[0020] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0021] Please see Figure 1-5 This utility model provides a waterproof membrane sealing device, including a sealing device body 1, a pressing plate 2, and a pressing roller structure 3. The pressing plate 2 is installed on the lower right side of the sealing device body 1. The lower left side of the pressing plate 2 is designed with an arc shape to reduce damage to the waterproof membrane. The pressing roller structure 3 is installed on the lower left side of the sealing device body 1. The pressing roller structure 3 includes a pressing roller 31, a groove 32, a threaded groove 33, a disassembly structure 34, and a bearing seat 35. The upper end face of the pressing roller 31 has a groove 32 in the middle. The upper end face of the groove 32 has threaded grooves 33 on both the front and rear sides. Furthermore, the grooves 32 and threaded grooves 33 are arranged in a circular array around the center of the pressure roller 31. The inner wall of the groove 32 fits against the disassembly and assembly structure 34. The front and rear ends of the pressure roller 31 are rotatably connected to the bearing seat 35. The upper end face of the bearing seat 35 is installed and connected to the sealing device body 1. The disassembly and assembly structure 34 includes an arc-shaped block 341, a protrusion 342, a circular groove 343, a guide groove 3444, and a screw 345. The lower end face of the arc-shaped block 341 is equipped with a protrusion 342. Circular grooves 343 are opened on both the front and rear sides of the upper end face of the arc-shaped block 341, and the arc-shaped block 341 and the protrusion 342 are along the circular grooves 3444. Guide grooves 3444 are respectively opened along the central axis of the arc-shaped block 341. Circular grooves 343 are evenly distributed at the four corners of the upper end face of the arc-shaped block 341 to ensure uniform force distribution. The lower inner wall of the guide groove 344 is provided with a thread that matches the threaded groove 33. The threaded groove 33 is threadedly connected to the screw 345. The protrusion 342 fits against the inner wall of the groove 32. The outer side of the arc-shaped block 341 is polished to reduce friction with the waterproof membrane and improve the edge sealing quality. The arc-shaped block 341 and the protrusion 342 have a modular structure, which facilitates the assembly of the arc-shaped block 341 and the protrusion 342. The replacement of 2 facilitates the insertion and mating of the protrusion 342 and the groove 32. A spring washer is added between the screw 345 and the circular groove 343 to prevent loosening. The spring washer prevents loosening by increasing the friction between the screw and the connector. When the screw is tightened, the corrugated or toothed part of the spring washer will deform and generate elastic force. When subjected to preload, it will produce elastic deformation, thereby generating additional friction between the screw and the connector. The screw 345 is made of magnetic material (304 stainless steel) to facilitate adsorption and positioning during disassembly and assembly, and prevent loss.

[0022] The working principle is as follows:

[0023] First, the staff moved the new device to the required position and clamped the hydraulic cylinder and spray gun at the carrying tube and spray gun clamp of the sealing device body 1 respectively. The spray gun was tilted so that the nozzle was facing the waterproof membrane. After the waterproof membrane was laid, the waterproof membrane was heat-melted by the spray gun and the hydraulic cylinder. The entire device was moved by the handle of the sealing device body 1 so that the arc block 341 squeezed out the heat-melted grease of the waterproof membrane. The pressing plate 2 was used to flatten the waterproof membrane so that it was bonded to the ground.

[0024] After prolonged use, the arc-shaped block 341 will wear down due to the continuous pressure it exerts on the waterproof membrane. The screws 345 at the severely worn arc-shaped block 341 will be removed, releasing its restraint. By removing the arc-shaped block 341, the protrusion 342 will move, separating from the groove 32. Because the arc-shaped block 341 and protrusion 342 are modularly designed, they can be easily replaced. Furthermore, by grouping the arc-shaped blocks 341, they can be replaced according to their wear condition, avoiding the need for complete replacement, thus reducing costs and improving usability.
