Example 1
As shown in fig. 1, a packing box comprises an upper cover and a lower cover which have the same shape; a hinge part A1 and a buckling part A2 for closing the cover are arranged between the upper cover and the lower cover; the hinge part and the buckling part can be buckled respectively by pressure in the vertical direction between the upper cover and the lower cover.
As shown in fig. 2-4, a cover closing device for a packing box comprises a frame body 1, a mounting die 2 for placing a lower cover and an upper cover, wherein a support frame 3 is fixedly arranged on the frame body, and a first pressing piece 4, a second pressing piece 5 and a driving component for driving the first pressing piece and the second pressing piece to move up and down are respectively arranged on the support frame; the first pressing piece is positioned above the hinge part, and the second pressing piece is positioned above the buckle part; the first pressing piece and the second pressing piece respectively press the hinge part and the buckle part after moving downwards for a certain distance; the first pressing piece presses the hinge part before the second pressing piece presses the buckle part.
In the buckling process, the hinge part is buckled firstly and then the buckling part is buckled, so that the upper cover and the lower cover can be effectively buckled, and the buckling requirement that the buckling precision requirement of the hinge part is higher than that of the buckling part is met; when the hinge part and the buckling part are buckled at the same time, namely, the hinge part and the buckling part are stressed at the same time, the upper cover or the lower cover can be damaged due to the increase of local pressure of certain contact surfaces caused by the error of the positions of the upper cover and the lower cover; in addition, when the upper cover rotates to a certain extent in the buckling process, the force applied by the second pressing piece can be changed into an inclined direction from the vertical direction during buckling, so that the buckling part deforms in the inclined direction during buckling, and the buckling resistance is reduced; the situation that the hinge parts are misplaced and the upper cover and the lower cover cannot be normally buckled due to the fact that the buckling and buckling parts are buckled firstly is avoided, and effective buckling of the upper cover and the lower cover is guaranteed.
The driving part is a first cylinder 6 for driving the first pressing piece and a second cylinder 7 for driving the second pressing piece, and the first cylinder and the second cylinder are connected with an external air source; the frame is internally provided with a controller, the first cylinder and the second cylinder are connected with electromagnetic valves for controlling the lifting of the first cylinder and the second cylinder, and the electromagnetic valves are electrically connected with the controller. The first cylinder and the second cylinder are independently controlled, so that the compression sequence of the first compression piece and the second compression piece is ensured.
The hinge parts of the upper cover and the lower cover are two symmetrically arranged; the lower end of the first pressing piece is provided with a pressing head 41 with the same shape as the corresponding position of the hinge part; the extrusion head is tightly pressed on the hinge part when the first pressing piece is pressed down; so that the first pressing member applies an effective pressure to the hinge portion during pressing. The lower end of the second pressing piece is rotatably connected with a pressing wheel 51; the periphery of the compression wheel is fixedly connected with a flexible ring 52; when the second pressing piece presses the clamping part, the flexible ring is propped against the upper surface of the upper cover; the compression wheel and the flexible ring are arranged to disperse the pressure applied to the upper surface of the upper cover, so that the upper cover is prevented from being damaged due to overlarge local pressure, and the stress is ensured.
