Referring to fig. 9, the stacking mechanism is located on a side of the trolley 42 facing away from the conveying table 3, and the stacking mechanism includes a stacking rack 451, a stacking table 452, and a first lifting driving mechanism.

The stacking platform 452 is slidably mounted on the stacking rack 451 up and down, and the first lifting driving mechanism 45 is drivingly connected to the stacking platform 452 and is used for driving the stacking platform 452 to move up and down in the vertical direction.

Specifically, the first lifting driving mechanism 45 includes a lifting driving motor 453 and a transmission assembly, the transmission assembly includes a lower chain wheel, an upper chain wheel 454 and a transmission chain 456, the lifting driving motor 453 is installed at the bottom of the stacking rack 451, the lower chain wheel is connected with the lifting driving motor 453, the lifting driving motor 453 is used for driving the lower chain wheel to rotate, the upper chain wheel 454 is rotatably connected to the top of the stacking rack 451, the lower chain wheel and the upper chain wheel 454 are in transmission connection through the transmission chain 456, the lifting platform extends outwards to form an ear plate, and the transmission chain 456 is clamped in the ear plate.

After the paperboards are separated from the left conveying belt 43, the paperboards move to the stacking platform 452, the lower chain wheel is driven to rotate through the lifting driving motor 453, the lower chain wheel rotates to drive the transmission chain 456 to move, the transmission chain 456 drives the stacking platform 452 to move, so that the paperboards on the uppermost layer of the stacking platform 452 are close to the working surface of the left conveying belt 43, and therefore stacking of the paperboards is achieved.

In this embodiment, the first lifting driving mechanism 45 has two transmission assemblies, the two transmission assemblies are distributed on the stacking rack 451 at intervals along the transverse direction, and the upper chain wheels 454 of the two transmission assemblies are in transmission connection through a transmission shaft 457. In this manner, the stacking table 452 is supported from both sides of the stacking table 452 by the two transmission assemblies, respectively, so that the movement of the stacking table 452 is more smooth.

Further, a limiting plate 455 is further installed on the stacking table 452, and the limiting plate 455 is used for limiting the cardboard which is wrapped on the left conveyor belt 43, so that the stacking of the cardboard is more regular.

Fourth embodiment of a paperboard hemming device

This embodiment differs from the third embodiment of the board hemming device in that: in this embodiment, the cardboard device of borduring includes the feed mechanism that is used for carrying on the cardboard material loading. Referring to fig. 8 and 10, the feeding mechanism is located on a side of the trolley 42 away from the conveying table 3, and the feeding mechanism includes a bearing frame 461, a bearing table 462, a second lifting driving mechanism, and a pushing mechanism.

The bearing platform 462 is mounted on the bearing frame 461 in a vertically slidable manner, and the second lifting driving mechanism is in driving connection with the bearing platform 462 and is used for driving the bearing platform 462 to perform lifting movement in the vertical direction. The structure of the second lifting driving mechanism is the same as that of the first lifting driving mechanism, and for saving space, the second lifting driving mechanism is not described in detail in the application. In this way, the second lifting/lowering driving mechanism can drive the bearing platform 462 to perform lifting/lowering movement, so as to ensure that the uppermost paperboard of the bearing platform 462 is close to the working surface of the right conveyor belt 44.

The material pushing mechanism comprises a material pushing frame, a material pushing plate 464 and a material pushing cylinder 463, the material pushing frame is mounted on the bearing frame 461, a cylinder body end of the material pushing cylinder 463 is fixedly connected to the material pushing frame, a piston end of the material pushing cylinder 463 is connected with the material pushing plate 464, and the material pushing cylinder 463 is used for driving the material pushing plate 464 to horizontally move along the longitudinal direction so as to push the paper board on the uppermost layer of the bearing table 462 to the right conveying belt 44. In order to make the movement of the material pushing plate 464 more smooth, a guide rod 465 is installed on the material pushing frame, and the material pushing plate 464 is partially sleeved on the guide rod 465.

While the invention has been described with reference to specific embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration, rather than of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
