Technical Field

[0001] This utility model relates to the field of paper box opening technology, specifically a paper box opening device. Background Technology

[0002] With the rapid development of the packaging industry, cardboard boxes are increasingly used in food, pharmaceuticals, and other fields. Their functional requirements have expanded from basic protection to convenience and aesthetics, placing higher demands on the precision, shape, and mass production efficiency of the perforation process. At the same time, under the trend of environmental protection and lightweighting, new environmentally friendly cardboard is becoming more and more popular, which also poses challenges to the waste disposal efficiency of perforation equipment.

[0003] The patent publication number "CN219706228U" discloses a "packaging cardboard box punching device", which includes a workbench, a gantry frame mounted on the workbench, a punching cylinder mounted on the gantry frame, a slider mounted on the output shaft end of the punching cylinder, the slider mounted on a vertical guide rail, and the vertical guide rail mounted on the gantry frame, a guide rod mounted on the slider, and a punching tool mounted on the end of the guide rod, the punching tool including a cylindrical blade body, a spring plate disposed inside the cylindrical blade body, a punching mold disposed below the punching tool, and a mounting through hole for mounting the punching mold being provided on the workbench.

[0004] The aforementioned patent addresses the issues of "sticking" to the blade or adhesion within the holes, thus facilitating the punching of packaging cartons. Furthermore, the cylindrical blade body and spring plate work together to guide the waste cardboard, making its landing point controllable and easier to collect. However, the device uses a material collection tube below the through-hole to collect punching waste. If this tube is not cleaned promptly after prolonged operation, waste may accumulate and push against the blade, affecting punching smoothness and potentially causing equipment malfunction. Additionally, the device has different requirements when punching cardboard of varying thicknesses, potentially leading to poor applicability.

[0005] Therefore, this utility model provides a packaging paper box opening device to solve the above problems. Utility Model Content

The support assembly 1 includes a workbench 101, and the four corners of a mounting plate 102 are fixedly connected to the inner surface of the workbench 101. A cleaning assembly 2 is provided above the mounting plate 102, and the cleaning assembly 2 includes a support platform 201. A blower 202 base is fixedly connected to the upper surface of the support platform 201. One end of a connecting hose 203 is fixedly connected to the air outlet of the blower 202, and the other end of the connecting hose 203 is fixedly connected to an air outlet chamber 204 interface. The inner surface of the support platform 201 is fixedly connected to the side surface of the mounting plate 102. A square hole 103 is opened at the center of the upper surface of the workbench 101. A square table board 108 is movably connected to the inner wall of the square hole 103. A lifting platform 109 output end is fixedly connected to the center of the lower surface of the square table board 108, and the end of the lifting platform 109 is fixedly connected to the center of the upper surface of the mounting plate 102.

[0031] In this embodiment, when the cardboard box punching operation is started, the lifting platform 109, according to the cardboard box thickness requirements, drives the output end to extend and retract via the hydraulic cylinder 106, causing the square table 108 to move up and down along the inner wall of the square hole 103, adjusting the cardboard box to a suitable processing height; during the punching process, the blower 202 is powered on and runs, and the generated airflow is transported to the air outlet chamber 204 via the connecting hose 203, and blown out directionally from the interface of the air outlet chamber 204 to sweep away the paper scraps and waste generated during punching.

[0032] Reference Figures 1 to 4 In one aspect of this embodiment, the inner surfaces of support frames 104 are fixedly connected to both sides of the top of the workbench 101, and mounting holes 105 are provided on the upper surface of the support frames 104.
