Ear band feeding device

Abstract

The invention discloses an ear band feeding device, which comprises an ear band bending device, a connecting mechanism, an ear band conveying device and a control system. The connecting mechanism comprises a connecting block, a first bearing follower and a second bearing follower; the connecting block is connected with the ear band bending device; the first bearing follower and the second bearingfollower are respectively connected with the connecting block; the ear band conveying device comprises a power device, a mounting plate, a connecting rod and a limiting guide mechanism for limiting rotation of the ear band bending device; a curved groove is formed in the mounting plate; a first sliding groove is formed in the connecting rod; the first bearing follower is connected with the curvedgroove in a sliding manner; the second bearing follower is connected with the first sliding groove in the sliding manner; and a power device is connected with the connecting rod and used for driving the connecting rod to rotate so that the ear band bending device can horizontally move along the track of the curve groove. According to the technical scheme, movement is stable, the feeding speed is high, the positioning precision is high, and the production efficiency of a three-dimensional mask is greatly improved.

Description

technical field [0001] The invention relates to the field of mask machines, in particular to an earband feeding device. Background technique [0002] A mask is a sanitary product made of fabric, melt-blown cloth, non-woven fabric and other materials to filter the air entering the mouth and nose. The three-dimensional mask adopts a three-dimensional structure design that matches the shape of the face, and the mask forms a cup-shaped structure after unfolding. [0003] The ear loops of the three-dimensional masks need to be bent and then welded. The production efficiency of the three-dimensional masks is generally related to the feeding speed of the ear loops. The feeding speed of the existing earband feeding device is relatively slow, and the movement of the feeding process is not stable, resulting in inaccurate positioning of the earband feeding material, which is likely to cause inconsistent welding positions of the earbands, which in turn leads to low production efficienc...
