Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of circular knitting machines, and particularly relates to a line-breaking-preventing circular knitting machine. BACKGROUND

[0002] A circular knitting machine is also called a circular weft knitting machine. The circular knitting machine has many advantages such as high speed, high output, fast pattern change, good fabric quality, less process and strong product adaptability, and therefore develops rapidly. However, when the circular knitting machine produces a fabric, the textile thread may be broken due to various reasons such as excessive tension or friction with the equipment. Therefore, a circular knitting machine with a line-breaking-preventing function is needed.

[0003] A yarn feeder of a circular knitting machine is disclosed in Chinese Patent No. CN211367926U. The yarn feeder comprises a shell, a yarn guide assembly and a yarn breakage prompting assembly. The yarn guide assembly comprises two connecting rods rotatably connected to the shell, two shafts fixed to the connecting rods and wheels connected to the shafts. The yarn passes through the wheels from top to bottom on the side away from the shell. The yarn breakage prompting assembly comprises a torsion spring, an infrared sensor and a controller. When the yarn is broken, the torsion spring drives the connecting rod to rotate, and the infrared sensor senses the change in the height position of the wheel. The controller controls the power supply of the circular knitting machine to be turned off after receiving the signal. The shaft is provided with a limiting block for fixing the wheel to the shaft, and the length of the wheel is greater than the swing distance of the yarn on the wheel. The utility model effectively prevents the wheel from slipping along the shaft axis on the shaft, avoids the influence of the accumulated lint at the turning part of the shaft on the wheel, and further prevents the influence of the accumulated lint on the yarn tension, so that the yarn is not easy to break.

[0004] Although the yarn feeder of the circular knitting machine can effectively prevent the influence of the accumulated lint at the turning part of the shaft on the wheel by using the yarn guide assembly and the yarn breakage prompting assembly, when the yarn is broken, the textile thread will rebound due to the tension, and the worker needs to reconnect the textile thread, which is very inconvenient. UTILITY MODEL CONTENTS

[0005] The utility model aims at the existing technical problems, and provides a line-breaking-preventing circular knitting machine, which can prevent the textile thread from breaking and rebounding after breaking.
