Description

Technical Field

[0001] The utility model relates to anti-skid cloth production equipment, in particular to a TPE anti-skid cloth multi-layer production line. Background Art

[0002] Elastic anti-slip cloth is used in the molding of plastic products. It can be used for compression molding and multi-layer molding. It is widely used in life. The anti-slip layer on the surface of trays used in restaurants, cafes, hot pot restaurants, buffet restaurants and other places can all be made of elastic anti-slip cloth.

[0003] The existing elastic anti-skid fabric production line is mainly extruded by a plastic extruder, and shaped by a calender to obtain a sheet, and then coated with glue, and then pressed and dried to obtain a finished product. For example, the patent publication number CN102642313A discloses a rubber sheet lamination production line and a method for producing sheets, the production line mainly includes an L-type extruder, a 1# calender, a 1# stretching machine, a coating machine, a laminating device, a joint machine, a film buffer device, a 2# stretching machine, a 2# calender, and a winding device, and these devices are arranged in sequence; the preparation method mainly adopts a conveying winding method for lamination, wherein the laminating device includes a 1# conveyor belt, a 1# cutter, a 2# conveyor belt, a 2# cutter, a 2# pressing roller, a 1# pressing roller and a transmission system, and the continuous preparation of multi-layer rubber composite sheets is achieved by alternately winding and conveying two sets of conveyor belts in the laminating device.

[0004] In the above patent, the film formed by extrusion and calendering by an extruder is stretched, coated and then roll-laminated. It not only needs to rely on glue for lamination, but the multi-layer film products made with glue have low strength and are easy to break. The tensile strength of each part is affected by the uniformity of glue coating, and there will be certain differences. In addition, the finished sheet is difficult to recycle. In addition, it needs to be pressed by a lamination device, which is prone to breakage during pressing, which will also cause the production line to be too long and increase costs.
