[0002] The electrostatic elimination structure for printing paper is an important part to ensure printing quality and production efficiency, which can significantly reduce the adhesion between papers. During the printing process, static electricity-carrying papers are prone to adsorb and stick to each other, resulting in unsmooth paper feeding and paper jams. The electrostatic elimination structure can avoid this situation, ensure the smooth transmission of papers, and improve printing efficiency.

[0003] After retrieval, the Chinese patent publication number is: CN216610521, an electrostatic elimination device for paper feeding of a printing press, which is used to solve the problems of poor electrostatic elimination effect or relatively high price of the electrostatic elimination device. The device includes a bracket, a winding machine, an electrostatic elimination member, a dust suction member and a slider. The electrostatic elimination member is fixedly arranged at the lower part of the bracket, the winding machine is arranged on the printing press housing at the upper part of the bracket, the dust suction member is arranged inside the bracket, the slider is fixedly connected to the left side of the bracket, and the winding machine is connected to the bracket through a rope. The electrostatic elimination member is composed of a first electrostatic elimination roller arranged on the bracket, a second electrostatic elimination roller arranged on the bracket, and a contact belt wound around the first electrostatic elimination roller and the second electrostatic elimination roller. Through the long-distance contact of the electrostatic elimination member with the paper, the static electricity on the paper can be removed more thoroughly. In addition, the structure of this electrostatic elimination device is simple and the manufacturing cost is low. However, when installing this device, due to the relatively large number of components in the electrostatic elimination part and the relatively cumbersome installation structure, it cannot be flexibly equipped with the existing printing press well, resulting in poor practicability for the existing printing press.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Referring to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present invention: an electrostatic elimination structure for printing paper, including a printing machine (1). Both the left and right ends of the front side of the printing machine (1) are fixedly connected with support rods (3). Two output rotating rollers (4) are fixedly connected between the two adjacent support rods (3). The top end of the front side of the printing machine (1) is fixedly connected with a protective iron plate (5). Both the left and right ends of the front side of the protective iron plate (5) are fixedly connected with magnetic attraction blocks (6). The front ends of the two magnetic attraction blocks (6) are fixedly connected with fixing columns (7). The inner walls of the two fixing columns (7) are rotatably connected with large rotating rings (8). The inner walls of the two large rotating rings (8) are rotatably connected with small rotating rings (9). The adjacent ends of the two small rotating rings (9) are fixedly connected with counterweight lead blocks (10). The adjacent ends of the two counterweight lead blocks (10) are fixedly connected with M buckles (11). The adjacent ends of the two M buckles (11) are fixedly connected with anti-static ropes (12). A winding device (2) is arranged on the right inner wall of the printing machine (1);

[0040] Specifically, magnetic attraction blocks (6) are installed at both ends of the front side of the protective iron plate (5). These magnetic attraction blocks (6) can firmly adsorb on the surface of the protective iron plate (5) to ensure the stability of the whole device. The front ends of the magnetic attraction blocks (6) are connected with fixing columns (7). Large rotating rings (8) are installed inside the fixing columns (7). Small rotating rings (9) are rotatably connected inside the large rotating rings (8). One end of the small rotating ring (9) is connected with a counterweight lead block (10), so that the small rotating ring (9) can naturally hang down under the action of gravity. The M buckle (11) connected to the other end of the counterweight lead block (10) is used to fix the anti-static rope (12). During the discharging process, the printing paper is pushed forward by the output rotating rollers (4). Since the anti-static rope (12) is in contact with the printing paper, the loop formed by the small rotating ring (9) and the large rotating ring 8 can adapt to the swing generated when the printing paper moves forward. At the same time, the counterweight lead block 10 ensures that the anti-static rope (12) is always in contact with the printing paper through its own weight, thereby effectively eliminating the static electricity on the printing paper and enabling the anti-static rope to simply and conveniently solve the problem of static electricity on the paper during the printing process.

[0041] Referring to Figure 1 , Figure 2 and Figure 5, the winding device (2) includes a rotating shaft (201). The left side of the rotating shaft (201) is rotatably connected to a fixed shaft (202). The outer wall of the fixed shaft (202) is rotatably connected to a rotating sleeve (203). A square meshing groove (204) is provided at the left end of the rotating sleeve (203). A rotating motor (205) is fixedly installed on the inner bottom wall of the left side of the printing machine (1). The right end of the rotating motor (205) is fixedly connected to a square rotating head (206). Fixed pins (207) penetrate through the front sides of the rotating sleeve (203) and the square rotating head (206);

[0042] Specifically, after the printing machine (1) finishes printing the printing paper, after manually fixing one end of the printing paper on the rotating sleeve (203), start the rotating motor (205) to make the square rotating head (206) rotate. Since the square meshing groove (204) provided at the left end of the rotating sleeve (203) meshes with the square rotating head (206), the rotating sleeve (203) will also rotate synchronously. At the same time, the printing paper is gradually wound on the rotating sleeve (203). When it is necessary to install or remove the rotating sleeve (203), only need to insert and pull out the fixed pin (207) so that it no longer fixes the square rotating head (206) and the rotating sleeve (203), and then easily remove the rotating sleeve (203) from the fixed shaft (202). This increases the winding efficiency of the printing paper and ensures the stability and accuracy of rotation, thus realizing the stable winding of the printing paper.

[0043] Refer to Figure 2 and Figure 3 , two storage cabinets (13) are fixedly connected to the right side of the printing machine (1). Handles (14) are fixedly installed on the right sides of the two storage cabinets (13); A horizontal frame (15) is fixedly connected to the middle of the top wall of the printing machine (1). A plurality of spirit levels (16) are fixedly installed on the inner wall of the horizontal frame (15); Columns (17) are fixedly connected to the four corners of the bottom wall of the printing machine (1). Anti-slip pads (18) are fixedly connected to the bottoms of the plurality of columns (17);

[0044] Specifically, the storage cabinet (13) is used to store various items required during the printing process. The handle (14) makes it more convenient to open and close the storage cabinet 13. The horizontal frame (15) provides a platform for supporting and fixing the spirit level (16) to ensure that the printing machine (1) remains horizontal during the working process, thereby improving the printing quality. The columns (17) provide support for the entire printing machine 1. The anti-slip pads (18) at the bottom prevent the printing machine (1) from shaking and causing displacement during the working process, ensuring the accuracy and safety of the printing operation.

[0045] Refer to Figure 2 and Figure 5, a control console (19) is fixedly connected to the middle of the left side of the printing press (1), and a plurality of control buttons (20) are fixedly installed on the top of the control console (19); a tachometer (21) is fixedly connected to the upper middle part of the left side of the printing press (1), and a scale pointer (22) is arranged on the left side of the tachometer (21); a heat sink (23) is fixedly installed at the rear end of the left side of the printing press (1), and limiting rings (24) are fixedly connected to both the left and right ends of the outer wall of the rotating sleeve (203);

[0046] Specifically, as an integrated device for all operation functions, the control buttons (20) on the top of the control console (19) can turn on, turn off and adjust the speed of the printing press 1. The tachometer (21) and the scale pointer (22) are used to display the speed of the printing press (1) to help the operator understand the operating state of the machine. The heat sink (23) is responsible for reducing the heat generated by the printing press (1) during operation. The limiting rings (24) are used to fix the position of the printed paper on the rotating sleeve (203) during the winding process to prevent it from shifting during the winding process.

[0047] Working principle: Magnetic absorption blocks (6) are installed at both ends of the front side of the protective iron plate (5). These magnetic absorption blocks (6) can firmly adsorb on the surface of the protective iron plate (5) to ensure the stability of the entire device. The front end of the magnetic absorption block (6) is connected to a fixed column (7). A large rotating ring (8) is installed inside the fixed column (7). A small rotating ring (9) is rotatably connected inside the large rotating ring (8). One end of the small rotating ring (9) is connected to a counterweight lead block (10), so that the small rotating ring (9) can naturally hang down under the action of gravity. The M buckle (11) connected to the other end of the counterweight lead block (10) is used to fix the anti-static rope (12). During the discharging process, the printed paper is pushed forward by the output rotating roller (4). Since the anti-static rope (12) is attached to the printed paper, the loop formed by the small rotating ring (9) and the large rotating ring 8 can adapt to the swing generated when the printed paper moves forward. At the same time, the counterweight lead block 10 ensures that the anti-static rope (12) is always attached to the printed paper through its own weight, thereby effectively eliminating the static electricity on the printed paper.

[0048] And after the printing press (1) finishes printing the printed paper, after manually fixing one end of the printed paper on the rotating sleeve (203), start the rotating motor (205) to make the square rotating head (206) rotate. Since the square engaging groove (204) opened at the left end of the rotating sleeve (203) meshes with the square rotating head (206), the rotating sleeve (203) will also rotate synchronously. At the same time, the printed paper is gradually wound on the rotating sleeve (203). When it is necessary to install or disassemble the rotating sleeve (203), just insert and remove the fixed pin (207) so that it no longer fixes the square rotating head (206) and the rotating sleeve (203), and then the rotating sleeve (203) can be easily removed from the fixed shaft (202).

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
