[0002] With the improvement of printing technology, the requirements for paper quantity and paper counting speed are getting higher and higher. Especially in the banknote printing industry, the accuracy of paper quantity is not allowed to be inserted incorrectly. For small products (banknotes) that have been printed and cut, they must be counted to confirm the correct quantity when they are handed over manually.

[0003] However, the paper counting machines in the current industry are often used to count larger sheets of paper. For small products that have been printed and cut, many devices cannot count, or the operation is cumbersome, which is not convenient for counting small products. Moreover, the paper counting machines in the printing industry are all large equipment with large size and inconvenient to carry. Even if the equipment can count small products, the products can only be taken to the equipment, which is more troublesome.

[0073] like Figure 4 As shown, a paper tray mounting base plate 30 is fixedly mounted on the base 10, and waist-shaped holes around the paper tray mounting base plate 30 are fixedly connected to the base 10 by bolts. A mounting seat 31 is fixedly connected to the paper tray mounting base plate 30, and a vertical plate 34 is fixedly connected to one side of the mounting seat 31.

[0074] A rotating shaft 32 is supported on the mounting seat 31, and the rotating shaft 32 is installed on the mounting seat 31 through two first bearings 33. One end of the rotating shaft 32 passes through the vertical plate 34 and is fixedly connected to a paper counting turntable 35. A counting module 36 is arranged between the paper counting turntable 35 and the vertical plate 34. The counting module 36 is connected to the negative pressure air supply connector 111 through an air pipe to obtain negative pressure gas when counting papers.

[0075] The working principle of the paper counting turntable 35 and the counting module 36 refers to the Chinese invention patent with publication number CN113361675B and invention name Paper counting assembly and paper counting machine. The paper counting turntable 35 is equivalent to the turntable 10, and the counting module 36 is equivalent to the counting module 20.

The negative pressure sensor 39 on the counting module 36 detects the pressure change to realize counting. In addition, the paper counting turntable 35 has 10 paper separation ports on its circumference. The turntable can count 10 sheets by rotating one circle, which greatly improves the efficiency of counting papers.

[0076] like Figure 3 As shown, the other end of the rotating shaft 32 is connected to a large synchronous wheel 23, and the large synchronous wheel 23 is connected to the small synchronous wheel 21 through a synchronous belt 22. The small synchronous wheel 21 is connected to a servo motor 20, and the servo motor 20 is connected to a servo driver 24 and a control unit 25. The power switch 110 is connected to the servo driver 24 and the control unit 25 to supply power to the servo driver 24 and the control unit 25. The servo motor 20 drives the large synchronous wheel 23 through the small synchronous wheel 21 and the synchronous belt 22, thereby driving the rotating shaft 32 to rotate, thereby driving the paper counting turntable 35 to rotate.

[0077] The vertical plate 34 is provided with a clamping device 38. Figure 5 and Figure 6 As shown, the clamping device 38 comprises a clamping device fixing block 380, and two through holes are provided on the clamping device fixing block 380, into which a movable pin 1 381 and a movable pin 2 382 are inserted respectively. On one side of the clamping device fixing block 380, a connecting strip 2 388 is fixed to the clamping device fixing block 380 by screws 3 387 and 4 389, and on the other side of the clamping device fixing block 380, two ends of a connecting strip 1 384 are fixed to the end faces of the movable pin 1 381 and the movable pin 2 382 respectively by screws 1 383 and 2 386. The two ends of the first tension spring 385 are respectively hooked in the middle of the connecting strip 1 384 and the connecting strip 2 388, and the force of the first tension spring 385 is applied horizontally to the left to the counting module 36 through two movable pins, thereby realizing dynamic sealing between the fixed counting module 36 and the high-speed rotating counting paper turntable 35, providing a solution for dynamic sealing between the non-horizontally installed counting paper turntable and the counting module 16.

[0078] When counting paper, the product needs to move from right to left to complete the counting. Figure 7 and Figure 8 As shown, the paper 42 to be counted is placed on the skateboard table 40, and the base 10 is fixedly mounted with a guide rail 41, and a slider 44 is provided on the guide rail 41. Two second bearings 46 are respectively provided on both sides of the slider 44 as rollers, and the second bearings 46 cooperate with the guide rail 41. The slider 44 moves from right to left on the guide rail 41, and the skateboard table 40 is connected to the slider 44, so that the paper moves from right to left to complete the counting process.

[0079] When the heights of the papers to be counted are different, it is necessary to raise the height of the papers to the same height as the axis of the paper counting turntable 35. Figure 8 and Fig. 9 As shown, the slider 44 is connected to the skateboard deck 40 through four connecting rod mechanisms, and the four connecting rod mechanisms are respectively located at the four corners of the slider 44. The connecting rod mechanism includes a connecting rod 472, and the two ends of the connecting rod 472 are respectively connected to the slider 44 and the skateboard deck 40 through a rotating shaft 473. A second tension spring 471 is installed between the connecting rod 472 and the slider 44 to increase motion damping and improve the stability of the skateboard deck 40 relative to the slider 44.

[0080] The height of the skateboard deck 40 is adjusted by a height adjustment mechanism, such as Fig.10As shown, the height adjustment mechanism includes a height adjustment knob 43, a rotating rod 434 and a cam 45. The height adjustment knob 43 is connected to one end of the rotating rod 434. The rod portion of the rotating rod 434 is provided with the cam 45, and the cam 45 is located below the skateboard deck 40.

[0081] Two support seats 432 are installed on the slider 44 , and both ends of the rotating rod 434 are connected to one of the support seats 432 respectively. The rotating rod 434 can be flexibly rotated on the support seats 432 .

[0082] The cam 45 can be driven to rotate by rotating the height adjustment knob 43 , and the cam 45 lifts up the skateboard surface 40 , thereby achieving the rise of the skateboard surface 40 .

[0083] In order to increase the feel of the height adjustment knob 43 when used and prevent insufficient twisting angle or misoperation, a small pit 433 is processed at the end of the rotating rod 434. The small pit 433 cooperates with the ball-end set screw 431 installed on the support seat 432. The ball-end set screw 431 can increase the rotational resistance of the rotating rod 434 and prevent misoperation.

[0084] The specific operation process is as follows: The paper counting machine is small and flexible and can be placed anywhere it is needed. It only needs to be equipped with a small negative pressure pump for air supply. After the system is powered on, adjust the height of the slide table as needed, place the product, select the counting mode as needed on the LED screen, press the start and stop button, the paper counting turntable starts, and count the small piece of paper from right to left on the slide table with your hand. After the current paper is counted, the slide table slides to the far right, and then you can place new paper to continue counting. Pressing the "Reset" button at any time during the counting process will reset the current count value. For different sizes of paper, the height of the slide table where the product is placed can be adjusted using the height adjustment knob, so that the product can be adjusted to the counting position of the paper counting turntable. After all the paper counting is completed, press the start and stop button again, the button pops up, the paper counting turntable stops rotating, and then the paper counting machine is powered off and air is cut off.

[0085] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
