Abstract

The utility model relates to a rotary air source distributor for a tyre building machine, which comprises an air source output distributor, a rotary joint, bearings, a wear-resistant O-shaped ring and a retaining ring. The rotary air source distributor is characterized in that more than two thread output breathing holes are distributed on the side surface of a base of the air source output distributor, and an input interface and an output interface are respectively arranged on the side surface; and the rotating joint is a barrel sleeved in the axle core of the air source output distributor, the retaining ring is installed in the axle core of the outer edge of the rotary joint, a pair of the bearings are respectively installed at the both ends in the barrel and are in contact with the axle cores, and the wear-resistant O-shaped ring is embedded on a groove on the inner wall of the barrel. The utility model has the advantages that since the bearings at both ends of the rotary joint are matched with the axle cores, the wear-resistant O-shaped ring is not easy to be worn; since both the input interface and the output interface are arranged on the side surface, the inner holes in the axle cores are not deep, and the phenomenon of sagging and deflection of the axle cores is eliminated; the rotary air source distributor is simple in structure and is more economical and more convenient; and the maintenance is convenient, and the production efficiency is improved.

Description

Tyre building machine rotation source of the gas distributor

Technical field

The utility model belongs to the rubber tyre forming machine, particularly a kind of improvement of source of the gas distributor.

Background technique

Original source of the gas distributor adopts the ventilation of ventilation mandrel, its input output joint is in the distributor both ends of the surface, the ventilation mandrel is elongated, sagging easily after the assembling, beat, distortion, swivel joint very easily forces the mandrel afterbody that bigger beat takes place when being connected with the source of the gas distributor, thereby reduced the working life of O type circle, sometimes even the disastrous effect that the mandrel distortion is scrapped takes place; The mandrel endoporus is darker in addition, and the user must producer provide because this hole is difficult for processing as changing mandrel; When O type circle wearing and tearing must be changed, must turn off that source of the gas is pulled down swivel joint and the source of the gas distributor is just replaceable, cumbersome.

Technology contents

For sagging easily, beat, the distortion that overcomes existing source of the gas dispensing device, the life-span is short, change shortcoming such as trouble, and the spy provides a kind of source of the gas dispensing device of model utility.

The technical solution of the utility model is: the utility model tyre building machine rotation source of the gas distributor, and this device includes source of the gas output distributor, swivel joint, bearing, wear-resisting O type circle, snap ring; Two above screw threads output vents of described source of the gas output distributor base side distribution communicate with two vents of axle core respectively interior, are connected with cylinder outside, and base is fixed on the panel, and input interface and output interface are all in the side; Described swivel joint is one cylindric, be nested with on source of the gas output distributor axis core, the axle core is short for its length, with swivel joint outward edge axle core on a snap ring is installed, two screw thread input vents of drum surface and pressurized container join, in cylinder two ends respectively be equipped with a supplementary bearing with the axle core contact, on the cylinder inner wall groove, be embedded with wear-resisting O type circle.

The beneficial effects of the utility model are:

1. because input, output interface is all in the side, axle in-core hole is not dark, and sagging, the beat of a core can not take place;

2. because the swivel joint bearings at both ends matches with the axle core, O type circle is difficult for being worn;

3. simple in structure, more economical and practical;

4.O the type circle only needs snap ring taken away the swivel joint cylinder taken off to change new O type circle and get final product in case wearing and tearing must be changed, it is convenient to keep in repair, and enhances productivity.

The utility model will be further described below in conjunction with the drawings and specific embodiments.

Description of drawings:

Fig. 1 is a cross-sectional schematic of the present utility model.

Fig. 2 looks schematic representation for the utility model right side.

Embodiment

This device includes source of the gas output distributor 1, swivel joint 2, bearing 3, wear-resisting O type circle 4, snap ring 5 as shown in Figure 1 and Figure 2;

Input interface

7,8 and

output interface

9,10,11,12 are all in the side, and axle in-core hole is not dark, and sagging, the beat of a core can not take place; Described swivel joint 2 is one cylindric, is nested with on 1 core of source of the gas output distributor, and two ends respectively are equipped with a supplementary bearing 3 and are contacted with a core in cylinder, are embedded with wear-resisting O type circle 4 on the cylinder inner wall groove, prevent to lose heart; Source of the gas output distributor 1 base side distributes four and goes up screw thread vent 9 as shown in Figure 2,10,11,12,

screw thread vent

9,11 communicate with axle core one venting channels,

screw thread vent

10,12 communicate with axle core another venting channels, source of the gas follower 1 base is fixed on the panel, when the driven by motor panel rotates, source of the gas follower 1 rotates with panel, swivel joint 2 is because the effect of bearing still remains on original position, the inlet opening 7 like this, 8 keep original position motionless, gas is by swivel joint inlet opening 7,8 enter two venting channels of a core respectively to

delivery outlet

9,11 and 10,12 respectively with panel on two cylinder air inlets be connected with relief opening, thereby drive the cylinder action.

Claims

1. a tyre building machine rotates the source of the gas distributor, and this device includes source of the gas output distributor, swivel joint, bearing, wear-resisting O type circle, snap ring; It is characterized in that: two above screw threads output vents of described source of the gas output distributor base side distribution, communicate with two vents of axle core respectively interior, be connected with the cylinder inlet, outlet outside, base is fixed on the panel, and input interface and output interface are all in the side.

2. according to the described tyre building machine rotation of claim 1 source of the gas distributor, it is characterized in that: described swivel joint is a cylinder, be nested with on source of the gas output distributor axis core, in cylinder two ends respectively be equipped with a supplementary bearing with the axle core contact, be embedded with wear-resisting O type circle on the cylinder inner wall groove, two screw thread inputs of drum surface vent is connected with pressurized container.

3. according to the described tyre building machine rotation of claim 1 source of the gas distributor, it is characterized in that: a snap ring is installed on swivel joint outward edge axle core.
