[0043] Example of a general-purpose crucible cleaning equipment:

[0044] like Figures 1-10 As shown, the general-purpose crucible cleaning equipment includes a four-column frame 1, a cleaning component 2, a rotating component 3, and a lifting component 4. The four-column frame 1 is mounted above the crucible opening 61. Positioning the four-column frame 1 above the crucible opening 61 facilitates the vertical entry of the cleaning component 2, supported by the four-column frame 1, into the crucible 6 to complete the cleaning.

[0045] To facilitate cleaning the inside of the crucible 6, the cleaning assembly 2 includes a brush plate 21 with steel wire bristles 22 clamped on it. The steel wire bristles 22 contact the inner wall of the crucible 6 to clean it. The steel wire bristles 22 can better remove residues from the crucible 6.

[0046] To achieve the rotation of the cleaning assembly 2, the rotating assembly 3 includes a rotary motor 31, a fixed base 32, multiple sleeves 34, and multiple rotating shafts 36 disposed within the sleeves 34. Both ends of each rotating shaft 36 are fixedly connected to external splines 37. The power output shaft of the rotary motor 31 is connected to the upper end of the uppermost rotating shaft 36 via an internal spline 38, and the lower end of the lowermost rotating shaft 36 is connected to the brush disc 21 to drive the brush disc 21 to rotate. Adjacent rotating shafts 36 are connected via internal splines 38. Both ends of each rotating shaft 36 are connected to the sleeves 34 via bearings 39. Both ends of each sleeve 34 are provided with flanges 35, and the upper flange 35 of the uppermost sleeve 34 is connected to the fixed base 32. The fixed base 32 has two symmetrical mounting holes, and adjacent sleeves 34 are connected via flanges 35 and bolts. The rotary motor 31 drives the rotating shafts 36 to rotate, thereby achieving the rotation of the brush disc 21. The sleeve is connected to the rotating shaft 36 via a bearing 39, which ensures that the rotation of the rotating shaft 36 will not be hindered when the sleeve is not rotating.

[0047] To allow the brush 21 to extend into and out of the crucible 6, the lifting assembly 4 includes a lifting motor 41, a first reducer 42, a second reducer 43, a third reducer 44, two lead screws 45, and two nuts 46. The output shaft of the lifting motor 41 is connected to the input end of the first reducer 42, and the output end of the first reducer 42 is connected to a transverse shaft 47. The two ends of the transverse shaft 47 are respectively connected to the input ends of the second reducer 43 and the third reducer 44. The output ends of the second reducer 43 and the third reducer 44 are respectively connected to lead screws 45. The nuts 46 are fixedly connected to the mounting holes. The nuts 46 cooperate with the lead screws 45 to drive the fixed seat 32 to move up and down. By setting two lead screws 45, the lifting of the fixed seat 32 is ensured to be horizontal, thereby ensuring that the extension and retraction of the brush 21 is horizontal.

[0048] While ensuring effective support, the material consumption for manufacturing the four-column frame 1 is saved. The four-column frame 1 includes a top plate 11, columns 12 and a bottom plate 13. The bottom plate 13 has a first opening 14 for the brush plate 21 to pass through. The first opening 14 facilitates the passage of the brush plate 21.

[0049] To reduce resistance during the lifting and lowering of the fixed base 32, sliding wheels 33 are provided at the four corners of the fixed base 32, and corresponding vertical slide rails 15 are provided on the column 12. The vertical slide rails 15 cooperate with the sliding wheels 33 to guide the lifting and lowering of the fixed base 32. At the same time, the numerical slide rails can also effectively ensure that the brush plate 21 can be lifted and lowered vertically.

[0050] like Figure 2 As shown, in order to facilitate the replacement of crucible 6, a crucible traveling trolley 5 is also provided below the above-mentioned four-column frame 1; the crucible traveling trolley 5 includes two horizontal rails 51 and a support plate 52. The horizontal rails 51 are provided with support columns 54, and the top of the support columns 54 is connected by a crossbar 53 to support the four-column frame 1.

[0051] Rollers 521 are provided on both sides of the support plate 52, and the rollers 521 slide in cooperation with the track 51. A second opening 522 is also provided in the middle of the support plate 52. The diameter of the second opening 522 is smaller than the outer diameter of the crucible opening 61 and larger than the outer diameter of the crucible body 62. The cooperation between the rollers 521 on the support plate 52 and the track 51 allows the support plate 52 to extend into and out of the four-column frame 1. Since the support plate 52 is used to support the crucible 6, the cooperation between the rollers 521 on the support plate 52 and the track 51 allows the crucible 6 to extend into and out of the four-column frame 1.

[0052] To reduce the need for manual alignment of the crucible 6, multiple positioning blocks 523 are provided around the second opening 522. The inner side of the positioning blocks is arc-shaped to limit the placement of the crucible 6.

[0053] To lock the position of the crucible 6 relative to the four-column frame 1, a first positioning plate 524 extends outward from the support plate 52. The first positioning plate 524 has a first positioning hole 525. A second positioning plate 55 is also provided on the corresponding support column 54, and the second positioning plate 55 has a second positioning hole 56. A positioning pin 58 passes through the first positioning hole 525 and the second positioning hole 56 to ensure that the center line of the crucible 6 on the support plate 52 coincides with the axis of rotation 36. This improves the cleaning effect of the crucible 6.

[0054] In order to achieve automatic locking of the crucible 6 position, a telescopic motor 57 is also included. The drive shaft of the telescopic motor 57 is connected to the positioning pin 58 to drive the positioning pin 58 to extend and retract.

[0055] To save on the length of track 51, the length of track 51 is equal to twice the length of support plate 52. This ratio just meets the requirements for taking out and placing crucible 6.

[0056] To enhance automation, the support plate 52 is equipped with a travel motor 526, which drives a gear 527. A rack 528 is located below the crossbar 53, and the gear 527 and rack 528 cooperate to allow the support plate 52 to slide on the track 51. The travel motor 526 drives the crucible 6 to extend and retract directly beneath the four-column frame 1, reducing manual intervention. Furthermore, for ease of control, a controller can be installed, electrically connected to the various motors to control their start and stop.

[0057] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
