[0021] In the present invention, the lubricating oil barrel is placed in the circular groove 9 of the rotating disk 7, and its upper end surface is flush with the upper end surface of the circular support ring 11 to ensure stable support of the barrel body. The sealing film 8 is conveyed to a specified position through a film body moving mechanism (including a guide roller 16 and a winding and unwinding mechanism not shown) and is ready for heat sealing. The motor 27 is started to rotate half a turn. When the motor 27 is started, its output shaft drives the second gear 30 to rotate. The second gear 30 meshes with the first gear 29, thereby driving the rotating shaft 28 and the rotating disk 7 to rotate, so that the barrel body rotates to the lower part of the heat sealing mechanism. The hydraulic expansion link 4 is started to drive the hollow plate 32 and the heating ring 34 to descend. At the same time, the ring 33 and the annular blade 36 also descend accordingly. When the annular blade 36 contacts the sealing film 8, due to the elastic action of the support spring 37, the annular blade 36 cuts the sealing film 8 to ensure the accuracy of the heat sealing position. The heating ring 34 heats the cut sealing film 8 to soften it and fit it on the barrel body to achieve film sealing. During the start-up process of the above-mentioned motor 27, the transmission 19 is driven to rotate through the pulley 20 and the transmission belt 21 at the same time. The output end of the transmission 19 drives the turntable 26 to rotate. Due to the eccentric connection between the turntable 26 and the connecting rod 31, the connecting rod 31 pushes the first piston 39 to slide back and forth in the piston cylinder 23. When the first piston 39 slides forward, external air is inhaled into the piston cylinder 23 through the first one-way port. When it slides backward, the gas is discharged into the right space of the rectangular box 12 through the first one-way pipe 25. Since the normally open solenoid valve of the second one-way port 24 is energized and sealed at this time, the gas will accumulate in the right space of the rectangular box 12 and push the second piston 40 to move leftward to compress the recovery spring 17. When the motor 27 is turned off, the normally open solenoid valve is de-energized and conducts. The second piston 40 moves rightward for a period of time (heat-sealing stage), and a one-way gas flow through the suction hole 35, the hollow plate 32, the filter box 5, the second one-way pipe 14 and the rectangular box 12 will be generated. This one-way gas flow can suck the toxic gas generated by heat-sealing into the filter box 5 for waste gas treatment. After the heat-sealing is completed, the motor 27 can be started to rotate half a turn again, and the barrel after heat-sealing the film will be rotated to the left part of the turntable 7, and the barrel can be taken down. The overall feeding and discharging operations are not under the hydraulic telescopic rod 4 and the heating ring 34, which improves the overall safety. It should be noted that the feeding and discharging operations can be carried out on the left side while the heat-sealing is carried out on the right side, which improves the overall continuity and efficiency.
