Abstract
The utility model relates to a stretcher for a polytetrafluoroethylene sealing tape. According to the stretcher, the polytetrafluoroethylene sealing tape is fed by a winding drum shaft of a feeding device so as to enter heating cavities of a heating device; the polytetrafluoroethylene sealing tape is preliminarily heated in the heating cavity 1 and then heated again in the heating cavity 2, and a film is stretched by a stretching roller when the polytetrafluoroethylene sealing tape is heated again; finally, the polytetrafluoroethylene sealing tape is taken out of the heating cavity and reeled by a reeling device, and during the reeling, the film is detected by a sensor on a reeling shaft and the edge consistency of the polytetrafluoroethylene sealing tape is ensured by an edge alignment motor. The whole stretcher is simple to manufacture, low in cost as well as simple and convenient in stretching process. Finally, the polytetrafluoroethylene sealing tape obtained in the stretching manner is good in quality and unlikely to break.
Description
Technical field
The utility model relates to a kind of polytetrafluoroethylraw raw material band process equipment.
Background technology
Polytetrafluoroethylraw raw material band is conventional a kind of assistant product during hot-water heating is installed, and for pipe fitting junction, strengthens the seal of pipeline junction.Raw material band is the desirable encapsulant of a kind of novelty.Due to its nontoxic, tasteless, good sealing, insulating properties, rotproofness, be widely used in the fields such as water treatment, natural gas, chemical industry, plastics, electronic engineering.
Because the thickness of raw material band only has 0.1mm left and right conventionally, so technological requirement is higher in its production process, otherwise cannot reach requirement, also easily there is phenomenon of rupture.
Utility model content
The purpose of this utility model is to provide a kind of stretching-machine for polytetrafluoroethylraw raw material band, for stretch polytetrafluoroethylraw raw material, obtains raw material band, and drawing process is simple and convenient, and raw material band does not rupture.
For reaching this object the utility model by the following technical solutions:
For a stretching-machine for polytetrafluoroethylraw raw material band, comprise the feed arrangement, heater, stretching device and the wrap-up that set gradually;
Described feed arrangement comprises frame, is provided with for placing the spool shaft of polytetrafluoroethylene film in frame;
Described heater comprises heating chamber one and heating chamber two, in heating chamber one, is provided with guide roller, is provided with extension roller in heating chamber two;
Described stretching device comprises drawing plate and tensile axis, and tensile axis is arranged on drawing plate, and tensile axis connects stretching motor;
Described wrap-up comprises rolling frame, is provided with rolling guide roller and Scroll in rolling frame, is provided with the sensor for detection of raw material band on Scroll, and Scroll is connected with opposite side motor.
In described heating chamber two, be provided with 5 extension rollers, be divided into two rows, upper row arranges 3, and lower row arranges 2.
Stretching-machine of the present utility model passes through the spool shaft of feed arrangement by 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 extension roller, film is extended, finally from heating chamber out by 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of stretching-machine for polytetrafluoroethylraw raw material band, comprises the feed arrangement, heater, stretching device and the wrap-up that set gradually; Feed arrangement comprises frame 2, is provided with for placing the spool shaft 1 of polytetrafluoroethylene film in 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 stretching motor; Wrap-up comprises rolling frame 9, is provided with rolling guide roller 10 and Scroll 11 in 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.In heating chamber 24, be provided with 5 extension rollers 6, be divided into two rows, upper row arranges 3, and lower row arranges 2.
Polytetrafluoroethylraw raw material band raw material is placed in 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, in heating chamber 24, be provided with extension roller 6 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 stretches by tensile axis 8, tensile axis 8 is by stretching driven by motor, tensile axis 8 can regulate by stretching motor the intensity of stretching, after stretched, raw material band finally enters wrap-up rolling, when 11 pairs of raw material bands of Scroll carry out rolling, by sensor disposed thereon, detect the edge of raw material band, when edge setting over certain line explanation raw material band of raw material band being detected, deflect away from, at this time just by opposite side motor 12, drive Scroll to adjust, the edge of raw material band is no longer deflected away from, and then proceed rolling, can guarantee the uniformity at raw material band edge like this.
