[0046] 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.

[0047] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, inside, outside, 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.

[0048] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0049] 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.

[0050] 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.

[0051] Therefore, some embodiments of this utility model propose a paper feeding assembly 1000, suitable for image forming equipment 2000, wherein, with reference to Figure 1As 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.

[0052] Reference Figure 1 , Figure 2 and Figure 7 As shown in this embodiment of the utility model, the paper feeding assembly 1000 includes a cover 200, a paper feeding device 400, a paper guide 500, and a driving component 600. The cover 200 is located on the upper side of the scanning platform 2100, and one side of the cover 200 is rotatably connected to one side of the scanning platform 2100. The 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. 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. 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. A paper output platform 300 is provided on the upper surface of the flip cover 200. The paper output platform 300 is located on the side of the paper guide step 100 facing away from the scanning area 2200 and is fixedly connected to the flip cover 200. In this embodiment, the flip cover 200 and the paper output platform 300 can be integrally formed, or they can be connected by fasteners or other connection methods. This embodiment does not limit this. (Refer to...) Figure 14 As shown, in one example, the flip cover 200 and the paper output table 300 are integrally formed.

[0053] Reference Figure 2 , Figure 3 and Figure 6 As shown, the paper feeding device 400 is disposed on the upper side of the flip cover 200 and is fixedly connected to the flip cover 200. Specifically, the paper feeding device 400 covers the upper side of the left side portion of the flip cover 200. In this embodiment, the paper feeding device 400 can be fixedly connected to the flip cover 200 by fasteners, or it can be connected by other connection methods such as welding. This embodiment does not limit this. In this embodiment, a second guide surface 410 is provided on the lower side of the paper feeding device 400.

[0054] Reference Figure 3 and Figure 6As shown, the paper guide 500 is disposed between the paper guide step 100 and the paper output platform 300, and is located below the paper feeding device 400. The paper guide 500 is connected to the paper feeding device 400. 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 paper output platform 300. 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 both. In this embodiment, the relative position of the paper guide 500 and the paper feeding device 400 can be changed. Specifically, they can be connected movably using fasteners, elastically using elastic elements, or through other connection methods.

[0055] Reference Figure 6 As shown, in this embodiment, the upper side of the paper guide 500 is provided with a third guide surface 510 opposite to the second guide surface 410. The third guide surface 510 and the second guide surface 410 cooperate to guide the paper away from the scanning area 2200. The upper side of the paper output platform 300 is provided with a first guide surface 310 opposite to the second guide surface 410. The first guide surface 310 and the second guide surface 410 cooperate to guide the paper to move away from the paper feeding assembly 1000, thereby realizing paper output. It can be understood that the side of the third guide surface 510 facing the paper output connects to the side of the first guide surface 310 facing the paper guide 500, so that the third guide surface 510 and the first guide surface 310 can cooperate to form a guide surface that is completely corresponding to the second guide surface 410. The second guide surface 410 is spaced apart from the third guide surface 510 and the first guide surface 310, and surrounds to form a paper feeding channel 900, which can guide the paper to move.

[0056] In one example, when the cover 200 is placed on the scanning platform 2100, the paper feeder 400 feeds the paper to the scanning area 2200. After the paper is scanned, it contacts the third guide surface 510 and enters the paper feed channel 900 under its guidance. It leaves the scanning area 2200 along the third guide surface 510 and then leaves the paper feed assembly 1000 along the first guide surface 310.

[0057] Reference Figure 4 , Figure 5 and Figure 7 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. In this embodiment, the driving component 600 can be an elastic component, a motor, a cylinder, or other components with a driving function.

[0058] Reference Figure 6As 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. When the cover 200 is placed on the scanning platform 2100, the drive member 600 can drive the first end 520 to move downward relative to the paper feeding device 400, so that the first end 520 is lower than the second end 110.

[0059] For example, the right side of the second end 110 has an abutment surface 120, which is lower than the second end 110. The right side of the second end 110 is connected to the paper guide 500. When the cover 200 is placed on the scanning platform 2100, the first end 520 of the paper guide 500 moves downward under the drive of the drive member 600, and can directly abut 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 allows the paper to directly contact the third guide surface 510 instead of the first end 520 after passing through the paper guide step 100. 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 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.

[0060] It is understood that, in this embodiment of the present invention, the paper feeding assembly 1000, by placing the paper guide 500 between the paper guide step 100 and the paper output platform 300, and located below the paper feeding device 400, connects the paper guide 500 to the paper feeding device 400. The third guide surface 510 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 310. The second guide surface 410 of the paper feeding device 400 cooperates with the first guide surface 310 of the paper output platform 300 to guide the paper movement, thereby realizing paper output. The driving member 600 is connected to the paper guide 500 and can drive the paper guide 500. The first end 520 of the paper guide 500 moves downward relative to the paper feeding device 400. When the cover 200 is placed on the scanning platform 2100, 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 510 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.

[0061] Reference Figure 5 and Figure 7 As shown, in this embodiment of the present invention, the driving member 600 is an elastic member, and the driving member 600 is disposed between the paper guide member 500 and the paper feeding device 400. Specifically, the paper guide member 500 and the paper feeding device 400 are arranged vertically at a distance, the upper side of the paper guide member 500 is movably connected to the lower side of the paper feeding device 400, the driving member 600 is connected between the paper guide member 500 and the paper feeding device 400, one end of the driving member 600 is connected to the paper guide member 500, and the other end is connected to the paper feeding device 400. The driving member 600 can drive the paper guide member 500 to move downward relative to the paper feeding device 400.

[0062] It is understood that in this embodiment, when the cover 200 is placed on the scanning platform 2100, 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 feeding device 400, ensuring that the paper can pass smoothly 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.

[0063] Reference Figure 7 and Figure 11 As shown in this embodiment of the invention, the side wall of the paper guide 500 is provided with a connecting plate 530. Specifically, the connecting plate 530 protrudes from the side of the paper guide 500 facing the paper feeding device 400. A relief groove 420 corresponding to the connecting plate 530 is formed on the lower side of the paper feeding device 400. The opening of the relief groove 420 faces downward, and the connecting plate 530 is movably inserted into the relief groove 420. In this embodiment, the driving member 600 is disposed between the connecting plate 530 and the bottom wall of the relief groove 420. Specifically, both ends of the driving member 600 are respectively connected to the bottom wall of the connecting plate 530 and the relief groove 420. The driving member 600 can drive the connecting plate 530 to move along the relief groove 420. It can be understood that the driving member 600 can drive the connecting plate 530 to move downward relative to the bottom wall of the relief groove 420, thereby realizing the downward movement of the paper guide 500 relative to the paper feeding device 400.

[0064] Reference Figure 5 , Figure 9 and Figure 11 As shown in this embodiment of the utility model, the end face of the connecting plate 530 facing the inner wall of the relief groove 420 is spaced apart from the inner wall of the relief groove 420. It can be understood that there is a gap between the end face of the connecting plate 530 facing the inner wall of the relief groove 420 and the inner wall of the relief groove 420, and the connecting plate 530 is movably inserted into the relief groove 420.

[0065] Reference Figure 5 and Figure 11As shown, in this embodiment, the end face of the connecting plate 530 facing the inner wall of the clearance groove 420 is provided with a plurality of guide ribs 532 spaced apart. The guide ribs 532 protrude from the connecting plate 530 and extend along the line connecting the scanning platform 2100 and the paper feeding device 400. Specifically, the plurality of guide ribs 532 are circumferentially spaced around the end face of the connecting plate 530 facing the inner wall of the clearance groove 420 and extend in the vertical direction. In this embodiment, the number of guide ribs 532 can be 3, 6, 8, etc., and this embodiment does not limit this. In one example, there are 5 guide ribs 532. When the connecting plate 530 passes through the relief groove 420, the guide rib 532 can abut against the inner wall of the relief groove 420, thereby accurately guiding the connecting plate 530 to move along the relief groove 420. At the same time, it reduces the contact area between the connecting plate 530 and the relief groove 420, thereby reducing the friction between the connecting plate 530 and the relief groove 420, thus improving the smoothness of the connecting plate 530 moving along the relief groove 420, reducing the possibility of jamming when the paper guide 500 moves relative to the paper feeding device 400, thereby improving the smoothness and efficiency of the paper guide 500 moving relative to the paper feeding device 400.

[0066] Reference Figure 5 , Figure 8 and Figure 11 As shown, in this embodiment of the present invention, the connecting plate 530 is provided with a guide hole 533. Specifically, the guide hole 533 is located on the lower side of the connecting plate 530 and extends through the connecting plate 530 in the vertical direction. In this embodiment, the shape of the guide hole 533 can be square, circular, or other shapes, and this embodiment does not limit this. In one example, the guide hole 533 is an oblong hole. In this embodiment, a guide post 430 is formed by protruding from the bottom wall of the clearance groove 420. The guide post 430 extends along the direction of the paper feeding device 400 toward the scanning platform 2100. Specifically, the guide post 430 corresponding to the guide hole 533 is formed by protruding downward from the bottom wall of the clearance groove 420. The guide post 430 is cylindrical and can be movably inserted through the guide hole 533, thereby restricting the movement direction of the guide post 430 and thus accurately controlling the movement trajectory of the paper guide 500.

[0067] Reference Figure 5 , Figure 7 and Figure 9As shown, in this embodiment of the invention, a limiting member 800 is provided at the lower end of the guide post 430. The limiting member 800 is detachably connected to the lower end of the guide post 430, thereby facilitating the assembly and disassembly of the paper guide 500, the driving member 600, and the paper feeding device 400. In this embodiment, when the connecting plate 530 moves downward relative to the clearance groove 420 to the lower end of the guide post 430, the limiting member 800 can abut against the lower side of the connecting plate 530, thereby restricting the connecting plate 530 from disengaging from the clearance groove 420. This can be understood as limiting the maximum downward movement of the paper guide 500 relative to the paper feeding device 400, thereby ensuring the relative position and structural stability of the paper guide 500 and the paper feeding device 400, and reducing the possibility of the paper guide 500 dislodging. In this embodiment, the limiting member 800 can be a screw, rivet, etc., and this embodiment is not limited to this. In one example, the limiting member 800 is a bolt.

[0068] Reference Figure 5 and Figure 7 As shown, in this embodiment of the invention, the driving component 600 is a spring 700, which is sleeved on the guide post 430. One end of the spring 700 abuts against the connecting plate 530, and the other end abuts against the bottom wall of the clearance groove 420. It is understood that the spring 700 has good elasticity and stable stiffness. When subjected to external force, it deforms and returns to its original shape after the external force is removed, thus achieving the functions of buffering, vibration reduction, and energy storage. When the connecting plate 530 moves up and down relative to the clearance groove 420, the guide post 430 can guide the spring 700 to compress upwards or extend downwards, thereby ensuring the stability of the spring 700's operation. In this embodiment, the two ends of the spring 700 are respectively connected to the paper guide 500 and the paper feeding device 400. 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 feeding device 400. That is, the first end 520 of the paper guide 500 moves downward relative to the paper feeding device 400. When the cover 200 is placed on the scanning platform 2100, the first end 520 abuts against the abutting surface 120 of the paper guide step 100, thereby making the first end 520 lower than the second end 110.

[0069] During assembly, the spring 700 is first sleeved on the guide post 430, and then the connecting plate 530 is inserted into the clearance groove 420. The connecting plate 530 compresses the spring 700 upward, so that the guide post 430 passes through the guide hole 533. Then, the limiting member 800 is installed at the lower end of the guide post 430. The limiting member 800 can abut against the lower side of the connecting plate 530, thereby completing the connection and installation between the paper guide 500, the driving member 600 and the paper feeding device 400.

[0070] Reference Figure 5As shown, in this embodiment of the present invention, the connecting plate 530 is provided with a perimeter 531, which is connected to the periphery of the connecting plate 530 and extends along the scanning platform 2100 toward the paper feeding device 400, thereby forming a first groove 534 with the connecting plate 530. Specifically, the perimeter 531 is located on the upper side of the connecting plate 530, and the outline of the perimeter 531 projected in the vertical direction matches the periphery outline of the connecting plate 530. In this embodiment, the connection between the perimeter 531 and the connecting plate 530 can be welding or other connection methods such as fasteners; this embodiment does not limit this. In one example, the perimeter 531 and the connecting plate 530 are integrally formed.

[0071] Reference Figure 5 and Figure 11 As shown, in this embodiment, the connection between the perimeter 531 and the connecting plate 530 can form a first groove 534. The opening of the first groove 534 faces upward, and the spring 700 passes through the first groove 534. It can be understood that one end of the spring 700 is connected to the bottom wall of the first groove 534, and the other end is connected to the bottom wall of the relief groove 420. When the connecting plate 530 moves up and down relative to the relief groove 420, the spring 700 will deform. The inner wall of the first groove 534 can limit the irregular deformation of the spring 700 and maintain the normal compression or elongation deformation of the spring 700, thereby ensuring the normal operation of the spring 700 and thus ensuring the stability of the relative movement of the paper guide 500 and the paper feeding device 400.

[0072] Reference Figure 4 , Figure 7 and Figure 9 As shown in this embodiment of the invention, the paper guide 500 has connecting plates 530 at both ends along the width of the cover 200. The paper feeding device 400 has two clearance grooves 420 corresponding to the two connecting plates 530. Two driving members 600 are respectively installed on the connecting plates 530 at both ends of the paper guide 500, and the two connecting plates 530 pass through the two clearance grooves 420. When the paper guide 500 moves under the action of the driving members 600, the two connecting plates 530 can evenly distribute the driving stress, thereby ensuring the overall movement direction and stability of the paper guide 500. Correspondingly, two limiting members 800 are provided and are respectively installed on the lower ends of the two guide posts 430. When the lower side of the connecting plate 530 abuts against the limiting member 800, it can stably restrict the paper guide 500, thereby preventing the paper guide 500 from detaching from the paper feeding device 400.

[0073] In order to achieve a downward tendency for the paper guide 500 to move relative to the paper feeder 400, the spring 700 needs to be compressed upward in advance when assembling the spring 700, thereby generating downward elastic potential energy. The elastic potential energy is the driving force, thereby storing the driving force for the paper guide 500 to move downward relative to the paper feeder 400.

[0074] Reference Figure 1 and Figure 12 As 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 table 300 under the driving force until the lower side of the connecting plate 530 abuts against the limiting member 800, that is, the maximum distance that the paper guide 500 moves downward relative to the paper feeding device 400.

[0075] Reference Figure 2 and Figure 13 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. The paper guide 500 can move upwards relative to the paper feeding device 400. The spring 700 is compressed by the connecting plate 530, causing deformation and downward pressure on the paper guide 500. This forces the first end 520 to abut tightly against the contact surface 120, making the first end 520 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 510 without colliding with the first end 520, thus reducing the possibility of paper jams.

[0076] Reference Figure 5 , Figure 7 and Figure 10 As shown in this embodiment of the invention, the paper output platform 300 has a limiting part 320 on the side facing the paper guide 500. Specifically, the lower end of the paper output platform 300 protrudes to the left to form the limiting part 320, which corresponds to the position on the lower side of the clearance groove 420. After the paper guide 500, the driving member 600, and the paper feeding device 400 are assembled, the limiting part 320 covers the opening of the clearance groove 420 to prevent the connecting plate 530 from disengaging from the clearance groove 420. In this embodiment, the paper output platform 300 has two limiting parts 320 corresponding to the two clearance grooves 420 in the width direction of the cover 200.

[0077] In this embodiment, the connecting plate 530 passes through the clearance groove 420, and the limiting part 320 covers the opening of the clearance groove 420. Therefore, the connecting plate 530 is located between the clearance groove 420 and the limiting part 320. When the limiting member 800 becomes loose or damaged, the connecting plate 530 will fall downwards, and its lower side will abut against the limiting part 320, thereby further restricting the connecting plate 530 from disengaging from the clearance groove 420. It can be understood that the limiting part 320 is a second layer of restrictive structure that prevents the connecting plate 530 from disengaging from the clearance groove 420, thereby further increasing the structural stability of the paper feeding assembly 1000.

[0078] Reference Figure 1 and Figure 2 As 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 into the scanning area 2200 for scanning.

[0079] In this embodiment, in the paper feeding assembly 1000, the paper guide 500 is disposed between the paper guide step 100 and the paper output platform 300, and located below the paper feeding device 400. The paper guide 500 is connected to the paper feeding device 400. The third guide surface 510 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 310. The second guide surface 410 of the paper feeding device 400 cooperates with the first guide surface 310 of the paper output platform 300 to guide the paper movement, thereby realizing paper output. The driving member 600 is connected to the paper guide 500 and can drive the first end 520 of the paper guide 500 to face downward relative to the paper feeding device 400. The movement ensures 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 510 without colliding with the first end 520. This reduces the possibility of paper jams, thereby ensuring 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, thus 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 extending the service life of the image forming equipment 2000 and providing users with a better user experience.
