Description

Technical Field

[0002] Carbon fiber refers to a special fiber composed of carbon elements with a carbon content of more than 90%. Its high-temperature resistance ranks first among all chemical fibers. It is made from acrylic fiber and viscose fiber as raw materials through high-temperature oxidation and carbonization. It is an excellent material for manufacturing high-tech equipment such as aerospace. It has the characteristics of high temperature resistance, anti-friction, electrical conductivity, thermal conductivity, and corrosion resistance. Its shape is fibrous, soft, and can be processed into various fabrics. Due to the preferential orientation of its graphite microcrystal structure along the fiber axis, it has high strength and modulus along the fiber axis direction. The density of carbon fiber is small, so its specific strength and specific modulus are high. The main use of carbon fiber is as a reinforcing material to be compounded with resins, metals, ceramics, and carbon to manufacture advanced composite materials. The specific strength and specific modulus of carbon fiber-reinforced epoxy resin composite materials are the highest among existing engineering materials.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Such as Figure 1 , Figure 2 , Figure 3 andFigure 4 As shown in the figure, the present utility model provides a technical solution for a winding device of a carbon fiber special-shaped pipe, including an equipment frame body 1. A positioning support foot 4 is fixedly installed at the bottom of the equipment frame body 1. A positioning ring seat 2 is fixedly installed inside the equipment frame body 1.

The glue coating mechanism 6, the glue pumping mechanism 7 and the conveying mechanism 8 can be driven to operate by a driving motor 608, so as to automatically apply glue to the mold core, with high automation and improved processing efficiency.

[0030] As Figure 4 , Figure 5 and Figure 6 As shown in the figure, the glue coating mechanism 6 includes a movable rotating ring 601 movably installed inside the positioning ring seat 2. A driving gear ring 602 is fixedly installed on the outer side of the movable rotating ring 601. A driving motor 608 is fixedly installed below the movable rotating ring 601. A driving shaft 610 is provided at the output end of the driving motor 608. A driving gear 609 is fixedly installed on the driving shaft 610. A glue groove 603 is formed on the movable rotating ring 601. A rotating sealing cover 604 is provided at the glue groove 603.

A docking port 612 is formed on the rotating sealing cover 604.

[0031] Specifically, the driving motor 608 can drive the driving gear 609 to rotate, thereby driving the driving gear ring 602 to rotate. After the driving gear ring 602 rotates, it will drive the movable rotating ring 601 to rotate, so that the glue coating brush 605 on the positioning support column 607 rotates around the mold core, automatically applying glue to the mold core, improving the processing efficiency. And the first spring 606 will push the glue coating brush 605 to abut against the mold core to ensure uniform glue application.

[0032] As Figure 4 , Figure 5 and Figure 7As shown in the figure, the glue pumping mechanism 7 includes a glue storage tank 701 fixedly installed in the positioning base 5. Above the glue storage tank 701, a cylinder block 704 is fixedly installed. Inside the cylinder block 704, a second spring 705 is provided. Inside the cylinder block 704, a piston 706 is movably installed. A cam 707 is fixedly installed on the drive shaft 610, and the cam 707 is aligned with the piston 706 front and back. The cylinder block 704 is provided with a first pipeline 702 and a second pipeline 703, and one-way valves are provided in both the first pipeline 702 and the second pipeline 703. The one-way valve in the second pipeline 703 only allows the glue in the glue storage tank 701 to enter the cylinder block 704, and the one-way valve in the first pipeline 702 only allows the glue in the cylinder block 704 to enter the glue trough 603.

[0033] Specifically, the second spring 705 provides elastic force for the piston 706, thereby driving the piston 706 in the cylinder block 704 to reset. The cam 707 can be driven to rotate by the drive motor 608. After the cam 707 rotates, it will reciprocally press the piston 706. After reciprocally pressing the piston 706, the glue in the cylinder block 704 will be squeezed into the glue trough 603. The glue squeezed into the glue trough 603 will be transported to the bristles on the glue brush 605 by the delivery pipe 611, thereby continuously providing glue for the glue brush 605.

[0034] As Figure 4 、 Figure 5 and Figure 8 shown in the figure, the conveying mechanism 8 includes a mechanism housing 803 fixedly installed at the upper end of the positioning base 5. A movable shaft 804 is movably installed on the mechanism housing 803. A linkage gear 802 is fixedly installed at the middle position of the movable shaft 804.

A speed reducer 805 is provided on the transmission shaft 806. Bearings are provided on the mechanism housing 803, and the movable shaft 804 is movably installed in the mechanism housing 803 through the bearings. Helical gears 807 are provided on both the transmission shaft 806 and the drive shaft 610, and the two sets of helical gears 807 mesh with each other.

[0035] Specifically, the helical gear 807 can be driven to rotate by the drive motor 608. After the helical gear 807 rotates, it will drive the transmission shaft 806 to rotate. After being decelerated by the speed reducer 805, the transmission shaft 806 will drive the movable shaft 804 to rotate. Under the action of the linkage gear 802, the movable shaft 804 will drive the two conveying rollers 801 to rotate, thereby automatically conveying the mold core forward, and the degree of automation is high during the entire processing process, improving the processing efficiency.

[0036] Working principle: When in use, first fix the end of the carbon fiber bundle on the winding head 3 to the mold core. After the end of the carbon fiber bundle is fixed to the mold core, the winding head 3 can be controlled to rotate, so as to wind the carbon fiber bundle around the mold core. During the winding process of the carbon fiber bundle, the driving motor 608 can be started. After starting the driving motor 608, it will drive the driving shaft 610 to rotate. After the driving shaft 610 rotates, it will drive the driving gear 609, the cam 707 and the helical gear 807 to rotate simultaneously. After the driving gear 609 rotates, it will drive the driving gear ring 602 to rotate. After the driving gear ring 602 rotates, it will drive the movable ring 601 to rotate. After the movable ring 601 rotates, it will drive the positioning pillar 607 to rotate. After the positioning pillar 607 rotates, it will drive the glue brush 605 to rotate around the mold core, so as to automatically apply glue to the mold core, improving the processing efficiency. At the same time, the first spring 606 will push the glue brush 605 forward, making the glue brush 605 contact the mold core to ensure uniform glue application. After the cam 707 rotates, it will reciprocally press the piston 706. When the cam 707 releases the piston 706, the second spring 705 will push the piston 706 to reset, so as to suck the glue in the glue storage tank 701 into the cylinder body 704. When the cam 707 presses the piston 706, the glue in the cylinder body 704 will be squeezed into the glue groove 603. The glue squeezed into the glue groove 603 will be transported to the bristles on the glue brush 605 by the delivery pipe 611, so as to continuously provide glue for the glue brush 605, enabling the glue brush 605 to continuously apply glue. After the helical gear 807 rotates, it will drive the transmission shaft 806 to rotate. After being decelerated by the speed reducer 805, the transmission shaft 806 will drive the movable shaft 804 to rotate. Under the action of the linkage gear 802, the movable shaft 804 will drive the two groups of conveying rollers 801 to rotate, so as to convey the mold core forward automatically.
