[0007] A bag supply machine 5 is provided on the left side of the frame 1. When the bag taking suction cup 44 is in the lower position, the film bag B on the bag supply machine 5 can be sucked. A horizontally movable bag opening suction cup 8 is provided on the right side of the middle part of the frame 1. When the bag taking suction cup 44 is in the upper position, it is opposite to the bag opening suction cup 8, so that the film bag B can be opened.

[0008] The working principle of the utility model is:

[0009] A. The drum A on the conveyor 6 is transported to the top of the bracket 71, the bag taking cylinder 43 drives the bag taking suction cup 44 to descend vertically, sucks the bag opening of the film bag B on the bag supply machine 5 and returns to the initial position, the swing cylinder 41 drives the bag taking swing frame 42 and the bag taking suction cup 44 to drive the sucked film bag B to swing upward, the bag taking cylinder 43 then drives the bag taking suction cup 44 to drive the sucked film bag B to move horizontally to the right, and at the same time, the bag opening suction cup 8 moves horizontally to the left to suck the right bag opening of the film bag B, and then moves horizontally to the right to open the bag opening of the film bag B;

[0010] B. The lifting cylinder 3 drives the bag-supporting mechanism 2 to descend vertically, so that the lower part of the bag-supporting mechanism 2 extends into the film bag B. The motor 23 drives the turntable 27 to rotate, driving the bag-supporting plate 28 to move horizontally outward synchronously, so that the bag opening of the film bag B is opened to a circle larger than the outer diameter of the barrel A. The bag-taking suction cup 44 and the bag-opening suction cup 8 release the film bag B and return to the initial position. The bag-inserting cylinder 22 drives the bag-inserting cylinder 29 to extend vertically downward and open the bottom of the film bag B. The bag-inserting cylinder 22 unloads the force but keeps it stationary.

[0011] C. The clamping cylinder 73 drives the clamping plate 74 to move horizontally to the left, so that the barrel A is fixed between the baffle 75 and the clamping plate 74. The elevator 72 drives the bracket 71 and the clamped barrel A vertically upward, so that the inner bottom surface of the barrel A fits with the bottom of the film bag B. The elevator 72 continues to drive the bracket 71 and the clamped barrel A vertically upward, driving the bag insertion cylinder 29 and the bag insertion cylinder 22 vertically upward. The inner bottom surface of the barrel A always fits with the bottom of the film bag B. When the barrel A rises to the top of the opened circular bag mouth, its opened circular bag mouth is automatically folded to the outside of the barrel A.

[0012] D. The bag inserting cylinder 22 drives the bag inserting cylinder 29 to vertically upwardly separate from the bottom of the film bag B and return to the initial position. The motor 23 drives the turntable 27 to rotate in the opposite direction at a small angle, driving the bag support plate 28 to synchronously separate from the bag mouth of the film bag B. The elevator 72 drives the bracket 71 and the clamped barrel A to vertically downwardly return to the initial position, so that the barrel A falls onto the conveyor 6. The lifting cylinder 3 drives the bag support mechanism 2 to vertically upwardly return to the initial position. At the same time, the motor 23 drives the turntable 27 to rotate in the opposite direction, so that the bag support plate 28 returns to the initial position.

[0013] E. The clamping cylinder 73 drives the clamping plate 74 to move horizontally to the right and separate from the barrel A, and the barrel A continues to be transported to the subsequent unloading process.

[0014] The beneficial effects of the utility model are:

[0015] A. The bag opening of the film bag B is opened into a circle larger than the outer diameter of the drum A by using the bag opening mechanism 2, the bag insertion cylinder 29 is inserted into the film bag B and opens the bottom of the film bag B, and the drum lifting mechanism 7 is used to drive the drum A to rise above the opened circular bag opening, thereby realizing the automatic inner bagging and bag opening flanging actions of the drum A.

[0016] B. The six groups of bag-supporting plates 28 evenly distributed on the bag-supporting mechanism 2, as well as the working together of the turntable 27 and the connecting rod 26, can realize that the bag mouth of the film bag B is stretched into a circle to match the drum A, thereby improving the success rate of the bag mouth flanging, avoiding the waste of film bags, saving costs, and making the bag mouth after flanging neatly face upward outside the drum A. After the subsequent loading is completed, the automatic closing of the bag mouth is convenient, thereby improving the efficiency of the subsequent tying or sealing of the film bag B.

[0017] C. The motor 23 drives the turntable 27 to rotate in the horizontal plane to control the opening and closing size of the bag support plate 28, which can meet the bagging and bag turning requirements of various specifications of film bags B and matching drums A, thereby improving the practicability of the equipment.

[0018] D. When the elevator 72 drives the barrel A vertically upward, the bag inserting cylinder 22 unloads the force and the bag inserting cylinder 29 rises synchronously with the barrel A, so that the bottom of the film bag B always keeps in contact with the inner bottom surface of the barrel A, so that after the barrel A is bagged, its film bag B is completely in contact with the inner wall of the barrel, and there is no need for manual arrangement again, which improves work efficiency.

[0019] E. The bag supply machine 5, the bag taking mechanism 4 and the bag opening suction cup 8 are used to realize the automatic bag supply and bag opening of the film bag B when the inner bag is put on the drum A. The subsequent bag opening mechanism 2 opens the bag mouth of the film bag B and then releases the suction cup, thereby improving the success rate of bag opening. BRIEF DESCRIPTION OF THE DRAWINGS
