Device for converting outwards-folded ear cords into inwards-folded ear cords of mask machine

Abstract

The invention discloses a device for converting outwards-folded ear cords into inwards-folded ear cords of a mask machine, and relates to the technical field of mask processing equipment. The device comprises an ear cord folding mechanism used for converting the outwards-folded ear cords into the inwards-folded ear cords of a mask, the ear cord folding mechanism comprises a fixing cover and a linkage block, a connecting plate is movably arranged in the fixing cover, a first rack is arranged at the top of the connecting plate, an ear cord folding plate is arranged at one end of the connecting plate, a flow guide plate is arranged at one side of the fixing cover, and a fixing rod is fixedly arranged in the fixing cover. By arranging the ear cord folding mechanism and a conveying mechanism, an air cylinder is started to drive a hot melting pressing block to descend, meanwhile, a second rack abuts against a first gear along with descending of a driving block, the ear cord folding plate moves synchronously, and therefore ear cord folding and shaping operation is conducted on the mask, the ear cord folding procedure and the positioning procedure of the device are driven by the same power source, the use energy consumption is reduced, the processing cost is reduced, economic benefits are met, and wide application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of mask processing equipment, in particular to a device for converting outer-folded earbands into inner-folded earbands for a mask machine. Background technique [0002] The mask machine is a multi-layer non-woven fabric through hot pressing, folding forming, ultrasonic welding, waste removal, ear strap nose bridge welding and other processes to produce various masks with certain filtering performance. The mask production equipment is not a single machine, it It requires the cooperation of multiple machines to complete various processes. [0003] At present, most of the existing ear folding lines for masks require multiple power sources to complete, with complex structures and high manufacturing costs. At the same time, one ear folding line can only process masks of the same specification, and cannot fold ears of masks of different specifications. , it is necessary to re-open a folded ear line body, which g...

Problems solved by technology

[0003] At present, most of the existing ear folding lines for masks require multiple power sources to complete, with complex structures and high manufacturing costs. At the same time, one ear folding line can only process masks of the same specification, and cannot fold ears of masks of different specifications. , it is necessary to re-open a folded ear line body, which greatly increases the processing cost and takes up a large working space. Generally, the front and back sides are not distinguished during mask processing, and only need to be screened during later packaging, resulting in the packaging process. The difficulty of work is greatly increased, which seriously affects the packing efficiency and leads to the accumulation of materials, which can no longer meet the needs of use
