Precautions in the process of wrapping metal needle cloth

I. Installing card clothing wrapping machine

1. Adjust the slide bar so that the slide bar is parallel to the axis of each cylinder.

2. Adjust the gap between the side pressure plate and the surface of the cylinder by 0.1-0.2mm.

3. When making the above two adjustments, the tension frame should be pushed to check that the positions are consistent at the two ends of each cylinder.

Twenty-two.

1. Trim the starting end of the card clothing into a uniform bevel, and the thickness of the head is 0.15-0.2mm.

2. Pass the card clothing saw blade through the guide wheels on the tension frame, and the front end should be close to the inner side of the side strip to adjust the tension to be moderate.

3. Make sure that the direction of the needle point of the clothing and the winding direction of the clothing are consistent with the drawing.

4. Slowly rotate the cylinder to cover the clothing with a width of about 10mm. Use a flat iron to gently hit it from the side to make it tight. At this time, you can knock a piece of leather at the beginning to prevent the clothing from loosening. .

三. Packing operation

1. Wrapping speed: It should not be too fast. Too fast speed can easily cause ill-wrapping, poor flatness of card clothing, etc. The normal wrapping speed is strictly controlled at V≤80m / min.

张力 2. Wrapping tension: In order to prevent the middle of the barrel from being deformed when the card clothing is wrapped, the tension should be adjusted to 7-8Kg within a range of 80mm from the two ends of the barrel.

3. Welding of card clothing saw blades: After the card clothing saw blades are disconnected, a metal card clothing welder is required for butt welding, tempering treatment and file repair.

4. Each part of the tensioner of the wrapper should rotate flexibly, and it is necessary to frequently add lubricating oil and keep it clean.

5. There must be no looseness, skew, friction with the surface of the drum, and excessive distance between the side pressure plate in the wrapping. The knife edge of the side pressure plate and the surface of the cylinder should be kept clean to prevent the dirt from being caught in the clothing saw blade and causing the clothing to be raised or have gaps.

6. During the wrapping process, it is necessary to frequently move the card clothing retracting tray holder to keep the retracting tray in line with the guide wheel and the side pressure plate to prevent the saw blade from hitting the edge of the chuck. Clean the card pad paper in time to prevent the septum paper from being brought in and keep the job site tidy.

7. During the wrapping process, you should always pay attention to the drop of the side pressure plate suspension, the height of the suspension is generally not more than 100mm from the ground to prevent the card surface from being scratched too much when the side pressure plate jumps out. When landing, prevent the drop of pressure from the landing gear.

8. Pay close attention to the working condition of the wrapper and the surface of the clothing. If you find any abnormalities or defects on the surface of the clothing, such as inverted stitches or improper arrangement, stop wrapping and adjust it in time.

9. When the parking process fails (or other needs), knock the cowhide piece on the surface of the card clothing and lower the side pressure plate weight to ensure safety. Not only is the leather strap not tight, but the surface of the clothing will be knocked down.

10. Pay attention to the card clothing disk during the process of wrapping the card clothing. If you find that the card clothing is not aligned properly, or if there is an abnormal situation, stop wrapping and handle it.

11. Closing: The card clothing is wrapped to the tail end. When the side pressure plate is close to the side strip, the wrapping speed should be slow. When the side pressure plate contacts the side strip, stop it. Stop the side pressure plate and slowly wrap it to the edge of the blade So far. Then use a flat ladle to tap the card clothing saw blade into the gap between the card clothing and the side strip to ensure that the card clothing and the side strip are tight.

12. After wrapping all kinds of card clothing, it is not allowed to grind. If there are local high needles, you can use the method of manual grinding with whetstone for processing.

13. The beginning and end of the clothing are brazed (note that the blade width ≤ 1.35mm is soldered), and welded to the side strip and the cylinder. The bead length is 20-60mm. When soldering, the outer side of the blade should be scraped Apply a small amount of solder paste on the oxide scale and dirt to avoid embroidery.

14. Be sure to weld firmly at the beginning and the end. Weld a few more points without seeing the size of the barrel in the middle. Weld on the side strips and the barrel. The welding point must not be higher than the tip of the needle.

15. Apply talcum powder after passing the inspection.
