Description
Technical field
The present invention relates to the special pipe abrasion-proof mechanism that a kind of ring throstle is used for the 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, increased the pneumatic apparatus for collecting of negative pressure of a fiber strip polymerization in the dominant draft downstream, pneumatic apparatus for collecting is mainly by special pipe, gather grid ring, gather the formations such as roller and grid ring tension bracket supporting mechanism, have a plurality of air-flow guide grooves on the tube wall of the centralizing pipe working face of special pipe, gather the densely covered pore of grid ring upper surface, a plurality ofly gather respectively corresponding being sleeved on each air-flow guide groove of centralizing pipe of grid ring, make the corresponding one fiber strand of each air-flow gathering sill, in centralizing pipe under the negative-pressure air-flow effect, the fiber strip filoplume is gathered at the air-flow guide groove when gathering the grid ring rotational conveyance, and effectively reduce spinning triangular zone, reach the requirement that reduces Yarn filoplume and increase the brute force of yarn.
Present special pipe great majority adopt aluminium section bar, process through hardening oxidation on the surface, so special pipe case hardness after treatment is between HV400-HV460, and this hardening oxidation layer thickness is thin, generally between 0.04-0.08mm, because the surface treatment cost is higher, so that the cost of manufacture of special pipe is high, the service life of special pipe after treatment is usually about 1-3.When normal spinning, gather in the grid ring rotation process and can form local friction in the edges and corners of special pipe small curvature radius, therefore hickie appears in this part hardening oxidation layer Fast Wearing of special pipe after the friction, thereby whole special pipe is scrapped because of this place's Fast Wearing, moreover owing to the hardening oxidation layer friction of gathering grid ring and aluminium section bar can produce static, be disadvantageous to the spinning data of spinning the chemical fibre class.
For this reason, long for improving special pipe ABRASION RESISTANCE and life-span, reduce cost, flow-guiding mouth on the working surface of special pipe is coated with suspended hood, and suspended hood is fixed on the aspiration channel, and suspended hood is provided with and gathers groove, but because induced draft cover is provided with and gathers groove, 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
Purpose of the present invention provides a kind of ABRASION RESISTANCE and the life-span that can improve special pipe, and can not cause the ring throstle of energy windage loss for the special pipe abrasion-proof mechanism of negative pressure collecting spinning apparatus.
For the technical scheme that achieves 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 more than one groove and at least one suction hole of gathering that communicates with negative pressure cavity along the tube wall that gathers working face, and 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 the contacted arc wearing plate of grid ring 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 gather grid ring directly with the cambered surface wearing plate or/and wear-resisting bar contact, because it is thick many that the Thickness Ratio hardening oxidation layer thickness of the thickness of cambered surface wearing plate and wear-resisting bar is wanted, can greatly improve the ABRASION RESISTANCE of negative pressure collecting pipe, improve again its long service life, reduce production costs.The cambered surface wearing plate that the present invention only is connected with at small curve cambered surface place at the negative pressure collecting tube wall is or/and wear-resisting bar, because of wearing plate or/and wear-resisting bar do not communicate with the cavity that negative-pressure air-flow is arranged, there is not negative-pressure air-flow to pass through any one side of this wearing plate or wear-resisting bar, thereby avoided the leakage of negative-pressure air-flow, energy savings.
