Preferably, the lower end of the vertical rod is provided with a cutter.

Preferably, the driving device is fixedly installed on a driving device fixing bracket of the frame, and the driving device is transversely arranged at the rear end of the frame of the buttonholing machine.

Preferably, the driving device is disposed perpendicular to the buttonholing machine body.

Preferably, the driving device realizes the cloth cutting action according to one circle of operation.

Preferably, the drive means operates in half a turn to effect the above-described cutting action.

Preferably, the driving means preferably uses a servo motor or a stepping motor.

Compared with the prior art, the buttonholing machine has the beneficial effects that: the buttonhole maker of the application utilizes the cam direct action vertical rod installed by the driving device to quickly cut cloth at the first time, effectively solves the problem that the existing buttonhole maker is high in manufacturing cost, simultaneously realizes the purpose of efficiently cutting the cloth, and improves sewing quality. The driving device of the application preferably uses a servo motor or a stepping motor to control the intelligent control level of the electric control device of the buttonholing machine.

FIG. 1 is a schematic view of a keyhole machine hole cutter mechanism according to the present application;

reference numerals: the device comprises a driving device 1, a cam 2, a restoring surface 21, a working surface 22, a highest point 221, a vertical rod 3, a spring 4, a cutter 5, a push plate 6, a machine body 7 and a driving device fixing support 71.

Detailed Description

The following detailed description of the preferred embodiments of the present application, taken in conjunction with the accompanying fig. 1, is provided to enable those skilled in the art to more readily understand the advantages and features of the present application, and is provided for the purpose of clearly and unequivocally defining the scope of the present application, which is provided by way of illustration only and is not intended to be limiting of the present invention.

As shown in fig. 1, the present application provides a hole opening cutter mechanism of a buttonholing machine, which aims to realize the action of a hole opening cutter with a fast cloth cutting reaction speed by using a driving device 1 of the buttonholing machine, improve the sewing quality of the buttonholing machine and reduce the manufacturing difficulty.

Buttonholing machine trompil cutter mechanism has drive arrangement 1, pole setting 3, spring 4 and cutter 5, installs cam 2 on the output shaft that drive arrangement 1 has, and 7 inside of the organism of buttonholing machine are provided with pole setting 3, and pole setting 3 is fixed and is provided with push pedal 6, and organism 7 is stretched out to 6 one end of push pedal, and the push pedal 6 other end is fixed in pole setting 3, is provided with spring 4 between push pedal 6 and the organism 7. The lower end of the vertical rod 3 is provided with a cutter 5. The driving device 1 is installed and fixed on a driving device fixing bracket 71 of the frame 7, and the driving device 1 is transversely disposed at the rear end of the buttonholing machine frame 7, or the driving device 1 is disposed perpendicular to the buttonholing machine frame 7.

The output shaft of the driving device 1 is provided with a cam 2, the cam 2 is provided with a return surface 21 and a working surface 22, when the driving device 1 is in an initial non-working state, the return surface 21 is abutted against the push plate 6, and the spring 4 below the push plate 6 is in an original state.

When the driving device 1 drives, the restoring surface 21 of the cam 2 rotates on the push plate 6, so that the working surface 22 of the cam 2 rotates to the push plate 6, the highest point 221 of the working surface 22 abuts against the push plate 6, the push plate 6 presses the spring 4 downwards to drive the vertical rod 3 to move vertically downwards, and the downwards-pressed vertical rod 3 realizes button hole cloth cutting of the cutter 5.
