Description

Technical Field

[0001] This utility model relates to the technical field of PVC sealant devices, specifically a PVC weld sealant application device. Background Technology

[0002] PVC weld sealant is a product of the reaction between polyisocyanates and polyols. Because its main resin molecules contain a large number of polar and reactive groups, it exhibits excellent adhesion to various substrates and can cure at room temperature. Using a PVC weld sealant application device can significantly improve the quality of the application process.

[0003] Upon investigation, a glue application gun and device with publication number CN222606940U were found. The device includes a glue delivery pipe and a nozzle connected to the glue delivery pipe. This nozzle is used to address the problem that thermally expanding air can easily enter the sealing strip, causing air bubbles to form on the surface of the sealing strip. However, the glue application mechanism in this practical application lacks an adjustment mechanism to regulate the glue application direction and height, and there is no structure to improve the uniformity of glue application, resulting in poor glue application quality. Therefore, we propose a PVC weld sealant application device. Utility Model Content

[0022] Working principle: For this type of PVC weld sealant application device, the operator first connects the sealant input source to the feed pipe 7 via a flange to ensure a stable supply of sealant material. Then, the operator adjusts the lifting platform 1 and the application pipe 13 according to the weld size and height to be coated.

Meanwhile, the output shaft of the second motor 10 drives the drive gear 11. When rotating in both directions, the drive gear 11 can rotate the gear ring 9 and the rotating flange 8 at one end of the feed pipe 7 to adjust the coating angle of the glue-coating pipe 13 at the other end of the connected feed pipe 12, thereby controlling the coating direction and improving the coating quality. Finally, the spiral shaft 14 and the guide rod 15 inside the glue-coating pipe 13 extend the travel length of the glue, allowing the glue to be fully mixed and uniform within the glue-coating pipe 13. The guide rod 15 can also help control the direction of the glue as it flows out of the glue-coating pipe 13, thereby improving the coating quality and enhancing the applicability of the device.
