[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figure 1-2 , the present utility model provides a technical solution: an automatic barrel loading and unloading structure for the oil barrel of an oil injection machine, including a bottom plate 1, two sides of the upper end of the bottom plate 1 are fixedly connected with lifting cylinders 2, an oil barrel 3 is arranged between the two lifting cylinders 2, the upper ends of the piston rods of the two lifting cylinders 2 are jointly connected with a top plate 4, the middle part of the lower end of the top plate 4 is fixedly connected with an oil pressing plate 6 through four connecting rods 5, a sealing ring 7 is sleeved and fixedly connected around the oil pressing plate 6, a gear pump 8 is fixedly connected to the upper end of the oil pressing plate 6, an exhaust pipe 9 is fixedly connected to the pump body of the gear pump 8, a ball valve 10 is connected to the upper side wall of the upper end of the exhaust pipe 9 through a pipeline, and an intake air pipe 11 is fixedly connected to the upper end of the exhaust pipe 9. When in use, air is blown into the oil barrel 3 through the intake air pipe 11, facilitating the separation of the oil barrel 3 from the oil pressing plate 6.

[0016] The four connecting rods 5 are all vertically connected to the upper end of the oil pressing disc 6. The four connecting rods 5 are pairwise corresponding and surround the outside of the gear pump 8, which is convenient for stably lifting and lowering the oil pressing disc 6. The oil barrel 3 and the top plate 4 are located on the same center line. The oil barrel 3 is located at the central position between the two lifting cylinders 2, which is convenient for quickly lowering the oil pressing disc 6 into the oil barrel 3. The piston rod ends of the two lifting cylinders 2 are locked on the top plate 4 through screw sleeves, which is convenient for the lifting cylinders 2 to lift and lower the top plate 4. The oil pressing disc 6 is located at the upper inner part of the oil barrel 3, and the outer wall of the sealing ring 7 is closely attached to the inner wall of the oil barrel 3, which is convenient for sealing the gap between the oil pressing disc 6 and the oil barrel 3.

[0017] Specifically, when using the present utility model, place the oil barrel 3 on the bottom plate 1 and align it with the upper oil pressing disc 6. Start the lifting cylinder 2, and the lifting cylinder 2 lowers the oil pressing disc 6 and lowers the oil pressing disc 6 into the oil barrel 3. Open the ball valve 10, and the air between the oil barrel 3 and the oil pressing disc 6 is exhausted outward through the oil inlet of the gear pump 8, the exhaust pipe 9, the ball valve 10, and the intake air pipe 11 to empty the air in the oil barrel 3 and complete the barrel entry action. At the same time, start the solenoid valve to inflate the sealing ring 7, and seal the gap between the oil pressing disc 6 and the oil barrel 3 through the bulged sealing ring 7 to complete the sealing and maintain it. Start the gear pump 8 to start pumping oil. In the later stage when removing the barrel, the lifting cylinder 2 jacks up the top plate 4 to pull up the oil pressing disc 6 upward. At the same time, open the solenoid valve to empty the gas in the sealing ring 7, so that a gap is generated between the sealing ring 7 on the oil pressing disc 6 and the oil barrel 3. At the same time, open the ball valve 10, and the intake air pipe 11 blows air into the exhaust pipe 9 through the ball valve 10, that is, blows air into the oil barrel 3, and uses the air pressure to squeeze the oil barrel 3 off the oil pressing disc 6 to complete the barrel removal action.

[0018] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
