Problems solved by technology

In the production device for dry winding prepreg reinforced fiber bundles, a first pressure wheel is installed inside the resin tank, and a hot pressure wheel is installed on the upper right of the first pressure wheel, so that under the action of the first pressure wheel, the The fiber bundle is completely infiltrated by the resin, and then further infiltrated by the hot press wheel, which facilitates precise control of the resin content and improves the production efficiency of the fiber bundle.” When the production device is processing prepreg, it is impossible to adjust the prepreg resin glue penetration content, it is difficult to guarantee the quality of prepreg, and it is easy to cause solvent waste and pollution

Embodiment 1

[0052] see figure 1 and image 3 , an embodiment provided by the present invention: a dry-process winding prepreg preparation equipment, including a vertical board 1, creel rods 102 are installed on the surfaces of the vertical boards 1 close to each other, and the bottom of the vertical board 1 is installed There is a base plate, and a water bath cylinder 6 is installed on the top of the base plate;

[0053] Specifically, the contact area between the manufacturing equipment and the installation surface can be increased through the bottom plate, thereby increasing the installation stability of the manufacturing equipment, and an electric heating tube is arranged inside the water bath cylinder 6, which can clean the inside of the dipping tank 2 placed therein. Carrying out heating treatment in a water bath, thereby ensuring uniform heating treatment of the resin glue liquid inside the dipping tank 2;

[0054] The top of the base plate is equipped with a support, and the suppo...

Embodiment 2

[0058] see figure 2 , an embodiment provided by the present invention: a dry-process winding prepreg preparation equipment, including a lift adjustment rod 7, the top side frame of the dipping tank 2 is equipped with a lift adjustment rod 7 arranged front and rear, the Crosspieces 704 are installed on the surfaces of the lifting adjustment rods 7 that are close to each other, and No. 2 stay rope 703 is installed on the rear surface of the crosspiece 704. An electronic tension gauge 702 is installed on one end of the No. 2 stay rope 703. One end of the electronic tension gauge 702 is installed with a No. 1 stay rope 701 , and the tail end of the No. 1 stay rope 701 is connected with the surface of the creel bar 102 .

[0059] Specifically, when tension needs to be applied to the fiber after yarn threading, the height of the lifting adjustment rod 7 can be adjusted, and then the crosspiece 704 is driven to rise synchronously. The tension effect is formed between the No. 2 stay...

Abstract

The invention discloses dry-method winding prepreg filament preparation equipment and a preparation process thereof. Vertical plates are included, creel rods are installed on the surfaces, close to each other, of the vertical plates, a bottom plate is installed at the bottoms of the vertical plates, a water bath tank is installed at the top of the bottom plate, and a glue dipping tank is placed in the water bath tank and located on one side of the vertical plates. Lifting adjusting rods which are arranged front and back are installed on a frame on one side of the top of the glue dipping tank, supporting frames are installed on frames on the front face and the back face of the top of the glue dipping tank, a support is installed on the top of the bottom plate and located on one side of the glue dipping tank, and a detection platform is installed on the top of the support. Epoxy resin and a curing agent are mixed to prepare a resin glue solution, then fibers sequentially pass through the creel rods, the glue dipping tank, the detection platform and a winding rod to complete preparation of prepreg filaments, and the method for preparing the prepreg filaments is low in cost, high in production speed, free of solvent pollution and suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of prepreg, in particular to a dry winding prepreg preparation equipment and a preparation process thereof. Background technique [0002] Dry winding refers to the use of prepreg tape / filament to be directly wound on the mandrel, without involving the dipping process, and has the advantages of controllable resin content, high production efficiency, and environmental friendliness. At present, dry winding prepreg tape / filament preparation Mainly include: solution impregnation method, hot-melt impregnation method, powder process method, solution impregnation method uses solvent in the preparation process, needs high-temperature drying and causes environmental pollution; hot-melt impregnation method needs to melt the resin and use release paper to seal the prepreg wire Isolation, and then slitting to form a prepreg tape, the process is cumbersome and damages the fibers; powder process method to prepare resin pow...
