Two-for-one twister yarn roll with adjustable pressure

Technical Field

The utility model relates to a textile sector, especially a two-for-one twister yarn book of pressure adjustable.

Background

A two-for-one twister is a twisting device that can bind two or more single yarns into a strand by twisting. The front single yarn reels in the two-for-one twister are generally directly sleeved on a rotating shaft and passively rotate under the action of yarns, and then the tension of the yarns needs to be adjusted through a tensioner; although the tensioner can achieve the effect of adjusting the tightness of the yarn, the tensioner can cause yarn flying, abrasion and even breakage, so that a device capable of adjusting the resistance of the yarn coil during rotation is needed at present to avoid yarn damage caused by the tensioner.

On the other hand, when the two-for-one twister is operated at a high speed, the yarn coil can also rotate at a high speed at the moment, the yarn coil is easy to shake, the noise is high, the friction between the yarn coil and the shaft and between the upper side and the lower side of the yarn coil and other parts is increased, and the accidental breakage of yarns is caused. There is therefore a need to solve the above problems.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

By figure 1 to 3 provide, the utility model discloses a vertical fixed axle 1 of placing, the cover is equipped with on the fixed axle 1 and can rotates a yarn section of thick bamboo 2, the upper and lower both ends of a yarn section of thick bamboo 2 are fixed with magnetic disc 3 and lower magnetic disc 4 respectively, be fixed with the electromagnetic disc 5 that is located 4 below of lower magnetic disc on the fixed axle 1, the lower terminal surface of lower magnetic disc 4 and the up end of electromagnetic disc 5 all are equipped with friction disk 6, supporting disk 7 that can reciprocate is installed to the upper end of fixed axle 1, first magnetic disk 8 is installed to the lower extreme of supporting disk 7, be connected with pressure spring 9 between first magnetic disk 8 and the supporting disk 7.

In order to adjust the pressure better, the electromagnetic disc 5 is controlled by a controller 10, and the upper magnetic disc 3, the lower magnetic disc 4 and the first magnetic disc 8 are permanent magnet discs; wherein the upper end surface of the upper magnetic disk 3 and the lower end surface of the first magnetic disk 8 are homopolar; the lower end surface of the lower magnetic disc 4 and the upper end surface of the electromagnetic disc 5 are homopolar.

The diameter of the lower disc 4 is larger than that of the upper disc 3 for better support of the yarn.

In order to better realize the up-and-down movement and the limiting of the supporting plate 7, the fixing shaft 1 is provided with threads, the fixing shaft 1 is screwed with a nut 11 positioned above the supporting plate 7, the upper end of the fixing shaft 1 is provided with a sliding groove in the up-and-down direction, and the supporting plate 7 is fixed with a sliding block arranged in the sliding groove.

In order to reduce excessive wear between the friction discs 6, balls are mounted on the end faces of one of said friction discs 6.

The utility model discloses during the use, at first through revolving nut 11 soon, can take out and place a yarn section of thick bamboo 2, the yarn winding forms the yarn book on a yarn section of thick bamboo 2. After the yarn barrel 2 is placed, the first magnetic disc 8 and the supporting disc 7 are sleeved on the rotating shaft according to the state shown in the attached drawing 1, and the nut 11 is screwed to realize fixation, so that the yarn barrel 2 is prevented from popping upwards.

Then the rotation resistance of the yarn barrel 2 can be adjusted according to the requirement; the mode of adjustment is mainly divided into two types, one type of electromagnetic disk 5 is not electrified, and the other type of electromagnetic disk 5 is electrified.

When the electromagnetic disc 5 is not electrified, namely the electromagnetic disc 5 has no magnetic force; at the moment, under the action of the dead weight and the repulsive force between the upper magnetic disc 3 and the first magnetic disc 8, the yarn barrel 2 enables the friction disc 6 on the lower end face of the lower magnetic disc 4 and the friction disc 6 on the upper end face of the electromagnetic disc 5 to be in contact with each other, and the rotation resistance is formed between the two; this resistance is the yarn tension.

When the tension of the yarn needs to be adjusted, the resistance between the two friction discs 6 can be indirectly adjusted only by adjusting the nut 11 so as to adjust the repulsive force between the upper magnetic disc 3 and the first magnetic disc 8, and finally the tension is adjusted.

The mode is suitable for the condition that the tensioner is not needed, the rotating speed of the yarn coil is low, and the tension of the yarn can be adjusted by adjusting the resistance of the yarn coil during rotation.

When high-speed rotation is needed, the electromagnetic disc 5 needs to be started at the moment, and the current and voltage of the electromagnetic disc 5 are adjusted through the controller 10, so that the repulsion force generated between the electromagnetic disc 5 and the lower magnetic disc 4 is enough to support the whole yarn roll; at the moment, the yarn coil can be in a suspended state, namely, the upper end and the lower end of the yarn coil cannot bear friction force, so that the resistance of the yarn coil during rotation is reduced, the noise is reduced, and the abrasion of yarns is avoided.

After the yarn on the yarn bobbin 2 is gradually reduced, the gravity of the yarn roll is reduced, at the moment, the yarn roll can gradually move upwards slightly, but due to the mutual repulsion force of the upper magnetic disc 3 and the first magnetic disc 8, a space still can be left between the upper magnetic disc 3 and the first magnetic disc 8, and the stable rotation of the yarn roll in the whole process is realized.

This is suitable for high speed rotation, and requires additional tensioners for assistance since the yarn package is free of tensioners.

The device can be used by removing the tensioner on the low-speed two-for-one twister as required, so that the abrasion of the tensioner on the yarn is avoided, the resistance of the yarn coil can be adjusted when the yarn coil rotates by screwing the nut 11, the tension of the yarn is adjusted, and the yarn cannot be abraded.

This device can also tell when rotating at the yarn book, through making 5 circular telegrams of electromagnetic disc, and then make whole yarn book be in the state of suspension, has reduced the resistance when the yarn book rotates, is favorable to avoiding the unexpected wearing and tearing of noise and yarn, has realized the stable high-speed rotation of yarn book.
