Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached Figures 1-6 drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0024] As shown in the figure, a cutter mechanism for cutting hot stamping paper includes a frame 1, on which a number of cutter assemblies 2 are arranged side by side. The cutter assembly 2 includes a cutter arm 21, a circular cutter 22 and a transmission frame 23. One end of the cutter arm 21 forms a first stub 211, and the other end forms a second stub 212. A sliding support rod 11 is fixedly arranged on the frame 1, and the second stub 212 is slidably inserted through the sliding support rod 11. The circular cutter 22 is rotatably connected to the first stub 211. The transmission frame 23 is slidably inserted through the sliding support rod 11, and the transmission frame 23 has two transmission plates 231 respectively located on one side of the two end faces of the second stub 212 and in contact with the end face of the second stub 212. The cross section of the sliding support rod 11 is circular, and the through hole of the transmission frame 23 inserted through the sliding support rod 11 is circular. A transmission lead screw 12 parallel to the sliding support rod 11 and screwed to the transmission frame 23 is rotatably arranged on the frame 1, and the transmission lead screw 12 is in transmission connection with a first motor 13 arranged on the frame 1.

[0025] Specifically, the cutter assembly 2 further includes a gear 24. A transmission shaft 14 parallel to the sliding support rod 11 is rotatably arranged on the frame 1. The transmission shaft 14 is in transmission connection with a second motor 15 arranged on the frame 1, and the cross section of the transmission shaft 14 is semi-circular. The transmission frame 23 is slidably inserted through the transmission shaft 14, and the through hole of the transmission frame 23 inserted through the transmission shaft 14 is circular. The gear 24 is slidably inserted through the transmission shaft 14 between the two transmission plates 231. The through hole of the gear 24 inserted through the transmission shaft 14 is semi-circular, so that the gear 24 can rotate with the transmission shaft. A transmission tooth 213 meshing with the gear 24 is formed on the circumferential side of the second stub 212.

[0026] In the above embodiments, when it is necessary to adjust the width of the slit, the first motor 13 drives the transmission lead screw 12 to rotate. The transmission lead screw 12 drives a plurality of transmission brackets 23 to move synchronously along the length direction of the sliding support rod 11 on the sliding support rod 11 through the screw connection with the transmission bracket 23. During the movement of the transmission bracket 23, since the two transmission plates 231 are abutted against the two end faces of the second stub 212, the transmission plate 231 drives the second stub 212 to slide synchronously on the sliding support rod 11 when moving with the transmission bracket 23, thereby driving the knife arm 21 and the circular cutter 22 to slide synchronously on the sliding support rod 11, adjusting the distance between the circular cutters 22 on two adjacent cutter assemblies 2, and realizing the adjustment of the slit width, better meeting the requirements for the slit width in the production of the bronzing paper. Moreover, the process of adjusting the slit width is very convenient and does not require manual operation. During the above process of adjusting the slit width, while the transmission bracket 23 drives the second stub 212 to move on the sliding support rod 11, it also drives the gear 24 to move on the transmission shaft 14 through the abutment of the two transmission plates 231 against the end face of the gear 24, so that the gear 24 always remains meshed with the transmission tooth 213. When the slit width adjustment is completed and the slitting operation is carried out, the second motor 15 drives the transmission shaft 14 to rotate, driving the gear 24 to rotate. The gear 24 drives the second stub 212 to rotate on the sliding support rod 11 through the cooperation with the transmission tooth 213, and then drives the knife arm 21 to swing on the sliding support rod 11. By the swing of the knife arm 21, the depth at which the circular cutter 22 cuts into the bronzing paper during slitting is driven, so as to adapt to the slitting operations of bronzing papers with different thicknesses, having better applicability and being able to better meet the production requirements. In addition, before or after the slitting operation starts, the circular cutter 22 is driven to swing upward and away from the bronzing paper by the swing of the knife arm 21, facilitating the feeding before the slitting operation starts or the discharging after the slitting ends.

[0027] Preferably, a rotating shaft 25 is inserted through the first stub 211. A limiting portion 251 is formed in the middle of the rotating shaft 25. One end of the rotating shaft 25 passes through the first stub 211 and is clamped with a snap ring 26, so that the limiting portion 251 abuts against the end face of the first stub 211. The snap ring 26 and the limiting portion 251 cooperate to rotatably connect the rotating shaft 25 to the first stub 211. The circular cutter 22 is inserted through the other end of the rotating shaft 25. A fastening nut 28 that abuts against the circular cutter 22 is screwed on the other end of the circular cutter 22. With the above structure, the circular cutter 22 rotates with the rotating shaft 25 to slit the bronzing paper during the slitting operation. When it is necessary to replace the circular cutter 22, unscrew the fastening nut 28 and remove the circular cutter 22 from the rotating shaft 25, which is convenient for the disassembly and assembly operation of the circular cutter 22, and thus facilitates the replacement of the circular cutter 22.

[0028] Preferably, a bearing groove 214 is formed on each of the two end faces of the first terminal 211. A bearing 215 is arranged in each of the two bearing grooves 214. The snap ring 26 abuts against the inner ring of one bearing 215, and the limiting portion 251 abuts against the inner ring of the other bearing 215. The bearing 215 ensures the smoothness and stability of the rotation of the rotating shaft 25 on the first terminal 211, and thus ensures the smoothness and stability of the circular cutter 22 when cutting and splitting the bronzing paper.

[0029] Further, the cutter assembly 2 further includes a dust suction hood 29 with an opening at the lower end. The dust suction hood 29 is connected to the first terminal 211 to cover the upper half of the circular cutter 22, and a connecting pipe 291 communicating with the inside of the dust suction hood 29 is connected to the dust suction hood 29.

[0030] Specifically, the structure of the dust suction hood 29 connected to the first terminal 211: a first connecting ring 292 is formed on the dust suction hood 29. A second connecting ring 293 is hinged to the first connecting ring 292. After the second connecting ring 293 is connected to the first connecting ring 292 by bolts, it cooperates with the first connecting ring 292 to clamp on the first terminal 211, so that the dust suction hood 29 is fixedly connected to the first terminal 211.

[0031] In the above preferred embodiment, the connecting pipe 291 is connected to an external dust suction device. While the circular cutter 22 cuts and splits the bronzing paper, the opening of the dust suction hood 29 faces the bronzing paper. The dust suction device sucks away the dust and debris generated when the circular cutter 22 cuts and splits the bronzing paper through the dust suction hood 29, so as to ensure the cleanliness of the bronzing paper after cutting. Moreover, by loosening the bolts, the first connecting ring 292 and the second connecting ring 293 can rotate on the first terminal 211, and thus the orientation of the opening of the dust suction hood 29 can be adjusted. When the knife arm 21 swings and adjusts, the opening of the dust suction hood 29 always faces the bronzing paper, so as to ensure the dust suction effect.

[0032] Preferably, two mounting blocks 294 are formed on the inner wall of the dust suction hood 29 and are respectively located on one side of the two end faces of the circular cutter 22. A scraper 295 abutting against the end face of the circular cutter 22 is connected to the mounting block 294. The scraper 295 is made of rubber material. While the circular cutter 22 rotates, the scraper 295 scrapes across the end face of the circular cutter 22, and scrapes off the dust and debris attached to the end face of the circular cutter 22 during the cutting operation and is sucked away, ensuring the cleanliness of the circular cutter 22 and thus ensuring the cutting effect.

[0033] Preferably, a connecting portion 2951 with a T-shaped cross section is formed at the end of the scraper 295. A T-shaped groove 2941 matching the connecting portion 2951 is formed on the mounting block 294. The connecting portion 2951 is inserted into the T-shaped groove 2941 to connect the scraper 295 to the mounting block 294. In this way, the disassembly and assembly of the scraper 295 are facilitated, and thus the replacement of the scraper 295 is facilitated.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
