Description

Technical Field

[0001] The utility model relates to a rice bag packing device, in particular to a carton stripping mechanism. Background Art

[0002] Vacuum rice bags are of high value and need to be protected in cartons during transportation. Traditional manual packing is time-consuming and labor-intensive.

[0003] Although some automated rice packaging machines have appeared, such as the Chinese patent "A packaging device for rice packaging machine" authorization announcement number CN219565630U, the patent does not solve the problem that the flip plate of the carton is easily retracted, resulting in the rice bag being unable to be placed in the carton.

[0004] Although the applicant applied for a patent for a lifting and rotating box-lifting mechanism and its working method in 2022, with the authorization announcement number CN115231060A, and although it can solve the problem that the flip plate of the carton is easily retracted, resulting in the inability to put rice bags into the carton, each box-lifting plate is driven by a separate cylinder. As time goes by, the cylinders will produce inconsistent box-lifting actions due to different wear and other reasons. In order to allow each cylinder to move into place before proceeding to the next step, a certain time gap needs to be left to wait for the cylinder with delayed action (when the object of use is multiple groups of cartons, the time gap needs to be longer), thereby affecting work efficiency; and the current patent cannot be adjusted for cartons and rice bags of different sizes, thereby affecting the scope of application of the equipment.

[0026] To make the above features and advantages of the present invention more clearly understood, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0027] The carton lifting mechanism C of the present invention includes two groups of carton lifting mechanism lifting electric push rods C1 (cylinders can also be used) connected to the frame 1 and a carton lifting mechanism lifting frame C2 connected to the free ends of the carton lifting mechanism lifting electric push rods. The frame 1 is provided with a lifting frame guide rail C3 for guiding the carton lifting mechanism lifting frame C2 to slide vertically. The lifting frame C2 of the carton lifting mechanism is vertically guided by the lifting frame guide rail C3, and is lifted and lowered by the action of the carton lifting mechanism lifting electric push rods C1 (which is conducive to adapting to cartons of different heights and sizes).

[0028] A first transverse axis C4 and a second transverse axis C5 which are both rotatable are provided in parallel on the first and second sides of the lifting frame C2 of the box-lifting mechanism. A plurality of groups of box-lifting plates which rotate along with the transverse axis are provided on the first transverse axis C4 and the second transverse axis C5. The box-lifting plates include a side box-lifting plate C6 for keeping the side flipping plate K1 of the carton K in an open state and a front box-lifting plate C7 and a rear box-lifting plate C8 for keeping the front flipping plate K2 and the rear flipping plate K3 of the carton in an open state; that is, the first transverse axis C4 and the second transverse axis C5 independently have a plurality of groups of box-lifting plates. By providing a plurality of groups of box-lifting plates which rotate along with the transverse axis on the first and second transverse axes, the side box-lifting plates, the front box-lifting plates and the rear box-lifting plates can realize linkage action, thereby reducing the problem of inconsistent action response of the existing box-lifting plates (that is, through the linkage action of the side box-lifting plates, the front box-lifting plates and the rear box-lifting plates, the number of cylinders used is reduced, which is beneficial to reducing the time reserved for waiting for each cylinder to complete the action), which is beneficial to improving work efficiency.

[0029] A longitudinal sliding seat C9 is provided on the first side of the lifting frame C2 of the above-mentioned box-lifting mechanism. The first transverse axis C4 is rotatably hinged on the longitudinal sliding seat C9. The longitudinal sliding seat C9 is slidably connected to the longitudinal guide rail C10 on the lifting frame C2 of the box-lifting mechanism. The longitudinal sliding of the longitudinal sliding seat is driven by the first longitudinal cylinder C11, and the longitudinal sliding seat C9 is enabled to slide in the longitudinal direction (Y direction shown in the figure) through the first longitudinal cylinder C11 (which is conducive to adapting to cartons of different widths).

[0030] The longitudinal sliding seat C9 is connected to a swing cylinder C12 (which can also be an electric push cylinder), and the free end of the telescopic rod of the swing cylinder is fixedly connected to the first transverse axis C4 through a swing arm C13 (the first transverse axis C4 is rotatably hinged on the longitudinal sliding seat C9, one end of the swing arm C13 is connected to the free end of the telescopic rod of the swing cylinder, and the other end of the swing arm C13 is fixedly connected to the first transverse axis C4) to realize the rotation of the first transverse axis C4 and the side box-lifting plate C6 fixed on the first transverse axis C4 under the action of the swing cylinder C12. The figure takes 4 groups of cartons as an example, that is, four groups of side box-lifting plates C6 are provided on the first transverse axis C4 (used to keep the side flip plate on one side of the carton open).

[0031] The front box opening plate C7 (used to keep the front flip plate on the front side of the carton open) is fixedly connected to the first box opening longitudinal axis C14, which is rotatably connected to the first box opening longitudinal axis sleeve C15, which is fixedly connected to the longitudinal sliding seat C9. The end of the first box opening longitudinal axis is connected to the first transverse axis C4 (the first box opening longitudinal axis is arranged perpendicular or nearly perpendicular to the first transverse axis C4) through a universal joint C16 (which can be a crosshead universal joint capable of realizing vertical power transmission). When the first transverse axis C4 rotates, the first box opening longitudinal axis C14 and the front box opening plate C7 can be driven to rotate through the universal joint C16, so that the front flip plate of the carton is in an open state. That is, the side box opening plate C6 and the front box opening plate C7 on the first side can be swung by the rotation of the first transverse axis C4, keeping the side flip plate and the front flip plate on the first side in an open state.

[0032] A transverse sliding seat C17 capable of transverse movement (in the X direction shown in the figure) is provided on the lifting frame C2 of the box-lifting mechanism. The transverse sliding seat C17 is slidably connected to the transverse guide rail on the lifting frame C2 of the box-lifting mechanism. The transverse sliding seat C17 is driven by the first transverse cylinder C19, that is, under the action of the first transverse cylinder C19, the transverse sliding seat C17 moves transversely (which is conducive to adapting to cartons of different lengths); the second transverse axis C5 is rotatably hinged on the transverse sliding seat C17, and the transverse sliding seat C17 is provided with a rotating cylinder C20 capable of driving the second transverse axis C5 to rotate. Several groups of side box-lifting plates are provided on the second transverse axis C5. Through the action of the rotating cylinder C20, the second transverse axis C5 and the side box-lifting plates on the second side are rotated, so that the second side flip plate of the carton remains in an open state.

[0033] The rear box plate C8 is fixedly connected to the second box longitudinal axis C21, and the second box longitudinal axis C21 is rotatably connected to the second box longitudinal axis sleeve C22. The second box longitudinal axis sleeve C22 is fixedly connected to the transverse sliding seat C17. The end of the second box longitudinal axis C21 is connected to the second transverse axis C5 (the second box longitudinal axis C21 is arranged perpendicular or nearly perpendicular to the second transverse axis C5) through a universal joint C16 (which can be a crosshead universal joint capable of realizing vertical power transmission). When the second transverse axis C5 rotates, the second box longitudinal axis C21 and the rear box plate C8 are driven to rotate through the universal joint C16, so that the rear flip plate of the carton is in an open state; that is, the side box plates and the rear box plate C8 on the second side can be swung by the rotation of the second transverse axis C5, so that the side flip plate and the rear flip plate on the second side are kept in an open state.

[0034] The universal joint C16 can be a commercially available crosshead universal joint that can realize vertical power transmission, or the following specific structure: the universal joint C16 of the present application includes two C-shaped blocks C23 and a connecting block C24 connected between the two C-shaped blocks. The first end of the connecting block is hinged to a C-shaped block through a first pin shaft, and the second end of the connecting block is fixedly connected to the other C-shaped block. The openings of the two C-shaped blocks are rotatably hinged on the horizontal axis (the first horizontal axis or the second horizontal axis) or the longitudinal axis of the shift box. When the horizontal axis rotates, the two C-shaped blocks are driven to twist in turn, and then the longitudinal axis of the shift box is driven to rotate.

[0035] In order to limit the position of adjacent cartons, a guide box guardrail plate C25 is provided on the lifting frame C2 of the box stripping mechanism and below the first transverse axis and the second transverse axis (one of the guide box guardrail plates is fixed on the lifting frame C2 of the box stripping mechanism, and the other guide box guardrail plate is fixed on the longitudinal sliding seat C9). A plurality of windows C26 are provided on the guide box guardrail plate, and a rotatable box blocking plate C27 is rotatably hinged in each of the plurality of windows. Each box blocking plate is fixedly connected to a toggle arm C28, and each toggle arm is hingedly connected to a toggle push rod C29. The toggle push rod C2 9 is connected to the free end of the telescopic rod of the box-blocking telescopic cylinder C30 (it can also be an electric push cylinder). The cylinder body of the box-blocking telescopic cylinder is connected to the guide box guardrail plate C25. Under the action of the box-blocking telescopic cylinder C30, the push rod C29 moves horizontally (X direction in the figure), thereby driving the toggle arm C28 and the box-blocking plate C27 to swing. The swinging of the box-blocking plate C27 has two stations. One station is to swing into the window C26 without affecting the movement of the carton along the conveyor belt. The other station is to swing out of the window C26 to block the movement of the carton on the conveyor belt.

[0036] The utility model provides a plurality of groups of box-lifting plates rotating with the transverse axes on the first transverse axis and the second transverse axis. The box-lifting plates include side box-lifting plates for keeping the side turning plates of the carton in an open state and front box-lifting plates and rear box-lifting plates for keeping the front and rear turning plates of the carton in an open state, thereby realizing that the side box-lifting plates can realize linkage action with the front box-lifting plates and the rear box-lifting plates, thereby reducing the problem of inconsistent action response of the existing box-lifting plates and being conducive to improving work efficiency.
