Hot-pressing equipment for composite non-woven fabric

Abstract

The invention discloses hot pressing equipment for a composite non-woven fabric. The hot pressing equipment structurally comprises a machine body, a first guide roller, a first hot-pressing roller, athird guide roller, a composite non-woven fabric winding device, a second hot-pressing roller, a second guide roller, a non-woven fabric roll, an interlayer fabric roll and an inner fabric roll, wherein the non-woven fabric roll, the interlayer fabric roll and the inner fabric roll are sequentially arranged on the machine body. Compared with the prior art, the invention has the following beneficial effects: the contact area of the non-woven fabric and a heating roller can be greatly increased, which is beneficial for improvement of hot pressing efficiency and reduction in hot pressing time; invirtue of magnetism principles and the fact that an air suction ball is pressed to exhaust air and sucks air to realize resetting, the composite non-woven fabric can be adsorbed and clamped, so the composite non-woven fabric is allowed to quickly enter an annular cavity, and the composite non-woven fabric is located in the annular cavity for hot pressing; and heat preservation and insulation areconducted through glass wool, and an inner roller is hidden in an outer roller to prevent the inner roller from being exposed outside, so heat dissipation can be effectively reduced, and hot pressingcompositing of the non-woven fabric is better facilitated.

Description

technical field [0001] The invention relates to the field of non-woven fabric processing, in particular to a composite non-woven fabric hot-pressing equipment. Background technique [0002] Composite non-woven fabric is a new type of packaging material. It can perform multiple composite treatments on non-woven fabrics and other fabrics, such as film coating treatment, hot pressing treatment, glue spray treatment, ultrasonic treatment, etc. Through composite treatment, two layers can be combined. Or three layers of fabrics are combined together to produce products with special functions, such as high strength, high water absorption, high barrier properties, high hydrostatic pressure resistance, etc., which are widely used in medical, health, protection, industry and automotive industries and other fields. [0003] The existing hot pressing method for the composite nonwoven fabric is to pass the composite nonwoven fabric between two hot pressing rollers parallel to each other...

Problems solved by technology

[0003] The existing hot pressing method for the composite nonwoven fabric is to pass the composite nonwoven fabric between two hot pressing rollers parallel to each other in the longitudinal direction, so as to realize the hot pressing of the hot pressing roller on the composite nonwoven fabric. The longitudinal section of the hot pressing roller is circular, so that the contact mode between the composite non-woven fabric and the hot pressing roller is line contact, so that the contact area is small, which will reduce the hot pressing efficiency. At the same time, the heating roller surface of the heating roller is exposed, which is easy Accelerating the heat dissipation of the heating roller will affect the effect of hot pressing
