Description

Bobbin winder for yarn making

Technical Field

The invention relates to the field of textile machinery, in particular to a winding machine.

Background

In the yarn production process, generally, thinner monofilaments are produced firstly, then the monofilaments are twisted to form thicker yarns, and the produced monofilaments or yarns need to be wound on a bobbin firstly in order to move the monofilaments or yarns and avoid knotting of the monofilaments or yarns. For the convenience of sale or subsequent weaving, the monofilaments or yarns on the bobbins need to be wound on a large-capacity winding roller by using a bobbin winder, and the defects on the surfaces of the monofilaments or the yarns are removed simultaneously in the winding process.

The cone winder is the professional equipment of textile industry, generally include the frame, drive arrangement, the pivot, wind-up roll and a plurality of spool, in order to raise the efficiency, generally can follow a plurality of spools of axial installation in the pivot, because the weight of spool is great, the pivot can take place bending deformation gradually in long-time use, and when the spooling, drive arrangement drive pivot is rotated and is realized the rotation of spool, thereby loosen the yarn, nevertheless after the pivot takes place bending deformation, install the axis of the spool of rotating epaxial and the axis of pivot no longer coincide, the spool can't the even yarn that relaxes in the rotation process, when the speed that the spool loosened the yarn slowed down, the yarn can receive the pulling force of wind-up roll and easily split.

The specific implementation process is as follows:

firstly, manually sliding one supporting cylinder 3 onto the rotating shaft 1, then fixing the fixing block 36 on the rack by using bolts, so that the supporting cylinder 3 cannot move relative to the rack, then sequentially sliding the supporting cylinder 3 into the spool 2 and the next supporting cylinder 3, installing the supporting cylinders 3 and ensuring that the supporting cylinders 3 are arranged on two sides of the spool 2. When the conduit 2 is installed, the end of the support cylinder 3 is slid into the annular groove 21. And slides the slide bar 31, and the slide bar 31 is mounted on the support cylinder 3 using bolts.

After the spool 2 is installed, the thread end of the yarn 6 wound outside the spool 2 is manually pulled and fixed on the winding roller after passing through the guide channel. When winding, the loosening motor, the guiding motor and the winding motor are opened, the loosening motor drives the rotating shaft 1 to rotate, the push plate 13 pushes the blades 23 to rotate, so that the spool 2 is driven to rotate, the yarn 6 on the spool 2 is loosened, the guiding motor drives the two guide wheels 5 to rotate, the yarn 6 is guided, and the winding motor drives the winding roller to rotate to wind the yarn 6 on the winding roller.

Since the slide rod 31 is mounted on the annular plate 35, the slide rod 31 and the slide block 32 cannot rotate, and when the spool 2 rotates, the slide block 32 slides along the curved groove 22, causing the spool 2 to reciprocate left and right. When the line pipe 2 moves leftwards, the right end of the supporting cylinder 3 positioned at the left side of the line pipe 2 extends into the annular groove 21 at the left end of the line pipe 2; when the line pipe 2 slides to the right, the left end of the supporting cylinder 3 positioned at the right side of the line pipe 2 extends into the annular groove 21 at the right end of the line pipe 2, so that the supporting cylinder 3 can always support the line pipe 2.

When conduit 2 rotates, blades 23 cause the gas on the right side of conduit 2 to flow to the left side of conduit 2, so that the gas pressure in support cylinder 3 on the left side of conduit 2 increases, the gap between annular plate 35 and rotating shaft 1 is smaller, and more gas passes through the conduit from gas outlet 33 into cavity 55. The pressure between the yarn 6 and the closing ball 54 on one side is increased during sliding along the guide groove 51, so that the closing ball 54 slides into the air outlet channel 52, the air in the cavity 55 on the side flows out of the air outlet channel 52 to flow between the yarn 6 and the guide groove 51, the sliding of the yarn 6 is lubricated, the friction force between the yarn 6 and the guide groove 51 is reduced, and the yarn 6 is prevented from being broken.

After the winding is finished, the loosening motor, the guiding motor and the winding motor are manually closed, the coil wound on the winding roller is taken down, and the supporting cylinder 3 and the spool 2 are sequentially taken down.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make various changes and modifications without departing from the concept of the present invention, and these should be construed as the scope of protection of the present invention, which will not affect the effect of the implementation of the present invention and the utility of the patent. The techniques, shapes, and structural parts, which are omitted from the description of the present invention, are all known techniques.
