Technical Field

The invention belongs to the technical field of nonwoven machinery, and particularly relates to a nonwoven fiber web pressing device.

Background

As known in the art, a production apparatus for a set of nonwoven products such as nonwoven fabrics, nonwoven felts, etc. mainly includes an opener, a carding machine, a lapping machine, and a needle loom or a hydro-entangling machine, wherein the opener opens and supplies nonwoven fibers to the carding machine, the nonwoven fibers carded by the carding machine are supplied to the lapping machine for lapping, and the lapping machine after lapping is supplied to the needle loom for needling or hydro-entangling to form the nonwoven products.

The aforementioned carding machines are not known in the published chinese patent literature, such as the grant publication No. CN1313660C (flat card for multi-feeding fibers in the form of a fiber mat), CN2816061Y (full-fixed flat card), CN100510211C (a feeding and carding system of a carding machine), CN105648582A (a carding device of nonwoven fibers), CN104312788A (a high-performance fiber carding machine for carding a union fabric and a carding method thereof), CN102505201C (roller flat hybrid card), CN104153045A (new card), CN202671747U (nonwoven high-speed random card), CN202671748U (nonwoven high-speed random output card), CN200958134Y (carding unit of card), CN103225137A (a single-cylinder double-channel card) and CN202466005U (nonwoven card), and so on.

The aforementioned lapping machines are also not known in the published chinese patent literature and are to be taken as a short list such as CN2637519Y (lapping machine), CN100554539C (lapping mechanism with compensation function), CN101168871A (lapping mechanism with compensation function), CN201272889Y (cross lapping machine), CN101671919B (cross lapping machine), CN103221591B (cross lapping machine), CN103710884A (cross lapping machine and method for operating the cross lapping machine), CN104695136A (cross lapping machine) and CN205529360U (lapping machine for batch production of nonwoven), etc.

From a reading of the patent literature, which is not limited to the above list, and in combination with the expert knowledge in the field: the non-woven fibers combed by the carding machine are conveyed from a carding machine cotton conveying curtain of the carding machine to a lapping curtain of a lapping machine, that is, the lapping curtain of the lapping machine picks up the non-woven fibers from the carding machine cotton conveying curtain and supplies the picked-up non-woven fibers to a lapping trolley, the non-woven fibers are laid on the lapping curtain in a plurality of S-shaped forms by the reciprocating motion of the lapping trolley, and the lapping curtain is conveyed to the needle machine.

As is known in the art, in the actual operation of nonwoven plants, the speeds of carding machines, fleece layers and the like must be adapted to the increasing speeds of needling machines, which are not possible and are not able to be seamlessly joined to the fleece layers of the fleece layer structure, which are spaced apart only to a certain extent. Therefore, in the process that the non-woven fibers are conveyed towards the lapping curtain by the cotton conveying curtain of the carding machine and the non-woven fibers are lapped to the lapping curtain by the lapping curtain under the high-speed motion of the lapping trolley, the non-woven fiber cotton net can float upwards in a bordering area between the cotton conveying curtain and the lapping curtain of the carding machine, so that the non-woven fiber cotton net paved on the lapping curtain by the lapping machine is loosened, the strength of the cotton net paved on the lapping curtain is influenced, and the quality of a needle-punched or spunlaced non-woven product is finally influenced. In particular, the degree of floating and loosening of the web is proportional to the speed, and the floating of the nonwoven fiber web is relatively slight, for example, at a laying speed of 40m/min, but with increasing speed, for example, gradually increasing from 40m/min to 100m/min, the floating of the web is extremely severe, and even the laying cannot be achieved.

The above technical problems are serious limitations on the processing speed of nonwoven products, and in particular, the solution is always desired in the industry, but there is no reference in the published Chinese and foreign patent documents to solve the above technical problems, and the technical solutions to be described below are generated in this context.
