Important maintenance items for computer pattern machine, computer pattern maintenance and needle selection
From the simplest place, see if the small gripper is too stressed. The small gripper controls the length of the thread. If the pressure is too large, the thread is too short. When sewing for the second time, the thread will be taken out of the pinhole. The computer fancy machine is important for maintenance, computer pattern maintenance and needle selection.
GF Series Rebar Stirrup Bending Machine include GF20 and GF20 CNC, which can apply 3phase motor and single phase motor to supply power.
3phase 380V /220V/440V 50/60Hz is the popular motor in construction site.
GF 20 automatic Rebar Stirrup Bending Machine can bend round steel bar with diameter Φ4-Φ20mm to various geometrics shape as required by construction.
1.Standard angle, fast speed, angle variation freely. Convenient of angle adjustment, just need to shift induced magnet.
2.Convenient use, light and handy.
Computer pattern machine important maintenance matters
First, how to solve the short pinhole of the thread after the computer car is cut
1. From the simplest place, see if the small tensioner is too stressed. The small gripper controls the length of the thread. If the pressure is too high, the thread is too short. When sewing for the second time, the thread will come out of the pinhole.
2. When working with the tangent electromagnet, pay attention to see if the large gripper pops open. If it doesn't bounce, push the big gripper a little inward.
3. Pay attention to see if the position of the tangent cam is correct. There is a high possibility of this problem.
4. Check if the handwheel is installed correctly and the sensor at the handwheel is installed correctly.
5. If it is a brother's computer needle car, or a brother-like computer flat car, pay attention to see if the moving knife installation position is too front end, that is, the tangent is too early.
6. If it is a heavy machine or a heavy machine, pay attention to whether the fixed position of the fixed knife is on the left.
7. Note if the retainer is too stressed.
Second, several faults caused by the loss of the friction plate in the servo motor
1. The power supply (refers to the computer box) is automatically cut off, but the power indicator on the head of the computer sewing machine is still on, and the hand can not be placed on the motor by touching the motor. This is too much loss of the outer friction plate (the friction plate has inside and outside Two) should be replaced. Sometimes the power indicator on the head of the sewing machine is turned off. The same is true. This refers to the sudden power cut during the sewing operation. The inside and outside of the friction plate are separated by the front section of the motor. The first thing you see is the outside, and the one you see later is the inside.
After the sewing of the computer car is finished, the tangential line is cut, and the tangential action is slow. Sometimes, when the thread is cut, the computer box automatically cuts off the power supply. This is caused by the excessive loss of the friction lining inside, and should also be replaced; or the oil on the friction lining inside is caused by oil stains. Should be cleared. Clearing method: sandpaper can be gently sanded on the cork, then wipe with a cloth.
1. In the sewing process, the needle stop position is wrong (refers to the position of the induction coil and the line is in good condition, the heavy machine company has positioned the needle in the sewing machine to stop the needle when the sewing machine leaves the factory, that is, the needle is below After the sewing is finished, the needle is stopped, that is, the needle is on the top) or the needle is not positioned correctly after the thread is cut. This is caused by dust or oil on the surface of the friction sheet inside, as long as the surface is removed. If necessary, the adhesive produced by the heavy machine company can be rubbed slightly on the surface of the cork, but it should be noted: Do not use a lot of additives, otherwise it will be counterproductive and bring some trouble.
2. After the induction coil is damaged, after the motor is started, the sewing machine foot enters the high-speed sewing state as soon as it is stepped on, and cannot stop. In another case, the magnet in the induction coil on the pulley is taken off or the coil is taken off, which is also the case. .
3. Regarding the alignment of the tangential time in the tangential mechanism, any three automatic sewing machine has a standard time of tangential cutting. The standard of this machine of the heavy machine company is that when the hook tip hooks the upper thread when the needle is lifted up, when the bottom thread is pressed by the hand, the roller is embedded in the cam as a standard state, and at the same time, it is cut off. The length of the thread is adjusted to adjust.
