A base for placing rolls of yarn

Abstract

The invention relates to a base for placing a yarn roll, which includes a positioning rod fixedly connected with a frame, a wire roll positioning member arranged on the positioning rod and matched with the inner ring of the yarn roll, in particular, a wire roll The positioning member includes a plurality of positioning assemblies arranged along the length direction of the positioning rod, each positioning assembly includes a wire coil positioning body sleeved on the positioning rod, and a plurality of positioning blocks are distributed along the circumference of the wire coil positioning body, each All the positioning blocks can closely fit with the inner ring of the yarn roll. In the present invention, a plurality of positioning components are arranged on the positioning rod, and multiple positioning blocks on each positioning component are closely matched with the inner ring of the yarn roll to improve the stability of the yarn roll on the positioning rod, effectively It can effectively prevent the reduction of yarn tension caused by the loosening of the yarn roll, thereby reducing the yarn breakage (thread) rate and improving production efficiency.

Description

technical field [0001] The invention relates to a textile machinery device, in particular to a base for placing yarn rolls. Background technique [0002] As we all know, the main purpose of the base for placing the yarn roll is to place the yarn roll on the base stably. For example, Chinese invention patent CN1023033667A discloses a yarn roll fixing device, which includes a The fixed rod at the upper end, the fixed ring that is sleeved on the fixed rod and can slide along the length direction of the fixed rod, the middle of the base is provided with a cylindrical groove, the bottom end of the fixed rod is fixedly connected to the inside of the groove, and is located in the groove The fixed rod inside and placed under the fixed ring is also sleeved with a spring. It is mainly through the setting of the spring, so that the yarn roll can be fixed on the fixed rod at will, and different yarn rolls can be fixed so that it is not easy to fall off, but when the yarn on the yarn ro...

AI Technical Summary

Problems solved by technology

It is mainly through the setting of the spring, so that the yarn roll can be fixed on the fixed rod at will, and different yarn rolls can be fixed so that it is not easy to fall off. Small, the spring will gradually return to its original state. At the same time, under the action of the yarn guide (thread) mechanism, it is easy to drive the inside of the yarn roll and the fixed ring to loosen, making the tension of the yarn smaller, thereby increasing the yarn guide. The (thread) mechanism is prone to yarn breakage (thread), which directly affects production efficiency
