Fiber fabric extraction box for glass fiber reinforced plastic hand lay-up molding

Abstract

The invention relates to the technical field of glass fiber reinforced plastic production, in particular to a fiber fabric extraction box for glass fiber reinforced plastic hand lay-up molding. The fiber fabric extraction box comprises a box body provided with a handle, the box body is provided with a bottom cover, a discharging notch with a scraper is formed in the upper portion of the box body, a cutting device is arranged above the discharging notch, a rotating shaft with a clamping mechanism is arranged inside the box body, and a rotating device is connected to an end of the rotating shaft; and a sealing ring is arranged between the rotating shaft and the box body. According to the fiber fabric extraction box, smell emission of a resin mixture is effectively reduced, glass fiber filaments are prevented from flying into the environment, and human health is guaranteed; resin mixture coating and fiber fabric cutting procedures can be continuously carried out, and the working efficiency is improved; the device is compact and closed in structure and convenient to carry for operation; the fusion degree of glass fiber fabric and the resin mixture is improved, and multiple layers of fiber fabric with the resin mixture can be prepared simultaneously; and in addition, the thickness of a glass fiber reinforced plastic product can be accurately controlled, and the surface flatness of the glass fiber reinforced plastic product can be improved.

Description

technical field [0001] The invention relates to the technical field of FRP production, in particular to a fiber fabric extraction box for FRP hand lay-up. Background technique [0002] The hand lay-up molding process of FRP is also called the contact molding process. It is a process of laying the cut glass fiber fabric and resin mixture alternately on the mold or existing FRP products by hand, and then solidifying and forming. The process is simple and easy to master, the equipment is simple, and the personnel only need short-term training. in production. The product forming of this process is not limited by size and shape, and is suitable for the production of FRP products of various sizes, small batches, and complex shapes. Reinforcing materials can be added to different parts of the product at will. The resin content of the product is high, so the corrosion resistance is good. [0003] However, this process has the following disadvantages: 1: The mixed resin is prepared...

Problems solved by technology

[0003] But this process has the following disadvantages: 1: The mixed resin is prepared in an open and exposed environment, which has a strong chemical smell and is easy to mix in various impurities in the environment , it is easy to cause damage to the respiratory tract and eyes of construction workers and reduce the quality of the mixture; 2: The traditional process of mixing the mixture and preparing the fiber fabric is inconvenient to operate, mass production requires a lot of manpower, and the product output is difficult to increase; 3: Traditional modulation The container of the mixture is often simple and bulky, which is inconvenient to carry for high places or narrow space operations, which affects the construction efficiency; 4: The glass fiber fabric is exposed to the environment for a long time, and the fiber filaments are easy to fly into the air during the process of carrying and construction Then it is inhaled by the human body, causing damage to the health of personnel; 5: The process of painting the mixture first and then laying the fiber fabric will easily cause the two to not fully integrate and the amount of the mixture is not easy to control, resulting in products that are too thick or too thin, affecting FRP products 6: In order to fully integrate each layer of resin mixture and fiber fabric, it can only be laid layer by layer, the production speed is slow and the efficiency is low; 7: The material waste rate is high
