Description
Technical Field
The utility model belongs to the technical field of non-woven machine, concretely relates to spunlace machine goes into cotton layer forming device of thorn.
Background
The spunlace layer of the spunlace machine is a nonwoven fiber cotton layer formed before entering the spunlace machine, and the grammage of the nonwoven fiber cotton layer is 40g/m2Above, for example, 40 to 60g/m2And is suitable for use in the manufacture ofCan be used as sanitary materials such as dry tissue, warm tissue, cosmetic wiping tissue, facial mask dressing paper, etc.
As is known in the art, the aforementioned hydroentangled layers of spunlace introduced by hydroentangling are formed or configured by corresponding devices in a relatively rational arrangement.
Fig. 5 is a schematic view of a prior art spunlace machine batt layer forming device. As shown in fig. 5, a lower cotton layer carding machine 1, an upper cotton layer carding machine 2 and a spunlace machine 3 are sequentially distributed from left to right, nonwoven fibers combed by the lower cotton layer carding machine 1 and nonwoven fibers combed by the upper cotton layer carding machine 2 are conveyed to the spunlace machine 3 by a conveying curtain in an overlapped state, and spunlace is completed by the spunlace machine 3 and is dried, so that a nonwoven product is obtained.
Fig. 6 is a schematic illustration of a lower cotton layer 11 combed by the lower cotton layer carding machine 1 shown in fig. 5 and an upper cotton layer 21 combed by the upper cotton layer carding machine 2. The lower cotton layer fibers 111 of the lower cotton layer 11 are in a longitudinal state with respect to the position of the hydroentangling machine 3, and the upper cotton layer fibers 211 of the upper cotton layer 21 are also in a longitudinal state in the same way. The arrangement of the apparatus shown in fig. 5 and the configuration of the upper and lower cotton layers 21, 11 shown in fig. 6 are hydroentangled by the hydroentangling machine 3 and the resulting product, i.e. the nonwoven product, after hydroentangling has the following disadvantages: firstly, the operating speed of the hydro-entangling machine is generally high, and is 20-400g/m relative to the gram weight2The width is 3.5m and the water pressure is 40MPa, the production speed can reach more than 250-300m/min, so if the difference exists between the speed of the previous channel and the working speed of the spunlace machine, the waste of the energy for supporting the operation of the spunlace machine, such as the waste of the electric energy for supporting the operation of the mechanical moving part of the spunlace machine, the operation of the water pump of the spunlace machine, the drying of the drying device, the water treatment of the water treatment device and other equipment is quite large, thereby the product cost is increased, however, because the method in FIG. 5 belongs to a straight-combing straight-advancing spunlace machine, the drafting process or drafting link does not exist between the fiber cotton layer and the spunlace machine 3, and the speed difference between the fiber cotton layer and the spunlace machine is necessarily great; secondly, the fibers 211, 111 of the upper and lower cotton layers 21, 11 stacked together have a certain longitudinal tension but lack a transverse tension, so that the nonwoven product produced by the method is lack of transverse tensionThe transverse tension bearing capacity is poor, the actual use effect is influenced, and the due use value can not be even reflected.
Fig. 7 is another schematic view of a prior art spunlace machine batt-layer forming device. As shown in fig. 7, a lapping machine 4, a drafting machine 5 and a spunlace machine 3 are sequentially distributed from left to right, a single-layer cotton carding machine 6 is arranged behind the lapping machine 4, the single-layer cotton carding machine 6 and the spunlace machine 3 form an intersecting relationship, so the equipment configuration mode of fig. 7 is called a semi-interlacing mode in the industry, a fiber cotton web combed by the single-layer cotton carding machine 6 is conveyed to the lapping machine 4, and is drafted by the drafting machine 5 for 2.5-3 times and then is introduced into the spunlace machine 3 to complete spunlace.
Fig. 8 is a schematic view of a single cotton layer 61 combed by the single cotton carding machine 6 shown in fig. 7, the fibers of the single cotton layer 61 appear as transverse single cotton layer fibers 611 with respect to the hydroentangling machine 3, and the single cotton layer 61 is converted into a single drafted cotton layer 612 by being drafted by the drafting machine 5. The method shown in fig. 7 has the advantage of relatively fast speed due to the drawing by the drawing machine 5, but the strength of the nonwoven product after hydroentanglement by the hydroentangling machine 3 is very weak.
Fig. 9 is another schematic view of a prior art spunlace machine batt-layer forming device. As shown in fig. 9, a lapping machine 4, a drafting machine 5, an upper cotton layer carding machine 2 and a spunlace machine 3 are sequentially distributed from left to right, and a lower cotton layer carding machine 1 is arranged behind the lapping machine 4, because the lower cotton layer carding machine 1 is arranged behind the lapping machine 4 and because the upper cotton layer carding machine 2 is arranged at the right side of the drafting machine 5, the lapping machine 4 is substantially the lower cotton layer lapping machine, the nonwoven fibers combed by the lower cotton layer carding machine 1 are supplied to the lapping machine 4 to be lapped into a cotton web, the lapped cotton web is conveyed to the drafting machine 5 by a conveying curtain to be drafted, and after the nonwoven fibers are discharged from the drafting machine 5, the nonwoven fibers combed by the upper cotton layer carding machine 2 are covered to the passing cotton web (i.e. the lower cotton web) and introduced into the spunlace machine 3, so as to obtain a nonwoven product.
Fig. 10 is a schematic illustration of a lower cotton layer 11 combed by lower cotton layer carding machine 1 and an upper cotton layer 21 combed by upper cotton layer carding machine 2, as shown in fig. 9. The lower cotton layer 11 is drafted by the draft machine 5 to be converted into the lower cotton layer drafted cotton layer 112, and the upper cotton layer carding machine 2 is located at the right side of the draft machine 5, so that the lower cotton layer is not drafted, and the lower cotton layer fibers 111 are horizontal and the upper cotton layer fibers 211 are vertical, specifically, the upper and lower cotton layer fibers are vertically and horizontally staggered with respect to the position of the spunlace machine 3, so that the strength is improved with respect to fig. 6 and 8, but the strength is still not enough to meet the strong requirement expected in the industry, and although the lower cotton layer 11 is drafted by the draft machine 5 to be converted into the lower cotton layer drafted cotton layer 112, the draft multiple is only 2.5 to 3 times in a normal condition, so that a significant speed difference with the spunlace machine 3 with a high speed still exists.
Based on the above-mentioned factors, the problem of how to make the forming device of the stab-cotton layer to increase the forming speed of the stab-cotton layer to be adapted to the water-jet speed of the water-jet machine and to ensure sufficient strength of the nonwoven product water-jet by the water-jet machine has long been troubled and is expected to be solved, but there is no corresponding technical teaching in the Chinese and foreign patent documents disclosed so far, and the technical solution to be described below is generated in this context.
In view of the above-mentioned technical problems of the prior art in the preparation of nonwoven articles, it is necessary to search for and reasonably improve the technical solutions described below.
