Problems solved by technology

If you need to sew on materials with different sizes and thicknesses, you need to adjust the intermediate presser assembly according to the thickest material. When sewing, the intermediate presser works at the adjusted height, which cannot be changed and cannot be well adjusted. The sewing material is pressed tightly, and the sewing effect is not good

Abstract

The invention discloses an intermediate presser foot lifting structure of a pattern-sewing machine. The intermediate presser foot lifting structure comprises a controllable motor, a driving gear, a driven gear, an intermediate presser foot lifting shaft and a lifting connecting rod, the controllable motor is connected with the driven gear which is in threaded connection with the driven gear, one end of the intermediate presser foot lifting shaft is connected with the driven gear, and the other end of the intermediate presser foot lifting shaft is connected with the lifting connecting rod. By the intermediate presser foot lifting structure of the pattern-sewing machine, height change of an intermediate presser foot can be controlled, and the height of the intermediate presser foot can be changed along with the thickness of materials when the materials different in thickness are sewed.

Description

technical field [0001] The invention relates to a pattern machine, in particular to an intermediate presser foot lifting structure of the pattern machine. Background technique [0002] Such as figure 1 As shown, the existing pattern machines are generally driven by a cylinder or an electromagnet lifting structure to lift the middle presser foot. Because the cylinder 11 (or electromagnet) is fixed on the body, the cylinder joint 12 is fixed on the cylinder rod of the cylinder 11, and is hinged with the connecting rod 14 through the hinge screw 13, and the connecting rod 14 is hinged with the lifting plate 16 through the hinge screw 15, and the lifting plate 16 is fixed on the machine body by the hinge screw 17; when the cylinder rod of the cylinder 11 stretches out and drives the cylinder joint 12 to stretch out, the connecting rod 14 stretches forward, pushing the lifting plate 16 to swing counterclockwise around the hinge screw 17, and the middle presser foot assembly 19 ...
