[0002] Paper counting machine is a paper counter that counts the paper feed through mechanical or photoelectric sensors. Paper counting machines are commonly used in the printing industry. Before paper counting machines were introduced, paper was counted manually or weighed on a scale to estimate the number of papers. Therefore, the emergence of paper counting machines has greatly improved the efficiency of paper counting while also ensuring the accuracy of the paper counting value.

[0003] At present, most of the paper counting machines on the market use complex mechanical structures and electronic control systems. Although they count accurately, they are bulky and not only take up a lot of space but are also inconvenient for users to move. Summary of the invention

[0006] By adopting the above technical solution, when using, the paper counting machine is placed in a suitable position. The user only needs to place the paper on the bottom plate, adjust the pressing component to press the paper, and then start the moving component and the paper counting component. The moving component moves the numerical component to a suitable position first. The moving component drives the paper counting component to move in the vertical direction, and the paper counting component pushes the paper one by one, while the counter counts accurately.

[0008] By adopting the above technical solution, the first motor is started, and the first motor drives the lead screw to rotate, and the lead screw enables the mounting frame to move in the vertical direction. At the same time, the mounting frame and the mounting cover are slidably abutted to ensure the stability and accuracy of its movement. The paper counting assembly is connected to the mounting frame and moves with the mounting frame, thereby realizing the operation of moving the paper.

[0009] Preferably, the paper counting assembly includes a second motor, a rotating shaft and a paper counting roller, the second motor is connected to the mounting frame, the rotating shaft is horizontally arranged, both ends of the rotating shaft are rotatably connected to the mounting member, one end of the rotating shaft is connected to the second motor, the paper counting roller is sleeved on the rotating shaft and fixedly connected to the rotating shaft, and the paper counting roller can abut against the paper to be counted.

[0010] By adopting the above technical solution, the second motor is started, and the second motor drives the rotating shaft and the paper counting roller to rotate. During the paper counting process, the paper counting roller can abut against the paper to be counted and push the paper away by rotating.

[0011] Preferably, the mounting frame is connected to a first limiting plate, which is rotatably connected to the mounting frame via a first shaft rod, and the first limiting plate is inserted between the counted paper and the paper to be counted, and can limit the counted paper, and the first shaft rod is connected to a driving component that drives the first limiting plate to rotate.

[0012] By adopting the above technical solution, the first limiting piece limits the counted paper, reducing the possibility of repeated counting of paper. The driving component realizes the rotation of the first limiting piece, improving the efficiency of counting paper.

[0013] Preferably, the mounting frame is connected to a second limiting plate, the second limiting plate is rotatably connected to the mounting frame via a second shaft, the first limiting plate is inserted between the counted paper and the paper to be counted, the second limiting plate is connected to the driving component, and the driving component can make the second limiting plate and the first limiting plate move alternately to limit the counted paper in turn.

[0014] By adopting the above technical solution, the second limiting piece can also limit the paper that has been counted. During the paper counting process, the driving component causes the second limiting piece to move alternately with the first limiting piece, thereby limiting the paper that has been counted in sequence. This design not only ensures the accuracy of paper counting, but also further reduces the confusion and misalignment of paper.

[0015] Preferably, the driving assembly includes a cylinder, a rack, a first gear and a second gear, the cylinder is connected to the top of the mounting cover, and its driving shaft is connected to the rack; a vertically arranged first groove is provided on the side wall of the first shaft rod, the mounting cover is rotatably connected to a first sleeve, the first sleeve is connected to a first protrusion that cooperates with the first groove, the first shaft rod is sleeved in the first sleeve, and the first gear is sleeved in the first sleeve; a vertically arranged second groove is provided on the side wall of the second shaft rod, the mounting cover is rotatably connected to a second sleeve, the second sleeve is connected to a second protrusion that cooperates with the second groove, the second shaft rod is sleeved in the second sleeve, the second gear is sleeved in the second sleeve, and the rack is meshed with the first gear or the second gear.

[0016] By adopting the above technical solution, the rack moves linearly under the drive of the cylinder, and the rack meshes with the first gear or the second gear during the movement. The rotation of the first gear drives the first sleeve to rotate, and the rotation of the second gear drives the second sleeve to rotate. Since the first shaft rod and the second shaft rod are connected by the first groove and the first protrusion, the first sleeve can not only make the first shaft rod move in the vertical direction to ensure the normal movement of the mobile frame, but also drive the first shaft rod to rotate. Since the second shaft rod and the second shaft rod are connected by the second groove and the second protrusion, the second sleeve can not only make the second shaft rod move in the vertical direction to ensure the normal movement of the mobile frame, but also drive the second shaft rod to rotate. Therefore, the cylinder drives the rack to reciprocate, and then makes the first gear or the second gear to reciprocate, so that the first limit piece or the second limit piece is immediately reset after rotation. Every time the paper counting roller pushes the paper away, the paper will be bent by force, and the first limit piece or the second limit piece is rotated and reset, and can be inserted when the paper is bent, so as to achieve the limit of the paper that has been counted.

[0017] Preferably, the drive assembly further includes a first torsion spring, which is sleeved on the first sleeve and located between the first gear and the mounting cover, wherein a first end of the first torsion spring is connected to the mounting cover, and a second end of the first torsion spring is connected to the first sleeve.

[0018] By adopting the above technical solution, when the rack is disengaged from the first gear, the first torsion spring prevents the first sleeve from rotating automatically, thereby keeping the first gear in position unchanged, making it easier for the rack to mesh with the first gear again.

[0019] Preferably, the drive assembly further includes a second torsion spring, which is sleeved on the second sleeve and located between the second gear and the mounting cover, wherein a first end of the second torsion spring is connected to the mounting cover, and a second end of the second torsion spring is connected to the second sleeve.

[0021] Preferably, the counter is electrically connected to a control module, the control module is electrically connected to both the first motor and the second motor, the control module is electrically connected to a display, and the display is arranged on the top of the top plate for displaying the number of papers.

[0022] By adopting the above technical solution, during the paper counting process, the control module controls the start and stop and the rotation speed of the first motor and the second motor according to the preset program. This enables the paper counting roller to push the paper at a suitable speed and ensure that only one paper is pushed at a time. At the same time, the control module also receives the counting signal of the counter in real time and displays the counting result on the display. In this way, the user can intuitively understand the current number of papers, so as to more conveniently perform subsequent operations.

[0023] Preferably, the clamping assembly includes a screw, a turntable and a pressure rod, the screw is threadedly connected to the top plate, the turntable is located above the top plate and fixedly connected to the top end of the screw, and the pressure rod is rotatably connected to the bottom end of the screw and is parallel to the bottom plate.

[0024] By adopting the above technical solution, when in use, the turntable is rotated according to the thickness of the paper, so that the screw drives the height of the pressure rod to a suitable position. Then, the paper is placed on the bottom plate, and one corner of the paper is suspended in the air. Then, the pressure rod presses the paper tightly on the bottom plate, reducing the possibility of the paper moving during the counting process.

[0025] In summary, the present invention has the following beneficial effects: 1. When using, place the paper counting machine in a suitable position. The user only needs to place the paper on the bottom plate, adjust the pressing component to press the paper, and then start the moving component and the paper counting component.

[0039] When in use, the rotating disk 32 is rotated according to the thickness of the paper, so that the screw 31 drives the pressure rod 33 to a suitable height. Then, the paper is placed on the bottom plate 1, and one corner of the paper is suspended in the air. Then, the pressure rod 33 presses the paper against the bottom plate 1 to reduce the possibility of the paper moving during the counting process.

[0040] Reference Figure 1 The mounting cover 4 is in a rectangular parallelepiped shape and is transparent. The mounting cover 4 is fixedly connected to both the first baffle 13 and the second baffle 14. The top of the mounting cover 4 is flush with the top plate 2 and is fixedly connected to the top plate 2.

[0041] Reference Figure 3 The moving assembly 51 includes a first motor 511, a lead screw 512 and a mounting bracket 513. The first motor 511 is fixedly connected to the top of the mounting cover 4. The first motor 511 and the lead screw 512 form a driving group, and two driving groups are provided, and the two driving groups are arranged at intervals. The driving shaft of the first motor 511 passes through the mounting cover 4 and is fixedly connected to the lead screw 512. The lead screw 512 is vertically arranged in the mounting cover 4, and the lead screw 512 is rotatably connected to the bottom of the mounting cover 4.

[0042] Reference Figure 3 The mounting frame 513 is C-shaped, and its opening faces the bottom plate 1. The mounting frame 513 is sleeved on the two lead screws 512 and is threadedly connected to the two lead screws 512. The outer wall of the mounting frame 513 is in sliding contact with the inner wall of the mounting cover 4.

[0043] The first motor 511 is started, and the first motor 511 drives the lead screw 512 to rotate, and the lead screw 512 enables the mounting frame 513 to move in the vertical direction. At the same time, the mounting frame 513 is in sliding contact with the mounting cover 4, ensuring the stability and accuracy of its movement.

[0044] Reference Figure 3 The paper counting assembly 52 includes a second motor 521, a rotating shaft 522 and a paper counting roller 523. The rotating shaft 522 is horizontally arranged in the opening of the mounting frame 513 and is rotatably connected to the mounting frame 513. The second motor 521 is semi-embedded on the mounting frame 513, and its driving shaft is fixedly connected to one end of the rotating shaft 522. The paper counting roller 523 is sleeved on the rotating shaft 522, and the top of the paper counting roller 523 is higher than the top of the mounting frame 513.

[0045] The second motor 521 is started, and the second motor 521 drives the rotating shaft 522 and the paper counting roller 523 to rotate. During the paper counting process, the paper counting roller 523 can abut against the paper to be counted and push the paper away by rotating.

[0046] Reference Figure 2 and Figure 3 The counter 6 is arranged inside the mounting frame 513 , and the counter 6 is electrically connected to a control module, and the control module is electrically connected to both the first motor 511 and the second motor 521 . The control module is electrically connected to a display 61 .

[0047] During the paper counting process, the control module controls the start and stop of the first motor 511 and the second motor 521 and the speed according to the preset program. This enables the paper counting roller 523 to push the paper at a suitable speed and ensure that only one paper is pushed at a time. At the same time, the control module also receives the counting signal of the counter 6 in real time and displays the counting result on the display 61. In this way, the user can intuitively understand the current number of papers, so as to more conveniently perform subsequent operations.

[0048] Reference Figure 3 and Figure 4 The first free end of the mounting frame 513 is provided with a first limiting piece 7. The first limiting piece 7 is connected to a first shaft 71, which is vertically arranged, and the bottom end of the first shaft 71 passes through the first limiting piece and is rotatably connected to the mounting frame 513, the first shaft 71 is fixedly connected to the first limiting piece 7, and the top end of the first shaft 71 passes through the top of the mounting cover 4.

[0049] Reference Figure 4 The first shaft rod 71 is provided with a first groove 711, and the first groove 711 is vertically arranged. The first shaft rod 71 is sleeved with a first sleeve 72, and the inner wall of the first sleeve 72 is fixedly connected with a first protrusion 721, and the first protrusion 721 matches the first groove 711. The first shaft rod 71 is slidably connected with the first sleeve 72. The first sleeve 72 is rotatably connected with the outer top surface of the mounting cover 4.

[0050] Since the first shaft 71 and the second shaft 81 are clamped together by the first groove 711 and the first protrusion 721 , the first sleeve 72 can not only enable the first shaft 71 to move in the vertical direction to ensure the normal movement of the moving frame, but also drive the first shaft 71 to rotate.

[0051] Reference Figure 3 and Figure 4 The second free end of the mounting frame 513 is provided with a second limiting piece 8. The second limiting piece 8 is connected to a second shaft rod 81, which is vertically arranged, and the bottom end of the second shaft rod 81 passes through the second limiting piece and is rotatably connected to the mounting frame 513, and the second shaft rod 81 is fixedly connected to the second limiting piece 8, and the top end of the second shaft rod 81 passes through the top of the mounting cover 4.

[0052] Reference Figure 4 The second shaft rod 81 is provided with a second groove 811, and the second groove 811 is vertically arranged. The second shaft rod 81 is sleeved with a second sleeve 82, and the inner wall of the second sleeve 82 is fixedly connected with a second protrusion 821, and the second protrusion 821 matches the second groove 811. The second shaft rod 81 is slidably connected with the second sleeve 82. The second sleeve 82 is rotatably connected with the outer top surface of the mounting cover 4.

[0053] Since the second shaft rod 81 is clamped with the second groove 811 and the second protrusion 821 , the second sleeve 82 can not only enable the second shaft rod 81 to move in the vertical direction to ensure the normal movement of the moving frame, but also drive the second shaft rod 81 to rotate.

[0054] Reference Figure 3 and Figure 5 The top surface of the outer side of the mounting cover 4 is connected with a driving assembly 9, and the driving assembly 9 includes a cylinder 91, a rack 92, a first gear 93, a second gear 94, a first torsion spring 95, and a second torsion spring 96. The cylinder 91 is fixedly connected to the top of the mounting cover 4. The rack 92 is fixedly connected to the driving shaft of the cylinder 91 through a mounting plate. The driving direction of the rack 92 driven by the cylinder 91 is parallel to the length direction of the rack 92. The first gear 93 is sleeved on the first sleeve 72, and the second gear 94 is sleeved on the second sleeve 82. The rack 92 is meshed with the first gear 93 or the second gear 94.

[0055] The rack 92 moves linearly under the drive of the cylinder 91, and meshes with the first gear 93 or the second gear 94 during the movement. The first gear 93 rotates to drive the first sleeve 72 to rotate, and the second gear 94 rotates to drive the second sleeve 82 to rotate.

[0056] Reference Figure 3 and Figure 5 The first torsion spring 95 is sleeved on the first sleeve 72 and is disposed between the first gear 93 and the mounting cover 4. The first end of the first torsion spring 95 is fixedly connected to the mounting cover 4, and the second end is fixedly connected to the first sleeve 72. The second torsion spring 96 is sleeved on the second sleeve 82 and is disposed between the second gear 94 and the mounting cover 4. The first end of the second torsion spring 96 is fixedly connected to the mounting cover 4, and the second end is fixedly connected to the second sleeve 82.

[0057] When the rack 92 is separated from the first gear 93, the first torsion spring 95 prevents the first sleeve 72 from rotating automatically, thereby keeping the first gear 93 in a constant position, so that the rack 92 can mesh with the first gear 93 again. When the rack 92 is separated from the second gear 94, the second torsion spring 96 prevents the second sleeve 82 from rotating automatically, thereby keeping the second gear 94 in a constant position, so that the rack 92 can mesh with the second gear 94 again. The reciprocating motion of the rack 92 realizes the staggered motion of the first limiting piece 7 and the second limiting piece 8.

[0058] The principle of use of the present application is as follows: when in use, place the paper on the bottom plate 1, and leave one corner of the paper hanging in the air. Then, the paper is pressed by the pressing component 3 to reduce the movement of the paper during the counting process. Next, the paper counting device 5 is started, and the paper counting component 52 is first placed at the bottom of the paper, and the moving component 51 drives the paper counting component 52 to move upward, and the paper counting roller 523 pushes the paper away one by one during the rotation process. Every time the paper counting roller 523 pushes away a piece of paper, the counter 6 counts once.

[0059] During the paper counting process, the control module controls the start and stop of the first motor 511 and the second motor 521 and the speed according to the preset program. This enables the paper counting roller 523 to push the paper at a suitable speed and ensure that only one paper is pushed at a time. At the same time, the control module also receives the counting signal of the counter 6 in real time and displays the counting result on the display 61. In this way, the user can intuitively understand the current number of papers, so as to more conveniently perform subsequent operations.

[0060] And in the process of counting paper, every time the paper counting roller 523 pushes away a piece of paper, the driving component 9 will drive the first limiting piece 7 and the second limiting piece 8 to perform staggered movement. Specifically, when the paper counting roller 523 pushes away a piece of paper, the cylinder 91 will drive the rack 92 to move, thereby driving the first gear 93 or the second gear 94 to rotate. This makes the first limiting piece 7 or the second limiting piece 8 rotate to the top of the paper that has been counted, and limit it. When counting paper next time, another limiting piece will rotate to the top of the paper that has been counted, and staggered limiting will be achieved. In this way, it can effectively reduce the situation where the paper that has been counted is repeatedly counted or moved in the subsequent paper counting process, thereby improving the accuracy of counting.

[0061] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
