[0002] Mattresses have become an indispensable bedding in modern people's lives. Mattresses can increase the comfort of the bed and help improve people's sleep quality. Generally, mattresses are composed of filling materials wrapped in outer covering materials. During the processing of the mattress, after the outer covering material wraps the mattress, the side edges of the outer covering material need to be sewn to achieve the sealing of the mattress. However, most of the existing mattresses are packaged by manual sewing, which has low processing efficiency and high production cost. Therefore, it is necessary to design a sewing device for mattress covering.

[0003] A sewing device for mattress covering is disclosed, with the publication number CN217378200U. The beneficial effects are as follows: a driving mechanism in the sewing device can drive a sewing machine head to rise and fall, thereby automatically sewing the side edges of the covering material of the mattress through the automatically rising and falling sewing machine head, thereby improving the mattress production efficiency, eliminating the need for manual sewing processing to reduce production costs, and achieving a better sewing effect on the side edges of the covering material.

[0004] The sewing head of the sewing device for mattress covering is raised and lowered, thereby automatically sewing the side of the covering material of the mattress through the automatically raised sewing head.
