In the process of preparing fiber-reinforced resin-based composites by pultrusion, the fibers on the creel are pulled by the haul-off machine, and sequentially pass through the dipping tank for dipping, curing mold curing, and post-curing box for post-curing. Glue dipping in the glue tank is one of the most critical steps in the pultrusion process and one of the decisive factors for the quality of the product.

The dipping machines currently used mainly include single-slot dipping machines and fixed double-slot dipping machines. During the long-term production process, due to the old glue at the bottom of the dipping tank, there will be solidification, crystallization and other phenomena that are not conducive to production and stable product quality. It is necessary to replace the dipping tank in time and repair the old dipping tank. to clean up. The single-tank dipping machine cannot be replaced during the production process, and is not suitable for long-term production. The fixed double-tank dipping machine can replace the dipping tank during the production process, but the dipping tank is fixed in the support body of the dipping machine, which is inconvenient to clean. If the operation is not done properly, the cleaning agent will easily contaminate the fiber.

The concave part of the dipping tank is seated in the support body of the dipping machine. After the position of the dipping tank is determined, the rubber pads, nuts, and bolts pass through the support body of the dipping machine. The guide rail is connected with the support body of the dipping machine, and the dipping tank is fixed in the horizontal direction; the dipping tank has a double-layer structure, the inner layer is a closed tank, and circulating water is passed between the layers, and the outer layer has water inlet holes and The water outlet hole and the corresponding sealing device are connected with the circulating pump and the water tank through a hose. The two dipping tanks can be equipped with separate circulating water pumps. Each circulating pump is equipped with an independent control switch. The two tanks share a cycle. Water tank; each dipping tank is equipped with pressing rollers and squeezing rollers, which are connected to the support body of the dipping machine through bolts and springs; the circulating water tank is equipped with a heating device and a temperature control system.

The beneficial effect of the present invention is that the present invention can avoid the phenomenon that the glue solution at the bottom of the dipping tank reacts and crystallizes but cannot be cleaned in time during the long-term production process, and has the advantages of easy operation, excellent product performance, and stability.

detailed description

As shown in Figures 1-3, the present invention consists of a dipping machine support body 1, a first dipping tank 2, a second dipping tank 3, a first circulation pump 4 and a second circulation pump with independent switches and valves 5. The hose 6, the water tank 7, the heating control system 8, the vertical fixing bolt 9, the horizontal fixing bolt 10, the squeeze roller 11 and the pressing roller 12 are composed.

In the long-term production process, the fiber is first dipped in the first dipping tank 2, and the water tank 7 is passed into the interlayer of the first dipping tank 2 through the first circulating pump 4 and the hose 6. The circulating water is fed by the The heating control system 8 heats up the first dipping tank 2 to the set temperature, and the fiber is pressed into the glue liquid level of the first dipping tank 2 by the rubber pressing roller 12, and then the rubber extrusion roller 11 pairs Glue-impregnated fibers are controlled for glue content. When production takes a long time and semi-solidified, crystallized, and massive objects appear at the bottom of the first dipping tank 2, the dipping tank needs to be replaced. At this time, the second cycle The pump 5 is turned on, and the second dipping tank 3 is preheated. After preheating, the pressing roller 12 and the squeeze roller 11 are installed, and the glue is poured into the second dipping tank 3. After pouring the glue, the The first circulation pump 4 is closed and the hose 6 connected to the first dipping tank 2 is removed, the first dipping tank 2 is removed from the dipping machine support body 1 for cleaning, and after the first dipping tank 2 is disassembled, Disassemble the horizontal fastening bolt 10 and the vertical fastening bolt 9 of the second dipping tank 3, the second dipping tank 3 moves to the position of the first dipping tank 2 under the action of fiber tension, and then tighten the horizontal tightening Fasten the bolt 10 and vertically fasten the bolt 9, and then place the cleaned first dipping tank 2 inside the dipping machine support body 1 from bottom to top to the original position of the second dipping tank 3, pay attention not to hits the traveling fiber. When the second dipping tank 3 needs to be cleaned, repeat the above steps.

example 1:

Taking the production of glass fiber rods with a diameter of 7.5mm and a length of 1000mm by pultrusion as an example, 58 bundles of glass fibers are required for production. In the process of pultrusion, only one dipping tank in the dipping machine is used. When the dipping When there are crystallized, semi-solidified or solidified lumps and viscous objects in the tank, stop the car to clean the dipping tank, continue production according to the operation method in the above embodiment and use another dipping tank of the dipping machine.

Example 2:

Taking the production of glass fiber rods with a diameter of 22.5 mm and a length of 1000 mm by the pultrusion process as an example, 522 bundles of glass fibers are required. During the pultrusion process, two dipping tanks are used at the same time. In the second dipping tank 3 After dipping, second dipping is done in the first dipping tank 2 to ensure sufficient fiber dipping when there are many fiber bundles.

Example 3:

Taking the pultrusion process to produce a carbon fiber mandrel with a diameter of 7.5mm and a length of 100km as an example, 60 bundles of carbon fibers are required, and only one dipping tank in the dipping machine is used during the pultrusion production process. Crystalline, semi-cured or solidified massive, viscous objects continue to be produced according to the operation method in the above-mentioned embodiment and use another dipping tank of the dipping machine.
