The transmission shaft 19 is rotatably sleeved inside the sleeve 4, and both ends are respectively connected to the bottom end of the coupling shaft 21 and the top end of the rotating shaft 17 through two universal joints 18 for torque transmission.

[0022] The transmission components include a horizontal shaft 25, a fifth gear 26, multiple sixth gears 27 and multiple seventh gears 28. The horizontal shaft 25 is horizontally rotatably sleeved inside the truss 6. Multiple seventh gears 28 are respectively fixedly sleeved on the bottom ends of the turntables 7.

The fifth gear 26 is fixedly sleeved on the end of the horizontal shaft 25. Multiple eighth gears 29 are fixedly sleeved on the main shaft 24. The multiple fifth gears 26 are respectively meshed and connected with the eighth gears 29.

[0023] The inside of the truss 6 is hollow, and multiple air holes 601 are horizontally opened at the end. Both ends of the multiple air holes 601 are respectively communicated with the inside of the truss 6 and the cavity 502. A conduit 30 is fixedly installed above the truss 6. A guide ring 31 is fixedly installed at the upper end of the conduit 30. An air outlet is opened on one side of the guide ring 31 facing the brake disc. The guide ring 31 is communicated with the conduit 30.

[0024] A first one-way valve 32 is fixedly sleeved on the side wall of the column 5. A second one-way valve 33 is fixedly installed inside the column 5. The conduction direction of the first one-way valve 32 is from the outside to the inside of the sliding cavity 501, and the conduction direction of the second one-way valve 33 is from the sliding cavity 501 to the inside of the cavity 502.

[0025] When using this device, the hanging frame mechanism is first in the loading position. The operator aligns the mounting holes of the brake discs that have completed the painting operation with the multiple inserting rods 8 respectively to realize the combination of the brake discs and the turntables 7. After the multiple sets of jig components are all filled with the painted brake discs, the next process is entered for air drying operation.

[0026] The power sliding table device 3 starts, causing the entire hanging mechanism to drive the brake disc to move. When it moves to the area of the diversion box 15, the second gear 16 meshes with the toothed plate 201. Under the interference of the toothed plate 201, the second gear 16 drives the rotating shaft 17 to rotate. The rotating shaft 17 drives the coupling shaft 21 to rotate through the transmission shaft 19 and the universal joint 18. The coupling shaft 21 drives the fourth gear 23, and the fourth gear 23 drives the first toothed ring 20 and the third gear 22 to rotate.

[0027] The first toothed ring 20 drives the column 5 to rotate. The column 5 drives multiple hanging frame mechanisms to rotate, cooperating with the ventilation operation of the fan device 14, and discharging air from the ventilation holes 152 on both sides of the diversion box 15. The column 5 drives the hanging frame mechanism to rotate, causing multiple brake discs to rotate, making the ventilation more uniform, so that the painted brake discs can dry in a short time, shortening the production cycle and improving production efficiency.

[0028] When moving in the diversion box 15, the top ball 11 rolls into contact with the pressing plate 151. Since the pressing plate 151 is wavy, the sealing block 10 slides up and down under the elastic force of the pressing plate 151 and the spring 12. The sealing block 10 drives two racks 13 to move up and down. The two racks 13 cause multiple first gears 9 to rotate reciprocally. At the same time, the rotation directions of the two first gears 9 are opposite, so that two pairs of trusses 6 rotate in the opposite direction. Cooperating with the rotation of the column 5, the multiple brake discs on both sides of the column 5 are tilted to form a torque converter propeller structure, thereby guiding the air flow up and down, cooperating with the horizontal ventilation, enabling the brake discs to receive air flow in the vertical direction, and further improving the air drying efficiency.

[0029] The third gear 22 rotates, driving the main shaft 24 to rotate, and the rotation direction is opposite to that of the column 5. Thus, multiple eighth gears 29 drive the corresponding fifth gears 26 to rotate. The fifth gears 26 drive the corresponding cross shafts 25 to rotate. The cross shafts 25 rotate through multiple sixth gears 27 on them. The sixth gears 27 drive the corresponding seventh gears 28 to rotate. The seventh gears 28 drive the turntable 7 to rotate. The turntable 7 rotates through the insertion rod 8, thereby driving the brake disc located on it to rotate. When the sealing block 10 moves upward, the space of the sliding cavity 501 at the bottom of the sealing block 10 becomes larger, and the first one-way valve 32 is conducted to inhale air. When the sealing block 10 moves downward, the space of the bottom sliding cavity 501 becomes smaller, and the second one-way valve 33 is conducted, enabling the air flow to enter the cavity 502, and then enter the inside of the truss 6 through multiple air holes 601, be discharged into the guide ring 31 through the conduit 30, and finally be discharged through the air outlet and blown onto the brake disc. Cooperating with the rotation of the brake disc, it further dries the brake disc more fully.

[0030] An unloading mechanism is provided at the output end of the diversion box 15. The unloading mechanism includes a limit component and a transfer component. The limit component includes a vertical frame 34 and a clamping block 35. The vertical frame 34 is vertically and fixedly installed on the base 1, and the clamping block 35 is fixedly installed at the bottom of the upper side of the vertical frame 34 and is inclined.

[0031] The transfer component includes a guide rail 36, a linear sliding device 37, a telescopic cylinder 38, a plurality of fork plates 39, a second gear ring 40, a motor 41 and a ninth gear 42. The guide rail 36 is horizontally and radially fixedly installed on the base 1. The linear sliding device 37 is slidably embedded on the guide rail 36. The telescopic cylinder 38 is vertically and rotatably installed on the linear sliding device 37. The motor 41 is fixedly installed on the side of the linear sliding device 37. A plurality of fork plates 39 are all horizontally and fixedly installed on the side of the telescopic cylinder 38 and are distributed up and down, corresponding to multiple groups of trusses 6 respectively. The second gear ring 40 is fixedly sleeved on the bottom of the telescopic cylinder 38. The ninth gear 42 is fixedly sleeved on the output shaft of the motor 41 and is meshed with the second gear ring 40.

[0032] After the air-drying operation is completed and after detaching from the diversion box 15, the second gear 16 disengages from the toothed plate 201, the column 5 stops rotating, and remains stationary under the interference of its mechanical friction with the sleeve 4. The truss 6 remains parallel to the straight section of the ring rail 2, moves to the bottom side of the vertical frame 34 and then stops. Under the action of the clamping block 35, the sealing block 10 moves downward, causing multiple trusses 6 to deflect, and multiple turntables 7 to be in a vertically upward state. The linear sliding device 37 moves, driving the telescopic cylinder 38 and multiple fork plates 39 to move. The multiple fork plates 39 are respectively inserted into the bottom sides of the corresponding brake discs. Then the telescopic cylinder 38 extends upward, causing multiple brake discs to simultaneously disengage from the insertion rods 8. Then the linear sliding device 37 slides in the reverse direction, driving multiple brake discs to simultaneously disengage from the hanging mechanism. Then the motor 41 operates, driving the second gear ring 40 to rotate through the ninth gear 42. The second gear ring 40 drives the telescopic cylinder 38 to deflect, causing the fork plates 39 to deflect towards the next working area for easy unloading. At the same time, the hanging mechanism moves along the ring rail 2 to the starting point, waiting for the state of the next batch of brake discs to perform the drying operation.

[0033] After the drying operation is completed, the unloading mechanism can be used to synchronously and efficiently unload multiple brake discs, facilitating the hanging mechanism to quickly perform the next cycle of drying operation and further improving the production efficiency.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
