[0032] The working principle of the present invention is: when in use, first, pour the spherical material (such as hazelnuts) into the feed bin 7, then start the stepper motor 10, the spiral feeding rod 9 rotates, and the material entering the feeding trough 8 from the feed bin 7 is pushed into the first vertical slot 11 by the spiral feeding rod 9, and then enters the trapezoidal slot 15 of the lower circular plate 13 along the first vertical slot 11. The first weighing sensor 16 in the trapezoidal slot 15 weighs the fallen material. If the weight of the material meets the standard, the feeding is stopped, and the circular plate 13 is rotated to align the next empty trapezoidal slot 15 with the first vertical slot 11. When the material does not meet the standard, if the insufficient weight is large, it is okay, just continue to feed through the spiral feeding rod 9, but if the insufficient weight is small, continuing to load will not only result in excessive feeding, but also affect the subsequent covering of the lid. At this time, it is necessary to use the subsequent single product weighing and discharging assembly to make a micro-feed.

[0033] The containers 5 are placed on the conveyor belt 4 in sequence, and the conveyor belt 4 transports the containers 5 to the front. When the containers 5 reach the positioning mechanism, the second position sensor 20 on the positioning mechanism senses the position of the container 5 and operates the first cylinder 21. The two output shafts of the first cylinders 21 extend synchronously to move the two clamping plates 18 closer to each other, thereby clamping and positioning the containers 5. At this time, the containers 5 are just below the discharge port 17, and the materials that meet the standards and the materials that are less than the standard in the rotary weighing and discharging assembly are transported to the discharge port 17 by the rotating circular plate 13, and fall from the discharge port 17 into the corresponding containers 5 below. After receiving the material, the container 5 continues to follow the conveyor belt 4 to the bottom of the single product weighing and discharging component. The single product weighing and discharging component only replenishes the material in the container 5 that is less than the weight, and does not replenish those that meet the standard. In the process of the container 5 moving to the bottom of the single product weighing and discharging component, the single product weighing and discharging component picks the single product material of the appropriate weight that needs to be replenished in the container 5. The specific selection process is: the second cylinder 33 runs to retract the output shaft, driving the switch plate 34 to retract the telescopic slot 32, and the single product slot 23 is exposed. The opening of the single product slot 23 is small and can only allow one single material item to enter at a time. When a single material item enters the single product slot 23 and falls into the slot 29 of the right-angle plate 28, the second weighing sensor 30 weighs the single material item. At the same time, the second cylinder 33 runs again to extend the output shaft so that the switch plate 34 extends to block the single product slot 23.

[0034] When the second weighing sensor 30 weighs the single item of material, if the single item of material meets the replenishment weight, the transmission motor 31 runs to drive the right-angle plate 28 to rotate ninety degrees, and the single item of material is introduced into the first chute 24 and enters the second vertical slot 25. At the same time, the specific position of the container 5 in the through slot 2 is monitored in real time by the first position sensor 59, so that the material to be replenished is introduced into the corresponding second chute 26 through the material stopping and guiding mechanism, and falls from the second chute 26 to the corresponding third vertical slot 27 below, and finally falls from the third vertical slot 27 into the passing container 5. If the container 5 has not reached the bottom of the corresponding third vertical slot 27, the single item of material is first stopped for a period of time by the material stopping and guiding mechanism, and then the single item of material is released for delivery when the container 5 passes. It should be noted that if after the first single item of material that meets the refill weight is selected, another container 5 that needs refilling appears, at this time, the first single item of material that meets the refill weight is retained at the top of the second chute 26 at the bottom through the material stopping and guiding mechanism, and the next single item of material that meets the refill weight is reselected to be delivered to the next container 5 that needs refilling, and so on. When multiple containers 5 that need refilling appear, the container 5 that first arrives at the single item weighing and discharging component is refilled from the third vertical slot 27 on the far right. The specific working principle of the material stopping and guiding mechanism is as follows: when the third cylinder 38 extends the output shaft, the steel wire rope 39 is released, and the obtuse plate 35 deflects to the right under the gravity of the weight block 36 to block the second vertical slot 25, and the material item falls on the obtuse plate 35. At this time, the material item is in the material stopping stage, and in the feeding stage, the third cylinder 38 only needs to retract the steel wire rope 39 to drive the obtuse plate 35 to flip back to the initial position, and the material on the obtuse plate 35 will be guided into the adjacent second chute 26. It should be noted that when multiple material items enter the second vertical slot 25, multiple material stopping and guiding mechanisms stop the material in sequence from bottom to top. In addition, if the second weighing sensor 30 weighs the material item and the material item is waste material that does not meet the refill weight or is too light and hollow, when the material item is introduced from the first chute 24 into the second vertical slot 25, all the obtuse plates 35 in the second vertical slot 25 maintain their initial positions, and the material item falls to the bottom of the second vertical slot 25 and flows out from the waste outlet 40. In addition, if waste material is mixed among the multiple material items entering the second vertical slot 25, the material item below the waste material will be guided out from the waste outlet 40 after the refill is completed.

[0035] When the container 5 reaches the bottom of the top cover assembly assembly through the single product weighing and discharging assembly, the top cover assembly assembly seals the container 5. The specific sealing process is as follows: the linear motor moves along the linear guide rail 41, driving the moving plate 42 to move to the rear of the cover stacking mechanism, and then the lifting plate 43 moves downward to drive the negative pressure suction head 45 to descend and extend into the cover stacking mechanism. The negative pressure suction head 45 sucks the topmost cover 50 from the covers 50 stacked in the cover stacking mechanism, and then transfers the cover 50 to the top of the cover delivery port. After the container 5 reaches the bottom of the cover delivery port, the conveyor belt 4 stops, and the lifting plate 43 descends so that the cover 50 passes through the cover delivery port and covers the top of the container 5. Then, the rotating motor 44 runs to drive the cover 50 to rotate on the top of the container 5. Finally, the negative pressure suction head 45 disconnects the negative pressure source to release the cover 50 and restores the initial position. After the container 5 is assembled with the cover 50, it is sent out of the machine body 1 through the conveyor belt 4.

[0036] When the cover bodies 50 of the cover body stacking mechanism are insufficient and need to be replenished, it is only necessary to pull the square bottom plate 46 of the cover body stacking mechanism outward. During the process, the slide rail 48 and the slide seat 47 are relatively displaced. After the square bottom plate 46 passes through the upper cover opening 61 to reach the outside of the machine body 1, the staff stacks the cover bodies 50 on the square bottom plate 46 in sequence, and the cover bodies 50 are restricted by the positioning vertical plates 53 around them to maintain an upward and downward alignment. It should be noted that when the size of the cover bodies 50 changes, the adjustment members provided can be used to make targeted adjustments according to the size of the cover bodies 50 to ensure that the stacked cover bodies 50 will not deviate up and down. The specific adjustment process is: the staff turns the handle 58 from the bottom of the square bottom plate 46 to drive the toothed disc 56 to rotate. Since the transmission gear 57 is meshed with the toothed disc 56, the transmission screw 52 rotates accordingly, and the slide plate 54 moves slowly along the transmission screw 52 in the slide groove 51, thereby making the four positioning vertical plates 53 synchronously approach or move away from the center.
