Description

Technical Field

[0001] The utility model relates to the technical field of staple fiber two-for-one twisting machines, in particular to a yarn bobbin limiting device of a staple fiber two-for-one twisting machine. Background Art

[0002] The double twister is a twisting device, which is essentially a doubling device (multiple strands are combined into one strand), called a doubling machine. It can achieve two twists in one turn, and the twisting efficiency is doubled compared to traditional twisting equipment. The winding capacity is increased, there is no joint in 10,000 meters, the twisting quality is greatly improved, and the layer height is lower.

[0003] Most of the existing two-for-one twister yarn bobbin limiting devices are inconvenient to operate. For example, in the utility model with patent number CN215828033U, in the textile industry, the yarn bobbin fixing column is designed to be fixed and cannot be adjusted according to the actual needs of the yarn bobbin. When the bobbin begins to be wound with short fiber materials, as the short fibers are continuously wound up, the diameter of the bobbin gradually increases and the thickness is also growing. The baffle becomes an obstacle. The short fibers that contact the baffle cannot continue to be wound smoothly. They begin to squeeze and accumulate, which not only affects the quality of the yarn, but also makes it difficult for the bobbin to rotate. In some cases, the bobbin may even be completely stuck due to the friction between the short fibers and the baffle, causing the entire machine to stop operating. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model realizes the purpose of moving the fixed column through a threaded rod, a sleeve, a sliding rod, a slider, a threaded cylinder and a slide groove, and designs the fixed column to be adjustable, which effectively reduces the problem caused by the transition of short fibers due to winding. The situation of the yarn tube getting stuck is reduced, and the position of the fixed column can be adjusted according to the actual needs of the operator. When the short fibers are over-entangled during the spinning process, the operator can quickly adjust it to avoid the embarrassing situation that the yarn tube is stuck due to fiber winding. This not only reduces the downtime of the machine, but also reduces the burden on maintenance personnel. It can be applied to the production of different types of yarns. Whether it is coarse yarn or fine yarn, it can be adapted to production needs through simple adjustments, ensuring the smooth operation of the production line, thereby greatly improving production efficiency and product quality.
