[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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 of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] A projector lens edge grinding device, as Figures 1 - 5As shown in the figure, it includes a chassis 1, a motor 2, a central shaft 3, centering wheels 4, a belt 5, a rear frame 6, a top shaft 7, torsion springs 8, folding plates 9, grinding wheels 10, a partition frame 11, a slag pan 12 and cleaning brushes 13. On the right side of the front part of the chassis 1, a motor 2 is connected. Both the front and rear parts of the chassis 1 are rotatably connected with a central shaft 3. The front central shaft 3 is connected to the output shaft of the motor 2. Seven centering wheels 4 are connected to the central shaft 3. A belt 5 is wound around the right parts of the central shafts 3 through pulleys. The rear part of the chassis 1 is connected with a rear frame 6. There are two handles on the rear frame 6 for easy handling. The upper part of the rear frame 6 is connected with a top shaft 7. Seven folding plates 9 are rotatably connected to the top shaft 7. There are two torsion springs 8, one on the left and one on the right, connecting each folding plate 9 to the top shaft 7. The lower parts of the folding plates 9 are rotatably connected with grinding wheels 10. Grinding patterns are provided on the grinding wheels 10 for easy grinding. Six partition frames 11 are rotatably connected between the central shafts 3. A slag pan 12 is connected to the chassis 1. Fourteen cleaning brushes 13 are connected to the slag pan 12.

[0021] When using the present utility model, first place the chassis 1 in the edge grinding area of the projector lens. Then rotate the folding plate 9, causing the torsion spring 8 to deform. After that, place multiple projector lenses to be ground between two adjacent centering wheels 4, one in the front and one in the rear. The partition frame 11 separates the multiple projector lenses. After the projector lenses are placed, let the torsion spring 8 return, driving the folding plate 9 to rotate, so that the grinding wheel 10 on the folding plate 9 contacts the projector lens. Then start the motor 2 to rotate the front central shaft 3. Through the transmission of the belt 5, the front and rear central shafts 3 rotate synchronously, causing the centering wheels 4 on the central shafts 3 to rotate, driving the projector lens to rotate. Through the contact and cooperation of the grinding wheel 10 with the projector lens, the edge of the projector lens is ground, thus achieving the effect of being able to grind multiple projector lenses simultaneously and improving the edge grinding efficiency of the projector lens. When grinding the edge of the projector lens, the projector lens contacts the cleaning brush 13 in the slag pan 12, so that the cleaning brush 13 sweeps the glass residues remaining on the edge of the projector lens, causing the glass residues to fall into the slag pan 12, avoiding affecting the edge grinding of the projector lens.
