1. Check the polyester spinning machine frequently

Check whether the sound of the transmission part in the front and rear transmission box is normal; whether the timing belt is off-track; whether the bearings of each roller component, friction roller component, thread guide and transmission component are heated and vibrated; whether the top roller has scars; Whether the false twister, the bobbin holder chuck and the top roller rotate flexibly and so on.

2. Regular maintenance of polyester spinning machine

Minor repairs generally focus on cleaning the equipment and check the damage of the running parts and the thread guide. In addition to checking the cleanliness, the overhaul is to check the cleanliness and wear of the timing belts and timing pulleys of the transmission parts; open the slot Wear conditions of cylinders, shuttles, sliders, etc. Maintenance cycle: stop for minor repairs every 2-5 weeks, and overhaul every 1-3 months.

3. Maintenance of the hot box

Because when the thread passes through the hot box tube, the spinning finish on the thread is heated and volatilized, and a small part of the components with lower boiling points remain in the heat pipe. The formed dirt and coking will affect the heating effect of the thread. , Cause the quality of DTY to decrease, so it should be removed regularly. The cleaning cycle depends on the fineness of the processed silk, the operating speed of the machine and the type and content of POY oil, generally 2-3 months. Clean the wire guide tube in the strong heat box regularly. Pull the tube out from above, put it in 15%-20% lye and heat it, take it out after cooling, wash it with hot water, and blow it dry with compressed air to check whether the dirt in the tube is clean. When cleaning the pipe, be careful not to damage the nozzle, inner surface and other machine parts.

The wire guide tube in the second heating box should be cleaned regularly. Turn the heat box to an inclined state, pull out the tube from the top, put it in 15%-20% lye and heat it, take it out after cooling, wash it with hot water, and blow it dry with compressed air to check whether the dirt in the tube is clean. When cleaning the tube, be careful not to fuzz the tube orifice and the inner wall, so as to avoid the damaged tube from wiping the processed thread.

4. Repair of top rollers

The first and second roller top rollers are generally polished once after 1-3 months of use, and the three-roller top rollers are polished once after about 6 months of use. While polishing, check whether the bearing rotates flexibly.

5. Maintenance of friction false twister

It is necessary to remove the waste silk wound on the friction spindle and the "snowflakes" on the friction disk in time. When the friction disk speed is abnormal, the false twist tension is out of adjustment (confirmed to be caused by the friction false twister), and the spinning is difficult, it should be removed. Friction false twister inspection. Check whether the small bearing of the false twister is damaged and whether it rotates flexibly, and whether the small toothed belt that drives the three spindles is elongated or worn. If an abnormality is found, replace it in time.

6. Adjustment of the winding device

If it is found that the winding bobbin is poorly formed, there are windings (winding away from the normal track), sag, and large differences in surface hardness, the winding system must be checked to check whether the winding bobbin is bounced and the traverse guide track is not Correctly wait.

7. Check the elastic coupling

Each time you stop the machine, you must check whether the elastic coupling of each part is loose or worn. If there is looseness, the cause must be fixed. If there is wear, it must be replaced.

8. Check the timing belt

The operation of the timing belt must be checked every day to observe whether there is any looseness, less teeth, and friction between the timing belts.
