DW7090D Twin Screw Carbon Fiber Melt Spinning Machine is designed according to the user's requirements based on the melt spinning process.
It is used for polyester, polyamide and polypropylene fiber melt composite spinning, drawing and winding into cylindrical filament. This machine is an ideal melt spinning teting machine for chemical fiber factories and scientific research institutes. This machine can spin udy or FDY.

How to use this machine and how to maintence . Let us tell you how to do it
Assembling the machine
1) Open the packing cases of equipment components and check equipment condition;
2) Confirm the installation site and clean up the site. Move the lower part of the equipment to install site, adjust the foot to make it even;
3) Use a forklift or crane to lift the upper part of the equipment to a height higher than the lower part. Place the upper part on the lower part according to the direction shown in Figure 1. Adjust the position of the upper part to make all the retaining screw holes are aligned and use a wrench to tighten the retaining screws of the upper and lower parts;
4) Place the waste box on the left side of the equipment. Connect the wired hose between the thread suction gun and the waste box; and connect the transparent hose of the thread suction gun to the air source adapter behind the main machine (See Figure 2 and 3). The other side of the air source adapter is connected to the high pressure air source
2.. Electrical connection
1) Electrical connection between control cabinet and main machine
2). ts and metering pump is slight, it can continue spinning. If it seriously affects the pump capacity and normal spinning, it needs to be tightened or replaced.
3) If the metering pump is stuck, the pump capacity is insufficient or does not produce slurry, the metering pump may be damaged and replaced.
4)If the newly installed metering pump does not work or the shaft head of the metering pump is damaged, it may be that the preheating temperature is not enough or the holding space is not enough. Continue to keep the heat preservation to reach the spinning temperature. Replace the shaft head
5)In normal spinning, the components should be replaced immediately in case of floating yarn and filament.
6)The phenomenon of "slub silk" appears in the new assembly, which may be due to insufficient heat preservation of the module. After a certain period of balance, the spinning can continue.
7)When "raindrop wire" appears in the module, the temperature of the module is too high, and it can return to normal after a certain period of equilibrium.
8)The phenomenon of "injection head" appears in the spinneret hole, which may be due to the unclean edge of the spinneret hole. If the "silicone oil rest" of the spinneret hole with a copper spatula is invalid, the components should be replaced.
9) Cause of hairiness
Insufficient oil, adjust the speed of the tanker
If the spinneret is not clean, silicone oil can be used for rest. If the spinning temperature is too high, adjust the process temperature.
S/N | position | Period | Inspection contents | Problems and Solutions |
1 | Screw reducer | a year | Smooth operation, separate drive wire guide plate whether there is abnormal noise | There are abnormal noises and hairpins. Please replace the bearing or add lubricating oil |
2 | Hot roll parts | Two weeks | Smooth operation, separate drive wire guide plate whether there is abnormal noise | Remove the hot roller (pay attention to the protection surface) and check the bearing condition. There are abnormal noises and hairpins. Please replace the bearing or add grease. |
3 | Power take-off components | half a year | Check the motor for abnormal noise. | Check whether the motor has abnormal sound and stuck. Please replace the bearing or add grease (reducer) |
4 | Winder head parts | Two weeks | Smooth operation, separate drive wire guide plate whether there is abnormal noise | Check the bearing condition. There are abnormal noises and hairpins. Please replace the bearing or add grease. |
