Base for placing yarn coil

Abstract

The invention relates to a base for placing a yarn coil. The base for placing the yarn coil comprises a positioning rod which is fixedly connected with a machine frame and a yarn coil positioning piece which is arranged on the positioning rod and is matched with an inner ring of the yarn coil. Especially, the yarn coil positioning piece comprises a plurality of positioning components which are arranged in the length direction of the positioning rod. Each positioning component comprises a yarn coil positioning body which is sleeved on the positioning rod and a plurality of positioning blocks which are distributed in the circumferential direction of the yarn coil positioning body, and each positioning block can be tightly matched with the inner ring of the yarn coil. According to the base for placing the yarn coil, the positioning components are arranged on the positioning rod, the positioning blocks on each positioning block are all tightly matched with the inner ring of the yarn coil, the stability of the yarn coil on the positioning rod is improved, the phenomenon that the tension of yarns is decreased due to looseness of the yarn coil is effectively prevented, so that yarn broken rate is reduced, and production efficiency is improved.

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...

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
