Specific embodiment
The utility model provides a kind of crossbeam air channel structure of printing machine, to make the purpose of this utility model, technical solution
And effect is clearer, clear, and the utility model is further described as follows in conjunction with drawings and embodiments.It should manage
Solution, specific embodiment described herein only to explain the utility model, are not used to limit the utility model.
Herein, left and right refers to crossbeam air duct length direction, i.e. left and right directions in Fig. 2；Front and back refers to that crossbeam air duct is wide
Direction is spent, i.e. perpendicular to the direction of paper in Fig. 2.
Please refer to Fig. 1-5, a kind of crossbeam air channel structure of printing machine provided by the utility model, including horizontally disposed and cross
Section is the crossbeam air duct 1 of rectangle, is vertically arranged in crossbeam air duct top center and shaft protrudes into motor 4 in crossbeam air duct,
Centrifugal impeller 6 on machine shaft is set, and the wind-guiding shell 7 being set on centrifugal impeller；Crossbeam air duct bottom face
The position of centrifugal impeller offers air inlet 1.1, and the left or right side that crossbeam air duct top portion is located at motor is provided with air outlet 2,
Wind-guiding shell is used to the air-flow for entering crossbeam air duct all be oriented to the side of air outlet.
When work, motor driven centrifugal impeller turning handle air is sucked in crossbeam air duct, and makes to suck by wind-guiding shell
The air-flow in crossbeam air duct all passes through the side of wind-guiding shell guiding air outlet, and avoiding can not be timely after air-flow flows into the other side
It flows out and negative pressure is caused to reduce, improve adsorption capacity.
Specifically, seeing Fig. 1,4, the wind-guiding shell 7 is the wind-guiding shell of scroll casing shape, and outlet is set towards 2 side of air outlet
It sets；The wind-guiding shell covers the upper cover plate 7.2 connect in perpendicular wall upper and lower end by one piece of perpendicular wall 7.1 curved in the shape of a spiral and respectively
It is formed with lower cover plate 7.3；Upper cover plate and lower cover plate offer the circular hole 7.4 being adapted with centrifugal impeller 6, and centrifugal impeller is from upper
The circular hole of cover board protrudes into ventilation case body, and perpendicular the distance between wall 7.1 and circular hole 7.4 become larger with air current flow direction.
Centrifugal impeller rotates in ventilation case body, and the air-flow of sucking can tangentially be thrown away along the channel between centrifugal impeller and perpendicular wall
Flowing finally sprays the side for flowing to air outlet from outlet；And since the channel between centrifugal impeller and perpendicular wall gradually broadens, energy
It is enough that the dynamic pressure of air-flow is converted to static pressure, resistance and noise can be reduced, to reduce power consumption and improve operating environment.
Further, see Fig. 3, the lower section that air outlet 2 is located in the crossbeam air duct 1 is provided with deflector apron 10, this is led
It is flushed to the upper end of baffle with air outlet far from the side of motor 4, lower end is tilted towards 6 direction of centrifugal impeller.Air-flow can led
It is gradually increasing under the action of to baffle into air outlet, with comparison when being not provided with deflector apron, air-flow will not vertically hit cross
Sinuous flow is formed after the end rebound in beam air duct, air flowing is more smooth, flow is further increased, to further increase absorption
Power.
In the present embodiment, see that Fig. 3,5, the centrifugal impeller 6 include the upper plectane 6.1 and lower annulus 6.2 of coaxial arrangement, with
And the blade 6.3 between upper plectane and the edge of lower annulus is arranged in muti-piece；One is defined between upper plectane, lower annulus and blade
A air draught chamber.When centrifugal impeller rotates, blade can be tangentially discharged the air in air draught chamber, to be formed in air draught chamber negative
It presses, the air in environment can suck the air of air draught chamber supplement discharge from lower annulus.
Preferably, the lower section of the centrifugal impeller 6 is provided with a horn-like inlet scoop 8, and the inlet scoop is up-small and down-big
And air draught chamber is protruded into from lower annulus 6.2 in the upper end.Negative pressure can be improved in the inlet scoop, increases adsorption capacity, and can prevent air
It sucks air draught chamber after being discharged by blade 6.3 from lower annulus again, improves air draught efficiency.
Further, the lower end of the inlet scoop 8 is connected in a mounting ring 9, the bottom of the mounting ring and crossbeam air duct 1
Portion is tightly connected, and mounting ring surrounds entire air inlet, can avoid the air of sucking between inlet scoop and crossbeam air duct bottom
Gap flow into, further increase air draught efficiency.
Specifically, seeing Fig. 1,3, the top in the crossbeam air duct 1 is provided with motor installing hole, and motor 4 is fixed on one block of electricity
On machine mounting plate 5, which connects the cooperation of the rim seal in motor installing hole and with motor installing hole.Assembly
When, inlet scoop 8 and mounting ring 9 can be installed from motor installing hole, then motor is fixed on motor mounting plate, centrifugation
Impeller 6 is installed in shaft, wind-guiding shell 7 is fixed on motor mounting plate bottom, finally motor mounting plate together with motor, from
Lobus cardiacus wheel, wind-guiding shell are packed into motor installing hole together, are convenient to mount and dismount.
In addition, the air outlet 2 is a square tube being arranged at the top of crossbeam air duct, the upper end of the square tube is connected with one
