Abstract
A variable cross-section duct for a cotton comber comprises a duct body. One end of the duct body is closed, the other end of the duct body is connected with a fan, and cross section of the duct body is rectangular. The upper wall of the duct body is evenly provided with a plurality of noil outlets along the duct lengthwise, one side wall of the duct body is provided with a plurality of eye holes, and an insert plate for adjusting air quantity is arranged on the inside of an end, connected with the fan, of the duct body. The variable cross-section duct for the cotton comber is characterized in that the cross section of the duct body is arranged from the end connected with the fan to the closed end from large to small.
Description
Technical field
The present invention relates to field of textile machinery, relate to specifically a kind of cotton comber and use the variable cross-section air channel.
Background technology
As everyone knows, the high-quality cotton adopts combing spinning system, it is closely related that the quality of combing sliver and cotton noils are 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 larger like this, and less away from the other end air-flow suction in the air channel of blower fan, noil is got rid of and is often occurred getting rid of thoroughly near blower fan one end noil, but arranges aliquant phenomenon away from blower fan one end noil.Because not thorough away from the eliminating of blower fan one end noil, the Cylinder Carding ability of this end descends, and generates the Quality Down of sliver, has finally affected the quality of yarn, the Quality Down of yarn, the quality of final resultant yarn also descends.
Summary of the invention
Purpose of the present invention provides a kind of cotton comber to use the variable cross-section air channel for the existing weak point of above-mentioned prior art just.The air channel of this utility model adopts the cross section to be arranged by large 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, yarn Quality Down, the problem that final combed yarn quality descends.
Purpose of the present invention can realize by following technical proposals:
It comprises end sealing to cotton comber of the present invention 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 large gradually little mode to blind end and is arranged.
Know-why of the present invention is as follows:
The present invention is according to fluid mechanics principle, and flow is when 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;
Density (the kg/m of ρ------pipeline inner fluid
3);
The average speed (m/s) of v------pipeline inner fluid
Frictional resistance is so that the pressure of the interior air-flow of pipeline reduces 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 far away apart from blower fan, and the sectional dimension in air channel is less, reaches row's noil ability identical.
Beneficial effect of the present invention is as follows:
The present invention can well improve existing combing machine noil eliminating air channel air draught capacity of water and differ, the noil elimination factor is inconsistent, the Quality Down that causes yarn, the problem that the quality of final resultant yarn also descends, make the ability of noil mouth absorption noil consistent, thereby make the carding power raising away from the cylinder of blower fan one end, so that the quality of the combed yarn that combing goes out is improved.
Description of drawings
Fig. 1 is air channel structure signal of the present invention.
Fig. 2 is the top 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 present invention is described further below with reference to embodiment (accompanying drawing):
Shown in Fig. 1-2, it comprises end sealing to cotton comber of the present invention 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 large 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 invention 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 capacity of water that guarantees cylinder below noil mouth is consistent, inhale the noil ability identical, the noil of noil mouth can both be excluded totally like this, and the quality that finally generates the combing sliver is better.
Claims (1)
1. a cotton comber is used the variable cross-section air channel, it comprises end sealing, 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, it is characterized in that: the cross section of described air channel body is held from linking to each other with blower fan to be by large gradually little mode to blind end and is arranged.
