[0023] See attached Figure 5 As shown, in this embodiment, the swing drive unit 7 includes a transmission telescopic rod 71 for rotating in coordination with the swing bracket 61 and a swing drive motor 72 for driving the swing bracket 61 to swing, the two ends of the transmission telescopic rod 71 are respectively rotatably connected to the end of the swing bracket 61 and the frame 1, and the other end of the swing bracket 61 is rotatably connected to the frame 1, wherein one end of the swing bracket 61 is rotatably connected to the transmission telescopic rod 71 as a rotation point, and the other end of the swing bracket 61 is rotatably connected to the frame 1 as a fixed rotation center, and the swing drive motor 72 drives the swing bracket 61 to swing around the above-mentioned rotation center through the transmission telescopic rod 71. In addition, in this embodiment, the mechanism for rotating in coordination with the swing bracket 61 adopts the transmission telescopic rod 71, but is not limited to this form and can be replaced by a related connecting rotation mechanism, which is not limited here.

[0024] Furthermore, through the combined action of the above-mentioned translation drive unit 6 and the swing drive unit 7, the shift fork 5 is driven to move back and forth relative to the sheet counting wheel 3 according to a preset elliptical trajectory, so that the shift fork 5 can be movably inserted into the gap position between any two adjacent sheet counting slots 31 and lift the paper 8 pre-fed into the front sheet counting slot 31, so that a stacking gap is formed between the front paper 8 and the sheet counting wheel 3 for the paper 8 pre-fed into the rear sheet counting slot 31 to be inserted. With this reciprocating action, a plurality of sheets of paper 8 are stacked and fed into the paper output channel 4 from bottom to top. By setting the shift fork 5 to be movably inserted into the gap position between any two adjacent sheet counting slots 31, the movement of the shift fork 5 is avoided from interfering with the normal rotation of the sheet counting wheel 3, which is convenient for reducing maintenance costs and ensuring operating efficiency.

[0025] In this embodiment, a frame 1 is further included for connecting to the sheet counting wheel 3, the paper feeding channel 2 and the paper discharging channel 4, wherein the frame 1 is rotationally connected to the sheet counting wheel 3, and the frame 1 is fixedly connected to the paper feeding channel 2 and the paper discharging channel 4 respectively.

Corresponding mounting holes are formed on the frame 1. The above-mentioned drive motors are connected to the corresponding drive units inside the frame 1 through the corresponding mounting holes. This makes it easier to repair and replace the motors without disassembling the internal structure, thereby reducing maintenance costs.

[0027] See attached Figure 4 As shown, further, a feed drive unit 21 is provided on the paper feeding channel 2, and the feed drive unit 21 includes an inclined feed bracket 211, a first-level driving wheel 212, a first-level driven wheel 213, at least one first-level transmission belt 214 wound around the first-level driving wheel 212 and the first-level driven wheel 213, and a feed drive motor 215 for driving the first-level driving wheel 212 to rotate along the feeding direction, wherein the angle between the conveying direction of the feed bracket 211 and the horizontal direction is an acute angle, and by setting the feed bracket 211 to an inclined and raised state, the output paper 8 through the first-level transmission belt 214 can be fed one by one into the counting slot 31 on the counting wheel 3, and by relatively limiting the angle between the conveying direction of the feed bracket 211 and the horizontal direction, it is ensured that the paper 8 can be smoothly transported on the first-level transmission belt 214.

[0028] See attached Figure 4As shown, further, the paper discharge channel 4 is further provided with a baffle plate 42 for disengaging the paper 8 from the sheet counting slot 31 and at least one, preferably two, guide slides 44 for cooperating with the push palm 46 to push the stacked paper 8 away, wherein the baffle plate 42 is formed with at least one, preferably six, avoidance grooves 43 that penetrate and extend in the vertical direction, and the guide slides 44 are formed with guide grooves 45 for the push palm 46 to move; specifically, the push palm 46 pushes the rated number of stacked paper 8 away from the paper discharge channel 4 along the guide slides 44, and the guide slides 44 prevent the horizontally stacked paper 8 from being deflected during the movement; in addition, each avoidance groove 43 is used to avoid the sheet counting wheel 3, which is different from the traditional paper 8 counting device. In this embodiment, by providing a The baffle plate 42 blocks the sheet counting slot 31 with the paper 8 when the sheet counting wheel 3 rotates to the upstream position, so that the sheet counting slot 31 continues to rotate with the sheet counting wheel 3. Under the stopping action of the baffle plate 42, the paper 8 is separated from the sheet counting slot 31 and is placed in a horizontal state. Secondly, the paper 8 pre-fed into the front sheet counting slot 31 is lifted up by the shift fork 5, so that the paper 8 in the rear sheet counting slot 31 is inserted into the paper stacking gap, so that the paper 8 is stacked horizontally from bottom to top. Furthermore, by forming an avoidance groove 43 on the baffle plate 42, the baffle plate 42 cooperates with the sheet counting wheel 3. When the paper 8 is separated from the sheet counting slot 31, the rotating sheet counting wheel 3 is avoided, thereby not interfering with the normal operation of the sheet counting wheel 3 and avoiding affecting production.

[0029] In this embodiment, the paper discharge channel 4 is provided with a pushing palm 46 and a discharge driving unit 41 for pushing the rated number of stacked paper materials 8 away from the paper discharge channel 4. The discharge driving unit 41 includes a three-stage driving wheel 411, a three-stage driven wheel 412, a three-stage transmission chain 413 passed through the three-stage driving wheel 411 and the three-stage driven wheel 412, a connecting rod 415 for connecting the pushing palm 46 and the transmission chain, and a discharge driving motor 414 for driving the three-stage driving wheel 411 to rotate along the discharge direction. The two ends of the connecting rod 415 are slidably connected to the three-stage transmission chain 413, and the pushing palm 46 is embedded in the connecting rod 415. When the horizontally stacked paper materials 8 reach the rated number of sheets, the pushing palm 46 pushes the rated number of horizontally stacked paper materials 8 away from the paper discharge channel 4. Through the driving action of the discharge driving motor 414, the pushing palm 46 is reciprocatingly translated in the front and rear directions relative to the guide slide 44.

[0030] For the convenience of explanation, the following further explains the specific working process of the paper sheet counting mechanism 8.

[0031] During operation, first, the feed drive unit 21 conveys the paper 8 along the conveying direction of the primary transmission belt 214 to the upstream position of the counting wheel 3, and adopts a one-by-one loading method to feed the paper 8 on the output end of the primary transmission belt 214 into the counting slot 31 of the counting wheel 3, and transports it as the counting wheel 3 rotates; secondly, when the counting slot 31 with the paper 8 clamped therein rotates to the downstream position of the counting wheel 3, the baffle plate 42 on the paper feeding channel 2 stops and contacts the paper 8 on the counting slot 31 at this position and continues to rotate with the counting wheel 3, so that the paper 8 is detached from the counting slot 31.

[0032] In addition, when the front paper 8 is separated from the counting slot 31 and the paper 8 in the rear counting slot 31 gradually approaches the position of the baffle plate 42, the fork 5 driven by the combination of the translation drive unit 6 and the swing drive unit 7 is inserted into the gap position between the two adjacent counting slots 31 with the paper 8 clamped, and the paper 8 pre-fed into the front counting slot 31 is lifted, so that a stacking gap is formed between the front paper 8 and the counting wheel 3 for the paper 8 pre-fed into the rear counting slot 31 to be inserted, so that the paper 8 in the rear counting slot 31 is inserted into the stacking gap. Secondly, the fork 5 moves away from the above-mentioned gap position, and with this reciprocating action, several sheets of paper 8 are stacked and fed into the paper output channel 4 from bottom to top.

[0033] When the paper materials 8 are stacked from bottom to top into the guide slide 44 of the paper discharge channel 4, the three-stage transmission chain 413 in the discharge drive unit 41 drives the push palm 46 to feed along a preset direction, wherein the push palm 46 pushes the rated number of stacked paper materials 8 along the guide slide 44 to the next process, thereby completing the work of the paper counting mechanism.

Any person skilled in the art who, without departing from the scope of the present invention, utilizes the above-disclosed technical content to make further possible variations, modifications, or alterations to the present invention's technical solution shall constitute equivalent embodiments of the present invention.
