Description
Technical field
The utility model relates to a kind of wire drawing machine for the manufacture of PTFE sewing thread.
Background technology
Polytetrafluoroethylene (PTFE) (Teflon or PTFE), be commonly called as " King ", be by the macromolecular compound of tetrafluoroethylene through being polymerized, there is excellent chemical stability, corrosion resistance, sealing, height lubricate not viscosity, electrical insulating property and good anti-aging endurance.As engineering plastics, can be made into polyfluortetraethylene pipe, rod, band, plate, film etc.PTFE is thermoplastic, but it is difficult to process with the forming method of ordinary thermoplastics, its " unworkability " comes from its special mouldability, the withered degree of the melting as PTFE is large, shear-sensitive, large shrinkage creep properties and low friction factor.
In the operation manufacturing PTFE sewing thread, first need bar-shaped PTFE blank to be processed into the strip silk that diameter is 0.8 ~ 1.5 millimeter, after then these strip silks being carried out drawn down, make PTFE sewing thread.But make PTFE sewing thread after strip silk is carried out drawn down, tradition is generally adopt machinery calendering, manual tension, there is the problems such as labour intensity is large, production efficiency is low, the even thickness of product difference, impact sealing result of use, the mode of production of half machinery, production efficiency is low.Existing mechanical wire-drawing equipment, complicated structure, it is convenient not to use, and the silk thickness of pull-out is uneven, and in drawing process, silk thread easily ruptures, and reduces production efficiency, increases production cost.

Further, before described drawing-off, pressure roller is arranged on the left side of described draw box, and after described drawing-off, pressure roller is arranged on the right side of described draw box.
Further, before described drawing-off, the rotating speed of pressure roller is 68 ~ 72rpm, and after described drawing-off, the rotating speed of pressure roller is 840 ~ 970rpm.
Further, the described oiling roller that removes is set to two.
Further, described oiling roller lower left of removing was provided with line roller.
Further, what be provided with in described sinter box and described draw box that the PTFE silk that holds strip passes through crosses line plate.
Further, the both sides of described sinter box and the both sides of described draw box are provided with deconcentrator.
Operation principle:
During use, the PTFE silk of strip walked around successively line roller, except pressure roller after pressure roller, draw box and drawing-off before oiling roller, sintering equipment, drawing-off, and be wound into dish through coiling swing rod and closed reel.
Because PTFE blank needs aviation kerosine during fabrication, so the PTFE silk ribbon of strip has aviation kerosine, first the PTFE silk of strip carries out oil removing through degreasing unit, under the high temperature of degreasing unit 360 ~ 400 DEG C, kerosene is removed, and is beneficial to the drawing-off of the PTFE silk of follow-up strip, removing kerosene, also can improve the quality of obtained PTFE sewing thread, increase its intensity.
The sintering temperature of sintering equipment is 380 ~ 400 DEG C, high temperature sintering, so that the PTFE silk of follow-up drafting system to strip carries out drawing-off.
Because the rotating speed of pressure roller before drawing-off is lower than the rotating speed of pressure roller after drawing-off, the formation of speed difference reaches the object of drawing-off, and final pull-out meets the requirements of sewing thread, finally by coiler device around on plastics wire spool.
The beneficial effect that the utility model reaches is:
Compared with prior art, the utility model has the advantages that and adopt mechanized equipment that the PTFE silk of strip is pulled into PTFE sewing thread, realize fully-automatic production, structure is simple, easy manufacture, easily use operation, product quality easy to control, reduce labour intensity and human input, enhance productivity, obtained PTFE sewing thread does not rupture, and ensure that the uniformity of PTFE sewing thread, intensity and qualification rate.
Accompanying drawing explanation
