Description

Technical Field

[0001] The present invention belongs to the technical field of sand mills, and specifically relates to a vertical dual-power liftable sand mill. Background Art

[0002] A sand mill is a wet ultrafine grinding device. Initially, natural sand was used as the grinding medium, and now materials such as zirconia beads are mostly used. Its working principle is that the high-speed rotating stirring shaft drives the grinding medium to exert shearing, collision, and friction on the material, thereby achieving the dispersion and refinement of particles.

[0003] In the prior art, for the convenience of maintaining the sand mill, most sand mills adopt a separable setting, that is, the sand grinding tank body can be separated from the stirring mechanism of the sand mill, thus providing sufficient operating space, and then facilitating the user to maintain the sand grinding tank body and the stirring mechanism separately.

[0004] In the prior art vertical sand mills, usually through the cooperation of multiple lifting power sources, the stirring mechanism can be gradually lifted, and then the separation between the stirring mechanism and the tank body can be completed. However, setting multiple lifting power sources requires an additional PLC control circuit for synchronization to control the synchronous movement of each lifting power source to avoid skewing during the lifting of the stirring mechanism, which may cause the stirring mechanism to collide or get stuck. At the same time, although the lifted stirring mechanism obtains sufficient operating space, the sand grinding tank body at its bottom is still restricted by the stirring mechanism at its top, making it impossible for the user to reach into the sand grinding tank to inspect and maintain the inside of the sand grinding tank.

Detailed Embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] Such as Figures 1 to 3As shown, a vertical dual-power liftable sand mill according to an embodiment of the present invention comprises two pairs of support tubes 1; the top surfaces of the two pairs of support tubes 1 are commonly fixedly connected with a top plate 101; the interiors of the support tubes 1 are rotatably connected with threaded rods 2; the surfaces of the threaded rods 2 are threadedly connected with moving tubes 3; the top surfaces of the moving tubes 3 are commonly fixedly connected with a support plate 4; a grinder 5 is installed on the bottom surface of the support plate 4, and the grinder 5 is driven by a servo motor on the top of the support plate 4; a clearance hole 6 is opened on the surface of the top plate 101 at a position corresponding to the grinder 5; the grinder 5 is composed of a grinding rod and a grinding plate; the pairs of support tubes 1 are connected with threaded rods 2; the surfaces of the threaded rods 2 are threadedly connected with moving tubes 3; the top surfaces of the moving tubes 3 are commonly fixedly connected with a support plate 4; a grinder 5 is installed on the bottom surface of the support plate 4, and the grinder 5 is driven by a servo motor on the top of the support plate 4; a clearance hole 6 is opened on the surface of the top plate 101 at a position corresponding to the grinder 5; the grinder 5 is composed of a grinding rod and a grinding plate; The bottom of the support tube 1 is connected to a transmission rod 7 for common rotation; the transmission rod 7 and the threaded rod 2 are driven by a gear set; a gear 18 is provided between the two transmission rods 7; a chain 9 is installed between the gear 18 and the transmission rod 7; the gear 18 is driven by a servo motor; a pair of slide rails 10 are fixed between the support tubes 1 and at the bottom position; the tops of the two slide rails 10 are connected to a support plate 11 for common sliding movement; a sanding tank 12 is installed on the top surface of the support plate 11; during operation, when the embodiment of the present invention is finished grinding and needs to be repaired and maintained, the user needs to first repair the servo motor that provides power to the grinder 5 The motor is powered off, and then the user starts the servo motor at gear 1-8, which drives gear 1-8 to rotate, and the rotating gear 1-8 will synchronously drive the transmission rods 7 on both sides to rotate, and the synchronously rotating transmission rods 7 on both sides drive each threaded rod 2 to rotate synchronously, and finally the synchronously rotating threaded rods 2 will drive the moving tube 3, the support plate 4 and the grinder 5 to rise, so that the grinder 5 passes through the clearance hole 6 on the surface of the top plate 101, and finally the bottom of the grinder is located on the top surface of the top plate 101, at this time, the separation of the grinder 5 and the sanding tank 12 at its bottom is completed, and then the user can maintain and repair the grinder, thereby Through the cooperation of gear 1 8, chain 9, transmission rod 7 and threaded rod 2, the movable tube 3 at each support tube 1 can rise synchronously, which not only saves the use of power source, but also avoids the use of PLC circuit for synchronous control, thereby reducing the manufacturing cost of the embodiment of the present invention. At the same time, when the grinder 5 is fully lifted to the top of the top plate 101, the user can also pull the support plate 11 so that the support plate 11 drives the sanding tank 12 to slide along the slide rail 10, so that the sanding tank 12 is no longer located on the bottom surface of the grinder 5, thereby freeing up enough space for the user, making it convenient for the user to maintain and repair the sanding tank 12.

[0023] like Figures 1 to 4As shown in the figure, a cross bar 13 is fixedly connected to the bottoms of the two pairs of support pipes 1 on both sides; a rotating arm 14 is rotatably connected to the top surface of the cross bar 13; a clamping plate 15 is rotatably connected to one side of the two rotating arms 14 close to each other; the clamping plate 15 is arc-shaped and is adapted to the outer wall of the abrasive grinding tank 12; two pairs of symmetrically arranged limiting plates 16 are fixedly connected to the side of the clamping plate 15 away from the abrasive grinding tank 12; limiting holes 17 are formed on the surfaces of the limiting plates 16; a limiting rod 18 is fixedly connected to the bottom surface of the support plate 4 at a position corresponding to the limiting holes 17, and the limiting rod 18 is slidably connected to the top plate 101; during operation, after the grinder 5 and the tank body are overhauled and maintained, the user needs to push the support plate 11 to move the abrasive grinding tank 12 back to the bottom of the grinder 5, and then the user rotates the rotating arms 14 at the two cross bars 13 and makes the clamping plates 15 at the ends of the rotating arms 14 fit on the surface of the abrasive grinding tank 12. Then the user drives the moving pipe 3 to drive the support plate 4 to descend, so as to insert the grinder 5 into the inside of the abrasive grinding tank 12. During this process, the support plate 4 will also drive the limiting rod 18 to descend, and the limiting rod 18 can be inserted into the limiting holes 17 on the surface of the limiting plate 16, thereby restricting the displacement of the limiting plate 16 in the horizontal direction. Since the limiting plate 16 is fixedly connected to the clamping plate 15, and the clamping plate 15 is rotatably connected to the rotating arm 14, the clamping plate 15 can clamp the abrasive grinding tank 12 from both sides of the abrasive grinding tank 12, thereby preventing the abrasive grinding tank 12 from shaking violently during grinding, which affects the grinding effect of the product.

[0024] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9As shown, the diameter of the limiting rod 18 is smaller than that of the limiting hole 17; the limiting rod 18 is provided with a hollow structure; a pair of pressing plates 19 are slidably connected to the surface of the limiting rod 18 at positions corresponding to the limiting plate 16; the pressing plates 19 are both arc-shaped, and the pressing plates 19 are adapted to the inner wall of the limiting hole 17; the top of the limiting rod 18 is connected to an external hydraulic system for controlling the ejection of the pressing plates 19; the hydraulic system injects hydraulic oil into the inside of the hollow limiting rod 18 to push the pressing plates 19 slidably connected to the limiting rod 18 to move away from the limiting rod 18; during operation, when the limiting rod 18 is inserted into the limiting hole 17, the external hydraulic system will drive the pressing plates 19 on the surface of the limiting rod 18 to move towards the inner wall of the limiting hole 17, and finally the pressing plates 19 will tightly fit on the inner wall of the limiting hole 17, thereby restricting the movement of the limiting plate 16, and further restricting the movement of the clamping plate 15 fixedly connected to the limiting plate 16, thereby improving the clamping effect of the clamping plate 15 on the grinding tank 12. At the same time, when the user needs to withdraw the limiting rod 18 from the limiting hole 17, the external hydraulic system will drive the pressing plates 19 to approach the limiting rod 18, so that the pressing plates 19 no longer press the inner wall of the limiting hole 17, so that when the limiting rod 18 is withdrawn from the limiting hole 17, it will not be worn, thus ensuring both the restriction of the limiting rod 18 on the limiting plate 16 and the fact that the limiting rod 18 will not be affected by the frictional force between it and the inner wall of the limiting hole 17 during movement.

[0025] As Figure 4 shown, a bottom plate 20 is fixedly connected to the bottom surfaces of the two cross bars 13; a second gear 21 is rotatably connected to the bottom surface of the bottom plate 20; both sides of the second gear 21 are meshed with a toothed plate 22; a transmission plate 23 is fixedly connected to each side of the two toothed plates 22 away from each other, and the transmission plate 23 is L-shaped; the top of the transmission plate 23 is meshed with the bottom of the rotating arm 14; during operation, when the user rotates one of the rotating arms 14, since the transmission plate 23 is meshed with the bottom of the rotating arm 14, when the rotating arm 14 rotates, it will also drive the transmission plate 23 at its bottom to slide, and the transmission plate 23 will drive the toothed plate 22 to move, and the moving toothed plate 22 will drive the toothed plate 22 on the other side to move through the second gear 21, and the toothed plate 22 on the other side will drive the transmission plate 23 fixedly connected to it to move, and then the transmission plate 23 on the other side will drive the rotating arm 14 to rotate. Thus, the user only needs to rotate one of the rotating arms 14 to control the synchronous rotation of the rotating arm 14 on the other side, thereby reducing the operation difficulty of the user and improving the usability of the embodiment of the present invention.

[0026] As Figure 2 and Figure 6As shown, a telescopic rod 24 is fixedly connected to the bottom surface of the support plate 4 and close to the side of the gear 8; the top of the telescopic rod 24 is slidably connected to the top plate 101; the bottom surface of the telescopic rod 24 is fixedly connected to a limit block 25; a limit groove 26 is provided on the surface of the support plate 11 at a position corresponding to the limit block 25; the limit groove 26 is adapted to the limit block 25, and the limit groove 26 passes through the support plate 11; during operation, in the process of the support plate 4 driving the grinder 5 to rise, the limit block 25 at the bottom of the telescopic rod 24 will always be located in the limit groove 26 under the action of its own gravity and the friction between it and the limit groove, thereby limiting the support plate 11 , to prevent the grinder 5 from completely leaving the sanding jar 12 and causing the support plate 11 to drive the sanding jar 12 to slide, thereby causing the grinder 5 to collide with the inner wall of the sanding jar 12, thereby causing damage to both. When the bottom of the grinder 5 rises to be flush with the bottom surface of the top plate 101, the telescopic rod 24 reaches its maximum length that can be extended, the support plate 4 continues to drive the grinder 5 to rise, and the telescopic rod 24 will also rise together, thereby causing the bottom of the limit block 25 to completely leave the limit groove 26, thereby completely leaving the grinder 5 from the sanding jar 12, and the user can now push the support plate 11 and the sanding jar 12 normally.

[0027] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, both sides of the sanding jar 12 are fixedly connected with a rotating column 27; the surfaces of the two rotating columns 27 are rotatably connected to the support seat 28; the surface of the support plate 11 is provided with a through groove 29 at the corresponding position of the support seat 28; the support seat 28 is slidably connected in the through groove 29, and the through groove 29 is adapted to the support seat 28; both sides of the support seat 28 are fixedly connected with a baffle 30; during operation, when the user pulls the support plate 11 to move to the side of the slide rail 10 away from the support tube 1, the user can pull the support seat 28 upward, so that the support seat 28 moves upward along the through groove 29 and the baffle 30 is separated from the top surface of the support plate 11, and then the user rotates the sanding jar 12 again, so that the sanding jar 12 deflects 90 degrees. At this time, the pipe mouth of the sanding jar 12 is set horizontally, which is convenient for the user to clean the inside of the sanding jar 12 and allow the cleaned dirt to flow out of the sanding jar 12 more easily, thereby reducing the maintenance difficulty of the user.

[0028] like Figure 2 、 Figure 5 and Figure 6As shown, the support base 28 extends to the bottom of the pallet 11; on one side of the two slide rails 10 away from the support tube 1, a pair of hydraulic cylinders 31 are fixedly connected, and the two hydraulic cylinders 31 respectively correspond to the positions of the two support bases 28; on one side of the bottom of the support base 28 close to the hydraulic cylinder 31, a relief groove 32 is opened; during operation, when the user needs to lift the support base 28, the user pulls the pallet 11 towards the hydraulic cylinder 31. At this time, the telescopic end at the top of the hydraulic cylinder 31 will pass through the relief groove 32 at the bottom of the support base 28, and the hydraulic cylinder 31 will be just located at the bottom of the support base 28. Then, the telescopic end of the hydraulic cylinder 31 rises, thereby driving the support base 28 to rise. Then, the user can normally rotate the grinding tank 12. By using the hydraulic cylinder 31 to assist the user in lifting the support base 28, the deflection of the grinding tank 12 can be achieved, and only one person is required to complete it, thereby reducing the operation difficulty and improving the usability.

[0029] As Figure 5 and Figure 7 As shown, an installation groove 33 is opened at the top of the support base 28; a turntable 34 is fixedly connected to the surface of the rotating column 27 at the installation groove 33; the turntable 34 is made of aluminum; both inner walls on both sides of the installation groove 33 are inlaid with rubidium magnets 35; during operation, when the user rotates the grinding tank 12, the grinding tank 12 will also drive the turntable 34 on its surface to rotate together. Since the turntable 34 is made of aluminum, when it rotates in the installation groove 33, the turntable 34 will cut the magnetic induction lines between the two rubidium magnets 35, thereby generating eddy currents, and the eddy currents will be subjected to the Lorentz force in the magnetic field, and then a braking torque opposite to the rotation direction of the turntable 34 will be generated. Then, a damping effect will be generated during the rotation of the grinding tank 12, avoiding the grinding tank 12 from rotating too fast and directly hitting the surface of the pallet 11, thereby causing damage to the grinding tank 12. The expression of the Lorentz force is F = qvBsinθ. In this formula, F is the Lorentz force, q is the electric charge, v is the linear velocity of the turntable 34, and B is the magnetic field strength. That is, the faster the grinding tank 12 drives the turntable 34 to rotate, the greater the Lorentz force generated, and the stronger the damping effect generated.

[0030] As Figure 2 and Figure 8As shown, the top surface of the top plate 101 is slidably connected to a pair of symmetrically arranged movable plates 36; the two movable plates 36 are fixed by bolts; a half-cylinder 37 is installed in the middle of the two movable plates 36; the two half-cylinders 37 can be spliced into a complete cylindrical structure, and the cylindrical structure is adapted to the grinding rod in the grinder 5; during operation, when the user needs to replace the grinder 5, the user needs to control the bottom of the grinder 5 to fully rise to the top surface of the top plate 101, and then the user can slide the two movable plates 36 to move the two movable plates 36 toward each other, and finally make the two half-cylinders 37 buckle together, and make the bottom of the grinding rod in the grinder 5 just located between the two half-cylinders 37, and then the user fixes the movable plates 36 together by bolts, and then the user starts to disassemble the grinder 5. When the grinder 5 is separated from the support plate 4, since the bottom is restricted by the two half-cylinders 37, the grinding will not fall over or fall directly from the makeshift hole 6, thereby facilitating the user to disassemble the grinder 5.

[0031] like Figure 8 As shown, the half cylinder 37 is slidably connected to the movable plate 36; the two half cylinders 37 are rotatably connected to a pair of rotating plates 38 on the side away from each other; the surface of the top plate 101 is provided with a sliding groove 39 at the corresponding position of the rotating plate 38; the sliding groove 39 is adapted to the rotating plate 38, and the sliding groove 39 passes through the movable plate 36; during operation, in order to facilitate the user to remove the disassembled grinder 5, the user can rotate the rotating plate 38 at one side of the half cylinder 37 to align it with the sliding groove 39, at this time the half cylinder 37 on this side can slide downward, thereby allowing the grinding rod in the grinder 5 to be moved out of the half cylinder 37 on this side, and finally can be removed from the top plate 10 by the user. 1 and the support plate 4, and then the user puts the new grinder 5 to be replaced between the top plate 101 and the support plate 4, and moves the grinding rod in the grinder 5 between the two half-cylinders 37. Then the user pulls up the half-cylinder 37 at the bottom. When the bottom of the rotating plate 38 moves to the top surface of the movable plate 36, the rotating plate 38 is rotated so that the rotating plate 38 is no longer aligned with the slide groove 39. At this time, the two half-cylinders 37 are reassembled into a complete cylindrical structure and restrict the grinding rod in the grinder 5. As a result, the user can free both hands to connect the grinder 5 to the servo motor at the support plate 4, thereby facilitating the replacement of the grinder 5 by the user.

[0032] During operation, when the embodiment of the present invention finishes grinding and needs to be repaired and maintained, the user needs to first cut off the power to the servo motor that provides power to the grinder 5, and then start the servo motor at gear 1-8, which drives gear 1-8 to rotate, and the rotating gear 1-8 will synchronously drive the transmission rods 7 on both sides to rotate, and the synchronously rotating transmission rods 7 on both sides will drive each threaded rod 2 to rotate synchronously, and finally the synchronously rotating threaded rods 2 will drive the moving tube 3, the support plate 4 and the grinder 5 to rise, so that the grinder 5 passes through the clearance hole 6 on the surface of the top plate 101, and finally the bottom of the grinder is located on the top surface of the top plate 101, and the grinding of the grinder 5 and the sanding tank 12 at its bottom is completed. Separate, and then the user can maintain and repair the grinding, thereby through the cooperation of gear 18, chain 9, transmission rod 7 and threaded rod 2, the moving tube 3 at each support tube 1 can rise synchronously, which saves the use of power source and avoids the use of PLC circuit for synchronous control, thereby reducing the manufacturing cost of the embodiment of the present invention. At the same time, when the grinder 5 is fully lifted to the top of the top plate 101, the user can also pull the support plate 11, so that the support plate 11 drives the sanding tank 12 to slide along the slide rail 10, so that the sanding tank 12 is no longer located on the bottom surface of the grinder 5, thereby freeing up enough space for the user, thereby facilitating the user to maintain and repair the sanding tank 12.

[0033] After the maintenance of the grinder 5 and the tank body is completed, the user needs to push the support plate 11 to move the sanding jar 12 back to the bottom of the grinder 5, and then the user rotates the rotating arms 14 at the two side cross bars 13 to make the clamping plates 15 at the ends of the rotating arms 14 fit the surface of the sanding jar 12, and then the user drives the moving tube 3 to drive the support plate 4 to descend, thereby extending the grinder 5 into the interior of the sanding jar 12. In this process, the support plate 4 will also drive the limit rod 18 to descend, and the limit rod 18 can be inserted into the limit hole 17 on the surface of the limit plate 16, thereby limiting the horizontal displacement of the limit plate 16. Because the limit plate 16 is fixedly connected to the clamping plate 15, and the clamping plate 15 is rotatably connected to the rotating arm 14, the clamping plate 15 can clamp the sanding jar 12 from both sides of the sanding jar 12, thereby preventing the sanding jar 12 from shaking violently during the grinding process, which affects the product grinding effect.

[0034] After the limit rod 18 is inserted into the limit hole 17, the external hydraulic system will drive the pressing plate 19 on the surface of the limit rod 18 to move towards the inner wall of the limit hole 17, and finally make the pressing plate 19 closely fit against the inner wall of the limit hole 17. Thus, the movement of the limit plate 16 can be restricted, and further the movement of the clamping plate 15 fixedly connected to the limit plate 16 can be restricted, thereby improving the clamping effect of the clamping plate 15 on the grinding tank 12. At the same time, when the user needs to withdraw the limit rod 18 from the limit hole 17, the external hydraulic system will drive the pressing plate 19 to approach the limit rod 18, so that the pressing plate 19 no longer presses against the inner wall of the limit hole 17. As a result, during the process of withdrawing the limit rod 18 from the limit hole 17, the limit rod 18 will not be worn, thus ensuring both the restriction of the limit rod 18 on the limit plate 16 and that the limit rod 18 will not be affected by the frictional force between it and the inner wall of the limit hole 17 when moving.

[0035] When the user rotates the rotating arm 14 on one side, since the transmission plate 23 is meshed and connected to the bottom of the rotating arm 14, when the rotating arm 14 rotates, it will also drive the transmission plate 23 at its bottom to slide. And the transmission plate 23 will drive the toothed plate 22 to move. The moving toothed plate 22 will drive the toothed plate 22 on the other side through the second gear 21. The toothed plate 22 on the other side will drive the transmission plate 23 fixedly connected to it to move, and then the transmission plate 23 on the other side will drive the rotating arm 14 to rotate. Thus, the user only needs to rotate the rotating arm 14 on one side to control the synchronous rotation of the rotating arm 14 on the other side, thereby reducing the operation difficulty of the user and improving the usability of the embodiment of the present invention.

[0036] During the process of the support plate 4 driving the grinder 5 to rise, the limit block 25 at the bottom of the telescopic rod 24 will always be located within the limit groove 26 under the action of its own gravity and the frictional force between it and the limit groove. Thus, the support plate 11 can be restricted to prevent the support plate 11 from driving the grinding tank 12 to slide when the grinder 5 has not completely separated from the grinding tank 12, which may lead to a collision between the grinder 5 and the inner wall of the grinding tank 12, resulting in damage to both. When the bottom of the grinder 5 rises to be flush with the bottom surface of the top plate 101, after the telescopic rod 24 reaches the maximum length it can extend, the support plate 4 continues to drive the grinder 5 to rise, and the telescopic rod 24 will also rise along with it, so that the bottom of the limit block 25 completely separates from the limit groove 26. At this time, the grinder 5 has completely separated from the grinding tank 12, and the user can then normally push the support plate 11 and the grinding tank 12.

[0037] When the user pulls the pallet 11 and moves it to the side of the slide rail 10 away from the support tube 1, the user can pull up the support seat 28 upward, so that the support seat 28 moves upward along the through groove 29, and the baffle 30 is separated from the top surface of the pallet 11. Then the user rotates the abrasive grinding tank 12, so that the abrasive grinding tank 12 deflects by 90 degrees. At this time, the nozzle of the abrasive grinding tank 12 is horizontally arranged, which is convenient for the user to clean the inside of the abrasive grinding tank 12, so that the dirt cleaned out can flow out of the abrasive grinding tank 12 more easily, thereby reducing the maintenance difficulty of the user.

[0038] When the user needs to lift the support seat 28, the user pulls the pallet 11 towards the hydraulic cylinder 31. At this time, the telescopic end at the top of the hydraulic cylinder 31 will pass through the relief groove 32 at the bottom of the support seat 28, and the hydraulic cylinder 31 is just located at the bottom of the support seat 28. Then the telescopic end of the hydraulic cylinder 31 rises, thereby driving the support seat 28 to rise. Then the user can normally rotate the abrasive grinding tank 12. By using the hydraulic cylinder 31 to assist the user in lifting the support seat 28, the deflection of the abrasive grinding tank 12 can be achieved with only one person, thereby reducing the operation difficulty and improving the usability.

[0039] When the user rotates the abrasive grinding tank 12, the abrasive grinding tank 12 will also drive the turntable 34 on its surface to rotate together. Since the turntable 34 is made of aluminum, when it rotates in the installation groove 33, the turntable 34 will cut the magnetic induction lines between the two rubidium magnets 35, thereby generating eddy currents. And the eddy currents will be subjected to the Lorentz force in the magnetic field, and then a braking torque opposite to the rotation direction of the turntable 34 will be generated. Then a damping effect will be generated during the rotation of the abrasive grinding tank 12, avoiding the abrasive grinding tank 12 rotating too fast and directly hitting the surface of the pallet 11, thereby causing damage to the abrasive grinding tank 12. The expression of the Lorentz force is F = qvBsinθ. In this formula, F is the Lorentz force, q is the electric charge, v is the linear velocity of the turntable 34, and B is the magnetic field strength. That is, the faster the abrasive grinding tank 12 drives the turntable 34 to rotate, the greater the Lorentz force generated, and the stronger the damping effect generated.

[0040] When the user needs to replace the grinder 5, the user needs to control the bottom of the grinder 5 to rise completely to the top surface of the top plate 101. Then the user can slide the two moving plates 36, so that the two moving plates 36 move towards each other, and finally the two half cylinders 37 are buckled together, and the bottom of the grinding rod in the grinder 5 is just located between the two half cylinders 37. Then the user fixes the moving plates 36 together with bolts. At this time, the user starts to disassemble the grinder 5. When the grinder 5 is separated from the support plate 4, since the bottom is restricted by the two half cylinders 37, the grinder will not fall over and will not directly fall through the relief hole 6, thus facilitating the user to disassemble the grinder 5.

[0041] To facilitate the user in removing the disassembled grinder 5, the user can rotate the rotating plate 38 at one side of the half cylinder 37 to align it with the sliding groove 39. At this time, the half cylinder 37 on this side can slide downward, so that the grinding rod in the grinder 5 can be removed from this side of the half cylinder 37, and finally can be pulled out by the user from between the top plate 101 and the support plate 4. Then the user puts the new grinder 5 to be replaced between the top plate 101 and the support plate 4, and moves the grinding rod in the grinder 5 between the two half cylinders 37. Then the user pulls up the half cylinder 37 at the bottom. When the bottom of the rotating plate 38 moves to the top surface of the moving plate 36, rotate the rotating plate 38 so that the rotating plate 38 is no longer aligned with the sliding groove 39. At this time, the two half cylinders 37 are reassembled into a complete cylindrical structure and restrict the grinding rod in the grinder 5. Thus, the user can free both hands to connect the grinder 5 to the servo motor at the support plate 4, which facilitates the replacement of the grinder 5 by the user.
