Description

Technical Field

[0001] This invention relates to a tire cord impregnation adjustment system, and pertains to the field of tire cord impregnation technology. Background Technology

[0002] During the production process, tire cord fabric undergoes a rubber impregnation process to enhance its adhesion to rubber. During impregnation, the tire cord fabric continuously passes through the impregnation tank. Currently, the drive rollers in the impregnation tank are fixed. In actual production, the raw fabric enters the impregnation tank, allowing the rubber solution to penetrate and adhere to its surface. As production progresses, the amount of rubber solution in the tank decreases, and the time the raw fabric spends in the solution becomes shorter. This results in the rubber solution not penetrating the gaps in the fabric effectively, further affecting the adhesion of the rubber solution to the fabric surface. This not only affects the final quality of the tire cord fabric but also subsequent tension control and the final roll quality.

[0003] Although the scraper blades can be adjusted during subsequent processes, varying adhesive thickness on the fabric can prevent them from achieving optimal results. Furthermore, scraping thicker adhesive layers can cause fluctuations in the fabric's running speed due to resistance, thus affecting the overall operation of the production equipment and exacerbating negative impacts on production quality. Additionally, the fixed adhesive tank for the drive rollers does not allow for convenient adjustment of the original fabric's impregnation time to suit different product requirements and thus adjust the adhesive thickness. Summary of the Invention

[0004] The purpose of this invention is to design a curtain fabric impregnation adjustment system that allows for real-time adjustment of the impregnation position of the curtain fabric.

[0005] The present invention includes a tank body, in which dip rollers are disposed, including a first dip roller and a second dip roller arranged side by side. A frame above the tank body is provided with a front-to-back position adjustment mechanism for the first dip roller and a vertical position adjustment mechanism for the second dip roller. A first bracket connected to the shaft seat of the first dip roller is connected to the front-to-back position adjustment mechanism, and a second bracket connected to the shaft seat of the second dip roller is connected to the vertical position adjustment mechanism. A lateral distance sensor between the first bracket and the frame is disposed on the first bracket, and a vertical distance sensor between the second bracket and the frame is disposed on the second bracket. A liquid level sensor is disposed on the tank body or the frame. A speed adjustment mechanism is disposed at at least one end of the tank body. The liquid level sensor, the lateral distance sensor, the vertical distance sensor, and the speed adjustment mechanism are connected to a control mechanism.

[0006] Furthermore, the speed adjustment mechanism includes a front speed adjustment roller, a middle speed adjustment roller, and a rear speed adjustment roller arranged sequentially behind the second dip roller and mounted on a speed adjustment bracket. The shafts of the front and rear speed adjustment rollers are rotatably mounted on the speed adjustment bracket. A speed adjustment hydraulic cylinder with an upward piston rod is provided on the speed adjustment bracket between the two rollers. The two ends of the middle speed adjustment roller are provided on a shaft connected to the piston rod of the speed adjustment hydraulic cylinder. The speed adjustment hydraulic cylinder is connected to the control mechanism.

[0007] Furthermore, the front and rear position adjustment mechanism includes a mounting plate and a transverse moving plate fixed on the frame. A transverse moving motor is provided on the mounting plate, and a gear is provided on the shaft of the transverse moving motor. A rack that meshes with the gear is provided on the transverse moving plate. Traveling wheels are provided at both ends of the transverse moving plate, and the traveling wheels are located on the travel guide rails on the frame. The first bracket is fixedly connected to the transverse moving plate.

[0008] Furthermore, the vertical position adjustment mechanism includes a hydraulic cylinder whose cylinder body is fixed on the mounting plate, the piston rod of the hydraulic cylinder being connected to the longitudinal moving plate, and the second bracket being fixedly connected to the longitudinal moving plate.

[0009] Furthermore, the vertical distance sensor and its sensing mechanism are respectively mounted on the mounting plate and the longitudinal moving plate; the lateral distance sensor and its sensing mechanism are respectively mounted on the frame and the lateral moving plate.

[0010] Furthermore, a horizontal guide roller is installed at the rear of the pool body, and an upward-facing scraper is installed after the horizontal guide roller. A guide plate leading to the pool body is installed below the scraper.

[0011] This invention includes a front-to-back position adjustment mechanism and a vertical position adjustment mechanism, which can adjust the impregnation position of the cord fabric according to the liquid level of the adhesive in the tank, so that the cord fabric can adapt to different liquid levels during impregnation. An adhesive level sensor is installed above the tank to monitor the liquid level in the tank in real time. The position of the impregnation roller is adjusted sequentially by a horizontal distance sensor and a vertical distance sensor, so that the cord fabric can have sufficient impregnation time as the adhesive level gradually decreases, thereby improving the uniformity of the cord fabric impregnation.

In this embodiment, five traveling wheels 7 are provided, and each traveling wheel 7 is evenly distributed along the front and back of the transverse moving plate 6 to ensure the flatness of the transverse moving plate 6. A travel guide rail 8 is provided below the traveling wheel 7. The travel guide rail 8 is fixedly installed in the through groove of the transverse moving plate 6 and cooperates with the traveling wheel 7. In use, the traveling wheel 7 can move back and forth along the travel guide rail 8. A transverse moving motor 9 is fixedly installed at the upper front end of the mounting plate 5. The rotating shaft of the transverse moving motor 9 passes downward through the mounting plate 5 and is equipped with a gear 10. A rack 11 is provided on the left side of the gear 10 and meshes with it. The rack 11 is arranged in the front and back direction and is fixedly installed at the upper end of the transverse moving plate 6. In use, the transverse moving motor 9 is started, and the transverse moving plate 6 can be controlled to move back and forth through the meshing of the gear 10 and the rack 11. In this embodiment, the upper end of the first bracket 4 is fixedly connected to the lower end face of the transverse moving plate 6, which enables the first dipped roller 3 to move back and forth with the transverse moving plate 6.

[0015] A second dip roller 12 is arranged parallel to the first dip roller 3 on its rear side. Second brackets 13 are fixedly connected to the bearing seats on both sides of the second dip roller 12. A vertical adjustment mechanism is connected to the upper end of each second bracket 13. The vertical adjustment mechanism includes a longitudinal moving plate 14 located below the mounting plate 5. Longitudinal grooves 15, corresponding to the dimensions of the longitudinal moving plate 14, are formed on the left and right sides of the frame 2. The left and right ends of the longitudinal moving plate 14 extend into and are slidably connected to the longitudinal grooves 15. A limiting block 16 is provided at the lower part of the longitudinal groove 15. The limiting block 16 is fixedly connected to the frame 2 and limits the downward movement of the longitudinal moving plate 14, preventing it from detaching from the longitudinal groove 15.

[0017] A guide roller group 18 is provided at the front of the pool body 1. The guide roller group 18 consists of two guide rollers arranged side by side. The bearing portion of each guide roller is fixedly installed on the frame 2. The curtain fabric passes through the two guide rollers and enters the pool body 1, which supports and guides the curtain fabric. A horizontal guide roller 19 is provided at the rear of the pool body 1. The bearing portion of the horizontal guide roller 19 is fixedly installed on the frame 2. The glue-impregnated curtain fabric passes over the horizontal guide roller 19. Its outer circumference is adjacent to the second glue-impregnated roller 12, which enables the glue-impregnated curtain fabric to be conveyed vertically upward so that excess glue flows down into the pool body. A scraper 20 is provided after the horizontal guide roller 19. The scraper 20 is inclined upward and its upper end contacts the curtain fabric, which can further remove excess adhesive from the curtain fabric. A guide plate 21 is provided below the scraper 20.

[0019] A speed adjustment mechanism is provided at the rear end of the pool body 1. The speed adjustment mechanism includes a speed adjustment bracket 22 fixed on the ground. A front speed adjustment roller 23, a middle speed adjustment roller 26 and a rear speed adjustment roller 24 are arranged sequentially on the upper part of the speed adjustment bracket 22. The shafts of the front speed adjustment roller 23 and the rear speed adjustment roller 24 are rotatably mounted on the speed adjustment bracket. A speed adjustment hydraulic cylinder 25 is provided on the speed adjustment bracket 22 between the front speed adjustment roller 23 and the rear speed adjustment roller 24. In this embodiment, there are two speed adjustment hydraulic cylinders 25. The cylinder body of each speed adjustment hydraulic cylinder 25 is fixedly connected to the speed adjustment bracket 22, and its piston rod extends upward. The two ends of the middle speed adjustment roller 26 are arranged on the shaft connected to the piston rod of the speed adjustment hydraulic cylinder 25, and the middle speed adjustment roller 26 is rotatably connected to the piston rod of the speed adjustment hydraulic cylinder 25. When in use, starting the speed adjustment hydraulic cylinder 25 can make the middle speed adjustment roller 26 move up and down. A pressure sensor 30 is installed in the piston rod of the rear speed-regulating hydraulic cylinder 25. The sensing end of the pressure sensor 30 faces upward and can detect the downward pressure applied by the intermediate speed-regulating roller 26, thereby determining the tension of the curtain fabric.

[0020] In this embodiment, each dip roller, guide roller, and speed regulating roller is a driven roller, which can rotate with the conveying of the cord fabric, thereby reducing the friction on the cord fabric.

[0021] In this embodiment, a liquid level sensor 27 is provided at the upper front end of the tank body 1, with the sensing connector of the liquid level sensor 27 facing downwards, for detecting the liquid level height of the liquid in the tank body 1; a lateral distance sensor 28 is provided on the front side of the lateral moving plate 6, and the lateral distance sensor 28 is fixedly installed on the frame 2, with its sensing connector facing backwards; a sensing mechanism for triggering the lateral distance sensor 28 is fixedly installed on the front end face of the lateral moving plate, so that the front and rear positions of the first dip roller 3 can be determined by detecting the lateral moving plate 6; a vertical distance sensor 29 is provided above the longitudinal moving plate 14, and the vertical distance sensor 29 is fixedly installed on the lower end face of the mounting plate 5, with its sensing connector facing downwards; a sensing mechanism for triggering the vertical distance sensor 29 is fixedly installed on the upper end face of the longitudinal moving plate, so that the vertical position of the second dip roller 12 can be determined by detecting the longitudinal moving plate 14.

[0022] In this embodiment, the adhesive level sensor 27, the lateral distance sensor 28, the vertical distance sensor 29, and the pressure sensor 30 in the speed regulation mechanism are all connected to the control mechanism. The control mechanism can receive signals from each sensor and execute corresponding actions.

[0023] In this embodiment, the cord fabric first enters the tank 1 through the guide roller group 18, passes through the first dip roller 3 and the second dip roller 12, and is then guided to the speed adjustment mechanism by the horizontal guide roller 19 for subsequent processes. During the dip process, the amount of adhesive in the tank 1 gradually decreases. The adhesive level sensor 27 detects a drop in the adhesive level in the tank 1 and sends a signal. The control mechanism then controls the transverse motor 9 to start, causing the first dip roller 3 to move forward, increasing the travel distance of the cord fabric in the adhesive. During the movement, the position of the first dip roller 3 is detected by the transverse distance sensor 28, and it stops after moving forward a certain distance. In this embodiment, the drop in the adhesive level detected by the adhesive level sensor 27 corresponds to the forward movement distance of the first dip roller 3 detected by the transverse distance sensor 28, ensuring that the cord fabric has sufficient dip travel distance in the adhesive. As the first impregnation roller 3 moves forward, the tension of the cord fabric increases. After the pressure sensor 30 detects the increase in cord fabric tension, it sends a signal, and the control system controls the intermediate speed regulating roller 26 to move downward. When the tension of the cord fabric reaches the set range, the intermediate speed regulating roller stops moving downward.

[0024] The above steps are repeated as the adhesive level decreases. When the first dip roller 3 moves to the front limit, the control mechanism activates the hydraulic cylinder 17 after the adhesive level sensor 27 sends a signal, controlling the second dip roller 12 to descend. During descent, the position of the second dip roller 12 is detected by the vertical distance sensor 29, and it stops after descending a certain distance. In this embodiment, the height of the liquid level drop detected by the adhesive level sensor 27 corresponds to the distance of descent of the second dip roller 12 detected by the vertical distance sensor 29. As mentioned above, during the descent of the second dip roller 12, the intermediate speed-regulating roller 26 will descend with the increase of tension. The above steps are repeated as the adhesive level decreases. When the second dip roller 12 moves to the lower limit, the vertical position sensor 29 sends a signal, and the control mechanism opens the inlet pipe of the tank 1 to replenish the adhesive. During the replenishment process, the second dip roller 12 and the first dip roller 3 reset sequentially. During the reset process, the intermediate speed-regulating roller 26 moves upward as the tension of the curtain fabric decreases, so that the tension of the curtain fabric can meet the set range.
