Description

Technical Field

[0001] This utility model belongs to the field of graphite tableting technology, and in particular relates to a powder graphite tableting device. Background Technology

[0002] Compression molding is the most common method for forming graphite. The process involves drying graphite powder and mixing it with a binder (such as phenolic resin or asphalt) in a specific ratio. This mixture is then placed in a mold and pressure is applied to obtain the desired shape. This method is low-cost and suitable for mass production of simple-shaped graphite products. It is a commonly used technology for preparing graphite electrodes, graphite crucibles, sealing rings, and battery negative electrode materials, and is widely used in metallurgy, machinery, electronics, and new energy fields. However, existing technologies suffer from agglomeration in the mixture. Large agglomerates entering the mold affect the pressing effect, and the lack of equipment for uniform material distribution after material is added to the mold leads to uneven material distribution, resulting in uneven thickness, rough surfaces, or defects in the pressed graphite sheets, thus affecting the quality of the graphite sheets. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a powder graphite tablet forming device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A powder graphite tablet forming device includes a worktable and a support on the worktable, wherein a lower mold is provided on the worktable; a cylinder is provided on the top of the support, and the output end of the cylinder is connected to an upper mold, wherein the upper mold is located above the lower mold; The workbench is equipped with a rotary lifting assembly, which is connected to a uniform material cylinder. The uniform material cylinder is used to feed material into the lower mold and move the uniform material cylinder to the outside of the lower mold after feeding is completed. The uniform feed cylinder is equipped with a grid plate, and a stirring shaft is rotatably mounted at the bottom of the grid plate. A stirring rod is mounted on the stirring shaft. A mounting frame is provided on one side of the uniform material cylinder, and a rotating shaft is rotatably mounted on the mounting frame. A push rod is provided on the rotating shaft. The mounting bracket is equipped with a spring, one end of which is connected to a push plate. The upper side of the push plate is provided with a striking ball, which contacts the side of the uniform material cylinder.

[0005] Furthermore, a drive wheel is rotatably provided at the bottom of the mesh plate, the drive wheel is coaxially connected to the stirring shaft, and is located at the top of the stirring shaft; Another drive wheel is provided on the outside of the uniform material cylinder, and the two drive wheels are connected by a synchronous belt. A first motor is provided on the outside of the uniform material cylinder, and the first motor is connected to the transmission wheel on the outside of the uniform material cylinder.

[0006] Furthermore, a protective cover is provided at the bottom of the grid plate, and one end of the protective cover passes through the side of the uniform material cylinder; Both the transmission wheel and the first motor are housed inside a protective cover.

[0007] Furthermore, the output end of the first motor is connected to a drive bevel gear, which is coaxially arranged with one of the transmission wheels; The mounting bracket is provided with a driven bevel gear, and the driving bevel gear is meshed with the driven bevel gear; The rotating shaft is coaxially connected to the driven bevel gear.

[0008] Furthermore, the spring is provided with a telescopic rod, and the two ends of the telescopic rod are respectively connected to the mounting bracket and the push plate.

[0009] Furthermore, the rotary lifting assembly includes a threaded rod, which is rotatably mounted on the worktable, and the top of the threaded rod is rotatably connected to the bracket; A control rod is provided on the outside of the threaded rod, and the control rod is threadedly connected to the threaded rod; One end of the control rod is connected to the outside of the uniform material cylinder; The bracket is equipped with a second motor, and the output end of the second motor is connected to the threaded rod.

[0010] Furthermore, the worktable is provided with a first stop bar, and when the material equalizing cylinder is located in the lower mold, the first stop bar abuts against the side of the control rod.

[0011] Furthermore, the workbench is provided with a second stop bar, and the height of the second stop bar is lower than that of the first stop bar; When the material distribution cylinder is located in the lower mold, the second stop is located on the other side of the control rod away from the first stop and abuts against the side of the control rod.

[0012] Furthermore, a guide plate is provided on one side of the top of the uniform material cylinder, and the guide plate is inclined.

[0013] This utility model has the following beneficial effects: 1. The second motor drives the threaded rod to rotate, and the control rod drives the material distribution cylinder to rotate synchronously with the threaded rod. When the material distribution cylinder moves to the top of the lower mold, one side of the control rod abuts against the first baffle. The threaded rod continues to rotate, and the control rod drives the material distribution cylinder to move down until the lower end of the material distribution cylinder is inside the lower mold, thus realizing the movement of the material distribution cylinder, which is convenient and quick.

[0014] 2. The first motor drives the transmission wheel to rotate, and the synchronous belt and transmission wheel drive the stirring shaft to rotate. The stirring rod stirs the graphite powder that has passed through the mesh plate and entered the lower mold, so that the material is evenly distributed in the lower mold, thereby making the mold pressing quality uniform.

[0015] 3. When the first motor rotates, it drives the driven bevel gear to rotate through the active bevel gear, thereby driving the rotating shaft to rotate. When the push rod of the rotating shaft rotates to the side of the push plate, it pushes the push plate and the striking ball away from the outside of the uniform material cylinder and squeezes the spring. When the push rod and the push plate are no longer in contact, the elastic force of the spring causes the push plate to drive the striking ball to strike the side of the uniform material cylinder, which accelerates the feeding of the uniform material cylinder.

[0022] like Figure 1-5 As shown, a powder graphite tablet forming device includes a worktable 1 and a support 11 disposed on the worktable 1. A lower mold 2 is disposed on the worktable 1. A cylinder 21 is disposed on the top of the support 11. The output end of the cylinder 21 is connected to an upper mold 22, which is disposed above the lower mold 2. The mixed graphite powder is fed into the lower mold 2. The cylinder 21 drives the lower mold 2 to move into the upper mold 22, applying pressure to the graphite powder to form the tablet and complete the tablet forming operation.

[0023] The workbench 1 is equipped with a rotary lifting assembly 3, which is connected to a material distribution cylinder 4. The assembly 3 is used to feed the material distribution cylinder 4 into the lower mold 2 and, after feeding, to move the material distribution cylinder 4 to the outside of the lower mold 2. The rotary lifting assembly 3 includes a threaded rod 31, which is rotatably mounted on the workbench 1, and its top is rotatably connected to a support 11. A control rod 33 is provided on the outside of the threaded rod 31, and is threadedly connected to the threaded rod 31. One end of the control rod 33 is connected to the outer side of the material distribution cylinder 4. Side connection; a second motor 32 is provided on the bracket 11, and the output end of the second motor 32 is connected to the threaded rod 31. A first stop rod 34 is provided on the worktable 1. When the material equalizing cylinder 4 is located in the lower mold 2, the first stop rod 34 abuts against the side of the control rod 33. A second stop rod 35 is provided on the worktable 1, and the height of the second stop rod 35 is lower than that of the first stop rod 34. When the material equalizing cylinder 4 is located in the lower mold 2, the second stop rod 35 is located on the other side of the control rod 33 away from the first stop rod 34, and abuts against the side of the control rod 33. When it is necessary to feed material into the lower mold 2, the second motor 32 drives the threaded rod 31 to rotate. At this time, the height of the control rod 33 is not obstructed by the first stop 34 and the second stop 35. The control rod 33 drives the material distribution cylinder 4 to rotate synchronously with the threaded rod 31. When the material distribution cylinder 4 moves above the lower mold 2, one side of the control rod 33 abuts against the first baffle. The threaded rod 31 continues to rotate, and the control rod 33 drives the material distribution cylinder 4 to move downward until the lower end of the material distribution cylinder 4 is inside the lower mold 2, at which point the rotation stops. At this time, the control rod 33... The other side of 3 abuts against the second stop rod 35; after the feeding is finished, the second motor 32 drives the threaded rod 31 to rotate in the opposite direction, and the uniform material cylinder 4 plays a limiting role on the control rod 33 in the lower mold 2. The control rod 33 moves up. When the uniform material cylinder 4 is completely moved out of the lower mold 2, it continues to move up a distance due to the limiting effect of the second stop rod 35. When the height of the control rod 33 is higher than the top of the second stop rod 35, the control rod 33 rotates together with the threaded rod 31, thereby driving the uniform material cylinder 4 to move to the outside of the lower mold 2, which facilitates the graphite pressing operation.

[0024] The uniform feeding cylinder 4 is equipped with a grid plate 41, which can block lumps that exceed the specifications. A guide plate 44 is located on one side of the top of the uniform feeding cylinder 4. The guide plate 44 is inclined and located below the outlet of the external conveying mechanism. It is used to receive the mixed graphite powder and guide it into the uniform feeding cylinder 4. After being screened by the grid plate 41, it is fed into the lower mold 2. A stirring shaft 42 is rotatably mounted at the bottom of the grid plate 41, and a stirring rod 43 is mounted on the stirring shaft 42. A drive wheel 52 is rotatably mounted at the bottom of the grid plate 41, coaxially connected to the stirring shaft 42 and located at the top of the stirring shaft 42. Another drive wheel 52 is located on the outside of the uniform feeding cylinder 4, and the two drive wheels 52 are connected by a synchronous belt 53. A first motor 5 is located on the outside of the uniform feeding cylinder 4. 1. The first motor 51 is connected to the transmission wheel 52 on the outside of the uniform material cylinder 4. The bottom of the grid plate 41 is provided with a protective cover 5. The stirring shaft 42 passes through the protective cover 5 and is rotatably connected to the protective cover 5. The side of the uniform material cylinder 4 has an opening. One end of the protective cover 5 passes through the opening on the side of the uniform material cylinder 4 and extends out to the outside. The transmission wheel 52 and the first motor 51 are both located inside the protective cover 5 to prevent graphite powder from entering the uniform material cylinder 4 and damaging the transmission wheel 52 when the material is fed. The first motor 51 drives the transmission wheel 52 to rotate, and through the connection of the synchronous belt 53 and the transmission wheel 52, it drives the stirring shaft 42 to rotate. The stirring rod 43 stirs the graphite powder that has passed through the grid plate 41 and entered the lower mold 2, so that the material is evenly distributed in the lower mold 2, thereby making the mold pressing quality uniform.

[0025] The uniform material cylinder 4 has a mounting frame 6 on one side. The mounting frame 6 is U-shaped and located on the top of the protective cover 5. A rotating shaft 61 is rotatably mounted on the mounting frame 6, and a push rod 62 is mounted on the rotating shaft 61. A spring 63 is mounted on the mounting frame 6, and a push plate 64 is connected to one end of the spring 63. The push plate 64 is L-shaped, and a telescopic rod 66 is located inside the spring 63. The two ends of the telescopic rod 66 are connected to the mounting frame 6 and the push plate 64, respectively. A striking ball 65 is provided on the upper side of the push plate 64, and the striking ball 65 contacts the side of the uniform material cylinder 4. The output end of the first motor 51 is connected to a driving bevel gear 54, which is coaxially arranged with one of the transmission wheels 52. A driven bevel gear 55 is rotatably mounted on the mounting frame 6, and the driving bevel gear 54 and the driven bevel gear 55 are meshed together. The rotating shaft 61 is coaxially connected with the driven bevel gear 55. When the first motor 51 rotates, it drives the driven bevel gear 55 to rotate through the active bevel gear 54, thereby driving the rotating shaft 61 to rotate. When the push rod 62 of the rotating shaft 61 rotates to the side of the push plate 64, it pushes the push plate 64 and the striking ball 65 away from the outside of the uniform material cylinder 4 and squeezes the spring 63. When the push rod 62 disengages from the push plate 64, the elastic force of the spring 63 causes the push plate 64 to drive the striking ball 65 to strike the side of the uniform material cylinder 4, accelerating the feeding of the uniform material cylinder 4.

[0026] The working principle of this utility model is as follows: When it is necessary to feed material into the lower mold 2, the second motor 32 drives the threaded rod 31 to rotate. At this time, the height of the control rod 33 is not blocked by the first stop rod 34 and the second stop rod 35. The control rod 33 drives the uniform cylinder 4 to rotate synchronously with the threaded rod 31. When the uniform cylinder 4 moves above the lower mold 2, one side of the control rod 33 abuts against the first baffle. The threaded rod 31 continues to rotate, and the control rod 33 drives the uniform cylinder 4 to move down until the lower end of the uniform cylinder 4 is inside the lower mold 2. Then, it stops rotating. This is used to receive the mixed graphite powder and introduce it into the uniform cylinder 4. After being screened by the grid plate 41, it is sent into the lower mold 2. The first motor 51 drives the transmission wheel 52 to rotate, and through the connection of the synchronous belt 53 and the transmission wheel 52, it drives the stirring shaft 42 to rotate. The stirring rod 43 stirs the graphite powder that has entered the lower mold 2 after being screened by the grid plate 41, so that the material... The material is evenly distributed in the lower mold 2. When the first motor 51 rotates, it drives the driven bevel gear 55 to rotate through the active bevel gear 54, thereby driving the rotating shaft 61 to rotate. When the push rod 62 of the rotating shaft 61 rotates to the side of the push plate 64, it pushes the push plate 64 and the striking ball 65 away from the outside of the uniform material cylinder 4 and squeezes the spring 63. When the push rod 62 disengages from the push plate 64, the elastic force of the spring 63 causes the push plate 64 to drive the striking ball 65 to strike the side of the uniform material cylinder 4. After the material is fed, the second motor 32 drives the threaded rod 31 to rotate in the opposite direction. It continues to move upward a certain distance due to the limiting effect of the second stop rod 35. When the height of the control rod 33 is higher than the top of the second stop rod 35, the control rod 33 rotates together with the threaded rod 31, thereby driving the uniform material cylinder 4 to move to the outside of the lower mold 2. The cylinder 21 drives the lower mold 2 to move into the upper mold 22, applying pressure to the graphite powder to form it and completing the pressing operation.

[0027] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
