[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-7 As shown, this utility model is a directional rapid positioning mechanism for a greeting card die-cutting machine, including a worktable 1, and further including: a replacement part 2, which is disposed on the top of the worktable 1; and a positioning part 3, which is disposed on the bottom of the worktable 1.

[0018] The replacement unit 2 includes a replacement assembly 21, which is mounted on the top of the workbench 1; and a die-cutting assembly 22, which is mounted on the replacement assembly 21. The replacement assembly 21 includes a sliding mounting plate 211 disposed on the top of the workbench 1. A die-cutting tool 212 is slidably connected to the front of the sliding mounting plate 211. Two slide rods 213 are fixedly connected to the top of the sliding mounting plate 211. A top plate 214 is fixedly connected to the top of the two slide rods 213. A slider 215 is slidably connected to the outer wall of the two slide rods 213. A plug rod is fixedly connected to the bottom of the slider 215. 216, the insert rod 216 passes through the sliding mounting plate 211 and is slidably connected to the sliding mounting plate 211. The bottom end of the insert rod 216 extends into the die-cutting cutter 212. A handle 217 is fixedly connected to the top of the slider 215. Springs 218 are wound around the outer walls of the two slide rods 213. One end of each spring 218 is fixedly connected to the top plate 214, and the other end of each spring 218 is fixedly connected to the slider 215. The die-cutting assembly 22 includes a slide rod frame 221 fixedly connected to the top of the worktable 1. The slide rod frame 221 passes through the sliding mounting plate 211 and is slidably connected to the sliding mounting plate 212. The sliding plate 211 is slidably connected, and a hydraulic push rod 222 is fixedly connected to the top of the slide rod frame 221. The output end of the hydraulic push rod 222 is fixedly connected to the sliding mounting plate 211, and the output end of the hydraulic push rod 222 extends to the outside of the slide rod frame 221 and is slidably connected to the slide rod frame 221. By setting the replacement part 2, if it is necessary to replace the die-cutting tool 212 according to the requirements, the handle 217 can be pulled upward first. At this time, the handle 217 will, with the guidance of the slide rod 213, cause the slider 215 to drive the insert rod 216 on it from the sliding mounting plate 211 and the die-cutting tool 212. As the die-cutting cutter 212 is removed, the handle 217 moves the slider 215 upward. During this process, the top plate 214 also compresses the springs 218 on the outer walls of the two slide bars 213, allowing them to accumulate elastic potential energy to support subsequent reset. Then, simply pull the die-cutting cutter 212 outward to separate it from the sliding mounting plate 211, completing the disassembly and replacement. After replacement, follow the reverse steps of disassembly to fix the new die-cutting cutter 212. This setting allows for quick replacement of the die-cutting cutter, effectively improving the equipment's adaptability to greeting cards of different shapes.

[0019] The positioning unit 3 includes a positioning component 31, which is installed at the bottom of the worktable 1; a driving component 32, which is installed on the positioning component 31; and a pushing component 33, which is located at the top of the worktable 1. The positioning component 31 includes a slide rod assembly 311 located at the bottom of the worktable 1. Two slide plates 312 are slidably connected to the outer wall of the slide rod assembly 311. A slide groove 313 is provided on the top of the worktable 1. A connecting plate 314 is fixedly connected to the top of each of the two slide plates 312. A positioning frame 315 is fixedly connected to the side of each of the two connecting plates 314 that are close to each other. Several greeting cards 316 are provided on the top of the worktable 1. Both positioning frames 315 are in contact with several greeting cards 316. Connecting parts are provided on the two slide plates 312. The top ends of each connecting plate 314 extend outside the slide groove 313 and are slidably connected to the slide groove 313. The drive assembly 32 includes a fixed plate 321 fixedly connected to the outer wall of the slide rod assembly 311. A motor 322 is mounted on the fixed plate 321. The output shaft of the motor 322 is fixedly connected to a rotating shaft 323 via a coupling. A connecting rod 324 is fixedly connected to the outer wall of the rotating shaft 323. A motor slot is provided on the fixed plate 321, and the motor 322 is located in the slot. The push assembly 33 includes a push plate 331 slidably connected to two positioning frames 315. A connecting plate 332 is fixedly connected to the back of the push plate 331. Two hydraulic push rods 333 are mounted on the top of the worktable 1. The output ends of the two hydraulic push rods 333 are fixedly connected to the connecting plate 332. Two hydraulic push rods 333 are symmetrically distributed on both sides of the worktable 1. The connecting parts include connecting rods 317 that are hinged to the bottom of the two slide plates 312. The ends of the two connecting rods 317 away from the slide plates 312 are hinged to connecting rods 324. By setting the positioning part, when it is necessary to die-cut the greeting cards 316, a stack of greeting cards 316 can be placed between the two positioning frames 315. After placement, the motor 322 is started. The motor 322 will drive the connecting rods 324 to rotate through the rotating shaft 323. Since there are two connecting rods 317 hinged on the connecting rods 324, and the other ends of the two connecting rods 317 are hinged to the two slide plates 312 sliding on the slide rod assembly 311, the motor 322 drives the connecting rods 324 to rotate through the rotating shaft 323. During rotation, the two connecting rods 317 drive the two hinged slide plates 312 to move their respective positioning frames 315 closer or further apart, thus positioning the greeting card 316 inside. After the greeting card 316 is positioned, the two hydraulic push rods 333 are activated simultaneously. They, with the help of the connecting plate 332, drive the push plate 331 to push the greeting card 316 within the two positioning frames 315, pushing the greeting card 316 to the bottom of the die-cutting cutter 212. Subsequently, the two hydraulic push rods 333 drive the push plate 331 to reset via the connecting plate 332. After resetting, the greeting card 316 on top will fall to the same horizontal position as the push plate 331, preparing for the next push. Then, the hydraulic push rod 222 can be activated.It uses the slide bar 221 to drive the die-cutting cutter 212 on the worktable 1 to cut the greeting card 316 at the bottom. This setup enables automatic positioning, pushing, and die-cutting of the greeting card, significantly improving production efficiency and processing accuracy.

[0020] It should be noted that the control of motor 322, hydraulic push rod 222 and two hydraulic push rods 333 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.

[0021] One specific application of this embodiment is as follows: When using the die-cutting tool 212, if it needs to be replaced as required, the handle 217 can be pulled upwards first. At this time, the handle 217, guided by the slide bar 213, will cause the slider 215 to move its insert rod 216 out of the sliding mounting plate 211 and the die-cutting tool 212. During the upward movement of the slider 215 by the handle 217, the top plate 214 will also compress the springs 218 on the outer walls of the two slide bars 213, allowing them to accumulate elastic potential energy to support subsequent reset. Then, simply pull the die-cutting tool 212 outwards. Separate it from the sliding mounting plate 211 to complete the disassembly and replacement. After replacement, follow the reverse steps of disassembly to fix the new die-cutting cutter 212. This setting allows for quick replacement of the die-cutting cutter, effectively improving the equipment's adaptability to greeting cards of different shapes. When die-cutting greeting cards 316 is required, place a stack of greeting cards 316 between the two positioning frames 315. After placement, start the motor 322. The motor 322 will drive the connecting rod 2 324 to rotate via the rotating shaft 323. Since the connecting rod 2 324 is hinged with two connecting rods 1 317, and the two... The other ends of connecting rod 317 are hinged to two sliding plates 312 that slide on sliding rod assembly 311. Therefore, when motor 322 drives connecting rod 324 to rotate via shaft 323, the two hinged sliding plates 312 can be driven by the transmission of connecting rod 317 to move the positioning frames 315 closer or further apart, thereby positioning the greeting card 316 inside. After the greeting card 316 is positioned, two hydraulic push rods 333 are activated simultaneously. They will drive push plate 331 to move the greeting card 316 inside the two positioning frames 315 with the help of connecting plate 332. The greeting card 316 is pushed to the bottom of the die-cutting cutter 212. Then, the two hydraulic push rods 333 drive the push plate 331 to reset through the connecting plate 332. After resetting, the greeting card 316 on top will fall to the same level as the push plate 331, preparing for the next push. Then, the hydraulic push rod 222 can be activated, which will drive the die-cutting cutter 212 on the worktable 1 to cut the greeting card 316 at the bottom with the help of the slide rod frame 221. Through this setting, the automatic positioning, pushing and die-cutting operation of the greeting card can be realized, which greatly improves production efficiency and processing accuracy.
