Technical Field

[0001] The present application relates to the field of paper printing, and in particular to a paper printing device. Background Art

[0002] A printing press is a mechanical device that presses the inked surface onto the media surface. Modern printing presses are generally composed of mechanisms such as plate loading, inking, pressing, and paper feeding. The printing press applies ink to the areas with text and images on the plate, and then directly or indirectly transfers it to paper or other substrates, thereby reproducing printed products that are identical to the plate. The invention and development of the printing press has played an important role in the spread of human civilization and culture.

[0003] For example, the paper printing device of patent number CN201921667703.4 has the following deficiencies in actual use:

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] The embodiment of the present application discloses a paper printing device.

[0038] Example 1

[0039] Reference Figure 1 A paper printing device includes a supporting mechanism 1 and a supporting mechanism 2, wherein the supporting mechanism 22 is located directly above the supporting mechanism 1 and has the same structural dimensions. Support feet are fixedly provided at the four corners of the lower end of the anti-pressure platform 102 of the supporting mechanism 1 by bolts. Threaded holes can be provided at the lower ends of the support feet and then fixed to the ground by bolts. The anti-pressure platform 102 is configured as a metal platform with a certain rigidity to prevent the rubbing head 9 from being deformed by being pressed down, thereby affecting the printing effect of the paper. At the same time, the device also includes a paper conveying device and a winding device, which are not described in detail because they are not the main technologies. It should be noted that the servo motor 8 of the device needs to cooperate with the conveying device and the winding device outside the device to achieve precise movement of the paper on the anti-pressure platform 102.

[0040] Reference Figure 1 , 2 The supporting mechanism 2 includes rectangular columns 3 welded to the middle of both sides of the outer surface of the pressure-resistant platform 102, and the upper ends of the two columns 3 are welded to both sides of the outer surface of the pressure-resistant platform 102 of the supporting mechanism 1 on the opposite sides.

[0041] The two upright columns 3 provided above can fix the supporting mechanism 1 and the supporting mechanism 2 2 to form a frame, thereby realizing the basic structure of the printing device, which is convenient for the subsequent installation of other components.

[0042] Reference Figure 1-4 A rectangular fixing frame 4 is welded to the middle of the two columns 3 facing each other. The structure of the fixing frame 4 (such as Figure 4 As shown in the figure, the crankshaft 5 includes structures such as a main bearing journal, a crank, a counterweight and a crank pin journal. The main bearing journals at both ends of the crankshaft 5 are movable and penetrate the openings on both sides of the fixed frame 4, and the main bearing journals extend to the outside of the fixed frame 4. The mounting end of the servo motor 8 is fixed to the surface of the fixed frame 7 by bolts. The output shaft of the servo motor 8 is movable and penetrates the side wall of the fixed frame 7. The output shaft of the servo motor 8 is fixed to one end of the crankshaft 5 by a coupling to achieve transmission. The fixed frame 7 is set to be "U" shaped.

[0043] Through the above arrangement, the external control computer transmits signals to the compiler through wires to energize the servo motor 8 to work. The servo motor 8 drives the main bearing journal of the crankshaft to rotate through the coupling to drive the crankshaft 5 to rotate, thereby realizing power transmission.

[0044] Reference Figure 2-5 The crankpin journal of the crankshaft 5 movably passes through one end of the connecting rod 6, and the other end of the connecting rod 6 movably passes through a rotating shaft. The rotating shaft and the inner wall of the slot at the upper end of the rubbing head 9 are rotatably arranged on both sides and drive the rubbing head 9 to move longitudinally. It should be noted that for the convenience of installation, one end of the connecting rod 6 can be installed in the same way as the crankshaft 5 and the connecting rod of the existing automobile engine, and can be installed by bolts to facilitate later maintenance. Therefore, the setting needs to be set according to the actual situation of the device. The upper and middle lower parts of the column 3 are fixed to the two sides of the outer surface of the limit frame 101, and the fixed frame 4 is located in the middle between the two limit frames 101. The limit frame 101 is evenly spaced and has a plurality of rectangular limit openings 101. 3. The size of the limit opening 103 matches the size of the rubbing head 9. Multiple rubbing heads 9 are all movable longitudinally in the limit opening 103. Multiple rubbing heads 9 are all set to be trapezoidal. The rubbing surface of the rubbing head 9 is located on one side of the pressure-resistant platform 102. It should be noted that the rubbing head 9 is the same as the existing company seal, and paint is arranged inside it. At the same time, a feed pipe for providing paint is also arranged outside the shell of the rubbing head 9. The feed pipe is connected to an external paint supply device. The outer wall of the rubbing head 9 abuts against the inner wall of the limit opening 103 and slides. The height of the limit opening 103 is much larger than the distance moved by the rubbing head 9 in one stroke, so that the rubbing head 9 is always located inside the limit opening 103 to achieve limiting.

[0045] Through the above arrangement, each crankpin journal on the surface of the crankshaft 5 is rotatably provided with a connecting rod 6, so when the crankshaft 5 rotates, the rubbing head 9 moves longitudinally in the limit frame 101 through the connecting rod 6. Figure 5 As shown, the rubbing surface of the rubbing head 9 will just fit against the paper and print. During this process, the connecting rod 6 of the device will swing in the limit opening 103. Each rubbing head 9 can be set with different printing contents or patterns and colors, and then coordinated by the distance the paper moves, so that the paper can be printed successfully at one time. The crankshaft 5 drives the rubbing head 9 to move back and forth to achieve the effect of continuous printing.

[0046] At the same time, the size of the rubbing head 9 can be set according to the length of the crank pin journal. The longer the length of the crank pin journal, the larger the rubbing head 9 and the larger the printing area. At the same time, the column 3 can also be replaced with an electric push rod, which can adjust the degree of pressure between the rubbing head 9 and the paper in real time.

[0047] The implementation principle of a paper printing device in an embodiment of the present application is: when the paper is located on the surface of the anti-pressure platform 102 of the supporting mechanism 1 and the surface of the anti-pressure platform 102 of the supporting mechanism 2 and stops moving, then the servo motor 8 drives the crankshaft 5 to rotate, the crankshaft 5 drives the connecting rod 6 to move and then drives the rubbing head 9 to move longitudinally in the limit opening 103. This structure is similar to the action mode of the piston of an engine, thereby realizing the printing of paper.

[0048] In summary, the use of the supporting mechanism 1 and the supporting mechanism 2 2 can effectively improve the efficiency of paper printing, and two printing lines can be set on the same device. At the same time, the device can complete the printing of different patterns at one time.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
