Description
Technical Field
The invention relates to the field of embroidery machines, in particular to a rope clamping and rope shearing integrated device for an embroidery machine.
Background
The current embroidery machine needs to cut off embroidery ropes and embroidery threads after the embroidery is completed, so that the embroidery ropes and the embroidery threads are separated from the cloth. The traditional embroidery ropes and embroidery threads are cut off manually, and because the machine heads on the embroidery machine are many, the manual cutting of the embroidery ropes and the embroidery threads on the machine heads is not only large in workload, but also easy to cause the problems of wrong cutting or missed cutting.
In order to solve the above-mentioned deficiency, some embroidery machine heads at present are provided with a rope shearing device and an embroidery rope and embroidery thread clamping and fixing device, wherein the rope shearing device is used for shearing the embroidery rope and the embroidery thread, and the embroidery rope and the embroidery thread clamping device are used for clamping and fixing the embroidery rope and the embroidery thread before shearing the embroidery rope and the embroidery thread so as to ensure smooth shearing of the embroidery rope and the embroidery thread. Because the outer diameters of the embroidery ropes and the embroidery threads are large in difference (the outer diameters of the embroidery ropes are far larger than the embroidery threads), the embroidery ropes and the embroidery threads are clamped by the same clamping device, and the embroidery threads cannot be clamped and fixed often; therefore, the current embroidery rope and embroidery thread clamping device generally comprises a rope clamping device for clamping and fixing the embroidery rope and a thread clamping device for clamping and fixing the embroidery thread, and the rope clamping device and the thread clamping device respectively clamp the embroidery rope and the embroidery thread by adopting a driving mechanism and a clamping mechanism, so that the cost is increased, the embroidery rope and the embroidery thread clamping device have larger volumes and occupy larger space, the machine head space of an original very compact embroidery machine becomes more crowded, and particularly when the machine head is additionally arranged on the original embroidery machine, the machine head is compact in structure, and the embroidery rope and the embroidery thread clamping device with larger volumes are not installed in enough space, so that the problem that the embroidery rope and the embroidery thread cannot be automatically sheared is caused.

The thread clamping mechanism 2 comprises a thread clamping tension spring 2.1 for clamping the embroidery thread 11. One end of the wire clamping tension spring is connected with one clamping arm, and the other end of the wire clamping tension spring is connected with the other clamping arm. When the rope clamping opening is closed, the loops of the rope clamping tension spring are tightly clamped together to clamp the embroidery thread.

The cylinder body of the driving cylinder is hinged with the mounting bracket, and the piston rod of the driving cylinder is hinged with the lifting bracket. Therefore, in the process of driving the mounting seat to move by the driving cylinder, the characteristics of the parallel four-bar mechanism can be utilized, so that the mounting seat and the rope clamping device and the rope cutting device on the mounting seat move along an arc track, and meanwhile, the mounting seat and the rope clamping device and the rope cutting device on the mounting seat do not rotate in the moving process.
Further, the mounting bracket 6 comprises a transverse adjusting bracket 6.1, a vertical adjusting bracket 6.2 and a vertical bracket 6.3 connected with the vertical adjusting bracket through bolts.
