[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 and Figure 4This utility model provides a technical solution: a corrugated paper folding mechanism, including a worktable 1, a groove 2 provided at the upper end of the worktable 1, a flipping mechanism 3 provided on both sides of the inner wall of the groove 2, a fixing plate 4 fixedly connected to both sides of the upper end of the worktable 1, a limit block 5 fixedly connected to both sides of the upper end of the fixing plate 4, a corrugated cardboard 6 movably connected to the inner side of the limit block 5, a mounting frame 7 fixedly connected to the rear side of the upper end of the worktable 1, a cylinder 8 detachably connected to the upper end of the mounting frame 7, an adjusting mechanism 9 fixedly connected to the telescopic end of the cylinder 8, and an adjusting mechanism 9 on both sides of the upper end of the adjusting mechanism 9. A sliding rod 10 is fixedly connected. The flipping mechanism 3 includes a pressure plate 31. One side of the pressure plate 31 is fixedly connected to one side of the inner wall of the groove 2. The upper end of the pressure plate 31 is provided with a movable groove 32. One side of the bottom wall of the movable groove 32 is provided with a pressure groove 33. A rotating rod 34 is rotatably connected to the middle of the inner wall of the movable groove 32. A flipping plate 35 is sleeved on the outer wall of the rotating rod 34. A support protrusion 36 is fixedly connected to one side of the upper end of the pressure plate 31. The outer wall of the groove 2 is embedded and connected to the upper end of the workbench 1. One side of the flipping mechanism 3 is detachably connected to one side of the inner wall of the groove 2.

[0023] The operator places the corrugated cardboard 6 on the workbench 1 and then activates the cylinder 8 on the mounting frame 7. After the cylinder 8 is activated, the lifting plate 91 descends. At this time, the lifting plate 91 moves stably up or down under the action of the slide rod 10. During the movement, the lifting plate 91 drives the two pressing blocks 94 to descend and press down on the position on the corrugated cardboard 6 that needs to be crimped. When the pressing blocks 94 press down, they press the two sides of the corrugated cardboard 6 into the crimping plate 31 and into the crimping groove 33. When the corrugated cardboard 6 is under pressure, it simultaneously applies pressure to the inside of the flipping plate 35 inside the movable groove 32, so that the flipping plate 35 rotates inward with the rotating rod 34 as the rotation point, and pushes the two ends of the corrugated cardboard 6 that need to be folded upward, so that the surface of the corrugated cardboard 6 is left with obvious indentations, which facilitates subsequent use. The corrugated cardboard 6 is movablely connected to the inside of the limiting block 5, so that the corrugated cardboard 6 can be flipped and folded as needed.

[0024] Please see Figure 2 In order to quickly flip the corrugated cardboard 6 on both sides of the crease plate 31, the upper end of the crease plate 31 is embedded and connected to the outer wall of the movable groove 32, and one side of the bottom wall of the movable groove 32 is embedded and connected to the top wall of the crease groove 33. The movable groove 32 and the crease groove 33 are set as an integral structure.

[0025] The telescopic end of cylinder 8 is detachably connected to lifting plate 91, ensuring flexible replacement and maintenance of cylinder 8. The adjustment mechanism 9 allows operators to precisely adjust the corrugated cardboard 6 according to its thickness and required folding depth to achieve the best folding effect. The slide bar 10 ensures the stability and accuracy of lifting plate 91 during operation. The movable groove 32 and crease groove 33 on the crease plate 31 ensure precise alignment of corrugated cardboard 6 during folding, guaranteeing folding quality. The combination of rotating rod 34 and flipping plate 35 enables rapid flipping of corrugated cardboard 6, improving work efficiency. The support protrusion 36 provides additional support for corrugated cardboard 6, preventing deformation during folding. The operation is simple and can effectively improve the folding efficiency and quality of corrugated cardboard 6.

[0026] Please see Figure 3 In order to quickly fix the lower pressure block 94 onto the lifting plate 91, the adjusting mechanism 9 includes a lifting plate 91. The upper end of the lifting plate 91 is fixedly connected to the telescopic end of the cylinder 8. A motor 92 is provided on one side of the lifting plate 91. A bidirectional screw 93 is provided on the output shaft of the motor 92. The lower pressure block 94 is threadedly connected to both sides of the outer wall of the bidirectional screw 93. Moving grooves 95 are embedded and connected to both sides of the lower end of the lifting plate 91. Guide rods 96 are fixedly connected to both sides of the inner wall of the moving groove 95. Scale lines 97 are fixedly connected to both sides of the front end of the lifting plate 91. A pointer 98 is fixedly connected to the front end of the lower pressure block 94. One side of the lifting plate 91 is detachably connected to one side of the motor 92. The output shaft of the motor 92 is drivenly connected to one side of the bidirectional screw 93. One end of the bidirectional screw 93 passes through the lifting plate 91, extends through the lower pressure block 94 to one side of the moving groove 95, and is rotatably connected to it.

[0027] The operator adjusts the position of the lower pressure block 94 on the bidirectional screw 93 according to the required crease position of the corrugated cardboard 6. Then, based on the position of the lower pressure block 94, the operator adjusts the position of the crease plate 31 so that the crease groove 33 inside the crease plate 31 is aligned with the lower pressure block 94, thus facilitating crease application. By controlling the start of the motor 92, the output shaft of the motor 92 drives the bidirectional screw 93 to rotate. At this time, the lower pressure blocks 94 move relative to each other or away from each other along the guide rod 96. In addition, the operator can observe the scale line 97 to ensure the distance between the lower pressure blocks 94. When the lower pressure blocks 94 move, they simultaneously drive the pointer 98. The device can be moved for easy observation. Based on the folding requirements of the corrugated cardboard 6, the motor 92 can be stopped and started. Then, the position of the limiting block 5 on the fixing plate 4 is adjusted, which serves to limit and position the corrugated cardboard 6 when it is placed, thus facilitating its use. Since the lower pressure block 94, the crease plate 31, and the limiting block 5 are all detachable, they can be easily adjusted within a specified range according to the size of the corrugated cardboard 6 and the crease position, making it convenient to use and expanding its adaptability. This allows for precise folding and flipping of the corrugated cardboard 6, thereby improving production efficiency and product quality.

[0028] Working principle: First, the operator places the corrugated cardboard 6 on the workbench 1, then activates the cylinder 8 on the mounting frame 7. After the cylinder 8 is activated, the lifting plate 91 descends. At this time, under the action of the sliding rod 10, the lifting plate 91 moves stably upwards or downwards. During the movement, the lifting plate 91 drives two lowering blocks 94 to descend and press down on the positions on the corrugated cardboard 6 where creasing is needed. When the lowering blocks 94 press down, they press both sides of the corrugated cardboard 6 into the creasing plate 31 and into the creasing groove 33. When the corrugated cardboard 6 is under pressure, it simultaneously applies pressure to the inner side of the flipping plate 35 inside the movable groove 32, causing the flipping plate 35 to rotate inwards around the rotating rod 34, and pushing upwards at the folding points on both ends of the corrugated cardboard 6. This leaves obvious indentations on the surface of the corrugated cardboard 6, facilitating subsequent use. The corrugated cardboard 6 is limited by... The movable connection on the inner side of block 5 allows corrugated cardboard 6 to be flipped and folded as needed. The telescopic end of cylinder 8 is connected to lifting plate 91 in a detachable manner, ensuring flexible replacement and maintenance of cylinder 8. The setting of adjustment mechanism 9 allows the operator to make precise adjustments according to the thickness of corrugated cardboard 6 and the required folding depth to achieve the best folding effect. The setting of slide bar 10 ensures the stability and accuracy of lifting plate 91 during operation. The setting of movable groove 32 and crease groove 33 on crease plate 31 allows corrugated cardboard 6 to be precisely aligned during folding, ensuring folding quality. The combination of rotating rod 34 and flipping plate 35 enables rapid flipping of corrugated cardboard 6, improving work efficiency. The setting of support protrusion 36 provides additional support for corrugated cardboard 6 to prevent deformation during folding. The operation is simple and can effectively improve the folding efficiency and quality of corrugated cardboard 6.

[0029] Then, the operator adjusts the position of the lower pressure block 94 on the bidirectional screw 93 according to the required crease position of the corrugated cardboard 6. The position of the crease plate 31 is then adjusted according to the position of the lower pressure block 94, aligning the crease groove 33 inside the crease plate 31 with the lower pressure block 94 for easier crease application. The motor 92 is started, and its output shaft drives the bidirectional screw 93 to rotate. At this time, the lower pressure blocks 94 move relative to each other or away from each other along the guide rod 96. Furthermore, the operator can observe the scale line 97 to ensure the distance between the lower pressure blocks 94. As the lower pressure blocks 94 move, the pointer 98 also moves, facilitating observation and adjustment according to the folding requirements of the corrugated cardboard 6. To start the device, stop motor 92 and then adjust the position of the limiting block 5 on the fixing plate 4. This allows the corrugated cardboard 6 to be placed and positioned, facilitating its use. Since the lower pressing block 94, the crease plate 31, and the limiting block 5 are all detachable, they can be easily adjusted within a specified range according to the size of the corrugated cardboard 6 and the crease position, making it more convenient to use and adaptable to a wider range. This allows for precise folding and flipping of the corrugated cardboard 6, thereby improving production efficiency and product quality. The above is the working process of the entire device. Any content not described in detail in this manual is existing technology known to those skilled in the art.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
