Fig. 2 is the profile of anti-set-off air dancing roll；
Fig. 3 is the enlarged drawing of Fig. 2.
Specific embodiment
Specific embodiment of the invention is illustrated below in conjunction with accompanying drawing.
As illustrated in fig. 1 and 2, the present invention provides a kind of anti-set-off air dancing roll, including support 100, roll body 200, air inlet
Pipe 300, axle sleeve 400 and sealing ring 500.
The two ends of roll body 200 are rotated with support 100 by bearing 110 and are connected on support 100, and roll body 200 is used for branch
The stocks such as dynamic paper, film are shifted, can be rotated with the movement of stock.Wherein, support 100 refers to the shell of printing equipment
Body or wall etc. only show the part being connected with roll body 200 for supporting, installing the part of dancing roll, in figure.
Roll body 200 is hollow, and one end has an air inlet 210, other end closing, the cavity phase in air inlet 210 and roll body 200
It is logical.
The steam vent 220 that the circumferential wall of roll body 200 is uniformly arranged with several, specifically：220 points of several steam vents
It is 6-12 groups, every group includes 8-12 steam vent 220, around roll body 200 1 weeks, annular array, along the length of roll body 200 between each group
Degree direction is uniformly arranged.
Wherein, as shown in figure 3, the internal diameter of steam vent 220 increases along the direction that gas is discharged, be conducive to increase gas and hold
The contact area of thing is printed, stock is smoothly passed.
One end of air inlet pipe 300 passes through air inlet 210, stretches into roll body 200, and the inwall with the other end of roll body 200 is rotated
Connection.The remainder (non-display portion in figure) of air inlet pipe 300 is fixed, and is not rotated with roll body 200, i.e., roll body 200 can phase
Rotated for air inlet pipe 300, air inlet pipe 300 can be fixed on other positions of support, or be fixed on the fixed support such as wall
On part.
The gas port 310 that the tube wall of air inlet pipe 300 is uniformly arranged with several, specifically：310 points of several gas ports
It is 6-12 groups, every group includes 4-8 gas port 310, around air inlet pipe 300 1 weeks, annular array, along air inlet pipe 300 between each group
Length direction be uniformly arranged.
Wherein, as shown in figure 3, gas port 310 is staggered with steam vent 220, the gas for discharging gas port 310 will not
Directly discharged from steam vent 220, so that the gas in roll body 200 is more evenly distributed.
Wherein, total opening section product of whole gas ports 310, the total opening section more than whole steam vents 220 is accumulated, i.e., entirely
The amount that portion's gas port 310 can be vented body is more than the amount that whole steam vents 220 can be vented body, so that steam vent 220 has gas all the time
Body is discharged.
In the present embodiment, the quantity and arrangement mode of steam vent 220 and gas port 310 can be according to roll body 200 and air inlet pipe
300 specification and change.
Axle sleeve 400 is enclosed within the air inlet pipe 300 outside one end with air inlet 210 of roll body 200 and the end.Axle sleeve 400
The opening sleeve of one end is rotated by bearing 410 with one end of roll body 200 and is connected on one end of roll body 200.Axle sleeve 400 is another
The opening at end is regularly enclosed within the air inlet pipe 300 outside roll body 200, and is provided with sealing ring between the opening and air inlet pipe 300
500.Axle sleeve 400 and sealing ring 500 are fixed with air inlet pipe 300, are not rotated with roll body, the air inlet for sealing roll body 200
210。
As shown in Fig. 2 when using, gas is input into air inlet pipe 300, the gas in air inlet pipe 300 is entered by gas port 310
In roll body 200, and it is evenly distributed in roll body 200, the gas in roll body 200 is sprayed by steam vent 220 again, makes stock and roller
The surface of body 200 separates, so as to avoid ink or glue on stock by set-off.Gas flow direction is as shown by arrows in FIG..
In the present embodiment, roll body 200 can also two ends be respectively provided with air inlet, air inlet pipe passes through roll body, from two ends air inlet.
