Common problems with opening width stereotypes
1. Edge and needle loss
Reasons:
①The cloth feeding cart is placed in an incorrect position
②The cloth feeding tension of the front car is not adjusted well, and the overfeed amount is too small.
③The fabric feed edge suction device is not adjusted properly
④The needle plate falls off
⑤The round brush does not work
⑥Vehicle speed Too fast
⑦The width of the gray fabric is too narrow
⑧The photoelectric tracker on the edge of the fabric is not properly adjusted
⑨The upper and lower air volumes are not properly adjusted
Preventive measures:
①The cloth cart should be placed on the center line before finalization
②Adjust the cloth lever to make the gray cloth tension appropriate and increase the overfeed amount.
③ Pay attention to the position of the edge suction device and adjust it in time if any deviation is found.
④ Inspect and replace in time
⑤ Press down the brush and replace it in time if the brush is damaged.
⑥Reduce vehicle speed
⑦Reduce finished product width
⑧Skilled operation Adjust the appropriate position
⑨ Check and adjust
2. Wide edge
Reason:
①The edge suction device is not adjusted properly
②The fabric edge photoelectric tracker is not adjusted properly Good
③The overfeeding amount is too large
④The width of the gray fabric is too wide
Preventive measures:
① Pay attention to adjusting the position of the edge suction device in time
② Adjust it to the appropriate position
③Reduce overfeeding amount
④Increase finished product width
3. Tear the fabric
Reasons:
①There are big holes in the gray fabric or the fabric is easy to detach.
②The setting frame is too wide
Preventive measures:
①Sew the large hole before shaping
②Adjust the shaping process
4 , ruffles
Causes:
①The needle plate is missing or the needle plate is missing.
②The cloth feed is biased to one side
③The overfeed amount is too large or too small
④The door width is too wide and needle insertion is difficult.
⑤The edge detector fails
⑥When feeding the cloth, there is a bilateral phenomenon.
Preventive measures:
①Replace the needle plate
②Front car The cloth feeding should be centered
③The cloth feeding tension should be adjusted appropriately
④Adjust the tenter width
⑤Adjust the edge detector
⑥ Use the air blower of the edge suction device to spread the cloth.
5. Latitude oblique
Cause:
①The feeding fabric is skewed
②The weft adjustment is not adjusted properly
③When sewing the head, the horizontal lines are not straight.
④The elasticity on both sides of the gray fabric is inconsistent
⑤The stitching on both sides of the gray fabric is inconsistent, and the seam head of the gray fabric is skewed.
Preventive measures:
① Feed the cloth correctly
②Adjust the weft adjustment device to correct the weft deviation.
③The sewing head must be straight
④Adjust with the weft straightening device
⑤ Master the operation correctly
6. The width is unqualified
Causes:
①The amplitude modulation is inaccurate or the width specification is wrong
②The temperature is low, the fabric speed is fast, and the fabric does not meet the process requirements, and the fabric is not fixed.
③The fabric itself has wide or narrow width due to quality reasons
④The shaping effect is not good
Preventive measures:
① Adjust the tension and overfeeding amount to be uniform, appropriate and stable.
②Control the width of the processed fabric or adjust the shaping process
③Re-evaluate the weight of the finished product
7. Reasons for unqualified shrinkage rate
① Small overfeeding amount, large tension, and fast vehicle speed ,Low temperature.
②Inaccurate amplitude modulation
③The width and weight of the fabric itself.
Preventive measures:
① Increase the overfeeding amount, reduce the tension, reduce the vehicle speed, and increase the temperature.
②Adjust the width and check frequently
③Re-evaluate the width and weight.
8. Color change
Cause:
①Dye sublimation
②The setting temperature is too high
Preventive measures:
① Use dyes with good sublimation fastness when dyeing dark colors
② Reduce the setting temperature
9. Wind seal
Reason:
①The dye sublimation fastness is poor and it encounters parking problems.
②Stop the fan when parking is useless
Preventive measures:
①Choose dyes with good sublimation fastness
②Connect the hot air motor transmission system in series</p
