(54) DEVICE FOR PAINTING PRODUCTS

one

This invention relates to spray-dyeing of products of complex configuration.

A device for painting articles is known, comprising a shaft with sprays hinged on it, a drive for rotating the nozzles around the shaft, and a drive for swinging them along the axis of the shaft associated with the nozzles through the lever system 1.

A disadvantage of the known device is the complexity of the design of the swing mechanism, which is made in the form of a complex multi-link lever system containing hinged joints of its elements.

The closest to the proposed technical essence and the achieved effect is a device for painting products, containing a pipe installed on a base in bearings in the form of spherical bearings with nozzles fixed on it, consisting of two parts along the length of which are pivotally connected to each other by means of a connecting hollow coupling having a swing mechanism 2.

The disadvantages of this device include the use of energy supplied to the drive of the swing mechanism, which entails a complication of the structure.

The purpose of the invention is to simplify the design of the device by using a paint material as a working medium for driving the swing mechanism.

The goal is achieved by the fact that

, Q in a device for painting products containing a pipe installed on a base in bearings in the form of spherical bearings with nozzles attached to it, consisting of two parts along the length of which are articulated by means of

15 a hollow coupling having a swinging mechanism; the coupling swing mechanism assembly is made in the form of a slider installed in the coupling cavity with a spring-loaded diaphragm fixed at the end, and

20, a channel is made in the coupling housing that connects the coupling cavity with the paint supply source, while the second end of the rod is rigidly fixed to the base.

FIG. 1 shows a device for painting products, a general view; in fig. 2 -

The clutch swing mechanism assembly 1 in FIG. one; in fig. 3 is a view A of FIG. one.

The device for painting products comprises a housing 1, in which in supports 2 and 3 in the form of spherical bearings 4 there is a pipe with fixed sprayers 5. The pipe consists of two parts 6 and 7 along the length that are hinged together by means of a connecting hollow 8.

In the cavity 9 of the coupling 8 a rod 10 is installed with a spring-loaded spring 12 fixed on the end of my 11 a diaphragm. In the case of coupling 8, a channel 13 is made, co-cavity 9 of the coupling 8 with an ink supply source 14.

To control the supply of paint and varnish material to the cavity 9 of the coupling 8 and to the nozzles 5, control valves 16-18 are used. At the outer ends of the parts 6 and 7 of the pipe are fixed gears 19, interacting with toothed racks 20, which are fixedly mounted on the side wall of the chamber 1.

The device works as follows.

The product to be painted is suspended on a conveyor (not shown) and is stirred inside the chamber 1 along its axis. With valves 17 and 18 open, paintwork material is supplied through pipelines m in parts b and 7 and to the spray gun 5 and also to the cavity 9 of the coupling 8. The valve 16 must be closed. Under the action of overpressure of the paintwork material acting on the diaphragm 11, the coupling 8 moves upwardly against the rigidly fixed brush 10, compressing the spring 12. Simultaneously with moving upwards, the pipe parts 6 and 7 rotate around their axis due to gears 19 and the toothed rack 20. When when reaching the upper extreme position w (equal to the stroke of the swing 11), the valve 16 is opened and the valve 17 is closed. The valves 16 and 17 can be controlled from the limit switches triggered at the extreme upper and lower positions of the coupling 8 (limit switches (not shown). The cavity 9 of the coupling 8 is connected through the pipe 14 and the valve 16 to the drain. Pressure The cavity 9 of the coupling 8 falls. The spring 12 expands and, acting on the coupling 8, moves it down from the stem 10 to the lowest position. The paintwork material from the cavity 9 of the coupling 8 is displaced into the drain.

When the coupling 8 reaches its extreme lower position (equal to the swing stroke), the valve 16 is closed and the valve 17 is opened. The paints and varnishes are again supplied under pressure to the cavity 9 of the coupling 8. Thus, the parts 6 and 7 are rotated with the sprayers in a vertical plane and rotated around their axis.

The proposed implementation of the pump tube swing mechanism in the device for painting products allows to simplify the design of the device and at the same time use paintwork material as a working medium for driving the swing mechanism, which simplifies and reduces the cost of operation of such devices.
