Abstract
The utility model provides a kind of filament compression roller reducing filament consumption, comprise top roll and lower roll, the roll surface that it is characterized in that one of them roller in described upper and lower two rollers is provided with tongue and groove or concavo-convex hole, and the roll surface of another roller is provided with rubber layer; Or, the roll surface of described upper and lower two rollers is provided with tongue and groove or concavo-convex hole, and tongue and groove on the roll surface of upper and lower two rollers or concavo-convex hole engage each other when roll-in.Straight tow can be rolled into the tow with crimpness or bending degree.In guarantee with while meeting the due resistance to suction of filter stick, hardness and filter efficiency, the cellulose diacetate loading of filter stick is often propped up in effective reduction, the highest reduce 35% cellulose diacetate consumption, this is because the tow with crimpness or bending degree can not only occupy more filter stick space, structure is simple, and economic benefit is obvious.
Description
Technical field
The utility model relates to compression roller, and especially a kind of filament compression roller saving cellulose diacetate consumption, belongs to cigarette filter production technical field.
Background technology
Up to the present, on domestic and international cigarette filter stick forming machine, opening system comprises leading into silk wheel, tow opening pair roller group, tow plasticising processor, tow and stablizes smooth and easy conveying rolls, filter stick formation rifle.The tow rolled up by tow by this system first delivers to one-level, secondary tow opening pair roller through leading into a pair roller after extracting out, after shredding is carried out to tow, in wire feed bundle plasticising processor, plasticising process is carried out to the tow after shredding, smooth and easy conveying rolls is stablized afterwards by tow, send into filter stick formation rifle swimmingly by stable for the tow after plasticising process, complete filter stick formation.It can thus be appreciated that gained filter stick is by the cylindric barred body formed without several straight tow, the consumption of its tow is big is self-evident.
As everyone knows; China is tobacco big country; also be the consumption big country of diacetate fiber; diacetate fiber (i.e. CA fiber) raw material secondary cellulose acetate sheets domestic at present mainly relies on import; produce secondary cellulose acetate sheets raw material---wood material warms along with global climate; and international community's showing great attention to ecological environmental protection, cause Cellulose acetate silk seriously in short supply, force tobacco enterprise must reduce the consumption of cellulose diacetate as far as possible.Partial Tobacco enterprise of China attempts to substitute diacetate fiber with PP fiber, but the filter stick prepared because of PP fiber is poor to the adsorption capacity of aldehyde material in the low boiling component in flue gas and flue gas, cause cigarette prepared therefrom can produce heavier acid when aspirating, directly impact suction mouthfeel.Research according to the United States consumes product committee confirms, be that the filter stick cigarette that raw material is made has impact to health with PP fiber, PP fiber is safe at a normal temperature, but at igniting cigarette and when aspirating, inevitably or suction can be burned to filter stick immodestly, such PP fiber at high temperature can be cracked into propylene, then becomes carcinogen through oxidation.Scientist utilizes mouse to do experiment, and found that after sucking propylene, produces propylene oxide cause tumor growth through the effect of body intracellular metabolic, and therefore, tobacco leaf production enterprise uses PP fibrous filter candle to be very prudent.
Summary of the invention
The purpose of this utility model is: provide a kind of cellulose diacetate being squeezed into have crimpness or bending degree tow, to reduce the compression roller of the loading of this fibre bundle in cigarette filter rod.
The utility model is completed by following technical proposal: a kind of filament compression roller reducing filament consumption, comprise top roll and lower roll, the roll surface that it is characterized in that one of them roller in described upper and lower two rollers is provided with tongue and groove or concavo-convex hole, and the roll surface of another roller is provided with rubber layer;
Or, the roll surface of described upper and lower two rollers is provided with tongue and groove or concavo-convex hole, and tongue and groove on the roll surface of upper and lower two rollers or concavo-convex hole engage each other when roll-in.Bi Zhi tow to be rolled into the tow with crimpness or bending degree.
The rubber layer thickness that described roll surface is arranged is 2-6mm, and material is polyurethane rubber or ethene-acrylic rubber, straight tow to be rolled into the tow with crimpness or bending degree.
Tongue and groove on described roll surface is axially set to strip tongue and groove along roll surface, and the section configuration of strip tongue and groove is rectangle, V-arrangement, semicircle.
The degree of depth of described tongue and groove is 0.25-0.90mm, and width is 0. 25-0.8mm, and inter-alveolar distance is 0.1-0.2mm.
Concavo-convex hole on described roll surface is arranged along roll surface interval, and the section configuration in concavo-convex hole is rectangle, V-arrangement, semicircle.
The degree of depth in described concavo-convex hole is 0.25-0.90mm, and width is 0. 25-0.8mm, and hole spacing is 0.1-0.2mm.
The utility model has following advantages and effect: adopt such scheme, by tongue and groove that upper and lower pair roller roll surface is arranged or concavo-convex hole, straight fibre bundle is rolled into the tow with crimpness or bending degree.In guarantee with while meeting the due resistance to suction of filter stick, hardness and filter efficiency, the cellulose diacetate loading of filter stick is often propped up in effective reduction, the highest reduce 35% cellulose diacetate consumption, this is because the tow with crimpness or bending degree can not only occupy more filter stick space, both ensured and met filter rod quality characteristic, can save and reduce again two acetic acid (CA) filament consumption, structure is simple, and economic benefit is obvious.
