the workpieces are manually hoisted on the line and fixed on the centrifugal rotating gelling device, after all the workpieces arranged on the centrifugal rotating gelling device 3 are leveled, the centrifugal rotating gelling device drives the workpieces to rotate and heat the workpieces, and the automatic metering glue injection device 1 and the automatic material pulling and scraping device 2 move along the guide rail until the workpieces are completely heated. When the glue outlet protective tube 110 of the automatic metering glue injection device 1 is aligned with the workpiece on the centrifugal rotary glue injection device 3, glue injection is started, after the weighed glue is injected into the inner cavity of the workpiece, the glue outlet protective tube 110 is withdrawn, and the automatic metering glue injection device 1 is stopped after moving to the original position through the ground rail traveling device 4. And starting the automatic material pulling and scraping device 2, and pulling out the sizing material injected into the inner hole of the workpiece along the axis direction to ensure that the sizing material is uniformly distributed in the axis direction. The centrifugal rotating gelling device 3 is started, the workpiece which is injected with the sizing material starts to rotate, the sizing material is uniformly adhered to the inner wall of the inner cavity of the workpiece under the action of centrifugal force, meanwhile, the centrifugal rotating gelling device 3 starts to heat the rotating workpiece, after the workpiece rotates, is heated and dried, after all workpieces on the centrifugal rotating gelling device 3 are subjected to glue injection, material pulling, material scraping and gelling, the workpieces arranged on the centrifugal rotating gelling device 3 are manually disassembled, hoisted and taken off line.
