Qinhuangdao Zhongwei Precision Machine Parts Co., Ltd. specializes in the production of metal injection molding parts. The company has long-term strategic cooperation with domestic Yongyao, Desheng, Sanming and other rotary hook production international companies such as Japan's Zovin rotary shuttle, and Italy's Simon and other enterprises. Metal injection-molded hook case, material After joint research and efforts with Central South University, the products produced by the company not only have good wear resistance, but also have high hardness. Each year, Desheng supplies 600,000-800,000 hook cases, and 10 other manufacturers. -300,000 bobbin case supply.

Canvas Sewing Machine

Canvas sewing machine - the difference between the shuttle and the rotary shuttle

The shuttle is the main part of the canvas sewing machine. The bobbin case and the shuttle latch are connected to the shuttle body by the bobbin and the shuttle latch respectively. The bobbin case is connected to the shuttle body by the shuttle latch. The bobbin case is composed of a bobbin case, a bobbin guide shaft and a thread-pressing reed. The bobbin guide shaft is riveted and connected to the bobbin case, and the thread-pressing reed is fixedly connected to the bobbin case by screws. . For example, the GB4-1 canvas sewing machine is a shuttle structure. The inner diameter of the bobbin case is increased to φ27.5~32 mm, the top of the bobbin case is designed as a bobbin-shaped bobbin case, and the bobbin body is a convex-thick beam in the middle. The "floating thread" or "jumping thread" caused by the shuttle operation also makes the hook thread of the shuttle hook more fully, solves the problem of tight upper thread and easy bottom thread caused by the platform bobbin case head, and correspondingly reduces the operation time. Change the number of lines, improve work efficiency.

Improve the quality of sewing, and adapt to various types of heavy-duty materials such as large-scale heavy-duty container bag sewing machines, saddles, and hemp wheels.

The rotary hook is also one of the main parts in the sewing machine. The structure and shape are complex and the precision requirements are relatively high. Especially, it works continuously for a long time, and the working speed is high-speed operation. The guide rail of the shuttle frame can be placed in it and can run flexibly; the inner circle of the bobbin case in the inner shuttle frame is eccentric to its guide rail, so that the inner shuttle frame can be smoothly disconnected after the line is divided, and it can be taken out and locked by pulling the puller. Cover the entire bobbin case. In the same size shuttle, the new generation of rotary hook can reach the largest volume of the bobbin case, the inner diameter of the bobbin case can be between 34-60mm, and the height is between 16-25mm.

The good improvement improves the production efficiency, improves the production environment, improves the original rotary hook with small capacity, can not sew thick thread and thin sewing thickness, improves the sewing quality, and expands the applicable surface of the thick material sewing machine.

Canvas sewing machine is used for local decoration of container bags, canvas, sofas, tents, jeans, luggage, handbags, parachutes, etc. In short, in the rapid development of the electronic information industry era, thick canvas sewing machines are applied to various sewing fields, and the machine operating system only takes the concept of circuit performance as its evaluation. Technical indicators are challenged, and existing structural design patterns face new changes.
