1.Horizontal correction Move the machine to an appropri […]
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, and measure with a spirit level to make the machine level. After the determination, tighten the fixing screws. Prevent displacement.
Measure at the power inlet, measure whether the voltage of the three-phase power supply is correct and meet the specified power requirements of the machine. After it is determined, fix it line by line, and make sure that it is correct before turning on the power.
3. Dry run
Enter the basic parameters on the machine's computer to perform shaker correction, auxiliary roller correction, encoder correction, needle selection time correction, and head origin correction. After the above is done, perform dry operation. During dry operation, adjust the left and right of the head ( The dry running program is 6 + 6 fine-grained yarn-free weaving). Test the yarn feeders 1-8 and test for no less than 48 hours. The purpose is to allow every part of the new machine to run in. The oiling time of the needle plate and guide rail is 24 hours / time.
4.Adjustment 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 head of the switcher eats the yarn feeder symmetrically, adjust the position of the brush, and the standard of the front and back of the brush is parallel to the needle. Stick it on the needle, and the height of the brush is the height of the lifting eye (ie, the ring). Cover all the antennas and side antennas, keep the sand mouth tight and properly, and adjust the pulling force of the cloth wheel holder and the main roller.
5, get up with empty line
First check the use of yarn feeder (height, front, back, up and down clearance); check the width (status of open stitches); degree; speed; rollers; pull and opening and closing of the secondary roller; parking point of the yarn feeder; check the speed of execution, Its base head 20, secondary roller opening and closing 20, side roller pulling force 77, speed 100/40% (full speed is 100, now speed is 40).
6, 6 + 6 detailed weaving
Objective To integrate the needle path with the needle plate knitting, make the knitting needles flexible in the needle groove, and insist on the selection of the needles-whether there is a random flower phenomenon.
7. Measuring head (coil size)
When the degree value is 50, 30cm yarn weaves 9cm fabric, so that the degree measured by each system of the front and back beds is the same, and the values of different models with different needle numbers are different.
8.Flip needle test
Use the needle turning program to knit the needle turning test to see if there is a time difference between the front bed and the back bed and each mouth. You can move the machine head up and down to adjust the time difference between the needle turning.
After observing the above actions, take a second measurement. Because the needle is turned to adjust the up and down of the moving head, the degree is changed. Therefore, repeat step 7 to measure the degree.
10.Total needle correction
Weaving test with Siping mesh (full stitch rib knitting) program, see how fast the machine feeds the yarn, compare it from the woven cloth, adjust the method, loosen the arch screw on the machine head, move the machine head box left and right to make the yarn evenly fed, Make Siping eyes flat (that is, see if they are large or small).
11.Double color general needle
Use two systems with two different colors of yarn to simultaneously weave four flat meshes. The purpose is to observe whether the two systems have large and small meshes. Repeat step 8 if there are large and small meshes.
12, starting single yarn
The two systems use woven weft flat tissues to see if there is a single thread in the eye, and the purpose is to observe that there is a single thread when the needle is too much, and repeat 9 if there is one.
13, 6 + 6 two-color jacquard weave
Due to the turn-up test, the machine head is adjusted up and down, and the total needle test is adjusted to the left and right of the machine head, which results in a change in the needle selection time. To change the needle selection time (the specific adjustment is described in the paper), this test starts from the bottom speed and slowly accelerates to the maximum speed of 120cm / s. If there are no random flowers, the adjustment is completed.
14.Flip stitch knitting
Test to see if a single line appears when flipping the pins, and sometimes repeat steps 6-11. Test whether there are random flowers in the hanging eyes and yarn ejection in the eyes. Adjust the computer parameters of the machine to solve the yarn ejection problems.
