Embodiment Construction
[0044] As shown in the figure, a production process of double-layer butt-joint polygonal three-dimensional structural panels includes the following steps:
[0045]First, mix the resin, filler and other functional additives according to a certain ratio, and then put them into the hopper of extruder A, and produce two preformed sheets through extruder A.
[0046] Then two pre-formed sheets are introduced into the crawler-type forming device C; specifically, the two pre-formed sheets are respectively attracted and attached to the inner surfaces of a pair of oppositely arranged forming steel belts 3, the forming steel belts 3 Both ends are driven by transmission rollers, the surface of the forming steel belt 3 is regularly inlaid with punches 13, and the bottom surface of the forming steel belt 3 is provided with pinholes 14 communicating with the negative pressure space.
[0047] In production, when the vacuum pump is working, negative pressure is generated, so that the negative ...

The invention discloses a double-layer-butt-joint multi-edge three-dimensional structural slab production technology, a continuous production forming device and a structural slab. The production technology includes the steps that two pre-formed sheets are led into the crawler-type forming device and sucked and attached to the surfaces of the inner sides of a pair of oppositely-arranged forming steel belts respectively, the two ends of the forming steel belts are driven through transmission rollers for transmission, male dies are regularly embedded into the surfaces of the forming steel belts, and needle holes communicated with negative pressure space are formed in the bottom faces of the forming steel belts. According to the double-layer-butt-joint multi-edge three-dimensional structural slab production technology, the continuous production forming device and the structural slab, multi-edge three-dimensional protrusion parts are formed with a male-die vacuum plastic sucking method, the flat bottoms of the protrusion parts made with the method are located at the upper portions of the dies, the surfaces of the sheets are located at the bottoms of the dies, the flat bottoms of the sheets are not stretched, materials on the upper surfaces and the side walls are stretched by large vacuum plastic suction area, the thickness of the side walls of the made protrusion parts is good in evenness, and therefore the overall bending strength of the protrusion parts is high.
Description
technical field [0001] The invention relates to a production process of double-layer butt joint multilateral three-dimensional structural panels, continuous production molding equipment and structural panels. Background technique [0002] At present, the double-layer structure board is made of two pre-formed sheets through vacuum molding to form a multilateral three-dimensional structure skeleton, and then the two structural skeletons are bottom-to-bottom thermocompression bonded to form a double-layer docking multilateral three-dimensional structure board products. [0003] However, the traditional vacuum-absorbing production method mostly adopts the die vacuum-absorbing method. The process is that the material at the entrance of the die is stretched and adsorbed on the side wall and bottom of the die to form a three-dimensional skeleton. Due to the small area at the entrance of the die, the wall thickness of the three-dimensional skeleton made after blistering is relative...
