Description

A device for enhancing tire base impregnation and compaction Technical Field

[0001] This application relates to the technical field of tire base processing, and in particular to a device for reinforcing tire base impregnation and compaction. Background Technology

[0002] The base material is the skeleton structure of asphalt waterproof membrane, much like the steel reinforcement in a building. It provides physical support for the membrane and determines key indicators such as its strength, flexibility, and tear resistance. A high-quality base material ensures that the membrane maintains good performance in different environments, effectively extending the service life of waterproof projects.

[0003] The production process of waterproof membrane requires two steps: pre-impregnation with oil and oil coating. Normally, when pre-impregnating the base material, the base material is completely immersed in oil (referring to asphalt) and then squeezed dry under pressure.

[0004] In actual factories, the distance between oil immersion tanks is limited, and the tire base is continuously transported during processing, resulting in a limited time that the tire base stays in the oil immersion tank. After one oil immersion and compaction, there is a defect of low filling rate of voids between fibers inside the tire base. Summary of the Invention

[0005] In order to improve the filling rate of the gaps between fibers inside the tire base during the oil impregnation process, this application provides a device for enhancing tire base impregnation and compaction.

[0006] The reinforcing tire base impregnation and compaction device provided in this application adopts the following technical solution:

[0007] An enhanced tire base impregnation and compaction device includes an oil impregnation tank, an unwinding roller mounted on the oil impregnation tank, and a first compaction component disposed within the oil impregnation tank. The first compaction component includes a first lower pressure roller and a first fixed roller. The first fixed roller is rotatably disposed relative to the oil impregnation tank, and the center line of its rotation axis coincides with the center line of the first fixed roller itself. The first lower pressure roller is slidably disposed on the oil impregnation tank and slides in a direction close to or away from the first fixed roller. A vibration component for tire base vibration is disposed above the oil impregnation tank. A guide roller is also disposed within the oil impregnation tank, and the guide roller is located on the side of the vibration component away from the first compaction component.

[0008] By adopting the above technical solution, the unwinding roller feeds the tire base into the immersion tank. After initial soaking, the tire base first passes through the first compaction component. Since the first compaction component is located inside the immersion tank, it compacts the tire base below the asphalt surface, which can fully compress the fiber gaps in the tire base and fill them with asphalt. Subsequently, the tire base passes through the vibration component. Under the action of the vibration component, the tire base vibrates, which helps the asphalt to better penetrate into the gaps between the fibers inside the tire base, improving the filling rate of the gaps by the asphalt. The guide roller guides the tire base. Since the guide roller is also located inside the immersion tank, it can guide the tire base to enter the immersion tank for a second soaking, improving the filling rate of the gaps between the fibers inside the tire base in the immersion process.

[0009] Optionally, the vibration assembly includes lifting rollers and a vibrating bar. There are two lifting rollers arranged in parallel. The two lifting rollers are spaced apart along the tire base conveying direction and are located on the same horizontal plane. The lifting rollers are rotated relative to the immersion tank. The vibrating bar is slidably arranged on the immersion tank and slides back and forth in the vertical direction. The vibrating bar is located between the two lifting rollers, and the bottom surface of the vibrating bar is used to intermittently contact the tire base.

[0010] By adopting the above technical solution, two parallel and spaced-apart lifting rollers can support and transport the tire base. The vibrating strip located between the two lifting rollers slides back and forth vertically and intermittently contacts the tire base, causing the tire base to vibrate. When the vibrating strip moves downward and contacts the tire base, it applies an impact force to the tire base, causing the internal fibers of the tire base to shake. Small air bubbles or areas that were not filled properly between the fibers are broken, allowing the asphalt to fill the gaps more fully. When the vibrating strip moves upward and leaves the tire base, the tire base recovers a certain shape under its own elasticity and the action of the lifting rollers. This process is repeated, further improving the filling rate of the gaps between the internal fibers of the tire base by the asphalt.

[0011] Optionally, a frame plate is fixed to the top of the oil immersion tank, a motor is fixed to the frame plate, an eccentric wheel is fixed to the output end of the motor, the eccentric wheel is vertically arranged, a connecting rod is arranged between the eccentric wheel and the vibrating bar, one end of the connecting rod is fixed to the non-center of the eccentric wheel, and the other end is bent downward and fixedly connected to the vibrating bar; a guide tube is fixed to the inner wall of the oil immersion tank, the open end of the guide tube is arranged in the vertical direction, and the vibrating bar is inserted into the guide tube and slidably arranged relative to the guide tube.

[0012] By adopting the above technical solution, the motor drives the eccentric wheel to rotate. The rotation of the eccentric wheel causes the connecting rod to move up and down, which in turn drives the vibrating strip to slide back and forth in the vertical direction along the guide tube. The guide tube guides and limits the vibrating strip, ensuring that the vibrating strip can move stably in the vertical direction. This makes the intermittent contact between the vibrating strip and the base more stable, ensuring the consistency and continuity of the vibration effect, providing a reliable power source for the effective vibration of the base, and ensuring that the asphalt can fully penetrate into the gaps between the fibers inside the base.

[0013] Optionally, a sleeve is fitted around the outer wall of the lifting roller, and a spring is fixed between the sleeve and the lifting roller.

[0014] By employing the above technical solution, the spring between the sleeve and the lifting roller allows the sleeve to generate a certain elastic displacement relative to the lifting roller. When the tire base passes the lifting roller, if the tire base thickness is uneven or there are local protrusions, the sleeve can adaptively adjust under the action of the spring, avoiding damage to the tire base due to rigid contact. At the same time, the elastic force of the spring ensures that the sleeve always maintains a certain pressure contact with the tire base. Combined with the vibration of the vibrating strip, this helps to further promote the penetration of asphalt into the gaps between the fibers inside the tire base, improving the asphalt filling rate.

[0015] Optionally, multiple springs are provided between each lifting roller and the corresponding sleeve, with adjacent springs on a single lifting roller spaced apart along the circumferential outer wall of the lifting roller.

[0016] By adopting the above technical solution, multiple springs are spaced apart along the circumferential outer wall of the lifting roller, ensuring that the sleeve maintains good contact with the tire base at different positions through the elastic force of the springs, thus guaranteeing the uniformity of pressure applied to the tire base. Regardless of where the tire base passes the lifting roller, it receives stable and uniform support and pressure. Combined with the vibration of the vibrating strip, this allows asphalt to penetrate more fully into the gaps between the fibers in all parts of the tire base, effectively improving the overall asphalt filling rate and oil impregnation quality of the tire base.

[0017] Optionally, a strip plate is fixed on the inner wall of the oil immersion tank, and an elongated hole for the tire base to pass through is opened on the strip plate, with the length of the elongated hole along the width of the tire base.

[0018] By adopting the above technical solution, the elongated holes on the strip provide a through channel for the tire base. During the oil immersion tank process, the tire base can be smoothly conveyed along the direction of the elongated holes, preventing displacement or wrinkling within the tank and ensuring the stability of the tire base during oil immersion and compaction. Simultaneously, the elongated holes allow the asphalt on the tire base surface to be scraped off.

[0019] Optionally, multiple elongated holes are provided, with adjacent elongated holes spaced apart, and the width of adjacent elongated holes gradually increases.

[0020] By adopting the above technical solution, the width of adjacent elongated holes gradually increases, which can adapt to the needs of tire base transportation of different thicknesses or different stages.

[0021] Optionally, the oil immersion tank is provided with a second compaction assembly for extruding the tire base, the second compaction assembly being located above the strip.

[0022] By adopting the above technical solution, the second compaction component is located above the strip plate, and can further compress the tire base after it passes through the strip plate. After vibration and oil impregnation by the vibration component, the gaps between the fibers inside the tire base have been partially filled. At this time, the second compaction component compresses the tire base, which can further expel excess air and asphalt inside the tire base, making the asphalt more tightly fill the gaps between the fibers. At the same time, it compacts the tire base, improves the density and strength of the tire base, and ultimately effectively improves the filling rate of the gaps between the fibers inside the tire base during the oil impregnation process.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The unwinding roller, the first compaction assembly, the vibrating assembly, the guide roller, and the second compaction assembly work together to form a complete tire base impregnation and compaction process. The first compaction assembly initially compresses the tire base below the asphalt surface, the vibrating assembly promotes asphalt penetration through vibration, the guide roller guides the tire base for secondary impregnation, and the second compaction assembly further compresses and removes excess material. This multi-stage collaborative operation significantly improves the filling rate of the gaps between fibers inside the tire base during the impregnation process, ensuring the tire base's waterproof performance and physical strength.

[0025] 2. The intermittent contact of the vibrating strips in the vibration assembly and the elastic cooperation design of the sleeve and spring on the lifting roller break up air bubbles and unfilled areas between fibers through vibration. On the other hand, the sleeve can adaptively adjust the contact pressure with the base material. The two work together to allow the asphalt to penetrate more fully into the fiber gaps of the base material and avoid damage to the base material. This improves the oil impregnation quality of the base material while ensuring the integrity of the base material.

[0026] 3. The elongated holes on the strips and their progressively wider design ensure smooth transport of the substrate in the oil immersion tank, preventing deviation and wrinkling, and guaranteeing stability during the oil immersion and compaction processes. The elongated holes of different widths can also adapt to the processing requirements of the substrate at different stages. Together with various compaction components, they can precisely control the degree of oil immersion and compaction effect of the substrate, effectively improving the filling rate of the gaps between the fibers inside the substrate and increasing the yield rate of waterproof membrane production.

Detailed Implementation

[0031] The present application will be further described in detail below with reference to Figures 1-3.

[0032] This application discloses a device for reinforcing tire base impregnation and compaction.

[0033] Referring to Figure 1, a reinforced tire base impregnation and compaction device includes an oil impregnation tank 1, which has a rectangular trough structure and is used to hold asphalt, providing working space for impregnating the tire base. Horizontal supports are welded to the top two sides of the oil impregnation tank 1. Unwinding rollers 11 are rotatably mounted on the supports via bearings. Unwinding rollers 11 can rotate freely around their own axis and are used to hold unprocessed tire base rolls. During production, the tire base is gradually unwound from the unwinding rollers 11 and enters the oil impregnation tank 1.

[0034] Referring to Figures 1 and 2, a first compaction assembly 2 is provided inside the oil immersion tank 1. The first compaction assembly 2 includes a first lower pressure roller 21 and a first fixed roller 22. The first fixed roller 22 is rotatably connected to the inner wall of the oil immersion tank 1 through rotating shafts at both ends. The center line of the rotating shafts coincides with the center line of the first fixed roller 22 itself, and the rotating shafts are installed in the pre-set shaft holes in the inner wall of the oil immersion tank 1 through bearings, so that the first fixed roller 22 can rotate freely relative to the oil immersion tank 1. A fixed plate 7 is fixed at the top of the oil immersion tank 1. A movable plate 71 and a screw 72 are provided between the fixed plate 7 and the first lower pressure roller 21. The first lower pressure roller 21 is rotatably mounted on the movable plate 71. The movable plate 71 is in close contact with the inner wall of the oil immersion tank 1, so that the movable plate 71 can only slide in the vertical direction and cannot rotate. The screw 72 is vertically arranged, passes through the fixed plate 7 and is rotatably connected to the movable plate 71. The screw 72 rotates relative to the movable plate 71 and is threadedly connected to the fixed plate 7.

[0035] Referring to Figures 2 and 3, a vibration assembly 3 for tire base vibration is provided above the oil immersion tank 1. The vibration assembly 3 includes two parallel lifting rollers 31 and a vibrating strip 32. The two lifting rollers 31 are spaced apart along the tire base conveying direction and located on the same horizontal plane. The two ends of the lifting rollers 31 are rotatably mounted on the side wall of the oil immersion tank 1 via bearings, and can rotate relative to the oil immersion tank 1. A sleeve 4 is sleeved around the outer wall of the lifting roller 31. Multiple springs 41 are fixed between the sleeve 4 and the lifting roller 31. Adjacent springs 41 on a single lifting roller 31 are spaced apart along the circumferential outer wall of the lifting roller 31. One end of the spring 41 is welded to the outer wall of the lifting roller 31, and the other end is welded to the inner wall of the sleeve 4, so that the sleeve 4 can generate elastic displacement relative to the lifting roller 31. The vibrating strip 32 is elongated. A guide tube 17 is fixed on the inner wall of the oil immersion tank 1. The open end of the guide tube 17 is arranged in the vertical direction. In this embodiment, only the lower end is open, that is, the opening faces downward. The vibrating strip 32 is inserted into the guide tube 17 and slides relative to the guide tube 17, thereby realizing the reciprocating sliding of the vibrating strip 32 in the vertical direction. The vibrating strip 32 is located between the two lifting rollers 31, and its bottom surface intermittently abuts against the tire base.

[0036] Referring to Figures 2 and 3, a frame plate 13 is fixed to the top of the oil immersion tank 1. A motor 14 is bolted to the frame plate 13. An eccentric wheel 15 is fixed to the output end of the motor 14. The eccentric wheel 15 is vertically arranged. A connecting rod 16 is provided between the eccentric wheel 15 and the vibrating bar 32. One end of the connecting rod 16 is welded to the non-center part of the eccentric wheel 15, and the other end is bent downward and welded to the vibrating bar 32. When the motor 14 is working, it drives the eccentric wheel 15 to rotate. The rotation of the eccentric wheel 15 causes the connecting rod 16 to move up and down, which in turn drives the vibrating bar 32 to slide back and forth in the vertical direction along the guide tube 17.

[0037] Referring to Figures 2 and 3, a guide roller 12 is also provided in the oil immersion tank 1. The guide roller 12 is rotatably connected to the inner wall of the oil immersion tank 1 through the rotating shafts at both ends. The guide roller 12 is located on the side of the vibration component 3 away from the first compaction component 2, and is used to guide the tire base to enter the oil immersion tank 1 for soaking for the second time.

[0038] Referring to Figures 2 and 3, a strip plate 5 is fixed on the inner wall of the oil immersion tank 1. The strip plate 5 has elongated holes 51 for the tire base to pass through. The length of the elongated holes 51 is along the width of the tire base, and multiple elongated holes 51 are provided, spaced apart, with the width of adjacent elongated holes 51 gradually increasing. A second compaction assembly 6 for compressing the tire base is provided on the oil immersion tank 1. The second compaction assembly 6 is located above the strip plate 5. The structure of the second compaction assembly 6 is similar to that of the first compaction assembly 2, including a second fixed roller 62 and a second lower pressure roller 61. A vertical plate 8 is fixed to the top of the oil immersion tank 1. The end of the second fixed roller 62 is rotatably connected to the corresponding vertical plate 8, meaning the second fixed roller 62 rotates relative to the vertical plate 8. The end of the second lower pressure roller 61 is slidably disposed on the vertical plate 8, sliding horizontally and also in a direction close to or away from the second fixed roller 62. Other driving methods can also be used, such as using a cylinder or hydraulic cylinder to drive the second lower roller 61 to slide left and right, so as to re-express the tire base after it passes the strip 5.

[0039] The implementation principle of the enhanced base impregnation and compaction device in this application embodiment is as follows: During the production process of waterproof membrane, the base roll is installed on the unwinding roller 11. The base roll is unwound from the unwinding roller 11 and enters the oil immersion tank 1 for initial impregnation. Subsequently, the base roll passes through the first compaction component 2 located below the asphalt surface inside the oil immersion tank 1, which initially fills the fiber gaps in the base roll with asphalt and squeezes out excess asphalt. Next, the base roll passes through the vibration component 3. Two lifting rollers 31 support and transport the base roll. The motor 14 drives the eccentric wheel 15 to rotate, and through the connecting rod 16, the vibrating strip 32 slides back and forth in the vertical direction and intermittently contacts the base roll, applying an impact force to the base roll to generate vibration, causing the fibers inside the base roll to shake, breaking small air bubbles and unfilled areas between the fibers, so that the asphalt is more fully filled into the gaps. At the same time, the sleeve 4 adaptively adjusts the contact pressure with the base roll under the action of the spring 41, further assisting the asphalt penetration. Afterward, the guide roller 12 guides the base roll to enter the oil immersion tank 1 for a second impregnation. When the tire base passes through the strip plate 5, the elongated hole 51 provides a through channel for the tire base, ensuring smooth transportation of the tire base. At the same time, it scrapes off excess asphalt from the surface of the tire base. Finally, the second compaction component 6 located above the strip plate 5 compresses the tire base again, expelling excess air and asphalt from inside the tire base, making the asphalt more tightly fill the gaps between the fibers, improving the density and strength of the tire base, thereby effectively improving the filling rate of the gaps between the fibers inside the tire base during the oil impregnation process.

[0040] The embodiments described in this specific implementation are 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.
