Abstract
The utility model discloses a variable cross-section air channel for a cotton fine combing machine. The variable cross-section air channel for the cotton fine combing machine comprises an air channel body, wherein one end of the air channel body is closed, the other end of the air channel body is connected with a fan, and the cross section of the air channel body is of a rectangular structure. A plurality of cotton discharging openings are evenly formed in the upper wall face of the air channel body along the length direction of the air channel body. A plurality of sight holes are formed in one side wall face of the air channel body. An insertion plate used for regulating air quantity is arranged inside the end, connected with the fan, of the air channel body. The variable cross-section air channel for the cotton fine combing machine is characterized in that the cross section of the air channel body is arranged to be gradually reduced from the end connected with the fan to the closed end.
Description
Technical field
The utility model relates to field of textile machinery, relates to a kind of cotton comber specifically and uses the variable cross-section air channel.
Background technology
As everyone knows, the high-quality cotton adopts combing spinning system, it is closely related that quality quality and the cotton noils of combing sliver got rid of quality, the noil of combing machine is got rid of at present, mainly be to utilize blower fan to produce the air draught air-flow, the air draught air-flow carries out noil by the air channel to the noil mouth of combing machine and gets rid of, present air channel each sectional dimension along its length is identical, end air-flow suction near blower fan is bigger like this, and it is less away from the other end air-flow suction in the air channel of blower fan, noil is got rid of frequent the appearance and is got rid of thoroughly near blower fan one end noil, but away from blower fan one end noil eliminating phenomenon not to the utmost.Because not thorough away from the eliminating of blower fan one end noil, the cylinder carding power of this end descends, the quality that generates sliver descends, and has finally influenced the quality of yarn, and the quality of yarn descends, and finally the quality of resultant yarn also descends.
Summary of the invention
The purpose of this utility model provides a kind of cotton comber to use the variable cross-section air channel at above-mentioned existing in prior technology weak point just.The air channel of this utility model adopts the cross section to be arranged by big gradually little mode to the end away from blower fan from an end that is connected with blower fan, thereby it is inconsistent to improve combing machine noil mouth linters rate, and the yarn quality descends, the problem that final combed yarn quality descends.
The purpose of this utility model can realize by following technical proposals:
It comprises end sealing to the utility model cotton comber with the variable cross-section air channel, the other end links to each other with blower fan and the air channel body of the rectangular structure in cross section, the upper wall surface of described air channel body evenly offers several noil mouths along the air channel length direction, and a side wall surface at described air channel body offers several windows, be provided with for the plate of regulating air quantity in link to each other with the blower fan inside of end of air channel body, the cross section of described air channel body is held from linking to each other with blower fan to be by gradually little mode greatly to blind end and is arranged.
Know-why of the present utility model is as follows:
The utility model is according to fluid mechanics principle, when fluid is flowed through the constant straight tube of section, owing to the frictional force effect produces along the stroke pressure loss, than crushing computing formula:
R
m=γ/（2?ab/?a+b）（ρv
2/2）
R
m--the fricting resistance loss of-unit length pipeline, be called for short than crushing (or specific frictional resistance) (Pa/m);
γ------fricting resistance loss coefficient;
The length of a------rectangular duct (m);
Wide (m) of b------rectangular duct;
ρ--density (the kg/m of----pipeline inner fluid
3);
The average speed (m/s) of v------pipeline inner fluid
Frictional resistance makes the pressure of the interior air-flow of pipeline reduce gradually just, and row's noil ability reduces gradually.Constant in order to keep air-flow row noil ability, increase with air channel length, duct cross-section is more far away apart from blower fan, and the sectional dimension in air channel is more little, and it is identical to reach row's noil ability.
The beneficial effects of the utility model are as follows:
It is not of uniform size that the utility model can well improve existing combing machine noil eliminating air channel air draught ability, the noil elimination factor is inconsistent, cause the quality of yarn to descend, the problem that the quality of final resultant yarn also descends, make the noil mouth draw the ability unanimity of noil, thereby make the carding power raising away from the cylinder of blower fan one end, make the quality of the combed yarn that combing goes out be improved.
Description of drawings
Fig. 1 is air channel structure signal of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Among the figure: the 1st, the air channel body; The 2nd, side plate; The 3rd, plate.
The specific embodiment
The utility model is described further below with reference to embodiment (accompanying drawing):
Shown in Fig. 1-2, it comprises end sealing to the utility model cotton comber with the variable cross-section air channel, the other end links to each other with blower fan, and the air channel body 1 of the rectangular structure in cross section, the upper wall surface of described air channel body evenly offers eight noil mouths along the air channel length direction, and a side wall surface at described air channel body offers four windows, be provided with for the plate 3 of regulating air quantity in link to each other with the blower fan inside of end of air channel body, plate 3 inserts one side from the air channel, be inlaid in the guide-track groove that is arranged at inner top and bottom, air channel, the cross section of described air channel body is held from linking to each other with blower fan to be by big gradually little mode to blind end and is arranged, as shown in Figure 2, size A is greater than size B.
As shown in Figure 3, air channel of the present utility model body is to be U-shaped structure by a side plate 2 and a cross section to be connected by connector.
When cotton comber is worked, when the noil mouth is far away apart from blower fan, one side size of the square-section of air-suction duct reduces gradually, the duct cross-section area reduces gradually, the air draught ability size that guarantees cylinder below noil mouth is consistent, it is identical to inhale the noil ability, and the noil of noil mouth can both be excluded totally like this, and the quality that finally generates the combing sliver is better.
