The utility model relates to the suction silk mouth of inhaling silk device in a kind of textile machine, specifically, is a kind of being used for the chemical fibre waste silk of spinning process to be sucked the suction silk mouth of inhaling in the silk device.

Two, background technology

False twist texturing machine in spinning process, need be with chemical-fibres filaments by winding mechanism around to bobbin, to finish the coiling of silk thread.After a bobbin is completely rolled up, just need more change of bobbins, must cut off long filament this moment, wait until that new bobbin installs after, again with tow around to new bobbin.Owing to more than 200 winding bobbin arranged on a Texturing Machines, the multi-filament line is promptly arranged, more during change of bobbins, other ingot position also will work on, so can not shut down an ingot position.When change of bobbins more, the silk thread of being cut off is still constantly carried from roller and is come, and just needs this moment to inhale silk device by one, to store in the long filament suction wire storage cylinder of sending here, prevent silk accumulation winding, to guarantee bobbin arranged certain replacing time, and repiece is reeled smoothly.

In inhaling silk device, it is crucial inhaling the silk mouth, and it is an inlet of drawing waste silk, and its quality will be directly connected to the effect of whole suction silk device.In traditional suction silk device, more during change of bobbins, each is not inhaled silk mouth and relies on plug sealing of self, and the air and the external world that are attached thereto in the suction silk wire passage that connects are separated, to guarantee to inhale negative pressure in the wire passage.During work, plug is pushed, to inhale the silk mouth mouth of pipe opens, make in the whole pipeline and produce negative pressure by inhaling a silk blower fan, impel inner air tube to flow, the silk thread of bringing this moment, is inhaled the silk mouth and is resealed after work is finished along with flowing through of air inhaled the silk mouth, a suction silk wire passage is inhaled in the wire storage cylinder.Because the negative pressure that the motion of waste silk relies on the running of suction silk blower fan to be produced realizes, so the movement velocity of waste silk depends on the watt level of inhaling the silk blower fan.The operation of a machine speed is more and more higher at present, and the movement velocity of waste silk is also more and more faster, reached more than 1000 meters/minute, thereby the power of suction silk blower fan is also more and more higher, and energy consumption is also more and more.Inhale in the silk process, because the resistance of tow changes, beginning that just waste silk is sucked the silk mouth and again during repiece, resistance is bigger, and is bigger to the requirement of negative pressure, all the other times are then less, vacuum magnitude is identical from the beginning to the end for traditional suction silk device, do not change, and be prerequisite to satisfy the tow maximum resistance during design, at tow resistance hour, the waste of energy is very big like this.

Three, summary of the invention

The purpose of this utility model provides and a kind ofly can suck waste silk and inhale that silk is effective, energy consumes low suction silk mouth.

The purpose of this utility model realizes by following technical proposals:

A kind of suction silk mouth that is used for inhaling silk device, comprise and inhale the silk passage, be provided with shred suction opening on the top of inhaling the silk passage, it is characterized in that: described suction silk passage is divided into two sections, be provided with switch base between two sections, this switch base can make a two sections suction silk passage communicate or cut off.

When plug slides in slideway, inhale a silk passage and communicate or cut off in order to realize two sections better, in slideway, be positioned at range place, the plug left and right sides and be provided with plug and end the row projection.Plug is under piston action, and when being in end projection, two sections are inhaled the silk passage and communicated; Plug is under the effect of spring, and when being in other end projection, two sections are inhaled the silk passage and cut off.

At broken end with again during repiece, suck a silk mouth smoothly in order to make silk thread, be provided with auxilairy air intake at the hypomere of inhaling a passage.Auxilairy air intake can increase one air-flow that inwardly blows, to increase the suction to silk.And all the other times, the resistance of motion of waste silk is less, and this one air-flow just can be closed, and waste silk only relies on the effect campaign of inhaling the silk blower fan.

Compared with prior art, suction described in the utility model silk mouth be as long as less suction just can satisfy waste silk when sucking, and the plug in the switch base relies on the active force of spring to block hypomere to inhale a silk passage, seal, make and inhale a maintenance negative pressure in the silk wire passage; When the big suction of needs, switch base air inlet, a suction silk blower fan, auxilairy air intake are opened simultaneously, compressed air enters the switch base air inlet, the promotion piston moves, make the plug holddown spring, through hole on the plug is communicated with a two sections suction silk passage, guarantee that silk thread sucks in the wire storage cylinder smoothly.Its advantage is: simple in structure, low in energy consumption, to inhale silk effective.
