It is flowed out outside outer roller.There are the following problems at runtime for this air supporting roller, that is, when be located at air supporting roller above substrate pulling force slightly
When micro- excessive, substrate will be attached in air supporting roller, destroy the wet feed structure on substrate.
Summary of the invention
To solve the above-mentioned problems, the present invention to society provide a kind of substrate pulling force it is excessive when, substrate will not be attached to gas
Air-flotation type rotary conveying mechanism in floating roller.
The technical scheme is that a kind of air-flotation type rotary conveying mechanism is provided, including outer roller and interior roller, the interior roller
It is located in the outer roller, the interior roller is communicated with blast pipe, several first through hole is equipped on the interior roller, in the outer roller
Several second through-holes are equipped with, the wind entered from blast pipe outflows after first through hole, using the second through-hole to outer roller
Out, the cavity constituted between the inner surface of the outer roller and the outer surface of the interior roller is divided into several small cavitys, each
The conjunction of the draught area of first through hole corresponding to the small cavity is logical with the second through-hole corresponding to each small cavity
The ratio between conjunction of wind area is less than 1.
As improvement of the present invention, the conjunction of the draught area of first through hole corresponding to each small cavity and each
The ratio between the conjunction of draught area of second through-hole corresponding to the small cavity selects between 0.3-0.8.
As improvement of the present invention, the conjunction of the draught area of first through hole corresponding to each small cavity and each
The ratio between the conjunction of draught area of second through-hole corresponding to the small cavity selects between 0.5-0.7.
As improvement of the present invention, the roll surface of the outer roller includes air bearing supporting surface and non-air bearing supporting surface；Described
Two through-holes are set on the air bearing supporting surface.
As improvement of the present invention, the interconnecting piece of the blast pipe and the interior roller is set to the non-air bearing supporting surface
On.
As improvement of the present invention, the blast pipe is set to the middle part of the both ends of the surface of the interior roller.
As improvement of the present invention, the interior roller and outer roller coaxial arrangement.
The present invention is divided due to using the cavity constituted between the inner surface of the outer roller and the outer surface of the interior roller
It is cut into several small cavitys, the conjunction of the draught area of first through hole corresponding to each small cavity and each small cavity
Structure of the ratio between the corresponding conjunction of draught area of the second through-hole less than 1, in this way, the air pressure outside the second through-hole is far smaller than outer
The interior pressure of the cavity constituted between the inner surface of roller and the outer surface of the interior roller, much less than in pressure in roller, when
When substrate outside second through-hole is close to second through-hole, due to the airflow function of several second through-holes, limited in first through hole
Under the action of system reflux, so that the pressure outside the second through-hole can only be infinitely close to the interior pressure of cavity, without being equal to chamber
The interior pressure of body, so, substrate is impossible to be attached on the surface of outer roller, and the substrate of existing air supporting roller gram has been taken to paste asking for hole
Topic.
Detailed description of the invention
Fig. 1 is the transversal profile structural schematic diagram of an embodiment of the present invention.
Fig. 2 is the axial section structural schematic diagram of the illustrated embodiment of Fig. 1.
Specific embodiment
Referring to Figure 1 and Fig. 2, Fig. 1 and Fig. 2 disclose be a kind of air-flotation type rotary conveying mechanism, including outer roller 1 and interior roller
2, the interior roller 2 is located in the outer roller 1, and the interior roller 2 is communicated with blast pipe 3, on the interior roller 2 be equipped with several first
Through-hole 21, on the outer roller 1 be equipped with several second through-holes 11, from blast pipe 3 enter wind after first through hole 21, then
It is flowed out by the second through-hole 11 to outside outer roller 1, the chamber constituted between the inner surface of the outer roller 1 and the outer surface of the interior roller 2
Body is divided into several small cavitys 12, the conjunction of the draught area of first through hole 21 corresponding to each small cavity 12 and every
The ratio between conjunction of draught area of second through-hole 11 corresponding to a small cavity 12 is less than 1.
Preferably, the conjunction of the draught area of first through hole 21 corresponding to each small cavity 12 and each small chamber
The ratio between the conjunction of draught area of second through-hole 11 corresponding to body 12 selects between 0.3-0.8；The ratio between closed in the area of the two
In 0.3-0.8, there is preferably effect.
Preferably, the conjunction of the draught area of first through hole 21 corresponding to each small cavity 12 and each small chamber
The ratio between the ratio between the conjunction of draught area of second through-hole 11 corresponding to body 12 selects between 0.5-0.7, closed in the area of the two
In 0.5-0.7, there is more preferably effect.
The test result of the area ratio of the two is as follows:
| Area ratio | Effect | Area ratio | Effect |
