Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1 to 6 : This utility model proposes a vacuum double-sided laminating device for curved surfaces of packaging boxes, comprising: a frame 1; a sliding seat 301 fixed on the upper end face of the frame 1, a base block 302 sliding on the sliding seat 301, a rear hydraulic cylinder 303 fixed on the sliding seat 301, the extended end of the rear hydraulic cylinder 303 fixed on the base block 302; guide rods 304 symmetrically sliding on the base block 302, the lower end of each guide rod 304 fixed on a cover plate 305; a front hydraulic cylinder 307 fixed on the bottom end face of the base block 302, the extended end of the front hydraulic cylinder 307 fixed on the cover plate 305. When sealing the cover plate 305, the front hydraulic cylinder 307 can be extended by driving it; when the front hydraulic cylinder 307 is damaged and cannot extend, the rear hydraulic cylinder 303 can be retracted by driving it, thus realizing emergency locking of the cover plate 305. Compared with existing devices, this device has a flexible structure and good emergency performance.

[0021] The equipment frame 1 has symmetrical support bases 101 fixed at its bottom, which are in contact with the ground. Connecting bases 2 are symmetrically fixed on the equipment frame 1. Each connecting base 2 has a first film roller 201 and a second film roller 202 rotating on it. Each connecting base 2 has a motor 203 fixed on it. The output shaft of the motor 203 is fixed on the first film roller 201 and the second film roller 202. By setting up two first film rollers 201 and two second film rollers 202, double-sided film coating can be achieved with high coating efficiency.

[0022] The equipment frame 1 has a film-coating box 306 fixed on its upper surface. The film-coating box 306 is located directly below the cover plate 305, and a heating element is installed inside the film-coating box 306.

[0023] The inner wall bottom surface of the film-coated box 306 is provided with a pallet 501, on which an arc-shaped packaging box 4 is placed. The equipment frame 1 is symmetrically fixed with unloading hydraulic cylinders 5, and the extended ends of the unloading hydraulic cylinders 5 are all fixed on the pallet 501. During unloading, the two unloading hydraulic cylinders 5 are driven to extend, and the two unloading hydraulic cylinders 5 drive the pallet 501 to move upward to lift the arc-shaped packaging box 4, which facilitates the unloading of the arc-shaped packaging box 4 after film coating.

[0024] The top surface of the film-coating box 306 is provided with a U-shaped groove 308. The bottom surface of the upper half of the cover plate 305 is welded with a U-shaped sealing block 309. The sealing block 309 is aligned with the U-shaped groove 308 and matches it. After the cover plate 305 completes the sealing of the film-coating box 306, the sealing block 309 and the U-shaped groove 308 are in an inserted sealing state. The sliding seat 301, base block 302, rear hydraulic cylinder 303, guide rod 304, cover plate 305, film-coating box 306, front hydraulic cylinder 307, U-shaped groove 308 and sealing block 309 together form the film-coating mechanism 3. By inserting the sealing block 309 into the U-shaped groove 308, the sealing performance between the cover plate 305 and the film-coating box 306 can be improved again.

[0025] Example 2, based on Example 1, such as Figures 1 to 6 As shown, the cover plate 305 has a stepped structure. The outer wall of the lower half of the cover plate 305 contacts the inner wall of the coating box 306, and the bottom surface of the upper half of the cover plate 305 contacts the top surface of the coating box 306. A vacuum pump 6 is fixed on the equipment frame 1 and connected to the coating box 306. The stepped structure of the cover plate 305 can improve the sealing performance between the cover plate 305 and the coating box 306 and prevent air leakage during vacuuming.

[0026] The working principle of this embodiment: When using this equipment to laminate the arc-shaped packaging box 4, firstly, start the motor 203 on the connecting seat 2. The motor 203 drives the first film roller 201 and the second film roller 202 to rotate, adjust the film position, and place the arc-shaped packaging box 4 on the tray 501 inside the laminating box 306. At this time, it is necessary to ensure that the bottom of the arc-shaped packaging box 4 is in contact with the lower film. During the lamination process, the laminating mechanism 3 needs to be operated to complete the sealing: the front hydraulic cylinder 307 on the drive base 302 extends, driving the cover plate 305 below the guide rod 304 to move down. The lower half of the outer wall of the cover plate 305 contacts the inner wall of the laminating box 306, and the bottom surface of the upper half contacts the top surface of the laminating box 306. At the same time, the sealing block 30 on the cover plate 305... 9 is inserted into the U-shaped groove 308 on the top surface of the laminating box 306 to form a double seal; then the vacuum pump 6 is started to evacuate the laminating box 306, and the heating element inside the laminating box 306 is started at the same time. The cooperation between the stepped cover plate 305 and the sealing block 309 and the U-shaped groove 308 can effectively prevent air leakage; if the front hydraulic cylinder 307 is damaged and cannot extend, the rear hydraulic cylinder 303 on the sliding seat 301 can be driven to retract, driving the base block 302 to slide, indirectly realizing the emergency locking of the cover plate 305; after the laminating is completed, when unloading is required, the two unloading hydraulic cylinders 5 on the drive equipment frame 1 are extended, and the unloading hydraulic cylinders 5 drive the pallet 501 to move upward, lifting the arc-shaped packaging box 4 out of the laminating box 306 to complete the unloading operation.
