It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0021] In one embodiment, see Figure 1 , Figure 2 , Figure 3 and Figure 4 A graphene raw material feeding device comprises a mixing box 1, a feeding channel 2 is fixed on the top of the mixing box 1, a feeding hopper 3 is fixed on the top of the feeding channel 2, a sealing cover 7 is fixed on the top of the mixing box 1, a rotating rod 8 is passed through the top of the sealing cover 7, the rotating rod 8 is rotatably connected to the top of the sealing cover 7, wherein the lower end of the rotating rod 8 is connected to a rotating part 12, the rotating part 12 is used to drive the rotating rod 8 to rotate, a baffle 9 is fixed on the top of the rotating rod 8, a transmission rod 10 is passed through the inside of the baffle 9, the transmission rod 10 is rotatably connected to the baffle 9, and the transmission rod 10 A plurality of stirring rods 11 are fixed on the outside, wherein a rotation mechanism 4 is connected to the upper end of a transmission rod 10, and when the transmission rod 10 moves in a circle, the rotation mechanism 4 is used to drive the transmission rod 10 to rotate, and a dispersion mechanism 6 is provided between the sealing cover 7 and the feeding channel 2, and the dispersion mechanism 6 is used to disperse the graphene raw material so that the graphene raw material can enter the mixing box 1 from different positions, and a scattering mechanism 5 is provided inside the feeding channel 2, and when the rotating rod 8 rotates, the scattering mechanism 5 is used to scatter the graphene raw material inside the feeding channel 2.

[0022] In the present embodiment, when the device is loading the graphene raw material, the graphene raw material is poured into the loading channel 2 through the loading hopper 3, and the rotating rod 8 is driven to rotate through the rotating part 12, and the rotating rod 8 drives the baffle 9 to rotate, and the baffle 9 drives the transmission rod 10 to make a circular motion. While the transmission rod 10 is moving in a circular motion, the graphene raw material is dispersed through the dispersion mechanism 6, so that the graphene raw material can enter the mixing box 1 from different positions, ensuring the uniformity of the graphene raw material falling into the mixing box 1, which is conducive to the subsequent full mixing of the graphene raw material. In addition, while the transmission rod 10 is moving in a circular motion, the rotation mechanism 4 also drives the transmission rod 10 to rotate, so that the stirring rod 11 can also rotate while moving in a circular motion. The stirring effect of the graphene raw material in the feeding channel 2 is effectively improved, thereby avoiding the blockage caused by the accumulation of graphene raw materials in the feeding channel 2, so that the graphene raw materials can smoothly enter the mixing box 1, wherein the rotating part 12 can be a motor, and the motor is installed in the sealing cover 7. The output end of the motor is fixedly connected to the bottom of the rotating rod 8, and the rotating rod 8 is driven by the motor to rotate. In addition, the rotating rod 8 drives the baffle 9 to rotate while also driving the breaking mechanism 5 to operate. The graphene raw material in the feeding channel 2 is broken up by the breaking mechanism 5, so that the graphene raw material becomes relatively loose, which can further avoid the accumulation of graphene raw materials in the feeding channel 2, thereby ensuring that the graphene raw material can smoothly enter the mixing box 1.

[0023] See also Figure 3The self-rotating mechanism 4 includes a gear 41 fixed to the top of the transmission rod 10, and a gear ring 42 is fixed to the inner wall of the feeding channel 2, and the gear ring 42 is meshed with the gear 41; The baffle 9 drives the transmission rod 10 to move in a circular motion while synchronously driving the gear 41 to move in a circular motion.

The meshing of the toothed ring 42 and the gear 41 drives the transmission rod 10 to rotate, so that the stirring rod 11 can rotate while moving in a circular motion, thereby ensuring the stirring effect of the stirring rod 11 on the graphene raw material, thereby avoiding the accumulation of graphene raw materials inside the feeding channel 2, and allowing the graphene raw materials to smoothly enter the mixing box 1.

[0024] See also Figure 4 The scattering mechanism 5 includes a connecting plate 55 fixed to the outside of the rotating rod 8, a cutting rope 51 is provided between the connecting plate 55 and the baffle 9, and the cutting rope 51 is connected to the baffle 9 and the connecting plate 55 through a lifting assembly. When the rotating rod 8 rotates, the lifting assembly is used to drive the cutting rope 51 to move up and down; When the rotating rod 8 rotates, it also drives the baffle plate 9 and the connecting plate 55 to rotate. The connecting plate 55 and the baffle plate 9 drive the cutting rope 51 to make a circular motion. When the cutting rope 51 makes a circular motion, it can break up the graphene raw material inside the feeding channel 2, and at the same time, it can also have a certain cutting effect on the agglomerated graphene raw material. On the one hand, it makes the graphene raw material become relatively loose, thereby avoiding the accumulation of graphene raw material inside the feeding channel 2. On the other hand, it can also avoid the agglomerated graphene raw material from entering the mixing box 1, thereby ensuring the subsequent mixing effect of the graphene raw material. In addition, when the cutting rope 51 makes a circular motion, the lifting assembly also drives the cutting rope 51 to move up and down, thereby making the cutting rope 51 move up and down while making a circular motion, further improving the breaking up effect of the graphene.

[0025] See also Figure 4 The lifting assembly includes a first slide bar 53 that passes through the baffle 9 and a second slide bar 56 that passes through the connecting plate 55, wherein the first slide bar 53 is slidably connected to the baffle 9, and the second slide bar 56 is slidably connected to the connecting plate 55, wherein a stopper 52 is fixed at the bottom of the first slide bar 53, and the bottom of the stopper 52 is fixedly connected to the upper end of the cutting rope 51, and a first elastic member 54 is fixed at the top of the stopper 52, and the upper end of the first elastic member 54 is fixedly connected to the bottom of the baffle 9, and the top of the second slide bar 56 is fixedly connected to the lower end of the cutting rope 51, and an extrusion block 57 is fixed at the bottom of the second slide bar 56, and an extrusion component is provided inside the feeding channel 2, and when the extrusion block 57 moves in a circle, the extrusion component is used to extrude the extrusion block 57, so that the extrusion block 57 moves downward; When the rotating rod 8 rotates, the first sliding rod 53 is driven to move in a circle through the baffle plate 9, and the second sliding rod 56 is driven to move in a circle through the connecting plate 55. The first sliding rod 53 and the second sliding rod 56 drive the cutting rope 51 to move in a circle, so that the cutting rope 51 can break up the graphene raw material, and when the cutting rope 51 moves in a circle, the extrusion component will squeeze the extrusion block 57, and the extrusion block 57 will pull the cutting rope 51 downward through the second sliding rod 56. When the extrusion component no longer squeezes the extrusion block 57, the first elastic member 54 can reset the block 52, thereby pulling the cutting rope 51 upward. The first elastic member 54 can be a spring. This cycle is repeated, so that the cutting rope 51 can move in a circle and can also continuously move up and down, thereby effectively improving the effect of breaking up the graphene raw material.

[0026] See also Figure 4 The extrusion component includes a retaining ring 58 fixed to the outside of the sealing cover 7, and a plurality of extrusion protrusions 59 distributed in a circumference and capable of extruding the extrusion block 57 are fixed to the bottom of the retaining ring 58; As the connecting plate 55 rotates, the extrusion block 57 is driven to move in a circle through the second sliding bar 56. When the extrusion block 57 rotates to the position of the extrusion protrusion 59, as the extrusion block 57 continues to rotate, the extrusion protrusion 59 will squeeze the extrusion block 57, so that the extrusion block 57 pulls the cutting rope 51 downward through the second sliding bar 56. When the extrusion block 57 passes over the extrusion protrusion 59, the extrusion protrusion 59 no longer squeezes the extrusion block 57, and the cutting rope 51 automatically resets under the action of the stop block 52 and the first elastic member 54.

[0027] See also Figure 2 , Figure 3 and Figure 5 The dispersing mechanism 6 includes a plurality of feed openings 61 arranged on the top of the mixing box 1 and distributed in a circumference, and a sealing plate 62 is arranged above each of the feed openings 61, and the bottom of the sealing plate 62 is slidably connected to the top of the mixing box 1, and the sealing plate 62 passes through the side wall of the feeding channel 2 and is slidably connected to the side wall of the feeding channel 2, and a fixing plate 64 is fixed to one end of the sealing plate 62 located outside the feeding channel 2, and a second elastic member 65 is fixed to one side of the fixing plate 64 close to the feeding channel 2, and the other end of the second elastic member 65 is fixedly connected to the outer wall of the feeding channel 2, and the fixing plate 64 is connected to a pushing component, and the pushing component is used to push the fixing plate 64; When the graphene raw material is being fed, the sealing plate 62 seals the feed opening 61 at the top of the mixing box 1, and the graphene raw material cannot enter the mixing box 1. When the transmission rod 10 rotates to the top of one of the sealing plates 62, the transmission rod 10 pushes the fixed plate 64 through the pushing component, and the fixed plate 64 drives the sealing plate 62 to move horizontally, thereby releasing the sealing plate 62 from blocking the feed opening 61. At this time, the graphene raw material in the feeding channel 2 can enter the mixing box 1 through the feed opening 61. When the transmission rod 10 passes over the sealing plate 62, the pushing component no longer pushes the fixed plate 64, and the fixed plate 64 moves horizontally in the second elastic movement. The second elastic member 65 can be a spring, so that the sealing plate 62 blocks the discharge port 61. With the circular motion of the transmission rod 10, the transmission rod 10 will push the remaining fixed plates 64 through the remaining pushing components, so that the remaining discharge ports 61 can be opened in turn, and this cycle is repeated. On the one hand, the purpose of intermittent discharge can be achieved, thereby avoiding the accumulation of graphene raw materials inside the mixing box 1, ensuring the subsequent mixing effect of the graphene raw materials. On the other hand, the graphene raw materials can be evenly dropped into the mixing box 1, further ensuring the subsequent mixing effect of the graphene raw materials.

[0028] See also Figure 3 and Figure 5 The pushing assembly includes a bracket 63 fixedly connected to a fixed plate 64, the bracket 63 penetrates the side wall of the feeding channel 2 and is slidably connected to the side wall of the feeding channel 2, wherein one end of the bracket 63 located inside the feeding channel 2 is arc-shaped, and a rotating disk 66 capable of squeezing the bracket 63 is fixed at the bottom of the transmission rod 10; When the transmission rod 10 moves in a circular motion, it also drives the turntable 66 to move in a circular motion. When the turntable 66 rotates to the position of the bracket 63, the turntable 66 squeezes the arc-shaped end of the bracket 63, so that the bracket 63 pushes the fixed plate 64, and the fixed plate 64 drives the sealing plate 62 to move horizontally, thereby releasing the sealing state of the sealing plate 62 on the discharge port 61. When the turntable 66 passes the arc-shaped end of the bracket 63, the turntable 66 no longer squeezes the bracket 63, and the fixed plate 64 automatically resets under the action of the second elastic member 65.

[0029] Working principle: When the device is feeding the graphene raw material, the graphene raw material is poured into the feeding channel 2 through the feeding hopper 3, and the rotating part 12 drives the rotating rod 8 to rotate, and the rotating rod 8 drives the baffle 9 to rotate, and the baffle 9 drives the transmission rod 10 to make a circular motion. The baffle 9 drives the transmission rod 10 to make a circular motion and also drives the gear 41 to make a circular motion synchronously. While the gear 41 is making a circular motion, it will mesh with the toothed ring 42 on the inner wall of the feeding channel 2. The meshing of the toothed ring 42 and the gear 41 drives the transmission rod 10 to rotate, so that the stirring rod 11 can rotate while making a circular motion, thereby effectively improving the stirring effect of the graphene raw material inside the feeding channel 2, thereby avoiding the graphene raw material in the feeding channel. 2 internal accumulation and thus cause blockage, so that the graphene raw material can smoothly enter the mixing box 1. In addition, while the rotating rod 8 rotates, it also drives the first slide bar 53 to move in a circle through the baffle 9, and drives the second slide bar 56 to move in a circle through the connecting plate 55. The first slide bar 53 and the second slide bar 56 drive the cutting rope 51 to move in a circle, so that the cutting rope 51 can break up the graphene raw material, and while the cutting rope 51 moves in a circle, the extrusion convex point 59 will squeeze the extrusion block 57, so that the extrusion block 57 pulls the cutting rope 51 downward through the second slide bar 56. When the extrusion block 57 passes over the extrusion convex point 59, the extrusion convex point 59 no longer squeezes the extrusion block 57, and the cutting rope 51 is broken up. The cutting rope 51 automatically resets, and the cycle repeats, so that the cutting rope 51 can move up and down continuously while moving in a circular motion, which can break up the graphene raw materials inside the feeding channel 2, making the graphene raw materials relatively loose, and avoiding the phenomenon of graphene raw materials piling up inside the feeding channel 2, thereby ensuring that the graphene raw materials can smoothly enter the mixing box 1, and the transmission rod 10 also drives the rotating disk 66 to move in a circular motion while the rotating disk 66 rotates to the position of the bracket 63, the rotating disk 66 squeezes the arc-shaped end of the bracket 63, so that the bracket 63 pushes the fixing plate 64, and the fixing plate 64 drives the sealing plate 62 to move horizontally, thereby releasing the sealing plate 62 from the lower The blocked state of the material port 61, when the turntable 66 passes through the arc-shaped end of the bracket 63, the turntable 66 no longer squeezes the bracket 63, and the bracket 63 automatically resets, so that the sealing plate 62 blocks the material port 61, and with the circular motion of the transmission rod 10, the turntable 66 squeezes the remaining brackets 63, so that the remaining material ports 61 can be opened in sequence, so that multiple material ports 61 can be opened in sequence, on the one hand, it can achieve the purpose of intermittent material discharge, thereby avoiding the accumulation of graphene raw materials inside the mixing box 1, ensuring the subsequent mixing effect of the graphene raw materials, and on the other hand, it allows the graphene raw materials to fall evenly into the mixing box 1, further ensuring the subsequent mixing effect of the graphene raw materials.
