Description

Technical Field

[0001] This utility model relates to the technical field of paper flipping mechanism, and more particularly to a paper flipping mechanism. Background Technology

[0002] In the paper printing process, after one side is printed, the reverse side needs to be printed. During the paper flipping process, it is usually done manually. However, manual flipping may result in errors, such as leaving unflipped pages, contaminating and damaging the paper, which seriously affects printing efficiency.

[0003] Existing paper-turning machines suffer from problems such as long conveying paths, complex structures, and large equipment sizes. The pressure and friction generated by the alternating flipping of the paper using rollers can easily damage the paper. To overcome these disadvantages, this invention provides a paper-turning mechanism. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a paper flipping mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a paper flipping mechanism, comprising a base, a support rod fixedly connected to the top of the base, a movable block fixedly connected to the front side of the support rod, a groove formed on the front side of the movable block, a threaded rod rotatably connected inside the groove, a power component provided at one end of the threaded rod, a slider slidably connected inside the groove, a reduction motor fixedly connected to the top of the slider, a rotating rod fixedly connected to the output end of the reduction motor, a first fixed plate fixedly connected to the other end of the rotating rod, a flipping component provided on the front side of the first fixed plate, a support column fixedly connected to the top of the base, an isolation plate fixedly connected to the top of the support column, and a rotating component provided at the top of the isolation plate.

[0007] Furthermore, a first support block is fixedly connected to the front end of the slider, and a support hole frame is fixedly connected to the top end of the first support block. The support hole frame and the rotating rod are rotatably connected.

[0008] Furthermore, the power assembly includes a passive gear fixedly connected to the right end of the threaded rod, a high-speed motor fixedly connected to the right side of the top of the base, a driving gear fixedly connected to the output end of the high-speed motor, and the driving gear and the passive gear are driven by a chain.

[0009] Furthermore, the flipping assembly includes a first adsorption plate fixedly connected to the front side of the first fixed plate, a fixed block fixedly connected to the bottom end of the first adsorption plate, a first electric telescopic rod fixedly connected to the fixed block, a telescopic frame opened in the middle of the first adsorption plate, a second adsorption plate fixedly connected to the output end of the first electric telescopic rod, a second fan hole opened at the top of the second adsorption plate, a second straight-tube exhaust fan fixedly connected to the second fan hole, and first fan holes opened at the top of the first adsorption plate and on both sides of the telescopic frame, with a first straight-tube exhaust fan fixedly connected to the first fan hole.

[0010] Furthermore, the rotating assembly includes a servo motor fixedly connected to the top of the isolation plate, a second support block fixedly connected to the output end of the servo motor, a telescopic hole opened on one side of the second support block, a second electric telescopic rod fixedly connected to the telescopic hole, a second fixed plate fixedly connected to the output end of the second electric telescopic rod, a third adsorption plate fixedly connected to the front end of the second fixed plate, a third adsorption hole opened on the third adsorption plate, and a third straight-tube exhaust fan fixedly connected to the third adsorption hole.

[0011] The beneficial effects of this utility model are:

[0012] In use, this paper-flipping mechanism works as follows: First, a high-speed motor moves a slider to the area where the paper will be flipped. Then, a reduction motor flips the first suction plate so that its suction surface faces the paper. Next, a first electric telescopic rod moves the second suction plate to the area where the paper will be flipped. The second straight-tube exhaust fan is then activated to initially suction the paper. After the paper is suctioned, the first electric telescopic rod is activated again to retract the second suction plate. Then, the first straight-tube exhaust fan is activated again to suction the paper a second time. Then, the reduction motor is rotated again to turn the suction surface upwards, and the slider is moved again to transfer the paper to the third suction plate. The first electric telescopic rod is activated again to bring the second and third suction plates into contact. At this point, the third straight-tube exhaust fan is activated, and the second straight-tube exhaust fan is turned off. Afterward, a servo motor rotates to move the paper to other processing areas.

The driving gear (503) and the passive gear (501) are driven by a chain (502) to provide power for the rotation of the threaded rod (5).

[0024] like Figure 1-3 As shown, the flipping assembly includes a first adsorption plate (12) fixedly connected to the front side of the first fixed plate (11), a fixed block (13) fixedly connected to the bottom end of the first adsorption plate (12), a first electric telescopic rod (30) fixedly connected to the fixed block (13), a telescopic frame (14) opened in the middle of the first adsorption plate (12), a second adsorption plate (17) fixedly connected to the output end of the first electric telescopic rod (30), a second fan hole (18) opened at the top of the second adsorption plate (17), a second straight-tube exhaust fan (19) fixedly connected to the second fan hole (18), a first fan hole (15) opened at the top of the first adsorption plate (12) and on both sides of the telescopic frame (14), a first straight-tube exhaust fan (16) fixedly connected to the first fan hole (15) for adsorbing and flipping the paper.

[0026] Working principle: In use, firstly, the reduction motor 7 is started, and through the rotating rod 9 and the first fixed plate 11, the adsorption surface of the first adsorption plate 12 is positioned downwards towards the paper to be adsorbed. Then, the high-speed motor 504 is started, which drives the driven gear 501 to rotate through the chain 502 on the driving gear 503, thereby driving the threaded rod 5 to rotate, so that the slider 6 moves to the position above the paper to be adsorbed.

When the second adsorption plate 17 reaches the telescopic frame 14, the first straight-tube exhaust fan 19 is started. The blower 16 performs a secondary adsorption of the paper. Then, the geared motor 7 starts again to turn the adsorption surface of the first adsorption plate 12 upward. After that, the high-speed motor 504 starts again and moves the slider 6 so that the first adsorption plate 12 is above the third adsorption plate 27. After reaching the third adsorption plate 27, the first straight-tube exhaust fan 16 is turned off and the first electric telescopic rod 30 is started so that the paper that has been turned over on the adsorption surface of the second adsorption plate 17 comes into contact with the adsorption surface of the third adsorption plate 27. Then, the third straight-tube exhaust fan 29 starts to adsorb the paper. The second straight-tube exhaust fan 19 is turned off and the first electric telescopic rod 30 is started again to retract the second adsorption plate 17. Then, through the servo motor 22 above the isolation plate 21 and the second electric telescopic rod 25, the paper on the third adsorption plate 27 is moved to other areas to be processed.
