Analysis of the broken latch needle problem of the flowering machine!

The use of the knitting machine should be an effective way to achieve recycling and environmental protection, and we should enhance our understanding of it. Do you know? On a high-speed knitting machine, the phenomenon of latch needle breakage directly affects the weaving quality of the fabric. When knitting, the reason for the latch needle breakage is due to the continuous collision between the latch needle and the valve of the triangle, and between the needle latch and the needle bar. The main cause of the collision is: when the latch needle contacts the curved triangle, the curved triangle will have an impact on the latch needle; when the latch needle contacts the needle guard triangle, the needle guard triangle will also have an impact on the latch needle. The impact force of the curved triangle on the knitting needle is about 250 microseconds, so the impact force of the curved triangle changes relatively little. Because the ratio of the shock wave time of the curved triangle to the natural frequency of the latch needle is large, no longitudinal degree will be formed on the latch needle. However, the impact force of the needle guard triangle will reach a peak at about 5 to 10 microseconds. Therefore, under the impact of the needle guard triangle, the stress wave will quickly transmit the entire latch needle back. At this moment, the speed of the latch needle slows down rapidly, which will cause the needle hook to produce bending vibration. At the same time, the impact force of the needle tongue will also intensify the bending and wrenching of the needle hook due to the wave action. The above is all the content we brought about the flower machine. If you want to know more, please follow us! I still remind everyone that the recycling of resources will become more and more important in the future! .
