Description

Technical Field

[0001] This utility model belongs to the field of carbon fiber wet winding technology, and more specifically, it relates to a fiber impregnation device for wet winding. Background Technology

[0002] When processing carbon fiber composite high-pressure gas cylinders, it is mostly necessary to wind carbon fiber bundles onto a mandrel by wet winding. During winding, the carbon fiber bundles need to be passed around the tension rod and then inserted into the impregnation box. At this time, the resin will penetrate into the fiber bundle through capillary action. After the fiber is fully impregnated with resin, it is wound onto the mandrel according to the predetermined winding pattern. After curing, a composite high-pressure gas cylinder with specific properties is formed.

[0003] Based on the above, during the impregnation process of carbon fiber bundles, the resin penetration rate of the bonded fibers is relatively slow, which affects the impregnation efficiency of the carbon fiber bundles and consequently affects the production efficiency of carbon fiber composite high-pressure gas cylinders. Utility Model Content

[0005] The purpose and effectiveness of this utility model for a fiber impregnation device used in wet winding are achieved by the following specific technical means:

[0008] Furthermore, the extrusion structure also includes a lower extrusion roller and an upper extrusion roller; the lower extrusion roller is rotatably connected to the upper part of the impregnation box body; the upper extrusion roller is rotatably connected to the inner side of the two guide connecting blocks.

[0009] Furthermore, the extrusion structure also includes a carbon fiber guide ring and a position adjustment screw; the carbon fiber guide ring is fixedly connected to the right side of the impregnation box body; there are two position adjustment screws, which are rotatably connected to the outside of the two guide mounting plates respectively, and the two position adjustment screws are threadedly connected to the two guide connecting blocks respectively.

[0010] Furthermore, the transmission structure includes carbon fiber tensioning rods, a synchronous transmission structure, and incomplete drive gears; multiple slots are provided on both the front and rear sides of the guide mounting frame, and multiple carbon fiber tensioning rods are provided, each passing through a slot and then fixedly connected to the upper part of the guide mounting frame by bolts; the synchronous transmission structure is a synchronous belt transmission mechanism, and two synchronous transmission structures are provided, with the carbon fiber unwinding roller and the limiting transmission shaft being connected by the two synchronous transmission structures; two incomplete drive gears are provided, and the two incomplete drive gears are respectively fixedly connected to the front and rear sides of the limiting transmission shaft.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention uses a carbon fiber combing plate to separate the bonded fibers in the carbon fiber bundle, increasing the resin penetration rate and thus improving the impregnation efficiency of the carbon fiber bundle. This enhances the production efficiency of carbon fiber composite high-pressure gas cylinders. Simultaneously, the oscillating motion of the carbon fiber combing plate agitates the resin, ensuring its uniform composition and good flowability, guaranteeing effective impregnation of the carbon fiber bundle. Excess resin is extruded from the carbon fiber bundle using lower and upper extrusion rollers, controlling the resin content and ensuring the impregnated fiber bundle has a suitable resin content. This guarantees the production quality of the carbon fiber composite high-pressure gas cylinder and prevents resin waste caused by the carbon fiber bundle carrying resin with it after leaving the impregnation box.
