Description

Technical Field

[0001] The utility model relates to the technical field of filter cloth edge wrapping, and particularly relates to an edge wrapping device for filter cloth production. Background Technique

[0002] Filter cloth is a filtering medium woven from natural fibers or synthetic fibers, mainly used for air filtration and removal of dust, collecting dust powder to purify air and protect the environment, and is widely used in industries such as smelters, chemical plants, sugar production, dyes, pharmaceuticals, and food.

[0003] During the production process of filter cloth, it is necessary to cut the filter cloth. In order to prevent phenomena such as thread running at the cut edge and strengthen the strength of the cut edge position, edge wrapping operations are usually carried out on the edge part of the filter cloth.

[0004] However, when carrying out the edge wrapping operation of filter cloth through sewing equipment, a lot of broken thread ends and fluff will be generated. If not processed in time, it is easy to affect the cleanliness during the edge wrapping of filter cloth. At the same time, these fluffs will float in the air and are easily inhaled by operators, affecting physical health; in addition, during the edge wrapping sewing process of filter cloth, it is necessary to pull the filter cloth with the edge wrapping. For novices, it is easy to generate deviation during the pulling process of the filter cloth, affecting the operation accuracy of edge wrapping; in addition, during the edge wrapping process of filter cloth, it is necessary to push the filter cloth forward. During the forward pushing process, the filter cloth is prone to folding and deformation in the front, which will affect the flatness of edge wrapping sewing, and thus easily lead to deviation during the edge wrapping sewing process of filter cloth.
