How To Debug The Computerized Flat Knitting Process

How to debug the computerized flat knitting process

1. Level correction

Move the machine to an appropriate position, insert the tellurium pads, adjust the height of the four corners, adjust the height adjustment screws on the tellurium pads, measure with a level to make the machine in a level state, after confirming, tighten the fixing screws, Prevent displacement.

2. Power measurement

Measure at the power entrance to measure whether the voltage of the three-phase power supply is correct and meet the specified power requirements of the machine. After confirming, fix it line by line, and then energize after confirming that it is correct.

3. Dry operation

Enter the basic parameters on the computer of the machine, perform shaker calibration, auxiliary roller calibration, encoder calibration, needle selection time calibration, and head origin calibration. After the above is done, perform dry operation. During dry operation, adjust the left and right sides of the head ( The dry running program is 6+6 fine mesh no yarn knitting), test the yarn feeder 1-8, the test is not less than 48 hours, the purpose is to make every part of the new machine run-in, the needle plate and guide rail oil time is 24 hours/time.

4. Adjust before weaving

Open the head cover, the program is the total number of stitches, adjust the height of the switcher (0.5-0.3MM), the switcher's switch head symmetrically eats the yarn feeder, adjust the position of the brush, the front and back standard of the brush is parallel to the needle Stick it on the needle, the height of the brush is the height of the tuck (i.e. tuck) and cover the needle. Adjust all the antennas and side antennas, keep the sand nozzle tight, and adjust the cloth wheel support and main roller tension properly.

5. Get up on empty line

First check the yarn feeder usage status (height, front and back, upper and lower gap); check the knitting width (the number of open stitches); degree; speed; roller; sub-roller tension and opening and closing; yarn feeder parking point; check the execution speed, Its bottom degree is 20, the secondary roller opens and closes 20, the side roller pulls 77, and the speed is 100/40% (full speed is 100, and the current speed is 40).

6, 6+6 detailed weaving

The purpose is to integrate the needle path and needle board knitting, make the knitting needles flexible in the needle groove, and insist on the needle selection-whether there is squandering phenomenon.

7. Measuring mesh (coil size)

When the mesh value is 50, 30cm yarn is knitted into 9cm fabric, so that the measurement mesh of each system of the front and rear beds is the same, and the value of the model with different needle sizes is different.

8. Needle transfer test

Use the needle transfer program to knit the needle transfer test to see if there is a time difference between the front bed and the back bed and each port. You can move the machine head up and down to adjust the time difference of needle transfer.

9. Measuring mesh

After observing that the above-mentioned actions are correct, perform the second measurement, because the up and down of the moving handpiece is adjusted by turning the needle, which causes the change of the measurement, so repeat step 7 to measure the measurement.

10. Total needle correction

Use the Sipingme (full needle rib knitting) program to knit and test, see how fast the machine feeds the yarn, compare the weaving pieces, adjust the method, loosen the dome screw on the head, move the head box left and right to make the yarn feed evenly, Make Sipingme flat (that is, see if it is large or small).

11. Two-color total needle

Simultaneous knitting of Siping meshes with two different colors of yarns with dual systems. The purpose is to observe whether there are large or small loops in the two systems. Repeat step 8 when there are large or small loops.

12. Starting single yarn

The two systems use knitting weft and flat weave respectively to see if there is a single thread at the end of the eye. The purpose is to observe that there is a single thread when the needle is eaten too much, and repeat 9.

13, 6+6 two-color jacquard weaving

Because the needle transfer test adjusts the machine head up and down, the total needle test adjusts the left and right of the machine head, resulting in a change in the needle selection time, so do 6+6 double-color jacquard knitting to observe whether the needle selection time is correct, and use the computer's parameter correction To change the needle selection time (the specific adjustment is introduced in the paper), this test starts from the bottom speed and slowly accelerates to the maximum speed of 120cm/s. If there is no stray flower, the adjustment is completed.

14. Knitting tuck

Test whether there is a single thread when flipping the needle, sometimes repeat steps 6-11. Test whether the tuck has squandering and whether the tuck position has spitting. If squandering, adjust the machine computer parameters to solve the spitting.
