[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model provides a technical solution: a box top adsorption structure for a bottom folding box machine, comprising a mounting plate 1, one end of the mounting plate 1 is fixedly connected to a slide cylinder 2, a fixed frame 3 is provided on one side of the slide cylinder 2, and a lifting auxiliary mechanism 5 is provided between one end of the fixed frame 3 and the output end of the slide cylinder 2, a negative pressure adsorption mechanism 6 is provided inside the fixed frame 3, and a top folding mechanism 7 is provided at the other end of the fixed frame 3, the top end of the fixed frame 3 is opened, and the top end of the fixed frame 3 is connected to a cover plate 4 by bolts.

[0023] According to the overall structure of the device, the slide cylinder 2 can drive the adsorbed paper box to move conveniently, so as to drive the paper box to the corresponding position, which is convenient for subsequent operations. The fixed frame 3 and the cover plate 4 are connected by detachable bolts, which can drive the fixed frame 3 and the cover plate 4 to be easily disassembled, so as to facilitate maintenance of the internal structure of the fixed frame 3.

[0024] like Figure 1 and Figure 2 As shown, the lifting auxiliary mechanism 5 includes a lifting cylinder 501 fixedly connected to the output end of the sliding rod cylinder 2, the bottom end of the lifting cylinder 501 is fixedly connected to a connecting plate 502, and one end of the connecting plate 502 is fixedly connected to a fixed plate 503, and the end of the fixed plate 503 away from the connecting plate 502 is fixedly connected to the fixed frame 3, the output end of the sliding rod cylinder 2 is fixedly connected to a pair of U-shaped plates 504, and the inner walls of the pair of U-shaped plates 504 are fixedly connected with built-in rods 505, the outer walls of the pair of built-in rods 505 are both sleeved with movable sleeve blocks 506, and one end of the pair of movable sleeve blocks 506 is fixedly connected to the end of the fixed plate 503 close to the connecting plate 502.

[0025] Through the setting of the lifting auxiliary mechanism 5, the slide cylinder 2 drives the fixed plate 503 to move downward through the connecting plate 502, so that the fixed plate 503 drives the fixed frame 3 to move downward with the assistance of the movable sleeve block 506, and the pair of vacuum suction cups 601 move downward until they contact the box blank. Then the slide cylinder 2 drives the fixed plate 503 and the fixed frame 3 to move upward, so that the pair of vacuum suction cups 601 drive the box blank to open into a rectangular box shape, so as to facilitate the subsequent folding operation on the side of the paper box.

[0026] like Figure 1 and Figure 3 As shown, the negative pressure adsorption mechanism 6 includes a pair of vacuum suction cups 601, and an air guide tube 602 is fixedly connected between the top of the pair of vacuum suction cups 601 and the bottom end of the fixed frame 3. The inner bottom end of the fixed frame 3 is fixedly connected to a pair of built-in cylinders 603, and the top of the air guide tube 602 passes through the bottom end of the fixed frame 3 and is fixedly connected to the bottom end of the built-in cylinder 603. The interior of the pair of built-in cylinders 603 is slidably connected to a piston plate 604, and the top of the piston plate 604 is fixedly connected to a movable rod 605. A sliding plate 606 is slidably connected between the inner walls of the fixed frame 3, and a first electric telescopic rod 607 is fixedly connected between the bottom end of the sliding plate 606 and the inner bottom end of the fixed frame 3. Circular holes are drilled in the inner top ends of the pair of built-in cylinders 603, and the top end of the movable rod 605 passes through the circular holes and is fixedly connected to the bottom end of the sliding plate 606. The inner walls of the pair of circular holes are fixedly connected to a sealing ring 9, and the inner wall of the sealing ring 9 is in close contact with the outer wall of the movable rod 605.

[0027] Through the setting of the negative pressure adsorption mechanism 6, after the pair of vacuum suction cups 601 come into contact with the box blank, the first electric telescopic rod 607 pushes the sliding plate 606 to move upward, so that it drives the pair of movable rods 605 and the piston plate 604 to move upward, causing the space between the bottom end of the piston plate 604 and the bottom end of the built-in cylinder 603 to increase, and as the piston plate 604 moves upward, the air inside the vacuum suction cup 601 and the air guide tube 602 is drawn upward to replenish the space between the bottom end of the piston plate 604 and the bottom end of the built-in cylinder 603 The inside of the vacuum suction cup 601 forms a low-pressure area, which produces a pressure difference with the external air pressure, causing gas molecules to flow from the outside to the inside of the vacuum suction cup 601. The gas molecules are adsorbed on the surface of the vacuum suction cup 601 to form vacuum adsorption, thereby achieving adsorption of the box blank. The overall structure is relatively small and convenient, and can be effectively used in the use scenario of small paper box folding. It is easy to use and has good use effect. The setting of the sealing ring 9 can seal the gap between the movable rod 605 and the circular hole to reduce gas leakage.

[0028] like Figure 1 and Figure 4 As shown, the top folding mechanism 7 includes a second electric telescopic rod 701, a pair of fixed blocks 702 are fixedly connected between the outer wall of the second electric telescopic rod 701 and the other end of the fixed frame 3, the other end of the fixed frame 3 is fixedly connected to a hinge 703, and one end of the hinge 703 is fixedly connected to a connecting long block 704, the bottom end of the second electric telescopic rod 701 is fixedly connected to a connecting block 706, and the bottom end of the connecting block 706 is fixedly connected to a sleeve frame 705, and the inner wall of the sleeve frame 705 is rotatably connected to the outer wall of the connecting long block 704.

[0029] Through the setting of the top folding mechanism 7, the second electric telescopic rod 701 drives the sleeve frame 705 to move downward, so that it drives the connecting long block 704 to fold downward 90 degrees with the assistance of the hinge 703, driving the top surface of the box to fold downward, assisting the box folding operation, so as to facilitate the rapid folding work and improve the box folding efficiency.

[0030] like Figure 1 As shown, two pairs of mounting holes 8 are drilled at one end of the mounting plate 1 , and the two pairs of mounting holes 8 are respectively located at the top and bottom of the slide rod cylinder 2 .

[0031] By setting the mounting holes 8 and cooperating with corresponding mechanical fasteners, the mounting plate 1 can be driven to be mounted on the bottom buckle box folding machine, so as to drive the entire box top adsorption mechanism to be mounted on the bottom buckle box folding machine for use.

[0032] Working principle: After the box blank is conveyed over, the sliding cylinder 2 drives the fixed plate 503 to move downward through the connecting plate 502, and the corresponding pair of movable sleeves 506 move synchronously along the built-in rod 505, and the auxiliary fixed plate 503 drives the fixed frame 3 and a pair of vacuum suction cups 601 to move downward steadily until the vacuum suction cups 601 come into contact with the box blank, and then the first electric telescopic rod 607 pushes the sliding plate 606 to move upward, so that it drives a pair of movable rods 605 and the piston plate 604 to move upward, causing the space between the bottom end of the piston plate 604 and the bottom end of the built-in cylinder 603 to increase, and as the piston plate 604 moves upward, the air inside the vacuum suction cup 601 and the air guide tube 602 is drawn upward and replenished in the space between the bottom end of the piston plate 604 and the bottom end of the built-in cylinder 603, so that the vacuum suction cup 601 and the air guide tube 602 are drawn upward and replenished in the space between the bottom end of the piston plate 604 and the bottom end of the built-in cylinder A low-pressure area is formed inside the empty suction cup 601, and a pressure difference is generated between the empty suction cup 601 and the external air pressure. The pressure difference is used to drive the vacuum suction cup 601 to adsorb the box blank. Then, the slide cylinder 2 drives the fixed plate 503 and the fixed frame 3 to move upward, so that the pair of vacuum suction cups 601 drive the box blank to open into a rectangular box shape. Next, the bottom folding machine folds multiple surfaces of the rectangular paper box, and the second electric telescopic rod 701 drives the sleeve frame 705 to move downward, so that it drives the connecting long block 704 to fold downward 90 degrees with the assistance of the hinge 703, and drives the top surface of the box to fold downward to assist in folding. After the paper box is folded, the slide cylinder 2 can drive the folded paper box to move to the discharge area, and drive the first electric telescopic rod 607 to reset, so that the pair of vacuum suction cups 601 cancel the adsorption and fixation of the paper box.

[0033] The wiring diagram of the slide cylinder 2, the lifting cylinder 501, the first electric telescopic rod 607, and the second electric telescopic rod 701 in this solution is common knowledge in the art. Their operating principles are already known technologies, and their models are selected according to actual use. Therefore, the control method and wiring layout of the slide cylinder 2, the lifting cylinder 501, the first electric telescopic rod 607, and the second electric telescopic rod 701 will not be explained in detail.
