Description
Technical Field
The invention relates to a pearl embroidery machine.
Background
The pearl embroidery is embroidery formed by threading pearls, glass beads and jewel beads by using needles and forming patterns on textiles. The pearl embroidery has the artistic characteristics of brilliant pearly luster, gorgeous and colorful colors, clear level and strong stereoscopic impression.
The bead embroidery principle is that firstly an embroidery needle downwards penetrates embroidery threads through a cloth cover and then upwards penetrates through the cloth cover, and then the embroidery needle downwards runs through beads and embroiders the beads on the cloth cover. In the process, before an embroidery needle passes through the beads, the beads need to be fed in place, the existing computer bead embroidery machine generally adopts a clamping mode to clamp and feed the beads, a certain threading gap is needed even if the clamping notches of the two clamping heads are in a state of clamping the beads, and when the embroidery thread penetrates into the beads and embroiders downwards, the embroidery thread passes through the threading gap and is separated from the clamping heads, so that the beads are further embroidered on the cloth surface. However, when the embroidery thread is moved upward with the embroidery needle at high speed, the embroidery thread is close to the chuck because the embroidery thread is already in the bead feeding state, and even in the clamping state, the clamping force of the chuck on the beads is not large (the beads are crushed due to too large clamping force), so that the embroidery thread moving at high speed easily enters the clamping groove through the gap and touches the beads in the clamping groove, and the beads are scattered.
The patent applications that have been published so far also suffer from the above-mentioned problems. For example, the chinese utility model patent application with publication number 108560162a discloses a single-color bead feeding device for bead embroidery, wherein a driving motor is installed at one side of a frame; the driving motor comprises a motor shaft; the driving crank is arranged on the motor shaft and is driven by the motor shaft; one end of the connecting rod is connected to the driving crank, and the other end of the connecting rod is connected to the bead feeding swing rod; the ball feeding swing rod is driven by a connecting rod, and one end of the ball feeding swing rod is pivoted on the rack; the other end of the ball feeding swing rod is provided with a groove, and the groove is clamped on the elastic ball clamping plate and can drive the elastic ball clamping plate; the guide chute cover plate is arranged above the elastic bead clamping plate, and the base is arranged below the elastic bead clamping plate; the base is provided with a sliding chute, and the elastic bead clamping plate can move back and forth along the sliding chute; the first group of roller devices and the second group of roller devices are positioned on two sides of the sliding chute, are arranged oppositely and are respectively arranged on the base; the ball guide seat is fixed on the guide sliding groove cover plate and is positioned above the elastic ball clamping plate. For example, the chinese utility model patent with publication number 207759677U discloses a bead feeding device of a bead embroidery machine, which comprises a supporting seat, a bead feeding slider, a clamping assembly, an upper pressing plate, a clamping mechanism and a translation mechanism capable of driving the bead feeding slider to move back and forth; the supporting seat is provided with a guide sliding chute and a clamping groove, and the rear end of the clamping groove is connected with the front end of the guide sliding chute; the ball feeding slide block is positioned in the guide chute and is connected with the power output end of the translation mechanism; the clamping assembly comprises a tongue part and two elastic clamping arms, each elastic clamping arm comprises a connecting part and a clamping part, the rear end of each connecting part is connected with the ball feeding sliding block, and the front end of each connecting part is connected with the clamping part; the two connecting parts are respectively positioned at two sides of the tongue part, and the clamping part is positioned in front of the tongue part; the arc grooves of the two clamping parts form a bead clamping jaw; the clamping mechanism comprises two clamping blocks and two elastic assemblies, the two clamping blocks are respectively installed on the side wall of the clamping groove through the elastic assemblies, and the inner side faces of the clamping blocks are gradually inclined inwards from back to front.
