Production and processing technology of TPU high-low temperature film

Abstract

The invention relates to the technical field of processing of TPU high-low temperature film composite cloth, in particular to a TPU high-low temperature film production and processing technology which is executed through production and processing equipment, the production and processing equipment comprises a rack and a self-locking device, the rack comprises a feeding barrel, a glue coating roller, a receiving barrel and a rotation driving assembly, and the self-locking device is arranged on the rack; the feeding barrel, the glue coating roller and the receiving barrel are rotatably mounted on the rack, the rotary driving assembly is fixedly mounted on the rack, the self-locking device comprises a first mounting frame, a lock catch, lock teeth, a rolling shaft and a first roller, the first mounting frame is rotatably mounted on the rack, the lock catch is fixedly arranged on the first mounting frame, the lock teeth are fixedly arranged on the feeding barrel, and the rolling shaft is fixedly arranged on the first roller. The rolling shaft is fixedly arranged on the machine frame, and the first roller is connected to the rolling shaft in a sleeved mode. According to the automatic locking and stopping device, the function of automatic locking and stopping of the feeding barrel when equipment stops running is achieved, and the defects that after the equipment is suspended, the feeding barrel continues to rotate due to inertia, raw materials are too loose and hung on other objects, and the quality of the raw materials is affected are overcome.

Description

technical field [0001] The invention relates to the technical field of processing TPU high and low temperature film composite cloth, in particular to a production and processing technology of TPU high and low temperature film. Background technique [0002] The high and low temperature film is mainly composed of polyurethane material (TPU) and protective film. Because of its simplicity, softness, elasticity, three-dimensional (thickness), and convenient use, it is widely used in various textile fabrics such as shoe materials, clothing, luggage, etc. It is one of the preferred materials for fashion leisure and sports brands. However, the toughness of the existing high and low temperature membrane structure is too poor, resulting in a short service life. [0003] To this end, Chinese patent CN201910012493.3 discloses a reflective high and low temperature film and a preparation method thereof. The reflective high and low temperature film, by arranging several hemispherical mirr...

Problems solved by technology

[0004] However, in the production process of the existing high and low temperature membrane production and processing equipment, it is easy to have unfavorable conditions such as twisting, hanging, overlapping, missing corners, etc., resulting in the production of high and low temperature membranes that cannot meet the expected quality, and there are too many defective products , leading to an increase in production costs, so there is an urgent need for a production and processing technology of TPU high and low temperature films and corresponding production and processing equipment
