[0024] Adopting the above scheme: By setting the auxiliary positioning device 5, it is used to position the paper, avoiding the problem that the paper is offset during the printing process and affecting the printing work.

[0025] Referring to Figure 1 , Figure 2 and Figure 3, the pressing assembly 52 includes a positioning rod 521, a limiting block 522, a pressing head 523 and a tension spring 524. The number of positioning rods 521 is three, and they are evenly arranged in the placement groove 51, and the lower ends are fixedly connected to the bottom surface of the placement groove 51. The number of limiting blocks 522 is three, and they are respectively fixedly connected to the upper ends of the three positioning rods 521. The pressing head 523 is sleeved on the upper surfaces of the three positioning rods 521 and is slidably connected to the positioning rods 521 and the limiting blocks 522 respectively. The upper end of the pressing head 523 extends out of the placement groove 51 and is movably connected to the operating table 3. The number of tension springs 524 is three, and they are respectively sleeved on the surfaces of the three positioning rods 521. The upper and lower ends of the three tension springs 524 are respectively fixedly connected to the lower surface of the pressing head 523 and the bottom surface of the placement groove 51.

[0026] With the above solution: By setting the pressing assembly 52, it is used to press and fix both sides of the paper, position the paper, prevent the paper from shifting, and at the same time has the effect of pressing and tightening the paper to a certain extent to avoid the paper from wrinkling.

[0027] Reference Figure 2 and Figure 3 , the linkage assembly 53 includes a connecting member 531 and a pressing plate 532. The connecting member 531 is arranged below one end of the pressing head 523, and the upper end is fixedly connected to the lower surface of the pressing head 523. The pressing plate 532 is fixedly connected to one side of the lower end of the connecting member 531.

[0028] With the above solution: By setting the linkage assembly 53, it is used to drive the pressing assembly 52, and has the function of cooperating with the control assembly 54 to drive the pressing head 523 upward.

[0029] Reference Figure 1 , Figure 2 and Figure 3 , the control assembly 54 includes a rotating rod 541, a pressing wheel 542 and a rotating handle 543. The rotating rod 541 is arranged below the right side of the pressing plate 532, and the front and rear ends are respectively rotatably connected to the front and rear ends inside the placement groove 51.

[0030] With the above solution: By setting the control assembly 54, it is used to drive and control the pressing assembly 52, and has the function of controlling the pressing head 523 to rise to release the fixation of the paper by squeezing the two linkage assemblies 53.

[0031] Reference Figure 2 , Figure 3 and Figure 4, anti-slip pads 6 are fixedly connected to the lower surfaces of the two pressing heads 523 and the upper surface of the operating table 3 directly below the two pressing heads 523.

[0032] Adopting the above solution: by providing anti-slip pads 6 on the lower surfaces of the two pressing heads 523 and the upper surface of the operating table 3 directly below the two pressing heads 523, it has the function of preventing slipping when pressing and fixing both sides of the paper, making the fixation more firm.

[0033] Reference Figure 1 、 Figure 2 and Figure 4 , functional rounded corners 7 are provided at the upper ends of the two sides of the backing plate 4 corresponding to the two auxiliary positioning devices 5.

[0034] Adopting the above solution: by providing functional rounded corners 7 at the upper ends of the two sides of the backing plate 4 corresponding to the two auxiliary positioning devices 5, it has the function of preventing the paper from being tightened and damaged by the edges and corners of both sides of the backing plate 4 when pressing both sides of the paper.

[0035] The working principle of the present utility model:

[0036] During use, the paper is evenly placed flat on the surface of the backing plate 4, and then the rotary handle 543 is rotated clockwise. The rotation of the rotary handle 543 drives the rotating rod 541 to rotate. While the rotating rod 541 rotates, it drives the two pressing wheels 542 to rotate. The pressing wheels 542 rotate clockwise upward to press the lower surface of the pressing plate 532, so that the pressing plate 532 moves upward under the extrusion. The upward movement of the pressing plate 532 pushes the pressing head 523 to move upward on the surface of the positioning rod 521 through the connecting member 531, and at the same time the tension spring 524 will be stretched. After the pressing head 523 rises, at this time, both sides of the paper are placed between the upper end of the pressing head 523 and the upper surface of the operating table 3, and then the rotary handle 543 is rotated counterclockwise, and at the same time the rotary handle 543 is released, so that the pressing wheels 542 no longer press the pressing plate 532. The tension spring 524 will rebound and pull the pressing head 523 downward, pressing both sides of the paper between the anti-slip pad 6 at the upper end of the chuck and the anti-slip pad 6 on the upper surface of the operating table 3. When the two pressing heads 523 press down on both sides of the paper, it can also tighten the paper to a certain extent, making the paper flat, thereby completing the fixation of the paper and preventing deviation.

[0037] In summary, for the paper auxiliary anti-offset device for the printing press, by setting the cooperation of the machine body 1, the printing device 2, the operation table 3, the backing plate 4, the auxiliary positioning device 5, the placement groove 51, the pressing assembly 52, the positioning rod 521, the limit block 522, the pressing head 523, the tension spring 524, the linkage assembly 53, the connecting member 531, the extrusion plate 532, the control assembly 54, the rotating rod 541, the extrusion wheel 542, the rotating handle 543, the anti-slip pad 6 and the functional fillet 7, it solves the problem that the existing flatbed printing press cannot position the paper well when printing the paper to prevent the paper from offsetting, so the paper is very likely to offset during the printing work, directly affecting the printing quality.
