Description

Technical Field

[0001] This application relates to the field of paper cup production, and in particular to a paper sheet separation structure. Background Technology

[0002] In the paper cup manufacturing industry, stacked paper sheets need to be separated and transferred to the forming mechanism before the paper cups are formed. Currently, vertical suction mechanisms or planetary gear mechanisms are used to separate and transfer the paper sheets. However, in commonly used vertical suction mechanisms, the suction cups release air momentarily after adsorbing the paper sheet and moving to the designated position. Because the paper sheet was in a concave state due to the previous pressure difference, the sudden release of air causes the paper sheet to bounce slightly upwards, and the lack of constraint results in poor positional accuracy. While planetary gear mechanisms can be used to separate paper sheets, a single planetary gear mechanism requires three components: a sun gear, a planet carrier, and a gear ring. The coordination between components is cumbersome, the mechanical structure is complex, and maintenance is difficult, making it difficult to meet the requirements for efficient and stable paper sheet separation. Utility Model Content

[0003] Therefore, it is necessary to provide a paper separation structure that can achieve precise paper separation, high separation efficiency, and simple and easy maintenance to address the above problems.

[0004] This utility model provides a paper sheet separation structure, including:

[0005] Used for separating paper pieces, including:

[0006] Fixture;

[0007] The guide assembly includes a fixed wheel, a rotating wheel, and a fixed shaft. The fixed wheel and the fixed shaft are both fixedly mounted on the fixed frame. The rotating wheel is mounted on the fixed shaft and can reciprocate around the fixed shaft. The rotating wheel is connected to the fixed wheel in a transmission manner, so that the rotating wheel reciprocates around the fixed shaft while rotating around the axis of the rotating wheel, and has a material suction position and a material discharge position.

[0008] The feeding assembly includes a first receiving member and a second receiving member for receiving the paper sheet; and a suction assembly, which is disposed on the rotating wheel and can move together with the rotating wheel. In the suction position, the suction assembly can suction the paper sheet contained in the first receiving member, and in the discharging position, the suction assembly can place the suctioned paper sheet into the second receiving member.

[0009] This design provides a stable foundation for the installation of all subsequent components. In the guide assembly, the transmission connection between the fixed wheel and the rotating wheel allows the rotating wheel to maintain a specific posture throughout its movement, as it reciprocates around the fixed axis while simultaneously rotating around its own axis. The connection between the suction assembly and the rotating wheel ensures that the suction assembly completely follows the movement trajectory and posture changes of the rotating wheel, guaranteeing stable paper adsorption at the suction position and stable release at the discharge position. This reduces paper detachment or weak adsorption caused by unstable suction assembly movement, achieving precise paper separation. The placement assembly is divided into a first receiving component and a second receiving component, clearly defining the storage areas for the paper to be separated and the already separated paper.

[0010] In one embodiment, the axis of the fixed shaft coincides with the axis of the fixed wheel.

[0011] With this configuration, when the rotating wheel reciprocates around the fixed axis, the transmission distance between the rotating wheel and the fixed wheel remains consistent, avoiding transmission ratio fluctuations or transmission instability caused by axis misalignment.

[0012] In one embodiment, the guide assembly further includes a drive belt wound around the fixed wheel and the rotating wheel.

[0013] With this configuration, the transmission belt wraps around both the fixed and rotating pulleys, achieving a transmission connection between them. Compared to direct gear meshing, the transmission belt can buffer the impact force during transmission, reduce transmission noise, and avoid severe wear caused by direct gear contact.

[0014] In one embodiment, the paper separation structure further includes a connector disposed on the fixed shaft and capable of reciprocating about the fixed shaft, and a rotating wheel disposed on the connector and capable of rotating about the axis of the rotating wheel; the paper separation structure further includes a tensioning assembly, the tensioning assembly including a tensioning wheel, the tensioning wheel being disposed on the connector and pressing the outer side of the transmission belt near the fixed wheel.

[0015] This configuration provides a mounting platform for the rotating wheel, allowing it to both reciprocate around a fixed axis with the connecting component and rotate relative to the connecting component around its own axis. This achieves stable installation and motion transmission of the rotating wheel's combined motion. The tensioning wheel of the tensioning assembly presses against the outer side of the transmission belt near the fixed wheel, effectively adjusting the belt tension and preventing it from loosening due to long-term use or vibration during transmission.

[0016] In one embodiment, the transmission belt is located at both ends of the tensioning wheel, forming an angle α, the angle α being greater than or equal to 120°.

[0017] With this configuration, the included angle α formed by the transmission belt at both ends of the tensioner is greater than or equal to 120°, which ensures that there is sufficient contact area between the transmission belt and the tensioner.

[0018] In one embodiment, the paper separation structure further includes a drive assembly disposed on the fixed frame, the drive assembly being connected to the rotating wheel and capable of driving the rotating wheel to reciprocate around the fixed axis.

[0019] With this configuration, the drive component provides the power source for the reciprocating rotation of the rotating wheel around a fixed axis, so that the revolution of the rotating wheel does not require manual driving, thus automating the paper separation process.

[0020] In one embodiment, the driving assembly includes a driving source assembly and a transmission assembly. The transmission assembly includes a moving member and a connecting member. The connecting member is disposed on the fixed shaft and is capable of reciprocating around the fixed shaft. The rotating wheel is disposed on the connecting member and is capable of rotating around the axis of the rotating wheel. The driving source assembly is drively connected to one end of the moving member, and the connecting member is rotatably connected to the other end of the moving member. The driving source assembly can drive the moving member to reciprocate along a first preset direction, thereby driving the connecting member to drive the rotating wheel to reciprocate around the fixed shaft.

[0021] With this setup, the drive source component is responsible for providing power, and the transmission component is responsible for transmitting the power and converting it into the motion required to rotate the wheel. The motion conversion mechanism is simple and reliable, and the power transmission efficiency is high.

[0022] In one embodiment, the drive source assembly includes a drive shaft, a drive wheel, and a rotating component. The drive shaft is rotatably connected to the fixed frame, the drive wheel is eccentrically fixed to the drive shaft, one end of the rotating component is rotatably connected to the fixed frame, the other end is rotatably connected to the moving component, and the drive wheel is rotatably connected to the middle of the rotating component.

[0023] With this configuration, the drive source assembly, through the cooperation of the drive shaft, drive wheel, and rotating components, forms an eccentric wheel mechanism, realizing the generation and transmission of power. This eccentric wheel mechanism's motion conversion method is simple, compact, and low-cost, and can achieve continuous reciprocating motion.

[0024] In one embodiment, the first receiving member has a receiving surface for receiving the paper sheet, the receiving surface forming an acute angle with the horizontal plane.

[0025] This design tilts the stacked paper pieces on the receiving surface. Compared to horizontal placement, this tilt changes the pressure distribution between the paper pieces, reduces friction, and effectively reduces paper adhesion.

[0026] In one embodiment, the suction assembly includes a rotating member and a suction member, the rotating member being disposed on the rotating wheel, the suction member being disposed on the rotating member, and the number of suction members is at least one.

[0027] This configuration provides a stable mounting platform for the suction unit, allowing it to move synchronously with the rotating wheel and ensuring precise positioning during material suction and discharge. The number of suction units is set to at least one, which can be adjusted flexibly according to the size and weight of the paper. Attached Figure Description

[0038] In the paper cup manufacturing industry, stacked paper sheets need to be separated and transferred to the forming mechanism before the paper cups are formed. Currently, vertical suction mechanisms or planetary gear mechanisms are used to separate and transfer the paper sheets. However, in commonly used vertical suction mechanisms, the suction cups release air momentarily after adsorbing the paper sheet and moving to the designated position. Because the paper sheet was in a concave state due to the previous pressure difference, the sudden release of air causes the paper sheet to bounce slightly upwards, and the lack of constraint results in poor positional accuracy. While planetary gear mechanisms can be used to separate paper sheets, a single planetary gear mechanism requires three components: a sun gear, a planet carrier, and a gear ring. The coordination between components is cumbersome, the mechanical structure is complex, and maintenance is difficult, making it difficult to meet the requirements for efficient and stable paper sheet separation.

[0039] To solve the above problems, such as Figures 1 to 3 As shown, this utility model discloses a paper separation structure that can achieve precise paper separation, high separation efficiency, and simple and easy-to-maintain structure.

[0040] like Figure 1 and Figure 2 As shown, this application provides a paper separation structure for separating paper sheets 200, including a fixing frame 4, a guiding assembly 1, a feeding assembly 3, and a suction assembly 2. The guiding assembly 1 includes a fixed wheel 11, a rotating wheel 12, and a fixed shaft 13. The fixed wheel 11 and fixed shaft 13 are both fixedly mounted on the fixing frame 4. The rotating wheel 12 is mounted on the fixed shaft 13 and can reciprocate around the fixed shaft 13. The rotating wheel 12 is drive-connected to the fixed wheel 11, causing the rotating wheel 12 to reciprocate around the fixed shaft 13 while simultaneously rotating around its axis, and has a suction position and a discharge position. The feeding assembly 3 includes a first receiving member and a second receiving member 32 for accommodating the paper sheets 200. The suction assembly 2 is mounted on the rotating wheel 12 and can move with the rotating wheel 12. In the suction position, the suction assembly 2 can adsorb the paper sheets 200 contained in the first receiving member; in the discharge position, the suction assembly 2 can place the adsorbed paper sheets 200 into the second receiving member 32. The first accommodating member is used to accommodate the paper piece 200 to be separated, and the second accommodating member 32 is used to accommodate the paper piece 200 that has already been separated.

[0041] This configuration provides a stable foundation for the installation of all subsequent components, ensuring the overall stability of the structure during the separation process and preventing component movement deviations due to an unstable foundation, which could affect separation accuracy. In the guide assembly 1, the transmission connection between the fixed wheel 11 and the rotating wheel 12 allows the rotating wheel 12 to reciprocate around the fixed shaft 13 (revolution) while simultaneously rotating around its own axis (rotation). This combined motion ensures that the rotating wheel 12 maintains a specific posture throughout its movement. The connection design between the suction assembly 2 and the rotating wheel 12 allows the suction assembly 2 to completely follow the movement trajectory and posture changes of the rotating wheel 12, ensuring that the suction assembly 22 can stably adsorb the paper sheet 200 at the suction position and stably release it at the discharge position. This reduces the possibility of the paper sheet 200 falling off or being poorly adsorbed due to unstable movement of the suction assembly 2, achieving precise separation of the paper sheet 200. The feeding component 3 is divided into a first receiving component and a second receiving component 32, clearly defining the storage areas for the paper sheets 200 to be separated and those already separated. This avoids separation errors caused by the chaotic stacking of the paper sheets 200, and also provides clear target positions for the suction and discharge of the suction component 2, improving the orderliness of the separation process. The structural design of the entire paper sheet separation structure, through the reasonable layout and coordinated movement of each component, reduces the number of parts without affecting the transmission effect, reduces the impact of cumulative errors on transmission accuracy, and achieves precise and efficient separation of the paper sheets 200. Furthermore, the structure is relatively simple, reducing the difficulty of subsequent maintenance.

[0042] The distance between the rotating wheel 12 and the fixed shaft 13, i.e. the revolution radius of the rotating wheel 12, is determined according to the distance between the first accommodating member and the second accommodating member 32. The greater the distance between the first accommodating member and the second accommodating member 32, the larger the revolution radius of the rotating wheel 12.

[0043] like Figure 1 and Figure 2 As shown, in one embodiment, the axis of the fixed shaft 13 coincides with the axis of the fixed wheel 11. This arrangement ensures that when the rotating wheel 12 reciprocates (revolves) around the fixed shaft 13, the transmission distance between the rotating wheel 12 and the fixed wheel 11 remains consistent, preventing transmission ratio fluctuations or instability due to axis misalignment. Whether using gear meshing, synchronous belt drive, or other transmission methods, axis coincidence guarantees stable meshing or contact between transmission components, reduces transmission wear, extends the service life of transmission components, and ensures the coordination of the rotating wheel 12's rotational speed and revolution speed, further improving the accuracy of the suction component 2's movement. This ensures that the suction component 22 accurately aligns with the paper sheet 200 and the placement component 3 at the suction and placement positions, improving separation accuracy. Simultaneously, stable transmission reduces force fluctuations in various components, preventing damage due to excessive localized force, extending the overall structure's service life, and further improving the separation accuracy of the paper sheet 200 and the structural reliability.

[0044] Depending on actual needs, the fixed shaft 13 and the fixed wheel 11 can be formed separately or as a single piece.

[0045] In another embodiment, the axis of the fixed shaft 13 can be slightly offset from the axis of the fixed wheel 11, depending on the actual design requirements. For example, the fixed shaft 13 can be eccentrically arranged on the fixed wheel 11. The eccentric arrangement leaves the central area open, allowing for flexible arrangement of the center of gravity of the entire structure. Then, the meshing center distance is kept constant through connecting structures such as linkage assemblies and tensioning assemblies, avoiding changes in motion relationships caused by eccentricity.

[0046] like Figure 1 and Figure 2As shown, in one embodiment, the guide assembly 1 further includes a transmission belt 14, which is wound around the fixed wheel 11 and the rotating wheel 12. In the illustrated embodiment, the internal gear of the transmission belt 14 meshes with the external gears of the fixed wheel 11 and the rotating wheel 12. This arrangement, with the transmission belt 14 wound around the fixed wheel 11 and the rotating wheel 12, achieves a transmission connection between them. Compared to direct gear meshing, the transmission belt 14 can buffer the impact force during transmission, reduce transmission noise, and avoid severe wear caused by direct gear contact. In the illustrated embodiment, the internal gear of the transmission belt 14 meshes with the external gear of the fixed wheel 11 and the external gear of the rotating wheel 12, which is a synchronous belt drive. The synchronous belt drive has the characteristics of precise transmission ratio and no slippage, which can ensure that while the rotating wheel 12 reciprocates around the fixed shaft 13, the speed of its rotation around its own axis and its revolution speed maintain a precise coordination relationship. There will be no lag or advance of rotation due to transmission slippage, thereby ensuring the stability of the posture of the suction component 2 during the movement, ensuring that the suction component 22 can accurately pick up the paper 200 at the suction position and accurately release the paper 200 at the discharge position, thus improving the separation accuracy and efficiency.

[0047] In this embodiment, the transmission belt 14 is connected to the fixed pulley 11 and the rotating pulley 12 in an open-loop transmission configuration. In another embodiment, depending on the actual design requirements, the transmission belt 14 can be connected to the fixed pulley 11 and the rotating pulley 12 in other ways, such as cross or semi-cross transmission.

[0048] In another embodiment, the fixed wheel 11 and the rotating wheel 12 can be directly connected by other means such as gear train meshing.

[0049] like Figure 1 and Figure 2As shown, in one embodiment, the paper separation structure further includes a connector 522, which is disposed on the fixed shaft 13 and can reciprocate around the fixed shaft 13. A rotating wheel 12 is disposed on the connector 522 and can rotate around the axis of the rotating wheel 12. The paper separation structure also includes a tensioning assembly 6, which includes a tensioning wheel 61. The tensioning wheel 61 is disposed on the connector 522 and presses the outer side of the transmission belt 14 near the fixed wheel 11. In the illustrated embodiment, the tensioning wheel 61 is a bearing, and a tensioning shaft 62 that cooperates with the bearing is also included. The tensioning shaft 62 is fixedly disposed on the connector 522. This configuration provides a mounting carrier for the rotating wheel 12, allowing the rotating wheel 12 to both reciprocate around the fixed shaft 13 with the connector 522 (revolution) and rotate relative to the connector 522 around its own axis (rotation), achieving stable installation and motion transmission of the combined motion of the rotating wheel 12. The tensioning wheel 61 of the tensioning assembly 6 presses against the outer side of the transmission belt 14 near the fixed wheel 11, effectively adjusting the tension of the transmission belt 14 and preventing it from loosening due to long-term use or vibration during transmission, which could lead to slippage and affect transmission accuracy. In the illustrated embodiment, the tensioning wheel 61 uses a low-friction outer tensioning bearing. The bearing itself has rolling characteristics, allowing it to rotate with the transmission belt 14 while pressing it, reducing frictional resistance between the tensioning wheel 61 and the transmission belt 14, preventing accelerated wear of the transmission belt 14 due to sliding friction, and extending the service life of the transmission belt 14. The tensioning shaft 62 is fixed to the connecting member 522, providing a stable mounting base for the tensioning wheel 61, ensuring that the tensioning wheel 61 can continuously and stably apply pressure to the transmission belt 14, guaranteeing the stability and reliability of the transmission.

[0050] In another implementation, depending on actual design requirements, the tensioning wheel 61 can be designed as a floating wheel held by two disc springs or other tensioning structures that provide tension compensation for the extension and retraction of the transmission belt 14.

[0051] like Figure 1 and Figure 2As shown, in one embodiment, the transmission belt 14 forms an included angle α at both ends of the tensioner 61, where the included angle α is greater than or equal to 120°. Specifically, the included angle α can be designed to be, for example, 120°, 130°...160°. This arrangement, with the included angle α at both ends of the tensioner 61 greater than or equal to 120°, ensures sufficient contact area between the transmission belt 14 and the tensioner 61. According to the principle of friction, the larger the contact area, the greater the frictional force between the tensioner 61 and the transmission belt 14, thus better transmitting the tension force and preventing slippage of the transmission belt 14 during transmission. Sufficient contact area also allows the tension force to be evenly distributed across the contact section of the transmission belt 14, avoiding excessive local stress on the transmission belt 14 due to insufficient local contact area, which could lead to accelerated wear or deformation, and extending the service life of the transmission belt 14. At the same time, a larger included angle α can also ensure that the transmission belt 14 maintains a stable transmission trajectory under the action of the tensioning wheel 61, reduce the risk of the transmission belt 14 running off course, ensure the stability and accuracy of the transmission, and thus ensure the accuracy of the compound motion of the rotating wheel 12, and improve the accuracy and efficiency of the suction component 2 in separating the paper 200.

[0052] In another implementation, the included angle α can be designed to be other angles less than 120°, depending on the actual design requirements.

[0053] In another implementation, depending on actual design requirements, the tensioning pulley 61 can be designed with an adjustable angle α, allowing it to tilt within a certain range to further optimize the contact angle α with the transmission belt 14.

[0054] like Figures 1 to 3 As shown, in one embodiment, the paper separation structure further includes a drive assembly 5 disposed on the fixed frame 4. The drive assembly 5 is connected to the rotating wheel 12 and can drive the rotating wheel 12 to reciprocate around the fixed axis 13. This configuration provides the power source for the reciprocating rotation of the rotating wheel 12 around the fixed axis 13, eliminating the need for manual drive of the rotating wheel 12's revolution and automating the paper separation process. The connection between the drive assembly 5 and the rotating wheel 12 results in a shorter power transmission path and less power loss, ensuring efficient transmission of drive torque to the rotating wheel 12, enabling the rotating wheel 12 to reciprocate stably and reliably. Compared to manual drive, the automated drive method not only saves labor costs but also ensures consistent and stable speed, frequency, and angle of the rotating wheel 12's reciprocating rotation, avoiding fluctuations in separation accuracy caused by differences in manual operation, and improving the stability and efficiency of the paper separation process. Meanwhile, the drive component 5 is mounted on the fixed frame 4, forming an integral structure with the fixed frame 4, which facilitates the overall installation, debugging and movement of the paper separation structure, and improves the integration and practicality of the paper separation structure.

[0055] like Figures 1 to 3As shown, in one embodiment, the drive assembly 5 includes a drive source assembly 51 and a transmission assembly 52. ​​The transmission assembly 52 includes a moving member 523 and a connecting member 522. The connecting member 522 is disposed on the fixed shaft 13 and can reciprocate around the fixed shaft 13. The rotating wheel 12 is disposed on the connecting member 522 and can rotate around the axis of the rotating wheel 12. The drive source assembly 51 is drively connected to one end of the moving member 523, and the connecting member 522 is rotatably connected to the other end of the moving member 523. The drive source assembly 51 can drive the moving member 523 to reciprocate along a first preset direction, thereby driving the connecting member 522 to drive the rotating wheel 12 to reciprocate around the fixed shaft 13. With this configuration, the drive assembly 5 is divided into a drive source assembly 51 and a transmission assembly 52, with a clear division of labor. The drive source assembly 51 is responsible for providing power, and the transmission assembly 52 is responsible for transmitting power and converting it into the motion form required by the rotating wheel 12. The connecting member 522 of the transmission assembly 52 provides a mounting carrier for the rotating wheel 12 and also serves as a transmission component to transmit motion, enabling the rotating wheel 12 to reciprocate around the fixed axis 13 together with the connecting member 522, thus achieving revolution. The moving member 523 reciprocates along a first preset direction, and through its rotational connection with the connecting member 522, converts the linear reciprocating motion into the reciprocating rotational motion of the connecting member 522 around the axis. The motion conversion mechanism is simple and reliable, and has high power transmission efficiency. This structural design makes the installation position of the drive source assembly 51 more flexible, eliminating the need for direct alignment with the rotating wheel 12. It can be adjusted according to the spatial layout of the fixed frame 4 and the installation positions of other components, improving the overall structural layout flexibility. At the same time, by controlling the movement speed and stroke of the moving member 523 driven by the drive source assembly 51, the rotation speed and angle of the connecting member 522 can be precisely controlled, thereby precisely controlling the revolution parameters of the rotating wheel 12 and improving the accuracy of paper separation 200.

[0056] In the illustrated implementation scheme, the first preset direction is vertical. In another implementation scheme, depending on actual design requirements, the first preset direction can also be designed as horizontal or other directions.

[0057] In one embodiment, the transmission assembly 52 further includes a connecting shaft 521, which is fixedly disposed on one of the connecting member 522 and the movable member 523, with the other member sleeved on the connecting shaft 521. In the illustrated embodiment, the connecting shaft 521 is fixedly disposed on the connecting member 522, and the movable member 523 is sleeved on the connecting shaft 521 and can drive the connecting shaft 521 to drive the connecting member 522 to reciprocate. This configuration provides a concrete way to achieve a rotational connection between the connecting member 522 and the movable member 523, making the rotational connection between them more stable and reliable. The structure of the connecting shaft 521 being fixed on one and sleeved on the other ensures that the relative rotation between the two can only occur around the axis of the connecting shaft 521, with a fixed motion trajectory, avoiding relative wobbling or offset, and improving the accuracy of motion transmission. In the illustrated embodiment, the connecting shaft 521 is fixed to the connector 522, and the moving part 523 is sleeved on the connecting shaft 521. The reciprocating motion of the moving part 523 can be precisely transmitted to the connector 522 through the connecting shaft 521, causing the connector 522 to rotate reciprocally around the fixed shaft 13. The power transmission path is clear, and the power loss is small. This structure is easy to process and install. The connecting shaft 521 can be integrally formed with the fixed part or fixed by simple fixing methods such as welding or threaded connection. The sleeved part only needs to have holes that match the connecting shaft 521, which reduces the processing difficulty and installation cost. At the same time, the presence of the connecting shaft 521 also facilitates subsequent maintenance. When wear occurs, the connecting shaft 521 or the sleeved part can be replaced separately without replacing the entire connector 522 or moving part 523, reducing maintenance costs.

[0058] In another embodiment, the connecting shaft 521 is fixedly disposed on the moving member 523, and the connecting member 522 is sleeved on the connecting shaft 521. The moving member 523 drives the connecting member 522 to reciprocate through the connecting shaft 521.

[0059] like Figures 1 to 3As shown, in one embodiment, the drive source assembly 51 includes a drive shaft 511, a drive wheel 512, and a rotating component 513. The drive shaft 511 is rotatably connected to the fixed frame 4. The drive wheel 512 is eccentrically fixed to the drive shaft 511. One end of the rotating component 513 is rotatably connected to the fixed frame 4, and the other end is rotatably connected to the moving component 523. The drive wheel 512 is rotatably connected to the middle of the rotating component 513. With this configuration, the drive source assembly 51 generates and transmits power through the cooperation of the drive shaft 511, the drive wheel 512, and the rotating component 513. The drive shaft 511, rotatably connected to the fixed frame 4, provides stable rotational support for the drive wheel 512. The drive wheel 512, eccentrically fixed to the drive shaft 511, causes the center of the drive wheel 512 to rotate around the axis of the drive shaft 511 when the drive shaft 511 rotates, thereby driving the rotating component 513 to oscillate back and forth around a fixed point at one end. The other end of the rotating component 513 is rotatably connected to the moving component 523, converting the reciprocating oscillation into the reciprocating linear motion of the moving component 523 along a first preset direction. This motion conversion method of the eccentric wheel mechanism is simple, compact, and low in cost, and can achieve continuous reciprocating motion, making it suitable for providing continuous power to the transmission component 52. Simultaneously, the stroke of this structure can be changed by adjusting the eccentricity of the drive wheel 512. The larger the eccentricity, the greater the oscillation amplitude of the rotating component 513 and the longer the stroke of the moving component 523. This allows adjustment of the revolution angle of the rotating wheel 12, adapting to the separation requirements of different specifications of paper sheets 200 and improving the versatility of the paper sheet separation structure.

[0060] In another implementation, the drive source component 51 may be other drive structures such as crank-slider, gear rack, etc., depending on the actual design requirements.

[0061] like Figure 1 and Figure 2As shown, in one embodiment, the first receiving member has a receiving surface for receiving paper sheets 200, which forms an acute angle with the horizontal plane. It should be noted that the receiving surface refers to the thickness direction of the stacked paper sheets 200. This arrangement, with the receiving surface of the first receiving member forming an acute angle with the horizontal plane, causes the paper sheets 200 stacked on the receiving surface to be in an inclined state. Compared to horizontal placement, this inclined state changes the pressure distribution between the paper sheets 200. When placed horizontally, the lower layer of paper sheets 200 bears the weight of all the upper layer of paper sheets 200, resulting in greater pressure and a higher risk of the paper sheets 200 sticking together due to excessive friction. However, when placed inclined, the component of the gravity of the upper layer of paper sheets 200 along the normal direction of the receiving surface decreases, and the pressure on the lower layer of paper sheets 200 decreases accordingly. This reduces the friction between the paper sheets 200, effectively reducing the sticking of the paper sheets 200 and ensuring that the suction member 22 can accurately absorb a single paper sheet 200 at the suction position, thus improving the stability of the suction quantity. Meanwhile, the inclined receiving surface can also utilize the weight of the paper sheet 200 to keep the paper sheet 200 always close to the lower end of the receiving surface, ensuring the stability of the stacked paper sheets 200 and preventing the paper sheets 200 from being scattered due to operational vibration. This ensures that the suction component 22 can accurately pick up the paper sheet 200 each time, improving the suction efficiency. In addition, the smaller adhesive force of the inclined receiving surface can also ensure that the suction component 2 picks up only one paper sheet 200 at a time.

[0062] In the illustrated embodiment, the second receiving member 32 is parallel to the horizontal plane, so the angle between the receiving surface of the first receiving member and the horizontal plane is the angle between the receiving surface of the first receiving member and the second receiving member 32. The larger the angle between the receiving surface of the first receiving member and the second receiving member 32, the larger the angle that the rotating wheel 12 needs to rotate, and the larger the tooth ratio between the fixed wheel 11 and the rotating wheel 12.

[0063] In another embodiment, depending on actual design requirements, the second receiving member 32 can be arranged in other directions such as forming an acute angle with the horizontal plane.

[0064] The angle between the receiving surface of the first receiving member and the horizontal plane can be selected according to actual needs, such as 35°, 45°, etc. In another embodiment, the angle between the receiving surface of the first receiving member and the horizontal plane can be designed as an adjustable structure.

[0065] Furthermore, the first receiving component near the lower end of the paper sheet 200 can be designed as a corrugated structure to provide multiple layers of support for the paper sheet 200 and avoid the impact of the gravity of the paper sheet 200 on the suction operation.

[0066] In addition, an air blowing device can be added to the opposite side of the suction member 22. Even if paper pieces 200 stick together, air blowing can separate the paper pieces 200 to ensure that only one paper piece 200 is separated at a time.

[0067] like Figure 1 and Figure 2 As shown, in one embodiment, the suction assembly 2 includes a rotating member 21 and a suction member 22. The rotating member 21 is disposed on the rotating wheel 12, and the suction member 22 is disposed on the rotating member 21, with at least one suction member 22. In the illustrated embodiment, there are two suction members 22, which are spaced apart on the rotating member 21 along a direction perpendicular to the axis of the rotating wheel 12. This arrangement provides a stable mounting carrier for the suction members 22, allowing them to move synchronously with the rotating wheel 12 and ensuring accurate positioning of the suction members 22 during material suction and discharge. The fact that there is at least one suction member 22 allows for flexible adjustment based on the size and weight of the paper sheet 200, preventing insufficient or uneven suction from a single suction member 22 that could cause the paper sheet 200 to fall off. In the illustrated embodiment, the two suction members 22 are spaced apart along a direction perpendicular to the axis of the rotating wheel 12, enabling them to adsorb different areas of the paper sheet 200 respectively. This increases the adsorption area and makes the adsorption force distribution more uniform, reducing wrinkles or displacement of the paper sheet 200 due to uneven force during transfer and improving adsorption stability. This spacing arrangement can also accommodate paper sheets 200 of different widths. By adjusting the distance between the two suction members 22, the adsorption requirements of paper sheets 200 of different sizes can be met, improving the versatility of the paper separation structure.

[0068] like Figure 1 and Figure 2 As shown, in one embodiment, the rotating wheel 12 is clamped and fixed to the rotating component 21 by a clamp 15. This clamping method allows for detachable fixing of the rotating wheel 12 and the rotating component 21. Compared to welding or integral molding, this method is more convenient for disassembly and installation, facilitating subsequent maintenance, replacement, or repositioning of the rotating wheel 12 or the rotating component 21. The clamp 15 applies clamping force through bolts or other fasteners, ensuring a tight fit between the rotating wheel 12 and the rotating component 21, preventing relative rotation or axial movement, and ensuring that the rotation and revolution of the rotating wheel 12 are accurately transmitted to the rotating component 21, thereby driving the suction component 22 to move stably. Furthermore, the clamping force of the clamp 15 can be adjusted by adjusting the tightness of the fasteners, adapting to different diameters of the rotating wheel 12 or rotating component 21 installation locations. This improves the adaptability and flexibility of the structure, eliminating the need for separate fixing structures for different specifications of parts and reducing processing and maintenance costs.

[0069] In another embodiment, depending on actual design requirements, the rotating wheel 12 can be fixed to the rotating component 21 by other structures such as keyway mating.

[0070] like Figure 1 and Figure 2As shown, in one embodiment, the rotating wheel 12 is fixedly mounted to the rotating component 21 by a locking nut 16. This configuration allows the locking nut 16 to be simple in structure, low in cost, and easy to install and disassemble. It enables detachable fixing between the rotating wheel 12 and the rotating component 21, facilitating subsequent maintenance, replacement, or position adjustment of the rotating wheel 12. The locking nut 16 applies axial pressure through a threaded connection, tightly fixing the rotating wheel 12 to a preset position on the rotating component 21. This prevents axial movement or loosening of the rotating component 21 during its movement with the rotating wheel 12, ensuring the stability of the positions of each component and thus guaranteeing the accuracy of the compound motion of the rotating wheel 12. Simultaneously, by adjusting the tightness of the locking nut 16, the installation gap between the rotating wheel 12 and the rotating component 21 can be appropriately compensated, reducing motion deviations caused by the gap.

[0071] In another embodiment, depending on actual design requirements, the rotating wheel 12 can be fixed to the rotating component 21 by means of other structures such as pins or snap-fits.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
