Abstract
The utility model is suitable for a filter rod making machine technical field provides an open ware, open ware is a bilateral symmetry's arch guide arm, and both ends are fixed with the support. The utility model provides an open ware simple and practical, low in cost need not to be equipped with the air -blower. The silk bundle launches effectually in practical application, has still reduced the maintenance cost when improving product quality.
Description
Technical field
The utility model belongs to filter-stick forming device technical field, particularly relates to a kind of loosening device.
Background technology
Loosening device is the low-pressure air current utilizing by-pass type blowing engine to produce, and the mono-filament portion of tow band is separated, tow is spread into required width equably, eliminates all and may appear at false twisting in tow, the fitfull distortion of combing tow and fold.Tow is through shredding, and then just enter plasticizer applied area by the expansion of main loosening device, if shredding is effective, tow is more even, more will be conducive to the applying of plasticizer.As shown in Figure 1, the loosening device of YL21 unit is divided into two-stage, and the first loosening device 11 is arranged on revoliving arm.After second loosening device 12 (main loosening device) is arranged on the second plucker roller 13.
In concrete production process, to the requirement of tow opening stent be: last one air-opening tow stent reaches 225 ± 25mm.Horizontal stent is even, without tow share split or became uneven phenomenon.Horizontal stent is as far as possible wide, but after can not causing shredding, both sides tow has overlapping phenomenon.The quality of tow opening stent is very large on filter rod quality impact.Because stent is bad, cause product design situation as follows:
1, when narrower tow band enters plasticising case, will produce plasticizer and spray uneven, plasticizer loading reduces, thus cause filter stick hardness and weight on the low side.
2, the wide expansion of tow band, so tow band will produce torsion, tension force suddenly big or suddenly small during flowing when flowing, and can not get alleviating, and the resistance to suction of filter stick and weight, will produce larger fluctuation.
As shown in Figure 2, comprise base plate 21 and cover plate 22, both are parallel, and gap is less, are generally about 2mm for the structure of current loosening device.Described base plate has along its length a narrow groove 23 of " people " font, and by-pass type blowing engine is set below base plate, blower outlet is communicated to bottom described base plate by an inverted trapezoidal air channel, blowing engine produces low-pressure air current from the narrow groove blowout of chevron pointing, and tow is spread into required width equably.The airshed that blowing engine produces is non-adjustable, and when running into the tow of different qualities, air quantity can not meet the demand of tow characteristic, and the tow stent that can cause is roomy, and some tow stents are narrow, remote effect product design.Time not parallel when between upper and lower two plates of loosening device, can produce tow and run monolateral, and stent be wide not, easily cause plasticizer to spray uneven, the half of soft one side of something of filter stick is hard.When two plate intervals are too large, stent can be produced narrow, on the similar loosening device air deficiency of the impact of product design.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of loosening device, is intended to solve that existing loosening device cost is high, the technical matters required of can not ensuring the quality of products.
The utility model adopts following technical scheme:
Described loosening device is an axially symmetrical arch guide rod, and two ends are fixed with support.
Described arch guide rod two ends are provided with screw thread, and arch guide rod two ends are through fastening with nut after the support of respective side.
Described support is provided with vertical rectangular slotted eye, and described arch guide rod two ends are fastening with nut through the slotted eye on the support of respective side, and described arch guide rod two ends are in sustained height.
Further, described support is L-type.
Further, described arch guide rod is corrosion-resistant steel guide rod, guide rod periphery rounding off.
Further, the sagitta of described arch guide rod is 100mm.
The beneficial effects of the utility model are: the loosening device that the utility model provides is an arch guide rod, and without the need to arranging blowing engine, with low cost, very easy to use, very little by ectocine, tow opening is effective.
Accompanying drawing explanation
Fig. 1 is tow air-opening procedure chart;
Fig. 2 is the exploded view of existing loosening device;
Fig. 3 is the constructional drawing of the loosening device that the utility model provides;
Fig. 4 is the using state figure of the loosening device that the utility model provides.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
In order to technical scheme described in the utility model is described, be described below by specific embodiment.
Fig. 3 shows the structure of the loosening device that the utility model embodiment provides, and illustrate only the part relevant to the utility model embodiment for convenience of explanation.
As shown in Figure 3, the loosening device that the present embodiment provides is a symmetrical arch guide rod 3, and two ends are fixed with support 4.Conveniently selection, described arch guide rod is corrosion-resistant steel guide rod, and a stainless steel strip be of convenient length can be adopted to bend and form, sagitta is 100mm, guide rod periphery rounding off.Arch guide rod two ends obtain screw thread by tapping, fix after then two ends being crossed the support of respective side with nut 5.The present embodiment limits the shape of support, is L-type in diagram.
With reference to Fig. 1, in current YL21 unit production process, tow through shredding, by entering plasticising case 14 after the expansion of main loosening device (the second loosening device 12).Therefore, in the present embodiment, arch guide rod is installed on the position of former second loosening device equally.First two supports are fixed on former second loosening device position, then support are passed at arch guide rod two ends, tighten finally by nut.Here to ensure that arch guide rod two ends are in sustained height.
Can control to realize tow stent, as a kind of preferred implementation, described support is provided with vertical rectangular slotted eye (not shown), and tightening nuts after slotted eye is passed at arch guide rod two ends also ensures that two ends height is identical.By unscrewing nut, the height of arch guide rod can be adjusted up and down, control stent with this.
The using state figure of the loosening device shown in composition graphs 4, tow band 41 is when arch guide rod 3, and centre portion is risen, and utilizes the pulling force in tow band operational process, and tow band is supportted uniformly by arch guide rod and launches, thus ensures the stable of shredding stent.
The comparison of configuration aspects, this loosening device is more simple and practical than original loosening device; Cost aspect, this loosening device is cheap, and existing loosening device cost is high, needs to be equipped with by-pass type blowing engine, and the damage and blowing engine easily generates heat, also can increase maintenance cost.The loosening device that the present embodiment provides, successful, also reduces maintenance cost while improving the quality of products in actual applications.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
