Description

Technical Field

[0001] The utility model relates to the technical field of winding devices, and more specifically to a PTFE film winding device. Background Technique

[0002] The PTFE film is made of polytetrafluoroethylene as raw material by special processes such as calendering, extrusion, and biaxial stretching. During production, it is usually wound around the surface of a winding roller for convenient transportation.

[0003] After retrieval, the existing patent (publication number: CN217971810U) discloses a winding device for PTFE waterproof and moisture-permeable films. During its use, the motor drives the winding roller to rotate to realize the winding action of the PTFE film. And during the winding process, by setting a pressing roller, the pressing roller presses the pressing plate towards the winding roller through a torsion spring to achieve a tighter effect when winding the film. However, the inventor found the following problems in the process of implementing the present utility model: For the above-mentioned winding device, by setting an L-shaped limiting plate, the U-shaped through groove opened on the L-shaped limiting plate cooperates with the accommodating groove to achieve the effect of limiting the winding roller. After the film winding is completed, the L-shaped limiting plate needs to be moved before the winding roller can be unloaded. And after unloading, the L-shaped limiting plate needs to be operated repeatedly to complete the installation of the winding roller for continuing the film winding work. It has the defects of cumbersome and time-consuming disassembly, and during the process of disassembling and installing the winding roller, the whole device is in a shutdown state, which reduces the winding efficiency of the film and is difficult to meet the requirements of high-efficiency production.

[0004] In view of this, the present utility model proposes a PTFE film winding device to solve this problem. Content of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the present utility model provides a PTFE film winding device to solve the problems existing in the above background technique.

[0006] The present utility model provides the following technical solution: A PTFE film winding device includes a base, a mounting frame is fixedly installed on the surface of the base, a switching shaft is rotatably connected to the mounting frame, two winding components are symmetrically arranged on the surface of the switching shaft, a switching component is arranged between the mounting frame and the switching shaft, and a pressing component is arranged on the surface of the mounting frame corresponding to the upper winding component;

[0007] The swapping component includes a swapping box fixedly installed on the right side of the mounting frame. The swapping shaft is rotatably connected to the swapping box. A worm gear is fixedly installed inside the swapping box on the swapping shaft. A stepping motor is fixedly installed on the back of the swapping box. The output shaft of the stepping motor extends into the swapping box and is fixedly installed with a worm, and the worm meshes with the worm gear;

[0008] The pressing component includes a vertical sliding rod inserted on the surface of the mounting frame. A lower pressing plate is fixedly installed at the bottom end of the vertical sliding rod.

The bottom end of the return spring abuts against the top end of the lower pressing plate, and the top end of the return spring abuts against the inner top wall of the mounting frame.

[0009] Furthermore, the winding component includes two side plates symmetrically and fixedly installed on the surface of the swapping shaft. A left - right hand thread screw is rotatably connected between the two side plates. A servo motor for driving the left - right hand thread screw to rotate is fixedly installed on the surface of the right - hand side plate. Two clamping plates are symmetrically threadedly connected to the surface of the left - right hand thread screw. A top column is rotatably connected to the side of the two clamping plates close to each other, and the top column is adapted to the central hole of the external winding drum. A winding motor for driving the right - hand side top column to rotate is fixedly installed on the surface of the right - hand side clamping plate.

[0010] Furthermore, a pin block is fixedly installed on the surface of the top column, and the pin block is clamped with the anti - rotation groove at the end of the external winding drum; by providing a pin block on the surface of the top column and using the pin block to be clamped with the winding drum, it can prevent the winding drum from rotating on its own on the surface of the top column, ensuring that the winding motor can normally drive the winding drum to rotate and wind the film.

[0011] Furthermore, a horizontal sliding rod is fixedly installed between the two side plates, and the clamping plate is slidably connected to the horizontal sliding rod; by providing a horizontal sliding rod, the moving path of the clamping plate can be limited, avoiding the deflection of the clamping plate on the surface of the left - right hand thread screw.

[0012] Furthermore, a conductive slip ring is fixedly installed on the left side of the mounting frame, and the rotating end of the conductive slip ring is fixed to the left end of the swapping shaft; by providing a conductive slip ring, during the rotation of the swapping shaft, the purpose of continuously supplying power to the electrical appliance can be achieved.

[0013] Furthermore, a blanking ramp is provided on the surface of the base; by providing a blanking ramp, it is convenient to stably slide the fully - loaded winding drum to the external ground.

[0014] Furthermore, the number of the vertical sliding rods is two, and a scale line is provided on the surface of the right - hand side vertical sliding rod; by providing a scale line, as the winding work progresses, the diameter of the film roll gradually increases and presses the lower pressing plate upward, driving the vertical sliding rod to move upward.

[0015] Furthermore, a connecting plate is fixedly installed at the top end of the vertical sliding rod, and a hydraulic rod is fixedly installed at the top end of the mounting frame.

[0016] The technical effects and advantages of the present utility model:

[0017] 1. In the present utility model, by setting two winding assemblies, when using the upper winding assembly for winding, the lower pressing plate is pressed downward by the return spring, and the film is rolled by the rollers, which can improve the tightness of the film winding. After the upper winding assembly finishes winding, by setting the replacement assembly, the stepping motor drives the worm to rotate. Based on the meshing of the worm and the worm gear, the replacement shaft is driven to rotate, so that the upper and lower take-up reels are swapped. Then, the upper winding assembly is continued to be used for winding work, and the take-up reel is loaded and unloaded at the position of the lower winding assembly, thereby shortening the downtime of the device and achieving the purpose of improving the film winding efficiency.

[0018] 2. In the present utility model, by setting a pin block on the surface of the top column and engaging the pin block with the take-up reel, the take-up reel can be prevented from rotating on its own on the surface of the top column, ensuring that the winding motor can drive the take-up reel to rotate for winding the film. By setting the horizontal sliding rod, the moving path of the clamping plate can be limited to prevent the clamping plate from deflecting on the surface of the left - right threaded screw. By setting the conductive slip ring, during the rotation of the replacement shaft, the purpose of continuously supplying power to the electrical appliance can be achieved. By setting the unloading ramp, it is convenient to stably slide the fully loaded take-up reel to the external ground. By setting the scale line, on the premise that the outer diameter of the take-up reel is known, referring to the scale line, the winding thickness of the film can be measured. By setting the hydraulic rod, when the hydraulic rod extends to push the connecting plate upward, the extrusion effect of the lower pressing plate on the top take-up reel can be cancelled, facilitating the replacement of the take-up reel when the replacement shaft rotates.

Detailed implementation mode

[0024] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure described in the following implementation modes are merely examples. A PTFE film winding device related to the present invention is not limited to the structures described in the following implementation modes. All other implementation modes obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] Referring to Figures 1-4 , the present invention provides a PTFE film winding device, including a base 1, a mounting frame 2 fixedly installed on the surface of the base 1, a replacement shaft 3 rotatably connected to the mounting frame 2, and two winding assemblies symmetrically arranged on the surface of the replacement shaft 3.

[0026] The winding assembly includes two side plates 12 symmetrically and fixedly installed on the surface of the replacement shaft 3. A right and left hand screw 13 is rotatably connected between the two side plates 12. A servo motor 14 for driving the rotation of the right and left hand screw 13 is fixedly installed on the surface of the right side plate 12. Two clamping plates 15 are symmetrically threadedly connected to the surface of the right and left hand screw 13. Ejector pins 16 are rotatably connected to the adjacent sides of the two clamping plates 15. The ejector pins 16 are adapted to the central holes of the external winding drums. A winding motor 17 for driving the rotation of the right side ejector pin 16 is fixedly installed on the surface of the right clamping plate 15.

[0027] When using this winding device, first connect the overall device to an external power control system, and then place a suitable winding drum between the two clamping plates 15. By driving the rotation of the right and left hand screw 13 by the servo motor 14, the two clamping plates 15 can be driven to approach each other. The ejector pins 16 are inserted into the central holes at the ends of the winding drum to install and position the winding drum. Subsequently, the winding motor 17 is used to drive the rotation of the ejector pins 16, thereby driving the rotation of the winding drum to perform the PTFE film winding operation.

[0028] A pin block 18 is fixedly installed on the surface of the ejector pin 16, and the pin block 18 is clamped with the anti-rotation groove at the end of the external winding drum.

[0029] By arranging a pin block 18 on the surface of the top post 16 and engaging the pin block 18 with the winding drum, the rotation of the winding drum on the surface of the top post 16 can be prevented, ensuring that the winding motor 17 can normally drive the winding drum to rotate and wind the film.

[0030] A transverse slide bar 20 is fixedly installed between the two side plates 12, and the clamping plate 15 is slidably connected to the transverse slide bar 20.

[0031] By arranging the transverse slide bar 20, the moving path of the clamping plate 15 can be limited, preventing the clamping plate 15 from deflecting on the surface of the right and left hand screw 13.

[0032] An adjustment assembly is arranged between the mounting frame 2 and the adjustment shaft 3.

[0033] A conductive slip ring 19 is fixedly installed on the left side of the mounting frame 2, and the rotating end of the conductive slip ring 19 is fixed to the left end of the adjustment shaft 3.

[0034] By arranging the conductive slip ring 19, during the rotation of the adjustment shaft 3, the purpose of continuously powering the electrical appliance can be achieved.

[0035] The adjustment assembly includes an adjustment box 4 fixedly installed on the right side of the mounting frame 2. The adjustment shaft 3 is rotatably connected to the adjustment box 4. A worm gear 5 is fixedly installed inside the adjustment box 4 on the adjustment shaft 3. A stepping motor 6 is fixedly installed on the back of the adjustment box 4. The output shaft of the stepping motor 6 extends into the adjustment box 4 and is fixedly installed with a worm 7, and the worm 7 meshes with the worm gear 5.

[0036] After the upper winding assembly finishes winding, by arranging the adjustment assembly, the stepping motor 6 is used to drive the worm 7 to rotate. Based on the meshing of the worm 7 and the worm gear 5, the adjustment shaft 3 is driven to rotate, so that the upper and lower winding drums are swapped. Then, the upper winding assembly is continued to be used for winding work, and the winding drum is loaded and unloaded at the position of the lower winding assembly, thereby shortening the downtime of the device for loading the winding drum, and thus achieving the purpose of improving the film winding efficiency.

[0037] A pressing assembly is arranged on the surface of the mounting frame 2 corresponding to the upper winding assembly.

[0038] The pressing assembly includes a vertical slide bar 8 inserted on the surface of the mounting frame 2. The bottom end of the vertical slide bar 8 is fixedly installed with a lower pressing plate 9. A roller 10 is rotatably connected to the surface of the lower pressing plate 9. A return spring 11 is sleeved on the surface of the vertical slide bar 8. The bottom end of the return spring 11 abuts against the top end of the lower pressing plate 9, and the top end of the return spring 11 abuts against the inner top wall of the mounting frame 2.

[0039] It should be noted that when winding the film, by the return spring 11 pressing the lower pressing plate 9 downward and using the roller 10 to roll the film, the winding tightness of the film can be improved, and thus the winding quality of the film can be improved.

[0040] There are two vertical sliding rods 8, and scale lines 22 are provided on the surface of the right vertical sliding rod 8.

[0041] By setting the scale lines 22, as the winding work progresses, the diameter of the film roll gradually increases and upwardly presses the lower pressing plate 9, driving the vertical sliding rod 8 to move upward. On the premise that the outer diameter of the winding drum is known, referring to the scale lines 22, the winding thickness of the film can be measured.

[0042] A connecting plate 23 is fixedly installed at the top end of the vertical sliding rod 8, a hydraulic rod 24 is fixedly installed at the top end of the mounting frame 2, and the telescopic end of the hydraulic rod 24 abuts against the bottom end of the connecting plate 23.

[0043] It should be noted that by setting the hydraulic rod 24, the hydraulic rod 24 extends to upwardly push the connecting plate 23, which can cancel the extrusion effect of the lower pressing plate 9 on the top winding drum, facilitating the replacement of the winding drum when the rotating shaft 3 rotates.

[0044] A blanking ramp 21 is provided on the surface of the base 1.

[0045] By setting the blanking ramp 21, it is convenient to stably slide the fully loaded winding drum to the external ground.

[0046] Finally, it should be noted that in the attached drawings of the disclosed embodiments of the present utility model, only the structures related to the disclosed embodiments are involved. For other structures, reference can be made to the general design. Without conflict, the same embodiment and different embodiments of the present utility model can be combined with each other.
