Description

Technical Field

[0001] The utility model relates to the technical field of automobile TPU lumbar support film processing, in particular to a traction device for automobile TPU lumbar support film processing. Background Art

[0002] Automotive TPU lumbar support film is a polyurethane film designed specifically to enhance the driver's lumbar comfort and support. It uses high-quality TPU particles as raw material and is carefully produced through advanced processes such as calendering, cast film or blown film. The thickness is usually between 0.05mm and 1.00mm. This film not only has excellent elasticity and softness, but can perfectly fit the human waist curve, providing the driver with the support and comfort required for long-term driving. It also has excellent wear resistance, folding resistance, and flame retardancy to ensure safety and durability during use. The production and processing of automotive TPU lumbar support film requires the use of a traction device. The traction device can prevent the film from deflecting, uneven stretching or breaking during processing, thereby ensuring the continuity of the production process and the consistency of the product.

[0003] The existing Chinese patent with announcement number CN219706072U discloses a coating traction device for PET sheet production, including a base, an operating table is fixedly provided on both sides of the top of the base, and a forward and reverse motor is fixedly installed on the top of the two operating tables. The output ends of the two forward and reverse motors extend to the interior of the two operating tables and are fixedly connected to the screw rods. The surfaces of the two screw rods are threaded with sleeves, and one side of the two sleeves is fixedly provided with a moving block. The ends of the two moving blocks away from the sleeves extend to the outside and are fixedly connected to the placement seats. A connecting slot is provided in the middle of the top of the two placement seats, and an arc-shaped placement groove is provided in the middle of the top of the base. A winding drum is provided inside the arc-shaped placement groove, and a connecting shaft is rotatably provided at both ends of the winding drum.

[0004] Although the above solution can replace the manual installation of the roll drum, which is more time-saving and labor-saving, the TPU lumbar support film is easily contaminated with dust during transportation during the processing process. The device lacks effective cleaning. If it is directly pulled, dust will adhere to the surface of the TPU lumbar support film, which will affect its appearance quality and performance. At the same time, the device lacks the tension adjustment of the automotive TPU lumbar support film, which causes the TPU lumbar support film to become wrinkled or uneven during transportation. Therefore, it does not meet the existing needs. In this regard, we propose a traction device for automotive TPU lumbar support film processing. Utility Model Content

[0014] Preferably, second guide rods are welded on both sides of one of the second transmission chambers, the second guide rods both pass through the second moving block, and the second guide rods both slide in conjunction with the second moving block.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model has a first transmission cavity provided on one side at the front and rear ends of the main body. A double-threaded transmission rod is rotatably provided inside one of the first transmission cavities. When the automotive TPU lumbar support film is pulled, it can be positioned between two dust-sticking rollers. By starting the first motor, the double-threaded transmission rod can be rotated, thereby driving the two first moving blocks to move the dust-sticking rollers toward each other, so that the dust-sticking rollers can contact the upper and lower ends of the automotive TPU lumbar support film. When the automotive TPU lumbar support film is pulled, the dust-sticking rollers can clean the upper and lower end surfaces of the automotive TPU lumbar support film, thereby effectively reducing dust absorption and ensuring the quality and performance of the automotive TPU lumbar support film after processing.

[0017] 2. The utility model has a second transmission cavity in the middle of the front and rear ends of the main body. Single-threaded transmission rods are rotatably arranged on both sides of one of the second transmission cavities. When the tension of the automotive TPU lumbar support film needs to be adjusted during transportation, the second motor can be started. After the second motor is started, the two single-threaded transmission rods will rotate synchronously. The single-threaded transmission rods will drive the second moving block to move in opposite directions, and the second moving block will drive the two movable guide rollers to move in opposite directions. If the automotive TPU lumbar support film is too loose, the tension can be increased by increasing the distance between the movable guide rollers. Conversely, if the automotive TPU lumbar support film is too tight, the tension can be reduced by reducing the distance between the movable guide rollers. This dynamic adjustment process can quickly respond to changes in the tension of the automotive TPU lumbar support film during transportation, ensuring that the automotive TPU lumbar support film always remains in the optimal tension state.

[0018] 3. The utility model provides a second rotating rod on both sides of one of the first transmission cavities, a first bevel gear is provided at one end of the second rotating rod, and a second bevel gear is provided on the other side of the second rotating rod. When the second motor is started, the second rotating rod can be rotated under the meshing transmission of the first bevel gear, and the second rotating rod can rotate the third rotating rod through the first bevel gear, thereby driving the two single-threaded rods to rotate synchronously. The characteristics of synchronous transmission make the movement of the automotive TPU lumbar support film more stable during the traction process, reduce material wear and energy loss caused by vibration or irregular movement, and improve the operating efficiency of the production line.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-4 The utility model provides a technical solution: a traction device for processing automotive TPU lumbar support film, comprising a main body 1, a fixed guide roller 20 is rotatably provided on one side of the interior of the main body 1, a third motor 21 is provided on one side of the front end of the main body 1, and the output end of the third motor 21 is connected to the fixed guide roller 20 via a coupling;

[0026] It also includes a first transmission chamber 2, which is opened on one side of the front and rear ends of the main body 1. A double-threaded transmission rod 4 is rotatably provided inside one of the first transmission chambers 2. First moving blocks 5 are provided on the upper and lower sides of the first transmission chamber 2. The double-threaded transmission rod 4 passes through the first moving block 5 and is threadedly connected to the first moving block 5. Two sticky rollers 6 are provided on the other side of the main body 1, and the front and rear ends of the sticky rollers 6 are connected to the first moving block 5 through a rotating shaft.

[0027] It also includes a second transmission chamber 8, which is opened at a position between the front and rear ends of the main body 1, and a single-threaded transmission rod 16 is rotatably provided at the upper ends of both sides of the interior of one of the second transmission chambers 8, and a second moving block 17 is provided on the upper sides of both sides of the interior of the second transmission chamber 8. The single-threaded transmission rod 16 passes through the second moving block 17, and the single-threaded transmission rod 16 slides with the second moving block 17. Two movable guide rollers 19 are provided at the middle position inside the main body 1, and the front and rear ends of the movable guide roller 19 are connected to the second moving block 17 through a rotating shaft.

[0028] During use, the automotive TPU lumbar support film passes through the main body 1, and the fixed guide roller 20 is driven by the third motor 21 to rotate to realize the traction and transportation of the automotive TPU lumbar support film. During the process, the automotive TPU lumbar support film passes through the double-threaded transmission rod 4 in the first transmission cavity 2, and the first motor 3 drives the first moving blocks 5 at both ends to move vertically along the first guide rod 7, driving the dust-sticking roller 6 to fit the film surface to remove dust. Then the automotive TPU lumbar support film passes through the channel formed by the dynamic guide roller 19, and the second motor 9 drives the second moving block 17 to move vertically on the second guide rod 18 through the transmission structure composed of the first rotating rod 10 and the first bevel gear 11 group, the second rotating rod 13, the second bevel gear 14, the third rotating rod 15 and the single-threaded transmission rod 16, and adjusts the height difference of the dynamic guide roller 19, thereby controlling the tension of the film to ensure that it is in the best state for subsequent processing.

[0029] See also Figure 2 A first motor 3 is provided below the double-threaded transmission rod 4, and the output end of the first motor 3 is connected to the double-threaded transmission rod 4 through a coupling. The first motor 3 provides power for the vertical movement of the dust-sticking roller 6;

[0030] See also Figure 4 A second motor 9 is provided at the front side of the lower end of one of the second transmission chambers 8. A first rotating rod 10 is provided at the output end of the second motor 9 through a coupling, and the first rotating rod 10 is rotatably connected to the second transmission chamber 8. The second motor 9 provides power for adjusting the tension;

[0031] See also Figure 4, a second rotating rod 13 is rotatably provided on both sides of the lower end of one of the second transmission chambers 8, and a bearing 12 is provided at the middle position of the outer wall of the second rotating rod 13.

A first bevel gear 11 is provided on the rear side of the outer wall of the first rotating rod 10 and one end of the second rotating rod 13, and the first bevel gears 11 are meshed and connected. The application of the bearing 12 reduces the friction resistance when the second rotating rod 13 rotates, and improves the stability and smoothness of the rotation. The meshing transmission of the first bevel gear 11 realizes the smooth transmission of power and the change of direction, which provides strong support for subsequent transmission;

[0032] See also Figure 2 and Figure 4 , the lower end of the single-thread transmission rod 16 is provided with a third rotating rod 15, and the third rotating rod 15 is rotatably connected to the second transmission cavity 8, and the lower side of the outer wall of the third rotating rod 15 and one side of the outer wall of the second rotating rod 13 are provided with a second bevel gear 14, and the second bevel gears 14 are meshed and connected. Through the re-engagement transmission of the second bevel gear 14, the power is transmitted from the second rotating rod 13 to the third rotating rod 15, and then the single-thread transmission rod 16 is driven to rotate, thereby realizing the extension of the power transmission path and the further adjustment of the direction, and meeting the complex requirements of the height adjustment of the dynamic guide roller 19;

[0033] See also Figure 3 A first guide rod 7 is welded inside one of the first transmission chambers 2. The first guide rod 7 passes through the first moving block 5 and is slidably engaged with the first moving block 5. The first guide rod 7 provides a stable guide and limit function for the vertical movement of the first moving block 5, preventing deviation and shaking during movement, and ensuring that the sticky roller 6 can accurately and stably adhere to the surface of the car's TPU lumbar support film for cleaning;

[0034] See also Figure 3 Second guide rods 18 are welded on both sides of the inside of one of the second transmission chambers 8. The second guide rods 18 all pass through the second moving block 17, and the second guide rods 18 all slide with the second moving block 17. The second guide rods 18 provide reliable guidance and support for the vertical movement of the second moving block 17, ensuring that the dynamic guide roller 19 can move smoothly and accurately when adjusting the height, thereby realizing precise control of the tension of the automobile TPU lumbar support film.

[0035] Working principle: When in use, the automobile TPU lumbar support film is passed through the main body 1, and the fixed guide roller 20 is rotated by starting the third motor 21 to pull and transport the automobile TPU lumbar support film, so that the automobile TPU lumbar support film will pass between the two sticky rollers 6, and the first motor 3 is started. The first motor 3 will rotate the double-threaded transmission rod 4 through the coupling, and the double-threaded transmission rod 4 will drive the two first moving blocks 5 to rotate synchronously. Since one end of the first moving block 5 is slidably matched with the first guide rod 7, the first moving block 5 will be axially limited, and the rotation of the two first moving blocks 5 will be converted into opposite or opposite vertical movement. When the first moving block 5 moves, it will drive the sticky roller 6 to move synchronously, which can adapt to automobile TPU lumbar support films of different thicknesses, so that the sticky roller 6 fits the upper and lower end surfaces of the automobile TPU lumbar support film. When the automobile TPU lumbar support film is pulled, it will synchronously drive the sticky roller 6 to rotate. The sticky roller 6 can clean the dust on the ground above and below the automobile TPU lumbar support film to avoid affecting the quality and performance after processing, and the automobile TPU lumbar support film is passed through the two moving guide rods. The second motor 9 is started when the tension needs to be adjusted after the upper and lower ends of the roller 19 are passed. The second motor 9 will rotate the first rotating rod 10 through the coupling. The first rotating rod 10 will drive one of the first bevel gears 11 to rotate. The first bevel gear 11 is meshed with the remaining two first bevel gears 11 for transmission, so it will drive the second rotating rod 13 to rotate synchronously. The bearing 12 ensures the smooth rotation of the second rotating rod 13. The second rotating rod 13 will rotate synchronously through the meshing transmission between the second bevel gears 14. The three-rotating rod 15 will drive the single-threaded transmission rod 16 to rotate synchronously, and the single-threaded transmission rod 16 will drive the second movable block 17 to rotate synchronously. The second movable block 17 is axially limited by the second guide rod 18, and its rotation will be converted into vertical movement up and down. The two second movable blocks 17 move in opposite directions and drive the movable guide roller 19 to move synchronously. By controlling the height difference between the two movable guide rollers 19, the tension of the automotive TPU lumbar support film can be controlled, ensuring that the automotive TPU lumbar support film is always maintained in the optimal tension state.
