Description

Tension device for loose winding machine

technical field

The utility model relates to the technical field of textile machinery, in particular to a tension device of a loose winding machine.

Background technique

At present, most of the yarn tension control of the loose winder on the market adopts the combination of the tension plate and the balance cylinder. This way of controlling the yarn tension cannot achieve the consistency of the yarn tension, especially when making coarse yarns. In addition, when the package yarn (thread) with a larger weight is fixed, the phenomenon of poor package yarn formation is prone to occur, resulting in unqualified products. Under the current conditions, when making coarse-count yarn, the tension of the yarn is usually adjusted manually, that is, according to the length of the yarn winding, the number of tension pieces is manually increased or decreased to ensure the consistency of the yarn tension and the package yarn This method is very cumbersome. Usually, a bobbin needs to adjust the number of tension sheets several times to obtain a bobbin with good winding shape and uniform density. Although qualified products can be obtained by doing this, it greatly increases the number of operators. The labor intensity seriously affects the production efficiency.

The utility model adopts the following technical scheme: a loose winding machine tension device includes a central shaft 1, an upper tension disc 2, a lower tension disc 3, an electromagnetic coil 4, a support frame 5, a push rod 6, a magnet 7, and a single spindle control 8, plastic round parts 9, frame 10, guide rod 14; the electromagnetic coil 4 is circular, fixed on the support frame 5 by bolts 11, and connected with the single spindle controller 8; the support frame 5 is connected by bolts 12 is fixed on the frame 10; the push rod 6 passes through the guide rod 14, the lower end of the push rod is welded with the upper tension disc 2, and a plastic round part 9 is connected to the upper end; the guide rod 14 is fixed on the On the support frame 5; the central shaft 1 is fixed on the frame 10; the upper and lower tension discs 2, 3 are installed on the central shaft.

Further, a blind hole is opened inside the electromagnetic coil 4 .

Further, a magnet 7 is embedded in the plastic circular part 9 and placed in the electromagnetic coil 4 .

Further, the central shaft 1 is made of stainless steel, and the surface is hard soldered.

Further, the single-spindle controller 8 is a single-chip microcomputer installed on the frame 10, and an external Hall sensor is used for measuring and recording the winding length of the yarn.

Further, the upper and lower tension discs 2 and 3 are made of steel, the surface is hard-plated, and the middle is opened.

Further, a hole is opened at one end of the guide rod 14, and a copper sleeve is embedded in the hole, and the copper sleeve is made of oil-impregnated copper material.

Beneficial effects of the utility model: the utility model realizes the setting of multi-segment yarn tension by using a single-chip microcomputer to control the electromagnetic coil. Generally speaking, different pressures are set at different sections of the same package yarn to achieve the tension of the entire package yarn. The tension of the yarn is consistent, and the bobbin with good winding and uniform density can be obtained. At the same time, the automatic control method greatly reduces the labor intensity of the operator and improves the production efficiency.
