Compared with the prior art, the PI film winding device can be used for adjusting according to whether the PI film is tensioned or loosened in the PI film winding process, automatically adjusting and controlling the tension of the PI film, and triggering the alarm 502 to operate when excessive abnormality occurs in the tension.
The working process and principle related to the whole content of the embodiment are as follows:
when a worker needs to wind the PI film by using the winding machine body 1, the PI film is wound on the winding machine body 1 according to a path, then connected with the winding roller 2, and then drives the winding roller 2 to rotate, the PI film is wound, before the worker drives the winding roller 2 to rotate and wind the PI film, the knob 318 is rotated, the threaded rod 317 is driven to rotate on the winding machine body 1, the threaded rod 317 is in threaded connection with the connecting frame 316 through the threaded rod 317 and the connecting frame 316, and the connecting frame 316 is vertically and slidingly connected to the winding machine body 1, so that the connecting frame 316 can be driven to move upwards on the winding machine body 1, and the sliding rails 305 connected to the two sides of the connecting frame 316 are driven to synchronously rise, and the rising distance of the sliding rails 305 is increased, so that the adaptive plate 301 rises to a designated height, the lifting rod 304 can be driven to push the fixed plate 313 to rise, and the rising height of the adaptive plate 301 is dependent on the thickness of the PI film wound on the outer surface of the winding roller 2, therefore, the quantity of the PI film wound on the outer surface of the winding roller 2 can be controlled according to the requirement of the worker, the PI film is not only satisfied, the rolling quantity of the PI film in the winding process is ensured, the requirement of different PI film or the rolling order is not satisfied, the excessive rolling cost is avoided, the rolling efficiency is not guaranteed, and the excessive rolling film utilization is guaranteed, and the rolling cost is guaranteed, and the film is not required to be changed in the winding process;
in the process that the PI film is wound on the outer surface of the winding roller 2, the diameter of the winding roller 2 is gradually increased, and as the PI film wound on the outer surface of the winding roller 2 is increased, the adaptive plate 301 arranged above the winding roller 2 can be pushed to slide upwards in the winding machine body 1 through the arranged lifting block 302, and moreover, the contact between the adaptive plate 301 and the PI film can smooth the PI film wound on the outer surface of the winding roller 2, so that the PI film is prevented from being wrinkled in the winding and winding process;
along with the lifting of the PI film wound on the outer surface of the wind-up roll 2 to the adapting plate 301, the adapting plate 301 can drive the lifting rod 304 connected with the rear side to synchronously lift, the lifting rod 304 is driven to contact with the fixing plate 313 above, the fixing plate 313 pushes the clamping block 312 to slide upwards on the sliding rail 305, the clamping block 312 slides out of the sliding block 306 slidingly connected with the inside of the sliding rail 305, when the clamping block 312 and the sliding block 306 are completely separated, the resistance force born by the sliding block 306 disappears, at the moment, the state of the first spring 308 is in a stretching state, the sliding block 306 is automatically pulled to slide from the front side to the rear side inside the sliding rail 305 by the pulling force of the first spring 308, the pushing rod 307 is pushed to slide out from the inside of the sliding rail 305, one end of the expansion plate 309 can be driven to synchronously move horizontally in the horizontal movement process of the sliding block 306, the expansion plate 309 is driven to move from an inclined state to a vertical state, the expansion plate 309 is contracted along with the change of the state of the expansion plate 309, when the expansion plate 309 cannot continue to contract, the expansion plate 309 can synchronously push the connecting blocks 310 to move downwards, so that the cutting knife 303 connected between the connecting blocks 310 vertically descends, the connection between the PI film below and the winding roller 2 is cut, the quantity of the PI film wound on the outer surface of the winding roller 2 can be controlled, the consistency of the quantity and the quality of the PI film wound each time can be ensured, the product quality problem caused by inconsistent winding quantity is reduced, the manual intervention is reduced, the labor burden of workers is reduced, and the problem caused by manual operation errors in the winding process of the PI film is avoided;
in the process that the connecting block 310 drives the cutting knife 303 to descend, the connecting block 310 can drive one end of the connecting plate 401 to synchronously descend, the connecting plate 401 is driven to move horizontally from an inclined state, the moving plate 402 rotationally connected with the other end of the connecting plate 401 is pushed to horizontally slide from the rear side to the front side on the inner wall of the winding machine body 1, the stop plate 403 connected with the moving plate 402 is in contact with the winding roller 2, the rotation of the winding roller 2 is stopped, the condition that a PI film wound on the outer surface falls off due to continuous rotation of the winding roller 2 is avoided, the integrity of the PI film is protected, and the risk that the PI film falls off in the winding process is reduced;
when the PI film is wound on the winding machine body 1 according to the path, the PI film passes through the lower parts of the tension rollers 501 in sequence, in the winding process of the PI film by the winding roller 2, if the tension force of the PI film is relaxed, the tension rollers 501 are influenced by the balancing weights 503 at the two sides and are in sliding connection with the vertical grooves 6 through the moving blocks 504, the tension rollers 501 are driven to automatically descend, the PI film is pressed down, the tension force of the PI film in the winding process is kept, when the tension force of the PI film is excessive, the PI film pulls the tension rollers 501 to move upwards and drives the moving blocks 504 at the two sides to ascend in the vertical grooves 6, and when the moving blocks 504 ascend or descend in the vertical grooves 6 and can not slide continuously, the moving blocks 504 can contact the buttons 505 which are connected up and down symmetrically, so that the alarm 502 connected with the upper end surface of the winding machine body 1 is opened to operate, the problems of uneven curling, wrinkling or misplacement of the PI film in the winding process are avoided, the PI film winding uniformity is improved, and the reliability of the PI film in the winding process can be guaranteed in time by workers;
when the winding roll 2 winds the PI film, a worker needs to push the push rod 307 to drive the sliding block 306 to slide from the rear side to the front side in the sliding rail 305, and pulls the first spring 308, along with the movement of the sliding block 306, the sliding block 306 gradually contacts the clamping block 312, in the process that the sliding block 306 contacts the clamping block 312, the inclined surface above the front side of the sliding block 306 contacts the cambered surface below the rear side of the clamping block 312, the clamping block 312 is extruded to slide out from the sliding rail 305, the cambered surface of the clamping block 312 slides along the inclined surface of the sliding block 306, the second spring 315 connected with the upper end surface of the clamping block 312 is extruded, and when the clamping block 312 slides out from the sliding rail 305 and moves to the uppermost side of the clamping block 312, the clamping block 312 can be automatically pushed to slide into the sliding block 306 by the rebound force of the second spring 315, and the clamping block 306 is clamped with the position of the clamping block 312 in the sliding rail 305, so that the quantity of the PI film wound on the outer surface of the winding roll 2 is controlled later.
