Description

The invention relates to the construction, in particular, to machines for sticking rolled roofing materials for the production of roofing works.

The purpose of the invention is to improve the quality of the sticker, reduce energy consumption and increase productivity.

The goal is achieved in that a device for gluing rolled roofing materials with an adhesive layer, comprising a trolley with a pressure roller mounted on the frame, on the axis of which a housing with a multi-colored high-resistance precision alloy alloy radiator is mounted according to the invention is equipped with thermo-radiation

screens placed between the housing and the radiator, which is made in a semi-cylindrical shape with a radius of curvature of 60-200 mm and is fixed with the orientation of the radiation indicatrix in the contact zone of the pressure roller, the shape of the thermo-radiation screens corresponding to the shape of the radiator. In addition, thermo-radiation screens are made in the form of heat-resistant metal sheets installed in steps and interconnected along the contour.

In FIG. 1 shows a device for gluing roll roofing materials with an adhesive layer, general view; FIG. 2 - node I in FIG. 1; FIG. 3 is a diagram of an infrared emitter.

The device for gluing rolled roofing materials with an adhesive layer includes a self-propelled carriage 1 with support wheels 2, a pressure roller 3 and a frame 4 articulated with it, on which an infrared emitter 5 is mounted by means of a lever 6. The infrared emitter consists of a glow element - shell 7, formed from tapes of precision alloys with high electrical resistance with a concave semi-cylindrical surface (radius of curvature 60-200 cm), coaxially mounted to the shell of thermo-radiation screens 8 and the body 9, the shield is provided with a drive 10. The trolley 11 and puskoregulirovochnoy apparatus 12. The web material roll 13 under roller mill m 3, cover them emitter 5.

The device operates as follows.

With the lever 6, the emitter 5 is moved away from the roller 3, between the emitter and the roller and under the roller the end of the web of the pre-rolled roll is wound, then the emitter and the movement of the device are sequentially turned on. The speed of the device is controlled depending on the intensity of the occurrence of the bitumen melt at the edge of the glued web, while with an optimal emitter power of 25-30 kW, the speed of movement is 200-300 m / h. As the device approaches the end of the glued web, the emitter is first turned off, then the speed of movement is uniformly reduced and completely turned off at the end of the web, then the cycle repeats.

During operation, the radiating shell of the filament element is heated to the maximum allowable temperature of 1100-1150 ° C, which, along with the concentration due to the semicylindrical shape of the filament element and the increase in its density by the action of thermo-radiation screens, provides an irradiation density of the adhesive layer of the material within 12-18 W / cm2, which results in high productivity and insignificant heat losses, which are known to be inversely proportional to the radiation density. Thermo-radiation screens sharply reduce the flow

radiation in the direction of the casing, which eliminates overheating of the adhesive layer of material on its surface and has a beneficial effect on the quality of the sticker.

Thermal radiation screens installed in increments are concave metal sheets of a heat-resistant alloy, for example nichrome, interconnected along a contour. The number of screens ranges from one to five, as the design becomes more complex with increasing number, and efficiency increases slightly. When heated, the screens themselves become emitters and form

a powerful stream of return radiation and at the same time attenuate radiation to the side behind the screens by a factor of n +1, where n is the number of screens. The radius of curvature of the sheath-element of the filament is optimally 60-200 mm,

for an increase in the radius entails an increase in the degree of scattering, underheating of the glued layers and a decrease in productivity, and a decrease in the radius of curvature increases the degree of return radiation, which negatively affects the service life of the cladding element.
