Description

Technical Field

[0001] This utility model relates to the field of mobile phone casing processing technology, specifically a casing grinding device for mobile phone casing processing. Background Technology

[0002] With the rapid development of science and technology, mobile phone cases have become increasingly diversified due to the increase in mobile phone brands and functions. Classified by material, mobile phone cases include PC cases, leather, silicone, cloth, hard plastic, leather cases, tempered glass metal cases, soft plastic, velvet, and silk cases. Mobile phone cases not only serve as decorative items, making the phone more attractive, but also protect it from drops, scratches, water, and shocks. During the production process, mobile phone casings inevitably produce excess parts. Manual cleaning is time-consuming, labor-intensive, and inefficient; therefore, a mobile phone casing polishing device is needed.

[0003] However, existing mobile phone casing polishing devices are not effective in handling waste during polishing and have low working efficiency; therefore, they do not meet current needs. In response, we propose a casing polishing device for mobile phone casing processing. Utility Model Content

[0004] The purpose of this utility model is to provide a shell grinding device for mobile phone shell processing, so as to solve the problems mentioned in the background art, such as the poor effect of waste disposal and low working efficiency of existing mobile phone shell grinding devices during grinding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shell polishing device for mobile phone shell processing, comprising a main body, a motor disposed on the upper surface of the main body, a working groove disposed on the outer side of the main body, a transmission chamber disposed on the inner side of the main body, a sun gear disposed on the inner side of the transmission chamber, a gear ring disposed on the inner wall of the transmission chamber, planetary gears uniformly disposed between the sun gear and the gear ring, a transmission shaft disposed on the inner side of the sun gear, a connecting shaft disposed on the inner side of the planetary gears, a connecting roller disposed at the lower end of the connecting shaft, sandpaper disposed on the outer surface of the connecting roller, positioning rods disposed on both sides inside the working groove, a limiting rubber block disposed on the outer side of one end of the positioning rod, an anti-slip groove disposed on the outer surface of the limiting rubber block, a cylinder disposed at the other end of the positioning rod, a dust suction pipe disposed on the inner surface of the lower end of the working groove, a collection plate disposed at one end of the dust suction pipe, a connecting plate disposed at the lower end of the transmission shaft, and a cleaning brush disposed on the outer surface of the connecting plate.

[0006] Preferably, a vacuum cleaner is provided between the suction pipe and the collection plate, and the collection plate is slidably connected to the main body.

[0007] Preferably, the lower surface of the working groove is provided with an annular groove, and the lower end of the connecting shaft is slidably connected to the annular groove.

[0008] Preferably, the planetary gear meshes with the sun gear and the ring gear, and the meshing point is coated with lubricating oil.

[0009] Preferably, the lower end of the motor is inserted into the inner side of the main body and fixed to the outer surface of the main body by screws.

[0010] Preferably, the inner surface of the limiting rubber block is completely in contact with one end of the positioning rod, and the limiting rubber block and the positioning rod are fixed by screws.

[0011] Preferably, the upper end of the connecting shaft is fully fitted with the inner surface of the planetary gear, and the connecting shaft and the planetary gear are fixed by welding.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a positioning rod with limiting rubber blocks, anti-slip grooves and a cylinder at both ends. The positioning rod can be adjusted by the cylinder to adapt to different sizes of mobile phone cases. The limiting rubber blocks and anti-slip grooves increase the positioning effect of the mobile phone case.

[0014] 2. After the phone case is installed, the motor is turned on. Through the sun gear, planetary gears, and gear ring set inside the transmission chamber, the planetary gear transmission allows the connecting shaft inside the planetary gears to rotate around the sun gear while rotating. This allows the sandpaper on the outside of the connecting shaft to evenly polish the case, reducing wear caused by prolonged use of the sandpaper on the same surface, improving the polishing effect, and enabling simultaneous polishing of multiple cases, thus increasing the device's working efficiency. During polishing, the connecting plate and cleaning brush at the lower end of the transmission shaft sweep the waste to the bottom of the working groove, where a vacuum pipe and collection plate collect and process the waste, further improving the device's working efficiency.

The lower end is provided with a connecting roller 5, and the outer surface of the connecting roller 5 is provided with sandpaper 6. The two sides inside the working groove 10 are provided with positioning rods 15. The outer side of one end of the positioning rod 15 is provided with a limiting rubber block 16, and the outer surface of the limiting rubber block 16 is provided with an anti-slip groove 17. The other end of the positioning rod 15 is provided with a cylinder 9. The inner surface of the lower end of the working groove 10 is provided with a dust suction pipe 7, and one end of the dust suction pipe 7 is provided with a collection plate 8. The lower end of the drive shaft 11 is provided with a connecting plate 18, and the outer surface of the connecting plate 18 is provided with a cleaning brush 19.

[0022] Furthermore, a vacuum cleaner is installed between the suction pipe 7 and the collection plate 8, and the collection plate 8 is slidably connected to the main body 1.

[0023] By adopting the above technical solution, it is convenient to recycle waste and the absorption effect of the suction pipe 7 on waste is increased.

[0024] Furthermore, the lower surface of the working groove 10 is provided with an annular groove, and the lower end of the connecting shaft 4 is slidably connected to the annular groove.

[0025] By adopting the above technical solution, the stability of the transmission of the connecting shaft 4 is increased, which is beneficial for sandpaper polishing.

[0026] Furthermore, the planetary gear 13 meshes with the sun gear 14 and the ring gear 12, and the meshing points are coated with lubricating oil.

[0027] By adopting the above technical solution, the smoothness of planetary gear transmission is increased, and the transmission effect of the device is improved.

[0028] Furthermore, the lower end of the motor 2 is inserted into the inner side of the main body 1 and fixed to the outer surface of the main body 1 by screws.

[0029] By adopting the above technical solution, the connection of motor 2 is strengthened and the working stability of motor 2 is improved.

[0030] Furthermore, the inner surface of the limiting rubber block 16 is completely in contact with one end of the positioning rod 15, and the limiting rubber block 16 and the positioning rod 15 are fixed by screws.

[0031] By adopting the above technical solution, the connection strength of the limiting rubber block 16 is increased, and the working strength of the limiting rubber block 16 is improved.

The limiting rubber blocks 16 and anti-slip grooves 17 enhance the positioning effect of the phone case. After the phone case is installed, the motor 2 is turned on. Through the sun gear 14, planetary gears 13, and gear ring 12 located inside the transmission chamber 3, the planetary gear transmission causes the connecting shaft 4 inside the planetary gear 13 to rotate on one side. Working around the sun gear 14 allows the sandpaper 6 on the outside of the connecting shaft 4 to evenly polish the housing, reducing wear caused by prolonged use of the same surface on the sandpaper 6, improving the polishing effect of the sandpaper 6 on the housing, and enabling simultaneous polishing of multiple housings, thus improving the working efficiency of the device. While polishing, the connecting plate 18 and cleaning brush 19 at the lower end of the drive shaft 11 can sweep the waste to the bottom of the working groove 10, and then use the suction pipe 7 and collection plate 8 to uniformly recycle the waste, improving the working effect of the device.
