For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0051] Reference Figure 1 As a specific embodiment of the present invention, a printing page-turning device includes a clamping unit and a page-turning unit. The clamping unit includes a fixed plate 111. The page-turning unit includes a movable plate 121 and a first suction part 125. The plane of the movable plate 121 forms a preset angle with the plane of the fixed plate 111, and the movable plate 121 can move toward or away from the fixed plate 111. The first suction part 125 is fixed to the movable plate 121, enabling the cover of the printed matter to adhere to the inner side of the movable plate 121 at the angle formed by the fixed plate 111.

[0052] In this embodiment, the clamping unit supports and fixes the printed material, and the page-turning unit opens the cover of the printed material. It should be noted that the printed material can be any of a book, document, or brochure. Specifically, the clamping unit includes a fixing plate 111. The printed material can be placed on the fixing plate 111, with its back cover attached to the fixing plate 111, and the side of the printed material facing away from the fixing plate 111 serving as the cover. The plane of the movable plate 121 forms a preset angle with the plane of the fixing plate 111. The movable plate 121 can move towards the fixing plate, so that the inner side of the movable plate 121 forming the angle with the fixing plate 111 gradually approaches the cover of the printed material. The first suction part 125 ensures that the cover of the printed material is tightly attached to the inner side of the movable plate 121 forming the angle with the fixing plate 111. The movable plate 121 can move away from the fixing plate 111, thereby moving the cover and opening it. Overall, the clamping unit and the page-flipping unit work together to open the cover of printed materials, replacing manual opening. This not only saves labor costs but also greatly improves the efficiency of cover opening. Furthermore, it facilitates efficient and orderly post-processing, improving the overall efficiency of post-processing. In addition, compared to manual opening, it is less likely to leave creases or wrinkles on the paper, reducing the possibility of damage to the printed materials.

[0053] In one specific embodiment of the present invention, the preset included angle is 0-150 degrees, allowing the movable plate 121 to open at a relatively large angle relative to the fixed plate 111. This, in turn, allows the opened cover and other parts of the printed material to open at a larger angle, which is beneficial for subsequent sample insertion. Simultaneously, it also makes the printed material turning device suitable for printed materials of different thicknesses. The fixed plate 111 is inclined, with its plane forming an angle of 30-75 degrees with the vertical direction. This causes the printed material placed on the fixed plate to also be inclined. At this time, the foreground of the printed material faces upwards and the spine faces downwards, facilitating the opening of the cover and effectively improving the efficiency of opening.

[0054] In a specific embodiment of the present invention, the page-turning unit further includes a second adsorption part 122, which is also fixed to the movable plate. Specifically, a first adsorption part 125 is fixed to the middle of the movable plate, and four second adsorption parts 122 are fixed at the four corners of the movable plate 121. The first adsorption part 125 allows the cover to actively adhere to the inner side of the movable plate 121. The second adsorption part 122 makes the movable plate 121 and the cover fit more tightly. In this way, the cover is not easily separated from the movable plate 121 when it is turned open, making the turning process efficient and stable, and ensuring the efficiency of the cover turning. The clamping unit also includes a third adsorption part 112. The third adsorption part 112 is fixed to the fixed plate 111, which allows the back cover of the printed material to be tightly attached to the inner side of the angle formed by the fixed plate 111 and the movable plate 121, effectively improving the stability of the printed material position, making it less likely for the printed material to fall off the fixed plate 111, thereby ensuring the efficiency of post-processing.

[0055] In a specific embodiment of the present invention, the first adsorption part 125 is a hollow structure, with its axis perpendicular to the plane of the movable plate 121. One end of the first adsorption part 125 is an air outlet, coexisting with the inner surface of the movable plate 121 in the same plane, and the other end is an air inlet. Furthermore, the size of the first adsorption part 125 is larger than that of the second adsorption part 122. The second adsorption part 122 is a hollow structure, with its axis perpendicular to the plane of the movable plate 121. One end of the second adsorption part 122 is an intake end, coexisting with the inner surface of the movable plate 121 in the same plane, and the other end is an exhaust end. The third adsorption part 112 is also a hollow structure, with its axis perpendicular to the plane of the fixed plate. One end of the third adsorption part 112 is an intake end, coexisting with the inner surface of the fixed plate 111 in the same plane, and the other end is an exhaust end. This allows the back cover and front cover of the printed material to be laid relatively flat on the fixed plate 111 and the movable plate 121, respectively. During page turning, the cover is less prone to wrinkling. The first adsorption section 125 has its air inlet connected to a first compressed air source. It should be noted that the first compressed air source blows compressed air into the first adsorption section, and the compressed air swirls within the first adsorption section, generating an adsorption force that causes the cover to move towards the air outlet of the first adsorption section 125 and the inner surface of the movable plate 121, and adhere to the movable plate. When the first compressed air source stops supplying air, the cover is released. The second adsorption section 122 has its suction outlet connected to a first vacuum pumping device. When the cover of the printed material adheres to the inner surface of the movable plate 121, the first vacuum pumping device evacuates air from the second adsorption section 122 to make the cover adhere more tightly to the inner surface of the movable plate. The third adsorption section 112 has its suction outlet connected to a second vacuum pumping device, which evacuates air from the third adsorption section 112. It should be noted that when opening the cover of the printed material, firstly, the second vacuum pump is turned on to evacuate the third adsorption section 112, allowing the printed material to remain more firmly on the fixed plate 111. Then, the first compressed air source is turned on to blow air into the first adsorption section 125, so that the cover can adhere to the inner side of the movable plate 121. Finally, the first vacuum pump is turned on, and under the action of the first vacuum pump, the second adsorption section 122 generates suction. In addition, filters are provided at the suction end of each first adsorption section 125, the second adsorption section 122, and the third adsorption section 112 to prevent impurities from entering the first adsorption section 125, the second adsorption section 122, and the third adsorption section 112, reducing the possibility of blockage and enabling the adsorption section to work stably for a long time.

[0056] In a specific embodiment of the present invention, a first clearance hole is provided in the middle of the movable plate 121, and a second clearance hole is provided at each of the four corners. The first clearance hole can avoid the first adsorption part 125, and the second clearance hole can avoid the second adsorption part 122. A third clearance hole is provided on the fixed plate 111. The third clearance hole can avoid the third adsorption part 112. There are multiple third clearance holes, which are evenly distributed along the length direction of the fixed plate 111. It should be noted that the length direction of the fixed plate 111 is the same as the extension direction of the spine of the printed matter. The length direction of the movable plate 121 is also the same as the extension direction of the spine of the printed matter. A first adsorption part 125 is fixed in the first clearance hole, and a second adsorption part 122 is fixed in each second clearance hole. The air outlet end of the first adsorption part 125 and the suction end of the second adsorption part 122 are on the same plane as the inner surface of the movable plate 121. This allows the cover of the printed material to adhere more tightly to the inner surface of the movable plate 121. A third suction part 112 is fixed within each third clearance hole. Furthermore, the suction end of the third suction part 112 is flush with the inner surface of the fixed plate 111, further ensuring a tighter fit between the back cover of the printed material and the inner surface of the fixed plate 111. This significantly improves the stability of the printed material, making it less likely to detach from the fixed plate 111, thereby improving post-processing efficiency.

[0057] In a specific embodiment of the present invention, the page-turning unit further includes a first driving mechanism 123, which is located on the outer side of the angle formed between the movable plate 121 and the fixed plate 111. The first driving mechanism 123 includes a driving cylinder, guide rods, and transmission rods. The output shaft of the driving cylinder faces the outer side of the angle formed between the movable plate 121 and the fixed plate 111. Two guide rods are arranged opposite each other, both located between the driving cylinder and the movable plate 121, with one end extending towards the driving cylinder and the other end extending towards the movable plate 121. Two transmission rods are also located between the driving cylinder and the movable plate 121, with one end fixedly connected to the output shaft of the driving cylinder and the other end rotatably connected to the outer side of the angle formed between the movable plate 121 and the fixed plate 111. One transmission rod is slidably connected to one of the guide rods at its connection end with the driving cylinder, and the other transmission rod is slidably connected to the other guide rod at its connection end with the driving cylinder. The driving cylinder is connected to a compressed air source, which provides compressed gas to enable the driving cylinder to operate. The drive cylinder can drive one end of the transmission rod to move along the guide rod, so that the other end of the transmission rod can drive the movable plate 121 to flip. A guide hole is provided on the guide rod, and an insert rod is fixed at the connection end between the transmission rod and the drive cylinder. The insert rod is adapted to the guide hole, and its two ends are slidably engaged in the guide holes of the two guide rods respectively. Overall, the structure is relatively simple and greatly improves the efficiency of opening the cover.

[0058] In one specific embodiment of the present invention, the page-turning unit further includes a support plate 124. The support plate 124 is located below the movable plate 121 and the fixed plate 111. It should be noted that a paper-dropping cylinder is provided on the outer side of the angle formed between the fixed plate 111 and the movable plate 121. The paper-dropping cylinder is fixedly connected to one end of the support plate, and it can drive the entire support plate to move to the side of the fixed plate 111 away from the movable plate 121, so that the printed matter on the fixed plate 111 can fall.

[0059] In one specific embodiment of the present invention, the clamping unit further includes an air blowing section 113, specifically, the air blowing section 113 is a nozzle, which is connected to a second compressed air source. The second compressed air source can blow air onto the air blowing section 113. The fixing plate 111 has a square structure. There are two air blowing sections 113, which are arranged opposite each other and fixed to opposite ends of the fixing plate 111. The air blowing section 113 can blow air onto the printed matter fixed on the fixing plate 111 to loosen the paper from each other, which is beneficial for subsequent page turning operations and effectively improves page turning efficiency.

[0060] In a specific embodiment of the present invention, the clamping unit further includes support legs 114. Support legs 114 can support and fix the fixing plate 111, resulting in high stability of the fixing plate 111's position. There are two support legs 114, both vertically arranged. The top of one leg is fixedly connected to one end of the fixing plate 111 via an adjusting bolt, and the top of the other leg is fixedly connected to the other end of the fixing plate 111 via an adjusting bolt. It should be noted that the angle between the plane of the fixing plate 111 and the vertical direction is adjustable; that is, the tilt angle of the fixing plate 111 is adjustable. The tilt angle of the fixing plate 111 can be adjusted by rotating the adjusting bolt to accommodate printed materials of different thicknesses, making the page-turning device more versatile. This also facilitates page-turning operations and improves page-turning efficiency. Furthermore, each support leg 114 includes an inner adjusting rod and an outer adjusting rod. The top of the inner adjusting rod is fixedly connected to the top of the fixing plate 111, and an adjusting hole is provided at the bottom. An adjusting hole is also provided at the bottom of the outer adjusting rod. The lower parts of the inner and outer adjusting rods are fixedly connected by bolts through the adjusting holes. Loosening the adjusting bolts allows the inner adjusting rod to move up and down, thereby adjusting the height of the fixed plate 111, which facilitates page turning operations.

[0061] In one specific embodiment of the present invention, the printed matter turning device further includes an alignment unit. Before the cover is turned open, the alignment unit acts on the opposite ends of the printed matter, aligning the opposite ends of the printed matter with the opposite ends of the fixed plate, reducing the possibility of the cover shifting along the length of the fixed plate 111. Specifically, the alignment unit includes baffles 131 and second driving mechanisms 132. There are two baffles 131, respectively located at opposite ends of the movable plate 121. The shape of the movable plate 121 is also adapted to the shape of the printed matter, and its size is smaller than the size of the cover of the printed matter. In this embodiment, the movable plate 121 is a square structure. In some other embodiments, the movable plate is a circular structure, a triangular structure, or a rhomboid structure, etc. There are two second driving mechanisms 132, respectively located below the opposite ends of the movable plate 121, corresponding one-to-one with the baffles 131. Each second driving mechanism 132 includes a paper-aligning electromagnet and a third guide rod. The paper-aligning electromagnet is located below the movable plate 121, and its output shaft extends along the length of the movable plate 121, being fixedly connected to the side of the baffle 131 near the movable plate 121. A third guide rod extends along the length of the movable plate 121, and a mounting groove adapted to the third guide rod is provided at the bottom of the baffle 131, allowing the bottom of the baffle 131 and the third guide rod to be slidably connected via the mounting groove. It should be noted that the paper-aligning electromagnet is electrically connected to an external power source, which provides power. The paper-aligning electromagnet can drive the baffle 131 to move towards or away from the movable plate 121. By adjusting the distance between the two baffles 131, the alignment unit can be adapted to printed materials of different lengths, effectively enhancing the versatility of the alignment unit and thus the versatility of the printing material turning device. Furthermore, each baffle has clearance notches on the upper and lower parts of one side to form a clearance structure, which facilitates the use of the printing material turning device with other post-processing equipment.

[0062] In one specific embodiment of the present invention, the printing page turning device further includes a base plate 140, and the clamping unit, page turning unit, and alignment unit are fixed to the top surface of the base plate 140. This facilitates the overall transfer of the printing page turning device. Rotating shafts are provided at opposite ends of the bottom of the movable plate 121, and bearings are also provided at opposite ends of the bottom of the movable plate 121. The opposite ends of the lower part of the movable plate 121 are fixedly connected to the base plate 140 via rotating shafts and bearings, enabling the movable plate 121 to rotate stably and efficiently.
