For easy operation, such as figure 1 As shown, a handle 33 is fixed on the rotating shaft 32. To further facilitate operation, a first spring (not shown in the figure) is provided between the hook 31 and the paper pressing assembly 1, and the lower side wall of the groove of the hook 31 is chamfered to make the The hook 31 is clamped with the locking column 34 under the action of the first spring.
[0041] The first driving device can be implemented using existing technologies such as motors. Such as figure 1 with 2 As shown, the first driving device in this embodiment is a rotating electromagnet 29. The rotating electromagnet 29 is fixed on the first lower side plate 23. In this embodiment, the rotating electromagnet 29 is realized by a rotating electromagnet of model KSA30H11A. To facilitate the debugging of this ballot sorting module, such as figure 1 with 2 As shown, the rotating electromagnet 29 is connected with an angle adjustment device that adjusts its installation angle to change the start position and end position of the sorting element 22, so that when the sorting element 22 is at the start position, the first channel 7 and The second channel 5 is directly connected to each other; when the sorting element 22 is at the end position, the first channel 7 and the third channel 6 are directly connected to each other. Specifically, in this embodiment, as figure 1 with 2 As shown, the rotating electromagnet 29 is rotationally connected with the first lower side plate 23, and the rotation axis of the rotating electromagnet 29 coincides with the rotation axis of the sorting element 22. Such as Image 6 As shown, the angle adjusting device includes an adjusting rod 28; the middle of the adjusting rod 28 is rotatably connected to the first lower side plate 23, one end of the adjusting rod 28 is inserted into the slot of the rotating electromagnet 29, and the other of the adjusting rod 28 An arc-shaped elongated hole 281 is opened at one end, a screw (not shown in the figure) is arranged in the elongated hole 281, and a threaded hole for threaded engagement with the screw is opened on the corresponding first lower side plate 23. Therefore, by changing the position of the adjusting rod 28, the installation position of the rotary electromagnet 29 can be changed.
[0042] working principle:
[0043] According to the information of the ballot, such as gender information or valid and invalid information, the reader judges which sorting channel the ballot should pass through to the corresponding receiving tray, and sends the signal to the first driving device, which is based on the information sent by the reader The signal drives the sorting element 22 to rotate to the origin position or the end position. At the same time, the ballot enters the first channel 7 through the exit of the reader, and the pressure roller 12 and the paper feed roller 21 clamp the ballot, driven by the second driving device , The paper feed roller 21 rotates to transport the ballots away from the reader. If the sorting element 22 is located at the origin, that is image 3 In the position shown, the ballot will be sent out from the second channel 5 and enter the paper receiving tray corresponding to the second channel 5 (not shown in the figure); if the sorting element 22 is at the end position, that is Figure 4 In the position shown, the ballot will be sent out from the third channel 6 into the paper receiving tray corresponding to the third channel 6 (not shown in the figure). Thereby, the automatic sorting of ballots is completed, human error is avoided, and the sorting efficiency is greatly improved.
[0044] When a card ballot appears or the ballot sorting module needs to be maintained, open the locking structure between the paper feeding assembly 2 and the paper pressing assembly 1, and rotate the paper pressing assembly 1 upward to take out the stuck ballot, or Maintain this ballot sorting module. The reader needs a certain reaction time to read the ballot, so the length of the first channel 7 must meet the reaction time of the reader. Usually, to sort an A4 paper ballot, the length of the entire ballot sorting module is about 630mm. If the ballot is larger, then a longer ballot sorting module needs to be made. Therefore, if the axis of rotation of the paper pressing assembly 1 relative to the paper feeding assembly 2 is perpendicular to the conveying direction of the ballots, the torque acting on the rotating parts between the paper pressing assembly 1 and the paper feeding assembly 2 will be larger, resulting in damage to the rotating parts The speed is increased, and at the same time, in order to ensure sufficient operating space when the paper pressing assembly 1 is opened, the opening angle of the paper pressing assembly 1 is larger, which increases the floor area, and at the same time easily causes the center of gravity of the ballot sorting module to be unstable and toppling. Therefore, in this embodiment, by making the relative rotation axis of the paper pressing assembly 1 and the paper feeding assembly 2 parallel to the conveying direction of the ballot, the torque acting on the rotating member between the paper pressing assembly 1 and the paper feeding assembly 2 is reduced, At the same time, it provides a larger opening and closing angle in a limited space for easy operation. What needs to be said is that the reader adopts existing technology. In this embodiment, the reading machine is realized by the intelligent ticket counting integrated machine disclosed by the applicant in the patent CN201710178946.0. It is understandable that you only need to take out the paper output bin of the smart ticket counting machine in CN201710178946.0, and then connect the entrance of the first channel of the scanning ballot sorting module to the exit of the smart ticket counting machine.
