Description

Technical Field

[0001] This utility model relates to the field of polytetrafluoroethylene film winding technology, specifically to a polytetrafluoroethylene film winding device. Background Technology

[0002] Polytetrafluoroethylene (PTFE) membranes are resistant to acids, alkalis, and various organic solvents, and are almost insoluble in all solvents. At the same time, PTFE is resistant to high temperatures and has an extremely low coefficient of friction. Therefore, in addition to its lubricating properties, it has become an ideal coating for easy-to-clean water pipe inner layers. It is widely used in light industry, military industry, aerospace, and oil fields. During use, PTFE membranes often need to be adhered to the surface of pipes.

[0003] The prior art discloses a polytetrafluoroethylene (PTFE) film winding device with application number CN202122242335.2, including a support device and a winding mechanism disposed on one side of the support device. The winding mechanism includes a lifting device, and a rotating device is provided on one side of the lifting device. The lifting device includes a lifting plate, and a lifting sleeve is fixedly connected to one side of the lifting plate. The rotating device includes a motor, and a transmission mechanism is fixedly connected to one end of the motor. This invention uses a motor to drive the lifting plate and lifting sleeve to perform vertical reciprocating motion in the processed pipe via a rotating disc and a driving rod. Simultaneously, the motor drives the fixed sleeve to rotate through the transmission mechanism, gear set, and gear column. The fixed sleeve then drives the processed pipe to rotate, achieving uniform spiral bonding of the PTFE film installed on the rotating wheel onto the processed item. This saves manpower while providing a more uniform bonding effect without affecting subsequent use.

[0004] However, after the device fixes the pipe, the clamping and obstruction of the fixing sleeve and fixing rod make it difficult for the bottom of the pipe to be wrapped with polytetrafluoroethylene film, which makes it difficult for the pipe to be completely wrapped, resulting in poor wrapping effect. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a polytetrafluoroethylene film winding device to solve the technical problems in the background art mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a polytetrafluoroethylene (PTFE) film winding device, comprising a base, a support frame and a toothed plate on one side of the top of the base, a motor mounted on the top of the support frame, and a mounting frame connected to the output end of the motor, a reciprocating lead screw fixed inside the mounting frame, a threaded sleeve sleeved on the outer surface of the reciprocating lead screw, a mounting seat movably connected to the outer surface of the threaded sleeve via a bearing, a gear above the outer surface of the threaded sleeve, a fixing frame on one side of the mounting seat, and a second bidirectional lead screw mounted inside the fixing frame. The second bidirectional lead screw has two sets of threaded plates on its outer surface, and the inner side of the threaded plates is connected to a chuck via a connecting shaft. A fixed cylinder runs through the top center of the base, and a first bidirectional lead screw is installed inside the fixed cylinder. A threaded seat is sleeved on the outer surface of the first bidirectional lead screw. A movable rod is hinged around the outer surface of the threaded seat, and a support plate is movably connected to one end of the movable rod. A support plate is fixed on the outer surface of the fixed cylinder. A rotating shaft is installed at the bottom of the base, and a driving bevel tooth is fixed at one end of the rotating shaft. A driven bevel tooth is fixed at the bottom end of the first bidirectional lead screw.

[0007] Furthermore, a support pad is provided on one side of the support plate, and the support pad is arc-shaped.

[0008] By adopting the above technical solution, the arc design can better fit the inner wall of the pipe, improving the fixing effect of the pipe.

[0009] Furthermore, the support pads are provided in four groups, which are arranged in a circular array, and the support pads are made of rubber material.

[0010] By adopting the above technical solution, the four sets of support pads increase the contact area with the inner wall of the pipe, and the rubber material has a large friction force, which further improves the firmness of the pipe fixation.

[0011] Furthermore, a rocker arm is fixed to one end of the rotating shaft, and a rubber sleeve is provided on the outer surface of the rocker arm.

[0012] By adopting the above technical solution, it is easier for workers to rotate the shaft using the crank handle, and the rubber sleeve increases the friction of the crank handle, making it less likely to slip when cranking.

[0013] Furthermore, a knob is fixed to the top of the second bidirectional lead screw, and the outer surface of the knob is provided with anti-slip texture.

[0014] By adopting the above technical solution, the knob makes it easier to rotate the second reciprocating lead screw, and the anti-slip texture increases the friction of the knob, making it less likely for the operator to slip when rotating the knob.

[0015] Furthermore, the toothed plate is arc-shaped and meshes with the gear.

[0016] By adopting the above technical solution, the arc design can better match the revolution trajectory of the gear. When the gear revolves to mesh with the gear plate, the gear will drive the threaded sleeve to rotate.

[0017] Furthermore, a control panel is installed on the other side of the top of the base, and the control panel is electrically connected to the motor.

[0018] By adopting the above technical solution, staff can control the motor through the control panel.

[0019] Furthermore, a sliding rod is installed inside the mounting bracket, and the mounting base slides in conjunction with the sliding rod.

[0020] By adopting the above technical solution, the mounting base can only move vertically under the action of the sliding rod, and will not rotate.

[0021] Furthermore, the clamping plate is provided in two sets, and a film winding cylinder is installed on the inner side of the two sets of clamping plates, and the film winding cylinder is detached from the clamping plate.

[0022] By adopting the above technical solution, the opening and closing of two sets of clamps makes it more convenient to disassemble the film roll after the polytetrafluoroethylene film on the roll has been used up.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model, through a first bidirectional lead screw, threaded seat, movable rod, support plate, active bevel gear, driven bevel gear, rotating shaft, and support plate, allows for the fixing of pipes. When fixing a pipe, the worker inserts the pipe onto the support plate, and then rotates the rotating shaft. The rotation of the rotating shaft causes the active bevel gear to rotate, which in turn causes the driven bevel gear to drive the first bidirectional lead screw to rotate. After the first bidirectional lead screw rotates, the two sets of threaded seats can move in opposite directions, thereby causing the movable rod to expand the support plate. This allows the support pad to fit tightly against the inner wall of the pipe, thus achieving the purpose of fixing the pipe. Moreover, since it fixes the inner wall of the pipe, it does not obstruct the outer surface of the pipe, thus allowing for complete wrapping of the pipe.

[0025] 2. This utility model, equipped with a motor, mounting bracket, reciprocating screw, threaded sleeve, toothed plate, mounting base, and gear, allows for easy winding of the PTFE membrane onto the pipe. The operator attaches one end of the PTFE membrane to the outer surface of the pipe, then starts the motor. The motor's rotation causes the mounting bracket to rotate around the pipe, thus winding the PTFE membrane onto the pipe. After one turn, the gear revolves and meshes with the toothed plate, causing the threaded sleeve to rotate. This rotation, combined with the action of the reciprocating screw, causes the mounting base to move vertically a certain distance, which in turn causes the film roll to move vertically a certain distance, resulting in the PTFE membrane being evenly spirally adhered to the pipe. This makes the operation simpler and more convenient.

[0026] 3. This utility model is equipped with a second reciprocating screw, a threaded plate, and a clamping plate. When it is necessary to replace the film roll, the operator rotates the second reciprocating screw clockwise, which causes the threaded plate to move the clamping plate in the opposite direction, thereby making the film roll disassembled and replaced very conveniently.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1: A device for winding polytetrafluoroethylene film, such as Figures 1-4 As shown, the system includes a base 1, a support frame 2 and a toothed plate 3 on one side of the top of the base 1, a motor 4 mounted on the top of the support frame 2, and a mounting frame 5 connected to the output end of the motor 4. A reciprocating lead screw 6 is fixed inside the mounting frame 5, and a threaded sleeve 18 is fitted onto the outer surface of the reciprocating lead screw 6. A mounting seat 20 is movably connected to the outer surface of the threaded sleeve 18 via a bearing. A gear 19 is provided above the outer surface of the threaded sleeve 18. A fixing frame 22 is provided on one side of the mounting seat 20, and a second bidirectional lead screw 23 is installed inside the fixing frame 22. A sliding rod 21 is installed inside the mounting frame 5, and the mounting seat 20 slides with the sliding rod 21. Under the action of the sliding rod 21, the mounting seat 20 can only move vertically and will not rotate. Two sets of threaded plates 24 are provided on the outer surface of the second bidirectional lead screw 23. The inner side of the base 1 is connected to a clamping plate 26 via a connecting shaft 25. There are two sets of clamping plates 26, and film rolls 27 are installed on the inner side of the two sets of clamping plates 26. The film rolls 27 are detached from the clamping plates 26. By opening and closing the two sets of clamping plates 26, it is more convenient to remove the film rolls 27 after the polytetrafluoroethylene film on the film rolls 27 is used up. A fixed cylinder 7 runs through the middle of the top of the base 1. A first bidirectional lead screw 8 is installed inside the fixed cylinder 7. A threaded seat 9 is sleeved on the outer surface of the first bidirectional lead screw 8. A movable rod 10 is hinged around the outer surface of the threaded seat 9. A support plate 11 is movably connected to one end of the movable rod 10. A support plate 13 is fixed on the outer surface of the fixed cylinder 7. A rotating shaft 15 is installed at the bottom of the base 1. An active bevel tooth 16 is fixed at one end of the rotating shaft. A driven bevel tooth 14 is fixed at the bottom end of the first bidirectional lead screw 8.

[0035] See Figures 1-3 In the above embodiment, a handle 17 is fixed to one end of the rotating shaft 15, and a rubber sleeve is provided on the outer surface of the handle 17. The operator can make it easier to rotate the rotating shaft 15 by using the handle 17. The rubber sleeve increases the friction of the handle 17, making it less likely to slip when the handle 17 is shaken.

[0036] See Figure 2 and Figure 4 In the above embodiment, a knob 29 is fixed to the top of the second bidirectional lead screw 23, and the outer surface of the knob 29 is provided with anti-slip texture. The knob 29 makes it easier for the second reciprocating lead screw 6 to rotate, and the anti-slip texture increases the friction of the knob 29, making it less likely for the operator to slip when rotating the knob 29.

[0037] See Figures 1-2In the above embodiment, the toothed plate 3 is arc-shaped and meshes with the gear 19. The arc-shaped design can better match the revolution trajectory of the gear 19. When the gear 19 revolves to mesh with the toothed plate 3, the gear 19 will drive the threaded sleeve 18 to rotate.

[0038] See Figures 1-2 In the above embodiment, a control panel 28 is installed on the other side of the top of the base 1, and the control panel 28 is electrically connected to the motor 4. The operator can control the motor 4 through the control panel 28.

[0039] Example 2: To make the pipeline more stable, Example 2 is an improvement on Example 1. (See attached document.) Figures 2-3 The support plate 11 has a support pad 12 on one side. The support pad 12 is arc-shaped. The arc design can better fit the inner wall of the pipe and improve the fixing effect of the pipe. There are four sets of support pads 12, which are distributed in a ring array. The support pads 12 are made of rubber material. The four sets of support pads 12 increase the contact area with the inner wall of the pipe. The rubber material has a large friction force, which further improves the firmness of fixing the pipe.

[0040] The implementation principle of this utility model is as follows: The operator places the pipe on the support plate 13, and then rotates the rotating shaft 15. The rotation of the rotating shaft 15 causes the active bevel gear 16 to rotate, which in turn causes the driven bevel gear 14 to drive the first bidirectional lead screw 8 to rotate. After the first bidirectional lead screw 8 rotates, it enables the two sets of threaded seats 9 to move in opposite directions, thereby causing the movable rod 10 to expand the support plate 11, so that the support pad 12 is tightly attached to the inner wall of the pipe, thereby achieving the purpose of fixing the pipe. The operator then attaches one end of the polytetrafluoroethylene film to the outer surface of the pipe, and then starts the motor 4. The rotation of the motor 4 causes the mounting bracket 5 to rotate around the pipe. The pipe rotates, causing the PTFE membrane to wrap around it. After one turn, when gear 19 revolves and meshes with toothed plate 3, gear 19 drives threaded sleeve 18 to rotate. The rotation of threaded sleeve 18, combined with the action of reciprocating screw 6, causes mounting base 20 to move vertically a certain distance, which in turn causes film roll 27 to move vertically a certain distance, so that the PTFE membrane is evenly spirally attached to the pipe. When film roll 27 needs to be replaced, the operator rotates the second reciprocating screw 6 clockwise, which causes threaded plate 24 to drive clamp 26 to move in the opposite direction, thereby allowing film roll 27 to be disassembled.
