Sand spraying device for manufacturing camouflage roofing shingles

Abstract

The invention provides a sand spraying device for manufacturing camouflage roofing shingles. A plurality of dosing sand hoppers capable of automatically controlling sand spraying, a guide sand hopper and a main sand hopper are arranged on a sand spraying section of a roofing shingle production line; a gradual change colored sand layer with a light color, an intermediate color and a deep color is sprayed on a substrate surface by controlling the opening, running, rotating speed and stopping time of a rolling gate at a sand outlet and sand spraying quantity and sand spraying sequence, and is pressed with a glass fiber substrate cloth to which molten heated asphalt is applied so as to obtain the camouflage roofing shingles; the sand outlets of the dosing sand hopper and the main hopper are provided with plug-board sand flashboards; and a roller gate driven by an adjustable-speed motor is arranged below the sand outlet and is controlled by a controller with a preset program. The camouflage roofing shingles manufactured by using the device have gradually changing camouflage surface effect and a camouflage roofing shingle product has rich layer effect and sense of rhythm. Buildings on which the camouflage roofing shingle products are laid have the characteristics of vividness and magnificence. Therefore, a condition for beautifying the fifth side of buildings in cities and towns is created.

Description

technical field [0001] The invention relates to the technical field of making waterproof materials for roofs, in particular to a sand spreading device for making camouflage colored asphalt tiles whose surface color changes gradually. Background technique [0002] It has been some years since the roof waterproofing material has transitioned from the "Qin brick and Han tile" that lasted for two thousand years to cement tiles, glazed tiles, and ceramic tiles. The advent of roof waterproofing "coils" has entered a new stage in the field of roof waterproofing technology. In recent years, the colored linoleum tiles belonging to waterproof membranes have added brilliant colors to the roofs of modern buildings. Villas, playgrounds and park buildings, multi-storey or small high-rise residential buildings paved with colored linoleum tiles made of colored sand, asphalt and glass fiber non-woven fabric base have become a bright spot in thousands of small towns in the city. Landscape. ...

Problems solved by technology

But as far as the current situation is concerned, there is no such production process and device that can do it, so it is necessary to completely reform the sand spreading device in the existing sand spreading section.
