Description

A kind of ultrahigh speed sewing machine

Technical field

This utility model relates to wool spinning and weaving machinery equipment technical field, especially relates to a kind of sewing machine.

Background technology

Sewing machine has another name called Linking machines, binding-off machine etc., is apparel industry, and the particularly controlling of woolens industry product final mass and production unit price produces equipment.The difference of the old sewing machine threading large needle because using is divided into two kinds:

1, the staight needle sewing machine of staight needle is used, design speed about 500 turns, have superiority when sutures is the special easily broken sutures such as cashmere, but owing to it is to utilize rotating shuttle to rotate to have coordinated stitching with threading large needle, when rotating shuttle does 360 ° of degree rotations, suture be have also been made distortion, thus it is sewing up gap difficulty lopping, easily breaking joint hair, product the most therefore elastic force is poor, and owing to being staight needle, relatively thin product set eye does not draws eye, then be not suitable for sewing up, the most abandoned by market.

2, looper is used to do the looper sewing machine of threading needle, the inside and outside grooved cam group of main flow and link transmission twin shaft sewing machine, it is typically designed rotating speed 350-450 rev/min, the single shaft sewing machine of brute spring without groove after improvement, design speed about 600 revs/min, reinforced rear speed also increases, but its complete machine becomes to rotate heavy, and noise is especially big, and working life is short, within even three months, occur as soon as critical part major injury, need alternate maintenance.Existing twin shaft, single shaft looper sewing machine, its action controlling to hook line device is completed by two cams, and one controls to move up and down, and one controls side-to-side movement, no matter staight needle or looper sewing machine, has been coordinated stitching by hooking both line device and threading large needle.

As shown in Figure 1, 2, old main flow looper sewing machine, no matter single shaft or twin shaft, is all the action that controls to hook line device of the curve of profit cam, thus curve is big, there is obvious dead point, speed can not be fast, and has vibration, and noise is big, quick abrasion, hooking line device 101 and easily hook line loosely, so that occurring coil 102 to slip voluntarily, causing large needle 103 can not accurately pass coil, occur jumping seam, producing and produce flaw, frequently, maintenance cost is high in maintenance, production efficiency is low, working environment because noise is big, machine vibration and be deteriorated.

Summary of the invention
