Background

The pultrusion process is a production process with higher automation degree in the production process of the fiber composite material. Specifically, pultrusion refers to a process of forming a linear product of a composite material by dipping, extrusion molding, heating and curing, and fixed-length cutting a prepreg tape, a fiber or a fabric and the like under the traction of an external force. The process is suitable for producing composite material section bars with various section shapes, such as bars, pipes, solid section bars, cavity section bars and the like. However, the fibers tend to absorb moisture from the air, resulting in increased fiber moisture content, which can affect the performance of the composite material. For example, when the impregnation process is performed, the contact surface between the fibers and the resin is reduced due to excessively high water content in the fibers, which affects the processing effect of the impregnation process and reduces the quality of the finished composite material.

In the prior art, before the impregnation process, the fiber is put into an oven, and the fiber is dried by the oven.

As shown in fig. 2, 4 and 12, the upper frame 23 further includes at least two upper substrates 231, each upper substrate 231 is connected by an upper roller 22, the lower frame 33 includes at least two lower substrates 331, and each lower substrate 331 is connected by a lower roller 32. The upper substrate 231 is connected to the upper roller 22 by a bearing, for example, and the lower substrate 331 is connected to the lower roller 32 by a bearing, for example.

When the number of the upper substrates 231 and the number of the lower substrates 331 are two, the two upper substrates 231 are connected by the upper rollers 22, the two lower substrates 331 are connected by the lower rollers 32, the upper driving belt is sleeved between the two upper substrates 231 on the plurality of upper rollers 22, and the lower driving belt is sleeved between the two lower substrates 331 on the plurality of lower rollers 32. When the number of the upper substrates 231 is more than two, each upper roller 22 passes through the plurality of upper substrates 231, the upper transmission belts are sleeved between the adjacent substrates on the plurality of upper rollers 22, and the number of the upper transmission belts 21 is one less than that of the upper substrates 231. When the number of the lower substrates 331 is more than two, each lower roller 32 passes through the plurality of lower substrates 331, the lower conveyer belt is sleeved between the adjacent substrates on the plurality of lower rollers 32, and the number of the lower conveyer belts 31 is one less than that of the lower substrates 331.
