Description

Technical Field

[0001] This utility model relates to the technical field of heat sealing devices, specifically a high-viscosity heat sealing device for plastic packaging bags. Background Technology

[0002] The heat-sealing principle of plastic packaging bags is based on the thermoplasticity of plastics. When heated, plastic softens and melts. When heated to a certain temperature, a certain pressure is applied, causing the molten plastic molecules to diffuse and permeate into each other. After cooling, a strong bond is formed, thus achieving the purpose of sealing.

[0003] During the heat sealing process, the pressing device comes into direct contact with the plastic packaging bag. If the surface of the pressing device is not clean or has problems such as wear or corrosion, impurities may remain. Existing heat sealing devices cannot clean the pressing device in time, causing impurities to affect the heat sealing strength. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, after the lifting plate moves downward, it moves downward through the first connecting plate and the rack. The rubber pad supports the heat-sealing plate, thereby driving the inner connecting rod to move upward along the outer connecting rod. The rack drives the gear to rotate, and the gear drives the rotating shaft to rotate. Through the transmission belt, the threaded rod rotates, driving the moving plate to move. The moving plate drives the rubber pad to move through the sliding rod. The rubber pad cleans the lower part of the heat-sealing plate. The spring pulls the lifting plate, and through the inner connecting rod, it drives the heat-sealing plate downward to press tightly against the rubber pad, improving the cleaning effect of the heat-sealing plate. When the lifting plate moves upward, the threaded rod rotates, allowing the rubber pad to be inserted into the lower part of the heat-sealing plate. The first inclined platform facilitates the upward movement of the heat-sealing plate, allowing the inner connecting rod to move upward along the outer connecting rod, making it easy for the rubber pad to enter the lower part of the heat-sealing plate and clean the lower part of the heat-sealing plate again. This can regularly clean the residue on the heat-sealing pressing device, keep it clean and smooth, and ensure the heat-sealing quality.

[0014] 2. This utility model also delivers water into the water pipe through the first hose and sprays it out through the nozzle. When the rubber pad moves to the top of the cleaning box, the top of the rubber pad is cleaned, which can remove impurities on the top of the rubber pad in time and prevent impurities from adhering and affecting the cleaning effect.

[0023] Working principle: In use, the packaging bag is placed on the processing seat 1 at the lower part of the heat-sealing plate 10. The hydraulic cylinder 4 drives the lifting plate 5 to move downward along the first support rod 2. The outer connecting rod 6 and the inner connecting rod 9 drive the heat-sealing plate 10 to move downward. The heat-sealing plate 10 contacts the packaging bag and heat-seales it. After the lifting plate 5 moves downward, it moves downward through the first connecting plate 21 and the rack 22. The rubber pad 16 supports the heat-sealing plate 10, thereby driving the inner connecting rod 9 to move upward along the outer connecting rod 6. The rack 22 drives the gear 20 to rotate, and the gear 20 drives the rotating shaft 19 to rotate. Through the transmission belt 23, the threaded rod 14 rotates, driving the moving plate 13 to move. The moving plate 13 drives the rubber pad 16 to move through the sliding rod 15. The rubber pad 16 supports the heat-sealing plate 10. The lower part is cleaned. Spring 8 pulls lifting plate 7, which in turn drives heat sealing plate 10 downward to press tightly against rubber pad 16 via inner connecting rod 9, improving the cleaning effect of heat sealing plate 10. When lifting plate 5 moves upward, threaded rod 14 rotates, causing rubber pad 16 to be inserted into the lower part of heat sealing plate 10. First inclined platform 17 facilitates pushing heat sealing plate 10 upward, causing inner connecting rod 9 to move upward along outer connecting rod 6, allowing rubber pad 16 to enter the lower part of heat sealing plate 10 and clean the lower part of heat sealing plate 10 again. First hose 31 sends water into water pipe 27 and sprays it out through nozzle 28. When rubber pad 16 moves to the upper part of cleaning box 25, the upper part of rubber pad 16 is cleaned. The cleaned water returns to water tank 29 through drain pipe 33 and second hose 35 for reuse.
