The filter stick drying machine can completely dry the filter sticks, the fast cooling is realized, the production efficiency is effectively improved, the quality of the filter sticks is ensured, and the production cost is lowered.
Description
Technical field
The utility model relates to a kind of drying plant, a kind of being applied in the production of cigarettes of more specifically saying so, the equipment that filter stick is dried.
Background technology
Filter stick is to be raw material with filtering materials such as diacetate fiber and polypropylene tows, through roll form have a strainability clava; Filter stick is filter tip through cutting, and the filter tip tipping is played the effect of filtration in the aspiration end of Cigarette to the tar in the cigarette smoke, nicotine etc.The cigarette tipping filter tip can improve the security of smoking, alleviates smoking and healthy contradiction.The tobacco business of countries in the world requires more and more higher to the selection of cigarette filter material, both required good filtration effect, reducing tar and reducing harm effect obvious, and the suction flavor to cigarette makes moderate progress again.
Early stage filter stick raw material mainly are diacetate fibers, but its raw material is limited, complex manufacturing, investment are bigger.Some low-grade cigarette filter materials are partly replaced by polypropylene tows in recent years.Polypropylene fibre is to melt the synthetic fibers that spinning is made by polypropylene through heat, is a kind of macromolecule chain compound.Polypropylene fibre tow raw material sources are abundant, and production technology is comparatively simple, and production cost is low, and are nontoxic and filter effect is obvious, meet the basic demand of cigarette material, are the substitutes of acetate fiber preferably at present.But the polypropylene fibre mechanical strength is higher, elasticity is big, fiber is thick and stiff and do not have suitable plasticizer, has increased certain degree of difficulty for filter stick machine-shaping, has limited its application in medium-to-high grade cigarette.
For this reason, the existing correlation technique that polypropylene tows is carried out modification, the modification of being produced adds the glue filter rod and has solved the problems referred to above to a great extent, but the proposition that modification adds the glue filter rod has also proposed requirements at the higher level to the oven dry and the cooling procedure of filter stick.At present, the oven dry cooling procedure of filter stick is to utilize hot-air that it is dried after filter stick enters dryer, and then cooling naturally, but, in the actual production, often occur for the oven dry that adds the glue filter rod not thorough, make the middle part tow parcel that adds the glue filter stick incomplete, influenced the filter stick quality.Natural cooling process is slow simultaneously, has prolonged the production cycle of product, and the easy moisture absorption of filter stick is made moist in cooling procedure simultaneously, has equally also influenced the filter stick quality.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of filter stick dryer is provided, and makes the filter stick oven dry fully, and can cool off fast, in the hope of enhancing productivity, guarantee filter rod quality, falling and subtract production cost.
The utility model technical solution problem adopts following technical scheme:
The design feature of the utility model filter stick dryer is: in baking oven, be positioned at the top of filter stick conveyer chain, the direction of transfer from the arrival end of baking oven along the filter stick conveyer chain is provided with the hot air circulation at different levels air port that comprises one-level hot air circulation air port and final stage hot air circulation air port successively at interval; On the position between the port of export of described final stage hot air circulation air port and baking oven, be provided with one and force the cold wind air port.
The design feature of the utility model filter stick dryer also is:
The described hot air circulation at different levels air port in one-level hot air circulation air port and final stage hot air circulation air port that comprises forms the hot air circulation loop by circulation air path and baking oven, on the position in described hot air circulation wind at different levels air port heat exchanger is set.
In described baking oven, be positioned at the top of filter stick conveyer chain, for place, position, described hot air circulation at different levels air port, be respectively arranged with each hot air circulation blower; Corresponding to place, position, described pressure cold wind air port, be provided with and force the cold wind blower fan.
In described baking oven, be positioned at the arrival end and the port of export position of baking oven, the Seal end plate that can be used for sealing the arrival end and the port of export is set respectively.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model is provided with multiple tracks hot air circulation air port along the filter stick direction of transfer in baking oven, makes to add the glue filter rod and can dry fully, has improved the quality that adds the glue filter rod.
2, pressure cold wind circulation air port was set in the utility model before the baking oven port of export, makes filter stick in baking oven, can finish cooling simultaneously, avoided moisture absorption moisture regain in the filter stick cooling procedure, guarantee filter rod quality with this, and enhance productivity, shortened the production cycle.
3, each hot-air mouth of the utility model is set to the air port of circulating, and has effectively improved the utilization rate of hot-air, makes the existing baking oven of the thermal efficiency of baking oven improve 50%, has significantly reduced steam consumption, reduced the energy consumption, fall and subtract production cost.
4, the utility model simple in structure, reasonable in design, can carry out the processing of multiple product, its efficient height, working stability, safe and reliable.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure: 1 baking oven; The 1a arrival end; The 1b port of export; 2 Seal end plates; 3 force the cold wind air port; 4 circulation air paths; 5a one-level hot air circulation air port; 5b final stage hot air circulation air port; 6 hot air circulation blowers; 7 force the cold wind blower fan.
The specific embodiment
Referring to Fig. 1, in the present embodiment, in baking oven 1, be positioned at the top of filter stick conveyer chain, the direction of transfer from the arrival end 1a of baking oven 1 along the filter stick conveyer chain is provided with the hot air circulation at different levels air port that comprises one-level hot air circulation air port 5a and final stage hot air circulation air port 5b successively at interval; On the position between the port of export 1b of final stage hot air circulation air port 5b and baking oven 1, be provided with one and force cold wind air port 3.
In concrete the enforcement, form the hot air circulation loop by circulation air path 4 and baking oven 1, on the position in hot air circulation wind at different levels air port, heat exchanger is set in hot air circulation at different levels air port.
