After a certain number of years of use of the water jet loom, some of the loom weaving shafts will produce abnormal shaking during the operation, and the domestic weaving machine is more serious, which will cause the warp to fluff and break, and the silk surface appears no. The regular crossbar is the file, which leads to a decline in production efficiency and a decline in product quality.
According to the observation of the production situation, the main reasons for the abnormal vibration of the weaving machine shaft are:
1. The tension on the warp is not determined properly.
In particular, if the tension of the upper machine is too large, it is easy to cause abnormal shaking of the weaving shaft. Therefore, before production, according to the type of warp, the total number of warp threads and the thickness of the thread, the required total warp tension is correctly calculated to determine the weight of the weight, and at the same time adjust the tension of the continuously variable transmission tension rod and the relaxation spring. The weight arm is level.
2, the warp belt tension is improper.
The position of the V-belt should be adjusted to meet the theoretical requirements when the tension gauge measures the V-belt tension.
3. The wear of the large shaft bearing of the weaving shaft causes the abnormal vibration of the weaving shaft due to improper force.
The large-shaft bearing should be inspected carefully to see if it is worn, and the bearing sleeve is inspected for wear. If there is wear, it should be replaced in time, and the lubricant should be added when changing.
4. The warp beam bracket and the warp beam cover are worn.
If it can be repaired, it can still be used. If it can be repaired, if it can't be repaired, it should be replaced in time and adjusted to meet the installation requirements.
5. Improper combination of delivery and gear.
Because of its misalignment, the transmission is not smooth, and the jitter occurs; the appropriate number of gear teeth should be calculated according to the weft density of the fabric, and the correct modulus fit should be selected.
6. The gearbox is short of oil, damage, rust, and the drive is not correct and produces jitter. It should be corrected in time to ensure that there is no shortage of oil, no damage, no rust.
7. The shaft of the weaving shaft is loose and the outer head is loose.
If it can be repaired in time, it should be repaired immediately. If it cannot be repaired in time, it should be repaired in time.
8. The weaving shaft bracket cover pin bolt is not fully tightened and should be tightened in time.
The reason for the above-mentioned abnormal vibration of the weaving shaft may be one, or two or three. The maintenance worker must carefully observe and carefully analyze the repair, and promptly and carefully repair it when the cause is correctly determined.
