DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0022] Example 1: Reference Figure 1-Figure 5 The transparent ceramic orthodontic bracket injection molding adhesive mixing device includes a base plate 1, and also includes: a mixing barrel 11 installed on the base plate 1, and a mixing cage 165 is provided in the mixing barrel 11, which rotates on its own and rotates around the mixing barrel 11 in an inclined circle; a connecting shaft 17 is rotatably connected to the middle of the mixing barrel 11, and a rubber rod 171 is installed on the circumference of the connecting shaft 17. When the mixing cage 165 rotates on its own and rotates around the mixing barrel 11 in an inclined circle, the mixing cage 165 contacts the rubber rod 171, so that the connecting shaft 17 rotates, and when the mixing cage 165 contacts the rubber rod 171, the air hole 173 on the rubber rod 171 sprays air into the mixing barrel 11;

[0023] A mounting frame 12 is mounted on the bottom plate 1, a bevel gear 13 is fixedly connected to the mounting frame 12, a rotating shaft 141 is rotatably connected to the mounting frame 12, a connecting rod 162 is fixedly connected to the rotating shaft 141, one end of the connecting rod 162 is rotatably connected to the rotating shaft 161, a bracket 16 is arranged on the mounting frame 12, a ball head 164 is fixedly connected to the rotating shaft 161, the ball head 164 is movably connected to the bracket 16, a second gear 163 is fixedly connected to one end of the rotating shaft 161, and the second gear 163 is meshed with the bevel gear 13;

[0024] A motor 15 is installed on the mounting frame 12, and first gears 14 are fixedly connected to the output end of the motor 15 and the rotating shaft 141, and the two first gears 14 are meshed with each other;

[0025] A cavity 172 is formed in the rubber rod 171, and an air hole 173 is connected to the cavity 172. A one-way valve is installed in the air hole 173. An air passage 174 is formed on the connecting shaft 17, and the cavity 172 is connected to the air passage 174.

[0026] One end of the air passage 174 passes through the top of the connecting shaft 17, and one end of the air passage 174 is closed to prevent a large amount of gas in the cavity 172 from being discharged from one end of the air passage 174 when the stirring cage 165 hits the rubber rod 171;

[0027] When the device is in use, ceramic powder and binder to be mixed are added into the mixing barrel 11, and the motor 15 drives the rotating shaft 141 to rotate, so that the connecting rod 162 drives the rotating shaft 161 to rotate around the bevel gear 13, and the mixing cage 165 rotates around the circumference of the mixing barrel 11 during the rotation. Since the rotating shaft 161 is tilted, the mixing cage 165 rotates around the tilted circumference of the mixing barrel 11. Since the second gear 163 is installed at one end of the rotating shaft 161, the rotating shaft 161 can rotate on its own while rotating around the tilted circumference of the mixing barrel 11, thereby fully stirring the mixture in the mixing barrel 11.

[0028] While the stirring cage 165 rotates and tilts, the stirring cage 165 will hit the rubber rod 171. Since the rubber rod 171 is provided with a cavity 172 and the rubber rod 171 is soft, when the stirring cage 165 hits the rubber rod 171, the gas in the cavity 172 will be squeezed out through the air hole 173 and discharged into the mixture in the stirring barrel 11, thereby further improving the stirring effect.

[0029] Example 2: Reference Figure 4 The transparent ceramic orthodontic bracket injection molding adhesive mixing device is basically the same as that of Example 1, and furthermore: the end of the connecting shaft 17 is rotatably connected to the air pipe 18.

[0030] In this embodiment, the gas supply method in the air hole 173 can also be connected to the connecting shaft 17 through an external air pipe 18, and air is supplied to the air channel 174 in the connecting shaft 17 through the external air pipe 18, so that the gas can be continuously ejected from the air hole 173.

[0031] Example 3: Reference Figure 2 , Figure 4 , a transparent ceramic orthodontic bracket injection molding adhesive preparation device, which is basically the same as that of Example 2, and furthermore: a stirring rod 175 is fixedly connected to the circumference of the connecting shaft 17, and the stirring rod 175 is located below the rubber rod 171;

[0032] The stirring rod 175 can stir the mixture in the stirring barrel 11 again when the connecting shaft 17 rotates, so that the stirring barrel 11 is fully stirred and the efficiency is effectively improved;

[0033] Secondly, the stirring rod 175 is longer than the rubber rod 171 , and the stirring cage 165 can also push the stirring rod 175 when rotating, so that the connecting shaft 17 rotates.

[0034] The utility model uses the stirring cage 165 to stir the mixture in the stirring barrel 11 while using the stirring cage 165 to hit the rubber rod 171. Since the rubber rod 171 is provided with a cavity 172 and the rubber rod 171 is soft, when the stirring cage 165 hits the rubber rod 171, the gas in the cavity 172 is squeezed out through the air hole 173 and discharged into the mixture in the stirring barrel 11, thereby further improving the stirring effect. At the same time, the stirring rod 175 can stir the mixture in the stirring barrel 11 again when the connecting shaft 17 rotates, so that the stirring barrel 11 is fully stirred and the efficiency is effectively improved.

[0035] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the present invention can make some changes or modifications to equivalent embodiments of equivalent changes using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
