Description

Technical Field

[0001] This utility model relates to the technical field of material feeding devices, specifically to a feeding device. Background Technology

[0002] Currently, the feeding methods for powdered (granular) materials in the large-scale infusion industry typically include manual feeding and vacuum conveying. Manual feeding is widely used due to its low cost and simple operation. However, when the material volume is large and the production duration is long, multiple manual feedings are required, which can easily lead to material mixing and low efficiency. While vacuum conveying can solve these problems, it suffers from high energy consumption, difficult maintenance, and stringent environmental requirements, resulting in significant maintenance costs should the machine malfunction. Currently, the country is implementing energy conservation and carbon reduction initiatives, promoting carbon peaking and carbon neutrality, and driving green and low-carbon development in the industry. To achieve green development and align with this national policy, while simultaneously addressing the problems with existing powdered (granular) material feeding methods in the large-scale infusion industry, there is an urgent need to select a new material conveying technology.

[0003] like Figure 1 The diagram illustrates a feeding method for large-volume parenteral solutions. After the raw material package is manually unpacked, it is transported to the vicinity of the first silo 102. The first material bag 101 is manually opened, and the material is slowly fed into the inlet of the first silo 102. Once all material has been fed, the first valve 103 is opened, and the first vacuum pump 104 is activated to pump the material into the first metering chamber 105. The airflow of the first vacuum pump 104 decreases as the weight of the first metering chamber 105 increases. Once the material in the first metering chamber 105 reaches the required weighing volume, the first vacuum pump 104 is turned off, the second valve 106 is opened, and the second vacuum pump 107 is activated to transfer all the material into the preparation tank, completing the feeding operation. This feeding method suffers from several technical problems, including high labor intensity, low manual efficiency, high equipment cost, large investment, large equipment footprint, high energy consumption, difficult equipment maintenance, high cost, and high risk.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0025] It should be noted that the embodiments and features involved in the embodiments of this utility model can be combined with each other without conflict. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] like Figures 2-5The feeding device shown includes a feeding station 203, an electric hoist 218, a second material bag 201, a robotic arm 214, a second hopper 207, and a second metering hopper 211.

[0027] The feeding station 203 is equipped with a transverse track 216, on which an electric hoist 218 is installed. The electric hoist 218 can move laterally along the transverse track 216. The electric hoist 218 is used to connect with the second material bag 201 and drive the second material bag 201 to move.

[0028] The electric hoist 218 is provided with a horizontal connecting rod 217 at the bottom, and hooks 204 are provided at both ends of the horizontal connecting rod 217; the hooks 204 are used to cooperate with the hanging rope 202 provided at the top of the second material bag 201 to hang the second material bag 201.

[0029] There are four such feeding stations on feeding station 203 Figure 3 and Figure 4 The robotic arm 214 shown is equipped with a blade 215; the blade 215 is used to cut open the bottom of the second material bag 201 to release the material; the bottom of the feeding station 203 is provided with a feeding outlet 205, the bottom of the feeding outlet 205 is connected to the second hopper 207, the bottom of the second hopper 207 is connected to the second metering hopper 211, and the bottom of the second metering hopper 211 is connected to a preparation tank (not shown in the figure) located below the second metering hopper 211. The preparation tank, electric hoist 218, and robotic arm 214 are existing technologies and will not be described in detail here.

[0030] In this embodiment, the second material bag 201 is hung on the horizontal connecting rod 217 by the hanging rope 202 and the hook 204. The electric hoist 218 is started, and the electric hoist 218 moves the second material bag 201 upward. After the second material bag 201 moves upward to a certain height, the electric hoist 218 moves to the left on the horizontal track 216 and drives the second material bag 201 to move. The second material bag 201 stops above the feeding outlet 205. The robot arm 214 controls the blade 215 to move upward and cut the bottom of the second material bag 201. Under the action of gravity, the material moves downward from the bottom of the second material bag 201 and falls into the feeding outlet 205. The material falling into the feeding outlet 205 falls into the second hopper 207 under the action of gravity. The material in the second hopper 207 falls into the second metering hopper 211 under the action of gravity. The material in the second metering hopper 211 falls into the preparation tank under the action of gravity. The feeding device provided in this embodiment moves the second material bag 201 by an electric hoist 218 and cuts open the bottom of the second material bag 201 by a robotic arm 214. Under the action of gravity, the material falls into the second hopper 207. The feeding of materials is completed by mechanical automation instead of manual labor, which can effectively reduce labor intensity and improve work efficiency. Figure 2In the middle, two electric hoists 218 are installed on the horizontal track 216. When one electric hoist 218 is attached to the second material bag 201, the second material bag 201 attached to the other electric hoist 218 is fed with material. Then, the two people move in the same direction, and the two electric hoists 218 alternately attach to the second material bag 201 and feed material.

[0031] The inlet of the second hopper 207 is connected to the outlet 205, and the outlet of the second hopper 207 is connected to the inlet of the second metering hopper 211; a third valve 206 is provided at the inlet of the second hopper 207, and a fourth valve 209 is provided at the outlet of the second hopper 207.

[0032] The inlet of the second metering chamber 211 is connected to the outlet of the second silo 207, and the outlet of the second metering chamber 211 is connected to the point of use equipment (preparation tank); the inlet of the second metering chamber 211 is equipped with a fifth valve 210, and the outlet of the second metering chamber 211 is equipped with a sixth valve 213.

[0033] In this embodiment, by setting the third valve 206 and the fourth valve 209, the entry and exit of materials in the second hopper 207 can be easily controlled; by setting the fifth valve 210 and the sixth valve 213, the entry and exit of materials in the second metering hopper 211 can be easily controlled.

[0034] The second hopper 207 is equipped with a first weighing module 208 on both sides, and the second metering hopper 211 is equipped with a second weighing module 212 on both sides.

[0035] In this embodiment, the first weighing module 208 is electrically connected to the third valve 206 and the fourth valve 209, and is used to control the opening ratio of the third valve 206 and the fourth valve 209; the second weighing module 212 is electrically connected to the fifth valve 210 and the sixth valve 213, and is used to control the opening ratio of the fifth valve 210 and the sixth valve 213.

[0036] The feeding outlet 205 is a funnel-shaped hopper with an upward opening (not shown in the figure).

[0037] In this embodiment, the feeding outlet 205 is a funnel-shaped hopper, which facilitates the receipt of materials flowing out from the bottom of the second material bag 201.

[0038] Working principle: The second material bag 201, after its outer packaging has been removed, is connected to the hanging rope 202, which is then attached to the hook 204. A controller connected to the electric hoist 218 controls the material bag to move upwards, then to the left above the feeding outlet 205. A controller connected to the robotic arm 214 controls the robotic arm 214 to operate, and the robotic arm 214 controls the blade 215 to cut open the bottom of the second material bag 201. The material inside the second material bag 201 falls into the feeding outlet 205 under gravity. The material falling into the feeding outlet 205 then falls into the second hopper 207 under gravity. The first weighing module 208 senses the weight of the material in the second hopper 207 and controls the opening of the third valve 206 and the fourth valve 209. As the weight of the material increases, the opening of the third valve 206 decreases until it closes completely. Then, the opening of the fourth valve 209 is increased to full open, and the material in the second hopper 207 falls into the second metering hopper 211 under gravity. The second weighing module 212 senses the weight of the material in the second metering hopper 211 and controls the opening of the fifth valve 210 and the sixth valve 213. As the weight of the material in the second metering hopper 211 increases, the opening of the fifth valve 210 gradually decreases until it is completely closed. When the material in the second metering hopper 211 reaches a specified weight, the fifth valve 210 closes, and the opening of the sixth valve 213 gradually increases until it is fully open, and the material in the second metering hopper 211 falls into the preparation tank under gravity. The material input and flow process mainly relies on gravity, which is energy-saving and environmentally friendly.
