[0021] A capping mechanism applicable to multiple sugar boxes, referring to Figures 1-3 , includes a conveying device and a capping device. The conveying device includes a frame 11 and a conveyor belt 12 arranged on the frame 11. The capping device includes a pedestal 21 slidably arranged on the frame 11. The pedestal 21 is located on the conveying path of the conveyor belt 12, and the conveyor belt 12 passes through the pedestal 21. A pressing plate 22 is arranged below the pedestal 21. A power pressing device 23 for driving the pressing plate 22 to press the packaging box is arranged on the pedestal 21. A driving device is connected to the pedestal 21, and the pedestal 21 can drive the pressing plate 22 to reciprocate along the conveying path under the action of the driving device.

[0022] Further, the driving device is a linear motor.

[0023] Further, a plurality of elastic members are arranged on the pressing plate 22. A connecting plate 3 is arranged at the lower end of the pedestal 21. The connecting plate 3 is provided with moving holes 4 corresponding to the elastic members. One end of each elastic member passes through the moving hole 4 and is connected with an anti-detachment cap 41.

[0024] Further, the elastic member includes a fixing rod 51 arranged on the pressing plate 22. A spring 52 is wound around the fixing rod 51, and one end of the spring 52 is connected to the connecting plate 3.

[0025] Further, sliding grooves 6 are respectively formed on both sides of the frame 11, and sliding blocks 7 which are slidably matched with the sliding grooves 6 are arranged on the pedestal 21.

[0026] The working principle of the utility model is as follows:

[0027] When it is necessary to close the circular candy box, at this time, the pedestal 21 remains stationary, the conveyor belt 12 is started, the inner cover is installed on the lower box, and then the upper cover is placed on the lower box. When the circular candy box is conveyed to the lower part of the pressing plate 22, at this time, the power pressing device 23 is started, and the power pressing device 23 drives the pressing plate 22 to move downward, so as to close and fasten the upper cover on the lower box. The power pressing device 23 described above can be realized by a driving cylinder.

[0028] When it is necessary to close the rectangular packaging iron box, the driving device is started, and the driving device drives the pedestal 21 to move on the frame 11 and reciprocate along the conveying path. At this time, it is necessary to keep the conveying speed of the conveyor belt 12 and the moving speed of the pedestal 21 similar or the same; the upper cover and the box body are placed on the conveyor belt 12 for conveying. During the reciprocating movement of the pedestal 21, the power pressing device 23 drives the pressing plate 22 to move downward, so as to close and fasten the upper cover on the box body; during the whole process, both the pedestal 21 and the conveyor belt 12 are in a moving state. After multiple experimental tests, only when both the pedestal 21 and the conveyor belt 12 are in a moving state, can the pressing plate 22 press down to successfully close the rectangular packaging iron box and prevent the upper cover and the box body from shifting; it is also found during the experiment that the circular candy box is also applicable to this closing mode, that is to say, when both the conveyor belt 12 and the pedestal 21 are in a moving state, the closing operation of the circular candy box can also be completed. As Embodiment 1, the driving device can be realized by a linear motor. The linear motor is used to drive the sliding block 7 on the pedestal 21 to move along the sliding groove 6, so as to realize the linear movement of the pedestal 21 on the frame 11. Since the linear motor belongs to a mature means in the technical field of the present invention, it is not shown in the drawings.

[0029] In the above technology, in order to prevent the pressing plate 22 from damaging the candy box, a connecting plate 3 is arranged between the pedestal 21 and the pressing plate 22, a fixing rod 51 is arranged on the pressing plate 22, a spring 52 is wound around the fixing rod 51, one end of the spring 52 is connected to the pressing plate 22, and the other end is connected to the connecting plate 3. With this setting, when the pressing plate 22 presses on the candy box, the pressing plate 22 moves upward, the spring 52 is in a compressed state, and the fixing rod 51 moves in the moving hole 4 on the connecting plate 3, thereby realizing elastic buffering and avoiding damage to the upper cover and even the whole packaging box caused by direct pressure capping. The anti - detachment cap 41 is provided to prevent the fixing rod 51 from detaching from the connecting plate 3 during the movement.

[0030] For the capping mechanism of the present application, when the conveyor belt conveys the candy boxes for capping operations, the pedestal can be switched between a moving state and a stationary state through the driving device. Thus, it can be applicable to the capping operations of various packaging boxes such as round candy boxes and rectangular iron packaging boxes, and has a wider scope of application.

[0031] Although the present utility model has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art from this disclosure that various changes or modifications can be made to the present utility model without departing from the principles and spirit scope of the present utility model defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used for explanation, rather than for limiting the present utility model, and the scope of protection is defined by the content of the claims.
