The above at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

One, when the present invention carries out trimming operation to polyimide film, at first it is taken off by turning the rotary cover on the release bar, at this moment, then the polyimide film of whole roll needs to be sleeved on Put it on the release rod, and then rotate the rotating cover to the release rod, and then set the rewinding roller on the rewinding rod in the same way, and then drive the drive shaft on the output end of the drive motor through the operation of the drive motor. The corresponding drive frame rotates, the drive shaft rotates to drive the drive helical gear to rotate, and the drive helical gear rotates to drive the transmission helical gear to rotate, thereby driving the release rod to rotate on the fixed frame, and the rotation of the release rod drives the entire roll on the release rod The polyimide film rotates, so that the head end of the whole roll of polyimide film is placed out of the relative length, so that the head end is set on the rotating drum. At this time, the product is removed by the corresponding trimming equipment When the length of trimming is enough to set the head end on the winding rod, the preliminary operation of the whole roll of polyimide film is completed, and the helical gear is driven synchronously by the rotation of the drive shaft. Rotate, turn the helical gear to drive the adjustment helical gear to rotate, thereby driving the winding rod to rotate to carry out the winding operation on the finished product after trimming. At this time, the release rod and the winding rod are in the opposite direction of rotation and synchronous rotation. Therefore, the polyimide film released by the unwinding rod and the polyimide film wound up by the winding rod are at the same length, so that the polyimide film is always in the state of precise trimming during the operation process, Because the length is too long or too short, it will not loosen, wrinkle or collapse, thereby improving the processing quality of the product.

Its two, when the present invention trimming operation of polyimide film, because the thickness of the polyimide film of whole volume is different with the kind, at this moment by regulating the adjustment plate on the hydraulic cylinder output end driven by the operation of the hydraulic cylinder, upwards or The downward movement drives the adjustment frame, the adjustment column, the adjustment helical gear, the rotating helical gear and the take-up rod to move upward or downward on the adjustment plate, so as to adjust the distance between the take-up rod and the release rod to realize Suitable for rolls of polyimide films of different thicknesses and types.

Its three, when the first end of the polyimide film of the whole roll is set on the rotating drum in the present invention, firstly, the distance control gear on the output end of the distance control motor is driven to rotate by the operation of the distance control motor, and the rotation of the distance control gear drives two The distance controls the rack to move outward symmetrically, thus driving the two edge trimming equipment to move outward symmetrically, and synchronously also drives the two limit devices to move outward, so that when the personnel set the head end on the rotating sleeve, they will not It will cause obstruction and contact with the equipment to cause injury, and it is also convenient for personnel to carry out the sleeve operation. When the head end is sleeved on the rotating drum, the motor will move again through the connection distance control to drive the two trimming equipment to move symmetrically inward.
