Glue squeezing device for producing three-dimensional fiber reinforced composite materials

Abstract

The invention provides a glue squeezing device for producing three-dimensional fiber reinforced composite materials. The glue squeezing device comprises a glue discharging plate (1), a feeding support plate (3), a receiving support plate (10), a support (11), an upper roller (12), a lower roller (13), a screw (18), a synchronous transmission mechanism and the like, wherein the position of the lower roller (13) is fixed, the rotation of the screw (18) drives a movable plate (17) to move so as to allow the upper roller (12) connected with the movable plate (17) to move up and down, the upper roller (12) moves a tensioning synchronous pulley support (25) along a support slide rail (26) after being adjusted in position so as to constantly keep the tensioned state of a synchronous pulley (23). The glue squeezing device has the advantages that quantified control and adjustment of the glue content of the composite materials are achieved, the glue content evenness of a single piece of material and the glue content consistency of same-batch materials are increased, production efficiency is increased, and resin glue can be recycled.

Description

Technical field [0001] The invention relates to a rubber extrusion device for preparing composite materials. Background technique [0002] Composite materials have developed into one of the four material systems juxtaposed with metallic materials, inorganic non-metallic materials, and polymer materials. Three-dimensional fiber-reinforced composite material refers to a composite material with three-dimensional fibers interwoven in space to form a non-layered overall structure as a reinforcement, and a resin as a matrix solidification molding. It has light weight, high specific strength, corrosion resistance, and good dimensional stability. It has excellent comprehensive characteristics such as a set of warp yarn connections in the thickness direction, which overcomes the fatal weakness of laminate composite materials and honeycomb sandwich composite materials that are easy to delamination. It has good interlayer performance and impact resistance, and is obtained in various fields ...

AI Technical Summary

Problems solved by technology

[0005] (2) The uniformity of the rubber content inside the single material is poor, which is difficult to quantify

On the one hand, the same operator does not control the strength consistently when extruding glue with both hands, resulting in uneven distribution of resin solution in different parts of the single material; The flow from bottom to bottom causes the content of the lower part to be higher than that of the upper part. Although the process is repeated by turning 180 degrees, the unevenness still exists.

[0006] (3) The consistency of the glue content between the same batch of composite materials is poor, and it is difficult to control

On the one hand, as the operation time increases, the operator’s arm fatigue will cause inconsistent force control between batches when extruding the rubber; on the other hand, the resin content of the materials prepared by different extruding operators is inconsistent

[0007] However, the existing mechanical device with upper and lower rollers cannot meet the process requirements, and the main disadvantages are:

[0008] (1) The distance between the upper and lower rollers cannot be adjusted freely according to the needs, and the quantitative control and adjustment of the glue content of the composite material cannot be realized, nor can it adapt to the needs of products with different thicknesses

[0009] (2) The rotation direction of the upper and lower rollers is single, and it is impossible to rotate clockwise or counterclockwise according to the needs, and it is impossible to realize multiple rapid extrusion of the product, and the efficiency is low

[0010] (3) There is no excess glue collection and reuse system, the waste of resin glue is serious, polluting the production site, and increasing production costs
