Abstract

A pultrusion mechanism for pultruding a fiber sheet includes a squeezing-flattening mechanism provided between a heat curing mold and a main holding mold, wherein the squeezing-flattening mechanism includes a plurality of squeezing roller assemblies, each of which includes a convex roller and a concave roller. Axes of the convex roller and the concave roller are parallel, and an arc gap is left therebetween. The arc gap allows a planar fiber sheet to pass through, squeezed into an arc. The convex rollers and the concave rollers of the multiple squeezing roller assemblies are alternatively arranged in a staggered manner, bending the fiber sheet upward and downward within a tolerable scope of flexible deformation. In other words, by bending upward and downward the fiber sheet, internal stress of the fiber sheet can be eliminated before it is fully cured.

Description

Pultrusion forming mechanism of pultruded fiber sheet

The invention relates to a forming technology of pultruded fiber boards, in particular to a pultrusion forming mechanism of pultruded fiber boards for shaping the formed boards to eliminate internal stress.

Press, when pultrusion produces fiber boards, the fibers are impregnated from the resin tank and enter the mold. After being heated and solidified by the mold, the cured board is pulled out of the mold through pultrusion, and then the board is rolled up by the winding rack, but the above-mentioned It is not difficult to find that there are some deficiencies in the conventional structure. The main reasons are: (1) The forming mold continuously heats and solidifies the plate, and continuously forms a continuous fiber plate by pultrusion, so the plate is formed in the forming mold. Insufficient heating time in the interior leads to incomplete curing of the inside of the board, and the incompletely cured board will form a high internal stress inside, although there will be no bending of the board because it has been rolled tightly during winding, However, after the sheet is pulled out during use, the internal stress of the sheet will be released, causing the sheet to be deformed to bend up or down on both sides. On the contrary, if it is heated in a forming mold and waits for complete curing, it will be difficult. The disadvantage of the pultrusion extraction molding die is that excessive pultrusion force will cause tensile deformation of the sheet, and it is not a method to overcome the internal stress caused by insufficient curing; (2) The fiber yarn is multi-column yarn rolls before impregnation Put it on the frame, and then pull it from a large area to a small area to form a yarn bundle, and then pass the yarn bundle through the resin tank for impregnation. The amount of resin is insufficient, and because of the difference in pulling angle and distance, the distribution of yarn bundles will be uneven, and it is not easy to form a straight line. When entering the narrow mold yarn inlet in a not completely straight line, the outer edge The yarn will be easily worn to form an oblique shape or be torn off. The oblique yarn bundle will increase the internal stress of the formed sheet. When the pultrusion fiber sheet is unfolded, the sheet will bend, and the torn yarn will The thread will reduce the structural strength of the formed sheet; (3), the conventionally used clamping mold is driven by a hydraulic cylinder, and after the effective pultrusion stroke, the fiber sheet will be released for the return stroke. At this time, the continuous pulling of the fiber sheet forms a Short stagnation, this situation will not only make the heating time of the fiberboard uneven, but also form an excessive pultrusion force between pulling and stopping, resulting in an increase in the internal stress of the fiberboard, which will affect the production quality of the fiberboard. If two sets of clamping molds are directly installed, the construction cost will be too high, and the parallel two sets of clamping molds will also greatly extend the production line.
