Technical Field

[0001] The utility model relates to the technical field of melamine tableware processing, in particular to a polishing machine used for melamine tableware. Background Art

[0002] Melamine tableware is a plastic product formed by heating and pressurizing melamine resin powder. It is also called imitation porcelain tableware. It resembles ceramic tableware because of its shiny and smooth surface and high hardness. This kind of tableware is non-toxic and odorless, and meets the national food hygiene standards and the US FDA hygiene standards. Therefore, it is widely used in the catering industry and children's catering industry. Melamine tableware needs to be polished during processing. Polishing can remove burrs and rough edges that may be generated in the production process of melamine tableware.

[0003] At present, when melamine tableware is polished, a large amount of melamine waste debris is often scattered on the surface of the workbench after the processing is completed. However, most existing polishing machines do not have the waste recycling function. These debris still contain melamine resin, which is a plastic material. If they are not recycled, they may become waste and cause potential pollution to the environment. Utility Model Content

Based on the embodiments in 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.

[0018] like Figure 1-4 As shown, a polishing machine for melamine tableware is characterized in that it includes a polishing table 1 and a polishing device 2 installed above the polishing table 1 for polishing the melamine tableware.

[0019] A fixing frame 3 is fixedly provided on the upper part of the left and right sides of the polishing table 1, and a threaded rod 4 is rotatably connected to the fixing frame 3. A motor 5 is also fixed to the fixing frame 3, and the output shaft of the motor 5 is fixedly connected to the rear end of the threaded rod 4;

[0020] The surface of the threaded rod 4 is sleeved with a threaded sleeve 6, which is threadedly matched with the threaded rod 4. A connecting rod 7 is fixed on the top of the threaded sleeve 6. A waste recovery plate 8 is slidably connected to the top of the polishing table 1. The connecting rod 7 is fixedly connected to the waste recovery plate 8, so that the rotation of the threaded rod 4 drives the waste recovery plate 8 to move forward and backward. A discharge plate 9 is connected to the front side of the polishing table 1;

[0021] A screening plate 10 is provided at the front side of the polishing table 1, and a waste recovery box 11 is provided below the screening plate 10; a support 12 is provided on both the left and right sides of the recovery box 11, and the support 12 is bolted to the front side of the polishing table 1, and a linkage structure 13 is provided above the support 12; a mounting plate 14 is slidably mounted on the top of the support 12, and the top of the mounting plate 14 is fixedly connected to the screening plate 10, and a plurality of springs 16 are installed on the rear end surface of the mounting plate 14, and the rear end of the spring 16 is fixedly connected to the surface of the polishing table 1;

[0022] A cam 15 is provided in front of the mounting plate 14 , and the cam 15 is connected to the linkage structure 13 , so that the cam 15 is rotated to drive the mounting plate 14 to move forward and backward.

[0023] A limiting groove 17 is provided at the bottom of the inner wall of the fixing frame 3 , and a limiting block 18 slidably connected to the inner wall of the limiting groove 17 is fixed at the bottom of the threaded sleeve 6 .

[0024] When the threaded rod 4 rotates, the limiting block 18 below will limit the threaded sleeve 6, so that the threaded sleeve 6 can only move in the front and rear directions on the surface of the threaded rod 4, so as to adjust the position of the waste recovery plate 8 above.

[0025] The linkage structure 13 includes a rotating rod 131 that penetrates the front side of the fixed frame 3, a first bevel gear 132 fixed to the front end of the rotating rod 131, a second bevel gear 133 that meshes with one side of the first bevel gear 132, and a connecting shaft 134 that is fixed to the surface of one side of the cam 15. The rear end of the rotating rod 131 extends to the interior of the fixed frame 3 and is fixedly connected to the front end of the threaded rod 4, and one end of the connecting shaft 134 is fixedly connected to the second bevel gear 133. When the staff turns on the motor 5, the rotating rod 131 will also start to rotate when the threaded rod 4 rotates, and the first bevel gear 132 drives the second bevel gear 133 to rotate, and the cam 15 on one side will rotate, and the cam 15 will contact the mounting plate 14 so that the screening plate 10 can shake back and forth.

[0026] The surface above the discharge plate 9 is inclined, and the screening plate 10 is located at the front side of the bottom of the discharge plate 9. The surface above the screening plate 10 is in contact with the bottom of the discharge plate 9 and is slidably connected to the discharge plate 9. In addition, the waste recovery box 11 is clamped with the screening plate 10, and a shielding plate is fixed to the front side of the top of the screening plate 10. When the waste recovery plate 8 pushes the melamine waste to the surface of the discharge plate 9, the melamine waste will directly slide onto the surface of the screening plate 10. When the screening plate 10 is shaken back and forth, the shielding plate can shield the melamine waste to prevent the melamine waste from falling from the surface of the screening plate 10. After the screening is completed, the staff can pull the waste recovery box 11 to separate the waste recovery box 11 from the screening plate 10 so as to carry out subsequent recycling of the melamine waste.

[0027] A guide wheel 19 is rotatably connected to the lower side of the mounting plate 14, a guide groove 20 is provided on the top surface of the support platform 12, and the guide wheel 19 is rollingly connected to the inner wall of the guide groove 20. When the cam 15 pushes the mounting plate 14 to move, the guide wheel 19 rolls inside the guide groove 20, thereby guiding the screening plate 10.

[0028] Working principle: When the staff polishes the surface of melamine tableware, the staff places the melamine tableware on the top of the polishing table 1, and then the staff operates the polishing equipment 2 above to polish the melamine tableware on the surface of the polishing table 1, and the debris generated during the polishing process falls directly on the top of the polishing table 1; after polishing, the staff removes the melamine tableware from the top of the polishing table 1, and at this time the staff turns on the motors 5 on both sides, so that the output shaft of the motor 5 drives the threaded rod 4 to rotate, and then the threaded sleeve 6 drives the waste recovery plate 8 above to move forward, and the melamine waste on the surface of the polishing table 1 is pushed to the surface of the unloading plate 9 through the waste recovery plate 8, and the melamine waste will fall on the surface of the screening plate 10. Then the staff controls the rotation direction of the output shaft of the motor 5, so that the waste recovery plate 8 returns to its original position. When the threaded rod 4 rotates, the first bevel gear 132 on the front side also rotates, so that the cam 15 rotates, and the cam 15 pushes the mounting plate 14 to move backward, so that the mounting plate 14 squeezes the spring 16 at the rear; with the continuous rotation of the cam 15 and the contraction and extension of the spring 16, the screening plate 10 swings back and forth to screen the melamine waste on the surface of the screening plate 10. After the staff finishes polishing the melamine tableware, they can remove the waste recovery box 11 and then recycle the collected melamine waste.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
