Aramid tow drafting and stretch breaking spreader

Abstract

The invention discloses an aramid tow drafting and stretch breaking spreader which comprises an extending unit, a drafting unit, a primary pulling and cutting unit, a secondary pulling and cutting unit, a drafting even and orderly unit, a rear re-cutting unit, a front re-cutting unit, an electrostatic eliminator, a driving mechanism, a conveying mechanism, a spreading mechanism, a rack and a pull-down type pressurizing mechanism. According to the aramid tow drafting and stretch breaking spreader, an upper-eight and lower-sixteen combined type roller structure is utilized to carry out seven-area drafting and stretch breaking composed of omega type and concave circular arc type different holding manners on aramid tows, so that reliable working performance of the complete machine is ensured,the quality of the spun product made by the aramid tow drafting and stretch breaking spreader is improved, and the production efficiency and the working efficiency of the complete machine are improved.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to an aramid tow breaking machine. Background technique [0002] In recent years, with the continuous diversification of fiber application fields, the market demand has continued to increase. Due to the unreasonable structure and drafting layout of the tow breaking machines currently used in the market, there have been many defects in use: one is because in The static electricity generated by the fibers in the production process makes the fibers easily entangled with the rollers, so the output speed of the machine can only be reduced to ensure the normal operation of the machine, which seriously restricts the output of the machine. , leading to more ultra-long fibers, which affects the production of the subsequent process and the quality of the finished product, and restricts the market share of the product; the third is that the drafting transmission of the whole machine ...

[0002] In recent years, with the continuous diversification of fiber application fields, the market demand has continued to increase. Due to the unreasonable structure and drafting layout of the tow breaking machines currently used in the market, there have been many defects in use: one is because in The static electricity generated by the fibers in the production process makes the fibers easily entangled with the rollers, so the output speed of the machine can only be reduced to ensure the normal operation of the machine, which seriously restricts the output of the machine. , leading to more ultra-long fibers, which affects the production of the subsequent process and the quality of the finished product, and restricts the market share of the product; the third is that the drafting transmission of the whole machine is all mechanical drafting, that is, gear transmission, and different feeding Quantification needs to adopt different drafting ratios, so it is necessary to manually replace different transmission gears, which is time-consuming and labor-intensive and extremely inconvenient; Fourth, due to the use of traditional upward pressure cylinder pressurization, the height of the equipment is too high for the operator to handle It is a physical test when the machine breaks down
