Description

Technical Field

[0001] The present application relates to the field of polytetrafluoroethylene tape processing, and in particular, to a polytetrafluoroethylene high-temperature sintering processing device. Background Art

[0002] The wear resistance of PTFE tape after weaving is very high, and PTFE tape is generally used after weaving.

[0003] Before the PTFE tape is woven, it needs to be sintered and punctured at high temperature, which will make the wear resistance of the PTFE tape higher. However, when the PTFE tape is sintered at high temperature, it is often transported in a straight line directly through a heating chamber. In order to make the PTFE tape stay in the heating chamber for a longer time to ensure the effect of high-temperature sintering, the conveying speed of the PTFE tape is generally reduced, so that the PTFE tape passes through the heating chamber slowly, which will cause the PTFE tape to sinter slowly and affect the overall PTFE tape processing speed.

[0009] Furthermore, a support frame is arranged in the accommodating chamber, and the support frame forms a plurality of abutting ends, and the plurality of abutting ends abut against the inner wall surface of the accommodating chamber.

[0010] Furthermore, a socket is formed in the support frame, a plurality of heating tubes are arranged in the heating box, and the heating tubes are inserted into the socket.

[0011] Furthermore, the sintering assembly also includes a pricking roller, a connecting arm and a transmission member; the pricking roller and the guide roller are both installed on the connecting arm, and the driving member rotates the pricking roller and the guide roller through the transmission member; the driving member is also used to drive the connecting arm to rotate so that one of the pricking roller or the guide roller contacts the polytetrafluoroethylene tape; a plurality of pricking needles are arranged on the edge of the pricking roller; the number of the pricking rollers matches the number of the guide rollers.

[0012] Furthermore, the diameter of the pricking roller is smaller than the diameter of the guide roller; when the pricking roller contacts the polytetrafluoroethylene tape, a passage gap for the polytetrafluoroethylene tape to pass through is formed between two adjacent guide rollers, and the passage gap matches the thickness of the polytetrafluoroethylene tape.

[0015] The beneficial effect of the present application is that: by using multiple guide rollers, the length of the polyfluoro tape in the heating chamber is made greater than the circumference of any surface of the heating chamber.

[0038] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0039] Reference Figure 1-12 ,

[0040] A polyfluoroethylene high-temperature sintering processing device comprises a winding component, a sintering component and a piercing component.

[0041] The winding assembly is used to convey and wind up the polytetrafluoroethylene tape along the winding direction. The sintering assembly forms a heating chamber that can allow the polytetrafluoroethylene tape to pass through and heat the polytetrafluoroethylene tape at high temperature. The puncturing assembly forms a plurality of puncture needles that can pass through the polytetrafluoroethylene tape and puncture the polytetrafluoroethylene tape after passing through the heating chamber. In this embodiment, the winding assembly includes a bracket, a winding roller and a winding motor. The winding motor is mounted on the bracket. The winding roller is rotatably mounted on the bracket. The winding motor is used to drive the winding roller to rotate. The rotation of the winding roller can wind up the polytetrafluoroethylene tape. A packing braiding machine is arranged between the winding assembly and the puncturing assembly. The packing braiding machine is used to braid the polytetrafluoroethylene tape after being processed by the sintering assembly and the puncturing assembly.

[0042] Wherein, the sintering assembly includes a plurality of guide rollers, and the polytetrafluoroethylene tape is wound on the plurality of guide rollers so that the length of the polytetrafluoroethylene tape in the heating chamber is greater than the circumference of any surface of the heating chamber. Through this arrangement, the polytetrafluoroethylene tape can be bent multiple times in the heating chamber, so that more polytetrafluoroethylene tapes can be accommodated in a limited space, so that the polytetrafluoroethylene tape can pass through the heating chamber for a longer time, so that the heating time of the polytetrafluoroethylene tape can be greatly improved in a limited space, the polytetrafluoroethylene tape can be sintered at a high temperature better, and the normal conveying speed of the polytetrafluoroethylene tape can be guaranteed at the same time.

[0043] Specifically, the sintering assembly also includes: a heating box and a driving member; the heating box is used to form the heating chamber, and the heating box is provided with an inlet for the polyfluoro tape to enter and an outlet for the polyfluoro tape to be output; the driving member is used to drive the multiple guide rollers to rotate, so that the multiple guide rollers drive the polyfluoro tape to move. In this embodiment, the driving member is a motor, and the driving member directly drives the guide rollers to rotate. The rotation of the guide rollers can transport the polyfluoro tape, so that multiple drives are set in the transmission process of the polyfluoro tape, which can effectively prevent the polyfluoro tape from being stretched and deformed.

[0044] Specifically, the puncture assembly includes: a rotating wheel and a plurality of needle rows arranged on the rotating wheel; the plurality of needle rows are distributed in a circular array on the rotating wheel, and the needle rows are fixed to the rotating wheel. The puncture assembly also includes: pressure rollers, the pressure rollers are arranged in two groups; the rotating wheel is arranged between the two groups of pressure rollers; the axis of the pressure rollers is arranged below the axis of the rotating wheel; and two pressure rollers are arranged in each group.

[0045] More specifically, a receiving chamber connected to the heating chamber is provided in the guide roller. The distance between the outer wall of the guide roller and the inner wall of the receiving chamber is 0.5-1 cm. The receiving chamber in the guide rollers of the same specification makes the guide roller a hollow roller body, so that the guide roller is easier to heat up, and the polytetrafluoroethylene belt in contact with the guide roller can also be affected by the guide roller and heated by the high temperature of the guide roller, thereby ensuring that every position of the polytetrafluoroethylene belt can be heated by the same high temperature, which not only improves the effect of high-temperature sintering of the polytetrafluoroethylene belt, but also improves the uniformity of high-temperature sintering, and better ensures the wear-resistant quality after packing.

[0046] In some embodiments, a support frame is provided in the accommodating chamber, and the support frame forms a plurality of abutting ends, and the plurality of abutting ends abut against the inner wall surface of the accommodating chamber. Preferably, the support frame is a heat-conducting material. In this way, the wall thickness of the guide roller can be reduced to a very low level, and the guide roller is supported by the abutting end of the support frame to prevent the guide roller from being deformed. The thinner the wall thickness of the guide roller, the easier it is for the guide roller to heat up, so that the guide roller can heat up faster to the same temperature as the temperature in the heating chamber, thereby reducing the time required for the initial heating of the guide roller, reducing the initial preparation time when using it, and being able to be put into use faster, and further enhancing the effect of high-temperature sintering, which not only saves energy but also improves the quality of the product.

[0047] In other embodiments, a plug hole is formed in the support frame, and a plurality of heating tubes are arranged in the heating box, and the heating tubes are inserted into the plug hole. The heating tube support is placed in the accommodating chamber, so that the guide roller can be heated more quickly.

[0048] In some other embodiments, the sintering assembly further includes a piercing roller, a connecting arm and a transmission member. The piercing roller and the guide roller are both mounted on the connecting arm, and the driving member rotates the piercing roller and the guide roller through the transmission member. The driving member is also used to drive the connecting arm to rotate so that one of the piercing roller or the guide roller contacts the polytetrafluoroethylene tape. A plurality of piercing needles are arranged on the edge of the piercing roller; the number of the piercing rollers matches the number of the guide rollers.

[0049] In this embodiment, the driving member includes a first driving motor and a second driving motor. The output end of the first driving motor is fixed to the connecting arm, and the first driving motor is used to drive the connecting arm to rotate. The second driving motor is installed next to the connecting arm, and the output end of the second driving motor drives the guide roller and the piercing roller to rotate simultaneously through a transmission member, and the transmission member is one of a gear transmission, a chain transmission and a belt transmission. In this embodiment, the preferred transmission member is a gear transmission, so that the output end of the second driving motor drives the guide roller and the piercing roller to rotate simultaneously through a gear transmission, and the first driving motor drives the connecting arm to rotate, and can switch the guide roller to contact with the polytetrafluoroethylene belt or switch the piercing roller to contact with the polytetrafluoroethylene belt. When the piercing roller contacts the polytetrafluoroethylene belt, it is possible to heat the polytetrafluoroethylene belt at high temperature and pierce holes at the same time, so that the area of ​​the polytetrafluoroethylene belt in contact with the high-temperature air in the heating chamber can be increased, thereby further improving the speed of high-temperature heating of the polytetrafluoroethylene belt, thereby improving the speed of high-temperature sintering.

[0050] Specifically, the first drive motor and the second drive motor are both installed in the heating box, and the transmission member includes an internal gear, a first gear and a second gear. The second drive motor drives the internal gear to rotate, and the internal gear is rotatably connected to the heating box, and the central axis of the internal gear coincides with the central axis of the output end of the first drive motor. The first gear is fixed to the piercing roller, and the second gear is fixed to the guide roller. The first gear and the second gear are both meshed with the internal gear.

[0051] Specifically, the diameter of the piercing roller is smaller than the diameter of the guide roller; when the piercing roller contacts the PTFE tape, a clearance is formed between two adjacent guide rollers for the PTFE tape to pass through, and the clearance matches the thickness of the PTFE tape. When the piercing roller contacts the PTFE tape, the piercing roller pierces the PTFE tape, and the guide roller also contacts the PTFE tape, and the guide roller can also rotate, so that the guide roller provides a driving force for the PTFE tape to move in the heating chamber, thereby better ensuring that the PTFE tape is conveyed in a normal state, avoiding the situation where the PTFE tape in the heating chamber is easily stretched due to the winding assembly providing drive for winding the PTFE tape, thereby better ensuring the heating speed of the PTFE tape and the normal conveying speed of the PTFE tape, and better improving the quality of the PTFE tape after high-temperature sintering.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
