DETAILED DESCRIPTION

[0016] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application pertains.

[0017] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0018] like Figures 1-4 As shown, an egg tray stacking and shifting mechanism includes a stacking beam H200 that reciprocates under the control of swing arms H100 at both ends. Several egg tray gripping mechanisms H300 are located below the stacking beam. The ends of the stacking beam H200 are rotatably connected to the upper ends of the two swing arms. Stable transmission mechanisms H400 are located at both ends of the stacking beam to ensure that the beam maintains a positive working angle (i.e., the egg tray gripping mechanisms are always facing downward). The utility model discloses an egg tray stacking and shifting mechanism that clamps and shifts the egg trays when destacking the egg trays through reciprocating motion, and can simultaneously destacker multiple groups of egg trays. The mechanism has a short shifting stroke, is completed in one step, is convenient and practical, and has high efficiency. Furthermore, the arrangement of the stable transmission mechanism H400 ensures that the destacking beam H200 does not deflect during the reciprocating motion of the swing arm, and always maintains a positive working angle, that is, the egg tray clamping mechanism always faces downward, and can ensure that the egg trays are always in a horizontal state during the shifting process and do not tilt, thereby preventing the egg trays and eggs from falling, and ensuring stable and reliable operation.

[0019] In this embodiment, the lower end of the swing arm H100 is connected to a swing arm connecting shaft H500. The stabilizing transmission mechanism includes a first sprocket H410 disposed on the swing arm connecting shaft. The end of the destacking beam is provided with a swing shaft H210 rotatably connected to the upper end of the swing arm. The swing shaft is provided with a second sprocket H420. The first sprocket H410 and the second sprocket H420 are connected by a transmission chain H430 to ensure that the destacking beam maintains a positive working angle during the reciprocating motion of the swing arm. Because the destacking beam H200 and the swing arm H100 are connected by a swing shaft H210, the destacking beam H200 can rotate relative to the swing arm H100. Because multiple egg tray gripping mechanisms H300 are connected below the destacking beam, the center of gravity of the destacking beam structure is tilted downward, below the swing shaft, allowing the egg tray gripping mechanisms H300 to remain in a downward working position. However, to prevent the destacking beam H200 from swinging freely during movement, a stabilizing transmission mechanism H400 is added to ensure the stability of the destacking beam H200 during reciprocating motion, ensuring that it always maintains a positive working angle.

[0020] In the embodiment, the egg tray clamping mechanism H 300 comprises a connecting plate H 310 connected to the lower side of the unstacking beam, left and right egg tray clamping plates H 320 and H 330 hingedly connected to the connecting plate H 310 and capable of moving synchronously towards or away from each other, and a plurality of egg suction cups H 340 arranged between the left and right egg tray clamping plates.

[0021] In the embodiment, the lower side of the connecting plate H 310 is connected to a suction cup connecting plate through bolts, the lower side of the suction cup connecting plate is connected to a plurality of air distribution pipes, and the egg suction cups H 340 are arranged in an array, with the egg suction cups H 340 in the same column being connected to the same air distribution pipe.

[0022] In the embodiment, the unstacking beam H 200 is provided with a push-pull plate H 220 capable of sliding leftward and rightward relative to the unstacking beam H 200 and a cylinder H 230 for driving the push-pull plate H 220 to move back and forth, one end of the cylinder H 230 is hingedly connected to the unstacking beam H 200, and the other end is hingedly connected to the push-pull plate H 220; the hinge part of the right egg tray clamping plate H 330 is provided with an extension plate H 331 extending upward, a connecting rod H 240 is connected between the extension plate H 331 and the push-pull plate H 220, and a linkage rod H 350 is connected between the extension plate H 331 and the left egg tray clamping plate. When the cylinder H 230 drives the push-pull plate H 220 to slide leftward and rightward, the push-pull plate H 220 drives the right egg tray clamping plate H 330 to swing through the connecting rod H 240, and the right egg tray clamping plate H 330 drives the left egg tray clamping plate to move synchronously through the linkage rod H 350. In the specific implementation process, the connection mode of the left and right egg tray clamping plates can also be exchanged, which belongs to the same structure.

[0023] In the embodiment, the push-pull plate is provided with a plurality of horizontal guide grooves, and a pin connected to the unstacking beam H 200 is arranged in each horizontal guide groove, so as to realize the guiding effect of the push-pull plate and make it slide stably.

[0024] In the embodiment, in order to increase the buffering function of the entire egg tray clamping mechanism H 300, a connecting shaft H 360 penetrating the unstacking beam upward and capable of sliding up and down relative to the unstacking beam is fixedly connected to the upper end of the connecting plate H 310, a baffle H 361 clamped on the upper side of the unstacking beam is fixedly connected to the upper end of the connecting shaft H 360, and a spring H 370 is connected between the baffle H 361 and the unstacking beam.

Because there are many values, it is impossible to enumerate, therefore, the utility model discloses only part of values to illustrate the technical scheme of the utility model, and the above-mentioned enumerated values should not constitute the limitation of the protection scope of the utility model.

[0026] If the utility model discloses or involves mutually fixed connecting parts or structural members, then, except declaration, fixed connection can be understood as: detachably fixed connection (for example, bolt or screw connection), and can also be understood as: undetachable fixed connection (for example, riveting, welding), of course, the mutually fixed connection can also be replaced by integral structure (for example, integrally formed by using casting process) (except obviously cannot adopt integral forming process).
