    How to scientifically debug three needle five line flat seaming machine 超级管理员View Times:12 2015-07-15
    In the commissioning of three needles and five lines of seaming machine before, first of all, we should confirm the accuracy of the machine meets the requirements. For equipment with the gap of the gap to the factory, to change the original part of the original factory, so that the machine precision is close to the condition of the factory. And then, according to the requirements of the use of the manual to check the location of the size and the timing of each other.
    Below, the author according to personal experience, the use of the manual adjustment of the requirements of the focus of finishing and replenishment (some of the wording may be different from the description of the instructions).
    Adjustment of timing of machine needle and bending needle
    Machine needle with curved needle with timing adjustment, the most important and most easily overlooked is that the needle dropped to the lowest point in the curved needle must move right to the farthest limit position, the same crash needle rose to the highest point bending the needle must move to the left to the farthest limit position, it should be repeated observations confirm.
    In addition to the action of the left and right, the action of the curved needle and the former (far from the operator) to the operator. At this time we have to pay attention to make the most quick time to move around the curved needle to move around the limit position, to make the movement of the curved needle before and after the move to the left to reach the position of the needle to reach a minimum.
    At this point, we have to pay attention to both the right and the left and right position, both to prevent the bending of the needle to move to the left when the needle, but also to prevent the curved needle to move to the right when the needle. Of course, we can also adjust the size of the needle bar and a small clockwise rotation angle to achieve the best results. Some machines can adjust the range of movement before and after bending.
    The needle drops to the lowest position, bending machine needle tip distance right 3mm-4mm. The needle rises, curved needle move to the left, to the right center of the needle tip bending when bending tip is positioned below the needle needle above 2.5mm. At this moment, the gap between the curved needle and the needle is 0~0.05mm.
    The needle drop to bend the needle back, left needle curved needle head needle and thread hole meet. At this point, allowing the back of the bending needle slightly contact with the needle, but it is best not to scratch, or the smaller the better.
    Adjustment of front and rear guard
    Before and after the adjustment of needle guard needs to follow the principle is: before and after the retaining pin from the direction of the operator watch contour should be with the machine needle in the needle tip line, in order to prevent the machine needle jitter bundle in protecting the needle, the needle guard near the machine needle side should be properly chamfered. Front (close to a human operator) needle guard to protecting needle also blocking the sewing thread loops are formed in the eye of a needle of a machine in front (close to a human operator), so that the machine needle needle behind the line smooth ring formation. After the needle is not only to play the role of the needle can not stop the smooth formation of the ring.
    Because of the difference in the production enterprise and the machine model, the shape of the front and rear guard, can allow the adjustment range of the different and ideal condition there is a certain gap, the maintenance personnel in the specific circumstances to the principle of the need to follow the rules.
    The needle moves down, before and after the needle guard toward and away from the machine needle direction; the needle from the lowest position rises, before and after the retaining needle to close to the machine needle direction.
    The needle down to the needle guard position, needle guard should hide boot needle and needle, avoid scratch.
    In addition, when the bending tip to the left to move to the right position, the front and rear retaining needle, the gap between the front (close to the operator side) of the needle and the machine needle is 0.1mm-0.3mm, the gap between the needle and the needle is 0~0.1mm.
    Looper thread take-up cam adjustment
    Looper thread pick cam line because of the different plant design, some with the actual needs of the size and shape may some of the gap, the gap is too large to cause jumpers and increase the difficulty of maintenance.
    Looper thread pick cam is: when bending the needle moves to the left in a timely manner to bend the needle which provides mobile and knitting stitch sewing line line, when bending the needle moves to the right to timely recover excess sewing thread.
    The need to pay particular attention to is: in order to facilitate machine needle to bend the needle back of the triangular line loop, with the help of looper thread take-up cam in the machine needle to enter the triangular line loop, the looper thread is in a state of tension. But excessive tension will cause the looper thread disconnection and sewn back is in tight looper thread.
    Looper thread pick cam adjustment standard is: the needle down, left machine needle tip reach bending under the needle along is exactly and steadily into the cam ring, the curved needle pick cam curved sewing in pick the highest point of the cam profile.
    Looper thread pick cam speed to make minor adjustments on the basis of the standard, according to their direction of rotation adjustment fast joint material on the back of the stitch is looper thread tension is relatively loose, on the contrary, it is the looper thread tension is tight.
    Stretch needle and needle tension adjustment board
    Some brands of machines, timing and seaming needle machine needle can be adjusted. Such as Tongyu F007 three needle five lines stretch sewing machine can by adjusting the tension and the needle cam (f00710004) relative to the angle of shaft of section (f00708001) to adjust the tension and the machine needle and needle with timing. With the best time is, after the needle drops, the right needle into tight ring sewing needles began to move to the right guy.
    Seaming needle swing amplitude must ensure that when seaming needle swing to the right limit position of left back when can hook to stretch the needle, when seaming needle swing to the left when the tension and the tip to the left needle distance is 4.5mm-5.5mm.
    Stretch needle mounting height should be by as much as possible, but the tension and the needle above and seaming needle over the gap between the pallet below should be able to so that the tension and the needle through smoothly.
