In order to achieve the above purpose, the present invention provides the following technical solutions:
The utility model provides a sewing machine presser foot device and sewing machine, includes the processing backing plate, install the sewing machine body on the processing backing plate, install the support on the processing backing plate of sewing machine body front portion, install the fixed subassembly that is used for fixed cloth on the support, install the presser foot on the sewing machine body, be equipped with on the sewing machine body and be used for driving the presser foot removes the pressing component.
The fixing assembly comprises a sliding groove arranged on the support, and a first winding rod, a second winding rod and a third winding rod are connected in a sliding manner in the sliding groove.
The first winding rod is provided with a first fastening bolt, the second winding rod is provided with a second fastening bolt, and the third winding rod is provided with a third fastening bolt.
The processing backing plate is fixedly connected with a first fixing frame, a first telescopic rod is installed on the first fixing frame, the free end of the first telescopic rod is fixedly connected with a cloth collecting roller, a sliding rail is arranged on the processing backing plate, and the cloth collecting roller is in sliding connection with the sliding rail.
The sewing machine is characterized in that a rotating plate is connected to the sewing machine body through a fourth telescopic rod, a plurality of needle clamping devices are fixedly connected to the rotating plate, and clamping grooves for installing sewing needles are formed in the needle clamping devices.
The pressing component comprises a second telescopic rod fixedly connected to the first fixing frame, a fixing rod is arranged on the second telescopic rod, and a plurality of third telescopic rods are arranged on the fixing rod.
The presser foot is fixedly connected with the free end of the third telescopic rod.
Compared with the prior art, the sewing machine has the beneficial effects that the sewing machine can carry out various different angle adjustments on the sewing positions by driving the plurality of presser feet to move, can sort cloth, and can simultaneously sew the plurality of positions by adjusting the positions and the arrangement of the presser feet and the sewing needles, so that the sewing machine can be more convenient and faster in sewing.
