Problems solved by technology

The existing membrane splitting equipment has a complex structure, is not convenient to use, has high labor intensity for workers, low production efficiency, is easy to break during the shredding process, and the cut wires are uneven. Polytetrafluoroethylene (Teflon or PTFE), commonly known as " "Plastic King" is a high-molecular compound polymerized by tetrafluoroethylene, which has excellent chemical stability, corrosion resistance, sealing, high lubrication and non-stickiness, electrical insulation and good aging resistance, and is used in engineering Plastic, 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 and low friction coefficient, some existing equipments are not thorough enough to crack the film when processing PTFE, which affects the performance of the finished product. At the same time, some existing equipment often breaks during the process of cracking the film, which not only affects production efficiency, but also requires a lot of cost to repair
In addition, the existing membrane-splitting pair has a complex structure, is very inconvenient to use, and has poor membrane-splitting effect
In addition, the steel needles of the existing split film pair are usually fixedly welded on the split film roller. On the one hand, the length of the steel needle cannot be adjusted. On the other hand, once a certain steel needle is tempered, it is extremely inconvenient to maintain.

Abstract

The invention discloses a membrane splitting pair for manufacturing PTFE fibers. The membrane splitting pair comprises two membrane splitting rollers, and the membrane splitting rollers comprise the upper membrane splitting roller and the lower membrane splitting roller which are used in a vertically cooperative mode; a PTFE membrane is arranged between the upper membrane splitting roller and the lower membrane splitting roller; each membrane splitting roller is uniformly and circumferentially provided with a plurality of thorns, the thorns on the upper membrane splitting roller and the thorns on the lower membrane splitting roller are arranged in a staggered mode, and each membrane splitting roller comprises a cavity which is arranged in the middle of the membrane splitting roller and used for being connected with a rotating shaft and a fixed key arranged on one side of the cavity. According to the membrane splitting pair, the structure is simple, use is convenient, the machining efficiency is high, and the PTFE membrane is split into the fibers through cooperation of the upper membrane splitting roller and the lower membrane splitting roller; the thorns on the upper membrane splitting roller and the thorns on the lower membrane splitting roller are arranged in the staggered mode, and therefore the phenomenon that the thorns are broken is prevented.

Description

Technical field [0001] The present invention involves a parts on a fracture film, which is specifically a cracking part of the manufacture of PTFE fiber, which is a technique in the technical field of fracture film machine. Background technique [0002] The membrane cracking equipment is cutting the membrane to obtain a flat narrow wire to prepare for subsequent manufacturing production.The existing membrane cracking equipment has a complicated structure and is not convenient to use. The workers' labor intensity is high, the production efficiency is low, and the shredded process is easy to break and cut out."Plastic King" is a polymer compound formed by the aggregation of tetrafluoroethylene. It has excellent chemical stability, corrosion resistance, sealing, high lubrication non -viscosity, electrical insulation and good anti -aging endurance.Plastic can be made into polytetrafluoroethylene tubes, rods, bands, plates, film, etc.PTFE is a thermoplastic plastic, but it is difficul...
