9100 Model Air Jet LoomStable Operation
Aug 21, 2017

The 9100 air-jet loom is mainly used for weaving fabrics such as cotton, wool, hemp and silk, which are made of short fiber as raw material. It is suitable for weaving of 4.8tex ~ 233tex staple fiber and 16.6dtex-1350dtex filament fabric. As a result of the throttle design, reducing the energy consumption of the machine, to reduce the operating costs of textile mills have a very good effect.

Performance characteristics

1.FDP-A Ⅲ type electronic control drum storage device

9100 air-jet loom equipped with FDP-A Ⅲ-type electronic control drum storage device, the original length of the device more than about 3 times the amount of ready to roll; with high-speed tracking performance, which can be actively yarn yarn The mechanism is suitable for a variety of weft structures, which can be woven with pure wool and various other yarns. In the high-speed operation and wide weaving, even in the weft is vulnerable to damage conditions, but also rarely occur weft, to achieve a stable operation.

2. High speed, low vibration

Selection of high response speed of the solenoid valve, opening time, closing time of 3ms ~ 4ms, to adapt to loom high-speed operation. Through the finite element analysis of the force, the design of a robust frame structure. The beating mechanism was redesigned with an inertia momentary eccentric beating center, so that the gap was reduced from the original 16mm balance block to only 4mm, thus achieving a good balance of the beating. The use of light alloy hollow steel racade, vibration has been controlled, so that the ground vibration than the original model reduced by about 35 percentage points.

3. Weft control is accurate

Each of the two auxiliary nozzles equipped with a valve to change the original model of a solenoid valve to control the pattern of four auxiliary nozzles, shortening the airway opening time, thereby further improving the high-speed adaptability, so that the air injection more accurate.

4. Air consumption is reduced

A solenoid valve to control the two auxiliary nozzles and auxiliary nozzles and gas cylinders between the shortening of the pipeline, the air consumption than the original model cut by about 10 percentage points, which is a model of innovation.

5. Weft insertion process adjustment is convenient

For different types, different number of weft yarns, not only can adjust the set value of the main nozzle, but also the auxiliary nozzle injection angle is set, in order to achieve stable operation, save energy and improve the quality of the fabric has made contributions. When the loom is started and the weft arrival time is greatly changed, the injection angle of the auxiliary nozzle can be increased, so that the weft insertion is in a stable state and the high quality of the fabric quality is ensured.

6. Beat stability

Due to the use of a four-link beating mechanism in a narrow loom, a six-link beating mechanism is used in the wide loom to achieve stable weft insertion so that the weft is accelerated under low pressure without causing weft damage.

7. Use electronic openings

Electronic opening mechanism, each section of the heald frame and an AC servo motor connected to the AC servo motor cleverly arranged (patent), through the tank gear slowdown, drive connecting rod driven heald frame movement. The electronic control system can control the motor up and down to control the heel frame movement, the electrical box is separated, divided into two layers inside and outside, the inner layer control board, the outer installment servo motor drive package, 16 frame with 16 motors. Electronic opening device has the advantage of being able to freely set the heel angle and phase angle of each frame on the loom. The problem is that the servo motor is more expensive than the general electronic arm, and the opening of the heald frame (more than 16 pieces Heel) movement, the motor arrangement has a certain degree of difficulty. The position line from the original 5 ° tilt into 0 °, so that the upper and lower openings balance, reducing the weaving angle, from the original 14 ° to 9 °, weaving mouth to reduce, more stable.
