Description
Technical Field
The invention belongs to the technical field of auxiliary equipment in a complete production line of nonwoven products, and particularly relates to a nonwoven fiber web compensation device matched with a lapping machine.
Background
As a complete production line of nonwoven products, there are generally known, from main equipment, a bale opener, a cotton blend weighing machine (a cotton blend weighing machine may be omitted if it is a single type of fiber), a carding machine, a lapping machine and a needling machine (a hydroentangler may also be used), nonwoven fibers which have been opened by the bale opener are supplied to the cotton blend weighing machine, then supplied to the carding machine for carding, then supplied to the lapping machine for laying up into a web layer, and then supplied to a needling machine for needling by a conveying device such as a conveying curtain or for hydroentangling by a hydroentangling machine to obtain nonwoven products.
According to the common general knowledge, and in terms of the process flow, since the lapping machine is necessarily located before the needling machine or the hydroentangling machine, the lapping machine belongs to a preceding apparatus with respect to the needling machine or the hydroentangling machine, and the process of feeding the nonwoven web laid from the lapping machine to the needling machine or the hydroentangling machine for needling or hydroentangling is generally not limited to the following cases as exemplified: firstly, a nonwoven fiber web formed by laying is sequentially drafted by a drafting machine by a bottom curtain of a lapping machine, and then is needled by a needling machine by a feeding machine; secondly, the nonwoven fiber web formed by laying is sequentially drafted by a drafting machine by a bottom curtain of a lapping machine, and then is conveyed to a hydroentanglement machine by a conveying curtain; thirdly, the non-woven fiber web formed by laying is supplied to a feeder by a bottom curtain of the lapping machine, and then is fed to a needle feeder by the feeder.
As is also known in the art, the lapping carriage of the lapping machine reciprocates side-to-side and the speed of the lapping carriage is suitably slowed down when the left and right end points are reversed (also referred to as "redirected") or returned, and correspondingly faster in the remaining areas. That is, there is a repetitive alternating process of slow to fast and then fast to slow web laying speed. In the period of time when the speed is changed from fast to slow, there is often unavoidable web redundancy, if the redundant web generated by the slow speed of the small speed of the web is not temporarily stored and the temporarily stored web is digested or released when the speed of the small speed of the web is increased, the laid fiber web will show inconsistent thickness difference between two ends (two sides) and the middle, and the quality of the nonwoven product after needling is affected.
The "lapping machine with compensation function" recommended in chinese patent CN100554539C can make the web laid by the lapping trolley take the shape of bread with thin middle thick two ends (also called "two sides"), because it can temporarily store the excessive fiber web when the lapping trolley stops or significantly decelerates at the left and right ends, and release the previously stored fiber web during the reverse movement of the lapping trolley, that is, compensate the excessive fiber web to the middle, thereby providing a guarantee for improving the consistency of the gram weight of the nonwoven product obtained by needling with the needling machine. However, since the web compensating device of this patent is directly coupled to the lapping cart, and in particular, a second web compensating device is provided on the lapping cart opposite the direction of movement of the first web compensating device and coupled to the first and second conveyor curtains and the pair of traction ropes, the overall structure of the lapping mechanism is relatively complex and the manufacturing cost is also significantly increased.
CN104755666B provides "compensating means for fluctuating transport speeds of the fibre web" as a relatively independent compensating means between the feed side and the discharge side, free from the conventional lapping carriage, thus avoiding complicating the construction of the lapping carriage with respect to CN 100554539C. However, because the compensation mode of the compensation device to the fiber web is that the fiber web is compensated at a fluctuating conveying speed and in a suspension type, the suspension type compensation generates more severe shaking to influence the stable consistency of the advancing track of the fiber web, the trimming effect and the uniform effect of the two sides of the laid fiber web layer can be influenced, and finally the quality of the needled non-woven product is difficult to ensure. The root cause of the jitter generated by the aforementioned CN104755666B is: frequent reversing of the lapping carriage causes the speed of the bottom curtain accompanying the movement of the lapping carriage to also change correspondingly frequently as speed increases and decreases (i.e. "changes in speed").
