Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of elasticizer, in particular to a high-elasticity cotton ammonia covering yarn elasticizer and its elasticizing method. BACKGROUND

[0002] The elasticizer is a kind of equipment for processing textiles, and its main function is to carry out elastic treatment on fiber materials, so that it has better elasticity and resilience. The working principle of the elasticizer is to use elastic force on the fiber material to make it elastically deform, thereby changing its physical properties. Overall, the elasticizer changes the physical properties of the fiber material by applying elastic force to make it elastically deform, thereby improving the elasticity and resilience of the product. However, when processing silk threads, the silk threads themselves will adhere heat after cooling due to the temperature adjustment speed of the equipment, and when the pressure of the silk threads themselves is too large, the silk threads are prone to breakage. In view of this, we have made technical innovations on the basis of existing manufacturing equipment.

[0043] Further, the use method of the elasticizer for high-elasticity cotton ammonia covering wire comprises the following operation steps:

[0044] Step one: rotate the connecting shaft 26 connected with the winding assembly 4 by 90 degrees through the clamping block 25, insert the collecting sleeve 32 into the inside of the connecting shaft 26, then reset the connecting shaft 26, and re-clamp the connecting shaft 26 and the butt joint support 24;

[0045] Step two: place the wire drum in the unwinding frame 7 inside the unwinding structure 2 in sequence, and connect the wire drum and the unwinding column 28 in sequence;

[0046] Step three: pass the wire in the wire drum through the false twist assembly 5 into the collecting sleeve 32 on the outer surface of the connecting shaft 26 inside the unwinding structure 2 inside the elasticizer main body 1 to fix, and contact the fixed wire with the adjusting assembly 6;

[0047] Step four: drive the wire to rotate by the unwinding structure 2 of the elasticizer main body 1, move the wire in the false twist assembly 5, contact the friction disc 17 of the false twist assembly 5 with the wire, drive the friction disc 17 to rotate by the rotating ring 20 fixed by the rotating rod 19 when the stepping motor 18 of the false twist assembly 5 rotates, and drive the wrapped wire to twist in the rotating process of the friction disc 17;

[0049] Step 6: The docking bracket 24 inside the winding assembly 4 drives the connecting shaft 26 to rotate, and the connecting shaft 26 drives the collecting sleeve 32 to rotate, so that the yarn continuously winds around the outer surface of the collecting sleeve 32. When the yarn is winding, the adjusting assembly 6 adjusts the pressure on the contacting yarn through the internal pressure sensor 31, and drives the barrier column 30 to move through the electric telescopic rod 29.

[0050] Step 7: When the winding assembly 4 has finished collecting the yarn, rotate the connecting shaft 26 by 90° to pull the collecting sleeve 32 out of the connecting shaft 26, so that the collecting sleeve 32 can drive the yarn to collect.

[0051] In summary, as Figures 1-5 As shown, the texturing equipment and texturing method for a high-elasticity cotton-ammonia-coated yarn are used by first rotating the connecting shaft 26 connected to the winding assembly 4 by 90 degrees through the locking block 25, inserting the collecting sleeve 32 into the connecting shaft 26, and then resetting the connecting shaft 26 and locking it back into the docking bracket 24.

[0054] The unwinding structure 2 of the texturing machine body 1 drives the yarn to rotate, and the yarn inside the false twist assembly 5 moves. The friction disc 17 of the false twist assembly 5 contacts the yarn. When the stepper motor 18 of the false twist assembly 5 rotates, the rotating ring 20 fixed by the rotating rod 19 drives the friction disc 17 to rotate.

The wire continues to move downward, and the contact post 2202 inside the wire detection component 22 blocks the swaying of the wire, so that the downward conveying of the wire remains stable.

[0056] The docking bracket 24 inside the winding assembly 4 drives the connecting shaft 26 to rotate, and the connecting shaft 26 drives the collecting sleeve 32 to rotate, so that the yarn continuously winds around the outer surface of the collecting sleeve 32. When the yarn is winding, the adjusting assembly 6 adjusts the pressure on the contacting yarn through the internal pressure sensor 31, and drives the barrier column 30 to move through the electric telescopic rod 29.

[0057] When the collection of the yarn by the winding assembly 4 is completed, the connecting shaft 26 is rotated by 90° to pull the collection sleeve 32 out of the connecting shaft 26, so that the collection sleeve 32 collects the yarn.
