The card slots 4 are used to cooperate with the winding roller of the film roll 8. The opposite sides of the frame 1 are fixedly connected with baffles 5 that are covered on the outer side of the turntable 3. The two baffles 5 are An opening structure is provided, and the opening structure can ensure that the roll of the film 8 moves into the inside of the card slot 4, and at the same time ensure that the roll is separated from the card slot 4. A C-shaped unloading rack 6 is fixedly connected to the inner side of the frame 1 and close to the side of the opening structure. A gap is provided between the end of the unloading rack 6 close to the turntable 3 and the turntable 3 to ensure the normal rotation operation of the turntable 3. Two supporting plates 7 are symmetrically fixedly connected to the inner side of the unloading rack 6. The film 8 is rollingly connected to the top of the two supporting plates 7. Both ends of the film 8 are rotatably connected between the card slot 4 and the baffle 5, and a control component for driving the film 8 to move into the card slot 4 is provided on the inner side of the unloading rack 6;

[0024] The film roll 8 to be used is placed on the support plate 7, and the control component pushes the film roll 8 to move toward the side of the turntable 3. When the slot 4 is flush with the discharge rack 6, the film roll 8 can be moved into the slot 4. The rotating shaft 2 drives the turntable 3 to rotate, thereby driving the film roll 8 to move upward to between the baffle 5 and the slot 4, thereby completing the loading of the film roll 8. At the same time, the roller of the film roll 8 after use is moved to the bottom through the rotation of the turntable 3, and can automatically fall down under the action of gravity to complete the unloading work. The overall operation is simple, and the automatic loading of the film roll 8 and the automatic unloading of the roller can be realized. The replacement efficiency of the film roll 8 is higher and the practicability is strong.

[0025] The control component includes a screw rod 9 rotatably connected to the inner side of the unloading rack 6, a guide rod 10 fixedly connected to the inner side of the unloading rack 6 and opposite to the screw rod 9, two movable plates 11, a push plate 12 fixedly connected to the top of the two movable plates 11 and a first motor 13 fixedly connected to the outer side of the unloading rack 6. One end of the screw rod 9 close to the first motor 13 passes through the unloading rack 6 and is fixedly connected to the output shaft of the first motor 13. The operation of the first motor 13 can realize the rotation operation of the screw rod 9. One of the movable plates 11 is threadedly connected to the screw rod 9, and the other is slidably connected to the guide rod 10. When the screw rod 9 rotates, the horizontal movement operation of the movable plate 11 can be realized, so that the moving movable plate 11 can better drive the push plate 12 to move.

By operating the external control device, the operating status of the first motor 13 and the second motor 15 can be better controlled to more conveniently operate the equipment.

[0029] Working principle: Place the roll film 8 to be used on the support plate 7, and the first motor 13 can realize the rotation operation of the screw rod 9 when it is running. When the screw rod 9 rotates, the horizontal movement operation of the movable plate 11 can be realized, so that the movable plate 11 can better drive the push plate 12 to move, and when the push plate 12 moves to the side of the turntable 3, it can push the roll film 8 on the support plate 7 to move into the card slot 4;

[0030] Controlling the operation of the second motor 15 can drive the pulley 14 on the output shaft to rotate, so that the shaft 2 can be better driven to rotate under the transmission action of the belt. The rotating shaft 2 drives the turntable 3 to rotate, thereby driving the roll film 8 to move upward to between the baffle 5 and the slot 4, so as to complete the loading of the roll film 8. At the same time, the roller of the roll film 8 after use is moved to the bottom through the rotation of the turntable 3, and can automatically fall down under the action of gravity to complete the unloading work. The overall operation is simple, and can realize the automatic loading of the roll film 8 and the automatic unloading of the roller. The replacement efficiency of the roll film 8 is higher and the practicability is strong.
