Abstract

The utility model relates to a paper napkin processing device with the function of embossing. The back of a feed port along a paper napkin running path is provided with an embossing rolling shaft with or without a heating mechanism, a paper folding mechanism, a cutter shaft and an output mechanism, wherein, the embossing rolling shaft adopts the structural form that small mold gears are axially arranged and assembled on the shaft; the number of the teeth between each gear and/or the radial included angle can be different; for wet-type paper napkins, an immersion liquid groove and a squeezing mechanism are additionally arranged between the paper folding mechanism and the cutter shaft, and necessary and proper tension structures can be arranged.

Description

The paper handkerchief processing unit (plant)

The utility model relates to a kind of paper handkerchief processing unit (plant), applicable to dissimilar paper handkerchiefs such as common dry type or wet types with embossing function.

For the aesthetic feeling that increases various daily paper handkerchiefs such as napkin paper, disinfected paper napkin and improve comfort when using, roll out multi-form ridge design or pattern on the paper handkerchief of being everlasting.These embossing devices or equipment all include impression cylinder or several part-structures such as roll shaft, paper foldling mechanism and product output mechanism.For the wet type paper handkerchief, also be provided with medicine liquid spray usually on the paper handkerchief band path after paper foldling mechanism or soak into structure.Belong to middle as paper handkerchief and have plastic sheeting interlayer form, partly also can be provided with heating arrangement, the heat seal embossed one-step is finished at impression cylinder or roll shaft.Although the structure of said apparatus or equipment can have more difference, with regard to impression cylinder or roll shaft, what all adopt at present is the monolithic devices member, new cylinder of processing and manufacturing or roll shaft again when changing embossed pattern, and cylinder or the roll shaft changed are promptly scrapped.In addition, because embossing must be carried out in the mutual rotation of a pair of cylinder with the convex-concave surface that can cooperatively interact or roll shaft, therefore for the requirement on machining accuracy height of cylinder or roll shaft, there is error promptly can appear at the problem that two convex-concave surfaces in the mutual rotation process can not the phase scarf close slightly.Practice also shows, even under the normal condition, this has only the small size or the point-like at its one paddy place, peak to cooperate contact to also between the concavo-convex fit structure of impression cylinder or roll shaft more, influence decorative pattern on the paper handkerchief aesthetic feeling, comfort and heat seal firm degree and/or be pressed into holding time of pattern.

The purpose of this utility model is to provide a kind of simple in structure at above-mentioned situation, easy to manufacture, simultaneously can also change and adjust the embossing floral designs easily, and extrude pattern firm paper handkerchief processing unit (plant) more attractive in appearance, and have the broad applicability that energy processing various ways paper handkerchief is produced.

Paper handkerchief processing unit (plant) of the present utility model is on the basis that keeps present same device or equipment said structure and function, what impression cylinder or roll shaft adopted is the assembly structure form, promptly, constitute the number of teeth between each gear and/or radially angle can be identical or different by the fine module gear of on central shaft, arranging closely or with interval assembling vertically.Owing to adopted the impression cylinder or the roll shaft of this assembly structure form, can be only with the gear unit member of a few configuration by necessarily putting in order and/or radially after the angle combination, can obtaining needed different embossed pattern, very convenient flexible.Simultaneously because the kind of gear unit member is few, be easy to keep produce in batches by identical index and precision, be assembled into the problem that is difficult for taking place mismate behind the cylinder merit roll shaft, and also can realize making the total surface of concaveconvex structure can both contacted good fit relation.When producing the paper handkerchief of band plastic sheeting interlayer, add heating arrangement commonly used such as an electrothermal tube at above-mentioned impression cylinder or roll shaft position and can realize that heat seal and embossing finish synchronously.

For adapting to the production of wet type paper handkerchief, can add the immersion liquid groove of a seasoning thimerosal or other used soup on the paper handkerchief band path after the above-mentioned paper foldling mechanism of the utility model, the paper handkerchief band that folds is soaked into by soup by this groove.Should be provided with the squeezer that has an extruding roller bearing at least behind the immersion liquid groove, excess liquid in the paper handkerchief be extruded so that utilize once more.Because the paper handkerchief band after soaking into easily is elongated usually, for preventing the middle fold that takes place of advancing, the tension structure that appropriate format is set on its operation path is necessary, as have or do not have the regulating wheel or the tensioning shaft of elastic construction, or adopt transmission speed ratio to be slightly larger than the transmission mechanism etc. of paper handkerchief band movement velocity before the immersion liquid.

Below describe structure of the present utility model again in detail, but this example should be interpreted as it is qualification the utility model scope with example shown in the drawings.

The A-A view of Fig. 2 Fig. 1

Fig. 3 knurling rolls axle construction figure

As shown in the figure, this example is for producing the processing unit (plant) of the wet type paper handkerchief of being with the plastic sheeting interlayer.Behind the charging aperture 19 that has a pair of friction pulley, be disposed with a pair of embossing roll shaft 11 along paper handkerchief tape running path, paper foldling mechanism 12 has the cutting knife rotating shaft 5 and the product exit conveyor 15 of blade 3.Each rotatable parts drives through transition wheel 4, transition wheel 6, transition wheel 9 and transition wheel 10 respectively by motor 1 and decelerator 2.After paper foldling mechanism 12, be provided with an immersion liquid groove 14, in the groove and have one by gravity and suitable spring and the paper handkerchief band 22 that passes through can be made the regulating wheel 23 of suitable tensioning.On the paper handkerchief band path after immersion liquid groove 14, matching with transition wheel 9 is provided with one and extracts roller bearing 7, and its below is provided with soup backflash 13.What also cooperate with transition wheel 9 simultaneously has one to assist feed roller 8.Be provided with a heating tube 16 at embossing roll shaft 11 places.Embossing roll shaft 11 is served as reasons and is constituted along its fine module gear of axially closely arranging assembling successively, every two adjacent gears are respectively homotype and alternately arrange mutually with the even number gear 18 of the number of teeth with the odd number gear 17 and the homotype of the number of teeth, and radially angle therebetween can be the phase difference of half circular pitch or by other desirable form or rule setting.The raw material of tissue 20 that accompanies plastic sheeting 21 when the centre is after charging aperture 19 enters, behind embossing roll shaft 11, become by heat seal and extrude the paper handkerchief band 22 of floral designs, after paper foldling mechanism 12 folds, logical immersion liquid groove 14 soaks into soup, extracted by extruding roller bearing 7, soup flows back to immersion liquid groove 14 through backflash 13.Paper handkerchief band after extracting is delivered to cutting knife rotating shaft 5 places through auxiliary feed roller 8 and is cut into Len req, drops on the exit conveyor 15 and is sent packing.Be the variation of paper handkerchief strip length after the adaptation immersion liquid, regulating wheel 23 can be with the tensioning of paper handkerchief band appropriateness.In addition, also can be with the many teeth of the travelling gear number of teeth of the transmission gear ratio embossing roll shaft 11 of drive 9 and extruding roller bearing 7 and auxiliary feed roller 8, suitably improve the speed of service of paper handkerchief band after the immersion liquid, with avoid the paper handkerchief band because of length variations causes unsuitable fold.
