Abstract
Description
Technical Field
[0001] This utility model is an auxiliary device for cooling and shaping waterproof membrane, belonging to the technical field of waterproof membrane processing equipment. 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 vital role in the overall project. In the production process of waterproof membranes, the base fabric that has completed the oil impregnation process needs to be cooled and shaped. Poor cooling and shaping results in uneven thickness and deformation of the waterproof membrane. Most existing methods for cooling and shaping waterproof membranes use water cooling, followed by heating and drying after cooling.
[0003] However, when drying directly, the heat source comes into direct contact with the roll material, which can easily lead to excessively high local temperatures, causing the roll material surface to burn or the internal structure to be damaged. Direct heating may also cause uneven heating of the roll material, with some areas overheating while other areas are not completely dry, affecting product quality. There is an urgent need for a waterproof roll material cooling and shaping auxiliary device to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an auxiliary device for cooling and shaping waterproof membranes, thereby solving the problems mentioned in the background section. This invention can cool and shape waterproof membranes, and the subsequent modular box structure allows for indirect heating and drying, preventing the waterproof membranes from directly contacting the heat source and ensuring uniform heating to guarantee the quality of the waterproof membranes.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling and shaping auxiliary device for waterproof roll material, comprising a cooling and shaping box and a heat-insulating outer frame. The cooling and shaping box contains cooling water, and two first limiting rollers are installed adjacent to each other in the cooling water. The upper left and right sides of the cooling and shaping box are respectively provided with an inlet and an outlet, and two first guide rollers and two second limiting rollers are respectively installed at the lower ends of the inlet and outlet. The heat-insulating outer frame is located on the upper right side of the cooling and shaping box, and a sponge cleaning frame is embedded at the right end of the heat-insulating outer frame. The lower end of the frame is connected to the outlet. Inside the heat-insulating outer frame, the upper left end and the lower right end are respectively fixed with a first conical box and a second conical box. The inclined surfaces of the first conical box and the second conical box are respectively fixed with a first flow equalization plate and a second flow equalization plate. The inclined surface of the first flow equalization plate is fixed with a first metal roller. The inclined surface of the second flow equalization plate is fixed with two second metal rollers. The front ends of the first conical box and the second conical box are both equipped with conical ventilation pipes. The front ends of the two conical ventilation pipes are connected and fixed with an installation frame. The front end of the installation frame is equipped with a fan and a disc heating tube.
[0006] Furthermore, the lower left and right sides of the heat-insulating outer frame are fixed with module support legs, and the upper right side of the cooling and shaping box has two positioning grooves.
[0007] Furthermore, the two module legs are respectively engaged in two positioning slots.
[0008] Furthermore, a waterproof membrane body is inserted between the two first guide rollers, the two first limit rollers, the two second limit rollers, the two first metal rollers, the second metal rollers, and the sponge cleaning frame.
[0009] Furthermore, the fan and the disc heating element are connected to an external PLC controller via wires.
[0010] Furthermore, a drain pipe is installed through the lower front end of the cooling and shaping box.
[0011] The beneficial effects of this utility model are as follows: This utility model provides a cooling and shaping auxiliary device for waterproof membranes.

Detailed Implementation
[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] Please see Figures 1-3This utility model provides a technical solution: a cooling and shaping auxiliary device for waterproof roll material, including a cooling and shaping box 1 and a heat-insulating outer frame 18. The cooling and shaping box 1 contains cooling water 2, and two first limiting rollers 3 are installed adjacent to each other in the cooling water 2. The upper left and right sides of the cooling and shaping box 1 are respectively provided with an inlet and an outlet, and two first guide rollers 5 and two second limiting rollers 6 are respectively installed at the lower ends of the inlet and outlet. The heat-insulating outer frame 18 is located on the upper right side of the cooling and shaping box 1. A sponge cleaning frame 17 is embedded in the right end of the heat-insulating outer frame 18, and the lower end of the heat-insulating outer frame 18 communicates with the outlet. The upper left and lower right ends of the interior of the heat-insulating outer frame 18 are also connected. A first conical box 19 and a second conical box 10 are fixed to the ends respectively. A first air distribution plate 7 and a second air distribution plate 11 are fixed to the inclined surfaces of the first conical box 19 and the second conical box 10 respectively. A first metal roller 8 is fixed to the inclined surface of the first air distribution plate 7. Two second metal rollers 9 are fixed to the inclined surface of the second air distribution plate 11. Conical ventilation pipes 16 are installed at the front ends of the first conical box 19 and the second conical box 10. The front ends of the two conical ventilation pipes 16 are connected and fixed to an installation frame 13. A fan 14 and a disc heating pipe 15 are installed at the front end of the installation frame 13. This design solves the problem of poor drying effect when the original waterproof membrane is directly heated after cooling.
[0019] As the first embodiment of this utility model: Modular support legs 12 are fixed to the left and right sides of the lower end of the thermal insulation outer frame 18. Two positioning grooves are opened on the upper right side of the cooling and shaping box 1, and the two modular support legs 12 are respectively inserted into the two positioning grooves. By adding the two modular support legs 12 and inserting them into the two positioning grooves, the thermal insulation outer frame 18 can be accurately and stably placed. A waterproof membrane body 4 is inserted between the two first guide rollers 5, the two first limiting rollers 3, the two second limiting rollers 6, the two first metal rollers 8, the second metal rollers 9, and the sponge cleaning frame 17. The addition of the two first guide rollers 5, the two first limiting rollers 3, and the two second limiting rollers 6 facilitates the guidance and cooling and shaping of the waterproof membrane body 4 entering the cooling and shaping box 1. Furthermore, the arrangement of the two first metal rollers 8, the second metal rollers 9, and the sponge cleaning frame 17 facilitates the indirect heating, drying, and wiping of the waterproof membrane body 4.
[0020] The fan 14 and the disc heating element 15 are connected to an external PLC controller via wires. The fan 14, disc heating element 15, and external PLC controller are existing mature components, and their working principle is known to those skilled in the art, so it will not be described in detail. A drain pipe is installed through the lower front end of the cooling and shaping box 1, which facilitates the drainage and replacement of the cooling water 2 inside the cooling and shaping box 1.
[0021] As a second embodiment of this utility model: the waterproof membrane body 4 is passed sequentially from left to right through two first guide rollers 5, two first limiting rollers 3, two second limiting rollers 6, two first metal rollers 8, a second metal roller 9, and a sponge cleaning frame 17, and is wound up and transported from left to right. During this process, the waterproof membrane body 4, which is in contact with cooling water 2 between the two first limiting rollers 3, is cooled and shaped. Then, the cooled and shaped waterproof membrane body 4 enters between the two first metal rollers 8 and the second metal rollers 9. The fan 14 and the disc heating pipe 15 are started. The fan 14 draws in outside air and heats it through the disc heating pipe 15, and then it enters the first conical ventilation pipe through two conical ventilation pipes 16. Inside the first conical box 19 and the second conical box 10, heating is achieved. At the same time, hot air is heated by the air holes of the first uniform air plate 7 and the second uniform air plate 11. The two first metal rollers 8 and the second metal rollers 9 are heated by the two first metal rollers 8 and the second metal rollers 9. The two first metal rollers 8 and the second metal rollers 9 then heat the waterproof membrane body 4 at that point. Meanwhile, some excess hot air is blown into the waterproof membrane body 4 inside the heat insulation outer frame 18. This achieves uniform heating and drying of the waterproof membrane body 4. Finally, the waterproof membrane body 4, after being uniformly heated and dried, is wiped clean by passing through the sponge cleaning frame 17. This prevents residual moisture from adhering to the surface of the waterproof membrane body 4 and ensures the subsequent winding quality of the waterproof membrane body 4.
