Description
Technical Field
The invention belongs to the technical field of non-woven machinery, and particularly relates to a non-woven fiber web cotton pressing device.
Background
As known in the art, a production apparatus for a set of nonwoven products such as nonwoven fabrics, nonwoven mats, etc. mainly includes an opener, a carding machine, a lapping machine, and a needle machine or a hydroentangling machine, nonwoven fibers are opened by the opener and supplied to the carding machine, nonwoven fibers after being carded by the carding machine are supplied to the lapping machine to be lapped, and the lapping machine is supplied to the needle machine to be needled or the hydroentangling machine to be hydroentangled to form a nonwoven product.
The foregoing carding machines are not known in the published chinese patent literature, such as grant publication No. CN1313660C (flat card with multiple feeds of fibers in the form of fiber mats), CN2816061Y (full-fixed flat card), CN100510211C (feeding and carding system of a card), CN105648582A (carding apparatus for a nonwoven fiber), CN104312788a (a high performance fiber carding machine for carding blend fabrics and carding method thereof), CN102505201C (roller flat card), CN104153045A (new card), CN202671747U (nonwoven high speed random card), CN202671748U (nonwoven high speed random output card), CN200958134Y (carding apparatus of a card), CN103225137a (a single cylinder double doffer card) and CN202466005U (nonwoven card), and so on.
The foregoing lapping machine is also not inadequately seen in the published chinese patent literature, and examples thereof are CN2637519Y (lapping machine), CN100554539C (lapping machine with compensation function), CN101168871a (lapping machine with compensation function), CN201272889Y (cross lapping machine), CN101671919B (an interlaced lapping machine), CN103221591B (cross lapping machine), CN103710884A (cross lapping machine and method for operating the same), CN104695136a (cross lapping machine) and CN205529360U (a lapping machine for mass production of nonwoven material), and the like.
From a reading of patent documents not limited to the examples above, it is known in combination with the expert knowledge in the art that: the nonwoven fibers combed by the carding machine are conveyed to the lapping curtain of the lapping machine by the cotton conveying curtain of the carding machine, namely, the lapping curtain of the lapping machine is used for receiving the nonwoven fibers from the cotton conveying curtain of the carding machine and supplying the received nonwoven fibers to the lapping trolley, the nonwoven 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 needling machine.
As is known in the art, during the actual operation of the nonwoven plant, the speeds of the carding machine, the lapping machine, etc. must also be adapted to the increasing speeds of the needling machine, since it is not possible and cannot achieve a seamless butt joint between the card clothing curtain of the structural system of the carding machine and the lapping curtain of the structural system of the lapping machine, with only a differential spacing therebetween. In the process that the cotton conveying curtain of the carding machine conveys the nonwoven fibers to the lapping curtain and the lapping curtain spreads the nonwoven fibers to the lapping curtain under the high-speed motion of the lapping trolley, the nonwoven fiber web can generate a phenomenon of floating upwards in a bordering area between the cotton conveying curtain of the carding machine and the lapping curtain, so that the nonwoven fiber web spread on the lapping curtain by the lapping machine is loosened, the strength of the web spread on the lapping curtain is influenced, and finally the quality of a needled or spun-laced nonwoven product is influenced. In particular, the degree of floating and loosening of the web is proportional to the speed, for example, the nonwoven web floats relatively lightly at a web laying speed of 40m/min, but as the speed increases, for example, from 40m/min to 100m/min, the web floats extremely severely or even fails to achieve web laying.
The technical problems are very limited to the processing speed of the nonwoven products, and particularly the industry always desires to solve the problems, but the technical proposal to be described below is generated under the background that the prior art and the prior art do not see the reference to solve the technical problems.
