Composite cloth preparing equipment

Abstract

The invention belongs to the technical field of textile preparation and discloses composite cloth preparing equipment which comprises a granulating part for preparing activated carbon particles and acoating part, wherein the coating part coats nylon cloth and non-woven fabric into the composite cloth and comprises a cloth winding and unwinding roller forming the first feeding side of the coatingpart, a non-woven fabric winding and unwinding roller forming the second feeding side of the coating part, an input table for bearing activated carbon particles stacked on the discharging side of thegranulating part and forming the third feeding side of the coating part, a nylon cloth gumming component, a non-woven fabric gumming component, a pair of hot pressing rubber rollers and a winding roller, wherein the hot pressing rubber rollers carry out press fit on the gummed nylon cloth and the gummed non-woven fabric to form the composite cloth; the winding roller is used for winding the composite cloth, belongs to a driving roller and forms the discharging side of the coating part; and the activated carbon particles stacked on the input table directly faces the connecting surface of the gummed nylon cloth and are pasted to the connecting surface of the nylon cloth during the preparation process. composite cloth preparing equipment can realize automatic operation during the entire preparing process and accelerates the production efficiency.

Description

technical field [0001] The invention relates to the technical field of textile preparation, in particular to composite cloth preparation equipment. Background technique [0002] At present, several main process characteristics of composite cloth for medical and sanitary materials: Laminating: This technology is the most used method by domestic enterprises. Features: The process is simple, mature, and the production speed is fast (about 100m / min). However, the coating cannot be used as a product that requires ventilation; it feels hard and has poor comfort; it has higher requirements for non-woven fabrics. Non-woven fabrics with low grammage (below 18gsm) and low coating weight (below 15gsm) are not ideal for coating, because the unevenness of the surface of the roll makes the coating process prone to leaks. Hot rolling: It is a standard process for manufacturing SMS non-woven fabrics in two steps. Many domestic enterprises use this process for composite manufacturing of fil...

Problems solved by technology

Disadvantages: large investment in equipment (the cost of a set of 1600mm effective width hot melt adhesive breathable coating composite hot melt adhesive system is more than 400,000 US dollars); the grammage of glue coating is high (composite requirements with an angle of 180 о and a strength of 3.0N / inch For example, the amount of glue used is 4gsm or above); the coating head needs to be in contact with the coating material during coating, which requires high stability and flatness of the winding and unwinding equipment; the coating process exerts relatively high tension on the material Large, while non-woven fabrics and films are required to run under a state of small tension, otherwise it is easy to cause stretching deformation of the material, and the product will wrinkle after compounding, thereby affecting the quality of the product; the operation adjustment is more complicated: non-woven fabrics and films None of them can withstand high temperatures, and the use temperature of hot melt adhesives is basically 150 degrees Celsius or above. Low-speed operation may easily cause the material to be scalded, causing production to stop and waste to increase.
