The problems with the human cotton weaving machine are as follows:
1、 The reasons for warp yarn breakage in human cotton weaving machines (excluding the quality of the original yarn and preparation reasons)
1. The height of the comprehensive frame is too high, and the left and right sides are uneven.
2. Opening too big or too small, too early or too late.
3. The warp thread is too short (the back beam passes through the front), and the warp tension is too high
4. The position difference between the rear beam and the warp stop frame is large, and the tension of the upper and lower warp yarns is too high.
5. The distance between the warp stop frame and the heald frame is too far or too low.
6. Air conditioning and humidity too high or too low
7. The sword neck, reeds, combs, warp curtains, sword straps, etc. are rough.
2、 The causes of weft yarn breakage in human cotton weaving machines
1. Low weft strength, loose twist, large knots, cottonseed shavings, and flying wire clips.
2. Excessive strength, tension, and poor forming during winding.
3. When the side bracket is too forward to reach the spring, there should be at least 1mm gap between it and the spring.
3、 Double weft of cotton weaving machine
1. Weft breakage is the main cause. Reduce weft breakage first.
2. The workers on duty did not notice that the weft was broken at the weaving mouth.
3. After breaking the weft, when the weft opening sequence is more suitable than the main weft opening sequence, the shift control will not start.
4. After the weft yarn breaks, the movement of the weft yarn does not immediately stop, and there is either less or less weft in the middle.
4、 Weft Shrinkage of Cotton Weaving Machine
1. Excessive twist in weft yarn.
2. Weft yarn is too dry or too wet.
3. I don't speak clearly.
4. Opening time too early or too late.
5. The tension of the weft insertion is too small.
6. Insufficient warp tension.
7. The weft tube has large knots, flying flowers, foreign objects adhering to it, coarse yarn, and unclear opening.
5、 The Minor Diameter of Cotton Weaving Machine
1. Loose or corroded reeds and take-up rollers.
2. Excessive or insufficient warp tension.
3. The tension between the upper and lower layers of warp yarn varies greatly.
4. When driving after parking for a long time, the car shed is not aligned.
5. Starting too slowly after parking will affect the weaving force (the main motor belt is loose (weak))
6、 Weaving of Weft Tail on Cotton Weaving Machine
1. The right warp yarn is too far away from the lower air duct, and the waste edge yarn is not firmly clamped at the end.
2. The tension of the weft yarn is too low, and the opening time of the rapier head is too late.
7、 Sparse roads
1. The reason is broken weft, reduce the broken weft first.
2. The broken weft winding and unwinding device is faulty.
8、 Jumping Flowers
1. The comprehensive frame is loose, uneven, or too low.
2. There is a significant difference in warp tension between the upper and lower layers.
3. Excessive sizing, sticky opening, and poor sizing can cause lint or fuzz.
4. Warp yarn has flying hair, yarn tails, and large knots.
5. Comprehensive head, comprehensive tail fracture or comprehensive head disturbance.
6. Part of the warp yarn is loose or the tension is too low.
7. Opening time error (opening too small)
8. The height of the side brace is not standard.
9. The spring numbering is too dense. Please check the spring plate number and process table.
10. If there is too much yarn on each spring, please check the process table.
9、 Spider web
1. Menopausal pills have a high density and will not stop immediately after menstrual interruption.
2. The accumulation of flying flowers between menopausal membranes and movement disorders.
