[0019] As shown in the figure, a fixing frame 1, a silo 2, a distribution hopper 3, an upper vibration trough 4, and a weighing assembly are provided. The distribution hopper 3 can be used to divert the material in the silo 2 into the upper vibration trough 4, and then the upper vibration trough 4 is used to push the material forward through the vibration of the vibrator 14, so that the material falls into the weighing hopper 13 of the weighing assembly. The lower side of the weighing hopper 13 is provided with an automatic flip plate that can cover the lower side opening of the weighing hopper 13. When the weight of the material in the weighing hopper 13 reaches the set value, the vibrator 14 is turned off, and then the material is automatically flipped. When the rotating plate is opened, the material inside it can enter the lower vibration trough 5 to complete fine weighing. The lower vibration trough 5, the lower hopper 6, the material guide component, the conveying component and the packaging bottle 7 are set. The lower vibration trough 5 can be used to evenly convey the weighed material to the packaging bottle 7 through the material guide component to achieve the purpose of material weighing and packaging. The upper and lower vibration troughs can vibrate and spread the material to avoid material accumulation and transportation, which can well avoid the problem of material blockage and achieve the purpose of multi-layer vibration fine feeding.

[0020] The front side of the hopper 3 is provided with a partition 8, and the left and right sides of the partition 8 are respectively provided with waist-shaped grooves 9. The front end of the hopper 3 is fixedly connected to two left and right opposite screws 10 located in the waist-shaped grooves 9 on their corresponding sides, and a fixing knob 11 is threadedly connected to the screw 10.

[0021] As shown in the figure, the partition 8, the waist-shaped groove 9, the screw 10 and the fixed knob 11 are set. The fixed knob 11 and the screw 10 can be used to fix the partition 8 at the connection point of the distribution hopper 3 with the upper vibration groove 4, thereby controlling the discharge speed of the distribution hopper 3. At the same time, the waist-shaped groove 9 can be used to change the fixed position of the partition 8, and the size of the discharge port of the distribution hopper 3 can be adjusted according to the material of different volumes to ensure a stable discharge speed.

[0022] The weighing assembly includes a weighing device 12, the lower end of the weighing device 12 is fixedly connected to the fixed frame 1, and the front end of the weighing device 12 is fixedly connected to a weighing bucket 13. The front side wall of the weighing bucket 13 is an inclined surface with the upper front and the lower rear. The weighing bucket 13 is located between the upper vibration trough 4 and the lower vibration trough 5.

[0023] As shown in the figure, the weighing device 12 and the weighing bucket 13 can be used to weigh the material, thereby ensuring that the weight of the material falling into the packaging bottle 7 is uniform. The inclined surface can cushion the falling of the material and avoid damage to the material.

[0024] A vibrator 14 is provided at the lower end of the upper vibration trough 4 , the output end of the vibrator 14 is fixedly connected to the upper vibration trough 4 on its corresponding side, and the lower end of the vibrator 14 is fixedly connected to the fixing frame 1 .

[0025] As shown in the figure, a vibrator 14 is provided to drive the upper vibration trough 4 to vibrate and transport materials.

[0026] A second vibrator 15 is provided at the lower end of the lower vibration trough 5 . The output end of the second vibrator 15 is fixedly connected to the lower vibration trough 5 on its corresponding side. The lower end of the second vibrator 15 is fixedly connected to the fixing frame 1 .

[0027] As shown in the figure, a second vibrator 15 is provided to drive the lower vibration trough 5 to vibrate and transport materials.

[0028] The material diversion assembly includes a support plate 16, which is fixedly connected to the fixed frame 1, and the left and right sides of the support plate 16 are respectively fixedly connected to the cylinders 17. A lifting plate 18 is provided on the upper side of the support frame, and the left and right sides of the lifting plate 18 are respectively fixedly connected to the cylinders 17 on their corresponding sides. A plurality of variable diameter buckets 19 corresponding one to one to the lower hopper 6 are fixedly connected to the support plate 16, and the variable diameter bucket 19 is coaxial with the lower hopper 6.

[0029] As shown in the figure, the support plate 16, the cylinder 17, the lifting plate 18 and the variable diameter bucket 19 are set. The cylinder 17 can be used to drive the lifting plate 18 to rise and fall, and then the lower end of the variable diameter bucket 19 can be inserted into the packaging bottle 7 to ensure that the material can fall into the packaging bottle 7 normally without leakage. At the same time, it is ensured that after the unloading is completed, the lower side of the variable diameter bucket 19 can be lifted and pulled out of the packaging bottle 7, and then the conveying component can normally transport the packaging bottle 7 to the next process. The variable diameter bucket can serve the purpose of receiving the material.

[0030] The conveying assembly includes a bracket 20 , a conveying belt 21 is provided on the upper side of the bracket 20 , and baffles 22 are fixedly connected to the front and rear sides of the bracket 20 respectively.

[0031] As shown in the figure, a bracket 20, a conveyor belt 21 and a baffle 22 are provided to ensure that the packaging bottle 7 can be transported to its corresponding reducing bucket 19 for loading. At the same time, the baffle 22 can ensure that the packaging bottle 7 is in the center position of the conveyor belt 21, so as to prevent the reducing bucket 19 from being unable to insert into the packaging bottle 7 on its corresponding side.

[0032] When the utility model is in use, the position of the partition 8 is adjusted by using the fixed knob 11 so that the partition 8 is in a suitable position to ensure a stable material discharge speed;

[0033] The packaging bottle 7 is transported to its corresponding variable diameter bucket 19 by using the conveying assembly, and then the cylinder 17 is started to lower the height of the lifting plate 18 so that the lower side of the variable diameter bucket 19 is inserted into the packaging bottle 7. Then the vibrator 14 is started, and the vibrator 14 drives the upper vibration trough 4 to transport the material to the weighing hopper 13. The weigher 12 weighs the material in the weighing hopper 13. When the material reaches the specified weight, the vibrator 14 is turned off, and the vibrator 14 stops vibrating the upper vibration trough 4.

[0034] After weighing is completed, the vibrator 2 15 is started, and the vibrator 2 15 drives the lower vibration trough 5 to vibrate, and the automatic flip plate is opened, and the material falls from the weighing hopper 13 into the lower vibration trough 5. The lower vibration trough 5 drives the material to move evenly to the lower hopper 6 and then gradually enters the packaging bottle 7 through the diameter-reducing hopper 19 until all the weighed materials are packaged;

[0035] When the unloading speed is faster than or equal to the weighing speed, weighing and unloading can be performed simultaneously, that is, during the process of replacing the packaging bottle 7 after unloading, the weighed material enters the lower vibration tank 5 through the weighing bucket 13, thereby achieving the purpose of weighing and unloading at the same time;

[0036] After completion, the cylinder 17 is used to raise the lifting plate 18 to ensure that the diameter-changing bucket 19 is pulled away from the packaging bottle 7. Then the conveyor belt 21 sends the packaging bottle 7 away and transports the new packaging bottle 7 to the corresponding diameter-changing bucket 19.

[0037] In the present invention, the vibrator 14, the vibrator 2 15, the automatic turning plate and the cylinder 17 are all prior arts and will not be described in detail here.

Those skilled in the art may make various modifications, additions, or substitute similar methods to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
