Description

Technical Field

[0001] The present invention relates to the technical field of sewing machines, in particular to a sewing machine presser foot device and a sewing machine. Background Art

[0002] Sewing machines play a vital role in the modern textile and garment industry. As one of the key components of a sewing machine, the presser foot mechanism has undergone several stages of development. Early versions were relatively simple and had relatively limited functions. With the continuous advancement of technology, today's presser foot mechanisms are more sophisticated in design, adapting to fabrics of varying thicknesses and materials, improving sewing precision and efficiency.

[0003] However, in existing sewing machines, the presser foot mechanism can only be manually pressed to feed the material. During the sewing process, only one presser foot can be pressed. However, during the sewing process, multiple different seams may need to be sewn simultaneously. Therefore, a sewing machine that can sew multiple locations simultaneously during sewing is needed to meet the needs of users. Summary of the Invention

[0004] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the present invention is to provide a sewing machine presser foot device and a sewing machine, which can adjust the sewing position to a variety of different angles and sew multiple positions simultaneously.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A sewing machine presser foot device and a sewing machine, comprising a processing pad, a sewing machine body being mounted on the processing pad, a bracket being mounted on the processing pad at the front of the sewing machine body, a fixing component for fixing fabric being mounted on the bracket, a presser foot being mounted on the sewing machine body, and a pressing component for driving the presser foot to move being provided on the sewing machine body.

[0007] The fixing assembly includes a sliding groove arranged on the bracket, and a first winding rod, a second winding rod and a third winding rod are slidably connected in the sliding groove.

[0008] A first fastening bolt is installed on the first winding rod, a second fastening bolt is installed on the second winding rod, and a third fastening bolt is installed on the third winding rod.

[0009] A first fixing frame is fixedly connected to the processing pad, a first telescopic rod is installed on the first fixing frame, a cloth collecting roller is fixedly connected to the free end of the first telescopic rod, a slide rail is provided on the processing pad, and the cloth collecting roller is slidably connected to the slide rail.

[0010] The sewing machine body is connected to a rotating plate via a fourth telescopic rod, and a plurality of needle holders are fixedly connected to the rotating plate. The needle holders are provided with slots for installing sewing needles.

[0011] The pressing assembly includes a second telescopic rod fixedly connected to the first fixing frame, a fixing rod is installed on the second telescopic rod, and a plurality of third telescopic rods are installed on the fixing rod.

[0012] The presser foot is fixedly connected to the free end of the third telescopic rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the present invention can adjust the sewing position to a variety of different angles by driving multiple presser feet to move, and can arrange the fabric. By adjusting the position and arrangement of the presser feet and sewing needles, multiple positions can be sewn simultaneously, thereby ensuring that sewing can be more convenient.
