In the description of the embodiments of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0031] In one embodiment of the present invention, referring to Figure 1 to Figure 8, a paper counting device structure, including at least one group of reciprocating motion mechanism 10, an adsorption plate 20 and a driving mechanism 30 connected to the reciprocating motion mechanism, a stopper 40 and a negative pressure control device 50. The reciprocating motion mechanism 10 includes a mounting plate 100, a crank connecting rod mechanism 110 and a connecting member 120. The crank connecting rod mechanism 110 is rotatably connected to one side of the mounting plate 100 and connected to the driving mechanism 30. The driving mechanism 30 drives one end of the crank connecting rod mechanism 110 to cyclically move along the front, upper, rear and lower trajectory lines. The connecting member 120 is fixedly connected to the moving end of the crank connecting rod mechanism 110, and the adsorption plate 20 is fixedly connected to one end of the connecting member 120. The bottom of the adsorption plate 20 is provided with an adsorption hole 200, and the adsorption hole 200 is connected to the negative pressure control device 50, so that the mouth of the adsorption hole 200 forms a negative pressure; the stopper 40 is arranged on one side of the adsorption plate 20 in an up-down offset manner.

[0032] When counting the paper, the driving mechanism 30 drives the crank connecting rod mechanism 110, so that the adsorption plate moves forward, and a right angle position of the topmost paper is sucked up to the bottom of the adsorption plate 20 through the adsorption hole 200, and then the right angle position of the paper is driven to move upward so that the right angle of the paper is placed on the limiter 40, and after the adsorption plate 20 moves backward, it moves downward, so that the adsorption plate 20 moves to the bottom end of the limiter 40, and then moves forward, so that the second paper can be sucked up and moved upward. When the adsorption plate 20 moves upward, the paper overlapped on the limiter 40 can be lifted upward by the adsorption plate 20, so that the paper can avoid the movement track of the adsorption plate 20, and the cycle is continuous, so as to realize the counting of the paper. Since the paper is sucked up when counting the paper, under the action of the gravity of the paper, it is difficult to bring up the next paper when the upper paper is sucked up, so it can effectively avoid sucking multiple papers at a time, and ensure the accuracy of the paper counting. The crank-connecting rod mechanism 110 drives the adsorption plate 20 to move forward, upward, backward and downward in a circular motion, and the bottom surface of the adsorption plate 20 is always facing downward. Therefore, when the paper is sucked up, the adsorption force can be stabilized to effectively prevent the paper from falling, so that the adsorption plate can adsorb paper with a thickness of 200 grams to 400 grams; and the thick paper can be counted.

[0033] Furthermore, the driving mechanism 30 drives the crank connecting rod mechanism 110 to make the suction plate 20 cyclically move along the front, upper, rear and lower trajectory lines, and the bottom surface of the suction plate 20 is always facing downward. In this embodiment, when the right-angle position of the paper is sucked up, the problem of paper folding can be avoided, and when the suction plate 20 moves forward and backward, the distance between the suction plate 20 and the limiter 40 can be minimized, which can not only improve the counting efficiency, but also avoid the problem of right-angle transition deformation of the paper when the paper is sucked up.

[0034] Further, refer to Figure 1~Figure 4 The crank-connecting rod mechanism 110 includes a first eccentric wheel 111, a first connecting rod 112, a second connecting rod 113, a first rocking arm 114, a second eccentric wheel 115, a third connecting rod 116, a second rocking arm 117, a fourth connecting rod 118 and a connecting shaft 119. The first eccentric wheel 111 and the second eccentric wheel 115 are rotatably connected to one side of the mounting plate 100 in a front-to-back staggered manner, and an eccentric connecting portion is disposed on the outer side of the first eccentric wheel 111 and the second eccentric wheel 115. One end of the first connecting rod 112 is rotatably connected to the connecting portion of the first eccentric wheel 111, and the other end is pivotally connected to one end of the second connecting rod 113. One end of the first rocking arm 114 is pivotally connected to the mounting plate 100, and the other end is pivotally connected to the first connecting rod 112. One end of the third connecting rod 116 is rotatably connected to the connecting portion of the second eccentric wheel 115, and the other end is pivotally connected to one end of the fourth connecting rod 118. The connecting shaft 119 is fixedly passed through one end of the second connecting rod 113 away from the first connecting rod 112, and is rotatably connected to the other end of the fourth connecting rod 118. The connecting member 120 is fixedly connected to the connecting shaft 119. One end of the second rocking arm 117 is rotatably connected to the mounting plate 100, and the other end is rotatably connected to the third connecting rod 116. The driving mechanism 30 is connected to the first eccentric wheel 111 and / or the second eccentric wheel 115. In this embodiment, the first rocking arm 114 supports and connects the first connecting rod 112, and the second rocking arm 117 supports and connects the third connecting rod; the second connecting rod 113 and the fourth connecting rod 118 are connected as a whole by the connecting shaft 119; therefore, each connecting rod can be linked, and the connecting shaft 119 can reciprocate along a fixed track. Specifically, the first eccentric wheel 111 and the second eccentric wheel 115 are driven to rotate by the driving mechanism 30, the eccentric connecting part of the first eccentric wheel 111 pushes the first connecting rod 112, and the eccentric connecting part of the second eccentric wheel 115 pushes the fourth connecting rod 118, thereby pushing the second connecting rod 113, the third connecting rod 116, the first rocker arm 114 and the second rocker arm 117 to work in conjunction, thereby pushing the connecting shaft 119 to circulate along a fixed trajectory; and during the operation, when the connecting shaft 119 moves downward from the highest point, the connecting shaft 119 will drive the adsorption plate 20 to swing slightly at a certain angle, so as to better avoid the limit member 40.

[0035] Further, see Figure 4 and Figure 5, an embodiment of the dimensions of the first connecting rod 112, the second connecting rod 113, the first rocker arm 114, the third connecting rod 116, the second rocker arm 117 and the fourth connecting rod 118, specifically, the distance between A and G is 14mm; the distance between B is 55mm; the distance between C is 45mm; the distance between D is 40mm; the distance between E is 80mm; the distance between F is 50mm; the distance between H is 30mm; the distance between K is 52mm, and the distance between O is 50mm. The above dimensions are only an embodiment. Proportional scaling on this dimension can enable the connecting shaft 119 to realize cyclic motion along the front, upper, rear and lower trajectory lines.

[0036] Furthermore, a through hole is provided in the connecting shaft 119, the outer end of which is connected to the pipeline of the negative pressure control device 50, and the other end is connected to the adsorption hole 200 of the adsorption plate 20. In this embodiment, the negative pressure control device 50 is connected to the connecting shaft 119 and connected to the end of the connecting shaft 119, so that when the adsorption plate 20 moves along the trajectory line, the air pipe connected to the adsorption hole 200 is prevented from interfering with the reciprocating motion of the adsorption plate 20.

[0037] Further, refer to Figure 1~Figure 3 , the number of the reciprocating motion mechanisms 10 is two groups, and they are arranged opposite to each other. The limiter 40 and the adsorption plate 20 are respectively connected to the moving end of the reciprocating motion mechanism 10. The limiter 40 has the same structure as the adsorption plate 20, and is connected to the negative pressure control device 50. The driving mechanism 30 drives the adsorption plate 20 and the limiter 40 to reciprocate alternately. In this embodiment, the limiters 40 and the adsorption plates 20 on the two groups of reciprocating motion mechanisms 10 are driven by the driving mechanism 30 to reciprocate alternately, so that the adsorption plates 20 and the limiters 40 reciprocate to adsorb the paper, thereby improving the efficiency of paper counting. Furthermore, when the adsorption plate 20 sucks up a right angle of the paper, the stopper 40 is driven by the corresponding reciprocating mechanism 10 to descend and move to the bottom of the adsorption plate 20, and then can receive the paper adsorbed by the adsorption plate 20. After the adsorption plate 20 releases the paper and gradually moves back and down, the stopper 40 sucks up another paper. After sucking up, the adsorption plate 20 moves to the bottom of the stopper 40, and this cycle is repeated to achieve continuous counting. Furthermore, when the adsorption plate 20 and the stopper 40 suck up the paper, it can avoid the stopper 40 or the adsorption plate 20 blocking the paper, and avoid the right angle of the paper being bent and deformed when the paper is sucked up, especially the paper with a gram weight of more than 200. Therefore, the paper counting device structure of this embodiment can be used for counting and layering thick paper, and will not cause paper deformation, so as to achieve a good protection effect on the starting point of the paper.

[0038] Further, refer to Figure 6The first transmission shaft 101 and the second transmission shaft 102 are rotatably connected between the mounting plates 100 in the two sets of the reciprocating motion mechanisms 10. The two first eccentric wheels 111 are relatively connected to the two ends of the first transmission shaft 101, and the two second eccentric wheels 115 are relatively connected to the two ends of the second transmission shaft 102. In this embodiment, the crank-connecting rod mechanism 110 of one set can be driven by the driving mechanism 30 to drive the crank-connecting rod mechanism 110 of the other set, thereby realizing the reciprocating operation of the two sets of crank-connecting rod mechanisms 110 in linkage.

[0039] Reference Figure 2 and Figure 4 The driving mechanism 30 includes a motor 300, a driving wheel 301, two driven wheels 302, a transmission belt 303 and a tensioning roller 304. The motor 300 is connected to a mounting plate 100, the driving wheel 301 is connected to the main shaft of the motor 300, and the two driven wheels 302 are respectively connected to the first transmission shaft 101 and the second transmission shaft 102. The transmission belt 303 connects the driving wheel 31 and the two driven wheels 302, and the tensioning roller 304 is arranged on the mounting plate 100 for tightening the transmission belt 303. In this embodiment, the driving wheel 301 is driven by the motor 300, and the driven wheels 302 are driven by the transmission belt 303, thereby driving the first eccentric wheel 111 and the second eccentric wheel 115 of the two crank-connecting rod mechanisms 110 to rotate simultaneously.

[0040] Furthermore, the negative pressure control device 50 includes a turntable 500, a fixed plate 501, a rubber disc 502 and a ventilation plate 503. The turntable 500 is rotatably arranged on the outer side of the mounting plate 100 and is connected to the driving mechanism 30; a connecting portion extends from the outer side of the turntable 500, and the rubber disc 502 is connected to the connecting portion. The fixed plate 501 is fixed to the outer side of the mounting plate 100 and extends to the outer side of the turntable 500. The mounting plate 100 is provided with a avoidance hole for avoiding the air-avoiding rubber disc 502, and the rubber disc 502 passes through the avoidance hole. The ventilation plate 503 is fixedly connected to the outer side of the mounting plate 100 and is sealed with the rubber disc 502. The surface where the rubber disc 502 and the ventilation plate 503 are in contact is provided with an air cavity 505. The ventilation plate 503 is provided with three air holes 506, one of which is connected to the negative pressure system pipeline and is always connected to the air cavity, and the other two air holes are alternately connected to the air cavity 505. The adsorption plate 20 and the limiter 40 are connected to the corresponding air holes. In this embodiment, the turntable 500 is driven to rotate by the driving mechanism 30, so that the adsorption holes at the bottom of the adsorption plate 20 and the limiter 40 alternately generate negative pressure. When the adsorption holes 200 at the bottom of the adsorption plate 20 adsorb paper, the adsorption holes at the bottom of the limiter 40 lose negative pressure, so the cycle can achieve continuous paper adsorption and release.

[0041] Further, refer to Figure 2 , Figure 3 and Figure 7 A separation belt conveying mechanism 60 is further provided inside the mounting plate 100 of the reciprocating mechanism 10, for conveying the separation belt to the bottom of the counted paper pile. In this embodiment, after a certain number of paper is counted, the separation belt conveying mechanism 60 conveys a separation belt to the middle of the counted and uncounted paper piles, so as to achieve the effect of isolating the separated paper piles into layers. Therefore, in the process of counting the paper piles into layers, multiple layers of paper piles can be counted at one time, thereby improving the counting and layering efficiency.

[0042] Further, refer to Figure 7 The isolation belt conveying mechanism 60 includes a conveying pipe 600, a rotating shaft 601, a connecting shaft 602, a swing arm 603, a telescopic electromagnet 604, a mounting shaft 605, a driving gear 606, a driven gear 607, a conveying roller 6000, a pressure wheel 608 and a cutter mechanism 609. The conveying pipe 600, the connecting shaft 602 and the telescopic electromagnet 604 are all arranged on the inner side of the mounting plate 100, the rotating shaft 601 is rotatably connected to the inner side of the mounting plate 100, one end of the swing arm 603 is rotatably connected to the connecting shaft 602, and the other end is rotatably connected to the telescopic end of the telescopic electromagnet 604, so as to pull the swing arm 603 to swing up and down around the connecting shaft 602. The installation shaft 605 is rotatably connected to the swing arm 603, the driven gear 607 and the pressure wheel 608 are arranged on the installation shaft 605, the driving gear 606 and the conveying roller 6000 are arranged on the rotating shaft 601, the driving gear 606 is meshed with the driven gear 607, and the conveying pipeline 600 is provided with a clearance groove for avoiding the pressure wheel 608 and the conveying roller 6000 from being attached to the conveying isolation belt. The rotating shaft 601 is connected to the driving mechanism 30. The cutter mechanism 609 is arranged at one end of the installation plate 100 close to the adsorption plate 20, and is used to cut off the isolation belt output by the conveying pipeline 600. Specifically, the rotating shaft 601 is connected to the turntable 500 with a belt. The isolation paper tape passes through the conveying pipe 600. When the isolation paper tape needs to be inserted into the paper pile, the telescopic electromagnet 604 pulls the swing arm 603 to swing downward, so that the pressure wheel 608 presses the paper tape against the conveying roller 6000. The driving mechanism 30 drives the pressure wheel 608 and the conveying roller 6000 to rotate, thereby outputting the paper tape, and then the paper tape is cut by the cutter mechanism 609.
