Description

Novel hopper switch mechanism of pearl embroidery device

Technical Field

The utility model relates to a hopper switching mechanism, in particular to a novel hopper switching mechanism of a pearl embroidery device.

Background

The computerized embroidery equipment is one kind of computerized embroidery technology. When embroidery is made by a computerized embroidery machine, beads with various colors are interspersed on the embroidery at any time under the condition of no shutdown according to the pattern or product requirements. Pearl embroidery mainly comprises round glass beads, bubble beads, long tubular beads and the like.

The beads in the lower cup cannot be stored too much in the existing pearl embroidery processing process, and the beads can pop up the lower cup due to the influence of the resistance of the lower cup and the beads on the bead threading steel wire, if multiple groups of color beads are embroidered simultaneously, color cross is easily caused, and the embroidery is defective or rejected. However, after the cup cover is added, the feeding of the cup is inconvenient, so that the feeding cup needs to be added, but how to control the dropping speed of the beads in the feeding cup by the feeding cup, and the number of the beads in the cup is controlled according to the actual embroidery bead requirement, so that a great technical problem of the bead embroidery device is solved.

Currently, there are two general approaches to solve this problem in the market. The first scheme is as follows: for example, CN 202021799369-an embroidery bead feeding control mechanism and CN 202021799368-an embroidery bead feeding device for an embroidery machine, the principle that the magnetic poles of magnets repel each other is adopted to open and close the valve, but the valve is limited by the distance between the two magnets, and meanwhile, the opening is not easy to adjust. In another scheme, the bead discharging is controlled by the size of the bead outlet of the different hoppers and the stacking direction of the beads in the bead outlet of the hopper and the lower cup, namely, more beads are stacked at the bead outlet of the hopper, and the bead outlet is less in bead discharging amount; otherwise, the amount of the beads is more, and therefore, a novel hopper switching mechanism of the pearl embroidery device is provided.
