[0017] 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.

[0018] like Figures 1 to 4 As shown, this utility model provides a packing auxiliary device for automatically folding cardboard boxes, including a workbench 1 and a mounting frame 2 installed on the top of the workbench 1 by multiple screws. A first hydraulic rod 3 is mounted on the bottom of the mounting frame 2 via a mounting base, and the output end of the first hydraulic rod 3 is bolted to a pressure plate 4. The first hydraulic rod 3 drives the pressure plate 4 to press down to fix the cardboard placed on the top of the workbench 1 in the middle. A second hydraulic rod 5 is installed below the workbench 1, and the output end of the second hydraulic rod 5 is bolted to a connecting frame 6. The second hydraulic rod 5 can control the lifting and lowering of the connecting frame 6. A connecting plate 7 is provided on the right side of the connecting frame 6, and folding cylinders 8 are movably installed on the upper part of the side of the connecting frame 6 facing the connecting plate 7. During the upward movement of the connecting frame 6, two folding cylinders 8... The folding cylinder 8 pushes the corresponding side of the cardboard upward to fold it into a carton. The top of the workbench 1 has a slot corresponding to the folding cylinder 8. A stepper motor (not shown in the figure) is installed on the lower right side of the connecting frame 6, and the output end of the stepper motor is coaxially connected to the lead screw 9. The stepper motor can drive the lead screw 9 to rotate to drive the nut to move. The side wall of the lead screw 9 is equipped with a nut, and the side wall of the nut is fixedly sleeved with a connecting block 10. Two connecting rods 11 are symmetrically connected to the right side of the connecting block 10 relative to the lead screw 9. During the translation of the nut, the connecting block 10 and the connecting rods 11 will be translated, thereby moving the connecting plate 7 closer to or away from the connecting frame 6. In this way, the distance between the two folding cylinders 8 can be adjusted. The right end of the connecting rod 11 is connected to the corresponding side of the connecting plate 7 by a screw.

[0019] Specifically, multiple insertion rods 12 are connected side by side on the lower left side of the connecting plate 7, and the right side of the connecting frame 6 has insertion holes for the insertion rods 12. Multiple sets of this structure ensure that the connecting plate 7 can be moved stably.

[0020] Furthermore, two support rods 13 are symmetrically connected to the top of the pressure plate 4 relative to the first hydraulic rod 3, and the support rods 13 are movably inserted into the corresponding side of the mounting frame 2. The two support rods 13 can limit the lifting and lowering process of the pressure plate 4, so that the pressure plate 4 can be lifted and lowered smoothly.

[0021] Furthermore, a rubber film is glued to the bottom of the pressure plate 4, and the rubber film is flush with the edge of the pressure plate 4, which can prevent the pressure plate 4 from abrading the corresponding side of the cardboard.

[0022] It is worth noting that support legs 14 are welded to the four corners of the bottom of the workbench 1, and a base plate 15 is installed between the bottoms of the four support legs 14 by screws. This structure can stably support the workbench 1.

[0023] It is worth noting that the side wall of the second hydraulic rod 5 is fixedly fitted with a fixing seat, and the fixing seat is installed on the top of the base plate 15 by multiple screws, which can increase the stability of the second hydraulic rod 5 during operation.

[0024] It is worth mentioning that the base plate 15 is equipped with reinforcing plates 16 on both the front and rear sides, and the top of the reinforcing plates 16 is provided with multiple reinforcing holes arranged in a row. The addition of bolts in the reinforcing holes can increase the stability of the base plate 15 and thus increase the overall stability of the device.

[0025] The first hydraulic rod 3, the second hydraulic rod 5, and the stepper motor are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switches, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0026] Working principle: Place the cardboard at the top center of the workbench 1. The first hydraulic rod 3 controls the pressure plate 4 to press down and fix the middle of the cardboard placed on the top of the workbench 1. Then, the second hydraulic rod 5 controls the connecting frame 6 to move upward. During the upward movement of the connecting frame 6, the two folding cylinders 8 will push the two sides of the cardboard to fold upward. Then, the pressure plate 4 moves upward and rotates the cardboard 90°. Repeat this step to complete the folding of the other two sides of the cardboard, thus completing the folding of the carton.

[0027] When it is necessary to fold cartons of different sizes, the stepper motor drives the lead screw 9 to rotate, which in turn drives the nut to move horizontally. During the horizontal movement of the nut, the connecting block 10 and the connecting rod 11 will move horizontally, thereby moving the connecting plate 7 closer to or away from the connecting frame 6. In this way, the distance between the two folding tubes 8 can be adjusted, which can conveniently adjust the distance between the two folding tubes 8 to fold cartons of different sizes.
