At this point, the take-up shaft can be removed from the mounting slots of the frame. The clutch actuator of this invention has its drive end coaxially connected to the clutch shaft. When the clutch actuator drives the clutch shaft to move, the clutch shaft will not be subjected to radial force, which makes the movement of the clutch shaft stable and less prone to jamming. This facilitates the smooth engagement or disengagement of the clutch shaft with the clutch coupling. The structure is simple and the cost is low.

Technical Field
[0001] This utility model relates to the field of winding device technology, and in particular to a clutch-type winding power transmission mechanism. Background Technology

The clutch shaft moves from the retracted position to the extended position. The driving component includes a cylinder and a push plate connected to the output end of the cylinder. The cylinder drives the push plate to move axially along the clutch shaft, so that the push plate can abut against the clutch shaft and drive the clutch shaft from the extended position to the retracted position. The reset component is a spring, which is located at the end of the clutch shaft away from the first engagement part. One end of the spring abuts or is fixed to the clutch shaft, and the other end of the spring abuts or is fixed to the transmission shaft. Although this structure also discloses the engagement connection between the clutch shaft and the rotating shaft, the reciprocating movement of the clutch shaft requires the cooperation of the driving component and the reset component. The driving component includes a cylinder and a push plate. The cylinder pushes the clutch shaft via the push plate. The cylinder is located on one side of the clutch shaft, and the clutch shaft is easily subjected to the radial force of the push plate, which makes the clutch shaft prone to jamming or wear during movement. Moreover, the structure is complex and costly.
[0003] Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

Mounting grooves are provided on both side plates of the frame. The two mounting sleeves are detachably installed in the two mounting grooves.

[0015] The beneficial effects of this utility model are as follows: In practical applications, the take-up drum is fitted over the take-up shaft, and two mounting sleeves are respectively fitted over both ends of the take-up shaft, allowing the take-up shaft to rotate relative to the two mounting sleeves. The two mounting sleeves are then installed in two mounting slots. When the take-up shaft needs to be driven to rotate, the clutch actuator drives the clutch shaft to move relative to the rotating sleeves towards the clutch coupling until the clutch shaft and clutch coupling are detachably engaged. Then, the drive module drives the rotating sleeves to rotate, which in turn drives the clutch shaft to rotate synchronously.

[0020] like Figures 1 to 3 As shown, this utility model provides a clutch-type winding power transmission mechanism, which includes a frame 1, a winding shaft 2, a clutch coupling 3, a mounting bracket 4, a rotation drive module 5, a rotating sleeve 6, a clutch shaft 7, a clutch driver 8, and two mounting sleeves 9. Both side plates of the frame 1 are provided with mounting grooves 10. The two mounting sleeves 9 are detachably installed in the two mounting grooves 10. Both ends of the winding shaft 2 are rotatably connected to the two mounting sleeves 9. The clutch coupling 3 is installed at one end of the winding shaft 2 and located outside the mounting sleeve 9. The mounting bracket 4 is installed outside one side plate of the frame 1 and is correspondingly arranged with respect to the mounting groove 10. The rotating sleeve 6... The clutch shaft 7 is rotatably connected to the mounting bracket 4 and is installed inside the rotating sleeve 6, allowing it to move horizontally relative to the rotating sleeve 6. The clutch actuator 8 is installed on the mounting bracket 4, with one end of the clutch shaft 7 coaxially mounted to the drive end of the clutch actuator 8, allowing the clutch shaft 7 to rotate relative to the drive end of the clutch actuator 8. The other end of the clutch shaft 7 is used to engage with the clutch coupling 3. The rotation drive module 5 is used to drive the rotating sleeve 6 to rotate, and the clutch actuator 8 is used to drive the clutch shaft 7 to move closer to or away from the clutch coupling 3. The drive end of the clutch actuator 8, the clutch shaft 7, the rotating sleeve 6, the clutch coupling 3, and the take-up shaft 2 are coaxially arranged. Specifically, the take-up shaft 2 is an air-expanding shaft, and the mounting groove 10 is a U-shaped groove.
[0021] In practical applications, the take-up drum is fitted over the take-up shaft 2, and two mounting sleeves 9 are respectively fitted over both ends of the take-up shaft 2, allowing the take-up shaft 2 to rotate relative to the two mounting sleeves 9. The two mounting sleeves 9 are then installed in the two mounting slots 10. When the take-up shaft 2 needs to be rotated, the clutch actuator 8 drives the clutch shaft 7 to move relative to the rotating sleeve 6 towards the clutch coupling 3 until the clutch shaft 7 and clutch coupling 3 are detachably engaged. Then, the drive module 5 drives the rotating sleeve 6 to rotate, which in turn drives the clutch shaft 7 to rotate synchronously. The rotating clutch shaft 7 drives the clutch coupling 3 to rotate synchronously, which in turn drives the take-up shaft 2 to rotate synchronously. The rotating take-up shaft 2 then drives the take-up drum to rotate synchronously, and the rotating take-up drum winds up the material strip. When the take-up shaft 2 needs to be replaced, the clutch actuator 8 drives the clutch shaft 7 to move away from the clutch coupling 3, causing the clutch shaft 7 to separate from the clutch coupling 3. At this point, the take-up shaft 2 can be removed from the mounting slot 10 of the frame 1. The drive end of the clutch driver 8 of this utility model is coaxially connected to the clutch shaft 7. When the clutch driver 8 drives the clutch shaft 7 to move, the clutch shaft 7 will not be subjected to radial force, which makes the movement of the clutch shaft 7 stable and less prone to jamming. This facilitates the smooth engagement or disengagement of the clutch shaft 7 with the clutch coupling 3. The structure is simple and the cost is low.
[0022] Specifically, the clutch actuator 8 can be a cylinder. The piston rod of the cylinder extends and retracts to drive the clutch shaft 7 to reciprocate.
[0023] Specifically, the take-up shaft 2 is rotatably connected to the mounting sleeve 9 via the bearing 12. This structural design improves the stability of the take-up shaft 2 rotating relative to the mounting sleeve 9.
[0024] In this embodiment, the drive end of the clutch actuator 8 is equipped with a transmission shaft 11, which is rotatably connected to the clutch shaft 7 via a bearing 12. This structural design facilitates the connection between the clutch actuator 8 and the clutch shaft 7, ensuring that while the clutch actuator 8 can drive the clutch shaft 7 to move, the clutch shaft 7 can rotate relative to the clutch actuator 8.
[0025] In this embodiment, a guide block 13 is installed on the peripheral side wall of the clutch shaft 7, and a guide groove 14 is recessed on the inner wall of the rotating sleeve 6. The guide block 13 and the guide groove 14 are slidably engaged. During the movement of the clutch shaft 7 relative to the rotating sleeve 6, the guide block 13 slides along the guide groove 14, ensuring that the clutch shaft 7 can move relative to the rotating sleeve 6 while simultaneously rotating synchronously with the rotating sleeve 6.
[0026] In this embodiment, a clutch groove 15 is provided at the end of the clutch shaft 7 away from the clutch driver 8, and a clutch engagement joint 3 is provided with a clutch protrusion 16, which is adapted to fit the clutch groove 15. Specifically, the clutch groove 15 is a non-circular groove, and the clutch protrusion 16 is a non-circular block. When the clutch shaft 7 and the clutch engagement joint 3 are engaged, the clutch protrusion 16 of the clutch shaft 7 is inserted into the clutch groove 15, so that the clutch shaft 7 can drive the clutch engagement joint 3 and the take-up shaft 2 to rotate synchronously.
[0027] In this embodiment, the outer peripheral wall of the mounting sleeve 9 is recessed with an annular groove 17; when the mounting sleeve 9 is installed in the mounting groove 10, the side plate of the frame 1 can be locked in the annular groove 17. This structural design allows the mounting sleeve 9 to be stably and accurately installed in the mounting groove 10 of the frame 1.
[0028] In this embodiment, the rotation drive module 5 includes a rotation driver 18 mounted on the frame 1 and a transmission assembly 19 that is drively connected between the rotating end of the rotation driver 18 and the rotating sleeve 6. In practical applications, the rotation driver 18 drives the rotating sleeve 6 to rotate via the transmission assembly 19, thereby stabilizing the rotation of the rotating sleeve 6. The transmission ratio can be adjusted by changing the specifications of the transmission assembly 19 to meet the needs of different application scenarios.
[0029] In this embodiment, the transmission assembly 19 includes a driving wheel 20 mounted on the rotating end of the rotary driver 18, a driven wheel 21 mounted on the rotating sleeve 6, and a transmission belt 22 connecting the driving wheel 20 and the driven wheel 21. Specifically, the rotary driver 18 can be a motor. In practical applications, the rotary driver 18 drives the driving wheel 20 to rotate, the rotating driving wheel 20 drives the driven wheel 21 to rotate via the transmission belt 22, and the rotating driven wheel 21 drives the rotating sleeve 6 to rotate. This structural design reduces the weight requirements of the motor, resulting in low cost and minimal vibration.
[0030] In this embodiment, both side plates of the frame 1 are equipped with limiting modules 23. Each limiting module 23 corresponds to one of the two mounting sleeves 9. The limiting modules 23 are used to confine the mounting sleeves 9 within the mounting grooves 10. In practical applications, after the mounting sleeves 9 are installed in the mounting grooves 10, the limiting modules 23 confine the mounting sleeves 9 within the mounting grooves 10, preventing them from loosening or detaching from the mounting grooves 10. When the take-up shaft 2 needs to be replaced, the limiting modules 23 release their confinement over the mounting sleeves 9, allowing the take-up shaft 2 to remove the mounting sleeves 9 from the mounting grooves 10.
[0031] In this embodiment, the limiting module 23 includes a limiting cylinder 24 mounted on the side plate of the frame 1 and a limiting block 25 mounted on the piston rod of the limiting cylinder 24. The limiting block 25 is used to limit the mounting sleeve 9 within the mounting groove 10. In practical applications, when the mounting sleeve 9 is installed in the mounting groove 10, the piston rod of the limiting cylinder 24 extends to drive the limiting block 25 to move closer to the mounting sleeve 9 until the limiting block 25 abuts against the mounting sleeve 9 to limit the mounting sleeve 9 within the mounting groove 10. When it is necessary to remove the mounting sleeve 9, the piston rod of the limiting cylinder 24 retracts to drive the limiting block 25 away from the mounting sleeve 9 until the limiting block 25 releases the mounting sleeve 9, and the mounting sleeve 9 can then be removed from the mounting groove 10.
[0032] Specifically, the outer peripheral wall of the mounting sleeve 9 is recessed with a limiting groove 26, which is an annular groove, allowing the limiting block 25 to extend into it. In practical applications, when the limiting block 25 extends into the limiting groove 26 and abuts against its inner wall, it limits the mounting sleeve 9 within the mounting groove 10. The cooperation between the limiting block 25 and the limiting groove 26 improves the stability of the mounting sleeve 9 within the limiting groove 26.
[0033] Specifically, the rotating sleeve 6 is rotatably connected to the mounting bracket 4 via the bearing 12. This structural design improves the stability of the rotating sleeve 6 relative to the mounting bracket 4 during rotation.
[0034] All technical features in this embodiment can be freely combined according to actual needs.
[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
