Description

A kind of wood pulp filter material mouth rod passive transport becomes strip device

Technical field:

The utility model belongs to technical field of tobacco, is a kind of cigarette filter rod production equipment, and particularly a kind of wood pulp filter material mouth rod passive transport becomes strip device.

Background technology:

The reducing tar and reducing harm of cigarette is that tobacco business outstanding scientific research emphasis in the whole world also is an industry difficult problem.Design is one of technology of generally adopting of reducing tar and reducing harm with selecting different filter tips for use.At present, except being extensive use of lengthening filter tip active carbon filter, double filter has also been proposed, triple filter tips, designs such as cavity filters both at home and abroad.Patent 95120341x is proposed to be wound in bar-shaped and the preparation filter tip with mesh structure and the sheet filtering material that comprises cellulose ester short fiber by Japanese a company, propose to utilize the idea of short fiber material earlier as filter material, and proved the filter tip good filtration effect of making than acetic acid and the third fine long fibre, lose little than crimped paper filter tip fragrance and palatability that wood pulp is made.Japan a company has produced at present and has added adhesive by wood pulp make the filter tip that nonwoven twines behind compressing tablet, and has proved the tar-reducing harm-reducing effect of pulpwood uniqueness as filter material the time.Patent 90104165 by American's application has also proposed to add the native cellulose fibre (comprising wood pulp cellulose) of effective dose in nonwoven fibrous web, to increase filter effect.Therefore adopting short fiber (and then adopt natural plant fibre, again and then adopt wood pulp cellulose) to substitute acetate fiber can increase filter effect and extensively approved.But all there is the difficult problem that can't go beyond at present in the technology that went up: short fiber is wood pulp cellulose tensile property extreme difference particularly, can't use existing mouth rod forming machine, and just part is added some wood pulp celluloses.So just have some problems: 1, filter material and flue gas contact area reduce poor filtration effect greatly; 2, the stroke of flue gas in filter tip is short, poor filtration effect; That 3, comes out reduces the significantly special hydroxyl quantity of suction-operated, poor to tar and harmful substance people adsorption effect; 4, can not be directly formed to mouth rod complex process, cost increases; 5, can not use wood pulp cellulose fully in the filter material.May cause resistance to suction to increase, the adsorption filtration effect reduces.

Summary of the invention:

On the basis that above background technology is analyzed.We propose can with short fiber (and then be natural plant fibre, again and then be wood pulp cellulose, again so be the wood pulp short floss fibre) be directly formed to filter stick.The inventor proposes a whole set of former, comprises wood pulp fiter tip filtering material reducing mechanism, and negative-pressure adsorption becomes twist device, and passive transport becomes strip device, to realize and the docking of existing mouth rod forming machine.The purpose of this utility model provides a kind ofly the continuous wood pulp cellulose undercoat suede that has become to twist with the fingers that wood pulp filter material mouth rod negative-pressure adsorption becomes twist device to provide is provided is twisted with the fingers, and with its bundle is molded be and the identical bar shaped of the excellent thickness of standard mouth.Wrap up the donor cluster of shaping paper for up to standard being used for of existing mouth rod forming machine supply.

Realize that the technical solution of the utility model is that a kind of wood pulp filter material mouth rod passive transport becomes strip device, has frame, the tool characteristics are: frame is provided with integer rifle and moulding rifle, the integer rifle is fixed on the integer platform, the integer rifle is made up of base plate and cover plate, offer half slot respectively above the base plate and below the cover plate, two half slots are formed gun barrel, and the charging aperture of gun barrel is bell mouth shape; Be provided with the wraparound conveyer belt in the gun barrel, conveyer belt twines reforming station, gun barrel, driving wheel and distend wheel and rotates; The back journey of shaping rifle is the moulding rifle, and the moulding rifle is fixed on the workbench, and the moulding rifle has base plate, cover plate, gun barrel, charging aperture, conveyer belt, driving wheel and the distend wheel with integer rifle same configuration; The bore of discharging opening is consistent with the excellent core bore of standard mouth at least in the moulding rifle.

Because the utility model was taked technical scheme, realized the wood pulp cellulose wraparound that will become to twist with the fingers, be squeezed into tow strip up to standard, and passive transport is to the mouth rod forming machine of next stage, the operation of wrapping up shaping paper.This equipment is applied to filter tip production and belongs to initiative.

Description of drawings:

In order further to understand specific structural features of the present utility model, the utility model is described in further detail below in conjunction with drawings and Examples

Fig. 1 represents general assembly structural representation of the present utility model

Fig. 2 represents shaping rifle structural representation in the utility model

The specific embodiment:

As shown in Figure 1, the utlity model has frame 1, frame is provided with shaping rifle 2 and moulding rifle 3, and shaping rifle 2 is fixed on the reforming station 4.Shaping rifle 2 is made up of base plate 5 and cover plate 6 as shown in Figure 2, and base plate 5 is fixed on the reforming station 4 by pin, and cover plate 6 is fixed on the base plate 5 by adjustable paw 7.The lower surface of the upper surface of base plate 5 and cover plate 6 offers half slot 8 respectively and 9, two half slots are combined into gun barrel, and the charging aperture 10 of gun barrel is bell mouth shape, makes things convenient for suede to twist with the fingers and enters, and is unlikely to make suede to be twisted with the fingers and is detained.Be provided with wraparound conveyer belt 11 in the gun barrel, conveyer belt 11 is become basic drum by wraparound after entering gun barrel, suede is twisted with the fingers wrap up, and with its extruding slivering, drives it on the one hand and moves ahead on the one hand.Conveyer belt 11 twines reforming station 4, gun barrel, driving wheel 12 and distend wheel 13 and rotates.The back journey of shaping rifle 2 is a moulding rifle 3.Moulding rifle 3 is fixed on the workbench 14, have base plate 15, cover plate 16, gun barrel, charging aperture, conveyer belt 17, driving wheel 18 and distend wheel 19 with shaping rifle 2 same configuration, the internal diameter of different the is conveyer belt under the gun barrel winding may more approach the bore of standard filter rod core.

The passive course of conveying that suede is twisted with the fingers is: the wood pulp undercoat that becomes to twist with the fingers is twisted with the fingers the conveyer belt 11 that falls into earlier on the reforming station 4, along with conveyer belt 11 rotates the charging aperture 10 that enters bell mouth shape, conveyer belt 11 is subjected to the gun barrel restriction to be become tubular by winding, suede is twisted with the fingers and to be transported by winding in this process, falls into conveyer belt 17 on the shaping platform 14 from discharging opening.Further pushed slivering until discharging opening again, be that next step operation---the mouth rod forming machine provides the tow strip of bore up to standard, wrap up forming paper and sealing adhesive process, and then segment becomes the mouth rod by winding.
