[0002] The plotter is a terminal device. Users can send instructions to the plotter through the computer, and the computer drives and controls the working mode of the plotter. The plotter mainly uses its own tool to cut, and cuts the text or pattern designed by the computer application program on the flexible medium (such as paper, PVC film and plastic film, etc.) according to the instructions.

[0003] During the use of the engraving machine, the replacement of the cutter head has always been a key technical link. The traditional cutter head replacement structure of the engraving machine is often simple in design and lacks a precise limiting mechanism, which leads to complicated operation and low efficiency when replacing the cutter head. There is also a risk of the cutter head not being installed properly or being installed too tightly, which not only affects the normal operation of the engraving machine, but may also cause damage to the cutter head and increase the cost of use. Therefore, we propose a cutter head replacement structure for the engraving machine. Utility Model Content

[0024] See also Figure 1-4The utility model provides a technical solution: a cutting head replacement structure for a plotter, comprising a plotter frame 1, a plotter case 2, a guide rail 3 and a plotter trolley 4, the plotter case 2 is fixedly connected to the top of the plotter frame 1, the guide rail 3 is welded inside the plotter case 2, the plotter trolley 4 is slidably connected to the guide rail 3, one side of the plotter trolley 4 is fixedly connected with a clamping seat 5, the side of the clamping seat 5 away from the plotter trolley 4 is rotatably connected with a rotating seat 6, the opposite surfaces of the clamping seat 5 and the rotating seat 6 are provided with a card slot for easy fixation, the top of the rotating seat 6 is provided with a fixing groove 7, and a tool replacement structure is provided on the plotter 4.

[0025] The tool replacement structure includes a tool seat 8, a magnetic block 12, a pressing rod 11 and a tool head 13. The tool seat 8 is clamped on the slot between the clamping seat 5 and the rotating seat 6. The magnetic block 12 is slidably connected to the inside of the tool seat 8. The top of the magnetic block 12 contacts the limit plate in the tool seat 8. The pressing rod 11 is fixedly connected to the top of the magnetic block 12. The top of the pressing rod 11 slides through the limit plate and extends to the outside of the tool seat 8. The tool head 13 is magnetically attracted in the conical groove at the bottom of the magnetic block 12.

[0026] The inside of the knife seat 8 is fixedly connected to the limit bearing 15, and the inner wall of the limit bearing 15 is provided with a receiving groove 19. The inside of the receiving groove 19 is slidably connected to the limit slider 18. The side of the limit slider 18 away from the knife head 13 is fixedly connected with a pull rod 16, and the end of the pull rod 16 away from the limit slider 18 slides through the outer surface of the knife seat 8. The outer surface of the knife head 13 is sleeved with a second spring 14, the top end of the second spring 14 is fixedly connected to the magnetic block 12, and the bottom end of the second spring 14 is fixedly connected to the limit bearing 15. The outer surface of the pull rod 16 is sleeved with a third spring 17, one end of the third spring 17 is fixedly connected to the limit slider 18, and the end of the third spring 17 away from the limit slider 18 is fixedly connected to the inner wall of the receiving groove 19.

[0027] The clamping seat 5 is internally slidably connected with a fixing rod 10, the bottom end of which is plugged into the fixing groove 7, the outer surface of which is sleeved with a first spring 9, the top end of which is fixedly connected to the outer surface of the fixing rod 10, and the bottom end of which is fixedly connected to the clamping seat 5.

[0028] Furthermore, when using the device, the user pulls up the fixing rod 10, which pulls up the first spring 9. When the fixing rod 10 is disengaged from the fixing slot 7, the user rotates the rotating seat 6 to facilitate the removal of the tool holder 8. When the tool head 13 needs to be replaced, the user pulls the pull rod 16, which drives the limiting slider 18 to retract into the storage slot 19. The limiting slider 18 moves and compresses the third spring 17, so that the limiting slider 18 is disengaged from the tool head 13. Subsequently, the user presses the pressing rod 11, which drives the magnetic block 12 to move the tool head 13 downward. The magnetic block 12 moves downward and compresses the second spring 14, thereby facilitating the extrusion of the tool head 13, and the tool head can be quickly replaced.

[0029] Through the cooperation of the pressing rod 11, the magnetic block 12, the second spring 14, the third spring 17, the limit bearing 15, the limit slider 18 and the pull rod 16, the limit slider 18 can clamp the cutter head 13 under the support of the third spring 17 to prevent the cutter head 13 from falling off after installation, so that the limit bearing 15 can limit the cutter head 13, so that after the cutter head 13 is installed in the cutter seat 8, the magnetic block 12 can quickly absorb the cutter head 13 in the cutter seat 8, so as to facilitate the rapid fixation of the cutter head 13, thereby making the cutter head 13 more stable after installation, and further improving the convenience of replacing the cutter head 13.

[0030] Through the cooperation of the first spring 9 and the fixing rod 10, the fixing rod 10 is plugged into the fixing groove 7 on the rotating seat 6 under the action of the first spring 9, so as to facilitate the rapid opening and closing of the rotating seat 6 and further facilitate the disassembly of the knife seat 8.

[0031] Working principle: by the user pulling up the fixing rod 10, the fixing rod 10 pulls up and stretches the first spring 9. When the fixing rod 10 is disengaged from the fixing slot 7, the user rotates the rotating seat 6 to facilitate the removal of the knife seat 8. When the cutter head 13 needs to be replaced, the user pulls the pull rod 16, and the pull rod 16 drives the limiting slider 18 to retract into the storage slot 19. The limiting slider 18 moves and compresses the third spring 17, so that the limiting slider 18 is disengaged from the cutter head 13. Then, the user presses the pressing rod 11, and the pressing rod 11 drives the magnetic block 12 to move the cutter head 13 downward. The magnetic block 12 moves downward and compresses the second spring 14, thereby facilitating the extrusion of the cutter head 13, and the cutter head can be quickly replaced.

[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
