[0002] Laser film generally adopts computer dot lithography technology, 3D true color holographic technology, multiple and dynamic imaging technology, etc. From the perspective of product composition, laser film products can be roughly divided into three types: OPP laser film, PET laser film and PVC laser film. Laser packaging is a sub-industry in the packaging industry and has achieved rapid development. Compared with other products in the packaging industry, laser packaging materials not only have novel and bright appearance effects, but also have high-tech anti-counterfeiting functions. They are known as the most cutting-edge technical products in the world's packaging and printing industry. The application fields of laser materials are already very wide, and they have been rapidly promoted in industries such as food, medicine, daily chemicals, tobacco and alcohol, clothing, gift packaging, and decorative materials.

[0022] Reference Figure 1-4 , an embodiment of the utility model is proposed, a cutting device for laser film production, comprising a device table 1 and two propulsion mechanisms;

[0023] The two propulsion mechanisms are respectively arranged on the two side surfaces of the middle part of the device table 1. A horizontal frame 15 is vertically fixedly connected to the upper surface of the device table 1 and located at the rear of the two propulsion mechanisms. A plurality of first electrically-controlled telescopic rods 16 are vertically fixedly connected to the top of the horizontal frame 15. A cutting knife 17 adapted to the width of the device table 1 is laterally fixedly connected to the bottom ends of the plurality of first electrically-controlled telescopic rods 16.

[0024] In the device, the rolled laser film is transported by the propulsion mechanism arranged on both sides of the device table 1. After the strip-shaped laser film is transported to the rear end of the cutting knife 17, multiple first electrically controlled telescopic rods 16 are controlled to extend synchronously to drive the cutting knife 17 to descend and cut the laser film.

[0025] Furthermore, second electrically-controlled telescopic rods 18 are vertically fixedly connected to the surfaces on both sides of the rear end of the device table 1, a horizontal plate 19 is horizontally fixedly connected between the top ends of the two second electrically-controlled telescopic rods 18, through grooves are vertically penetrated at both ends of the upper surface of the horizontal plate 19, and slide rods 20 are vertically slidably connected inside the two through grooves, and mounting seats 22 are fixedly connected to the bottom ends of the two slide rods 20, springs 21 are vertically fixedly connected between the top ends of the two mounting seats 22 and the lower surface of the horizontal plate 19, mounting plates 23 are fixedly connected to the surfaces on the opposite sides of the two mounting seats 22, and a pressure roller structure is arranged between the two mounting plates 23.

[0026] Before cutting the laser film, the two second electrically-controlled telescopic rods 18 will contract to drive the horizontal plate 19 to descend, thereby synchronously driving the two mounting seats 22 to descend. The pressure roller structure arranged between the two mounting seats 22 can press one end of the laser film tightly, so that the laser film remains taut to ensure the cutting effect. Multiple springs 21 can ensure that the pressure roller structure can always be close to the surface of the laser film.

[0027] Furthermore, the pressure roller structure includes a first rotating shaft 24 and a second rotating shaft 25 which are respectively connected to the surfaces of opposite sides of the two mounting plates 23 for transverse rotation. The outer surface of the first rotating shaft 24 is fixedly connected to a roller 26 along its length direction. The other end of the first rotating shaft 24 is fixedly connected to a first disc 27. The other end of the second rotating shaft 25 is fixedly connected to a second disc 28.

[0029] A damping structure is formed between the first disc 27 and the second disc 28 in the pressure roller structure under the action of multiple inner blades 29 and the liquid medium, which can drive the roller 26 to rotate when the roller 26 is not subjected to force. When the roller 26 contacts the laser film, the friction force will not force the laser film to continue to move toward the rear of the device. When the laser film is cut, the roller 26 will quickly resume rotation and drive the cut part to continue to move toward the rear of the device table. No manual collection operation is required. Moreover, under the action of the first disc 27 and the second disc 28, the motor 30 in the structure can also remain in operation all the time without repeated start and stop, thereby improving the practicality of the device.

[0030] Furthermore, the structures of the two propulsion mechanisms are the same, one of the propulsion mechanisms includes a mounting plate 2 fixedly connected to one side of the upper surface of the device table 1 along the length direction, and the upper and lower parts of the side surface of the mounting plate 2 are respectively and horizontally penetrated with a plurality of upper shaft holes and lower shaft holes at intervals along the length direction, and the interiors of the plurality of upper shaft holes and the plurality of lower shaft holes are respectively and horizontally rotatably connected with upper rotating shafts 3 and lower rotating shafts 4, and the surfaces of the plurality of upper rotating shafts 3 and the plurality of lower rotating shafts 4 located on the inner side of the mounting plate 2 are respectively fixedly connected with upper propulsion wheels 5 and lower propulsion wheels 6, and the plurality of upper propulsion wheels 5 and the plurality of lower propulsion wheels 6 correspond to each other, and the surfaces of the plurality of upper rotating shafts 3 and the plurality of lower rotating shafts 4 located on the outer side of the mounting plate 2 are respectively fixedly connected with upper sprocket wheels 7 and lower sprocket wheels 9, and the plurality of upper sprocket wheels 7 are connected by a first chain 8 for transmission, and the plurality of lower sprocket wheels 9 are connected by a second chain 10 for transmission.

[0031] The outer surfaces of the front-end upper rotating shaft 3 and the lower rotating shaft 4 are respectively located on the outer sides of the upper sprocket 7 and the lower sprocket 9, and are fixedly connected with gears 11. The two gears 11 are meshed with each other. The outer surface of the device table 1 is fixedly connected with a mounting frame 12.

The outer surface of the mounting frame 12 is laterally fixedly connected with a motor 13, and the output shaft of the motor 13 is fixedly connected to one side surface of the half gear 14.

[0032] After the motor 13 is started, when its output shaft rotates, the half gear 14 on the surface of the output shaft will drive one gear 11 to rotate, and the other gear 11 will synchronously rotate in the opposite direction, and the multiple upper rotating shafts 3 and the multiple lower rotating shafts 4 are respectively driven by the first chain 8 and the second chain 10 to rotate synchronously, so that the upper rotating shafts 3 and the lower rotating shafts 4 in the upper and lower rows move synchronously in opposite directions, thereby driving the movement of the laser film. Under the action of the half gear 14, the upper propulsion wheel 5 and the lower propulsion wheel 6 in the propulsion mechanism will rotate intermittently. During the period of stopping rotation, the cutting operation can be performed by the cutting knife 17 to ensure the smooth operation of the device.

[0035] During operation, before cutting the laser film, the two second electrically-controlled telescopic rods 18 will contract to drive the horizontal plate 19 to descend, thereby synchronously driving the two mounting seats 22 to descend. The pressure roller structure arranged between the two mounting seats 22 can press one end of the laser film tightly, so that the laser film remains in a taut state to ensure the cutting effect. The multiple springs 21 can ensure that the pressure roller structure can always be closely attached to the surface of the laser film. A damping structure is formed between the first disc 27 and the second disc 28 in the pressure roller structure under the action of the multiple inner blades 29 and the liquid medium. , when the roller 26 is not subjected to force, it can drive the roller 26 to rotate, and when the roller 26 contacts the laser film, the friction force will not force the laser film to continue to move to the rear of the device. When the laser film is cut, the roller 26 will quickly resume rotation and drive the cut part to continue to move to the rear of the device table. No manual collection operation is required, and under the action of the first disc 27 and the second disc 28, the motor 30 in the structure can also keep running all the time without repeated starting and stopping, thereby improving the practicality of the device.
