Description

Technical Field

[0001] The utility model relates to the technical field of graphite processing, in particular to a spherical graphite surface processing device. Background Art

[0002] Spherical graphite uses natural flake graphite as raw material and is formed into a graphite product in the shape of an elliptical sphere through a processing device. It has excellent electrical conductivity and chemical stability and is commonly used as the negative electrode material for lithium-ion batteries. When making spherical graphite, the graphite raw material is placed in a mold and pressed into shape. When spherical graphite of different sizes needs to be made, different molds need to be replaced. However, the molds of some existing spherical graphite surface processing devices are fixed by multiple bolts, and the replacement process is complicated, indirectly reducing the production efficiency.

[0003] The utility model disclosed in the utility model patent with the authorization announcement number of CN 214817311 U discloses a spherical graphite surface processing device, including: a frame; a feeding frame arranged inside the right side of the frame; a graphite forming mechanism connected to the middle position inside the frame; a grinding mechanism connected to the left side position inside the frame; a driving shaft connected to the upper end of the frame through a bearing, and both ends of the driving shaft are fixedly connected with turntables, and a first connecting rod and a second connecting rod are connected to the turntables through shafts; a motor arranged at the upper end of the frame, and the motor is connected to the driving shaft through a belt transmission mechanism. This spherical graphite surface processing device can facilitate the removal of burrs on the surface of spherical graphite, effectively improving the production quality of spherical graphite, and can facilitate the automatic pressing and demolding of graphite, thus improving the production efficiency of spherical graphite.

[0004] Although this device can eject and grind spherical graphite, since both the upper mold and the lower mold are fixedly arranged, it is impossible to quickly replace the mold, and the height of the grinding plate is not adjustable. When the spherical graphite is too large or too small, the grinding plate cannot smoothly grind, affecting the smooth progress of the work. Content of the Utility Model

[0005] In view of this, the utility model provides a spherical graphite surface processing device, which can quickly replace and install the mold, the replacement process is simple, the production efficiency is improved, and the grinding height can be adjusted to improve the applicability of the device.

[0006] To solve the above technical problems, the present utility model provides a spherical graphite surface processing device, which includes a workbench, an upper mold, a lower mold and a grinding plate. A conveying mechanism is arranged inside the lower part of the workbench. On one side of the upper surface of the workbench, there is a support frame. On both sides of the upper surface of the support frame, there are hydraulic rods. The output end of the hydraulic rod is provided with a fixing plate. In the center of the fixing plate, there is a fixing frame. Inside the fixing frame, there is a quick replacement mechanism for replacing the upper mold. On the upper surface of the workbench and at a position corresponding directly below the upper mold, there is a placement groove. The lower mold is installed in the placement groove. On both sides of the placement groove, there are sliding grooves. On both sides of the lower mold, there are sliding blocks, and the sliding blocks are slidably arranged in the sliding grooves of the placement groove. On the upper surface of the workbench and at a position corresponding above the conveying mechanism, there is a grinding mechanism for grinding the graphite. The grinding plate is installed in the grinding mechanism. The grinding mechanism includes an adjustment component for adjusting the grinding height and a driving component for driving the grinding plate to perform grinding. When the staff needs to replace the upper mold and the lower mold, the upper mold is replaced and installed through the quick replacement mechanism. Subsequently, the old lower mold is pulled upward from the placement groove on the surface of the workbench, so that the sliding blocks slide upward in the sliding grooves on the inner wall of the placement groove, thereby the old lower mold can be taken out. Then, the new lower mold is installed inside the placement groove, thus facilitating the replacement of the upper mold and the lower mold. When grinding and processing the graphite ball, after the graphite ball is formed in the lower mold and falls on the surface of the conveying mechanism, the grinding height is adjusted through the adjustment component, so that the grinding plate can smoothly grind the graphite ball. Therefore, not only can the mold be quickly replaced and installed, the replacement process is simple, and the production efficiency is improved, but also the grinding height can be adjusted to improve the applicability of the device.

[0007] The quick-changing mechanism includes driving cavities on both sides of the fixed frame, springs are arranged on both sides of the driving cavity, movable plates are arranged at the ends of the springs, a positioning block is arranged at the center of one side of the movable plate, a limiting groove is arranged at the center of the fixed frame, a through hole is arranged on the inner wall of the driving cavity corresponding to the position of the positioning block, and the through hole extends into the limiting groove, a limiting column is arranged at the center of the upper surface of the upper mold, the limiting column is inserted into the limiting groove of the fixed frame, positioning holes are arranged on both sides of the limiting column, the positioning block passes through the through hole of the inner wall of the driving cavity and is inserted into the positioning hole of the limiting column, the lower surface of the positioning block is an inclined surface, notches are arranged on both sides of the outer wall of the fixed frame, handles are arranged on the side wall of the movable plate corresponding to the position of the notch of the fixed frame, the handles are slidingly arranged in the notch of the outer wall of the fixed frame, and when the staff needs to take out the old upper mold, the two handles are pulled to make the handles drive the positioning block to disengage When the upper die is in the positioning hole of the limit column, the positioning block is cancelled and the staff can take out the upper die and make the limit column disengage from the limiting groove of the fixed frame. When a new upper die needs to be installed, the limit column of the new upper die is inserted into the limiting groove of the fixed frame. The upper surface of the limit column contacts the inclined surface of the bottom surface of the positioning block, thereby driving the two positioning blocks to move away from each other and make the positioning block disengage from the limiting groove of the fixed frame. The positioning block drives the movable plate to move synchronously, and the movable plate compresses the spring. When the top surface of the limit column contacts the upper inner wall of the limiting groove, the positioning block corresponds to the positioning hole. The rebound force of the spring pushes the movable plate and the positioning block to move in the direction of the positioning hole, so that the positioning block is inserted into the positioning hole, so that the positioning block limits the limit column and makes the limit column unable to disengage from the limiting groove, thereby completing the installation. The mold can be quickly replaced and the replacement process is simple, which improves production efficiency.

[0008] Through holes are provided on both sides of the movable plate, and guide rods are arranged in the through holes on both sides of the movable plate. The guide rods pass through the center of the spring, and both ends of the guide rods are fixed to the inner wall of the driving cavity. The cross-section of the guide rods is adapted to the cross-section of the through holes of the movable plate, so that the movable plate can slide along the length direction of the guide rods, thereby making the moving process of the movable plate more stable.

[0009] The cross section of the slider is a T-shaped slider, and the slide groove on the inner wall of the placement groove is a T-shaped slide groove. The T-shaped slider can prevent the lower mold position from shifting and improve the stability of the lower mold.

[0010] A handle is provided on the upper surface of the slider. When the staff takes out the lower mold, they can hold the handle to lift the slider and the lower mold upwards, making it more convenient to take out.

[0011] The adjustment component includes drive frames arranged on both sides of the upper surface of the workbench and corresponding above the conveying mechanism. Inside both drive frames, movable blocks are slidably arranged. On the upper surface of the drive frames, motors are provided. The output ends of the motors penetrate the upper walls of the drive frames, and the output ends of the motors are connected with lead screws. Threaded through holes are formed in the centers of the movable blocks, and the lead screws are threadedly connected with the threaded through holes in the centers of the movable blocks. The cross-section of the movable block is square, and the cross-section of the inner wall of the drive frame is adapted to the cross-section of the movable block. A slide rail is arranged on one side of the movable block, and both sides of the grinding plate are slidably arranged in the slide rail. When it is necessary to adjust the distance between the grinding plate and the conveying mechanism, the motor is started. The output end of the motor drives the lead screw to rotate. Since the lead screw is threadedly connected with the threaded through hole in the center of the movable block, and the cross-section of the inner wall of the drive frame is adapted to the cross-section of the movable block, the movable block can move up and down when the lead screw rotates, so that the movable block can drive the slide rail and the grinding plate to move up and down, thereby adjusting the height of the grinding plate and improving the applicability of the device.

[0012] The driving component includes a through groove formed in the upper inner wall of the slide rail. A connecting block is slidably arranged in the through groove. The lower end of the connecting block is fixed on the surface of the grinding plate. A fixing block is arranged at the upper end of the connecting block. On one side of the upper surface of the slide rail, a support plate is arranged. The center of the surface of the support plate is provided with a telescopic push rod. The output end of the telescopic push rod is fixed on the surface of the fixing block. When the staff starts the telescopic push rod, the output end of the telescopic push rod drives the fixing block to move, so that the fixing block drives the connecting block to slide in the through groove, and the connecting block drives the grinding plate to slide back and forth in the slide rail, thereby grinding the graphite balls on the conveying mechanism with the grinding plate.

[0013] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0014] 1. When in use of the present utility model, when the staff needs to replace the upper die and the lower die, the upper die is replaced and installed through the quick replacement mechanism. Subsequently, the old lower die is pulled upward from the placement groove on the surface of the workbench, so that the slider slides upward in the chute on the inner wall of the placement groove, thereby taking out the old lower die. Then, the new lower die is installed inside the placement groove, which is convenient for replacing the upper die and the lower die. When grinding and processing graphite balls, after the graphite balls are formed in the lower die and fall on the surface of the conveying mechanism, the grinding height is adjusted through the adjustment component, so that the grinding plate can smoothly grind the graphite balls. Thus, not only can the die be quickly replaced and installed, the replacement process is simple, and the production efficiency is improved, but also the grinding height can be adjusted to improve the applicability of the device.

[0015] When the tool is in a state of being moved in a new direction, the tool holder can be easily moved by the two handles, and the two handles can be pulled to move the two handles away from each other so that the tool holder can move in a new direction and the tool holder can be easily moved.

[0016] 3.

Detailed implementation manners

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying Figures 1-6 drawings of the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model fall within the scope of protection of the present utility model.

[0026] According to an embodiment of the present utility model, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure: This embodiment provides a spherical graphite surface processing device, including a workbench 100, an upper mold 500, a lower mold 600, and a grinding plate 706. A conveying mechanism 200 is arranged inside the lower part of the workbench 100. On one side of the upper surface of the workbench 100, there is a support frame 300. On both sides of the upper surface of the support frame 300, there are hydraulic rods 301. The output end of the hydraulic rod 301 is provided with a fixing plate 302. At the center of the fixing plate 302, there is a fixing frame 400. Inside the fixing frame 400, there is a quick replacement mechanism for replacing the upper mold 500. On the upper surface of the workbench 100 and at a position corresponding directly below the upper mold 500, there is a placement groove. The lower mold 600 is installed in the placement groove. On both sides of the placement groove, there are sliding grooves. On both sides of the lower mold 600, there are sliders 602. The sliders 602 are slidably arranged in the sliding grooves of the placement groove. On the upper surface of the workbench 100 and at a position corresponding above the conveying mechanism 200, there is a grinding mechanism 700 for grinding graphite. The grinding plate 706 is installed inside the grinding mechanism 700. The grinding mechanism 700 includes an adjustment component for adjusting the grinding height and a driving component for driving the grinding plate 706 to perform grinding. When the staff needs to replace the upper mold 500 and the lower mold 600, the upper mold 500 is replaced and installed through the quick replacement mechanism. Subsequently, the old lower mold 600 is pulled upward from the placement groove on the surface of the workbench 100, so that the sliders 602 slide upward in the sliding grooves on the inner wall of the placement groove, thereby the old lower mold 600 can be taken out. Then, the new lower mold 600 is installed inside the placement groove, thus facilitating the replacement of the upper mold 500 and the lower mold 600. When grinding and processing graphite balls, after the graphite balls are formed in the lower mold 600, they fall onto the surface of the conveying mechanism 200. Subsequently, the grinding height is adjusted through the adjustment component, so that the grinding plate 706 can smoothly grind the graphite balls. Thus, not only can the mold be quickly replaced and installed, the replacement process is simple, and the production efficiency is improved, but also the grinding height can be adjusted to improve the applicability of the device; The cross-section of the slider 602 is a T-shaped slider, and the sliding groove on the inner wall of the placement groove is a T-shaped sliding groove. The T-shaped slider can prevent the lower mold 600 from shifting in position and improve the stability of the lower mold 600; On the upper surface of the slider 602, there is a handle 601. When the staff takes out the lower mold 600, they can hold the handle 601 with their hands to lift the slider 602 and the lower mold 600 upward, making the extraction more convenient;

[0027] Specifically, the quick replacement mechanism includes drive chambers 401 opened on both sides inside the fixed frame 400. Springs 402 are arranged on both sides inside the drive chambers 401. An end of each spring 402 is provided with a movable plate 403. A positioning block 404 is arranged at the center on one side of the movable plate 403. A limiting groove is opened at the center inside the fixed frame 400. Through holes are opened on the inner wall of the drive chamber 401 at positions corresponding to the positioning block 404, and the through holes extend into the limiting groove. A limiting post 501 is arranged at the center on the upper surface of the upper die 500. The limiting post 501 is inserted into the limiting groove of the fixed frame 400. Positioning holes 502 are opened on both sides of the limiting post 501. The positioning block 404 penetrates through the through hole on the inner wall of the drive chamber 401 and is inserted into the positioning hole 502 of the limiting post 501. The lower surface of the positioning block 404 is beveled. Notch openings are opened on both sides of the outer wall of the fixed frame 400. A handle 406 is arranged on the side wall of the movable plate 403 at a position corresponding to the notch opening of the fixed frame 400. The handle 406 is slidably arranged in the notch opening on the outer wall of the fixed frame 400. When a worker needs to take out the old upper die 500, the two handles 406 are pulled to move the handles 406 away from each other, and the handles 406 drive the movable plate 403 to move synchronously. The movable plate 403 compresses the springs 402, and the movable plate 403 drives the positioning block 404 to move synchronously, so that the positioning block 404 disengages from the positioning hole 502 of the limiting post 501, thereby canceling the limitation of the positioning block 404 on the limiting post 501, and then the worker can take out the upper die 500 to make the limiting post 501 disengage from the limiting groove of the fixed frame 400. When a new upper die 500 needs to be installed, the limiting post 501 of the new upper die 500 is inserted into the limiting groove of the fixed frame 400. The upper surface of the limiting post 501 contacts the beveled surface of the bottom surface of the positioning block 404, thereby driving the two positioning blocks 404 to move away from each other, so that the positioning block 404 disengages from the limiting groove of the fixed frame 400. The positioning block 404 drives the movable plate 403 to move synchronously. The movable plate 403 compresses the springs 402. When the top surface of the limiting post 501 contacts the upper inner wall of the limiting groove, the positioning block 404 corresponds to the positioning hole 502. The resilience of the springs 402 pushes the movable plate 403 and the positioning block 404 to move towards the positioning hole 502, so that the positioning block 404 is inserted into the positioning hole 502, thereby limiting the limiting post 501 by the positioning block 404 and making the limiting post 501 unable to disengage from the limiting groove, and then the installation is completed, so that the mold can be quickly replaced and installed, the replacement process is simple, and the production efficiency is improved; Through holes are opened on both sides of the movable plate 403. Guide rods 405 are arranged through the through holes on both sides of the movable plate 403. The guide rods 405 penetrate through the centers of the springs 402, and both ends of the guide rods 405 are fixed on the inner wall of the drive chamber 401. The cross section of the guide rod 405 is adapted to the cross section of the through hole of the movable plate 403, so that the movable plate 403 can slide along the length direction of the guide rod 405, thereby making the movement process of the movable plate 403 more stable;

[0028] According to another embodiment of the present invention, as Figure 5 andFigure 6 As shown in the figure, the adjusting component includes driving frames 701 arranged on both sides of the upper surface of the workbench 100 and corresponding above the conveying mechanism 200. Slide blocks 702 are slidably arranged inside both driving frames 701. A motor 703 is arranged on the upper surface of the driving frame 701. The output end of the motor 703 penetrates the upper wall of the driving frame 701, and a lead screw 704 is connected to the output end of the motor 703. A threaded through hole is formed in the center of the slide block 702, and the lead screw 704 is in threaded connection with the threaded through hole in the center of the slide block 702. The cross-section of the slide block 702 is square, and the cross-section of the inner wall of the driving frame 701 is adapted to the cross-section of the slide block 702. A slide rail 705 is arranged on one side of the slide block 702. Both sides of the grinding plate 706 are slidably arranged in the slide rail 705. When it is necessary to adjust the distance between the grinding plate 706 and the conveying mechanism 200, the motor 703 is started. The output end of the motor 703 drives the lead screw 704 to rotate. Since the lead screw 704 is in threaded connection with the threaded through hole in the center of the slide block 702, and the cross-section of the inner wall of the driving frame 701 is adapted to the cross-section of the slide block 702, the slide block 702 can move up and down when the lead screw 704 rotates, so that the slide block 702 can drive the slide rail 705 and the grinding plate 706 to move up and down, thereby adjusting the height of the grinding plate 706 and improving the applicability of the device. The driving component includes a through groove 707 formed in the upper inner wall of the slide rail 705. A connecting block 708 is slidably arranged in the through groove 707. The lower end of the connecting block 708 is fixed on the surface of the grinding plate 706. A fixing block 709 is arranged at the upper end of the connecting block 708. A support plate 710 is arranged on one side of the upper surface of the slide rail 705. The center of the surface of the support plate 710 is provided with a telescopic push rod 711. The output end of the telescopic push rod 711 is fixed on the surface of the fixing block 709. The staff starts the telescopic push rod 711. The output end of the telescopic push rod 711 drives the fixing block 709 to move, so that the fixing block 709 drives the connecting block 708 to slide in the through groove 707, and the connecting block 708 drives the grinding plate 706 to slide back and forth in the slide rail 705, thereby grinding the graphite balls on the conveying mechanism 200 with the grinding plate 706.

[0029] The using method of the utility model:

[0030] When the staff takes out the lower mold 600, they can hold the handle 601 with their hands and lift the slider 602 and the lower mold 600 upward, so that the slider 602 slides upward in the chute on the inner wall of the placement groove, thereby the old lower mold 600 can be taken out. Then, a new lower mold 600 is installed inside the placement groove. When the staff needs to take out the old upper mold 500, they pull the two handles 406, making the handles 406 move away from each other. And the handles 406 drive the movable plate 403 to move synchronously. The movable plate 403 compresses the spring 402, and the movable plate 403 drives the positioning block 404 to move synchronously, so that the positioning block 404 disengages from the positioning hole 502 of the limit post 501, thereby canceling the limit of the positioning block 404 on the limit post 501. Then the staff can take out the upper mold 500, and the limit post 501 disengages from the limit groove of the fixed frame 400. When a new upper mold 500 needs to be installed, the limit post 501 of the new upper mold 500 is inserted into the limit groove of the fixed frame 400. The upper surface of the limit post 501 contacts the inclined surface of the bottom surface of the positioning block 404, thereby driving the two positioning blocks 404 to move away from each other, making the positioning block 404 disengage from the limit groove of the fixed frame 400. The positioning block 404 drives the movable plate 403 to move synchronously, and the movable plate 403 compresses the spring 402. When the top surface of the limit post 501 contacts the upper inner wall of the limit groove, the positioning block 404 corresponds to the positioning hole 502. The resilience of the spring 402 pushes the movable plate 403 and the positioning block 404 to move towards the positioning hole 502, so that the positioning block 404 is inserted into the positioning hole 502, thereby the positioning block 404 limits the limit post 501, making the limit post 501 unable to disengage from the limit groove, and then the installation is completed. Thus, the mold can be quickly replaced and installed, the replacement process is simple, and the production efficiency is improved. When the distance between the grinding plate 706 and the conveying mechanism 200 needs to be adjusted, the motor 703 is started. The output end of the motor 703 drives the lead screw 704 to rotate. Since the lead screw 704 is in threaded connection with the threaded through hole in the center of the movable block 702, and the cross-section of the inner wall of the driving frame 701 is adapted to the cross-section of the movable block 702, when the lead screw 704 rotates, the movable block 702 can move up and down, so that the movable block 702 can drive the slide rail 705 and the grinding plate 706 to move up and down, thereby the height of the grinding plate 706 can be adjusted, improving the applicability of the device. After the height of the grinding plate 706 is adjusted, the staff starts the telescopic push rod 711. The output end of the telescopic push rod 711 drives the fixed block 709 to move, so that the fixed block 709 drives the connecting block 708 to slide in the through groove 707, and the connecting block 708 drives the grinding plate 706 to slide back and forth in the slide rail 705, thereby the grinding plate 706 grinds the graphite balls on the conveying mechanism 200.

[0031] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle described in the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
