Description

Technical Field

[0001] The invention relates to the technical field of winding devices, in particular to a film winding device for PTFE long fibers. Background Art

[0002] PTFE fiber is mainly prepared by film splitting fiber technology, and the process includes mixing, standing, preforming, push forming, calendering, degreasing, hot stretching, film splitting fiber, curling, cutting, opening, and finished products. First, mix PTFE dispersed powder and lubricant to prepare a paste, and then stand the paste in an appropriate temperature environment for a period of time. After standing, the paste is preformed and pushed to form a continuous thin rod; the calendering process uses a pair of calendering rollers to extrude the continuous thin rod obtained from the previous process to prepare a calendered film and wind it, and then move the roll of calendered film to the winding device to provide the tension required for degreasing and hot stretching processing and obtain a stretched film, and finally use a film splitting needle roller to puncture and comb the stretched film to obtain PTFE film split fiber.

[0003] The current winding device has certain shortcomings:

[0004] The traditional winding device only relies on friction to fix the PTFE long fiber membrane roll, which is prone to slippage during rotation and has little control over the PTFE long fiber membrane roll. This can easily cause wrinkles in the PTFE long fiber membrane during the winding process, affecting subsequent use. In addition, the device can only fix PTFE long fiber membrane rolls with a single pore size, which is not convenient to use.

[0005] The PTFE long fiber membrane is prone to varying degrees of positional deviation during the winding process, which requires the edges of the waterproof membrane to be trimmed later, resulting in waste of scraps. In addition, the deviation of the PTFE long fiber membrane seriously affects the appearance of the finished waterproof membrane.

[0006] At the same time, when the PTFE long fiber membrane is being rolled up, the transported membrane is not tight enough during transmission, which not only causes the membrane to contact the ground, but also causes the membrane to not be tightly wrapped around the winding drum during rolling, causing the volume of the PTFE long fiber membrane roll to increase and easily causing the dense roll to spread out. Summary of the invention

[0018] Compared with the prior art, the present invention provides a film winding device for PTFE long fibers, which has the following beneficial effects:

[0019] 1. The present invention can change the transmission of the connecting shaft and the rotating sleeve by sliding the transmission sleeve on the outside of the rotating sleeve, so that the rotating sleeve and the connecting shaft can rotate and transmit when needed. The sliding of the transmission sleeve can quickly switch the transmission object. When the four sets of arc plates are needed to be unfolded and expanded, the transmission sleeve can be slid on the outside of the rotating sleeve, so that the connecting groove and the connecting block are separated from each other, driving the first annular rack and the third transmission gear to engage with each other, and the transmission sleeve drives the third transmission gear to rotate through the cooperation of the second annular rack and the second transmission gear, so that the connecting shaft rotates, and the four sets of telescopic plates are pushed to the outside of the rotating cylinder through the action of the driving rod and the driving groove. The four sets of arc plates are unfolded, so that film rolls of different diameters can be supported and fixed, wrinkles are prevented during winding, and the quality of winding is improved.

[0020] 2. The present invention utilizes an anti-deviation component arranged above the rotating drum. When the film is rolled up, two sets of limit bars can be placed on both sides of the film roll. The two sets of limit bars can be driven to move closer to and away from each other by rotating the bidirectional threaded rod. The distance between the two sets of limit bars can be adjusted according to the width of the film roll. When the film is rolled up and unrolled, the film can be effectively prevented from deviating on the outside of the film roll, thereby ensuring the quality of the film when unrolling and rolling up. The invention has a wide range of applications.

[0021] 3. The present invention can make the film more stable and smooth when moving by rotating two sets of guide rollers. By changing the position between the two sets of guide rollers, the film transmission path can be changed, and the distance the film moves becomes longer. The tightness of the film during transmission can be effectively adjusted to prevent the film from becoming loose during transmission, resulting in insufficient fit between the film and the film roll when winding, further preventing wrinkles in the film and preventing the film roll from becoming loose.

[0040] Embodiment 1, as Figure 4-6 As shown, after the four groups of arc plates 8 are adjusted, the servo motor 6 is stopped, and the mobile transmission sleeve 404 slides on the outside of the rotating sleeve 13, so that the transmission sleeve 404 drives the connecting groove 403 to move toward the connecting block 19, so that the connecting block 19 moves to the inside of the connecting groove 403, and the first annular rack 402 disengages from the third transmission gear 14 at the same time and no longer meshes with the third transmission gear 14, while the second transmission gear 405 and the second annular rack 406 slide but are always in a meshing state, and then the servo motor 6 is turned on, and the transmission sleeve 401 is driven to rotate through the belt shaft 7 and the transmission belt 5, so that the transmission sleeve 401 drives the transmission sleeve 404 to rotate through the cooperation of the second transmission gear 405 and the second annular rack 406, and the transmission sleeve 404 drives the rotating sleeve 13 to rotate through the cooperation of the connecting groove 403 and the connecting block 19, and the rotating sleeve 13 drives the rotating cylinder 12 to rotate, and the film roll on the outside of the arc plate 8 is wound.

[0041] Embodiment 2, as Figure 1 and 3As shown, when the film is transmitted, the fastening bolt 206 is rotated inside the first rotating shaft 205 to release the fixation of the first rotating shaft 205. At this time, the first rotating shaft 205 slides inside the arc guide rail 207 and the arc groove 202 at the same time, so that the position of a group of first rotating shafts 205 can be changed, so that a group of first rotating shafts 205 continuously moves upward along the arc guide rail 207, which can make the film S-shaped, increase the transmission distance of the film, and can effectively tighten the film so that it can better fit with the film roll when winding.

[0042] Working principle: First, when the PTFE long fiber membrane is rolled up, the membrane roll is put on the outside of the four groups of arc plates 8, and the transmission sleeve 404 is moved along the outside of the rotating sleeve 13 to the third transmission gear 14, so that the connecting groove 403 and the connecting block 19 are separated from each other, so that the first annular rack 402 and the third transmission gear 14 are meshed with each other, and the servo motor 6 is turned on to drive the belt shaft 7 and the second rotating shaft 208 to rotate, and the belt shaft 7 drives the transmission sleeve 401 to rotate through the transmission belt 5, and the transmission sleeve 401 drives the transmission sleeve 404 to rotate through the cooperation of the second transmission gear 405 and the second annular rack 406. The transmission sleeve 404 drives the third transmission gear 14 to rotate through the first annular rack 402, and the connecting shaft 9 rotates with the third transmission gear 14, driving the two sets of turntables 15 to rotate, and the telescopic plate 17 and the arc plate 8 are driven to move through the driving rod 16 and the driving groove 18, so that the full arc plate 8 supports and fixes the inner side of the film roll. When winding, the two-way threaded rod 303 is rotated to drive the two sets of limit stop rods 304 to slide inside the limit slide groove 305, changing the distance between the two sets of limit stop rods 304, and adjusting the two sets of limit stop rods 304 to the most suitable position according to the size of the film width to prevent the film from deflecting during winding;

[0043] By rotating the two sets of guide rollers 203, the film can be made more stable when moving. By changing the position of one set of guide rollers 203, the moving path of the film can be changed to lengthen the transmission distance. The tightness of the film can be changed to make it tighter when winding, preventing the film roll from unraveling.

[0044] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
