Description

Technical Field

[0001] This utility model relates to the field of stacking technology, and in particular to a stacking machine. Background Technology

[0002] In the field of book production and processing, after books are bound, they need to be stacked in an orderly manner using stacking equipment to form neat stacks for subsequent packaging and storage.

[0003] Existing book stacking equipment, such as the authorized announcement number CN221274581U—a book stacking machine, has some design flaws. The width between the conveyor belts is fixed, which cannot adapt to the stable conveying of books of different widths. When the width of the book is greater than the spacing between the synchronous belts, the sides of the book will extend beyond the edge of the synchronous belt, and it is easy to tip over during conveying due to uneven force. When the width of the book is less than the spacing between the synchronous belts, the book will sway left and right between the two synchronous belts and deviate from the center, resulting in misalignment with subsequent components such as guide plates and pressure blocks.

[0004] Shaking or misalignment during transport accumulates in the stacking and pressing processes, causing misalignment at the edges when books are stacked and uneven stress during pressing. For example, narrow books may be squeezed from one side by the pressing blocks due to transport misalignment, ultimately increasing the risk of page wrinkling and cover damage. The system can only operate on books of a single size and cannot be flexibly adjusted for other book dimensions and specifications. When faced with books of different widths, heights, or shapes, it struggles to meet the practical needs of multi-size, high-frequency book production. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0055] Please refer to Figure 1-7 The stacking machine and stacking process in the embodiments of this utility model will now be described.

[0056] Please refer to Figure 1-2 This application provides a stacking machine, including a stacking adjustment mechanism 100, which includes a base 110, a conveying assembly 120, a supporting assembly 130, and a pressing assembly 140.

[0057] A conveyor assembly 120 is provided on the base 110;

[0058] The conveying component 120 is used to push the book onto the supporting component 130;

[0059] The support component 130 is located at the output end of the conveying component 120 and is used to receive books.

[0060] The pressing component 140 is positioned above the supporting component 130 to prevent the book from tipping over;

[0061] Both the conveying assembly 120 and the supporting assembly 130 have adjustable widths.

[0062] Specifically, during operation, the widths of the conveying assembly 120 and the supporting assembly 130 are first adjusted according to the size of the book to be processed, so that they are adapted to the size of the book. After adjustment, the conveying assembly 120 is driven to start working, conveying the book from left to right along the conveying path. When the book is conveyed to the supporting assembly 130, the book is lifted by other mechanisms, and the supporting assembly 130 supports the book, allowing it to fall smoothly onto the supporting assembly 130. At the same time, the pressing assembly 140 maintains appropriate pressure on the book on the supporting assembly 130. As the stacking height of the books increases, the pressing assembly 140 moves upward accordingly, always applying stable pressure to the stacked books to prevent the books from tilting or tipping over during the stacking process.

[0063] Two bases 110 are provided, arranged parallel from left to right along the book conveying direction. Both the conveying component 120 and the supporting component 130 are movably mounted on the bases 110. The spacing between the conveying component 120 and the supporting component 130 can be adjusted according to the book width to ensure stable book conveying, prevent tipping or shifting during conveying, and accurately support books of different widths. The pressing component 140 effectively prevents books from tipping over during stacking. This solves the technical problem of not being able to adapt to multiple book sizes, improves the adaptability and versatility for different book sizes, meets the actual needs of multi-size, high-frequency switching in book production, and helps improve the stability and efficiency of stacking operations.

[0064] The stacking adjustment mechanism 100 also includes an adjustment component 150, which includes a support base 151, a crank 152, a lead screw 153, a nut 154, a first slide rail 155, and two first sliders 156 slidably connected to the first slide rail 155. The support base 151 supports the lead screw 153. When the crank 152 is rotated, the crank 152 drives the lead screw 153 to rotate. The lead screw 153 adopts a forward and reverse thread design to ensure that the two nuts 154 can move synchronously towards or away from each other. The lead screw 153 drives the two nuts 154 to move synchronously along the axial direction of the lead screw 153. The nuts 154 drive the stacking guide plate 133 to move, thereby achieving precise adjustment of the spacing between the stacking guide plates 133. The first slide rail 155 is fixed on the support base 151, and the two first sliders 156 can move along the length direction of the first slide rail 155, which is perpendicular to the book conveying direction; thus, they play a guiding role in changing the spacing between the two stacking guide plates 133.

[0065] In another embodiment of this application, please refer to Figure 1-2 The support assembly 130 includes a backstop claw 131, a reset structure 132, and two parallel stacked guide plates 133.

[0066] The stacking guide plate 133 is provided with multiple long slots 1331. The anti-reverse claw 131 is set at the lower end of the stacking guide plate 133 through the reset structure 132. The anti-reverse claw 131 can penetrate into the long slots 1331 to receive books.

[0067] Specifically, slide rails are provided on the two bases 110, and two parallel stacking guide plates 133 are movably mounted on the two bases 110. The two parallel stacking guide plates 133 form a channel for stacking books and restrict the books from shifting left and right. Multiple long slots 1331 in the stacking guide plates 133 are connected front and back. The long slots 1331 provide space for the anti-reverse claws 131 to rotate in the front and back directions. The anti-reverse claws 131 are installed at the lower end of the stacking guide plates 133 through a reset structure 132, such as a spring. When a book enters the support component 130 from the conveying component 120, the book pushes the anti-reverse claw 131 to overcome the elasticity of the reset structure 132 and exit from the long slot 1331. After the book has completely entered the stacking channel, the anti-reverse claw 131 is reset under the action of the reset structure 132 and extends out of the long slot 1331 again. The top of the anti-reverse claw 131 supports the bottom of the book, completing the support of a single book. Subsequent books continue to enter, pushing the previous book to move upward. The next book presses the anti-reverse claw 131 below and exits the long slot 1331 again. After passing through, the anti-reverse claw 131 resets and supports multiple books, realizing the stacking of multiple books layer by layer.

[0068] In addition, multiple baffles are provided at one end of the stacking guide plate 133 near the conveying assembly 120. When the book is input from the conveying assembly 120, the baffles form a limiting channel. The width of the limiting channel composed of multiple baffles gradually decreases from the input end to the output end until it matches the width of the book. Above the input of the book, a sensing device is provided to detect whether the input book has any deviation. Two baffles are installed on the cylinder. After detecting a book with deviation, the cylinder drives the baffles to move. The baffles correct the slight deviation that may occur during the conveying process by lateral constraint, and guide the book to enter the stacking guide plate 133 along the central path to achieve correction.

[0069] In another embodiment of this application, please refer to Figure 1-2 The pressing assembly 140 includes a pressing block 141 and a driving assembly. The driving assembly is driven to the pressing block 141 to move the pressing block 141 up and down. The pressing block 141 is located above the anti-reverse pawl 131.

[0070] Specifically, the pressure block 141 is located above the anti-reverse claw 131, protruding from the long groove 1331, and is set in accordance with the book stacking area. It is used to press down the books. Through the continuous pressure of the pressure block 141, the upward tendency of the books during the stacking process is restrained, and the books are prevented from tipping over or tilting due to uneven stacking force.

[0071] In another embodiment of this application, please refer to Figure 1-2 The drive assembly includes a second slide rail 142, a first cylinder 143, and a movable connecting block 144;

[0072] The second slide rail 142 extends vertically and is disposed on the stacking guide plate 133. The movable connecting block 144 is movably disposed on the second slide rail 142. The pressing block 141 is rotatably connected to the movable connecting block 144. The first cylinder 143 is connected to the movable connecting block 144 to allow the pressing block 141 to move up and down.

[0073] Specifically, the second slide rail 142 is fixed on the stacking guide plate 133. The force of the first cylinder 143 is less than the force of lifting the book, maintaining stable pressure during the stacking process. According to the height of the book and the stacking requirements, when the stacking height increases, the pressing block 141 moves upward along the second slide rail 142 with the moving connecting block 144, realizing the rapid adjustment of the initial height of the pressing block 141, while ensuring the adaptive change of height during the stacking process, ensuring reasonable contact with the top of the book.

[0074] In another embodiment of this application, please refer to Figure 1-7 The drive assembly also includes a second cylinder 145, which is connected to the lower pressure block 141 and allows the lower pressure block 141 to rotate around the connection point with the movable connecting block 144.

[0075] Specifically, the second cylinder 145 is connected to the lower end of the pressing block 141 and is used to adjust the tilt angle of the pressing block 141. The cylinder body of the second cylinder 145 is hinged to the movable connecting block 144, and the piston rod of the second cylinder 145 is hinged to the end of the pressing block 141 away from the book. By extending and retracting the piston rod of the second cylinder 145, the pressing block 141 is driven to rotate around its connection point with the movable connecting block 144 to adjust the tilt angle of the pressing block 141. When the books are stacked to a set number, the piston rod of the second cylinder 145 extends, driving the pressing block 141 out of the long slot 1331, so that the books can be lifted out of the stacking adjustment mechanism 100.

[0076] A following adjustment plate 134 is provided at the lower end of the stacking guide plate 133. There are two following adjustment plates 134, which are respectively provided at the lower end of the two stacking guide plates 133. The following adjustment plate 134 moves with the stacking guide plate 133 to adjust the width. The following adjustment plate 134 is used to cooperate with other mechanisms. The holes on the following adjustment plate 134 play a guiding role. After adjusting the width, it is convenient to connect with other mechanisms.

[0077] In another embodiment of this application, please refer to Figure 1-7 It also includes a lifting mechanism 200, which is located below the stacking adjustment mechanism 100 and is used to lift books to the stacking adjustment mechanism 100. The lifting mechanism 200 includes an eccentric rod 210, a base plate 220, a bearing 230, a lifting connecting plate 240, a mounting base 250 and a push plate 260.

[0078] An eccentric rod 210 is rotatably mounted on a substrate 220, and a bearing 230 is provided above the eccentric rod 210.

[0079] The lower end of the lifting connecting plate 240 is provided with a through hole 241 for the bearing 230 to move. The through hole 241 allows the bearing 230 to move in the hole to drive the lifting connecting plate 240 to move up and down.

[0080] The mounting base 250 is movably disposed on the base plate 220 and is fixed to the upper end of the lifting connecting plate 240;

[0081] At least one push plate 260 is provided on the mounting base 250.

[0082] Specifically, the eccentric rod 210 rotates, and the through hole 241 provides movement space for the bearing 230. The bearing 230 moves within the through hole 241. Since the bearing 230 is installed at one end of the eccentric rod 210, the rotation of the eccentric rod 210 causes the movement trajectory of the bearing 230 to become circular. When the bearing 230 makes circular motion, it forces the lifting connecting plate 240 to make reciprocating linear motion in the vertical direction. The function of the through hole 241 is to accommodate the first component of the bearing 230's motion, thereby transmitting only the vertical component of the motion to the lifting connecting plate 240. That is, it converts the rotational motion into linear lifting motion, limits the lifting direction, improves accuracy, and ensures that the lifting connecting plate 240 drives the mounting base 250 to move stably up and down. Regardless of how the number of push plates 260 is adjusted, the consistency of the lifting action can be guaranteed, avoiding instability caused by adapting to different books. From the transmission level, it supports the adaptation and adjustment function of the support mechanism, reduces friction, and extends service life.

[0083] When the mounting base 250 moves along the base plate 220, the position of the mounting base 250 can be adjusted according to the lifting starting point of the book. In conjunction with the adjustment of the number of push plates 260, the spacing between the push plates 260 can be adjusted. The number of push plates 260 used can also be flexibly adjusted according to the size and number of books. For small books, only a single push plate 260 can be used; for large books, the number of push plates 260 can be increased to ensure that the contact area between the push plates 260 and the book is adapted, avoiding uneven force on the book or instability in lifting due to insufficient number of push plates 260. This further expands the adaptability range of the mechanism to different sizes of books. There is no need to replace the mounting base 250 or adjust the position of the entire mechanism. Finally, the lifting operation is performed by the push plates 260.

[0084] A cam follower 270 is provided between the mounting base 250 and the push plate 260, which is fitted with the hole on the follow adjustment plate 134 with a clearance fit. The clearance fit will not cause problems such as excessive tightness leading to obstructed movement or excessive looseness leading to shaking. It ensures that the guiding function is achieved and the lifting connecting plate 240 can move flexibly, while avoiding shaking caused by excessive clearance, thus balancing the flexibility and stability of movement.

[0085] In another embodiment of this application, please refer to Figure 1-5 It also includes a lifting and transporting mechanism 300 for transporting books stacked by the stacking adjustment mechanism 100. The lifting and transporting mechanism 300 includes a lifting mounting plate 310, a lifting connecting plate 320, a book lifting mechanism 330, a book pressing mechanism 340, and a first horizontal drive mechanism 350.

[0086] The first horizontal drive mechanism 350 is connected to the frame, and the lifting connecting plate 320 is connected to the first horizontal drive mechanism 350. The lifting connecting plate 320 is vertically set at the lower end of the lifting mounting plate 310. The first horizontal drive mechanism 350 drives the lifting connecting plate 320 to move so as to move the lifting mounting plate 310.

[0087] A book-lifting mechanism 330 for lifting books is provided below the lifting mounting plate 310;

[0088] Above the lifting mounting plate 310 is a book-pressing mechanism 340 for clamping the book with the book-lifting mechanism 330. The book-pressing mechanism 340 is configured corresponding to the book-lifting mechanism 330.

[0089] Specifically, the first horizontal drive mechanism 350 drives the lifting mounting plate 310 to move to one end near the stacking platform, so that the book lifting mechanism 330 is positioned below the stacked books. The book lifting mechanism 330 lifts the stacked books from below, and the book pressing mechanism 340 works with the book lifting mechanism 330 from above to clamp the books. The first horizontal drive mechanism 350 drives the lifting mounting plate 310 and the clamped books to move horizontally through the lifting connecting plate 320, and finally places the books stably on the conveyor belt. After the books are lifted, they are separated from the contact surface. There is no friction during the handling process, which realizes the lifting-type frictionless handling of books, improves the product appearance qualification rate, ensures the continuity of the production process, improves production efficiency, and is conducive to adapting to the stable operation requirements of automated production lines.

[0090] The book lifting mechanism 330 includes a first driving member 331 and a first pressure plate 332. The slide rail on the lifting connecting plate 320 provides vertical guidance and constraint for the first pressure plate 332. The first driving member 331 is configured as a cylinder, with the top of the piston rod connected to the lower surface of the first pressure plate 332. The first driving member 331 drives the first pressure plate 332 to move up and down along the slide rail. The driving force is transmitted in the vertical direction to ensure that the first pressure plate 332 remains horizontal during the lifting process and to prevent the book from tilting due to the offset of the pressure plate.

[0091] The book pressing mechanism 340 includes a second driving member 341 and a second pressing plate 342. The second driving member 341 drives the second pressing plate 342 to move up and down. By adjusting the distance between the second pressing plate 342 and the first pressing plate 332, it can adapt to the clamping requirements of books of different thicknesses.

[0092] The book pressing mechanism 340 also includes a third driving member 343 and a third pressing plate 344. The third driving member 343 drives the third pressing plate 344 to move up and down along the second slide rail 142, and the second driving member 341 drives the second pressing plate 342 to move up and down relative to the third pressing plate 344. The force of the third driving member 343 is greater than the force of the second driving member 341. During the process of lifting and translating the book, the third driving member 343 provides a downward pressing force, causing the third pressing plate 344 to move down, the second pressing plate 342 to press down, and the first pressing plate 332 to lift up. The second pressing plate 342 and the first pressing plate 332 clamp the book. The two-stage drive combined with the slide rail guide not only expands the clamping height adjustment range, but also ensures the stability of the movement process, and is suitable for books with greater thickness differences.

[0093] In another embodiment of this application, please refer to Figure 1-6 It also includes a translation and rotation mechanism 400, which is set in the process before the lifting mechanism 200. The translation and rotation mechanism 400 includes a translation and rotation mounting plate 410, a rotation drive mechanism 420, a lifting mechanism 430, a second horizontal drive mechanism 440, and a stroke adjustment block 450.

[0094] The translational and rotating mounting plate 410 is horizontally positioned between adjacent conveyor belts; the translational and rotating mounting plate 410 is equipped with a rotary drive mechanism 420 for driving the book to rotate horizontally;

[0095] Below the translational and rotating mounting plate 410 is a lifting mechanism 430 for adjusting the book clamping height in conjunction with the rotational drive mechanism 420;

[0096] A second horizontal drive mechanism 440 is provided below for conveying the book forward;

[0097] Below the translational and rotating mounting plate 410, there is also a stroke adjustment block 450, which is adjustablely positioned and connected to the second horizontal drive mechanism 440;

[0098] The rotary drive mechanism 420, the lifting mechanism 430, the second horizontal drive mechanism 440, and the stroke adjustment block 450 operate synchronously.

[0099] Specifically, the translational rotating mounting plate 410 is horizontally positioned between adjacent conveyor belts. Through the cooperation of the lifting mechanism 430 and the rotating drive mechanism 420, the book is lifted, clamped, and rotated horizontally. The second horizontal drive mechanism 440 transports the book forward during rotation. The stroke adjustment block 450 adjusts the stroke of the second horizontal drive mechanism 440, which solves the problems of separation between book turning and conveying processes, low efficiency, and poor adaptability. This improves the automation level and work efficiency of book turning and conveying, and facilitates flexible adjustment of process parameters according to different book sizes, thus improving adaptability.

[0100] The rotary drive mechanism 420 includes a fourth drive member 421, a pulley assembly 422, a transmission rod 423, an upper pressure plate 424, and a lower pressure plate 425. The upper pressure plate 424 is rotatably mounted above the translational rotary mounting plate 410. The translational rotary mounting plate 410 has a through hole in the middle, through which the transmission rod 423 is rotatably and vertically inserted. The top end of the transmission rod 423 is connected to the lower pressure plate 425. The upper pressure plate 424 and the lower pressure plate 425 are correspondingly arranged. A motor base is provided below the translational rotary mounting plate 410. The fourth drive member 421 is fixed on the motor base. The fourth drive member 421 drives the pulley assembly 422 to rotate the transmission rod 423.

[0101] Specifically, the fourth driving component 421 is located on the side of the translational and rotating mounting plate 410. The fourth driving component 421 is a servo motor. The power output of the fourth driving component 421 is transmitted to the transmission rod 423 through the pulley assembly 422. The transmission rod 423 drives the lower pressure plate 425 at the top to rotate. The lower pressure plate 425 drives the book to rotate through friction. The upper pressure plate 424 is correspondingly set with the lower pressure plate 425 to clamp the book and ensure that the book does not slip during rotation.

[0102] The turning beam is fixed above the translational and rotating mounting plate 410. When the upper pressure plate 424 moves along the vertical direction of the turning beam through the sliding structure, the distance between the upper pressure plate 424 and the lower pressure plate 425 can be adjusted to meet the clamping requirements of books of different thicknesses.

[0103] In another embodiment of this application, please refer to Figure 1 It also includes a first conveyor belt 500, and the translation and rotation mechanism 400 is also provided with a second conveyor belt 600. The first conveyor belt 500 is set in the process preceding the second conveyor belt 600.

[0104] Specifically, the second conveyor belt 600 has a higher speed than the first conveyor belt 500, which effectively solves the problems of book accumulation and friction in traditional conveyor belts of the same speed, reduces the damage rate to the appearance of books, and after the books have completed their rotation, they are conveyed by the second conveyor belt 600 to the top of the lifting mechanism 200.

[0105] Please refer to Figure 1-7 This application also provides a stacking process applicable to the aforementioned stacking machine, the stacking process comprising the following steps:

[0106] S1: Width adjustment: Adjust the width of the conveying component 120 of the stacking adjustment mechanism 100 and the distance between the two stacking guide plates 133 in the supporting component 130 according to the size of the books to be stacked, so that the books can pass through smoothly;

[0107] S2: Book transport: The first conveyor belt 500 continuously transports the books to be transported to the second conveyor belt 600 below the translation and rotation mechanism 400;

[0108] S3: Book rotation: The lifting mechanism 430 of the translation and rotation mechanism 400 lifts the book away from the second conveyor belt 600, the rotation drive mechanism 420 clamps the book and rotates it horizontally to a preset angle, and at the same time the second horizontal drive mechanism 440 drives the book to move along the movement direction of the second conveyor belt 600.

[0109] S4: Lifting Assist: When the book is conveyed above the lifting mechanism 200, the push plate 260 lifts the book;

[0110] S5: Stacking and receiving: When the book is lifted into the supporting component 130, the book lifting causes the anti-reverse claw 131 to retract into the long slot 1331. When the book is lifted above the anti-reverse claw 131, the reset structure 132 drives the anti-reverse claw 131 to reset, and the book falls down, with the anti-reverse claw 131 receiving the book. At the same time, the first cylinder 143 of the pressing component 140 drives the pressing block 141 to move down, pressing the top of the book from above to prevent the book from tipping over.

[0111] S6: Book Transfer: When the number of stacked books reaches the preset quantity, the lifting and transporting mechanism 300's first horizontal drive mechanism 350 drives the lifting mounting plate 310 to move under the stacked books. The piston rod of the second cylinder 145 extends, causing the lower pressing block 141 to exit the long slot 1331. The book pressing mechanism 340 cooperates with the book lifting mechanism 330 to clamp the stacked books. The books are then moved and output along with the first horizontal drive mechanism 350.

[0112] Specifically, in S1, each conveyor belt used for transporting books is adjusted according to the size of the books to be stacked; the worker turns the crank 152, causing the crank 152 to drive the lead screw 153 to rotate. Since the lead screw 153 adopts a forward and reverse thread design, the two nuts 154 drive the two stacking guide plates 133 to move synchronously towards or away from each other. The conveying assembly 120 set at the lower end of the two stacking guide plates 133 can adjust the spacing with the two stacking guide plates 133; the number of push plates 260 and the spacing between the push plates 260 are adaptively adjusted according to the size of the books to be stacked.

[0113] In S3, the lifting mechanism 430 is a lifting cylinder that moves the transmission rod 423 upward, causing the lower pressure plate to lift the book on the second conveyor belt 600. The upper pressure plate 424 and the lower pressure plate 425 work together to tighten the book. The fourth drive unit 421 outputs power, which is transmitted to the transmission rod 423 through the pulley assembly 422. The transmission rod 423 drives the lower pressure plate 425 at the top to rotate. The lower pressure plate 425 drives the book to rotate to a preset angle through friction. At the same time, the second horizontal drive mechanism 440 drives the book to move along the movement direction of the second conveyor belt 600. After the rotation is completed, the lifting mechanism 430 moves the transmission rod 423 downward, causing the book to fall onto the second conveyor belt 600 and enter the next process.

[0114] In S4, the motor drives the eccentric rod 210 to rotate. The lower end of the lifting connecting plate 240 is provided with a through hole 241 for the bearing 230 to move. Since the bearing 230 is installed at one end of the eccentric rod 210, the rotation of the eccentric rod 210 will make the movement trajectory of the bearing 230 become a circle. When the bearing 230 makes a circular motion, it will force the lifting connecting plate 240 to make a reciprocating linear motion in the up and down direction. The lifting connecting plate 240 drives the push plate 260 on the mounting base 250 to move up and down. The push plate 260 drives the book to move upward. After reaching a certain height, the push plate 260 moves downward.

[0115] In S5, the second slide rail 142 is fixed on the stacking guide plate 133. The force of the first cylinder 143 is less than the force of the book lifting, maintaining stable pressure during the stacking process. According to the book height and stacking requirements, when the stacking height increases, the pressing block 141 moves upward along the second slide rail 142 with the moving connecting block 144, realizing the rapid adjustment of the initial height of the pressing block 141, while ensuring the adaptive change of height during the stacking process, ensuring reasonable contact with the top of the book.

[0116] In S6, the first horizontal drive mechanism 350 drives the lifting mounting plate 310 to move to one end close to the stacking platform, so that the book lifting mechanism 330 corresponds to the bottom of the stacked books. The book lifting mechanism 330 lifts the stacked books from below, and the book pressing mechanism 340 cooperates with the book lifting mechanism 330 from above to clamp the books. The first horizontal drive mechanism 350 drives the lifting mounting plate 310 and the clamped books to move horizontally through the lifting connecting plate 320. A conveyor belt is set below the lifting and handling mechanism 300, and finally the books are placed stably on the conveyor belt.

[0117] This book stacking process covers width adjustment, conveying rotation, lifting stacking, and elevated transfer. It systematically optimizes traditional processes to address issues such as poor adaptability, easy book damage, unstable stacking, low efficiency, and large human error. Through a size adjustment design that eliminates the need for disassembly, it adapts to different book sizes and improves changeover efficiency. Relying on lift-and-remove rotation and elevated transfer, it eliminates frictional contact between books and equipment, reducing appearance damage. With the triple protection of lifting assistance, backstop claw 131 support, and pressure component 140 constraint, it prevents stacking deviation and tipping, reduces manual intervention, and ensures continuous production. Through multi-process linkage to compress the cycle time, it is adapted to the needs of high-speed printing production lines, balancing product qualification rate, production efficiency, and ease of operation.

[0118] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
