Fabric laminating machine using PU glue

Abstract

The invention discloses a fabric laminating machine using PU glue. The fabric laminating machine using the PU glue comprises a machine frame, wherein a top fabric uncoiling mechanism, a bottom fabric uncoiling mechanism, a gluing mechanism, a hot pressing mechanism, a dragging mechanism and a coiling mechanism are arranged on the machine frame; the hot pressing mechanism comprises a hot pressing roll and press rolls adhered to the hot pressing roll; oil guiding slots are formed in the hot pressing roll; an oil inlet and an oil returning port are formed in the end surfaces of the two sides of the hot pressing roll respectively; the oil inlet and the oil returning port are connected with oil pipes through rotating connectors; top fabric and bottom fabric are laminated by the hot pressing mechanism, cooled by a cooling device, dragged by the dragging mechanism, counted by a counter, sent into the coiling device and coiled. Through arrangement of winding and scutching rolls, pneumatic deviation-correcting rolls, selvedge uncurlers and the like, the fabric laminating machine corrects deviation, removes creases and performs other pretreatments, so that the levelness of the fabric is improved; the hot pressing roll is filled with heat-conducting oil, and is connected with the oil pipes through the rotating connectors, so that the hot pressing roll is uniformly heated and the laminating quality of the top fabric and the bottom fabric can be improved.

Description

technical field [0001] The invention relates to the field of fabric compounding machines, in particular to a fabric compounding machine using PU glue. Background technique [0002] Composite fabric is a new type of material made by bonding one or more layers of textile materials, non-woven materials and other functional materials. It is suitable for sofas, clothing and other textiles, and is one of the indispensable fabrics for people's home life. . The laminating machine is mainly used for laminating two or more layers of various kinds of cloth, leather, film, paper, sponge, etc. Specifically, it is divided into glue compound and glueless compound, and glue compound is divided into water glue, PU glue, hot melt glue and so on. PU glue is widely used because of its low price. In the compounding process of the PU glue compound machine, after the PU glue is glued, the fabric needs to be laminated and hot-pressed. During the hot-pressing process, the temperature of the press...

AI Technical Summary

Problems solved by technology

In the compounding process of the PU glue compound machine, after the PU glue is glued, the fabric needs to be laminated and hot-pressed. During the hot-pressing process, the temperature of the pressure roller is likely to be uneven, resulting in uneven glue on the compound fabric, which leads to easy fabrics in the later stage. Degumming and other conditions seriously affect the quality of the product

At the same time, during the feeding process of the fabric, the fabric will be transported to the heating laminating mechanism if it is uneven or uneven. Finally, the quality requirements cannot be met, and the fabric will also have defects such as wrinkles
