Description

Technical Field

[0001] The utility model relates to the field of graphene copper pretreatment preparation, in particular to a graphene copper pretreatment preparation device. Background Art

[0002] With the development of electronic integration technology, the performance of pure copper or copper alloys is often far from meeting the current needs. Traditional alloy additions or particle additions can increase its strength, but often lead to a significant decrease in its main electrical and thermal conductivity. Currently, graphene has become an ideal filler for copper-based composite materials due to its excellent comprehensive properties.

[0003] Chinese patent publication number CN210134161U discloses a graphene copper powder production device, comprising a heating furnace, a reaction chamber, a feeding device, a material transport device, a material collection device, and a rotating device. The feeding device, material transport device, and material collection device are all fixedly connected to the reaction chamber, which is provided with an air inlet and an air outlet. The utility model utilizes an inclined material transport device and a rotating device to allow the material to flow and slide through the high-temperature zone under the action of gravity, thereby preventing the material from sticking at high temperatures.

[0004] After the graphene copper preparation device of the above patent completes the heating preparation work of the graphene copper powder, the graphene copper powder is discharged from the discharge port of the preparation device. However, the discharge port is provided with a discharge speed control structure considering that the temperature of the graphene copper powder after heating is relatively high, resulting in uncontrollable discharge speed of the graphene copper powder. Utility Model Content

[0005] The purpose of the utility model is to provide a graphene copper pretreatment preparation device, which mainly slows down the feeding speed of the graphene copper powder prepared after screening when it falls from the top of the feeding tube to the feeding port of the feeding tube by arranging a slow-down plate with an inclined angle in the feeding tube. In addition, no electric mechanical structure is used, so there is no possibility that the graphene powder enters the interior of the electric machine and causes the circuit board inside the electric machine to be contaminated with graphene copper powder, resulting in a short circuit of the circuit board and the possibility of breakdown of the circuit board, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a graphene copper pretreatment preparation device, comprising a feed pipe, a buffer plate is provided on the inner wall of the feed pipe, and a feed port is provided, the feed port is provided on the feed pipe, the upper end of the feed pipe is provided with a support block, a linear vibrating screen is provided on the support block, a feed port is provided on the linear vibrating screen, a pure material feed pipe is provided at the lower end of the linear vibrating screen, the pure material feed pipe extends into the feed pipe, an impurity discharge port is provided on the linear vibrating screen, a collecting tank is provided on the impurity discharge port, an impurity discharge pipe is provided at the lower end of the collecting tank, a fixed block is provided on the outer surface of the feed pipe, and a hydraulic cylinder is provided on the fixed block.

[0007] Preferably, a servo motor is provided on the outer surface of the discharge pipe, and the fixed end of the servo motor is bolted to the discharge pipe.

[0008] Preferably, a connecting arm is provided on the output end of the servo motor, and the connecting arm is bolted to the output end of the servo motor.

[0009] Preferably, the connecting arm is provided with a rotary bearing on one end away from the servo motor, and the inner ring of the rotary bearing is bolted to the connecting arm.

[0010] Preferably, a rolling roller is provided on the outer ring of the rotary bearing, and the rolling roller is rotatably connected to the rotary bearing.

[0011] Preferably, a clamping fixing block is provided at the lower end of the fixed end of the hydraulic cylinder.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model is provided with a slow-down plate with an inclined angle in the discharge tube, which mainly plays the role of slowing down the discharge speed of the graphene copper powder when the screened graphene copper powder falls from the top of the discharge tube to the discharge port of the discharge tube, and no electric mechanical structure is used, so there is no possibility that the graphene powder enters the interior of the electric machine and causes the circuit board inside the electric machine to be contaminated by the graphene copper powder, resulting in a short circuit of the circuit board and the breakdown of the circuit board. It effectively avoids the problem that the existing graphene copper preparation device discharges the graphene copper powder from the discharge port of the preparation device after completing the heating preparation work of the graphene copper powder, but the discharge port is provided with a discharge speed control structure due to the high temperature of the heated graphene copper powder, resulting in the uncontrollable discharge speed of the graphene copper powder.

Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0020] In order to solve the problem in the prior art that after the graphene copper preparation device completes the heating preparation work of the graphene copper powder, the graphene copper powder is discharged from the discharge port of the preparation device, but the discharge port is provided with a discharge speed control structure due to the high temperature of the heated graphene copper powder, resulting in an uncontrollable discharge speed of the graphene copper powder, this embodiment provides the following technical solutions:

[0021] A graphene copper pretreatment preparation device includes a feeding pipe 1, a buffer plate 17 is provided on the inner wall of the feeding pipe 1, and a feeding port 12 is provided on the feeding pipe 1. The feeding port 12 is provided on the feeding pipe 1, and a support block 2 is provided at the upper end of the feeding pipe 1. A linear vibrating screen 3 is provided on the support block 2. A feed port 4 is provided on the linear vibrating screen 3. A pure material feeding pipe 8 is provided at the lower end of the linear vibrating screen 3. The pure material feeding pipe 8 extends into the feeding pipe 1, and an impurity discharge port 5 is provided on the linear vibrating screen 3. A collecting tank 6 is provided on the impurity discharge port 5, and an impurity discharge pipe 7 is provided at the lower end of the collecting tank 6. A fixing block 9 is provided on the outer surface of the feeding pipe 1, a hydraulic cylinder 10 is provided on the fixing block 9, and a clamping fixing block 11 is provided at the lower end of the fixed end of the hydraulic cylinder 10;

[0022] In this embodiment, please refer to Figures 1-4, the staff first puts the graphene copper powder into the feeding port 4 opened on the linear vibrating screen 3, the linear vibrating screen 3 screens out the impurities in the graphene copper powder, and discharges the impurities from the impurity discharge port 5 into the collecting tank 6, and then the screened graphene copper powder enters the discharge pipe 1 from the pure material discharge pipe 8, and the graphene copper powder contacts the buffer plate 17 provided on the inner wall of the discharge pipe 1. Because the buffer plate 17 itself has an inclined angle, when the graphene copper powder accumulates to a certain amount on the buffer plate 17, it will naturally fall down from the buffer plate 17 and be discharged from the discharge port 12 of the discharge pipe 1. The staff can use the clamping fixing block 11 to fix the discharge pipe 1 on the conveyor belt, which is convenient for laying the filtered graphene copper powder on the material;

[0023] In this embodiment, please refer to Figures 1-4 A servo motor 13 is provided on the outer surface of the discharge tube 1, and the fixed end of the servo motor 13 is bolted to the discharge tube 1, and a connecting arm 14 is provided on the output end of the servo motor 13, and the connecting arm 14 is bolted to the output end of the servo motor 13. A rotating bearing 15 is provided on the end of the connecting arm 14 away from the servo motor 13, and the inner ring of the rotating bearing 15 is bolted to the connecting arm 14, and a rolling roller 16 is provided on the outer ring of the rotating bearing 15, and the rolling roller 16 is rotatably connected to the rotating bearing 15. The arrangement of the rolling roller 16 can drive the connecting arm 14 to rotate when the graphene copper powder is laid on the material, and the rolling roller 16 is lowered to make it contact with the material, so as to flatten the graphene copper powder laid on the material and make it evenly laid.

[0024] Working principle: The staff first puts the graphene copper powder into the feed port 4 on the linear vibrating screen 3. The linear vibrating screen 3 screens out the impurities in the graphene copper powder and discharges the impurities from the impurity discharge port 5 into the collection tank 6. Then the screened graphene copper powder enters the feed pipe 1 from the pure material feed pipe 8. The graphene copper powder contacts the buffer plate 17 provided on the inner wall of the feed pipe 1. Because the buffer plate 17 itself has an inclined angle, when the graphene copper powder accumulates on the buffer plate 17, the graphene copper powder When a certain amount is reached, it will naturally fall down from the buffer plate 17 and be discharged from the discharge port 12 of the discharge pipe 1. The staff can use the clamping fixing block 11 to fix the discharge pipe 1 on the conveyor belt, so as to facilitate the laying of the filtered graphene copper powder on the material. The setting of the rolling roller 16 can be such that when the graphene copper powder is laid on the material, the servo motor 13 drives the connecting arm 14 to rotate, and the rolling roller 16 is lowered to make it contact with the material, and the graphene copper powder laid on the material is flattened to make it evenly laid.
