[0002] Glass fiber cloth is one of the raw materials for producing copper clad laminates, and its unwinding is at the front end of the process. In the later stage of unwinding the glass fiber cloth coil, since the bending radius of the glass fiber cloth on the raw material reel becomes smaller and smaller, the unwound glass fiber cloth will still warp after being stretched by the lifting roller group and the fixed roller group, resulting in poor bonding with other materials and insufficient flatness in subsequent processing. In addition, the lifting roller group needs to be raised to the top in the later stage of unwinding to store the glass fiber cloth. When the glass fiber cloth coil is replaced at the front end, there is sufficient reserve in the device to ensure continuous production. In this way, the length of each section of the glass fiber cloth between the lifting roller group and the fixed roller group will cause the glass fiber cloth to warp, aggravating the problem of the flatness of the glass fiber cloth.

The glass fiber cloth 19 revolves back and forth between the rollers 14 of the lifting roller group and the fixed roller group. The greater the distance between the lifting roller group and the fixed roller group, the longer the storage length of the glass fiber cloth 19. After the lifting roller group rises to the top, the pulling mechanism is inserted from the side. On the one hand, it can pull the glass fiber cloth 19 laterally so that the glass fiber cloth 19 can be fully stretched to prevent it from being easily warped during subsequent processing due to being wound for a long time under the small bending radius of the rolled raw material reel, ensuring that it is easier to fit with other materials and has better flatness during subsequent processing. On the other hand, it can further increase the storage length of the glass fiber cloth 19.
[0019] In the above embodiment, the pulling mechanism includes a transverse cylinder 12, a skateboard 10, a pulling motor 16, a pulling gear 17 and two pulling roller groups.

The pulling roller group consists of a pulling roller plate 13 and a roller 14 rotatably connected to its front end.

[0021] Description of the working method of this utility model:
[0022] The glass fiber cloth 19 roll is unwound, and the glass fiber cloth 19 is passed between the lifting roller group and the fixed roller group and is pulled by an external power device; in the early stage of unwinding the glass fiber cloth 19 roll, the lifting roller group is close to the fixed roller group. At this time, the storage of the glass fiber cloth 19 is the least, and the glass fiber cloth 19 quickly passes back and forth between the lifting roller group and the fixed roller group to be fully stretched and straightened; in the late stage of unwinding the glass fiber cloth 19 roll, since the bending radius of the glass fiber cloth 19 on the raw material reel becomes smaller and smaller, the unwound glass fiber cloth 19 passes through the lifting roller group. After the stretching of the wheel group and the fixed roller group, there will still be warping, which will lead to poor bonding effect with other materials and insufficient flatness in subsequent processing. In the late stage of unwinding, the lifting roller group needs to be raised to the top to store the glass fiber cloth 19. When the glass fiber cloth 19 roll is replaced at the front end, there is sufficient reserve in the device to ensure continuous production. In this way, the length of each section of the glass fiber cloth 19 between the lifting roller group and the fixed roller group will cause the glass fiber cloth 19 to warp, aggravating the problem of the flatness of the glass fiber cloth 19. At this time, the pulling roller group intervenes to adjust the glass fiber cloth 19. The problem of the glass fiber cloth 19 is improved; the transverse cylinder 12 pushes the slide plate 10 to the bottom of the fixed roller group, so that the pulling roller group enters between the lifting roller group and the fixed roller group, and the rollers 14 on the pulling roller group are inserted into between the glass fiber cloth 19. Under the rotation of the pulling motor 16, the rollers 14 on the two pulling roller groups respectively press against the glass fiber cloth 19 and pull in opposite directions. On the one hand, each section of the glass fiber cloth 19 between the lifting roller group and the fixed roller group can be subdivided into three sections for stretching to ensure the flatness in subsequent processing. On the other hand, the total storage length of the glass fiber cloth 19 can be increased. The speed is increased to buy more time for replacing the glass fiber cloth 19 roll; after the front end of the new glass fiber cloth 19 is successfully fused with the end of the old glass fiber cloth 19, the replacement of the glass fiber cloth 19 roll is completed, and then the traction speed of the external power device is accelerated, and the two pulling roller groups gradually move toward the middle and loosen the glass fiber cloth 19, and then the transverse cylinder 12 pulls the slide 10 to withdraw the pulling roller group from between the glass fiber cloths 19, and finally the lifting roller group slowly descends and gradually approaches the fixed roller group until the glass fiber cloth 19 quickly moves back and forth between the lifting roller group and the fixed roller group in the initial state.
[0023] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
