Abstract
The invention discloses a gel silk doffing method, which comprises the steps that gel silk enters a speed regulating roller group from a silk guide roller after being discharged from a cooling water bath, and then falls into a barrel after reaching a silk inlet roller and a silk outlet roller; the vertical heights of adjacent speed regulating rollers in the speed regulating roller group have fall, the speed of the speed regulating rollers in the speed regulating roller group is gradually reduced from front to back, the jelly silk enters the silk inlet roller in a loose state after coming out from the silk guide roller, and the jelly silk begins to shrink in the process. The jelly silk enters the silk inlet roller in a loose state after coming out of the silk guide roller, and begins to shrink in the process, the jelly silk can complete 60% of overall shrinkage when moving in the speed regulating roller group, the overall shrinkage amplitude is greatly reduced after falling into the silk containing barrel, the gaps between the periphery of the jelly silk and the four walls of the silk containing barrel are small, and the problems of silk hanging, cracking, toppling and the like are solved.
Description
Technical Field
The invention relates to a gel silk doffing method.
Background
The wet spinning process of ultrahigh molecular weight polyethylene fiber has one step of forming gel filament, and the spinning solution of mixed PE powder and white oil is extruded from spinneret orifice at high temperature and high pressure, cooled in water bath to form gel filament, and the gel filament falls into filament holding barrel for balancing, extraction, drying and hot stretching to form the product. In the silk falling process, the gel silk can continuously seep white oil in the silk when piling up, and the silk becomes thin thereupon, and the volume reduces, and the gel silk can leave flourishing silk bucket four walls all around, along with piling up the height and constantly increasing, produces the string all around easily, and whole cracking, toppling over scheduling problem still can appear when serious, cause the difficulty to follow-up processing.
As shown in fig. 1, in the original production of the gel silk, the silk is ejected from a spinneret plate, stretched by a water tank godet roller V0, cooled in water bath, and then directly falls into a silk containing barrel from a silk inlet roller and a silk outlet roller, wherein the rotating speeds of the silk inlet roller and the silk outlet roller are greater than those of the water tank godet roller V0, the gel silk falls into the silk containing barrel in a tight state, and the gel silk begins to shrink after falling into the silk containing barrel.
Disclosure of Invention
The invention aims to provide a gel silk falling method which greatly reduces the overall shrinkage amplitude after falling into a silk containing barrel and has small gaps between the periphery of the gel silk and the four walls of the silk containing barrel.
The technical solution of the invention is as follows:
a gel silk doffing method is characterized in that: the gel wires are discharged from the cooling water bath, enter the speed regulating roller group from the wire guide roller, then fall into the barrel after reaching the wire inlet roller and the wire outlet roller; the vertical heights of adjacent speed regulating rollers in the speed regulating roller group have fall, the speed of the speed regulating rollers in the speed regulating roller group is gradually reduced from front to back, the jelly silk enters the silk inlet roller in a loose state after coming out from the silk guide roller, and the jelly silk begins to shrink in the process.
The height difference between the upper and lower parts of the adjacent speed regulating rollers in the speed regulating roller group is 1.5-2.5 m.
The jelly silk enters the silk inlet roller in a loose state after coming out of the silk guide roller, and begins to shrink in the process, the jelly silk can complete 60% of overall shrinkage when moving in the speed regulating roller group, the overall shrinkage amplitude is greatly reduced after falling into the silk containing barrel, the gaps between the periphery of the jelly silk and the four walls of the silk containing barrel are small, and the problems of silk hanging, cracking, toppling and the like are solved.
Drawings
The invention is further illustrated by the following figures and examples.
Fig. 1 is a schematic view of a conventional jelly yarn dropping device.
Fig. 2 is a schematic diagram of a gel silk dropping device adopted by the invention.
Detailed Description
A method for falling gel silk comprises the steps that gel silk 1 is discharged from a cooling water bath 2, enters a speed regulating roller group 4 (10 speed regulating rollers are adopted in the embodiment) from a godet roller 3, then falls into a barrel 7 after going to a silk inlet roller 5 and a silk outlet roller 6; the vertical heights of adjacent speed regulating rollers in the speed regulating roller group have fall, the speed (V1-V10) of the speed regulating rollers in the speed regulating roller group from front to back is gradually reduced, the gel silk enters the silk inlet roller in a loose state after coming out of the silk guide roller, and the gel silk begins to shrink in the process. The height difference between the upper and lower parts of the adjacent speed regulating rollers in the speed regulating roller group is 1.5-2.5 m.
Claims (2)
1. A gel silk doffing method is characterized in that: the gel wires are discharged from the cooling water bath, enter the speed regulating roller group from the wire guide roller, then fall into the barrel after reaching the wire inlet roller and the wire outlet roller; the vertical heights of adjacent speed regulating rollers in the speed regulating roller group have fall, the speed of the speed regulating rollers in the speed regulating roller group is gradually reduced from front to back, the jelly silk enters the silk inlet roller in a loose state after coming out from the silk guide roller, and the jelly silk begins to shrink in the process.
2. The jelly-silk doffing method according to claim 1, characterized in that: the height difference between the upper and lower parts of the adjacent speed regulating rollers in the speed regulating roller group is 1.5-2.5 m.
