[0038] The pick-up wheel assembly 300 has a pick-up wheel 310 that rotates in a set direction. In this embodiment, there are two pick-up wheels 310, each of which is located between two pickup wheels 110. This structure is reasonable in layout, reduces the space occupied by the medium separation device, and is conducive to product miniaturization. A channel for conveying a single medium is formed between the pick-up wheel 310 and the reversing wheel 210. The rotation of the pick-up wheel 310 is used to provide conveying power for each medium conveyed by the pickup wheel 110, so that the medium can be moved;
[0039] The follower wheel assembly 400 has a follower wheel 410 that floats and fits with the separation wheel 310.

[0044] Specifically, the frame member 500 includes a horizontally arranged support plate 510 and side plates 520 respectively fixed to two ends of the support plate 510 and vertically arranged relative to the support plate 510 .
[0045] Overview of the pick-up wheel assembly as an example
[0046] like Figure 3As shown, specifically, the pick-up wheel assembly 100 includes a pick-up shaft 120, and the pick-up wheel 110 rotates around the pick-up shaft 120. The pick-up wheel 110 includes a pick-up wheel body 111 and a friction portion 112 detachably embedded in the pick-up wheel body 111 for frictionally feeding each medium. A detachable connection method is adopted to facilitate timely replacement of the worn friction portion 112 without replacing the pick-up wheel body 111 as a whole, thereby saving costs. In this embodiment, a card slot 1111 is provided on the pick-up wheel body 111, which is adapted to the friction portion 112 and can fix and limit the friction portion 112. The friction portion 112 is disassembled and assembled from the card slot 1111 to achieve a detachable connection.
[0047] Furthermore, the outer peripheral surface of the friction part 112 is provided with a plurality of first notches 1121 arranged at intervals for increasing the friction between the friction part 112 and the medium. The friction between the friction part 112 and the medium is increased by forming a plurality of friction areas 1122 between two first notches 1121 and a plurality of first notches 1121 .
[0048] Overview of the counter-rotating wheel assembly as an example
[0049] like Figure 1 and Figure 2 As shown, specifically, the reversing wheel assembly 200 includes a reversing shaft 220 rotatably disposed on the frame member 500, the reversing wheel 210 is fixedly sleeved on the reversing shaft 220, the reversing wheel 210 is circumferentially provided with at least one second recess 211, and the reversing wheel 210 is provided with two abutment portions 212 located on both sides of the second recess 211 for contacting with the medium.
[0050] Overview of the take-off wheel assembly as an example
[0051] like Figure 4 As shown, specifically, the rubbing wheel assembly 300 includes a rubbing shaft 320 rotatably arranged on the frame member 100, the rubbing wheel 310 is fixedly sleeved on the rubbing shaft 320, and the rubbing wheel 310 is circumferentially provided with two third recesses 311 respectively corresponding to the two abutting portions 212, the two third recesses 311 are spaced apart, a middle rubbing wheel 312 corresponding to the second recess 211 is formed between the two third recesses 311, and two side rubbing wheels 313 are respectively formed on the outer sides of the two third recesses 311.
[0052] In this embodiment, there are two pick-up wheels 310 , and each pick-up wheel 310 is located between two pick-up wheels 110 , so as to quickly receive the medium frictionally transported by the pick-up wheels 110 .
[0053] like Figure 1 and Figure 2As shown, in this embodiment, the picking shaft 120 of the picking wheel assembly 100 is connected to the rubbing shaft 320 through a connecting piece 600, so that the picking shaft 120 of the picking wheel assembly 100 does not need to be connected to the frame member 500. With this structural design, the picking shaft 120 and the rubbing shaft 320 can achieve power transmission through a synchronous belt or gear meshing. A passive picking gear 121 is fixedly sleeved on the picking shaft 120, and a fixed sleeve is provided on the outer periphery of the rubbing shaft 320 to engage with the passive picking gear 121. The passive rubbing gear 321 arranged adjacent to the pick-up wheel 110 can simultaneously drive the passive pick-up gear 121 and the passive rubbing gear 321 to rotate in the same direction through a driving gear, thereby saving costs and facilitating large-scale production; wherein, one end of the connecting member 600 is rotatably connected to the rubbing shaft 320, so that the connecting member 600 can rotate around the rubbing shaft 320, and under the action of external elastic force, reliable contact between the pick-up wheel 110 and the medium is ensured and a certain pre-tightening force is maintained, thereby avoiding the phenomenon of pick-up failure or pick-up tilt of the pick-up wheel 110.
[0054] Specifically, the rubbing wheel 310 includes a rubbing body 314 and a rubbing portion 315 connected to the rubbing body 314, and the rubbing portion 315 is provided with a toothed structure 3151 for increasing the friction between the medium and the rubbing body 314. The toothed structure 3151 and the follower wheel 410 are staggered, which can effectively avoid the phenomenon of slipping of the medium during transportation.
[0055] The outer peripheral surface of the stripping body 314 is fixed with stripping body ribs 3141 for strengthening the fixation of the stripping part 315. The stripping part 315 is strengthened and fixed by the stripping body ribs 3141. At the same time, the stripping body ribs 3141 arranged on the outer periphery of the stripping body 314 can isolate the medium, effectively avoiding the phenomenon of stripping another medium into the channel when conveying the medium. Among them, the auxiliary feature is not limited to the stripping body ribs 3141 of the stripping wheel 310, adding new parts, or being composed of the ribs of the channel. The utility model adopts the first one, which is both economical and avoids the phenomenon of wrong separation of the medium.
[0056] Preferably, the rubbing part 315 is integrally formed with the rubbing body 314 or the rubbing part 315 is detachably embedded in the rubbing body 314, which is convenient for disassembly and assembly, and is convenient for timely replacement of the damaged rubbing part 315. The preferred assembly methods of the rubbing body 314 and the rubbing part 315 of the rubbing wheel 310 are casting and embedding. When casting, the rubbing body 314 serves as the core of the rubbing part 315 and is integrally formed. When embedding, the rubbing part 315 is separately formed and then mounted on the rubbing body 314. The two methods have their own advantages and can be flexibly selected according to the actual situation of the manufacturer to improve accuracy and efficiency and reduce defective products and production costs.
[0057] The separation body 314 of the separation wheel 310 is manufactured by mold injection molding, which greatly reduces material cost and processing cost while ensuring product accuracy.
[0058] like Figure 5 and Figure 6 As shown, in this example, the separation portion 315 is detachably embedded in the separation body 314, and the separation body 314 is axially provided with an embedding groove 3142. Both sides of the bottom of the embedding groove 3142 are respectively provided with groove holes 3143 for fixing the separation portion 315 to the separation body 314 and connecting and positioning. The position and curvature of the groove hole 3143 can achieve the goal that the extraction hole (sleeve) and the slider on the mold do not interfere with each other, the movement between the two is not front and back, and the mold manufacturing and production control are convenient, and the separation portion 315 can be reliably fixed in the radial direction of the separation body 314; it is convenient to process the separation body 314 and the separation portion 315, and the manufacturing cost is low.
[0059] A toothed structure is provided on one axial side of the side rubbing wheel 313 of the rubbing wheel 310, which ensures the dirt-resistance of the rubbing wheel 310 and extends the service life of the rubbing wheel 310; while no toothed structure is provided on the other axial side of the side rubbing wheel 313 of the rubbing wheel 310, which effectively avoids the jumping phenomenon of the follower wheel 410 that is in contact with the side rubbing wheel 313, ensures that the rubbing part 315 of the rubbing wheel 310 stably and reliably transports the medium, while reducing noise and reducing the shaking fatigue of related components.
[0060] Overview of follower wheel assembly as an example
[0061] like Figure 1 and Figure 2 As shown, further, the follower wheel assembly 400 includes an elastic assembly 420 for applying an elastic thrust to the follower wheel 410 so that the follower wheel 410 floats and fits with the rubbing wheel 310. In this embodiment, there are preferably two follower wheels 410, which float and fit with the rubbing wheels 313 on both sides respectively.
[0062] The elastic component 420 includes a horizontally arranged support member 421 for supporting the follower wheel 410 and a vertically arranged connecting rod 422 that passes through the frame member 500. The connecting rod 422 is sleeved with an elastic member 423 that is respectively in contact with the support plate 510 and the connecting member 421 of the frame member 500. The elastic member 423 is stretched or compressed to make the rubbing wheel 310 and the follower wheel 410 float and fit together. The manufacturing is simple and the cost is low.
[0063] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
