In the vacuum absorption device of the printing machine, the blower is vertically disposed at the center of vacuum tank bottom,
Impeller protrudes into vacuum tank, and air inlet is offered right above impeller, and there are two the interior circumferential settings along air inlet of vacuum tank etc.
The exhaust outlet for dividing ground to surround the air inlet, each exhaust outlet respectively pass through an exhausting duct and connect corresponding connecting tube.
In the vacuum absorption device of the printing machine, the exhaust outlet is scroll casing shape, two exhaust outlet central symmetries point
Cloth.
In the vacuum absorption device of the printing machine, the exhausting duct is logical along the tangentially extending straight line of exhaust outlet
Road.
In the vacuum absorption device of the printing machine, the air exhaust slot is rectangular-shape, is opened up on the side wall at both ends
There is rectangle connector similar with the sidewall shape, the outlet of the connecting tube and the connector are adapted, the outlet of connecting tube
It is connect with the connector.
In the vacuum absorption device of the printing machine, the opening of the air exhaust slot is provided with homogenating plate.
The utility model has the advantages that
The present invention provides a kind of vacuum absorption devices of printing machine, air exhaust slot are arranged in the top of transmission wheel, air exhaust slot has
Opening directed downwardly, the air that blower extracts are discharged into air exhaust slot by connecting tube, and air can flow out down from the opening of air exhaust slot, so
It is extracted by blower, is so recycled again afterwards, be supplemented in come without the air around printing machine, to avoid air-flow in surrounding air
A large amount of dust bring into printing machine, and then guarantee printing quality.
Detailed description of the invention
Fig. 1 is the perspective view of the vacuum absorption device of printing machine provided by the invention.
Fig. 2 is the front view of the vacuum absorption device of printing machine provided by the invention.
Fig. 3 is the Section A-A figure in Fig. 2.
Specific embodiment
The present invention provides a kind of vacuum absorption device of printing machine, to make the purpose of the present invention, technical solution and effect more
Add clear, clear, the present invention is described in more detail as follows in conjunction with drawings and embodiments.It should be appreciated that described herein
Specific examples are only used to explain the present invention, is not intended to limit the present invention.
Please refer to Fig. 1-3, a kind of vacuum absorption device of printing machine provided by the invention, the biography including printing machine is arranged in
Vacuum tank 1 below defeated wheel (not having picture in figure), is arranged blower 2 on the vacuum box, and the air exhaust slot 3 above transmission wheel is arranged in,
And connect the exhaust outlet of blower and the connecting tube 4 of air exhaust slot；The air exhaust slot 3 is provided with opening 3.1 directed downwardly, the blower
It is evacuated from vacuum tank and passes through connecting tube and expel air into air exhaust slot.
When work, blower takes the air in vacuum tank away, generates negative pressure and transmits to which cardboard to be adsorbed in transmission wheel, and
The air of extraction can be discharged into air exhaust slot by connecting tube, then be flowed downward out from the opening of air exhaust slot, then be taken out again by blower
It takes, so recycles, be supplemented in come without the air around printing machine, to avoid air-flow a large amount of dust band in surrounding air
Enter in printing machine, and then guarantees printing quality.As it can be seen that the vacuum absorption device can be such that air circulates in printing machine,
The dust for reducing ambient enviroment enters printing machine.
Further, the connecting tube 4 is provided with two, which is separately connected the both ends of air exhaust slot 3, blower
2 can be discharged the air of extraction from two connecting tubes etc. point.If connecting tube, the sky of reflux only is arranged in one end of air exhaust slot
Gas can all flow into air exhaust slot from this, then suck vacuum tank, uneven so as to cause the air-flow above cardboard, be unfavorable for cardboard
Steady transmission；This is in air exhaust slot both ends setting connecting tube, and flows out the air of reflux partially from air exhaust slot both ends, can
The uniformity for greatly improving air-flow, is conducive to the steady transmission of cardboard, and with only one connecting tube the case where compared with, stream
The total cross-sectional area in dynamic channel is bigger, and the flow velocity of air will be greatly reduced, smaller to the interference wind of cardboard, further increases paper
The stability of plate transmission.
Specifically, the blower 2 is vertically disposed at the center of 1 bottom of vacuum tank, impeller is protruded into vacuum tank, impeller
Surface offer air inlet 2.1, there are two partially surrounds the air inlet to the circumferential setting in vacuum tank along air inlet
Exhaust outlet 2.2, each exhaust outlet respectively pass through an exhausting duct 2.3 and connect corresponding connecting tube 4.When the wheel rotation of blower, meeting
The air of surrounding is partially pushed into exhaust outlet 2.2, this partial air can be flow at connecting tube 4 by exhausting duct 2.3, and true
The air of empty van can be supplemented in around impeller from air inlet 2.1, to realize vacuum suction and air-flow equal part.
Preferably, the exhaust outlet 2.2 is scroll casing shape, two exhaust outlet central symmetry distributions.Since exhaust outlet is spiral case
Shape, inner flow passage gradually broaden along helix, the dynamic pressure of air-flow can be converted to static pressure, can reduce resistance and noise,
To reduce power consumption and improve operating environment.
In the present embodiment, the exhausting duct 2.3 is the tangentially extending beeline channel along exhaust outlet 2.2, can further be dropped
Lower resistance and noise.
Specifically, the air exhaust slot 3 is rectangular-shape, (this similar to the sidewall shape is offered on the side wall at both ends
Place it is similar refer to it is similar in mathematical meaning) rectangle connector 3.2, the outlet of the connecting tube 4 and 3.2 phase of connector
It adapts to, the outlet of connecting tube is connect with the connector.The structure can make air-flow enter air exhaust slot with air curtain shape, make air equably
It is flowed out from opening 3.1 again after scattering, can further improve the uniformity of air-flow, reduce the influence for transporting stationarity to cardboard.
In order to further improve the uniformity of air-flow, homogenating plate can be set at the opening 3.1 of the air exhaust slot.?
Aerofoil is one block of plate for being evenly distributed exhaust vent, the air of air exhaust slot can equably be flowed out from each exhaust vent.
It, can according to the technique and scheme of the present invention and its hair it is understood that for those of ordinary skills
Bright design is subject to equivalent substitution or change, and all these changes or replacement all should belong to protection scope of the present invention.
