The feeding section 11 is horizontally arranged or tilted downward from front to back, and the feeding section 11 is convenient for receiving materials; the lifting section 12 is tilted upward from front to back, and the discharging section 13 is horizontally arranged. A plurality of partition plates 14 are evenly spaced on the conveyor belt of the first conveyor 1. When the feeding section 11 is tilted downward from front to back, its tilt angle is smaller than that of the lifting section 12. The partition plates 14 on the first conveyor 1 are conducive to lifting and conveying, and prevent the rock sugar from flowing back and falling during lifting.

[0025] like Figure 1 As shown, the vibrating screen mechanism 7 is used to screen the rock sugar and provide the rock sugar to the first conveyor 1, and the feeding port 7 of the vibrating screen mechanism 7 is arranged above the feeding section 11. The vibrating screen mechanism 7 can adopt an existing mechanism.

[0026] like Figure 3 , Figure 4 As shown, the discharge port of the storage bin 2 is connected with the feed port of the metering bin 3, and the lower part of the storage bin 2 is divided into an upper chamber 23 and a lower collecting tank 22 by a screening net 21. The lower collecting tank 22 is used to collect small-grained rock sugar separated by the screening net 21. A first discharge valve 24 is provided on the discharge port of the upper chamber 23, and a second discharge valve 25 is provided on the discharge port of the lower collecting tank 22. A vibration motor 26 is installed on the storage bin 2. Among them, the first discharge valve 24 includes a first valve baffle plate 241 and a first cylinder 242 installed outside the storage bin 2 for controlling the opening and closing of the first valve baffle plate 241.

The second valve material baffle plate 251 is rotatably connected to the storage bin 2, and the two ends of the rotating shaft of the second valve material baffle plate 251 are connected with connecting rods 253. The other end of the connecting rod 253 is hinged to the telescopic end of the second cylinder 252, and the other end of the second cylinder 252 is hinged to the storage bin 2.

[0027] like Figure 5 , Figure 6As shown, a discharge hopper 4 is provided at the lower part of the metering bin 3, and a bag clamping mechanism 5 is installed on the discharge hopper 4. The bag clamping mechanism includes bag clamping plates 51 installed on both sides of the outside of the discharge hopper 4 and a third cylinder 52 for controlling the action of the bag clamping plate 51.

[0028] like Figure 1 As shown, the second conveyor 6 is arranged below the discharge hopper 4, and the second conveyor 6 is used to convey the bagged rock sugar, and the guardrails 61 are provided on both sides of the second conveyor 6. The guardrails 61 play a role in limiting the tipping of the packaging bag, so as to facilitate the conveyance of the bagged rock sugar to the next bag sewing station.

[0029] The method of using the device is:

[0030] 1. The operator puts the packaging bag into the discharge port of the discharge hopper 4, and the third cylinder 52 extends to control the bag clamping plate 51 to move and clamp the packaging bag;

[0031] 2. After being screened by the vibrating screen mechanism 7, the crystal sugar that meets the specifications falls into the feeding section 11 of the first conveyor 1, and is lifted and transported upward to the storage bin 2 by the first conveyor 1. The large crystal sugar falls into the upper chamber 23 of the storage bin 2, and the small crystal sugar passes through the mesh of the screening net 21 and falls into the lower collecting tank 22 for collection;

[0032] 3. Set the rough and fine weights of the metering bin 3, firstly perform rough weighing through the large rock sugar in the upper chamber 23, and then perform fine weighing through the lower rock sugar in the lower collecting tank 22; specifically, the first cylinder 242 on the storage bin 2 contracts, and the first valve baffle plate 241 of the upper chamber 23 is controlled to open, so that the large rock sugar in the upper chamber 23 of the storage bin 2 falls into the metering bin 3 according to the set measurement, and falls into the packaging bag through the discharge port on the discharge hopper 4 of the metering bin 3. After the rough weighing requirement is met, the first cylinder 242 extends and closes. The first valve baffle plate 241 of the upper chamber 23, and then the second cylinder 252 extends, driving the connecting rod 253 to rotate clockwise, so that the second valve baffle plate 251 is rotated and opened, and at the same time the vibration motor 26 vibrates, so that the small rock sugar in the lower collecting tank 22 of the storage bin 2 falls into the metering bin 3 under the action of vibration, and falls into the packaging bag through the discharge port on the discharge hopper 4 of the metering bin 3, realizing accurate weighing, and then the second cylinder 252 contracts, driving the connecting rod 253 to rotate counterclockwise, and closing the second valve baffle plate 251;

[0033] 4. After the precise weighing is completed, the third air cylinder 52 contracts to control the bag clamping plate 51 to open, so that the measured and packaged packaging bags fall onto the second conveyor 6 and are transported to the next process via the second conveyor 6.

[0034] The utility model can be applied to the packaging of various particles such as large, medium, small and powdered ice. Since the upper chamber 23 and the lower collecting trough 22 are separated by the screening net 21 in the storage bin 2, the lower collecting trough 22 is used to collect small particles of rock sugar. When measuring, the large rock sugar in the upper chamber 23 is firstly roughly weighed, and then the small rock sugar collected in the lower collecting trough 22 is finely weighed, so that the weighing accuracy of the large rock sugar is well controlled.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
