[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material, so that one or more layers of sewing material are interwoven or sewn together.

[0003] In order to sew high-quality stitches and ensure good feeding quality of the feed dogs, existing sewing machines require the presser foot to have appropriate presser foot pressure to press the sewing material tightly. However, when sewing elastic materials such as sponge blocks, the outer part of the sponge block will bulge upward after the middle part is pressed tightly, resulting in unevenness. In this case, the overall sewing quality is uneven and the yield rate is low. Utility Model Content

[0004] The utility model provides an auxiliary component of a sponge presser foot, which can press the periphery and edge parts of a sponge block downwards during the sewing process, thereby avoiding the peripheral bulge affecting the quality during the sewing process, and the air blowing and pressing limit is used to avoid irreversible deformation of the sponge, thereby ensuring the shape and quality of the product and improving the yield of the finished product.

[0010] As a preferred embodiment of the above technical solution, a lifting assembly is connected to the top of the other end of the connecting rod, and the lifting assembly is used to drive the connecting rod to move up and down. The two ends of the tension spring are fixedly connected to the positioning seat and the connecting rod respectively.

[0011] As a preferred embodiment of the above technical solution, the air vent is communicated with the insertion cavity, the air vent is arranged in the same direction as the positioning seat, and a fan is connected to the outside of the ventilation pipe.

[0012] As a preferred embodiment of the above technical solution, the first locking plate is arranged on the front side of the lifting seat, and the pressing plate and the first locking plate are integrated.

[0013] As a preferred embodiment of the above technical solution, the top of the lifting seat is connected to a second positioning plate through a locking thread, the top of the lifting seat is connected to a lifting plate, and the top of the lifting plate is connected to a hydraulic lifting rod, which is used to drive the auxiliary component to lift as a whole.

[0014] The utility model provides an auxiliary component of a sponge presser foot, which comprises a presser foot block, a vent pipe and an auxiliary component. The entire pressing body and the entire auxiliary component can be driven up and down by a lifting component and a hydraulic lifting rod respectively. When the sponge block enters the bottom of the auxiliary component, the entire auxiliary component is driven to move downward.
