Abstract
The utility model discloses a spinning assembly for a polyester fiber. The spinning assembly comprises a distributing plate, an upper filter screen above the distributing plate, and a lower filter screen under the distributing plate. The distributing plate is provided with guide holes penetrating a lower end face. The lower end face of the distributing plate is provided with grooves, and sidewalls of the grooves are provided with diversion trenches penetrating the sidewalls. The upper filter screen is shaped like an umbrella. According to the spinning assembly for the polyester fiber, the structure of the distributing plate is reconstructed, the diversion trenches are additionally arranged, the upper filter screen is transformed into the structure of an umbrella-shaped net, and the melt on the housing wall of the assembly is dredged, and thus blind angles are prevented from generation, yellow slurry is finally reduced, the incidence rate of the yellow slurry in the assembly is dropped to below 2% from 10%, spinning end breaking is reduced, and the quality of filament products is improved.
Description
Technical field
The utility model relates to the polyester filament production technology, relates in particular to a kind of polyster fibre filament spinning component.
Background technology
Filament spinning component is the core that polyester filament is produced, and the formation of assembly has housing, gland, distribution plate, screen pack, sealing ring, spinnerets.The assembly life cycle is 3 months, must decompose by lower machine, and calcining, cleaning, assembling is used again.Assembly belongs to consumable accessory, uses for a long time back casing, distribution plate can damage, be out of shape, and causes melt leakage, produces the dead angle, and the melt degraded forms yellow slurry, finally causes broken end.Common solution is to change housing or distribution plate at present, but expense is higher; Perhaps repair housing, but can not guarantee to recover former state, equally also can cause melt leakage.
Chinese patent 03259726.6 has been introduced a kind of spinning nozzle, makes the cavity of melt process assembly without the dead angle, the shortization discharge time; But filter screen, seal washer, distribution plate are arranged in the cavity, and this invention does not solve distribution plate, enclosure interior increases melt newly by this problem how to solve of dead angle of rear generation after scratching.
Chinese patent 200820155767.1 has been introduced a kind of ring-like spinneret assembly, comprise that the circle scrobicular ring that pressure ring, coagulating bath passage, hollow passageway, pressure ring periphery are provided with is communicated with formation viscose glue passage, top is provided with several spinning head installing holes around through hole, and the bottom is nut structure; In the big nut seat board, be provided with distribution plate, be provided with filter screen at distribution plate, pressure ring is tightly connected with distribution plate and big nut seat board by " O " shape sealing ring simultaneously.This patent is not discussed distribution plate, assembly and is repeatedly used the dead angle of rear damage generation how to solve, and is a kind of invention of novel component.
Chinese patent 200820106779.5 provides a kind of constant temperature, constant voltage composite spinning head apparatus, comprise the parts such as screen pack, distribution plate, sealing gasket, but do not studied this problem how to solve of degraded object that the dead angle produces in spinning head apparatus screen pack, distribution plate, the sealing gasket.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of melt of avoiding to pile up the formation dead angle and produce degradation product at the assembly distribution plate, and reduces broken end, improves the polyster fibre filament spinning component of full-rolling rate and product quality.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of polyster fibre filament spinning component comprises distribution plate, is positioned at the upper filter screen of distribution plate top and is positioned at the lower filter screen of distribution plate top, is provided with the guide hole that runs through upper end and lower surface at distribution plate; The lower surface of described distribution plate is provided with groove, is provided with the guiding gutter that runs through sidewall at the sidewall of groove; Described upper filter screen is umbrella shape.
The design of guiding gutter can keep each local melt to flow, and avoids producing the dead angle; After the damage of inner walls or distribution plate, melt can enter in the groove of distribution plate lower surface by guiding gutter along inwall, and then enters spinnerets through lower filter screen, and melt will form gravity flow, avoids producing the dead angle and forms degradation product.
Because eliminated dead angle in the assembly, after melt was dredged fully, assembly no longer produced degradation product, also can not occur behind the machine on the assembly again, had reduced the spinning broken end, had improved production stability and product quality.
Also be provided with metal washer between distribution plate and lower filter screen, metal washer can be aluminium material, copper material or stainless steel, and the thickness of packing ring can be 2mm or other size; In order to prevent that lower filter screen under high pressure stopping up guide hole or guiding gutter, keep melt unimpeded during the use of metal washer.
The filter mesh layer number of described upper filter screen umbrella shape side portion is higher than the filter screen number of plies at umbrella shape middle part.
Beneficial effect: polyster fibre filament spinning component of the present utility model, by transforming the distribution plate structure, set up guiding gutter, and upper screen pack being transformed into the structure of umbrella shape net, melt to the assembly housing wall is dredged, avoided the generation at dead angle, the final Huang slurry that reduces, slurry incidence in assembly Neihuang County is reduced to below 2% from 10%, has reduced the spinning broken end, has improved the continuous yarn product quality.
