A set of fourth motors 412 are installed on the output ends of the five electric push rods 411, and a set of fourth fixed plates 413 are drivingly connected to the output ends of each set of the fourth motors 412. A set of first buffer plates 414 are installed on one side wall of each set of the fourth fixed plates 413, and a set of fifth fixed plates 415 are installed on one side wall of each set of the fourth fixed plates 413 close to the first buffer plates 414. A set of sleeve tubes 416 are installed on the bottom of each set of the fifth fixed plates 415, and one end of a set of compression springs 417 are installed on the top inner wall of each set of the sleeve tubes 416, and the other end of each set of the compression springs 417 is installed on A group of sliding rods 418 are installed, and each group of the sliding rods 418 is slidably connected in the sleeve tube 416.

[0049] The printing paper is placed on one of the auxiliary plates 103 through the feed box 102, and then the fourth electric push rod 403 is started to drive one of the first pressure relief plates 414 to move to just below the edge of the printing paper, and then the sixth electric push rod 420 is started to drive the first electromagnetic block 421 to magnetically connect with the second electromagnetic block 422, and then the sixth electric push rod 420 is started to drive the second pressure relief plate 423 installed on the sliding rod 418 to rise, so that the first pressure relief plate 414 and the second pressure relief plate 423 are out of the fitted state, and during the rising process, the sliding rod 418 is driven to squeeze the compression spring 417, and then the second electric slide 401 is started to drive the first pressure relief plate 414 to rise, so that the edge surface of the printing paper is attached to the first pressure relief plate 414, and then the magnetic connection between the first electromagnetic block 421 and the second electromagnetic block 422 is broken, and the compression spring 417 feels the pressure disappear. The printing paper starts to rebound when the delay occurs, and during the rebound process, the second pressure relief plate 423 is driven to contact the surface edge of the printing paper, and then the fourth electric push rod 403 drives the printing paper to reset, and the second motor 405 is started to drive the disc body 406 to rotate. After the disc body 406 rotates to the specified position, the printing paper naturally droops due to gravity, and then the third motor 410 is started to drive the threaded rod 407 to rotate, and the threaded rod 407 drives the sliding block 409 to slide in the sliding cavity, thereby driving the two groups of fourth fixed plates 413 to move towards each other. When they move to the specified position, another group of first pressure relief plates 414 is started to cooperate with the second pressure relief plate 423 to limit the other end surface edge of the printing paper, and then the second motor 405 is reset, which improves the limiting effect and the self-flattening effect of the printing paper, avoids paper damage and improves the compatibility effect of paper size limiting.

[0050] When turning the printing paper over, the second electric slide 401 is started to drive the printing paper to rise, and then the second motor 405 is started to drive the disc body 406 to rotate, thereby improving the double-sided printing effect of the device; after the printing work is completed, the fourth electric push rod 403 is started to drive the printing paper to move toward the direction close to the discharge box 104, and then the two sets of pressure relief plates are separated from the limiting effect of the printing paper during the taking process.

[0051] The carrier plate 307 is driven to move to the position directly below the printing paper that needs inkjet, and the third electric push rod 306 is started to drive the carrier plate 307 to move synchronously according to the printing position of the inkjet printing structure 210. On the printing paper that has just been inkjetted, the ink is prone to backflow and diffusion. At this time, one of the groups of heat transfer devices 304 is started to dry the position where the ink has just been sprayed, which speeds up the drying progress and expands the effect of fixed-point drying. In addition, when ink is scattered during the fixed-point drying process, it can be discovered in time, avoiding the problem of resource loss and improving the working effect of the double-sided printing machine.

[0052] Before the inkjet printing structure works, the heating box 204 is first started to transport hot air into the sleeve tube 202, so that the hot air in the sleeve tube 202 can heat the ink in the storage tube 201, making the subsequent inkjet work more thorough, and during the working process, the first electric push rod 207 is started to drive the stirring tube 209 to enter the storage tube 201, and then the first motor 208 is started to stir the ink, so that the ink delivery components are more thorough, which improves the inkjet effect and the subsequent printing effect.

[0053] The second motor 405 is started to drive the disc body 406 to rotate. After the disc body 406 rotates to the specified position, the printing paper naturally droops due to gravity. Then the third motor 410 is started to drive the threaded rod 407 to rotate. The threaded rod 407 drives the sliding block 409 to slide in the sliding cavity, and then drives the two groups of fourth fixed plates 413 to move towards each other. When they move to the specified position, another group of first buffer plates 414 is started to cooperate with the second buffer plates 423 to limit the edge of the other end surface of the printing paper, and then the second motor 405 is reset; thereby avoiding damage to the paper and improving the compatibility effect of the paper size limit.

[0054] The sixth electric push rod 420 is started to drive the second pressure relief plate 423 installed on the sliding rod 418 to rise, so that the first pressure relief plate 414 and the second pressure relief plate 423 are out of the fitted state, and during the rising process, the sliding rod 418 is driven to squeeze the compression spring 417, and then the second electric slide 401 is started to drive the first pressure relief plate 414 to rise, so that the edge surface of the printing paper is fitted on the first pressure relief plate 414, and then the magnetic connection between the first electromagnetic block 421 and the second electromagnetic block 422 is separated, and the compression spring 417 begins to rebound when it senses that the pressure disappears, and during the rebound process, the second pressure relief plate 423 is driven to contact the surface edge of the printing paper, thereby improving the limiting effect and the self-flattening effect of the printing paper.
