Description
Technical field
The utility model relates to a kind of ring ingot negative pressure type compact spinning fine spining machine air box, belongs to the compact spinning machine technical field.
Background technology
Ring ingot negative pressure type compact spinning fine spining machine is for reducing spinning triangular zone, increased the negative-pressure air-flow apparatus for collecting of fibre strand integrated composite in the dominant draft downstream, under the suction function in shape tube, fiber strip is along with the grid ring rotational conveyance time, the place is gathered at the shape tube guide groove, or rotate with air draught paddy roller and to be gathered in its surface, thereby effectively reduce spinning triangular zone, reach the purpose that reduces Yarn filoplume and increase yarn strength.Therefore when encircling the spinning of ingot negative pressure type compact spinning fine spining machine, must provide a negative pressure of gathering usefulness, and this negative pressure value sets by spinning different yarn counts and kind, when spinning, also require this negative pressure value constant.
Because ring ingot negative pressure type compact spinning fine spining machine need break end at the former ring throstle of reservation and inhale outside the cotton negative pressure, increased the negative pressure of a fiber aggregate, and these two negative pressure value size requirements are different, poor approximately 2-3.5 doubly, simultaneously do not have redundant space because the reasons in structure of fine spining machine is inhaled cotton negative pressure air channel, tube connector, cotton suction duct place at former broken end, thus great majority design at present cotton sucking blower with gather the blower fan branch and be arranged.The following three kinds of structures of main at present employing, first structure is to be arranged near the fine spining machine creel top gathering the air channel, gather blower fan and be arranged on former cotton sucking blower top, cause the air box height to become very high like this, the used in addition power of fan that gathers is more usually at 10-15KW, when therefore two blower fans were worked simultaneously, the vibration of air box was big.Second kind of structure is that a plurality of blower fans that gather for a short time are arranged near the fine spining machine main shaft top on the deadlight, one group of little blower fan with gather for a short time the air channel communicate and provide the 36-48 ingot required gather negative pressure.Its weak point is that to gather blower fan more, needs more than 20 to gather blower fans for 1008 ingot cars, and a plurality of to gather the air channel not only misaligned, it is big to take up an area of the space, and noise is big, especially a plurality ofly gathers the direct air draft of blower fan in the workshop, also environment is caused certain dirty beam.At present compact structure is respectively to put a negative pressure wind cabinet at headstock, tailstock place, inhales cotton air channel still to be arranged in the middle of the former ring throstle deadlight top, and the cotton sucking blower case is arranged on above the geared head; Gathering the air channel is arranged near the creel top or creel bottom reel cage pole axle top, be arranged on the former tailstock and inhale cotton bellows place and gather air box, not enough place is that air box is placed on above the geared head, the geared head height also becomes higher on the one hand, and have the big problem of vibration too, and its vibration counter extensioin drive disk assembly is also unfavorable.
And adopt a typhoon machine for the card air box structure of spinning of rubbing, provide simultaneously by a thick high large pipeline and inhale cotton air channel and gather the required negative pressure in air channel.Not enough place can only be used to the rub ring ingot negative pressure type compact spinning fine spining machine of the formula of spinning of card, because of it gathers required negative pressure is to inhale about 2 times of cotton negative pressure, and the required negative pressure of gathering of other ring ingot negative pressure type compact spinning fine spining machine is to inhale about 3.5 times of cotton negative pressure, and air box when work, also must be equipped with automatic blowing device.The staple fibre that produces during fiber aggregate is mixed in broken end and inhales in the cotton in addition, and is unfavorable to reuse.Moreover,, having elongated the distance of front roller center to rail spindle installed surface so duct cross-section is long-pending greatly, highly high because of inhaling cotton air channel and gathering the air channel and unite two into one, the balloon shape when causing yarn from the guide dog hole to the rings twisting winding and tension force change are greatly.
Summary of the invention
The purpose of this utility model provides frequency conversion fan of a kind of usefulness that the negative pressure of inhaling cotton and gathering is provided simultaneously, and volume is little, energy-conservation, the vibration damping noise abatement, can improve the constant ring ingot negative pressure type compact spinning fine spining machine air box that gathers negative pressure.
The utility model is that the technical scheme that achieves the above object is: a kind of ring ingot negative pressure type compact spinning fine spining machine air box, it is characterized in that: comprise air box and frequency conversion fan, be provided with negative pressure cabin and cabinet in the described air box, described negative pressure cabin comprises the transition negative pressure cabin that gathers negative pressure cabin and communicate with it, be installed in its inlet scoop of frequency conversion fan in the cabinet with the transition negative pressure cabin or gather negative pressure cabin and communicate, the place, inlet scoop of frequency conversion fan is equipped with and gathers filter screen, at least one gathers the air channel and gathers negative pressure cabin and communicate, being installed in one of them B/P EGR Back Pressure Transducer EGR that gathers on the air channel is connected with frequency conversion fan by frequency converter, the transition negative pressure cabin is inhaled cotton air channel with at least one and is communicated, in each transition negative pressure cabin negative pressure regulating mechanism is installed, and transition negative pressure cabin or inhale air draught front portion that cotton air channel is positioned at negative pressure regulating mechanism and be equipped with and inhale cotton filter screen.
The utility model is provided with a frequency conversion fan, one and gathers negative pressure cabin and transition negative pressure cabin in air box, because at least one gathers the air channel and gathers negative pressure cabin and communicate, communicate with the transition negative pressure cabin by negative pressure regulating mechanism and inhale cotton air channel, the cotton negative pressure of suction can be provided simultaneously and gather negative pressure by a frequency conversion fan, therefore can reduce the volume of bellows, energy-conservation, reach the effect of vibration damping noise abatement, the influence of counter extensioin drive disk assembly can not only be reduced, and working environment can be improved.The pressure sensor that the utility model will gather on the air channel is connected with frequency conversion fan by frequency converter, therefore can change according to the pressure that gathers on the air channel, regulate the rotating speed of frequency conversion fan, it is constant to guarantee to gather negative pressure setting pressure maintenance on demand, can reach to energy-conservation again.The utility model is provided with respectively and gathers filter screen and inhale cotton filter screen, and long fiber in the time of can be respectively to brachycephaly and the staple fibre that gathers generation carry out reuse.The utility model adopts respectively and independently gathers the air channel and inhale cotton air channel, and it is long-pending to reduce the air channel section, and balloon shape in the time of can not producing yarn from the guide dog hole to the rings twisting winding and tension force become big problem.
