Description

Technical Field

[0001] This invention relates to the technical field of drum grinding, specifically to an online vibratory grinding device for a mixer drum. Background Technology

[0002] The mixer is a crucial piece of equipment in the sintering process, a large piece of equipment that provides uniform sintering raw materials. If the mixer malfunctions and stops, the entire production line will cease operation. The mixer requires high precision in manufacturing and installation. Due to long service life and poor tire lubrication, problems such as horizontal lines and surface pits may appear on the mixer tires and rollers. Continuous deterioration can lead to a mixer runout greater than 10mm, at which point maintenance is necessary.

[0003] According to Chinese Patent Publication No. CN209998671U, a roller ring repair device for a cylindrical mixer includes a support frame, a trunnion, a self-aligning device, a centering device, a transmission device, a roller ring turning device, and a roller ring grinding device. One end of the trunnion is rotatably mounted on the support frame, and the other end of the trunnion is rotatably connected to a cross-shaped bracket, which is fixedly connected to the inside of the cylinder. The self-aligning device is mounted on the trunnion and installed at both ends inside the cylinder. The centering device is installed on the cylinder to determine the center line of the cylinder. The roller ring turning device and the roller ring grinding device are located on one side of the cylinder and are flush with the horizontal center line of the outer roller ring of the cylinder. The transmission device is connected to the cylinder to drive the cylinder to rotate around the support frame, thereby enabling the roller ring turning device and the roller ring grinding device to turn and fine grind the roller ring.

[0004] In the above solution, grinding is used to repair the roller ring of the mixer, which still has the following disadvantages: during the grinding process, the object being ground will bounce and jump due to the contact friction with the grinding blade. When the bounce and jump are resolved, the machine needs to be stopped for maintenance, which takes a long time and reduces production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an online grinding device for a mixer drum vibration to solve the problem that the object being ground will bounce and jump due to contact friction with the grinding blade, and that stopping the machine for maintenance is required to solve the bounce and jump, which takes a long time and reduces production efficiency.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: an online grinding device for a mixer drum vibration, comprising a fixed base, a drum body rotatably disposed above the fixed base, a tire sleeved on the drum body, two support plates fixed on the top surface of the fixed base, a mounting U-shaped plate flipped above the fixed base, a grinding blade slidably disposed inside the mounting U-shaped plate, several springs fixed on the bottom surface of the grinding blade, the other end of the springs fixed to the inner bottom surface of the mounting U-shaped plate, two fixing plates fixed on the bottom surface of the mounting U-shaped plate, a rotating hole opened on one side of the support plate, a rotating hole opened on one side of the fixing plate, a pressing bolt rotatably disposed inside the rotating hole, one end of the pressing bolt passing through the rotating hole and threadedly connected to the rotating hole.

[0007] Preferably, the inner bottom surface of the mounting U-shaped plate is provided with a plurality of socket holes, and the bottom surface of the grinding tool is fixed with a plurality of sliding posts, the sliding posts being slidably inserted into the socket holes, and the spring being arranged around the sliding posts.

[0008] Preferably, two mounting plates are respectively provided on both sides of the tire, a sliding plate is slidably provided on the top surface of the mounting plate, a drag wheel is provided between the tire and the grinding wheel, a drive motor is fixed on the top surface of the sliding plate, a grinding wheel is rotatably provided on one side of the drive motor, a limit hole is opened on one side of the grinding wheel, and a fixing ring is fixed on the surface of the output shaft of the drive motor.

[0009] Preferably, the top surface of the mounting plate has a sliding groove, the bottom surface of the sliding plate has a sliding strip fixed, one side of the sliding strip has a threaded hole, one side of the mounting plate has a positioning hole, a transverse screw is rotatably disposed inside the positioning hole, the transverse screw is threadedly connected to the threaded hole, a slide rail plate is slidably disposed below the mounting plate, two limiting plates are fixed to the bottom surface of the mounting plate, translation grooves are respectively disposed on both sides of the slide rail plate, a connecting strip is fixed to the bottom surface of the mounting plate, a moving groove is disposed on the top surface of the slide rail plate, the surface of the connecting strip is slidably disposed with the interior of the moving groove, fixing holes are respectively disposed on both sides of the interior of the moving groove, a longitudinal screw is rotatably disposed inside the fixing hole, the longitudinal screw is threadedly connected to the connecting strip.

[0010] Preferably, one end of the transverse screw passes through a positioning hole and is fixed with a turntable, and two handles are fixed on one side of the turntable.

[0011] Preferably, a stabilizing groove is provided on one side of the sliding groove, and the stabilizing groove is rotatably connected to the other end of the transverse screw.

[0012] Preferably, a limit strip is fixed to the surface of the output shaft of the drive motor, and a limit groove is formed inside the limit hole, with the limit strip slidably inserted into the limit groove.

[0013] Preferably, one end of the output shaft of the drive motor is provided with a threaded groove, and a fixing bolt is threadedly connected inside the threaded groove.

[0014] Compared with existing technologies, the online grinding device for a mixer drum vibration using the above-mentioned technical solution has the following advantages:

[0015] 1. The drum body rotates under the drive of the mixer, with a rotation speed of 5-6 revolutions per minute. As the drum body drives the belt to rotate synchronously, the surface of the belt contacts and grinds the top surface of the grinding blade during belt rotation. When the belt contacts the top surface of the grinding blade, the belt applies pressure, pressing the grinding blade into the mounting U-shaped plate. As the mounting U-shaped plate moves downwards, it causes the sliding column to slide downwards inside the socket, compressing the spring and fixing the position between the belt and the grinding blade. After this, the compressed spring applies pressure to the grinding blade. By applying an upward force, the interaction and friction between the tire and the grinding blade are increased. Since the U-shaped plate and the support plate are connected by a fixed plate, extrusion bolts, rotating holes and rotating holes, the angle of the grinding blade can be adjusted, allowing the grinding blade to better fit the surface of the tire. This solves the problem of large runout deviation without stopping the machine, eliminating maintenance time. By using online grinding instead of offline turning to deal with the vibration of the roller body, the equipment does not need to be stopped for a long time. This overcomes the bottleneck problem that only stopping the machine and production can solve the vibration of the roller body, and increases production efficiency.

[0016] 2. Based on the measured feed rate, the operator will use the handle and turntable to drive the transverse screw to rotate. The threaded connection between the transverse screw and the threaded hole will push the sliding bar to slide inside the sliding groove, thereby changing the transverse position of the sliding plate. Subsequently, the operator can rotate the longitudinal screw. The rotating longitudinal screw will use the threaded connection with the connecting bar to push the connecting bar to slide inside the moving groove, thereby changing the longitudinal position of the mounting plate, the sliding plate, and the grinding wheel. This ensures that the grinding wheel and the drag wheel are in full contact and grind along the axis from one side to the other until the roughness is within 0.2mm, which facilitates timely adjustment and increases the precision during machining and grinding.

[0017] 3. When the grinding wheel is damaged, the worker will first unscrew the fixing bolts out of the threaded groove. Then, the worker will remove the damaged grinding wheel from the surface of the drive motor output shaft. The worker will then reattach the intact grinding wheel to the drive motor output shaft and insert the limit strip into the limit groove. This will allow the grinding wheel to rotate when the drive motor output shaft rotates, preventing the grinding wheel from slipping during rotation. After the replacement is completed, the fixing bolts will be screwed back into the threaded groove to prevent the grinding wheel from falling out. Attached Figure Description

Detailed Implementation

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-4As shown, an online grinding device for a mixer drum vibration includes a fixed base 1, a drum body 2 rotatably mounted above the fixed base 1, a belt 3 sleeved on the drum body 2, two support plates 4 fixed on the top surface of the fixed base 1, a U-shaped mounting plate 5 flipped above the fixed base 1, a grinding blade 6 slidably mounted inside the U-shaped mounting plate 5, several springs 9 fixed on the bottom surface of the grinding blade 6, the other end of the springs 9 fixed to the inner bottom surface of the U-shaped mounting plate 5, two fixing plates 11 fixed on the bottom surface of the U-shaped mounting plate 5, a rotating hole 10 opened on one side of the support plate 4, a rotating hole 12 opened on one side of the fixing plate 11, a pressing bolt 13 rotatably mounted inside the rotating hole 12, one end of the pressing bolt 13 passing through the rotating hole 12 and threadedly connected to the rotating hole 10, several socket holes 7 opened on the inner bottom surface of the U-shaped mounting plate 5, several sliding columns 8 fixed on the bottom surface of the grinding blade 6, the sliding columns 8 slidably inserted into the socket holes 7, and the springs 9 and sliding columns 8 arranged around each other.

[0028] During use, the drum body 2 rotates under the drive of the mixer, with a rotation speed of 5-6 revolutions per minute. Since the drum body 2 drives the belt 3 to rotate synchronously, during the rotation of the belt 3, the surface of the belt 3 contacts and grinds the top surface of the grinding blade 6. When the belt 3 contacts the top surface of the grinding blade 6, the belt 3 applies pressure to the grinding blade 6, pressing it into the mounting U-shaped plate 5. When the mounting U-shaped plate 5 moves downwards, it drives the sliding column 8 to slide downwards inside the sleeve hole 7, compressing the spring 9 and completing the fixation of the position between the belt 3 and the grinding blade 6. The compressed spring 9 then... The grinding blade 6 applies an upward force, increasing the force and friction between the tire 3 and the grinding blade 6. Since the U-shaped plate 5 and the support plate 4 are rotatably connected by the fixing plate 11, the clamping bolt 13, the rotating hole 10 and the rotating hole 12, the angle of the grinding blade 6 can be adjusted, allowing the grinding blade 6 to better fit the surface of the tire 3. This solves the problem of large runout deviation without stopping the machine, eliminating maintenance time. By using online grinding instead of offline turning to treat the vibration of the roller body 2, the equipment does not need to be stopped for a long time, overcoming the bottleneck problem that only stopping the machine and production can solve the vibration of the roller body 2, and increasing production efficiency.

[0029] like Figure 2 , Figure 5 and Figure 6As shown, two mounting plates 31 are respectively provided on both sides of the belt 3. A sliding plate 14 is slidably provided on the top surface of the mounting plate 31. A drag wheel 18 is provided between the belt 3 and the grinding wheel 17. A drive motor 15 is fixed on the top surface of the sliding plate 14. The grinding wheel 17 is rotatably provided on one side of the drive motor 15. A limit hole 27 is provided on one side of the grinding wheel 17. A retaining ring 16 is fixed on the surface of the output shaft of the drive motor 15. A sliding groove 19 is provided on the top surface of the mounting plate 31. A sliding strip 21 is fixed on the bottom surface of the sliding plate 14. A threaded hole 22 is provided on one side of the sliding strip 21. A positioning hole 20 is provided on one side of the mounting plate 31. A transverse screw 32 is rotatably provided inside the positioning hole 20. The transverse screw 32 is threadedly connected to the threaded hole 22. The lower part of the mounting plate 31... The sliding plate 33 is provided with a sliding rail plate 33. Two limiting plates 34 are fixed on the bottom surface of the mounting plate 31. Translation grooves 35 are respectively opened on both sides of the sliding rail plate 33. A connecting strip 36 is fixed on the bottom surface of the mounting plate 31. A moving groove 37 is opened on the top surface of the sliding rail plate 33. The surface of the connecting strip 36 is slidably arranged with the inside of the moving groove 37. Fixing holes 38 are respectively opened on both sides of the inside of the moving groove 37. A longitudinal screw 39 is rotatably arranged inside the fixing hole 38. The longitudinal screw 39 is threadedly connected to the connecting strip 36. One end of the transverse screw 32 passes through the positioning hole 20 and is fixed with a turntable 23. Two handles 24 are fixed on one side of the turntable 23. A stabilizing groove 25 is opened on one side of the inside of the sliding groove 19. The stabilizing groove 25 is rotatably arranged with the other end of the transverse screw 32.

[0030] During use, based on the measured feed rate, the operator uses the handle 24 and the turntable 23 to drive the transverse screw 32 to rotate. The threaded connection between the transverse screw 32 and the threaded hole 22 allows the sliding bar 21 to slide within the sliding groove 19, thus changing the transverse position of the sliding plate 14. Subsequently, the operator can rotate the longitudinal screw 39. The rotating longitudinal screw 39, through its threaded connection with the connecting bar 36, pushes the connecting bar 36 to slide within the moving groove 37, thereby changing the longitudinal position of the mounting plate 31, the sliding plate 14, and the grinding wheel 17. This ensures that the grinding wheel 17 fully contacts the drag wheel 18 and grinds along the axis from one side to the other until the roughness is within 0.2mm, facilitating timely adjustments and increasing the precision during grinding.

[0031] like Figure 6 and Figure 7 As shown, a limit strip 26 is fixed on the surface of the output shaft of the drive motor 15, and a limit groove 28 is opened inside the limit hole 27. The limit strip 26 and the limit groove 28 are slidably inserted into each other. A threaded groove 29 is opened at one end of the output shaft of the drive motor 15, and a fixing bolt 30 is threadedly connected inside the threaded groove 29.

[0032] When the grinding wheel 17 is damaged during use, the operator will first unscrew the fixing bolt 30 out of the threaded groove 29. Then, the operator will remove the damaged grinding wheel 17 from the surface of the output shaft of the drive motor 15. The operator will then reattach the intact grinding wheel 17 to the output shaft of the drive motor 15 and insert the limiting strip 26 into the limiting groove 28. This will allow the grinding wheel 17 to rotate when the output shaft of the drive motor 15 rotates, preventing the grinding wheel 17 from slipping during rotation. After the replacement is completed, the fixing bolt 30 will be screwed back into the threaded groove 29 to prevent the grinding wheel 17 from falling off.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
