Film covering device for non-woven fabric production

Abstract

The invention discloses a film covering device for non-woven fabric production. The device comprises a working box, a long groove is formed in the left side of the top of the working box, and a film covering roller is rotationally connected into the long groove. According to the device, through cooperative use of the working box, the long groove, the film covering roller, a heating ring, a rubber extrusion layer, a film covering motor, a pressure roller, a rotating rod, a cutting blade, a cutting groove, a discharging roller and a cutting motor, the problem that in the hot-pressing film covering process of a non-woven fabric, due to the fact that the width of the non-woven fabric is different from that of a pressing roller of the device, the edge of the non-woven fabric is prone to be tilted, so that a material film is prone to fall off from the edge of the non-woven fabric if the tilted edge is not treated is solved, the edge of the non-woven fabric is cut after hot-pressing film covering is completed, the tilted edge generated during film covering is removed, the edge of the non-woven fabric is kept flat, and the material film is prevented from falling off from the edge of the non-woven fabric.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a film-coating device based on the production of non-woven fabrics. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, needle-punched cotton, needle-punched non-woven fabrics, etc., are made of polyester fibers and polyester fibers (PET for short), and are made by acupuncture processes, which can be made in different thicknesses, handles, Hardness etc. Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light and thin, flame-retardant, non-toxic and tasteless, low price, and recyclable. It can be used in different industries, such as sound insulation, heat insulation, electric heaters, masks, clothing, medical, filling materials, etc. [0003] In the production process of non-woven fabrics, the toughness and strength of non-woven fabrics can be improved by coating the surface of non-woven fabrics. When coa...

AI Technical Summary

Problems solved by technology

[0003] In the production process of non-woven fabrics, the toughness and strength of non-woven fabrics can be improved by coating the surface of non-woven fabrics. When coating non-woven fabrics, it is necessary to bond non-woven fabrics and material films for hot pressing Make it shape, but in the process of hot-pressing the non-woven fabric, due to the gap between the width of the non-woven fabric and the pressure roller of the device, it is easy to cause warping on the edge of the non-woven fabric. Handling tends to cause the material film to detach from the edge of the non-woven fabric
