A tire inner liner extending and pressing device

Abstract

This utility model belongs to the field of tire inner liner processing technology, specifically a tire inner liner calendering device. It comprises a first positive and negative threaded screw, a pressure roller, a moving screw, and a movable wheel. A first motor drives the first positive and negative threaded screw to rotate, which in turn drives a lifting block and the pressure roller to move closer together to a suitable distance. Simultaneously, the rotation of the first positive and negative threaded screw drives a worm gear, which in turn drives a worm wheel and the moving screw to rotate. This causes the moving screw to move a moving plate and the movable wheel, allowing the movable wheel to move when the two pulleys on both sides move closer together to support the belt. Through the transmission between the pulleys and the belt, a gear and a pressure roller rotate in the same direction. The meshing of the gears causes another gear fixedly connected to the pressure roller to rotate in the opposite direction. The two pressure rollers push the material to move and calender it, achieving adjustable pressure roller spacing and improving the device's practicality.

Description

Technical Field

[0001] This utility model relates to the field of tire inner liner processing technology, specifically a tire inner liner pressing device. Background Technology

[0002] Calendering is an important step in the manufacturing of tire inner liner. It involves pressing rubber material through the rollers of a calendering device to form the required thickness and shape, thereby shaping the inner liner.

[0003] Existing tire inner liner calendering devices often have fixed roller spacing, making it difficult to adjust the required inner liner thickness and reducing the practicality of the calendering device. Therefore, a tire inner liner calendering device is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A tire inner liner pressing device of this utility model includes a frame, a conveying roller assembly arranged inside the frame, a first motor fixedly connected to the outside of the frame, a first threaded screw fixedly connected to the output end of the first motor, a lifting block threadedly connected to the outside of the first threaded screw, the lifting block being slidably connected to the frame, a pressure roller rotatably connected to the inside of the lifting block, a gear rotatably connected to the outside of one of the lifting blocks, the gears meshing with each other, a gear fixedly connected to the pressure roller, and pulleys fixedly connected to one end of another pressure roller and one end of another gear, with a belt rotatably connected to the outside of the pulleys. A worm gear is fixedly connected to the outside of one of the first threaded screws, a worm wheel meshing with the outside of the worm gear, a movable screw fixedly connected to the inside of the worm wheel, the movable screw rotatably connected to the frame, a movable plate threadedly connected to the outside of the movable screw, and a movable wheel rotatably connected to the outside of the movable plate. The movable wheel and belt work together, and the movable wheel is slidably connected to the frame. A second motor is fixedly connected to the outside of one of the lifting blocks, and a pressure roller is fixedly connected to the output end of the second motor. This step involves setting up a first positive and negative threaded screw, a pressure roller, a moving screw, and a movable wheel. The first motor drives the first positive and negative threaded screw, which in turn drives the lifting block and the pressure roller to move closer together to a suitable distance. Simultaneously, the rotation of the first positive and negative threaded screw drives the worm gear to rotate, which in turn drives the worm wheel and the moving screw to rotate. This causes the moving screw to move the moving plate and the movable wheel, allowing the movable wheel to move when the two pulleys on both sides move closer together to support the belt. Then, through the transmission between the pulleys and the belt, a gear and a pressure roller rotate in the same direction. Through the meshing of the gears, another gear fixedly connected to the pressure roller rotates in the opposite direction. The two pressure rollers push the material to move and perform calendering processing, making the pressure roller spacing adjustable and improving the practicality of the device.

[0006] Preferably, a dust collection groove is provided on the surface of the frame, and a vacuum cleaner is fixedly connected to the outside of the frame. The vacuum cleaner and the pressure roller are used in conjunction. This step, by setting up the dust collection groove and the vacuum cleaner, allows the pressure roller to be moved to the dust collection groove and rotated after the device is used. Then, the vacuum cleaner removes the excess waste on the surface of the pressure roller, so as to keep the pressure roller clean and improve the practicality of the device.

[0007] Preferably, a scraper is fixedly connected to the inner side of the dust collection groove, and the scraper is used in conjunction with the pressure roller. This step, by setting the scraper, ensures that when the pressure roller approaches the dust collection groove, it will stick to the scraper. Thus, when the pressure roller rotates, the scraper scrapes off the excess debris adhering to its surface through one end, thereby making it easier for the vacuum cleaner to absorb and collect the debris, and improving the convenience of cleaning the device.

[0008] Preferably, a limiting rod is slidably connected to the outer side of the frame, and the limiting rod is fixedly connected to the moving plate. This step, by setting the limiting rod, restricts the moving plate by the frame when it moves, thereby further restricting the moving trajectory of the moving plate, making it less prone to shaking during movement and improving the stability of the device.

[0009] Preferably, a second positive and negative threaded screw is rotatably connected to the inner side of the frame, and a limiting plate is threadedly connected to the outer side of the second positive and negative threaded screw. The limiting plate and the frame are slidably connected. This step, by setting the second positive and negative threaded screw and the limiting plate, allows the limiting plates to move closer to each other when the material is fed between the pressure rollers, thereby restricting and guiding the material being rolled, making its discharge trajectory more stable, and improving the stability of the device.

[0010] Preferably, an extension strip is fixedly connected to the outer side of the limiting plate, and the extension strip is slidably connected to the frame. This step, by setting the extension strip, allows the extension strip to simultaneously restrict the opening on one side of the frame when the limiting plates approach each other to restrict the calendered material. This further restricts the material entering between the pressure rollers, aligning it with the calendered discharge position and improving the stability of the device.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a first positive and negative threaded screw, a pressure roller, a movable screw, and a movable wheel, uses a first motor to drive the first positive and negative threaded screw, which in turn drives the lifting block and the pressure roller to move closer together to a suitable distance. Simultaneously, the rotation of the first positive and negative threaded screw drives the worm gear to rotate, which in turn drives the worm wheel and the movable screw to rotate. This causes the movable screw to move the movable plate and the movable wheel, allowing the movable wheel to move when the two pulleys on both sides move closer together to support the belt. Then, through the transmission between the pulleys and the belt, one gear and a pressure roller rotate in the same direction, and through the meshing of the gears, another gear fixedly connected to the pressure roller rotates in the opposite direction. The two pressure rollers push the material to move and perform calendering processing, achieving adjustable pressure roller spacing and improving the practicality of the device.

[0013] 2. By setting up a dust collection trough and a vacuum cleaner, this utility model allows the pressure roller to be moved to the dust collection trough and rotated after the device is used. Then, the vacuum cleaner removes the excess debris adhering to the surface of the pressure roller, thus keeping the pressure roller clean and improving the practicality of the device.

[0021] 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.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5As shown, a tire inner liner pressing device includes a frame 1, with a conveyor roller assembly 2 lined inside the frame 1. A first motor 3 is fixedly connected to the outside of the frame 1, and a first threaded screw 4 is fixedly connected to the output end of the first motor 3. A lifting block 5 is threadedly connected to the outside of the first threaded screw 4. The lifting block 5 is slidably connected to the frame 1. A pressure roller 6 is rotatably connected to the inside of the lifting block 5. A gear 7 is rotatably connected to the outside of one of the lifting blocks 5, and the gears 7 mesh with each other. One gear 7 is fixedly connected to the pressure roller 6. One end of the other pressure roller 6 and one end of the other gear 7 are both fixedly connected to a pulley 8. A belt 9 is rotatably connected to the outer side of the pulley 8. A worm 10 is fixedly connected to the outer side of the first positive and negative thread screw 4 on one side. A worm wheel 11 meshes with the outer side of the worm 10. A movable screw 12 is fixedly connected to the inner side of the worm wheel 11. The movable screw 12 is rotatably connected to the frame 1. A movable plate 13 is threadedly connected to the outer side of the movable screw 12. A movable wheel 14 is rotatably connected to the outer side of the movable plate 13. The movable wheel 14 works in conjunction with the belt 9. The movable wheel 14 and frame 1 are slidably connected. A second motor 15 is fixedly connected to the outside of one of the lifting blocks 5, and the output end of one of the pressure rollers 6 and the second motor 15 is fixedly connected. This step involves setting up a first positive and negative thread screw 4, a pressure roller 6, a movable screw 12, and a movable wheel 14. The first motor 3 drives the first positive and negative thread screw 4 to rotate, which in turn drives the lifting block 5 and the pressure roller 6 to move closer together to a suitable distance. At the same time, the rotation of the first positive and negative thread screw 4 drives the worm gear 10 to rotate, which in turn drives the worm wheel 11 and the movable screw. Rotating rod 12 causes the movable screw 12 to drive the movable plate 13 and movable wheel 14 to move, allowing the movable wheel 14 to move when the two pulleys 8 on both sides are close to each other, thus supporting the belt 9. Then, through the transmission between the pulleys 8 and the belt 9, a gear 7 and a pressure roller 6 rotate in the same direction. Through the meshing of the gears 7, another gear 7 fixedly connected to the pressure roller 6 rotates in the opposite direction. The two pressure rollers 6 on both sides push the material to move and perform calendering treatment, making the spacing between the pressure rollers 6 adjustable and improving the practicality of the device.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, a dust collection groove 101 is provided on the surface of the frame 1, and a vacuum cleaner 16 is fixedly connected to the outside of the frame 1. The vacuum cleaner 16 and the pressure roller 6 are used in conjunction. By setting up the dust collection groove 101 and the vacuum cleaner 16, after the device is used, the pressure roller 6 is moved to the dust collection groove 101 and rotated, and then the vacuum cleaner 16 removes the excess debris adhering to the surface of the pressure roller 6, so as to keep the pressure roller 6 clean and improve the practicality of the device.

[0025] Furthermore, such as Figure 1 and Figure 3As shown, a scraper 17 is fixedly connected to the inner side of the dust collection groove 101. The scraper 17 works in conjunction with the pressure roller 6. By setting the scraper 17, when the pressure roller 6 approaches the dust collection groove 101, it will stick to the scraper 17. Thus, when the pressure roller 6 rotates, the scraper 17 scrapes off the excess debris on its surface, making it easier for the vacuum cleaner 16 to absorb and collect the debris, thus improving the convenience of cleaning the device.

[0026] Furthermore, such as Figure 2 and Figure 4 As shown, a limiting rod 18 is slidably connected to the outside of the frame 1, and the limiting rod 18 is fixedly connected to the moving plate 13. This step, by setting the limiting rod 18, restricts the moving plate 13 by the frame 1 when it moves, and further restricts the moving trajectory of the moving plate 13 by the limiting rod 18, making it less prone to shaking when it moves and improving the stability of the device.

[0027] Furthermore, such as Figure 1 , Figure 2 and Figure 5 As shown, a second threaded screw 19 is rotatably connected to the inner side of the frame 1, and a limiting plate 20 is threadedly connected to the outer side of the second threaded screw 19. The limiting plate 20 and the frame 1 are slidably connected. This step, by setting the second threaded screw 19 and the limiting plate 20, allows the limiting plates 20 to move closer to each other when the material is fed between the pressure rollers 6, thereby restricting and guiding the material being rolled, making its discharge trajectory more stable, and improving the stability of the device.

[0028] Furthermore, such as Figure 1 and Figure 5 As shown, an extension strip 21 is fixedly connected to the outer side of the limiting plate 20, and the extension strip 21 is slidably connected to the frame 1. This step, by setting the extension strip 21, allows the extension strip 21 to simultaneously restrict the opening on one side of the frame 1 when the limiting plates 20 approach each other to restrict the calendered material. This further restricts the material entering between the pressure rollers 6, so that it can be aligned with the calendered discharge position, thereby improving the stability of the device.

[0029] The working principle is as follows: The first motor 3 drives the first positive and negative threaded screw 4 to rotate, which in turn drives the lifting block 5 and the pressure roller 6 to move closer together to a suitable distance. At the same time, the rotation of the first positive and negative threaded screw 4 on one side drives the worm gear 10 to rotate, which in turn drives the worm wheel 11 and the moving screw 12 to rotate. This causes the moving screw 12 to drive the moving plate 13 and the movable wheel 14 to move, allowing the movable wheel 14 to move when the two pulleys 8 on both sides are close together. This helps to expand and support the belt 9, preventing the belt 9 from becoming loose when the pulleys 8 are close together. Then, the second motor 15 drives the pressure roller 6 on one side to rotate, which in turn drives the pulley 8 on the other side to rotate. Through the transmission between the pulley 8 and the belt 9, the pulley 8 on the other side drives a gear 7 to rotate, causing the gear 7 and the pressure roller 6 to rotate in the same direction. Through the meshing of the gears 7, the other gear 7 drives the other pressure roller 6 to rotate in the opposite direction. The two pressure rollers 6 on both sides push the material to move and perform calendering.
