Description

Technical Field

[0001] This utility model relates to the field of nylon preparation technology, and in particular to a preparation equipment for composite reinforced flame-retardant nylon materials for new energy vehicles. Background Technology

[0002] Composite reinforced flame-retardant nylon material is a high-performance engineering plastic that combines flame-retardant properties with mechanical reinforcement. New energy vehicles contain components such as high-voltage battery packs and charging interfaces that are prone to fire.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution:

[0026] Please see Figures 1 to 4A device for preparing composite reinforced flame-retardant nylon material for new energy vehicles includes a mixing chamber 1. The mixing chamber 1 is equipped with a crushing component 4 for crushing materials and a mixing component 3 for mixing materials. A connecting pipe 6 is fixed at the bottom of the mixing chamber 1, and a heating component 2 is provided at the end of the connecting pipe 6. A feeding pipe 5 is fixed at the top of the mixing chamber 1, and a guide pipe 7 is fixed at the output end of the feeding pipe 5.

[0027] The crushing assembly 4 includes a support frame 403 fixed inside the mixing chamber 1. A crushing shaft 401 is inserted inside the support frame 403, and crushing blades 402 are fixed around the crushing shaft 401. An adjusting screw 404 is fixed at the bottom of the crushing shaft 401, and a lifting slider 405 is connected to the outside of the adjusting screw 404 through a screw sleeve. A filter screen 406 is fixed to the outside of the lifting slider 405. A guide rod 407 is also inserted inside the lifting slider 405, and the guide rod 407 is fixed to the bottom of the support frame 403.

[0028] By adopting the above technical solution, nylon matrix resin, flame retardant reinforcing fibers, and other additives are fed into the guide pipe 7 through the feed pipe 5 and crushed by the crushing assembly 4. When the material passes through the crushing blades 402, the rotating crushing shaft 401 drives the crushing blades 402 to rotate at high speed, thus crushing the material. The crushed material can be filtered by the filter screen 406 and falls to the bottom of the mixing chamber 1. At the same time, the adjusting screw 404 is a reciprocating screw. When the crushing shaft 401 rotates, it can drive the adjusting screw 404 to rotate simultaneously. Under the action of the guide rod 407, the lifting slider 405 moves on the adjusting screw 404 through the screw sleeve, which can drive the filter screen 406 to rotate. 06 moves downwards until the filter screen 406 moves to the lowest end of the guide rod 407. As the adjusting screw 404 continues to rotate, the filter screen 406 moves upwards, transporting the unpassed raw material upwards to the vicinity of the crushing blade 402. The crushing blade 402 crushes it again until all the raw material is crushed and filtered through the filter screen 406. Through the set crushing component 4, the input material can be crushed under the action of the crushing blade 402. And with the up-and-down movable filter screen 406, the uncrushed material is driven up and down until all the material is filtered out through the filter screen 406, realizing the crushing of the material. After the material particles are reduced in size, they can be melted quickly, shortening the heating time.

[0029] Specifically, such as Figure 3 and Figure 4As shown, the mixing assembly 3 includes a servo motor 301 fixed in the middle of the top of the mixing chamber 1, and a drive shaft 303 fixed to the power output end of the servo motor 301. A drive gear 304 is fixed to the end of the drive shaft 303, and a driven gear 305 is meshed with one side of the drive gear 304. A gearbox 302 is provided outside the driven gear 305 and the drive gear 304. A dispersing disk 306 is fixed to the power output end of the driven gear 305, and the dispersing disk 306 is located at the bottom of the output end of the guide pipe 7. The mixing assembly 3 also includes a mixing shaft 308 fixed to the bottom of the adjusting screw 404, and a mixing rod 307 is fixed to the surface of the mixing shaft 308. An anti-blocking rod 309 is fixed to the surface of the mixing shaft 308 below the mixing rod 307. The anti-blocking rod 309 is located inside the connecting pipe 6.

[0030] The heating assembly 2 includes a conveying chamber 201 fixed to the bottom of the connecting pipe 6. A conveying motor 202 is fixedly connected to one side of the conveying chamber 201, and an auger screw 206 is fixed to the power output end of the conveying motor 202. An electric heating inner rod 207 is fixed inside the auger screw 206. A fixing sleeve 204 is fixed to the outside of the conveying chamber 201, and multiple heating rods 203 are sandwiched between the fixing sleeve 204 and the conveying chamber 201. A discharge pipe 205 is fixed to the bottom of the conveying chamber 201.

[0031] By adopting the above technical solution, after the servo motor 301 is started, the power output end of the servo motor 301 drives the drive gear 304 to rotate through the transmission shaft 303. Under the action of the teeth, the drive gear 304 drives the driven gear 305 to rotate, and the driven gear 305 drives the dispersing disk 306 to rotate. When the material enters the top of the dispersing disk 306, it is dispersed outward with the rotating dispersing disk 306, and the material is initially broken up. Furthermore, under the drive of the adjusting screw 404, the mixing shaft 308 can drive the mixing rod 307 and the anti-blocking rod 309 to rotate, thereby fully mixing the crushed material. The size of the anti-blocking rod 309 is related to the connecting pipe. The inner diameters of the 6 components are matched, and the mixed material enters the heating component 2. At the same time, the electric heating inner rod 207 and the heating rod 203 are connected to the power supply. The electric heating inner rod 207 and the heating rod 203 heat the material from the inside and outside. The material is conveyed to the discharge pipe 205 by one end of the auger screw 206 and discharged outward from the discharge pipe 205. It can then be injected into the injection molding device, cooled and formed. Through the set mixing component 3, the material can be initially dispersed under the action of the dispersing plate 306, so that the material enters the mixing chamber 1. Under the action of the mixing shaft 308, the mixing rod 307 and the anti-blocking rod 309 are rotated, thereby fully mixing the crushed material.

[0032] Working Principle: Nylon matrix resin, flame retardant reinforcing fibers, and other additives are fed into the guide pipe 7 through the feed pipe 5 and fall onto the dispersion disc 306. The power output end of the servo motor 301 drives the drive gear 304 to rotate through the transmission shaft 303. Under the action of the teeth, the drive gear 304 drives the driven gear 305 to rotate, which in turn drives the dispersion disc 306 to rotate. When the material enters the top of the dispersion disc 306, it is dispersed outward with the rotating dispersion disc 306, which initially breaks down the material and reaches the area around the crushing blades 402. With the rotation of the crushing shaft 401, the crushing blades 402 rotate at high speed, thus crushing the material. The crushed material can be filtered by the filter screen 406 and falls into the bottom of the mixing chamber 1. At the same time, the adjusting screw 404 is a reciprocating screw. When the crushing shaft 401 rotates, it can drive the adjusting screw 404 to rotate simultaneously. Under the action of the guide rod 407, the lifting slider 405 moves through the screw sleeve. Moving the adjusting screw 404 upwards causes the filter screen 406 to move downwards until it reaches the lowest point of the guide rod 407. As the adjusting screw 404 continues to rotate, the filter screen 406 moves upwards, transporting any unpassed material upwards to the vicinity of the crushing blades 402. The crushing blades 402 then further crush the material until all the material is crushed and passes through the filter screen 406. Driven by the adjusting screw 404, the mixing shaft 308 rotates the mixing rod 307 and the anti-blocking rod 309, thus fully mixing the crushed material. The size of the anti-blocking rod 309 is compatible with the inner diameter of the connecting pipe 6. The mixed material enters the heating assembly 2, and the electric heating inner rod 207 and the heating rod 203 are simultaneously powered on. The electric heating inner rod 207 and the heating rod 203 heat the material from the inside and outside. The material is conveyed from one end of the auger screw 206 to the discharge pipe 205 and discharged outwards. It can then be injection molded by the injection molding device and cooled to form a finished product.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
