What is the importance of the wire loop in the use of industrial sewing machine spare parts?
The mechanism that hooks the thread loop in the industrial sewing machine spare parts is called the thread hook machine, which takes on the role of thread hooking, thread splitting, thread passing, threading off and bottom thread release.
Common sewing machines include rotary hooks, oscillating hooks, thread hooks, rotary hooks, and fork hooks. Rotary shuttle shuttles are mostly used on sewing machines with double-thread lock stitches, bar tacking machines and buttonhole machines. Curved needles are mostly used on chain stitch sewing machines, interlock sewing machines and two-, three-, four-, five-, and six-thread overlock industrial sewing machine spare parts. The main objects of hook hooks are single-thread chain stitch sewing machines, imitation bead edge machines, etc. Rotary hooks are mostly used on single thread chain stitch sewing machines and button sewing machines. When rotating the hook and hook, the difference is that the last thread loop enters the previous thread loop (self-connecting loop). The hook hook thread is the continuous cross form of the interconnection loop between the hook and the straight needle, and the hook and the hook.
The working characteristic of the thread take-up mechanism lies in the up and down movement of the thread take-up lever hole. The movement curve of the GC type industrial sewing machine spare part is branch-like. When the thread take-up lever moves downwards, the first is to supply the thread to the descending needle; When the hook hooks the upper thread, the upper thread is supplied to the hook again until the upper thread passes through the bobbin holder. When the thread take-up lever moves upward, it is responsible for pulling the upper thread out of the bobbin frame and tightening the stitches that have been formed in the sewing material to form a firm stitch, and draw the upper thread from the thread ball to the bottom Prepare for the formation of a stitch. Under normal circumstances, the stroke and trajectory of the thread take-up lever are relatively fixed. Due to its subordinate position, it is impossible to adjust the relevant dimensions of the industrial sewing machine spare part, and it should be installed in strict accordance with the positioning requirements.
The formation of the thread loop in the industrial sewing machine spare parts is different from the needle rising size. The needle lift should not be too large or too small. If the lift is too small, the loop width is not enough, which is not conducive to the entry of the sewing machine. The needle rebound is too large, which is advantageous for the stitcher to enter, but the thread loop is deflected due to the long time of the loop forming time, which makes it difficult for the stitcher to enter. Tests have shown that for sewing materials of normal thickness and density, the ideal stage of loop formation should be the most appropriate when the needle rises by about 2 to 3 mm.
