[0020] The following will be combined with the drawings of the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] according to Figure 1 , Figure 2 , Figure 3 As shown, a plastic shell grinding machine comprises: a grinding disc 1, on which an inner gear ring 2 is fixedly mounted;

[0022] The grinding disc 1 is provided with a planetary rotating mechanism 3, and the planetary rotating mechanism 3 is provided with a placement opening for storing a plastic shell 4;

[0023] The planetary rotating mechanism 3 is connected to an upper grinding mechanism 5 which rotates as the planetary rotating mechanism 3 rotates.

[0024] In a specific embodiment, the planetary rotation mechanism 3 includes a driving motor 31, a driving gear 32 and a transmission gear 33. The driving motor 31 is fixedly mounted on the grinding disc 1. The driving shaft of the driving motor 31 is fixedly connected to the driving gear 32. The transmission gear 33 is transmitted to the driving gear 32 and the inner ring 2. A placement opening for storing the plastic shell 4 is opened on the transmission gear 33.

[0025] It should be noted that there are multiple transmission gears 33 , and the multiple transmission gears 33 are distributed at equal intervals.

[0026] In a specific embodiment, a rolling element is provided at the bottom of the transmission gear 33 , and the rolling element is rollingly connected to the grinding disc 1 .

[0027] Specifically, the rolling element is a roller or a ball to increase the smoothness of the movement of the transmission gear 33 .

[0028] In a specific embodiment, the grinding mechanism 5 includes a grinding shell 51, a sleeve 52 and a positioning pin 53. The sleeve 52 is fixedly mounted on the driving gear 32. One end of the sleeve 52 slides through the grinding shell 51. A mounting ring 54 is fixedly mounted on the grinding shell 51. The insertion end of the positioning pin 53 slides into the interior of the mounting ring 54 and is blocked by the sleeve 52. A spray hole is opened on the sleeve 52.

[0029] Furthermore, a magnetic block adsorbed to the sleeve 52 is embedded in the T-shaped end of the positioning pin 53 .

[0030] The inner top surface and inner periphery of the polishing shell 51 are both provided with polishing surfaces, and the polishing surfaces are sandpaper surfaces.

[0031] Furthermore, a pull rope 55 is fixedly connected to the pulling end of the positioning pin 53 , a counterweight ball 56 is fixedly connected to one end of the pull rope 55 away from the positioning pin 53 , and a guide block 57 for the pull rope 55 to pass through is fixedly connected to the outer periphery of the mounting ring 54 .

[0032] It should be noted that the positioning pin 53 serves to limit the position of the grinding shell 51 . During rotation, the weighted ball 56 can pull the positioning pin 53 toward the sleeve 52 , thereby increasing the stability of positioning.

[0033] The positioning pin 53 is moved out to release the positioning of the polishing shell 51 so that the polishing shell 51 can be moved upward.

[0034] In a specific embodiment, one end of the sleeve 52 away from the driving gear 32 is fixedly connected to the air intake hopper 6 , and the fan blades 7 are fixedly mounted on the air intake hopper 6 .

[0035] It should be noted that when the driving motor 31 drives the driving gear 32 to rotate, the air inlet scoop 6 and the fan blades 7 can rotate, and the fan blades 7 can supply air to the inside of the sleeve 52, thereby blowing the particles generated inside and dispersing them out.

[0036] In the utility model, the plastic shell 4 is placed in the transmission gear 33. At this time, the bottom of the plastic shell 4 is in contact with the grinding disc 1. The grinding shell 51 is sleeved on the outer periphery and the top of the plastic shell 4. The driving motor 31 is started. The driving motor 31 drives the driving gear 32 to rotate. The driving gear 32 continuously drives the transmission gear 33 to rotate while rotating around the circumference of the inner gear ring 2. The bottom of the plastic shell 4 can be polished. Due to the differential speed of the driving gear 32 and the transmission gear 33, the grinding shell 51 can polish the outer periphery and the top of the plastic shell 4, thereby performing multi-faceted polishing to improve the polishing efficiency.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
