Oil bath wire bundle stretching device

Abstract

The invention relates to the field of polyester spinning stretching, and in particular to an oil bath wire bundle stretching device. The oil bath wire bundle stretching device comprises a front drawing machine roller device, a rear drawing machine roller device and a middle heating device, wherein the middle heating device is arranged between the front drawing machine roller device and the rear drawing machine roller device; the middle heating device is an oil bath tank; soaking rollers are respectively arranged at two ends of the oil bath tank; a guide roller is correspondingly arranged on each soaking roller; the guide rollers are joined with the front drawing machine roller device and the rear drawing machine roller device. By adopting the oil bath wire bundle stretching device, mutual sticking of wire bundles can be avoided, the subsequent wire bundles can be conveniently distributed, stacked and coiled later, the oil bath wire bundle stretching device can be conveniently disassembled and repaired, and the production of waste wires can be also reduced.

Description

technical field [0001] The invention relates to the field of polyester spinning and drawing, in particular to an oil bath filament drawing device. Background technique [0002] In the production of short fibers in chemical fiber companies, PET bottle flakes are generally heated and crystallized first, then melted by a screw, and then drawn into tows through assembly, ring blowing, winding and other processes. After the drawn tows are collected, they are drawn after spinning. Because they cannot be stretched at one time, they need to be drawn in several steps. The drafting process is that the linear speed of the rollers of the drafting machine in the front process is faster than that in the subsequent process. The line speed of the drafting machine roller is slow, and the speed ratio changes with the change of the tow. In the process of drawing the middle tow, the tow needs to be heated, so an oil bath is installed in the middle, because the usual equipment is relatively Old...

Problems solved by technology

After the drawn tows are collected, they are drawn after spinning. Because they cannot be stretched at one time, they need to be drawn in several steps. The drafting process is that the linear speed of the rollers of the drafting machine in the front process is faster than that in the subsequent process. The line speed of the drafting machine roller is slow, and the speed ratio changes with the change of the tow. In the process of drawing the middle tow, the tow needs to be heated, so an oil bath is installed in the middle, because the usual equipment is relatively Old, the oil agent always splashes outside, the oil agent discharge speed is not fast enough when there is entanglement, etc., the tow will always be bonded and twisted in parallel without a separator, two dipping rollers immersed in the oil agent are repaired Inconvenient, there are problems such as the direct impact of the oil in the oil inlet tube on the tow
