Specific embodiments

[0042] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0043] Please refer to Figures 1-4, the present utility model provides the following technical solutions: a multi-station polishing machine, including a profile frame 1, a support disk 2 fixed on the top of the profile frame 1, a rotary grinding disk 3 rotatably installed on the upper part of the support disk 2, and a driving mechanism 5 for driving the rotary grinding disk 3 to rotate. It further includes a turnover loading mechanism 4. A plurality of turnover loading mechanisms 4 are fixedly arranged at equal intervals along the circumferential direction on the top of the profile frame 1. The turnover loading mechanism 4 includes a fixed seat 41, a bearing seat 411, a turnover telescopic arm 42, a fixed cylinder 43, a loading turntable 431, a vacuum tube 44, a rotary joint 45, a turnover cylinder 46, a rack 47, a first gear 48, and a second gear 49.

[0044] Further, as shown by Figure 1 and Figure 2 In this embodiment, the fixed seat 41 is fixed on the top of the profile frame 1. Two bearing seats 411 are symmetrically fixed on the top of the fixed seat 41. A rotating shaft 421 is fixed at the end of the turnover telescopic arm 42 and is rotatably connected between the two bearing seats 411. The fixed cylinder 43 is fixed to the free end of the turnover telescopic arm 42 by a fixing frame 422. The vacuum tube 44 is rotatably installed in the fixed cylinder 43 by a bearing. The rotary joint 45 and the loading turntable 431 are respectively fixed to the top and bottom ends of the vacuum tube 44. The turnover cylinder 46 is fixed on the profile frame 1. The rack 47 is fixed to the top end of the piston rod of the turnover cylinder 46. The first gear 48 is rotatably installed on the fixed seat 41 and meshes with the rack 47. The second gear 49 is fixed to the end of the rotating shaft 421 and meshes with the first gear 48. After adopting the above scheme, during use, first start the turnover cylinder 46. The piston rod of the turnover cylinder 46 pulls the rack 47 downward. The rack 47 drives the first gear 48. The first gear 48 drives the rotating shaft 421 to turn through the second gear 49, so that the turnover telescopic arm 42 drives the loading turntable 431 to turn outward to the horizontal state. Place the glass plate on the loading turntable 431 and adsorb and fix it. Then start the turnover cylinder 46 again, so that the loading turntable 431 drives the glass plate to rotate until the glass plate fits the rotary grinding disk 3. At this time, start the driving mechanism 5 to drive the rotary grinding disk 3 to rotate and polish the glass plate. The present utility model drives the turnover telescopic arm 42 to turn through the turnover cylinder 46, the rack 47, the first gear 48, and the second gear 49, with higher stability. And during the process of loading and unloading materials, the loading turntable 431 will be in a relatively stable state and will not generate longitudinal jitter resulting in the offset of the glass plate, improving safety.

[0045] It should be noted that during use, the rotary joint 45 is connected to a vacuum pump through a pipeline, and the vacuum pump is used to pump air to adsorb the glass plate on the loading turntable 431 to ensure the stability of the glass plate.

[0046] It should be noted that the vacuum tube 44 of the present utility model is rotatably installed. To avoid interfering with the rotation of the vacuum tube 44, a rotary joint 45 is designed to connect to the vacuum pump. Therefore, during use, an external power device is required to drive the rotary joint 45 to rotate, which is used to drive the material-carrying turntable 431 to rotate. Among them, the power device can adopt a motor or a scheme similar to the driving mechanism 5.

[0047] In addition, it should be further explained that the flipping telescopic arm 42 can be a telescopic structure composed of two hollow cylindrical members sleeved together, and bolts are used to adjust the telescopic length. The initial position of the material-carrying turntable 431 can be adjusted according to actual needs. Since the size of the glass plate is not large and the weight of the glass plate and the material-carrying turntable 431 is not high, in principle, replacing the flipping telescopic arm 42 with a cylinder or a hydraulic cylinder can also meet the working requirements.

[0048] Preferably, as shown by Figure 1 and Figure 2 in this embodiment, there are holes on the fixed seat 41. The first gear 48 is rotatably installed in the holes, the rack 47 passes through the holes, and the outer wall of the rack 47 abuts against the inner wall of the holes to ensure the stability of the rack 47.

The driving motor 51 is fixed on the profile frame 1, and a driving belt pulley 53 is fixed on the output shaft of the driving motor 51. The rotating column 52 is rotatably installed on the profile frame 1, the driven belt pulley 54 is fixed on the rotating column 52, and the transmission belt 55 is tensioned by the driving belt pulley 53 and the driven belt pulley 54. After adopting the above scheme, during use, the driving motor 51 is started to drive the driving belt pulley 53 to rotate. The driving belt pulley 53 uses the transmission belt 55 to drive the driven belt pulley 54 to rotate, and then drives the rotating grinding disc 3 to rotate through the rotation of the rotating column 52. It should be noted that in the present utility model, the rotating grinding disc 3 is fixed to the top of the rotating column 52 by a flange.

[0050] Preferably, as shown by Figure 1 、 Figure 3 and Figure 4As shown in the figure, in this embodiment, it further includes: a supporting plate 9, a fixing column 10, a sleeve 12, an adjusting screw 11 and an adjusting nut 13.

Adjusting nuts 13 are distributed on both sides of the supporting plate 9 and are installed on the adjusting screw 11 by means of thread screwing. After adopting the above solution, during use, rotating the adjusting nut 13 can change the position of the adjusting nut 13, thereby adjusting the opening and closing angle of the supporting plate 9, and it can be used to adjust the tension degree of the transmission belt 55.

[0051] Preferably, by Figure 1 As shown in the figure, in this embodiment, it further includes: a water baffle cylinder 6 and a vacuum drainage mechanism 7. The water baffle cylinder 6 is fixed at the top of the support disc 2 and sleeved around the rotary grinding disc 3. The vacuum drainage mechanism 7 is fixed on the profile frame 1, and the vacuum drainage mechanism 7 is communicated with the inner space of the water baffle cylinder 6 through a pipeline. The vacuum drainage mechanism 7 includes a vacuum tank, a water storage tank, a water delivery pipeline and valves, etc., to suck the grinding powder water inside the water baffle cylinder 6, and can also transport the grinding powder water inside the water baffle cylinder 6 when grinding the glass plate. The vacuum drainage mechanism 7 is an existing technology that has been fully disclosed in traditional polishing machines and will not be elaborated too much in this article.

[0052] Preferably, by Figure 1 As shown in the figure, in this embodiment, it further includes: an electric control cabinet 8. The electric control cabinet 8 is fixed on the top of the profile frame 1. The electric control cabinet 8 is connected to an electric power source to provide electric energy for the operation of the polishing machine and control the operation of the polishing machine.

[0053] Preferably, by Figure 1 As shown in the figure, in this embodiment, it further includes: a protective cover 14. The protective cover 14 is fixed on the top of the profile frame 1. The fixed seat 41 is located inside the protective cover 14, and a guiding sliding hole 141 is provided on the protective cover 14. The flipping telescopic arm 42 is located in the guiding sliding hole 141. When the flipping telescopic arm 42 flips to the horizontal state, it contacts the lower end of the guiding sliding hole 141. The protective cover 14 is used to shield the fixed seat 41, the rack 47, the first gear 48 and the second gear 49 to prevent staff from accidentally touching and causing safety accidents. The guiding sliding hole 141 is used to control the flipping range of the flipping telescopic arm 42.
