[0018] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0019] like Figures 1 to 3As shown, the embodiment of the utility model preferably provides a capping device for a packaging machine, including a first connecting frame 1, on which a folding device is arranged, the folding device includes a longitudinal folding mechanism 2 and a transverse folding mechanism, the transverse folding mechanism includes connecting seats 31 symmetrically arranged on both sides of the first connecting frame 1, and second connecting frames 32 that can move laterally relative to them are respectively arranged on the two connecting seats 31, and a connecting structure 4 that can adjust and lock the relative distance between the two second connecting frames 32 is arranged between the connecting seat 31 and the second connecting frame 32, and first cylinders 5 are respectively arranged on the two second connecting frames 32, and the two first cylinders 5 are arranged opposite to each other and first pressure plates 6 are respectively arranged on their driving shafts.

[0020] Specifically, the first cylinder cooperates with the first pressure plate to make the two first pressure plates move relative to each other, so as to press and fold the two side covers of the packaging box respectively, thereby effectively avoiding the problem of deformation and damage of the packaging box cover caused by the forced guiding and pressing of the folding rod by the prior art; and the relative spacing between the two first cylinders is changed by the relative movement of the two second connecting frames, and the second connecting frame and the connecting seat are adjusted and locked by the connecting structure, so that it can be adaptively adjusted and installed according to the width of packaging boxes of different specifications.

[0021] Furthermore, the connection structure 4 includes a plurality of through holes 41 symmetrically arranged on both sides of the connection seat 31 and arranged in a transverse interval, and screw holes 42 are arranged on both sides of the second connection frame 32 corresponding to the through holes 41, and connecting screws (not shown in the figure) that can be threadedly connected with the screw holes 42 are arranged in the through holes 41. Specifically, the connecting screws are connected to different through holes and threadedly locked with the screw holes of the second connection frame, thereby changing the relative position of the second connection frame and the connection seat, thereby adjusting and locking the relative spacing between the two second connection frames.

[0022] Furthermore, the connecting seat 31 has a guide cavity (not shown) with a lower opening, and the second connecting frame 32 is movably disposed in the guide cavity (not shown) and can move laterally along the guide cavity (not shown). Specifically, the second connecting frame is movably disposed in the guide cavity, and the side walls of the second connecting frame contact the inner walls of the guide cavity to achieve the guided lateral movement of the second connecting frame.

[0023] Furthermore, the first pressing plate 6 is provided with a guide shaft 61, and the guide shaft 61 is plugged into the second connecting frame 32 through a linear bearing, so that the first pressing plate can be smoothly guided to move by pressing.

[0024] Furthermore, the telescopic driving direction of the first cylinder 5 is set at an inclined angle to the horizontal plane, thereby effectively driving the first pressing plate on the first cylinder to press downwardly on the left and right cover plates of the packaging box, so that the cover plates of the packaging box are folded in a flush and close relationship.

[0025] Furthermore, the longitudinal cover folding mechanism 2 includes a longitudinal retaining frame 21 disposed on the first connecting frame 1 and located between the two first pressing plates 6, a second pressing plate 22 rotatably disposed on the first connecting frame 1 and located at one end of the longitudinal retaining frame 21, and a second cylinder 23 for driving the second pressing plate 22 to flip. Specifically, the longitudinal retaining frame cooperates with the flipping of the second pressing plate to realize the sequential folding of the front and rear covers of the packaging box.

[0026] Furthermore, the middle and upper part of the second pressing plate 22 is hinged to the first connecting frame 1, the second connecting frame 32 is hinged with a first hinge seat 24, the second cylinder 23 is arranged on the first hinge seat 24, the driving shaft of the second cylinder 23 is provided with a second hinge seat 25, and the second hinge seat 25 is hinged to the upper end of the second pressing plate 22. Specifically, the first hinge seat and the second hinge seat cooperate with the second cylinder, so that when the second cylinder performs a telescopic action, it drives the second pressing plate to swing relative to the first connecting frame, and because the middle and upper part of the second pressing plate is hinged to the first connecting frame, the second cylinder connected to the upper end of the second pressing plate can quickly drive the second pressing plate to move in a large range with a small stroke, so as to meet the cover folding requirements of high-speed box sealing.
