Needle plate girder of high-speed needling machine

Abstract

A needle plate girder of a high-speed needling machine relates to the technical field of non-woven production and comprises a top side plate, a bottom side plate, a left side plate and a right side plate, wherein at least one reinforced rib is arranged between the left side plate and the right side plate, the upper end of each reinforced rib is fixedly connected with the top side plate, and the lower end of each reinforced rib is fixedly connected with the bottom side plate. The at least one reinforced rib is arranged in the middle so that the needle plate girder is improved in strength and is led to be small in volume. Counter-acting forces of felting needles are uniformly distributed on the plurality of reinforced ribs so that bending deformation is small when the contact surface of the needle plate girder and a needle plate works. Each needle is evenly and uniformly stressed so that the needling needle track effect of a whole breadth directional cloth cover is good and high-quality cloth can be produced.

Description

technical field [0001] The invention relates to the technical field of nonwoven production, in particular to a needle board beam of a high-speed needle loom. Background technique [0002] Acupuncture method is the most common and extensive production method in the production process of nonwoven materials. Due to its simple processing technology, short process, flexible and convenient equipment combination, it can adapt to many types of products, wide application fields, low equipment investment, and short construction period. Short and many other advantages, so the acupuncture production method is still the most important non-woven material production process that will develop rapidly and last for a long time now and in the future. The acupuncture process is completed by the acupuncture mechanism, which is the key mechanism of the acupuncture machine. It consists of a main shaft, an eccentric wheel, a needle plate beam, a needle plate, and a needle. At present, the needle p...

Problems solved by technology

The cross-sectional shape of the aluminum alloy needle plate beam is as follows: figure 2 As shown, compared with the steel needle plate beam, it is found that the mass of each piece of the aluminum alloy needle plate beam has not been reduced, and the high frequency and high speed of the acupuncture machine is limited; in addition, the characteristics of the aluminum alloy material make the assembly strength of the needle plate beam It is not as good as steel parts, and some parts assembled on the needle plate beam will reduce the matching accuracy after repeated assembly and disassembly
