Description

Technical Field

[0001] This utility model relates to the field of intelligent office equipment technology, specifically to a paper feeding device with an opening and closing paper feeding channel. Background Technology

[0002] Previously, records were primarily kept on paper. While paper records could be stored for a long time, they also had drawbacks such as being time-consuming, labor-intensive, and inconvenient to retrieve. With the advent of the information age and the further popularization of office automation, electronic records have become increasingly important in records management. It can be said that electronic records have become the main form of records management at present.

[0003] Currently, existing technologies include processing devices that perform page feeding, scanning, and coding along the paper feed path. For example, patent document CN218477317U discloses an encoding and printing device that can accurately and efficiently convert paper documents into electronic archives. However, careful analysis reveals that this device employs a double-layer structure with an arc-shaped turning design for the paper feed path. On one hand, the relatively long paper feed path not only increases the paper transport path but also raises the probability of paper shifting or wrinkling during transport. On the other hand, due to the enclosure and structural constraints, the paper feed path is a closed structure that cannot be fully opened and exposed. When paper jams occur during transport, it can usually only be forcibly pulled out from the corners, which is not only slow but also prone to paper damage, resulting in the loss of the original content on the paper.

[0004] Therefore, it is necessary to provide a new technology with a shorter transmission path and easier handling of paper jams. Utility Model Content This invention addresses the shortcomings and defects of the existing technology by proposing a paper feeding device with an openable and closable paper feeding channel. The device is designed with an inclined and closable paper feeding channel, which aims to achieve direct inclined output of paper from top to bottom through the inclined transmission path, and to fully open and expose the paper feeding channel when paper jams occur through the openable and closable structure. This solves the technical problems of existing equipment being prone to paper jams due to the long length of the paper feeding channel, as well as the difficulty in handling paper jams, the easy damage to paper, and the loss of content.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A paper feeding device with an opening and closing paper feeding channel includes a frame and a movable frame. The frame is equipped with an inclined paper feeding base plate, and the movable frame is equipped with a paper feeding cover plate corresponding to the paper feeding base plate. The lower end of the movable frame is configured to be movably connected to the lower end of the frame via a hinge, and the upper end of the movable frame is configured to be connected to the upper end of the frame via a locking member. The movable frame forms an opening and closing structure on the frame through the hinge and the locking member. The movable frame has a locked state and an unlocked state. In the locked state, an inclined paper feeding channel is formed between the paper feeding cover plate and the paper feeding base plate through a spacer. In the unlocked state, the paper feeding channel can be opened by controlling the rotation of the upper end of the movable frame.

[0006] It also includes a drive assembly, which includes a paper feeding motor, a drive wheel assembly, and a driven wheel assembly. The drive wheel assembly and the driven wheel assembly are respectively mounted on the frame and the movable frame. The paper feeding motor is mounted on the upper part of the frame and is used to drive the drive wheel assembly through a belt and pulleys. Under the driving action of the paper feeding motor, the drive wheel assembly and the driven wheel assembly cooperate to output the paper in the paper feeding channel from top to bottom.

[0007] The number of driving wheel sets and driven wheel sets are both 4-6 sets.

[0008] The minimum length of the paper feed path is 650mm, and the inclination of the paper feed path is 30-60 degrees.

[0009] A limiting component for limiting the rotation angle of the movable frame is provided between the movable frame and the machine frame. The limiting component is located in the lower middle part of one side of the machine frame and includes a limiting rod and a limiting pin. The limiting pin is fixed to the side wall of the machine frame. One end of the limiting rod is hinged to the side wall of the movable frame, and the other end is provided with a limiting groove along the length direction. The limiting pin is located in the limiting groove.

[0010] The rotation angle of the movable frame is 25°-45°.

[0011] There are two sets of locking components, symmetrically arranged on both sides between the frame and the movable frame. Each set of locking components includes an L-shaped structural component mounted on the movable frame by an elastic element and a corresponding locking hole opened on the frame. The L-shaped structural component has a natural state and a controlled state. In the natural state, the locking end of the L-shaped structural component is located in the locking hole, and the movable frame is locked and cannot rotate. In the controlled state, the locking end of the L-shaped structural component is disengaged from the locking hole, and the movable frame can rotate.

[0012] The frame has a right-angled triangular structure, including a base. Two right-angled triangular side plates are symmetrically fixed on the base. The side plates are fixed together by a support rod. The paper feed base plate is fixed between the hypotenuses of the two side plates.

[0013] The movable frame includes two side plates fixed by support columns, and a paper feed cover plate is fixed between the two side plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model adopts a tilted and closable paper feeding channel structure. The tilted feeding path allows the paper to be output directly from top to bottom at a tilted angle, which shortens the paper feeding path and reduces the probability of paper deviation. With the closable structure, even if a paper jam occurs, the paper feeding channel can be quickly opened by rotating the movable frame, and the paper feeding channel and the paper inside can be fully exposed. This facilitates the quick removal of jammed paper and avoids paper damage and loss of original content. It has the advantages of fast processing speed, high efficiency, low difficulty, no paper damage and no content loss.

[0015] 2. This invention achieves paper feeding by separately mounting the driving and driven wheel sets on the frame and the movable frame, respectively. This ensures that only the wheel bodies of the driving and driven wheel sets extend into the paper feeding channel, resulting in a smooth and flat interior. This not only minimizes the risk of paper jams but also significantly reduces paper damage should a jam occur. Furthermore, the separate design of the driving and driven wheel sets facilitates adjustment of the paper's thickness during passage.

[0016] 3. This utility model can set 4-6 sets of driving wheel sets and driven wheel sets on the paper feeding channel with a minimum length of 650mm to realize the corresponding processing function of paper documents. It has the advantages of reducing the size of the equipment, improving the smoothness of paper movement in the paper feeding channel and reducing the probability of paper jams.

[0017] 4. This utility model limits the rotation angle of the movable frame through a limiting component, and has the advantages of simple structure and good stability. Attached Figure Description

[0020] Reference Figures 1-5 This utility model provides a paper feeding device with an openable and closed paper feeding channel, including a frame 1, on which an inclined paper feeding base plate 10 is disposed.

[0021] It also includes a movable frame 2, on which a paper feed cover plate 11 corresponding to the paper feed base plate 10 is mounted. The lower end of the movable frame 2 is configured to be movably connected to the lower end of the frame 1 via a hinge, and the upper end of the movable frame 2 is configured to be connected to the upper end of the frame 1 via a locking member 17. The hinge can be a shoulder screw, and the locking member 17 can be a snap-fit ​​structure. The movable frame 2 can be fixed or rotated. Under the mutual cooperation of the hinge and the locking member 17, an openable paper feed channel 5 is formed between the movable frame 2 and the frame 1.

[0022] Specifically, the movable frame 2 has a locked state and an unlocked state. The locked state and the unlocked state can be switched by controlling the locking element 17 to lock or unlock. In the locked state, the paper feed cover 11 covers the paper feed base plate 10, and the paper feed cover 11 and the paper feed base plate 10 form a paper feed channel 5 with the same inclination as the paper feed base plate 10 through a spacer. In the unlocked state, the paper feed channel 5 can be opened by controlling the upper end of the movable frame 2 to rotate.

[0023] It should be noted that both the paper feed base plate 10 and the paper feed cover plate 11 are rectangular in structure. The spacers can be made of rubber material and can be glued to the four corners of the paper feed base plate 10 or the four corners of the paper feed cover plate 11. On the one hand, they are used to form a paper feed channel 5 with a stable gap between the paper feed cover plate 11 and the paper feed base plate 10. On the other hand, they can form a buffer when the paper feed cover plate 11 is rotated to move closer to the paper feed base plate 10, so as to avoid damage to the paper feed cover plate 11 and the paper feed base plate 10 due to hard contact.

[0024] In this embodiment, the paper feeding channel 5 is essentially composed of two inclined plates. The minimum length of the paper feeding channel 5 is 650mm, which is relatively short and has the advantages of reducing the probability of paper jams and the size of the equipment. The inclination angle of the paper feeding channel 5 can be 30-60 degrees, preferably 45 degrees, which has the advantages of simple structure, smooth paper feeding, and less likelihood of paper jams during paper feeding.

[0025] Reference Figures 1-5 It also includes a drive assembly, which includes a paper feeding motor 6, a drive wheel set 18, and a driven wheel set 19. The number of drive wheel sets 18 and driven wheel sets 19 are both 4-6 sets. The distance between adjacent drive wheel sets 18 should be minimized while still ensuring smooth paper feeding. The drive wheel sets 18 and driven wheel sets 19 are respectively mounted on the frame 1 and the movable frame 2. The paper feeding motor 6 is mounted on the upper part of the frame 1 and located on the back of the paper feeding base plate 10. It is used to drive all drive wheel sets 18 simultaneously through belts and pulleys. Under the driving action of the paper feeding motor 6, the drive wheel sets 18 and driven wheel sets 19 cooperate to make the paper in the paper feeding channel 5 tilt downwards for output.

[0026] Reference Figure 2 , Figure 4 In this utility model, a limiting component 12 for limiting the rotation angle of the movable frame 2 is provided between the movable frame 2 and the frame 1. The limiting component 12 can limit the rotation angle of the movable frame 2 to 25°-45°, preferably to 35°, so that the movable frame 2 can be flipped stably, not easily jammed, not easily shaken, and the movable frame 2 occupies less space after flipping.

[0027] Furthermore, the limiting assembly 12 is located in the lower middle part of one side of the frame 1, including a limiting rod 13 and a limiting pin 14. The limiting pin 14 is fixed to the side wall of the frame 1. One end of the limiting rod 13 is hinged to the side wall of the movable frame 2 and can rotate. The other end is provided with a limiting groove of a certain length along the length direction, and the limiting pin 14 is located in the limiting groove. Assume that the limiting groove includes point A located at the end of the limiting rod 13 and point B located in the middle of the limiting rod 13. When the movable frame 2 is rotated to open the paper feeding channel 5, the limiting pin 14 moves from point B to point A relative to the limiting groove, and reaches the limiting endpoint when it moves to point A, at which point the movable frame 2 can no longer rotate.

[0028] Reference Figure 5 In this invention, there are two sets of locking components 17, symmetrically arranged on both sides between the frame 1 and the movable frame 2. Each set of locking components 17 includes an L-shaped structural component mounted on the movable frame 2 via an elastic element (torsion spring) and a corresponding locking hole on the frame 1. The L-shaped structural component has a natural state and a controlled state. In the natural state, the locking end of the L-shaped structural component is located in the locking hole, and the movable frame 2 is locked and cannot rotate. In the controlled state, the locking end of the L-shaped structural component is disengaged from the locking hole, and the movable frame 2 can rotate. Under the locking action of the two sets of locking components 17, the movable frame 2 can be stably and reliably fixed on the frame 1, ensuring that the paper feeding channel 5 and the distance between the driving wheel group 18 and the driven wheel group 19 remain unchanged, thus achieving smooth paper feeding and avoiding paper jams.

[0029] Reference Figures 1-4In this invention, the frame 1 has a right-angled triangular structure and includes a base. Two right-angled triangular side plates are symmetrically fixed to the base by bolts. The side plates are fixed together by upper and lower support rods, forming a stable and reliable support structure for the frame 1. The paper feed base plate 10 is fixed between the hypotenuses of the two side plates. The movable frame 2 includes two side plates fixed by support columns. The paper feed cover plate 11 is fixed between the two side plates, giving the movable frame 2 a stable and reliable support structure.

[0030] Reference Figure 2 , Figure 4 In this utility model, a positioning guide pin 15 and a positioning guide pin hole 16 are provided between the middle of the movable frame 2 and the middle of the frame 1. The positioning guide pin 15 and the positioning guide pin hole 16 can be respectively set on both sides of the paper feeding base plate 10 and both sides of the paper feeding cover plate 11. The positioning guide pin 15 and the positioning guide pin hole 16 can play a guiding and positioning role and cover the paper feeding cover plate 11 when the paper feeding base plate 10 covers it, so as to ensure that the size of the paper feeding channel 5 will not change.

[0031] In practical applications, this invention can be configured with corresponding paper feeding devices 7, scanning devices 8, coding devices 9, controllers 20, and sensors according to the conversion logic to facilitate intelligent conversion of paper documents to electronic documents. Additionally, a paper feed tray 3 and a paper collection tray 4 can be respectively installed at the upper and lower ends of the paper path 5 via the frame 1 to facilitate the placement of paper documents to be processed and the collection of converted paper documents. The paper feed tray 3 can be detachable, and the paper collection tray 4 can be pull-out, allowing for reduced volume when not in use.

[0032] The conveying principle of this utility model is as follows: Paper documents are fed into the paper feeding channel 5 from the top via the paper feeding device 7. Then, driven by the paper feeding motor 6, the drive wheel set 18, and the driven wheel set 19, the paper moves downward along the inclined paper feeding channel 5. During the paper movement, the controller 20, in cooperation with the sensor, scanning device 8, and coding device 9, codes and scans the pages with content on the paper to convert them into electronic documents. When a paper jam occurs, the movable frame 2 is switched to the unlocked state, and the paper feeding channel 5 can be opened by rotating the movable frame 2. Since the paper feeding channel 5 is fully opened, the paper feeding channel 5 and the jammed paper are fully exposed, and the paper can be easily removed for processing, quickly clearing the paper jam without damaging the paper or causing loss of content, thus achieving better results.

[0033] The above description is only a specific embodiment of this utility model. Any feature disclosed in this specification may be replaced by other equivalent features unless otherwise specified. All features or steps in all methods or processes disclosed may be combined in any way except for mutually exclusive features and / or steps.
