The suction of the sucker assembly 4 is released, the pushing cylinder 7 is started to drive the push rod 6 to move, the formed carton 1 is pushed and separated from the folding plate 811 and the folding rod 822, and finally the carton leaves the working frame 2.

The embodiment of the application provides an implementation principle of an automatic carton closing device, which comprises the following steps: the operator stacks a number of cartons 1 stacked into a carton in a loading chute body 31, the cartons 1 being blocked by a short bar 32 and a stop bar 33. Starting the driving piece 5, wherein the driving piece 5 drives the five vacuum chucks 41 to move along the length direction of the straight rod 61 towards the direction approaching to the feeding chute body 31; until the sucker assembly 4 contacts with the side plate 11 and is adsorbed on the side plate 11, the driving piece 5 drives the sucker assembly 4 to pull the carton 1 out of the feeding assembly 3, at the moment, the blocking block 34 separates the side plates 11 attached due to electrostatic adsorption, and the side plates of the carton 1 enclose a parallelogram; the rest cartons 1 are supplemented to one end of the feeding component 3, which is close to the working frame 2, under the action of gravity; the side plates 11 close to the push rod 6 are contacted with the arc-shaped rods 62, and are pushed by the arc-shaped rods 62 to rotate along the crease 12 at the joint of the two side plates 11 until the included angle between the two adjacent side plates 11 is a right angle. The driving piece 5 continues to drive the sucking disc assembly 4 to drive the formed carton 1 to move to the position above the turnover assembly 8 and then stops moving. The first turnover piece 81 is started, and the two wing plates 13 in the width direction of the feeding chute body 31 are turned over along the crease 12 into the carton 1; the second tucker 82 is then activated to flip the two flaps 13 along the length of the straight bar 61 along the crease 12 into the carton 1. Until the included angle between the wing plate 13 and the side plate 11 connected with the wing plate is right angle, the carton 1 completes the closing step. After the box closing is completed, the sucking disc component 4 releases the suction; the pushing cylinder 7 is started, and the pushing cylinder 7 drives the flat rod 61 to push the carton 1 to leave the working frame 2.

The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
