Description

Pearl feeding device for pearl embroidery and embroidery machine thereof
Technical Field
The invention relates to an embroidery machine, in particular to a bead belt pushing device in pearl embroidery and an embroidery machine thereof.
Background
The electric embroidery machine embroiders the flake-shaped sequins on the clothes, a plurality of plastic sequins connected together are adopted to form sequin strips, the sequin strips are sent into the sequin positioning pushing device during embroidering, and the sequins are cut one by one at the forefront end to form single sequins and embroidered on the clothes.
The existing sequin positioning and pushing device mainly comprises a positioning groove for the operation of a sequin belt, a sequin push rod is arranged above the positioning groove, the tip of the front end of the sequin push rod is intermittently inserted into a through hole in the sequin and forwards pushes a sequin for a distance under the action of a power device, the sequin push rod circularly reciprocates, and one sequin is sent out in each period, so that continuous feeding and feeding of the sequin are realized.
CN1673436a discloses a sequin embroidery tablet positioning and feeding device, which comprises a linear reciprocating motion power mechanism composed of a shell, a push rod, a coil, a lower iron plate, magnetic steel, a guide post, a circuit board and the like; the tablet positioning mechanism consists of a bracket, a support, a spring plate, a feeding hook, a spring plate and the like; the push rod of the power mechanism is connected with a stop block of a feeding hook of the tablet positioning mechanism, a feeding hook frame, a torsion spring for resetting and the like to drive the bead positioned by the tablet positioning mechanism to intermittently feed and feed in fixed length. Similar sequin positioning and pushing devices also include CN1858325A, CN1858326a, CN1865572a, etc.
For non-lamellar beads, the existing equipment is to lead the silk thread to pass through the through holes in the beads to form bead strings, guide the bead strings into a positioning and feeding device, separate the beads one by clamping, pincers and the like and send the beads to corresponding positions of an embroidery needle, and the pincers are loosened to embroider when the embroidery needle falls down to pass through the through holes of the beads. Publications such as CN103757837a, CN103866502a, etc. for this approach. The control difficulty is high, and the pearl embroidery efficiency is low.
CN102551245a provides a bead strip formed by repeatedly connecting units formed by connecting plastic beads with bead holes and connecting bodies, the direction of each bead hole is perpendicular to the direction of the bead strip, and the connecting bodies are positioned in the middle of the side surfaces of the plastic beads. The directions of the bead holes of the bead belts disclosed in CN101766347A, CN202112369U, CN202081269U and the like are perpendicular to the bead belt direction. The bead belt can be used for supplying the beads by using the existing bead positioning pushing device, but because the beads are in a three-dimensional shape, the positioning of the bead belt is difficult to stabilize, when the tip of the front end of a bead push rod is intermittently inserted into a through hole in the beads, the push rod is occasionally not aligned with the through hole or the through hole of the beads is not aligned with an embroidery needle after the beads are pushed out, so that the beads are failed to push, empty needles appear, and embroidery fabrics become waste products.
Disclosure of Invention
The invention aims to provide a bead feeding device for a bead belt embroidery bead, which can avoid the occurrence of failed bead pushing or empty needle caused by misalignment of a push rod with a through hole or misalignment of a through hole of a bead with an embroidery needle after pushing out the bead.
The invention also provides an embroidery machine with the bead feeding device.
The bead feeding device for the bead embroidery comprises a bead guide rail for passing a bead belt, wherein the bead guide rail is provided with a bead belt fork rod, the front end of the bead belt fork rod is in contact with the bead in an inclined mode, the front end of the bead belt fork rod is provided with a concave fork opening matched with the outline of the bead, the bead belt fork rod is connected with an intermittent propelling mechanism, the rear part of the bead belt fork rod is provided with a spring for enabling the front end of the bead belt fork rod to press the bead belt, the bead belt guide rail is provided with an elastic pressing sheet, and the front end of the elastic pressing sheet is provided with a buckle for preventing the bead belt from retreating.
The front end of the bead belt push rod is positioned at the 2 nd to 5 th bead positions at the forefront end of the bead belt.
And an embroidery machine provided with the bead feeding device.
The invention pushes the bead belt from the side direction through the concave arc fork opening, and the concave arc fork opening has higher fault tolerance capability, can prevent the bead belt from twisting and the bead from rotating, and can improve the success rate of bead feeding and needle threading each time.

Fig. 2 is a perspective view of one embodiment of the present invention.
Fig. 3 is a top view of the bead yoke.
Fig. 4 is a cross-sectional view of the push rod and bead belt mating.
Fig. 5 is a schematic illustration of the engagement of the push rod and bead.
Detailed Description
As shown in fig. 1, the bead strip 1 used in the present invention is formed by connecting beads 101 having a three-dimensional shape including, but not limited to, a spherical shape, an ellipsoidal shape, a rod shape, or a rectangular parallelepiped shape, through holes 103 for threading yarns are provided in each bead, and the through holes 103 are perpendicular to the direction of the bead strip 1.
