Leakage plate of 7.5 micrometer electronic yarn drawing equipment

Abstract

The invention discloses leakage plate of 7.5 micrometer electronic yarn drawing equipment, which comprises a plug, a bottom plate, an electrode, a leakage nozzle and a side wall, wherein a liquid flowing groove is formed between the side wall and the bottom plate; a plurality of reinforcing ribs are connected on the bottom plate; a flanging is welded on the top of the side wall; an electric heating couple is arranged on the side wall; and the electric heating couple is positioned at the outer side of the liquid flowing groove; the electrode is positioned on the plug; a plurality of leakage nozzles are distributed on the bottom plate; two rows of leakage nozzles are arranged in parallel in a staggered manner; and a guide plate is arranged above the bottom plate. According to the invention,compared with the existing six-division pull E225-1200H leakage plate, the leakage plate of the 7.5 micrometer electronic yarn drawing equipment, has the improved eight-division pull E225-1600H leakage plate, so that the glass liquid flow rate is improved, and the production efficiency is improved; the adjustment of the thickness of the electrode improves the temperature of the settable leakage plate; the aperture of the leakage plate increases by 0.1mm compared with that of the six-division pull E225 leakage plate, and the flow rate of the glass liquid increases at the same temperature of theleakage plate, so that the aim of improving the wire drawing rotating speed is achieved; and the distribution of the peripheral leakage nozzles is optimized, and the quality abnormality such as fly filament, hairiness and the like easily caused by larger tension compared with other areas is reduced.

Description

technical field [0001] The invention relates to the field of glass fiber primary twisted yarn, in particular to a bushing plate of a 7.5um electronic yarn drawing equipment. Background technique [0002] The existing E225 drain plate is mainly 1200H, that is, six partitions, and there are fewer partitions, resulting in low glass liquid flow per unit time and low efficiency. The thickness of the six-point drawing electrode and the aperture of the leak nozzle should not be set at a high temperature, which cannot meet the requirements of the high-speed wire drawing process. During the use of the six-point leaking plate, the temperature of the leak nozzle in the periphery of the single zone is lower than that of other zones, and the tension is too high compared with other zones, which may cause abnormal quality such as flying silk and hairiness. [0003] Main problems and disadvantages: [0004] 1. Liufenla E225-1200H has fewer partitions, low production efficiency, high unit ...
