The specific embodiment
See Fig. 1, the structural representation of shown flat card, revolving flats unit 2 is arranged on the top of cylinder 1, and forms a cover plate combing zone with cylinder 1.In addition, also be provided with front combing district, rear combing district and combing district, bottom around cylinder 1, need the fiber 9 of combing to supply with from the cotton feeding box (not shown), receive and be transmitted to cylinder 1 by licker-in 3, fiber on cylinder 1 by combing and cleaning, whole process is undertaken by cylinder 1 and the steady job element and revolving flats unit 2 actings in conjunction that are arranged on different combings districts, and this revolving flats unit 2 is along the part revolution operation of cylinder 1.
The fiber web that forms on cylinder 1 is received by doffer 4 and form fiber skein 10 in efferent section subsequently, and then this fiber skein 10 is left in the bar cylinder in some way by strip holding structure (not shown).
In the process of combing, when the cover plate of cover plate unit 2 was rotating in the end, a lot of impurity on cover plate can fall down, and the impurity that drops is collected and enters setting front blowpipe 5 thereunder.
improvement along with flat card, the cover plate of cover plate unit 2 all increases on quantity and width to some extent, for example the model of Rieter (RIETER) company is the flat card of C70, the active length of its combing has increased to 1.5 meters, and the quantity of revolving flats also increases to some extent, be that more cover plate covers on cylinder formation larger effective cover plate combing district, this just means that more impurity can be by combing out and adhere on the cover board, when having more impurity when running to the end revolution, cover plate falls down, these impurity are collected subsequently to enter thereunder front blowpipe 5 are set, one end of front blowpipe 5 is provided with the jet-impingement device, the jet-impingement device is connected (not shown) with air supply system, the other end is connected with the air draft system (not shown) usually.Jet-impingement device jet-stream wind in the pipeline, for example usually along the axial direction of pipeline, the impurity that drops is removed, along with the impurity that drops increases, dependence is arranged on a jet-impingement device of an end of front blowpipe can not in time remove the impurity that drops, and easily causes line clogging.
Fig. 2, Fig. 3 show a kind of structural representation of front blowpipe 5 of the present utility model, are provided with on the active length of front blowpipe 5 for the opening 11 of collecting impurity, and front blowpipe 5 one ends are provided with a jet-impingement device 6.On the active length of described pipeline, increase arranges at least one jet-impingement device, and having illustrated in Fig. 2 increases by two jet- impingement devices 7,8 that arrange, and jet- impingement device 6,7 all is connected (not shown) with air supply system with being connected.Described jet- impingement device 6,7 and 8 are arranged on position (the duct bottom here of adjacent conduit bottom, it is lowest part in pipeline, see Fig. 3), and eject air-flow facing to duct bottom, described air-flow in pipeline in the shape of a spiral along pipe lengths flow (direction shown in arrow and track in Fig. 2), the jet-impingement device that increases can be strengthened the air-flow in pipeline, thereby form stronger spiral air flow in whole pipeline, the movement of accelerating impurity more effectively, impurity in pipeline is removed, prevent that front blowpipe from blocking.
wherein, as shown in Figure 3, front blowpipe 5 is provided with opening 11, in order to guide better the impurity that drops to enter pipeline from opening 11, direction along spiral air flow, next end at opening 11 is provided with a upstanding portion 12, this upstanding portion can be also the extension of duct wall, opening 11 must have certain width so that the assorted bits of large grain and/or fiber can be by drop inlet pipe roads of opening, can not blow to outside pipeline in order to ensure spiral air flow through opening 11 time simultaneously, opening 11 must make spiral air flow can not strike upstanding portion 12 simultaneously, spiral air flow only flows at pipe interior, more being conducive to impurity enters in pipeline, and impurity is remained in pipeline, make removing more effective.
Described jet-impingement device can be set to the continuous injection air-flow as required, perhaps time interval ground jet-stream wind.
Fig. 4, Fig. 5 discloses another kind of front blowpipe 5 ', its structure is substantially similar, difference exists: it is not to have level and smooth circular arc tube wall as common pipeline, but by the sheet metal continuous bending is formed a passage, this passage has in the longitudinal direction equally for the opening 11 ' of collecting impurity, opening 11 ' is provided with upstanding portion 12 ', pipeline one end is provided with a jet-impingement device 6 ', can a jet-impingement device 7 ' be set according to described scheme increase on active length in pipeline, also can increase simultaneously two jet-impingement devices 7 ' and 8 ' (Fig. 4), perhaps increase more injection apparatus is set, be used for strengthening forming spiral air flow in pipeline, removal of contamination.
Fig. 6 shows another kind of front blowpipe 5 ' ', an end at pipeline is provided with jet-impingement device 6 ' ', increase on its length direction and be provided with at least one jet-impingement device, there is shown two jet-impingement devices 7 ' of increase ' and 8 ' ', shown jet-impingement device 6 ' ', 7 ' ' and 8 ' ' all be arranged on the bottom of pipeline, and along front blowpipe 5 ' ' the axial direction jet-stream wind, owing to having increased one or more jet-impingement devices, air-flow in pipeline strengthens greatly, can more effectively the impurity in pipeline be removed, prevent that front blowpipe from stopping up.
A plurality of jet-impingement devices that increase can according to circumstances be distributed in the diverse location of the whole active length of pipeline, for example substantially be evenly distributed on the whole active length of front blowpipe, can be also other distribution modes, for example all jet-impingement devices can be concentrated on the end, perhaps part jet-impingement device is arranged on the end, other active length that is distributed in pipeline is first-class, no longer is described in detail at this.After having increased the jet-impingement device, the air-flow in pipeline strengthens, and its removal of impurities ability just will strengthen greatly, and removal of impurities will be more effective, can prevent effectively that front blowpipe from blocking.
The utility model also relates to a kind of flat card, and it has above-mentioned front blowpipe 5,5 ' or 5 ' '.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
