Single Yarn Covering Machine

Equipment overview

HKV141D Spandex/Elastic Yarn Covering Machine (Single Yarn Covering Machine) is suitable for the production of 70D~600D covered yarns of different specifications (covering between nylon, polyester or cotton yarn and spandex). The advantage of low power consumption. Its final products are mainly used in knitting fields such as hosiery, weaving and underwear.

Product Features

1. The machine is equipped with a variety of spindle components of different specifications, including straight and conical spindles. Straight and tapered spindles refer to the inner hole of the outer wire. Generally speaking, straight spindles are mainly suitable for users to produce double-package yarns due to the simple control of winding and twisting direction, while conical spindles are used for dismantling bobbins. It is more convenient, the bobbin and the spindle are well combined, and it is mostly used for the production of single-package yarns. The spindles are arranged in an arc shape to save power consumption.

2. The machine forming box is suitable for covering a variety of different specifications of spandex and outer yarn. Due to the use of oil bath forming box and advanced axial and circumferential anti-folding mechanism, as well as progressive edge closing device, Equipped with a bobbin holder made of steel plate with sufficient strength, the coiled formed bobbin has a smooth appearance and is suitable for unwinding in the next process.

3. The overall welded frame is firm and stable, and the installation is fast and simple, which is completely suitable for the needs of high-speed production.

4. The front part of the car is equipped with a digital display controller, which mainly monitors the speed of the upper and lower spindles, the speed of the take-up roller and the feed roller. The interior adopts domestic advanced electrical components, adopts star-delta delay conversion to start, and has a motor motor air circuit breaker and an overheat protector, which double protects the motor, effectively cuts off the power supply in case of overcurrent, and protects human-machine safety. At the same time, it is equipped with a delayed shutdown function of the lower layer, which can basically ensure the synchronous shutdown of the upper and lower layers, and avoid annoying silk thread summary during shutdown.

5. At the lower end of the machine, there is an active spandex wire feeding part, and the roller can be made of bakelite roller or steel pipe roller, which can effectively ensure the accuracy of the drafting ratio.

6. The front part of the machine adopts two motors to drive the upper and lower spindles respectively, so that the S and Z twist conversion can be quickly realized, especially when processing double-package products, the spindle speed can be adjusted by replacing the pulley. Make sure the inner and outer yarn torsion is balanced.

7. Three sets of matching gears are set at the end of the machine, and the gear matching ratio between each group can be adjusted according to the needs of the yarn to be processed to meet the user's requirements for twist, draft ratio and coiling tightness.

8. The two sides of the machine are respectively equipped with footboards, which can easily disassemble and install the coiling bobbin at any time, which reduces the operating height and improves the work efficiency.

User-selectable components

1. Main motor frequency conversion function: easy to adjust the spindle speed, simple and accurate;

2. Lateral micro-movement device: effectively prevent the pressure roller from grooving and ensure uniform twist.

3. Open forming box: suitable for producing fine denier covered yarn forming.
