New Breakthrough Of Domestic Gauze Finishing

< p > by the Wuxi Feida textile printing and Dyeing Machinery Co., Ltd. successfully developed and marketed the MHF992 efficient and energy saving medical gauze drying and cutting joint machine.

The combined machine technology is advanced, bold and innovative, and has reached the international advanced level of contemporary similar equipment. It has ended the history of domestic production equipment which can not produce high-grade gauze, and has filled the gap in the domestic market.

< /p >

< p > in recent years, with the wide application of medical a href= "http://www.91se91.com/news/index_c.asp" > gauze < /a >, the market demand at home and abroad is bigger and bigger.

However, the technical content of processing and finishing equipment for medical textiles is not high. Most products are inefficient, energy consuming and unable to continuously produce.

Wuxi Feida textile machine seized the opportunity of upgrading this industry, started with the pformation of the traditional finishing equipment of the medical gauze industry, and discussed with the technicians of Hubei Zhijiang Ogilvy medical supplies company. Through technical improvement and technological innovation, it tried to solve the shortcomings of the old machine, such as slow speed, low efficiency, high energy consumption, poor quality, and high labor intensity.

< /p >

< p > in the general train of thought, the single machine rewinding, single machine drying, < a href= "http://www.91se91.com/news/index_c.asp" > single machine < /a > cutting are combined to improve the grade of the processing gauze, reduce the energy consumption and labor intensity of the equipment, and greatly improve the production efficiency.

At the same time, the new technology of energy saving, environmental protection, computer data exchange of IPC has been widely infiltrated in the design process of the combined machine.

In the design process, we use the unwinding device, tension control, edge sucking device, dryer drying, stainless steel guide roller, dryer drying, tension control, high precision automatic correction device, pressure cutting and cutting device, -A/B coil surface misalignment device.

< /p >

< p > the machine adopts a new type of unwinding device, which can ensure that the machine is stable at high speed.

In this process, the machine uses the pressure changing cylinder pressure device and the stable tension sensor.

In the drying part of the drying cylinder, a two variable frequency reduction motor is used to drive 12 stainless steel drying cylinders, and the decelerating motor is controlled by a frequency converter.

The shaft of the baking cylinder is connected with the double row sprocket by a conical sleeve to ensure the matching effect between the axle head and the pulley when the dryer is running at high speed. The cylinder bearing adopts a heavy roller bearing, and an automatic filling pump is used for centralizing the fuel, thereby effectively improving the convenience of the equipment maintenance.

< p > before the a href= "http://www.91se91.com/news/index_c.asp" > gauze < /a > cutting, the Italy RE automatic high precision process side alignment control system is configured. The system contains control box, photoelectric sensor, driver, mounting bracket and actuator, which is suitable for the high speed (300 m / min) state of the opposite side.

The cutting and cutting device is equipped with 11 cutter positions. Each pneumatic cutter is equipped with a pneumatic crushing knife and a pneumatic cutter. The bottom knife roller and the A/B coiling roll are driven by a variable frequency decelerating motor (encoders). The material is made of 38CrMoAl high alloy steel, the surface is ionized, the surface hardness of the roller is more than HRc67, high surface hardness, high wear resistance and high fatigue strength; the broken knife and the slitting knife are manually moved.

< /p >

< p > misalignment is used for surface rolling after slitting. It prevents the coils from being interlocked and the maximum diameter of the take-up is 800 mm.

This machine adopts frequency converter and PLC control, and has the function of single action adjustment and whole machine linkage. The speed of the whole machine can be lifted up and down linearly, so that the tension is constant and the line speed is stable.

The tension control device is adopted. The tension controller is adopted to ensure the constant tension of the servo unit, and the whole machine adopts high-performance vector converter plus encoder to make closed loop control for each AC drive unit, so as to ensure the line speed of each unit is consistent.

In addition, the machine also has data collection, quantization, storage, data networking, and reservation printing interface.

< /p >

< p > MHF992 energy efficient medical gauze drying and cutting combined machine has advanced technology, reliable performance and low energy consumption. It also meets the high quality requirements of finished gauze with uniform density, good quality, good drapability, good handle, environmental protection and no pollution. It has good economic and social benefits. It won the three prize of 2013 science and technology progress of Heng Tian Group and the high and new technology product award of Jiangsu.
