Embodiment Construction

[0019] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] Such as figure 1 As shown, the present invention includes a support 1, a top plate 2, a sewing machine 3, a telescopic support 4, an annular transfer rail 5 and a telescopic mechanism 6;

[0022] The top plate 2 is fixed on the top of the bracket 1, and the top plate 2 is provided with a circular through hole;

[0023] The sewing machine 3 is fixed on the top plate 2, and the circular through hole is positioned directly below the sewing needle of the sewing machine. A circular cloth pressing cover 31 can also be slidably provided at the lower end of the sewing needle. Any vertical cross-section is an arc that protrudes upwards in the middle, and a strip-shaped opening is provide...

Abstract

The invention provides a circular buttonhole stitching machine which comprises a support, a top plate, a sewing machine, a telescopic support, a circular rotary rail and a telescopic mechanism. The sewing machine is fixed to the top plate. A circular cloth pressing cover is fixed to the lower portion of a sewing needle in a slidable mode. The circular rotary rail is located under the sewing needle of the sewing machine. The circular rotary rail is not higher than the upper surface of the top plate. The circular rotary rail is fixed to the telescopic support. The telescopic mechanism is fixedly connected with the telescopic support. The sliding direction of the circular cloth pressing cover is the same as the telescopic direction of the telescopic mechanism. By rotating the circular rotary rail, cloth is automatically driven to rotate, the circular rotary rail drives the circular cloth pressing cover to slide forwards and backwards, and therefore the cloth can be conveniently driven by the circular rotary rail to rotate by a certain angle to be sewn again after being sewn by the sewing needle forwards and backwards, operation is easy and convenient, work efficiency is improved, and lots of labor is emancipated.

Description

technical field [0001] The invention belongs to the field of sewing equipment, in particular to a round hole buttonhole machine. Background technique [0002] In the prior art, the edge banding of round holes is generally done manually, which is inefficient and requires a lot of labor. Contents of the invention [0003] In view of this, the present invention aims to provide a buttonhole machine for round holes. While sewing automatically, the ring-shaped rail on the bottom surface drives the cloth to rotate, realizing the automatic sewing of the round holes. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] A round hole buttonhole machine, comprising a bracket, a top plate, a sewing machine, a telescopic bracket, a ring-shaped transfer rail and a telescopic mechanism; [0006] The top plate is fixed on the top of the bracket, and the top plate is provided with a circular through hole; [0007] Th...
