A first elastic member 7 for pushing the mounting plate 6 close to the clamping disc 3 is provided on the first support plate 5. The grinding unit group 8 is provided on the mounting plate 6.

[0023] In the above embodiment, by driving the second driving gear 22 to rotate through the servo motor 21, the second driving gear 22 drives the rack 23 engaged with it to slide, so that the first support plate 5 slides along the height direction of the machine body 1, so that the grinding part group 8 on the mounting plate 6 can correspond to plastic shells of different heights. At the same time, the first elastic member 7 on the first support plate 5 can enable the grinding assembly to adapt to the height difference of the plastic shell during grinding.

[0024] Reference Figure 2 and Figure 3 As shown: The grinding part group 8 includes a positioning roller 9 and a grinding roller 10. The grinding rollers 10 are arranged on both sides of the positioning roller 9. A top rod facing the clamping disc 3 is integrally formed on the mounting plate 6. The positioning roller 9 is rotatably mounted on the top rod. Two sliding plates 11 sliding along the length direction of the machine body 1 are slidably connected to the mounting plate 6. The two sliding plates 11 are symmetrically arranged with the positioning roller 9 as the center. A plurality of the grinding rollers 10 are respectively rotatably mounted on the two sliding plates 11. A bidirectional driving cylinder for driving the two sliding plates 11 to approach or separate from each other is fixedly mounted on the mounting plate 6.

[0025] In the above embodiment, when the grinding assembly corresponds to the plastic shell, the positioning roller 9 pre-supports the edge of the plastic shell, so that a plurality of grinding rollers 10 arranged on both sides of the grinding roller 10 are attached to both sides of the edge of the plastic shell, so that the grinding rollers 10 grind the burrs at the edge of the plastic shell. By driving the two sliding plates 11 to approach or separate from each other through the bidirectional driving cylinder, the grinding rollers 10 on the two sliding plates 11 can adapt to plastic shells of different thicknesses.

[0026] Reference Figure 2 and Figure 3 As shown: A second support plate 12 in an L shape is integrally formed on one side of the mounting plate 6. A sliding plate 16 sliding along the length direction of the machine body 1 is slidably mounted on the second support plate 12. The driving motor 13 is fixedly mounted on the sliding plate 16 through bolts. A slot hole 17 is formed in the second support plate 12. A second elastic member 18 is arranged in the slot hole 17.

The first driving gear 14 drives a plurality of transmission gears 15 to rotate through a transmission belt, and then drives a plurality of grinding rollers 10 to rotate for grinding. When the two sliding plates 11 approach or move away from each other, the second elastic member 18 pushes the sliding plate 16, so that the transmission belt remains taut on the transmission gears 15 and the first driving gear 14.

[0028] Working principle:

[0029] The plastic housing is clamped by the clamping disc 3, and then the plastic housing is moved to the grinding assembly. The sliding clamping seat corresponds to the plastic housing. The servo motor 21 is started to drive the second driving gear 22 to rotate. The second driving gear 22 drives the rack 23 engaged therewith to slide, so that the first support plate 5 slides along the height direction of the machine body 1. The positioning roller 9 on the mounting plate 6 fits against the plastic housing, so as to position the grinding roller 10 at the edge of the plastic housing. Then, by starting the driving motor 13, the first driving gear 14 at the driving end of the driving motor 13 rotates. The first driving gear 14 drives a plurality of grinding rollers 10 to rotate through a transmission belt to grind the edge of the plastic housing. When the thickness of the plastic housing is different, the two sliding plates 11 are driven to approach or move away from each other by the bidirectional driving cylinder, so that the grinding rollers 10 on the two sliding plates 11 can adapt to plastic housings of different thicknesses. At the same time, the second elastic member 18 pushes the sliding plate 16, so that the transmission belt remains taut on the transmission gears 15 and the first driving gear 14. When the height of the edge of the plastic housing is different, the positioning roller 9 can support the edge of the plastic housing. At the same time, the first elastic member 7 pushes the mounting plate 6, so that the grinding assembly can adapt to the different heights of the edge of the plastic housing.
