Manufacturing method and equipment for glass fiber-reinforced plastic grid

Abstract

The invention provides a manufacturing method and equipment for a glass fiber-reinforced plastic grid. The manufacturing equipment comprises a grid manufacturing mold, elastic support legs, a vibration motor, an industrial personal computer, a driving device, and a flattening and yarn drawing assembly. The driving device is arranged, a transmission motor drives a sliding table to move linearly through a lead screw, and in combination with the work of a linear module, the flattening and yarn drawing assembly can realize the functions of flattening resin on the grid manufacturing mold in a scraping mode and drawing warps and wefts, so that labor intensity is effectively lowered, and the number of needed workers is reduced. A yarn drawing toothed plate is arranged and can be used for carryingout yarn drawing on the resin and glass fibers, so that the seeping effect of the resin and glass fibers is improved. A scraping plate is arranged and can flatten the resin on the grid manufacturingmold in a scraping mode and scrap the resin into warp and weft grooves. The elastic support legs and the vibration motor are arranged, when the vibrator motor vibrates, the grid manufacturing mold hasa good vibration effect, the resin can be fully mixed and seeped into the glass fibers, and the overall quality of the glass fiber-reinforced plastic grid is improved.

Description

technical field [0001] The invention belongs to the technical field of FRP grid production, and in particular relates to a method and equipment for manufacturing a FRP grid. Background technique [0002] FRP (referred to as FRP) grating, also known as FRP grating, is a kind of plate-shaped material with many spaces that is made of glass fiber as a reinforcing material, unsaturated polyester resin as a matrix, and compounded through special processing. FRP grating can be used as a structural material for floors in corrosive environments, trench covers, platforms, ship decks, stairs, plank roads, etc. It has the characteristics of corrosion resistance and flame retardant, non-magnetic insulation, bright colors, and various styles and forms for selection. [0003] The existing FRP grating is produced by pouring the resin on the mold, and then the worker holds the scraper to smooth the resin, and manually holds the comb to pull the warp and weft grooves. This process requires t...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a method and equipment for manufacturing FRP grids, so as to solve the problem that the existing FRP grids are produced by pouring resin on the mold, and then the workers hold the scraper to scrape the resin. Hand-held combs are used to pull the warp and weft grooves. This process requires two people to work at the same time. The labor intensity is high, the production efficiency is low, and the impregnation effect of resin and glass fiber is poor, and the quality of the produced FRP grating is unqualified. question
