Description

Technical Field

[0001] The utility model relates to the technical field of bag breaking and unloading of powdery materials, in particular to an automatic bag breaking device. Background Art

[0002] With the rapid development of the market economy, people's living standards are getting higher and higher. Many jobs with high labor intensity and harsh environment will cause harm to the human body. For example, in the preparation of some chemical products, powders are often packaged in bags. For example, in silica gel production equipment, the powders need to be broken into bags and added to the material tank. In the past, many companies manually carried the bags to the equipment, then cut the bags with blades, and shook the powders into the hopper. This kind of work is labor-intensive and has a harsh dust environment. Working in this environment for a long time can easily cause damage to the health of workers.

[0003] At present, the automatic bag opening device on the market generally conveys the packaging bag to a porous rotating drum through a belt assembly, uses a high-speed rotating blade to cut the packaging bag, and discharges the powder in the bag into a hopper. However, this method has two disadvantages: first, the debris of the packaging bag will be mixed into the powder, which is easy to contaminate the powder; second, after the packaging bag is cut and discharged, there will be a lot of residual material that does not enter the hopper, causing waste, causing secondary pollution when the empty bag is recycled, and at the same time, the open broken bag will also cause dust pollution to the surrounding environment, which is easy to endanger the health of the operator.

[0004] The utility model is made based on the above situation. Utility Model Content
