[0019] A filling device for preparing a mixture, comprising a homogenizing tank 1, a transition tank 4, a suspension conveyor 5, an injector 6, a conveying assembly 7 and a base 9. The homogenizing tank 1 is fixedly installed on the base 9. The conveying assembly 7 is fixedly mounted on one side of the base 9 away from the homogenizing tank 1. The transition tank 4 and the suspension conveyor 5 are evenly arranged on the base 9 between the homogenizing tank 1 and the conveying assembly 7. The transition tank 4 is arranged close to the homogenizing tank 1, and the suspension conveyor 5 is arranged close to the conveying assembly 7. A plurality of the injectors 6 are detachably and fixedly hoisted below the suspension conveyor 5, and a plurality of the injectors 6 are arranged at equal intervals. The medicine bottles 8 to be filled are placed on the conveying assembly 7, and the distance between adjacent medicine bottles 8 is the same as the distance between adjacent injectors 6. The operating linear speed of the suspension conveyor 5 is the same as the operating linear speed of the conveying assembly 7. The traditional Chinese medicine mixture stored in the homogenizing tank 1 is pumped into the transition tank 4. The injector 6 extracts the mixture from the transition tank 4. The suspension conveyor 5 operates to transport the injector 6 to move above the conveying assembly 7 and align with the medicine bottles 8, and the injector 6 fills the mixture into the medicine bottles 8.

[0020] The suspension conveyor 5 is integrally arranged in a closed form with the head and tail connected. The operation of the suspension conveyor 5 drives a plurality of injectors 6 to circulate and move between the transition tank 4 and the conveying assembly 7. The conveying assembly 7 is arranged in a closed form with the head and tail connected. While the conveying assembly 7 sends away the medicine bottles 8 that have completed filling, it brings the medicine bottles 8 that have not been filled.

[0021] The conveying assembly 7 includes a conveyor belt 71, a flexible conveyor belt 72, a support frame 75, a plurality of clamps 73 and a plurality of hanging supports 74. The conveyor belt 71 and the flexible conveyor belt 72 are both installed on the support frame 75. The rotation axis of the conveyor belt 71 is vertically arranged, that is, the working end face of the conveyor belt 71 is vertically erected. A plurality of hanging supports 74 are fixedly arranged at equal intervals on the working end face of the conveyor belt 71. A plurality of clamps 73 are movably inserted on the plurality of hanging supports 74. The medicine bottle 8 is movably inserted on the clamp 73. The supporting surface of the flexible conveyor belt 72 is horizontally arranged, and the linear speed of the flexible conveyor belt 72 is the same as that of the conveyor belt 71. The bottom surface of the medicine bottle 8 abuts against the flexible conveyor belt 72. The conveyor belt 71 transports the medicine bottle 8 through the clamp 73, and the flexible conveyor belt 72 provides stable support for the medicine bottle 8.

[0022] The injector 6 includes a tube body, a sliding plug 61 and an air pump 62. The air pump 62 is fixedly installed at the top inside the tube body. A material passing hole is formed at the bottom of the tube body. The sliding plug 61 is hermetically slidably installed inside the tube body and divides the inner cavity of the tube body into two independent chambers. The upper chamber is a driving chamber, and the lower chamber is a liquid extraction chamber. The air pump 62 operates by pumping air to discharge the air in the driving chamber to generate negative pressure, causing the sliding plug 61 to slide upward for extracting the mixture. The air pump 62 operates by inflating to fill the driving chamber with air, causing the sliding plug 61 to slide downward for extruding the mixture. The extraction of the mixture by the injector 6 is carried out in the transition tank 4, and the extrusion of the mixture is carried out at the medicine bottle 8. A ventilation hole 63 is provided at the top of the tube body to ensure the normal operation of the air pump 62. The ventilation hole 63 is tightly sealed by the air pump 62 without air leakage. By adjusting the air pumping time of the air pump 62 to control the air pumping volume, the lifting height of the sliding plug 61 inside the tube body can be adjusted, thereby adjusting the liquid extraction volume of the injector 6 per time.

[0023] The hanging conveyor 5 is installed on the base 9 through the second lifting seat 92. An installation plate is provided at the top of the second lifting seat 92. The guide rail 51 of the hanging conveyor 5 is fixedly installed on the lower surface of the installation plate. A plurality of sliding frames 52 are slidably installed on the guide rail 51. A hydraulic rod 53 is fixedly provided at the bottom surface of each sliding frame 52. The telescopic end of the hydraulic rod 53 points vertically downward. The injector 6 is fixedly provided at the end of the telescopic end of the hydraulic rod 53. Adjusting the lifting of the second lifting seat 92 can adjust the overall height of the hanging conveyor 5 to adapt to the filling of medicine bottles 8 of various specifications. Adjusting the length of the hydraulic rod 53 can independently adjust the height of a single injector 6, meeting the precise filling requirements and avoiding the collision between the injector 6 and the transition tank 4. The hanging conveyor 5 is a mature existing technology at the present stage and can be selected according to the specific application scale.

[0024] The transition tank 4 is installed on the base 9 through the first lifting seat 91 to cooperate with the working height of the hanging conveyor 5.

The feeding end of the pumping and conveying pump 41 is connected to the homogenizing tank 1 through a feeding pipe 42, and the discharging end of the pumping and conveying pump 41 is connected to the inside of the transition tank 4 through a feeding pipe 42. The pumping and conveying pump 41 operates to pump the mixture from the homogenizing tank 1 to the transition tank 4. The setting of the transition tank 4 prevents the direct influence on the filling work when there is a shortage of materials in the homogenizing tank 1. The mixture is stored in the transition tank 4, and the injector 6 extracts the mixture from the transition tank 4. The filling process in the homogenizing tank 1, etc., does not affect the filling work.

[0025] A liquid level monitoring component is provided in each of the transition tank 4 and the homogenization tank 1. The liquid level monitoring component monitors the liquid level heights in the homogenization tank 1 and the transition tank 4 in real time. When the liquid level in the homogenization tank 1 drops to a certain height, a warning is given. The warning means are a flashing light and a buzzer alarm. When the liquid level in the transition tank 4 rises to a certain height, the liquid level monitoring component sends a signal to the control circuit of the pumping pump 41 to control the pumping pump 41 to stop working, so as to prevent the mixture in the transition tank 4 from overflowing. The liquid level detection component is a publicly available technical means at the present stage and can be directly selected.

[0026] The homogenization tank 1 is fixedly arranged on one side of the base 9 away from the conveying component 7. A vertical plate 93 is arranged on the outer surface of the base 9 in contact with the homogenization tank 1. The upper end of the vertical plate 93 is hinged with a turning plate 3. The stirring rod 2 is rotatably installed on the lower end surface of the turning plate 3 facing the homogenization tank 1. A driving motor is fixedly embedded in the turning plate 3. The driving rod 31 of the driving motor passes out from the lower end surface of the turning plate 3. The top end of the stirring rod 2 is hinged to the end of the driving rod 31. The hinged axis of the driving rod 31 and the stirring rod 2 is parallel to the hinged axis of the turning plate 3 and the vertical plate 93. When the turning plate 3 needs to be turned up, the stirring rod 2 always hangs low, and the rotation axis of the stirring rod 2 will form an angle with the rotation axis of the driving rod 31. The mixture remaining on the stirring rod 2 will drip into the homogenization tank 1. At the same time, the stirring rod 2 and the homogenization tank 1 will not collide hard and cause damage. The turning plate 3 is driven by a stepping motor embedded in the vertical plate 93 to turn up or down. A support plate protrudes from the lower end surface of the turning plate 3 facing the homogenization tank 1. When the turning plate 3 is lowered to a horizontal position, the support plate will abut against the vertical plate 93 to maintain the stability of the horizontal position of the turning plate 3.

[0027] Working principle: Pour the mixture to be filled into the homogenization tank 1, lower the turning plate 3 to insert the two stirring rods 2 into the mixture, start the driving motor to rotate to make the stirring rods 2 rotate continuously to ensure the uniform texture of the mixture, and the pumping pump 41 operates to pump the mixture into the transition tank 4 for temporary storage.

[0028] A plurality of the clamps 73 are correspondingly hung on each hanging bracket 74, and the unfilled medicine bottles 8 are correspondingly inserted on the clamps 73. Start the suspension conveyor 5 to drive a plurality of filling devices 6 to circulate. Start the conveying component 7 to operate to drive a plurality of medicine bottles 8 to move in position. The suspension conveyor 5 and the conveying component 7 have the same linear speed. The filling device 6 and the medicine bottle 8 are aligned with each other and have the same moving speed. When the filling device 6 that has completed the extraction of the mixture at the transition tank 4 moves above the medicine bottle 8, adjust the hydraulic rod 53 to extend according to the specific height of the bottle mouth of the medicine bottle 8, so that the material passing hole at the bottom of the filling device 6 is close to the bottle mouth. Then control the air pump 62 to operate to lower the sliding plug 61 to pour the mixture in the filling device 6 into the medicine bottle 8. The suspension conveyor 5 and the conveying component 7 continue to operate to circulate the mixture filling work.

[0029] According to the different structural dimensions of the medicine bottles 8 to be filled, different-shaped clamps 73 can be designed according to the specific shapes of the specific medicine bottles 8 to ensure that the clamps 73 can stably hold the medicine bottles 8. According to the medicine bottles 8 of different sizes, the height of the second lifting seat 92 can be adaptively adjusted to adjust the height of the suspension conveyor 5, so as to realize the adaptive adjustment of the height of the injector 6. According to the specific height of the suspension conveyor 5, the height of the first lifting seat 91 is coordinately adjusted to make the height of the transition trough 4 adapt to the height of the injector 6. The material conveying pipe 42 is of a corrugated pipe structure and can adapt to the changing distance between the transition trough 4 and the homogenizing trough 1.
