Problems solved by technology

[0003] This technology has the following disadvantages: 1. The upper and lower tugboat mechanisms are designed to cooperate with each other to prevent the formwork from slipping. Potential safety hazard of tearing; 3. The presser foot and the tug wheel can only be lifted or lowered at the same time, resulting in inconvenient operation, and the lifting height of the presser foot is fixed, which cannot be controlled according to the user's habits

Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing with specific embodiment:

[0024] A sewing machine based on a fully automatic template split synchronous wheel device, comprising a sewing machine main body, a tug wheel lifting mechanism 8 and a presser foot lifting mechanism 7 are arranged on the sewing machine main body, and the casing 6 rear cover of the sewing machine main body is provided with a lifting pressure mechanism. The tugboat electromagnet 1 and the lifting and pressing tugboat electromagnet 1 are attracted to make the swing crank drive the lifting and pressing tugboat crank shaft 2 to rotate, one end of the tugboat crank shaft 2 extends into the inside of the casing 6, and the lever 28 of the crank shaft is against the tugboat lifting right lever 11 The right end of the right end of the tugboat lifts the rotation fulcrum of the right lever 11 and is installed on the casing 6. Through the rotation of the lever, ...

Abstract

The invention belongs to the technical field of sewing machines, and particularly relates to a sewing machine based on an automatic template split synchronizing wheel apparatus. The sewing machine comprises a sewing machine body, the sewing machine body is provided with a drag wheel lifting and pressing mechanism and a lifting and pressing foot mechanism. A housing rear cover plate of the sewing machine body is provided with a lifting and pressing drag wheel electromagnet, a lifting and pressing foot electromagnet is disposed in the housing, and the lifting and pressing drag wheel electromagnet and the lifting and pressing foot electromagnet are used for respectively controlling the drag wheel lifting and pressing mechanism and the lifting and pressing foot mechanism to act. At the same time, a knee-operated lifting push rod is used for individually controlling the drag wheel lifting and pressing mechanism to act, so that the lifting height of a drag wheel can be adjusted at will, a cloth-dragging wheel can be lifted from a presser when a corner is sewed, and the presser can always pressed the cloth, the cloth can be normally sewed, the sewing performance can be raised, and the sewing effect can be ensured.

Description
