How should the plastic knitting manufacturer solve the problem of broken threads in the woven bag?
Woven bags are one of the most commonly used packaging plastic products at present. They are listed in the very important environmental protection category like cardboard boxes. With the increasing requirements for woven bags, we have also highlighted some problems, that is, some small faults that often occur during the production of woven bags, and disconnection is one of the more common small accidents. How can we solve it?
Thread breakage is the most common failure encountered in sewing woven bags. The quality of the stitches is not satisfactory, the machine is not adjusted properly, the thread passing parts have sharp openings, the operation method is problematic, and the needle is not sufficiently cooled. . Woven bags are not allowed to be short-lined.
When using a lock-type stitch knitting bag sewing machine to sew uneven thickness products, in addition to considering each of the above reasons, you should also pay attention to the thread breakage caused by two hooks. It is well known in the sewing machine industry that due to the need to distribute the action cycle in the design, the transmission ratio between the shaft and the rotary hook of the lock stitch bag sewing machine is 1: 2. That is, the upper shaft rotates once, and the hook shaft rotates for two weeks.
Therefore, during the sewing process of the woven bag, the needle rotates the rotary hook for two weeks at a time. If the hook hook is threaded twice, it will conflict with the retraction of the upper thread, which will cause the suture to be broken. More and more plastic weaving manufacturers have summed up their experiences to face and solve these problems. I wonder if you have solved them? http://eqp2p.com
