Be provided with 5 extension rollers in described heating chamber two, be divided into two rows, upper row arranges 3, and lower row arranges 2.
A kind of drawing process of polytetrafluoroethylraw raw material band, the method comprises the following steps:
1. polytetrafluoroethylene film is arranged on the spool shaft of feed arrangement;
2. by guide roller, polytetrafluoroethylene film is sent into to the interior preliminary heating of heating chamber one of heater;
3. preliminarily heated polytetrafluoroethylene film is sent into to heating again in heating chamber two, by the extension roller, film is extended in heating chamber two simultaneously;
4. will introduce in stretching device and be stretched through the polytetrafluoroethylene fibre film of heating, the tensile axis in stretching device connects the stretching motor, by the stretching motor, regulates hot strength;
5. stretched polytetrafluoroethylene film is carried out to rolling with the Scroll of wrap-up, be provided with the sensor for detection of raw material band on Scroll, Scroll is connected with the opposite side motor.
Be provided with 5 extension rollers in described heating chamber two, be divided into two rows, upper row arranges 3, and lower row arranges 2.
Stretching-machine of the present invention passes through the spool shaft of feed arrangement by the polytetrafluoroethylraw raw material band charging, enter in the heating chamber of heater, first in the interior preliminary heating of heating chamber one, then enter heating again in heating chamber two, when again heating, by the extension roller, film is extended, finally from heating chamber out by the wrap-up rolling, in the time of rolling, on Scroll, by sensor, film is detected, and by the uniformity at opposite side motor assurance raw material band edge, whole equipment making is simple, cost is lower.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of stretching-machine for polytetrafluoroethylraw raw material band, comprise the feed arrangement, heater, stretching device and the wrap-up that set gradually; Feed arrangement comprises frame 2, is provided with the spool shaft 1 for placing polytetrafluoroethylene film on frame 2; Heater comprises heating chamber 1 and heating chamber 24, is provided with guide roller 5 in heating chamber 1, is provided with extension roller 6 in heating chamber 24; Stretching device comprises drawing plate 7 and tensile axis 8, and tensile axis 8 is arranged on drawing plate 7, and tensile axis 8 connects the stretching motor; Wrap-up comprises rolling frame 9, is provided with rolling guide roller 10 and Scroll 11 on rolling frame 9, is provided with the sensor for detection of raw material band on Scroll 11, and Scroll 11 is connected with opposite side motor 12.Be provided with 5 extension rollers 6 in heating chamber 24, be divided into two rows, upper row arranges 3, and lower row arranges 2.
The polytetrafluoroethylraw raw material band raw material is placed on spool shaft 1, by the axis of guide, enter in heating chamber 1, raw material band is tentatively heated heating chamber 1 is interior, raw material band enters in heating chamber 24 in heating chamber 1 by guide roller 5, interior to further raise temperature heating of raw material band at heating chamber 24, be provided with extension roller 6 in heating chamber 24 simultaneously, extension roller 6 has 5, be divided into two rows, above 3, below 2, raw material band passes through the extension of two rows extension roller 6 in the interior further heating of heating chamber 24 again, raw material band after heat treated out enters afterwards stretching device, raw material band is stretched by tensile axis 8, tensile axis 8 is by the stretching driven by motor, tensile axis 8 can be regulated by the stretching motor intensity of stretching, after stretched, raw material band finally enters the wrap-up rolling, when 11 pairs of raw material bands of Scroll carry out rolling, detect the edge of raw material band by sensor disposed thereon, when the edge that raw material band detected setting over certain line explanation raw material band deflects away from, at this time just by opposite side motor 12, driving Scroll is adjusted, make the edge of raw material band no longer deflect away from, and then proceed rolling, can guarantee the uniformity at raw material band edge like this.
