Adjustment and application of pneumatic splicer

Shanghai textile technology fabric production = adjustment and application of pneumatic splicer Zhang Suzhen Jiangsu Jiangyin workers 214432 Zhou Qingjiang ç–‹ Red Star Rehabilitation Company 1 foreword, 238 automatic winder set automatic suction head pneumatic splicing automatic tube change and other modern The working environment of the plant changed to reduce the labor intensity, improve the quality and output of the product, and the machine has a wide range of applications. The filament yarn, the spun yarn, the cotton yarn, the polyester yarn, the combed yarn, the carded yarn, the linen yarn, etc. The quality is in line with the subsequent process is the performance and commissioning of the pneumatic splicer.

2 The operation of each mechanism in the process of splicing is matched with the nozzles of the nozzles and the nozzles of the nozzles and the nozzles respectively, and the yarn guide hooks the yarn ends of the tubes, and the yarn ends of the packages are sucked by the large nozzles, and the waveguides are attracted. The yarn hook is pulled into the gutter. In this way, the small nozzle is turned to the highest part, the yarn end of the crepe yarn is pulled into the splicing groove, the yarn clamp clamps the yarn end of the upper and lower sides of the cattle, the scissors cut the yarn end, and the size of the nozzle cuts the yarn. The head is sucked away, the tube is sucked to the end of the two yarns in the splicing groove, the retracting solenoid valve is opened to compress the air, the yarn end is pre-pulled, and the feeding arm and the splicing groove door are turned to the innermost position. The feeding yarn pulls the untwisted yarn end out of the holding tube into the splicing chamber, and the two yarn ends are arranged in parallel with each other in the splicing chamber, and the untwisting solenoid valve is closed. Then, the solenoid valve is opened, the compressed air enters the splicing chamber, and after a short interruption, the compressed air is injected again. The two airs check the two yarn ends to complete the splicing, the feeding rod and the splicing chamber. The door rotates outward and the splicing yarn is released from the cavity. Small nozzle, to the original position. The yarn clamps and scissors are opened and the drum starts to wind. The yarn hook rotates outward at the same time, the yarn is disengaged, all the mechanisms are returned to the original position. 3 The automatic splicer is debugged. The splicing of the automatic splicer is divided. Debugging and twisting. The two parts first adjust the total intake pressure of the front part. To, the father's maximum no more than 10 fathers 53 total gas pressure is adjusted to 7105 plus total gas to 710 = 3.1 reversal of the commissioning 3.1.1 pressure adjustment according to the specific conditions of the yarn, adjust the retraction pressure, choose According to the production experience, the hemp fiber retreat pressure is adjusted to 2 parent 5! Left and right, the hair of the chemical fiber filaments is adjusted to 3.5 fathers and 104 fathers. At the same time, use a computer to determine the voltage. If the four working voltages are normal, the person points, the potential, the cutoff, the Ding 213 D 4 is successively saturated, and the 8 points are low. Ding 5 cutoff, 16 conduction, relay power. If the yarn detection is not normal, cut off, 8 points output high potential, 15 saturation, 16 cutoff, power loss.

If the voltage of 10 is lost, the ugly base is extremely suspended, the D2 is cut off, the Ding 314 is successively cut off, and the 8-point output is high, and the power is lost. If the 20 voltage is lost. 1 especially work power supply and cut off. D, 14 successive cutoff, 15 points output high potential, power loss. If the 2 team voltage is lost, there is no working power supply and cut off, D 4 is cut off, the output potential is set, D5 is saturated, 16 is cut off, and if 12 voltage is lost, 1 is lost due to no working power. In summary, when the yarn detection is not normal, and 1 202612, the four kinds of working voltages are lost, and the automatic breaking action is caused by the high induced electromotive force during frequent on/off, which easily damages the normally open of the series relays. The contacts automatically shut off the control circuit as soon as the power is lost, thereby stopping the host. When such a host is to be started, it must be energized, its normally open contacts are closed, and the contactor coils can be powered.

4 Conclusion After using the improved circuit, the various conditions of the yarn can be detected online without errors, and the set voltage of each operational amplifier can be flexibly adjusted according to the actual yarn condition. When changing the yarn variety, as long as the work is done before the work, the heavy electricity 1 is matched with the forged pipe to protect the relay.幽18代861 861. And 0. Plus Shanghai textile technology = fabric production is late, retreat 捻 sweat at the beginning of the time, the adjustment is in the cam group 270 positioning, at 3 o'clock, the end of deflation, retreat continued Time can be selected on the panel of the sister 0 system 1310 7 where 1 is equivalent to 2 is quite dry 2, and so on. 0, the action of retreating did not occur.

3.1.2 The change of the tube and the slanting direction is accomplished by the action of the contraction of the air and the holding tube. For different types and different yarns, it is necessary to configure different specifications of 1妁 holding pipe, agriculture, and different debugging methods.

捻 Keep the tube in place. Insert the steering key into the retaining tube, insert the end of the steering key into the recess of the retaining tube, and insert the plastic sleeve into the retaining tube. Under normal circumstances, for the upper holding tube, the steering key should point to 3 o'clock on the key clock, right! For the lower holding tube, the steering key should point to 9 o'clock, and then check the retreat and loosening effect. 1 slightly change the key of the turn key, through a small adjustment to achieve the desired quality of the retreat.

2, the crepe keeps the tube in place. Under normal circumstances, the steering key should be pointed at 9 o'clock in the upper holding tube and 3 o'clock in the lower holding tube. After the adjustment is completed, it is also necessary to check the effect of untwisting and loosening. If necessary, slightly change the position of the turning key for a small amount. Adjustment.

3.1.3 Checking the quality of the yarn back to the yarn and returning the degree of the yarn is 6 appropriate, 圮 to ensure the yarn, the strength of the important prerequisites. Therefore, after the retreat debugging is completed, it is necessary to check whether the quality of the retreat is in compliance with the standard. If the quality of the retort is bad, the original debugging must be re-corrected and the untwisting and loosening of the splicing yarn is confirmed. The diameter of the splicing yarn of the spliced ​​yarn is slightly thicker than the original diameter of the yarn, so that there is enough The strength of the splicing, and no fiber protrudes from the face of the yarn.

The yarn tail is too long. Although the obtained splicing is good, the splicing strength obtained by the longer 3 pool 捻 and the loosening is very strong. The diameter of the splicing is smaller than the diameter of the yarn. 4 is not enough to grab and loosen. Although the connection strength is close to normal, it is slightly insufficient, but the diameter of the joint is much larger than the original diameter of the yarn.

3.2 Twisting of the twisting 3.2.1 The barometric pressure and time parameters are added except for the return. Twisted, between and air pressure. 1 to affect the strength and appearance of the joint, for this necessary debugging must be as fine as possible to adjust the twisting pressure according to the type of fiber, according to the production practice of our factory, the twisting pressure of hemp fiber is adjusted to 758 parent 5 filament The twisting pressure is adjusted to 5056 parent 105, left and right. The twisting pressure of the fiber is adjusted to 31055105, and the basic value in the compressed air twisting pulse system on the computer can be changed according to the type of yarn processed, but the sum of the set values ​​must not exceed 2244, 18. The elbow 1 system panel selects a range of 31 tons 09, the set value 1 corresponds to a time of 2, the set value 2 corresponds to 4, and so on.

The set value and the small twist function do not work. Add the first number to adjust the yarn strength. The bigger the number, the stronger the power. If the ends of the joint are wrinkled, the first number is too large, which will reduce the yarn strength.

The middle number is the pause time, to be smaller, like the 13. The third number is the smoothness of the yarn, the more the number, the brighter the lighter. However, if the number is too large, the joints will have details at both ends. In this case, the third number of digits should be adjusted appropriately. After the adjustment is completed, the edge of the joint should be checked. If the joint is too thick or too thin, the length of the overlap of the yarn ends in the joint groove is changed accordingly, and the worm is rotated to change the flat position of the feed arm and the allowance steel to find the optimum adjustment state.

3.2.2 Debugging of the splicing groove guide plate The positioning of the splicing groove guide plate requires that the outline of the splicing line and the center line of the splicing groove are on the 1 è´ž line, which is subject to the heart line. The error does not exceed 0.1. It should be noted that the guide plate slightly moves outward from the center line of the splicing groove, which will affect the strength and appearance of the splicing yarn. When adjusting, ensure that the two guide plates and the center line of the splicing groove are maintained. The same distance.

3.2.3. Inspection of the knot quality After the splicer has been commissioned, the quality of the splicing must be checked and evaluated. The evaluation of the splicing quality includes the appearance quality and the strength of the splicing.

The crepe must have substantially the same length of the joint; the fibers must be well mixed at the center of the splicing; there is no fiber damage in the splicing area.

The strength is greater than the strength of the original yarn.

There should be no fiber migration and joint sweating at the junction.
