After 22 years of experience in product research and production, Baohua brand drawing frame has won widespread reputation at home and abroad due to its excellent product performance.

Now, the brand has become a banner that Shaanxi Baocheng Aviation Precision Manufacturing Limited by Share Ltd set up in the drawing frame manufacturing field.

Shaanxi Baocheng Aviation Precision Manufacturing Limited by Share Ltd belongs to the first group of China aviation industry. It has the comprehensive ability of developing, developing and manufacturing.

After the technical pformation of the first phase, the two phase and the "double plus" project, Shaanxi Baocheng has formed an annual production capacity of nearly 1000 high speed drawing frames, and the machinery manufacturing equipment and testing equipment are perfect.

Each enterprise has its own business ideas, or horizontal development, product range, or vertical development, refinement of the same product of different adaptability.

Baocheng company is walking along the road of fine product development in the production and operation of drawing frames, and meets the needs of all levels through perfect product design.

In the recently held ITMA ASIA +CITME 2008, we saw the products of the series drawing frame displayed by Baocheng company and felt the efficient idea that runs through every product design.

The FA311 series high-speed drawing frame is stable and reliable, and has wide variety of spun fibers.

The fiber length of FA311A drawing frame is 20~75mm.

The 61~75mm fiber can also be spun. Only third rollers are removed on the craft, and then the upper and lower three guiding rolls and the pressure bar type dual zone drafting can be changed to three, and the maximum output speed can reach 400m/min.

The FA311F high-speed drawing frame is a new drawing frame designed on the basis of the FA311A drawing frame.

A new type of cluster device and a roller type / velvet cloth upper cleaning device are adopted in the drafting area, which is conducive to ventilation and heat dissipation in the drafting area and improving the quality of the strip.

The pmission part adopts a closed oil bath gearbox, all pmission gears are high precision helical gears, the pmission structure is reasonable, the operation is stable, the noise is small, and the synchronization is good.

The electrical part adopts imported programmable logic controller (PLC) to complete the logic control of the machine, with strong anti-interference ability and reliable operation.

Feeding is controlled by microcomputer controlled photoelectric switch. The detection speed is more than 1m/s.

The output speed of FA320A high-speed drawing frame can reach 500m/min, and the main motor adopts variable frequency speed regulation.

Oil bath lubrication, stable gear pmission and low power consumption.

The advanced text display terminal is directly connected with the programmable logic controller (PLC) to process and set up the process parameters.

The FA313B and FA322B series high-speed drawing frames combine the advantages of the similar models at home and abroad. The main engine adopts frequency conversion speed regulator, and the panel adopts microcomputer technology, feeding and installing the missing bar controller, eliminating the missing strip phenomenon, and the output speed is 600m/min.

The FA322B high-speed drawing frame is equipped with a self leveling device and an on-line inspection device.

The fragment 15-20mm is uniform, with a range of + 25% and a precision of <1%.

The equipment performance has reached the international advanced level in 90s and the leading level in China.

The FA313B-600B large coil high drawing frame drawing speed is 600m/min, the maximum output cylinder diameter is 600mm, and the cylinder height is 1200mm, which is a combing pre assembly and air spinning process requirements.

Shaanxi's Baocheng drawing frame has always positioned technological research and development as "high speed".

In the current textile machinery exhibition, the company has introduced a new device - FA1382 single eye high-speed drawing frame.

The equipment is also based on the concept of "high speed", and its main spinning indexes and spinning performance levels have been greatly improved.
