Description

Technical Field

[0001] The invention relates to packaging equipment, in particular to a turntable material suction mechanism. Background Art

[0002] A packaging machine is a special equipment that can package materials. One type of packaging machine is equipped with a turntable suction mechanism for sucking and transferring materials or packaging boxes. At present, the turntable suction mechanism on the market mainly includes a turntable, a suction nozzle is set on the turntable, and a lifting mechanism is set to drive the suction nozzle to lift and lower. When working, the suction nozzle is driven to rotate to the suction station by controlling the rotation of the turntable, and the lifting mechanism drives the suction nozzle to descend to suck the material or packaging box. The defects of this structure in actual use are: if the turntable is in a continuous rotation state during work, the suction of the suction nozzle and the material or packaging box needs to be completed in a very short time, the required suction force is very large, and it cannot be guaranteed that the material or packaging box can be stably adsorbed; if the turntable drives the suction nozzle to rotate to the suction station during work and stops for a certain period of time, wait for the suction nozzle to stably adsorb the material or packaging box before starting again, although the stability of the suction can be guaranteed, it will also cause the overall adsorption and transfer efficiency to deteriorate. At the same time, the frequent start and stop of the motor to drive the intermittent rotation will also cause the vibration and working noise of the equipment to increase. Summary of the invention

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a turntable material suction mechanism for solving the above-mentioned problem.

[0004] To this end, the present invention is implemented by adopting the following scheme:

When the turntable drives the movable frame to rotate to a material suction station, the pushing component drives the movable frame to move a distance along a trajectory in the opposite direction of the rotation of the turntable, so that the movable frame remains stationary relative to the material suction station for a certain period of time.

[0006] It also includes an annular guide frame with a notch, the notch is arranged corresponding to the suction station, a lifting frame is arranged at the notch of the annular guide frame, the lifting frame is connected to the lifting drive assembly, and the lifting seat has a first guide member that can extend into the annular guide frame or the lifting frame.

It also includes an annular guide frame 7 with a notch, the notch is set corresponding to the suction station 1, and a lifting frame 8 is set at the notch of the annular guide frame 7. The lifting frame 8 is connected to the lifting drive assembly. Specifically, the lifting drive assembly includes a second motor 3, the output end of the second motor 3 is connected to the rotating disk 5, the rotating disk 5 is eccentrically hinged to one end of the transmission arm 6, and the other end of the transmission arm 6 is hinged to the slide rail 4. A slide seat 31 that cooperates with the slide rail 4 is fixed on the frame, and the slide rail 4 is connected to the lifting seat 9. By controlling the second motor 3 to drive the rotating disk 5 to rotate, and through the transmission arm 6, the slide rail 4 and the lifting seat 9 can be driven to lift under the guidance of the slide seat 31. By setting the structure of the annular guide frame 7 and the lifting frame 8, the lifting drive assembly can be set separately at the suction station 1, and there is no need to set a lifting drive assembly for each lifting seat 9, which effectively simplifies the structure of the equipment, facilitates its production and assembly, and reduces production costs. The lifting seat 9 has a first guide member 23 that can extend into the annular guide frame 7 or the lifting frame 8. Specifically. The first guide member 23 is a first roller, and the annular guide frame 7 is provided with a first track groove 25 for the first roller to extend into, and the lifting frame 8 is provided with a second track groove 24 for the first roller to extend into. A pushing assembly is also provided corresponding to the movable frame 10. When the turntable 2 drives the movable frame 10 to rotate to the material suction station 1, the pushing assembly drives the movable frame 10 to move a distance along a trajectory in the opposite direction of the rotation of the turntable 2, so that the movable frame 10 remains stationary relative to the material suction station 1 for a certain period of time. Specifically, the pushing assembly includes a swing arm 17, the middle part of the swing arm 17 is rotatably arranged on the turntable 2, one end of the swing arm 17 is provided with a second roller 28, and the second roller 28 is arranged in the first guide groove 22 on the guide plate 21, and the other end of the swing arm 17 can push the movable frame 10 to move. Specifically, the other end of the swing arm 17 has a toggle groove 29, and a transmission shaft 16 is extended on the movable frame 10, and a first bearing 15 is mounted on the transmission shaft 16, and the first bearing 15 is stuck in the toggle groove 29. A spring 20 is connected between the movable frame 10 and the turntable 2 to achieve rapid reset of the movable frame 10 after it moves relative to the turntable.The turntable 2 is surrounded by a second guide groove 19 corresponding to each movable frame 10, and the movable frame 10 is provided with a third roller 27 that fits with the second guide groove 19. The movable frame 10 is also provided with a second bearing 18 and a third bearing 14. The second bearing 18 fits with the top surface of the turntable 2, and the third bearing 14 fits with the side arc surface of the turntable 2. The movable frame 10 is guided by the third roller 27, the second bearing 18 and the third bearing 14 to ensure that the movable frame 10 can only move in an arc trajectory along the turntable 2.

[0024] The working principle of the present invention is as follows: the material 32 is delivered to the suction station 1 through the conveyor belt, and the turntable 2 drives the movable frame 10 to rotate to the adsorption station. At this time, the first roller on the lifting seat 9 enters the second track groove 24 on the lifting frame 8, and then the lifting drive assembly drives the lifting frame 8 to descend, thereby driving the lifting seat 9 and the suction nozzle 12 to descend, so that the suction nozzle 12 can contact the material to perform the suction operation, and at the same time, the first guide groove 22 on the guide plate 21 will drive the second roller 28 to drive the swing arm 17 to swing, and the swing arm 17 will push the movable frame 10 to move a distance along the trajectory in the opposite direction of the rotation of the turntable 2, so that the movable frame 10 and The suction nozzle 12 remains stationary relative to the suction station 1 for a certain period of time, that is, the suction nozzle 12 can pause for a period of time when sucking materials to ensure the stability of suction. Then the lifting drive assembly will drive the lifting frame 8 to rise to the same height as the annular guide frame 7, and as the turntable 2 continues to rotate, the first guide groove 22 on the guide plate 21 will transmit the second roller 28 to drive the swing arm 17 and the movable frame 10 to reset, and the first roller on the lifting seat 9 will leave the second track groove 24 on the lifting frame 8 and enter the first track groove 25 on the annular guide frame 7, ensuring that the lifting seat 9 maintains the same height for transfer during the subsequent rotation of the turntable 2.

[0025] The structure of the present invention allows the adsorption component to have sufficient time to stop at the material absorption station to absorb materials or packaging boxes, thereby ensuring the stability of material absorption, and can also continuously rotate the turntable to ensure the overall material absorption and transfer efficiency.
