Computerized flat knitting machine brush and needle problem


When the computerized flat knitting machine is in use, there will be problems with the brush and needle lock. For these two faults, let's look at the specific solutions:

Computer flat knitting machine-needle lock

Computerized flat knitting machines select needles through pins. The alignment of the pins is very important, which directly affects the operation of the machine. If the pins are not aligned, it will cause needle leakage. Generally, high-pin needles do not need to be raised. Needle must be raised for low stitches. For example, when weaving one plus one sesame puller collar, the needle is selected through the high and low stitches. If the stitches are not aligned, there will be missing stitches, so pay attention to the arrangement of the stitches .

The brush problem is also very important in the leakage of the needle. The brush problem is mainly caused by the following aspects: the brush device is bad, the front and back are not correct, the brush is installed and the needle does not close the angle, the device is too high to resist the rebound of the needle tongue The brush does not open the tongue, it takes too long, and the hair is seriously shed or bitten, and the quality of the brush is a problem. Computerized knitting machine manufacturers supply quality brush every knitting machine.

(1) Defective brush device. The front and back are not correct, and the brush must be aligned before and after, because when the head pulls the triangle movement back and forth, the knitting needle also moves, and the needles on both sides are carried out at the same time. The brush has a downward pressing tongue to make It can smoothly remove the ferrule, so there can be no front and back irregularities. If it is not correct, some needle tongues will not be pressed down to form a missed needle. To solve this problem, you should adjust the brush.

(2) The brush is installed reversely and does not close the angle with the needle. For this problem, it is the same as mentioned above, so the brush should be adjusted.


Explanation of computer flat knitting rings


Computerized flat knitting machine is a kind of double needle plate tongue weft weaving loom. Its triangle installation is like a set of flat cams. The needles of the knitting needles can enter the grooves of the cams, and the triangles are moved to force the knitting needles to perform regular lifting activities in the needle grooves of the needle board, and then move through the hook and the tongue , You can knit the yarn into a knitted fabric. During the ascent of the knitting needle, the coil gradually withdraws from the hook, open the needle, and withdraw the needle from hanging on the needle bar; during the descending of the needle, the hook hooks the newly placed yarn and pulls it. Pull and bend to form a loop, and the restored loop will come out of the needle hook. The new loop will pass through the old loop and be connected in series with the old loop. Many knitted loops will form a knitted fabric.

Looping process: The process of knitting the yarn into fabric by the knitting needles of the flat knitting machine is called the looping process.The looping process can be divided into withdrawal, underlaying, banding, silence, looping, knockout, looping, and pulling. Wait 8 segments

Rewinding is to move the old coil in the needle hook to the needle bar to prepare for the laying of new yarn. In the process of withdrawing, the knitting needle rises from a lower point to a higher point, and the needle is in the withdrawing phase. After the withdrawing, the needle tongue is scraped by the loop.

Yarn insertion is to place the yarn on the needle tongue.After the unwinding is completed, the beginning of the knitting needle drops.Because of the common action of the yarn feeding mechanism, the yarn is placed on the needle hook through the yarn feeder under the guidance of the yarn guide. Underneath, above the tongue, so that when the knitting needle continues to drop, the hook can firmly hold the yarn.

Banding yarn is the process of introducing the yarn under the hook into the hook. This process is accomplished by relying on fabric descent.

Silence is to block the needle mouth so that the old loop of yarn placed on the new pad is separated by the needle tongue. After the process without yarn is completed, the yarn is accurately caught by the needle hook, and the knitting needle continues to drop.The old coil that fell on the needle bar slides along the needle bar toward the needle and moves to the lower part of the needle tongue. Effect, twist at the beginning about the axis of the needle tongue, when the needle is lowered again, the needle twists to cover the needle hook to block the needle mouth, the needle is lowered along the triangular task surface, and the newly placed yarn passes through the old loop, and The old coil also came out of the needle due to the effect of the pulling force.

The task of the looping stage is that after the old stitch comes out of the needle, the needle hook takes the newly placed yarn through the old stitch, and the knitting needle descends to pull the yarn into a new stitch.

Pulling is to make the new loop after the loop is tensioned, and the needle hook must not be taken off for the next loop weaving task. Pulling is to use the pulling mechanism to pull the old coil toward the back of the needle to reach the serious goal, and also pull the formed fabric out of the loop area.

Gathering process Gathering is one of the basic loop structures of knitted fabrics. It is a kind of organization that keeps the old loops without looping back or unlooping, and the knitting needles continue to loop, and the new and old loops are assembled together. On the flat knitting machine, two methods are used to make the trapping organization, one is the method without looping, and the other is the method without retracting.

The no-hoop method is to push one of the flat knitting machines or the two pressure needles of the front and back diagonally to a certain height. When the head is required to drive the triangle, the knitting needle rises to a higher point, and then descends to the silent stage, which is no longer lowered. The loop closes the tongue and hangs on the needle bar. At this time, the needle hook catches the newly placed yarn. When the machine head runs in the reverse direction to knit the next row of fabric, the knitting needle can rise to the extreme point or lower to the lowest point under the effect of the triangle. The new yarn constitutes the old loop hanging on the needle bar after the cantilever is withdrawn. Mergers form a trap after they are taken together.

The no-return method is also called fat flower tissue, which can only be woven on the fat knitting machine. The two-level fat knitting machine constitutes a parallel cluster, and the three-level fat knitting machine can constitute an interwoven cluster.
