Sewing machine needle-changing-free equipment based on high-end equipment manufacturing

Abstract

The invention relates to the technical field of sewing machines, and discloses sewing machine needle-changing-free equipment based on high-end equipment manufacturing. The sewing machine needle-changing-free equipment comprises a machine body, the bottom of the machine body is fixedly connected with a machine base, the right side of the machine body is movably connected with a power wheel, and themachine body is movably connected with a movable rod through a machine head. According to the sewing machine needle-changing-free equipment based on high-end equipment manufacturing, through upward movement of the movable rod, an arc-shaped sliding block in a second-stage accelerating plate moves upwards under cooperation of the sliding groove, variable polar plates at the two sides move inwards,and then an induced magnetic field is generated; and through an induced magnetic field and a positive electric contact at the top of the second-stage accelerating plate, magnetic fields generated bycoils are used in cooperation, and the magnetic fields are superposed, so that the magnetic induction intensity is improved, the Lorentz force is increased, the movable rod is stressed to fall down inan accelerated manner, cloth is pierced, the defect that needles need to be replaced frequently when the sewing machine faces different materials is overcome, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a sewing machine needle-free device manufactured on the basis of high-end equipment. Background technique [0002] A sewing machine uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing materials. The sewing machine can sew cotton, hemp, silk, wool, Man-made fibers and other fabrics and leather, plastic, paper and other products, the stitches are neat and beautiful, flat and firm, fast sewing speed, easy to use, and meet the needs of modern life. [0003] The publication number is CN108060514A, and the publication date is May 22, 2018. The Chinese invention patent has announced a sewing machine thread take-up mechanism and a sewing machine, including a thread take-up shaft that can swing back and forth, a long thread take-up plate seat fixed to the thread take-up shaft, and a long thread take-...
