Description

Technical Field

[0001] This utility model relates to the field of hardcover bookbinding technology, and in particular to a flipping device and a paper-adding device. Background Technology

[0002] In the binding process of hardcover books, adhesives are sometimes required, such as when a hard cover needs to be glued to the book block. In practice, the adhesives used typically have a certain moisture content. During the process of the adhesive forming effective bonding strength, the moisture in the adhesive can seep into the inner pages of the book, causing the pages to wrinkle due to dampness and affecting product quality. To address this, existing processing methods involve adding a spacer between the cover or back cover and the inner pages after the adhesive has been applied and before the moisture seeps into the pages. This spacer absorbs moisture and reduces the amount of water that penetrates into the inner pages.

[0003] Currently, there is an automatic separator paper adding device. When the book is laid flat, the device can add separator paper between one of the cover or back cover and the inner pages. However, for the other cover, the book needs to be flipped over before the separator paper can be added. Existing solutions address this by manually flipping the book, but this is inefficient and costly. Another method is to use a conveyor to create a height difference, allowing the book to flip under gravity. However, because the separator paper needs to be added before the adhesive has cured, there is no effective connection between the hard cover and the book block. This height difference method can easily cause the unfixed cover to shift or detach, potentially damaging the book.

[0050] The embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0051] Figure 1 The structure of the flipping device 100 according to some embodiments of the present invention is shown. In this embodiment, the flipping device 100 is used to flip the book 200 (see [link]). Figure 4 To flip the book, for example, flip book 200 from the first position to the second position. The following section combines... Figure 1 The flipping device 100 will be described.

[0052] like Figure 1 As shown, the flipping device 100 includes a feed end 110, a first conveying mechanism 120, at least one set of clamps 130 and a rotating shaft 140.

[0053] The feed end 110 can be connected to the front device of the flipping device 100. For example, the flipping device 100 is used in the paper-adding device. The specific cooperation with the paper-adding device will be described in subsequent embodiments.

[0054] In this embodiment, the book 200 enters the flipping device 100 from the feed end 110 in a first posture. Preferably, the feed end 110 has a flat surface, and the first posture of the book 200 is that it is laid flat on the flat surface with either the cover or the back cover of the book 200 facing upwards. In some embodiments, the feed end 110 may not provide an independent power source. For example, the book 200 may enter the flipping device 100 under the drive of a front-end device, or it may cooperate with the first conveying mechanism 120, which drives the book 200 into the flipping device 100.

[0055] The first conveying mechanism 120 is located downstream of the feed end 110 and can drive the book 200 to move. The first conveying mechanism 120 includes, for example, a conveyor belt, a conveyor roller, etc. After the book 200 enters the flipping device 100 from the feed end 110, it moves along the first conveying mechanism 120 in a first posture.

[0056] In this embodiment, the flipping device 100 includes at least one set of clamps 130. The clamps 130 are disposed downstream of the first conveying mechanism 120, or the clamps 130 partially overlap with the first conveying mechanism 120. When the book 200 moves along the first conveying mechanism 120, the book 200 moves into the clamps 130 so that the clamps 130 can hold the book 200.

[0057] In some embodiments, the clamp 130 can apply opposing clamping forces to the book 200 to keep the book 200 fixed relative to the clamp 130. In other embodiments, the clamp 130 can only hold the posture of the book 200 (relative to the approximate posture of the clamp 130) without clamping the book 200, ensuring that the book 200 will not fall or flip inside the clamp 130 during the flipping process. For clamps 130 that do not require clamping the book 200, there is no need to provide a power source for the clamp 130, which simplifies the power system of the flipping device 100. Preferably, the clamp 130 internally defines the movement space of the book 200, for example, the movement space defined by the clamp 130 is slightly larger than the thickness of the book 200. The structure of the clamp 130 will be described in detail in subsequent embodiments with reference to the accompanying drawings. Preferably, the inner surface of the clamp 130 can also be provided with a flexible cushioning structure to reduce the risk of the clamp 130 bumping or scratching the book 200.

[0058] In some embodiments, the flipping device 100 includes multiple sets of clamps 130. Each set of clamps 130 can be used individually to hold the book 200. The structures of each set of clamps 130 may be the same or different.

[0059] The relative positions of multiple clamps 130 can be kept fixed, for example, by integral molding or by welding, gluing, riveting, or bolting. The clamps 130 can rotate around the pivot 140 to cause the book 200 inside the clamps 130 to flip, and within a preset stroke, the book 200 flips to a second position. Figure 1 As shown, in some embodiments, the axial direction of the rotating shaft 140 is perpendicular to the movement direction of the first conveying mechanism 120. The first conveying mechanism 120 moves the book 200 into the clamp 130 in a first posture. The clamp 130 can maintain the posture of the book 200 to a certain extent. For example, the clamp 130 may clamp the book 200 tightly or limit the range of motion of the book 200 within the clamp 130, so that when the clamp 130 moves the book 200 around the rotating shaft 140, the posture of the book 200 relative to the clamp 130 remains approximately stable. After the clamp 130 can rotate around the rotating shaft 140 by a preset stroke, the book 200 can be converted to a second posture.

[0060] In this embodiment, the cover orientation of the book 200 in the first posture is different from the cover orientation of the book 200 in the second posture. Preferably, the cover orientation of the book 200 in the first posture is opposite to the cover orientation of the book 200 in the second posture. For example, the cover of the book 200 faces upward in the first posture, and faces downward in the second posture. In other words, the book 200 is rotated 180° by the clamp 130.

[0061] In some embodiments, the cover orientation of the book 200 in the first and second postures may not be completely opposite. For example, the first and second postures of the book 200 may have a certain tilt angle relative to the horizontal face to facilitate cooperation with the paper insertion mechanism, such as to facilitate the paper insertion mechanism to open the cover or back cover.

[0062] In this embodiment, the book 200 is rotated by the clamp 130 and the rotating shaft 140, which enables automated control, reduces manual labor intensity and costs, and prevents the book 200 from falling or colliding due to height differences, thus ensuring the structural stability of the book 200 and reducing the probability of damage. Furthermore, the clamp 130 can maintain or hold the posture of the book 200, and after the clamp 130 rotates a certain angle, the book 200 can be accurately flipped to a second posture, facilitating subsequent processing of the book 200.

[0063] like Figure 1As shown, according to a preferred embodiment of the present invention, the flipping device 100 includes multiple sets of clamps 130. All sets of clamps 130 are arranged circumferentially around the rotating shaft 140 and can all rotate around the rotating shaft 140. Preferably, the multiple sets of clamps 130 can be evenly arranged circumferentially around the rotating shaft 140. When the multiple sets of clamps 130 rotate around the rotating shaft 140, the book 200 can continuously move along the first conveying mechanism 120 into one set of clamps 130, which helps to improve work efficiency.

[0064] like Figure 2 As shown, in a preferred embodiment of this utility model, the clamp 130 and the first conveying mechanism 120 partially overlap. The first conveying mechanism 120 includes multiple parallel and spaced-apart first conveyor belts 121, and the clamp 130 includes multiple parallel and spaced-apart toothed structures 131. Furthermore, the positions of the multiple toothed structures 131 correspond to the gaps between the multiple first conveyor belts 121. When the clamp 130 rotates around the pivot 140, the toothed structures 131 can pass through the gaps between the multiple first conveyor belts 121, preventing interference between the clamp 130 and the first conveying mechanism 120 during rotation around the pivot 140.

[0065] Specifically, such as Figure 2 As shown, the first conveying mechanism 120 includes five parallel first conveyor belts 121, with gaps between adjacent first conveyor belts 121. The clamp 130 includes four toothed structures 131, which are parallel to the first conveyor belts 121, and the positions of the toothed structures 131 correspond to the gaps between the first conveyor belts 121. For example, the width of the gap between the first conveyor belts 121 is slightly larger than the width of one toothed structure 131, so that the toothed structure 131 can pass through the gap between the first conveyor belts 121.

[0066] In this embodiment, multiple first conveyor belts 121 can operate synchronously, with the book 200 resting on them. After the book 200 is moved into the clamp 130, it rests on multiple toothed structures 131. By controlling the clamp 130 to rotate around the pivot 140, the book 200 can be disengaged from the first conveyor belts 121 and flipped with the clamp 130.

[0067] According to a preferred embodiment of the present invention, such as Figure 3As shown, the clamp 130 includes a first gripper 132 and a second gripper 133. The first gripper 132 and the second gripper 133 are arranged opposite to each other, and the book 200 moves along the first conveying mechanism 120 between the first gripper 132 and the second gripper 133. For example, in some embodiments, the first gripper 132 and the second gripper 133 are parallel to each other and are bent at one end near the pivot 140 to connect with each other, or both the first gripper 132 and the second gripper 133 are connected to the pivot 140, and the view along the axial direction of the pivot 140 is generally U-shaped.

[0068] In a preferred embodiment of this utility model, such as Figure 3 As shown, the first gripper 132 and the second gripper 133 are both composed of toothed structures 131, and the toothed structures 131 in the first gripper 132 and the second gripper 133 are aligned and located at the gap position of the multiple first conveyor belts 121.

[0069] In some embodiments, the flipping device 100 includes multiple sets of clamps 130, each set of clamps 130 including a first gripper 132 and a second gripper 133. The first gripper 132 and the second gripper 133 in different sets of clamps 130 may have the same structure, or they may have different dimensions along the length of the toothed structure 131, or the distance between the first gripper 132 and the second gripper 133 may be unequal, so that different sets of clamps 130 can match books 200 of different sizes, thereby improving the applicability of the flipping device 100. Alternatively, in some embodiments, the clamps 130 are detachable from the pivot 140, allowing for the replacement of size-matching clamps 130 when flipping books 200 of different sizes.

[0070] like Figure 4 As shown, according to a preferred embodiment of the present invention, when the clamp 130 is in its initial position, the first gripper 132 is located above the first conveying mechanism 120, and the second gripper 133 is located below the first conveying mechanism 120, or flush with the first conveying mechanism 120. For example, the surface of the second gripper 133 opposite to the first gripper 132 is lower than the upper surface of the first conveyor belt 121, or flush with the upper surface of the first conveyor belt 121.

[0071] Initially, the clamp 130 remains fixed. The first conveying mechanism 120 is activated, moving the book 200 into the clamp 130, for example, between the first gripper 132 and the second gripper 133. The distance between the first gripper 132 and the second gripper 133 is set to be slightly greater than the thickness of the book 200 when laid flat. Preferably, the second gripper 133 is positioned slightly below the upper surface of the first conveying mechanism 120, and the distance between the first gripper 132 and the upper surface of the first conveying mechanism 120 is slightly greater than the thickness of the book 200 when laid flat, to prevent the book 200 from rubbing against the first gripper 132 and the second gripper 133 when entering the clamp 130, thus affecting the product quality of the book 200.

[0072] According to a preferred embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the flipping device 100 also includes a second conveying mechanism 150. The second conveying mechanism 150 is disposed on the side of at least one set of clamps 130 away from the first conveying mechanism 120, for example, in... Figure 1 and Figure 2 In the middle, the first conveying mechanism 120 is located on the left side of the clamp 130, and the second conveying mechanism 150 is located on the right side of the clamp 130.

[0073] In some embodiments, the second conveying mechanism 150 and at least one set of clamps 130 are adjacent to or partially overlap each other. In this embodiment, the positional relationship between the second conveying mechanism 150 and the clamps 130 indicates the positional relationship of the clamps 130 after rotating about the pivot 140 to be close to the second conveying mechanism 150. For example, in some embodiments, the flipping device 100 includes a set of clamps 130, which, when the clamps 130 are close to the first conveying mechanism 120, such as in the initial position, are adjacent to or partially overlap with the first conveying mechanism 120. When the clamps 130 rotate about the pivot 140 to be close to the second conveying mechanism 150, the clamps 130 are adjacent to or partially overlap with the second conveying mechanism 150.

[0074] In other embodiments, the clamp 130 may also be configured not to remain in the initial position, but to continuously rotate around the axis 140 to improve work efficiency. For example, by adjusting the speed at which the clamp 130 rotates around the axis 140 and the speed of the first conveying mechanism 120, the clamp 130 can pick up the book 200 without stopping and continue rotating to improve work efficiency.

[0075] like Figure 1As shown, the rotating shaft 140 is located between the first conveying mechanism 120 and the second conveying mechanism 150. When the clamp 130 drives the book 200 to rotate around the rotating shaft 140 to the second posture, the clamp 130 and the book 200 are positioned close to the second conveying mechanism 150, or partially overlap with the second conveying mechanism 150, so that the book 200 moves along the second conveying mechanism 150 in the second posture. For example, the book 200, in the second posture, passes through the second conveying mechanism 150 to detach from the flipping device 100 and enters the next process.

[0076] According to a preferred embodiment of the present invention, such as Figure 1 As shown, the second conveying mechanism 150 partially overlaps with the clamp 130. The second conveying mechanism 150 includes multiple parallel and spaced second conveyor belts 151, and the positions of the second conveyor belts 151 correspond to the gaps between the multiple toothed structures 131 to avoid interference between the clamp 130 and the second conveying mechanism 150 during rotation around the axis 140. In this embodiment, the toothed structures 131 in the clamp 130 can pass through the gaps between the second conveyor belts 151, allowing the book 200 to be placed on the second conveyor belts 151 in a second posture. Simultaneously, it enables continuous unidirectional rotation of the clamp 130 around the axis 140, which improves work efficiency and reduces control difficulty.

[0077] Furthermore, in a preferred embodiment of this utility model, the flipping device 100 includes multiple sets of clamps 130. The multiple sets of clamps 130 can be evenly arranged on the rotating shaft 140. Driving the multiple sets of clamps 130 to rotate around the rotating shaft, in conjunction with the speed of the first conveying mechanism 120 and the feeding speed of the book 200, can enable the multiple sets of clamps 130 to continuously drive the book 200 to flip without stopping, thereby improving work efficiency.

[0078] According to a preferred embodiment of the present invention, the first conveying mechanism 120 and the second conveying mechanism 150 are located in the same horizontal plane. The book 200 is initially placed horizontally with the cover facing up (or down), and moves along the first conveying mechanism 120 into the clamp 130. The clamp 130 then rotates the book 200 180° to a second position, where it is again placed horizontally with the cover facing down (or up), and moves along the second conveying mechanism 150 to the next workstation. The flipping device 100 in this embodiment has a simple structure, is easy to control, occupies little space, and ensures that the book 200 maintains a stable posture during its movement along the first conveying mechanism 120 and the second conveying mechanism 150, thus reducing malfunctions or downtime.

[0079] like Figure 5 As shown, according to a preferred embodiment of the present invention, the flipping device 100 further includes a drive module 160, a sensor 170, and a control module 180.

[0080] The drive module 160 is connected to the clamp 130 and can drive the clamp 130 to rotate around the shaft 140. For example, the drive module 160 includes a motor, the output shaft of which coincides with the axial direction of the shaft 140 and is connected to the clamp 130 which is arranged circumferentially around the shaft 140. Driven by the motor, the clamp 130 rotates around the shaft 140.

[0081] Sensor 170 can acquire the position of book 200 on the first conveying mechanism 120. For example, sensor 170 includes a vision sensor, a gravity (pressure) sensor, a through-beam sensor, etc., which can detect whether book 200 is on the first conveying mechanism 120 and the position to which book 200 moves along the first conveying mechanism 120.

[0082] The control module 180 is signal-connected to the drive module 160 and the sensor 170. The sensor 170 can acquire the position information of the book 200 on the first conveying mechanism 120, and the control module 180 can be controlled to drive or brake based on this position information. For example, the control module 180 can be configured to start the drive module 160 when the book 200 has completely moved into the clamp 130 along the first conveying mechanism 120, reducing the risk that the clamp 130 may fail to hold the book 200 during rotation, causing the book 200 to fall out. When the sensor 170 detects that there is no book 200 on the first conveying mechanism 120, the control module 180 can control the drive module 160 to brake, avoiding energy waste. Preferably, when the control module 180 controls the drive module 160 to brake, it can control the drive module 160 to drive the clamp 130 to the initial position in the aforementioned embodiment, and then control the motor to stop.

[0083] Furthermore, the control module 180 can also control the speed at which the drive module 160 drives the fixture 130 to rotate around the shaft 140, so that the rotation speed of the fixture 130 matches the speed of the first conveying mechanism 120 and the second conveying mechanism 150.

[0084] According to a preferred embodiment of the present invention, the rotating shaft 140 can move in a direction perpendicular to the first conveying mechanism 120. For example, if the first conveying mechanism 120 is arranged horizontally, the rotating shaft 140 can move vertically to drive the clamp 130 to move relative to the first conveying mechanism 120 and move it out of the range of the first conveying mechanism 120. For example, the clamp 130 can be moved vertically by rotating 140 so that the position of the second gripper 133 in the clamp 130 is flush with the upper surface of the first conveyor belt 121. Alternatively, for example, in some scenarios where it is not necessary to flip the book 200, the rotating shaft 140 can drive the clamp 130 away from the first conveying mechanism 120, so that the first conveying mechanism 120 can be used as a conventional conveyor belt without the need for an additional conveyor belt, thus enriching the application scenarios of the flipping device 100.

[0085] like Figure 6 As shown, an embodiment of this utility model also includes a paper separator adding device 10, which is used to add paper separators between the cover and inner pages of the book 200, and between the back cover and inner pages. The following describes the process in conjunction with... Figure 6 The paper adding device 10 will be described.

[0086] like Figure 6 As shown, the paper-adding device 10 in this embodiment includes a feeding conveyor belt 11, a first paper-inserting mechanism 12, a flipping device 100, and a second paper-inserting mechanism 13. The flipping device 100 can be the flipping device 100 described in the previous embodiments, and the specific structure of the flipping device 100 will not be described again.

[0087] In this process, the book 200 moves along the feeding conveyor belt 11. For example, after completing the previous process, the book 200 enters the process of adding spacers. Specifically, the previous process may be gluing a hard cover onto the book block, and the equipment used in the previous process may be, for example, a hardcover binding machine. After the hard cover is glued to the surface of the book block, the adhesive has not yet cured, and moisture has not yet seeped into the inner pages of the book block. The spacer adding device 10 adds spacers between the cover and the inner pages, and between the back cover and the inner pages, to absorb the moisture in the adhesive and reduce the risk of the inner pages of the book 200 wrinkling due to water absorption.

[0088] The first paper insertion mechanism 12 is located downstream of the feeding conveyor belt 11 or in the direction of movement of the feeding conveyor belt 11. The first paper insertion mechanism 12 can open the cover or back cover of the book 200 and add a spacer between the cover and inner pages of the book 200, or between the back cover and inner pages of the book 200. Specifically, for example, the first paper insertion mechanism 12 includes a suction cup, a robotic arm, etc. to open the cover (or back cover) of the book 200, and after the cover (or back cover) is opened, inserts the spacer between the cover (or back cover) and the inner pages. The specific structure of the first paper insertion mechanism 12 will be described in detail in the following embodiments with reference to the accompanying drawings.

[0089] The flipping device 100 is located downstream of the first paper insertion mechanism 12, wherein the feed end 110 can be connected to the feed conveyor belt 11. After the first paper insertion mechanism 12 inserts a spacer between the cover (or back cover) and inner pages of the book 200, the flipping device 100 can flip the book 200 to a second position to facilitate the insertion of a spacer between the back cover (or cover) and inner pages of the book 200. In this embodiment, when the book 200 is in the first position, the first paper insertion mechanism 12 can be used to insert a spacer on one side of the book 200 (e.g., between the cover and inner pages). When it is necessary to insert a spacer on the other side of the book 200 (e.g., between the back cover and inner pages), it cannot be done by the first paper insertion mechanism 12. In this embodiment, the flipping device 100 is used to flip the book 200 to the second position to cooperate with the second paper insertion mechanism 13 to insert a spacer on the other side of the book 200.

[0090] The second paper insertion mechanism 13 is located downstream of the flipping device 100. The second paper insertion mechanism 13 can open the back cover or front cover of the book 200 and add a partition paper between the back cover and the inner pages of the book 200, or add a partition paper between the front cover and the inner pages of the book 200. Preferably, the structure of the second paper insertion mechanism 13 can be set to be the same as or similar to the structure of the first paper insertion mechanism 12.

[0091] Preferably, the angle at which the first paper insertion mechanism 12 and the second paper insertion mechanism 13 open the cover or back cover of the book 200 is less than 90°, so that after the book 200 leaves the range of the first paper insertion mechanism 12 and the second paper insertion mechanism 13, the opened cover or back cover can be closed under the action of gravity.

[0092] like Figure 6 As shown, according to a preferred embodiment of the present invention, the paper-adding device 10 further includes a discharge conveyor belt 14. The discharge conveyor belt 14 is located downstream of the flipping device 100, and the second paper-inserting mechanism 13 is located in the direction of movement of the discharge conveyor belt 14. The discharge conveyor belt 14 can drive the book 200 to the station of the second paper-inserting mechanism 13 in a second posture, and can also continue to transport the book 200 with paper added on both sides to the next station.

[0093] In a preferred embodiment of this utility model, the feeding conveyor belt 11 and the discharging conveyor belt 14 further include a guiding structure, which can adjust the position and orientation of the book 200 on the feeding conveyor belt 11 and the discharging conveyor belt 14. Preferably, the guiding structure is located upstream of the first paper insertion mechanism 12 and the second paper insertion mechanism 13, and after adjusting the position and orientation of the book 200, it cooperates with the first paper insertion mechanism 12 and the second paper insertion mechanism 13.

[0094] According to a specific embodiment of this utility model, the guiding structure includes at least one of a guide roller or a differential belt. For example, the guiding structure includes a guide roller, which is arranged parallel to the surface of the feed conveyor belt 11 along a direction perpendicular to the movement direction of the feed conveyor belt 11, and the rotational speed of the guide roller is controllable. When the book 200 moves to the position of the guide roller, by controlling the rotational speed of the guide roller, the movement speed of the book 200 at different positions along the feed conveyor belt 11 can be controlled, thereby changing the position and orientation of the book 200 relative to the feed conveyor belt 11.

[0095] In other embodiments, the guide structure may also include a differential belt, which is arranged along the movement direction of the feed conveyor belt 11, and can achieve different movement speeds in the movement direction perpendicular to the feed conveyor belt 11. When the book 200 moves to the position of the differential belt, by controlling the speed of the differential belt, the movement speed of the book 200 at different positions along the feed conveyor belt 11 can be controlled, thereby changing the position and orientation of the book 200 relative to the feed conveyor belt 11.

[0096] Preferably, the guide structure is configured to align the book opening of the book 200 with the movement direction of the feeding conveyor belt 11 and the discharging conveyor belt 14, and to face the first paper insertion mechanism 12 and the second paper insertion mechanism 13. Specifically, the position and orientation of the book 200 on the feeding conveyor belt 11 and the discharging conveyor belt 14 can be adjusted according to the working principles of the first paper insertion mechanism 12 and the second paper insertion mechanism 13.

[0097] Preferably, the structure and working principle of the first paper insertion mechanism 12 and the second paper insertion mechanism 13 are similar. For example... Figure 7As shown, in some embodiments of this utility model, the first paper insertion mechanism 12 and the second paper insertion mechanism 13 include a stop 15 and a robotic arm (not shown in the figure). The stop 15 is positioned on the movement path of the book 200 and blocks the movement direction of the book 200, causing the cover or back cover of the book 200 to open. Specifically, since the size of the hard cover in a hardcover book is usually larger than the size of the inner pages, in some embodiments, the stop 15 can be wedge-shaped, with the tip of the wedge pointing in the opposite direction to the movement direction of the book 200. As the book 200 moves along the feed conveyor belt 11 or the discharge conveyor belt 14, the stop 15 blocks the movement path of the book 200, using the wedge-shaped slope to allow the cover or back cover of the book 200 to open relative to the inner pages. Furthermore, the stop 15 is positioned on one side of the feed conveyor belt 11 or the discharge conveyor belt 14, with the book 200 positioned so that its foreground faces the stop 15. When the book 200 moves to the position of the stop 15, the cover or back cover opens at a certain angle, and a robotic arm retrieves the partition paper, adding it between the cover and inner pages of the book 200, or between the back cover and inner pages of the book 200. The book 200 continues to move along the feed conveyor belt 11 or the discharge conveyor belt 14, and after leaving the position of the stop 15, the cover or back cover closes under the action of gravity.

[0098] In other embodiments, the stop 15 can also be an elastic baffle, blocking the movement of the book 200 in the direction of motion. During the movement of the book 200, with the book opening facing the direction of motion, the elastic baffle abuts against the cover or back cover of the book 200, causing the cover or back cover to open. When the cover or back cover is opened to a certain extent, the elastic baffle experiences increased force and undergoes elastic deformation, causing the elastic baffle to detach from the cover or back cover, which then closes under the influence of gravity. In different embodiments, the first paper insertion mechanism 12 and the second paper insertion mechanism 13 can also operate on other principles, which will not be elaborated upon here.

[0099] Finally, it should be noted that the above descriptions are merely embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
