Commissioning of computerized flat knitting machines

1. Level correction: move the machine to an appropriate position, insert the foot tellurium pad, adjust the height of the four corners, adjust the height adjustment screws on the foot tellurium pad, measure with a level meter, make the machine in a horizontal state, to be determined , Tighten the fixing screws to prevent displacement.

2. Power supply measurement: measure at the power supply inlet to measure whether the voltage of the three-phase power supply is correct and meets the power requirements of the machine. After the determination, fix it line by line, and make sure that it is correct before it can be powered on.

3. Dry run: Input the basic parameters on the computer of the machine to perform shaker calibration, auxiliary roller calibration, encoder calibration, needle selection time calibration and machine head origin calibration. , Adjust the left and right of the machine head (the dry running procedure is 6 + 6 fine yarn-free knitting), test the yarn feeders 1-8, the test is not less than 48 hours, the purpose is to make every part of the new machine run-in, needle plate The oiling time of the guide rail is 24 hours / time.

4. Adjustment before weaving: open the machine head cover, the program is the total number of needles, adjust the height of the switch (0.5 ~ 0.3MM), the switch head of the switch is symmetrical about the yarn feeder, adjust the position of the brush, the standard of the front and back of the brush It is attached to the needle in order to be parallel to the outgoing needle. The height of the brush is the height of the hanging eye (that is, the tuck). Appropriate (by experience).

5. Get up with empty thread: first check the yarn feeder usage status (height, front, back, up and down clearance); check the knitting width (the condition of the number of stitches opened); gauge; speed; roller; secondary roller pulling force and opening and closing; yarn feeder parking point ; Check the execution of the written speed, its base level is 20, the opening and closing of the secondary roller is 20, the pulling force of the side roller is 77, and the speed is 100/40% (full speed is 100, now the speed is 40).

6, 6 + 6 fine knitting: The purpose is to fuse the needle path and the needle board knitting, make the knitting needle flexible in the needle groove, and insist on the needle selection situation-whether there is a mess of flowers.

7. Measuring head (coil size): When the measuring head value is 50, 30cm yarn is woven into 9cm fabric, so that the measuring head of each system of the front and rear beds is the same, and the values ​​of the models with different needle numbers are different.

8. Needle-turning test: Use the needle-turning procedure to knit the needle-turning test to see if there is a time difference between the front bed and the back bed and the openings. Move the machine head up and down to adjust the time difference of the needle turn.

9. Measuring head: After observing the above actions are correct, measure the head again, because the needle up and down adjusts the movement of the machine head up and down, causing the change of the measuring head, so repeat step 7 to measure the measuring head.

10. Correction of total needle: weave test with four flat-mesh (full needle rib knitting) program, see the machine's yarn feeding speed, compare from the woven fabric piece, adjust the method, loosen the arch screw on the machine head, move the machine head left and right The box equalizes the yarn feeding and makes the Siping mesh smooth. 

11. Two-color main needle: Use two different colors of yarn to weave four flat meshes at the same time with the double system. The purpose is to observe whether the two systems form loops with large and small meshes. Repeat step 8 when there are large and small meshes.

12. Single yarn from the bottom: the two systems use woven weft to see if there is a single thread. The purpose is to observe if there is a single thread when the needle is eating too much, and if there is, repeat it 9.

13. 6 + 6 two-color jacquard knitting: Because the needle turning test adjusts the head up and down, the total needle test adjusts the left and right of the machine head, resulting in changes in the needle selection time, so do 6 + 6 two-color jacquard knitting to observe the needle selection Whether the time is correct, use the computer's parameter correction to change the needle selection time. This test starts from the bottom speed and slowly accelerates to the maximum speed of 120cm / s. If there are no messes, the adjustment is completed.

14. Turning knitting eyelet: test if there is a single thread when turning the needle, and sometimes repeat the steps to check if there is any mess in the city eyelet and whether there is yarn spit at the eyelet position. The messy flower adjusts the machine computer parameters and solves the problem of spinning.
