Machine adjustment and maintenance Machine adjustment
1. Feeding adjustment
Adjusting the two adjusting bolts behind the rear casing plate can change the gap between the rear casing plate and the feeding roller and control the amount of feeding.
The feeding amount is directly controlled by the speed of the feeding roller. The tightness of the cotton roll in the working box is reflected by the different forces exerted on the density board. The sensor can convert this information into an electrical signal and feed it back to the speed-regulating motor in a timely manner. The speed of the speed-regulating motor determines the speed of the feed roller. Rotating speed. This system automatically adjusts and controls the feeding amount according to the tightness of the cotton roll.
2. Cotton roll density adjustment
Adjust the upper and lower positions of the limit block, that is, change the two extreme positions of the density board and adjust the position or weight of the balance block on the rod, that is, change the balance moment of the density , can change the tightness of the cotton roll density in the work box; turn the eccentric adjustment wheel or change the position of the hook screw of the holding plate and adjust the distance from the cotton grid to the ribs, you can change the cross-sectional area of the work box or the size of the row. Adjust the processing capacity and velvet yield of the velvet stripping machine.
3. Adjustment of the distance between the plectrum roller and saw blade tooth tip
Adjustment of the position of the saw shaft, the up and down position of the support adjustment seat under the work box, the length of the positioning bolts on the work box, and the adjustment of the hanger bolts can all be used The distance between the plectrum roller and the blade tip is changed. But no matter which method is adopted, it must be ensured that the saw blade is in the correct position, the work box is flat, and the spacing meets the requirements.
4. The wind speed of the velvet suction port
The wind speed of the velvet suction port is adjusted to 8~12m/s.
5. Sensor zero adjustment
(1) Start the feeder motor, turn on the power of the manipulator, check whether the density meter has a ±5V output (normally it should), and check whether the connection between the sensor and the density meter is correct ( Red is connected to +15V, green is connected to -15V, black is connected to ground, and white or yellow is connected to signal output).
(2) Adjust the lever on the density axis to the low position and see if the density meter indicates whether it is at the zero point. If not, adjust the zero point 103 (10kΩ) potentiometer and move the zero point counterclockwise in the positive direction until it corresponds.
(3) Adjust the density board to the high position and check whether the density meter indicates whether it is at the 100kg position. If not, adjust the amplification signal 503 (50kΩ) potentiometer and increase the amplification counterclockwise until it corresponds or is connected. .
6. Adjustment of the inclination of the travertine plate
Adjusting the position of the support under the travertine plate and changing the inclination of the travertine plate can change the position of the cotton seeds entering the work box.
After the machine is adjusted, it must be tightened and the saw blade roller shaft and other rotating parts must be turned by hand. The parts should be sensitive and reliable, and no friction or collision sounds are allowed.
