Description

Technical Field

[0001] This utility model relates to the technical field of sheet media processing equipment, and in particular to a sheet media processing device. Background Technology

[0002] Existing sheet media processing devices include a frame, a processing mechanism, and a paper separating mechanism. The processing mechanism is used to perform operations such as printing, scanning, or magnetic reading and writing on sheet media. The paper separating mechanism is used to transport multiple stacked sheet media one by one to the processing device. The paper separating mechanism includes a kicking roller, a separating roller, and a blocking roller set on the frame. The kicking roller and the separating roller are arranged sequentially along the direction of the sheet media's movement, and both are used to drive the sheet media in contact with them forward. The blocking roller is fixedly set on the frame and is opposite to the separating roller. The blocking roller is used to prevent overlapping sheet media from entering the processing mechanism, so that the sheet media passes through the processing mechanism one by one for processing operations. During the paper separation process, the thin sheet-like media driven by the separating roller enters the space between the separating roller and the paper blocking roller, generating sliding friction with the paper blocking roller. Since the paper blocking roller is fixedly connected to the frame, the contact area between the paper blocking roller and the thin sheet-like media is fixed. The repeated friction of different thin sheet-like media entering the space between the separating roller and the paper blocking roller on the same part of the paper blocking roller will cause severe wear on the contact area of ​​the paper blocking roller with the thin sheet-like media. This reduces the frictional resistance of the paper blocking roller to the thin sheet-like media, making it easier for overlapping thin sheet-like media to enter the processing mechanism, resulting in poor paper separation effect and requiring frequent replacement of the paper blocking roller, which is costly. Utility Model Content

[0003] The purpose of this invention is to provide a sheet-type media processing device that can increase the number of contact points between the paper-blocking roller and the sheet-type media, thereby reducing the replacement frequency of the paper-blocking roller, extending the service life of the paper-blocking roller, and improving the economy of the sheet-type media processing device.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A sheet-like media processing device includes a frame and a paper separating assembly and a limiting member disposed on the frame. The paper separating assembly includes a kicking roller, a separating roller, and a blocking roller. The kicking roller and the separating roller are arranged sequentially along the moving direction of the sheet-like media. The blocking roller is detachably disposed on the frame and is arranged opposite to the separating roller. The blocking roller has N mounting positions relative to the frame, and the contact portion between the blocking roller and the sheet-like media entering between the separating roller and the blocking roller is different at different mounting positions. The limiting member is used to cooperate with the blocking roller located at any of the mounting positions and prevent the blocking roller from rotating relative to the frame. Wherein, N is a positive integer greater than or equal to 2.

[0006] As an optional technical solution, the N mounting positions of the paper-blocking roller include a first mounting position and a second mounting position. The paper-blocking roller includes a first mounting portion and a second mounting portion arranged at intervals along its circumference. The paper-blocking roller also includes a first contact portion and a second contact portion arranged at intervals along its circumference. The limiting member includes a first limiting portion. When the paper-blocking roller is located in the first mounting position, the first limiting portion cooperates with the first mounting portion, and the sheet-like medium entering between the paper-splitting roller and the paper-blocking roller contacts the first contact portion. When the paper-blocking roller is located in the second mounting position, the first limiting portion cooperates with the second mounting portion, and the sheet-like medium entering between the paper-splitting roller and the paper-blocking roller contacts the second contact portion.

[0007] As an optional technical solution, the paper-blocking roller includes a mandrel, and the first mounting portion and the second mounting portion are respectively disposed on the outer peripheral surface of the mandrel as a first mounting surface and a second mounting surface; the limiting member is provided with a limiting groove with an opening, and the first limiting portion is a first limiting surface formed by the inner wall of the limiting groove; when the paper-blocking roller is located in the first mounting position, the mandrel is installed in the limiting groove through the opening, and the first mounting surface and the first limiting surface are in contact; when the paper-blocking roller is located in the second mounting position, the mandrel is installed in the limiting groove through the opening, and the second mounting surface and the first limiting surface are in contact.

[0008] As an optional technical solution, when the paper-blocking roller is located in the first mounting position or the second mounting position, the first limiting surface extends along the thickness direction of the sheet-like medium, and the paper-blocking roller can slide along the thickness direction of the sheet-like medium to approach or move away from the paper-separating roller, and the paper-blocking roller is configured to always have a tendency to move closer to the paper-separating roller.

[0009] As an optional technical solution, the paper-blocking roller further includes an abutting part and two paper-blocking wheels. The two paper-blocking wheels are both sleeved on the mandrel and are spaced apart. The paper-blocking wheels are used to contact the sheet-like medium. The abutting part is disposed on the mandrel and is located between the two paper-blocking wheels. The abutting part includes a first abutting surface and a second abutting surface disposed along the circumferential direction of the mandrel.

[0010] The sheet-like media processing device further includes a pressing member, which is movably connected to the frame and can slide relative to the frame along the thickness direction of the sheet-like media. When the paper-blocking roller is in the first installation position, the pressing member abuts against the first contact surface. When the paper-blocking roller is in the second installation position, the pressing member abuts against the second contact surface. Under the action of elastic force and / or gravity, the pressing member always has a tendency to drive the paper-blocking roller closer to the paper-separating roller.

[0011] Alternatively, the sheet-type media processing device may further include an elastic element connected to the frame. When the paper-blocking roller is in the first mounting position, the elastic element abuts against the first contact surface, so that the paper-blocking roller always has a tendency to move closer to the paper-separating roller. When the paper-blocking roller is in the second mounting position, the elastic element abuts against the second contact surface, so that the paper-blocking roller always has a tendency to move closer to the paper-separating roller.

[0012] As an optional technical solution, the limiting member further includes a second limiting surface formed by the inner wall of the limiting groove, the second limiting surface being opposite to and spaced apart from the first limiting surface; when the paper-blocking roller is located in the first mounting position, the second limiting surface is in contact with the second mounting surface, and when the paper-blocking roller is located in the second mounting position, the second limiting surface is in contact with the first mounting surface.

[0013] As an optional technical solution, the first mounting surface and the second mounting surface are arranged opposite to each other and parallel to each other. The limiting member includes two opposing and spaced elastic hooks, forming the opening and the limiting groove between the two elastic hooks. Each elastic hook includes an elastic arm and a buckle. The first end of the elastic arm is fixedly connected to the frame, and the buckle is disposed at the second end of the elastic arm. Under the action of external force, the second end of the elastic arm can generate elastic deformation relative to the first end of the elastic arm. When the paper-blocking roller is located in the first mounting position or the second mounting position, the buckle of each elastic hook engages with the mandrel to prevent the mandrel from disengaging from the limiting groove through the opening.

[0014] As an optional technical solution, the cross-section of the mandrel is a regular polygon.

[0015] As an optional technical solution, both the first mounting part and the second mounting part are plate-shaped or block-shaped, and the first limiting part is groove-shaped. When the paper-blocking roller is located in the first mounting position, the first mounting part is inserted into the first limiting part to prevent the paper-blocking roller from rotating relative to the frame. When the paper-blocking roller is located in the second mounting position, the second mounting part is inserted into the first limiting part to prevent the paper-blocking roller from rotating relative to the frame.

[0016] Alternatively, both the first mounting portion and the second mounting portion are groove-shaped, and the first limiting portion is plate-shaped or block-shaped. When the paper-blocking roller is in the first mounting position, the first limiting portion is inserted into the first mounting portion to prevent the paper-blocking roller from rotating relative to the frame. When the paper-blocking roller is in the second mounting position, the first limiting portion is inserted into the second mounting portion to prevent the paper-blocking roller from rotating relative to the frame.

[0017] As an optional technical solution, the N mounting positions of the paper-blocking roller include a first mounting position and a second mounting position. The paper-blocking roller includes a third mounting portion and further includes a first contact portion and a second contact portion arranged at intervals along its circumference. The limiting member includes a second limiting portion and a third limiting portion. When the paper-blocking roller is located in the first mounting position, the third mounting portion cooperates with the second limiting portion to prevent the paper-blocking roller from rotating relative to the frame, and the sheet-like medium entering between the paper-separating roller and the paper-blocking roller contacts the first contact portion. When the paper-blocking roller is located in the second mounting position, the third mounting portion cooperates with the third limiting portion to prevent the paper-blocking roller from rotating relative to the frame, and the sheet-like medium entering between the paper-separating roller and the paper-blocking roller contacts the second contact portion.

[0018] The beneficial effects of this utility model are:

[0019] This utility model discloses a sheet-like media processing device, which includes a frame and a paper separating assembly and a limiting member disposed on the frame. The paper separating assembly includes a kicking roller, a separating roller, and a blocking roller. The kicking roller and the separating roller are arranged sequentially along the moving direction of the sheet-like media. The blocking roller is detachably disposed on the frame and is arranged opposite to the separating roller. The blocking roller has N installation positions relative to the frame. The contact parts between the blocking roller located at different installation positions and the sheet-like media entering between the separating roller and the blocking roller are different. The limiting member is used to cooperate with the blocking roller at any installation position and prevent the blocking roller from rotating relative to the frame. Wherein, N is a positive integer greater than or equal to 2. This sheet media handling device has N mounting positions for its paper-blocking roller. When wear occurs at the point where the paper-blocking roller contacts the sheet media, it can be switched to another mounting position, thereby changing the contact point between the paper-blocking roller and the sheet media. This extends the service life of the paper-blocking roller, eliminating the need to replace it with a new one. This reduces the replacement frequency of the paper-blocking roller as a consumable part, thus effectively reducing costs. Attached Figure Description

[0038] Example 1

[0039] like Figures 1 to 8 As shown, this embodiment provides a sheet-like media processing device, which includes a frame 10 and a paper separating assembly and a limiting member disposed on the frame 10. The paper separating assembly includes a kicking roller 21, a separating roller 22, and a blocking roller 23. Along the moving direction of the sheet-like media, the kicking roller 21 and the separating roller 22 are arranged sequentially. The blocking roller 23 is detachably disposed on the frame 10 and is arranged opposite to the separating roller 22. The blocking roller 23 has N installation positions relative to the frame 10. The contact portion between the blocking roller 23 located at different installation positions and the sheet-like media entering between the separating roller 22 and the blocking roller 23 is different. The limiting member is used to cooperate with the blocking roller 23 at any installation position and prevent the blocking roller 23 from rotating relative to the frame 10. Wherein, N is a positive integer greater than or equal to 2.

[0040] In this embodiment, the paper-stopping roller 23 and the paper-separating roller 22 are arranged opposite to each other. The limiting member can cooperate with the paper-stopping roller 23 and prevent the paper-stopping roller 23 from rotating relative to the frame 10. The paper-kicking roller 21 and the paper-separating roller 22 can drive the sheet-like medium to move. When the sheet-like medium moves to the paper-separating roller 22 and the paper-stopping roller 23, it will contact the corresponding position of the paper-stopping roller 23, thereby causing wear at that position of the paper-stopping roller 23. After wear occurs at the part of the paper-stopping roller 23 that contacts the sheet-like medium, the paper-stopping roller 23 can be removed and its installation position relative to the frame 10 can be adjusted. This can adjust the contact part between the paper-stopping roller 23 and the sheet-like medium, thereby changing the paper-stopping roller 23 from a single-use roller to a multi-use roller. This can effectively extend the service life of the paper-stopping roller 23 without replacing it with a new one, reducing the replacement frequency of the paper-stopping roller 23 as a consumable part and reducing costs.

[0041] Optionally, in this embodiment, the paper-blocking roller 23 has N installation positions relative to the frame 10. That is to say, compared with the previous paper-blocking roller 23, the service life of the paper-blocking roller 23 in this embodiment is N times that of the previous paper-blocking roller 23, which will not be elaborated here.

[0042] Preferably, such as Figure 1 As shown, in this embodiment, the sheet-like media processing device further includes an image sensor 200 and a print head 100. Along the forward direction of the sheet-like media, the paper separating assembly, the image sensor 200, and the print head 100 are arranged in sequence. The image sensor 200 is used to collect image information of the sheet-like media, and the print head 100 is used to print preset content on the sheet-like media.

[0043] Furthermore, the N mounting positions of the paper-blocking roller 23 include a first mounting position and a second mounting position. The paper-blocking roller 23 includes a first mounting portion and a second mounting portion arranged at intervals along its circumference. The paper-blocking roller 23 also includes a first contact portion and a second contact portion arranged at intervals along its circumference. The limiting member includes a first limiting portion. When the paper-blocking roller 23 is located in the first mounting position, the first limiting portion cooperates with the first mounting portion, and the sheet-like medium entering between the paper-splitting roller 22 and the paper-blocking roller 23 contacts the first contact portion. When the paper-blocking roller 23 is located in the second mounting position, the first limiting portion cooperates with the second mounting portion, and the sheet-like medium entering between the paper-splitting roller 22 and the paper-blocking roller 23 contacts the second contact portion.

[0044] In this embodiment, the first limiting part can selectively cooperate with the first mounting part or the second mounting part, so that the paper blocking roller 23 can be switched to the first mounting position or the second mounting position. When the paper blocking roller 23 is in the first mounting position, the sheet-like medium contacts the first contact part of the paper blocking roller 23. When the paper blocking roller 23 is in the second mounting position, the sheet-like medium contacts the second contact part of the paper blocking roller 23. The first contact part and the second contact part are arranged at intervals along the circumference of the paper blocking roller 23, so that the first contact part and the second contact part set at different positions of the paper blocking roller 23 can contact the sheet-like medium respectively. Thus, while ensuring the functionality of the paper blocking roller 23, the service life of the paper blocking roller 23 is significantly improved, thereby effectively reducing costs.

[0045] Furthermore, such as Figures 5 to 7 As shown, the paper-blocking roller 23 includes a spindle 24, a first mounting portion and a second mounting portion, which are respectively a first mounting surface 241 and a second mounting surface 242 spaced apart on the outer peripheral surface of the spindle 24; the limiting member is provided with a limiting groove 31 with an opening, and the first limiting portion is a first limiting surface 33 formed by the inner wall of the limiting groove 31; when the paper-blocking roller 23 is in the first mounting position, the spindle 24 is installed in the limiting groove 31 through the opening, and the first mounting surface 241 and the first limiting surface 33 are in contact; when the paper-blocking roller 23 is in the second mounting position, the spindle 24 is installed in the limiting groove 31 through the opening, and the second mounting surface 242 and the first limiting surface 33 are in contact.

[0046] In this embodiment, as Figure 7 and Figure 8 As shown, by selectively attaching the first limiting surface 33 to the first mounting surface 241 or the second mounting surface 242 to prevent the paper blocking roller 23 from rotating relative to the frame 10, the paper blocking roller 23 can be limited to the first mounting position or the second mounting position. The structure is simple and easy to implement, and the surface attachment setting can improve the limiting effect of the first limiting surface 33 on the first mounting surface 241 or the second mounting surface 242, thereby ensuring the performance of the paper blocking roller 23 and the performance of the sheet media processing device.

[0047] Preferably, in this embodiment, as Figure 4As shown, two limiting components are provided, spaced apart on the frame 10. Two sets of first mounting surfaces 241 and second mounting surfaces 242 are respectively provided at both ends of the mandrel 24. The two limiting components and the two sets of first mounting surfaces 241 and second mounting surfaces 242 are configured in a one-to-one correspondence, so that both ends of the mandrel 24 can be detachably installed in the two limiting grooves 31 of the two limiting components. When the paper-blocking roller 23 is in the first installation position, the two first limiting surfaces 33 of the two limiting components are respectively in contact with the two first mounting surfaces 241 at both ends of the mandrel 24. When the paper-blocking roller 23 is in the second installation position, the two first limiting surfaces 33 of the two limiting components are respectively in contact with the two second mounting surfaces 242 at both ends of the mandrel 24. This configuration improves the limiting effect on the mandrel 24, thereby improving the limiting effect on the paper-blocking roller 23, and thus improving the stability of the installation position of the paper-blocking roller 23, effectively ensuring the performance of the paper-blocking roller 23 during use.

[0048] In this embodiment, when the paper-stopping roller 23 is located in the first mounting position or the second mounting position, the first limiting surface 33 extends along the thickness direction of the sheet-like medium, and the paper-stopping roller 23 can slide along the thickness direction of the sheet-like medium to approach or move away from the paper-separating roller 22. The paper-stopping roller 23 is configured to always have a tendency to move closer to the paper-separating roller 22. In this embodiment, when the paper-stopping roller 23 is located in the first mounting position or the second mounting position, it can float relative to the frame 10 along the thickness direction of the sheet-like medium, allowing the gap between the paper-stopping roller 23 and the paper-separating roller 22 to automatically adapt to sheet-like media of different thicknesses. Furthermore, the paper-stopping roller 23 always has a tendency to press the sheet-like medium against the paper-separating roller 22, ensuring the friction between the paper-stopping roller 23 and the sheet-like medium and improving the paper-stopping reliability of the paper-stopping roller 23.

[0049] Furthermore, such as Figure 5 and Figure 6 As shown, the paper-blocking roller 23 also includes an abutment portion 25 and two paper-blocking wheels 26. The two paper-blocking wheels 26 are both sleeved on the spindle 24 and are spaced apart. The paper-blocking wheels 26 are used to contact thin sheet media. The two paper-blocking wheels 26 are provided with a first contact portion and a second contact portion. The abutment portion 25 is provided on the spindle 24 and is located between the two paper-blocking wheels 26. The abutment portion 25 includes a first abutment surface 251 and a second abutment surface 252 arranged along the circumferential direction of the spindle 24. The sheet media processing device also includes a pressing member 41, which is movably connected to the frame 10 and can slide relative to the frame 10 along the thickness direction of the sheet media. When the paper-blocking roller 23 is in the first installation position, the pressing member 41 abuts against the first contact surface 251. When the paper-blocking roller 23 is in the second installation position, the pressing member 41 abuts against the second contact surface 252. Under the action of elastic force and / or gravity, the pressing member 41 always has the tendency to drive the paper-blocking wheel 26 closer to the paper-separating roller 22.

[0050] In this embodiment, the arrangement of two paper-blocking rollers 26 can improve the blocking effect on sheet-like media, improve the force balance of sheet-like media, and improve the performance of sheet-like media processing device. The abutment part 25 is disposed on the spindle 24 and is located between the two paper-blocking rollers 26. When the paper-blocking roller 23 is in the first installation position, the pressing member 41 can abut against the first abutment surface 251 of the abutment part 25. When the paper-blocking roller 23 is in the second installation position, the pressing member 41 can abut against the second abutment surface 252 of the abutment part 25. Thus, in any installation position, the paper-blocking roller 26 has a tendency to move closer to the paper-separating roller 22, thereby ensuring the paper separation effect.

[0051] Preferably, in this embodiment, as Figure 8 As shown, when the paper-stopping roller 23 is in the first mounting position, the first contact surface 251 is perpendicular to the thickness direction of the sheet-like medium; when the paper-stopping roller 23 is in the second mounting position, the second contact surface 252 is perpendicular to the thickness direction of the sheet-like medium. This arrangement ensures that the force applied by the pressing member 41 to the paper-stopping roller 23 is along the thickness direction of the sheet-like medium, improving the reliability of the paper-stopping roller 23 pressing against the paper-separating roller 22 and ensuring the paper-stopping reliability of the paper-stopping roller 23.

[0052] Preferably, such as Figure 6 As shown, each paper-stopping roller 26 includes a roller body 261 integrally formed with the spindle 24 and a damping sleeve 262 sleeved on the roller body 261. Along the axial direction of the spindle 24, the abutment portion 25 is centrally disposed between the two roller bodies 261. The damping sleeve 262 is used to contact thin sheet-like media. The first contact portion and the second contact portion are both disposed on the damping sleeve 262. This arrangement improves the uniformity of the force applied by the abutment portion 25 to the two paper-stopping rollers 26, ensuring the paper-stopping reliability of the paper-stopping roller 23.

[0053] Preferably, such as Figure 8 As shown, the pressing member 41 includes a pressing shaft, the axis of which extends along the thickness direction of the sheet-like medium. The sheet-like medium processing device also includes a compression spring 42 connected to the frame 10. The compression spring 42 is sleeved on the pressing shaft and compressed between the pressing member 41 and the frame 10. It is used to drive the pressing member 41 to always abut against the first contact surface 251 or the second contact surface 252, so that the paper-blocking roller 26 always has a tendency to move close to the paper-separating roller 22.

[0054] Optionally, in another embodiment, the sheet media processing apparatus further includes an elastic element connected to the frame 10. When the paper-stopping roller 23 is in the first mounting position, the elastic element abuts against the first contact surface 251, so that the paper-stopping roller 26 always has a tendency to move closer to the paper-separating roller 22. When the paper-stopping roller 23 is in the second mounting position, the elastic element abuts against the second contact surface 252, so that the paper-stopping roller 26 always has a tendency to move closer to the paper-separating roller 22. This arrangement also ensures that the paper-stopping roller 26 always has a tendency to move closer to the paper-separating roller 22 through the elastic force of the elastic element, thereby ensuring the paper separation effect.

[0055] Furthermore, such as Figure 7 As shown, the limiting component also includes a second limiting surface 34 formed by the inner wall of the limiting groove 31. The second limiting surface 34 is opposite to and spaced apart from the first limiting surface 33. When the paper blocking roller 23 is in the first mounting position, the second limiting surface 34 is in contact with the second mounting surface 242. When the paper blocking roller 23 is in the second mounting position, the second limiting surface 34 is in contact with the first mounting surface 241.

[0056] In this embodiment, when the paper-blocking roller 23 is in the first mounting position, the second limiting surface 34 is in contact with the second mounting surface 242, and the first mounting surface 241 is in contact with the first limiting surface 33. When the paper-blocking roller 23 is in the second mounting position, the second limiting surface 34 is in contact with the first mounting surface 241, and the second mounting surface 242 is in contact with the first limiting surface 33. This ensures the positional stability of the paper-blocking roller 23 in the first and second mounting positions, thereby improving the reliability of the limiting component in preventing the paper-blocking roller 23 from rotating relative to the frame 10 and improving the performance of the paper-blocking roller 23.

[0057] Furthermore, such as Figure 7 As shown, the first mounting surface 241 and the second mounting surface 242 are arranged opposite to each other and parallel to each other. The limiting member includes two opposite and spaced elastic hooks, forming an opening and a limiting groove 31 between the two elastic hooks. The elastic hook includes an elastic arm 32 and two buckles 35. The first end of the elastic arm 32 is fixedly connected to the frame 10, and the buckle 35 is disposed at the second end of the elastic arm 32. Under the action of external force, the second end of the elastic arm 32 can generate elastic deformation relative to the first end of the elastic arm 32. When the paper blocking roller 23 is in the first mounting position or the second mounting position, the buckle 35 of each elastic hook is engaged with the mandrel 24 to prevent the mandrel 24 from disengaging from the limiting groove 31 through the opening.

[0058] In this embodiment, when installing the paper-blocking roller 23, the second ends of the two elastic arms 32 are driven away from each other by external force, which increases the opening and facilitates the placement of the mandrel 24 in the limiting groove 31. After the external force is removed, the two elastic arms 32 are reset, so that the first limiting surface 33 is in contact with one of the first mounting surface 241 and the second mounting surface 242, and the second limiting surface 34 is in contact with the other of the first mounting surface 241 and the second mounting surface 242. The two buckles 35 are simultaneously engaged with the mandrel 24, thereby ensuring the installation stability of the mandrel 24. This setting not only facilitates the installation and disassembly of the paper-blocking roller 23, but also further improves the stability of the paper-blocking roller 23 installed on the frame 10 by the setting of the buckles 35.

[0059] In other embodiments, the limiting member includes a fixed block fixedly connected to the frame 10, with the limiting groove 31 and the opening both formed in the fixed block. The limiting member also includes a baffle connected to the fixed block by fasteners. The baffle is used to close at least a portion of the opening and prevent the mandrel 24 from disengaging from the limiting groove 31, and can also ensure the installation stability of the paper-stopping roller 23.

[0060] Preferably, such as Figure 4 As shown, the frame 10 is provided with an open mounting groove 500. The paper-blocking roller 23 and the limiting member are both disposed in the mounting groove 500. The sheet media processing device also includes a cover plate 300 movably connected to the frame 10. The cover plate 300 is provided with a clearance hole 400. The cover plate 300 has an open position and a closed position relative to the frame 10. When the cover plate 300 is in the open position, the cover plate 300 opens the opening and the opening is opposite to the opening. When the cover plate 300 is in the closed position and the paper-blocking roller 23 is in any mounting position, the cover plate 300 closes the opening and the paper-blocking roller 23 extends through the clearance hole 400 and is opposite to the paper-separating roller 22. This design allows for easy maintenance when the paper-blocking roller 23 wears down and the contact area between the paper-blocking roller 23 and the sheet-like medium needs adjustment. The cover plate 300 can be moved to the open position to remove the spindle 24 of the paper-blocking roller 23 through the opening and the limiting groove 31. The paper-blocking roller 23 can then be rotated around its axis by a set angle and reinstalled in the limiting groove 31.

[0061] Furthermore, such as Figure 7 As shown, the cross-section of the mandrel 24 is a regular polygon. In this embodiment, N is 6, and the cross-section of the mandrel 24 is a regular hexagon, giving the paper-stopping roller 23 six mounting positions relative to the frame 10. In other embodiments, N equals 4, and the cross-section of the mandrel 24 is a square, giving the paper-stopping roller 23 four mounting positions relative to the frame 10; or, N equals 8, and the cross-section of the mandrel 24 is a regular octagon, giving the paper-stopping roller 23 eight mounting positions relative to the frame 10. No limitation is imposed here.

[0062] Optionally, in this embodiment, the value of N is an even number, which ensures that the two opposite sides of the mandrel 24 are always parallel. At the same time, the two elastic arms 32 are set to be parallel and spaced apart. This setting facilitates the first limiting surface 33 of the limiting member to fit with one of the first mounting surface 241 and the second mounting surface 242, and the second limiting surface 34 of the limiting member to fit with the other of the first mounting surface 241 and the second mounting surface 242, thereby improving the installation stability of the mandrel 24.

[0063] Alternatively, in another embodiment, N can also be an odd number. When N is odd, the corresponding set elastic arm 32 is set at an angle, which can also make the first limiting surface 33 of the limiting member fit with one of the first mounting surface 241 and the second mounting surface 242, and the second limiting surface 34 of the limiting member fit with the other of the first mounting surface 241 and the second mounting surface 242, thereby ensuring the installation stability of the spindle 24. No specific limitations are made here.

[0064] Example 2

[0065] This embodiment provides a sheet-like media processing device. The difference between this sheet-like media processing device and the sheet-like media processing device in Embodiment 1 lies in the specific structures of the first mounting part, the second mounting part, and the first limiting part.

[0066] Specifically, both the first mounting part and the second mounting part are plate-shaped or block-shaped, and the first limiting part is groove-shaped. When the paper-blocking roller 23 is in the first mounting position, the first mounting part is inserted into the first limiting part to prevent the paper-blocking roller 23 from rotating relative to the frame 10. When the paper-blocking roller 23 is in the second mounting position, the second mounting part is inserted into the first limiting part to prevent the paper-blocking roller 23 from rotating relative to the frame 10. Alternatively, both the first mounting part and the second mounting part are groove-shaped, and the first limiting part is plate-shaped or block-shaped. When the paper-blocking roller 23 is in the first mounting position, the first limiting part is inserted into the first mounting part to prevent the paper-blocking roller 23 from rotating relative to the frame 10. When the paper-blocking roller 23 is in the second mounting position, the first limiting part is inserted into the second mounting part to prevent the paper-blocking roller 23 from rotating relative to the frame 10.

[0067] In this embodiment, the above-mentioned arrangement allows one of the first mounting part and the second mounting part to be inserted into the first limiting part, which can also realize the installation of the paper blocking roller 23 in the first mounting position or the second mounting position, and prevent the paper blocking roller 23 from rotating relative to the frame 10, thereby improving the installation stability of the paper blocking roller 23.

[0068] Example 3

[0069] This embodiment provides a sheet-like media processing device, which differs from the sheet-like media processing device in that it further includes a third mounting part.

[0070] Specifically, in this embodiment, the N mounting positions of the paper-blocking roller 23 include a first mounting position and a second mounting position. The paper-blocking roller 23 includes a third mounting portion and also includes a first contact portion and a second contact portion arranged at intervals along its circumference. The limiting member includes a second limiting portion and a third limiting portion. When the paper-blocking roller 23 is located in the first mounting position, the third mounting portion cooperates with the second limiting portion to prevent the paper-blocking roller 23 from rotating relative to the frame 10, and the sheet-like medium entering between the paper-separating roller 22 and the paper-blocking roller 23 contacts the first contact portion. When the paper-blocking roller 23 is located in the second mounting position, the third mounting portion cooperates with the third limiting portion to prevent the paper-blocking roller 23 from rotating relative to the frame 10, and the sheet-like medium entering between the paper-separating roller 22 and the paper-blocking roller 23 contacts the second contact portion.

[0071] In this embodiment, the sheet-like media processing device achieves the switching of the paper-blocking roller 23 between the first installation position and the second installation position by adjusting the third mounting part to cooperate with the second limiting part or the third limiting part. This makes the structure of the paper-blocking roller 23 simpler and reduces the production cost of the paper-blocking roller 23.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
