When working, the material roll is sequentially arranged to pass through the first guide roller 2, the third guide roller 4, the second guide roller 3 and the die cutting assembly on one side, and then sequentially pass through the second guide roller 3, the third guide roller 4 and the first guide roller 2 on the other side, and finally pass out.

[0028] Specifically, a slide rail 5 is correspondingly arranged in the middle of the inner side of the two installation wall plates 1, a sliding seat 11 is slidingly arranged on the slide rail 5, and the two mounting seats 10 are correspondingly arranged on the two sliding seats 11; a transmission roller shaft 6 is correspondingly rotatably arranged below the two first guide rollers 2, a synchronous pulley 7 is correspondingly arranged at the two ends of the transmission roller shaft 6, a synchronous belt 8 is correspondingly arranged between the synchronous pulleys 7 at the same end of the two transmission roller shafts 6, and the two mounting seats 10 are correspondingly connected with the upper half of the two synchronous belts 8.

[0029] A mounting block 12 is correspondingly arranged in the middle of the mounting seat 10, a mounting toothed plate 13 is correspondingly arranged below the mounting block 12, the bottom of the mounting block 12 is correspondingly attached to the top of the upper half of the synchronous belt 8, the mounting toothed plate 13 is correspondingly attached to the bottom of the upper half of the synchronous belt 8, the mounting toothed plate 13 passes through the synchronous belt 8 through a screw and is correspondingly arranged at the bottom of the mounting block 12, so that the mounting block 12 is mounted and fixed to the upper half of the synchronous belt 8, so that the movement of the mounting seat 10 can be driven by the transmission of the synchronous belt 8.

[0030] The first guide roller 2 and the second guide roller 3 are rotatably installed on the two mounting wall plates 1 through bearings. The third guide roller 4 is rotatably installed on the two mounting seats 10 through bearings. A driving motor 14 is installed on one of the mounting wall plates 1 at a corresponding position. The output shaft of the driving motor 14 is in driving connection with the end of one of the transmission roller shafts 6. The driving motor 14 can drive the synchronous belt 8. The die-cutting assembly can directly adopt an existing die-cutting mechanism. For example, it includes a die-cutting roller and a power roller. The power roller is below the die-cutting roller. The material is passed between the die-cutting roller and the power roller. The power roller is provided with a motor at one end to drive the power roller to rotate. The die-cutting roller is rotatably installed above the power roller. The die-cutting roller can directly adopt an existing die-cutting roller. In this device, an existing intermittent die-cutting roller with blades intermittently arranged thereon can be adopted to realize intermittent die-cutting. Since the die-cutting assembly is very common at present, and its specific structure and die-cutting mode are not the improvements of this application, they will not be described here.

[0031] A tensioning mechanism is arranged at the lower half of the synchronous belt 8. The tensioning mechanism can directly adopt an existing tensioning structure.

[0032] As shown in Figure 1 When working, the material is pulled left and right, and is sequentially passed through the first guide roller 2, the third guide roller 4, the second guide roller 3 and the die-cutting assembly on the left side, is die-cut, and then is sequentially passed through the second guide roller 3, the third guide roller 4 and the first guide roller 2 on the right side, and is finally taken out. When the driving motor 14 drives the synchronous belt 8 to transmit to the right, the material at the die-cutting assembly will move to the left under the combined action of the traction force and the synchronous belt 8 to retreat. When the driving motor 14 drives the synchronous belt 8 to transmit to the left, the material at the die-cutting assembly will move to the right under the superimposed action of the traction force and the synchronous belt 8 to realize accelerated transmission. By controlling the driving motor 14 to work, the material cooperates with the die-cutting roller of the die-cutting assembly to work to realize the intermittent die-cutting process.
