In order to use the circular knitting machine more safely, do the following inspections and preliminary adjustments before using the machine.

1. Motor drive inspection

After connecting to the power supply, be sure to check the driving direction of the motor immediately. If the driving direction of the motor is different from the direction indicated on the label on the motor housing, you must immediately change the wiring of the motor (connect two of the three phases in the motor junction box). can be adjusted).


2. Inspection and adjustment of motor drive belt

Before starting the work, please check the tension of the motor drive belt, and apply a pressure of 1-1.8kg to the middle of the belt. At this time, the linear deformation of the belt should not be greater than 3.5mm. If it is too loose or too tight, it should be adjusted immediately until it meets the requirements. Adjust The method is as follows: Loosen the fixing screw of the motor base, move the motor outward or inward, adjust the tension to the requirement and then tighten the screw.

Note: After three days of operation, it should be checked once, and then every three months.


3. System adjustment

The fan of the system should be adjusted specifically, so that the fan is in a position so that it can blow to every corner of the incoming yarn after it is powered on and rotated.


4. Adjustment of the yarn feed transmission system

  • Fine-tuning of Yarn Feeding Aluminum Disc

Adjusting the diameter of the yarn feeding aluminum disc can play the role of fine-tuning the transmission speed ratio and changing the yarn feeding amount. The adjustment method is as follows:

First, use a wrench to loosen the round nut on the top of the yarn feeding aluminum pan. When the upper cover is rotated in the " " direction, the 12 sliders inside the aluminum plate will expand outwards, increasing the diameter of the wheel body, thereby increasing the amount of yarn fed. , The diameter of the wheel is reduced, and the amount of yarn feeding will also be reduced. During the rotation of the cover, it should be kept parallel, otherwise, the slider may fall out of the groove. ®The adjustable diameter range of the yarn feeding aluminum plate is: 70mm-200mm. After the aluminum plate is adjusted, re-tighten the round nut. After the fine adjustment of the yarn feeding aluminum plate, the tension adjustment of the yarn feeding transmission belt should be done.


  • Tension Adjustment of Yarn Feeding Belt

If the drive belt is too loose, the yarn storer will slip and stop, affecting the yarn feeding. Therefore, the yarn feeding drive belt should be adjusted as follows before starting the machine:

Loosen the fixing screw of the roller, and pull the roller outward along the sliding rod. At this time, the belt should be evenly stressed on the entire yarn storage. Lock the screw.


5. Inspection of grease lubrication

Check the lubrication of the transmission system and the cloth rolling system and other parts, and replenish the grease lubrication every day to avoid the wear of the parts caused by the lack of grease ubrication.
