When polishing and grinding are carried out on the interior of the pan, the pan is placed in the discharging device 2. Then, the pressing frame 5 is driven to move downwards through the adjusting structure 8, and in the process, the pressing frame 5 drives the second pressing wheel 77 arranged on one side of the base 7 through the first limiting rod 6 to press at the edge of the cooker. At this time, if the discharging device 2 rotates, the cookware is synchronously driven to rotate, and the rotation of the cookware further drives the second pressing wheel 77 to rotate, so that the cookware is effectively prevented from displacement in the rotation process. When polishing the outer surface of the pot, firstly, the pot is opened downwards and the edge of the pot is placed on the top of the second pressing wheel 77. When the adjusting structure 8 drives the pressing frame 5 to move downwards, the first limiting rod 6 drives the second pressing wheel 77 on one side of the second spline shaft 73 to move downwards through the base 7 and gradually approach the discharging device 2 until the bottom of the second pressing wheel 77 contacts with the top of the discharging device 2. At this time, the discharging device 2 forces the second pressing wheel 77 to move up along the second spline shaft 73 via the movable member 76 and gradually approach the first pressing wheel 75 until the bottom of the first pressing wheel 75 is pressed against the cooker. At this time, the discharging device 2 rotates to drive the second pressing wheel 77, and then the second pressing wheel 77 drives the cooker to rotate. Subsequently, the polishing mechanism 34 moves downwards and contacts with the cookware, so that the polishing mechanism 34 polishes and polishes the surface of the cookware, and the problem that the external surface of the cookware cannot be polished and polished due to the fact that the existing fixture can only fix the cookware from the outside is solved.

The sanding and polishing mechanism 34 is then mounted inside a splined bore 33 provided on the mobile frame 32. When polishing operation of the surface of the pot is performed, the sliding table 30 and the sliding seat 31 are matched with each other, the movable frame 32 is driven to move along the horizontal direction and the longitudinal direction at the same time, and the polishing mechanism 34 is driven to move synchronously. So that the sanding and polishing mechanism 34 can move closely following the curvature of the pan surface.
Referring to fig. 2 and 3, the polishing mechanism 34 includes a first spline shaft 341 capable of moving longitudinally along the inside of the spline hole 33, a polishing head 342 for polishing a pot is disposed at the bottom end of the first spline shaft 341, a boss 343 is disposed at the center of the first spline shaft 341, a first return spring 35 for driving the first spline shaft 341 to return is disposed outside the first spline shaft 341, and two ends of the first return spring 35 are respectively abutted to the boss 343 and the moving frame 32.

Further, in order to automatically return to the original state after the first spline shaft 341 completes the grinding work, the first return spring 35 is provided outside the first spline shaft 341. When the grinding operation is finished, the first return spring 35 pushes the first spline shaft 341 to return to the initial position along the preset path, so as to be ready for the next grinding operation.
When the automatic feeding device works, the pot is placed in the discharging device 2 when the inside of the pot is polished and polished. Subsequently, the pressing frame 5 is started to move downwards through the adjusting structure 8, and in the process, the pressing frame 5 drives the second pressing wheel 77 arranged on one side of the base 7 to be pressed at the edge of the cooker through the first limiting rod 6. At this time, if the discharging device 2 rotates, the cookware is synchronously driven to rotate, and the rotation of the cookware further drives the second pressing wheel 77 to rotate, so that the cookware is effectively prevented from displacement in the rotation process. When polishing the outer surface of the pot, firstly, the pot is opened downwards and the edge of the pot is placed on the top of the second pressing wheel 77. When the adjusting structure 8 drives the pressing frame 5 to move downwards, the first limiting rod 6 drives the second pressing wheel 77 on one side of the second spline shaft 73 to move downwards through the base 7 and gradually approach the discharging device 2 until the bottom of the second pressing wheel 77 contacts with the top of the discharging device 2. At this time, the discharging device 2 forces the second pressing wheel 77 to move up along the second spline shaft 73 via the movable member 76 and gradually approach the first pressing wheel 75 until the bottom of the first pressing wheel 75 is pressed against the cooker. At this time, the discharging device 2 rotates to drive the second pressing wheel 77, and then the second pressing wheel 77 drives the cooker to rotate. Subsequently, 3 drives the burnishing and polishing mechanism 34 downward and into contact with the surface of the pan, thereby causing the burnishing and polishing mechanism 34 to polish and polish the surface of the pan.
