[0026] As Figures 1 to 5 shown, an adjusting structure for the rocker arm of an aramid staple fiber crimper includes two rocker arms 1. A shaft hole 2 is penetrated through the surface of the rocker arm 1. A hockey stick 3 is arranged between the two rocker arms 1. A clamping assembly 4 for limiting both ends of the hockey stick 3 is arranged on the surface of the rocker arm 1. A locking assembly 5 for controlling the operation of the clamping assembly 4 is also arranged on the surface of the rocker arm 1. A support plate 7 is fixedly connected to the bottom of the rocker arm 1. A driving assembly 6 for controlling the rotation of the hockey stick 3 is installed on the surface of the support plate 7. More specifically, it is connected to the driving shaft of the crimper through the shaft hole 2 to realize the installation and fixation of the rocker arm 1. By operating the driving assembly 6, the rotation of the hockey stick 3 can be controlled. When the hockey stick 3 needs to be disassembled, manually operate the locking assembly 5 to release the limiting effect of the clamping assembly 4, and then pull up the hockey stick 3 to quickly disassemble it. After replacing the new hockey stick 3, control the clamping assembly 4 to operate through the locking assembly 5 to fix the hockey stick 3 again, and the replacement can be completed.

[0027] The clamping assembly 4 includes a fixed seat 401, and the fixed seat 401 is rotatably connected to the left rocker arm 1. Cross blocks 402 are fixedly connected to both ends of the hockey stick 3, and the cross blocks 402 are movably inserted into the fixed seat 401. A placement groove 405 is opened on the top surface of the right rocker arm 1, and the hockey stick 3 is located inside the placement groove 405. A gland 403 is arranged on the right side of the hockey stick 3. A docking seat 404 is rotatably arranged on the inner wall of the gland 403, and the docking seat 404 is movably inserted into the cross block 402. It should be noted that align the cross block 402 at the left end of the hockey stick 3 with the fixed seat 401 and insert it. Place the right end of the hockey stick 3 into the placement groove 405. Control the gland 403 to move to the left through the locking assembly 5, so that the cross block 402 on the right side of the hockey stick 3 enters the inner wall of the docking seat 404, and the installation and fixation of the hockey stick 3 can be achieved. By operating in the reverse direction, the hockey stick 3 can be quickly disassembled and replaced.

[0028] The locking component 5 includes a threaded post 503, and the threaded post 503 is rotatably connected to the right rocker arm 1. A connecting rod 506 is threadedly connected to the surface of the threaded post 503, and the end of the connecting rod 506 is fixedly connected to the gland 403. A sliding post 505 is fixedly connected to the surface of the rocker arm 1, and the sliding post 505 is slidably connected to the connecting rod 506. The locking component 5 further includes an adjusting component for controlling the rotation of the threaded post 503. More specifically, the adjusting component controls the rotation of the threaded post 503. Under the action of the thread, the connecting rod 506 is driven to slide along the surface of the sliding post 505, so as to control the movement of the gland 403, and realize the clamping and fixing of the hockey stick 3 or the release of the limit on the hockey stick 3.

[0029] The adjusting component includes a worm 501, and the worm 501 is rotatably connected to the right rocker arm 1. A knob 502 is fixedly connected to the top of the worm 501. A worm gear 504 is fixedly sleeved on the surface of the threaded post 503, and the worm gear 504 meshes with the worm 501. It should be noted that by rotating the knob 502, the worm 501 is driven to rotate, and the worm 501 will drive the worm gear 504 meshing with it to rotate, thereby controlling the rotation of the threaded post 503. The worm 501 and the worm gear 504 can achieve self-locking, so as to ensure that the threaded post 503 cannot rotate by itself.

[0030] The driving component 6 includes a motor 601, and the motor 601 is fixedly installed on the surface of the support plate 7. The output end of the motor 601 is fixedly connected to a rotating shaft 602, and the end of the rotating shaft 602 is fixedly connected to a driving wheel 603. A driven wheel 605 is fixedly connected to the left end of the fixed seat 401, and a belt 604 meshes between the driving wheel 603 and the driven wheel 605. More specifically, the motor 601 drives the rotating shaft 602 to rotate, thereby driving the driving wheel 603 to rotate. Under the driving action of the belt 604, the driven wheel 605 will be driven to rotate, so as to control the rotation of the fixed seat 401 and the hockey stick 3.

[0031] Cross slots adapted to the cross block 402 are formed on the surfaces of the fixed seat 401 and the docking seat 404. It should be noted that during the installation process, the cross block 402 is inserted into the cross slot, so that there is no relative rotation between the cross block 402 and the fixed seats 401 and the docking seat 404 on both sides, thereby ensuring the stability of the installation of the hockey stick 3.

[0032] In summary: By connecting the shaft hole 2 with the drive shaft of the coiling machine, the installation and fixation of the rocker arm 1 are realized. By operating the drive assembly 6, the rotation of the hockey stick 3 can be controlled. When the hockey stick 3 needs to be disassembled, the locking assembly 5 is manually operated to release the limiting effect of the clamping assembly 4, and the hockey stick 3 can be quickly disassembled by pulling it upward. After replacing the new hockey stick 3, the clamping assembly 4 is controlled to operate by the locking assembly 5 to fix the hockey stick 3 again, and the replacement can be completed. In use, the effect of facilitating the quick replacement of the hockey stick on the coiling machine rocker arm is achieved. The operation is very simple, and there is no need to adjust the connection with the belt, effectively improving the replacement efficiency.
