Thread trimming structure for embroidery machine

Technical Field

The utility model belongs to the technical field of embroidery machines, and particularly relates to a thread cutting structure for an embroidery machine.

Background

The cap embroidery and the garment embroidery are to embroider the finished cap and garment with the embroidery machine to make the finished cap and garment have the needed pattern. The shuttle box body is an essential component of the embroidery machine, and the common shuttle box body cannot be directly used for embroidering finished clothing due to structural limitation, namely, the embroidery machine adopting the common shuttle box body structure cannot perform cap embroidery and ready-made clothing embroidery.

To this end, the patent with application number CN201120107434.3 discloses a rotating shuttle box for a multi-machine-head arc-shaped table-board garment embroidery machine, which comprises a base body and a hanging neck, wherein a rotating shuttle assembly is installed at the front end of the hanging neck, the rear end of the hanging neck is the base body, a rotating shuttle shaft in the rotating shuttle assembly penetrates through the front end to the rear end of the hanging neck, the rear end of the rotating shuttle shaft is in transmission connection with a main transmission shaft which is rotationally arranged in the base body, a fixed shear and a rotary shear of a thread trimmer assembly are arranged on the rotating shuttle assembly, the fixed shear is fixed on an installation base of the rotating shuttle assembly, the rotary shear is hinged with the installation base of the rotating shuttle assembly, one rotating end of the rotary shear is hinged with the front end of a connecting rod, the rear end of the connecting rod is hinged with an eccentric wheel, and the eccentric wheel is rotationally arranged on the base body and in transmission connection with a thread trimmer driving mechanism. The success rate of thread cutting of the rotating shuttle box with the structure is lower, and the thread can easily slide off from the rotating scissors when the rotating scissors rotate, so that the thread cutting is unsuccessful.

In order to improve the success rate of thread cutting, a thread-locking mechanism is usually added to a rotating shuttle box in the prior art, for example, patent application number CN201810142641.9 discloses an embroidery machine, which comprises an embroidery machine head, a shuttle box, a thread-locking device and a thread-cutting device, and the thread-cutting device is assisted by the thread-locking device to complete thread-cutting action. However, the setting of the thread buckling device can enable thread cutting operation to have two actions of thread buckling and thread cutting, and the thread cutting method is high in control difficulty and cost, and the thread cutting success rate is not very high.
