Description
Technical field
The utility model relates to the anti-wear mechanism of special pipe that a kind of ring throstle is used for negative pressure integrated composite spinning device, belongs 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 formations such as roller and grid ring tension bracket supporting mechanism, gathering of special pipe has a plurality of air-flow guide grooves on the tube wall of managing working face, gather the densely covered pore of grid ring upper surface, a plurality ofly gather that grid ring is corresponding respectively to be sleeved on each the air-flow guide groove that gathers pipe, make the corresponding one fiber strand of each air-flow gathering sill, in gathering pipe under the negative-pressure air-flow effect, the fiber strip filoplume is gathered on 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, handle through hardening oxidation on the surface, therefore 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, make the cost of manufacture height of special pipe, 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 this part hardening oxidation layer of friction back special pipe weares and teares fast and hickie occurs, thereby whole special pipe is worn and torn fast because of this place to be scrapped, moreover, be disadvantageous to the spinning data of spinning the chemical fibre class owing to the hardening oxidation layer friction of gathering grid ring and aluminium section bar can produce static.
For this reason, long for improving special pipe ABRASION RESISTANCE and life-span, reduce cost, be coated with suspended hood on the flow-guiding mouth on the working surface of special pipe, suspended hood is fixed on the aspiration channel, and suspended hood is provided with and gathers groove, but because air draught covers to be provided with and gathers groove, therefore pass through at negative-pressure air-flow, be easy to reveal negative-pressure air-flow, cause energy loss from the both sides of suspended hood.
Summary of the invention
The purpose of this utility model provides a kind of ABRASION RESISTANCE and the life-span that can improve special pipe, and can not cause can windage loss ring throstle be used for the anti-wear mechanism of special pipe of negative pressure integrated composite spinning device.
For the technical scheme that achieves the above object is: a kind of ring throstle is used for the anti-wear mechanism of special pipe of negative pressure integrated composite spinning device, comprise that the negative pressure with negative pressure cavity gathers pipe, negative pressure is gathered pipe and 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, it is characterized in that: the tube wall that described negative pressure is gathered 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.
The utility model negative pressure is gathered tube wall and 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 the thickness of the thickness of cambered surface wearing plate and wear-resisting bar is than thick many of hardening oxidation layer thickness, can improve the ABRASION RESISTANCE that negative pressure is gathered pipe greatly, improve its long service life again, reduce production costs.The utility model only gathers cambered surface wearing plate that tube wall is connected with at small curve cambered surface place or/and wear-resisting bar in negative pressure, 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.
