In view of the chaotic quality of threading machines in the market at present, our company has developed a new threading machine.
At present, the main disadvantage of threading machine is that it can't thread and the tension is small. Actually, it is impossible to thread, which is caused by the unreasonable design of the threading machine itself. Experienced users know that it will be OK as soon as they buy it back, and the threading distance will be short in a few days, which is caused by the unsynchronized wire feeding mechanism and winding mechanism. (The early structure was responsible for winding and sending the thread, so it won't be sewn here.
As long as we discuss thread delivery first,
Can the machine reach the working time of wire feeder?
At this time, the take-up mechanism is relatively reversed, whether it is in an empty and relatively static state, and whether the thread feeding mechanism can be pulled by the thread threader. If it can't idle, it still runs at its own speed.
1, if it is lower than the wire feeding speed of the wire feeding mechanism, the wire feeding wheel will strain the threader and consume the energy of the motor because of the fast wire feeding speed and insufficient length.
2. If the speed of the take-up mechanism and the wire feeding mechanism is faster than that of the wire feeding mechanism at this time, the wire feeding mechanism will not be able to send the wire out in time, which will cause the threader to loosen and get entangled in the machine.
Secondly, when picking thread, the thread feeding mechanism cooperates with the thread picking mechanism to pick thread reversely. If it is faster than the thread take-up mechanism, it will not pull the thread into the machine because of the load at this time as above. Because the take-up wheel does not take up the thread early, it will also have severe friction with the take-up wheel, which will damage the take-up device and the take-up wheel and even lose energy. It won't be slower than the take-up reel, because designers all know to make the take-up reel messy in the machine.
If there is a design, when the thread is fed, the idle resistance of the thread take-up wheel is static, and the thread take-up wheel will pull it through the winder. When winding, the take-up wheel will idle, and the take-up wheel will pull the take-up wheel through the winder. This is the best design, which is easier said than done. Later, it was designed to use electromagnetic clutch to solve the problem. Some people have electromagnetic clutches, which only solve half the problem. However, it is logical to use two to solve the problem. Generally, it can be used at the primary end of power, with high speed and low friction, because the high-speed end saves labor. Just like we repair many machines, we can pull the V-belt of the motor by hand, but we can't push the working side of the machine to rotate, so the electromagnetic clutch can't leave when winding. Because of the heavy load, some people say it can be used at the primary end. Sorry, if it is used in the primary end, it needs two independent deceleration mechanisms, which are for the threading machine. Then there is no design after the motor slows down, which can be like the head brake on the circuit brake. Power is equivalent to power supply. When the head brake is pushed to the left, the left circuit is connected, the wire feeder works, the head brake is opened and pushed to the right, the right circuit is connected, and the take-up mechanism works. At this time, the left side is dead and the wire feeding is idling. Attention, everyone, this is an example of the transmission structure of the threading machine after deceleration. This kind of fall braking control circuit can't be used to solve practical problems, because if you use two motors, there is this kind of fall braking. On the one hand, the motor slows down to the working part, and even if there is no electricity, the other one pulls him, which is very heavy (you know, if you integrate a motor reducer, it is very laborious for you to rotate that output shaft), so it is to design the roll braking and roll driving on the mechanical transmission. Through practice, in view of the practical problems of the threading machine, Senchao Machinery has designed a turnover drive, which solves the problem that when the wire feeding and winding work independently, the other one is in a static state without resistance and any other working parts are pulled by the threading machine.
