Description

Technical Field

[0001] This utility model relates to the field of embossing pretreatment technology for plastic flooring, specifically to an embossing pretreatment device for processing plastic flooring. Background Technology

[0002] Plastic materials often possess a certain rigidity at room temperature, requiring immense pressure for direct embossing. This places excessive demands on the performance of the embossing equipment and can easily lead to overload and damage. Heating raises the temperature of the plastic flooring, intensifying the movement of its molecular chains, softening the material, and significantly enhancing its plasticity. This allows for clear and regular embossing results under lower pressure, protecting the equipment and improving production efficiency.

[0003] Chinese patent CN221417435U discloses a pre-treatment device for embossing plastic flooring, belonging to the field of plastic flooring processing technology. The device includes a support base, with a power frame, cutting frame, transfer frame, and conveyor frame mounted on its upper surface. A cutting and leveling blade is slidably installed inside the cutting frame. A drive motor is located on one side of the conveyor frame. A fixed seat is located on the upper surface of the support base, and a dust removal and heating integrated structure is located on one side of the upper surface of the support base. This device allows the cutting and leveling blade to move up and down by rotating an adjusting threaded rod, enabling workers to adjust the height of the cutting and leveling blade according to the thickness of the plastic sheet. This facilitates cutting and leveling the surface of the plastic sheet, thereby increasing the heating effect. Simultaneously, the dust removal and heating integrated structure allows for dust removal pre-treatment of the plastic sheet, reducing the possibility of dust adhering to the heating element surface and enhancing the heating effect of the heating element on the plastic sheet. The device is highly practical.

[0004] The aforementioned embossing pretreatment device for processing PVC flooring uses roller-shaped heating rods to heat the PVC flooring. The heating rollers and PVC flooring are in line contact, resulting in a small contact area. This makes it difficult to achieve a tight fit between the flooring and the rollers, easily leading to gaps. This not only reduces heat transfer efficiency but also prevents some areas of the flooring from being fully heated, affecting the heating effect and indirectly causing embossing defects. Furthermore, its heating mechanism and dust removal mechanism are set up independently, and the coordination between the various structures is not compact enough, resulting in equipment redundancy and a waste of space.

[0005] To address the aforementioned issues, an embossing pretreatment device for processing PVC flooring is proposed. Utility Model Content
