Description
Technical field
The present invention relates to the special pipe abrasion-proof mechanism of a kind of ring throstle for negative pressure collecting spinning apparatus, belong to the pneumatic apparatus for collecting technical field of compact spinning machine.
Background technology
Compact spinning machine is for eliminating spinning triangular zone, the Pneumatic negative-pressure apparatus for collecting of a fiber strip polymerization is added in dominant draft downstream, pneumatic apparatus for collecting is primarily of special pipe, gather grid ring, gather the formation such as roller and grid ring tension bracket supporting mechanism, the tube wall of the centralizing pipe working face of special pipe has multiple air-flow guide groove, gather grid ring upper surface to gather pore, multiplely gather that grid ring is corresponding to be respectively sleeved on each air-flow guide groove of centralizing pipe, make the corresponding one fiber strand of each air-flow gathering sill, in centralizing pipe under negative-pressure air-flow effect, fiber strip filoplume is gathered while gathering grid ring rotational conveyance on air-flow guide groove, and effectively reduce spinning triangular zone, reach the requirement of the brute force reducing Yarn filoplume and increase yarn.
Current special pipe great majority adopt aluminium section bar, surface is through hardening oxidation process, therefore special pipe case hardness is after treatment between HV400-HV460, and this hardening oxidation layer thickness is thin, general between 0.04-0.08mm, because surface treatment cost is higher, make the cost of manufacture of special pipe high, the service life of special pipe is after treatment usually at about 1-3.When normally spinning, gather in grid ring rotation process and can form local friction in the edges and corners of special pipe small curvature radius, therefore after friction there is hickie in this local hardening oxidation layer Fast Wearing of special pipe, thus whole special pipe is scrapped because of this place's Fast Wearing, moreover can electrostatic be produced due to the hardening oxidation layer friction gathering grid ring and aluminium section bar, be disadvantageous to the spinning data spinning chemical fibre class.
For this reason, for improve special pipe ABRASION RESISTANCE and the life-span long, reduce costs, flow-guiding mouth on the working surface of special pipe is coated with suspended hood, and suspended hood is fixed on aspiration channel, and suspended hood is provided with and gathers groove, but gather groove because induced draft cover is provided with, therefore pass through at negative-pressure air-flow, be easy to reveal negative-pressure air-flow from the both sides of suspended hood, cause energy loss.
Summary of the invention
Object of the present invention provides a kind of ABRASION RESISTANCE and the life-span that can improve special pipe, and can not cause the special pipe abrasion-proof mechanism of ring throstle for negative pressure collecting spinning apparatus of energy windage loss.
For the technical scheme achieved the above object is: a kind of ring throstle is used for the special pipe abrasion-proof mechanism of negative pressure collecting spinning apparatus, comprise the negative pressure collecting pipe with negative pressure cavity, negative pressure collecting pipe is provided with along the tube wall gathering working face communicate with negative pressure cavity more than one and gathers groove and at least one suction hole, it is characterized in that: the tube wall of described negative pressure collecting pipe is connected with at the small curve cambered surface place of radius of curvature≤8mm and gathers arc wearing plate that grid ring contacts or/and wear-resisting bar.
Negative pressure collecting tube wall of the present invention is connected with at small curve cambered surface place and gathers cambered surface wearing plate that grid ring contacts or/and wear-resisting bar, make to gather grid ring directly with cambered surface wearing plate or/and wear-resisting bar contacts, because the thickness of cambered surface wearing plate and the Thickness Ratio hardening oxidation layer thickness of wear-resisting bar want thick many, greatly can improve the ABRASION RESISTANCE of negative pressure collecting pipe, improve again its long service life, reduce production cost.The cambered surface wearing plate that the present invention is only connected with at small curve cambered surface place at negative pressure collecting tube wall is or/and wear-resisting bar, because of wearing plate or/and wear-resisting bar does not communicate with there being the cavity of negative-pressure air-flow, there is no negative-pressure air-flow by any one side of this wearing plate or wear-resisting bar, thus avoid the leakage of negative-pressure air-flow, economize energy.
