Abstract

The utility model discloses a gas distributor. A compression gas inlet and a compression gas outlet are both arranged on a rotating shaft, an axial blind hole is communicated with a compression gas input pipe by a rotary joint, when the gas distributor works, compression gas enters the axial blind hole through the rotary joint and flows out through a gas outlet joint at the position of a gas outlet hole so as to complete the compression gas distribution operation, and an outer ring, a corresponding bearing and a sealing ring are not required, and therefore, compared with the prior art, the gas distributor has the beneficial effects that firstly, due to the removal of the outer ring, the corresponding bearing and the sealing ring, the distributor has a simple structure and the production cost is greatly reduced; secondly, the sealing ring is not required, the rotating resistance of the rotating shaft can be greatly reduced, and the phenomenon of air leakage caused by abrasion of the sealing ring is avoided; thirdly, the bearing is removed, the possibility that the product is polluted is reduced.

Description

A kind of gas distributor

Technical field

The utility model relates to a kind of gas distributor of bottle placer.

Background technology

Gas distributor is the important component part of the central dispense device of rotary filling machine, for carrying out sharing out the work of pressure gas.As shown in Figure 1, existing gas distributor mainly comprises the outer shroud 10 being fixed on fixed mount 30, by bearing 80, be rotatably arranged on the S. A. 20 on the inwall of outer shroud 10, and be arranged on S. A. 20 electric power source distribution device 70 rotating with S. A. 20, the bottom of S. A. 20 is fixed on the swivel mount (not shown) of central dispense device and can rotates with swivel mount, during work, S. A. 20 rotates with swivel mount, pressure gas enters from the inlet suction port 40 of outer shroud 10, then the formed air drain (not shown) in the gap between outer shroud 10 and S. A. 20 flows into the gas passage 201 of S. A. 20, finally from the air outlet adapter 50 of S. A. 20, flow out, complete the distribution of pressure gas.

Though this structure can complete sharing out the work of pressure gas preferably, but still have weak point, as: 1, its admission port and air extractor duct are separately positioned in relative rotation on outer shroud 10 and S. A. 20, and bearing 80 and seal ring 60 need be set between outer shroud 10 and S. A. 20, the structure of whole gas distributor is comparatively complicated, and corresponding productive costs is high.2, during S. A. 20 rotation, seal ring 60 can produce larger resistance to S. A., and meanwhile, seal ring 60 can be rotated axle 20 wearing and tearing, and seal ring 60 is while may wear to a certain degree, can be directed at pressure gas and leak.3, the easy polluted product of the lubricating oil of bearing 80.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, the gas distributor that productive costs is low, and rotational resistance suffered during its work is less, there will not be pressure gas to leak, and can reduce the contaminated possibility of product.

A kind of gas distributor described in the utility model, comprise the S. A. being arranged on swivel mount, the end face of described S. A. has axial blind hole, the line of centers of this axial blind hole overlaps with the rotation centerline of S. A., the admission port of axial blind hole is provided with for leading to the swivel joint of pressure gas input pipe and axial blind hole, the sidewall of S. A. has the air gate that is communicated with blind hole, and the air extractor duct of air gate leads to by air outlet adapter and pressure gas delivery pipe.

The utility model is all arranged on S. A. by the admission port of pressure gas and air extractor duct, and by swivel joint, axial blind hole and pressure gas input pipe are led to, during work, pressure gas is from swivel joint enters axial blind hole, can flow out from the air outlet adapter of air gate, complete sharing out the work of pressure gas, and need not use outer shroud and corresponding bearing and seal ring, therefore, compared with prior art, the utlity model has following beneficial effect: 1, omit after outer shroud and corresponding bearing and seal ring, can make the structure of distributing box become more simple, significantly reduce corresponding productive costs.2, need not use seal ring, can significantly reduce S. A. suffered resistance of when rotation, can't occur because of the disappointing phenomenon of ring wear.3, omit after bearing, can reduce the contaminated possibility of product.

Accompanying drawing explanation

Fig. 1 is the structural representation of prior art.

Fig. 2 is structural representation of the present utility model.

The specific embodiment

As shown in Figure 2, described gas distributor, comprise and be arranged on swivel mount (not shown) and the S. A. 1 that can rotate with swivel mount, and be arranged on the electric power source distribution device 2 on S. A. 1, the end face of described S. A. 1 has axial blind hole 11, the line of centers of this axial blind hole 11 overlaps with the rotation centerline of S. A. 1, the admission port of axial blind hole 11 is provided with for leading to the swivel joint 3 of pressure gas input pipe 5 and axial blind hole 11, the rotating part of swivel joint 3 can rotate with S. A. 1, the part that swivel joint 3 is not rotated keeps static together with pressure gas input pipe 5, this pressure gas input pipe 5 is laid and is supported by fixed link 7 along fixed link 7, the sidewall of S. A. 1 has the air gate 12 that is communicated with blind hole 11, the air extractor duct of air gate 12 leads to by air outlet adapter 4 and pressure gas delivery pipe 6.During work, pressure gas, from swivel joint 3 enters axial blind hole 11, can flow out from the air outlet adapter 4 of air gate, completes sharing out the work of pressure gas.

Claims

1. a gas distributor, comprise the S. A. being arranged on swivel mount, it is characterized in that: the end face of described S. A. has axial blind hole, the line of centers of this axial blind hole overlaps with the rotation centerline of S. A., the admission port of axial blind hole is provided with for leading to the swivel joint of pressure gas input pipe and axial blind hole, the sidewall of S. A. has the air gate that is communicated with blind hole, and the air extractor duct of air gate leads to by air outlet adapter and pressure gas delivery pipe.
