Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproof membrane impregnation, specifically an extrusion device for waterproof membrane impregnation. Background Technology
[0002] Extrusion equipment for waterproof membrane impregnation is a core component of the membrane production line. It is defined as a set of precision rollers. Its main function is to uniformly extrude and scrape off excess coating by precisely controlling the pressure between the rollers after the membrane base fabric is impregnated with coating, thereby ensuring that the membrane coating is uniform in thickness, dense and free of bubbles, and meets the predetermined unit area quality requirements.
[0003] In existing technologies, extrusion equipment for waterproof membrane impregnation can ensure that the membrane coating is uniform in thickness, dense, and free of air bubbles, achieving the predetermined unit area quality requirements. However, during the extrusion of the base fabric, some of the asphalt adhering to the base fabric remains on the roller surface. As the equipment operates for a period of time, more and more asphalt adheres to the roller surface. After cooling, the asphalt hardens and forms granules. These asphalt particles may cause holes or leaks on the surface of the base fabric. To address this, workers typically stop the equipment periodically and use tools to scrape off the asphalt particles from the roller surface, thus preventing the particles from easily becoming trapped. While this method can effectively scrape off asphalt particles, it requires stopping the equipment during the scraping process, which may affect work efficiency. Furthermore, the method of stopping the machine for cleaning makes it difficult to guarantee that the equipment can be stopped and the roller surface cleaned at any time. This may result in some asphalt particles not being cleaned in time, potentially affecting product yield. Additionally, if the scraped asphalt particles and other foreign matter are not cleaned up promptly, they may contaminate the working environment, requiring additional cleaning by staff and wasting considerable time. Utility Model Content
[0004] To compensate for the shortcomings of existing technology, the equipment needs to be stopped during the scraping process. However, stopping the machine may affect work efficiency. Furthermore, it is difficult to guarantee that the equipment can be stopped and the roller surface cleaned at any time using the stop-and-clean method. As a result, some asphalt particles may not be cleaned up in time, which may affect the product yield. If the scraped asphalt particles and other foreign objects are not cleaned up in time, they may also pollute the working environment. This requires workers to clean the ground extra, which wastes a lot of time.
[0005] The technical solution adopted by this utility model to solve its technical problem is: an extrusion device for waterproof membrane impregnation, including an extrusion equipment body, a connecting base plate fixedly connected to one side of the extrusion equipment body, an extrusion roller body provided in the inner cavity of the extrusion equipment body, two extrusion roller bodies provided, a cleaning mechanism provided at the top of the connecting base plate, and a storage mechanism provided at the bottom of the connecting base plate. The cleaning mechanism includes a cylinder, the bottom of which is fixedly connected to the top of a connecting base plate. A movable plate is fixedly connected to the output end of the cylinder. The bottom of the movable plate is slidably connected to the top of the connecting base plate. A mounting side plate is fixedly connected to the top of the movable plate. A servo motor is fixedly connected to the inner cavity of the mounting side plate. The output end of the servo motor passes through one side of the mounting side plate and is fixedly connected to a rotating rod. A nylon brush is fixedly connected to one end of the rotating rod. The surface of the nylon brush is movably connected to the surface of the extrusion roller body.
[0006] Preferably, the storage mechanism includes a temporary storage box, one side of which is fixedly connected to one side of the connecting base plate. A sliding plate is fixedly connected to the inner cavity of the temporary storage box, and a baffle is fixedly connected to one side of the sliding plate. A storage box is movably connected to one side of the sliding plate and the baffle.
[0007] Preferably, the top of the connecting base plate is provided with a sliding groove, and the bottom of the movable plate is fixedly connected with a sliding block, the surface of the sliding block being slidably connected to the inner cavity of the sliding groove.
[0008] Preferably, a support block is rotatably connected to the surface of the rotating rod, a reinforcing block is fixedly connected to the surface of the support block, and the bottom of the reinforcing block is fixedly connected to the top of the connecting base plate.
[0009] Preferably, an extension plate is fixedly connected to the top of the temporary storage box, and two extension plates are provided, both of which are the same size.
[0010] Preferably, the inner cavity of the temporary storage box is fixedly connected to an inclined plate, the top of the inclined plate is fixedly connected to a guide block, and one side of the guide block is fixedly connected to the inner cavity of the temporary storage box.
[0011] Preferably, the inner cavity of the storage box is movably connected to a receiving box, and a handle is fixedly connected to one side of the receiving box.
[0012] Preferably, a snap-fit groove is provided on one side of the storage box, and a snap-fit limiting plate is movably snapped into the inner cavity of the snap-fit groove.
[0013] The advantages of this utility model are: This invention utilizes a servo motor to drive a rotating rod and a nylon brush. The rotation of the nylon brush scrapes off asphalt particles and other foreign matter from the surface of the extrusion roller. A temporary storage box, a sliding plate, and a storage box work together to collect the scraped asphalt particles and other foreign matter. The cleaning mechanism allows for real-time cleaning of the extrusion roller, preventing the residue of large amounts of asphalt particles and other foreign matter from remaining on its surface. This eliminates the need for frequent machine shutdowns, improving work efficiency. The collection mechanism also collects and recycles the scraped particles, solving the problems of needing to stop the machine during the scraping process, which can impact work efficiency. Furthermore, the traditional stop-and-clean method makes it difficult to ensure the machine can be stopped and the roller surface cleaned at any time, potentially resulting in some asphalt particles not being removed in time, thus affecting product yield. Additionally, if the scraped asphalt particles and other foreign matter are not cleaned promptly, they can pollute the working environment, requiring additional cleaning and wasting considerable time.

Detailed Implementation
[0017] 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 scope of protection of the present utility model.
[0018] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail. Example 1 like Figure 1 , Figure 2 and Figure 3 As shown in the embodiment of this application, an extrusion device for waterproof membrane impregnation is disclosed, including an extrusion equipment body 1, a connecting base plate 2 fixedly connected to one side of the extrusion equipment body 1, an extrusion roller body 16 provided in the inner cavity of the extrusion equipment body 1, two extrusion roller bodies 16 provided, a cleaning mechanism 3 provided at the top of the connecting base plate 2, and a storage mechanism 4 provided at the bottom of the connecting base plate 2. The cleaning mechanism 3 includes a cylinder 301. The bottom of the cylinder 301 is fixedly connected to the top of the connecting base plate 2. A movable plate 302 is fixedly connected to the output end of the cylinder 301. The bottom of the movable plate 302 is slidably connected to the top of the connecting base plate 2. A mounting side plate 303 is fixedly connected to the top of the movable plate 302. A servo motor 304 is fixedly connected to the inner cavity of the mounting side plate 303. The output end of the servo motor 304 passes through one side of the mounting side plate 303 and is fixedly connected to a rotating rod 305. A nylon brush 306 is fixedly connected to one end of the rotating rod 305. The surface of the nylon brush 306 is movably connected to the surface of the extrusion roller body 16.
[0019] The extrusion equipment body 1 can provide installation and connection for the connecting base plate 2 and the extrusion roller body 16. At the same time, the extrusion equipment body 1 can use the huge pressure and precise gap between the extrusion roller bodies 16 to forcibly squeeze out excess paint, remove internal air bubbles, and compact and shape the coated roll material as it passes through, thereby precisely controlling the thickness, density and penetration of the roll material. The extrusion equipment body 1 is existing technology in this field, so it will not be described in detail here. Furthermore, the connecting base plate 2 provides installation and connection for the cylinder 301. The cylinder 301 is also connected to the movable plate 302. Operators can activate the cylinder 301, which in turn moves the movable plate 302. The movable plate 302 provides installation and connection for the mounting side plate 303. The mounting side plate 303 is connected to the servo motor 304 and the rotating rod 305. Operators can activate the servo motor 304, which in turn rotates the rotating rod 305. 5 is connected to the nylon brush 306. When the rotating rod 305 rotates, it will drive the nylon brush 306 to rotate synchronously. The nylon brush 306 can scrape off the asphalt particles and other foreign objects adhering to the surface of the extrusion equipment body 1 through its own rotation, so that the asphalt particles are not easy to adhere to the surface of the extrusion equipment body 1. This eliminates the need for the operator to frequently stop the equipment and manually scrape off the asphalt particles remaining on the surface of the extrusion equipment body 1. At the same time, there are two cleaning mechanisms 3. The two cleaning mechanisms 3 have the same structure, so they will not be described in detail here.
[0020] Reference Figure 2 and Figure 3 The top of the connecting base plate 2 is provided with a sliding groove 5, and the bottom of the movable plate 302 is fixedly connected with a sliding block 6. The surface of the sliding block 6 is slidably connected to the inner cavity of the sliding groove 5. The movable plate 302 can provide installation and connection for the sliding block 6. By providing a sliding groove 5 on the surface of the connecting base plate 2, the sliding block 6 can slide in the inner cavity of the sliding groove 5. The setting of the sliding groove 5 and the sliding block 6 can limit the movement of the movable plate 302, making the movement of the movable plate 302 smoother and less prone to deviation.
[0021] Reference Figure 2 and Figure 3 A support block 7 is rotatably connected to the surface of the rotating rod 305, and a reinforcing block 8 is fixedly connected to the surface of the support block 7. The bottom of the reinforcing block 8 is fixedly connected to the top of the connecting base plate 2. The movable plate 302 can provide installation and connection for the reinforcing block 8. The reinforcing block 8 is connected to the support block 7, and the support block 7 is connected to the rotating rod 305. The reinforcing block 8 can provide reinforcement for the support block 7, so that the support block 7 can better support and limit the rotating rod 305, and at the same time, the rotating rod 305 can be used more smoothly.
[0022] Working Principle: Before use, the operator can start the servo motor 304, which drives the rotating rod 305 to rotate. When the rotating rod 305 starts rotating, it drives the nylon brush 306 to rotate synchronously. The nylon brush 306 can scrape off the asphalt particles and other foreign objects remaining on the surface of the extrusion roller body 16 through its own rotation, making it less likely for asphalt particles to remain on the surface of the extrusion roller body 16. This eliminates the need for the operator to frequently stop the equipment and clean the surface of the extrusion roller body 16. At the same time, over time, the extrusion roller body 16 may become smaller due to wear. In order to keep the nylon brush 306 in contact with the extrusion roller body 16, the operator can start the cylinder 301, which drives the moving plate 302 to move. The moving plate 302 drives the nylon brush 306 to move synchronously, thus keeping the nylon brush 306 in contact with the extrusion roller body 16 and successfully scraping off the particles and other foreign objects on the surface of the extrusion roller body 16.
[0023] Example 2 like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the storage mechanism 4 includes a temporary storage box 401. One side of the temporary storage box 401 is fixedly connected to one side of the connecting base plate 2. A sliding plate 402 is fixedly connected to the inner cavity of the temporary storage box 401. A baffle 403 is fixedly connected to one side of the sliding plate 402. A storage box 404 is movably connected to one side of the sliding plate 402 and the baffle 403. The connecting base plate 2 provides installation and connection for the temporary storage box 401. The temporary storage box 401 can collect foreign objects such as asphalt particles scraped off by the nylon brush 306, thus preventing the particles from directly scattering below the workbench and polluting the working environment. The temporary storage box 401 provides installation and connection for the sliding plate 402 and the baffle 403. The interior of the temporary storage box 401 is interconnected with one side of the sliding plate 402 and the baffle 403. When particles fall into the interior of the temporary storage box 401... The particles will flow out of the temporary storage box 401 through the sliding plate 402, while the baffle 403 can block the particles passing through the sliding plate 402, allowing them to move smoothly along the surface of the sliding plate 402. Both the sliding plate 402 and the baffle 403 are connected to the inside of the storage box 404, so that the particles inside the temporary storage box 401 can flow into the storage box 404 through the sliding plate 402 and be collected by the storage box 404. Every once in a while, the staff can clean and recycle the particles inside the storage box 404. The setting of the collection mechanism 4 can effectively avoid the pollution of the working environment by foreign objects such as asphalt particles, and at the same time, it can collect and reuse the particles, saving production costs to a certain extent. There are two collection mechanisms 4, and the two collection mechanisms 4 have the same structure, so they will not be described in detail here.
[0024] Reference Figure 4 and Figure 7 The top of the temporary storage box 401 is fixedly connected to an extension plate 9. There are two extension plates 9, and the two extension plates 9 are the same size. The temporary storage box 401 can provide installation and connection for the extension plates 9. The extension plates 9 can expand the receiving area of the temporary storage box 401 for foreign objects such as asphalt particles, so that the foreign objects scraped off by the nylon brush 306 can fall smoothly into the interior of the temporary storage box 401, thus making it less likely for foreign objects to fall directly to the ground and pollute the working environment. The fact that the two extension plates 9 are the same size can make the receiving area of the temporary storage box 401 more uniform, so that foreign objects such as particles can be received by the temporary storage box 401 more smoothly.
[0025] Reference Figure 4 and Figure 5An inclined plate 10 is fixedly connected to the inner cavity of the temporary storage box 401. A guide block 11 is fixedly connected to the top of the inclined plate 10. One side of the guide block 11 is fixedly connected to the inner cavity of the temporary storage box 401. The temporary storage box 401 can provide installation and connection for the inclined plate 10 and the guide block 11. The inclined plate 10 can allow foreign objects such as asphalt particles falling into the temporary storage box 401 to slide smoothly to one side of the temporary storage box 401 through its own inclined surface. The guide block 11 can prevent foreign objects such as asphalt particles inside the temporary storage box 401 from accumulating in the corners of the temporary storage box 401 and allow the particles to flow more smoothly into the surface of the sliding plate 402.
[0026] Reference Figure 6 and Figure 7 The storage box 404 is movably connected to a collection box 12. A handle 13 is fixedly connected to one side of the collection box 12. The storage box 404 is connected to the collection box 12, and the collection box 12 provides a mounting and connection function for the handle 13. When foreign objects such as asphalt particles enter the interior of the storage box 404, they will fall directly into the interior of the collection box 12 and be collected by the collection box 12. When the staff needs to clean the foreign objects such as asphalt particles inside the storage box 404, they only need to pull the handle 13 to disengage the collection box 12 from the storage box 404. The setting of the collection box 12 and the handle 13 makes it easier and more convenient for the staff to clean the foreign objects such as asphalt particles inside the storage box 404.
[0027] Reference Figure 6 and Figure 7 A snap-fit groove 14 is provided on one side of the storage box 404. A snap-fit limiting plate 15 is movably snapped into the inner cavity of the snap-fit groove 14. When the staff places the storage box 12 inside the storage box 404, the snap-fit limiting plate 15 can be inserted into the snap-fit groove 14. After the snap-fit limiting plate 15 is inserted into the snap-fit groove 14, it can limit the storage box 12, making it difficult for the storage box 12 to move due to external reasons such as vibration. As a result, the storage box 12 cannot easily catch all the foreign objects such as asphalt particles that flow into the storage box 404, which will require the staff to clean up the foreign objects such as asphalt particles that fall into the storage box 404 later.
[0028] Working principle: Before use, the operator can place the collection box 12 into the storage box 404, and then insert the snap-fit limiting plate 15 into the snap-fit groove 14 to limit the collection box 12. When the extrusion roller body 16 starts to operate, the nylon brush 306 will scrape off foreign objects such as asphalt particles from the surface of the extrusion roller body 16. The scraped particles will fall into the temporary storage box 401. With the cooperation of the inclined plate 10 and the guide block 11, the particles will flow smoothly to the surface of the sliding plate 402 and then into the storage box 404 through the sliding plate 402, and then fall into the collection box 12. Every once in a while, the operator can clean and recycle the particles inside the storage box 404. The collection mechanism 4 can effectively avoid the pollution of the working environment by foreign objects such as asphalt particles, and can also collect and reuse the particles, thus saving production costs to a certain extent.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
