Utility model content
To solve the above-mentioned problems, the utility model to society provide a kind of substrate pulling force it is excessive when, substrate will not paste
Air-flotation type rotary conveying mechanism in air supporting roller.
The technical solution of the utility model is: a kind of air-flotation type rotary conveying mechanism, including outer roller and interior roller are provided, it is described
Interior roller is located in the outer roller, and the interior roller is communicated with blast pipe, several first through hole is equipped on the interior roller, described
Outer roller is equipped with several second through-holes, and the wind entered from blast pipe is after first through hole, using the second through-hole to outer roller
Outer outflow, the cavity constituted between the inner surface of the outer roller and the outer surface of the interior roller are divided into several small cavitys,
The conjunction of the draught area of first through hole corresponding to each small cavity and the second through-hole corresponding to each small cavity
The ratio between the conjunction of draught area less than 1.
As the improvement to the utility model, the conjunction of the draught area of first through hole corresponding to each small cavity with
The ratio between the conjunction of draught area of second through-hole corresponding to each small cavity selects between 0.3-0.8.
As the improvement to the utility model, the conjunction of the draught area of first through hole corresponding to each small cavity with
The ratio between the conjunction of draught area of second through-hole corresponding to each small cavity selects between 0.5-0.7.
As the improvement to the utility model, the roll surface of the outer roller includes air bearing supporting surface and non-air bearing supporting surface；Institute
The second through-hole is stated to be set on the air bearing supporting surface.
As the improvement to the utility model, the interconnecting piece of the blast pipe and the interior roller is set to the non-air bearing branch
On support face.
As the improvement to the utility model, the blast pipe is set to the middle part of the both ends of the surface of the interior roller.
As the improvement to the utility model, the interior roller and outer roller coaxial arrangement.
The utility model is due to using the cavity constituted between the inner surface of the outer roller and the outer surface of the interior roller
Be divided into several small cavitys, the conjunction of the draught area of first through hole corresponding to each small cavity with it is each described small
Structure of the ratio between the conjunction of draught area of second through-hole less than 1 corresponding to cavity, in this way, the air pressure outside the second through-hole is much small
The interior pressure of the cavity constituted between the inner surface of outer roller and the outer surface of the interior roller, much less than in pressure in roller
Power, it is logical first due to the airflow function of several second through-holes when the substrate outside the second through-hole is close to second through-hole
Under the action of the limitation reflux of hole, so that the pressure outside the second through-hole can only be infinitely close to the interior pressure of cavity, without etc.
In the interior pressure of cavity, 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 hole
The problem of.
Detailed description of the invention
Fig. 1 is a kind of transversal profile structural schematic diagram of embodiment of the utility model.
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
