Description

Technical Field

[0001] This utility model relates to the field of polytetrafluoroethylene (PTFE), and in particular to a device for roller pressing and shaping recycled PTFE strips. Background Technology

[0002] An existing patent (publication number: CN105479647B) discloses a shaping device for recycled polytetrafluoroethylene (PTFE) strips. It includes a machine base with a hot pressing mechanism on the base, comprising a frame supported on the machine base, a pressure roller assembly rotatably connected to the frame, and a heating device for heating the pressure roller assembly. The pressure roller assembly includes an upper pressure roller and a lower pressure roller, which are arranged parallel to each other with the roller surface of the upper pressure roller pressed against the roller surface of the lower pressure roller. The hot pressing mechanism has an unwinding mechanism on one side and a winding mechanism on the other. The unwinding mechanism includes a support and a driven shaft rotatably connected to the support. The winding mechanism includes a reel and a drive device for rotating the reel. However, this device, which states that "the pressure roller assembly includes an upper pressure roller and a lower pressure roller," relies on the upper and lower pressure rollers inside the frame for roll forming. Because the upper and lower pressure rollers are located inside the frame, damage to either roller may prevent timely replacement, affecting the equipment's maintenance efficiency. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing a PTFE recycled material strip roll forming device that uses two sets of pressure rollers at the front of a frame to roll and shape the strip. If a pressure roller is damaged, rotating the hexagonal head on the side of the first roller frame moves the positioning pin clamping block and simultaneously pulls out the pin inside the pin slot, thereby releasing the pin from locking the second positioning plate on the side of the pressure roller. This allows the pressure roller to be removed from the equipment for quick replacement, thus increasing the equipment's maintenance efficiency.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A roll forming device for recycled polytetrafluoroethylene (PTFE) strip includes a base, a column, a double-threaded rod, a hexagonal head, a positioning pin clamp, a second roller frame, and a pressure roller. The base has a connecting platform on its side. The upper part of the base is fixedly connected to the column. The upper part of the column is fixedly connected to a frame. The front part of the frame is fixedly connected to a cylinder frame. The cylinder frame has a guide groove on its side. The upper part of the lifting frame has a guide rod. The lifting frame is adapted to the guide rod and is connected to it. The guide rod slides inside the lifting frame. The upper part of the guide rod has a limit. The front part of the cylinder frame is fixedly connected to a cylinder. The lower part of the cylinder is fixedly connected to the lifting frame. The lifting frame has a cantilever on its side. The front part of the column and the lower part of the cantilever are both fixedly connected to a first roller frame. The rear part of the first roller frame has a screw shaft groove adapted to the double-threaded rod. The screw shaft groove is connected to the double-threaded rod, and the double-threaded rod rotates inside the screw shaft groove.

[0006] The double-threaded rod is fixedly connected to the hexagonal head on the side, and the double-threaded rod has a screw thread on the side. The first roller frame is fixedly connected to the first positioning plate on the side. The first positioning plate is adapted to the positioning pin clamping block. The first positioning plate is connected to the positioning pin clamping block, and the positioning pin clamping block slides on the side of the first positioning plate. Beneficial effects

[0007] 1. In the operation of this utility model, the recycled PTFE strip roll forming device uses two sets of pressure rollers at the front of the frame to roll and form the recycled PTFE strip. If the pressure roller is damaged, the hexagonal head on the side of the first roller frame is rotated, which moves the positioning pin clamping block and pulls out the pin inside the pin groove. This releases the pin from the second positioning plate on the side of the pressure roller, allowing the pressure roller to be removed from the equipment for quick replacement, thereby increasing the maintenance efficiency of the equipment.

[0008] 2. During the use of this utility model's PTFE recycled material strip roller pressing and shaping device, the PTFE recycled material strip is roller pressed and shaped by two sets of pressure rollers at the front of the frame. Together with the two sets of positioning pins on the side of the first roller frame, they drive the pins to lock the second positioning plate, thereby locking the second roller frame on both sides of the pressure roller. This prevents the first roller frame from bending and jamming due to unilateral force, thus increasing the stability of the equipment.

[0009] 3. During the use of the PTFE recycled material strip roller pressing and shaping device of this utility model, the cylinder on the upper part of the cylinder frame adjusts the first roller frame at the lower part of the lifting frame by lifting and lowering, and the guide rod on the side of the lifting frame guides the lifting frame, so that the cylinder keeps both sides of the lifting frame synchronized during lifting and lowering, avoiding the cylinder deformation and jamming caused by the lifting frame being subjected to force on one side, thereby further increasing the stability of the equipment.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0019] Example 1:

[0020] A roll forming device for recycled polytetrafluoroethylene (PTFE) strip includes a base 01, a column 03, a double-threaded rod 14, a hexagonal head 16, a positioning pin clamp 18, a second roller frame 22, and a pressure roller 24. The base 01 has a connecting platform 02 on its side. The upper part of the base 01 is fixedly connected to the column 03, and the upper part of the column 03 is fixedly connected to a frame 04. The front part of the frame 04 is fixedly connected to a cylinder frame 05. The cylinder frame 05 has a guide groove 06 on its side. A lifting frame 07 has a guide rod 08 on its upper part. The lifting frame 07 is adapted to the guide rod 08 and is connected to the guide rod 08. The guide rod 08 slides inside the lifting frame 07. During use, the roll forming device for recycled PTFE strip uses a cylinder 10 on the upper part of the cylinder frame 05 to press the lower part of the lifting frame 07. The first roller frame 12 is adjusted for lifting and lowering, and works with the guide rod 08 on the side of the lifting frame 07 to guide the lifting frame 07, so that the cylinder 10 keeps both sides of the lifting frame 07 synchronized during lifting and lowering, avoiding the deformation and jamming of the cylinder 10 caused by the lifting frame 07 being subjected to force on one side, thereby further increasing the stability of the equipment. The upper part of the guide rod 08 has a limit 09. The front part of the cylinder frame 05 is fixedly connected to the cylinder 10, and the lower part of the cylinder 10 is fixedly connected to the lifting frame 07. The side of the lifting frame 07 has a cantilever 11. The front part of the equipment column 03 and the lower part of the cantilever 11 are both fixedly connected to the first roller frame 12. The rear part of the first roller frame 12 has a lead screw shaft groove 13, which is adapted to the double threaded rod 14. The lead screw shaft groove 13 is connected to the double threaded rod 14, and the double threaded rod 14 rotates inside the lead screw shaft groove 13.

[0021] Example 2:

[0022] The double threaded rod 14 of this utility model is fixedly connected to the hexagonal head 16 on the side. During the use of the PTFE recycled material strip roller pressing and shaping device, the PTFE recycled material strip is roller pressed and shaped by the two sets of pressure rollers 24 at the front of the frame 04. If the pressure roller 24 is damaged, the hexagonal head 16 on the side of the first roller frame 12 is rotated, so that the hexagonal head 16 drives the positioning pin clamp 18 to move, and the pin 19 inside the pin groove 21 is pulled out. This releases the pin 19 from the second positioning plate 23 on the side of the pressure roller 24, so that the pressure roller 24 can be removed from the equipment for quick replacement, thereby increasing the maintenance efficiency of the equipment. The double threaded rod 14 has a screw thread 15 on the side. The first roller frame 12 is fixedly connected to the first positioning plate 17. The first positioning plate 17 is adapted to the positioning pin clamp 18. The first positioning plate 17 is connected to the positioning pin clamp 18, and the positioning pin clamp 18 slides on the side of the first positioning plate 17.

[0023] Example 3:

[0024] The positioning pin clamp 18 of this utility model is threaded to the rear of the screw thread 15. The front of the first roller frame 12 has a positioning frame 20. The front of the positioning pin clamp 18 is fixedly connected to the pin 19. The positioning frame 20 is adapted to the second roller frame 22 and is connected to the second roller frame 22.

[0025] Example 4:

[0026] In this invention, the second roller frame 22 is inserted into the positioning frame 20. The second roller frame 22 has a second positioning plate 23 on its side. Both the side of the positioning frame 20 and the side of the second positioning plate 23 have pin grooves 21. During the use of the PTFE recycled material strip roller pressing and shaping device, the PTFE recycled material strip is roller pressed and shaped by the two sets of pressure rollers 24 at the front of the frame 04. Together with the two sets of positioning pin clamps 18 on the side of the first roller frame 12, the pins 19 are driven to lock the second positioning plate 23 and lock the second roller frame 22 on both sides of the pressure roller 24. This prevents the first roller frame 12 from bending and jamming due to unilateral force, thereby increasing the stability of the equipment. The pin groove 21 is adapted to the pin 19. The pin groove 21 is connected to the pin 19. The pin 19 is inserted into the pin groove 21. The pressure roller 24 is rotatably connected inside the second roller frame 22.
