[0026] Self-positioning mechanism 5: It includes an electro-hydraulic push rod 3 53, a connecting seat 54, a longitudinal limit assembly 55 and a transverse limit assembly 56. The electro-hydraulic push rod 3 53 is respectively arranged on the front and rear sides of the punching shell 1. The telescopic ends of the electro-hydraulic push rod 3 53 are provided with connecting seats 54. The interior of the connecting seats 54 is respectively provided with longitudinal limit assemblies 55 and transverse limit assemblies 56. The self-positioning mechanism 5 also includes an electro-hydraulic push rod 2 51 and a preliminary limit seat 52. The electro-hydraulic push rod 2 51 is arranged on the left ends of the front and rear sides of the punching shell 1.

The bottom wall of the perforated shell 1 is provided with symmetrically distributed avoidance grooves, and the feeding roller 62 is installed in coordination with the avoidance grooves. The front end of the rotating shaft is provided with a pulley 63, and the pulleys 63 are connected through a belt 64. A motor 65 is provided on the rear side of the fixed seat 61 at the left end of the rear side, and the input end of the motor 65 is electrically connected to the output end of the single-chip computer 2, and the output shaft of the motor 65 is fixedly connected to the rear end of the rotating shaft on the left side. When the packaging box moves to the right side of the bottom wall of the perforated shell 1, the single-chip computer 2 turns off the belt conveyor 7, and the single-chip computer 2 turns off the belt conveyor 7. Machine 2 starts the motor 65 to drive the left rotating shaft to rotate. The left rotating shaft is driven by the belt between the pulley 63 and the belt 64, so that the corresponding feed roller 62 rotates synchronously. During the rotation of the feed roller 62, the contact friction between itself and the bottom of the packaging box is used to make the packaging box move left along the bottom wall of the punching shell 1. The belt transmission diameters of the two pulleys 63 are different, so as to ensure the belt transmission of the belt 64. After the punching of the packaging box is completed, the single-chip computer 2 controls the electro-hydraulic push rod 1 3, the electro-hydraulic push rod 2 61 and the electro-hydraulic push rod 3 53 to reset their telescopic ends. Then the single-chip computer 2 starts the automatic feeding mechanism 6 to transport the punched packaging box to the belt conveyor 7 on the left. The device can automatically load and unload the packaging box through the conveying element without manual intervention, thereby improving the efficiency of punching the packaging box.

[0028] The working principle of a punching device for packaging box processing provided by the utility model is as follows: when punching a packaging box during processing, first, the single chip microcomputer 2 starts the belt conveyor 7 from right to left to punch and transport the packaging box. When the packaging box moves to the right side of the bottom wall of the perforated shell 1, the single chip microcomputer 2 closes the belt conveyor 7, and at the same time, the single chip microcomputer 2 starts the motor 65 to drive the rotating shaft on the left side to rotate. The rotating shaft on the left side is driven by the belt between the pulley 63 and the belt 64, so that the corresponding feeding roller 62 rotates synchronously. During the rotation of the feeding roller 62, the contact friction between itself and the bottom of the packaging box is used to make the packaging box move left along the bottom wall of the perforated shell 1. The belt transmission calibers of the two pulleys 63 are different, so as to ensure the belt transmission of the belt 64. At the same time, the single chip microcomputer 2 starts the electro-hydraulic push rod 1 51 so that its telescopic end drives the corresponding preliminary limit seat 52 to move toward one end close to the center of the device, thereby preliminarily intercepting the left movement of the packaging box in the perforated shell 1. Then the single chip microcomputer 2 starts the electro-hydraulic push rod 3 53 so that its telescopic end drives The corresponding connecting seat 54 moves toward the center of the device, so that the two limiting plates 553 can clamp and fix the packaging box at the punching position longitudinally. In this process, the compression elastic force of the spring 1 552 is used to avoid the packaging box from being squeezed and deformed due to hard contact between the limiting plates 553 and the packaging box. At the same time, as the two arc-shaped limiting seats 563 move longitudinally together, the arc surface of the arc-shaped limiting seat 563 contacts the right edge of the packaging box. Through the contact pressure, the telescopic end of the telescopic column 2 561 and the spring 1 are The second 562 shrinks adaptively and cooperates with the preliminary limit seat 52 to perform horizontal punching and centering limit on the packaging box. Then the single chip computer 2 turns off the motor 65 and starts the electro-hydraulic push rod 1 3 so that its telescopic end drives the punching seat 4 to move downward, and the packaging box is punched by cooperating with the punching groove. Then the single chip computer 2 controls the electro-hydraulic push rod 1 3, the electro-hydraulic push rod 2 61 and the electro-hydraulic push rod 3 53 to reset their telescopic ends. Then the single chip computer 2 starts the automatic feeding mechanism 6 to transport the punched packaging box to the belt conveyor 7 on the left.

[0029] It is worth noting that the single chip microcomputer 2 disclosed in the above embodiment can adopt MCS-51, the electro-hydraulic push rod 1 3, the electro-hydraulic push rod 2 51 and the electro-hydraulic push rod 3 53 can all adopt DYZW integral straight micro-electro-hydraulic push rods, the motor 65 can adopt 130SZ01, and the belt conveyor 7 can adopt GTX-003 micro-electric conveyor belt conveyor. The single chip microcomputer 2 controls the operation of the electro-hydraulic push rod 1 3, the electro-hydraulic push rod 2 51, the electro-hydraulic push rod 3 53, the motor 65 and the belt conveyor 7 using methods commonly used in the prior art.
