Description

Technical Field

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

[0002] The PTFE tape needs to be wound up after processing, but during the winding process, the PTFE tape is often directly wound around a winding roller, and then the winding roller rotates to directly wind the PTFE tape. In this way, the PTFE tape is directly subjected to the tension from the winding roller during the winding process. Therefore, the tension generated by the winding roller on the PTFE tape needs to be large enough to make the PTFE tape tightly wound around the winding roller. However, if the tension of the winding roller is too large, the PTFE tape will be easily stretched excessively, resulting in poor quality of the PTFE tape. Utility Model Content

[0030] Reference Figure 1-6 ,

[0031] A polytetrafluoroethylene tape winding device comprises a winding roller, a guide roller and a driving component.

[0032] The winding roller is used to wind the PTFE tape and roll it along a winding track. A guide roller is disposed on the winding track, and the guide roller abuts the PTFE tape on the winding roller. The winding track is the path of the PTFE tape. The drive member is used to drive the winding roller to rotate so that the PTFE tape is received on the winding roller. The drive member is also used to drive the winding roller to move relative to the guide roller. Specifically, as the thickness of the PTFE tape on the winding roller gradually increases, the drive member drives the winding roller to move so that the angle between the line connecting the center point of the winding roller and the center point of the guide roller and the horizontal plane changes within a preset range.

[0033] In this embodiment, the driving member drives the winding roller to rotate, and the driving member may include a motor, which directly drives the winding roller to rotate. The driving member drives the winding roller to move, and the driving member may include a mechanical arm, which directly drives the winding roller to move.

[0034] The purpose of the movement of the winding roller is to make the PTFE tape on the winding roller contact the guide roller. This ensures that the guide roller will apply pressure to the PTFE tape on the winding roller the moment the PTFE tape is wound onto the winding roller, so that the PTFE tape on the guide roller is tightly pressed against the PTFE tape on the winding roller, thus achieving a tight wrapping effect of the PTFE tape. This provides another way to tightly wrap the PTFE tape around the winding roller, avoiding the phenomenon of using a tightening PTFE tape to tightly wrap around the winding roller, which may cause the PTFE tape to be stretched, deformed, or damaged. This not only achieves the goal of tightly wrapping the PTFE tape around the winding roller, but also protects the PTFE tape.

[0035] In some embodiments, the driving member includes a rotating arm and a rotational drive structure: the rotational drive structure is configured to drive the rotating arm to rotate about a fixed axis; the rotating arm is configured to mount the winding roller. In this embodiment, the rotational drive structure may be a motor, which directly drives the rotating arm to rotate. Rotation of the rotating arm thereby causes the winding roller to move.

[0036] Specifically, the driving member further includes: a driving motor and a transmission structure; a mounting slot is formed in the rotating arm; the transmission structure is arranged in the mounting slot; and the driving motor drives the winding roller to rotate through the transmission structure.

[0037] More specifically, the transmission structure includes: a first pulley, a second pulley, a first transmission belt, a first rotating shaft, a first gear, a second gear and a second rotating shaft; the first pulley is fixed to the output end of the drive motor, the first rotating shaft is rotatably connected to the rotating arm, the second pulley and the first gear are both fixed to the first rotating shaft, the second rotating shaft is rotatably connected to the rotating arm, the second gear is fixed to the second rotating shaft, and the second rotating shaft is fixed to the winding roller.

[0038] In other embodiments, the rotational drive structure includes a displacement drive component, a third rotating shaft, and a fixed base. The displacement drive component is selected from the group consisting of a pneumatic cylinder, a hydraulic cylinder, and an electric push rod. The PTFE tape rewinding device further includes a base for mounting the rewinding roller, the guide roller, and the drive element. The fixed base is fixedly mounted on the base, the third rotating shaft is rotatably connected to the fixed base, one end of the displacement drive component is hingedly connected to the base, and the other end is hingedly connected to the rotating arm; the rotating arm is fixed to the third rotating shaft.

[0039] In other embodiments, a support structure is provided on the rotating arm; the support structure is detachably connected to the rotating arm; and the support structure is used to install the second rotating shaft. An arc-shaped groove is formed on the rotating arm; the support structure includes a bearing and a locking component; the bearing is placed in the arc-shaped groove, and the locking component is used to form a fixed locking point at the end of the bearing facing away from the arc-shaped groove. In this embodiment, the locking component is a bolt, which is threadedly connected to the rotating arm. By rotating the bolt, the screw rod of the bolt can be pressed against the outer ring of the bearing, thereby fixing the outer ring of the bearing and enabling the normal operation of the bearing. The fixed locking point is the point where the screw rod abuts against the outer ring of the bearing. When disassembly is required, the bolt is loosened, and the screw rod of the bolt is away from the bearing, thereby facilitating the removal of the bearing.

[0040] In some other embodiments, a fixed frame is provided below the base; a displacement member is provided on the fixed frame, and the base is connected to the fixed frame via the displacement member; the displacement member is used to drive the base to move along the axis of the winding roller. The displacement member is selected from the group consisting of a pneumatic cylinder, a hydraulic cylinder, and an electric push rod.

[0041] Specifically, the driving member is also used to drive the guide roller to rotate. The driving member also includes a power motor, which drives the guide roller to rotate.

[0042] In other embodiments, the driving member includes a main motor and a transmission gearbox. The transmission gearbox has an input end and two output ends, the input end of the transmission gearbox is connected to the output end of the main motor, one of the output ends of the transmission gearbox is connected to the first rotating shaft, and the other output end of the transmission gearbox is connected to the guide rod.

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.
