Technical Field

[0001] This utility model relates to the field of plastic product processing technology, specifically a grinding device for processing plastic products. Background Technology

[0002] Plastic products are very common in daily life, such as plastic buckets. After injection molding, the outer and inner walls of plastic buckets usually need to be polished to make them smoother. Currently, this is usually done by workers holding sandpaper, which is inefficient, time-consuming and labor-intensive. Therefore, we have proposed a polishing device for plastic product processing to solve the above problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] like Figure 1-3As shown in the figure, a grinding device for processing plastic products according to one embodiment of the present invention includes a U-shaped base 1. A clamping assembly 2 for simultaneously clamping two plastic buckets is provided on the U-shaped base 1. The clamping assembly 2 is used to clamp the outer wall of one plastic bucket and the inner wall of the other plastic bucket. Columns 3 are fixed at the four corners of the top of the U-shaped base 1. A top plate 4 is fixed to the top of the four columns 3. Two cylinders 5 are symmetrically fixed to the top of the top plate 4. A horizontal plate 6 is slidably fitted onto the surface of the four columns 3. The ejector ends of the two cylinders 5 slide through the bottom of the top plate 4 and are fixedly connected to the top of the horizontal plate 6. Below the horizontal plate 6, a first grinding device for grinding the inner surface and rim of one of the plastic buckets is respectively provided. The first grinding component 7 and the second grinding component 8 are used to grind the outer surface of another plastic bucket. The first grinding component 7 includes a cylinder 701, the diameter of which is smaller than the inner diameter of the plastic bucket. A circular plate 702 is fixed to the top of the cylinder 701. A first sponge sandpaper 703 is fitted and fixed to the surface of the cylinder 701 and the circular plate 702. The first sponge sandpaper 703 is used to grind the inner bottom wall, inner side wall and top edge of the plastic bucket. The second grinding component 8 includes a cylindrical shell 801. A second sponge sandpaper 802 is fixed to the inner wall of the cylindrical shell 801. The second sponge sandpaper 802 is used to grind the outer side wall and bottom of the plastic bucket. A drive assembly 9 for driving the first grinding component 7 and the second grinding component 8 to rotate is provided on the top of the horizontal plate 6.

[0023] When grinding plastic buckets, the worker first places both buckets on the U-shaped base 1, with the opening of one bucket facing upwards and the opening of the other bucket facing downwards (i.e., upside down). Then, the clamping assembly 2 clamps and fixes the outer wall of one bucket and the inner wall of the other bucket. After fixing both buckets, the two cylinders 5 drive the horizontal plate 6 downwards, allowing the first grinding piece 7 to descend into the interior of one bucket and the second grinding piece 8 to descend into the exterior of the other bucket. Then, the drive assembly 9 rotates the first grinding piece 7 and the second grinding piece 8. In this way, the first sponge sandpaper 703 can grind the inner bottom wall, inner side wall, and top edge of one bucket, while the second sponge sandpaper 802 can grind the outer side wall and bottom of the other bucket. This grinding process is highly efficient, saving time and effort.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the clamping assembly 2 includes two support blocks 201 symmetrically fixed to the lower surface of the top of the U-shaped base 1. A first bidirectional screw 202 is rotatably connected to the side wall of one support block 201 via a bearing, and a second bidirectional screw 203 is rotatably connected to the side wall of the other support block 201 via a bearing. The first bidirectional screw 202 and the second bidirectional screw 203 are fixedly connected, and the thread directions on the surfaces of the first bidirectional screw 202 and the second bidirectional screw 203 are opposite. A first motor 204 is fixed to the lower surface of the U-shaped base 1, and the output shaft of the first motor 204 is fixedly connected to one end of the second bidirectional screw 203. A guide rod 205 is fixed between the two support blocks 201. Two first clamping plates 206 are symmetrically threaded onto the surface of the first bidirectional screw 202. Two first clamping plates 206 are slidably connected to the surface of the guide rod 205. The top of the U-shaped seat 1 has two symmetrical openings adapted to the first clamping plates 206. The tops of the two first clamping plates 206 slide through the openings and are fixed with first clamping blocks 207 for clamping the outer wall of the plastic bucket. The surface of the second bidirectional screw 203 is symmetrically threaded with two second clamping plates 208. The two second clamping plates 208 are slidably connected to the surface of the guide rod 205. The top of the U-shaped seat 1 has a clearance opening adapted to the second clamping plates 208. The tops of the two second clamping plates 208 slide through the clearance opening and are fixed with second clamping blocks 209 for clamping the inner wall of the plastic bucket. The surfaces of the first clamping blocks 207 and the second clamping blocks 209 are provided with anti-slip textures, which can achieve a good anti-slip effect.

[0025] When it is necessary to fix the two plastic buckets, the first motor 204 can be started. The first motor 204 can drive the first bidirectional screw 202 and the second bidirectional screw 203 to rotate. The first bidirectional screw 202 can drive the two first clamping plates 206 to move closer to the center. The two first clamping plates 206 can drive the two first clamping blocks 207 to move closer to the center, thereby clamping and fixing the outer wall of one of the plastic buckets. The second bidirectional screw 203 can drive the two second clamping plates 208 to move further outward. The two second clamping plates 208 can drive the two second clamping blocks 209 to move further outward, thereby clamping and fixing the inner wall of the other plastic bucket.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the drive assembly 9 includes a second motor 901 fixed to the top of the horizontal plate 6. Two support plates 902 are symmetrically fixed to the top of the horizontal plate 6. A rotating rod 903 is rotatably connected between the two support plates 902 via bearings. Two driving bevel gears 904 are symmetrically fitted and fixed to the surface of the rotating rod 903. Both driving bevel gears 904 are meshed with driven bevel gears 905. A rotating shaft 906 is fixed to the bottom of each of the driven bevel gears 905. Both rotating shafts 906 are rotatably connected to the horizontal plate 6 via bearings. The bottom end of one rotating shaft 906 is fixedly connected to the top center of the circular plate 702, and the bottom end of the other rotating shaft 906 is fixedly connected to the top center of the cylindrical shell 801. Circular blocks 907 are fitted and fixed to the surface of both rotating shafts 906. The bottoms of the two circular blocks 907 are attached to the top of the horizontal plate 6, which can stabilize the rotating shafts 906.

[0027] When it is necessary to drive the first grinding part 7 and the second grinding part 8 to rotate, the second motor 901 can be started. The second motor 901 can drive the rotating rod 903 to rotate, the rotating rod 903 can drive the two driving bevel gears 904 on its surface to rotate, the two driving bevel gears 904 can drive the two driven bevel gears 905 to rotate, the two driven bevel gears 905 can drive the two rotating shafts 906 to rotate, one of the rotating shafts 906 can drive the circular plate 702 to rotate, thereby driving the first sponge sandpaper 703 to rotate, and the other rotating shaft 906 can drive the cylindrical shell 801 to rotate, thereby driving the second sponge sandpaper 802 to rotate.
