Therefore, they cannot be understood as limitations on the present invention.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1 - Figure 4 As shown, a printer that is easy to replace ink cartridges includes a printer body 100, an opening 200 is provided on one side of the printer body 100, a roller gap adjustment mechanism is provided on one side of the interior of the printer body 100, and an ink cartridge installation mechanism is provided on the other side of the interior of the printer body 100, the roller gap adjustment mechanism includes two upper and lower distributed transmission rollers 301, both ends of the transmission roller 301 are fixedly connected to a roller shaft 302, the middle part of the roller shaft 302 is fixedly connected to a gear 1 303, the front and rear sides of the transmission roller 301 are provided with symmetrically distributed adjustment components, the adjustment component includes a bidirectional threaded rod 305, the upper and lower sides of the bidirectional threaded rod 305 are threadedly connected to a threaded sleeve 304, the threaded sleeve 304 is fixedly connected to the rotatable roller shaft 302, the upper and lower sides of the transmission roller 301 are provided with power components, and one side of the roller shaft 302 is provided with an engaging component for maintaining the synchronous reversal of the roller shaft 302.

[0026] The transmission roller 301 is used to transmit paper when it is synchronously reversed. The roller shaft 302 is used to install the gear 1 303 and the threaded sleeve 304. The threaded sleeve 304 moves closer to or away from each other under the rotation of the bidirectional threaded rod 305, so that the movement of the roller shaft 302 completes the spacing adjustment of the transmission roller 301.

[0027] The power assembly includes two flat plates 306, both ends of which are fixedly connected to the printer body 100, and both ends of the bidirectional threaded rod 305 are rotatably connected to the flat plates 306. The bottom end of the bidirectional threaded rod 305 is provided with a synchronization assembly 307 that keeps the bidirectional threaded rod 305 synchronously reversed. The upper flat plate 306 is installed with a motor 308, and the output shaft of the motor 308 is fixedly connected to the top of the bidirectional threaded rod 305.

[0028] The plate 306 is used to maintain the rotation of the bidirectional threaded rod 305 and limit the position of the bidirectional threaded rod 305. The motor 308 is used to drive one of the bidirectional threaded rods 305 to rotate. The two bidirectional threaded rods 305 maintain synchronous rotation under the drive of the synchronization component 307.

[0029] The meshing assembly includes a synchronization plate 312, the upper and lower sides of which are rotatably connected to gear 2 311, the gears 2 311 mesh with each other, the gear 2 311 meshes with gear 1 303, the middle part of the bidirectional threaded rod 305 is fixedly connected to gear 3 309, the gear 3 309 meshes with rack 3 310, the rack 3 310 is fixedly connected to rack 3 310, the synchronization plate 312 is fixedly connected to a slide bar 313, and the slide bar 313 is slidably connected to the printer body 100.

[0030] When the bidirectional threaded rod 305 rotates, it drives gear three 309 to rotate, thereby causing rack three 310 to move horizontally, changing the distance between the synchronization plate 312 and gear one 303, and then changing the distance between gear two 311 and gear one 303, so that when the spacing of gear one 303 is adjusted, it can maintain engagement with gear two 311. Gear two 311 engages with each other, so rack three 310 maintains synchronous reverse rotation, and finally causes gear one 303 to reverse synchronously.

[0031] The roller spacing adjustment mechanism includes a transmission motor 314 . The transmission motor 314 is mounted on the outside of the synchronization plate 312 . The output shaft of the transmission motor 314 is fixed to the second gear 311 .

[0032] The transmission motor 314 provides rotational power to drive the gear 2 311 to rotate.

[0033] The ink cartridge installation mechanism includes an ink cartridge door 401, which is installed on the top of the printer body 100. The lower part of the ink cartridge door 401 is provided with an ink cartridge body 406, and both sides of the ink cartridge body 406 are provided with snap-connecting components. A transmission component for controlling the snap-connecting component is provided on one side of the door shaft of the ink cartridge door 401.

[0034] When the ink cartridge door 401 is flipped open, it can drive the transmission assembly to release the locking assembly, and the ink cartridge body 406 can be taken out.

[0035] The snap-on assembly includes two L-shaped limit plates 408, which are fixedly connected to the printer body 100. The vertical plate of the L-shaped limit plate 408 is slidably connected to a snap-on plate 2 407, which is fixedly connected to the ink cartridge body 406. The other side of the snap-on plate 2 407 is snap-on to a snap-on plate 1 405, which is slidably connected to the printer body 100.

[0036] When the ink cartridge body 406 is placed in, the second clamping plate 407 slides down along the L-shaped limit plate 408 until it presses against the horizontal plate of the ink cartridge body 406 . When the ink cartridge door 401 is closed, the first clamping plate 405 is driven to clamp the second clamping plate 407 .

[0037] The transmission component includes two special-shaped gears 402, which are fixedly connected to the cartridge door 401. The cartridge door 401 is engaged with gear four 403, which is rotatably connected to the printer body 100. Gear four 403 is engaged with rack four 404, and rack four 404 is fixedly connected to the clamping plate one 405.

[0038] When the ink cartridge door 401 flips over, it drives the special-shaped gear 402 to rotate, causing the gear four 403 to rotate in the opposite direction, causing the rack four 404 to slide, driving the clamping plate 1 405 away from the clamping plate 2 407, so that the clamping plate 1 405 and the clamping plate 2 407 are released, and the ink cartridge body 406 can be removed.

[0039] Working principle:

[0040] The motor 308 is started, and the motor 308 drives one of the bidirectional threaded rods 305 to rotate. Under the action of the synchronization component 307, the other bidirectional threaded rod 305 also rotates synchronously in the opposite direction, so that the threaded sleeves 304 move closer to or farther away from each other, thereby adjusting the spacing of the rollers 302 and finally the spacing of the transmission rollers 301 to adapt to different thicknesses of paper.

[0041] When the bidirectional threaded rod 305 rotates, gear three 309 also rotates, driving the horizontal movement of rack three 310, causing the synchronous plate 312 and gear two 311 to move horizontally, maintaining the engagement of gear two 311 and gear one 303. Since the two gear twos 311 are engaged with each other, the two gear twos 311 rotate synchronously in opposite directions, so gear one 303 and the transmission roller 301 also rotate synchronously in opposite directions. After the transmission motor 314 is started, it drives gear two 311, gear one 303 and the transmission roller 301 to rotate and transport the paper.

[0042] When the ink cartridge body 406 needs to be removed, the ink cartridge door 401 is first opened, which drives the special-shaped gear 402 to rotate, and then the gear four 403 rotates in the opposite direction, causing the rack four 404 to move to the right, so that the clamping plate 1 405 moves to the right away from the clamping plate 2 407, completing the release of the clamping, and the ink cartridge body 406 can be easily removed.
