Seven-roller drawing machine for simultaneously processing 32 bundles of aramid fibers

Abstract

The invention discloses a seven-roller drawing machine for simultaneously processing 32 bundles of aramid fibers. The drawing machine comprises a yarn guide mechanism and a winding reel, a machine base is arranged at the bottom of the yarn guide mechanism, a plurality of supporting seats are arranged at the bottom end of the side wall of the machine base, grooves are formed in the bottoms of the supporting seats, a plurality of springs are arranged in the grooves at equal intervals, supporting blocks are arranged at the bottoms of the springs, a plurality of upper-row drafting rollers and a plurality of lower-row drafting rollers are arranged in the yarn guiding mechanism and are arranged in a staggered mode, turbines and transmission shafts are arranged between the upper-row drafting rollers and the lower-row drafting rollers, the winding cylinder is connected with the top of the yarn guiding mechanism through a connecting cylinder, and a controller is arranged in the right side of the yarn guiding mechanism. The supporting seats are arranged at the bottom of the machine base, the springs are arranged at the bottom of the supporting seats, compared with a transmission supporting seat, the device is more stable, and a base is effectively prevented from toppling or being damaged.

Description

technical field [0001] The invention relates to a seven-roll drafting machine for simultaneous processing of 32 bundles of aramid fibers. Background technique [0002] The full name of aramid fiber is "aromatic polyamide fiber", which is Aramid fiber in English (DuPont's trade name is Kevlar, which is a kind of aramid fiber, that is, para-aramid fiber), which is a new type of high-tech synthetic fiber. It has excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. Its strength is 5 to 6 times that of steel wire, its modulus is 2 to 3 times that of steel wire or glass fiber, and its toughness is 2 times that of steel wire. times, and the weight is only about 1 / 5 of the steel wire, at a temperature of 560 degrees, it will not decompose or melt. It has good insulation and anti-aging performance, and has a long life cycle. The discovery of aramid fiber is considered to be a very important histor...

Problems solved by technology

[0003] The seven-roll drafting machine that needs to be used in aramid fiber processing, the current guide wire machine structure is relatively complex, the operation is difficult, and it is inconvenient to maintain when a fault occurs. Secondly, the noise generated by the entire machine during operation is relatively high. Large, it will cause great harm to the human body, and it can no longer meet the requirements of modern production, especially the multi-channel drafting and multi-surface drafting cannot be achieved, and it is difficult to achieve a good drafting effect
