Description

Technical Field

[0002] The dust bag is the heart of the bag dust collector. It is generally called a filter dust bag, a dust filter bag, a dust collection bag, a dust accumulation bag, a dust bag, a dust collector bag, etc. The dust bag is a key part of the operation of the bag dust collector. According to the filtering method, it is mainly divided into two types: internal filtering and external filtering. Internal filtering dust bag: After the dust gas is filtered through the inner surface of the filter bag, the dust is blocked on the inner surface of the filter bag. This filtering method is called internal filtering. External filtering dust collector bag: After the dust-containing gas is filtered through the outer surface of the filter bag, the dust is blocked on the outer surface of the filter bag. This filtering method is called external filtering.

[0003] Dust bags need to be cut during the production process. The existing dust bag cutting device has a poor cutting effect, which causes the warp and weft lines on the cut dust bags to become loose. Therefore, we propose a shearing device for the production of dust bags. Utility Model Content
