Description
Technical field
The utility model belongs to spun-bonded non-woven production technical field, specifically, relates to a kind of equal wind apparatus of lower suction channel of spun-bonded non-woven lapper.
Background technology
From macroscopic view, the production technology of Spunbonded Nonwovens can be divided into following step: spinning, the cooling drawing-off of air-flow, lapping, hot rolling, coiling.Lapping is just in time in middle position.And lapper completes the main machine of lapping just, in whole technical process, play the important function of forming a connecting link.The quality of lapper design directly determines the quality of lapping, the quality of one-tenth cloth.
Lapper is mainly made up of following components: main transmission part, deviation correcting device, idler roller parts, hot-pressing roller parts, carrying roller parts, pumping air channel parts and lace curtaining etc. form.
Wherein, existing pumping air channel adopts one-sided suction scheme mostly.Owing to adopting one-sided suction, if do not add other devices, at the blast of the fabric width direction of lapper by different, large from the negative pressure of the position close to pump orifice, negative pressure from the position away from pump orifice is little, therefore, need to pass through certain equal wind apparatus, make the blast of lower pumping air channel fabric width direction consistent.
Existing equal wind apparatus is by be provided with the different baffle plate in interval in fabric width direction, thereby the difference adjustment at the interval by baffle plate makes the different objects that reach even blast of its draught area.
1, adjust difficulty, after the guipure of need to dismantling, could adjust, can not in the time of normal production, adjust.
2, can not accomplish completely all wind.Blast deviation is larger everywhere.
3, the existence of baffle plate has increased resistance, and lower air draught blower fan wind load strengthens, and energy consumption is high.
It is because baffle plate is to adopt to be screwed, and move its position, guipure need to be taken apart, again looks for position fixing again, has no idea to adjust in the time of normal production.
And because the adjustment draught area of baffle plate is comparatively rough, so its equal wind effect is general, deviation is larger.Baffle plate is airfast simultaneously, has increased the systemic resistance in air channel, and the load of lower air draught blower fan is increased, and energy consumption increases.
Utility model content
The shortcomings such as the utility model has overcome equal wind apparatus of the prior art and adjusted difficulty, and all wind weak effect, energy consumption be large, provide a kind of equal wind apparatus of lower suction channel of spun-bonded non-woven lapper, and it can flexible modulation, and all wind is effective, energy consumption is little.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of equal wind apparatus of lower suction channel of spun-bonded non-woven lapper, comprise the porous plate and the baffle plate device that are arranged in lower suction channel, described porous plate is arranged at described baffle plate device top, the percent opening of described porous plate from one end to the other side reduces gradually, described baffle plate device comprises dividing plate some and that wind direction is parallel and the air flue between described dividing plate, the corresponding described air flue of through hole of described porous plate, described dividing plate comprises left elastic membrane and right elastic membrane, between described left elastic membrane and right elastic membrane, it is cavity, the affixed upper fixing element in upper end of described left elastic membrane and right elastic membrane, fixed part is provided with the compressed air inlet channel being communicated with described cavity, the affixed lower fixture in lower end of described left elastic membrane and right elastic membrane, described lower fixture is provided with the compressed air outlet passageway being communicated with described cavity, described compressed air inlet channel and compressed air outlet passageway are equipped with valve.
Further, described left elastic membrane and right elastic membrane are rubber membrane.
Further, in described dividing plate inner chamber, be provided with baroceptor, its force value can be read by external display.
Further, fixed part and lower fixture are metal material.
Compared with prior art, the beneficial effects of the utility model are:
The utility model has adopted the elastic membrane of expansible sectional area, by the adjustment of compressed air pressure, air flue between dividing plate is changed and to affect corresponding duct cross-section long-pending, and lower air draught blast corresponding to corresponding impact, thereby reaches the object of equal wind.
The adjusting of compressed air pressure can go to regulate by the size of the switching of air valve and switching, and its adjustment can be carried out without lapper being shut down, can carry out flexibly aborning.The variation of the sectional area between dividing plate is continuous simultaneously, air pressure in each dividing plate is adjustable separately, lower suction channel blast everywhere can be controlled to comparatively accurate scope, its equal wind is effective, air channel blast, wind speed otherness is everywhere little, make lower suction channel consistent in the transversely lower air draught power everywhere of lapper, be conducive to uniformity into the net.
Meanwhile, what the utility model amassed duct cross-section reduces to affect less, and the resistance of increase is also less, and energy consumption is less.
