" filter tow " speech is meant the ulotrichy material that is made of many curling fibers, for instance, is the ulotrichy material that is made of synthetic spinning fibre.
For instance, filter tow can be made of the fiber of the cellulose acetate, the particularly cellulose that curl-2.5-acetate spinning,
Known manufacturing cigarette equipment with filter tip generally is made of pretreatment unit and processing unit (plant).
Pretreatment unit generally be provided with the filter tow broadening, loose, extend and various mechanisms such as loose again, add at needs under the situation of softening agent, also be provided with the mechanism of the filter tow that constitutes with the moistening spinning fibre of softening agent.
Processing unit (plant) generally is provided with the feeding mechanism of assembling filter tow, this mechanism has feed hopper and tube is enclosed in charging, under need are wrapped in filter tow situation in the cigarette paper strip, also be provided with package mechanism, be provided with in addition the tobacco smoke filter element billot is cut into the mechanism that single tobacco smoke filter element is chewed.
The equipment that known manufacturing tobacco smoke filter element is chewed, on the filter tow direction of motion, also be provided with filter tow charging mould in the front of feed hopper, in this case, on the wall body of feed hopper, be provided with steam vent, make the gas (being preferably air) that enters by the charging mould, can from feed hopper, overflow.
Known to general, make in the method and apparatus of cigarette, filter tow continuously, for instance, be to constitute by the cellulose-2.5-acetate spinning fibre that curls, earlier that spinning fibre is stacked layer by layer before the work, suppress balling-up again, during work filter tow is continuously extracted out from sphere, make its broadening, walk around roller or similar ways, broadening again, by the retardance roller, extend, loose, broadening again, to its spraying softening agent, and make it walk around slewing rollers, by the charging mould, enclose tube by feed hopper and charging again, be wrapped in case of necessity in the cigarette paper strip and form the tobacco smoke filter element billot, cut into directly available tobacco smoke filter element at last and chew.
Filter tow is extended processing can make curling spinning fibre be separated from each other.
In the loose process afterwards, because its curling elasticity, filter tow shrinks once more and swells, can swell and depend on whether appropriate extension is handled, just extend and should not cross weak in order to avoid fiber can not all separate, but also should be not strong excessively, in order to avoid produce plastic deformation.
But the method and apparatus that this known manufacturing tobacco smoke filter element is chewed has following shortcoming:
-the movement velocity of filter tow raise with and the degree that swells also may raise the time, in the zone between slewing rollers and charging mould, friction between filter tow and the surrounding air will aggravate, forming folding tendency on slewing rollers will increase, and this means that filter tow is wrapped on the slewing rollers easily voluntarily.
For the filter tow that swells still can be pulled out from slewing rollers reliably, must strengthen the operating pressure of gas in the charging mould.
-air-flow (preferably air stream) is molded into feed hopper and tube is enclosed in charging with the filter tow that swells from charging.Air pressure in the charging mould is higher, is pressed into filter tow that charging encloses tube also the more, certainly, at first should correspondingly supply with more filter tow to pretreatment unit and extension mechanism.Enter charging and enclose the restriction system that the quantity of the filter tow of tube is subjected to following each side: frictional force, spinning fibre friction each other and the hardness of spinning fibre itself between the inwall is enclosed in filter tow and feed hopper inwall and charging.But, because the pressure in the charging mould and the quantity of feed hopper inner filtration fibre bundle have all increased, the uniformity (being equally distributed degree) that tobacco smoke filter element is chewed filter tow in the finished product will reduce, thereby the draw resistance of each filter tip on its whole length is also just very inconsistent each other.
-raise in running speed, when just filter tow passes through the speed rising of processing unit (plant), performance-material curve will shorten (performance-material curve is the relation curve between draw resistance and the filter tow consumption, and the filter tow consumption is meant at the manufacturing tobacco smoke filter element chews the quantity that the tobacco smoke filter element of making certain size on the device is chewed required filter tow).Certainly, this can remedy by the pressure that strengthens in the charging mould, this means that the gas pressure that improves in the charging mould can make performance-material curve lengthening, but as described above, the pressure that improves in the charging mould can make the draw resistance of each filter tip on its whole length very inconsistent each other.
Therefore be desirable to provide a kind of energy and satisfy the method that the following manufacturing tobacco smoke filter element that requires is chewed:
-raise and swelling may add very the time of filter tow in running speed, can prevent from slewing rollers, to form folding phenomenon, thereby can increase the pressure in the charging mould, even also can lower this pressure, or remove the charging mould at all from;
-can increase enter charging enclose the tube filter tow, corresponding increase tobacco smoke filter element is chewed the filter tow consumption in the finished product and is made filter tip have the draw resistance of uniformity, thereby can increase the interior pressure of charging mould, even also can lower this pressure, or remove the charging mould from all;
-when running speed raises, can make performance-material curve lengthening, make each tobacco smoke filter element chew the draw resistance uniformity of finished product simultaneously, thereby can improve the pressure in the charging mould, even also can lower this pressure, or remove the charging mould at all from.
Based on the processing method that this specification is proposed at the beginning, feature of the present invention is: make gas or steam become the angle less than 90 ° to act on the filter tow along the filter tow direction of motion with its longitudinal axis in feed zone.
