Description

Technical Field

[0001] This utility model belongs to the field of PTFE membrane production technology, specifically an antistatic winding device for PTFE membrane production. Background Technology

[0002] PTFE membranes are widely used in chemical, environmental protection, and medical fields due to their outstanding chemical stability, high and low temperature resistance, and weather resistance. In the production process of PTFE membranes, winding is an indispensable key step. However, due to the inherent characteristics of PTFE membrane materials, static electricity is easily generated during the winding stage. The presence of static electricity can not only cause the membrane material to attract dust and other impurities, thus affecting product quality, but may also cause the membrane materials to stick together, resulting in uneven winding and even safety hazards.

[0003] In the prior art, some PTFE membrane winding devices are equipped with static eliminators, such as ion air bars or ion air guns, which eliminate static electricity on the PTFE membrane by spraying ion air onto the PTFE membrane surface.

[0004] However, it should be noted that some antistatic winding devices, in order to ensure that static electricity can be eliminated on both sides of the PTFE membrane at the same time, will install a set of ion air bars on the top and bottom sides of the PTFE membrane. Although setting two sets of ion air bars can ensure the effect of comprehensive static electricity elimination, this will significantly increase the installation cost and subsequent maintenance cost, resulting in a significant reduction in practicality. Therefore, in order to address the above problems, an antistatic winding device for PTFE membrane production is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] Please see Figures 1-6 This utility model provides an antistatic winding device for PTFE membrane production, including a support frame 1; a winding mechanism 2 is provided on the top of the support frame 1, a support plate 31 is fixedly connected to the side of the support frame 1, an ion gun 3 is fixedly connected to the top of the support plate 31, a quick connector 37 is installed at the end of the ion gun 3, a cylindrical tube 32 is fixedly connected to the end of the quick connector 37, an air inlet pipe 36 is slidably connected to the middle of the cylindrical tube 32, and a U-shaped tube 33 is fixedly connected to the end of the air inlet pipe 36. A connecting pipe 34 is slidably connected to the middle section, and a second U-shaped pipe 35 is slidably connected to the outer wall of the other end of the connecting pipe 34. An adjustment component is provided in the middle of the support frame 1. The adjustment component includes a rectangular block 44. The top of the rectangular block 44 contacts the bottom of the second U-shaped pipe 35. An insert block 51 is fixed to the bottom of the second U-shaped pipe 35 and is inserted into the middle of the rectangular block 44. A through groove 6 is provided on the side wall of the support frame 1. The outer walls of the first U-shaped pipe 33, the connecting pipe 34, and the second U-shaped pipe 35 are all provided with... The vent is located at the exhaust port. During operation, the PTFE membrane is wound up using the winding mechanism 2. When fixing one end of the PTFE membrane to the winding mechanism 2, it needs to pass through the middle of the U-shaped tube 33. During winding, the ion gun 3 can be activated to spray ion air. The ion air will enter the middle of the U-shaped tube 33 through the cylindrical tube 32 and the air inlet tube 36, then enter the middle of the connecting tube 34 and the second U-shaped tube 35, and finally be discharged through the exhaust port. The air is sprayed onto the surface of the PTFE membrane to eliminate static electricity. This eliminates the need to install multiple sets of ion air bars to remove static electricity from the surface of the PTFE membrane, reducing installation costs and subsequent maintenance costs. The connection distance between the U-shaped tube 33, the connecting tube 34, and the second U-shaped tube 35 can be adjusted according to the width of the PTFE membrane to ensure the effect of removing static electricity. When adjusting, the position of the U-shaped tube 33 and the second U-shaped tube 35 can be adjusted simply by using the set adjustment components, improving practicality.

[0020] Furthermore, such as Figure 2 and Figures 4-5As shown, a support slide rail 5 is fixedly connected to the top of the support frame 1. A slider 57 is slidably connected to the middle of the support slide rail 5. The side wall of the slider 57 is fixedly connected to the side wall of the top of the rectangular block 44. A limit block 56 is slidably connected through the side wall of the top of the rectangular block 44. The outer wall of the limit block 56 is slidably connected to the middle of the slider 57. A rectangular groove 52 is opened on the side wall of the insert block 51. The limit block 56 is inserted into the middle of the rectangular groove 52. A round rod 54 is slidably connected through the side wall of the slider 57. A telescopic rod 53 is fixedly connected to the side wall of the end of the round rod 54. The other end of the round rod 54 is fixedly connected to the side wall of the limit block 56. During operation, when the U-shaped tube 1 33, the connecting tube 34, and the U-shaped tube 2 35 need to be disassembled and replaced after a period of use, the cylindrical tube 32 is first separated from the ion gun 3 using the quick connector 37. Then the telescopic rod 53 can be pulled. The telescopic rod 53 will drive the round rod 54 and the limiting block 56 to move synchronously until the limiting block 56 disengages from the middle of the inner wall of the rectangular groove 52, at which point the connecting tube 34 can be pulled. At this time, the U-shaped tube 33, the connecting tube 34 and the U-shaped tube 35 will move synchronously, and the insert 51 will also disengage from the middle of the rectangular block 44, thus completing the disassembly. During installation, simply insert the insert 51 into the middle of the rectangular block 44. During the insertion process, the insert 51 will push the limiting block 56 along the inclined surface to move. The limiting block 56 will drive the round rod 54 to move, and the round rod 54 will stretch the spring 55 until the limiting block 56 coincides with the rectangular groove 52. At this time, the spring 55 will pull the round rod 54 and the limiting block 56 to reset through its own elasticity, so that the limiting block 56 is inserted into the middle of the rectangular groove 52. Then, the ion gun 3 and the cylindrical tube 32 can be connected together through the quick connector 37.

[0021] Furthermore, such as Figures 1-4 As shown, the adjustment assembly also includes an L-shaped sliding plate 41. The outer wall of one end of the L-shaped sliding plate 41 is slidably connected to the middle of the through groove 6. A hinge block 42 is fixedly connected to the top of the other end of the L-shaped sliding plate 41. A connecting plate 43 is rotatably connected to the middle of the hinge block 42. The other end of the connecting plate 43 is rotatably connected to the inner wall of the bottom of the rectangular block 44. During operation, when adjusting the connection distance between the first U-shaped tube 33, the connecting tube 34, and the second U-shaped tube 35, the L-shaped sliding plate 41 can be pushed. The L-shaped sliding plate 41 drives the hinge block 42 to move, and the angle of the connecting plate 43 will change accordingly. As the air intake pipe moves, one end of the U-shaped tube rotates with the hinge block 42, and the other end rotates with the rectangular block 44, causing the rectangular block 44 to move. The rectangular block 44 then moves the insert block 51 and the second U-shaped tube 35. Simultaneously, the rectangular block 44 causes the slider 57 to slide in the middle of the support rail 5. The movement of the first U-shaped tube 33 and the second U-shaped tube 35 is the same. The first U-shaped tube 33 also moves the intake pipe 36 to adjust its position. This brings the distance between the first U-shaped tube 33 and the second U-shaped tube 35 closer, and the width of the spray also changes.

[0022] Furthermore, such as Figure 6 As shown, the support frame 1 has a groove 7 on one side of the through groove 6. A connecting block 4 is fixed to the end of the L-shaped slide plate 41. A rod 45 is slidably connected through the side wall of the connecting block 4. The rod 45 is inserted into the middle of the groove 7. A spring 46 is sleeved on the outer wall of the rod 45. One end of the spring 46 is fixed to the side wall of the connecting block 4, and the other end is fixed to the outer wall of the rod 45. During operation, the stability of the L-shaped slide plate 41 can be ensured by the cooperation between the rod 45 and the spring 46. The connection distance between the U-shaped tube 33, the connecting tube 34 and the U-shaped tube 35 can also be stabilized. During adjustment, the rod 45 can be pulled to disengage it from the middle of the groove 7. The rod 45 will stretch the spring 46. After adjustment, the rod 45 can be released. At this time, the spring 46 will pull the rod 45 back to its original position through its elasticity, so that it can be inserted into the middle of another set of grooves 7, which improves practicality.

[0023] Furthermore, such as Figure 5 As shown, a second spring 55 is sleeved on the outer wall of the round rod 54. One end of the second spring 55 is fixed to the side wall of the slider 57, and the other end of the second spring 55 is fixed to the side wall of the round rod 54. During operation, the second spring 55 ensures that when the telescopic rod 53 is not pulled, and the insert block 51 is inserted into the middle of the rectangular block 44, the limiting block 56 is always inserted into the middle of the rectangular groove 52 to limit its movement, thus ensuring the stability of the installation of the first U-shaped tube 33, the connecting tube 34, and the second U-shaped tube 35.

[0024] Furthermore, such as Figure 5 As shown, the side wall of the limiting block 56 is set as an inclined surface. When working, the insertion block 51 is inserted into the middle of the rectangular block 44 through the inclined surface, without the need for manual operation of the telescopic rod 53, which improves convenience.

[0025] Furthermore, such as Figure 2 and Figure 5 As shown, multiple sets of connecting plates 43, rectangular blocks 44, and insert blocks 51 are provided, and these multiple sets of connecting plates 43, rectangular blocks 44, and insert blocks 51 are symmetrically arranged with the center line of the hinge block 42 as the axis of symmetry. The multiple sets of insert blocks 51 are specifically fixed to the bottom of the U-shaped tube 33. During operation, the U-shaped tube 33 can run stably through the multiple sets of connecting plates 43, rectangular blocks 44, and insert blocks 51, which improves its practicality.

[0026] Working principle: The PTFE membrane is wound up using the winding mechanism 2. When fixing one end of the PTFE membrane to the winding mechanism 2, it needs to pass through the middle of the U-shaped tube 33. During winding, the ion gun 3 can be activated to spray ion air. The ion air will enter the middle of the U-shaped tube 33 through the column tube 32 and the air inlet tube 36, and then enter the middle of the connecting tube 34 and the second U-shaped tube 35. Finally, it will be discharged through the exhaust hole and sprayed onto the surface of the PTFE membrane to eliminate static electricity. This eliminates the need to install multiple sets of ion air bars to remove static electricity from the surface of the PTFE membrane, reducing installation costs and subsequent maintenance costs.

[0027] The connection distance between U-shaped tube 33, connecting tube 34, and U-shaped tube 35 can be adjusted according to the width of the PTFE membrane to ensure the antistatic effect. During adjustment, the L-shaped slide plate 41 can be pushed, which drives the hinge block 42 to move. At this time, the angle of the connecting plate 43 will change accordingly. At the same time, one end of the plate will rotate with the hinge block 42, and the other end will rotate with the rectangular block 44, thus driving the rectangular block 44 to move. The rectangular block 44 will drive the insert block 51 and U-shaped tube 35 to move. At the same time, the rectangular block 44 will drive the slider 57 to slide in the middle of the support rail 5. The movement of U-shaped tube 33 and U-shaped tube 35 is the same. U-shaped tube 33 will also drive the air intake pipe 36 to move, thus adjusting its position. In this way, the distance between U-shaped tube 33 and U-shaped tube 35 will become closer, and the spray width will also change.

[0028] When U-shaped tube 33, connecting tube 34, and U-shaped tube 35 need to be disassembled and replaced after a period of use, first use quick connector 37 to separate cylindrical tube 32 from ion gun 3. Then, pull telescopic rod 53. Telescopic rod 53 will drive round rod 54 and limiting block 56 to move synchronously until limiting block 56 disengages from the middle of the inner wall of rectangular groove 52. Then, pull connecting tube 34. At this time, U-shaped tube 33, connecting tube 34, and U-shaped tube 35 will move synchronously, and insert block 51 will also disengage from the middle of rectangular block 44. Disassembly is then complete. During installation, simply insert the insert 51 into the middle of the rectangular block 44. During insertion, the insert 51 will move along the inclined surface of the limiting block 56. The limiting block 56 will drive the round rod 54 to move, and the round rod 54 will stretch the second spring 55 until the limiting block 56 coincides with the rectangular groove 52. At this time, the second spring 55 will pull the round rod 54 and the limiting block 56 to reset through its own elasticity, so that the limiting block 56 is inserted into the middle of the rectangular groove 52. Then, the ion gun 3 and the cylindrical tube 32 can be connected together through the quick connector 37.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
