[0030] Furthermore, a push rod 8 is fixedly connected to one side of the surface of the fixed cylinder 4, and a fixedly connected bent connecting plate 7 is provided on the surface of the weighing cylinder 5. The other end of the connecting plate 7 passes through the fixed cylinder 4 and is fixedly connected to the push rod 8. Under the action of the push rod 8, the weighing cylinder 5 can be pushed a certain distance through the connecting plate 7 to bundle or discharge the leeks inside the symmetrical measuring cylinder 5.

[0031] A fixed groove is provided on one side of the rotating seat 2, and a push rod 2 17 is abutted in the fixed groove. A connecting rod 16 is hinged on one side of the fixed cylinder 4, and the other end of the connecting rod 16 is hinged on the push rod 2 17; the rotating table 1 rotates to drive the three fixed cylinders 4 to move to one side of each leek bundling mechanism, and cooperates with the rotating seat 2 to rotate horizontally along the connection of the rotating table 1, so that the moving direction of the weighing cylinder 5 is kept in the same straight line direction as the bundling mechanisms, so that the fixed cylinder 4 can cycle through automatic operations such as leek inversion, leek bundling and leek discharging, and the push rod 2 17 can shrink and change to make the hinged connecting rod 16 drive the fixed cylinder 4 to tilt, so that the weighing cylinder 5 faces the bundling slot 23, and under the action of the weighing cylinder 5, the roots of the leeks can be aligned, so that the weighing cylinder 5 can be moved to allow the leeks to be bundled to pass through the bundling slot 23.

[0032] Both ends of the fixed cylinder 4 are fixedly connected to the gathering mechanism 12, and an electric push rod is arranged inside the gathering mechanism 12. The other end of the gathering mechanism 12 is fixedly connected to the arc-shaped gathering clamping plate 11, and one side of the weighing cylinder 5 is provided with a dumping leek; when the leek is thrown into the weighing cylinder 5 from a high place, the leek inside the weighing cylinder 5 is relatively scattered, and when the weighing cylinder 5 is dumped, the scattered leek is as close to the inner wall of the weighing cylinder 5 as possible, and the leek is not concentrated and it is not convenient for the rubber band to penetrate. At this time, the electric push rod in the gathering mechanism 12 moves, which can drive the gathering clamping plate 11 to gather and concentrate the leek scattered during the dumping process, and concentrate the leek into a nearly cylindrical shape to facilitate the rubber band to penetrate the leek for bundling.

[0033] Limiting grooves 10 are provided at both ends of the inner wall of the fixed cylinder 4, and the surfaces of the limiting grooves 10 are against the limiting blocks 9, and the other end of the limiting blocks 9 is fixedly connected to the weighing cylinder 5; the limiting grooves 10 and the limiting blocks 9 limit the moving direction of the weighing cylinder 5 in the fixed cylinder 4 to ensure the stability of the weighing cylinder 5.

[0034] The crochet needle 22 comprises a triangular block, which is fixedly connected to a push rod four 21, and a cylindrical hook is fixedly connected to the surface of the triangular block; after the crochet needle 22 props up the rubber band and penetrates into the leek, the push rod four 21 is extended to make the tightened spring gradually shrink and fit the surface of the leek bundle 26, at which time the triangular block gradually squeezes the leek bundle 26, and the triangular block at one end of the crochet needle 22 gradually penetrates into the leek bundle 26 from the tip, and the rubber band is completely in contact with the leek bundle, and the crochet needle 22 can slide along the leek bundle 26 and leave the rubber band by contracting the push rod three 20, thereby completing the bundling of the leek.

[0035] A rubber band output mechanism 24 is arranged on one side of the positioning plate 18, and the rubber band output mechanism 24 comprises a vibration plate, a rubber band is arranged on the surface of the vibration plate, the bottom end of the vibration plate is fixedly connected to the vibrator, a rubber band output channel is arranged obliquely on one side of the edge of the vibration plate, and a hook is arranged at the bottom end of the output channel; before bundling the leeks, a certain amount of rubber bands are poured into the vibration plate, and the rubber bands can be moved in the vibration plate by the vibration of the vibrator. When the rubber bands enter the output channel under the action of the vibration, the vibration is stopped, and the rubber bands falling into the output channel are finally suspended on the surface of the hook, and then the positioning plate 18 is driven to move toward the rubber band output mechanism 24 under the action of the push rod three 19, and the four hooks 21 are pressed against the rubber bands from the inside, and the rubber bands can be propped up under the action of the push rod four 20 to automatically complete the process of pouring the rubber bands into the leeks.

[0036] An infrared receiver 27 is arranged on one side of the edge of the rotating seat 2, and an infrared transmitter 28 is arranged on the bottom of the fixed plate 18 and the bottom end of the discharge plate 24; while the fixed cylinder 4 is driven by the rotation of the rotating table 1 to continuously interact with various mechanisms, the rotation of the rotating table 1 cannot ensure that the tilting direction of the fixed cylinder 4 is in the same straight line with the various mechanisms, so an infrared signal is sent out by the infrared transmitter 27, and the rotating seat 2 is rotated according to whether the infrared receiver 28 receives the infrared signal to ensure that the fixed cylinder 4 can be aligned with the corresponding mechanism.

[0037] Specifically, during use, the regularly placed leeks on the conveyor belt 15 are conveyed into the conical cylinder 13 and finally fall into the weighing cylinder 5. The weighing plate 6 at the bottom of the weighing cylinder 5 can reflect the weight of the leeks currently entering the weighing cylinder 5; when the leeks meet the quality requirements, the conveyor belt 15 stops pouring the leeks into the weighing cylinder 5, and the rotating table 1 rotates to transfer the weighing cylinder 5 containing the leeks to the side of the fixed plate 18, and the push rod 17 shrinks and changes to make the hinged connecting rod 16 drive the fixed cylinder 4 to dump Then, the push rod 1 8 is extended and driven by the bent connecting plate 7 to make the weighing cylinder 5 leave the fixed cylinder 4, and the weighing cylinder 5 is inserted into the binding notch 23 on the surface of the fixed plate 18 along the direction of the limit groove 10. Since the leeks vertically placed in the weighing cylinder 5 are tilted and placed, the leeks are easy to be scattered to both sides and not easy to be tied. At this time, the gathering mechanism 12 drives the clamping plate 11 to gather the leeks scattered on both sides, and then the rubber band is hung on the surface of the hook 22. The rubber band is propped up under the action of each push rod 4 21, and the push rod 4 21 is used to push the rubber band to the push rod 4 21. When the rod three 20 drives the positioning plate 19 to move, the rubber band penetrates the leek to achieve the bundling of the leek. At the same time, another empty weighing cylinder 5 is located below the conveyor belt 15 under the action of the rotating table 1, and the empty weighing cylinder 5 can be used to put the leek. The rotating seat 2 is driven by the rotating table 1 to rotate, so that the leek in the fixed cylinder 4 continuously interacts with other equipment mechanisms. At the same time, the infrared transmitter 27 can send an infrared signal, and the rotating seat 2 is rotated according to whether the infrared receiver 28 receives the infrared signal to ensure that the fixed cylinder 4 can align with the corresponding mechanism, and then the above operations are repeated in sequence. The bundled leek can be moved to one side of the discharge plate 24 by the rotation of the rotating table 1, and the clamping plate 11 is released by the retracting mechanism 12. Under the continuous push of the push rod 1 8, the leek in the weighing cylinder 5 can be poured into the discharge plate 24. Under the action of the fixed cylinder 4, the fixed range of the bundled leek is guaranteed, the roots of the leek are aligned, the bundling effect is improved, and a series of operations such as quantitative weighing of leek, rubber band bundling and dumping of the bundled leek are automated.

[0038] In summary, the utility model arranges multiple weighing cylinders 5 on the surface of the rotating table 1. The weighing plate 6 can detect the weight of the leeks. At the same time, the roots of the leeks can be aligned under the restriction of the weighing cylinder 5, which makes it easier for the leeks to be bundled and not easily scattered. The rotating table 1 drives the weighing cylinder 5 to rotate, and the operations of weighing, bundling and discharging the leeks can be realized in turn, thereby ensuring the efficiency of bundling the leeks.
