Description

Technical Field

[0001] This utility model relates to the field of aluminum coil unwinding technology, specifically to an online paper receiving device for an unwinding machine. Background Technology

[0002] The main function of an uncoiler is to smoothly unwind the coil, providing an efficient and stable supply of materials for subsequent production and processing steps. The uncoiler supports the steel coil by tightening the inner hole of the coil, and feeds the head of the coil into the leveling machine by rotating it in conjunction with the straightening machine. The uncoiler can also perform upper unwinding while maintaining the rear tension of the coil.

[0003] During aluminum coil production, in order to protect the surface quality of the aluminum coil and reduce the phenomenon of interlayer unwinding and sticking, paper is usually wound between each layer of the aluminum coil during tension bending and straightening to achieve the effect of protecting the surface quality of the aluminum coil. However, the existing technology uses an uncoiler to remove the paper wound between the layers of the aluminum coil when unwinding the aluminum coil in order to perform longitudinal cutting. This has the drawback of making it inconvenient to collect and recycle the paper wound between the layers of the aluminum coil, which not only makes the on-site working environment messy, but also causes paper waste and increases the production cost of aluminum coil. Summary of the Invention

[0004] This invention addresses the problem of inconvenience in collecting and recycling the paper wound between layers of aluminum coils when unwinding them using existing uncoilers. It provides an online paper collection device for uncoilers that facilitates the collection and recycling of paper wound between aluminum coil layers. This device allows for simultaneous collection and recycling of the paper while the uncoiler is unwinding the aluminum coil, resulting in a clean and tidy working environment. Furthermore, the collected paper can be reused, reducing the production cost of aluminum coils.

[0005] To achieve the above objectives, the technical solution of this utility model is: an online paper take-up device for an unwinding machine, comprising a support frame, a movable seat slidably disposed on the top of the support frame, a transmission component and a support seat respectively disposed on the top of both ends of the movable seat, a clamping component being drivenly connected to the transmission component, and a clamping component also disposed on the top of the support seat, with a take-up shaft disposed between the two clamping components. The movable seat can move on the support frame to adjust the position of the transmission component and the support seat, so that the take-up shaft clamped by the two clamping components corresponds to the unwinding machine's tension shaft, so that the take-up shaft can collect and recycle the paper wound between the aluminum coil layers. The two clamping components provide clamping and fixing to the take-up shaft, while also facilitating the rotation of the take-up shaft to collect and recycle the paper wound between the aluminum coil layers.

[0006] The tightening assembly includes a steel sleeve and a tightening shaft. The tightening shaft is rotatably fitted inside the steel sleeve, and one end of the tightening shaft is fixedly connected to a tightening seat for tightening the take-up shaft. Under the action of the tightening seats at the ends of the tightening shafts of the two tightening assemblies, the take-up shaft is tightened and fixed; and the cooperation between the tightening shaft and the steel sleeve facilitates the rotation of the take-up shaft to collect and recycle the paper wound between the layers of the aluminum roll.

[0007] The top of the movable seat is also provided with a drive mechanism, which is connected to the clamping shaft of one of the clamping components. The drive mechanism drives the clamping shaft of one of the clamping components to rotate, so that the clamping shaft drives the paper take-up shaft to rotate to collect and recycle the paper wound between the layers of the aluminum roll.

[0008] Furthermore, bases are fixedly installed at the bottom of both ends of the support frame; slide rails are symmetrically arranged at the top of the support frame, and sliders corresponding to the slide rails are symmetrically arranged at the bottom of both ends of the movable seat. The sliders are slidably mounted on the slide rails. The bases provide support for the support frame, and the support frame provides support for the movable seat. The cooperation between the slide rails and sliders allows the movable seat to slide on the support frame, facilitating the adjustment of the movable seat's position so that the take-up shaft aligns with the unwinding machine's tension shaft, allowing the take-up shaft to collect and recycle the paper wound between the aluminum coil layers.

[0009] Furthermore, the transmission assembly includes a U-shaped seat and a lead screw. The U-shaped seat is fixedly mounted on the top of the movable seat, and a bearing is provided on the vertical part of the U-shaped seat. The lead screw is rotatably connected to the U-shaped seat through the bearing, and the lead screw can rotate through the action of the bearing.

[0010] Furthermore, one end of the lead screw extends to the outside of the U-shaped seat and is fixedly connected to a handwheel, and a transmission block is drivenly connected to the lead screw; a steel sleeve of one of the tightening components is fixedly installed on the top of the transmission block. The handwheel facilitates the operator to rotate the lead screw, and the rotation of the lead screw can drive the transmission block to move axially on the lead screw, which can drive the tightening component to move, thereby achieving the effect of tightening or loosening the paper take-up shaft.

[0011] Furthermore, the steel sleeve is symmetrically equipped with self-aligning roller bearings inside, and the tightening shaft is rotatably connected to the steel sleeve through the self-aligning roller bearings. The self-aligning roller bearings facilitate the rotation of the tightening shaft inside the steel sleeve, thereby facilitating the tightening shaft to drive the paper take-up shaft to rotate.

[0012] Furthermore, a clamping groove is provided on the side of the clamping seat near the paper take-up shaft. The two ends of the paper take-up shaft are respectively inserted into the clamping grooves of the two clamping seats. The two clamping seats can clamp and fix the paper take-up shaft through the clamping grooves, so as to facilitate the clamping shaft to drive the paper take-up shaft to rotate.

[0013] Furthermore, the drive mechanism includes a torque motor and a belt drive assembly. The torque motor is fixedly mounted on the top of the movable seat. The belt drive assembly includes a driving pulley, a driven pulley, and a drive belt. The output end of the torque motor is connected to the driving pulley. One end of the clamping shaft of one of the clamping components is connected to the driven pulley. The driving pulley is driven by the drive belt. The torque motor can drive the clamping shaft of one of the clamping components to rotate via the belt drive assembly, thereby driving the paper take-up shaft to rotate.

[0014] The beneficial effects of this utility model through the above technical solution are as follows: This utility model has a reasonable structure and good performance. It facilitates the collection and recycling of paper wound between aluminum coil layers. While the uncoiler is unwinding the aluminum coil, it can collect and recycle the paper wound between the aluminum coil layers online, making the on-site working environment clean and tidy and reducing the labor intensity of the staff. At the same time, the collected and recycled paper can be reused, reducing the cost of aluminum coil production.

[0015] The slider at the bottom of the movable seat of this utility model cooperates with the slide rail at the top of the support frame, so that the movable seat can move at the top of the support frame, so as to adjust the position of the movable seat so that the paper take-up shaft corresponds to the unwinding machine expansion shaft, ensuring that the paper take-up shaft can collect and recycle the paper wound between the aluminum coil layers.

[0016] This invention uses a transmission assembly to drive one of the clamping assemblies to move axially, achieving the effect of clamping or loosening the take-up shaft with two clamping assemblies. This facilitates the rotation of the take-up shaft to collect and recycle the paper wound between the layers of the aluminum roll, and also makes it easy to remove the paper roll collected by the take-up shaft. The self-aligning roller bearing of the clamping assembly facilitates the rotation of the clamping shaft within the steel sleeve, while the clamping seats of the two clamping assemblies clamp and fix the take-up shaft through the clamping grooves. This allows the drive mechanism to drive the take-up shaft to rotate via the clamping shaft to collect and recycle the paper wound between the layers of the aluminum roll.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-2 As shown, an online paper take-up device for an unwinding machine includes a support frame 1. A movable seat 4 is slidably disposed on the top of the support frame 1. A transmission component and a support seat 6 are respectively disposed on the top of both ends of the movable seat 4. A clamping component is connected to the transmission component. A clamping component is also disposed on the top of the support seat 6. A paper take-up shaft 16 is disposed between the two clamping components. In this embodiment, the support frame 1 is constructed by welding and fixing four U-shaped steels. The movable seat 4 can slide on the top of the support frame 1. The operator can manually push the movable seat 4 to adjust its position on the top of the support frame 1, thereby adjusting the position of the transmission component and the support seat 6. This achieves the effect of adjusting the position of the take-up shaft 16 between the two clamping components, ensuring that the take-up shaft 16 corresponds to the tension shaft of the unwinding machine, so that the take-up shaft 16 can collect and recycle the paper wound between the layers of the aluminum roll. The support seat 6 supports the clamping component. The transmission component can drive the clamping component connected to it to move. Through the movement of one of the clamping components, the two clamping components can clamp and fix the take-up shaft 16. The take-up shaft 16 can be a paper sleeve or a PVC pipe.

[0020] The clamping assembly includes a steel sleeve 12 and a clamping shaft 14. The clamping shaft 14 is rotatably sleeved inside the steel sleeve 12. One end of the clamping shaft 14 is fixedly connected to a clamping seat 15 for clamping the take-up shaft 16. In this embodiment, the clamping seat 15 is installed at the end of the clamping shaft 14 near the take-up shaft 16. The clamping shafts 14 of the two clamping assemblies clamp and fix the take-up shaft 16 through the action of the clamping seat 15. The clamping shaft 14 can rotate inside the steel sleeve 12 so that the clamping shaft 14 can drive the take-up shaft 16 to rotate.

[0021] The top of the movable seat 4 is also provided with a drive mechanism, which is connected to the clamping shaft 14 of one of the clamping components. In this embodiment, the drive mechanism drives the clamping shaft 14 of one of the clamping components to rotate, thereby achieving the effect of the clamping shaft 14 driving the paper take-up shaft 16 to rotate.

[0022] The support frame 1 has bases 2 fixedly installed at both ends of its bottom; the support frame 1 has symmetrically arranged slide rails 3 at its top, and the movable seat 4 has symmetrically arranged sliders 5 at both ends of its bottom, corresponding to the slide rails 3. The sliders 5 are slidably mounted on the slide rails 3. In this embodiment, there are two bases 2 at both ends of the support frame 1, which support the support frame 1; there are two slide rails 3 at the top of the support frame 1, and there are two sliders 5 at both ends of the movable seat 4, with each slider 5 corresponding to one of the two slide rails 3. The cooperation between the sliders 5 and the slide rails 3 allows the operator to push the movable seat 4 to slide on the top of the support frame 1 to adjust its position.

[0023] The transmission assembly includes a U-shaped seat 7 and a lead screw 9. The U-shaped seat 7 is fixedly mounted on the top of the movable seat 4, and a bearing 8 is provided on the vertical part of the U-shaped seat 7. The lead screw 9 is rotatably connected to the U-shaped seat 7 through the bearing 8. In this embodiment, both ends of the lead screw 9 are rotatably connected to the vertical part of the U-shaped seat 7 through the bearing 8, so that the lead screw 9 can rotate within the U-shaped seat 7 under the action of the bearing 8.

[0024] One end of the lead screw 9 extends to the outside of the U-shaped seat 7 and is fixedly connected to a handwheel 10. A transmission block 11 is drivenly connected to the lead screw 9. A steel sleeve 12 of one of the clamping components is fixedly installed on the top of the transmission block 11. In this embodiment, the handwheel 10 facilitates the rotation of the lead screw 9 by the operator. When the lead screw 9 rotates, the transmission block 11 moves axially on the lead screw 9. The transmission block 11 synchronously drives the steel sleeve 12 connected to it to move. The steel sleeve 12 drives the clamping shaft 14 and the clamping seat 15 to move, so as to clamp and fix or loosen the paper take-up shaft.

[0025] The steel sleeve 12 is symmetrically equipped with self-aligning roller bearings 13 inside, and the tightening shaft 14 is rotatably connected to the steel sleeve 12 through the self-aligning roller bearings 13. In this embodiment, there are two self-aligning roller bearings 13 inside the steel sleeve 12. The self-aligning roller bearings 13 facilitate the rotation of the tightening shaft 14 inside the steel sleeve 12, thereby facilitating the tightening shaft 14 to drive the paper take-up shaft 16 to rotate, so as to collect the paper wound between the layers of the aluminum roll; both ends of the tightening shaft 14 extend to the outside of the steel sleeve 12.

[0026] The clamping seat 15 has a clamping groove on the side near the take-up shaft 16, and both ends of the take-up shaft 16 are respectively inserted into the clamping grooves of the two clamping seats 15. In this embodiment, the clamping groove can be square or pyramidal in shape. The end of the take-up shaft 16 matches the clamping groove. Through the action of the clamping groove on the clamping seat 15, the clamping shafts 14 of the two clamping components can clamp and fix the take-up shaft 16, and at the same time, the clamping shafts 14 of the clamping components can drive the take-up shaft 16 to rotate.

[0027] The drive mechanism includes a torque motor 17 and a belt drive assembly. The torque motor 17 is fixedly mounted on the top of the movable seat 4. The belt drive assembly includes a drive pulley 18, a driven pulley 19, and a transmission belt 20. The output end of the torque motor 17 is connected to the drive pulley 18. One end of the clamping shaft 14 of one of the clamping components is connected to the driven pulley 19. The drive pulley 18 is driven by the transmission belt 20 to the driven pulley 19. In this embodiment, when the torque motor 17 is turned on, its output end drives the drive pulley 18 to rotate. The drive pulley 18 drives the driven pulley 19 to rotate via the transmission belt 20. The driven pulley 19 drives the clamping shaft 14 to rotate. The clamping shaft 14 then drives the take-up shaft 16 to rotate via the clamping seat 15.

[0028] The working principle of this utility model is as follows: The paper take-up device is installed at the front end of the uncoiler, that is, at the front end of the uncoiler's tension shaft. The direction of unwinding the aluminum coil is opposite to the direction of paper take-up. Then, the paper take-up shaft 16 is installed between the two clamping components. That is, the operator can rotate the lead screw 9 through the handwheel 10. The lead screw 9 drives the transmission block 11 to move away from the support seat 6. The transmission block 11 drives the steel sleeve 12 to move synchronously, so that the paper take-up shaft 16 can be placed on the clamping seat 15 at the end of the clamping shaft 14 of the two clamping components. Then, one end of the take-up shaft 16 is inserted into the tightening groove on the tightening seat 15 of the tightening assembly at the top of the support base 6. Then, the screw 9 is rotated in the opposite direction. The screw 9 drives the transmission block 11 to move towards the support base 6. The transmission block 11 drives the steel sleeve 12 to move synchronously. The steel sleeve 12 drives the tightening seat 15 to move towards the take-up shaft 16 through the tightening shaft 14 until the other end of the take-up shaft 16 is inserted into the tightening groove on the tightening seat 15, and the two tightening seats 15 clamp and fix the take-up shaft 16.

[0029] Then, the operator can manually push the movable seat 4 to slide it on top of the support frame 1. The slider 5 at the bottom of the movable seat 4 slides on the slide rail 3 at the top of the support frame 1 to adjust the position of the movable seat 4 on top of the support frame 1. When the paper take-up shaft 16 corresponds to the tension shaft of the unwinding machine, the operator can stop pushing the movable seat 4.

[0030] When the uncoiler unwinds the aluminum coil, the torque motor 17 is turned on. The output end of the torque motor 17 drives the drive pulley 18 to rotate. The drive pulley 18 drives the driven pulley 19 to rotate through the transmission belt 20. The driven pulley 19 drives the top tension shaft 14 to rotate. The top tension shaft 14 then drives the take-up shaft 16 to rotate through the top tension seat 15. During the unwinding of the aluminum coil, the take-up shaft 16 rotates online to collect and recycle the paper wound between the layers of the aluminum coil, and winds the collected paper onto the take-up shaft 16.

[0031] When it is necessary to remove the paper roll wound on the take-up shaft 16, the operator can turn the screw 9 again through the handwheel 10. The screw 9 drives the transmission block 11 to move away from the support seat 6. The transmission block 11 drives the steel sleeve 12 to move synchronously, so that the clamping seat 15 at the end of the clamping shaft 14 of the two clamping components loosens the take-up shaft 16, and then the paper roll wound on the take-up shaft 16 can be removed.

[0032] The embodiments described above are merely preferred embodiments of the utility model and are not intended to limit the scope of the utility model. Therefore, all equivalent changes or modifications made to the technical solutions described in the scope of the utility model patent application should be included within the scope of the utility model patent application.
