Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a quantitative dispensing and packaging equipment for freeze-dried powder. Background Technology

[0002] Filling and dispensing equipment is a type of automated machinery specifically designed to precisely and quantitatively fill lyophilized powder materials, such as pharmaceuticals and biological agents, into vials. Its core function is to achieve standardized dispensing of lyophilized powder materials into vials by accurately controlling the filling volume, typically using either gravimetric or volumetric methods.

[0003] Chinese Patent Publication No. CN213416214U discloses a vial filling and capping machine for storing freeze-dried powder. This utility model is simple to operate, effectively tightens vial caps, has high capping efficiency and stability, greatly reduces rework caused by insufficient capping, and increases the production efficiency of enterprises. However, existing freeze-dried powder packaging equipment has the following drawbacks: when existing powder filling equipment quantitatively fills fine powders such as freeze-dried powder, the actual filling amount is prone to deviation from the set value due to the light texture, easy agglomeration or uneven distribution of freeze-dried powder. When the amount added exceeds the set value, the existing equipment lacks an effective real-time correction mechanism. Excess material is usually directly discarded or pollutes the production environment, which not only wastes materials but may also increase cleaning costs. Utility Model Content

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a quantitative dispensing and packaging equipment for freeze-dried powder. It solves the problem that existing powder filling equipment often results in deviations between the actual filling amount and the set value when quantitatively filling fine powders such as freeze-dried powder. This is because freeze-dried powder is lightweight, prone to agglomeration or uneven distribution. Furthermore, when the amount dispensed exceeds the set value, existing equipment lacks an effective real-time correction mechanism, and excess material is usually directly discarded or used to pollute the production environment, which not only wastes materials but may also increase cleaning costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A freeze-dried powder quantitative dispensing and packaging device includes a central control cabinet. The central control cabinet is equipped with a feeding mechanism for convenient quantitative packaging. The feeding mechanism includes a motor, a feeding hopper, and a conveyor tray. The motor is fixedly installed at the side end of the central control cabinet. Two electronic weighing scoops are provided at the side end of the motor. The feeding hopper is fixedly installed at the upper end of the central control cabinet. A rotating shaft is fixedly installed at the output end of the motor. The two electronic weighing scoops are respectively fixedly installed at the upper and lower ends of the rotating shaft. A material removal valve is fixedly installed at the side end of each of the two electronic weighing scoops. An L-shaped fixing rod is fixedly installed at the side end of the motor. A recycling box is fixedly installed at the side end of the L-shaped fixing rod. An installation component is fixedly installed at the output end of the motor, and a filling hopper is fixedly installed on the installation component.

[0006] Preferably, a discharge pipe is fixedly installed at the lower end of the feeding hopper.

[0007] Preferably, the conveyor tray is located at the side end of the central control cabinet, and both sides of the conveyor tray are equipped with conveyor belts.

[0008] Compared with the prior art, the present invention has the following beneficial effects. I. This device is equipped with an electronic weighing scoop and a filling hopper. The electronic weighing scoop monitors the weight of the freeze-dried powder in real time, and the material removal valve recovers excess material to dynamically adjust the amount of material. This reduces the measurement deviation caused by factors such as uneven texture of the freeze-dried powder and equipment delay, making the actual amount dispensed closer to the set value. The weighing and recovery response parameters can be flexibly adjusted according to the characteristics of the freeze-dried powder, such as its flowability and agglomeration, to adapt to the filling needs of different types of freeze-dried powder.

[0009] Second, this device is equipped with a recycling bin. When the amount of material added exceeds the set value, the discharge valve is opened to recycle and reuse the excess material, avoiding the problem of direct waste of excess material in traditional equipment. It is especially suitable for filling high-value freeze-dried powder and improves the material utilization rate. Attached Figure Description

[0013] This application provides a quantitative dispensing and packaging device for freeze-dried powder, which effectively solves the problem that existing powder filling equipment often encounters discrepancies between the actual filling amount and the set value when quantitatively filling fine powders such as freeze-dried powder. This is because freeze-dried powder is lightweight, prone to agglomeration, or unevenly distributed, leading to deviations. Furthermore, existing equipment lacks an effective real-time correction mechanism when the amount dispensed exceeds the set value, resulting in the excess material being directly discarded or polluting the production environment, causing material waste and potentially increasing cleaning costs. This device, through the combination of an electronic weighing scoop 22 and a filling hopper 32, monitors the weight of the freeze-dried powder in real time using the electronic weighing scoop 22, and dynamically adjusts the amount of excess material using a material removal valve 23. This reduces measurement deviations caused by uneven freeze-dried powder texture and equipment delays, making the actual dispensing amount closer to the set value. Example

[0014] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that existing powder filling equipment, when quantitatively filling fine powders such as freeze-dried powder, is prone to deviations between the actual filling amount and the set value due to the light texture, easy agglomeration, or uneven distribution of freeze-dried powder. Furthermore, when the amount dispensed exceeds the set value, existing equipment lacks an effective real-time correction mechanism, and excess material is usually directly discarded or pollutes the production environment, causing not only material waste but also potentially increasing cleaning costs. The overall approach is as follows: A freeze-dried powder quantitative dispensing and packaging equipment, including a central control cabinet 1, a central control... The cabinet 1 is equipped with a feeding mechanism for easy quantitative packaging. The feeding mechanism includes a motor 2, a motor 3, a feeding hopper 4, and a conveyor tray 5. When the user is dispensing and packaging freeze-dried powder in vials, the vials are arranged on the conveyor belt 51 and transported to the conveyor tray 5 by the conveying equipment. When the conveyor tray 5 rotates, it will move the vials one by one to the bottom of the filling hopper 32. When feeding the freeze-dried powder, it is discharged through the discharge pipe 41 on the feeding hopper 4. The freeze-dried powder is put into the electronic weighing scoop 22, which can weigh the added freeze-dried powder. Motor 2 is fixedly installed on the side end of central control cabinet 1. Two electronic weighing scoops 22 are provided on the side end of motor 2. Motor 3 is fixedly installed on the side end of central control cabinet 1. Feeding hopper 4 is fixedly installed on the upper end of central control cabinet 1. A rotating shaft 21 is fixedly installed on the output end of motor 2. The two electronic weighing scoops 22 are respectively fixedly installed on the upper and lower ends of rotating shaft 21. Discharge valves 23 are fixedly installed on the side ends of both electronic weighing scoops 22. When the filling volume is reached, the discharge valve of feeding hopper 4 can be closed through the central control system in central control cabinet 1. Motor 2 will be started to drive rotating shaft 21 to rotate. Rotating shaft 21 drives two electronic weighing scoops 22 to rotate. The upper electronic weighing scoop 22 will put the freeze-dried powder inside into filling hopper 32. An L-shaped fixing rod 25 is fixedly installed on the side end of motor 2, and a recycling bin 24 is fixedly installed on the side end of the L-shaped fixing rod 25. An installation component 31 is fixedly installed at the output end of motor 3, and a filling hopper 32 is fixedly installed on the installation component 31. A discharge pipe 41 is fixedly installed at the lower end of feeding hopper 4. Conveyor plate 5 is located at the side end of central control cabinet 1. Conveyor belts 51 are provided at both ends of conveyor plate 5. Central control cabinet 1 can simultaneously drive motor 3 to start. The vibration of motor 3 will cause the installation component 31 and filling hopper 32 to vibrate. The vibration of filling hopper 32 will cause the filling hopper to vibrate. The freeze-dried powder inside 32 is filled into vials on the conveyor tray 5, and this feeding is repeated. During feeding, due to uneven distribution of the freeze-dried powder texture, equipment delay, etc., there may be an error in the amount fed into the electronic weighing spoon 22. When the error is too large, the electronic weighing spoon 22 will activate the weighing sensor to open the discharge valve 23. After the discharge valve 23 is opened, the excess freeze-dried powder will be collected in the recycling box 24 through the discharge valve 23. The excess freeze-dried powder is removed and recycled. After the electronic weighing spoon 22 weighs the freeze-dried powder to the appropriate amount, it will close the discharge valve 23.

[0015] To address the problems existing in the prior art, this utility model provides a quantitative dispensing and packaging equipment for freeze-dried powder. This device uses an electronic weighing spoon 22 and a filling hopper 32 in combination. The electronic weighing spoon 22 monitors the weight of the freeze-dried powder in real time, and the material removal valve 23 is used to dynamically adjust the excess material. This can reduce the measurement deviation caused by factors such as uneven texture of freeze-dried powder and equipment delay, and make the actual amount dispensed closer to the set value.

[0016] Working principle: When users repackage freeze-dried powder into vials, they arrange the vials on conveyor belt 51 and transport them to conveyor tray 5. As conveyor tray 5 rotates, it moves the vials one by one to below the filling hopper 32. During the feeding of freeze-dried powder, it is discharged through the discharge pipe 41 on the feeding hopper 4. The freeze-dried powder is fed into the electronic weighing scoop 22, which weighs the added freeze-dried powder. When the filling volume is reached, the discharge valve of the feeding hopper 4 is closed via the central control system in the central control cabinet 1. The motor 2 is then started, driving the rotating shaft 21 to rotate. The rotation of the rotating shaft 21 drives the two electronic weighing scoops 22 to rotate. The electronic weighing scoop 22 feeds the freeze-dried powder inside into the filling hopper 32. Simultaneously, the central control cabinet 1 can start the motor 3. The vibration of the motor 3 causes the mounting component 31 and the filling hopper 32 to vibrate. This vibration causes the freeze-dried powder inside the filling hopper 32 to be filled into vials on the conveyor tray 5. This feeding process is repeated. During feeding, due to uneven distribution of the freeze-dried powder or equipment delays, there may be errors in the amount fed into the electronic weighing scoop 22. If the error is too large, the electronic weighing scoop 22 will activate the weighing sensor, causing the discharge valve 23 to open. After the discharge valve 23 opens, the excess freeze-dried powder will be collected in the recycling bin 24. The freeze-dried powder is discarded and recycled. After the electronic weighing scoop 22 weighs the freeze-dried powder to the appropriate amount, the discharge valve 23 is closed, and the above steps are repeated for dispensing and packaging. Existing powder filling equipment, when quantitatively filling fine powders such as freeze-dried powder, is prone to deviations from the set value due to the light texture, easy agglomeration, or uneven distribution of the freeze-dried powder. When the dispensing amount exceeds the set value, the existing equipment lacks an effective real-time correction mechanism. Excess material is usually directly discarded or pollutes the production environment, which not only wastes materials but may also increase cleaning costs. This device uses an electronic weighing scoop 22 and a filling hopper 32 in conjunction to weigh the freeze-dried powder to the appropriate amount. 2. Real-time monitoring of the weight of freeze-dried powder, combined with the recovery function of the discharge valve 23, dynamically adjusts excess material, reducing measurement deviations caused by uneven freeze-dried powder texture and equipment delays, making the actual amount dispensed closer to the set value. The weighing and recovery response parameters can be flexibly adjusted according to the characteristics of freeze-dried powder, such as flowability and agglomeration, to adapt to the filling needs of different types of freeze-dried powder. In addition, this device is equipped with a recovery box 24. When the amount dispensed exceeds the set value, the discharge valve 23 is opened to realize the recovery and reuse of excess material, avoiding the problem of direct waste of excess material in traditional equipment. It is especially suitable for filling scenarios of high-value freeze-dried powder, improving material utilization.

[0017] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
