The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0046] Please refer to Figure 1 , this embodiment provides a cash recycling device. The cash recycling device includes a coin input device 100, and the coin input device 100 is used to receive banknotes put in by users.

[0047] Please continue to refer to Figure 1, Optionally, the cash recycling processing device further includes a banknote dispensing device 200, a reading device 300, and a plurality of cash boxes. Among them, the reading device 300 is used to collect information of banknotes, the banknote dispensing device 200 is used to output banknotes to users, and the cash boxes are used to store the banknotes input by the coin insertion device 100 or output banknotes to the banknote dispensing device 200. In this embodiment, the plurality of cash boxes include a counterfeit money box 400, a recycling box 500, a storage box 600, and a loading box 700. The counterfeit money box 400 is used to receive counterfeit money input by the coin insertion device 100 during deposit. The recycling box 500 is used to receive banknotes input by the coin insertion device 100 during deposit and output banknotes during withdrawal. The storage box 600 is used to receive large-denomination banknotes during deposit, abnormal banknotes identified by the reading device 300 during withdrawal and loading, and banknotes output by the recycling box 500 during cash clearing. The loading box 700 is used to load banknotes into the recycling box 500.

[0048] Please refer to Figure 2 and Figure 3 , The coin insertion device 100 includes a frame 10, a coin kicking roller 20, a coin separating roller 30, a coin blocking roller 40, and a roller 50. Among them, the coin kicking roller 20, the coin separating roller 30, the coin blocking roller 40, and the roller 50 are all arranged on the frame 10. Along the advancing direction of the banknote, the roller 50, the coin kicking roller 20, and the coin separating roller 30 are arranged in sequence, and the roller 50, the coin kicking roller 20, and the coin separating roller 30 are all used to drive the banknote to advance. The coin blocking roller 40 is opposite to the coin separating roller 30, and the coin blocking roller 40 and the coin separating roller 30 cooperate to prevent overlapping banknotes from entering between the coin separating roller 30 and the coin blocking roller 40. With such an arrangement, the banknotes put in by the user are conveyed to the coin separating roller 30 under the drive of the roller 50 and the coin kicking roller 20. The coin separating roller 30 cooperates with the coin blocking roller 40 to make the banknotes pass through between the coin separating roller 30 and the coin blocking roller 40 one by one and continue to be conveyed to the reading device 300. Specifically, in this embodiment, the frame 10 is provided with a receiving cavity 101. The roller 50 and the coin kicking roller 20 are both arranged on the bottom wall 102 of the receiving cavity 101. The coin kicking roller 20 includes a coin kicking wheel 201 and a coin kicking friction part 202 installed on the coin kicking wheel 201. The coin kicking friction part 202 protrudes from the outer circumference of the coin kicking wheel 201 and is used to drive the banknote in contact with it to move. Each time the coin kicking roller 20 rotates one circle, the coin kicking friction part 202 contacts the banknote once, and when the coin kicking friction part 202 contacts the banknote, it can drive the banknote to move to complete one coin kicking. The roller 50 can move the bottommost banknote to the coin kicking roller 20 before the coin kicking roller 20 kicks the coin, ensuring that when the stack of banknotes put into the coin insertion device 100 by the user is not neatly arranged, the coin kicking roller 20 can also first drive the bottommost banknote to move towards the coin separating roller 30, preventing multiple banknotes from entering between the coin separating roller 30 and the coin blocking roller 40 at the same time, and greatly reducing the requirements for the state of the banknotes placed by the user into the receiving cavity 101.

[0049] Please refer to Figure 4 and Figure 5, the roller 50 includes a wheel body and a friction portion 3. The wheel body includes a first wheel body 1 and a second wheel body 2 that are coaxial and interconnected. Along the axial direction of the wheel body, the friction portion 3 is inserted into both the first wheel body 1 and the second wheel body 2 at the same time, and the lengths of both the first wheel body 1 and the second wheel body 2 are less than the length of the friction portion 3, and the sum of the lengths of the first wheel body 1 and the second wheel body 2 is greater than or equal to the length of the friction portion 3. For the roller 50 provided in this embodiment, the longer wheel body is axially split into two shorter first wheel bodies 1 and second wheel bodies 2. When assembling the roller 50, the two ends of the friction portion 3 can be respectively inserted into the first wheel body 1 and the second wheel body 2 first, and then the first wheel body 1 and the second wheel body 2 are coaxially connected. Since the split first wheel body 1 and second wheel body 2 are both shorter, the installation strokes of the friction portion 3 relative to the first wheel body 1 and the second wheel body 2 are also shorter. Therefore, it is relatively easy to realize the connection between the friction portion 3 and the first wheel body 1 and the second wheel body 2, thereby improving the assembly efficiency of the roller 50.

[0050] Optionally, please refer to Figure 4 and Figure 5 , the structures of the first wheel body 1 and the second wheel body 2 are the same, and along the axial direction of the wheel body, the first wheel body 1 and the second wheel body 2 are symmetrically arranged with respect to the length center line of the friction portion 3. Such a setting makes it unnecessary to distinguish between the first wheel body 1 or the second wheel body 2 when installing the roller 50, improving the assembly efficiency of the roller 50, and the first wheel body 1 and the second wheel body 2 can share the same set of molds for processing, saving design and processing costs.

[0051] Optionally, the friction coefficient between the friction portion 3 and the thin sheet-like medium is higher than the friction coefficients between the first wheel body 1 and the second wheel body 2 and the thin sheet-like medium. Preferably, the material of the friction portion 3 can be made of rubber material. In this embodiment, when the roller 50 rotates, the friction portion 3 contacts the banknote and drives the banknote to move, which can ensure the reliability of the roller 50 to drive the banknote to move.

[0052] Optionally, please refer to Figures 4 to 6 , the friction portion 3 is provided with an arc-shaped driving surface 311, and the center line of the driving surface 311 coincides with the axis of the wheel body or the center line of the driving surface 311 is parallel to the axis of the wheel body and is spaced apart. Such a setting can ensure that the friction portion 3 has sufficient driving force on the banknote, thereby ensuring the stability of the friction portion 3 to drive the banknote to move. Preferably, the friction portion 3 includes a plurality of tooth-shaped protrusions 31, each tooth-shaped protrusion 31 extends along the axial direction of the wheel body, and the plurality of tooth-shaped protrusions 31 are arranged at intervals along the circumferential direction of the wheel body to form the driving surface 311. Such a setting further improves the driving force of the friction portion 3 on the thin sheet-like medium.

[0053] Optionally, please continue to refer to Figures 4 to 6, the first wheel body 1 includes a first installation groove 11, the second wheel body 2 includes a second installation groove 21, and the first end of the first installation groove 11 is communicated with the first end of the second installation groove 21; the first wheel body 1 further includes a first limiting portion 12 that seals the second end of the first installation groove 11 facing away from the second installation groove 21, and the second wheel body 2 further includes a second limiting portion 22 that seals the second end of the second installation groove 21 facing away from the first installation groove 11. The friction portion 3 includes an installation portion 32. The installation portion 32 is inserted into both the first installation groove 11 and the second installation groove 21 at the same time, and the first end of the installation portion 32 abuts against the first limiting portion 12, and the second end of the installation portion 32 abuts against the second limiting portion 22. With such a setting, when installing the friction portion 3, first insert the first end of the installation portion 32 into the first installation groove 11 from the first end of the first installation groove 11, then make the first end of the installation portion 32 abut against the first limiting portion 12, and then insert the second end of the installation portion 32 into the second installation groove 21 from the first end of the second installation groove 21, and then make the second end of the installation portion 32 abut against the second limiting portion 22, which can realize the assembly of the friction portion 3 with the first wheel body 1 and the second wheel body 2. The installation strokes of the installation portion 32 relative to the first installation groove 11 and the second installation groove 21 are both short, and it is easier to install the installation portion 32 in the first installation groove 11 and the second installation groove 21; and the first limiting portion 12 and the second limiting portion 22 jointly limit the position of the friction portion 3 relative to the first wheel body 1 and the second wheel body 2 along the axial direction of the wheel body, so that the position of the friction portion 3 relative to the first wheel body 1 and the second wheel body 2 is fixed along the axial direction of the wheel body.

[0054] As an alternative solution, since the friction portion 3 is made of rubber material and the friction portion 3 has elasticity, therefore, limiting portions can also be respectively provided in the first installation groove 11 and the second installation groove 21. The limiting portions are used for extrusion cooperation with the friction portion 3. The friction portion 3 elastically deforms under the extrusion of the limiting portions, and the purpose of restricting the relative positions of the friction portion 3 with the first installation groove 11 and the second installation groove 21 can also be achieved.

[0055] Optionally, please continue to refer to Figures 4 to 6, the first wheel body 1 further includes a first support portion 13. The friction portion 3 is sleeved on the first support portion 13. The first support portion 13 includes a first support surface 131 and two first inclined surfaces 132. The first support surface 131 abuts against the inner wall of the friction portion 3, and the first support surface 131 is used to support the friction portion 3. The first ends of the two first inclined surfaces 132 are respectively connected to the two ends of the first support surface 131. The second ends of the two first inclined surfaces 132 both extend in the direction close to the axis of the wheel body. A first avoidance space 133 is formed between each first inclined surface 132 and the inner wall of the friction portion 3. With such a setting, when the friction portion 3 is sleeved on the first support portion 13, the setting of the first avoidance space 133 can reduce the contact area between the inner wall of the friction portion 3 and the first support portion 13, improving the ease of installation of the friction portion 3. Moreover, when the friction portion 3 drives the thin sheet-like medium to move, the portion of the friction portion 3 that forms the first avoidance space 133 can undergo elastic deformation and generate a restoring force in the direction of movement of the thin sheet-like medium, further increasing the driving force of the friction portion 3 on the thin sheet-like medium.

[0056] Optionally, please refer to Figures 4 to 5 , the second wheel body 2 includes a second support portion 23. The friction portion 3 is sleeved on the second support portion 23. The second support portion 23 includes a second support surface 231 and two second inclined surfaces 232. The second support surface 231 abuts against the inner wall of the friction portion 3, and the second support surface 231 is used to support the friction portion 3. The first ends of the two second inclined surfaces 232 are respectively connected to the two ends of the second support surface 231. The second ends of the two second inclined surfaces 232 both extend in the direction close to the axis of the wheel body, and a second avoidance space is formed between each second inclined surface 232 and the inner wall of the friction portion 3. With such a setting, when the friction portion 3 is sleeved on the second support portion 23, the setting of the second avoidance space can reduce the contact area between the inner wall of the friction portion 3 and the second support portion 23, improving the ease of installation of the friction portion 3. Moreover, when the friction portion 3 drives the thin sheet-like medium to move, the portion of the friction portion 3 that forms the second avoidance space can undergo elastic deformation and generate a restoring force in the direction of movement of the thin sheet-like medium, further increasing the driving force of the friction portion 3 on the thin sheet-like medium.

[0057] Optionally, please refer to Figures 4 to 6, in the circumferential direction of the wheel body, the first installation groove 11 is located on one side of the first support portion 13; the second installation groove 21 is located on one side of the second support portion 23; the friction portion 3 includes a long groove 33 extending in the axial direction of the wheel body. In the circumferential direction of the wheel body, the installation portion 32 is located on one side of the long groove 33. The long groove 33 is sleeved with both the first support portion 13 and the second support portion 23 in the axial direction of the wheel body. The installation portion 32 is inserted and matched with both the first installation groove 11 and the second installation groove 21 in the axial direction of the wheel body. In this way, the relative position of the friction portion 3 and the wheel body in the radial direction of the wheel body can be restricted, so that the radial position of the friction portion 3 relative to the wheel body is fixed, improving the installation stability of the friction portion 3 with the first wheel body 1 and the second wheel body 2, and at the same time increasing the overall structural strength of the roller 50. Preferably, in the radial direction of the wheel body, the long groove 33 is located inside the tooth-shaped protrusion 31. In this way, the structural compactness of the roller 50 is improved.

[0058] Specifically, please refer to Figures 4 to 6 , in this embodiment, the first wheel body 1 includes a first support portion 13 and a first spacer portion 14. In the circumferential direction of the wheel body, the first spacer portion 14 is spaced from the first support portion 13.

In the circumferential direction of the wheel body, the second spacer portion 24 is spaced from the second support portion 23. A second installation groove 21 extending in the axial direction of the wheel body is formed between the second spacer portion 24 and the second support portion 23. The second installation groove 21 communicates with the first installation groove 11.

[0059] Optionally, please continue to refer to Figures 4 to 6 , the friction portion 3 includes two installation portions 32 respectively arranged on both sides of the long groove 33 in the circumferential direction of the wheel body; on the first wheel body 1, two first installation grooves 11 are provided corresponding to each first support portion 13. In the circumferential direction of the wheel body, the two first installation grooves 11 are respectively located on both sides of the first support portion 13, and the two first inclined surfaces 132 of each first support portion 13 are respectively connected between the first support surface 131 and the corresponding two first installation grooves 11; on the second wheel body 2, two second installation grooves 21 are provided corresponding to each second support portion 23.
