[0012] Through the above technical solution, the top block in the mounting column is controlled to squeeze the second circular plate, thereby controlling the force between the two circular plates squeezing the aluminum film roll, thereby preventing the aluminum film roll from rotating naturally due to inertia during the unwinding process.

[0013] Furthermore, the other end of the screw is fixedly connected to a screw block, a screw piece is detachably mounted on the surface of the screw block, a slot is provided on the surface of the screw block, and the size of the slot is adapted to the size of the screw piece.

[0014] The above technical solution makes it easier for workers to control the rotation of the screw.

[0015] Furthermore, a rubber sheet is fixedly connected to the surface of the top block.

[0016] Through the above technical solution, the friction force of the top block against the second circular plate is increased, so that the top block is more stably pressed against the second circular plate.

[0017] Furthermore, the winding device includes a first circular plate, which is fixedly connected to the transmission shaft. The arc surface of the transmission shaft is slidably connected to the second circular plate, and the surface of the transmission shaft is fixedly connected to a fixed block.

[0020] Through the above technical solution, the second circular plate is always in contact with the top block.

[0021] The above solution of the utility model includes at least the following beneficial effects:

[0022] The utility model provides an extrusion device. When the tension of the unwinding roller needs to be adjusted, the screw in the fixed plate is rotated to control the top block in the mounting column to squeeze the second circular plate, thereby controlling the force of squeezing the aluminum film roll between the two circular plates, thereby avoiding the natural rotation of the aluminum film roll due to inertia during the unwinding process.

When the hot stamping operation is performed, the dedicated equipment winds the aluminum film between the first circular plate 31 and the second circular plate 32 on the transmission shaft 1. After the aluminum film roll 2 is wound on the transmission shaft 1, the screw 402 moves, thereby driving the top block 405 in the mounting column 404 to press against the second circular plate 32, and applying pressure to the aluminum film roll 2 between the first circular plate 31 and the second circular plate 32. As the screw 402 drives the top block 405 to press against the second circular plate 32, the second circular plate 32 will move, and then the transmission shaft 1 is installed on the hot stamping machine. As the equipment is started, the transmission shaft 1 is driven to rotate, thereby The aluminum film roll 2 between the first circular plate 31 and the second circular plate 32 on the transmission shaft 1 is retracted and released, and the second circular plate 32 will squeeze the aluminum film roll 2, so that the aluminum film roll 2 will not rotate naturally due to inertia when it is naturally unwound, so that the aluminum film roll 2 is unwound smoothly during the unwinding process, effectively ensuring the stability of the hot stamping operation. The winding roller needs to be maintained and serviced after long-term use.

As the screw 402 drives the top block 405 to press against the second circular plate 32 , the second circular plate 32 will move, so that the spring 33 will expand and contract with the movement of the second circular plate 32, and then the drive shaft 1 will be installed on the hot stamping machine. As the equipment starts, the drive shaft 1 will rotate, thereby retracting and releasing the aluminum film roll 2 between the first circular plate 31 and the second circular plate 32 on the drive shaft 1. The second circular plate 32 will squeeze the aluminum film roll 2, so that the aluminum film roll 2 will not rotate naturally due to inertia when it is naturally unwound, so that the aluminum film roll 2 is unwound smoothly during the unwinding process, effectively ensuring the stability of the hot stamping operation.
