Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of steel nail polishing, and specifically, to a polishing device and process for steel nail processing. Background Art

[0002] In the steel nail processing industry, polishing is a key process to improve the surface quality of steel nails. Its purpose is to remove rust stains and burrs on the surface of steel nails so that the surface finish meets the requirements for subsequent use. Due to advantages such as relatively simple operation and the ability to process steel nails in batches, drum-type polishing devices have become one of the commonly used equipment for steel nail polishing.

[0003] Drum-type polishing devices mainly work based on the principles of centrifugal motion and friction. When the drum rotates around its axis, materials such as steel nails, abrasives, and polishing agents inside the drum move in a circular motion along the inner wall of the drum under the action of centrifugal force and gravity, constantly colliding and rubbing against each other. Rust stains, burrs, and other impurities on the surface of the steel nails are gradually removed under the action of friction force. At the same time, the abrasives and polishing agents grind and polish the surface of the steel nails to make the surface of the steel nails reach the required finish.

[0004] However, most drum-type polishing devices rely only on the single rotation direction of the drum for stirring, resulting in a relatively single movement form of materials such as steel nails, abrasives, and polishing agents inside the drum. It is difficult for the steel nails to be fully mixed and contacted with the abrasives and polishing agents, leading to uneven polishing, which affects the removal effect of rust stains and burrs on the surface of the steel nails, and further affects the overall quality of the steel nails. Summary of the Invention

[0028] Referring to Figure 5 With Figure 7 , the reciprocating movement mechanism includes an adjusting disk 18, an adjusting rod 20, and a synchronous rotation mechanism. Two adjusting disks 18 are rotatably arranged on the inner bottom wall of the support housing 10. A rotating shaft 19 is rotatably arranged at the eccentric position of the adjusting disk 18.

[0029] Embodiment 2 What is supplemented and explained in Embodiment 2 of this application on the basis of Embodiment 1 is that a polishing process for steel nail processing includes the following steps: Step 1: Feeding. After adding steel nails, abrasives, and polishing agents into the drum 2 through the feeding bin 5, close the feeding control valve. Step 2: Rotate the drum 2. The operation of the first motor 9 can drive the second pulley 8 to rotate. At the same time, through the conduction of the belt, it drives the first pulley 7, the support ring 3, and the drum 2 to rotate. When the drum 2 rotates, the materials such as steel nails, abrasives, and polishing agents in the drum 2 move in a circular motion along the inner wall of the drum 2 under the action of centrifugal force and gravity, constantly colliding and rubbing against each other. Impurities such as rust stains and burrs on the surface of the steel nails are gradually removed under the action of friction force. At the same time, the abrasives and polishing agents grind and polish the surface of the steel nails. Step 3: First stirring. The operation of the second motor 17 can drive the driving prism 16 to rotate. At the same time, through the sliding fit between the driving prism 16 and the first gear 15, it drives the first gear 15 to rotate. Thus, through the meshing of the first gear 15 and the first toothed ring 14, it drives the stirring column to rotate. Thus, through the rotation of the stirring column, it drives the stirring rod 13 and the scraper 12 to stir the materials such as steel nails, abrasives, and polishing agents in the drum 2, thereby improving the polishing effect. Step 4: Second stirring. The operation of the third motor 23 can drive the third gear 22 to rotate. At the same time, through the meshing of the third gear 22 and the second gear 21, it drives the two second gears 21 and the two adjusting disks 18 to rotate synchronously. The rotation of the adjusting disk 18 can drive the rotating shaft 19 to move around the connecting rod. Thus, it can pull the support plate 11 and the stirring column to move reciprocally through the adjusting rod 20 and further stir the materials such as steel nails, abrasives, and polishing agents in the drum 2 through the stirring rod 13, thereby improving the polishing efficiency. Then, open the discharge control valve to discharge the materials.
