Technical Field

[0001] The present invention relates to the technical field of mechanical manufacturing, in particular to a woven bag clamping device. Background Art

[0002] After processing, materials need to be packaged before they can be stored or shipped. Currently, there are two main types of packaging: vacuum packaging in plastic film bags and sewing in plastic woven bags.
