When the machine needs to be changed to a different size die-cutting device, the operator presses the first and second buttons on both sides of the side panel. The first button presses on the front end of the first connecting rod, the first rotating shaft rotates, the end of the first connecting rod lifts up, and the first magnetic suction slot lifts up. At this time, the first magnetic suction slot and the first magnetic suction buckle are not attracted to each other, and the first spring is in a relaxed state, which pops the first fixing rod upward. The second button presses on the front end of the second connecting rod, the second rotating shaft rotates, the end of the second connecting rod lifts up, and the second magnetic suction slot lifts up. At this time, the second magnetic suction slot and the second... When the magnetic latch is not engaged, the second spring is in a relaxed state, causing the second fixing rod to pop upwards.

Detailed Implementation

[0020] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0021] Please see Figure 1-4 This embodiment provides a technical solution: a die-cutting device for graphite film processing, including a base 1, a PLC controller 2 and a lifting mechanism 3 respectively installed on the top of the base 1, a lifting seat 10 fixed on the lifting part of the lifting mechanism 3, a chain plate conveyor 9 installed on the inner side of the lifting seat 10, mounting frames 8 evenly fixed on the conveying chain of the chain plate conveyor 9, an elastic mechanism 5 installed on the mounting frame 8, a connecting seat 7 fixed at the end of the elastic mechanism 5, a roller seat 12 detachably connected to the connecting seat 7 through a connecting mechanism 4, a die-cutting roller 13 rotatably installed on the roller seat 12, a quick-release auxiliary mechanism 6 for driving the elastic mechanism 5 to move is installed on the side of the lifting seat 10 corresponding to the position of the elastic mechanism 5, a transmission roller 11 is rotatably installed on the top stand of the base 1, and the PLC controller 2 is electrically connected to the chain plate conveyor 9 and an external power supply respectively.

[0022] The lifting mechanism 3 includes a first electric push rod 31 and a connecting frame 32. The first electric push rod 31 is installed on the top of the base 1, and the connecting frame 32 is fixed to the telescopic end of the first electric push rod 31. The lifting seat 10 is fixed to the side of the connecting frame 32. The first electric push rod 31 is electrically connected to the PLC controller 2. When it is necessary to replace the die-cutting roller 13, the telescopic end of the first electric push rod 31 drives the lifting seat 10 to move up and down through the connecting frame 32, thereby separating the die-cutting roller 13 from the transmission roller 11. Then, the conveyor chain of the chain conveyor 9 drives the mounting frame 8 to move. The mounting frame 8 drives the connecting seat 7 to move through the elastic mechanism 5. The connecting seat 7 drives the roller seat 12 to move through the connecting mechanism 4, thereby moving the corresponding die-cutting roller 13 to the position corresponding to the transmission roller 11. This makes it convenient to replace the die-cutting roller 13, saves time and effort, reduces the manual intervention process, and improves the efficiency of graphite film processing.

[0023] The elastic mechanism 5 includes a connecting block 51, a spring 52, and a movable rod 53. The movable rod 53 is movably connected to the mounting frame 8. The connecting block 51 is fixed to one end of the movable rod 53, and the other end of the movable rod 53 is fixedly connected to the connecting seat 7. The spring 52 is sleeved on the movable rod 53 and is located between the mounting frame 8 and the connecting seat 7. The connecting mechanism 4 includes a positioning block 41 and a positioning hole 42. The positioning block 41 is fixed to the side of the connecting seat 7, and the positioning hole 42 is opened on the roller seat 12. The positioning block 41 and the positioning hole 42 are fitted together. The quick-release auxiliary mechanism 6 includes an armature block 61 and an electromagnet 62. The armature block 61 is fixed to the side of the connecting block 51, and the armature block 61 is magnetically connected to the electromagnet 62. The electromagnet 62 is electrically connected to the PLC controller 2. The quick-release auxiliary mechanism 6 also includes a mounting block 63 and a second electric push rod 64. The second electric push rod 64 is installed on the side of the lifting seat 10, and the mounting block 63 is fixed to the telescopic end of the second electric push rod 64. The electromagnet 62 is installed on the side of the lifting seat 10. On the side of the mounting block 63, the second electric push rod 64 is electrically connected to the PLC controller 2. When the transmission roller 11 needs to be replaced or maintained, the electromagnet 62 is energized and magnetically connected to the armature block 61. Then, the telescopic end of the second electric push rod 64 drives the mounting block 63 to telescopically move, thereby causing the connecting block 51 to pull the movable rod 53 to move. The end of the movable rod 53 drives the connecting seat 7 to move, thereby separating the positioning block 41 on the connecting seat 7 from the positioning hole 42 on the roller seat 12. At this time, the die-cutting roller 13 can be removed. When installation is required, the electromagnet 62 is de-energized and loses its magnetic constraint with the armature block 61. Then, the compressed spring 52 recovers its deformation. The deformation force of the spring 52 acts on the connecting seat 7, thereby causing the positioning block 41 on the connecting seat 7 to be inserted into the positioning hole 42 on the roller seat 12. The die-cutting roller 13 can then be installed. Its installation and disassembly are convenient, making it easy to replace or maintain the die-cutting roller 13.

[0024] The working principle of the die-cutting device for graphite film processing provided by this utility model is as follows: When it is necessary to replace the die-cutting roller 13, the telescopic end of the first electric push rod 31 drives the lifting seat 10 to move up and down through the connecting frame 32, thereby separating the die-cutting roller 13 from the transmission roller 11. Then, the conveying chain of the chain plate conveyor 9 drives the mounting frame 8 to move. The mounting frame 8 drives the connecting seat 7 to move through the elastic mechanism 5. The connecting seat 7 drives the roller seat 12 to move through the connecting mechanism 4, thereby moving the corresponding die-cutting roller 13 to the position corresponding to the transmission roller 11.

[0025] When the drive roller 11 needs to be replaced or maintained, the electromagnet 62 is energized and magnetically connected to the armature block 61. Then, the telescopic end of the second electric push rod 64 drives the mounting block 63 to telescopically move, thereby causing the connecting block 51 to pull the movable rod 53 to move. The end of the movable rod 53 drives the connecting seat 7 to move, thereby separating the positioning block 41 on the connecting seat 7 from the positioning hole 42 on the roller seat 12. At this time, the die-cutting roller 13 can be removed. When installation is required, the electromagnet 62 is de-energized and loses its magnetic constraint with the armature block 61. Then, the compressed spring 52 recovers its deformation. The deformation force of the spring 52 acts on the connecting seat 7, thereby causing the positioning block 41 on the connecting seat 7 to be inserted into the positioning hole 42 on the roller seat 12, and the die-cutting roller 13 can be installed.
