Computerized embroidery machine with dynamic keeping mechanism and working method of computerized embroidery machine

Abstract

The invention discloses a computerized embroidery machine with a dynamic keeping mechanism and a working method of the computerized embroidery machine, and relates to the technical field of computerized embroidery machines. The computerized embroidery machine comprises a shuttle box body component and the dynamic keeping mechanism; the shuttle box body component comprises a shuttle box with a needle plate, a fixed cutter and a movable cutter, wherein the fixed cutter and the movable cutter are arranged in the shuttle box; a needle plate hole is formed in the needle plate; the dynamic keeping mechanism is arranged in the shuttle box and comprises a keeping piece located on the back side of the needle plate, and a shifting piece, a torsional spring and a mounting pin; the mounting pin is fixedly connected to the back face of the needle plate; the shifting piece is rotatably arranged on the mounting pin in a sleeving mode; the torsional spring is arranged between the needle plate and the shifting piece to provide restoring force for the shifting piece, and the shifting piece is connected with the keeping piece; a central hole is formed in one end of the keeping piece; and when the movable cutter is opened relative to the fixed cutter, the movable cutter drives the shifting piece to rotate around the mounting pin, and meanwhile the shifting piece drives the keeping piece to linearly move towards the needle plate hole till the central hole is aligned with the needle plate hole. The embroidery quality and efficiency of the embroidery machine can be improved, the structure of the embroidery machine is simplified, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of computerized embroidery machines, and more specifically, to a computerized embroidery machine with a dynamic holding mechanism and its working method. Background technique [0002] The working principle of the computerized embroidery machine is that the upper thread and the lower thread work together, and finally the embroidery pattern is drawn on the fabric. At present, when the embroidery machine starts to embroider, it needs to bring the embroidery upper thread into the shuttle box through the needle, and the rotary hook separates the upper thread and cooperates with the bottom thread to tie a knot, and finally realizes the embroidery action. However, the embroidery action of the existing embroidery machine has the following defects: 1. If the length of the upper thread is not enough or the tension is not enough during embroidery, it is easy to appear that the first stitch embroidery is not in place, a...

Problems solved by technology

However, the embroidery action of the existing embroidery machine has the following defects: 1. If the length of the upper thread is not enough or the tension is not enough during embroidery, it is easy to appear that the first stitch embroidery is not in place, and it is easy to lose the bottom thread, which will cause the upper thread and the bottom thread to fail. A knotted state will eventually lead to a reduction in the quality of the embroidery pattern; 2. Inadequate starting of the embroidery machine will result in missed stitches or a few stitches before the bottom thread can be picked up, which will lead to reduced efficiency and reduced quality

However, this embroidery machine needs to set a special electromagnet as a driving mechanism to drive the thread-catching spring to catch the upper thread, which has a complex structure and requires additional driving costs.
