How does the machine in the textile mill automatically wiring

The automatic wiring is completed by the splicer of the automatic winder, and there are air twisting and water twisting.

Take the air splicer as an example, and the splicing technology uses an air splicer instead of a knotter, creating conditions for the production of knotless yarns.

Before the automatic winder splinters, if the electronic yarn clearer detects that the yarn unwinding from the package has yarn defects, the upper yarn catcher will continue to lead the yarn until it is rejected and then spliced, and the lower yarn catcher can control the length of the yarn through the sensor, that is, the yarn of the upper yarn catcher is not finished, and the lower yarn catcher will not continue to lead the yarn when the yarn reaches the required length and is in a waiting state. At the same time, because the upper and lower yarn traps and splicers are driven by stepper motors separately, they are independently controlled; If one of the two yarn catchers does not catch the yarn head, it continues to find the head, while the other is in the waiting splice state after the other has finished capturing the yarn head, and the knotter waits until both yarn catchers have reached the correct position before starting the knot. This reduces compressed air consumption and filament return, noise and component wear.

I really haven't seen a loom with automatic wiring, the thread can't be broken all the time, and if it keeps breaking, it's a yarn problem. The weaving will be processed before the weaving is carried onto the machine. The location of the broken wire is different, and if you study it slowly, maybe there will be hope, haha.

I haven't seen the automatic wiring, and most of them are manually connected.

The left thumb is sandwiched in the middle of the x, the black line goes around the thumb, around the "green" line, on the red line, the red line goes around the black line, the left thumb holds, and then the black line is pulled successfully. (For your observation, the green line is actually black).

Pinch the thumb of the left hand in the middle of the x, the black line bypasses the thumb, bypasses the "green" line, puts it on the red line, the red line goes up and bypasses the black line, the left thumb holds, and then pulls the black line, success. (For your observation, the green color on the end of the thread is actually black).

If you are a spinning stopper, you should use a bag joint, and if you are a weaver, you should use a single-turn joint.

In fact, the joints are very simple, I also learned for a few days, that is, two, three will not wear, others can be.

I'm a spinning yarn stopper, what do you want this for?

Joint requirements: Adopt the "flat joint" method. The joints should be done: one good, two light, three accurate, four short, five combined, and six fast.

One good: joint***;

2. Light: the joint action is light (heavy action is easy to produce white spots);

Three quasi: the length of the chuck head is accurate (16mm-22mm), and the joint position is accurate (the right side of the middle and upper part of the roller);

Four short: short yarn introduction (five spindles, four spindle spacing), short yarn lifting (no more than the velvet roller) five combinations: intubation, yarn guide hook, chuck cross combination.

Six fast: extubation, head finding, hanging wire loop, air ring ring, intubation, and fast winding of the yarn guide hook.

Spun joint method:

1. Before 92 years, the flat joint light picking method was adopted, when the joint, the head was directly picked close to the whiskers, and when the hand was operated, there was no focus point, which was easy to produce a large impact on the joint;

2. In 92, the method of resisting the pipe joint began to be implemented, and the middle finger against the pipe joint and the thumb and index finger clamp head were fed into the whisker method, which was fast and the joint was small.

3. The method of tight spinning joints is currently relatively chaotic, there is no unified regulation, and there are many methods used, such as the head method, the pipe method, the rubber roller method, and the hanging head method; At present, the most commonly used is the rubber winding roller method, regardless of the quality of the joint, through the electric clearance check. From the perspective of the traditional fine sand joint operation, the method of throwing in from the leather roller is undoubtedly contrary to the operation specification, but considering that "it can be removed on the electric cleaning to ensure the quality of the cloth surface", it is a special solution for special varieties.

No matter what you do, you must pay attention to safety, especially the car stopper, and the fine sand is better.

Cotton thread to avoid ash can not be solved as soon as possible!

When I feel the thread sucking down, it starts to push into the skin.

Depending on what model, the old-fashioned 601 is to rely on the feel, the left hand to the bottom of the barrel frame, and the right hand to introduce the yarn head in time. One car, one connection. Titan ET320 is different. Mainly by feel.

I just went in to learn the question, I understand what you said, but I just can't answer it, you can talk to your colleagues who work with you, they will understand these questions after a long time.

Question: Aren't you professional?

Answer the pre-twisting and post-twisting decapitation. The main reason for the breakage before twisting is that when the fiber is conveyed to the agglomeration tank, the fiber arrangement is destroyed by different forces in the process of cohesion and merging, and there is a leading or lagging movement, focusing on the impurities, fine dust, dead cotton bundle and the instability of operation and negative pressure in the sliver. The broken end after twisting is mainly caused by the large loss of twist and the change of the volume and twist of the yarn in the process of twist transfer.

I'm not asking how to judge, I'm asking how to answer skills?

In which factory, I'm also a car stopper.
