Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and in particular to a winding equipment for traction steel strip. Background Technology

[0002] A winding machine is a device used to wind wire, strip, or sheet materials into coils of specific shapes and sizes. After production and processing, traction steel strips need to be packaged using winding equipment. In practical applications, the equipment typically requires the following technologies:

[0003] 1. Mounting bracket, used to install other components and ensure the stability of the equipment;

[0004] 2. The turntable is the main component for winding the traction steel belt;

[0005] 3. Fixing device to keep the steel strip stable during the winding process;

[0006] Currently, existing winding equipment (such as patent publication number: CN220467149U) discloses a winding device in which each set of drive components includes a lifting component and a clamping component. The lifting component is threadedly connected to the rotating rod and is located above the housing. The clamping component is fixedly connected to the lifting component. This method can effectively prevent the empty coil from deforming and being damaged during the upward movement, thereby improving the service life of the empty coil.

[0007] When winding traction steel belts, the belts are wound at a uniform speed using a drum. However, traction steel belts of different sizes have different transmission speeds, which can cause uneven tension during winding. Unstable tension can prevent the steel belt from being evenly wound on the drum during winding. Insufficient tension can cause the steel belt to loosen and become loose during transportation or storage. Excessive tension can cause the steel belt to become too tight, affecting the winding quality. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a winding device for traction steel strips, which solves the technical problem that when winding traction steel strips, the strips are wound at a uniform speed by a drum, but different sizes of traction steel strips have different transmission speeds, resulting in uneven tension during winding. This instability in tension prevents the steel strips from being evenly wound onto the drum during winding.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A winding device for traction steel strip includes a take-up drum and a steel strip body. At least two adjusting components are slidably installed inside the take-up drum. Each adjusting component includes a sliding plate, a connecting seat, an inclined push rod, and a nut slider. The two inclined push rods are inclined symmetrically at the side ends of the sliding plate. The end of each inclined push rod is rotatably connected to the nut slider. The surface of the take-up drum is provided with at least two grooves that mate with the sliding plate.

[0011] Preferably, a support cover plate is fixedly installed inside the winding drum, and a driven gear ring is fixedly installed at the side end of the support cover plate;

[0012] An adjustment frame is fixedly installed at the side end of the winding drum, and a telescopic rod is provided at the end of the adjustment frame;

[0013] The adjustment frame has a transmission rod that is engaged with the sliding plate. A transmission gear is fixedly installed at the top of the transmission rod, and the end of the transmission rod is connected to the output shaft of the motor through a slider coupling.

[0014] Preferably, a rotating lead screw that rotatably engages with the nut slider is rotatably mounted inside the support cover plate, and a main gear ring that engages with the transmission rod is fixedly mounted at the top end of the rotating lead screw;

[0015] The end of the rotating lead screw is sleeved inside the winding drum, and the surface of the rotating lead screw is provided with a thread to drive the nut slider to move. The thread helix angle of the rotating lead screw and the nut slider is less than the friction angle.

[0016] Compared with the prior art, the present invention has the following beneficial effects;

[0017] In this invention, a thrust is applied to the sliding plate, which simultaneously engages with the groove of the winding drum. Each sliding plate slides along the groove. By the synchronous movement of multiple sliding plates, the diameter of the winding drum is changed. When the diameter of the winding drum increases, the number of turns of the steel strip will decrease when winding the same length of steel strip. This allows for continuous and precise adjustment of the tension, maintaining uniform tension throughout the winding process and improving the quality of winding.

[0018] In this invention, the end of the transmission rod is connected to the output shaft of the motor via a slider coupling. While driving the transmission rod to rotate, the transmission rod can slide on one side of the output shaft, allowing the transmission gear at the top of the transmission rod to slide between the main gear ring and the driven gear ring. This can both drive the winding drum to rotate for winding and adjust the position of the sliding plate, thus centralizing the components and effectively reducing the size of the equipment.

[0025] This application provides a winding device for traction steel strips, which effectively solves the problem of uneven tension in the winding of traction steel strips when the strip is wound at a uniform speed by a drum. However, different sizes of traction steel strips have different transmission speeds, resulting in uneven tension. This instability causes the steel strip to not be evenly wound on the drum during winding. The device applies a pushing force to the sliding plates, which are engaged with the grooves of the winding drum. Each sliding plate slides along the groove, and the diameter of the winding drum is changed by the synchronous movement of multiple sliding plates. When the diameter of the winding drum increases, the number of turns of the steel strip is reduced when winding the same length of steel strip. This allows for continuous and precise adjustment of the tension, maintaining uniform tension throughout the winding process and improving the winding quality.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that when winding traction steel strips, the strips are wound at a uniform speed by the drum, but different sizes of traction steel strips have different transmission speeds, resulting in uneven tension during winding. Unstable tension causes the steel strips to not be evenly wound on the drum during winding. The overall idea is as follows:

[0028] To address the problems existing in the prior art, this utility model provides a winding device for traction steel strip, including a take-up drum 11 and a steel strip body 12. At least two adjusting components are slidably installed inside the take-up drum 11. Each adjusting component includes a sliding plate 19, a connecting seat 21, an inclined push rod 22, and a nut slider 23. The two inclined push rods 22 are symmetrically inclined at the side ends of the sliding plate 19, and the end of each inclined push rod 22 is rotatably connected to the nut slider 23. The surface of the take-up drum 11 is provided with at least two grooves that mate with the sliding plate 19. By pushing the nut slider 23, it slides inside the take-up drum 11. The two nut sliders 23 move symmetrically to each other, reducing the distance between them. The nut sliders 23 apply force to the inclined push rod 22 and push the sliding plate 19. At the same time, the sliding plate 19 engages with the groove of the winding drum 11, and each sliding plate 19 slides along the groove. By moving multiple sliding plates 19 synchronously, the diameter of the winding drum 11 is changed. When the diameter of the winding drum 11 increases, the number of turns of the steel strip will decrease when winding the same length of steel strip. This allows for continuous and precise adjustment of the tension, maintaining uniform tension throughout the winding process and improving the quality of winding.

[0029] A support cover plate 18 is fixedly installed inside the winding drum 11. A driven gear ring 17 is fixedly installed on the side end of the support cover plate 18. The transmission rod 13 is moved by the adjusting frame 14 so that the top end of the transmission rod 13 is connected to the driven gear ring 17. The end of the transmission rod 13 is connected to the motor. The rotating transmission rod 13 drives the winding drum 11 to rotate as a whole for winding.

[0030] An adjustment frame 14 is fixedly installed at the side end of the winding drum 11. A telescopic rod is provided at the end of the adjustment frame 14. By controlling the telescopic rod, the adjustment frame 14 is pushed to slide horizontally at the side end of the winding drum 11. The adjustment frame 14 moves and drives the driven gear ring 17 and the rotating screw 15 respectively.

[0031] The adjustment frame 14 has a transmission rod 13 that is engaged with the sliding plate 19. A transmission gear is fixedly installed at the top of the transmission rod 13. The end of the transmission rod 13 is connected to the output shaft of the motor through a slider coupling. While driving the transmission rod 13 to rotate, the transmission rod 13 can slide on one side of the output shaft, allowing the transmission gear at the top of the transmission rod 13 to slide between the main gear ring 16 and the driven gear ring 17. This can drive the rotation of the winding drum 11 and adjust the position of the sliding plate 19, thus centralizing the components and reducing the volume.

[0032] The support cover plate 18 is rotatably mounted with a rotating screw 15 that mates with the nut slider 23. The top of the rotating screw 15 is fixedly mounted with a main gear ring 16 that mates with the transmission rod 13. The transmission rod 13 is pushed by the adjusting bracket 14, causing the top of the transmission rod 13 to slide away from the surface of the driven gear ring 17. At the same time, the transmission rod 13 continues to move in the opposite direction and mates with the main gear ring 16. The rotating transmission rod 13 drives the main gear ring 16 to rotate. Meanwhile, the main gear ring 16 is fixedly connected to the rotating screw 15. The transmission rod 13 drives the rotating screw 15 to rotate inside the winding drum 11.

[0033] The end of the rotating screw 15 is sleeved inside the winding drum 11. The surface of the rotating screw 15 is provided with threads to drive the nut slider 23 to move. The rotating screw 15 applies force to the two nut sliders 23. The nut sliders 23 are symmetrically designed. The internal threads of the two nut sliders 23 are opposite. The rotating screw 15 drives the two nut sliders 23 to move synchronously, moving closer or further away from each other.

[0034] The thread helix angle of the rotating lead screw 15 and the nut slider 23 is smaller than the friction angle. When there is no external force driving the rotating lead screw 15, the nut slider 23 will not move on its own due to axial force and can remain stationary at any position, thereby achieving self-locking of the rotating lead screw 15 and ensuring the stability after adjustment.

[0035] Working principle:

[0036] The first step is to fix one end of the steel strip body 12 to the surface of the take-up drum 11. The transmission rod 13 is moved by the adjusting frame 14 so that the top end of the transmission rod 13 aligns with the driven gear ring 17. The end of the transmission rod 13 is connected to the motor. The rotating transmission rod 13 drives the take-up drum 11 to rotate as a whole for winding. The end of the transmission rod 13 is connected to the output shaft of the motor through a slider coupling. While driving the transmission rod 13 to rotate, the transmission rod 13 can slide on one side of the output shaft, allowing the transmission gear at the top end of the transmission rod 13 to slide between the main gear ring 16 and the driven gear ring 17. This can drive the rotation of the take-up drum 11 and adjust the position of the sliding plate 19, thus centralizing the components and reducing the volume.

[0037] The second step involves pushing the transmission rod 13 via the adjusting bracket 14, causing the top end of the transmission rod 13 to slide away from the surface of the driven gear ring 17. Simultaneously, the transmission rod 13 continues to move in the opposite direction and engages with the main gear ring 16. The rotating transmission rod 13 drives the main gear ring 16 to rotate, while the main gear ring 16 is fixedly connected to the rotating lead screw 15. The transmission rod 13 drives the rotating lead screw 15 to rotate inside the take-up drum 11, pushing the nut slider 23 to slide inside the take-up drum 11, causing the two nut sliders 23 to move symmetrically relative to each other. As the spacing of 3 decreases, the nut slider 23 applies a force to the inclined push rod 22, which in turn applies a thrust to the sliding plate 19. At the same time, the sliding plate 19 engages with the groove of the winding drum 11. Each sliding plate 19 slides along the groove. By moving multiple sliding plates 19 synchronously, the diameter of the winding drum 11 is changed. When the diameter of the winding drum 11 increases, the number of turns of the steel strip will decrease when winding the same length of steel strip. This allows for continuous and precise adjustment of the tension, maintaining uniform tension throughout the winding process and improving the quality of winding.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
