Improved M type draw texturing machine and hanging type bearing structure thereof

Abstract

The invention discloses an improved M type draw texturing machine which comprises an upper hot box, a lower hot box and a coiling apparatus. The upper hot box and the lower hot box are arranged oppositely, a first godet wheel and a second godet wheel are arranged at the discharging ends of the upper hot box and the lower hot box respectively, and a third godet wheel is arranged between the second godet wheel and the coiling apparatus. The invention also discloses a hanging type bearing structure provided with a bearing seat and a bearing, and the first godet wheel, the second godet wheel and the third godet wheel are arranged on the inner ring of the bearing through a wheel spindle. According to the improved M type draw texturing machine and the hanging type bearing structure thereof, the first godet wheel, the second godet wheel and the third godet wheel are improved from a fixed wheel type to a driven rotating wheel type assembling structure through the hanging type bearing structure, friction coefficient can be greatly reduced and tow tension can be stabilized, broken filament and ossified filament are not easy to generated, nexus and shrinkage can be more even, netting wires are reduced, physical index of coefficient of variation (CV) value of tows is lower and more stable, and can be reduced by 1%, and full-package rate can be improved by 20%.

Description

technical field [0001] The invention relates to a textile equipment, in particular to an M-type texturing machine and its bearing structure for installing a godet wheel. Background technique [0002] The texturing machine is mainly used to process untwisted yarns such as polyester (POY) and polypropylene fibers into elastic yarns with high impact and low elastic performance through twisting and deformation. Reloading machine". [0003] Texturing machines can be divided into Y-type texturing machines and M-type texturing machines. In the existing Y-type texturing machine, in order to avoid the tension fluctuation from the first roller to the second roller to cause excessive wrap angle and friction, the upper heating box is arranged vertically. Since the upper and lower operating positions are far apart, it is difficult to Multiple operators are required. Compared with the Y-type texturing machine, the M-type texturing machine has the advantages of compact structure, small ...

Problems solved by technology

[0009] However, since the first godet wheel 4', the second godet wheel 9' and the third godet wheel 13' respectively adopt a fixed wheel mounting structure, they cannot rotate around their axes, resulting in the first godet wheel 4', The wrap angle of the second godet 9' and the third godet 13' is relatively large, which increases the relationship between the tow 1a and the first godet 4', the second godet 9' and the third godet accordingly. The friction coefficient of the wheel 13', especially the wrap angle of the first godet wheel 4' is too large, and the greater the tension is, the greater the friction coefficient will be. The tension of this part 150D is generally 43-48g

In this way, it is very easy to generate static electricity and fuzz, especially when the POY raw material has uneven oiling, fuzz and stigma, when the tow 1a passes through the first godet wheel 4' and the second godet wheel 9' and the third godet 13', it will cause the coefficient of friction to change, resulting in tension fluctuations or fuzz

When tension fluctuations or fuzz are formed, the angle of the tow 1a in the twister 5' will change, resulting in broken ends, tow jumping, uneven untwisting, and formation of border silk and other undesirable phenomena

[0010] Because the wrap angles of the first wire guide wheel 4', the second wire guide wheel 9' and the third wire guide wheel 13' in the M-type texturing machine are too large, resulting in a large friction coefficient, it is easy to produce wool , and when the raw material is poor, it is easy to multiply the bad raw material phenomenon, and its full volume rate is usually low, generally below 60%.
