Description

Technical Field

[0001] This utility model relates to the field of plastic woven bag production technology, specifically to a raw material melting device for plastic woven bag production. Background Technology

[0002] Woven plastic bags are bags made of plastic materials such as polyethylene (PE) or polypropylene (PP). They are widely used in agriculture, construction, industry, and daily life due to their durability, lightweight, and water resistance. They have good tensile strength, can bear heavy loads, and can be customized in different sizes and colors to meet specific needs. Furthermore, many woven plastic bags are recyclable, meeting environmental protection requirements and making them an indispensable choice in modern packaging.

[0003] In the production of plastic woven bags, the most common mixing method is screw mixing. This method uses the rotational motion of the screw to mix the raw materials evenly and push the molten material forward. The screw can be designed as a single screw or a twin screw, which can handle plastics of different viscosities and has become the most common mixing method in plastic melting equipment.

[0004] In existing technologies, the stirring method of furnace devices cannot ensure sufficient mixing of raw materials. During the raw material melting process, unmelted raw materials tend to stick to the inner wall of the mixing tank, making them difficult to clean and resulting in material waste. Furthermore, when cleaning the mixing tank, it is impossible to scrape or wipe the inner wall. To address these issues, a raw material melting device for plastic woven bag production is proposed. Utility Model Content

The elasticity of the first spring 19 keeps the brush 18 and scraper 17 in close contact with the inner wall of the mixing tank 6, scraping the plastic raw material adhering to the inner wall of the mixing tank 6. The melted plastic raw material falls from the mixing tank 6 into the conveyor 4. The second servo motor 13 drives the spiral conveyor 12 to transport the melted material. It enters the upper storage tank 10 and the lower storage tank 9 through the telescopic frame 11. The valve 21 can be opened and closed. The molten raw materials are transported by means of ventilation and hot air circulation achieved by heating the fan 32 and the inside of the filter screen 20. When cleaning the storage box, the telescopic frame 11 is first disassembled at the bottom of the conveyor 4 through the threaded hole 27. Then, the third fixing block 31 is pulled, which causes the third fixing block 31 to move the pin 26 upward. The third fixing block 31 is fixed above the upper fixing block 24. The upper storage box 10 and the lower storage box 9 are disassembled by sliding the upper storage box 10. During installation, the third fixing block 31 is rotated, and the second spring 29 rebounds, fixing the pin 26 in the lower fixing block 23. This allows the upper storage box 10 and the lower storage box 9 to be disassembled and installed.
