1、 Installing the clothing wrapping machine
1. Adjust the sliding rod so that the sliding rod is parallel to the axis of each cylinder.
2. Adjust the 0.1-0.2mm gap between the side pressing plate and the cylinder surface.
3. When making the above two adjustments, the tension frame shall be pushed to check the same position at the two ends of each cylinder.
Two. Raw Head
1. Grind the starting end of the needle cloth to a uniform inclined surface with a thickness of 0.15-0.2mm.
2. Pass the needle cloth saw blade through each guide wheel on the tension frame, and the front end shall be close to the inner side of the edge strip, and the tension shall be adjusted properly.
3. Confirm that the needle point direction and the winding direction of the needle cloth are consistent with the drawing.
4. Rotate the cylinder slowly to make the needle cloth cover about 10 mm in width. Use flat iron to gently tap from the side to make it tight. At this time, tap a piece of leather strap at the beginning to prevent the needle cloth from loosening.
3、 Wrap volume operation
1. Wrapping speed: wrapping speed should not be too fast, which is easy to cause malpractice such as uneven wrapping and poor smoothness of needle cloth. The normal wrapping speed should be strictly controlled at v ≤ 80m / min.
2. Wrapping tension: in order to prevent the concave deformation of the middle part of the barrel when wrapping the needle cloth, the tension shall be adjusted to 7-8kg within the range of 80mm from both ends of the barrel, and the tension adjustment shall be gradually increased or decreased, gentle and excessive.
3. Welding of needle cloth saw blade: after the needle cloth saw blade is disconnected, the metal needle cloth welder shall be used for butt welding, tempering treatment and filing.
4. All pulleys on the tension frame of the coiler shall rotate flexibly, add lubricating oil frequently and keep clean.
5. The side pressing plate in the coiling shall not be loose, skewed or friction with the roller surface, and the separation distance shall not be too large. The edge of the side pressing plate and the surface of the cylinder body shall be kept clean to prevent dirt from getting into the saw blade of the needle cloth and causing the needle cloth to bulge or have a gap.
6. In the process of wrapping, it is necessary to frequently move the needle cloth striping disc holder, keep the striping disc in line with the guide wheel and the side pressing plate, and prevent the saw blade from touching the edge of the clamping disc. Clean the needle cloth pad paper in time to prevent the pad paper from being brought in, and keep the operation site clean.
7. In the process of wrapping, it is necessary to often pay attention to lowering the side pressing plate and hanging bracket, and the lifting bracket shall not be more than 100mm from the ground, so as to prevent the side pressing plate from jumping out and scratching the surface of the needle cloth too much. When landing, it is necessary to prevent the pressure loss of the elevator landing.
8. Pay attention to the working condition of the coiler and the surface of the needle cloth. Stop the coiling and adjust it in time in case of any abnormal condition or any defect such as inverted needle or loose arrangement on the surface of the needle cloth.
9. When stopping for troubleshooting (or other needs), knock on the leather Block on the surface of the needle cloth, and put down the side pressing plate hammer to ensure safety. The leather block shall knock towards the tooth tip of the saw blade to make the leather tight. Otherwise, not only the leather block is not tight, but also the surface of the needle cloth is concave.
10. Pay attention to observe the needle cloth plate during the process of wrapping the needle cloth. If the needle cloth is not arranged in order or abnormal situation is found, stop wrapping immediately and handle it.
11. Ending: when the needle cloth is wrapped to the end and the side pressing plate is close to the edge strip, the wrapping speed shall be slow. When the side pressing plate contacts the edge strip, it shall stop. Remove the side pressing plate and slowly wrap until the saw blade contacts the edge strip. Then use a flat chisel to tap the needle cloth saw blade and squeeze it into the gap with the edge strip to ensure that the needle cloth is tightly pressed with the edge strip.
12. After wrapping all kinds of needle cloth, grinding is not allowed. If there are local high needles, they can be treated by hand grinding with oilstone.
13. The starting end and ending end of the needle cloth shall be brazed (note that the width of the saw blade shall be ≤ 1.35mm, and tin welding shall be used). The weld bead shall be 20-60mm long, and the oxide skin and dirt on the side surface outside the saw blade shall be removed and a small amount of solder paste shall be applied to avoid embroidery.
14. The start and end shall be firmly welded, and several more points shall be welded in the middle without seeing the size of the cylinder. The welding point shall not be higher than the tip of the needle, and the weld bead shall be polished smooth.
15. Apply talcum powder after passing the inspection.
