Description

Technical Field

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

[0002] Existing sheet media processing devices typically include a frame and a paper separating mechanism, a processing mechanism, and a conveying mechanism mounted on the frame. These mechanisms are arranged sequentially along the direction of movement of the sheet media. The paper separating mechanism includes a kicking roller, a separating roller, and a blocking roller. The kicking roller and the separating roller are arranged sequentially along the direction of movement of the sheet media. Both the kicking roller and the separating roller are used to drive the sheet media to move. The blocking roller is opposite to the separating roller and is used to prevent overlapping sheet media from entering between the blocking roller and the separating roller. The conveying mechanism includes a conveying roller, which drives the sheet media to continue moving towards the processing mechanism. The processing mechanism is used to perform processing such as identification or printing on the sheet media. To ensure sufficient spacing between adjacent sheets of sheet-like media so that the processing mechanism has enough time to process each sheet, existing technologies typically set the conveying speed of the conveying mechanism higher than that of the paper-splitting mechanism. The distance between the conveying roller and the paper-splitting roller is less than the length of the sheet-like media. This results in a situation where the front end of the sheet-like media is held by the conveying roller and the rear end by the paper-splitting roller. Because the conveying speed of the conveying roller on the sheet-like media is greater than that of the paper-splitting roller, the conveying roller and the paper-splitting roller may compete for the paper, potentially tearing the sheet-like media and causing losses to the user.

When the rotational speed of the fourth drive unit driven by the paper kicker roller is greater than that of the third drive unit, the fourth drive unit separates from the third drive unit.

[0025] As a preferred technical solution for the sheet-type media processing device, in the case where the second drive unit is fixedly connected to the paper separating roller and the fourth drive unit is fixedly connected to the paper kicking roller:

[0026] The paper separating roller includes a paper separating mandrel, which is connected to the frame and can rotate relative to the frame about its own axis.

[0029] The sheet-type media processing device provided by this utility model has at least the following beneficial effects:

[0030] This sheet-type media processing device includes a frame, a processing mechanism, a conveying mechanism, a paper separating mechanism, and a transmission mechanism. The processing mechanism, conveying mechanism, paper separating mechanism, and transmission mechanism are all mounted on the frame and arranged sequentially along the direction of movement of the sheet-type media. The processing mechanism is used to process the sheet-type media. The conveying mechanism includes a conveying roller, and the paper separating mechanism includes a kicking roller, a separating roller, and a blocking roller. Along the direction of movement of the sheet-type media, the kicking roller, separating roller, and conveying roller are arranged sequentially and are all used to drive the sheet-type media to move. The blocking roller is opposite the separating roller and is used to block... To prevent overlapping sheet-like media from entering between the paper-blocking roller and the paper-separating roller; the transmission mechanism includes a first motor, a first drive unit, and a second drive unit. The first drive unit is driven by the first motor and is used to drive the first drive unit to rotate relative to the frame. The second drive unit is fixedly or driven by the paper-separating roller. When the rotational speed of the first drive unit is greater than the rotational speed of the second drive unit, the first drive unit can abut against the second drive unit and drive the second drive unit to rotate synchronously relative to the frame. When the rotational speed of the second drive unit driven by the paper-separating roller is greater than the rotational speed of the first drive unit, the second drive unit separates from the first drive unit. With this configuration, when the sheet-like medium contacts the separating roller but has not yet moved to the conveyor roller, the first drive unit, driven by the first motor, abuts against the second drive unit and drives the separating roller to rotate, causing the separating roller to move the sheet-like medium. At this time, the sheet-like medium provides resistance to the separating roller, allowing the first and second drive units to remain in contact and transmit power. When the sheet-like medium moves to the conveyor roller but has not yet detached from the separating roller, the speed at which the conveyor roller drives the sheet-like medium is greater than the speed at which the separating roller drives the sheet-like medium. The sheet-like medium provides driving force to the separating roller, and under the drag of the sheet-like medium, the separating roller will rotate at the same speed as the conveyor roller, increasing the rotational speed of the separating roller. This, in turn, increases the rotational speed of the second drive unit, causing the rotational speed of the second drive unit to exceed that of the first drive unit. This causes the second drive unit to rotate relative to the first drive unit and separate from it, meaning the first motor exerts no force on the separating roller. This prevents the conveyor roller and the separating roller from competing for paper, thus avoiding tearing of the sheet-like medium. Attached Figure Description

[0048] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0049] Please refer to Figures 1 to 6This embodiment provides a sheet-like media processing device, which includes a frame 1, a processing mechanism 2, a conveying mechanism 3, a paper separating mechanism 4, and a transmission mechanism 5. The processing mechanism 2, conveying mechanism 3, paper separating mechanism 4, and transmission mechanism 5 are all disposed on the frame 1, and are arranged sequentially along the moving direction of the sheet-like media. The processing mechanism 2 is used to process the sheet-like media. The conveying mechanism 3 includes a conveying roller 31, and the paper separating mechanism 4 includes a kicking roller 41, a separating roller 42, and a blocking roller 43. Along the moving direction of the sheet-like media, the kicking roller 41, separating roller 42, and conveying roller 31 are arranged sequentially and are all used to drive the sheet-like media to move. The blocking roller 43 is opposite to the separating roller 42 and is used to prevent overlapping sheet-like media from entering between the blocking roller 43 and the separating roller 42. The transmission mechanism 5 includes a first motor 51, a first drive unit 52, and a second drive unit 53. The first drive unit 52 is connected to the first motor 51 for transmission. The first motor 51 is used to drive the first drive unit 52 to rotate relative to the frame 1. The second drive unit 53 is fixedly connected or transmitted to the paper separating roller 42. When the rotational speed of the first drive unit 52 is greater than the rotational speed of the second drive unit 53, the first drive unit 52 can abut against the second drive unit 53 and drive the second drive unit 53 to rotate synchronously relative to the frame 1. When the rotational speed of the second drive unit 53 driven by the paper separating roller 42 is greater than the rotational speed of the first drive unit 52, the second drive unit 53 separates from the first drive unit 52.

[0050] In the sheet media processing apparatus provided in this embodiment, when the sheet media contacts the separating roller 42 but has not yet moved to the conveying roller 31, the first driving unit 52, driven by the first motor 51, abuts against the second driving unit 53 and drives the separating roller 42 to rotate, causing the separating roller 42 to drive the sheet media to move. At this time, the sheet media provides resistance to the separating roller 42, so that the first driving unit 52 and the second driving unit 53 can always maintain contact and transmit power. When the sheet media moves to the conveying roller 31 but has not detached from the separating roller 42, the speed at which the conveying roller 31 drives the sheet media to move is greater than the speed at which the separating roller 42 drives the sheet media. The speed at which the sheet-like medium moves increases. The sheet-like medium provides driving force to the separating roller 42, and under the drag of the sheet-like medium, the separating roller 42 will rotate at the same speed as the conveying roller 31, increasing the rotational speed of the separating roller 42. Consequently, the separating roller 42 drives the second drive unit 53 to increase its rotational speed, causing the rotational speed of the second drive unit 53 to exceed that of the first drive unit 52. This causes the second drive unit 53 to rotate relative to the first drive unit 52 and separate from the first drive unit 52. In other words, the first motor 51 exerts no force on the separating roller 42, which can prevent the conveying roller 31 and the separating roller 42 from competing for paper, thereby avoiding the sheet-like medium from being torn.

[0051] Alternatively, please refer to Figure 1The processing mechanism 2 includes an image sensor 21 and a print head 22. Along the forward direction of the sheet-like medium, the image sensor 21 and the print head 22 are arranged in sequence. The image sensor 21 is used to collect image information of the sheet-like medium, and the print head 22 is used to print preset content on the sheet-like medium.

[0052] Alternatively, please refer to Figures 3 to 6 When the second drive unit 53 is fixedly connected to the paper separating roller 42, the transmission mechanism 5 also includes a transmission component that can rotate relative to the frame 1. The first drive unit 52 is integrally connected to the transmission component and forms an accommodating space 54 with the transmission component. The first drive unit 52 and the accommodating space 54 are arranged sequentially along the circumferential direction of the paper separating roller 42. The first drive unit 52 is connected to the first motor 51 via the transmission component. The second drive unit 53 is located within the accommodating space 54. When the rotational speed of the second drive unit 53 is greater than the rotational speed of the first drive unit 52, the second drive unit 53 can rotate relative to the transmission component around the axis of the paper separating roller 42 within the accommodating space 54. With this configuration, when the rotational speed of the second drive unit 53 is greater than the rotational speed of the first drive unit 52, the second drive unit 53 rotates within the accommodating space 54. The rotational range of the second drive unit 53 can be constrained by the accommodating space 54, resulting in a simple structure that is easy to implement.

[0053] It should be noted that in this embodiment, the first drive unit 52 has a first sidewall 521 and a second sidewall 522 along the circumferential direction of the paper separating roller 42. When the sheet-like medium contacts the paper separating roller 42 but has not yet moved to the conveying roller 31, such as Figure 5 As shown, the first sidewall 521 of the first drive unit 52 can abut against the second drive unit 53 and drive the second drive unit 53 to rotate synchronously relative to the frame 1; when the sheet-like medium moves to the conveyor roller 31 and has not detached from the separating roller 42, under the drag of the sheet-like medium, the second drive unit 53 rotates relative to the transmission member around the axis of the separating roller 42 within the accommodating space 54, and the second drive unit 53 gradually moves away from the first sidewall 521 and gradually moves closer to the second sidewall 522; when the sheet-like medium moves to the conveyor roller 31 and detaches from the separating roller 42, as Figure 6 As shown, the second drive unit 53 is spaced apart from the first side wall 521, and the second drive unit 53 is spaced apart from the second side wall 522. That is, when the sheet-like medium is separated from the paper separating roller 42, the second drive unit 53 and the second side wall 522 do not come into contact, and the second drive unit 53 will not affect the first motor's drive of the first drive unit 52.

[0054] Alternatively, please refer to Figure 3 and Figure 4 The rotation center of the first drive unit 52 coincides with the rotation center of the second drive unit 53. This arrangement improves the structural compactness of the transmission mechanism 5.

[0055] Alternatively, please refer to Figure 3 The paper separating roller 42 includes a paper separating core shaft 421 and a paper separating wheel 422 fixedly sleeved on the paper separating core shaft 421. The paper separating core shaft 421 is connected to the frame 1 and can rotate relative to the frame 1 around its own axis.

[0056] Alternatively, please refer to Figure 3 The transmission component is a first transmission wheel 55, which is sleeved on the paper-splitting core shaft 421 and can rotate relative to the paper-splitting roller 42 around the axis of the paper-splitting core shaft 421. The second drive unit 53 is fixedly connected to the paper-splitting core shaft 421. With this configuration, when the first motor 51 drives the first transmission wheel 55 to rotate, it will drive the first drive unit 52 to rotate synchronously. Furthermore, when the sheet-like medium contacts the paper-splitting roller 42 but has not yet moved to the conveyor roller 31, the first drive unit 52 drives the second drive unit 53 to drive the paper-splitting roller 42 to rotate synchronously around the axis of the paper-splitting core shaft 421. Additionally, directly sleeved the first transmission wheel 55 on the paper-splitting core shaft 421 and placing the first drive unit 52 and the accommodating space 54 on the first transmission wheel 55 results in a simple structure that is easy to implement. Preferably, the first transmission wheel 55 is a gear.

[0057] Optionally, refer to Figure 3 , Figure 5 and Figure 6 The first drive wheel 55 has a first circular groove 551 on its end face. The first drive part 52 is disposed in the first circular groove 551, and the surface of the first drive part 52 and the groove wall of the first circular groove 551 together form an accommodating space 54. This arrangement, with the first drive part 52 disposed in the first circular groove 551 on the end face of the first drive wheel 55, and the groove wall of the first circular groove 551 and the surface of the first drive part 52 forming the accommodating space 54, allows the second drive part 53 to abut against or rotate relative to the first drive part 52 within the first circular groove 551. The groove wall of the first circular groove 551 can restrict the relative position of the second drive part 53 and the first drive part 52, improving the reliability of the cooperation or relative rotation between the first drive part 52 and the second drive part 53. In other embodiments, the first drive part 52 may also protrude from the end face of the first drive wheel 55.

[0058] Optionally, refer to Figure 3 , Figure 5 and Figure 6 The second drive unit 53 is shaft-shaped and fixedly inserted into the paper separating core shaft 421, with its axis perpendicular to the axis of the paper separating core shaft 421. This configuration improves the reliability of the first drive unit 52 driving the paper separating roller 42 to rotate around its axis via the second drive unit 53. In other embodiments, the axis of the paper separating core shaft 421 and the axis of the second drive unit 53 can be set to other angles as needed; additionally, the second drive unit 53 can also be block-shaped and fixedly protruding from the outer peripheral surface of the paper separating core shaft 421.

[0059] Optionally, when the first drive unit 52 abuts against the second drive unit 53, the first drive unit 52 and the second drive unit 53 are in line contact. This arrangement improves the reliability of the first drive unit 52 driving the second drive unit 53 to rotate synchronously.

[0060] As one alternative, please refer to Figure 4 The transmission components include a first transmission shaft 62, a first gear 63, and a first connecting sleeve 64. The first transmission shaft 62 is supported by the frame 1 and can rotate around its own axis, and is coaxially arranged with the paper separating roller 42. The first gear 63 is fixedly sleeved to the first end of the first transmission shaft 62 and is drively connected to the first motor 51. The first connecting sleeve 64 is fixedly sleeved to the second end of the first transmission shaft 62. The first driving part 52 and the first connecting sleeve 64 form a receiving space 54. The transmission mechanism 5 also includes a second connecting sleeve 65, which is fixedly sleeved to the paper separating roller 42. The second driving part 53 is fixedly connected to the paper separating roller 42 through the second connecting sleeve 65. With this configuration, the first motor 51 drives the first driving part 52 to rotate sequentially through the first transmission wheel 55, the first transmission shaft 62, and the first connecting sleeve 64. The first driving part 52 then drives the paper separating roller 42 to rotate synchronously through the second driving part 53 and the second connecting sleeve 65. Specifically, the first connecting sleeve 64 has a first end face opposite to the second connecting sleeve 65, the second connecting sleeve 65 has a second end face opposite to the first connecting sleeve 64, the first driving part 52 protrudes from the first end face, and along the circumferential direction of the first connecting sleeve 64, the first driving part 52 occupies a part of the space of the first end face, the other part of the space of the first end face is empty and forms an accommodating space 54, and the second driving part 53 protrudes from the second end face and is inserted into the accommodating space 54.

[0061] As an alternative, in the case where the second drive unit 53 is fixedly connected to the paper separating roller 42, the transmission mechanism 5 further includes a transmission member that can rotate relative to the frame 1; the second drive unit 53 is integrally connected to the transmission member and forms an accommodating space 54 with the transmission member, the second drive unit 53 and the accommodating space 54 are arranged along the circumferential direction of the paper separating roller 42, the second drive unit 53 is fixedly connected to the paper separating roller 42 through the transmission member, and the first drive unit 52 is located within the accommodating space 54. When the rotational speed of the second drive unit 53 is greater than the rotational speed of the first drive unit 52, the first drive unit 52 can rotate relative to the transmission member around the axis of the paper separating roller 42 within the accommodating space 54. With this configuration, when the rotational speed of the second drive unit 53 is greater than the rotational speed of the first drive unit 52, the second drive unit 53 can still rotate within the accommodating space 54, and the relative position of the second drive unit 53 and the first drive unit 52 is restricted by the accommodating space 54.

[0062] Alternatively, please refer to Figure 8The transmission mechanism 5 also includes a third drive unit 56 and a fourth drive unit 57. The third drive unit 56 is driven by the first motor 51 and can rotate relative to the frame 1 under the drive of the first motor 51. The fourth drive unit 57 is fixedly or driven by the kick roller 41. When the rotational speed of the fourth drive unit 57 is less than the rotational speed of the third drive unit 56, the third drive unit 56 can abut against the fourth drive unit 57 and drive the fourth drive unit 57 to rotate synchronously relative to the frame 1. When the rotational speed of the fourth drive unit 57 driven by the kick roller 41 is greater than the rotational speed of the third drive unit 56, the fourth drive unit 57 separates from the third drive unit 56. This arrangement can effectively prevent the separating roller 42 and the kick roller 41 from competing with the conveying roller 31 for paper, thereby increasing the length range of sheet media suitable for this sheet media processing device. Preferably, the rotational speeds of the separating roller 42 and the kick roller 41 are the same under the drive of the first motor 51.

[0063] Specifically, along the conveying direction of the sheet-like medium, the distance between the separating roller 42 and the conveying roller 31 is L1, the distance between the kick roller 41 and the conveying roller 31 is L2, and the length of the sheet-like medium is L. When L1 < L < L2, when the front end of the sheet-like medium moves to the conveying roller 31, the rear end component of the sheet-like medium has not yet detached from the separating roller 42 and the kick roller 41; when L ≥ L2, when the front end of the sheet-like medium moves to the conveying roller 31, the rear end component of the sheet-like medium has not yet detached from the kick roller 41. For sheet media with a length greater than or equal to L2, when the front end of the sheet media just moves to the conveyor roller 31, the conveyor roller 31 drives the sheet media to move at a speed greater than that of the paper separating roller 42 and the paper kicking roller 41. As a result, the sheet media will drag the paper separating roller 42 and the paper kicking roller 41 to rotate at the same speed as the conveyor roller 31. Consequently, under the drive of the paper separating roller 42, the rotation speed of the second drive unit 53 is greater than that of the first drive unit 52, and the second drive unit 53 separates from the first drive unit 52. Furthermore, under the drive of the paper kicking roller 41, the rotation speed of the fourth drive unit 57 is greater than that of the third drive unit 56, and the fourth drive unit 57 separates from the third drive unit 56. This prevents the paper separating roller 42 and the paper kicking roller 41 from competing with the conveyor roller 31 for paper, thereby avoiding the sheet media from being torn.

[0064] Alternatively, please continue to refer to Figure 2 and Figure 8The kicking roller 41 includes a kicking core shaft 411, which is connected to the frame 1 and can rotate relative to the frame 1 around its own axis. When the second drive unit 53 is fixedly connected to the paper separating roller 42 and the fourth drive unit 57 is fixedly connected to the kicking roller 41, the transmission mechanism 5 also includes a second drive wheel 58 that is connected to the first motor 51. The second drive wheel 58 is sleeved with the kicking core shaft 411 and can rotate relative to the kicking roller 41 around the axis of the kicking core shaft 411. The end face of the second drive wheel 58 is provided with a second circular groove 581. The third drive unit 56 is connected to the second drive wheel 58 as a whole and is disposed in the second circular groove 581. The fourth drive unit 57 is fixedly connected to the kicking core shaft 411 and is located in the second circular groove 581. With this configuration, the third drive unit 56 is positioned within the second circular groove 581 on the end face of the second transmission wheel 58. The fourth drive unit 57 abuts against or rotates relative to the third drive unit 56 within the second circular groove 581. The groove wall of the second circular groove 581 restricts the relative position of the fourth drive unit 57 and the third drive unit 56, improving the reliability of the engagement or relative rotation between the fourth drive unit 57 and the third drive unit 56. Preferably, the second transmission wheel 58 is a gear, and the transmission mechanism 5 further includes a motor gear 60 and a transition gear 61. The motor gear 60 is fixedly sleeved with the output shaft of the first motor 51, and the transition gear 61 meshes with the motor gear 60. Both the first transmission wheel 55 and the second transmission wheel 58 mesh with the transition gear 61. More preferably, the fourth drive unit 57 is shaft-shaped, and the axis of the fourth drive unit 57 is perpendicular to the axis of the paper kicker roller 41. This configuration improves the reliability of the third drive unit 56 driving the paper kicker roller 41 to rotate along its axis via the fourth drive unit 57.

[0065] In other embodiments, the first transmission wheel 55 and the second transmission wheel 58 may both be configured as pulleys. The transmission mechanism 5 also includes a first transmission belt and a second transmission belt. The first transmission wheel 55 is connected to the first motor 51 via the first transmission belt, and the second transmission wheel 58 is connected to the first motor 51 via the second transmission belt.

[0066] Alternatively, please continue to refer to Figure 2 The sheet media processing device also includes a second motor 59, which is connected to the conveyor roller 31 and drives the conveyor roller 31 to rotate. This arrangement allows the conveying mechanism 3 and the paper separating mechanism 4 to be driven by different motors, facilitating individual control of the conveying mechanism 3 and the paper separating mechanism 4. For example, when the first sheet of sheet media moves to the conveyor roller 31 and disengages from the paper separating roller 42, the first motor 51 can be stopped. After the processing mechanism 2 has finished processing the first sheet of sheet media, the first motor 51 can be controlled to move again, so that the kicking roller 41 and the paper separating roller 42 drive the second sheet of sheet media to continue moving.

[0067] As one alternative, please refer to Figure 7 When the second drive unit 53 is connected to the paper separating roller 42, the transmission mechanism 5 also includes a second drive shaft 66, a second gear 67 and a third gear 68. The second drive shaft 66 is supported by the frame 1 and can rotate relative to the frame 1 around its own axis. The axis of the second drive shaft 66 is parallel to and spaced apart from the axis of the paper separating roller 42. The second gear 67 is fixedly sleeved with the second drive shaft 66 and is driven by the first motor 51. The first drive unit 52 is fixedly connected to the second drive shaft 66. The third gear 68 is sleeved on the second drive shaft 66 and can rotate relative to the second drive shaft 66 around its own axis. The third gear 68 is driven by the paper separating roller 42. The second drive unit 53 is connected to the third gear 68 as a whole and forms an accommodating space 54 with the third gear 68. The second drive unit 53 and the accommodating space 54 are arranged along the circumferential direction of the second drive shaft 66. The first drive unit 52 is located in the accommodating space 54. When the rotational speed of the second drive unit 53 is greater than the rotational speed of the first drive unit 52, the first drive unit 52 can rotate relative to the second drive unit 53 around the axis of the second drive shaft 66 in the accommodating space 54. With this configuration, the first motor 51 drives the paper separating roller 42 to rotate sequentially via the second gear 67, the second transmission shaft 66, the first drive unit 52, the second drive unit 53, and the third gear 68. Preferably, the end face of the third gear 68 is provided with a third circular groove 681, and the second drive unit 53 is disposed within the third circular groove 681, with the surface of the second drive unit 53 and the groove wall of the third circular groove 681 forming an accommodating space 54. More preferably, the first drive unit 52 is shaft-shaped and fixedly inserted into the second transmission shaft 66, with the axial direction of the first drive unit 52 perpendicular to the axial direction of the second transmission shaft 66.
