It should be understood that the terms "first", "second", etc. are used in the present utility model to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0030] like Figure 1 , Figure 2 As shown, the preferred embodiment of the paper sheet unloading rack of the utility model comprises:

[0031] A frame 1, wherein the frame 1 has a plurality of mounting holes 11 arranged horizontally and spaced apart on its circumference;

[0032] A plurality of adjustment bars 2 are arranged on the frame 1 in a divergent shape, each of the adjustment bars 2 has a mounting groove 21, and each of the mounting grooves 21 is connected to at least one mounting hole 11; one end of each adjustment bar 2 close to the divergent center is connected to a limiting rod 3 extending vertically upward, and each limiting rod 3 forms a positioning groove for positioning a paper pile 100 formed by stacking paper sheets;

[0033] A plurality of first fasteners 4 are provided, each of which is respectively inserted into a mounting hole 11 and a mounting groove 21 that are interconnected.

[0034] Specifically, each limiting rod 3 is arranged at intervals around the circumference of the paper pile 100, thereby surrounding the positioning groove. Therefore, by changing the position of each limiting rod 3, the shape of the positioning groove can be changed. In this embodiment, the frame 1 is a rectangular frame, and the front side plate of the rectangular frame is provided with two rows of mounting holes 11 arranged at intervals front and back, and the rear side plate of the rectangular frame is provided with two rows of mounting holes 11 arranged at intervals front and back. The mounting groove 21 is a long groove, and the mounting groove 21 passes through the adjustment strip 2 from top to bottom. Two first fasteners 4 are installed in the same mounting groove 21, and the two first fasteners 4 are respectively installed in the two mounting holes 11. After loosening the first fastener 4, the adjustment strip 2 can be moved along the length direction of the adjustment strip 2. After removing the first fastener 4, the installation position and installation direction of the adjustment strip 2 can be changed. Therefore, the position of the limiting rod 3 can be flexibly adjusted, and the size and shape of each positioning groove can be changed by changing the position of each limiting rod 3, so that the size and shape of the positioning groove can be suitable for paper sheets of various specifications. Therefore, the unloading rack of the utility model can be suitable for paper sheets of various specifications, and there is no need to customize the unloading rack for newly developed paper cups, thereby reducing the development cost of paper cups.

[0035] There are many ways to connect the limit rod 3 to the adjustment bar 2, such as welding the limit rod 3 to the end of the adjustment bar 2. In this embodiment, each adjustment bar 2 has a dividing groove 22 at one end close to the divergent center, and each dividing groove 22 divides the end of each adjustment bar 2 close to the divergent center into a first elastic arm 23 and a second elastic arm 24 that are relatively spaced apart in the horizontal direction.

[0036] The first elastic arm 23 and the second elastic arm 24 located on both sides of the same dividing groove 22 are respectively provided with a first clamping groove 231 and a second clamping groove 241, and the first clamping groove 231 and the second clamping groove 241 are arranged opposite to each other, and each limit rod 3 is respectively clamped in the corresponding first clamping groove 231 and the second clamping groove 241. The limit rod 3 is clamped in the adjustment bar 2, so that the limit rod 3 can be replaced easily and adjusted up and down easily.

[0037] Furthermore, each dividing groove 22 extends in the length direction of each adjustment strip 2, each first card groove 231 is arranged at the suspended end of each first elastic arm 23, and each second card groove 241 is arranged at the suspended end of each second elastic arm 24; each adjustment strip 2 is provided with an expansion groove 25 extending in the width direction of the adjustment strip 2 at the fixed end of each first elastic arm 23 and the fixed end of each second elastic arm 24, and the expansion groove 25 is connected with the dividing groove 22, and the expansion groove 25 can increase the elasticity below the elastic arm and the second elastic arm 24.

[0038] Furthermore, each first elastic arm 23 is provided with a second fastener 5 at a position close to the first clamping slot 231, and the other end of each second fastener 5 is respectively connected to each second elastic arm 24. Specifically, tightening the second fastener 5 can pull the first clamping slot 231 and the second clamping slot 241 closer to each other, so that the first clamping slot 231 and the second clamping slot 241 clamp the limit rod 3, and loosening the second fastener 5, the first clamping slot 231 and the second clamping slot 241 are restored to a position farther away under the action of elastic force, and the limit rod 3 can be adjusted up and down at this time.

[0039] In order to facilitate placing the paper pile 100 into the positioning groove, in this embodiment, the upper end of each limiting rod 3 is provided with a guide section 31 inclined toward the outside of the divergent center.

[0040] An embodiment of a paper sheet paging device, such as Figure 3 As shown, including the above-mentioned paper unloading rack, the lower end of each limit rod 3 is provided with a stop protrusion 32, and the lower end edge of the paper pile 100 abuts against the upper end of each stop protrusion 32;

[0041] The paper sheet paging device further includes a paper suction member 6 and a driving mechanism 7 for driving the paper suction member 6 to move up and down. The paper suction member 6 is arranged below the paper pile 100. The driving mechanism 7 drives the paper suction member 6 to move up so that the paper suction member 6 absorbs the middle of the paper sheet at the bottom of the paper pile 100. The driving mechanism 7 drives the paper suction member 6 to pull the middle of the paper sheet downward so that the middle of the paper sheet arches downward and the edge of the paper sheet shrinks toward the middle of the limiting groove so that the edge of the paper sheet crosses each stop protrusion 32. Specifically, after the paper pile 100 is placed in the positioning groove, the paper pile 100 falls onto each stop protrusion 32 under the action of its own gravity. The distance that the stop protrusion 32 protrudes from the outside of the limiting rod 3 is greater than or equal to 1 mm and less than or equal to 3 mm. In other embodiments of the utility model, the stop protrusion 32 may not be provided, and the position of each limiting rod 3 is set outside the inner hole contour of the frame 1, and the lower end of the paper pile 100 abuts against the inner hole edge of the frame 1. The driving mechanism 7 drives the paper suction member 6 to rise, and the paper suction member 6 sucks the paper sheet at the bottom of the paper pile 100. Then the driving mechanism 7 drives the paper suction member 6 to move downward. Since the paper sheet itself has elasticity, when the paper suction member 6 pulls the middle part of the paper sheet downward, the middle part of the paper sheet arches downward, and at the same time, the peripheral side of the paper sheet shrinks toward the center of the paper sheet. When the outer contour of the paper sheet shrinks to the outside of the stopping protrusions 32, the paper sheet crosses over the stopping protrusions 32 downward and follows the paper suction member 6 to descend, thereby paging the stacked paper sheets in sequence.

[0042] There are many ways to implement the driving mechanism 7 . In this embodiment, the driving mechanism 7 includes a crank slider mechanism 71 and a driving motor 72 for driving the crank of the crank slider mechanism 71 to rotate. The paper suction member 6 is connected to the slider of the crank slider mechanism 71 .

[0043] Specifically, the slider crank mechanism 71 includes a mounting frame 711, a wheel body 712, a shaft body 713, a connecting rod 714 and a guide rod 715. The mounting frame 711 is arranged below the limiting groove, the driving motor 72 is fixed to the lower part of the mounting frame 711, the wheel body 712 is connected to the output shaft of the driving motor 72, the shaft body 713 is fixed at the eccentric position of the wheel body 712, one end of the connecting rod 714 is rotatably connected to the shaft body 713, and the other end of the connecting rod 714 is rotatably connected to the lower end of the guide rod 715, and the upper end of the guide rod 715 slides through the mounting frame 711 and is connected to the paper suction member 6. In other embodiments of the utility model, the driving mechanism 7 can adopt a pneumatic cylinder.

[0044] In order to facilitate the adjustment of the stroke of the paper suction member 6, the connecting rod 714 in this embodiment is a telescopic rod. In this embodiment, the paper suction member 6 is a suction nozzle, and the suction nozzle is connected to a suction pipe. The suction pipe can suck the paper sheet by sucking air, and the suction pipe stops sucking air, and the suction nozzle releases the suction of the paper sheet, so that the paper sheet can be separated from the suction nozzle.

[0045] An embodiment of a paper sheet feeding system, such as Figure 4 As shown, including the above-mentioned paging device, the feeding system also includes a conveyor belt 8, the conveyor belt 8 has at least two belt bodies 81 arranged horizontally at intervals, the paper suction member 6 is arranged at the interval between two adjacent belt bodies 81, and the driving mechanism 7 drives the paper suction member 6 to descend to below the upper end surface of the belt body 81, so that the paper sheet falls to the upper end surface of the belt body 81. Specifically, the suction pipe draws air so that the paper suction member 6 sucks the paper sheet and moves it downward until the lower end of the paper sheet abuts against the upper end of the belt body 81, and then the suction pipe stops sucking air, and the driving mechanism 7 drives the paper suction member 6 to continue to move downward, and the paper sheet is separated from the paper suction member 6 and remains on the belt body 81. The belt body 81 moves to convey the paper sheet to the paper folding station, and then the driving mechanism 7 drives the paper suction member 6 to extend upward from the belt body 81, and sucks another paper sheet again, and so on. The cycle is repeated, so that each paper sheet of the paper pile 100 in the positioning groove is placed on the belt body 81 in sequence.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
