Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging equipment, and particularly relates to an exhaust device and a packaging machine assembly. Background Art
[0002] In traditional packaging machines, no exhaust device is provided. During the packaging process of powder materials, a large amount of gas is carried by the materials and filled into the packaging bags, resulting in a large amount of gas being sealed into the packaging bags when sealing the bags, causing the packaging bags to bulge. This affects the rated capacity and appearance beauty of the packaging bags. The bulging packaging bags are prone to tipping, affecting storage and transportation, and are also likely to cause material leakage, affecting the health of operators and causing material losses to enterprises.
[0003] In the prior art, the problem of excessive gas in the packaging bags is usually solved by setting an exhaust device. However, the existing exhaust devices cannot effectively separate gas from the materials. When recovering the powder materials, the gas may be blown back into the packaging bags again, resulting in a reduction in the exhaust effect. If the packaging channel is closed when recovering the powder materials, this problem can be solved, but it will also lead to a reduction in the packaging speed. In addition, in the prior art, the exhaust device is also set in the external environment, but the powder materials recovered in this way are easily polluted by the external environment, and the recovered powder materials are difficult to recycle.
