Background technology
Traditional ring spinning yarn technology has had the developing history of decades in China, but because its more structural problems, determined the fiber strip after drafted between the twisting point, to have a spinning triangular zone at front roller nip, fibre bundle in this trigonum after drafted is flat bar shaped, the edge fiber is without any constraint, thereby wherein a part of edge fiber one end or all break away from the main fibre bundle and form filoplume and flyings, filoplume produces bigger negative effect to later process, and flyings pollute workshop the working environment of workers.Most edges fiber not exclusively stretches when advancing to the twisting point, so they are little and cause yarn strength to be difficult to improve to the yarn strength contribution, thereby influences weaving efficiency.In order to solve this difficult problem, in recent years, a kind of compact frame spinning yarn machine of numerous and confused both at home and abroad release, this equipment mainly by negative-pressure air-flow be used for control front roller nip to the fibre bundle between the twisting point, reduce even eliminate the spinning triangular zone of ring spinner, thereby make yarn strength improve, fibrous index improves greatly.
The negative-pressure air-flow route generally is by discharging behind the parts such as compact spinning apparatus, air channel, filter, negative pressure centrifugal blower.Because the special working environment of textile mills, after deposition short flannel amount surpassed some on the filter, the required insufficient pressure of compact spinning apparatus and influence yarn quality was when the short flannel deposition can cause the blower motor overload and burn motor when seriously in time not clearing up.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of negative pressure control apparatus of simple, reliable compact spinning negative pressure system is provided, to guarantee compact spinning apparatus negative regulation in the spinning process, be lowered into the difference of yarn quality, eliminate blower motor overload phenomenon and take place.
The purpose of this utility model is achieved in that the negative pressure control apparatus of a kind of compact spinning negative pressure system, this device comprises the negative pressure centrifugal blower, blower motor, the blower motor frequency converter, filter and air channel, described negative pressure centrifugal blower, filter and air channel are linked in sequence successively and communicate, be characterized in: the end in the air channel away from the negative pressure centrifugal blower adds pressure sensor and warning device, described pressure sensor and blower motor frequency converter carry out both-way communication, pressure sensor and warning device carry out one-way communication, set a pressure limit to pressure sensor, this scope is exactly the required range of negative pressure of compact spinning apparatus, pressure sensor with closely spin the main frame relay and carry out one-way communication.
After cotton short flannel deposit thickness reaches some on the negative pressure system filter, pressure is brought down below pressure sensor and sets down in limited time sensor output signal fan motor frequency converter, the rising of frequency converter output frequency in the air channel, motor rotary speed increases, and operating pressure raises; Operating pressure still is lower than the pressure sensor setting down in limited time when the frequency converter output frequency is elevated to frequency converter setting highest frequency, sensor output signal is to warning device, warning device is reported to the police automatically, this moment is if in time clean out filter, then pressure sensor outputs signal to warning device, and warning device automatically terminates warning; Continuity was not cleared up filter after five minutes if report to the police, and then pressure sensor outputs signal to the main frame relay, closely spinning equipment outage automatic stop.
By utilization of the present utility model, can well guarantee compact spinning apparatus at whole spinning process negative regulation, therefore can guarantee whole spinning process negative regulation, guarantee the stability of yarn quality.Can play a good protection to blower motor again simultaneously.
Description of drawings
Fig. 1 is the negative pressure control apparatus schematic diagram of the utility model compact spinning negative pressure system.
Among the figure: negative pressure centrifugal blower 1, blower motor 2, blower motor frequency converter 3, filter 4, air channel 5, warning device 6, pressure sensor 7.
The specific embodiment
Figure 1 shows that the negative pressure control apparatus of the compact spinning negative pressure system that the utility model is related, this device mainly is made up of negative pressure centrifugal blower 1, blower motor 2, blower motor frequency converter 3, filter 4, air channel 5, warning device 6 and pressure sensor 7.Described negative pressure centrifugal blower 1, filter 4 and air channel 5 are linked in sequence successively and communicate, described pressure sensor 7 and warning device 6 are installed at the end of air channel away from the negative pressure centrifugal blower, pressure sensor 7 carries out both-way communication with blower motor frequency converter 3, and pressure sensor 7 carries out one-way communication with warning device 6.
In the compact spinning negative pressure system, under the effect of negative pressure centrifugal blower 1, the negative-pressure air-flow flow direction is: air communication is crossed compact spinning apparatus and is entered air channel 5, filter 4, bellows and the 1 back discharge of negative pressure centrifugal blower successively.Because this negative pressure system is used for textile mills, the characteristics of particular job environment such as flyings, dust and cotton short flannel be many in the workshop and equipment, air channel 5 length are longer, so pressure sensor 7 is installed in the most tangible end away from negative pressure centrifugal blower 1 of negative pressure variation, pressure sensor 7 and blower motor frequency converter 3 carry out both-way communication, form closed-loop control system.Pressure sensor 7 carries out one-way communication with warning device 6, and sensor 7 outputs signal to warning device 6, controls it and whether reports to the police.The online at any time detection of pressure sensor air channel terminal pressure size also outputs signal to blower motor frequency converter and warning device.
According to the spinning process requirement, the compact spinning apparatus negative pressure must remain on the stability that a reasonable range could guarantee yarn quality.In order to ensure yarn quality, set the range of negative pressure of working in the air channel by pressure sensor 7.Flyings, dust and cotton short flannel enter air channel 5 by compact spinning apparatus in the workshop, under the effect of negative pressure centrifugal blower 1, finally they are deposited on the negative pressure system filter 4, when deposit thickness reaches some, because the filter Air permenbility reduces, negative pressure centrifugal blower 1 air inflow reduces, the air channel internal pressure descends, when dropping to pressure sensor 7, pressure sets down in limited time, pressure sensor 7 outputs signal to blower motor frequency converter 3, require frequency converter 3 output frequencies to raise, blower motor 2 rotating speeds improve, the corresponding rising of operating pressure.But the frequency converter output frequency is not unrestrictedly to improve, the highest output frequency of frequency converter is according to the blower fan system performance setting, if blower motor 2 rotating speeds are mentioned the highest, when the work negative pressure still can not meet the demands the spinning process requirement, at this moment, blower motor frequency converter 3 goes out signal and gives pressure sensor 7, and acquisition request reduces the signal of frequency, prevents the running of blower motor long term overloading and burns.Pressure sensor outputs signal to warning device 6 simultaneously, and warning device 6 is reported to the police after receiving signal automatically, requires the related work personnel to clear up the cotton short flannel of deposition on the filter 4.The also not cleaning in five minutes if report to the police, pressure sensor outputs signal to the main frame relay, the main frame parking of cutting off the power supply automatically, thus avoid a large amount of yarn production off quality to come out.When the cotton short flannel of cleaning out on the filter, restart main frame after, whole system comes back to the preliminary examination state.In time clear up filter within reporting to the police five minutes at warning device, then pressure sensor 7 outputs signal to warning device 6 and removes warning, and equipment runs well.
