Description

Technical Field

[0001] This application relates to the field of waterproof membrane production equipment, and more particularly to a coating device for the production of bituminous waterproof membranes. Background Technology

[0002] Asphalt waterproof membrane is a waterproof membrane made of high molecular polymer or rubber-modified asphalt as the coating material. It is widely used in the waterproof structure of various buildings because of its high elasticity, high temperature resistance and fatigue resistance, as well as high elongation and strong puncture resistance and tear resistance.

[0003] The production process of asphalt waterproof membrane requires a coating process. Most existing waterproof membrane coating processes are carried out by pressing. After the base layer produced in the previous process is coated with asphalt, it enters the pressing rollers together with the upper and lower membranes. The pressing rollers press the upper and lower membranes onto the base layer. Then, the coated membrane passes through a spraying mechanism, which sprays cooling water onto the coated membrane to cool it down and prevent the pressed film from shrinking, deforming, or being damaged by heat. This completes the coating process of the membrane production.

[0004] Regarding the aforementioned technologies, the inventors discovered that after the film is pressed onto the substrate, the roll material is then cooled down. After the film contacts the asphalt on the substrate, it needs to be transported forward for a certain distance to be sprayed for cooling. This results in poor timeliness of the roll material cooling, which inevitably leads to situations where the film shrinks, deforms, or is even damaged when heated during the coating process, affecting the production quality of the waterproof roll material. Summary of the Invention

[0005] To alleviate the problem that waterproof membranes are prone to shrinkage, deformation, or even damage due to insufficient cooling during the lamination process, this application provides a lamination device for the production of asphalt waterproof membranes.

[0006] This application provides a coating device for the production of asphalt waterproof membrane, which adopts the following technical solution:

[0007] A coating device for producing asphalt waterproof membrane includes a frame with multiple conveying rollers for driving the waterproof membrane. Two coating mechanisms are mounted on the frame, each applying an upper and lower membrane to a base layer. Each coating mechanism includes a film-releasing roller and a spray-pushing assembly. The film-releasing roller is rotatably connected to the frame, and the film is wound around it. The spray-pushing assembly is connected to the frame and sprays cooling water to adhere the film to the base layer.

[0008] By adopting the above technical solution, when the waterproof membrane is coated, the film is placed from the film-laying roller and kept at a certain distance from the substrate. Then, the spray-push assembly sprays cooling water onto the film, so that the film adheres to the substrate under the impact of the cooling water. This allows the film to cool down synchronously with the cooling water at the moment of contact, improving the timeliness of film cooling, reducing the possibility of coating damage due to untimely cooling, and improving the quality of the asphalt waterproof membrane.

[0009] Preferably, the spraying and pushing assembly includes a water storage tank, a first water pump, a water supply pipe, and a spraying and pushing pipe. The first water pump is disposed in the water storage tank, and the spraying and pushing pipe is fixedly connected to the frame. The spraying and pushing pipe is connected to the outlet of the first water pump through the water supply pipe. The spraying and pushing pipe has multiple outlets, all of which face the membrane.

[0010] By adopting the above technical solution, the first water pump draws water from the water storage tank, then supplies it into the spray pipe through the water supply pipe, and then sprays it out through multiple outlets. This allows the film to adhere to the base layer under the impact of the cooling water, and the cooling water can then fall back into the water storage tank, thus realizing the reuse of the cooling water.

[0011] Preferably, the water supply pipe is connected to a branch pipe, and the branch pipe is connected to a plurality of atomizing nozzles, which are used to atomize and spray the side of the film close to the membrane layer.

[0012] By adopting the above technical solution, before the film is adhered to the tire base, some of the cooling water is sprayed as water mist on the side of the film close to the tire base through multiple atomizing nozzles. This allows the film to reduce the heating rate of the film by vaporizing the water mist the moment it adheres to the tire base, thereby further reducing the possibility of heat damage to the film.

[0013] Preferably, the width of the film on the film-dispensing roller is greater than the width of the membrane layer.

[0014] By adopting the above technical solution, when the film is covered on the tire base, more film can be left on both sides of the tire base, thereby reducing the possibility that the film covering effect on the tire base edges will be affected by water ingress.

[0015] Preferably, the frame is provided with a cooling mechanism, which includes a cooling box and two guide plates. The cooling box contains cooling water, and the two guide plates are connected to the cooling box and are located on both sides of the roll material. The guide plates are used to guide the corresponding sides of the roll material. The edge film of the roll material that extends beyond the base layer is bent upward under the action of the guide plates. When the roll material enters the cooling water in the cooling box, the upwardly bent edge film is located above the surface of the cooling water.

[0016] By adopting the above technical solution, after the base layer is coated with film, the roll material is continued to be conveyed forward, which will drive the roll material into the space between two guide plates. Under the guidance of the two guide plates, the film at the edge of the roll material will gradually bend upward and then enter the cold water tank. After entering the cooling water, the roll material is submerged in the cooling tank, and the cooling water is used to cool the roll material and reduce the possibility of the film being heated again. At the same time, the film at the edge of the roll material that bends upward is above the water surface, so that the cooling water will not enter the edge of the roll material. This ensures both the cooling effect of the roll material and the quality of the rolled material after coating.

[0017] Preferably, both guide plates are slidably connected to the cooling box, and the cooling box is provided with two sets of adjustment components. The two sets of adjustment components are arranged in a one-to-one correspondence with the two guide plates. The adjustment components are connected to their corresponding guide plates to drive the two guide plates to slide in a direction that moves closer to or further away from each other.

[0018] By adopting the above technical solution, the distance between the two guide plates can be adjusted by adjusting the sliding of the component drive guide plate, thereby enabling the guide plates to guide and bend rolls of different widths and improving the applicability of the two guide plates.

[0019] Preferably, each set of adjustment components includes a screw and a guide rod. The guide rod is fixedly connected to the guide plate and slidably connected to the side wall of the cooling box. The screw is threadedly connected to the side wall of the cooling box, and one end of the screw is rotatably connected to the guide plate.

[0020] By adopting the above technical solution, the guide rod guides the movement of the guide plate, and then the operator can rotate the screw to drive the guide plate to move, thereby realizing the adjustment of the position of the guide plate.

[0021] Preferably, a cutting mechanism is provided on the frame. The cutting mechanism includes a receiving roller and two cutting elements. The receiving roller is rotatably connected to the frame and is used to support the roll material. The two cutting elements are arranged in a one-to-one correspondence with the two guide plates. The cutting elements are connected to their corresponding guide plates and are used to cut the edge film that extends beyond the base layer.

[0022] By adopting the above technical solution, after the roll material is cooled, two cutting parts are used in conjunction with receiving rollers to cut off the edge film of the roll material that extends beyond the base layer, thus avoiding excess roll material and improving aesthetics and quality.

[0023] Preferably, the frame is provided with two pressure bars, which are located on the upper and lower sides of the roll material respectively. The two pressure bars together clamp the coated roll material, and the middle part of each pressure bar protrudes forward along the direction away from the conveying direction of the roll material.

[0024] By adopting the above technical solution, the pressure bars are set to be inclined from the middle to both sides along the conveying direction of the roll material, so that the air bubbles generated after the roll material is coated can be moved to both sides of the roll material under the push of the two pressure bars, thereby expelling the air bubbles between the film and the base layer and improving the quality of the roll material coating.

[0025] Preferably, each pressure bar is hollow, and each pressure bar has multiple drainage holes on the side near the roll material. Each pressure bar is connected to a water inlet pipe, and two water inlet pipes are connected to two water supply pipes in a one-to-one correspondence. The water inlet pipe is connected to its corresponding water supply pipe.

[0026] By adopting the above technical solution, water is supplied to the inside of the pressure bar through the water inlet pipe, and then the water flows out from the drain hole of the pressure bar, thereby forming a flowing water layer between the pressure bar and the roll material. The flowing water layer can cool the roll material and reduce the possibility of the pressure bar scratching the film on the roll material, thus further ensuring the quality of the roll material.

[0027] In summary, this application includes at least the following beneficial technical effects:

[0028] 1. By setting up a spray-push assembly on the frame, when the waterproof membrane is coated, the film is placed from the film-feeding roller and kept at a certain distance from the base layer. Then, the spray-push assembly sprays cooling water onto the film, so that the film adheres to the base layer under the impact of the cooling water. This allows the film to cool down synchronously with the cooling water at the moment of contact, improving the timeliness of film cooling, reducing the possibility of coating damage due to untimely cooling, and improving the quality of the asphalt waterproof membrane.

[0029] 2. By spraying a portion of the cooling water through multiple atomizing nozzles onto the side of the film close to the tire base layer, the film can utilize the vaporization of the water mist to reduce the heating rate of the film the moment it adheres to the tire base layer, thereby further reducing the possibility of heat damage to the coating.

[0030] 3. By setting two guide plates on the frame, after the roll material is coated, the continued feeding of the roll material will cause the roll material to enter between the two guide plates. Under the guidance of the two guide plates, the film at the edge of the roll material will gradually bend upwards and then enter the cold water tank. The roll material is immersed in the cooling water, which cools the roll material and reduces the possibility of the film being heated again. At the same time, the film at the edge of the roll material that bends upwards is above the water surface, so that the cooling water will not enter the edge of the roll material. This ensures both the cooling effect of the roll material and the quality of the rolled material after coating. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0040] This application discloses a coating device for the production of asphalt waterproof membrane.

[0041] Reference Figure 1 and Figure 2 A laminating device for producing asphalt waterproof membrane includes a frame 100, on which multiple conveyor rollers 110 are rotatably connected. These conveyor rollers 110 guide and drive the membrane. Two sets of laminating mechanisms 200 are mounted on the frame 100, located on the upper and lower sides of the base layer, respectively. One set of laminating mechanisms 200 is used to press the upper membrane, and the other set is used to press the lower membrane. A pressure roller group 300 is mounted on the frame 100 to perform a secondary pressing of the laminated membrane.

[0042] Reference Figure 2 and Figure 3 Both sets of laminating mechanisms 200 have the same structure. In this embodiment, the laminating mechanism 200 located below the tire base layer is taken as an example. Each laminating mechanism 200 includes a film feeding roller 210, which is rotatably connected to the frame 100. The film is wound around the film feeding roller 210. A film receiving roller 220 is rotatably connected to the frame 100. After the film comes out of the film feeding roller 210, it passes around the film receiving roller 220 and then enters the pressing roller group 300. A spray-push assembly 230 is installed on the frame 100. The spray-push assembly 230 sprays cooling water onto the film. Under the push of the spray-push assembly 230, the film adheres to the tire base layer and then enters the pressing roller group 300 together with the tire film layer.

[0043] Reference Figure 2 , Figure 3 and Figure 4 The spraying assembly 230 includes a spraying pipe 231 fixedly connected to the frame 100. The length direction of the spraying pipe 231 is parallel to the width direction of the frame 100. Multiple water outlets are provided on the spraying pipe 231 and are spaced apart along the length direction of the spraying pipe 231. A water storage tank 232 is fixedly connected inside the frame 100. The water storage tank 232 is located below the spraying pipe 231. A first water pump 233 is installed inside the water storage tank 232. The outlet of the first water pump 233 is connected to a water supply pipe 234. The end of the water supply pipe 234 away from the first water pump 233 is connected to the spraying pipe 231. During the production of asphalt waterproof membrane, the conveying roller 110 on the frame 100 drives the asphalt-coated base film layer forward, simultaneously conveying the film on the two winding rollers forward. At this time, the film above and below the base film layer maintains a certain distance from the asphalt-coated base layer. Then, at the spraying pipe 231, water is supplied to the spraying pipe 231 by the first water pump 233 and the water supply pipe 234, causing water to spray out from multiple outlets of the spraying pipe 231. The film then adheres to the base film layer under the impact of the water flow. Since the film adheres to the base film layer under the impact of the water flow, the film can be cooled in time under the action of the water flow at the moment of adhesion, improving the timeliness of film cooling, reducing the possibility of damage to the coating due to untimely cooling, and improving the quality of the asphalt waterproof membrane.

[0044] Reference Figure 3 and Figure 4To further mitigate the possibility of instantaneous thermal shrinkage of the film, a distribution pipe 240 is connected to the water supply pipe 234. Multiple atomizing nozzles 250 are fixedly connected to the distribution pipe 240, spaced apart along its length. Each atomizing nozzle 250 is connected to the interior of the distribution pipe 240, and sprays water mist onto the side of the film closest to the tire substrate. Before the film adheres to the tire substrate, the atomizing nozzles 250 spray water mist onto the side of the film closest to the tire substrate, allowing the water mist to vaporize and reduce the film's heating rate the instant it adheres to the substrate, thereby further reducing the possibility of thermal damage to the coating.

[0045] Reference Figure 3 The width of the film on the film-spreading roller 210 is greater than the width of the tire base layer. When the film is sprayed and applied, the wider setting of the film can ensure the full coverage of the tire base layer, while reducing the possibility that water may enter the edges of the tire base layer and affect the coating effect.

[0046] Reference Figure 3 and Figure 4 The pressing roller assembly 300 includes two pressing rollers 310, both of which are rotatably connected to the frame 100. The two pressing rollers 310 are located on the upper and lower sides of the roll material, respectively. Two pressure rods 400 are fixedly connected to the frame 100, located on the upper and lower sides of the roll material, respectively. The pressure rods 400 are used to press the surface of the roll material, and the middle of each pressure rod 400 protrudes in the direction opposite to the roll material conveying. Each pressure rod 400 is hollow, and multiple drainage holes 420 are opened on the side of each pressure rod 400 near the roll material. The multiple drainage holes 420 are spaced apart along the length of the pressure rod 400. Each pressure rod 400 is connected to a water inlet pipe 410, and two water inlet pipes 410 are correspondingly set with two water supplies. The end of the water inlet pipe 410 away from the pressure rod 400 it is connected to its corresponding water inlet pipe 410. In other embodiments, a valve may be provided on the inlet pipe 410 to control the amount of water entering the pressure rod 400.

[0047] The pressure bars 400 are inclined from the middle to both sides. After the film is adhered to the base layer, it continues to be conveyed forward and passes through the pressure bars 400. The pressure of the two pressure bars 400 removes the air bubbles remaining after film coating, thereby improving the coating quality of the roll material. At the same time, water can be discharged from the drain hole 420, forming a flowing water layer between the pressure bars 400 and the roll material. The flowing water layer can cool the roll material and reduce the possibility of the film on the roll material being scratched by the pressure bars 400, further ensuring the quality of the roll material.

[0048] Reference Figure 1 and Figure 5In order to achieve complete cooling of the roll material and reduce the possibility of heat loss from incompletely cooled asphalt inside the roll material causing film deformation, a cooling mechanism 500 is installed on the frame 100. The cooling mechanism 500 includes a cooling box 510 containing cooling water. Two guide plates 520 are installed on the cooling box 510, which are located on both sides of the roll material width direction. The guide plates 520 are used to guide and bend the upper and lower films that extend beyond the base layer, so that the upper and lower films extending beyond the base layer bend upward.

[0049] Reference Figure 5 , Figure 6 and Figure 7 The guide plate 520 includes a parallel section 521, a transition section 522, and a limiting plate. The parallel section 521, transition section 522, and limiting plate 523 are arranged sequentially along the conveying direction of the roll material, and are integrally formed. The parallel section 521 is parallel to the roll material. The side of the limiting plate 523 away from the roll material is a vertically arranged plate. The side of the transition section 522 away from the other guide plate 520 gradually bends upward along the conveying direction of the roll material. The parallel section 521 smoothly transitions to the limiting plate 523 through the transition section 522. After entering the cooling box 510, the bending section bends to a horizontal state so that the roll material is in a horizontal state after entering the cooling box 510. Two limiting rollers are rotatably connected to the bending section. The rotation axis of the limiting rollers is parallel to the width direction of the roll material. The limiting rollers are used to limit the roll material to change its forward direction. Before entering the cooling tank 510, the coated roll material first passes through the guide plate 520. The guide plate 520 guides the film of the roll material that extends beyond the base layer, so that the film on both sides extending beyond the base layer can be bent upwards. Then the roll material enters the cooling tank 510. When the roll material is submerged in the cooling water in the cooling tank 510, the upwardly bent film is above the water surface, thus preventing the cooling water in the cooling tank from entering the interior of the roll material. This ensures the cooling effect of the roll material while preventing the cooling water from entering the interior of the roll material.

[0050] Reference Figure 5 and Figure 6The cooling box 510 is equipped with two sets of adjustment components 530, each corresponding to one of the two guide plates 520. Each set of adjustment components 530 includes two guide rods 531, both of which are fixedly connected to their corresponding guide plates 520. The two guide rods 531 pass through the side wall of the cooling box 510 and are slidably connected to the side wall. A screw 532 is threaded onto the side wall of the cooling box 510, with one end of the screw 532 rotatably connected to the guide plate 520. When producing rolls of different widths, rotating the screw 532 moves the two guide plates 520, thereby adjusting the distance between them. This allows the guide plates 520 to guide rolls of different widths, improving their applicability.

[0051] Reference Figure 1 and Figure 5 A cutting mechanism 600 is mounted on the frame 100. The cutting mechanism 600 includes a receiving roller 610. After the roll material exits the cooling box 510, it passes over the receiving roller 610 and continues to be conveyed forward. Each guide plate 520 is equipped with a set of cutting elements 620, which are used to cut off the upper and lower film edges of the adjacent and protruding base layer.

[0052] Each cutting component 620 includes a support rod 630, which is fixedly connected to its corresponding guide plate 520. A second motor 621 is fixedly connected to the support rod 630, and a cutting blade 622 is coaxially fixedly connected to the main shaft of the second motor 621. The cutting blade 622 is a circular blade, and the cutting blade 622 is coaxially fixedly connected to the main shaft of the second motor 621. After the waterproof membrane is cooled, the cutting blade 622 is driven to rotate by the second motor 621 to cut off the film on the membrane that extends beyond the base layer. Then, the waterproof membrane is wound up, thus completing the production of the waterproof membrane while ensuring its quality.

[0053] Reference Figure 1 and Figure 2 The cold water tank and the water storage tank 232 are connected at their closest points via a connecting pipe 511, which is equipped with an electrically controlled valve. A return water pipe 512 is connected to the end of the cold water tank furthest from the water storage tank 232, and the end of the return water pipe 512 furthest from the water storage pipe is connected to the end of the water storage tank 232 furthest from the cold water tank. A second water pump 513 is installed on the return water pipe 512, which pumps cold water from the cold water tank into the water storage tank 232. After the cooling water in the cold water tank has heated up over a period of time, the second water pump 513 is activated to draw water from the water storage tank 232 and supply it into the cold water tank. Simultaneously, the electrically controlled valve is opened to allow the heated cooling water in the cold water tank to flow back into the water storage tank 232, thus achieving the exchange of heated cooling water and ensuring the cooling effect on the roll material.

[0054] The implementation principle of the coating device for producing asphalt waterproof membrane according to this application embodiment is as follows: By setting the width of the film to be greater than the width of the substrate, when coating the substrate, the water jet from the spray pipe 231 applies a pushing force to the film, causing the film to adhere to the substrate under the push of the water jet. This allows the film to be cooled in time under the action of the water jet upon adhesion. Then, the membrane after being coated continues to be conveyed forward through two guide plates 520. The two guide plates 520 guide and limit the edges of the membrane, causing the edge of the membrane extending beyond the substrate to bend upward. This allows the edge of the membrane to bend upward before entering the cooling tank 510. When the membrane is submerged in the cooling water in the cooling tank 510, the upwardly bent edge of the membrane is above the water surface, preventing the cooling water in the cooling tank from entering the interior of the membrane, thus ensuring the quality of the membrane after coating. Finally, the excess edge of the membrane is cut off using a cutting blade 622, thus completing the membrane coating process.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
