Description

The invention relates to equipment for applying two-sided coatings to rolled materials, for example, asphalt resin, and can be used in various areas of the national economy.

The aim of the invention is to provide ease of maintenance by simplifying the adjustment of the thickness of the covering layer and increasing the productivity by reducing the number of edges of the web.

layer across the width of the canvas; in fig. 3 and - adjustment knots, cut; in fig. 5 - cylindrical liner; in fig. 6 - slider.

Device for coating rolled material contains bath

1 for the coating mass, the guide roller 2, the scraper 3, the spreading roller k and the mechanism 5 for applying and calibrating the coating layer consisting of a support roller 6 and mounted on the rotary frame 7 of the submersible 8, lower 9 and upper 10 calibrating rollers, the adjustment unit - the gap between the upper calibrating roller and the web of the material being processed and the unit for controlling the uniformity of the application of the coating layer across the web width.

to

The knot for adjusting the gap between the upper calibrating roller and the material web is made in the form of a worm gear, the worm to 11 of which is mounted on the frame 7 and has a handwheel 12 at the end, and the worm gear 13 is mounted on the pin 14 of the upper calibrating roll 10 installed with eccentricity.

The unit for adjusting the uniformity of application of the coating layer across the width of the web contains supports 15 for pins 14 of the upper sizing roller 10, having cylindrical inserts 1b with radial holes 17 for pivots 14. Liners 1b are installed inside sliders 18, in which also holes 19 for pivots 14 are also made The sliders 18 are connected to compression springs 20 installed in the supports 15. A pair of screw 21 is mounted on the frame 7, the screw 22 of which passes through the hole in the support 13 on the drive side and is connected to the slide 18. At the end of the screw 22 there is a steering wheel 23. Rama oedinena pnovmotsilindra with rod 24 and is rotatable around the axis 25..Ustroystvo operates as follows.

Pneumatic cylinder 24 rotate the frame 7 around the axis 25, moving to the upper position of the submersible 8 and calibrating 9 and 10 rolls. The canvas material is passed under immersion 8 .and calibrating 9 and 10 rollers and above the support 6 and spreading 4 rollers, then lower the frame 7 and turn on the drive. The canvas immersed in the covering mass envelops the submersible roller 8, slides along the surface of the lower gauge roller 9 and passes into the gap between the upper gauge 10 and the bottom 6 rollers. When processing a material having the same thickness across the width of the web, the thickness of the covering layer is adjusted by turning the swirl 10 around its axis using a worm gear,

Due to the eccentricity of the upper sizing roller, its working surface then approaches, then moves away from the support roll 6. If a material whose thickness varies across the width of the web arrives, the upper calibrating roller is installed parallel to the surface of the web. For this turn

the steering wheel 23 moves the screw 22 and the slider 18 connected to it with the pins l4 of the upper gauge roller 10. The cylindrical insert 1b rotates inside the cylindrical groove of the slide 18, thereby preventing the upper gauge roller from bending 10. The rotary insert rotates the required angle around The axis passing through the cylindrical liner 1b of the opposite support 15. When processing the web, the thickness of which increases towards the drive end of the upper sizing roller 10, the screw 22 is tightened inside b support 15. When the thickness of the blade is changed in the opposite direction, the screw is reversed.

After the calibration roller 10 is installed parallel to the material web, the thickness of the coating layer is adjusted by turning the roller 10 around an axis. An additional coating layer is applied with a greasing roller.

The proposed device allows to simplify the control of the application of the coating layer, improve the control accuracy and increase productivity.

The invention The apparatus for coating a coiled material comprising a bath for a covering mass, a guide roll, a scraper and a coating layer calibration and calibration mechanism consisting of a support and mounted on an immersion rotary frame that calibrates (pins with pins, the knot for adjusting the gap between the upper calibrating roller and the web of the material being processed, the knot for adjusting the uniformity of the application of the coating layer across the width of the web, in order to ensure ease of maintenance and by simplifying the adjustment of the thickness of the coating layer and increasing productivity by reducing the number of web breaks, the gap adjustment unit is designed as a worm gear, a worm wheel is attached to the end of the axle of the upper sizing roller, installed with eccentricity, and the uniformity of application right layer is made
