Description

Technical Field

[0001] This invention relates to the field of crucible production equipment technology, and in particular to an automated crucible production line. Background Technology

[0002] A crucible is a container used to melt metals or other substances. It is usually made of materials such as ceramics, iron, and copper. It can withstand high temperatures and maintain a stable state without deformation or cracking during heating. In addition, crucibles can also be used to store liquid metals and other substances, such as lead and tin. In the production process of crucibles, the raw materials must first be selected, and then the forming process is carried out. This can be done by pressing, injection molding, and mold making. After that, sintering is carried out, and then some follow-up processing is required, such as drilling, milling, and grinding and polishing. Nowadays, most of the grinding and polishing of crucibles is done in a semi-manual way. This method is inefficient and the grinding quality is low.

[0003] In the prior art, there is a polishing and grinding assembly for processing stainless steel crucibles (publication number: CN220498686U). The device includes a processing table and a crucible body placed on the processing table, and a grinding roller is provided on the processing table for polishing and grinding the outer surface of the crucible body. This polishing and grinding assembly for processing stainless steel crucibles features a turntable on a processing table. A grinding cylinder for grinding the inner wall of the crucible body is mounted on the turntable. The existing grinding rollers on the processing table are installed on the turntable. This allows the grinding cylinder and grinding rollers to be driven simultaneously during turntable rotation, thus simultaneously grinding the inner and outer walls of the crucible body and improving the overall polishing efficiency.

[0004] However, in actual use, the grinding rollers will wear down during use, and the positions of the two grinding rollers are fixed. This results in poor grinding accuracy of the crucible during the grinding process, and the grinding depth cannot be adjusted according to the grinding requirements of the crucible, which reduces the practicality of the grinding component. Summary of the Invention

The whole process is automated, which can improve the efficiency of crucible grinding and polishing. By adjusting the settings of the motor, threaded rod, and synchronous belt mechanism, the distance between the two grinding rollers can be adjusted, thereby ensuring accurate control of the crucible wall thickness during the grinding process and improving the quality of crucible grinding and polishing. The sprocket assembly causes the grinding roller to move up and down as it rotates. Then, under the action of blower tubes one and two, the airflow is forced onto the crucible wall. The airflow reduces the amount of dust adhering to the crucible wall, thereby reducing the burden on the grinding roller and ensuring its service life. Attached Figure Description

[0019] Example 1, as Figures 1-8 As shown, the present invention proposes an automated crucible production line, comprising: a material conveying mechanism mounted on a fixed frame 1 and driven by a rotating motor 3 for loading and unloading materials; a rotating assembly mounted on the fixed frame 1 and driven by a rotating motor 10 for mounting and rotating the crucible; a rotating assembly mounted on the rotating assembly and driven by a rotating motor 18 for driving a grinding roller 26 to rotate around the crucible; an adjusting mechanism mounted on the rotating assembly and driven by an adjusting motor 21 for adjusting the distance between two grinding rollers 26 via a threaded rod 22; and a blower mechanism mounted on the rotating assembly for blowing air by moving a piston 34 up and down, wherein the blower mechanism is connected to one of the grinding rollers 26 via a sprocket assembly.

[0020] like Figure 1 and Figure 2 As shown, the feeding mechanism includes a rotating column 4 rotatably mounted on a fixed frame 1. A rotating motor 3 is mounted on the fixed frame 1, and the output shaft of the rotating motor 3 is connected to the bottom end of the rotating column 4. Two electric push rods 5 are mounted on the rotating column 4, and the two electric push rods 5 are symmetrically arranged on the rotating column 4.

The bidirectional screw moving assembly consists of a bidirectional screw 7, a clamping motor 8, and two moving blocks. The bidirectional screw 7 is rotatably mounted on the fixed frame 6, and the clamping motor 8 is fixedly mounted on the fixed frame 6. The output shaft of the clamping motor 8 is fixedly connected to one end of the bidirectional screw 7. The two moving blocks are slidably mounted in the fixed frame 6 and are threadedly connected to the bidirectional screw 7. Two clamping plates 9 are provided on one side of the fixed frame 6. The two clamping plates 9 are fixedly connected to the outer wall of one side of the two moving blocks, respectively. The sides of the two clamping plates 9 that are close to each other are both arc surfaces, and the arc surfaces are adapted to the outer wall of the crucible.

[0021] like Figure 1 and Figure 5 As shown, the rotating assembly includes a support frame 11 rotatably mounted on a fixed frame 1. A second rotating motor 10 is mounted on the fixed frame 1. The output shaft of the second rotating motor 10 is connected to the bottom end of the support frame 11. Multiple placement trays 12 and multiple suspension frames 15 are mounted on the support frame 11. The suspension frames 15 are positioned above the placement trays 12. The multiple placement trays 12 and multiple suspension frames 15 are arranged in a ring. Two electric push rods 13 are mounted on the placement trays 12. Arc-shaped clamping plates 14 are mounted on the telescopic shafts of the two electric push rods 13. The bottom of the crucible can be clamped by the arc-shaped clamping plates 14 to ensure the stability of the crucible during the grinding process.

[0022] like Figure 3 and Figure 6As shown, the rotating assembly includes an electric push rod 16 mounted on the suspension bracket 15. A suction disc 17 is mounted on the telescopic shaft of the electric push rod 16. A rotating motor 18 is mounted on the suction disc 17. A rotating rod 19 is rotatably mounted on the suction disc 17. The bottom end of the rotating rod 19 passes through the suction disc 17, and the top end of the rotating rod 19 is connected to the output shaft of the rotating motor 18. An adjusting frame 20 is mounted on the bottom end of the rotating rod 19. The adjusting mechanism includes two threaded rods 22 rotatably mounted on the adjusting frame 20.

The stepper belt assembly 23 consists of three synchronous pulleys and a synchronous belt. The three synchronous pulleys are respectively mounted on one end of the two threaded rods 22 and the output shaft of the adjusting motor 21. The synchronous belt is sleeved on the three synchronous pulleys, so that the two threaded rods 22 can be synchronously driven to rotate by the adjusting motor 21. The threaded rods 22 are symmetrically provided with two opposing external threads. The adjusting frame 20 is provided with two moving seats 24. The two moving seats 24 are threadedly connected to the two threaded rods 22 respectively. A grinding motor 25 is mounted on each of the two moving seats 24. A grinding roller 26 is rotatably mounted on each of the two moving seats 24. The top ends of the two grinding rollers 26 are respectively connected to the output shafts of the two grinding motors 25.

[0023] like Figures 6-8As shown, the blower mechanism includes two connecting plates 27 installed at the bottom of the dust collection disc 17. Blower cylinder 1 28 and blower cylinder 29 are respectively installed at the bottom of the two connecting plates 27. Blower cylinder 1 28 and blower cylinder 29 are respectively located on the inner and outer sides of the crucible. Multiple air holes 30 are opened on both blower cylinder 1 28 and blower cylinder 29. A piston 34 is installed inside both blower cylinder 1 28 and blower cylinder 29. A horizontal partition 31 and a vertical partition 32 are installed inside blower cylinder 1 28, dividing it into three spaces. The piston 34 is located in the uppermost space. Two air guide pipes 33 are installed on the horizontal partition 31, and both air guide pipes 33 communicate with the space where the piston 34 is located. The two air guide pipes 33 are symmetrically arranged on the two sides of the vertical partition 32. On both sides, one-way valves are installed on the two air guide pipes 33. The one-way valves reduce the chance of dust being blown back onto the crucible wall during the dust agitation process. The second blower 29 adopts the same structure as the first blower 28. A pusher frame 35 is installed on the top of the first blower 28. One side of the pusher frame 35 extends into the first blower 28 and the second blower 29 and is connected to the two pistons 34. The pusher frame 35 is slidably connected to the first blower 28 and the second blower 29. A limit rod 36 is fixedly installed on the top of the first blower 28. The limit rod 36 passes through the pusher frame 35 and is slidably connected to the pusher frame 35. A limit block is installed on the top of the limit rod 36. A return spring 37 is sleeved on the limit rod 36. The top of the return spring 37 is connected to the pusher frame 34. 5. The bottom end of the return spring 37 is connected to the top of the blower duct 28. A gear 38 is rotatably mounted on the connecting plate 27 on the blower duct 28. One side of the gear 38 is conical, and the other side is circular. A half gear is set on the circular side of the gear 38. A rotating rod 2 is rotatably mounted on the adjusting frame 20. A sprocket 39 is sleeved on the rotating rod 2. A conical gear 40 is sleeved on the rotating rod 2. The conical gear 40 meshes with the conical side of the gear 38. A rack is set on one side of the push frame 35. The rack meshes with the circular side of the gear 38. Through the half gear on the circular side of the gear 38, after contacting the rack, the push frame 35 is driven to descend. After rotating to a certain position, the gear 38 disengages from the push frame 35. Therefore, the pusher frame 35 can be pushed back to its initial position by the reset spring 37, which can drive the pusher frame 35 to move up and down. The inner grinding roller 26 is equipped with a second sprocket 41. The first sprocket 39 and the second sprocket 41 are connected by a chain 43. The adjusting frame 20 is equipped with a sliding plate 44. A sliding block is slidably installed on the sliding plate 44. The bottom of the sliding block is rotatably equipped with a third sprocket 42. The third sprocket 42 is connected to the chain 43. A fixing ring is installed on the sliding plate 44. A pressure spring 45 is sleeved on the sliding plate 44. The pressure spring 45 is installed between the fixing ring and the sliding block. Through the setting of the third sprocket 42 and the pressure spring 45, the tension of the chain 43 can be ensured when the grinding roller 26 moves, ensuring the normal use of the chain 43.

[0024] In this embodiment, the crucible is transported by a belt conveyor 2. After reaching a suitable location, the crucible is clamped by two clamping plates 9. Then, the first rotating motor 3 is started to move the clamped crucible and place it on the placement tray 12. Subsequently, the second electric push rod 13 is started to push the arc-shaped clamping plate 14 to clamp the bottom of the crucible. Then, the second rotating motor 10 is started to drive the support frame 11 to rotate, which in turn drives the placement tray 12 to rotate, and then drives the crucible to rotate. During the rotation, the corresponding third electric push rod 16 is started to drive the two grinding rollers 26 to descend and enter the inner and outer sides of the crucible. Then, the grinding motor 25 is started to drive the grinding rollers 26 to rotate. The third rotating motor 18 is started to drive the two grinding rollers 26 to rotate around the crucible wall. Then, the adjusting motor 21 is started to drive the two threaded rods 22 to rotate, adjusting the position between the two grinding rollers 26. The grinding rollers 26 can be used to grind and polish the crucible. By adjusting the position between the two grinding rollers 26, the grinding depth of the crucible can be accurately controlled to ensure the grinding thickness of the crucible wall. During the grinding process, the inner grinding roller 26 rotates, which drives the bevel gear 40 to rotate via sprocket 2 41, chain 43, and sprocket 1 39. This drives gear 1 38 to rotate, and under the action of gear 1 38 and the rack, the push frame 35 descends. Under the action of the return spring 37, the push frame 35 rises again. This causes the piston 34 to move up and down via the push frame 35, which in turn agitates the airflow in the blower 1 28 and blower 2 29. The airflow is then ejected through multiple air holes 1 30 and acts on the crucible. On the inner and outer walls, this avoids the damage to the grinding roller 26 caused by dust adhesion during the grinding process, which would reduce the service life of the grinding roller 26. After grinding, the two grinding rollers 26 are driven to detach from the crucible by the electric push rod three 16, and then the arc-shaped clamping plate 14 is driven away from the crucible by the electric push rod two 13. Then, the crucible is removed from the placement tray 12 and placed on another conveyor according to the feeding method, thus completing the grinding and polishing of the crucible. The whole process is automated and does not require manual labor, which improves the grinding and polishing efficiency of the crucible.

[0025] Example 2, as Figure 4As shown, the present invention proposes an automated crucible production line, which, compared to Embodiment 1, further includes a dust removal mechanism mounted on a rotating assembly and driven by a dust pump 52 to collect grinding dust. The dust removal mechanism consists of a dust collection assembly and a dust filter assembly. The dust collection assembly includes a collection chamber formed on a dust collection disc 17, with multiple air holes 46 formed on the bottom inner wall of the collection chamber. A connecting pipe 48 is installed on the top of the dust collection disc 17, and the end of the connecting pipe 48 at the top of the dust collection disc 17 is made of flexible tubing to prevent interference with the suction. The lifting and lowering of the dust pan 17 has an impact. One end of the connecting pipe 48 is connected to the collection chamber. The dust filter assembly includes a dust collection cylinder 47 installed on the support frame 11. The dust collection cylinder 47 is connected to the other end of the connecting pipe 48. A filter plate 49 is installed on the dust collection cylinder 47. A dust suction pump 52 is installed on the dust collection cylinder 47. The air inlet of the dust suction pump 52 is connected to the dust collection cylinder 47. A collection cylinder 50 is provided on the dust collection cylinder 47. One side of the dust collection cylinder 47 is provided with an opening. A baffle 51 is installed in the opening. The baffle 51 is connected to the collection cylinder 50 by multiple bolts.

[0026] In this embodiment, when the grinding roller 26 is grinding, the dust pump 52 can be started. The dust generated during the grinding process can be absorbed and transported into the dust collection cylinder 47 through multiple air holes 46 and connecting pipe 48. The dust is filtered by the filter plate 49 and the filtered dust will fall into the collection cylinder 50, thereby completing the collection of dust during the grinding process and improving the protection of the working environment.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
