The negative pressure that inlet scoop is produced is big, and the negative pressure produced away from the inlet scoop at blower negative pressure airduct is small, is so to make air draught negative pressure small
Inlet scoop can also have enough negative-pressure air-suctions, the power of induced-draught electric motor must be increased, air-suction duct is so not only resulted in
System effectiveness is reduced, and power loss is big；And the big position of aspiration channel negative pressure produces larger air draught power, can make work top
The rove of spinning produces tension fluctuation by a relatively large margin, and tension force shakiness will cause yarn quality not ensure；Another aspect negative pressure
Small one end, table top flyings cleaning is not clean, and rove is easily incidentally entered in cotton spinning, produces spot, influences spinning quality.It is existing
There is the aspiration channel of technology, the air draught vacuum magnitude of inlet scoop position can not be monitored, and easily cause air draught negative pressure excessive or too small
Situation, influences the quality of production of cotton spinning roving machine.
Therefore, it is necessary to a kind of new cotton spinning roving machine be proposed, to overcome the defect of traditional cotton spinning roving machine.

As a kind of perferred technical scheme, the inlet scoop is multiple, and the hollow aspiration channel correspondence is the multiple to inhale
Air port sets multiple wind pressure sensors.
As the optimal technical scheme to above scheme, one end of the hollow aspiration channel is provided with connecting plate, it is described in
The other end of suction airduct is provided with plug or connecting plate.
As technical scheme still more preferably, the cross sectional shape of the connecting plate and the hollow air draught tube section
Shape is consistent；The internal diameter of the external diameter in the connecting plate section and the hollow air draught tube section matches.
As technical scheme still further preferably, described two or multiple hollow aspiration channels are connected by the connecting plate
It is structure as a whole.
A kind of cotton spinning roving machine disclosed in the utility model, air suction duct of roving frame correspondence inlet scoop position is provided with blast biography
Sensor, wind pressure sensor can monitor the air draught power at inlet scoop in real time, and feed back, it is to avoid the air draught power at inlet scoop it is excessive or
It is too small that the cotton spinning roving machine quality of production is impacted, improve the spinning quality of cotton spinning roving machine.
It is effectively equal using a long air-suction duct is formed after multiple hollow aspiration channel connections as a kind of preferred scheme
Weighed negative pressure air stream in aspiration channel, makes air draught blast balanced, stably, while improving air draught efficiency, further lifts this practicality
A kind of quality of production of new cotton spinning roving machine.
Brief description of the drawings
