformity leads to delamination, and insufficient processing precision and low automation severely restrict product yield and production efficiency, making it difficult to meet the growing demand from the high-end market.
[0003] According to the patent application published on the patent website (authorization announcement number: CN221493079U), "This utility model proposes a PTFE tape coating machine, which is equipped with a coating machine base and a coating machine frame. A connecting support is installed between the coating machine frames. Four sets of guide rollers are installed on the inner side of the upper part of the coating machine frame, and a feeding roller adjusting bracket and feeding roller are installed on the outer side of the middle part. A pressure roller and a coating roller are installed on the inner side of the lower part of the coating machine frame. The pressure roller is installed on the coating machine by an adjusting cylinder." On the frame, fine-tuning mechanisms are set at the lower ends of the pressure rollers. The coating roller is mounted on the coating machine frame via a rotating shaft. The coating roller has a grid groove. A glue-dispensing trough is installed on the front side of the coating roller, and a coating scraper mechanism is installed on the rear side. The lower part of the coating scraper mechanism is connected to a swing blade motor. A coating drive motor is installed on the outside of the coating machine frame. The rotating parts of the PTFE tape coating machine adopt high-precision sliding bearings. It is equipped with an electric lifting glue-dispensing trough and an automatic swinging scraper, which can achieve ultra-high precision processing, make the coating more uniform, and effectively improve processing efficiency.
[0004] Regarding the above description, the applicant believes the following issues exist:
[0005] During use, this utility model can achieve ultra-high precision processing through the electric lifting glue tank and the automatic swing of the scraper, which can make the glue application more uniform and effectively improve the processing efficiency. However, during use, the amount of glue used in the glue tank is large. If it is not replenished in time, the subsequent glue application will be intermittent, resulting in uneven coating. Therefore, it is necessary to improve the PTFE coating uniform coating device to solve the above problems. Utility Model Content
