Description

Technical Field

[0001] This utility model relates to the technical field of pinch roll devices, and in particular to a dual-station quick-switching pinch roll device for an aluminum plate rolling line. Background Technology

[0002] An aluminum sheet rolling line is a production line used to produce aluminum sheets. It processes aluminum ingots or billets into aluminum sheets of different thicknesses and specifications through a series of rolling processes. An aluminum sheet rolling line typically includes several main pieces of equipment and process steps, covering the entire production process from raw material preparation to finished aluminum sheets.

[0003] Patent application CN220862392U discloses a pinch roller mechanism for a strip steel coiler, relating to the technical field of strip steel coiling equipment. It includes two vertical plates. A first bearing is fixedly embedded on the right side of one of the vertical plates, and a second bearing is fixedly embedded on the right side of the other vertical plate. Two positioning plates are arranged between the two vertical plates, each with a threaded hole on its right side. A motor is located on the right side of one of the vertical plates, and the output end of the motor is fixedly connected to a positive and negative threaded rod. This pinch roller mechanism for the strip steel coiler, through the cooperation of the motor, threaded hole, and positive and negative threaded rod, allows the motor to drive the positive and negative threaded rod to rotate within the threaded hole. The two positioning plates can then move closer or further apart depending on the width of the strip steel, making it suitable for strip steel of different widths and providing a limiting and correcting effect for the conveyed strip steel.

[0004] However, the pinch roll mechanism does not have a quick switching function. In modern aluminum plate rolling production, it is often necessary to switch between aluminum plates of different specifications or with different process requirements. If the pinch roll cannot be switched quickly, each switch requires a lot of time for manual disassembly and reinstallation, which will significantly increase equipment downtime and reduce overall production efficiency. To address the above problems, we have introduced a dual-station quick switching pinch roll device for aluminum plate rolling lines. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] The dual-station rapid switching pinch roll device disclosed in this utility model is mainly used in the scenario of pinch roll device.

[0023] Reference Figures 1 to 6 A dual-station quick-switching pinch roll device for an aluminum plate rolling line includes: a base 1, two mounting plates 2 fixedly connected to the top of the base 1, pinch rolls 3 equidistantly arranged between one side of the two mounting plates 2, and a drive assembly and a quick-switching assembly respectively provided at one end of the pinch rolls 3. The drive assembly includes a mounting rod 4, which is rotatably connected to one side of the mounting plate 2. A triangular plate 5 is fixedly connected to one end of the mounting rod 4, and a shaft 6 is rotatably connected to one side of the triangular plate 5. The outer side of the shaft 6 is fixedly connected to the inside of the pinch roller 3. A first motor 7 is provided on one side of the mounting plate 2. One end of the output shaft of the first motor 7 extends to one side of one of the triangular plates 5 and is fixedly connected to a first gear 8. A second gear 9 and a fastening nut 10 are threadedly connected to the outer side of the shaft body 6 respectively. One end of the fastening nut 10 abuts against one side of the second gear 9. The quick switching component includes a second motor 11, which is disposed on one side of the mounting plate 2. One end of the output shaft of the second motor 11 is fixedly connected to one side of the mounting rod 4. A positioning triangular block 12 is fixedly connected to the outside of the output shaft of the second motor 11, and positioning grooves 13 are provided at equal intervals on the outside of the positioning triangular block 12. A groove is provided on one side of the mounting plate 2. A fixing rod 14 is fixedly connected inside the groove. A slider 15 is slidably connected to the outside of the fixing rod 14. A positioning rod 16 is fixedly connected to one side of the slider 15. A spring 17 is provided on the outside of the fixing rod 14. The outside of the positioning rod 16 is slidably connected to the inside of the positioning groove 13.

[0024] In the above technical solution, considering that the pinch roll mechanism does not have a quick switching function, but in modern aluminum plate rolling production, it is often necessary to switch between aluminum plates of different specifications or with different process requirements. If the pinch roll cannot be switched quickly, each switch requires a lot of time for manual disassembly and reinstallation, which will significantly increase equipment downtime and reduce overall production efficiency. To solve this problem, the specific operation is as follows: By setting up a drive component and a quick switching component, first loosen the fastening nuts 10 on the shafts 6 at the top and bottom positions of the two sets of triangular plates 5, then move the corresponding second gear 9 to one side until it is fully engaged with the first gear 8, and then tighten the fastening nuts 10 to fix it. By starting the two sets of first motors 7 to drive the first gear 8 to rotate, the gear meshing relationship will drive one set of shafts 6 and pinch roll 3 to rotate. Then, the aluminum plate is placed between the two sets of pinch rolls 3. When it is necessary to adjust according to the requirements of the two sets of pinch rolls 3, the aluminum plate can be switched between the two sets of pinch rolls 3. When switching the clamping roller 3 for aluminum plates with different process requirements, the positioning rod 16 is pulled out of the positioning groove 13 by the quick switching component. Then, the second motor 11 is started, which drives the positioning triangular block 12, mounting rod 4, triangular plate 5 and clamping roller 3 to rotate. At this time, the positioning rod 16 is released, and the outer side of the positioning rod 16 contacts the outer side of the positioning triangular block 12. Under the thrust of its rotation, it will be lifted up, and the slider 15 moves inside the groove. The spring 17 is compressed. When the clamping roller 3 of the corresponding size rotates to the top, the positioning rod 16 corresponds to the positioning groove 13. Under the rebound of the spring 17, it re-enters the positioning groove 13. The second motor 11 stops rotating, thus completing the quick switching of the clamping roller 3. Then, the distance between the upper and lower clamping rollers 3 is adjusted, and the previously meshed second gear 9 is adjusted to be misaligned with the first gear 8. Then, the corresponding set of second gear 9 is adjusted to mesh with the first gear 8. By setting up a quick-change component, the pinch roller 3 can be switched in a short time without manual disassembly and reinstallation. This greatly reduces equipment downtime, enables the production line to operate more efficiently, and improves overall production efficiency. By setting up a drive component, precise control of each set of pinch rollers 3 can be achieved, ensuring the stability and accuracy of the aluminum plate during the conveying process.

[0025] Reference Figures 1 to 6 In a preferred embodiment, a bidirectional lead screw 18 and a slide bar 19 are respectively provided on one side of the mounting plate 2. Two positioning plates 20 are threadedly connected to the outer side of the bidirectional lead screw 18. The interior of the two positioning plates 20 is slidably connected to the outer side of the slide bar 19. A rotating torsion block 21 is fixedly connected to one end of the bidirectional lead screw 18. A protective pad is fixedly connected to one side of the positioning plate 20. By rotating the rotating torsion block 21, the bidirectional lead screw 18 can be driven to rotate. By using the restriction of the slide bar 19, the distance between the two sets of positioning plates 20 can be controlled to prevent the aluminum plate from deviating.

[0026] Working principle: When in use, first loosen the fastening nuts 10 on the top and bottom shafts 6 of the two sets of triangular plates 5, move the second gear 9 of the corresponding set to one side so that it can fully mesh with the first gear 8, then tighten the fastening nuts 10 to fix it, start the two sets of first motors 7, drive the first gear 8 to rotate, and with the help of the gear meshing relationship, make one set of shafts 6 and the pinch rollers 3 rotate, and place the aluminum plate between the two sets of pinch rollers 3 for conveying. When the pinch roller 3 needs to be switched according to different process requirements, the positioning rod 16 is pulled out of the positioning groove 13 by the quick switching assembly. The second motor 11 is started, which drives the positioning triangle block 12, mounting rod 4, triangle plate 5 and pinch roller 3 to rotate. At this time, the positioning rod 16 is released, and its outer side contacts the outer side of the positioning triangle block 12. It is pushed up by the rotational thrust, and the slider 15 moves in the groove. The spring 17 is compressed. When the corresponding size of the pinch roller 3 is rotated to the top, the positioning rod 16 corresponds to the positioning groove 13, and the spring 17 rebounds, causing the positioning rod 16 to re-enter the positioning groove 13. The second motor 11 stops rotating, completing the quick switching of the pinch roller 3. Finally, the previously meshed second gear 9 is adjusted to be misaligned with the first gear 8, and then the corresponding set of second gear 9 is adjusted to mesh with the first gear 8. The first motor 7 then drives the corresponding pinch roller 3 to rotate. All contents not described in detail in this specification are existing technologies known to those skilled in the art.
