Description

Technical Field

[0001] The utility model belongs to the technical field of unpacking equipment, and particularly relates to a dust removal device for a sterile unpacking machine and the sterile unpacking machine. Background Art

[0002] Bag unpacking machines are widely used in industries such as chemical, pharmaceutical, food, and building materials that need to handle bagged powdered materials.

[0003] Among them, many application scenarios require the unpacking machine to reach the sterile level, that is, it can be rinsed clean inside the unpacking machine and achieve a sterilization effect by spraying hot water or high-temperature steam.

[0004] Most existing bagging machines use a conveyor mechanism within a housing to transport materials. The conveyor mechanism is equipped with a bagging cutter, and a discharge port is located at the bottom of the housing. During operation, the bagging cutter on the upper side opens the bag, and the bag continues to be transported forward, allowing the powdered material in the bag to fall directly into the discharge port at the bottom of the conveyor mechanism.

[0005] Powder materials will generate some dust when unpacking, so unpacking equipment is usually equipped with a dust removal device. The dust removal device on the existing unpacking machine is mostly a bag-type dust removal device and is usually installed on the top of the unpacking machine.

[0006] If the dust collector is installed on top of the unpacking machine, the dust will have to travel a long distance before being absorbed by the dust collector. During this process, the dust is likely to spread further. In addition, the bag-type dust collector is not easy to clean by spraying. Utility Model Content
