Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper box production, in particular to a punching device used for corrugated paper box production. Background Art

[0002] Corrugated cardboard is die-cut, creased, and either stapled or glued together to create corrugated boxes. Corrugated boxes, including calcium-plastic corrugated boxes, are the most widely used packaging product, consistently leading the way in terms of volume. For over half a century, thanks to their superior performance and processability, corrugated boxes have gradually replaced wooden boxes and other transport containers, becoming the mainstay of transportation packaging. In addition to protecting goods and facilitating storage and transportation, corrugated boxes also enhance product aesthetics and promote their value. They are environmentally friendly and facilitate both loading and unloading. A corrugated box punching device is a device used to create holes in specific locations during the corrugated box production process. With the development of society, punching devices are increasingly used when corrugated boxes require additional perforations.

[0003] Existing equipment, such as CN115847518B, relates to a bidirectional punching device for corrugated cardboard boxes, comprising a base plate, a support mechanism, and a punching mechanism. The support mechanism is disposed on the base plate and includes two side plates and two support columns. Sliders are fixedly connected to the bottoms of the two side plates, and the surface of the base plate is provided with two slide grooves corresponding to the two side plates. The device relates to the field of corrugated paper processing. This bidirectional punching device for corrugated cardboard boxes is designed with a special punching structure to address the high failure rate and creases that are common in corrugated cardboard punching devices. This effectively addresses the issues of conventional corrugated cardboard punching devices, such as a flat punch tip and high impact force, which easily leave creases on the cardboard surface when punching, affecting subsequent cardboard processing. Furthermore, the device is difficult to punch multiple holes simultaneously, requiring frequent cardboard adjustments and resulting in poor processing efficiency.

[0004] When a worker needs to punch a corrugated cardboard box, the worker places the corrugated cardboard box on a punching device so that the punching device can punch the corrugated cardboard box. However, during the use of the punching device, the worker needs to manually remove the punched waste from the machine, which requires the worker to repeat the unloading action, thereby increasing the worker's workload.
