In this specification, the schematic expressions of the above terms do not necessarily refer to the same solution or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more solutions or examples.

[0043] An embodiment of the present invention provides a chandelier fan, which includes a fan body 1, as Figure 1 shown. A fixing base 3 is installed above the fan body 1, and a chandelier body 2 is installed below. The fan body 1 includes two electric rotating sleeves 11. One end of the rotating sleeve 11 is provided with a plurality of card slots. The fan body 1 further includes a plurality of fan blades 12. The upper and lower sides of the fan blades 12 are respectively installed in the card slots on the two rotating sleeves 11. A connecting shaft is sleeved inside the rotating sleeve 11. The fixing base 3 is fixed to the upper end of the connecting shaft, and the chandelier body 2 is fixed to the lower end of the connecting shaft. The chandelier fan is connected to a plug through an electric wire, and the plug can be inserted into a socket built in the ceiling, eliminating the risk of electric shock for non-professionals when wiring. Moreover, since both the plug and the socket are embedded in the ceiling, it will not affect the beauty of the ceiling.

[0044] The fixing base 3 includes a base 31 and a top seat 32, as Figure 2 shown. The base 31 is fixed to the connecting shaft. A connecting cylinder 33 is fixed between the base 31 and the top seat 32. Vertical first sliding rails 34 are provided on both sides of the connecting cylinder 33. First sliders 35 are slidably arranged in the first sliding rails 34. A first connecting block 36 is fixed to the first slider 35. A slot 37 is provided on one side of the first connecting block 36.

[0045] An arc-shaped locking block 38 is installed in the slot 37. A driving head 39 is rotatably provided below the base 31. A lead screw 310 is fixed on the rotating shaft of the driving head 39. An installation hole is provided on the locking block 38. A damping ring is fixed in the installation hole. The damping ring can be a plastic ring or a rubber ring. The damping ring is sleeved on the lead screw 310. The upper end of the lead screw 310 penetrates through the top seat 32 and is provided with a nut 311.

[0046] The chandelier body 2 includes a reflector cup 21. As Figure 3 shown, a mounting plate 22 is fixed in the reflector cup 21. The mounting plate 22 is fixed to the lower end of the connecting shaft. A light source 23 is fixed below the mounting plate 22. An installation groove 211 is provided at the lower end of the reflector cup 21. The chandelier body 2 further includes a diffuser plate 24. A prismatic plate 25 is provided below the diffuser plate 24. The diffuser plate 24 and the prismatic plate 25 are both installed in the installation groove 211. The chandelier body 2 further includes a light shield 26. The light shield 26 is snap-fitted to the lower end of the installation groove 211.

[0047] As Figure 4 shown, the light of the traditional chandelier fan is refracted onto the fan. When the fan and the chandelier work simultaneously, it will cause dizziness. As Figure 5 shown, the light source 23 in the chandelier fan of the present invention is preferably an LED lamp board. The reflector cup 21 can effectively reflect the light emitted by the light source 23 to the light-emitting surface. The diffuser plate 24 can make the light-emitting surface emit light evenly. The prismatic plate 25 can make the light irradiate downward. The light shield 26 can prevent the light from being refracted onto the fan blades 12 and avoid the influence on the light when the fan blades 12 rotate, having a good anti-glare effect.

[0048] The leaf surface of the fan blade 12 is curved. As Figure 6 shown.

[0049] The installation method of the chandelier fan includes the following steps:

[0050] S1: Open an installation hole in the ceiling at the installation position, and pass the top seat 32 and the locking block 38 through the installation hole;

[0051] S2: Turn the driving head 39 to control the rotation of the lead screw 310, and drive the locking block 38 to open during the rotation process;

[0052] S3: When the locking block 38 contacts the edge of the slot 37, continue to control the rotation of the lead screw 310. The locking block 38 will no longer rotate and will move downward together with the first slider 35 until the locking block 38 locks the ceiling, realizing the installation of the chandelier fan.

[0053] The installation method of the chandelier fan of the present invention, compared with the traditional method of fixing the chandelier fan with screws, can not only reduce the number of drill holes, is convenient for installation, but also will not cause the entire chandelier fan to fall off due to the detachment of the screws, reducing the potential safety hazard.

[0054] A processing device for a fan blade, which is used to process the fan blade 12. The processing device includes a processing platform 4. As Figure 7 shown, a conveying mechanism 5 is provided at one end of the processing platform 4.

[0057] A first cylinder 613 is fixed below the tabletop of the processing platform 4. As Figure 9 、 Figure 10 shown, the output shaft of the first cylinder 613 penetrates the tabletop of the processing platform 4 and is fixed with a second driving box 614. A second motor 615 is fixed in the second driving box 614. The output shaft of the second motor 615 penetrates the top plate of the second driving box 614 and is fixed with a second grinding head 616. The second grinding head 616 corresponds to the first grinding head 612.

[0058] The clamping member includes symmetrically distributed second sliders 63, which slide in the second sliding rails 62. A horizontal guide rail 65 is fixed on the second sliders 63. An electric third slider 66 slides in the guide rail 65. A horizontal first electric telescopic rod 67 is vertically fixed on the third slider 66. A first clamping plate 68 is fixed on the output shaft of the first electric telescopic rod 67. The two first clamping plates 68 correspond to each other.

[0059] A vertical spring 64 is fixedly connected between the second slider 63 and the second sliding rail 62. In the natural state of the spring 64, the first clamping plate 68 is slightly higher than the upper surface of the conveyor belt on the belt conveyor.

[0060] The spraying device 7 includes a vertical bracket 71 fixed above the processing platform 4. A first horizontal bracket 72 and a second horizontal bracket 73 are fixed on the vertical bracket 71. The first horizontal bracket 72 is located below the second horizontal bracket 73. Automatic spraying devices 74 are fixed above the first horizontal bracket 72 and below the second horizontal bracket 73, and the two automatic spraying devices 74 correspond to each other.

[0061] The placing rack 9 includes symmetrically distributed vertical plates 91. Multiple layers of inclined support plates 92 are fixed on the vertical plates 91, and the support plates 92 are inclined towards the middle position between the two vertical plates 91.

[0062] The transfer device 8 includes a second cylinder 81 fixed below the tabletop of the processing platform 4. The output shaft of the second cylinder 81 penetrates through the tabletop of the processing platform 4 and is fixed with a third drive box 82. A third motor 83 is fixed inside the third drive box 82. The output shaft of the third motor 83 penetrates through the top plate of the third drive box 82 and is fixed with a second connecting block 84.

[0063] Second electric telescopic rods 85 are vertically fixed on both sides of the second connecting block 84. A third electric telescopic rod 86 is fixed on one side of the second electric telescopic rod 85. A horizontal second connecting rod 87 is vertically fixed on the output shaft of the third electric telescopic rod 86. A second clamping plate 88 is fixed on the second connecting rod 87, and the two second clamping plates 88 correspond to each other.

[0064] During use, the fan blade 12 to be processed is conveyed by the conveying mechanism 5. By starting the third slider 66, the two first clamping plates 68 are respectively moved to both sides of the fan blade 12 to be processed. By starting the first electric telescopic rod 67, the two first clamping plates 68 are controlled to move closer to clamp the fan blade 12. By starting the third slider 66, the fan blade 12 is moved to between the first grinding head 612 and the second grinding head 616. By starting the first cylinder 613, the second grinding head 616 is lifted, so that the first grinding head 612 and the second grinding head 616 are respectively in contact with the upper surface and the lower surface of the fan blade 12. Then, the first motor 611 and the second motor 615 are started to control the rotation of the first grinding head 612 and the second grinding head 616, and the upper and lower surfaces of the fan blade 12 are ground simultaneously. By controlling one of the first electric telescopic rods 67 to extend and the other first electric telescopic rod 67 to shorten, the grinding position can be adjusted in the direction perpendicular to the guide rail 65. By controlling the third slider 66, the grinding position can be adjusted in the direction parallel to the guide rail 65. Therefore, the grinding of the entire surface of the fan blade 12 can be realized. Since the blade surface of the fan blade 12 is curved, the clamping member will move up and down with the undulation of the surface of the fan blade 12 during the movement. Therefore, the grinding of the entire surface of the fan blade 12 can be realized without manually holding the fan blade 12.

[0065] The second cylinder 81, the third motor 83 and the third electric telescopic rod 86 cooperate to control the two second clamping plates 88 to move to both sides of the fan blade 12 respectively. By starting the second electric telescopic rod 85, the two second clamping plates 88 are controlled to clamp the fan blade 12, and then the first clamping plate 68 is controlled to release the fan blade 12. The third motor 83 and the third electric telescopic rod 86 cooperate to control the side edge of the fan blade 12 close to the conveying mechanism 5 to contact the edge of the first grinding head 612. By starting the first motor 611, the first grinding head 612 is controlled to rotate to grind the edge of the fan blade 12.

[0066] By controlling one of the second electric telescopic rods 85 to extend and the other second electric telescopic rod 85 to shorten, the position of the fan blade 12 is adjusted. By starting the third electric telescopic rod 86, the fan blade 12 is controlled to contact the first grinding head 612 for grinding at the new position. After one side edge is ground, the fan blade 12 is inserted between the first grinding head 612 and the second grinding head 616. Then the second clamping plate 88 is controlled to release the fan blade 12. By extending the first cylinder 613, the first grinding head 612 and the second grinding head 616 are controlled to clamp the fan blade 12. By starting the first motor 611 and the second motor 615, the fan blade 12 is controlled to rotate, and the edge to be ground is adjusted to face the conveying mechanism 5. Then the fan blade 12 is clamped by the second clamping plate 88 again, and the edge to be ground is ground until all the edges of the fan blade 12 are ground.

[0067] During the process of grinding the edge, the first clamping plate 68 can be controlled to clamp other fan blades 12 to be ground on the conveying mechanism 5. Then the side of the fan blade 12 away from the conveying mechanism 5 is controlled to contact the second grinding head 616, and the second grinding head 616 is controlled to rotate to grind its edge. After the edge of the fan blade 12 is ground and clamped by the first clamping plate 68, when the second clamping plate 88 clamps it later, its edge is no longer ground. Therefore, this processing device can grind the edges of two fan blades 12 simultaneously by the second grinding head 616 and the first grinding head 612, improving the grinding efficiency.

[0068] The fan blade 12 is clamped between the two automatic painting devices 74 by the two second clamping plates 88. Then the automatic painting devices 74 are started to paint the upper and lower surfaces of the fan blade 12 simultaneously. By controlling one of the second electric telescopic rods 85 to extend and the other second electric telescopic rod 85 to shorten, the painting position is adjusted in the direction perpendicular to the third electric telescopic rod 86. By starting the third electric telescopic rod 86, the painting position is adjusted in the direction parallel to the third electric telescopic rod 86. Therefore, the spraying device 7 can complete the painting of both sides of the fan blade 12 simultaneously.

[0069] After the painting is completed, the second cylinder 81, the third motor 83, and the third electric telescopic rod 86 cooperate to control the placement of the fan blade 12 on the placement rack 9 for drying. During placement, the two side edges of the fan blade 12 are respectively supported on two corresponding support plates 92. Since the support plates 92 are inclined, the painted surface of the fan blade 12 will not contact the support plates 92, preventing the paint on it from contaminating the support plates 92. By setting up the placement rack 9 to place the undried fan blade 12, the fan blade 12 does not need to be dried under the clamping of the transfer device 8, improving the work efficiency.
