technical field

The utility model relates to the field of novel yarns, in particular to a bidirectional wrapping parallel spinning device.

Background technique

Parallel spinning, also known as wrapping spinning, uses a hollow spindle for spinning, and the yarn produced by a parallel spinning machine is called parallel yarn, also known as P.L yarn. In parallel spinning, a non-twisted parallel fiber strip is used as the core yarn, and the outsourcing filament or spun staple yarn is wound on the bobbin after being wrapped into yarn. Since the fibers of the core yarn are not twisted, it is called Parallel spinning. When the yarn is stretched, the filament exerts radial pressure on the short fiber sliver, which causes friction between the short fibers and makes the parallel yarn have a certain strength.

Parallel yarn can replace thread, and it is suitable for untwisted, weak twist and pile products with its unique yarn structure, giving people a high-end feeling. However, the current parallel spinning devices all use a single filament or spun yarn for outsourcing, which limits the type of spinning and the quality of the yarn. In view of this, the utility model provides a two-way wrapping parallel spinning device, which includes a hollow spindle, on which the upper hollow cylinder and the lower hollow cylinder are respectively connected through a bearing structure, and the upper hollow cylinder and the lower hollow cylinder The bottom of the belt is connected with an upper pulley and a lower pulley respectively, and an upper belt and a lower belt are respectively connected to the upper pulley and the lower pulley, and the upper pulley and the lower pulley are driven by the upper motor through the upper belt and the lower belt Driven by the upper and lower motors, the upper and lower motors drive the upper and lower belt pulleys to rotate through the upper and lower belts, and then drive the upper and lower hollow cylinders to rotate, and are integrated on the upper and lower hollow cylinders respectively Connected with an upper disc and a lower disc, the first filament and the second filament are respectively placed on the upper disc and the lower disc, and an upper round hole and a lower round hole are respectively opened on the hollow spindle, and the upper round hole Located on the top of the upper hollow tube, the lower hole is located on the top of the lower hollow tube, the first filament and the second filament are fed into the hollow spindle through the upper hole and the lower hole. The utility model uses double filaments to be placed in parallel up and down to realize double wrapping of the core yarn in parallel spinning, thereby improving the quality of the yarn. At the same time, the double filaments can use different colors or different materials, thereby enriching the appearance of the yarn. Increase the added value of products.
