In order to further expand the application range of the turnover mechanism, the turnover driving device 3 is further preferably connected with the turnover rack 1 in a sliding manner, and specifically, the turnover rack 1 is preferably provided with a driving guide rail cushion block 13 and a driving adjusting guide rail pair 14 mounted on the driving guide rail cushion block 13; the overturning driving device 3 further comprises a speed reducer fixing plate 33, and the speed reducer fixing plate 33 is installed on the driving adjustment guide rail pair 14; specifically, a screw rod stop block 15 is arranged on the side surface of the driving guide rail cushion block 13, and a screw rod 16 is arranged on the screw rod stop block 15; a nut plate 331 is mounted on the speed reducer fixing plate 33, and the nut plate 331 is connected with the lead screw 16 through a thread, so that the positions of the turnover driving device 3 and the turnover box device 2 in the horizontal direction can be adjusted through the lead screw 16, and the turnover box device 2 can be adjusted to a required position according to the use requirement; the reducer 32 is mounted on the outer side of the reducer fixing plate 33, and the output end of the reducer 33 is fixedly connected with the swing link 41.

In the present application, it is further preferable that a sliding groove is formed at the second end of the swing rod 41, a sliding block 411 is arranged in the sliding groove, and the sliding block 411 is in threaded connection with the swing rod 41 through a second adjusting screw 412; the overturning connecting rod 42 and the moving connecting rod 43 are both rotationally connected with the sliding block 412; specifically, in the present application, two rotating shafts are respectively disposed at two ends of the sliding block 411, both rotating shafts are disposed in parallel with the output shaft of the speed reducer 32, the rotating shaft located above is rotatably connected to the turning connecting rod 42, and the rotating shaft located below is rotatably connected to the moving connecting rod 43; the position of the sliding block 411 in the sliding slot 411 is adjusted by the second adjusting screw 412, so that the positions of the turnover connecting rod 42 and the moving connecting rod 43 are adjusted; when the slider 411 is closer to the output shaft of the speed reducer 32, the amount of horizontal displacement generated during the turning process is smaller, and vice versa.

For example, referring to fig. 8, the vertical central plane of the accommodating cavity in the flip box body 221 is a before flipping, the vertical central plane after flipping is B, and if the a plane and the B plane can always coincide, when the accommodating cavity is connected with the front and rear channels on the packaging machine, the AB plane coincides with the vertical central plane of the front and rear channels, that is, the central planes of all the channels are the same; after the production conversion and code conversion are carried out, the positions of the accommodating cavity before and after the overturning are required to be adjusted again so as to meet the requirements; the application provides a tilting mechanism adjusts jointly through lead screw 16 and second adjusting screw 412, can satisfy above-mentioned demand for the front and back passageway realizes seamless joint on tilting mechanism and the packagine machine.

According to the turnover mechanism provided by the utility model, the product groups which are regularly arranged in the packaging machine, namely, the products 6 to be packaged, are pushed into the turnover box body 221 through the push rod 5, the turnover box body 221 is driven by the turnover driving device 3 to horizontally move through the driving of the curved rod component 4, and meanwhile, the turnover mechanism is turned over by itself by 90 degrees; realizing the in-situ turnover of the product 6 to be packaged; then, the turned product 6 to be packaged is pushed out from the turnover box body 221 through the push handle 7, the pushed product 6 to be packaged enters the next process, and meanwhile, the turnover box body 221 returns to the original position under the action of the turnover driving device 3 and the curved rod assembly 4 to wait for the next turnover; this tilting mechanism is through treating packing product 6 and carry out the normal position upset, is favorable to simplifying the step that equipment for packing carries out the reprint and trades the sign indicating number to make tilting mechanism and packagine machine go up the front and back passageway and realize seamless joint.

The turnover mechanism can be applied to a single-channel packaging machine and can also be applied to a double-channel packaging machine; when the double-channel turnover mechanism is applied to a double-channel packaging machine, a scheme that two groups of turnover mechanisms are symmetrically arranged can be adopted.

When the packing form that does not overturn in the transformation of production, at first make the tilting mechanism that this application provided remain the state after the upset all the time, then change required upset box body 221 and compression board 2241, the width of passageway around the adjustment, the adjustment upset box body 221 position makes and holds the chamber and passageway one-to-one around with. When the turnover box is in work, a product 6 to be packaged is pushed into the turnover box body 221 by the push rod 5, then, compressed air is communicated in the cavity of the compression plate 2241, the product 6 to be packaged is pushed out of the turnover box body 221 by the push handle 7, and the turnover box body 221 only serves as a transition passage in the process.

Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and such changes and modifications will fall within the scope of the present invention.
