Abstract

The invention discloses a film drafting device used for manufacturing a PTFE sewing thread. The film drafting device comprises a film drafting front pressing roller set, a film drafting drying oven, a film drafting cooling roller set and a film drafting rear pressing roller set which are sequentially arranged from left to right. The film drafting front pressing roller set comprises first guide rollers and a first pressing roller arranged on one first guide roller; the film drafting drying oven comprises an upper drying oven body and a lower drying oven body which are each internally provided with a heating mechanism; the film drafting cooling roller set comprises a cooling box, and cooling rollers and a cooling mechanism are arranged in the cooling box; the film drafting rear pressing roller set comprises second guide rollers and a second pressing roller arranged on one second guide roller. The rotating speed of the first guide rollers is lower than that of the second guide rollers. The film drafting device is simple in structure and easy to manufacture, use and operate, reduces labor intensity and labor input, and improves production efficiency and ensures uniformity, strength and the yield of the PTFE sewing thread, product quality is easy to control, and the drafted film is uniform.

Description

technical field [0001] The invention relates to a film drafting device for manufacturing PTFE sewing thread. Background technique [0002] Polytetrafluoroethylene (Teflon or PTFE), commonly known as the "King of Plastics", is a polymer compound formed by polymerization of tetrafluoroethylene, which has excellent chemical stability, corrosion resistance, sealing, high lubrication and non-stick properties, electrical Insulation and good aging resistance. Used as engineering plastics, it can be made into PTFE tubes, rods, strips, plates, films, etc. PTFE is a thermoplastic, but it is difficult to process with ordinary thermoplastic molding methods. Its "difficulty in processing" comes from its special formability, such as PTFE's large melting dryness, shear sensitivity, and large shrinkage. Creep resistance and low coefficient of friction. [0003] In the process of manufacturing PTFE sewing thread by the film splitting method, firstly, the prepared PTFE wide film blank need...
