Description

Technical Field

[0001] The utility model relates to the technical field of fabric gluing test, in particular to fabric gluing composite TPU film test equipment. Background Art

[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 making textiles such as sofas and clothing. It is one of the indispensable fabrics for people's home life. It is specifically divided into adhesive composite and adhesive-free composite. Adhesive composite is further divided into water-based adhesive, PU adhesive, hot melt adhesive, etc. Among them, PUR adhesive is widely used in high-end composite fabrics because of its environmental protection. In the actual gluing process, according to different needs, a TPU film layer needs to be set between the fabric and the PUR adhesive to increase the performance of the composite fabric and the adhesion strength of the PUR adhesive.

[0003] In the existing fabric gluing composite TPU film integrated test equipment, the fabric gluing test process is often carried out in a step-by-step manner, that is, the PUR rubber roller gluing process and the TPU film layer coating PUR glue process. The TPU film layer coating PUR glue process often adopts a roller coating method. The single roller coating amount is limited, and the gram weight error of different gluing times is large. At the same time, the gluing strength of the roller coating form is low, which makes the PUR glue penetrate into the fabric and the fiber depth of the TPU film layer shallow, that is, the anti-peeling strength is weak, which ultimately makes the result of the fabric gluing test have a large deviation.

[0004] Therefore, it is necessary to invent a fabric glue composite TPU film testing equipment to solve the above problems. Utility Model Content

At the same time, the gluing strength of the roller coating form is low, which makes the PUR glue penetrate into the fabric and the fiber depth of the TPU film layer shallow, that is, the anti-peeling strength is weak, and ultimately makes the result of the fabric gluing test have a large deviation.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

An unwinding guide roller that can transport the fabric is rotatably arranged between the fabric unwinding side and the trimming device of the unwinding rack, and the integrated control panel is arranged above the front cooling table.

[0009] As a preferred solution of the utility model, the TPU film casting device includes a dehumidification and drying device that can dehumidify and dry TPU film particles, a screw plasticizing device installed below the dehumidification and drying device and can perform high-temperature plasticization treatment on the TPU film particles, a flow channel tube installed at the right end of the screw plasticizing device and through which the plasticized TPU film particles can flow, a filter assembly arranged in the flow channel tube, and a casting mold installed at the bottom end of the flow channel tube.

[0011] As a preferred solution of the utility model, the cooling component includes a rear cooling table and a material storage rack from left to right, and the rear cooling table can cool the fabric coated with PUR glue.

[0012] As a preferred solution of the utility model, a winding guide roller is rotatably provided at the left end of the winding frame, and the winding guide roller is arranged between the material storage rack and the winding frame.

At the same time, the slit extrusion die has a larger spraying intensity, which increases the gluing intensity, allowing the PUR glue to penetrate deeper into the fabric and the fiber of the TPU film layer, thereby increasing the anti-peeling strength and ultimately weakening the deviation of the results of the fabric gluing test. The main control interface in the integrated control panel is used to coordinate and control the winding control interface, the TPU film casting control interface and the PUR gluing control interface, so that the PUR glue gluing process and the TPU film layer coating PUR glue process are carried out simultaneously, so as to carry out a continuous gluing test on the fabric.
