[0017] Advantages:

[0018] 1) The present application discloses a laminating machine, which is improved by the winding and switching unit. When the winding of the base material on the film roll is completed and the new film roll needs to be switched for continuous winding, the angle can be directly set to make the shaft roller rotating disc rotate by a certain angle, so that the winding roller with full base material rotates downward, and the winding roller with new film roll rotates to the top. When the winding roller rotates to the top, the gap exists at the top of the annular magnet, so that the magnetic force does not exist between the permanent magnet connected to the inner end of the winding roller and the annular magnet. The shaft moving rod moves along the axis in the hollow roller body under the action of the first spring. In the process of the shaft moving rod moving axially, the telescopic key block is pushed out from the key hole by the action of the circular truncated cone block, and the film roll is tightly fixed by the expansion sheet at the outer end of the telescopic key block, so that it can rotate synchronously with the winding roller. Conversely, the telescopic key block is recovered inward due to the magnetic force between the permanent magnet and the annular magnet, so that the entire winding can be quickly taken out from the winding roller. The winding and switching unit has novel structure, which not only realizes the quick switching of the base material winding during the winding process of the laminating machine, but also automatically tightens and fixes the film roll and quickly unloads the full winding, realizes the high-speed automatic operation of the entire laminating machine, and has excellent use effect.

[0019] 2) The present application further designs the winding and switching unit, and the cutting device is arranged to cut the base material during the switching process. The cutting device can quickly cut the base material without affecting the quality of the base material by using the spring instantaneous pullback effect to make the blade pass through the surface of the base material. In addition, the pressure roller can be rotated around the outer surface of the top film roll by the action of the third motor after the base material is cut, so that the cut part of the base material is wound on the outer surface of the film roll to connect them, and then the top winding roller can be directly started for winding. The above design realizes the automatic cutting and automatic splicing of the base material after cutting on the new film roll for winding and laminating, realizes the uninterrupted and efficient continuous action of the entire laminating machine, and improves the processing efficiency of the laminating machine.
