The invention relates to the processing of a polymeric material., Can be used to cool ribbon polymeric materials, in particular, a long rubber cloth, and is an improvement of the known device described in the author, St. No. 1502364.

The purpose of the invention is to increase the reliability of the device. ; -, FIG. 1 shows the device, general view, cross section; figure 2 is a view of And figure 1; nafig.Z-type B nafig.2; figure 4 is a cross section bb In Fig.2; Fig.5-section GG in figure 1, the element.

The device comprises a chamber 1 for creating a dynamic cushion under the material in the form of a truncated pyramid, mounted on it a carrier plate 2 with cells 3, made with

sloping in the direction of transporting the polymer tape 4. In the bases of the cells 3, the holes 5 are evenly arranged in the form of confusors, interconnected by channels 6. The cells 3 are interconnected by a system of closed channels 7. Channels 7 are made above the base level of the cells 3 offset from each other in the transverse direction to the width of the cell 23. The longitudinal axes of symmetry of the upper cut-off of the feeding holes 5 and the transverse edge of the channel 7 of the bottom wall 8 of the cell 3 are located on a common horizontal level. In the carrier plate 2, the sealing channels 9 are made, in which the liquid flows from the drain channels 10. The branch pipes 11 are designed to exit the working agent from the chamber 1, are installed in the supply channels 9 of the carrier plate 2, made of SL Y S

The yens are in the form of diverting fittings with threaded sections for installation in the carrier cast 2 and are equipped with gears 12 mounted on their connection with the rotational mechanism (not shown). The longitudinal axis of symmetry of each fitting 11 is in the same plane with the lower face of the corresponding cell 3 and perpendicular to the plane of the carrier plate 2, with the outer diameter of fitting 11 greater than the width of the feed channel 9. All gears 12 are located in a common plane and are covered by a chain transmission 13. Inlet the coolant into each cell 3 is carried out in a staggered order along the powering fitting 14, which is made in the carrier plate 2, in which the liquid flows from the corresponding fitting 11 through a flexible hose (not shown). In places of interface of the outer wall of the supply channels 9 with the threaded section of fittings 11, evacuation channels 15 are made in it, through which the sealing channels 9 are connected with drain channels 10.

The device comprises a chamber 16 for the surface treatment of a polymeric material, made in the shape of a truncated pyramid. The chamber 16 is equipped with an upper plate 17 mounted therein with cut-off visors, 18, installed longitudinally on the non-working surface of the plate 17. The plate 17 is made parallel to the plate 2. On the working surface of the upper plate 17 there are cells 19, in the bases of which holes 20 are made environment of the chamber 16. The holes 20 are made in the form of diffusers. The holes 20 are interconnected by a system of channels 21, and the cells 19 are interconnected by a system of open channels 22, the channels 22 are made above the base level. cells 19 offset from each other by the width of the cell 19 in the transverse direction. The longitudinal axes of symmetry of the upper cut-off of the feeding holes 20 and the transverse edge of the channel 22 of the bottom wall 23 of the cell 19 are located on a common horizontal level. Cooling supply

The cells in the cells 19 are carried out in a staggered order along the powering fittings 24, which are made in the upper plate 17, into which the liquid comes from a common collector (not shown). The working surface of the top plate 17 is equipped with a pro. long sectional transom 25, allowing to organize access to the transported rubber sheet 4 along the entire length of the device. Discharge of the spent working environment is carried out through

a gap 26 in the slab 17. The cells 3 have niches 27. The channels connecting the cells of each of the plates are made higher than the base level by an amount A, which is determined from the following relationship: D I,

where I is the width of the cell in the longitudinal direction;

p is the angle of inclination of the device to the horizon (figure 5).

The device works as follows.

5 B chambers 1 and 16 are supplied with compressed air. At the same time, having passed through the holes of 5 cells 3 of the inclined plate 2, the air falls under the web of polymeric material 4, for example, a tread, and creates an air layer here. In the slots 19 of the inclined top plate 17, liquid refrigerant, for example, water, is supplied through fittings 24. Since the transverse symmetry axes of the upper cut of the feed holes 20 and the transverse edge of the channel 22 of the bottom wall 23 of the cell 19 are located on a common horizontal level for a given cell of the plate 17, water simultaneously feeds the holes of the top plate of the 17 plate simultaneously. Air After passing through the diffusers of the openings 20, it disperses the Avoiding flow of water into jets of water dust, which are used to treat the upper surface of the tread 4. The exhaust air5 is freely displaced into the environment through the openings of the devices and for the entrance and exit of the tread band, as well as into the gaps 26 of the plate 17. The droplets deposited on the polymer are blown away by jets of working medium from its surface and along the cutting visors 18 flow into confusing channels 9 of the carrier plate 2. Driving all the gears 12 chain transmissions 13, for example, with

5, using an electric actuator (not shown), the nozzles 11 are moved along the thread until the upper section of each nozzle 20 drops below the horizontal level of the liquid in the supply

0 channel 9. In order to prevent rotational movement from being transmitted to the feeding nozzles 14, the connecting hoses can be provided with a helical (helical) corrugation. Since the longitudinal axis of the symmetry of the fittings 11 is located in one plane in the lower face 8 of the corresponding cell 3, and its upper section is above the upper section of the holes 5 of the cell by an equal amount, the water from the supply channels 9 through the fitting 11 and the flexible hose (not shown) through the feed nipple 14 enters the niche 27 of the corresponding cell 3, made on a horizontal level common to this cell, and feeds all the openings of the cell at once through the channel system 6. At the same time, trying to fill the confuser of the openings 5, water is being ejected, dispersed by air streams into small droplets. Water is sprayed onto the dust to the supporting surface of the cooled material 4 and is deposited on it, after which it is blown off by jets of working medium into the feed channels 9. Mixing with water from the tread upper surface treatment, the liquid partially flows through fittings 11 to re-feed the corresponding cells 3, and part of the evacuation channels 15 flows into the drain channels 10, from where they are diverted for processing.

Next, the cooling cycle is repeated.
