Three-gold embroidery side-by-side piece feeding mechanism

Abstract

The invention discloses a three gold foil embroidery side-by-side foil conveying mechanism. The mechanism comprises a foil conveying inversion mechanism which can move in the directions of X and Y axes, a foil conveying engine base, three foil conveying foot pushing devices, a foil conveying slot with three side-by -side positions, a foil changing device and a foil cutting device; the upper ends of pushing arms of the three foil conveying foot pushing devices are connected in series and hinged with the same dead axle; three tension springs and three pressure springs are used for resetting and tabletting; push-and-pull hooks are extended out of the lower part of pushing arms in parallel; the foil changing device comprises a motor, a rotation axis and a foil changing clutch which is coupled with a transmission shaft and alternately drives the three foil conveying foot pushing devices to act; the foil changing clutch comprises a connection sleeve, a clutch wheel, and a shifting fork which stirs the clutch wheel to slide; and the edge of the clutch wheel is provided with a stirring hammer which is positioned in a hook groove of the push-and-pull hook and stirs each pushing arm to act along with the rotation of the motor. The three gold foil embroidery side-by-side foil conveying mechanism has the advantages that: gold foils are not easy to block, the efficiency is high, the three gold foil embroidery in different forms and of various specifications can be realized, and the number of used motors is small.

Description

technical field [0001] The invention relates to a piece changing and feeding device of a sequin embroidery machine, in particular to a three-sequin embroidery side-by-side feeding mechanism capable of outputting sequins of three specifications. Background technique [0002] In the prior art, the three-sequin embroidery feeding mechanism can realize the transportation of three kinds of specifications of sequins for embroidery. The structure mainly includes a piece-feeding machine base, three piece-feeding push-foot devices installed on the piece-feeding machine base, and three The film feeding slot at the film feeding position, as well as the film changing device and the slicing device, the film feeding push foot device includes a push arm and a push foot hinged thereto. There are Chinese utility model patents "three-gold embroidery feeding device", the patent number is CN200820201297.8; "three-gold embroidery automatic piece feeding device", the patent number is CN2009200504...

Problems solved by technology

There are Chinese utility model patents "three-gold embroidery feeding device", the patent number is CN200820201297.8; "three-gold embroidery automatic piece feeding device", the patent number is CN200920050469.0; No. CN200920050468.6, these patents realize the conveying of three different specifications of sequins for embroidery, but their common feature is that the three feeding slots are stacked in three layers, and the order is from large-sized sequins to small-sized sequins It is stacked from the bottom to the top, while the piece feeding and pushing device is arranged from the back to the front. The main disadvantage of this structure is that the bottom piece feeding groove is long, and the gold piece is easy to block, and it is troublesome to clean up after the blockage, which affects Work efficiency, and sometimes the center of the sequins of three specifications is moved to the position under the needle tip of the embroidery needle is not accurate enough, resulting in quality problems in embroidery
