Description

Technical Field

[0001] This utility model relates to the field of automatic paper feeding technology, and in particular to a paper feeding component and an image forming device. Background Technology

[0002] During the operation of the scanning device, users can choose between two paper placement methods according to their actual needs: one is to open the flip cover and place the paper directly into the scanning area for scanning; the other is to use the paper feeding mechanism for automatic paper feeding. The paper guide in the flip cover guides the paper from the scanning area to the output path. However, when the flip cover is opened, only one side is supported, and after prolonged use, the flip cover is prone to bending and deformation, which in turn affects the deformation of the paper guide. When the flip cover is closed, the relative position between the deformed paper guide and other paper feeding parts changes, causing the paper guide to deviate from its preset position. This results in the paper easily colliding with the end of the paper guide during transport, causing paper jams, which in turn affects the normal operation of the equipment and the scanning and copying quality. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a paper feeding assembly that can accurately control the structural position of the paper guide, reducing the possibility of paper jams.

The cover is disposed on the upper side of the scanning platform, and the upper surface of the cover has a paper output platform located on the side of the paper guide step facing away from the scanning area. The paper output platform has a first guide surface. The paper feeding device is disposed on the upper side of the cover and has a second guide surface, the second guide surface being connected to the first guide surface. The paper guide is positioned between the paper guide step and the paper output platform and is connected to the paper output platform. The paper guide has a third guide surface that is opposite to the second guide surface. The third guide surface cooperates with the second guide surface to guide the paper away from the scanning area. The driving member is connected to the paper guide. The end of the paper guide facing the paper guide step is the first end, and the end of the paper guide step facing the paper guide is the second end. The driving member can drive the first end to move downward relative to the paper output platform so that the first end is lower than the second end.

[0006] The paper feeding assembly according to the embodiments of the present utility model has at least the following beneficial effects:

[0007] The paper feeding assembly of this utility model involves placing a paper guide between the paper guide step and the paper output platform, and connecting it to the paper output platform.

[0015] The paper guide has a first state and a second state. When the paper guide is in the first state, the second wall surface abuts against the lower end of the first wall surface to restrict the paper guide from continuing to rotate downward. When the paper guide is in the second state, the second wall surface abuts against the upper end of the first wall surface to restrict the paper guide from continuing to rotate upward.

[0016] According to some embodiments of the present invention, the first guide surface and the third guide surface are inclined, and the end of the first guide surface facing the third guide surface is lower than the end of the third guide surface facing the first guide surface.

[0047] 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.

[0048] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0050] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0051] The market offers a wide variety of printers, multifunction printers, and copiers, typically comprising a scanning platform and a paper feeding mechanism. The paper feeding mechanism has a hinged cover, with one side of the scanning platform rotatably connected to it. Users can choose between two paper placement methods: one is to open the cover and place the paper directly into the scanning area; the other is to use the paper feeding mechanism for automatic paper feeding. The paper guide within the hinged cover guides the paper from the scanning area to the output path. However, when the cover is open, only one side is supported, and over time, the cover is prone to bending and deformation, affecting the paper guide. When the cover is closed, the relative position of the deformed paper guide changes compared to other paper feeding components, causing the paper guide to detach from its preset position. This results in paper easily colliding with the end of the paper guide during transport, causing paper jams and affecting the normal operation of the equipment and the quality of scanning and copying.

[0052] Therefore, some embodiments of this utility model propose a paper feeding assembly 1000, suitable for image forming equipment 2000, wherein, with reference to Figure 1 As shown, the image forming device 2000 includes a paper feeding assembly 1000 and a scanning platform 2100. The scanning platform 2100 has a scanning area 2200, and one side of the scanning area 2200 has a paper guide step 100 that protrudes upward from the scanning platform 2100. (See reference for details.) Figures 1 to 14 The paper feeding assembly 1000 is described below.

[0053] Reference Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment of the present invention, the paper feeding assembly 1000 includes a hinged cover 200, a paper feeding device 400, a paper guide 500, and a driving component 600. The hinged cover 200 is located on the upper side of the scanning platform 2100, and one side of the hinged cover 200 is rotatably connected to one side of the scanning platform 2100. The hinged cover 200 can be rotated open relative to the scanning platform 2100. Specifically, the scanning platform 2100 is provided with a scanning area 2200 and a scanning plane area 2300. (Refer to...) Figure 2As shown, when the cover 200 is placed on the scanning platform 2100, paper can be fed into the scanning area 2200 through the paper feeding device 400. (Refer to...) Figure 1 As shown, when the cover 200 is rotated open relative to the scanning platform 2100, the scanning plane area 2300 is exposed, and paper can be directly placed into the scanning plane area 2300; the upper surface of the cover 200 is provided with a paper output platform 300, which is located on the side of the paper guide step 100 facing away from the scanning area 2200 and is fixedly connected to the cover 200.

[0054] Reference Figure 3 , Figure 4 and Figure 5 As shown, the paper feeding device 400 is located on the upper side of the cover 200 and is fixedly connected to the cover 200. Specifically, the paper feeding device 400 can cover the upper side of the paper guide 500 and the paper output platform 300, and is spaced apart from the paper guide 500 and the paper output platform 300. The lower side of the paper feeding device 400 is provided with a second guide surface 410, which is inclined upward along the direction of the paper guide step 100 toward the paper output platform 300.

[0055] Reference Figure 5 As shown, the paper guide 500 is disposed between the paper guide step 100 and the output table 300, and is connected to the output table 300. It can be understood that the side of the paper guide step 100 facing away from the scanning area 2200 connects to the paper guide 500, and the side of the paper guide 500 facing away from the paper guide step 100 connects to the output table 300. In this embodiment, the relative position of the paper guide 500 and the output table 300 can be changed. Specifically, they can be connected movably using fasteners, elastically using elastic elements, or through other forms of connection.

[0056] Reference Figure 4 and Figure 5 As shown, in this embodiment, the paper guide 500 has a third guide surface 511 on its upper side, which is opposite to the second guide surface 410. The third guide surface 511 and the second guide surface 410 cooperate to guide the paper away from the scanning area 2200. The paper output table 300 has a first guide surface 311 on its upper side, which is opposite to the second guide surface 410. The second guide surface 410 and the first guide surface 311 cooperate to guide the paper to move away from the paper feeding assembly 1000. Specifically, the side of the third guide surface 511 facing away from the scanning area 2200 is connected to the first guide surface 311. The second guide surface 410 is respectively spaced apart from the third guide surface 511 and the first guide surface 311, thereby forming a paper feeding channel 900, which can guide the paper to move.

[0057] In one example, the paper feeder 400 feeds paper to the scanning area 2200. After the paper is scanned, it comes into contact with the third guide surface 511 and enters the paper feed channel 900 under its guidance. Then, it leaves the scanning area 2200 along the third guide surface and then leaves the paper feed assembly 1000 along the first guide surface 311.

[0058] Reference Figure 6 and Figure 11 As shown, in this embodiment, the driving component 600 is connected to the paper guide component 500 and can be used to drive the paper guide component 500 so that the paper guide component 500 can move relative to the paper output table 300. In this embodiment, the driving component 600 can be an elastic element, a motor, a cylinder or other component with a driving function.

[0059] Reference Figure 4 and Figure 5 As shown, in this embodiment, the end of the paper guide 500 facing the paper guide step 100 is the first end 520, and the end of the paper guide step 100 facing the paper guide 500 is the second end 110. Specifically, the left end of the paper guide 500 is the first end 520, and the right end of the paper guide step 100 is the second end 110. The driving member 600 can drive the first end 520 to move downward relative to the paper output table 300, so that the first end 520 is lower than the second end 110.

[0060] For example, the paper guide step 100 has an abutment surface 120, which is lower than the second end 110. The paper guide step 100 is connected to the paper guide member 500 on the side facing away from the scanning area 2200. The first end 520 of the paper guide member 500 moves downward under the drive of the drive member 600 and directly abuts against the abutment surface 120 of the paper guide step 100, so that the first end 520 is lower than the second end 110. This prevents the paper from contacting the first end 520 after passing through the paper guide step 100. For example, but not limited to, the paper can directly contact the third guide surface 511 instead of the first end 520. This embodiment ensures that the first end 520 is always located lower than the second end 110 by accurately controlling the relative position between the paper guide member 500 and the paper guide step 100, thereby reducing the possibility of the paper passing through the second end 110 colliding with the first end 520.

[0061] It is understandable that by placing the paper guide 500 between the paper guide step 100 and the paper output platform 300, and connecting it to the paper output platform 300, and placing the paper feeding device 400 on the upper side of the cover 200, the third guide surface 511 of the paper guide 500 cooperates with the second guide surface 410 of the paper feeding device 400 to guide the paper away from the scanning area 2200, so that the paper can smoothly transition between the second guide surface 410 and the first guide surface 311. The second guide surface 410 of the paper feeding device 400 cooperates with the first guide surface 311 of the paper output platform 300 to guide the paper movement, thereby realizing paper output; the drive 600 is connected to the paper guide 500 and can drive the paper guide. The first end 520 of the paper guide 500 moves downward relative to the paper output table 300, so that the first end 520 of the paper guide 500 is always lower than the second end 110 of the paper guide step 100. Based on this, the drive unit 600 can accurately control the relative position of the paper guide 500 and the paper guide step 100, ensuring that the paper can smoothly contact the third guide surface 511 without colliding with the first end 520, reducing the possibility of paper jams, thereby ensuring the stability and accuracy of the paper during the paper feeding process, greatly reducing the phenomenon of paper shaking and impact during the paper feeding process, and thus improving the image quality of the paper after scanning.

[0062] Reference Figure 6 and Figure 11 As shown in this embodiment of the invention, the driving member 600 is an elastic member, disposed between the paper guide 500 and the paper output platform 300. The driving member 600 can drive the paper guide 500 to rotate or move downward relative to the paper output platform 300. Specifically, the side of the paper guide 500 facing the paper output platform 300 is movably connected to the side of the paper output platform 300 facing the paper guide 500. The driving member 600 is connected between the paper guide 500 and the paper output platform 300. One end of the driving member 600 is connected to or abuts against the paper guide 500, and the other end is connected to or abuts against the paper output platform 300. Under the action of the driving member 600, the paper guide 500 can rotate or move downward relative to the paper output platform 300.

[0063] It is understood that, in this embodiment, even if the paper guide 500 undergoes bending deformation, the elastic element can accurately drive the first end 520 of the paper guide 500 to abut against the abutment surface 120 of the paper guide step 100, thereby effectively controlling the relative position of the paper guide 500 and the paper output table 300, ensuring that the paper can smoothly pass through the paper feeding channel 900. In this embodiment, the elastic element can be a spring, a rubber component, a bellows, or other similar components.

[0064] Reference Figure 6 and Figure 7As shown in this embodiment of the utility model, a connecting plate 530 is provided at one end of the paper guide 500 facing the paper output table 300. A relief groove 320 is formed on the lower side of the paper output table 300. The connecting plate 530 passes through the relief groove 320. The driving member 600 is provided between the connecting plate 530 and the bottom wall of the relief groove 320. A limiting block 330 is provided on the lower side of the paper output table 300. The limiting block 330 can abut against the lower side of the paper guide 500 to restrict the connecting plate 530 from disengaging from the relief groove 320.

[0065] Specifically, refer to Figure 7 and Figure 8 As shown, in this embodiment, the paper output platform 300 is installed on the upper side of the flip cover 200. The paper guide 500 is connected to the paper output platform 300 on the side facing the paper output platform 300. One end of the paper guide 500 facing the paper output platform 300 protrudes to form a connecting plate 530, and the periphery of the connecting plate 530 protrudes upward and surrounds a first groove 531. The lower side of the paper output platform 300 is provided with a relief groove 320 corresponding to the connecting plate 530, and the connecting plate 530 is movably inserted into the relief groove 320. The driving member 600 is disposed between the connecting plate 530 and the bottom wall of the relief groove 320, that is, between the bottom wall of the first groove 531 and the bottom wall of the relief groove 320, thereby driving the paper guide 500 to move downward or rotate downward relative to the paper output platform 300.

[0066] Reference Figure 6 and Figure 7 As shown, a limiting block 330 protrudes from the lower side of the end of the paper output platform 300 facing the paper guide 500. The limiting block 330 restricts the connecting plate 530 from disengaging from the relief groove 320. This can be understood as limiting the maximum downward movement of the paper guide 500 relative to the paper output platform 300, thereby ensuring the relative position and structural stability of the paper guide 500 and the paper output platform 300, and reducing the possibility of the paper guide 500 dislodging.

[0067] Reference Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment of the present invention, the connecting plate 530 is provided with a guide hole 532, and a guide post 340 is formed by protruding from the bottom wall of the clearance groove 320. The guide post 340 passes through the guide hole 532. Specifically, a guide hole 532 is formed by protruding upward from the bottom wall of the first groove 531 of the connecting plate 530. The guide hole 532 is an oblong hole. A guide post 340 corresponding to the guide hole 532 is formed by protruding from the bottom wall of the clearance groove 320. The guide post 340 can be movably passed through the guide hole 532, thereby restricting the movement direction of the guide post 340, and thus accurately controlling the movement trajectory of the paper guide 500.

[0068] Reference Figure 6 , Figure 7 and Figure 8As shown, in this embodiment of the present invention, the driving component 600 is a spring 700, which is sleeved on the guide post 340. Specifically, one end of the spring 700 abuts against the bottom wall of the relief groove 320, and the other end abuts against the bottom wall of the first groove 531 of the connecting plate 530. The guide post 340 is movably inserted through the guide hole 532 of the connecting plate 530. It can be understood that the spring 700 has good elasticity and stable stiffness. It deforms when subjected to external force and returns to its original shape after the external force is removed, thereby achieving the functions of buffering, vibration reduction, and energy storage. Therefore, the spring 700 is connected to the paper guide 500. When the spring 700 switches from a tense state to a relaxed state, it can drive the paper guide 500 to move downward relative to the paper output table 300, that is, the first end 520 of the paper guide 500 moves downward relative to the paper output table 300, so that the first end 520 of the paper guide 500 is lower than the second end 110 of the paper guide step 100.

[0069] Reference Figure 6 , Figure 7 and Figure 8 As shown, in one example, a connecting plate 530, a spring 700, and a clearance groove 320 constitute a driving assembly. Two driving assemblies are provided and spaced apart along the length of the paper guide 500. When the paper guide 500 is driven by the driving member 600, the driving stress is evenly distributed, thereby ensuring the overall movement direction and stability of the paper guide 500. Two limiting blocks 330 are provided and spaced apart along the length of the paper output table 300. When the lower side of the paper guide 500 abuts against the limiting block 330, the paper guide 500 is stably restrained, thereby preventing the paper guide 500 from detaching from the paper feeding assembly 1000.

[0070] To achieve a downward tendency for the paper guide 500 relative to the output table 300, the spring 700 needs to be pre-compressed upwards during assembly to generate downward elastic potential energy. This elastic potential energy serves as the driving force, storing the driving force for the downward movement of the paper guide 500 relative to the output table 300. When the cover 200 is closed, the paper guide 500 can tightly abut against the contact surface 120 that creates the step, making the first end 520 lower than the second end 110. Based on this, the drive unit 600 can accurately control the relative position of the paper guide 500 and the paper guide step 100, ensuring that the paper can smoothly contact the third guide surface 511 without colliding with the first end 520. This reduces the possibility of paper jams, ensuring the stability and accuracy of the paper during the feeding process. It also greatly reduces the shaking and impact of the paper during feeding, thereby improving the image quality of the paper after scanning.

[0071] Reference Figure 1 and Figure 9As shown, in this embodiment, when the cover 200 is flipped open, the paper feeding assembly 1000 leaves the scanning platform 2100, and the first end 520 of the paper guide 500 leaves the contact surface 120 of the paper guide step 100. Since the spring 700 stores a certain downward driving force, the paper guide 500 can move downward relative to the paper output platform 300 under the driving force until the lower side of the end of the paper guide 500 facing the paper output platform 300 abuts against the limiting block 330 of the paper output platform 300, that is, the maximum distance that the paper guide 500 moves downward relative to the paper output platform 300.

[0072] Reference Figure 3 and Figure 10 As shown, in this embodiment, when the cover 200 is placed on the scanning platform 2100, the first end 520 of the paper guide 500 abuts against the contact surface 120 of the paper guide step 100, and the paper guide 500 can move upward a certain distance relative to the paper output platform 300. The spring 700 is compressed by the connecting plate 530 and deformed, so that the spring 700 exerts downward pressure on the paper guide 500, thereby driving the first end 520 to abut tightly against the contact surface 120, so that the first end 520 of the paper guide 500 is lower than the second end 110 of the paper guide step 100.

[0073] Reference Figure 11 As shown, in this embodiment of the invention, the paper guide 500 is rotatably connected to the paper output platform 300, and the driving component 600 is a torsion spring 800. One end of the torsion spring 800 is connected to the paper output platform 300, and the other end is connected to the paper guide 500. Specifically, the side of the paper guide 500 facing the paper output platform 300 is rotatably connected to the side of the paper output platform 300 facing the paper guide 500. One end of the torsion spring 800 is connected to the inner wall of the paper output platform 300, and the other end is connected to the inner wall of the paper guide 500. The torsion spring 800 can drive the paper guide 500 to rotate relative to the paper output platform 300. Based on this, the torsion spring 800 can drive the paper guide 500 to rotate upward or downward relative to the paper output platform 300, thereby controlling the relative position of the paper guide 500 and the paper guide step 100.

[0074] Reference Figure 11 and Figure 12As shown in this embodiment of the invention, the paper guide 500 has rotating shafts 541 at both ends along the width of the cover 200, and the paper output platform 300 has through holes 350 corresponding to the rotating shafts 541. The rotating shafts 541 rotatably pass through the through holes 350. Specifically, the paper guide 500 has connecting blocks 540 protruding from both ends along the width of the cover 200, and rotating shafts 541 protruding from the connecting blocks 540. The paper output platform 300 has through holes 350 corresponding to the rotating shafts 541 at both ends along the width of the cover 200. The rotating shafts 541 can pass through the through holes 350 and rotate within them, allowing the rotating shafts 541 to rotate relative to the paper output platform 300. Based on this, the paper guide 500 can rotate downwards or upwards relative to the paper output platform 300, while also preventing the paper guide 500 from detaching from the paper output platform 300, thus stabilizing the connection between the two.

[0075] Reference Figure 13 and Figure 14 As shown, in this embodiment of the present invention, the paper guide 500 has a first wall surface 550 on the side facing the paper output table 300, and the paper output table 300 has a second wall surface 360 ​​on the side facing the paper guide 500. The first wall surface 550 and the second wall surface 360 ​​are spaced apart. The paper guide 500 has a first state and a second state, as shown in the figure. Figure 13 As shown, when the paper guide 500 is in the first state, that is, when the paper guide 500 rotates downward relative to the paper output table 300, the lower end of the second wall surface 360 ​​abuts against the lower end of the first wall surface 550 to restrict the paper guide 500 from continuing to rotate downward; refer to Figure 14 As shown, when the paper guide 500 is in the second state, that is, the paper guide 500 rotates upward relative to the paper output table 300, the second wall surface 360 ​​abuts against the upper end of the first wall surface 550 to limit the paper guide 500 from continuing to rotate upward. Based on this, this embodiment limits the angle range of the paper guide 500 relative to the paper output table 300, thereby accurately controlling the relative position of the paper guide 500 and the paper guide step 100.

[0076] Reference Figure 11As shown, in one example, two torsion springs 800 are provided and spaced apart along the length of the paper output platform 300. When the paper guide 500 is driven by the drive member 600, the driving stress can be evenly distributed, thereby ensuring the overall movement direction and stability of the paper guide 500. In this embodiment, in order to achieve a downward rotation tendency of the paper guide 500 relative to the paper output platform 300, when assembling the torsion spring 800, one end of the torsion spring 800 is pre-rotated relative to the other end to store the elastic potential energy of the torsion spring 800 rotating downward relative to the paper output platform 300. The elastic potential energy is the driving force, thereby driving the paper guide 500 to rotate downward relative to the paper output platform 300. When the cover 200 is placed on the scanning platform 2100, the first end 520 of the paper guide 500 will tightly abut against the abutment surface 120 of the paper guide step 100, so that the first end 520 of the paper guide 500 is lower than the second end 110 of the paper guide step 100.

[0077] Based on this, the drive unit 600 can accurately control the relative position of the paper guide 500 and the paper guide step 100, ensuring that the paper can smoothly contact the third guide surface 511 without colliding with the first end 520, reducing the possibility of paper jams, thereby ensuring the stability and accuracy of the paper during the paper feeding process, greatly reducing the phenomenon of paper shaking and impact during the paper feeding process, and thus improving the image quality of the paper after scanning.

[0078] Reference Figure 6 , Figure 10 and Figure 14 As shown, in this embodiment of the present invention, the first guide surface 311 and the third guide surface 511 are inclined, and the end of the first guide surface 311 facing the third guide surface 511 is lower than the end of the third guide surface 511 facing the first guide surface 311. Specifically, the upper side of the paper guide 500 is inclined and has a first inclined surface 560. The end of the first inclined surface 560 facing the paper guide step 100 is lower than the end facing the paper output table 300. The paper guide 500 protrudes from the first inclined surface 560 in the direction from the end facing the paper guide step 100 to the end facing the paper output table 300 to form a plurality of first guide ribs 510. The end of the first guide rib 510 facing the paper guide step 100 is the first inclined end 512, and the end facing the paper output table 300 is the second inclined end 513, that is, the second inclined end 513 is higher than the first inclined end 512. The upper end surfaces of the plurality of first guide ribs 510 are combined to form the third guide surface 511.

[0079] Reference Figure 6 , Figure 10 and Figure 14As shown, in this embodiment, the upper side of the paper output table 300 is inclined and has a second inclined surface 370. The end of the second inclined surface 370 facing the paper guide 500 is lower than the end facing the paper guide 500. The paper output table 300 protrudes from the second inclined surface 370 in the direction from the end facing the paper guide 500 to the end facing the paper guide 500 to form a plurality of second guide ribs 310. The end of the second guide rib 310 facing the paper guide 500 is the third inclined end 312, and the end facing the paper guide 500 is the fourth inclined end 313, that is, the fourth inclined end 313 is higher than the third inclined end 312. The upper end surfaces of the plurality of second guide ribs 310 are combined to form a first guide surface 311. The number and position of the first guide ribs 510 correspond to the number and position of the second guide ribs 310.

[0080] Continue to refer to Figure 6 , Figure 10 and Figure 14 As shown, in this embodiment, the side of the paper guide 500 facing the output table 300 connects to the side of the output table 300 facing the paper guide 500. Specifically, the second inclined end 513 connects to the third inclined end 312. When the cover 200 is placed on the scanning platform 2100, the end of the first guide surface 311 facing the third guide surface 511 is lower than the end of the third guide surface 511 facing the first guide surface 311. That is, the third inclined end 312 needs to be lower than the second inclined end 513 so that the third guide surface 511 can smoothly connect to the first guide surface 311. Based on this, the position of the paper guide 500 relative to the output table 300 is reasonably set, avoiding the phenomenon of paper skewing, shaking and impact when passing through the connection between the paper guide 500 and the output table 300, ensuring the smoothness and stability of the paper feeding channel 900, thereby improving the image quality of the paper after scanning and effectively improving the operational stability of the paper feeding assembly 1000.

[0081] Reference Figure 1 , Figure 2 and Figure 3As shown, an embodiment of this utility model also proposes an image forming device 2000, including a scanning platform 2100 and a paper feeding assembly 1000 as described in the above embodiment. The scanning platform 2100 is located below the paper feeding assembly 1000, and a hinged cover 200 is rotatably connected to the scanning platform 2100. The hinged cover 200 can be rotated open relative to the scanning platform 2100. In this embodiment, the image forming device 2000 has two paper feeding methods to achieve paper scanning: one is to open the hinged cover 200 and directly place the paper into the scanning plane area 2300 for scanning; the other is to use a paper feeding device 400 to automatically feed the paper for scanning. In the paper feeding assembly 1000, a paper guide 500 is positioned between the paper guide step 100 and the paper output platform 300 and connected to the paper output platform 300. A paper feeding device 400 is positioned above the cover 200. The third guide surface 511 of the paper guide 500 cooperates with the second guide surface 410 of the paper feeding device 400 to guide the paper away from the scanning area 2200, allowing the paper to smoothly transition between the second guide surface 410 and the first guide surface 311. The second guide surface 410 of the paper feeding device 400 cooperates with the first guide surface 311 of the paper output platform 300 to guide the paper movement, thereby achieving paper output. A drive 600 is connected to the paper guide 500 and can drive the first end 520 of the paper guide 500 to move downwards relative to the paper output platform 300, thus... The first end 520 of the paper guide 500 is always lower than the second end 110 of the paper guide step 100. Based on this, the drive unit 600 can accurately control the relative position of the paper guide 500 and the paper guide step 100, ensuring that the paper can smoothly contact the third guide surface 511 without colliding with the first end 520. This reduces the possibility of paper jams and ensures the stability and accuracy of the paper during the feeding process. It also greatly reduces the shaking and impact of the paper during the feeding process, thereby improving the image quality of the paper after scanning. At the same time, it improves the stability and reliability of the image forming equipment 2000, further extends the service life of the image forming equipment 2000, and provides users with a better user experience.

[0082] Since the image forming equipment 2000 adopts all the technical solutions of the paper feeding assembly 1000 of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0083] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
