2. Primary adjustment
In order to use the machine more safely and efficiently, do the following checks and primary adjustments before using the machine.
(1) Motor drive inspection
After connecting the power supply, please be sure to check the driving direction of the motor immediately. If the driving direction of the motor is different from the direction shown on the label on the motor housing, the wiring of the motor must be changed immediately (the two phases in the three phases can be switched in the motor junction box).
(2) Check and adjust the motor drive belt
Before the machine works, please check the tension of the motor drive belt and the pressure exerted on the middle section of the belt. At this time, the linear deformation of the belt should not be greater than that. If it is too loose or too tight, it should be adjusted immediately until the requirements are met. The adjustment method is as follows: loosen the fixing screw of the motor base, move the motor outward or inward, and lock the screw after the tension is adjusted to the requirement.
Note: After the initial operation for three days, it should be rechecked, and then it should be checked every three months.
(3) Adjustment of dust blowing system
The fan of the dust blowing system should make specific adjustments to make the fan in the best position so that it can be blown into every corner of the yarn after it is energized and rotated.
(4) Adjustment of yarn feeding transmission system
A Fine adjustment of aluminum plate for yarn feeding
Adjusting the diameter of the yarn feeding aluminum plate can fine-tune the transmission speed ratio and change the yarn feed. The adjustment method is as follows:
First, loosen the round nut on the top of the yarn feeding aluminum plate with a wrench. When the upper surface cover is rotated in the direction of "", the 12 sliding blocks inside the aluminum plate will expand outward, increasing the diameter of the wheel body, thus increasing the yarn feeding amount. On the contrary, when the upper surface cover is rotated in the direction of "-", the sliding blocks will be retracted inward, the wheel diameter will be reduced, and the yarn feeding amount will also be reduced. During the rotation of the cover, it should be kept parallel, otherwise, the slider may fall out of the groove.Adjustable diameter range of aluminum feed plate is: 70mm-200mm. After adjusting the aluminum plate, re-lock the round nut. After the yarn feeding aluminum plate is slightly adjusted, the tension of the yarn feeding transmission belt shall be adjusted.
B. Tension adjustment of yarn feeding transmission belt
If the transmission belt is too loose, the yarn storage device will slip and stop, which will affect the yarn feeding. Therefore, the following adjustments should be made to the yarn feeding transmission belt before starting the machine:
Loosen the roller fixing screw and pull the roller outward along the sliding rod. At this time, the belt should be evenly stressed on the whole circle of yarn storage. Locking screw.
(5) Inspection of grease lubrication
Check the lubrication of various parts of the transmission system and cloth rolling system, and supplement grease lubrication every day to avoid wear caused by lack of grease lubrication.
