Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of composite grid production technology structure, and particularly relates to an automatic yarn winding system for glass fiber reinforced plastic (FRP) molded grid forming. BACKGROUND

[0002] Glass fiber reinforced plastic (FRP) molded grid was invented in the 1940s, and has irreplaceable advantages in preparing various drilling platforms, ship decks, walkways, and insulation equipment due to its light weight, high strength, corrosion resistance, and other characteristics. At present, the glass fiber reinforced plastic (FRP) molded grid series products have been widely used in the fields of petroleum and chemical industry, sea and land transportation, civil construction, and power engineering, and have broad domestic and overseas markets.

[0003] The glass fiber reinforced plastic (FRP) molded grid product is named due to its molding forming process, and the specific process flow can be summarized as follows: fiber laying, resin pouring, compaction and degassing, heating and curing, (cooling), and demolding. In terms of composition, the glass fiber reinforced plastic (FRP) molded grid is a multiphase material formed by taking synthetic resin as a matrix and taking carbon fiber or glass fiber as a reinforcing material; in terms of geometric characteristics, the glass fiber reinforced plastic (FRP) molded grid is a porous rectangular plate. Due to the complexity of the molding forming process itself and the porous characteristics of the grid product, it is difficult to realize the automatic production of the glass fiber reinforced plastic (FRP) molded grid. At present, each production process of the domestic glass fiber reinforced plastic (FRP) molded grid product is manually operated, that is, the bundled fibers are manually laid layer by layer, the liquid resin is manually poured layer by layer, and the product is manually compacted and degassed multiple times. This production method mainly has three problems: first, human operation errors such as fiber missing laying or re-laying and uneven resin pouring can easily occur, which can cause unstable overall product quality; second, the labor intensity is high, the working environment is poor, which can cause fatigue work and occupational diseases; and third, the labor cost is high and the production efficiency is low, which can cause the production capacity to decrease, the economic benefits to decrease, and the large-scale production of the glass fiber reinforced plastic (FRP) molded grid product to be not conducive.

[0004] The existing patent CN201810528877.6 provides a glass fiber reinforced plastic molding grid automatic yarn winding system, which comprises a base support, and a forming mold is arranged on the base support; longitudinal yarn winding slides and transverse yarn winding slides extending along the length direction of the forming mold and the width direction of the forming mold are respectively arranged on the base support on both sides or both ends of the forming mold, a longitudinal yarn winding car is arranged on the longitudinal yarn winding slide, and a transverse yarn winding car is arranged on the transverse yarn winding slide; a longitudinal yarn clamping and cutting device extending along the width direction of the forming mold is fixedly connected to the inner side of the base support between the longitudinal yarn winding car and the forming mold, and a transverse yarn clamping and cutting device extending along the length direction of the forming mold is fixedly connected to the inner side of the base support between the transverse yarn winding car and the forming mold; and the longitudinal yarn winding slide and the transverse yarn winding slide each comprise a roller type slide and a group of cylindrical linear guide pairs. The advantages of the present application are that the phenomenon of wheel rolling yarn can be effectively avoided by the system.

[0005] However, the above-mentioned patent still has the following defects: the longitudinal and transverse yarns in the forming mold are both made of a single glass fiber yarn, which leads to the fact that when the glue is injected into the grid forming cavity of the forming mold, the glass fiber yarn at the corner of the grid forming cavity is easily scattered or deviated by the resin, and finally the structural strength of the molded glass fiber reinforced plastic molding grid is reduced.
