Referring to Fig. 1, there is a gap between the pressure roller 7 and the winding shaft, and the pressure roller 7 automatically adjusts the gap between the pressure roller 7 and the winding diameter through an actuator. In front of the winding core, there is a pressure roller 7 that can change its position. Its main function is to press the film against the winding core to implement contact winding or small gap winding, so that the flat film Quickly turn to the winding core to achieve the purpose of smooth winding. At the same time, apply a certain pressure on the winding shaft with the help of the pressure roller 7 to timely remove the air between the film layers during winding, so that the parent roll does not become loose. Generally, the air content in the parent roll can be reduced to 12% to 18% after the pressure roller 7 is used.

The working principle of this embodiment: when the film is rolled up, the film is first flattened by the flattening roller 1 to eliminate some longitudinal wrinkles produced by the film under the action of tensile stress, and then the tension generated on the film surface is tightened by the tension swing roller 2. Then the film is directly pressed on the cutter roller 3. The surface of the cutter roller 3 is made of special material, which is super hard and wear-resistant. After the film is cut into the required width, the film enters the traction roller 4. Enter the film storage roller 5, and then the film enters the tension roller 6. When the film surface tension is constant, the film is wound into the winding shaft through the pressing roller 7 and the wrapping roller 8. The winding machine can automatically measure the length. When the set value is reached, the finished roll is pressed by the pressure roller 7, the winding shaft stops rotating, the second cylinder 19 drives the swing rod 17 to move, and the cutter 9 is pressed against the film surface, and then the cutter 9 is driven by the rodless cylinder 18. The film is cut horizontally, and then the second cylinder 19 drives the swing rod 17 to move away from the film surface, so that the cutter 9 is far away from the film surface. The spool 20 is rotated out, and the second winding shaft 21 enters the winding position. After changing the roll, the wrapping roller 8 presses the film on the second winding shaft 21, so that it can be rolled in smoothly without slipping, and continues to roll.

The working principle of the roll change in this embodiment: when the roll is changed and cut off, the rewinding shaft at the back stops rotating, while the front roll continues to operate. Under the condition of ensuring the film surface tension, the film storage roller 5 starts to work, and the film storage roller 5 starts to work. Driven by the first cylinder 13, the excess film is rolled down the linear guide rail 14 to the film storage roller 5. After the roll change is completed, the film storage roller 5 returns to the high position, and the film storage device stops working, ensuring that the film surface tension is not changed. The quality of winding is mainly guaranteed by the tension of the film surface due to the influence of the stop of the reel at the time of rolling. The work of the film storage device can avoid the change of the film surface tension during the roll change and ensure the continuity of the roll change action.

This specific embodiment is only an explanation of the utility model, and it is not a limitation of the utility model. After reading this description, those skilled in the art can make modifications to the embodiment without creative contribution according to needs, but as long as it is within the utility model All new claims are protected by patent law.
