Description

Thread-buckling device of small-head-distance embroidery machine

Technical Field

The utility model belongs to the technical field of the embroidery machine, especially, relate to a small-head-distance embroidery machine thread take-up device.

Background

The existing embroidery machine structure comprises an embroidery machine head, a thread buckling device and a thread cutting device. Each rotating shuttle on the existing embroidery machine is provided with a thread-fastening device and a thread-cutting device independently, and each thread-fastening device is provided with a driver independently, so that the required installation space is larger. For the embroidery machine with large head distance, the installation space is relatively abundant, but for the embroidery machine with small head distance, the installation difficulty is higher, and the installation space for the thread fastening device is very limited. Even if it is possible to install, the problem of replacing the bobbin thread needs to be considered. Generally, the bobbin thread is replaced once in half an hour, when the bobbin thread is replaced, an operator or a manipulator is required to firstly translate the bobbin case outwards and downwards pull out from the rotating shuttle, and then the bobbin case is put back to the rotating shuttle according to the original direction after the bobbin thread is replaced. This replacement process requires the operator or robot operating space to be reserved, while also taking into account the interference problems that exist during the path replacement.

The utility model patent CN207958716U discloses an embroidery machine thread take-up device to specifically disclose thread take-up device include movable mounting and be used for detaining the thread take-up piece, the drive pivot of rotation installation on the shuttle case of rotating shuttle at the shuttle case, be connected with two at least thread take-up pieces in the drive pivot simultaneously, the drive pivot is connected with the connecting rod, the connecting rod is connected with first driver, the drive pivot drives two at least thread take-up piece functions simultaneously under the drive of first driver. The device connects a plurality of wire buckling pieces to a driving rotating shaft at the same time, and the driving rotating shaft is driven by a driver, so that the installation space can be saved to a certain extent. The thread buckling mode of the thread buckling device is that the thread buckling fork swing rod arranged on the side surface of the rotating shuttle swings to buckle the upper thread, and the thread buckling device inclines from bottom to top to realize thread buckling and then inclines from top to bottom to realize thread loosening. The thread take-up and release directions interfere somewhat with the bobbin thread replacement path. Even if the thread-fastening and thread-releasing directions are changed into linear translation on the same horizontal plane, the problem that the bobbin case cannot be taken out also exists. In addition, the driving rotating shaft of the thread buckling device is arranged in front of the shuttle race transversely and below the rotating shuttle, a vertically arranged fixed block is arranged between the thread buckling piece and the driving rotating shaft, the fixed block and the driving rotating shaft occupy a large amount of space, and the interference problem exists no matter manual operation or mechanical hand operation. Obviously, the thread buckling device cannot meet the requirement of frequent bottom thread replacement from the industrial application perspective, and the industrial applicability is poor. In addition, the driving rotating shaft of the thread fastening device needs to be connected with at least two thread fastening pieces, so that the thread fastening device cannot be integrated into a whole independent component and cannot be independently installed on and removed from the embroidery machine.
