[0044] Embodiment 2

[0045] In the above embodiment, the printing control instrument body 1 will produce turbulence or displacement when working, and the stamping process is likely to cause the position of the stamping operation to shift due to the turbulence or displacement of the printing control instrument body 1, making it difficult to stamp smoothly, which is not conducive to improving the stamping effect, and is likely to cause the paper to be scrapped or need to be re-stamped, which is not conducive to improving work efficiency;

[0046] like Figure 1 and Figure 8As shown, the difference between this embodiment and embodiment 1 is that an auxiliary stabilizing mechanism 2 is fixedly arranged at the bottom of the printing control instrument body 1, and the control display panel 10 controls the connection of the auxiliary stabilizing mechanism 2 to facilitate the control of the staff. The auxiliary stabilizing mechanism 2 includes a printing control instrument bearing plate 21, which is fixedly arranged at the bottom of the printing control instrument body 1 to support the printing control instrument body 1, and rubber adsorption disks 22 are fixedly arranged at multiple positions at the bottom of the printing control instrument bearing plate 21. A central chamber 23 is opened at the inner center of the printing control instrument bearing plate 21, and multiple groups of opening and closing branch pipes 24 are installed in the printing control instrument bearing plate 21.

[0047] In the specific working process, when it is necessary to keep the printing control instrument body 1 stable, the solenoid valves on each group of opening and closing branch pipes 24 are opened and the solenoid valve on the connecting pipe 26 is closed, and the gas in the central chamber 23 is extracted through the negative pressure main pipe 25 to make the interior of the central chamber 23 in a negative pressure state, thereby extracting the gas in each group of rubber adsorption discs 22 through each group of opening and closing branch pipes 24, and each group of rubber adsorption discs 22 is in a negative pressure state to be tightly adsorbed on the table surface. At this time, the solenoid valves on each group of opening and closing branch pipes 24 are closed to achieve effective fixation of the printing control instrument body 1, ensure the stability of the working process of the printing control instrument body 1, avoid turbulence or displacement of the printing control instrument body 1 during the stamping process, and play an auxiliary and promoting role in improving the stamping effect; when it is necessary to move the printing control instrument body 1, the solenoid valves on each group of opening and closing branch pipes 24 and the solenoid valve on the connecting pipe 26 are opened, and the external air gradually enters each group of rubber adsorption discs 22 to restore the interior to a normal pressure state. At this time, the rubber adsorption discs 22 no longer adsorb the table surface, and the staff can move the printing control instrument body 1.

[0048] Embodiment 3

[0049] like Figure 1 and Figure 9-10As shown, the difference between this embodiment and embodiment 1 and embodiment 2 is that the control display panel 10 controls the connection of the paper anti-displacement mechanism 8, and the paper anti-displacement mechanism 8 is installed on both sides of the stamping platform 7.

[0050] During the working process, when the placement and adjustment of the paper on the stamping platform 7 is completed, the two groups of horizontal adjustment electric cylinders 83 are started and the X-axis position of the electric cylinder mounting seat 811 is adjusted, and the two groups of lifting electric cylinders 84 are started and the height of the lower pressing bar 87 is adjusted until the two groups of lower pressing bars 87 press the upper part of both sides of the paper to prevent the paper from being displaced during the stamping process, and help to keep the paper on the stamping platform 7 flat, thereby ensuring the stamping effect and stamping efficiency. Preferably, a rubber anti-slip pad 88 is fixedly arranged at the bottom of the lower pressing bar 87 to prevent imprinting on the paper surface when pressing down, and to help improve the pressing and fixing effect.

[0051] Embodiment 4

[0052] like Fig.10 As shown, the difference between this embodiment and Embodiment 1, Embodiment 2 and Embodiment 3 is that the top end of the vertical downward pressure rod 86 extends upward into the vertical extrusion cylinder 85, a connecting block 89 is slidably arranged in the vertical extrusion cylinder 85, and the top end of the vertical downward pressure rod 86 is fixedly connected to the connecting block 89, a connecting spring 810 is fixedly arranged on the inner top wall of the vertical extrusion cylinder 85, and the bottom end of the connecting spring 810 is fixedly connected to the top of the corresponding connecting block 89; when the two groups of lower pressure strips 87 press down on the top two sides of the paper, the connecting spring 810 is in a compressed state and applies downward pressure to the connecting block 89, thereby applying downward pressure to the lower pressure strip 87 through the vertical downward pressure rod 86, which helps to make the lower pressure strip 87 tightly press the top two sides of the paper.

[0053] The working process and principle of the present invention are as follows:

[0054] When in use, the paper conveying roller 41 in the paper conveying mechanism 4 rotates, and the paper conveying belt 42 conveys the printed paper into the printing control instrument body 1 to realize the automatic input of the paper. During the paper input process, the negative pressure pump 64 in the conveying adsorption mechanism 6 is started, and the adsorption tube 65 is evacuated. Each group of negative pressure suction nozzles 63 sucks air from the lower part of the upper paper conveying belt 42. The lower part of the paper conveyed on the paper conveying belt 42 is in a negative pressure state. Under the action of the adsorption hole 44, the paper is attached to the paper conveying belt 42, which effectively prevents the position of the paper from being offset or falling from the paper conveying belt 42 during the paper conveying process, thereby ensuring the smooth and stable transportation of the paper. There is no need to manually deliver the paper to be stamped into the printing control instrument body 1. The operation is simple and convenient, the operation steps are simplified, and the work efficiency is improved; when the paper is about to enter the printing control instrument body 1, the lower pressure roller 52 in the paper wrinkle removal mechanism 5 is subjected to downward pressure, and the paper passes between the lower pressure roller 52 and the upper supporting roller 51, and the paper is stretched out by the squeezing and conveying of the upper supporting roller 51 and the lower pressure roller 52, so as to ensure that the paper is spread out flat, and the adverse effect on the stamping process caused by wrinkles or folds on the surface of the paper is avoided, thereby improving the stamping effect; and by adjusting the height of the mounting block 54 by adjusting the electric cylinder 55, the pressure applied by the lower pressure roller 52 to the paper below changes, so as to realize the adjustment of the downward pressure, and the pressure sensor 58 performs pressure detection during the adjustment process, which is convenient for adjustment and helps to improve the adjustment accuracy;

[0055] The paper enters the printing control instrument body 1 and falls to the upper end surface of the stamping platform 7. The paper scanner 11 scans and determines whether the paper on the upper end surface of the stamping platform 7 is offset. When the paper is offset, the conveying roller 92 in the position adjustment and delivery mechanism 9 rotates, and the position adjustment conveyor belt 91 moves accordingly to adjust the position of the paper on the upper end surface of the stamping platform 7 until the front and rear sides of the paper are flush with the X-axis; after the adjustment is completed, the two sets of paper anti-displacement mechanisms 8 press the upper sides of the paper to prevent the paper from being displaced during the stamping process and keep the paper flat, and the adjustable stamping device 12 can stamp the stamping area on the paper; after the stamping is completed, the paper anti-displacement mechanism 8 releases the paper on the upper end surface of the stamping platform 7, and the conveying roller 92 in the position adjustment and delivery mechanism 9 continues to move, and the paper on the upper end surface of the stamping platform 7 moves outward and falls into the paper collection box 13, so as to realize the collection of stamped paper, thereby improving the automation and intelligence of the equipment.
