The processing of melon seeds requires processes such as cleaning, soaking, drying, cooking for flavor, seasoning, spreading and drying, and finally packing. Most of the existing melon seed packaging methods require manual bagging or manual-assisted feeding equipment for packaging, which is time-consuming and laborious and has low production efficiency. Although there are some automatic melon seed packaging machines on the market at present, their structures are relatively complex, and the production and maintenance costs are relatively high.

[0003] Based on the above, the purpose of the utility model is to provide an automatic melon seed packaging mechanism to solve the above problems. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an automatic melon seed packaging mechanism.

Feed hoppers are respectively arranged at the upper and lower ends of the material-taking disk, and melon seeds enter a storage cavity through the feed hoppers. By rotating the material-taking disk, multiple storage grooves intermittently take materials, and then the melon seeds are sent into a packaging bag through a funnel. Two clamps are further arranged to seal the packaging bag after the feeding is completed. With such a setting, the packaging equipment can achieve quantitative material taking, and can also automatically complete feeding and sealing, thereby improving production efficiency.

A first driving mechanism for driving the material taking disc 4 to rotate is provided on the mounting frame 1. A mounting plate 9 with one end slidably connected thereto is provided on the mounting frame 1. The other end of the mounting plate 9 is fixedly connected with a funnel 10. The funnel is located directly below the discharging port. Clamps 11 are rotatably provided on both sides of the mounting plate 9. A second driving mechanism for driving the funnel 10 to lift and driving the clamps 11 on both sides to clamp and seal the packaging bag is provided on the mounting frame 1.

[0024] Further: The second driving mechanism includes an electric push rod 12 fixedly connected to the mounting frame 1. The extending end of the electric push rod 12 is fixedly connected to the mounting plate 9. Rotating shafts 13 are rotatably connected to both sides of the mounting plate 9. The clamps 11 on both sides are respectively fixedly connected to the rotating shafts 13 on both sides. Driving gears 14 are fixedly connected to both rotating shafts 13 on both sides. Rack bars 15 with one end meshing with them are provided on both driving gears 14. The other end of the rack bar 15 is fixedly connected to the mounting frame 1.

[0025] Furthermore: The control mechanism includes a driving block 16 arranged in a frustum shape. A driving groove 17 for the driving block 16 to insert and move is provided on the material taking plate 4. A lead screw 18 is rotatably connected to the material taking plate 4. The driving block 16 is threadedly connected to the lead screw 18. A plurality of limiting rods 19 are fixedly connected to the driving block 16. Limiting grooves for the limiting rods 19 to pass through and move are formed on both the material taking plate 4 and the mounting box 3. A driven rod 20 with one end fixedly connected thereto is provided on the limiting plate 8. The other end of the driven rod 20 abuts against the inclined surface of the driving block 16. The driven rod 20 is slidably connected to the material taking plate 4.

[0026] Furthermore: A plurality of tension springs 21 with one end fixedly connected to the inner wall thereof are provided in the storage groove 7. The other end of the tension spring 21 is fixedly connected to the limiting plate 8.

[0027] Furthermore: The first driving mechanism is a motor 22.

[0028] Furthermore: A grooved wheel mechanism is provided between the motor 22 and the material taking plate 4. The grooved wheel mechanism includes a grooved wheel 23 and a driving disc 24. The grooved wheel 23 is fixedly connected to the material taking plate 4. The driving disc 24 is fixedly connected to the output shaft of the motor 22.

[0029] Working principle: When it is necessary to package melon seeds, the mounting frame of the packaging mechanism is installed on the ground beside the conveying mechanism. The conveying mechanism is a belt conveyor, or the mounting frame 1 can be fixedly connected to the side of the conveyor so that the funnel 10 is located directly above the conveying belt in the conveying mechanism. Then, the melon seeds are poured into the feeding hopper 2, and the melon seeds will slide into the storage groove 7 through the feeding port 5. The user can control the driving block 16 to move back and forth along the extension direction of the lead screw 18 by rotating the lead screw 18. During the movement of the driving block 16, the limiting plate 8 will be driven by the driven rod 20 to rise and fall in the storage groove, thereby controlling the storage amount of melon seeds in the storage groove 7 according to the needs, and further controlling the single packaging amount of melon seeds. A plurality of tension springs 21 can make the driven rod 20 always fit with the driving block 16, thereby making the adjustment of the storage amount of the storage groove 7 more stable.

[0030] Then, the unfolded packaging bags are intermittently conveyed towards the packaging mechanism by the conveyor. The user can unfold the packaging bags through the automatic bag opening mechanism and place the packaging bags on the conveyor by the manipulator. The automatic bag opening mechanism and the conveyor are both mature existing technologies, and the working principles of the two will not be elaborated here.

[0031] When the packaging bag moves to directly below the funnel 10, the funnel 10 is driven to descend by the electric push rod 12, so that the discharge pipe of the funnel 10 is inserted into the packaging bag. Then, the driving disk 24 is driven to rotate by the motor 22, and further the material taking disk 4 is driven to rotate intermittently in cooperation with the Geneva wheel 23. How to achieve intermittent rotation through the Geneva wheel 23 mechanism is a mature existing mechanism, and it will not be elaborated here. During the rotation of the material taking disk 4, the mounting box 3 can prevent the melon seeds in the storage slot 7 from spilling out until the storage slot 7 filled with melon seeds rotates to communicate with the discharge port 6. At this time, the melon seeds will slide into the packaging bag through the discharge port 6 and the funnel 10. Then, the funnel 10 is driven to rise by the electric push rod 12 until the funnel 10 is separated from the packaging bag. During this process, the two driving gears 14 on the mounting plate 9 will rise following the mounting plate 9. Since the positions of the two side racks 15 are fixed, the two side driving gears 14 will rotate driven by the racks 15, and then drive the clamp 11 to gather towards the middle through the rotating shaft 13, thereby squeezing and sealing the packaging bag. It should be noted that in this embodiment, a mounting bag with a self-sealing strip is selected. In other embodiments, if a packaging bag without an automatic sealing structure is used, a heat sealing mechanism can be installed on the two side clamps 11 to heat seal the packaging bag. The heat sealing mechanism is a mature existing technology and will not be elaborated here.

[0032] With such a setting, the packaging mechanism can control the material taking amount according to requirements and take materials quantitatively, and can also cooperate with the conveyor and the automatic bag opening machine to realize the automatic packaging of melon seeds without manual operation by workers, thereby improving the production efficiency.

[0033] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
