AI Technical Summary
Existing waterproof membranes are prone to longitudinal wrinkles during the winding process, and existing solutions either reduce production efficiency or increase costs, failing to effectively solve this problem.
Introducing pressure rollers into the winding system allows for the synchronous application of pressure to the roll material via upper and lower pressure rollers, fixing the roll material to the roll shaft as a whole, isolating the transmission of roll material vibration, and preventing wrinkles from forming.
It effectively reduces the wrinkling of roll materials, maintains the flat appearance of roll materials, improves production efficiency and reduces costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproof technology, and in particular to a winding system with anti-wrinkle function. Background Technology
[0002] Currently, the surface wrinkling of domestically produced asphalt waterproof membranes, especially non-woven membranes, is severe and widespread, representing a major pain point in the industry. During production, the membrane appears relatively smooth on the forming line, but after winding, numerous wrinkles appear, particularly longitudinal wrinkles, resulting in an unsightly appearance. To address this, companies employ two methods: ① reducing production speed and winding speed to minimize wrinkle formation during winding; ② using thicker, harder surface or core films to resist wrinkle formation. However, these methods fail to fundamentally solve the wrinkling problem caused by winding and also reduce production efficiency and increase product costs. Utility Model Content
[0003] This invention provides a winding system with anti-wrinkle function, which can effectively reduce wrinkles generated during the production of waterproof membranes.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a winding system with anti-wrinkle function, comprising a frame and a roll mounted on the frame; further comprising a pair of telescopic mechanisms mounted on the frame, the telescopic mechanisms comprising an upper telescopic unit and a lower telescopic unit, the upper telescopic unit being located above the roll and the lower telescopic unit being located below the roll; further comprising a pair of pressure roller groups, the pressure roller groups comprising an upper pressure roller and a lower pressure roller, the upper pressure roller being connected to the upper telescopic unit and the lower pressure roller being connected to the lower telescopic unit; the upper pressure roller being capable of vertical displacement under the drive of the upper telescopic unit, and the lower pressure roller being capable of vertical displacement under the drive of the lower telescopic unit; the roll is arranged parallel to both the upper and lower pressure rollers.
[0005] Preferably, the upper telescopic unit is any one of a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.
[0006] Preferably, the lower telescopic unit is any one of a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.
[0007] This invention employs pressure rollers to apply pressure to the rolled waterproof membrane during winding. The presence of the pressure rollers can fix the membrane and the roll as one unit, reducing irregular vibration of the roll. At the same time, it can also isolate the shaking between the rolled and unrolled membrane, eliminating wrinkles caused by shaking and keeping the membrane flat. Attached Figure Description

[0009] Among them, 1-frame; 11-upper support; 12-lower support; 2-roller; 31-first cylinder; 32-second cylinder; 33-third cylinder; 34-fourth cylinder; 4-upper pressure roller; 5-lower pressure roller. Detailed Implementation
[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0011] like Figure 1 As shown, a winding system with anti-wrinkle function comprises a frame 1, an upper support 11, a lower support 12, a roll 2, a first cylinder 31, a second cylinder 32, a third cylinder 33, a fourth cylinder 34, an upper pressure roller 4, and a lower pressure roller 5. The upper support 11 and lower support 12 are fixedly installed at the upper and lower ends of the frame 1, respectively, and the roll 2 is fixedly installed in the middle of the frame. A pair of cylinder combinations, namely the first cylinder 31 and the second cylinder 32, are fixedly installed on the upper support 11. A pair of cylinder combinations, namely the third cylinder 33 and the fourth cylinder 34, are fixedly installed on the lower support 12. The upper pressure roller 4 is fixedly connected to the telescopic rods of the first cylinder 31 and the second cylinder 32. The lower pressure roller 5 is fixedly connected to the telescopic rods of the third cylinder 33 and the fourth cylinder 34. The roll 2, the upper pressure roller 4, and the lower pressure roller 5 are all horizontally arranged and parallel to each other.
[0012] When the winding machine performs the winding operation, vibrations in the winding machine motor and uneven force on the reel can cause the reel 2 to vibrate. This vibration causes irregular shaking of the wound material. The material itself also vibrates during normal operation of the production line. The curled material exerts tension on the uncurled material, and this tension amplifies the vibration amplitude caused by the operation. Vibration is the root cause of wrinkles, and the tension during winding further amplifies the vibration amplitude, thus causing irregular, large, and deep wrinkles to form on the originally flat material. These wrinkles are retained within the rolled material after winding is completed.
[0013] The winding system invented in this invention adds a set of pressure rollers in the vertical direction of the roll shaft to the original winding machine. The lower pressure roller is located at the position where the roll material curls. During winding, the pressure rollers apply pressure to the wound roll material simultaneously. The presence of the pressure rollers can fix the roll material and the roll shaft as one, reducing its irregular vibration, and at the same time isolate the shaking between the curled and uncurled roll material. This prevents the uncurled roll material from transmitting the shaking to the curled roll material during the winding action, eliminating wrinkles caused by shaking and keeping the roll material with a flat appearance.
[0014] In this embodiment, a cylinder is used as the telescopic control device. Of course, a hydraulic cylinder, an electric cylinder, or other controllable elastic telescopic device can also be used to achieve similar technical effects.
[0015] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. For some technical contents that are well known to those skilled in the art, they will not be repeated here. Those skilled in the art should understand that, based on the technical solution of the present utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the present utility model.
