Description

Technical Field

[0001] This application relates to the technical field of graphene grinding, and in particular to a grinding device and grinding method for graphene production and processing. Background Technology

[0002] Graphene is a honeycomb-shaped planar thin film formed by carbon atoms in an sp2 hybridization manner. It is a quasi-two-dimensional material with a thickness of only one atomic layer, hence it is also called monolayer graphite. Due to its excellent strength, flexibility, electrical conductivity, thermal conductivity, and optical properties, it has been widely used in physics, materials science, electronics, computer science, aerospace, and other fields. One of the most important properties of graphene is its unique charge carrier characteristics and massless Dirac fermion properties.

[0003] Currently, the mixing of graphene slurry typically involves a grinding process to reduce the volume of solids in the graphene particles or mixture, and to decrease the particle size of the slurry. Existing grinding equipment generally integrates the discharge, grinding, and unloading processes into a single unit. After grinding, operators use an open collection device to collect and transport the graphene slurry at the discharge point, and the grinding equipment must be stopped during this transportation process.

[0004] Regarding the aforementioned technologies, the inventors believe that existing equipment requires the grinding device to be stopped during the process of handling graphene after grinding large quantities of graphene slurry, which prevents continuous output and reduces work efficiency. At the same time, since the operator uses an open collection device to collect the graphene slurry at the discharge point, this process inevitably causes the graphene slurry to splash or overflow, resulting in waste. Summary of the Invention

[0005] In order to achieve continuous output, improve work efficiency, and reduce waste caused by the overflow or splashing of graphene slurry into the collection device, this application provides a grinding device and grinding method for graphene production and processing.

[0006] In a first aspect, this application provides a grinding apparatus for graphene production and processing, employing the following technical solution:

[0007] A grinding apparatus for graphene production and processing, comprising:

[0008] A base, on which an installation frame is mounted;

[0009] Conveyor belt, which is mounted on a base and located within a mounting frame;

[0010] The grinding disc can be mounted on a conveyor belt and can travel with the conveyor belt, and can be removed from the conveyor belt at the end of the conveyor belt;

[0011] The grinding disc is provided with multiple grinding discs, and multiple positioning slots are equally spaced on the conveyor belt. Each grinding disc is equipped with a positioning plate, which can be snapped into the positioning slot.

[0012] A sealing mechanism is installed on the grinding disc to seal the grinding disc during the conveying process.

[0013] The discharge mechanism is mounted on the mounting frame and can move vertically. It can also communicate with the inside of the grinding disc to add graphene slurry to the grinding disc that is running directly below the discharge mechanism.

[0014] The grinding mechanism is mounted on the mounting frame and can move vertically. It can also communicate with the inside of the grinding disc to grind the graphene slurry inside the grinding disc, which runs directly below the grinding mechanism.

[0015] The opening mechanism is installed on the discharge mechanism and the grinding mechanism respectively, and can move vertically with the discharge mechanism or grinding mechanism it is located on. It is used to cooperate with the discharge mechanism or grinding mechanism to open the closing mechanism on the grinding disc before discharge or grinding.

[0016] By adopting the above technical solution, after starting the conveyor belt, the operator sequentially installs the grinding discs on the positioning slots of the conveyor belt, ensuring the closing mechanism corresponds to the opening mechanism. When the conveyor belt delivers the grinding discs directly below the discharge mechanism, the conveyor belt pauses, and the discharge mechanism drives the opening mechanism towards the grinding disc, causing it to open the closing mechanism. After the discharge mechanism engages with the grinding disc, it sprays graphene slurry into the grinding disc. Then, the discharge mechanism drives the opening mechanism to reset, and the closing mechanism automatically resets to close the grinding disc, while the conveyor belt continues to deliver the grinding discs. When the conveyor belt delivers the grinding discs directly below the grinding mechanism, the conveyor belt pauses, and the grinding mechanism drives the opening mechanism to open the grinding disc. The initiating mechanism moves towards the grinding disc and drives the opening mechanism to open the closing mechanism. After the grinding mechanism engages with the grinding disc, it grinds the graphene slurry inside the grinding disc. Then, the grinding mechanism drives the opening mechanism to reset, and the closing mechanism resets itself to close the grinding disc. The conveyor belt continues to transport the grinding disc until it is sent out of the conveyor belt and transported for collection. During the above process, the feeding mechanism and the grinding mechanism can continuously discharge and grind the material inside the grinding disc, achieving continuous discharge and improving work efficiency. At the same time, the grinding disc can be closed by the closing mechanism during the conveying and transporting process, reducing the waste caused by the overflow or splashing of graphene slurry into the collection device.

[0017] Optionally, each grinding disc is symmetrically equipped with two closing mechanisms. Each closing mechanism includes a closing disc, an abutment block, a flipping rod, a slider, a telescopic rod, a telescopic cylinder, a telescopic spring, and a connecting block. The closing disc is located at the opening of the grinding disc, and the two closing discs on the same grinding disc abut against each other and completely close the opening of the grinding disc. The connecting block is fixed to the grinding disc body. The telescopic cylinder is hinged to the connecting block. The telescopic spring is installed in the sleeve and is in the extended state. The telescopic rod slides in the telescopic cylinder and its end is fixed to the telescopic spring. The abutment block abuts against the arc-shaped edge of the corresponding grinding disc and can abut against the grinding disc body. The flipping rod is fixed to the abutment block. The flipping rod is an L-shaped rod. The slider is slidably embedded in the lower part of the flipping rod, and the telescopic rod is hinged to the slider.

[0018] The mechanism involves pressing down the flipping rod, causing the slider to slide towards the abutment block, and the telescopic rod to press down the telescopic spring, which in turn causes the abutment block to open the closed plate that is fastened to the grinding disc.

[0019] Optionally, a positioning crank is installed on the abutment block, and a corresponding groove is opened on the grinding disc body. The positioning crank can be slidably inserted into the groove of the grinding disc body.

[0020] By adopting the above technical solution and setting the positioning crank, the horizontal displacement of the abutment block after it abuts the grinding disc is reduced, thereby enhancing the stability of the enclosed mechanism during handling and transmission.

[0021] Optionally, each enclosure also includes a handle mounted on a tilting lever for the operator to move the grinding disc.

[0022] Optionally, the discharge mechanism includes a second elevator, a first enclosed cylinder, a pump, a discharge pipe, a feeding ring pipe, and a nozzle. The second elevator is mounted on the mounting frame and located on one side of the initial end of the conveyor. The first enclosed cylinder is mounted on the second elevator and can move vertically with the second elevator, and can be closed and engaged with the grinding disc located directly below. The pump is mounted on the first enclosed cylinder and can be connected to an external storage device. The feeding ring pipe is added inside the first enclosed cylinder. The discharge pipe passes through the first enclosed cylinder and is connected to the enclosed ring pipe and the pump respectively. The nozzle is circumferentially fixedly connected to the discharge ring pipe and is used to spray graphene slurry into the grinding disc.

[0023] Optionally, the grinding mechanism includes a third lift, a second enclosed cylinder, a fourth lift, a lifting plate, a rotating motor, and a grinding cone. The third lift is mounted on the mounting frame and located on one side of the conveying end. The second enclosed cylinder is mounted on the third lift and can move vertically with the third lift, and can be closed and fastened with the grinding disc located directly below. The fourth lift is mounted on the second enclosed cylinder, and the lifting rod of the fourth lift passes through and enters the second enclosed cylinder. The lifting plate is located inside the second enclosed cylinder, and its upper sidewall is fixed to the end of the lifting rod of the fourth lift. The lifting plate can move vertically inside the second enclosed cylinder with the lifting rod of the fourth lift. The rotating motor is mounted at the center of the upper sidewall of the lifting plate, and the rotating shaft of the rotating motor passes through the lifting plate. The grinding cone is located inside the second enclosed cylinder and is fixedly connected to the rotating shaft of the rotating motor.

[0024] The straight-line distance between the centers of the first and second closed cylinders is equal to the straight-line distance between the centers of the two adjacent positioning slots.

[0025] Optionally, both the first and second sealing cylinders are equipped with sealing sleeves. When the first or second sealing cylinder is engaged with the grinding disc, the sealing sleeves will circumferentially enclose the opening of the grinding disc.

[0026] By adopting the above technical solution, the sealing sleeve improves the overall sealing performance of the first and second sealing cylinders when they are connected and engaged with the grinding disc, reducing the occurrence of graphene slurry overflow during material discharge and grinding.

[0027] Optionally, the opening mechanism includes a first lifting mechanism, a connecting collar, and a stop plate. The first lifting mechanism is circumferentially fixed on the first closed cylinder and the second closed cylinder respectively. The connecting collar is sleeved on the lower part of the first closed cylinder and the second closed cylinder respectively, and the connecting collar is fixed to the lifting rod of the corresponding first lifting mechanism and can move in the vertical direction. The stop plate is installed on the lower side wall of the connecting collar and corresponds one-to-one with the position of the flipping rod symmetrically arranged on the grinding disc.

[0028] Optionally, a placement platform and a guard plate are installed on the base. The placement platform and the guard plate are both located on the side of the base located at the end of the conveyor belt, and are used to temporarily place and collect the grinding discs that are carried out from the conveyor belt.

[0029] Secondly, this application provides a grinding method for a grinding apparatus used in graphene production and processing, employing the following technical solution:

[0030] A grinding method for a grinding apparatus used in graphene production and processing includes the following steps:

[0031] S1. Start the conveyor belt, and after the positions of the closing mechanism and each of the opening mechanisms on the grinding disc are aligned, place the grinding discs in sequence, and wait for the grinding discs to be collected at the placement table.

[0032] S2. When the grinding disc moves to the bottom of the discharge mechanism, the conveying stops, the discharge mechanism gradually engages with the grinding mechanism, and the opening mechanism is driven to open the closing mechanism on the grinding disc.

[0033] S3. The discharge mechanism sprays graphene slurry into the grinding disc that it is engaged with. After the discharge is completed, the discharge mechanism gradually separates from the grinding disc and drives the opening mechanism to separate from the closing mechanism. After the closing mechanism automatically resets, it continues to convey.

[0034] S4. When the grinding disc moves to the bottom of the grinding mechanism, the conveying stops, the discharge mechanism gradually engages with the grinding mechanism, and drives the opening mechanism to open the closing mechanism on the grinding disc.

[0035] S5. The grinding mechanism grinds the graphene slurry in the grinding disc that is engaged with it. After grinding is completed, the grinding mechanism gradually separates from the grinding disc and drives the opening mechanism to separate from the closing mechanism. After the closing mechanism automatically resets, it continues to convey.

[0036] S6. The operator moves and collects the grinding discs that have been transferred to the placement table;

[0037] S7. Repeat S2-S6 until all the graphene slurry in this batch has been ground.

[0038] In summary, this application includes at least one of the following beneficial technical effects:

[0039] 1. After starting the conveyor belt, the operator sequentially installs the grinding discs into the positioning slots of the conveyor belt, ensuring the closing mechanism aligns with the opening mechanism. When the conveyor belt delivers the grinding discs directly below the discharge mechanism, the conveyor belt pauses. The discharge mechanism drives the opening mechanism towards the grinding disc, opening the closing mechanism and allowing it to engage with the grinding disc, spraying graphene slurry into the disc. The discharge mechanism then drives the opening mechanism to reset, and the closing mechanism automatically resets to close the grinding disc. The conveyor belt continues conveying. When the conveyor belt delivers the grinding discs directly below the grinding mechanism, the conveyor belt pauses, and the grinding mechanism drives the opening mechanism towards the grinding disc... The grinding disc moves, driving the opening mechanism to open the closing mechanism. After the grinding mechanism engages with the grinding disc, it grinds the graphene slurry inside the grinding disc. Then, the grinding mechanism drives the opening mechanism to reset, and the closing mechanism automatically resets and closes the grinding disc. The conveyor belt continues to transport the grinding disc until it is sent out of the conveyor belt and transported for collection. During the above process, the feeding mechanism and the grinding mechanism can continuously discharge and grind the material inside the grinding disc, achieving continuous discharge and improving work efficiency. At the same time, the grinding disc can be closed by the closing mechanism during the conveying and transporting process, reducing the waste caused by the overflow or splashing of graphene slurry into the collection device.

[0040] 2. The positioning crank reduces the horizontal displacement of the abutment block after it abuts the grinding disc, thus enhancing the stability of the enclosed mechanism during handling and transmission.

[0041] 3. The sealing sleeve design improves the overall sealing performance of the first and second sealing cylinders when they are engaged with the grinding disc, reducing the occurrence of graphene slurry overflow during discharge and grinding. Attached Figure Description

[0052] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0053] This application discloses a grinding apparatus for graphene production and processing.

[0054] refer to Figure 1 A grinding device for graphene production and processing includes a base 1, a conveyor belt 2, a sealing mechanism 4, an opening mechanism 5, a discharge mechanism 6, a grinding mechanism 7, and several grinding discs 3. A mounting frame 11 is fixedly installed on the upper part of the base 1, and the upper part of the mounting frame 11 is a frame plate. The conveyor belt 2 is installed on the base 1 and passes through the mounting frame 11. The grinding discs 3 can be sequentially installed on the conveyor belt 2. The sealing mechanism 4 is installed on the grinding discs 3 to keep them closed during conveying or handling. The discharge mechanism 6 and the grinding mechanism 7 are respectively installed on the frame plate of the mounting frame 11. The opening mechanism 5 is respectively installed on the discharge mechanism 6 and the grinding mechanism 7. The opening mechanism 5 is used to cooperate with the discharge mechanism 6 or the grinding mechanism 7 to open the sealing mechanism 4 on the grinding discs 3. The discharge mechanism 6 is used to spray graphene slurry into the grinding discs 3, and the grinding mechanism 7 is used to grind the graphene slurry in the grinding discs 3.

[0055] refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, only four grinding discs 3 are shown for illustration. A positioning plate 31, which is a cubic plate, is fixedly installed on the lower side wall of each grinding disc 3. Positioning grooves 21 are formed on the surface of the conveyor belt 2, and these grooves are equidistant along the length of the conveyor belt 2. The positioning plate 31 can be fitted into the positioning groove 21. The grinding discs 3 are positioned and installed on the conveyor belt 2 through the connection between the positioning plate 31 and the positioning groove 21.

[0056] A placement platform 13 and a protective plate 14 are fixedly installed on the base 1. The placement platform 13 is horizontally arranged along the length of the base 1. One end of the placement platform 13 is fixedly connected to the side wall of the base 1 at the end of the conveying process, and the upper side wall of the placement platform 13 is horizontal to the upper side wall of the base 1. The protective plates 14 are located on both sides of the placement platform 13 along the length of the base 1, and the protective plates 14 are fixedly connected to the adjacent side walls of the base 1 and the placement platform 13.

[0057] When the grinding disc 3 installed on the conveyor belt 2 travels above the base 1 to the end of the conveyor, the positioning plate 31 gradually separates from the positioning groove 21, so that the grinding disc 3 gradually falls on the upper part of the placement table 13, and the operator can transport and collect the grinding disc 3 that has completely fallen to the placement table 13.

[0058] refer to Figure 1A central control console 12 is installed on the base 1, and the central control console 12 is embedded in the vertical side wall of the base 1 along its length. The central control console 12 is electrically connected to the conveyor belt 2, the discharge mechanism 6 and the grinding mechanism 7 respectively, and is used to control the start and stop of the conveyor belt 2 and the conveying speed, the connection between the discharge mechanism 6 and the grinding disc 3 and the discharge amount, the connection between the grinding mechanism 7 and the grinding disc 3, and the degree of grinding of the graphene slurry.

[0059] refer to Figure 1 , Figure 3 and Figure 4 Each grinding disc 3 is equipped with a sealing mechanism 4, which are symmetrically arranged above the grinding disc 3, with the axis of symmetry running along the diameter of the grinding disc 3, which is horizontal to the width of the base 1. In this embodiment, each sealing mechanism 4 located on the side of the axis of symmetry includes a sealing disc 41, two abutting blocks 42, two flipping rods 43, two sliders 44, two telescopic rods 45, two telescopic cylinders 46, and two telescopic springs 47. The sealing disc 41 is placed at the opening above the grinding disc 3, and the grinding discs 3 on both sides of the sealing mechanism 4 can abut against each other, completely sealing the opening above the grinding disc 3. The abutting blocks 42, flipping rods 43, sliders 44, telescopic rods 45, telescopic cylinders 46, and telescopic springs 47 in the sealing mechanism 4 located on one side of the axis of symmetry are evenly divided into two groups and are symmetrically arranged along the length axis of the base 1.

[0060] The abutment block 42 is arranged vertically and close to the length axis of the base 1. The upper part of the abutment block 42 is fixedly connected to the side wall of the adjacent closed disk 41, and the lower part abuts against the adjacent grinding disk 3. The flipping rods 43 are all L-shaped rods, with the L-shaped openings facing away from the ground. The overall length of the flipping rod 43 is the same as the length of the base 1. One end of the flipping rod 43 is fixedly connected to the upper part of the side wall of the abutment block 42 away from the closed disk 41, and a curved angle is provided at the inner bend of the L-shape of the flipping rod 43. Each closing mechanism 4 is provided with a handle 49. In this embodiment, the handle 49 is a rod-shaped structure. The handle 49 is arranged along the width of the base 1 and is located between the two flipping rods 43 of the corresponding closing mechanism 4. Both ends of the handle 49 are fixedly connected to the upper side wall of the adjacent flipping rod 43, respectively.

[0061] The slider 44 is slidably engaged on the lower horizontal side wall of the corresponding flipping rod 43, and one end of the telescopic rod 45 is hinged to the lower side wall of the corresponding slider 44 via a pivot pin. The connecting block 48 is fixed on the grinding disc 3 and located directly below the corresponding connecting block 48. One end of the telescopic cylinder 46 is hinged to the side wall of the connecting block 48 away from the grinding disc 3 via a pivot pin, and the telescopic rod 45 is slidably inserted into the corresponding telescopic cylinder 46. The telescopic spring 47 is installed inside the telescopic cylinder 46, with one end fixedly connected to the inner wall of the bottom of the telescopic cylinder 46 and the other end fixedly connected to the end face of the telescopic rod 45 extending into the telescopic cylinder 46. When the closed disc 41 is fastened onto the grinding disc 3, the telescopic spring 47 is always in a relaxed state.

[0062] Each of the closed discs 41 is provided with a sealing ring 411. The sealing ring 411 is fixed to the lower edge of the closed disc 41. The sealing rings 411 on the two closed discs 41 on the same grinding disc 3 can abut against each other on the close parts, and the other part can abut against the circumference of the opening of the grinding disc 3.

[0063] Each abutment block 42 is equipped with a positioning crank 421. The positioning crank 421 is fixed at the part where the abutment block 42 abuts against the grinding disc 3. The grinding disc 3 has a sliding groove, and the positioning crank 421 can be slidably inserted into the sliding groove.

[0064] When the closing mechanism 4 needs to open on the grinding disc 3, the flipping rod 43 is pressed downwards and flips, causing the abutment block 42 to drive the closing disc 41 to flip upwards, thus opening the opening of the grinding disc 3. At this time, the slider 44 moves toward the abutment block 42, causing the telescopic rod 45 and the telescopic cylinder 46 to flip downwards as a whole, and the telescopic rod 45 presses down the telescopic spring 47. When the closing mechanism 4 needs to close and seal the grinding disc 3, it is only necessary to disconnect the pressure on the flipping rod 43, allowing the compression spring to return to its original position, driving the remaining components to reset.

[0065] refer to Figure 1 , Figure 5 and Figure 6The discharge mechanism 6 is located on the side of the mounting frame 11 near the initial end of the conveyor. The discharge mechanism 6 includes a second elevator 61, a first enclosed cylinder 62, a feeding ring pipe 65, two suction pumps 63, two discharge pipes 64, and several nozzles 66. The second elevator 61 is vertically oriented and fixedly mounted on the frame plate on the upper part of the mounting frame 11, located on the longitudinal axis of the base 1. The opening of the first enclosed cylinder 62 faces downwards, and the center of its bottom is fixedly connected to the end face of the lifting rod of the second elevator 61. It can move vertically with the second elevator 61 and engage with the grinding disc 3 located directly below it. The suction pumps 63 are symmetrically arranged on both sides of the lifting rod of the second elevator 61 along the length of the base 1. The suction pumps 63 are fixed to the upper side wall of the bottom of the first enclosed cylinder 62 and can be connected to external discharge equipment. Two vents are provided on the first enclosed cylinder 62, symmetrically arranged on both sides of the lifting rod of the second elevator 61 along the length of the base 1, and located between the material pumps 63. The feeding ring pipe 65 is a ring-shaped pipe structure, horizontally arranged and located inside the first enclosed cylinder 62, and is installed inside the first enclosed cylinder 62 by a bracket. The discharge pipe 64 corresponds one-to-one with the material pump 63, with one end of the discharge pipe 64 connected to the material pump 63, and the other end passing through the first enclosed cylinder 62 and connected to the feeding ring pipe 65. The nozzles 66 are all circumferentially and equidistantly arranged below the feeding ring pipe 65, and are all connected to the feeding ring pipe 65.

[0066] refer to Figure 1 , Figure 7 and Figure 8The grinding mechanism 7 is located on the side of the mounting frame 11 near the end of the conveyor. The grinding mechanism 7 includes a third lift 71, a second enclosed cylinder 72, a lifting plate 74, a rotating motor 75, a grinding cone 76, and two fourth lifts 73. The third lift 71 is vertically oriented and fixedly mounted on the frame plate on the upper part of the mounting frame 11, located on the length axis of the base 1. The opening of the second enclosed cylinder 72 faces downwards, and the center of its bottom is fixedly connected to the end face of the lifting rod of the third lift 71. It can move vertically with the third lift 71 and can be closed and engaged with the grinding disc 3 located directly below. The fourth lifts 73 are symmetrically arranged on both sides of the lifting rod of the third lift 71 along the length of the base 1. The fourth lifts 73 are fixed to the upper side wall of the bottom of the second enclosed cylinder 72, and their lifting rods penetrate and enter the second enclosed cylinder 72. A lifting plate 74 is horizontally positioned within the second enclosed cylinder 72, with its upper sidewall fixed to the end of the lifting rod of the fourth lifting machine 73. The lifting plate 74 can move vertically within the second enclosed cylinder 72 along with the lifting rod of the fourth lifting machine 73. A rotary motor 75 is installed at the center of the upper sidewall of the lifting plate 74, with its rotating shaft vertically positioned and passing through the lifting plate 74. Each fourth lifting machine 73 is equipped with a limit ring 731, which is fixedly fitted onto the lifting rod of the fourth lifting machine 73 within the second enclosed cylinder 72. The distance from the limit ring 731 to the lifting plate 74 is equal to the height of the rotary motor 75. A grinding cone 76 is located within the second enclosed cylinder 72 and is fixedly connected to the rotating shaft of the rotary motor 75.

[0067] The straight-line distance between the centers of the bottoms of the first closed cylinder 62 and the second closed cylinder 72 is the same as the straight-line distance between the centers of the two adjacent positioning slots 21. When the second closed cylinder 72 engages with the grinding disc 3 directly below it, the grinding cone 76 descends with the fourth elevator 73 and comes into contact with the graphene slurry. The rotating motor 75 drives the grinding cone 76 to grind the graphene slurry. At this time, the corresponding grinding disc 3 is waiting to be sprayed with graphene slurry directly below the discharge mechanism 6.

[0068] refer to Figure 1 , Figure 5 and Figure 7 The opening mechanism 5 includes a first lifting mechanism 51, a connecting collar 52, and an abutment plate 53. The first lifting mechanism 51 is circumferentially fixed on the first closed cylinder 62 and the second closed cylinder 72 respectively. The connecting collar 52 is respectively sleeved on the lower part of the first closed cylinder 62 and the second closed cylinder 72, and the connecting collar 52 is fixed to the lifting rod of the corresponding first lifting mechanism 51 and can move in the vertical direction. The abutment plate 53 is installed on the lower side wall of the connecting collar 52 and corresponds one-to-one with the position of the flipping rod 43 symmetrically arranged on the grinding disc 3. The lower end of the abutment plate 53 is opened with an arc so that when the abutment plate 53 presses down on the flipping plate, it passes through the L-shaped inner bend more smoothly.

[0069] refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 Both the first sealing cylinder 62 and the second sealing cylinder 72 are equipped with sealing sleeves 8, and the sealing sleeves 8 are located inside the connecting collar 52. When the first sealing cylinder 62 or the second sealing cylinder 72 is engaged with the grinding disc 3, the sealing sleeve will circumferentially enclose the opening of the grinding disc 3 that is nearby.

[0070] This application also discloses a grinding method for a grinding apparatus used in graphene production and processing.

[0071] Includes the following steps:

[0072] S1. The operator starts the conveyor belt 2 and inputs the instruction parameters of conveying speed and start / stop time into the central control console 12. After the vertical projection of the handle 49 in the closing mechanism 4 on the grinding disc 3 and the abutment plate 53 in each opening mechanism 5 is horizontal, the grinding disc 3 is placed on the conveyor belt 2 in sequence, so that the positioning plate 31 of the grinding disc 3 is engaged with the positioning groove 21 of the conveyor belt 2, and the grinding disc 3 waits at the end of the placement table 13 to collect the ground graphene slurry.

[0073] S2. After the grinding disc 3 is moved sequentially to the underside of the discharge mechanism 6 via the conveyor belt 2, the central control console 12 automatically controls the conveyor belt 2 to stop conveying and controls the discharge mechanism 6 to move towards the grinding disc 3 directly below it and gradually engage the two. At the same time, the discharge mechanism 6 drives the opening mechanism 5 installed on it to gradually open the closing mechanism 4 on the corresponding grinding disc 3.

[0074] S3, the central control console 12 controls the discharge mechanism 6 to spray graphene slurry into the grinding disc 3 that is engaged with it. After the discharge is completed, the discharge mechanism 6 gradually separates from the grinding disc 3 and drives the opening mechanism 5 to separate from the closing mechanism 4. The closing mechanism 4 automatically resets and closes the opening of the grinding disc 3. The central control console 12 automatically controls the conveyor belt 2 to continue conveying.

[0075] S4. When the grinding disc 3 is moved directly below the discharge mechanism 6, repeat steps S2-S3.

[0076] S5. When the grinding disc 3, which is continuously conveyed by the discharge mechanism 6, runs to the ground directly below the grinding mechanism 7, the central control panel 12 automatically controls the conveyor belt 2 to stop conveying and causes the discharge mechanism 6 to move towards the grinding disc 3 directly below it and gradually engage the two. At the same time, the grinding mechanism 7 drives the opening mechanism 5 installed on it to gradually open the closing mechanism 4 on the corresponding grinding disc 3.
