Description

Yarn storage device of textile machine

Technical Field

The present invention relates to the field of textile processing.

Background

Spinning is an ancient activity, and since the prehistoric times, mankind has become aware of spinning shorter fibers into long yarns, which are then woven into fabrics. Spinning is the practice of using animal or vegetable fibers twisted together into a continuous, infinitely extending yarn suitable for weaving.

The twist of the yarn itself will cause the fibers to naturally and tightly bind together, thus making weaving or knitting very advantageous. In a high-speed spinning machine, it is required that continuous yarn from a spinning device is stored in one place and a stable tension is obtained. However, during the storage process, the yarn storage device also rotates at a high speed, and the yarn running direction and the position are fixed, so that the yarn is easily wound at the same position on the yarn storage device during the yarn storage process, and the occupied space is large, and the storage amount is low.

Disclosure of Invention

The invention aims to solve the problem that the existing device occupies a large space when storing yarns.

In order to achieve the purpose, the basic scheme of the invention provides a yarn storage device of a textile machine, which comprises a motor, a frame, a planetary gear train rotationally connected with the frame and an auxiliary roller fixing frame arranged on the frame at the periphery of the planetary gear train, wherein the planetary gear train comprises a sun gear driven by the motor, a planetary carrier fixedly connected with the frame and a plurality of planetary gears meshed with the periphery of the sun gear and rotationally connected with the planetary carrier, planetary gear shafts are all in splined connection with the planetary gears and the planetary carrier, a sliding groove is arranged at the middle section of each planetary gear shaft, a sliding block sliding in the sliding groove is fixedly connected onto the frame at one side of the sliding groove, a yarn storage roller is fixedly connected to the lower end of each planetary gear shaft, tensioning rollers corresponding to the number of the yarn storage rollers are circumferentially arranged on the auxiliary roller fixing frame, the tensioning.

The principle of the basic scheme is that when yarns are required to be collected and stored, the head ends of a plurality of groups of yarns are respectively fixed on a yarn storage roller, then a textile machine starts to work, a starting motor drives a sun gear to rotate, the sun gear rotates to drive a planet gear to rotate and simultaneously drive a yarn storage roller to rotate, when the planet gear rotates, a planet gear shaft reciprocates up and down due to the corresponding arrangement of a sliding block and a sliding groove, the yarn storage roller is driven to reciprocate up and down at a constant speed in the process of rotating and winding yarns, because the direction and the speed of the yarns transmitted from the textile machine to the yarn storage roller are stable, the yarns are uniformly wound on the yarn storage roller due to the up-down movement of the yarn storage roller, the yarns are tensioned by a tensioning roller when the yarns are wound, a yarn breaking mechanism is triggered after the yarn storage roller is wound to a certain amount of yarn diameter and is widened, and the yarns between the textile machine and, the worker processes the thread end of the yarn and then takes the yarn storage roller down for the next stage of work.

The basic scheme has the advantages that the basic scheme has the beneficial effects that,

1. the invention completes the simultaneous operation of the plurality of yarn storage rollers through the planetary gear train to store yarns, ensures the uniform yarn winding by the up-and-down reciprocating movement of the yarn storage rollers, and avoids the problems of overlarge occupied space and low storage capacity caused by nonuniform winding during yarn storage.

2. The yarn breaking mechanism is controlled through the diameter change of the yarn storage roller, the problem that yarns are wound too much is avoided, and the quantitative storage of the yarns is realized.

3. The tension roller avoids the problem that the tension force is insufficient due to the fact that the distance between the textile machine and the yarn storage roller is too far, and the yarn storage efficiency is higher.

And the yarn cutting mechanism comprises a pressing plate, a pressure spring arranged between the pressing plate and the rack and a cutting lever arranged below one side of the pressing plate, a pressing block is arranged on the lower surface of one side of the pressing plate, which faces the cutting lever, a bearing block is arranged on the upper surface of one side of the cutting lever, which is opposite to the pressing block, and the other side of the cutting lever is obliquely connected with a cutting plate capable of cutting yarns. When the number of the yarns wound on the yarn storage roller is increased and the diameter of the yarn storage roller is changed, the yarn storage roller gradually presses the pressing plate to enable the pressing block to be in contact with the bearing block, the pressing block presses the bearing block downwards to enable the cutting plate at the other end of the cutting lever to move towards the direction of the yarns, after the pressing block presses the bearing plate to a certain degree, the cutting plate cuts off the yarns, and quantitative yarn storage of the yarn storage roller is guaranteed.

Scheme three, this is the preferred of basic scheme, tensioning roller surface is equipped with and carries out spacing groove for the yarn. The setting of spacing groove has avoided the yarn to produce slip and displacement on the tensioning roller surface.

And the scheme is the optimization of the basic scheme, the device further comprises a controller, a pressure sensor is arranged on the pressure spring, and the pressure sensor and the motor are controlled by the controller. When the diameter of storing up the yarn roller changes to certain degree, the pressure spring can bear certain pressure, and pressure that pressure sensors detected the pressure spring and bore then feeds back data to the controller, and controller control motor stall for planet wheel and store up yarn roller stall all, accomplish and store up yarn work.

According to the fifth scheme, the preferable basic scheme is that an air duct is arranged below the sun wheel shaft, dust suction blades fixedly connected with the sun wheel shaft are arranged in the air duct, and a dust suction port is formed in the side wall of the air duct. The sun wheel drives the dust suction blades to rotate when rotating, dust existing on the yarns is sucked into the air duct through the dust suction port, and the dust is cleaned.
