The transmission mechanism realizes efficient power transmission through the linkage structure of the rotating disk and the rack plate, ensuring the synchronous operation of the subsequent embossing mechanism.

The roll-out mechanism 8 includes two extension frames 801, which provide support for the unwinding roller 802 to ensure the stability of the installation of the paper roll 803 and the smoothness of the operation. The right ends of the two extension frames 801 are fixedly connected to the left end of the base 1, and the extension frames 801 are fixed on the base 1 to ensure the overall stability of the device. The top of the extension frame 801 is rotatably connected with the unwinding roller 802, and the unwinding roller 802 realizes the unwinding of the paper roll 803 by rotation, which is convenient for the subsequent processing of the paper sheets. The outside of the unwinding roller 802 is installed with a paper roll 803, which is supplied as raw material and is smoothly unrolled by the rotation of the unwinding roller 802.

[0036] The front end of the unwinding roller 802 is rotatably connected to a fixed rod 804, which is used to adjust the position of the unwinding roller 802 to ensure the accuracy of the installation of the paper roll 803. The top of one of the extension frames 801 is rotatably connected to a rotating sleeve 805, which realizes the flexible adjustment of the extension block 1 806 by rotating, so as to facilitate the installation and removal of the unwinding roller 802. One side of the rotating sleeve 805 is fixedly connected to an extension block 1 806, which cooperates with the extension block 2 807 by moving to complete the fixing or releasing operation of the paper roll 803. One side of one of the extension frames 801 is fixedly connected to an extension block 2 807, which completes the installation and fixing of the paper roll 803 by separating or sticking with the extension block 1 806. The top of the extension block 2 807 is fixedly connected to a fixed column 808, which provides support for the rotation limiting block 809 to ensure the operational stability of the device. The top of the fixed column 808 is rotatably connected to a rotation limiting block 809, which controls the contact or separation of the extension block 1 806 and the extension block 2 807 by rotation, so as to facilitate the installation operation of the paper roll 803. The bottom of the rotation limiting block 809 contacts the top of the extension block 1 806, and this contact mode ensures that the extension block 1 806 can be accurately positioned under the action of the rotation limiting block 809. The bottom of the extension block 1 806 is connected to the top of the extension block 2 807, and the contact between the two enables the paper roll 803 to be firmly fixed to avoid loosening during operation; Specifically, two extension frames 801 fixed at the left end of the base 1 provide support to ensure the installation stability and running smoothness of the unwinding roller 802 and the paper roll 803. The unwinding roller 802 installs the paper roll 803 as the raw material, and realizes the smooth unfolding of the paper sheet by rotation, providing input for subsequent processing. The fixed rod 804 is used to adjust the position of the unwinding roller 802 to ensure the installation accuracy of the paper roll 803. The rotating sleeve 805 drives the movement of the extension block 1 806 by rotation, and cooperates with the extension block 2 807 to complete the paper roll. 803 is fixed or released, the extension block 807 supports the rotation limiting block 809 through the fixed column 808, and the rotation limiting block 809 controls the separation or bonding of the extension block 1 806 and the extension block 2 807, ensuring that the installation or removal process of the paper roll 803 is accurate and efficient. The bonding of the extension block 1 806 and the extension block 2 807 firmly fixes the paper roll 803 to prevent it from loosening during operation. The whole mechanism can achieve stable installation and rapid replacement of the paper roll 803 through flexible adjustment, ensuring efficient preparation work before printing.

[0037] Working principle: when it is needed, the rotation limiting block 809 is rotated 180 degrees, and the shell rotates the rotating sleeve 805 to drive the extension block 1 806 to move. At this time, the fixed column 808 passes through the through hole of the extension block 1 806, so that the extension block 2 807 is separated from the extension block 1 806. At this time, the unwinding roller 802 can be moved by pulling the fixed rod 804. At this time, the paper roll 803 is placed between the two extension frames 801, and the unwinding roller 802 is inserted into the paper roll 803. The extension block 1 806 is rotated by rotating the rotating sleeve 805, so that the extension block 1 806 is fitted with the extension block 2 807, and the installation is completed by rotating the rotation limiting block 809 against the extension block 1 806; At this time, the paper sheets of the paper roll 803 are passed through the two rods at the top of the extension frames 801, passed through the bottom thereof, passed through the top of the adjusting roller 705, passed through the bottom of the limiting roller 204 at the left end, went around to the top of the supporting roller 1 202, passed through the bottom of another limiting roller 204, passed through between the two cleaning rollers 610 and the cooling roller 609 in sequence, passed through between the pressing roller 607 and the positioning roller 608, and finally went around the bottom of the supporting roller 205 and was wrapped around the outside of the winding roller 206; In this process, the second motor 701 is started, and the transmission rod 702 is driven to rotate. The rotation of the transmission rod 702 can drive the rotating plate 703 to rotate. At this time, the rotation of the rotating plate 703 can push the follower plate 704 to swing. The swing of the follower plate 704 drives the adjusting roller 705 to move. Finally, the movement of the adjusting roller 705 can make the sliding block 706 slide on the inner wall of the slide groove 708 and drive the paper sheet at the same time, so as to adjust the tension of the paper sheet, so that the printing roller 203 can better print the paper sheet. After printing is completed, by starting the motor 301, the motor 301 can drive the threaded rod 302 to rotate, and the threaded rod 302 will drive the threaded block 303 to move during rotation. At this time, the movement of the threaded block 303 can drive the dryer 304 to move. The movement of the dryer 304 can dry the printed paper sheets. By adjusting, the different positions of the paper sheets can be dried to improve the drying accuracy. When the threaded rod 302 rotates, it can drive the rotating disk 401 to rotate. At this time, the rotation of the rotating disk 401 can drive the connecting rod 402 to swing. The swing of the connecting rod 402 can drive the rack plate 1 403 to move. When the rack plate 1 403 moves, it can mesh with the gear 2 507 to make the gear 2 507 rotate. At this time, the rotation of the gear 2 507 can drive the rotating rod 502 to rotate. At this time, the rotation of the rotating rod 502 can drive the gear 1 503 to rotate. The gear 1 503 meshes with the rack plate 2 504, so that the rack plate 2 504 can move. The movement of the rack plate 2 504 can drive the embossing block 505 to move, so that the embossing block 505 can realize the embossing operation on the paper sheet. Finally, when the paper sheet passes through the fixed plate 601, the fibers on the surface will be absorbed by the fixed plate 601, and it will be cooled when passing through the cooling roller 609. When passing through the positioning roller 608 and the pressure roller 607, it will be resisted by the pressure roller 607. When the paper sheet passes through the bottom of the pressure roller 607, the pressure roller 607 can drive the support frame 606 to push the cylinder 605 so that the limiting block 604 squeezes the spring 603, thereby causing the spring 603 to deform and generate elastic potential energy. Under the action of the elastic potential energy, the pressure roller 607 can be pushed in the opposite direction to resist the paper sheet, thereby squeezing the paper sheet and preventing the paper sheet from expanding. Finally, after the winding roller 206 collects the paper sheet, the threaded sleeve 207 is rotated to make the threaded sleeve 207 detach from the outside of the winding roller 206. At this time, the winding roller 206 can be taken out to transfer the collected paper sheet.
