[0041] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model belong to the scope of protection of the embodiments of the utility model.

[0042] Embodiment 1

[0043] See also Figure 1 , Figure 1 A schematic structural diagram of a production line for liquid medicine provided in Example 1 of the utility model, the production line includes a first medicine storage tank 1, multiple filling lines 2, multiple first liquid level gauges 3 and multiple first medicine outlet valves 4, the number of filling lines 2, first liquid level gauges 3 and first medicine outlet valves 4 is the same, as shown in the figure, the number is two, and the two filling lines are arranged in parallel.

[0044] The first medicine storage tank 1 can be made of suitable materials according to the medicine to be filled, and can be made of stainless steel or plastic. The first medicine storage tank 1 is provided with two medicine outlet pipes 5, and each medicine outlet pipe 5 is connected to the filling line 2 through the bottom of the first medicine storage tank 1. Each filling line 2 is provided with a hopper 6 for storing medicines, and each filling line 2 is used to fill the medicine to be filled in the first medicine storage tank 1 into a medicine bottle of corresponding capacity. The capacity filled by each filling line 2 is different, including specifications such as 500ml and 5L. A liquid level gauge 14 can be installed on the first medicine storage tank 1, and the volume of the remaining medicine in the first medicine storage tank 1 can be observed through the liquid level gauge 14.

[0045] Two first liquid level meters 3 are respectively installed in the hopper 6 of each filling line 2. The first liquid level meter 3 is used to measure the liquid level of the corresponding hopper 6. The first liquid level meter 3 outputs a first target signal when the liquid level is less than a first preset value. The first target signal is the signal output by the first liquid level meter 3 when the liquid level is less than the first preset value, which can be a level signal, such as a low level signal.

[0046] Two first medicine outlet valves 4 are respectively installed on each medicine outlet pipe 5, and each first medicine outlet valve 4 is connected to each first liquid level meter 3. The first medicine outlet valve 4 is converted from the initial closed state to the open state when receiving the first target signal, and is converted from the open state to the closed state when the first target signal disappears. The first medicine outlet valve 4 is a normally closed valve. When the liquid level in the hopper 6 is lower than the first preset value, it means that there is insufficient medicine when the filling line 2 is filling, and the first medicine outlet valve 4 is opened to transport the medicine in the first medicine storage tank 1 to the hopper 6.

[0047] Since different filling lines are filled with different quantities of products, the quantity of products filled by each filling line needs to be determined based on the production plan, which makes it cumbersome to count the production progress of each filling line. Furthermore, the production line also includes a flow meter 7 and a display terminal 8. The number of flow meters 7 is the same as the number of filling lines 2. Two flow meters 7 are respectively installed on two medicine outlet pipes 5 to measure the total filling amount of the corresponding filling line 2 in a single filling task. The display terminal 8 can be a liquid crystal screen device, and a plurality of signal input ports are provided on the display terminal 8, and each signal input port is connected to each flow meter 7.

[0048] The working process of the liquid medicine production line will be described in detail below. When it is necessary to produce medicines of different capacities, the medicines to be filled are prepared according to the production plan and placed in the first medicine storage tank 1. The first medicine outlet valve 4 and the first liquid level meter 3 are powered on. When the first liquid level meter 3 detects that there is no medicine in the hopper 6, it outputs the first target signal to the first medicine outlet valve 4. The first medicine outlet valve 4 is opened to transport the medicine in the first medicine storage tank 1 to the hopper 6. When the medicine reaches the first preset value, the first medicine outlet valve 4 is closed. Each filling line 2 is opened to fill medicine bottles of different capacities. The first liquid level meter 3 continues to detect the liquid level in the hopper 6 and controls the first medicine outlet valve 4 to keep the medicine in the silo full. The flow meter 7 on each medicine outlet pipe 5 measures the total filling volume of each filling line 2 and outputs it to the display terminal 8 for display. On-site personnel determine the production progress of products of different specifications based on the total filling volume of each filling line 2. After the filling line 2 completes the filling task of the corresponding capacity product, the first liquid level meter 3 and the first medicine outlet valve 4 of the filling line 2 are powered off, and the medicine is no longer transported to the hopper 6. The filling line 2 fills the remaining medicine in the hopper 6 and then stops.

[0049] Embodiment 2

[0050] In actual applications, due to the wide variety of veterinary drugs and water treatment agents, the formulas of various drugs are different. When producing each drug in small batches, it is necessary to complete the filling of one type of product before implementing drug preparation and filling, resulting in low filling production efficiency of liquid drugs.

[0051] In order to make the liquid medicine production line suitable for filling different types of products, the embodiment of the utility model provides another implementation scheme of the liquid medicine production line, please refer to Figure 2 , Figure 2 The schematic diagram of the structure of a production line of a liquid medicine provided in the second embodiment of the utility model. The production line includes a first medicine storage tank 1, multiple filling lines 2, multiple first liquid level gauges 3 and multiple first medicine outlet valves 4. In the second embodiment, there are two filling lines 2, two first liquid level gauges 3 and two first medicine outlet valves 4, which can realize the simultaneous filling of two products with different capacities.

[0052] Each filling line 2 includes a filling machine 21, a bottle cap feeder 22, a capping machine 23 and an aluminum foil capping machine 24. The filling machine 21 is connected to the medicine outlet pipe 5 of the first medicine storage tank 1, and the filling machine 21 is used to fill the medicine bottle with the corresponding liquid medicine. The conveyor belt inlet of the bottle cap feeder 22 is close to the conveyor belt outlet of the filling machine 21, and the bottle cap feeder 22 is used to configure the bottle caps for the medicine bottles that have been filled. The conveyor belt inlet of the capping machine 23 is close to the conveyor belt outlet of the bottle cap feeder 22, and the capping machine 23 is used to tighten the bottle caps for the medicine bottles that have been configured with the bottle caps. The conveyor belt inlet of the aluminum foil capping machine 24 is close to the conveyor belt outlet of the capping machine 23, and the aluminum foil capping machine 24 is used to perform aluminum foil sealing on the medicine bottles that have been tightened with the bottle caps, and transport them to the packaging process. A packaging platform 25 can be set at the end of the conveyor belt of the aluminum foil capping machine 24 to facilitate on-site personnel to package and organize the products that have been filled.

[0053] It can be understood that the filling machine 21, the bottle cap feeder 22, the capping machine 23 and the aluminum foil capping machine 24 are all transmitted through the output belt. In order to enable each filling line 2 to automatically control the production rhythm, the filling line 2 also includes a filling controller. The filling controller can be a PLC (Programmable Logic Controller) or an industrial computer. The filling controller is connected to the filling machine 21, the bottle cap feeder 22, the capping machine 23 and the aluminum foil capping machine 24, and can be connected to the control port of each device to collect the pulse signal of the encoder on the device and output the control signal of the motor running speed. The filling controller is used to interlock the equipment of the filling line 2. Interlocking control is a follow-up control implemented based on the running speed of each device. For example, when the filling beat of the filling machine 21 is reduced, the running efficiency of the conveyor belts of other equipment will be reduced accordingly.

[0054] Since the product capacities filled by different filling lines 2 are different, including 10L, 5L, 250ml, etc., filling machines 21 of different specifications can be configured accordingly. If the same caliber of the drug outlet pipe 5 is used, there is a problem of insufficient applicability. Based on this, the production line also includes a main pipeline 9, a branch pipe 10 and at least one reducer. The drug inlet of the main pipeline 9 is connected to the drug outlet at the bottom of the first drug storage tank 1; the drug inlet of the branch pipe 10 is connected to the drug outlet of the main pipeline 9, and the branch pipe 10 is provided with multiple drug outlets, each of which is connected to each drug outlet pipe 5. The reducer is installed between the branch pipe 10 and the drug outlet pipe 5. For filling machines 21 of different specifications, drug outlet pipes 5 of corresponding specifications can be selected. For example, a filling machine 21 of a large-sized product can be adapted to a large-caliber drug outlet pipe 5; conversely, a small-sized filling machine 21 is adapted to a small-caliber drug outlet pipe 5, and the branch pipe 10 and the drug outlet pipe 5 are connected through a reducer.

[0055] In order to make the production line suitable for filling different types of medicines, the production line also includes a second medicine storage tank 11, a second liquid level gauge 12 and a second medicine outlet valve 13. The second medicine storage tank 11 is provided with a medicine outlet pipe 5 connected to at least one filling line 2. The second medicine storage tank 11 is also equipped with a liquid level gauge 14. The caliber of the medicine outlet pipe 5 can be selected according to actual needs. Similarly, the second liquid level gauge 12 is installed in the hopper 6 of the filling line 2 connected to the second medicine storage tank 11. The second liquid level gauge 12 is used to measure the liquid level in the installed hopper 6. The second liquid level gauge 12 outputs a second target signal when the measured liquid level is less than the second preset value. The second medicine outlet valve 13 is installed on the medicine outlet pipe 5 connected to the second medicine storage tank 11. The second medicine outlet valve 13 is connected to the second liquid level gauge 12. The second medicine outlet valve 13 is converted from the initial closed state to the open state when receiving the second target signal, and is converted from the open state to the closed state when the second target signal disappears.

[0056] The production process of different types of medicines will be described below. When implementing large-scale multi-specification product filling, the medicine to be filled is prepared in the first medicine storage tank 1, and two filling lines 2 are opened to implement filling of different specifications. During the filling process, another type of medicine is prepared in the second medicine outlet tank. After the medicine in the first medicine storage tank 1 is filled, the first liquid level meter 3 and the first medicine outlet valve 4 are powered off, the filling machine 21 is cleaned with clean water, and the second liquid level meter 12 and the second medicine outlet valve 13 are powered on. The second liquid level meter 12 detects that the medicine in the hopper 6 is insufficient, outputs a second target signal, and controls the second medicine outlet valve 13 to open, so as to transport the medicine in the second medicine storage tank 11 to the corresponding hopper 6, and open the filling line 2 to implement filling until the medicine in the second medicine storage tank 11 is filled.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the utility model.

[0058] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
