[0036] Specifically, the servo motor 201 is operated by operating the control panel 110. The output end of the servo motor 201 is fixedly connected to a threaded rod 202. The operation of the servo motor 201 causes the threaded rod 202 to rotate. A sleeve block 205 is threadedly connected to the threaded rod 202. The rotation of the threaded rod 202 causes the sleeve block 205 to move. Side plates 206 are fixedly connected to both sides of the sleeve block 205. The movement of the sleeve block 205 causes the side plates 206 to drive the moving seat 207 to move, thereby facilitating the sliding of the pulley 208 on the moving seat 207 on the sliding rod 209 and increasing the stability of the movement of the pull rod 3.

[0037] In one embodiment of this invention, the roller pressing assembly includes a pull rod 3 fixedly connected to the bottom end of the movable seat 207.

A limiting seat 307 is provided, with a limiting rod 308 fixedly connected to the top of the limiting seat 307. A baffle 309 is fixedly connected to the bottom of the limiting rod 308. A limiting plate 310 is fixedly connected to the top of the limiting rod 308. A docking plate 311 is fixedly connected to one side of the fixing plate 301. A pair of arc-shaped grooves 312 are provided on the docking plate 311. The top of the limiting rod 308 extends to the top of the docking plate 311 through the arc-shaped grooves 312. A first spring 313 is sleeved on the limiting rod 308. The two ends of the first spring 313 are respectively in contact with the baffle 309 and the bottom of the docking plate 311.

[0038] Specifically, the bottom end of the pull rod 3 is fixedly connected to the fixed plate 301. The movement of the pull rod 3 drives the fixed plate 301 to move. A first rotating shaft 303 is rotatably connected to the fixed plate 301, and a pull plate 304 is rotatably connected to the first rotating shaft 303. The other end of the pull plate 304 is rotatably connected to a second rotating shaft 305, and a roller 306 is fixedly connected to the second rotating shaft 305. The limit seat 307 is pushed downward by the elastic force of the first spring 313. The bottom end of the limit seat 307 is sleeved on the second rotating shaft 305, so that the roller 306 can be pressed against the surface of the cardboard on the processing table 102 to smooth it out and avoid wrinkles.

[0039] As one embodiment of this example, the fixing component includes a pair of positioning rods 4 fixedly connected to both sides of the base plate 1. A slide plate 401 is slidably connected between the pair of positioning rods 4. A pressure plate 402 is fixedly connected to the bottom end of the slide plate 401. The pressure plate 402 fits into the slot 104. A limiting plate 404 is fixedly connected to the top end of the pair of positioning rods 4. A second spring 405 is sleeved on the positioning rod 4. The two ends of the second spring 405 are fixedly connected to one side of the slide plate 401 and the bottom surface of the limiting plate 404, respectively. A sleeve rod 406 is fixedly connected to the middle of the top surface of the slide plate 401. A lead screw 407 is threaded inside the sleeve rod 406. The lead screw 407 is rotatably connected to the limiting plate 404. A turntable 408 is fixedly connected to the top end of the lead screw 407.

[0040] Specifically, the cardboard to be printed is placed inside the placement slot 103, and then the turntable 408 is rotated. The turntable 408 is fixedly connected to the lead screw 407. The rotation of the turntable 408 drives the lead screw 407 to rotate. The bottom end of the lead screw 407 is threadedly connected to the sleeve rod 406. The rotation of the lead screw 407 causes the sleeve rod 406 to push the slide plate 401 to move, so that the two ends of the slide plate 401 can slide on the positioning rod 4. A pressure plate 402 is fixedly connected to the bottom end of the slide plate 401. The movement of the slide plate 401 causes the pressure plate 402 to fix the cardboard inside the placement slot 103.

[0041] The working principle of this invention is as follows: The servo motor 201 is operated by operating the control panel 110. The output end of the servo motor 201 is fixedly connected to a threaded rod 202. The operation of the servo motor 201 causes the threaded rod 202 to rotate. A sleeve block 205 is threadedly connected to the threaded rod 202. The rotation of the threaded rod 202 causes the sleeve block 205 to move. Side plates 206 are fixedly connected to both sides of the sleeve block 205. The movement of the sleeve block 205 causes the side plates 206 to drive the moving seat 207 to move, thereby facilitating the sliding of the pulley 208 on the moving seat 207 on the sliding rod 209 and increasing the stability of the movement of the pull rod 3.

[0042] The bottom end of the pull rod 3 is fixedly connected to the fixed plate 301. The movement of the pull rod 3 drives the fixed plate 301 to move. A first rotating shaft 303 is rotatably connected to the fixed plate 301, and a pull plate 304 is rotatably connected to the first rotating shaft 303. The other end of the pull plate 304 is rotatably connected to the second rotating shaft 305, and a roller 306 is fixedly connected to the second rotating shaft 305. The limit seat 307 is pushed downward by the elastic force of the first spring 313. The bottom end of the limit seat 307 is sleeved on the second rotating shaft 305, so that the roller 306 can be pressed against the surface of the cardboard on the processing table 102 to smooth it out and avoid wrinkles.

[0043] The cardboard to be printed is placed inside the placement slot 103, and then the turntable 408 is rotated. The turntable 408 is fixedly connected to the lead screw 407. The rotation of the turntable 408 drives the lead screw 407 to rotate. The bottom end of the lead screw 407 is threadedly connected to the sleeve rod 406. The rotation of the lead screw 407 causes the sleeve rod 406 to push the slide plate 401 to move, so that the two ends of the slide plate 401 can slide on the positioning rod 4. A pressure plate 402 is fixedly connected to the bottom end of the slide plate 401. The movement of the slide plate 401 causes the pressure plate 402 to fix the cardboard inside the placement slot 103.

[0044] This invention also provides an environmentally friendly paperboard ink printing process, comprising the following steps:

[0045] Step 1: Place the cardboard in the placement slot 103 on the processing table 102, and then rotate the turntable 408 so that the sleeve rod 406 pushes the pressure plate 402 on the slide plate 401 to adhere to the top two sides of the cardboard for fixing.

[0046] Step 2: During printing, the printing press is placed on the fixed plate 301, and then the fixed plate 301 is moved as a whole by the operation of the servo motor 201, so that the roller 306 can smooth the surface of the cardboard to be printed and avoid wrinkles on the surface of the cardboard.

[0047] Step 3: The printing press prints on the surface of the cardboard on the processing table 102 by the continuous movement of the fixed plate 301. After printing is completed, the turntable 408 is rotated in the opposite direction to facilitate the removal of the cardboard for drying.
