Description

Technical Field

[0001] This application relates to the field of material winding, and in particular to a winding device for PVC polymer waterproof membrane. Background Technology

[0002] PVC polymer waterproof membranes are widely used in waterproofing projects across numerous fields, including building construction, underground engineering, and water conservancy projects. With the increasing demand for PVC polymer waterproof membranes, their production scale is also gradually expanding. In the production process of PVC polymer waterproof membranes, the winding process is an essential step, and the quality and efficiency of winding directly affect the subsequent use and sales of the waterproof membrane. Efficient and stable winding equipment is of great significance for improving production efficiency and ensuring the quality of waterproof membranes.

[0003] Currently, traditional PVC polymer waterproof membrane winding equipment mainly consists of a frame, a winding roller rotatably connected to the frame, and a drive device to rotate the winding roller. During the winding process, the waterproof membrane is prone to shifting. When this happens, manual adjustment of the membrane's position is necessary to ensure neat winding. However, traditional PVC polymer waterproof membrane winding equipment lacks effective adjustment and limiting functions for the membrane width during winding. Manual adjustment is not only inefficient and labor-intensive, but also makes it difficult to ensure precise alignment of the wound membrane. Utility Model Content

[0004] In order to prevent the waterproof membrane from shifting during the winding process and to make the two sides of the waterproof membrane in the width direction more flat after winding, thereby improving the winding quality and efficiency, this application provides a winding device for PVC polymer waterproof membrane.

[0005] This application provides a winding device for PVC polymer waterproof membrane, which adopts the following technical solution:

[0006] A winding device for PVC polymer waterproof membrane includes a frame, a winding roller rotatably connected to the frame, and a drive device for driving the winding roller to rotate. An adjusting shaft is fixed on the frame, the adjusting shaft is located above the winding roller and its axis is parallel to the winding roller. Two symmetrically arranged and vertically extendable limiting members are slidably connected to the adjusting shaft. An adjusting mechanism is provided between the limiting members and the adjusting shaft for synchronously driving the two limiting members to move closer or further apart.

[0007] By adopting the above technical solution, when winding PVC polymer waterproof membrane, the two limiting parts are first adjusted to a position that matches the width of the waterproof membrane by adjusting the mechanism to bring them closer or further apart. Then, the limiting parts are lowered to limit the width of the waterproof membrane on both sides. Next, the drive device is started to drive the winding roller to rotate and begin winding the waterproof membrane. During the winding process, the limiting parts always limit the width of the waterproof membrane, making it less likely for the waterproof membrane to shift during winding. As a result, the width of the rolled waterproof membrane is flatter on both sides, improving the winding quality and efficiency.

[0008] Optionally, the adjustment mechanism includes two adjusting screws rotatably connected inside the adjustment shaft. The two adjusting screws are fixedly connected and have opposite thread directions. An adjustment motor is fixed to one end of the adjustment shaft, and the output shaft of the adjustment motor is fixed to the end of one of the adjusting screws.

[0009] An adjusting block is threaded onto the adjusting screw, and an adjusting groove is provided along the length of the adjusting shaft. The adjusting block is slidably connected in the adjusting groove, and the adjusting block is fixed to the limiting member.

[0010] By adopting the above technical solution, when it is necessary to adjust the distance between the two limiting members according to the waterproof membrane of different widths, the adjusting motor is started. The output shaft of the adjusting motor drives the adjusting screw fixed thereto to rotate. Since the two adjusting screws are fixedly connected and their threads turn in opposite directions, the two adjusting screws will rotate synchronously in opposite directions, causing the adjusting blocks on the two adjusting screws to slide closer or further apart in the adjusting groove of the adjusting shaft. At the same time, the adjusting blocks drive the limiting members to move closer or further apart, so as to limit the two sides of the width direction of the waterproof membrane of different widths. The adjusting mechanism can conveniently and quickly adjust the distance between the two limiting members according to the width of the waterproof membrane, so that the limiting members can be adapted to waterproof membranes of different widths, improving the versatility and applicability of the winding equipment.

[0011] Optionally, a bearing is provided between the adjusting screw and the adjusting shaft.

[0012] By adopting the above technical solution, when the adjusting motor drives the adjusting screw to rotate, the bearing enables the adjusting screw to rotate smoothly within the adjusting shaft, reducing the friction between the adjusting screw and the adjusting shaft, and avoiding the situation where the adjusting screw becomes inflexible or even jammed due to excessive friction.

[0013] Optionally, the limiting component includes a driving cylinder and a limiting plate fixed below the piston rod of the driving cylinder, with both sides of the waterproof membrane in the width direction abutting against the limiting plate.

[0014] By adopting the above technical solution, when the waterproof membrane is wound on the take-up roller, the piston rod of the drive cylinder drives the limiting plate to move downward, so that the limiting plate abuts against both sides of the waterproof membrane in the width direction, thereby restricting the position of the waterproof membrane during the winding process, preventing the waterproof membrane from shifting or wrinkling during winding, and ensuring the neatness and quality of the waterproof membrane winding; when winding is completed, the piston rod of the drive cylinder drives the limiting plate to move upward, making it easy to remove the wound waterproof membrane from the take-up roller.

[0015] Optionally, the limiting plate has an arc-shaped groove that fits against the outer circumferential surface of the take-up roller, and one side of the arc-shaped groove opening extends downward.

[0016] By adopting the above technical solution, during the winding process of PVC polymer waterproof membrane, the limiting plate is used to increase the contact area with both sides of the width direction of the rolled waterproof membrane, while the arc-shaped groove opening extends downward to facilitate the separation of the limiting plate from the winding roller when it moves upward.

[0017] Optionally, a long strip-shaped limiting rod is fixed on the side of the limiting plate away from its center, and a limiting groove is opened on the side of the limiting rods on the two limiting plates that are close to each other, and the two sides of the waterproof membrane in the width direction are respectively inserted into the limiting groove.

[0018] By adopting the above technical solution, when the waterproof membrane is wound up, both sides of the waterproof membrane in the width direction are inserted into the limiting grooves on the two limiting rods. Before the winding roller wound up the waterproof membrane, the waterproof membrane can be limited and guided in advance, making it easier and smoother for the subsequent limiting plate to limit both sides of the waterproof membrane in the width direction, and making the wound waterproof membrane less prone to wrinkles.

[0019] Optionally, a support frame is rotatably connected to the frame, and a booster cylinder is hinged between the support frame and the frame; pressure rods are spaced apart below the support frame, and multiple parallel telescopic rods are fixed between the pressure rods and the support frame; springs are sleeved on the outside of the telescopic rods, and pressure rollers are rotatably sleeved on the outside of the pressure rods along their length.

[0020] By adopting the above technical solution, when the waterproof membrane is wound on the winding roller, the pressurizing cylinder drives the support frame and pressure rod to move towards the side of the waterproof membrane, so that the pressure roller, which is rotated and sleeved on the outside of the pressure rod, comes into contact with the waterproof membrane, applying a certain tension force to the waterproof membrane during winding. Since there are multiple parallel telescopic rods fixed between the pressure rod and the support frame, and springs are sleeved on the outside of the telescopic rods, when the pressure roller applies too much pressure to the waterproof membrane, the springs will undergo elastic deformation, and the telescopic rods will extend and retract accordingly, thereby preventing the pressure roller from over-pressuring the waterproof membrane. The setting of the springs and telescopic rods ensures that the pressure roller is always in elastic contact with the surface of the waterproof membrane and applies a certain pressure to the waterproof membrane, while preventing the pressure roller from over-pressing the waterproof membrane. This makes it less likely for the waterproof membrane to become loose or wrinkled during the winding process, improving the flatness and tightness of the waterproof membrane during winding.

[0021] Optionally, a push-off seat is slidably sleeved on the take-up roller, and a drive component is provided on the frame for driving the push-off seat to move along the axial direction of the take-up roller.

[0022] By adopting the above technical solution, after winding is completed, the drive component on the frame drives the pusher seat to move along the axial direction of the winding roller. During the movement, the pusher seat will contact the wound waterproof membrane and push it to move along the axial direction of the winding roller, thereby pushing the wound waterproof membrane off the winding roller, so that the wound waterproof membrane can be easily and quickly removed from the winding roller.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During the winding process, the limiting components always limit the two sides of the waterproof membrane to prevent the membrane from shifting during winding, making the membrane winding more neat and improving winding quality and efficiency.

[0025] 2. The distance between the two limiting parts can be easily and quickly adjusted according to the width of the waterproof membrane through the adjustment mechanism, so that the limiting parts can be adapted to waterproof membranes of different widths, thereby improving the versatility and applicability of the winding equipment;

[0026] 3. When winding up the waterproof membrane, insert both sides of the waterproof membrane in the width direction into the limiting grooves on the two limiting rods. Before the winding roller winds up the waterproof membrane, it can be limited and guided in advance, making it easier and smoother for the subsequent limiting plate to limit both sides of the waterproof membrane in the width direction, and making the wound waterproof membrane less prone to wrinkles.

[0032] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0033] This application discloses a winding device for PVC polymer waterproof membrane. (Refer to...) Figure 1 and Figure 2 The PVC polymer waterproof membrane winding equipment includes a frame 1, a winding roller 2, a drive unit, an adjusting shaft 3, limiting members 4, and an adjusting mechanism 5. One end of the winding roller 2 is rotatably connected to the frame 1, while the other end is free. The drive unit, used to drive the winding roller 2 to rotate, includes a power motor fixed to the frame 1 and a gearbox connecting the power motor and the winding roller 2. The adjusting shaft 3 is fixed to the frame 1 and located above the winding roller 2, with its axis parallel to the winding roller 2. Two symmetrically arranged, vertically extendable limiting members 4 are slidably connected to the adjusting shaft 3. The adjusting mechanism 5 is used to synchronously move the two limiting members 4 closer together or further apart to accommodate waterproof membrane 6 of different widths.

[0034] When winding the PVC polymer waterproof membrane 6, the two limiting parts 4 are first moved closer or further apart according to the width of the waterproof membrane 6 by adjusting the mechanism 5 to a position that is compatible with the width of the waterproof membrane 6. Then, the limiting parts 4 are moved down to limit the width of the waterproof membrane 6 on both sides. Next, the drive device is started to drive the winding roller 2 to rotate and start winding the waterproof membrane 6. During the winding process, the limiting parts 4 always limit the width of the waterproof membrane 6, so that the waterproof membrane 6 is not easy to deviate during the winding process, and the width of the rolled waterproof membrane 6 is more flat on both sides.

[0035] Specifically, refer to Figure 3 and Figure 4The adjusting mechanism 5 includes two adjusting screws 51 rotatably connected inside the adjusting shaft 3. The two adjusting screws 51 are fixedly connected and their threads rotate in opposite directions. A bearing is provided between the adjusting screws 51 and the adjusting shaft 3 to reduce the friction between them and improve the smoothness of the adjustment. An adjusting motor 52 is fixed to one end of the adjusting shaft 3, and the output shaft of the adjusting motor 52 is fixed to the end of one of the adjusting screws 51. An adjusting block 53 is threaded onto the adjusting screw 51 and is fixed to the limiting member 4. An adjusting groove 31 is formed along the length of the adjusting shaft 3, and the adjusting block 53 is slidably connected within the adjusting groove 31.

[0036] When it is necessary to adjust the distance between the two limiting members 4 according to the different widths of the waterproof membrane 6, the adjusting motor 52 is started. The output shaft of the adjusting motor 52 drives the adjusting screw 51 fixed thereto to rotate. Since the two adjusting screws 51 are fixedly connected and the threads turn in opposite directions, the two adjusting screws 51 will rotate synchronously in opposite directions, causing the adjusting blocks 53 on the two adjusting screws 51 to slide closer or further away from each other in the adjusting groove 31 of the adjusting shaft 3. At the same time, the adjusting blocks 53 drive the limiting members 4 to move closer or further away from each other, so as to limit the width of the waterproof membrane 6 on both sides.

[0037] Specifically, refer to Figure 2 and Figure 3 The limiting component 4 includes a driving cylinder 41 and a limiting plate 42 fixed below the piston rod of the driving cylinder 41. The two sides of the waterproof membrane 6 in the width direction abut against the limiting plate 42. The limiting plate 42 is used to increase the contact area with the two sides of the waterproof membrane 6 in the width direction after it is rolled up. The limiting plate 42 has an arc-shaped groove 421 that fits against the outer peripheral surface of the take-up roller 2. The opening side of the arc-shaped groove 421 extends downward. The downward extension of the opening side of the arc-shaped groove 421 is used to facilitate the separation of the limiting plate 42 from the take-up roller 2 when it moves upward. A long strip-shaped limiting rod 43 is fixed on the side of the limiting plate 42 away from its center. A limiting groove 431 is opened on the side of the limiting rod 43 on the two limiting plates 42 that are close to each other. The two sides of the waterproof membrane 6 in the width direction are respectively inserted into the limiting groove 431. Before the winding roller 2 winds up the waterproof membrane 6, the waterproof membrane 6 can be limited and guided in advance, so that the limiting plate 42 can limit the two sides of the waterproof membrane 6 in the width direction more easily and smoothly, and the waterproof membrane 6 after winding is less likely to wrinkle.

[0038] Reference Figure 1 and Figure 2 A push-off seat 7 is slidably sleeved on the take-up roller 2. A drive component 71 is provided on the frame 1 to drive the push-off seat 7 to move along the axial direction of the take-up roller 2. The drive component 71 includes a linear motor fixed on the frame 1. The slider of the linear motor is fixed to the push-off seat 7. The slider of the linear motor moves in a direction parallel to the axis of the take-up roller 2.

[0039] When the waterproof membrane 6 is wound on the take-up roller 2, the piston rod of the drive cylinder 41 drives the limiting plate 42 to move downward, so that the limiting plate 42 abuts against both sides of the waterproof membrane 6 in the width direction, restricting the position of the waterproof membrane 6 during the winding process, preventing the waterproof membrane 6 from shifting or wrinkling during winding, and ensuring the neatness and quality of the winding of the waterproof membrane 6. After winding is completed, the piston rod of the drive cylinder 41 drives the limiting plate 42 to move upward, and the linear motor drives the pusher seat 7 to move axially along the take-up roller 2, pushing the wound waterproof membrane 6 off the take-up roller 2.

[0040] Reference Figure 2 and Figure 3 A support frame 8 is rotatably connected to the frame 1, and a booster cylinder 81 is hinged between the support frame 8 and the frame 1. Pressure rods 82 are spaced apart below the support frame 8, and multiple parallel telescopic rods 83 are fixed between the pressure rods 82 and the support frame 8. Springs 84 are sleeved on the outside of the telescopic rods 83, and pressure rollers 85 are rotatably sleeved on the outside of the pressure rods 82 along their length.

[0041] When the waterproof membrane 6 is wound on the take-up roller 2, the booster cylinder 81 drives the support frame 8 and the pressure rod 82 to move towards the side of the waterproof membrane 6, so that the pressure roller 85, which is rotatably sleeved on the outside of the pressure rod 82, comes into contact with the waterproof membrane 6, applying a certain tension force to the waterproof membrane 6 during winding. Since there are multiple parallel telescopic rods 83 fixed between the pressure rod 82 and the support frame 8, and springs 84 are sleeved on the outside of the telescopic rods 83, when the pressure roller 85 applies too much pressure to the waterproof membrane 6, the springs 84 will undergo elastic deformation, and the telescopic rods 83 will extend and retract accordingly, thereby preventing the pressure roller 85 from over-pressing the waterproof membrane 6, making it less likely for the waterproof membrane 6 to become loose or wrinkled during the winding process, and improving the flatness and tightness of the waterproof membrane 6 during winding.

[0042] The implementation principle of a PVC polymer waterproof membrane winding device according to an embodiment of this application is as follows: When winding the PVC polymer waterproof membrane 6, the position of the limiting member 4 is first flexibly adjusted according to the width of the waterproof membrane 6 by the adjusting mechanism 5 to accurately position the width of the waterproof membrane 6. Then, the piston rod of the driving cylinder 41 drives the limiting plate 42 to move downward, so that the limiting plate 42 abuts against both sides of the waterproof membrane 6 in the width direction, limiting the waterproof membrane 6 during the winding process to prevent the waterproof membrane 6 from deviating during winding. Then, the driving device is started to drive the winding roller 2 to rotate and start winding the waterproof membrane 6. During the winding process, the limiting member 4 always limits both sides of the waterproof membrane 6, so that the waterproof membrane 6 is not easy to deviate during the winding process, making the two sides of the width direction of the rolled waterproof membrane 6 more flat. At the same time, during the winding process, the pressure roller 85 contacts the waterproof membrane 6, applying a certain tension force to the waterproof membrane 6 during winding, making the rolled waterproof membrane 6 more compact and improving the winding quality.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
