Direct-combustion compression production process for waveform asphalt shingle

Abstract

The invention relates to a waveform asphalt shingle direct-fired compression production process, and belongs to the technical field of paperboard drying and forming. The process mainly comprises the following steps: paper feeding, plate preheating, extrusion forming, drying forming and fixed-length cutting, namely a roll paper material is placed on the feeding device, the roll paper material passes through a guide frame, the angle of the roll paper material is corrected, and then a wet paper plate extends towards the preheating device; the pre-heating device penetrates through a space between an upper pre-heating plate and a lower pre-heating plate of the pre-heating device to pre-heat the paperboard initially; the paperboard subjected to initial preheating enters an extrusion forming device, and the paperboard is subjected to extrusion forming through an upper pressing roller and a lower pressing roller; the paperboard is guided to enter the drying and forming device above, and the extruded and formed paperboard is dried and heated again through hot steel pipes uniformly distributed on the drying and forming device so as to be used for finally drying moisture and keeping the shape of the paperboard; and under the control of the PLC control system, the paperboards passing through the drying and forming device are cut off in a fixed-length mode through the cut-off press machine.

Description

technical field [0001] The invention relates to a corrugated asphalt shingle direct-combustion compression type production process, which belongs to the technical field of cardboard drying and forming. [0002] technical background [0003] Corrugated asphalt waterproof tile is made of high-quality single-layer thick mineral plant fiber board, impregnated with asphalt under high temperature and high pressure. Since it is formed at high temperature, it has high compressive strength and excellent waterproof performance, and has a long service life. [0004] Because the permeable roof structure formed by using this material is very simple, it is also easy to cooperate with other insulation materials and roof tiles, which not only reduces the total cost of the roof project, but also makes the construction easier, so the quality of the roof project is better. guaranteed. [0005] There are big problems in the corrugated asphalt waterproof tile pressing and drying production equi...
