Abstract
The utility model discloses a paper tube used in polyester synthetic fiber production. The paper tube comprises a paper tube body, wherein a protruded band is arranged at each of the two ends of the paper tube body; the protruded bands are provided with fillets and are formed by adhering glass paper. By adopting the paper tube, the protruded bands replace an unwinding disk, so that the production cost is reduced, and the labor intensity of workers is reduced; furthermore, when a fiber barrel is unwound until the diameter is 5 to 15 mm, the breakage rate is reduced, and polyester pre-oriented yarns (POY) are completely unwound; the flexibility of the paper tube is improved, and the recycling utilization rate is increased; moreover, the phenomenon of scattering caused by damage to yarn strips because of friction between the yarn strips and a pressing disk during start winding can be avoided; the utilization rate of subsequently produced and processed tail fibers is increased; and the waste is reduced.
Description
Technical field
The utility model relates to polyethylene terephthalate (terylene) production field, particularly a kind of paper tube that in polyethylene terephthalate is produced, uses.
Background technology
Along with the quick raising of China's polyester filament output, the paper tube use amount of the strand that in the production of polyethylene terephthalate, is used for reeling is very huge, for practicing thrift cost, avoiding waste, need carry out recycling to paper tube.
Often break end when the unwinding of POY (high speed spinning) silk tube is to 5-15mm in DTY (low elastic polyester filament) course of processing, just bottom rouleau silk end breakage rate is very high, and major cause is that POY paper tube end face burr is hung up precursor.Like Fig. 1, shown in 2, because the DTY process velocity is higher, when the POY tow is unwound to bottom, the shake aggravation that the unwinding of tow forms, tow is easy to contact the paper tube end face, and the burr friction with the paper tube end face causes broken end.Particularly use the POY paper tube that reclaims, the broken end phenomenon is more outstanding, and the disposable use of paper tube; Can cause great waste and cost to increase again; And the recycling paper tube is the developing direction of conservation-minded society, under the prerequisite of recycling paper tube, how to reduce the end breakage rate in the unwinding process; Increasing the clean rate of moving back of POY precursor, is the problem that the spinning industry presses for solution.
At present, way is to add a cover an auxiliary take-off device-unwinding dish in POY paper tube termination usually, and ganoid unwinding dish has been isolated tow and in the unwinding process, contacted with the paper tube end face; Guaranteed that the unwinding of POY silk is clean; Yet, can solve the problem that tow is hung up by the paper tube end face though install auxiliary take-off device additional, can cause productive costs to increase; Workman's work capacity increases, and work efficiency descends.
The utility model content
To the problems referred to above, the purpose of the utility model provides a kind of little to productive costs influence, can alleviate working strength of workers, and end breakage rate reduces when making the unwinding of silk tube to 5-15mm, and the unwinding of POY silk is clean, and can realize repeating nonexpondable paper tube.
For achieving the above object, the utility model adopts following technical scheme:
A kind of paper tube that in polyethylene terephthalate is produced, uses comprises the paper tube body, and respectively there is a protruding band at said paper tube body two ends, and said protruding band is set to fillet.
Further, said protruding band is pasted for glass paper and is formed.
Further, said paper tube body internal diameter is 112mm, and external diameter is 126mm, and long is 150mm.
Further, the surface of said paper tube body is a craft paper.
Further, said protruding bandwidth is 2-20mm, and height is 0.1-1mm, and outside fillet is R=1.0-1.5mm, and inboard fillet is R=0.2-0.5mm.
Further, said protruding bandwidth is 8mm, and height is 0.2mm, and outside fillet is R=1.0-1.5mm, and inboard fillet is R=0.1mm.
Further, also comprise seal wire groove and/or tail fibre groove, said tail fibre groove is 7-8.5mm apart from the end.
Further, said tail fibre groove apart from the end 8mm.
Further, a kind of manufacturing approach of the paper tube that in polyethylene terephthalate is produced, uses: at first process the paper tube body, then paper tube body middle part is suppressed, make paper tube body two ends form protruding band.
The utility model is owing to adopt above technical scheme, and it has the following advantages:
1. protruding band is set at the paper tube two ends; And protruding band is set to fillet, and in the time of can effectively preventing the unwinding of silk tube to 5-15mm, two ends of precursor and paper tube body contact; Avoid the burr at paper tube body two ends to hang up precursor; And the fillet setting also is difficult for hanging up precursor, reduces end breakage rate, guarantees that the unwinding of POY precursor is clean.
2. protruding band adopts glass paper to paste and forms, have certain height, can play the effect of unwinding dish; Improve and be unwound into power; Compare with increasing auxiliary take-off device, cost increases minimum, and glass paper is pasted the protruding belt surface slyness that is produced; Thoroughly isolated paper tube body burrs at two ends avoids hanging up precursor.
3. adopt glass paper to paste the convexity band that forms, can well protection sheet tube body end, make the end of paper tube body burr can not occur, increased the toughness of paper tube, be that the recovery Occupation coefficient of paper tube improves greatly, practice thrift cost.
4. the convexity band that is provided with can also avoid strand in initial winding process, to cause the strand damage to produce the tail phenomenon of loosing with the platen friction, has improved the tailfiber degree of utilization of subsequent production processing, cuts the waste.
