The output end of the second motor 54 is connected to the gear 55 through a coupling. The gear 55 is meshed with the toothed plate 51 to realize the reciprocating movement of the film changing table 2 on the machine base 1. The film used by the film cutting and gold marking machine reciprocates on the film changing table 2, which is convenient for the rapid fixation and separation of the film used by the film cutting and gold marking machine on the film changing table 2, making it convenient to replace and disassemble the film on the film changing table 2 with low loss. The film guiding mechanism 3 is used for the limited introduction of the film changing on the film changing table 2, making the film changing fast and accurate, and combined with the film changing fixation, making the film changing operation simple.

[0024] Specifically, a film scratching and gold-spraying machine is provided on the top of the machine base 1 on one side of the film changing table 2. The film changing table 2 extends out of the machine base 1 on one side away from the film scratching and gold-spraying machine.

The adjustment seat 53 can adjust the position of the No. 2 motor 54 and the gear 55 on the movable frame 52, so that the gear 55 on the movable frame 52 can maintain an adaptive meshing state with the tooth plate 51 in the guide rail groove 5.

[0025] Furthermore, limit sliders 56 are provided on two opposite sides of the bottom of the movable frame 52, and limit sliders 57 are provided on the top of the machine base 1 on two opposite sides of the guide groove 5. The limit sliders 56 are slidably arranged inside the limit sliders 57, and the limit sliders 56 at the bottom of the film changing table 2 slide in the limit sliders 57 on the top of the machine base 1.

[0026] Furthermore, the fixing mechanism includes a fixing plate 4, a fixing hole 41, a vacuum generator 42 and a connecting pipe 43. The top of the film changing table 2 is provided with a fixing plate 4 through a mounting groove. The fixing plate 4 is arranged in a hollow structure.

The vacuum generator 42 is arranged on the film changing table 2 away from the side of the film scratching and gold-spraying machine. Under the action of the vacuum generator 42, a negative pressure state is formed inside the fixing plate 4 through the connecting pipe 43. The fixing hole 41 on the fixing plate 4 is used to negatively adsorb and fix the film for the film scratching and gold-spraying machine on the film changing table 2. After the film scratching is completed, the vacuum adsorption and fixation is stopped.

[0027] Furthermore, a plurality of fixing plates 4 and vacuum generators 42 are provided one-to-one, a plurality of fixing holes 41 are evenly distributed on the fixing plates 4, and the fixing plates 4 are evenly spaced on the membrane changing table 2, that is, the membrane changing table 2 fixes the membrane in a plurality of units, and the fixation is balanced.

[0028] Furthermore, the top of the fixed plate 4 is arranged at the same plane height as the top of the membrane changing table 2, so that the membrane is placed flat on the fixed plate 4 and the membrane changing table 2, the bottom of the membrane changing table 2 is arranged in contact with the top of the machine base 1, and the membrane changing table 2 moves on the machine base 1 in a compact structure.

[0029] The method of using this embodiment is as follows: the film for the film cutting and gold-spraying machine is introduced to the top of the film changing table 2 through the film guiding mechanism 3, and under the action of the vacuum generator 42, a negative pressure state is formed inside the fixed plate 4 through the connecting pipe 43, and the film for the film cutting and gold-spraying machine on the film changing table 2 is fixed by negative pressure adsorption using the fixing hole 41 on the fixing plate 4, and the second motor 54 on the moving frame 52 drives the gear 55 to rotate, and the gear 55 is meshed with the toothed plate 51 in the guide groove 5, so that the gear 55 rotates to drive the moving frame 52 to move in the guide groove 5, At the same time, the limiting slider 56 at the bottom of the film changing table 2 slides within the limiting slide groove 57 on the top of the machine base 1 to realize the reciprocating movement of the film changing table 2 on the machine base 1, and the film used by the film cutting and gold labeling machine reciprocates with the film changing table 2. After the film cutting is completed, the vacuum adsorption and fixation are stopped, which is convenient for the rapid fixation and separation of the film used by the film cutting and gold labeling machine on the film changing table 2, so that the film can be easily disassembled and replaced on the film changing table 2 with low loss. The film guiding mechanism 3 is used for the limited introduction of the film changing on the film changing table 2, so that the film changing is fast and accurate, and combined with the film changing fixation, the film changing operation is simple.

The No. 1 motor 35 drives the bidirectional screw 32 in the adjusting groove 31 to rotate. The two threaded blocks 33 provided on the bidirectional screw 32 drive the two film guide plates 34 to move closer or farther on one side of the film changing table 2, so that the spacing between the two film guide plates 34 is adapted to the film changing width, so that the film used for the film scratching and gold label spraying machine can be limited between the two film guide plates 34 and introduced onto the film changing table 2, and the application range is wide.
