Description

one

The invention relates to the field of construction india stria, namely to the final finishing of the surfaces of the building products of predominantly cassette production.

A device for finishing the surfaces of building products is known, which includes a distribution device for feeding the solution, a shading mechanism made in the form of a rotor with blades of plasterboard and spatulas for cleaning and GRINDING.

This device is characterized by complexity of the design and does not provide high quality surface finishes.

These disadvantages are due to the following features of the known device.

In the zone of application of the solution, it is necessary to completely seal the space between the protective casing and the product to be finished, since splashing of the solution by the rotor is unavoidable. This does not allow to finish building products with different linear dimensions in height and products with through ;: openings and niches.

For the continuous supply of the solution during the processing of the product, a collapsible and unreliable in operation mortar pump is used, stopping of which interrupts the operation of the entire installation.

Use of mortar pump for hearth2

This solution does not allow for the use of viscous solutions and thus also prevents the quality of the finish, since less viscous solutions give greater volume shrinkage and, consequently, less liquid sinks.

The purpose of the invention is to simplify the design of the device and improve the quality of finishing products.

This is achieved by the fact that, in the proposed construction, the working bodies of the mechanism and the solution of the solution and the mechanism of the final finishing of the products are made in the form of an endless closed circuit with fixed on it

flexible spatulas, the spatulas are made in the shape of trapezpie, and the working edges of the spatulas of the mechanisms for applying the solution and the final finishing are set at an angle of 15-20 ° n respectively 160-165 ° to the direction of the two-way product.

FIG. 1 shows schematically the proposed device, a general view; in fig. 2 - the same, VIEW from above; in fig. 3 shows a section along the .4-L in FIG. 2

The device for finishing the surfaces of building products, mainly cassette production, consists of a device 1 for wetting surfaces with water, a mechanism 2 for applying a solution to the surface of a construction product, a mechanism 3

final finishing of the product and the feeder 4, made in the form of a trough.

The mechanisms 2–3 of the application of the solution and the final finishing of the product (see FIG. 3) consist of water-mounted 5 in pairs and 5 sprockets, chains 7, drives 8 from electric motors, spatulas 9 attached to chains x 7, and support rollers 10.

To ensure unhindered passage of the workpiece 11 into the working parts zone, the spatulas 9 are made in the form of a trapezium and are installed so that the working edge of the spatula of the solution application mechanism is 15–20 ° and the spatula of the final finish is 160–165 ° C. the direction of movement of the product.

The piece is moved relative to the working bodies of the transport conveyor 12.

The device works as follows

The product 11 is installed by a crane on the transport conveyor 13. With the help of the device 1 it is moistened with water from one or two sides to the full height. With further product includes the drive mechanism 2 application of the solution.

The solution, captured by the spatula of the mechanism 2 from the trough in the process of running around the chain 7 around the sprockets, is applied and simultaneously rubbed into the holes on the surface of the article 11 and not upwards.

Then the product enters the working parts of the mechanism of the final finishing, whose spatulas move from top to bottom and additionally rub the solution into the pores and polish the surface and remove the excess solution, which is discharged into the trough 4. Similarly, the surface of the product is processed from the other side.
