Abstract
The utility model relates to a hollow air draft roller, which is applicable to a compact spinning machine and belongs to the field of a textile machinery fitting. The compact spinning hollow air draft roller comprises a core rod (1) and a hollow air draft roller sleeve (2). The core rod is characterized in that the effective length part is a through long cylinder; a connector and a connection hole are respectively additionally arranged at a shaft neck and a shaft end; the hollow air draft roller sleeve is characterized in that through holes are uniformly distributed in the outer surface; the through holes are in a shape of a combination of a round shape and a kidney shape; a certain included angle is formed by the projection of the through holes and the axial line of the cylinder. According to the hollow air draft roller provided by the utility model, the intensity of the connected roller can be improved and the curvature can be reduced due to the core rod (1), so that the quality of yarns can be improved; the machining efficiency can be improved through the shape of the through holes of the hollow air draft roller sleeve (2), so that the yarn hairiness is reduced, the quality of the yarns can be improved and the waste of the enterprise labor and the raw materials can be reduced; the machining difficulty can be greatly reduced due to the selected material of the hollow air draft roller sleeve (2), so that the cost is reduced and the benefits can be improved.
Description
Technical field
This is suitable for the novel roller that a kind of compact spinning uses that relates to, and belongs to textile machinery accessories field;
Background technology
Before this is suitable for novel making, the hollow roller mandrel that compact spinning uses is all by guide pillar (1-1), external screw thread (1-2), total length diameter effective length part (1-4), endoporus (1-5) and internal thread (1-6) part formation not etc., because internal thread diameter is larger, cause roller wall thickness thinner, easily produce distortion, and, roller only has a guide pillar to support while connection, easily produce compared with macrobending, also easily make after machine operation, to produce flexural deformation on roller, thereby affect yarn qualities simultaneously; Before this is suitable for novel making, the hollow roller that compact spinning uses overlaps wind inlet or is thousands of single circular holes, working (machining) efficiency and low, with high costs; Be single rectangular through-hole, although processing is easier, the effect that reduces Yarn filoplume is not good enough, affect yarn qualities, and easily stops up inner air draught part, the unstable and textile enterprise that causes yarn qualities manually with raw-material a large amount of wastes.
Summary of the invention
This is suitable for novel object and is to overcome above-mentioned deficiency, provide a kind of processing easy, with low cost, not yielding, reduce that Yarn filoplume is effective, yarn qualities stable, saving textile enterprise artificial and raw-material compact spinning air draught hollow roller.
This is suitable for novel object and is achieved in that a kind of compact spinning hollow air draught roller, comprise plug (1) and hollow air draught roller cover (2), plug (1) is characterised in that: the effective length part (1-4) of plug (1) is for there being the elongated cylinder of same diameter of certain tolerance, be convenient to the assembling of hollow air draught roller cover, also be convenient to processing, meanwhile, be also convenient to the unification of inner air draught part reference for installation; Increase connector (1-3) and connecting hole (1-7) part, thereby strengthen the intensity after roller connects and reduce flexibility, improve yarn qualities; Hollow air draught roller cover (2), is characterized in that: cylinder length (L) is 30～50mm, and external diameter (D) is 45～70mm; On outer surface, uniform through hole (2-1) is shaped as the combination of circular and kidney-shaped; Through hole (2-1) projection and cylinder axial line have certain angle (a).
Material selection aluminium alloy or the copper alloy of described hollow air draught roller cover (2).
Compared with prior art, this is suitable for novel beneficial effect and is: process easy, with low cost, not yielding, reduce Yarn filoplume effective, improve and stable yarn line mass, save textile enterprise manually and raw material, reduce production costs, increase economic efficiency.

Fig. 1 is this structural representation that is suitable for Novel hollow air draught roller.
Fig. 2 is plug (1) schematic diagram.
Fig. 3 is the front elevation of hollow air draught roller cover (2).
Fig. 4 is the operation principle schematic diagram of hollow air draught roller cover (2).
Fig. 5 is the wherein a kind of of shape of through holes.
Wherein: plug 1, hollow air draught roller cover 2, air draught through hole 2-1, without boundling yarn 3, yarn 4 after boundling, negative-pressure air-flow flows to 5.
The specific embodiment
Referring to Fig. 1, this is suitable for the novel a kind of compact spinning hollow air draught roller relating to, and comprises plug (1) and hollow air draught roller cover (2).
Referring to Fig. 2, this effective length part (1-4) that is suitable for the novel plug relating to (1) is for there being the elongated cylinder of same diameter of certain tolerance, necked part is made up of guide pillar (1-1), external screw thread (1-2), connector (1-3), and axial end portion is made up of guide hole (1-5), internal thread (1-6) and connecting hole (1-7).
Referring to Fig. 3, this is suitable for novel hollow air draught roller cover (2) length (L) relating to is 30～50mm, and external diameter (D) is 45～70mm; The combination through hole (2-1) of uniform circle and kidney-shaped on outer surface, circular port diameter (e) is 0.3～2.5mm, and the length (f) of mounting hole is 0.8～30mm, and mounting hole width equals circular port diameter; Through hole (2-1) projection and cylinder axial line have certain angle (a), and a is+10 °～-10 °.
Referring to Fig. 4, this total length j that is suitable for novel upper every the through hole of hollow air draught roller cover (2) relating to is 4～35mm.
Referring to Fig. 5, under the effect of negative-pressure air-flow, gather fast contraction without the yarn yarn of boundling, reach minimizing filoplume, increase the effect of single thread force.The uniform air draught through hole of hollow air draught roller cover (2) outer surface, because mounting hole is than larger with the circular hole area of diameter, thereby reduce the distance between wind inlet, reduce the amplitude of negative pressure fluctuation, also increased the frequency of negative pressure work, make fiber can be subject to better negative pressure control, effectively reduce Yarn filoplume, guarantee the stable of yarn qualities; Simultaneously, the shape of through hole and structure distribution can effectively guarantee again the equilibrium of negative pressure, reduce because mass efficient fiber is with the negative pressure waste causing of running off, also reduced the probability of stopping up through hole and inner air draught element due to a large amount of effective fibers that run off, further guarantee the stability of yarn qualities, reduce the artificial and raw-material waste of textile enterprise, reduced production costs, increased economic efficiency.
Hollow air draught roller cover (2) adopts aluminium alloy or copper alloy material, can significantly reduce difficulty of processing, directly reduces production costs.
