Description

Technical Field

[0001] The present invention relates to the technical field of package unpacking machines, and in particular to an automatic package unpacking machine and an unpacking method thereof. Background Art

[0002] The automatic unpacking machine is a highly efficient packaging processing equipment, which is widely used in food, chemical, logistics and other industries. In modern production and warehousing environments, the automatic unpacking machine can realize the rapid disassembly of different packaging forms through the intelligent operating system, effectively improving the working efficiency. The efficient operation of the automatic unpacking machine can also be linked with other production equipment to form an automated production line and realize intelligent management of the entire process. With the continuous advancement of technology, these devices are also constantly upgraded and have higher flexibility and adaptability to meet the needs of different customers. The application of automatic unpacking machines has significantly improved production efficiency, promoted the modernization process of enterprises, and become an indispensable and important equipment in modern industry.

[0003] After searching, the invention patent of Chinese patent number CN117446307A discloses a new type of fully automatic unpacking machine, including a frame, a feeding port is provided on one side of the frame, an unpacking station is also provided on the frame, one side of the unpacking station is a feeding end, and the other side is a discharging end, the discharging end is rotatably matched with the frame, the feeding end is connected to the frame through a telescopic cylinder 1, a horizontal cutting mechanism 1 is provided in the middle part of the unpacking station, a vertical cutting mechanism 2 is provided at the discharging end of the unpacking station, and a baffle is also provided on the unpacking station, and the baffle is rotatably matched with the unpacking station. Compared with the prior art, the invention patent of Chinese patent number CN117446307A solves the problem that a large amount of dust will appear in the unpacking process of the unpacking machine of the prior art, and the packaging bags after unpacking cannot be automatically recycled and need to be recycled manually, so the factory environment of the existing unpacking link is often very messy and dust is also a very large problem.

[0004] However, in actual use of the above device, after the packaging bag is cut by the cutter, the material will automatically flow down from the rupture, thereby separating the packaging and the material. However, the material is often retained in the four corners of the bag, resulting in insufficient separation and waste. Moreover, when the material is granular, the falling material will be collected after passing through the filter screen, but the granular material can easily get stuck in the filter holes in the filter screen, which reduces the filtering effect of the filter screen. Therefore, an automatic unpacking machine and an unpacking method thereof are proposed. Summary of the invention
