[There is a flaw in the maintenance of the double-twisting machine. Have you done it?]

Machine maintenance is an indispensable part of daily production. The quality of machine maintenance directly affects the quality of the product, so the content and standards of maintenance are very important. The following are the parts that the double twister needs to check frequently:


Spindle section

Check the flexibility of the spindle operation:

1. Remove the spindle; 2. Grasp the stationary disk and gently rotate the rotating disk to check if the rotation is flexible? Is there an abnormal noise? Is it lack of oil?

If abnormal spindles are found, they are processed in the following order:

1 Pull out the stationary disc (cartridge binder) to separate the stationary disc from the disc.

2 Check if the spindle bearing is wrapped with waste wire, remove if necessary, and check the flexibility of the bearing.

3 There is no yarn winding, but the bearing rotation is not flexible; or the bearing rotation is still inflexible after removing the yarn, the special bearing is needed to remove the bearing and replace the new bearing.

4 Use a special clamp to hold the inner ring of the bearing and press the bearing.

5 After re-applying the apron on the bearing, press the stationary disc.

If the spindle is short of oil, it should be refueled immediately.


Dragon belt part

Check if the dragon belt has abnormal noise, whether it is swaying up and down, whether it is wrapped with yarn, or whether it is stained with oil.

The abnormal sound of the dragon belt indicates that the operation has been abnormal, or the yarn is wound. To check that the dragon belt does not touch the lowest part of the introduction, if it is necessary to adjust the height of the tensioning guide wheel, adjust from the side of the active belt pulley. When the right hand is turned, the dragon belt rotates clockwise, so start the inspection from the active belt pulley when adjusting, and check it clockwise one week.

The ups and downs of the dragon belt are also caused by the poor position of the tensioning guide wheel. If the yarn is wrapped around the dragon belt, it can be disposed of when it is stopped in a small amount. If it is large, it needs to be dealt with immediately. Otherwise, the dragon belt will slip and abnormal noise will occur.

When the dragon belt is seriously polluted, the spindle speed will decrease, the belt will slip and an abnormal sound will be emitted. Therefore, the belt should be removed and cleaned with a neutral detergent.


Tightening guide wheel

When the belt is driven, the outer side of the guide wheel and the inner side of the belt are tightened. The main function of the tension guide wheel is to maintain the tension of the belt to ensure that the transmission does not slip.

When tightening the guide wheel, make sure that the tensioning guide wheel is flexible. If the tensioning guide wheel is not flexible, it will wear the belt. At the same time, it is necessary to ensure that the tensioning guide wheel drive is stable.

If the dragon belt is too high at this time, you need to adjust downwards. The steps are as follows:

1 Loosen the fastening screw;

2 Loosen and lift the left lifting screw, then unscrew the right lifting screw;

3 Tighten the fastening screws. Generally, the adjustment range of the dragon belt is very small, and the position of the dragon belt on each tensioning wheel is as good as possible.

Double twisting machine refueling situation

Refueling standard, refueling cycle, refueling method, refueling quantity, oil type

Spindle every six months tanker 4.5 spindle oil

In-spindle bearing 18 months Hand wipes Spread even Low-torque high-speed grease (2# oil)

Tightening guide wheel 2 years hand wipe moderate amount of ordinary butter

Worm gear reducer 1 month Oil gun Appropriate amount 320~SS~100 special gear oil

Gear surface, change gear 1 month, hand or grease gun, evenly spread, ordinary butter

Overfeed roller chain forming cam chain rotation and reciprocating parts 1 month Oil gun or brush Evenly spread 100# Lubricating oil

Shifting rod sliding sleeve 3 months Oil gun or brush 2~3 drops 100# Lubricating oil

Twisting gear bushing nozzle Every day Oil gun 4~5 drops 100# Lubricating oil

Refueling is an important measure to reduce mechanical wear. Refueling should be regularly quantified. After refueling, it should be checked frequently to prevent leakage and increase. It is necessary to ensure the need for mechanical lubrication and not to waste oil. Be sure to be hygienic after refueling and keep the machine clean.
