Description

Technical Field

[0001] This utility model belongs to the field of waterproof membrane processing technology, specifically relating to a base fabric impregnation device for waterproof membrane processing. Background Technology

[0002] Waterproof membranes are now widely used in building walls, roofs, tunnels, highways, landfills, etc. After being laid, they play a role in resisting external rainwater and groundwater seepage. In the production process of waterproof membranes, the matrix needs to be impregnated in a modified asphalt tank so that the surface of the base fabric is evenly coated with a certain thickness of asphalt.

[0003] The existing patent publication number is CN215030582U, and the patent title is "A Waterproof Roll Material Impregnation Device". It includes an impregnation tank with a cover fixed on it. A smoke collection pipe is connected above the cover. An inlet and an outlet are respectively opened on both sides of the impregnation tank. A support roller is rotatably installed inside the inlet, and two leveling rollers are rotatably installed inside the outlet. An impregnation roller is rotatably installed inside the impregnation tank. A support is fixed on the cover. A scraper that abuts against the base fabric is inclinedly installed on the support. The scraper has a groove formed on it. A cleaning shovel that slides on the scraper and fits into the groove is embedded in it. A drive mechanism that drives the cleaning shovel to move is provided on the support. This utility model provides a waterproof roll material impregnation device that is environmentally friendly, adaptable to cleaning base fabrics of various specifications, and ensures the cleaning effect of the base fabric through the reciprocating motion of the cleaning shovel.

[0004] In the aforementioned prior art, the scraper can only scrape off excess asphalt on the top surface of the base fabric, and cannot make both sides of the roll material evenly coated. Excess asphalt is easily left on the bottom, resulting in poor treatment effect of the asphalt on the bottom surface by the leveling roller.

[0005] Chinese patent discloses a waterproof membrane production dip coating device (authorization announcement number CN218796921U). This patented technology uses a bidirectional screw to drive the upper and lower scrapers to move closer together synchronously. At the same time, driven by the connecting parts, the upper pressure roller moves up and down synchronously with the upper scraper. If the upper pressure roller descends, the transmission component will drive the lower pressure roller to rise, so that the two pressure rollers also move closer together. The position of the pressure rollers can be adjusted while adjusting the scraper, so that the upper and lower pressure rollers can simultaneously and evenly press the asphalt coating onto both sides of the base fabric, avoiding excess coating residue on the base fabric, and ensuring that the coating is evenly applied to both sides of the base fabric, thereby improving the production quality of the waterproof membrane.

[0006] However, it still has certain drawbacks: the coating roller is located inside the coating tank, and the fixed frame for installing the scraper is usually set at a higher height than the coating roller. This causes the running base fabric to have to travel obliquely upward after leaving the coating roller in order to pass between the upper and lower scrapers in the fixed frame. This oblique running state causes the lower surface of the base fabric to be pressed hard against the lower scraper, while the contact pressure between the upper surface of the base fabric and the upper scraper is relatively small or even there is a gap. This serious imbalance in the pressure applied to the two sides of the base fabric by the upper and lower scrapers due to the inclination of the fabric surface directly causes the coating thickness to be scraped off on both sides of the base fabric to be inconsistent, which seriously affects the uniformity of the waterproof membrane coating and the product quality. Utility Model Content

[0007] The purpose of this invention is to provide a base fabric impregnation and coating device for waterproof membrane processing, which can solve the problems mentioned in the background art.

[0008] The specific technical solution adopted in this utility model is as follows: A base fabric impregnation and coating device for waterproof membrane processing includes an impregnation and coating tank. Notches are provided on both the left and right sides of the impregnation and coating tank. Two limiting rollers are rotatably connected to the inner front and rear sides of the notches from top to bottom. An impregnation and coating roller is rotatably connected to the inner front and rear sides of the impregnation and coating tank. A C-shaped frame is fixedly connected to the front and rear edges of the upper surface of the immersion coating tank. A screw rod is threaded through the upper surface of the C-shaped frame. A C-shaped plate is rotatably connected to the lower end of the screw rod. A sliding rod is fixedly connected to the upper surface of the C-shaped plate on both the front and rear sides of the screw rod. A support frame is installed on the inner side of the C-shaped plate. Support rods are fixedly connected to the front and rear surfaces of the support frame. A leveling mechanism is provided on the upper and lower sides of the inner side of the support frame. The rear support rod is externally fixed with a gear, and the inner rear surface of the C-shaped plate is provided with a turning mechanism.

[0009] The present invention is further configured such that: the leveling mechanism includes a scraper, and an adjusting rod is rotatably connected to one side surface of the scraper.

[0010] The present invention is further configured such that: the turning mechanism includes a fixed plate, a screw rod II is threadedly connected to the upper surface of the fixed plate, a fixed block is rotatably connected to the lower end of the screw rod II, slide rod II is fixedly connected to the upper surface of the fixed block on both the left and right sides of the screw rod II, and a rack is fixedly connected to the rear end of the fixed block.

[0011] The present invention is further configured such that: the C-shaped frame is located on the right side of the dip coating roller, one end of the slide rod movably passes through the upper surface of the C-shaped frame, and the end of the support rod away from the support frame is rotatably connected to the inner surface of the C-shaped plate.

[0012] The present invention is further configured such that: the scraper is located inside the support frame, and the end of the scraper is slidably connected to the inner surface of the support frame, and the adjusting rod is threaded through one side surface of the support frame.

[0013] The present invention is further configured such that: the rear end of the fixing plate is fixedly connected to the inner rear surface of the C-shaped plate, the slide rod movably passes through the fixing plate, the rack is located on the left side of the gear, and the rack is meshed with the gear.

[0014] The technical effects achieved by this utility model are as follows: This utility model discloses a base fabric impregnation and coating device for waterproof membrane processing. By setting up a height adjustment mechanism (screw one drives the C-shaped plate and support frame to rise and fall) and an angle adjustment mechanism (screw two drives the rack and pinion gear, which in turn drives the support frame to rotate), it can adjust the height position and rotation angle of the support frame and its two scrapers. This ensures that the two scrapers are always perpendicular to the surface of the base fabric, which makes the scraping force applied to the upper and lower surfaces of the base fabric the same and uniform and controllable. It effectively solves the problem of uneven scraping caused by incorrect scraper angle or unsuitable height in traditional scraping, significantly improves the uniformity and consistency of coating removal on the surface of the base fabric, and thus ensures the uniform coating thickness and stable performance of the final waterproof membrane product.

[0017] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0018] like Figure 1 As shown, a base fabric impregnation and coating device for waterproof membrane processing includes an impregnation and coating tank 1. Notches 2 are provided on both the left and right sides of the impregnation and coating tank 1. Two limiting rollers 3 are rotatably connected from top to bottom on the inner front and rear sides of the notches 2. Impregnation and coating rollers 4 are rotatably connected on the inner front and rear sides of the impregnation and coating tank 1. The limiting roller 3 and the notch 2 are rotatably connected by a bearing; The inner surface of the dip coating roller 4 is rotatably connected to the dip coating tank 1 through a bearing. The lower surface of the dip coating roller 4 is lower than the coating liquid level. When the waterproof membrane base fabric passes through the lower surface of the dip coating roller 4, it is pressed down into the coating by the dip coating roller 4 to ensure that the base fabric is fully wetted. The waterproof membrane base fabric passes through the space between the two left limiting rollers 3, and then exits through the space between the two right limiting rollers 3; The waterproof membrane base fabric enters the dip coating tank 1 and passes through the lower surface of the dip coating roller 4 to perform dip coating treatment; The number of dip-coating rollers 4 can be set from left to right as needed.

[0019] like Figure 1-4 As shown, a C-shaped frame 5 is fixedly connected to the front and rear edges of the upper surface of the dipping tank 1. The C-shaped frame 5 is located to the right of the dipping roller 4. A screw 6 is threaded through the upper surface of the C-shaped frame 5. A C-shaped plate 7 is rotatably connected to the lower end of the screw 6. A slide rod 8 is fixedly connected to both the front and rear sides of the upper surface of the C-shaped plate 7. The slide rod 8 movably passes through the upper surface of the C-shaped frame 5. A support frame 9 is installed on the inner side of the C-shaped plate 7. A support rod 10 is fixedly connected to both the front and rear surfaces of the support frame 9. The end of the support rod 10 away from the support frame 9 is rotatably connected to the inner surface of the C-shaped plate 7. A leveling mechanism 11 is provided on both the upper and lower sides of the inner side of the support frame 9. The leveling mechanism 11 includes a scraper 12. The scraper 12 is located inside the support frame 9, and the end of the scraper 12 is slidably connected to the inner surface of the support frame 9. An adjusting rod 13 is rotatably connected to one side surface of the scraper 12. The adjusting rod 13 is threaded through one side surface of the support frame 9. A gear 14 is fixedly sleeved on the outside of the rear support rod 10. A turning mechanism 15 is provided on the inner rear surface of the C-shaped plate 7. The turning mechanism 15 includes a fixed plate 16. The rear end of the fixed plate 16 is fixedly connected to the inner rear surface of the C-shaped plate 7. A screw 17 is threaded through the upper surface of the fixed plate 16. A fixed block 18 is rotatably connected to the lower end of the screw 17. A slide rod 19 is fixedly connected to the upper surface of the fixed block 18 on both the left and right sides of the screw 17. The slide rod 19 moves through the fixed plate 16. A rack 20 is fixedly connected to the rear end of the fixed block 18. The rack 20 is located on the left side of the gear 14 and is meshed with the gear 14. The screw 6 and the C-shaped plate 7, the support rod 10 and the inner surface of the C-shaped plate 7, the adjusting rod 13 and the scraper 12, and the screw 17 and the fixing block 18 are all rotatably connected by bearings. The waterproof membrane base fabric, after being impregnated, passes between two scrapers 12 in the support frame 9, and the scrapers 12 scrape off the excess coating. The end of the scraper 12 is slidably fitted into a vertical groove on the inner surface of the support frame 9 via a slider or protrusion structure, so that the scraper 12 can slide vertically inside the support frame 9. Two scrapers 12 are symmetrically arranged on the inner side of the support frame 9, and two adjusting rods 13 are threaded through and connected to the upper and lower surfaces of the support frame 9 respectively; rotating the two adjusting rods 13 can adjust the distance between the two scrapers 12, thereby facilitating the adjustment of the scraping thickness. Rotating screw 6 can raise or lower C-shaped plate 7, thereby adjusting the height of support frame 9; Rotating screw 17 can drive rack 20 to rise and fall, thereby driving gear 14 to rotate, which in turn drives support frame 9 to rotate, so that both scrapers 12 are perpendicular to the waterproof membrane base fabric. In this state, both scrapers 12 can act on the upper and lower surfaces of the base fabric with their blades facing forward and perpendicularly, thereby ensuring that the scraping force applied to both sides of the base fabric is the same and the direction is perpendicular to the fabric surface, ultimately ensuring that the coating thickness is uniform after the excess coating is scraped off from both sides of the base fabric.

[0020] The working principle of this utility model is as follows: First, the waterproof membrane base fabric is inserted between the two limiting rollers 3 at the left notch 2 of the dipping tank 1, allowing it to enter the dipping tank 1 and pass through the lower surface of the dipping roller 4 for dipping treatment. Then, the dipped base fabric passes upwards between the upper and lower scrapers 12 inside the support frame 9 below the C-shaped frame 5. Finally, the base fabric exits between the two limiting rollers 3 at the right notch 2 of the dipping tank 1. Rotating screw 1 6 can drive the C-shaped plate 7 and the support frame 9 mounted on it to rise and fall, thereby adjusting its height. Rotating screw 2 17 drives the fixing block 18 and the rack 20 to rise and fall. 20 drives the gear 14 meshing with it to rotate, and the gear 14 drives the support rod 10 and the support frame 9 to rotate as a whole, thereby adjusting the angle of the support frame 9 and the two scrapers 12 on it, ensuring that the two scrapers 12 are perpendicular to the surface of the waterproof membrane base fabric, so that the scraping force applied to the upper and lower surfaces of the base fabric is consistent, ensuring the uniformity of the scraping thickness. Then, the two adjusting rods 13 are rotated so that the scrapers 12 respectively adhere to the two sides of the waterproof membrane base fabric, thereby scraping off the excess coating on the surface of the waterproof membrane base fabric. Finally, the traction device pulls the waterproof membrane base fabric that has completed the impregnation and scraping into the subsequent process.

[0021] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
