figure 2 shows the interaction of the working body with the material to be processed.

Device for impregnation of sheet materials (see figure 1, 2) contains a bath 1 for working compositions, fluted shaft 2 mounted and immersed in a bath 1, for applying the working of trains at idle branch of the supply conveyor 3, the pinch roller 4 to ensure constant contact with the grooved shaft 2 and located parallel to the axis of the grooved shaft 2 for the no branch of the supply conveyor 3. The device 5 to create a hydrodynamic wedge is installed on the tub 1 with the possibility of lateral movement and oscillating movement to ensure Lou is our fill depressions grooved shaft 2. The supply conveyor 3, is made of absorbent material such as “lycra”, mounted on a frame (not shown in figure 1) to four shafts: drive 6, intermediate 7, tension 8. The working body 9 made in the form of a relief plane has guides 10 in the form of a “dovetail”or metal sleeve with the inner surface of the antifriction material and is installed with the possibility of reciprocating motion in a vertical plane by means of the crank 11, made in the form of a crankshaft with a small eccentricity. In the upper part of the base is mounted auxiliary conveyor 12, is made of porous material over the working (lower) branch of which is mounted on the frame (not shown) elastic counterbody 13 to provide multiple alternating bending intermediate product 14 in the plane perpendicular to its direction of motion. The auxiliary conveyor 12 is mounted on two shafts: stretch 8, the driving shaft 6. In addition, the device for impregnation of sheet material provided with a smooth shaft 15, mounted directly at the beginning of the working branch of the supply conveyor 3 and is designed as a knife shaft with blunt cutting edges to reduce the possibility of jams and uneven processing of the intermediate product 14, and a device 16 for pickup none is of brigata 14, located at the end of the working branch of the supply conveyor 3 and allows you to automatically remove the processed intermediate product 14 and if you do not require further processing, to put it in a foot.

Device for impregnation of sheet material works as follows (see figure 1, 2).

In the bath 1 serves the personnel, include a motor (not shown in figure 1) drive the conveyors 3, 12, smoothing the shaft 15 and the electric motor (not shown) drive the grooved shaft 2. Rotating, fluted shaft 2 through 5 to create a hydrodynamic wedge and roller 4 transfers the required amount of composition on the supply conveyor 3. The supply conveyor 3 is saturated with the composition and after 5 min ready.

At the site loading sheet materials prefabricated 14 (see figure 2) is placed on a saturated working structure of the feeding conveyor 3 hair cover up. Moving together with the conveyor 3, the intermediate product 14 extends through smoothing of the shaft 15, and then is captured by the auxiliary conveyor 12 and a driven conveyors 3 and 12 hits in the treatment area, where it exerts a mechanical effect of the working body 9 in the form of a relief surface, which together with the conveyors 3 and 12 provides multiple alternating bending effects is a journey in the transverse direction and cyclic tension-compression in the longitudinal direction. The periodic alternation of compression, bending and stretching provides intensive movement of workers compositions of the thickness of the feeding conveyor 3 in the thickness of sheet materials, such as leather fabric intermediate product 14 (see figure 2).

In addition, the simultaneous action of the conveyors 3 and 12 provides the effect peristil tissue, which leads to a more uniform distribution of the working compositions according to the volume of the sheet material, thereby intensificar processing. The interaction of a work body 9, prefabricated sheet 14, the elastic counterbody 13 and conveyors 3 and 12 achieved the effect of “sponge” and the hydrodynamic effect.

After exiting the work zone prefabricated sheet 14 is removed from the conveyor belt 3 by means of the device 16 is placed over the hides. At the time when the processing of a single sheet of semi-finished product, is preparing for the next, which is loaded into the device sequentially, without interruption. The loop is repeated.

The proposed device for impregnation of sheet materials in comparison with the prototype (A.S. No. 1837302, MKI With 14 15/00, 1989) will reduce the flow rate of the emulsion associated with the spray and accuracy of dosing, the use of more economical method of application of working on the supply conveyor 3 by means of the grooved shaft 2, device 5 to create hydrody omicheskogo wedge and roller 4. The device performs the checkpoint processing, which allows to reduce time wasted on loading-unloading semi-finished product, as well as start-stop motor drive of the working body. In addition, the device 16 for removal of semi-finished product allows to exclude the participation of the worker in the process of removal and storage of the finished semi-finished product, which enables the installation of a device for impregnation of sheet materials in an automated line. Easy maintenance due to the use of this device is not complicated and does not require fine tuning of structural components and elements. The reliability of the device is achieved by applying a more durable one-piece relief plane 9 and the high reliability of the individual components. High quality processing is achieved by using two conveyors 3 and 12, providing a secure grip of the semi-finished product and not allowing his injuries, as well as smoothing of the shaft 15, which prevents the collapse of the semi-finished product.

The device allows you to more effectively carry out the process of impregnation material working compositions, to intensify the treatment, which allows to make a conclusion about the relevance of the proposed invention, the criterion of “industrial applicability”.
