Commonly used multi-shuttle box mechanism
The multi-shuttle box device has various forms when the shuttle box is changed. At present, lift-type multi-shuttle box devices are widely adopted in my country. According to the location of the shuttle seat of the multi-shuttle box and the number of shuttle boxes, it can be divided into two types of mechanisms: 1. Single-sided multi-shuttle box mechanism The shuttle seat is located on one side of the reed seat, and the other side is a fixed single-edge box. For example, 1×4 indicates a small-side four-box mechanism; 1×2 indicates a single-side two-box mechanism. It can only weave certain fabrics with an even number of weft threads. That is to say, the shuttle carrying each kind of weft yarn must be returned to the original shuttle box on the side of the multi-shuttle box before other shuttle boxes can be changed. Therefore, the preparation of the shuttle box chain is relatively simple. As long as the weft color matching cycle table is listed, the shuttle box chain can be compiled accordingly. But be careful not to jump the shuttle box. The number of shuttles used is the total number of shuttle boxes on both sides minus 1. 2. Bilateral multi-shuttle box mechanism: The shuttle seats of the multi-shuttle box are closed on both sides of the reed seat. For example, 4×4 means a double-sided four-box mechanism. 2×2 means double-sided two-box mechanism. It can weave certain fabrics with an odd or even number of weft yarns. According to the mutual lifting relationship between the shuttle boxes on both sides, it can be divided into two forms: (1) Same lifting type: the shuttle boxes on both sides lift and lower at the same time. The structure is simple and only requires one set of mechanisms to control the shuttle box change, but it is often used The number of shuttles is only half of the total number of shuttle boxes on both sides. (2) Different lifting type: The shuttle boxes on both sides can be raised and lowered at will. The structure is complex and requires two sets of mechanisms for controlling the shuttle box change. The number of shuttles used is the total number of shuttle boxes on both sides minus 1.
