Description
Technical Field
The invention relates to the technical field of composite sheet manufacturing equipment, in particular to wide-width fiber net reinforced plastic laminated composite sheet manufacturing equipment.
Background
At present, thermoplastic continuous glass fiber reinforced polyethylene sheets produced at home and abroad are called thermoplastic glass fiber tapes (or sheets), the width specification of the thermoplastic glass fiber tapes is generally between 500 millimeters and 1000 millimeters, and the thermoplastic glass fiber tapes are called narrow thermoplastic glass fiber tapes. The width of the thermoplastic glass fiber tape with the common specification is about 600 mm, and the thickness of the manufactured thermoplastic glass fiber tape is between 0.15 mm and 0.4 mm according to the different diameters of the glass fibers. The sheet is mainly used for manufacturing fiber reinforced plastic pipes, and the width of the sheet is cut into narrower (generally 50-160 mm) thermoplastic glass fiber belts for use. The unidirectional thermoplastic glass fiber tape is characterized in that continuous glass fibers are uniformly and parallelly distributed in the length direction, the angle between the continuous glass fibers and the length direction of the longitudinal tape is zero, the unidirectional thermoplastic glass fiber tape is called as the zero-degree glass fiber tape, only bears longitudinal tension and does not bear transverse tension, and the unidirectional thermoplastic glass fiber tape is mainly applied to manufacturing of spiral forward and reverse winding polyethylene reinforced pressure pipelines.
Fig. 1 shows a common fiber reinforced plastic pipe, which includes an inner pipe 01, a glass fiber reinforced layer 02 coated outside the inner pipe 01, and a plastic layer 03 coated outside the glass fiber reinforced layer 02. The glass fiber reinforced layer is formed by winding a plurality of layers of zero-temperature glass fiber belts on the outer side of the inner tube 01 in a positive and negative staggered manner until the target thickness is reached, so that the requirement on the compression resistance of the pipeline is met.
The traditional production mode is that after the inner tube 01 is produced, cut zero-degree glass fiber tapes are used, multiple layers are spirally and reversely staggered and wound on the outer side of the inner tube 01 along the axial direction of the inner tube 01, and the multiple layers of thermoplastic glass fiber tapes are tightly fused together by heating and melting during winding, so that the thermoplastic glass fiber reinforced layer 02 is formed. The traditional production mode is only suitable for producing the fiber reinforced plastic pipeline with small pipe diameter (the inner diameter of the inner pipe is generally 20-630 mm), and if the fiber reinforced plastic pipeline with large diameter (the inner diameter of the inner pipe is 1000 plus 6000mm), the single-piece spiral positive and negative winding mode has low efficiency and large energy consumption, and the fiber reinforced plastic pipeline with large diameter and a bell and spigot can not be produced.
The inventor provides a wide fiber mesh reinforced plastic composite sheet (refer to fig. 2) with lateral sides only containing transverse continuous fibers through research, changes the winding mode of the sheet on an inner pipe, improves the efficiency of producing large-caliber fiber reinforced plastic pipelines in a segmented mode by more than 10 times, reduces energy consumption by several times, can produce fiber reinforced plastic pipelines with flaring openings because the lateral sides only contain the transverse continuous fibers and do not contain longitudinal continuous fibers, and further enables the rapid production of manufacturing the large-caliber fiber reinforced plastic pipelines in a segmented mode to be possible.
The invention aims to provide a device for producing the wide-width fiber net reinforced plastic composite sheet. The composite sheet material manufactured by the equipment can be widely applied to the manufacture of large-caliber thermoplastic fiber net reinforced plastic water supply pipes and other thermoplastic fiber reinforced plastic product industries.
