In order to solve the above technical problems, the technical solution that the utility model uses is: providing a kind of based on negative pressure suction
Attached mesh type doffer, comprising: the first connecting flange, the second connecting flange, doffer's cylinder and vacuum pump, first connection method
The setting of blue and the second connecting flange has been arranged concentrically and doffer's inner barrel in doffer's cylinder both ends, first connecting flange
The hollow pipe of connection, outwardly extending drive shaft has been arranged concentrically in second connecting flange, and doffer's cylinder includes straight
Cylinder and the plugging plate at straight tube both ends is set, absorption micropore is densely covered in the straight tube and forms mesh, the hollow pipe end
It is provided with rotary air connector, is provided with tracheae between the rotary air connector and the air inlet of vacuum pump.
In one preferred embodiment of the utility model, the hollow pipe is connect with the first connecting flange welded seal.
In one preferred embodiment of the utility model, spiral shell is respectively adopted in first connecting flange and the second connecting flange
Bolt is connected with corresponding plugging plate, and the closure plate surface is provided with seal washer.
In one preferred embodiment of the utility model, the straight tube is welded and fixed with plugging plate.
In one preferred embodiment of the utility model, the straight tube is aluminium alloy cylinder.
In one preferred embodiment of the utility model, keyway is provided in the drive shaft.
In one preferred embodiment of the utility model, the diameter of the absorption micropore is 0.5 ~ 1mm.
The beneficial effects of the utility model are: a kind of mesh type doffer based on negative-pressure adsorption that the utility model is pointed out,
Doffer's cylinder with absorption micropore is especially used, the use of needle cloth is avoided, reduces self weight and driving energy consumption, Er Qiezhen
Sky pump can vacuumize doffer's cylinder, suction be formed in absorption micropore surface using internal negative pressure environment, to cylinder surface fibre
Dimension carries out absorption migration, and changes fibre migration adsorption effect by the power of vacuum pump, adjusts convenience, and practicability is good, in addition,
Part spun yarn impurity and short flannel can be excluded from absorption micropore, reduce strip percentage of impurity and short fiber content.
Detailed description of the invention
