Description

A granulation device for carbon-based composite high thermal conductivity nylon material Technical Field

[0001] This utility model belongs to the field of granulation machine technology, specifically a granulation device for carbon-based composite high thermal conductivity nylon material. Background Technology

[0002] Carbon-based composite high thermal conductivity nylon material is a new type of material that combines carbon-based thermally conductive fillers (such as carbon fiber, graphene, etc.) with a nylon matrix. It has excellent thermal conductivity, good mechanical properties and processing performance, and is widely used in fields that require efficient heat dissipation, such as LED lighting, automotive electronics, and 5G communication equipment.

[0003] During the manufacturing process, the granulator first heats and melts the nylon material using an extrusion device. Then, the molten nylon material is extruded through a shaping device to form long strips of nylon. Next, these nylon strips are sent to a cooling assembly for cooling and shaping. After cooling, the nylon strips then enter a cutting assembly and are finally cut into granules.

[0004] After the cutting assembly processes the nylon strip, granular nylon material accumulates in front of the cutting assembly, which can affect the cutting assembly's ability to granulate the nylon strip and cause the nylon granules to be cut again.

[0005] Therefore, this utility model provides a granulation device for carbon-based composite high thermal conductivity nylon material. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A granulation device for carbon-based composite high thermal conductivity nylon material, comprising an extrusion mechanism; a cooling mechanism is provided at one end of the extrusion mechanism, and a cutting box is provided at the other end of the cooling mechanism. A worktable is fixedly connected to the bottom of the cutting box, a motor is fixedly connected to one end of the cutting box, and a rotating shaft is fixedly connected to one end of the motor. The rotating shaft is rotatably connected to the cutting box. Multiple blades are fixedly connected to the outside of the rotating shaft. Multiple first air holes are provided on one side of each blade, and the first air holes are opened on the surface of the rotating shaft. A first external air pipe is provided at the other end of each blade, and a baffle is connected to one end of the first external air pipe. The baffle extends into the interior of the rotating shaft and is rotatably connected to the rotating shaft. During operation, the extrusion mechanism heats and melts the nylon material. Subsequently, the molten nylon material is extruded through the outlet of the extrusion mechanism to form long strips of nylon. Then, these nylon strips are sent to the cooling mechanism for cooling and shaping. After cooling treatment... The nylon strip then enters the cutting box. The motor starts, driving the shaft to rotate, which in turn drives the blade to rotate. The nylon strip is cut by the blade and finally cut into granules. The first external air pipe is connected to an air pump, and the gas is transmitted to a baffle through the first external air pipe. The baffle blocks the feed inlet of the cutting box, and the gas is transmitted out through the first air hole in the discharge direction of the cutting box. The airflow blows the nylon granules towards the outlet, reducing the accumulation of nylon granules at the discharge outlet of the cutting box. At the same time, the airflow dries the moisture on the nylon granules. During this process, the shaft rotates, and the baffle is sleeved inside the shaft. The shaft rotates around the baffle, which ensures that the airflow only goes to the first air hole in the discharge direction of the cutting box. By setting the baffle to guide the gas transmitted by the first external air pipe, the accumulation of nylon granules at the blade is reduced, which would affect the cutting of the nylon strip and the re-cutting of the nylon granules. The gas acts on the nylon granules, accelerating the drying of the moisture and preventing the nylon granules from sticking together due to water.

[0008] Preferably, a sieve plate is fixedly connected to the middle of the workbench, and a water collection tank is provided at the bottom of the sieve plate. The water collection tank is fixedly connected to the workbench. During operation, when the nylon belt is cut by the blade, the water on the nylon belt will pass through the sieve plate and flow into the water collection tank. Unqualified nylon particles will also fall into the water collection tank. This ensures that the nylon particles coming out of the cutting box are dry and qualified products.

[0009] Preferably, the outer side of the baffle is provided with multiple balls, which are rotatably connected to the baffle. During operation, the baffle remains stationary inside the rotating shaft, while the rotating shaft rotates outside the baffle. To reduce jamming, the balls provide auxiliary lubrication for the rotation of the rotating shaft. The balls support the rotating shaft, reducing contact between the baffle and the rotating shaft and thus preventing the rotating shaft from rotating poorly.

[0010] Preferably, the cooling mechanism has multiple pressure rods in the middle, one end of each pressure rod is connected to a second external air pipe, and the top of each pressure rod has multiple second air holes. During operation, the nylon strip floats on the surface as it passes through the cooling mechanism. The pressure rods apply pressure to the nylon strip to ensure that it is completely inside the cooling mechanism. The second external air pipe is connected to cold air. After the cold air enters the pressure rod, it is released from the second air holes. The cold air carries away the heat inside the cooling mechanism and removes it from the cooling mechanism, reducing the cooling effect on the nylon strip caused by the cooling mechanism absorbing excessive heat.

[0011] Preferably, a protective ring is provided on one side of the second air hole. The protective ring is rotatably connected to the pressure rod. During operation, the nylon strip slides at the bottom of the pressure rod, which will generate friction. The protective ring provides a barrier between the nylon strip and the pressure rod, reducing the damage to the nylon strip due to excessive friction. At the same time, the protective ring can separate the nylon strips one by one to prevent them from sticking together.

[0012] Preferably, a sealing ring is fitted around the outside of the first external air tube. The sealing ring is fixedly connected to the cutting box. During operation, the sealing ring fills the gap between the first external air tube and the cutting box, increasing air tightness and allowing more airflow to pass through the first air hole and act on the nylon particles.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The granulation device for carbon-based composite high thermal conductivity nylon material of this utility model reduces the accumulation of nylon particles at the blade by setting a baffle to guide the gas delivered by the first external gas pipe, thereby reducing the phenomenon that the blade affects the cutting of nylon strips and the nylon particles being cut again. The gas acts on the nylon particles, accelerating the drying of the nylon particles and preventing the nylon particles from sticking together due to water.

[0015] 2. The granulation device for carbon-based composite high thermal conductivity nylon material described in this utility model, by setting a sieve plate, allows the moisture on the nylon belt to pass through the sieve plate and flow into the water collection tank, while unqualified nylon particles will also fall into the water collection tank. This ensures that the nylon particles coming out of the cutting box are dry and qualified products. Attached Figure Description

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As shown in Figures 1 to 3, the granulation device for a carbon-based composite high thermal conductivity nylon material according to an embodiment of this utility model includes an extrusion mechanism 101; a cooling mechanism 102 is provided at one end of the extrusion mechanism 101, a cutting box 103 is provided at one end of the cooling mechanism 102, a worktable 1 is fixedly connected to the bottom of the cutting box 103, a motor 11 is fixedly connected to one end of the cutting box 103, a rotating shaft 12 is fixedly connected to one end of the motor 11, the rotating shaft 12 is rotatably connected to the cutting box 103, and multiple blades 13 are fixedly connected to the outside of the rotating shaft 12. The blade 13 has multiple first air holes 14 on one side, which are formed on the surface of the rotating shaft 12. The other end of the blade 13 has a first external air pipe 15, one end of which is connected to a baffle 16. The baffle 16 extends into the rotating shaft 12 and is rotatably connected to it. The extrusion mechanism 101 heats and melts the nylon material. The molten nylon material is then extruded through the outlet of the extrusion mechanism 101 to form long strips of nylon. These nylon strips are then fed into a cooling mechanism 102 for cooling and shaping. The processed nylon strip then enters the cutting box 103. The motor 11 starts, driving the rotating shaft 12 to rotate, which in turn drives the blade 13 to rotate. The nylon strip is cut by the blade 13 and ultimately cut into granules. The first external air pipe 15 is connected to an air pump, and gas is transmitted through the first external air pipe 15 to a baffle 16. The baffle 16 blocks the feed inlet of the cutting box 103, and the gas is transmitted out through the first air hole 14 at the discharge outlet of the cutting box 103. The airflow blows the nylon granules towards the outlet, reducing the accumulation of nylon granules at the discharge outlet of the cutting box 103. Simultaneously, the air... The airflow dries the moisture on the nylon particles. During this process, the rotating shaft 12 rotates, and the baffle 16 is fitted inside the rotating shaft 12. The rotating shaft 12 rotates around the baffle 16, which ensures that the airflow only goes to the first air hole 14 in the direction of the discharge port of the cutting box 103. By setting the baffle 16 to guide the gas delivered by the first external air pipe 15, the accumulation of nylon particles at the blade 13 is reduced, which would affect the cutting of the nylon strip by the blade 13 and the phenomenon of the nylon particles being cut again. The gas acts on the nylon particles, speeding up the drying of the nylon particles and preventing the nylon particles from sticking together due to water.

[0025] As shown in Figure 3, a sieve plate 2 is fixedly connected to the middle of the workbench 1. A water collection tank 21 is provided at the bottom of the sieve plate 2. The water collection tank 21 is fixedly connected to the workbench 1. When the nylon belt is cut by the blade 13, the water on the nylon belt will pass through the sieve plate 2 and flow into the water collection tank 21. Unqualified nylon particles will also fall into the water collection tank 21. This ensures that the nylon particles coming out of the cutting box 103 are dry and qualified products.

[0026] As shown in Figure 4, a plurality of balls 3 are provided on the outer side of the baffle 16. The balls 3 are rotatably connected to the baffle 16. The baffle 16 remains stationary inside the rotating shaft 12, while the rotating shaft 12 rotates outside the baffle 16. In order to reduce jamming, the balls 3 provide auxiliary lubrication for the rotation of the rotating shaft 12. The balls 3 support the rotating shaft 12, reducing contact between the baffle 16 and the rotating shaft 12 and thus reducing the possibility of the rotating shaft 12 not rotating smoothly.

[0027] As shown in Figure 5, the cooling mechanism 102 has multiple pressure rods 4 in the middle. One end of each pressure rod 4 is connected to a second external air pipe 41. The top of each pressure rod 4 has multiple second air holes 42. When the nylon strip passes through the cooling mechanism 102, it floats on the surface. The pressure rods 4 apply pressure to the nylon strip to ensure that it completely enters the cooling mechanism 102. The second external air pipe 41 is connected to cold air. After the cold air enters the pressure rod 4, it is released from the second air holes 42. The cold air will carry away the heat inside the cooling mechanism 102 and remove it from the cooling mechanism 102, thus reducing the cooling effect on the nylon strip caused by the cooling mechanism 102 absorbing excessive heat.

[0028] As shown in Figure 5, a protective ring 5 is provided on one side of the second air hole 42. The protective ring 5 is rotatably connected to the pressure rod 4. The nylon strip slides at the bottom of the pressure rod 4, which will generate friction. The protective ring 5 provides a barrier between the nylon strip and the pressure rod 4 to reduce the damage caused by excessive friction on the nylon strip. At the same time, the protective ring 5 can separate the nylon strips one by one to prevent them from sticking together.

[0029] As shown in Figures 2 to 4, a sealing ring 6 is fitted around the outside of the first external air tube 15. The sealing ring 6 is fixedly connected to the cutting box 103. The sealing ring 6 fills the gap between the first external air tube 15 and the cutting box 103, increasing the airtightness and allowing more airflow to pass through the first air hole 14 and act on the nylon particles.

[0030] Working principle: The extrusion mechanism 101 heats and melts the nylon material. The molten nylon material is then extruded through the outlet of the extrusion mechanism 101 to form long strips of nylon. These nylon strips are then fed into the cooling mechanism 102 for cooling and shaping. After cooling, the nylon strips enter the cutting box 103. The motor 11 starts, driving the rotating shaft 12 to rotate, which in turn drives the blade 13 to rotate. The nylon strip is cut by the blade 13 and ultimately cut into granules. The first external air pipe 15 is connected to an air pump, and gas is transmitted through the first external air pipe 15 to the baffle 16. The baffle 16 blocks the feed inlet of the cutting box 103, and the gas passes through the first air hole 14 at the discharge outlet of the cutting box 103. As the material is conveyed out, the airflow propels the nylon granules towards the outlet, reducing their accumulation at the discharge port of the cutting box 103. Simultaneously, the airflow dries the moisture on the nylon granules. During this process, the rotating shaft 12 rotates, with a baffle 16 fitted inside. The shaft 12 rotates around the baffle 16, ensuring that the airflow only reaches the first air hole 14 in the direction of the discharge port of the cutting box 103. By guiding the gas delivered by the first external air pipe 15 through the baffle 16, the accumulation of nylon granules at the blade 13 is reduced, thus minimizing the impact on the blade's ability to cut the nylon strip and prevent the nylon granules from being cut again. The gas acts on the nylon granules, accelerating the drying process and preventing them from sticking together due to water. When the nylon belt is cut by the blade 13, the moisture on the nylon belt will pass through the screen plate 2 and flow into the water collection tank 21. Unqualified nylon particles will also fall into the water collection tank 21. This ensures that the nylon particles coming out of the cutting box 103 are dry and qualified products. The baffle 16 remains stationary inside the rotating shaft 12, while the rotating shaft 12 rotates outside the baffle 16. To reduce jamming, the ball bearings 3 provide auxiliary lubrication for the rotation of the rotating shaft 12. The ball bearings 3 support the rotating shaft 12, reducing contact between the baffle 16 and the rotating shaft 12, which could cause the rotating shaft 12 to rotate unevenly. When the nylon belt passes through the cooling mechanism 102, it will float on the surface. The pressure rod 4 applies pressure to the nylon belt to ensure that it completely enters the cooling mechanism 102. The external air pipe 41 is connected to cold air. After the cold air enters the pressure rod 4, it is emitted from the second air hole 42. The cold air will carry away the heat in the cooling mechanism 102 and remove it from the cooling mechanism 102, reducing the cooling effect of the cooling mechanism 102 on the nylon belt due to excessive heat absorption. The nylon belt slides at the bottom of the pressure rod 4, which will generate friction. The protective ring 5 provides a barrier between the nylon belt and the pressure rod 4 to reduce the damage caused by excessive friction on the nylon belt. At the same time, the protective ring 5 can separate the nylon belts one by one to prevent them from sticking together. The sealing ring 6 fills the gap between the first external air pipe 15 and the cutting box 103 to increase air tightness, so that more airflow passes through the first air hole 14 and acts on the nylon particles.
