[0037] Specifically, the clamping block 74 can extend out of the through hole 63 .

[0038] When it is necessary to replace the first bubble pressing plate 8 and the second bubble pressing plate 11, the staff pulls the lifting block 76, and the lifting block 76 moves in the limiting groove 62, thereby driving the first connecting rod 71 to move, and then driving the second connecting rod 72 to move. The second connecting rod 72 pulls the connecting plate 73 to move, and the spring 75 is stretched, driving the clamping block 74 to shrink into the movable groove 61 along the through hole 63, thereby removing the first bubble pressing plate 8 and the second bubble pressing plate 11 from the connecting tube 6, and releasing the lifting block 76.

[0051] Working principle: When in use, the staff places the packaging box on the mold 2, and drives the first bubble pressing plate 8 to move through the first cylinder 5 to press the side wall of the packaging box, and drives the second bubble pressing plate 11 to move through the second cylinder 10 to press the top wall of the packaging box;

[0052] When the mold 2 needs to be replaced, the rotating wheel 44 is rotated to drive the bidirectional screw 42 to rotate, thereby driving the threaded blocks 43 to move away from each other in the slot 14, and the threaded blocks 43 drive the clamping plates 41 to move away from each other in the groove 3, so that the mold 2 to be replaced is loosened, so as to replace the mold 2 of the corresponding size, and then the rotating wheel 44 is rotated again, so that the clamping plates 41 clamp and fix the replaced mold 2 again, so as to realize the replacement of the mold 2;

[0053] When it is necessary to replace the first bubble pressing plate 8 and the second bubble pressing plate 11, the staff pulls the lifting block 76, and the lifting block 76 moves in the limiting groove 62, thereby driving the first connecting rod 71 to move, and then driving the second connecting rod 72 to move. The second connecting rod 72 pulls the connecting plate 73 to move, and the spring 75 is stretched, driving the clamping block 74 to shrink into the movable groove 61 along the through hole 63, thereby removing the first bubble pressing plate 8 and the second bubble pressing plate 11 from the connecting tube 6, and releasing the lifting block 76. Under the elastic force of the spring 75, the clamping block 74 extends out of the connecting tube 6, driving the connecting plate 73, the second connecting rod 72, the first connecting rod 71 and the lifting block 76 back to their original positions. Through the above steps, the first bubble pressing plate 8 and the second bubble pressing plate 11 can be replaced.
