Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane production technology, specifically a winding device for waterproof membrane production. Background Technology

[0002] Waterproof membranes are mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist external rainwater and groundwater seepage. They are flexible building materials that can be rolled up to prevent leakage. As a leak-proof connection between the foundation and the building, they are the first line of defense for waterproofing the entire project and play a crucial role. During the production process of waterproof membranes, a winding operation is required. Most existing winding devices for waterproof membrane production also have an unwinding operation. However, during the winding process, the base strip is prone to reverse rotation due to the large tensile force. Therefore, a winding device for waterproof membrane production is designed that also has an unwinding operation, and facilitates the prevention of base strip rotation during both winding and unwinding, further ensuring unidirectional operation of winding and unwinding, and further improving the overall stability. Summary of the Invention

A fixed guide roller rotatably connected to the base frame is arranged parallel to one side of the winding roller. A movable pressure roller with an adjustable distance from the fixed guide roller is arranged parallel to one side of the fixed guide roller. Two sets of unidirectional motion mechanisms, each capable of feeding toward the fixed guide roller, are symmetrically arranged on both sides of the fixed guide roller. The two sets of unidirectional motion mechanisms move in opposite directions. Rotary slots adapted to the unidirectional motion mechanisms are provided on both sides of the fixed guide roller.

[0007] Preferably, the unidirectional motion mechanism includes an L-shaped plate, a ratchet, and ratchet teeth. A rotating shaft that engages with a rotating guide groove is rotatably connected to the L-shaped plate. The ratchet is fixedly mounted on the rotating shaft at one end away from the fixed guide roller.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] Please see Figure 1-4 A winding device for producing waterproof membrane includes a base frame 1, on which a winding roller 2 is rotatably connected. It also includes a winding and unwinding drive mechanism that can drive the winding roller 2 to rotate in both directions. A fixed guide roller 6, rotatably connected to the base frame 1, is arranged parallel to one side of the winding roller 2. A movable pressure roller 9, with an adjustable distance from the fixed guide roller 6, is arranged parallel to one side of the fixed guide roller 6. Two sets of unidirectional motion mechanisms, each capable of feeding towards the fixed guide roller 6, are symmetrically arranged on both sides of the fixed guide roller 6. The two sets of unidirectional motion mechanisms move in opposite directions. Rotary slots 15, adapted to the unidirectional motion mechanisms, are provided on both sides of the fixed guide roller 6.

[0022] Specifically, the unidirectional motion mechanism includes an L-shaped plate 11, a ratchet 12, and a ratchet tooth 13. A rotating shaft 14, which engages with the rotating slot 15, is rotatably connected to the L-shaped plate 11. The ratchet 12 is fixedly mounted on the rotating shaft 14 at one end away from the fixed guide roller 6. A ratchet tooth 13 is rotatably connected to one side of the ratchet 12 on the L-shaped plate 11, and the ratchet tooth 13 elastically abuts against the ratchet 12 through its connection with the L-shaped plate 11. The L-shaped plate 11 moves horizontally to one side of the anti-reverse frame 5 through a moving component. The moving component facilitates the overall movement of the L-shaped plate 11, ratchet 12, and ratchet tooth 13. When the rotating shaft 14 engages in the rotating slot 15, the unidirectional rotation of the anti-reverse frame 5 is ensured by the ratchet 12, the ratchet tooth 13, and the spring.

[0023] Specifically, the moving component includes an adjusting drive cylinder 17, a fixed guide roller 6 rotatably connected to the base frame 1 via an anti-reverse frame 5, an L-shaped plate 11 slidingly engaged with the anti-reverse frame 5, and symmetrical guide grooves on both sides of the anti-reverse frame 5. Each guide groove contains a sliding block 16 fixedly connected to the L-shaped plate 11 on its respective side. The adjusting drive cylinder 17 is fixedly installed on one side of the guide groove, and its output end is fixedly connected to the sliding block 16. By adjusting the drive cylinder 17, the sliding block 16 can be easily pulled and guided to slide within the guide groove, thereby driving the L-shaped plate 11, ratchet 12, ratchet tooth 13, and rotating shaft 14 to move towards or away from the anti-reverse frame 5 as a whole.

[0024] Specifically, an anti-reverse connecting frame 7 is fixedly installed on the anti-reverse frame 5. A movable frame 8 is guided and slidably fitted on the anti-reverse connecting frame 7. A movable pressure roller 9 is rotatably connected to the movable frame 8. An adjustable telescopic cylinder 10 is fixedly installed on the anti-reverse connecting frame 7. The output end of the adjustable telescopic cylinder 10 is fixedly connected to the movable frame 8. When the adjustable telescopic cylinder 10 is activated, the output shaft of the adjustable telescopic cylinder 10 extends and retracts, thereby driving the movable frame 8 and the movable pressure roller 9 to adjust the distance between themselves and the fixed guide roller 6, thus facilitating the penetration of the baseband and making it suitable for basebands of different thicknesses.

[0025] Specifically, the take-up and unwind drive mechanism includes a take-up motor 3 fixedly mounted on the base frame 1. The output shaft of the take-up motor 3 is connected to the take-up roller 2 via a transmission assembly 4. Furthermore, the transmission assembly 4 can be configured as a sprocket and chain or a belt and pulley transmission, preferably a sprocket and chain transmission. Furthermore, the take-up motor 3 is configured as a forward and reverse motor. When the take-up motor 3 is started, its output shaft rotates clockwise or counterclockwise. Through the transmission of the transmission assembly 4, the take-up roller 2 can be easily driven to rotate clockwise or counterclockwise.

[0026] Specifically, a drip tray 18 can be placed on the base frame 1 directly below the take-up roller 2. The drip tray 18 can conveniently collect the waterproof material liquid dripping from the substrate roll.
