Abstract
The invention provides a self-leveling device for crossly lapping fiber webs in non-woven fabric processing, which relates to a cross lapping machine for the fiber webs in the non-woven fabric processing. The self-leveling device is arranged on a web conveying curtain on the front part of a lapping trolley of the cross lapping machine, and comprises a pair of traction rolls which are arranged above the web conveying curtain in parallel and are vertical to a running direction of the fiber webs, wherein one traction roll is in fluctuating regular accelerated, decelerated or constant rotation relative to the rotation speed of the other traction roll. The self-leveling device greatly improves the transverse thickness consistency of the breadth of a non-woven fabric, avoids the condition that the thickness of both sides is greater than that of the middle part, greatly improves the quality of products, and can make the middle part and both sides of the lapped fiber webs uniform.
Description
Technical field
The present invention relates to fibre web intersection shop machine in the nonwoven fabric processing, relate in particular to the evereven that the fibre web intersection is spread out and put in the nonwoven fabric processing.
Background technology
In nonwoven fabric processing, always Yan Xu lapping operation be with fibre web by defeated lace curtaining input cross lapping machine, the dolly in the utilization cross lapping machine drops on one and fibre web traffic direction with fibre web with swinging and is on 90 ° of straight-line conveyers; From conveyer output be exactly the cross layered semi-finished product of continuity, again through water thorn, oven dry the nonwoven fabric finished product.There is an insoluble always problem in this processing method that continues into the present, exactly in swing is spread out and put on, trolley travelling near two ends the time, deceleration is arranged--acceleration---linear uniform motion process.Because the upwards of movement of the fibre web that defeated lace curtaining, dolly self rolling are carried is a definite value, slowing down--" overfeeding " can appear in the semi-finished product that-accelerating sections is layered in the conveyer both sides, cause half-finished thickness of two sides greater than interior thickness, the thick phenomenon in intermediate thin both sides also can appear in final nonwoven fabric, has a strong impact on product quality.Sometimes in order to allow the client accept product, can only the part that both sides are thick remove again, need add large format processing, cause great waste.
Summary of the invention
The present invention is directed to above problem, a kind of compactedness of passing through the local paragraph of material of change continuous feed is provided, thereby avoid the stacked evereven that the fibre web intersection is spread out and put in the nonwoven fabric processing that man-hour occurs " overfeeding " phenomenon that adds.
Technical scheme of the present invention is: it is arranged on the defeated lace curtaining of intersection shop machine lapping dolly front portion, it comprises a pair of carry-over pinch rolls, a pair of carry-over pinch rolls are set in parallel in defeated lace curtaining top, vertical with the fibre web traffic direction, one of them carry-over pinch rolls regularly accelerates, slows down with being pulsation with respect to the rotating speed of another carry-over pinch rolls or constant speed is rotated.
Described a pair of carry-over pinch rolls are carry-over pinch rolls one, carry-over pinch rolls two, carry-over pinch rolls one are towards the approach axis of fibre web, the rotating speed of carry-over pinch rolls two according to the position of lapping dolly automatically be pulsating quickening, slow down, when the lapping dolly entered the tow-away zone at two ends, the rotating speed of carry-over pinch rolls two was greater than the rotating speed of carry-over pinch rolls one; When the lapping dolly entered the linearity sector at middle part, carry-over pinch rolls two were consistent with the rotating speed of carry-over pinch rolls one.
The present invention has changed in the past in the equipment the at the uniform velocity situation of equivalent feeding of fibre web, on defeated lace curtaining, be provided with a pair of speed change carry-over pinch rolls, change the compactedness of fibre web self by the velocity variations of one of them carry-over pinch rolls, that is to say, fibre web enter the swing spread out and put on before, sectional " light filling bar " arranged on length, and this " light filling bar " is corresponding with the turning circle that enters deceleration of lapping dolly.When so just having overcome dolly and slowing down, the equivalent fibre web is fed and the overfeeding phenomenon that causes continuously, finally be reflected on the product, the breadth of nonwoven fabric transversely consistency of thickness improve greatly, avoided the situation of thickness of two sides greater than the middle part.Improved the quality of product greatly.Increase the cross lapping machine of apparatus of the present invention, thereby reach the drawing-off that changes fibre web, finally reach in the middle of the fibre web after stacked and the both sides uniformity by the speed ratio that changes by servo-controlled drawing roller one and drawing roller two.

The specific embodiment
The present invention as shown in Figure 1, 2, it is arranged on the defeated lace curtaining 1 of intersection machine 1 lapping dolly 6 front portions, shop, the defeated lace curtaining 22, it comprises a pair of carry-over pinch rolls, a pair of carry-over pinch rolls are set in parallel in defeated lace curtaining 1, defeated lace curtaining 22 tops, vertical with fibre web 7 traffic directions, one of them carry-over pinch rolls regularly accelerates, slows down with being pulsation with respect to the rotating speed of another carry-over pinch rolls or constant speed is rotated.
Carry-over pinch rolls 1 are towards the approach axis of fibre web 7, the rotating speed of carry-over pinch rolls 25 according to the position of lapping dolly 6 automatically be pulsating quickening, slow down, when lapping dolly 6 entered the tow-away zone 8 at two ends, the rotating speed of carry-over pinch rolls 25 was greater than the rotating speed of carry-over pinch rolls 1; When lapping dolly 6 entered the linearity sector at middle part, carry-over pinch rolls 25 were consistent with the rotating speed of carry-over pinch rolls 1.
Operation principle of the present invention is, fibre web 7 is carried by defeated lace curtaining 1, defeated lace curtaining 22, running hours, according to lapping dolly 6 in indexs such as time of tow-away zone, both sides 8, speed, calculate the servomotor that drives carry-over pinch rolls 25 and when instruct its acceleration, after both couplings.Fibre web 7 between carry-over pinch rolls 25, the carry-over pinch rolls 1 is drafted, and the compactedness of this section fibre web 7 reduces (fibre web that just can corresponding enter tow-away zone 8).Like this, in stacked process, stacked material 9 consistency of thickness in the horizontal is improved.The stacked material 9 of output on the conveyer 10 becomes the uniform nonwoven fabric of thickness through the processing of water thorn.
