[0028] Support frames 21 are installed on both sides of the bottom of the machine base 7 , a feed roller 14 is installed inside the machine base 7 , and a sliding shaft 24 is installed between the support frames 21 . Specific embodiment 2:
[0030] Reference Figure 1-3 This mechanism uses an ultrasonic sensor 23 to sense the edge of the material, and controls the output servo motor after calculation by the correction main control to achieve real-time correction, ensuring that the material is corrected to the edge in real time during the winding process. The winding shaft uses a frequency conversion control reduction motor to achieve stepless speed regulation. The output torque of the reduction motor shaft is transmitted to the winding air expansion shaft 5 after passing through the magnetic powder clutch, achieving constant torque and stable winding. This winding mechanism can achieve the winding of materials with a thickness of 0.025mm-0.2mm, and achieves the indiscriminate winding of aluminum foil substrates, film substrates, and paper substrates.

In order to more clearly describe the principle of this equipment, its principle is described according to the action position relationship of each workstation in the product production process.
[0031] The first step: insert the core in the shape of a paper tube into the center of the inflatable shaft 5.
[0032] Step 2: One side of the material passes through the middle of the deviation sensor 1 and passes under the rear roller.
[0033] Step 3: Further pull the material head to above the core of the air shaft 5.
[0034] Step 4: Turn on the winding motor 3, which transmits the torque power to the first magnetic powder clutch 4 and one end of the second magnetic powder clutch 19 through the internal sprocket transmission mechanism.
[0035] Step 5: The magnetic powder brake outputs a current of a given tension through the magnetic powder controller to achieve torque changes on the output shaft.
[0036] Step 6: The output end of the magnetic powder clutch transmits the torque to the pneumatic shaft 5 through the central axis of the safety chuck 6, driving the winding core to reel in the material.
[0037] Step 7: Turn on the correction controller, the correction ultrasonic sensor 23 receives the position and gives a signal to the correction controller host, and the host controls the correction servo motor 2 by setting the position.
[0038] Step 8: The deviation correction servo motor 2 realizes precise position correction by moving left and right.
[0039] During the material conveying process, one side will pass through the correction sensor 1, and the correction sensor 1 will receive the position signal and send it to the correction control host. After the host calculates the data PID, it will give the output signal to drive the correction servo motor 2 to realize real-time position correction.
[0040] The main reduction motor is controlled by a frequency converter and is in a constant speed state. The rotational torque is transmitted to the sprocket through the sprocket. The tightness of the sprocket can be adjusted by adjusting the steering wheel 10 of the sprocket. The sprocket is connected to the magnetic powder clutch and the input shaft, so that the speed synchronization and torque synchronization of the sprocket and the input section of the magnetic powder clutch are achieved. The magnetic powder clutch is controlled by a magnetic powder clutch controller, and the torque of the magnetic powder clutch is adjusted to change the output torque of the winding shaft, so that the two winding shafts are in a constant tension and constant speed rotation state. The material is wound on the pneumatic shaft 5. As the winding diameter increases, the required speed decreases, and the required tension also decreases accordingly, so that the same force is achieved from the inner layer to the outer layer.
[0041] In summary:
