[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model is provided with a convenient cutter installation structure. When installing, it is only necessary to align the installation block with the groove of the die-cutting seat and insert the former. Then, a tool is used to rotate the adjusting wheel, so that the adjusting wheel drives the worm to rotate. The contact surface between the worm and the worm wheel forms a spiral friction transmission surface. The rotation of the worm drives the worm wheel to rotate, and then the shaft at the lower end of the worm wheel drives the wheel to rotate. Under the meshing of the rack on the inner side of the movable rod and the gear, the rotational motion is converted into linear motion. The movable rod drives the insert block to extend outward until it enters the slot on the side wall of the die-cutting seat groove, thereby fixing the cutter assembly at this position. The installation structure is not only convenient and easy to operate, but also utilizes the self-locking property of the worm and worm wheel to improve the firmness of the cutter assembly, thereby improving the die-cutting quality.

[0017] 2. The utility model provides an air hole inside the plug block on one side. During the installation of the cutter assembly, as the plug block continues to extend, the rubber pad at one end thereof first contacts the inner wall of the slot. As the extrusion force increases, the rubber pad is closely in contact with the inner wall of the slot, and the sealed connection between the rubber tube and the air hole can be ensured. The other end of the air hole is connected to the air pipe inside the mounting block through a retractable bellows. The lower end of the air pipe is connected to the bottom of the mounting block and is located inside the cutter. After the cutter die-cuts the tape, the air pump at one end of the rubber tube is turned on to transport air to the air pipe through the rubber tube, thereby spraying inside the cutter and blowing the tape die-cut by the cutter into the storage cavity of the base, so as to facilitate subsequent collection. The blowing structure can prevent the tape from sticking to the cutter during the die-cutting process, thereby causing trouble to the subsequent die-cutting work. BRIEF DESCRIPTION OF THE DRAWINGS

A gear 19 is installed above the middle position inside the mounting block 13. The outside of the gear 19 is provided with a ring-shaped movable rod 20. A rack 21 is fixedly arranged on the inner side of the movable rod 20, and the rack 21 is meshed and connected with the gear 19. One end of the movable rod 20 is provided with an insert block 14, and the insert block 14 is located in the storage cavity inside the four sides of the mounting block 13, and the insert block 14 is limited by sliding with the mounting block 13;

[0026] The slots 22 are arranged in the four inner walls of the groove of the die-cutting seat 3 , and the inserting block 14 is plugged into and matched with the slots 22 .

[0027] During installation, the mounting block 13 needs to be aligned with the groove of the die-cutting seat 3 and the former needs to be inserted. Then, the adjusting wheel 18 needs to be rotated using a tool so that the adjusting wheel 18 drives the worm 25 to rotate. The contact surface between the worm 25 and the worm wheel 24 forms a spiral friction transmission surface. The rotation of the worm 25 drives the worm wheel 24 to rotate, and then the shaft at the lower end of the worm wheel 24 drives the gear 19 to rotate. Under the meshing of the rack 21 on the inner side of the movable rod 20 and the gear 19, the rotational motion is converted into linear motion. The insert block 14 is extended outwardly through the movable rod 20 until it enters the slot 22 on the side wall of the groove of the die-cutting seat 3, thereby fixing the cutter assembly 4 at this position.

[0028] See also Figure 2 and Figure 4 A top block 17 is fixedly provided on the upper end surface of the mounting block 13, a worm gear 24 is rotatably mounted inside the top block 17, and the shaft at the lower end of the worm gear 24 is fixed to the gear 19, a worm 25 is mounted on one side of the worm gear 24, and the external thread of the worm 25 is matched with the worm gear 24. This mounting structure is not only convenient and easy to operate, but also utilizes the self-locking property of the worm 25 and the worm gear 24 to improve the firmness of the cutter assembly 4, thereby improving the die-cutting quality.

[0029] See also Figure 2 A rubber pad 15 is provided on the outer wall of the plug block 14, and the rubber pad 15 is adhered and fixed to the plug block 14 to improve the fastening effect and sealing performance.

[0030] See also Figure 2 , Figure 3 and Figure 4 The lower end of the mounting block 13 is provided with an air pipe 27 connected to the bottom, a cutter 26 is fixedly installed at the bottom of the mounting block 13, and the outlet of the air pipe 27 is located inside the cutter 26, an air hole 16 penetrating to the outside is provided inside the plug block 14 on one side, and one end of the air hole 16 is connected to the other end of the air pipe 27 through a bellows 23, a rubber tube 8 is installed on one side of the mounting block 13, the outlet of the rubber tube 8 is connected to the slot 22 on one side, and the outlet of the rubber tube 8 corresponds to the position of the air hole 16, the blowing structure can prevent the tape from sticking to the cutter during the die-cutting process, thereby causing trouble to the subsequent die-cutting work.

[0031] See also Figure 1 A slot 7 is provided on one side of the support frame 2, and one end of a rubber tube 8 passes through the slot 7 and extends to the outside of the support frame 2. An air pump is installed at one end of the rubber tube 8 located outside the support frame 2 to facilitate the lifting and lowering movement of the die-cutting seat 3.

[0032] See also Figure 2 An adjusting wheel 18 is rotatably mounted on one side of the front end of the top block 17, and the adjusting wheel 18 is fixed to the front end of the worm 25. An octagonal hole is provided inside the adjusting wheel 18 for easy operation using tools.

[0033] See also Figure 1 A first guide assembly 9 is provided at the front and rear ends of the base 1, and a second guide assembly 10 is provided at one side of the first guide assembly 9 close to the support frame 2. The first guide assembly 9 and the second guide assembly 10 are both composed of a fixed rod 11 and a guide roller 12. The bottom of the fixed rod 11 is fixed to the base 1, and the guide roller 12 is rotatably connected to the fixed rod 11. The guide roller 12 on the first guide assembly 9 is higher than the guide roller 12 on the second guide assembly 10, so as to improve the guidance of the tape and improve the conveying stability.

[0034] Working principle: During the installation of the cutter assembly 4, as the plug block 14 continues to extend, the rubber pad 15 at one end thereof preferentially contacts the inner wall of the slot 22. As the extrusion force increases, the rubber pad 15 is tightly in contact with the inner wall of the slot 22. At this time, the sealed connection between the rubber tube 8 and the air hole 16 can be ensured. The other end of the air hole 16 is connected to the air pipe 27 inside the mounting block 13 through a retractable bellows 23. The lower end of the air pipe 27 is connected to the bottom of the mounting block 13 and is located inside the cutter 26. After the cutter 26 die-cuts the tape, the air pump at one end of the rubber tube 8 is turned on to transport air to the air pipe 27 through the rubber tube 8, thereby spraying inside the cutter 26 and blowing the tape die-cut by the cutter 26 into the storage cavity of the base 1, so as to facilitate subsequent collection.
