Description

Technical Field

[0001] The present application relates to the YYLY field, and in particular to a PTFE tape puncture and winding 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 weaving, the PTFE tape needs to be sintered and punctured at high temperature, which will make the wear resistance of the PTFE tape higher after weaving. However, the puncture of the PTFE tape often causes the PTFE tape to be transported intermittently. When the PTFE tape stops, multiple needles are used to pierce and puncture the PTFE tape from top to bottom. In this way, the intermittent transportation of the PTFE tape will greatly affect the processing speed of the PTFE tape. Utility Model Content

[0034] Reference Figure 1-6 ,

[0035] A polytetrafluoroethylene tape puncture winding device comprises a winding component, an abutment wheel, a puncture needle row and a driving component.

[0036] The winding assembly is used to convey and rewind the PTFE tape along a winding direction. Two abutment wheels are provided, one at the upper and one at the lower end of the PTFE tape. Multiple rows of puncture needles are provided, evenly distributed around the circumference of the abutment wheels and fixed to the abutment wheels. A drive member is used to rotate the abutment wheels. The rows of puncture needles on the abutment wheels abut against the PTFE tape and puncture the tape.

[0037] In this example, the winding assembly uses existing technology, mainly a winding roller for winding and a rotating motor that drives the winding roller to rotate. The hardness of the PTFE tape itself is relatively poor. In order to improve the hardness of the PTFE tape, the PTFE tape needs to be sintered at high temperature first. After the PTFE tape is sintered at high temperature, the PTFE tape is punctured to increase the hardness of the PTFE tape. Therefore, the puncture winding device of this application is applied to the PTFE tape after high-temperature sintering. The needle row on the abutment wheel rotates to puncture the PTFE tape, so that the PTFE tape can be punctured continuously, and the density of the puncture holes in the PTFE tape is uniform, which better ensures the hardness of the PTFE tape is improved.

[0038] In some embodiments, the puncture and rewinding device further includes: a transmission member, which is arranged between the abutment wheel and the rewinding assembly; a friction portion and a puncture needle portion are formed on the transmission member and can move directly or indirectly along the rewinding direction.

[0039] Regarding one of the transmission member solutions, the transmission member includes: a rotating wheel; the driving member is further used to drive the rotating wheel to rotate along the winding direction; the friction portion and the puncture needle portion are each provided in plurality, and are arranged adjacent to each other on the circumference of the rotating wheel. Therefore, the rotation of the rotating wheel can cause the friction portion and the puncture needle portion to contact different positions of the PTFE tape as the PTFE tape is transported, thereby performing a secondary puncture on the PTFE tape, ensuring the density of the puncture holes and improving the hardness of the PTFE tape. The friction portion is used to increase the friction between the PTFE tape and the PTFE tape, preventing the friction portion from contacting the PTFE tape when the PTFE tape relaxes due to stretching, thereby preventing the PTFE tape from shifting relative to the rotating wheel and affecting the puncture effect.

[0040] Regarding another embodiment of the transmission member, the transmission member includes a transmission belt; the driving member is further configured to drive the transmission belt in the winding direction; and a plurality of friction portions and a plurality of puncturing portions are provided, each of which is adjacent to each other on the transmission belt. The transmission of the transmission belt also ensures that the puncturing portions are in uniform contact with the PTFE tape.

[0041] The friction part is a plate with a rough surface.

[0042] Specifically, the linear speed of the rotating wheel rotating along the winding direction matches the winding speed of the winding device.

[0043] Specifically, the speed at which the transmission belt is conveyed along the winding direction matches the speed at which the winding device winds up.

[0044] Specifically, the puncture and reeling device further includes: a protective cover; the protective cover is used to form a protective chamber capable of accommodating part of the transmission member.

[0045] Specifically, the puncture and rewinding device further includes a first guide member and a second guide member; the first guide member is used to form a first guide area for guiding the PTFE tape into the drive wheel, and the second guide member is used to form a second guide area for guiding the PTFE tape into the transmission member. Both the first guide member and the second guide member are guide wheels that abut against the PTFE tape.

[0046] Specifically, the puncture and winding device also includes: a pressure roller; the rotating wheel is arranged between the pressure roller and the second guide member; the pressure roller is used to form a third guide area; the second guide area and the third guide area are used to make the polytetrafluoroethylene tape and the rotating wheel form a contact arc surface.

[0047] Specifically, the driving member is a plurality of driving motors, one of which is used to drive the abutment wheel to rotate, and another one of which is used to drive the transmission member to operate.

[0048] The above description is only an illustration of some preferred embodiments of the present disclosure and the technical principles used. 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 the 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.
