Description

An energy-saving conical mill Technical Field

[0001] This utility model relates to the technical field of conical mill structures, specifically an energy-saving conical mill. Background Technology

[0002] Conical mills are suitable for grinding ultrafine particles of various paints and coatings, as well as wet ultrafine particles of water-soluble and oil-based materials. They are ideal equipment for grinding these materials.

[0003] An existing energy-saving conical mill, such as the one with patent publication number CN202113902U, can adjust the distance between the conical grinding roller and the grinding disc by setting an adjustable structure consisting of adjusting bolts and adjusting springs between the lower and middle housings containing the grinding disc. This not only reduces equipment wear, vibration and noise during use, but also allows for adjustment of the grinding particle size as needed.

[0004] However, due to the change in position of the conical mill structure, the device may become mismatched with the milling disc in the housing, resulting in poor reliability. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an energy-saving conical mill with a conical grinding roller structure that can be hinged according to lifting and lowering, which can be adjusted to adapt to the grinding disc of the housing, thereby improving its practicality.

The outer ends of the telescopic rod and the hydraulic cylinder are respectively connected to the inner side of a set of hinge blocks.

[0009] Preferably, the lifting mechanism includes a lifting reciprocating motor, a threaded rod, a lifting solenoid, a connecting frame, a slider, and a guide rail. The top center of the outer frame is connected to the bottom end of the lifting reciprocating motor. The output end of the lifting reciprocating motor is connected to the top of the threaded rod.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides an energy-saving conical mill with the following advantages:

[0016] When the inner frame moves up and down, the telescopic rod can extend and retract according to the actual needs of the shell and grinding disc.

The bottom end of the inner frame 2 is connected to the bottom end of the rotary drive motor 3. The output end of the rotary drive motor 3 is connected to the middle of the top of the crossbeam 4. The two sides of the crossbeam 4 are respectively connected to the middle of the inner side of a set of hinge frames 5. The inner side of the hinge frame 5 is movably connected to the middle of the outer side of the hinge block 7 via the hinge shaft 6. The bottom end of each set of hinge blocks 7 is respectively connected to the top of a set of conical grinding roller shafts 8. The lower outer walls of the two sets of conical grinding roller shafts 8 are rotatably connected to the inner walls of a set of conical grinding rollers 9. The upper inner sides of the two sets of conical grinding roller shafts 8 are... A set of hinged frames 10 are connected to each other. The inner side of the hinged frame 10 is movably connected to the middle of the outer side of the hinge block 12 via the hinge shaft 11. The output end of the telescopic rod 13 is slidably connected to the hydraulic cylinder 14. The outer ends of the telescopic rod 13 and the hydraulic cylinder 14 are respectively connected to the inner side of a set of hinge blocks 12. When the inner frame 2 moves up and down, the hydraulic cylinder 14 can extend and retract the telescopic rod 13 according to the actual needs of the shell and the grinding disc. The two hinge blocks 12 are constrained by the hinge shaft 11 and move within the hinged frame 10. The two hinged frames 5 are constrained by the hinge shaft 6 and the hinge block 7 moves. The conical grinding roller shaft 8 and the conical grinding roller 9 are offset accordingly. After adjustment, they can still be stably fitted on the inner wall of the grinding disc. During operation, the kinetic energy provided by the rotary drive motor 3 makes the cross frame 4 rotate. The two sets of conical grinding rollers 9 are constrained by the conical grinding roller shaft 8 and rotate, acting on the inner wall of the grinding disc for grinding.

[0025] The lifting mechanism includes a lifting reciprocating motor 15, a threaded rod 16, a lifting solenoid 17, a connecting frame 18, a slider 19, and a guide rail 20. The top center of the outer frame 1 is connected to the bottom end of the lifting reciprocating motor 15. The output end of the lifting reciprocating motor 15 is connected to the top end of the threaded rod 16. The outer wall of the threaded rod 16 is screwed to the inner wall of the lifting solenoid 17. The bottom end of the lifting solenoid 17 is connected to the top center of the inner frame 2. The middle of the left and right sides of the inner frame 2 is connected to the middle of the outer side of a set of sliders 19 via a set of connecting frames 18. The upper left and right sides of the inner frame 1 are respectively connected to the outer side of a set of guide rails 20, and the two sets of sliders 19 are respectively slidably set inside the corresponding guide rails 20. When the lifting reciprocating motor 15 runs, the threaded rod 16 can rotate. The threaded rod 16 is screwed into the lifting screw tube 17 and is slidably constrained inside the guide rails 20 by the sliders 19 on both sides. It is then connected to the inner frame 2 and fixed circumferentially by the connecting frame 18, thereby making the inner frame 2 connected to the body lift and lower, and fixed at any height within the range by the threaded rod 16 and the lifting screw tube 17 threaded self-locking.

[0026] It also includes limiting plates 21. The upper and lower sides of each set of guide rails 20 on the inner side of the outer frame 1 are respectively connected to the outer side of a set of limiting plates 21.

[0029] It also includes an oil filling cap 24, and the outer side of each set of oil filling nozzles 23 is detachably installed to the inner side of a set of oil filling caps 24; after the oil filling caps 24 are installed on the outer side of the oil filling nozzles 23, the limiting plate 21 can be externally sealed and protected, improving reliability.

[0030] In summary, when an energy-saving conical mill is in use, the lifting reciprocating motor 15 operates, causing the threaded rod 16 to rotate. The threaded rod 16 is screwed into the lifting screw tube 17 and is slidably constrained on the inner side of the guide rail 20 by the sliders 19 on both sides. It is then connected to the inner frame 2 and circumferentially fixed via the connecting frame 18, thereby causing the inner frame 2 to be connected to the main body to rise and fall. It is fixed at any height within the range by the threaded rod 16 and the lifting screw tube 17. According to the actual needs of the housing and grinding disc, the hydraulic cylinder 14 acts on the telescopic rod 13 to extend and retract. Under the hinge constraint of the hinge blocks 12 on both sides and the hinge shaft 11, the hinge frame 5 on both sides is constrained by the hinge shaft 6, causing the hinge block 7 to move and connect the conical mill. The roller shaft 8 and the conical grinding roller 9 are offset accordingly, and after adjustment, they can still be stably fitted on the inner wall of the grinding disc. During operation, the drive motor 3 provides kinetic energy to rotate the crossbeam 4, and the two sets of conical grinding rollers 9 are constrained by the conical grinding roller shaft 8 to rotate, acting on the inner wall of the grinding disc for grinding. In addition, the two sets of limiting plates 21 can limit the upper and lower sides of the guide rail 20 to prevent the slider 19 from sliding outward. The brush 22 can wipe away dust and impurities on the outside of the guide rail 20 when the slider 19 moves, which is convenient for cleaning and keeps the sliding smooth. The oil injection nozzle 23 can inject oil into the outer wall of the conical grinding roller shaft 8 to facilitate its movement and lubrication with the inner wall of the conical grinding roller 9. After installing the oil injection cap 24 on the outside of the oil injection nozzle 23, the limiting plate 21 can be externally sealed and protected to improve reliability.
