Description

Technical Field

[0001] The invention relates to the technical field of polymer materials, and in particular to a preparation method and device of a high-strength fiber-reinforced synthetic resin composite material. Background Art

[0002] High-strength fiber-reinforced synthetic resin composites have shown great application potential in many fields due to their excellent performance. For example, in the aerospace field, their light weight and high strength characteristics help reduce the weight of aircraft, improve fuel efficiency and flight performance; in the automotive field, they can be used to manufacture body structural parts to improve the safety and fuel economy of automobiles; in the military field, they can provide better protection and performance for military equipment.

[0003] At present, common high-strength fiber-reinforced synthetic resin composite materials mainly include carbon fiber-reinforced resin-based composite materials, plant fiber-reinforced resin-based composite materials, etc. The preparation methods of these materials are different, but they all aim to achieve a good combination of fiber and resin and improve the performance of composite materials. In the preparation process, we will find that the artificially proportioned raw materials and processing additives are generally inverted in the mixing kettle at one time, and then mixed and stirred using a stirring device. The stirring paddle is in a fixed position inside the kettle, and the stirring paddle is driven by a motor to rotate to mix the raw materials. Commonly used ester base materials such as polyacrylates generally use a few millimeters to more than ten millimeters according to production requirements. Commonly used additives such as defoamers generally use a few microns to tens of microns according to production requirements. Since the particle size of the additive is smaller than the particle size of the base material, when the stirring paddle is always in the same position for stirring, the additive is easy to fall from the gap between the base material particles to the bottom of the kettle, resulting in the problem of high additive content at the bottom and low additive content at the top of the stirred raw material, resulting in deviations in the quality of the raw materials melted by the subsequent extrusion equipment.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In this solution, under the action of the designed driving unit 2, the large gear ring 9 and the lifting unit 3, the stirring unit 4 can be driven to move up and down reciprocatingly while the mixing kettle body 1 rotates, so that the stirring height of the stirring unit 4 inside the mixing kettle body 1 can be flexibly and continuously adjusted. In the process of the stirring unit 4 stirring from the bottom of the mixing kettle body 1 upward, it can effectively drive the additives at the bottom of the mixing kettle body 1 upward, thereby significantly improving the uniformity of the raw material mixing. This improvement not only optimizes the mixing effect, but also may improve the quality of the final product, ensuring the efficiency and stability of the production process.

[0026] For further information, see Figure 3 The driving unit 2 includes a driving motor 201, a driving shaft 202, a first bevel gear set 203, a first transmission shaft 204 and a first transmission gear 205. The driving motor 201 is fixedly connected to the first annular frame 6, and the driving shaft 202 is fixedly connected to the output end of the driving motor 201 through a coupling. The input end of the first bevel gear set 203 is fixed to the driving shaft 202, and the output end is fixedly connected to the first transmission shaft 204. The first transmission gear 205 is fixedly connected to the top of the first transmission shaft 204, and the large gear ring 9 is meshed with the first transmission gear 205. The driving shaft 202 is rotatably connected to the first limit seat 206 through a bearing, and the bottom of the first limit seat 206 is fixedly connected to the first annular frame 6. The first transmission shaft 204 is rotatably connected to the second limit seat 207 through a bearing, and one side of the second limit seat 207 is fixedly connected to the first limit seat 206.

[0027] Specifically, by starting the drive motor 201, the drive motor 201 drives the drive shaft 202 to rotate, and the drive shaft 202 then drives the first transmission shaft 204 to rotate through the first bevel gear set 203, the first transmission shaft 204 drives the first transmission gear 205 to rotate, the first transmission gear 205 drives the large ring gear 9 to rotate, the large ring gear 9 drives the annular connecting plate 8 to rotate, and the annular connecting plate 8 drives the mixing kettle body 1 to rotate, thereby generating relative motion with the stirring unit 4 inside the mixing kettle body 1 to mix and stir the added materials.

[0028] For further information, see Figure 4 The lifting unit 3 includes a second transmission shaft 301, a crank 302, a connecting rod 303, a second bevel gear set 304, a third transmission shaft 305 and a second transmission gear 306. The crank 302 is fixedly connected to one end of the second transmission shaft 301, the connecting rod 303 is rotatably connected to one end of the crank 302, the top of the crank 302 is rotatably connected to the lifting plate 14, the input end of the second bevel gear set 304 is fixedly connected to the second transmission shaft 301, and the output end of the second bevel gear set 304 is fixedly connected to the third transmission shaft 305. The second transmission gear 306 is fixedly connected to the top of the third transmission shaft 305, the large gear ring 9 is meshingly connected to the second transmission gear 306, the second transmission shaft 301 is rotatably connected to the third limit seat 307 through a bearing, the bottom of the third limit seat 307 is fixedly connected to the first annular frame 6, the third transmission shaft 305 is rotatably connected to the fourth limit seat 308 through a bearing, one side of the fourth limit seat 308 is fixedly connected to the third limit seat 307, and an oil replenishing unit 5 is installed between the lifting plate 14 and the top plate 12.

[0029] Also, see Figure 3 A return spring 16 is fixed to the bottom of the lifting plate 14, and the bottom of the return spring 16 is fixedly connected to the second annular plate. The slide rod 13 runs through the inside of the return spring 16. When the connecting rod 303 applies a force to the lifting plate 14 to cause it to move, the return spring 16 can provide a restoring force to make the lifting plate 14 return to its initial position when the force of the connecting rod 303 disappears or weakens.

[0030] Specifically, when the large gear ring 9 rotates, it will also drive the second transmission gear 306 to rotate, the second transmission gear 306 drives the third transmission shaft 305 to rotate, the third transmission shaft 305 drives the second transmission shaft 301 to rotate through the second bevel gear set 304, the second transmission shaft 301 drives the crank 302 to rotate, and the crank 302 drives the lifting plate 14 to reciprocate up and down on the outside of the slide bar 13 through the connecting rod 303, thereby driving the stirring unit 4 connected to the lifting plate 14 to move back and forth up and down, so that the stirring height of the stirring unit 4 inside the mixing kettle body 1 can be flexibly and continuously adjusted. In the process of stirring the stirring unit 4 from the bottom of the mixing kettle body 1 upward, it can effectively drive the additives at the bottom of the mixing kettle body 1 upward, thereby significantly improving the uniformity of raw material mixing.

[0031] Example 2: Please refer to Figure 5 This embodiment further explains the first embodiment, and the difference lies in that the structure of the stirring part is optimized.

[0032] Specifically, the stirring unit 4 in the figure includes a mounting shell 401, a connecting cylinder 402, a third bevel gear set 403, a fourth transmission shaft 404, a stirring rod 405 and a stirring paddle 406. The mounting shell 401 is arranged in an array, and the plurality of mounting shells 401 are fixedly connected through the connecting cylinder 402. The third bevel gear set 403 is arranged inside the mounting shell 401, and the fourth transmission shaft 404 passes through the inside of the mounting shell 401 and the connecting cylinder 402 respectively. The input end of the third bevel gear set 403 is fixedly connected to the fourth transmission shaft 404, and the fourth transmission shaft 404 is rotatably connected to the connecting cylinder 402 through a bearing. The two bevel gears at the output end of the third bevel gear set 403 The gears are all fixedly connected with a fifth transmission shaft 407, which is rotatably connected to the mounting shell 401 through a bearing, and one end of the fifth transmission shaft 407 extending outside the mounting shell 401 is fixedly connected to the stirring rod 405 through a coupling, and the stirring paddle 406 is evenly distributed on the outside of the stirring rod 405. One end of the connecting cylinder 402 located at the top is fixedly connected to the bottom of the connecting block 15, and a cavity is opened inside the connecting block 15. The top end of the fourth transmission shaft 404 extends into the cavity and is transmission-connected with a fourth bevel gear set 408, and a linkage member 409 for realizing the transmission of the fourth bevel gear set 408 is provided between the second annular frame 11 and the connecting block 15; Also, see Figure 6 The linkage member 409 includes a fixed rack 4091, a mobile gear 4092 and a linkage shaft 4093. The bottom of the fixed rack 4091 is fixed to the top of the second annular frame 11, and the mobile gear 4092 is meshed with the fixed rack 4091. One end of the linkage shaft 4093 is fixedly connected to the mobile gear 4092, and the other end extends into the cavity and is fixedly connected to the input end of the fourth bevel gear set 408. The linkage shaft 4093 is rotatably connected to the connecting block 15 through a bearing.

[0033] Specifically, when the lifting plate 14 moves up and down, it will drive the moving gear 4092 to move up and down. Since the moving gear 4092 and the fixed rack 4091 maintain a meshing relationship, the moving gear 4092 will also rotate. The moving gear 4092 drives the linkage shaft 4093 to rotate. The linkage shaft 4093 drives the fourth transmission shaft 404 to rotate through the fourth bevel gear set 408. The fourth transmission shaft 404 then drives multiple fifth transmission shafts 407 to rotate synchronously through the transmission action of multiple sets of third bevel gear sets 403. The fifth transmission shaft 407 drives the stirring rod 405 to rotate, and the stirring rod 405 drives the stirring paddle 406 to rotate. The stirring paddle 406 can also rotate while moving up and down, so that the material in the mixing kettle body 1 can be rolled more effectively, ensuring that the mixing between the raw materials and the additives achieves higher uniformity and accuracy. Through this all-round stirring action, the raw materials inside the mixing kettle body 1 can be more conveniently and fully stirred, thereby significantly improving the stirring efficiency.

[0034] Example 3: Please refer to Figure 7 and Figure 8 This embodiment further illustrates other embodiments, and the difference lies in optimizing the use environment of the large gear ring 9.

[0035] Specifically, the oil replenishing unit 5 includes a fixed plate 501, an injection cylinder 502, a piston block 503, a piston rod 504 and an annular oil delivery pipe 505. The fixed plate 501 is fixed on the top plate 12, the injection cylinder 502 is fixed on the fixed plate 501, the piston block 503 is slidably connected inside the injection cylinder 502, the piston rod 504 is fixedly connected to the bottom of the piston block 503, and one end of the piston rod 504 away from the piston block 503 passes through the injection cylinder 502 and the fixed plate 501 respectively, and is fixedly connected with a clutch 506. The top of the injection cylinder 502 is fixed to the fixed plate 501. An oil outlet pipe 5010 is connected to one side of the part through a one-way valve, and an end of the oil outlet pipe 5010 away from the injection cylinder 502 is fixedly connected to the annular oil delivery pipe 505, and fuel nozzles 507 are evenly distributed on the bottom of the annular oil delivery pipe 505, and the fuel nozzles 507 are facing the outer side of the large gear ring 9. The annular oil delivery pipe 505 is fixedly connected to the top plate 12 through a fixing rod, and the top of the injection cylinder 502 is connected to the oil inlet pipe 508 through a one-way valve, and an oil tank 509 is fixed to the end of the oil inlet pipe 508 away from the injection cylinder 502, and the oil tank 509 is arranged on the fixed base 7.

[0036] Specifically, since the large ring gear 9 needs to operate continuously, the wear between it and the transmission gear will gradually increase, so the large ring gear 9 needs to be maintained regularly. However, during maintenance, the lifting plate 14 and the piston rod 504 can be connected through the clutch 506, so that when the lifting plate 14 moves up and down, it will drive the piston rod 504 to slide back and forth inside the injection cylinder 502. When the piston rod 504 moves from top to bottom, it will drive the piston block 503 to move together, and the space above the piston block 503 will increase, thereby opening the one-way valve of the oil inlet pipe 508, and drawing the lubricating oil inside the oil tank 509 into the injection cylinder 502. Then, when the piston rod 504 moves from bottom to top, the one-way valve of the oil outlet pipe 5010 opens automatically, and the drawn lubricating oil enters the annular oil delivery pipe 505 through the oil outlet pipe 5010, and finally is evenly sprayed out through multiple oil nozzles 507, so as to be evenly sprayed into the tooth grooves of the large ring gear 9, thereby performing lubrication maintenance operations on the large ring gear 9 and improving its service life.

[0037] Among them, see Figure 8 The clutch member 506 includes a fixed frame 5061, an electric push rod 5062 and a block 5064. The fixed frame 5061 is fixedly connected to the bottom end of the piston rod 504. The electric push rod 5062 is installed inside the fixed frame 5061. The block 5064 is fixedly connected to the telescopic end of the electric push rod 5062. A docking member 5063 is fixed on the lifting plate 14; the docking member 5063 includes a support column 50631 and a docking block 50632. The support column 50631 is fixed on the lifting plate 14. The support column 50631 is coaxially distributed with the piston rod 504. The docking block 50632 is fixed to the top of the support column 50631. The top of the docking block 50632 is provided with a slot 50633 adapted to the block 5064.

[0038] Specifically, when the large gear ring 9 needs to be maintained, the electric push rod 5062 is first used to drive the block 5064 to move downward, so that the block 5064 is inserted into the slot 50633 of the docking block 50632, thereby achieving docking and fixation between the fixed frame 5061, the piston rod 504 and the support column 50631, so that when the lifting plate 14 moves up and down, the piston rod 504 will be driven to move together, keeping the large gear ring 9 rotating while driving the various gears to rotate. When the large gear ring 9 rotates, it will have a contact splash effect on the sprayed lubricating oil, so that the gears on each drive unit 2 and the lifting unit 3 can also contact the lubricating oil, thereby improving the effect of splash lubrication.

[0039] A method for preparing a high-strength fiber-reinforced synthetic resin composite material comprises the following steps: S1: Prepare materials such as epoxy resin, phenolic resin, polyamide resin, polyvinyl chloride, diethyl phthalate, polyvinyl acetal, plasma-modified sodium bentonite, microporous coating enhancer, flame retardant, etc.

[0040] S2: Take epoxy resin, phenolic resin, polyamide resin and polyvinyl chloride and add them into the mixing kettle body 1, and carry out hydrothermal reaction at a temperature of 80-90°C for 3-5 hours until the mixture is uniformly mixed, and keep the temperature for 30-40 minutes, and use a jet mill to perform micronization treatment for 1-2 hours.
