CN224160763U - A straight-pull type magnetic damping twisting machine - Google Patents

Abstract

This application discloses a straight-pull type magnetic damping twisting machine, including a stationary part supporting the yarn bobbin and a rotating part for twisting the yarn. The stationary part includes a stationary base, with a guide rod and a conductor disk on the upper side of the stationary base. The yarn bobbin and the conductor disk are connected and sleeved on the outside of the guide rod. The edge of the conductor disk is located between two magnetic poles. The conductor disk (material: aluminum, copper) cuts the magnetic field lines of the static magnetic field between the magnetic poles, generating a reverse damping force. Under the pulling action, the yarn bobbin rotates accordingly, so that the yarn is subjected to balanced stretching and tension. When the power is cut off and the machine stops, when the external power is lost, the damping force is greater than the rotation due to inertia, achieving instant braking. This avoids the problems of slippage and tangled yarn caused by inertial rotation, and effectively uses magnetic damping force to solve the tension requirements of different yarn materials, diameters and twists.

Description

Straight pull type magnetic damping twisting machine

Technical Field

Background

The intelligent one-step twisting machine has the innovative design that the first twisting part of the yarn tube is static and depends on the flyer to rotate and unwind, and the advancement of the modern textile technology is presented. However, such twisting machines present challenges when integrated with some of the enterprises' original conventional wire drawing machine winding systems (lacking twisting functionality). The tows rolled by the traditional wire drawing machine are often loose and have different lengths, and when entering the flyer wire holes of the intelligent twisting machine, the tows are easy to knot due to uneven friction and tension among yarns, so that the quality of the yarns is reduced, the twisting machine is stopped frequently, and the production efficiency is seriously influenced. To cope with this problem, enterprises have to invest in horizontal or vertical winding and twisting machines additionally to ensure that the tows have necessary twist and uniformity before entering the twisting machine, which undoubtedly increases the operation cost and complexity of the production process.

To address this dilemma, a twisting machine is proposed in the patent application No. 202322236009. X. The design ensures that the yarn tube passively rotates under the action of yarn conveying and pulling, and the yarn is naturally stretched in the process of pulling downwards, so that tows with different lengths reach basically consistent length and are directly twisted at the yarn tube. The design skillfully utilizes the natural stretching characteristic of the yarn, effectively solves the problems, and avoids the investment of extra equipment.

However, this design also faces the new challenge that after shut down, the bobbin will continue to rotate for some time due to inertia, and it is difficult to achieve an effective shut down, which creates problems for subsequent yarn finishing and winding operations. Therefore, the existing structure is further improved to solve the problem of inertial rotation of the yarn tube after shutdown, and the problem becomes the key of continuous optimization of the design.
