2, the painting chamber according to claim 1, characterized in that, in order to improve performance, a disk is mounted on the rotational drive shaft, under which is placed a perforated annular tube for supplying compressed air, with which the rotating device is provided.

The invention relates to painting equipment, namely to spray-through painting chambers with a working place outside the chamber, which is part of the painting plots used in various folk goods for painting products using the method of pneumatic disintegration Famous painting chamber :, comprising a frame with a turntable horizontally mounted on the drive shaft for the product's spreading and a spray gun with a drive for its reciprocating movement along vertically mounted guides, and The turntable shaft is connected to the power CYLINDER l. However, such a painting chamber has a low productivity due to manual loading and loading of the products being processed. Moreover, due to the uneven rotation of the table from the ram with the pusher, uneven coloring of the products is obtained. At the same time, since the support of the table is load carrying, it is necessary that the drive shaft and the pusher have sufficient strength, and this entails an increase in their dimensions and, consequently, in the dimensions of the entire chamber. The closest to the proposed technical essence and the achieved result is a spray-type painting chamber comprising a housing with transport and working straps, a bath with a hydraulic filter installed on it, a ventilation device, a conveyor with suspensions and a rotary device with a rotational drive H. The disadvantage of the spray booth is that it has rather large overall dimensions and occupies large production areas. The purpose of the invention is to reduce the size and metal consumption of the camera. The goal is achieved by the fact that in a painting chamber, a through passage type comprising a housing with transport and working openings, a bath with a hydraulic filter installed on it, a ventilation device, a conveyor with suspensions and a rotary device with a rotating drive, the rotator is made in the form of mounted on a shaft The rotation of the guides with bent ends, forming between them a gap for inserting into it a protrusion made in the lower part of the suspension. In addition, a disk is mounted on the rotational drive shaft, under which an annular perforated tube for supplying compressed air, which is equipped with a rotating device, is placed. FIG. 1 schematically shows a painting chamber, general view; FIG. 2 is a side view; FIG. FIG. 3 is a section A-A in FIG. 1; FIG. 4 is a section B-B in FIG. 1; The spray booth-type painting chamber comprises a housing 1 with a worker 2 and 3 transport openings, a chain one. a conveyor with carriages 4 for moving along the monorail 5; A ventilation device b is installed on the camera body on top, including a fan and air ducts (not labeled), the camera includes a bath 7 with hydro-filter-t installed on it. rum 8. For the circulation of water, the chamber contains a hydraulic system including an electrohydraulic pump 9 and pipelines 10. In addition, the chamber includes a rotary device with a rotational drive. Moreover, the rotating device is installed in the center of the chamber and made in the form of guides 12 mounted on the rotational drive shaft 11 with bent ends. To install the products to be painted, the conveyor has lattice hangers 13 with a protrusion 14 in their lower part. Direction 12 forms a gap between them for inserting the protrusion 14 under the weight 13 into it. Under the rotary device guides 12, a disk 15 is rigidly attached to which houses an annular perforated tube 16 for supplying compressed air, which is attached to the body of the chamber and connected to the compressed air line. Each suspension 13 is pivotally connected to the carriage 4 of the chain conveyor, which allows the suspension to rotate around a vertical axis. The drive of the rotator includes a gearbox 17 or a system of gearboxes and an electric motor 18w In working 2 on the camera body of the eacretronic; brackets 19 for the installation of colors. Spread out the firs 20. The camera also includes a control system 21 for its operation.

The work of the paint roller is carried out in the following way.

The products to be painted 22 are mounted on the trellis pendants 13 and move the & c. Working opening 2 to the chamber. At the entrance of the suspension 13 into the camera turning the device off

but, the direction of the 12 pivot

devices parallel to the monorail 5. After the protrusion

14 of the suspension 13 enters the gap between the guides of the rotator 12, the conveyor is stopped and the rotary actuator is turned on. At the same time begin coloring products from the working opening. Painting is carried out either by automatic paintbrushes, if the painted products have a not too complicated surface or are hand-made .:

Simultaneously with the inclusion of paint sprayers, I am feeding into the perforated ring tube 16. compressed, creating an air curtain preventing paint dust from falling on the rotary device and rotational drive. Since the forces of interaction between the projections of the suspensions and the guides of the rotator are small (not HiaMHoro more than the forces TpeliHH of the swing of the articulated device of the suspensions), the shaft width, dimensions of the gearbox and the power of the electric motor can be significantly reduced in comparison with known cameras .

The rotational speed of the suspensions is re-adjusted by varying the rotational speed of the engine.

The unsettled particles of paint coatings, together with the air, are drawn in under the action of the ventilation device 6, pass through the water curtains of the hydraulic filter 8 and get into the bath 7 along with the water 7. Circus; Water is supplied by an electrohydraulic by a pump 9 and pipelines 10. After turning the suspension to the required angle, for example, 540 °, 720f which depends on the desired thickness of the paint coating, the rotator is stopped and the conveyor is set in motion.

In order to insert the projections 14 of the suspensions into the gap between the guides 12 of the rotator, in the case of a slight deflection of the suspensions from the vertical plane, the guides 12 of the rotator are made with bent ends. .

The use of this invention provides an improvement in the performance of the spray booth, as well as saving production space by reducing the volume of XM1 to a minimum size.

Expected economic effect; is about 14 thousand rubles. in year.
