Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane processing technology, specifically to an oil impregnation system for waterproof membranes. 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 oil impregnation process is one of the key steps that determines the performance of the membrane.

[0003] Referring to the existing Chinese patent with publication number CN215587032U, a waterproof membrane oil impregnation system is disclosed, which includes an oil impregnation tank, a first rotating roller, a second rotating roller, and an extrusion assembly; the oil impregnation tank is set on the ground; the first rotating roller and the second rotating roller are set inside the oil impregnation tank; the extrusion assembly is set inside the oil impregnation tank, located between the first rotating roller and the second rotating roller, and the extrusion assembly includes an upper extrusion roller and a lower extrusion roller, which are rotatably supported on the inner wall of the oil impregnation tank, with a small gap between them, and the base fabric passes through the lower side of the first rotating roller, between the upper extrusion roller and the lower extrusion roller, and the lower side of the second rotating roller in sequence.

[0004] The aforementioned oil-impregnation system for waterproof membranes, by immersing the base fabric in an oil-impregnation tank and squeezing it, allows the asphalt in the tank to fully impregnate the base fabric and distribute it relatively evenly, thus improving its waterproof performance. However, this system still has some drawbacks. For example, the scraper structure is used to remove excess asphalt from the surface of the base fabric to control the amount of asphalt coating and ensure surface smoothness. The scraper is a fixed flat plate structure, and the contact angle between its blade and the base fabric surface cannot be adjusted, resulting in some areas of asphalt not being completely removed, affecting subsequent processes or product quality. Utility Model Content

[0005] The purpose of this invention is to provide an oil-impregnation system for waterproof membranes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A waterproof membrane impregnation system, comprising:

[0008] An oil immersion tank is provided, with first positioning rollers rotatably connected to both ends of the oil immersion tank, two second positioning rollers rotatably connected inside the oil immersion tank, and an extrusion assembly provided inside the oil immersion tank.

[0009] The oil immersion tank is equipped with a first scraper mechanism, a second scraper mechanism, and a third scraper mechanism. Each of the three scraper mechanisms includes two scraper bodies, a servo motor, two meshing gear discs, and a rotating rod. The two scraper bodies are rotatably connected to the oil immersion tank via the rotating rod. The scraper bodies are in contact with the waterproof membrane body. The two gear discs are connected to one end of the rotating rod that passes through the oil immersion tank. The servo motor is mounted on the oil immersion tank, and its output end is connected to one of the gear discs.

[0010] Two oil-impregnated nonwoven fabric rollers are installed in the oil impregnation tank at both ends via connecting components.

[0011] Preferably, the extrusion assembly includes a rotating roller, an extrusion roller, two transverse electric slide rails and two vertical electric slide rails. The two transverse electric slide rails are installed on both sides of the oil immersion tank, the vertical electric slide rails are installed on the transverse electric slide rails, the rotating roller is rotatably connected to one end of the vertical electric slide rails, and the extrusion roller is connected between the vertical electric slide rails.

[0012] Preferably, the scraper body is provided with a plurality of electric heating wires, and a V-shaped groove is provided at one end of the scraper body.

[0013] Preferably, an mounting plate is installed on the oil immersion tank, and an infrared temperature sensor is installed on the mounting plate.

[0014] Preferably, the rotating rod has a mounting groove, and an angle sensor is installed in the mounting groove.

[0015] Preferably, the connecting assembly includes a return spring and a moving block, the oil immersion tank has a moving groove, the oil-immersed nonwoven fabric roller is rotatably connected between the moving blocks, the return spring is installed in the moving groove, and one end of the return spring is connected to the moving block.

[0016] Preferably, a controller is installed on the oil immersion tank, and the controller is electrically connected to the servo motor, the horizontal electric slide rail, the vertical electric slide rail, the electric heating wire, the infrared temperature sensor and the angle sensor respectively.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses a servo motor to drive a gear disk linkage rod, enabling flexible adjustment of the scraper body angle. Compared to the fixed flat scraper in the prior art, the scraper of this utility model can adjust the contact angle with the base fabric in real time according to the actual surface conditions. When encountering micro-undulations formed by the warp and weft yarns of the base fabric, the servo motor can precisely control the scraper angle, allowing the scraper blade to better fit the base fabric surface, thereby effectively removing excess asphalt from various areas. This significantly improves the control accuracy of asphalt coating amount and the flatness of the base fabric surface, providing a high-quality base for subsequent sand coating, film coating, and other processes. It also reduces defects such as sand particle shedding and film bubbles caused by surface unevenness, greatly improving the waterproof performance and appearance quality of the product.

[0019] 2. The first, second, and third scraper mechanisms of this utility model form a multi-stage scraping system. The three scraper mechanisms sequentially scrape the base fabric, and each scraper can be configured with different working parameters, such as contact angle and scraping force, according to actual needs. This multi-stage collaborative operation method can more thoroughly remove excess asphalt from the surface of the base fabric. Compared to single-stage scraping, it further reduces the amount of asphalt residue and ensures a more uniform distribution of asphalt on the waterproof membrane. Furthermore, the oil-impregnated nonwoven fabric roller is installed in the oil-impregnation tank via a connecting assembly, allowing for secondary impregnation and wiping of the waterproof membrane after scraping. This absorbs residual trace amounts of asphalt, further improving the oil impregnation effect and surface smoothness, reducing the frequency of manual cleaning, increasing production efficiency, and lowering production costs.

[0029] 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.

[0030] Please see Figures 1-8 This utility model provides a technical solution:

[0031] A waterproof membrane impregnation system, comprising:

[0032] An oil immersion tank 1 is provided. First positioning rollers 2 are rotatably connected to both ends of the oil immersion tank 1. Two second positioning rollers 3 are rotatably connected inside the oil immersion tank 1. An extrusion assembly is provided inside the oil immersion tank 1. The extrusion assembly includes a rotating roller 10, an extrusion roller 11, two horizontal electric slide rails 12 and two vertical electric slide rails 13. The two horizontal electric slide rails 12 are installed on both sides of the oil immersion tank 1. The vertical electric slide rails 13 are installed on the horizontal electric slide rails 12. The rotating roller 10 is rotatably connected to one end of the vertical electric slide rail 13. The extrusion roller 11 is connected between the vertical electric slide rails 13.

[0033] The waterproof membrane body 8 passes through the first positioning roller 2 and the second positioning roller 3 at both ends of the immersion tank 1, and between the rotating roller 10 and the extrusion roller 11, ensuring that the waterproof membrane body 8 is immersed in oil. Guided by the first positioning roller 2 and the second positioning roller 3, the waterproof membrane body 8 smoothly enters the immersion tank 1. The movement of the transverse electric slide rail 12 and the vertical electric slide rail 13 is controlled by the controller 23, which can precisely adjust the position of the rotating roller 10 and the extrusion roller 11. After the waterproof membrane body 8 is immersed in oil, the rotating roller 10 can assist in guiding the waterproof membrane body 8 into the space between the extrusion rollers 11. The extrusion roller 11 is connected between the vertical electric slide rails 13. When the waterproof membrane body 8 passes through the extrusion roller 11, by adjusting the distance and pressure between the extrusion roller 11 and the rotating roller 10, the immersion requirements of waterproof membrane bodies 8 with different thicknesses can be adapted, squeezing out excess asphalt while ensuring that the asphalt is evenly distributed within the waterproof membrane body 8.

[0034] The oil immersion tank 1 is equipped with a first scraper mechanism, a second scraper mechanism and a third scraper mechanism. Each of the first scraper mechanism, the second scraper mechanism and the third scraper mechanism includes two scraper bodies 4, a servo motor 5, two meshing gear disks 6 and a rotating rod 7. The two scraper bodies 4 are rotatably connected to the oil immersion tank 1 through the rotating rod 7. The scraper bodies 4 are in contact with the waterproof membrane body 8. The two gear disks 6 are connected to one end of the rotating rod 7 through the oil immersion tank 1. The servo motor 5 is installed on the oil immersion tank 1, and the output end of the servo motor 5 is connected to one of the gear disks 6.

[0035] Furthermore, the scraper body 4 is provided with several electric heating wires 14, and a V-shaped groove 15 is opened at one end of the scraper body 4. An installation plate 16 is installed on the oil immersion tank 1, and an infrared temperature sensor 17 is installed on the installation plate 16. An installation groove 18 is opened on the rotating rod 7, and an angle sensor 19 is installed in the installation groove 18.

[0036] The controller 23 starts the servo motor 5, which drives the gear disk 6 to rotate. Utilizing the stability and precision of gear transmission, the servo motor 5 drives the rotating rod 7 and the scraper body 4 to rotate, achieving flexible adjustment of the scraper angle. The first, second, and third scraper mechanisms are arranged sequentially, adjusting the scraper into three sections: a front section (coarse scraping), a middle section (fine scraping), and a rear section (polishing). Each section uses a different angle and hardness design. For example, the front scraper angle is 45° (coarse scraping of excess asphalt), the middle section is 30° (fine surface finishing), and the rear section is 15° (polishing smoothness). The electric heating wire 14 inside the scraper body 4 heats the scraper, maintaining a suitable temperature for the scraper in contact with the waterproof membrane body 8, reducing asphalt viscosity, and, combined with the guiding effect of the V-groove, improving asphalt removal efficiency.

[0037] Infrared temperature sensor 17 collects real-time surface temperature data of the waterproof membrane body 8, and angle sensor 19 monitors scraper angle information. This data is quickly transmitted to controller 23. Controller 23 analyzes and processes the data to determine whether the current production status meets the preset parameter standards. When an abnormal temperature is detected, controller 23 adjusts the power of electric heating wire 14 to restore the scraper temperature to the set range. If there is an angle deviation, controller 23 controls servo motor 5 to rotate and precisely adjust the scraper angle. If the asphalt residue does not meet the standard, controller 23 coordinates the adjustment of multiple parameters such as extrusion component pressure, scraper angle, and temperature to achieve dynamic optimization of the production process.

[0038] Two oil-impregnated nonwoven fabric rollers 9 are installed in the oil impregnation tank 1 at both ends via a connecting assembly. The connecting assembly includes a return spring 20 and a moving block 21. A moving groove 22 is provided on the oil impregnation tank 1. The oil-impregnated nonwoven fabric rollers 9 are rotatably connected between the moving blocks 21. The return spring 20 is installed in the moving groove 22, and one end of the return spring 20 is connected to the moving block 21.

[0039] Under the action of the return spring 20, the moving block 21 drives the oil-impregnated nonwoven fabric roller 9 to adhere to the surface of the waterproof membrane body 8 with constant pressure. When the thickness of the waterproof membrane body 8 changes slightly, the moving block 21 slides in the moving groove 22, so that the oil-impregnated nonwoven fabric roller 9 always maintains good contact with the surface of the waterproof membrane body 8. Through physical adsorption and wiping, the surface of the waterproof membrane body 8 is further treated.

[0040] In the above embodiment, a controller 23 is installed on the oil immersion tank 1. The controller 23 is electrically connected to the servo motor 5, the horizontal electric slide rail 12, the vertical electric slide rail 13, the electric heating wire 14, the infrared temperature sensor 17, and the angle sensor 19.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
