[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams.

[0026] Example 1

[0027] Reference Figure 1-4 In the first embodiment of this utility model, a disassembly and assembly component 1 is provided, including a fixing frame 101 and a cutter 102. The cutter 102 is disposed in the middle of the fixing frame 101. An installation mechanism 2 is provided on the surface of the cutter 102, and an adjustment mechanism 3 is provided on the surface of the installation mechanism 2. The installation mechanism 2 is used to quickly install the cutter 102, and the adjustment mechanism 3 is used to adjust the height of the cutter 102 according to the actual situation.

[0028] Specifically, the disassembly and assembly component 1 effectively solves the problems of cumbersome replacement of the cutter 102, low positioning accuracy, and inability to adapt to different media thicknesses in traditional printers by setting up the installation mechanism 2 and the adjustment mechanism 3. The installation mechanism 2 enables the quick locking and releasing of the cutter 102, greatly improving maintenance efficiency; the adjustment mechanism 3 can adjust the height of the cutter 102 according to the actual thickness of the printing media to ensure cutting quality. The two work together to not only enhance the ease of operation of the equipment, but also improve the stability and adaptability of the cutting operation.

[0029] Furthermore, the installation mechanism 2 allows for quick installation and removal of the cutter 102, and the adjustment mechanism 3 adjusts the height of the cutter 102, thereby improving replacement efficiency and cutting adaptability.

[0030] Example 2

[0031] The second embodiment of this utility model provides an installation mechanism 2 including an electric push rod 201, a fixed plate 202, a guide rod 203, and an installation plate 204. The telescopic end of the electric push rod 201 is fixedly connected to the lower end of the fixed plate 202. Both ends of the fixed plate 202 are fixedly connected to the upper ends of the two guide rods 203. The lower ends of the guide rods 203 are fixedly connected to the upper end of the installation plate 204. The lower end of the electric push rod 201 is fixedly connected to the upper end of the fixed frame 101. The surface of the guide rod 203 is slidably connected to the inner wall of the fixed frame 101. The inner wall of the installation plate 204 is in contact with the surface of the cutter 102. The surface of the installation plate 204 is slidably connected to the inner wall of the fixed frame 101 through a sliding groove.

[0032] Specifically, the mounting mechanism 2 drives the fixed plate 202 to rise and fall via an electric push rod 201, and with the cooperation of the guide rod 203 and the inner wall groove of the fixed frame 101, the mounting plate 204 and the cutter 102 can move vertically as a whole smoothly. This structure effectively solves the problem that traditional cutting devices cannot flexibly adjust the height of the cutter 102 according to the thickness of the printing medium, and avoids the phenomenon of not being able to cut or damaging the medium due to improper cutting position. At the same time, the guiding constraint of the guide rod 203 and the groove ensures the stability during the movement, improves the adaptability of the equipment to different working conditions, and provides reliable support for the cutting operation.

[0033] Furthermore, the servo motor 302 drives the worm gear 303 to rotate, which in turn drives the cam 305 to rotate via the worm wheel 304. The contour of the cam 305 pushes the connecting rod 306 to move. The connecting rod 306 transmits the tension to the slide groove through the fixing block 307, so that the fixing block 307 is embedded in the slot of the cutter 102, thereby realizing the quick locking and installation of the cutter 102 and the mounting plate 204.

[0034] Example 3

[0035] The third embodiment of this utility model provides an adjustment mechanism 3 including a protective cover 301, a servo motor 302, a worm gear 303, a worm wheel 304, a cam 305, a connecting rod 306, and a fixing block 307. The surface of the protective cover 301 is fixedly connected to the surface of the servo motor 302. The output end of the servo motor 302 is fixedly connected to the surface of the worm gear 303. The tooth surface of the worm gear 303 meshes with the tooth surface of the worm wheel 304. The surface of the worm wheel 304 is fixedly connected to the surface of the cam 305 via the fixing rod. The surface of the cam 305 is fixedly connected to the connecting rod. The inner wall of 306 is rotatably connected by a rotating shaft. The surface of the connecting rod 306 is rotatably connected to the inner wall of the fixing block 307 by a rotating shaft. The surface of the protective cover 301 is fixedly connected to the surface of the mounting plate 204. The surface of the worm gear 303 is rotatably connected to the inner wall of the protective cover 301. The worm wheel 304 is located inside the protective cover 301. The surface of the cam 305 is rotatably connected to the inner wall of the mounting plate 204 by a sliding groove. The surface of the fixing block 307 is slidably connected to the inner wall of the mounting plate 204 by a sliding groove. The surface of the fixing block 307 is in contact with the groove on the inner wall of the cutter 102.

[0036] Specifically, the adjustment mechanism 3 drives the worm gear 303 and worm wheel 304 through a servo motor 302 to reduce speed, thereby rotating the cam 305. This, in turn, pushes the fixing block 307 along the slide groove and into the slot of the cutter 102 via the connecting rod 306, achieving rapid locking and releasing of the cutter 102. Compared with traditional screws or manual clamping methods, this improves replacement efficiency. At the same time, the worm wheel 304 and worm gear 303 have self-locking characteristics, effectively preventing the cutter 102 from loosening during operation, improving installation reliability and cutting stability, and solving the problems of cumbersome installation and disassembly and unstable positioning of the cutter 102.

[0037] Furthermore, after the cutter 102 is installed, if the cutting position needs to be adjusted according to the thickness of the medium, the electric push rod 201 can be activated to drive the fixing plate 202 to rise and fall linearly. The fixing plate 202 is equipped with guide rods 203 at both ends, which slide along the slide groove to ensure stability. The mounting plate 204 and the cutter 102 then move together to the height suitable for the thickness, providing a structural basis for cutting.

[0038] Working principle:

[0039] When quickly assembling and disassembling the printer cutter 102, first place the cutter 102 in the reserved position on the inner wall of the mounting plate 204. Then, start the servo motor 302, whose output end drives the worm gear 303 to rotate. The worm gear 303 meshes with the worm wheel 304, driving the cam 305, which is connected to the worm wheel 304 through a fixed rod, to rotate synchronously. Due to the specific contour structure of the cam 305, its two highest points contact the two connecting rods 306 through a rotating shaft during rotation, pushing them to move. The other end of the connecting rod 306 is connected to the fixed block 307 through a rotating shaft, thus transmitting the power of the servo motor 302 to the cam 305 through the worm wheel 304 and worm gear 303 mechanism, and further converting it into a pulling force of the connecting rod 306 on the fixed block 307. This pulling force causes the fixed block 307 to move along the inner wall of the mounting plate 204. The slide rail slides linearly and eventually embeds into the corresponding slot on the inner wall of the cutter 102, achieving reliable locking and quick installation between the cutter 102 and the mounting plate 204. After the cutter 102 is installed, if it is necessary to adjust the cutting position according to the actual thickness of the printing medium, the height adjustment is entered. At this time, the electric push rod 201 can be activated, and its telescopic end drives the fixing plate 202 to move linearly up and down. To ensure smooth movement and prevent deviation, guide rods 203 are provided at both ends of the fixing plate 202. These guide rods 203 slide synchronously along the slide rail on the inner wall of the fixing frame 101, playing a guiding and supporting role. As the fixing plate 202 moves, the mounting plate 204 fixed at its lower end and the installed cutter 102 also rise and fall as a whole until the ideal cutting height that adapts to the thickness of the current printing material is reached, providing a structural foundation for subsequent cutting.

[0040] In summary, through the coordinated operation of the servo motor, worm gear, cam connecting rod, electric push rod, guide rod, and slide groove structure, the quick assembly and disassembly of the cutter and its height adaptive adjustment are achieved, improving the printer's operating efficiency and cutting accuracy in diverse printing tasks.
