Cloth feeding and dipping device on hollow composite slab production line

Abstract

The invention discloses a cloth feeding and dipping device on a hollow composite slab production line. The cloth feeding and dipping device comprises a glue preparing device, a frame platform, a lower film unreeling machine, a glue distribution device, a first dipping roller, a hollow cloth unreeling machine, a multi-reel constant tension active unreeling mechanism, an auxiliary standing device, an upper film unreeling machine and a power thickness controller, wherein the lower film unreeling machine, the glue distribution device, the first dipping roller, the hollow cloth unreeling machine, the multi-reel constant tension active unreeling mechanism, the auxiliary standing device, the upper film unreeling machine and the power thickness controller are orderly arranged along the frame platform; a constant tension controller is arranged on the multi-reel constant tension active unreeling mechanism; the glue preparing device is communicated with the glue distribution device through a hose. By adopting the cloth feeding and dipping device on the hollow composite slab production line disclosed by the invention, the resin dosage and the resin temperature can be accurately adjusted; bubbles generated in the mixing process of the resin and a curing agent are removed; the sizing sufficiency of hollow fabric, the glue content uniformity and the hollow fabric standing property are improved; the planeness and the height dimension of the product are accurately controlled; the cloth feeding and dipping device has the advantages of being low in manufacturing cost, high in production efficiency, stable in product quality and the like; continuous automatic production can be achieved; the marketizing requirements can be met.

Description

technical field [0001] The invention relates to a cloth putting and dipping device on a hollow composite flat plate production line. Background technique [0002] The hollow sandwich composite material component is made of high-performance fiber (high-strength glass fiber, carbon fiber, etc.) woven into a three-dimensional hollow sandwich fabric as a reinforcing material, and compounded with a modified resin. Its overall hollow sandwich structure has excellent mechanical, flame retardant, sound insulation, heat insulation and other characteristics, overcomes the shortcomings of traditional honeycomb, foam and other sandwich composite materials that are easy to delaminate and have poor impact resistance, and is widely used in rail transit car bodies The load-bearing structural parts and auxiliary parts can realize the weight reduction and energy saving of the vehicle and improve the overall performance. [0003] The infiltration process of the existing hollow composite flat ...

AI Technical Summary

Problems solved by technology

[0003] The infiltration process of the existing hollow composite flat panel is mainly hand lay-up process. The laying of the hollow fabric and the resin impregnation are completely dependent on the technical level of the operator. During the operation, inconsistent infiltration speed, uneven resin content, and air bubbles are likely to occur Cannot be completely discharged, the thickness and size of the flat plate cannot be accurately controlled, etc., and the product performance and quality are difficult to control and guarantee

The traditional cloth dipping process has low production efficiency, high manufacturing cost, long production cycle, cannot be continuously automated production, and cannot meet market demand
