Description

Technical Field

[0001] This utility model relates to an integrated stirring and weighing device for biopharmaceuticals, belonging to the field of biopharmaceutical research and development and production technology. Background Technology

[0002] High-precision weighing devices are often required in biopharmaceutical processes to ensure drug quality and safety. These devices typically feature high precision, stability, and automation, and require stirring during weighing to meet the stringent requirements of the pharmaceutical industry. However, existing biopharmaceutical weighing devices still have the following drawbacks: 1. When the mixer is running, the resulting vibration and load can affect the stability of the data displayed by the weighing module, leading to deviations in the weighing results; 2. When the mixer is operating, the generated electromagnetic field may interfere with the electronic components used in weighing, causing instability or increased error; 3. The mixer requires a large current supply, which may affect the power grid. Fluctuations in grid voltage and current can also affect weighing stability.

[0003] Therefore, it is necessary to propose an integrated stirring and weighing device for biopharmaceutical applications to overcome the above problems. Summary of the Invention

[0004] The purpose of this invention is to solve the above problems and provide an integrated stirring and weighing device for biopharmaceutical applications, thereby improving the overall performance of existing weighing devices for biopharmaceutical applications.

[0005] The technical solution of this utility model is: an integrated stirring and weighing device for biopharmaceutical applications, comprising a shell frame, a base at the bottom of the shell frame, a weighing module and a stirring motor inside the shell frame, and a top plate at the top of the shell frame. The stirring motor is located above the weighing module, and the stirring motor and the weighing module are integrally connected via a support mechanism. The support mechanism includes a horizontal support plate and a vertical support plate connected vertically, and the horizontal and vertical support plates are arranged in a "Γ" shape. The stirring motor is located at the lower part of the horizontal support plate, and its upper part is fixedly connected to the top plate. The weighing module is located at the upper part of the vertical support plate.

[0006] Furthermore, in the aforementioned integrated stirring and weighing device for biopharmaceutical applications, the transverse support plate includes a main plate and two side plates. Both the main plate and the two side plates are rectangular plate structures. The two side plates are symmetrically arranged at both ends of the main plate along the width direction of the main plate, and the two side plates and the main plate are distributed in a "ㄈ" shape.

[0007] Specifically, in the above-mentioned integrated stirring and weighing device for biopharmaceutical applications, the main board is fixed to the upper part of the vertical support plate, and the main board is perpendicularly connected to the vertical support plate. Reinforcing ribs are provided at the connection points between the two side plates and the vertical support plate.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings to make it easier to understand and master. The components involved, such as the base 2, weighing module 3, stirring motor 4, top plate 6, and pad 7, are all commonly used components that are generally recognized by those skilled in the art, and there are no special requirements for them in this application.

[0022] like Figures 1-6 As shown, this utility model provides an integrated stirring and weighing device for biopharmaceuticals, including an outer frame 1. The bottom of the outer frame 1 is provided with a base 2. At the four corners of the bottom of the base 2, there are pads 7. The pads 7 have a stable structure and can play a good supporting role to keep the weighing stable. The outer frame 1 is provided with a weighing module 3 and a stirring motor 4. The top of the outer frame 1 is provided with a top plate 6. The top plate 6 can form a container unit, which facilitates the temporary storage, handling and transportation of weighing raw materials for biopharmaceuticals.

[0023] According to the technical solution of this utility model: the stirring motor 4 is located on the upper part of the weighing module 3. The stirring motor 4 can also be equipped with devices such as voltage regulators and power filters to maintain a stable power supply current. The stirring motor 4 and the weighing module 3 (which is a weighing device) are integrally connected through a support mechanism 5. The support mechanism 5 includes a horizontal support plate 51 and a vertical support plate 52 that are vertically connected, and the horizontal support plate 51 and the vertical support plate 52 are distributed in a "Γ" shape. The stirring motor 4 is located on the lower part of the horizontal support plate 51, and the upper part of the stirring motor 4 is fixedly connected to the top plate 6.

The two side plates are symmetrically arranged at both ends of the main plate along the width direction of the main plate, and the two side plates and the main plate are distributed in a "U" shape.

[0025] Specifically, in the structure of the transverse support plate 51 of the aforementioned support mechanism 5, the main plate is fixed to the upper part of the vertical support plate 52, and the main plate is perpendicularly connected to the vertical support plate 52. Reinforcing ribs 53 are provided at the connection points between the two side plates and the vertical support plate 52. The reinforcing ribs 53 can improve the rigidity of the connection points between the two side plates and the vertical support plate 52, enabling them to better withstand working loads and vibrations, thereby improving working stability and accuracy; reducing the risk of deformation and breakage of the two side plates and the vertical support plate 52 during long-term use, and effectively extending the service life of the support mechanism 5.

[0026] Preferably, in the above structure: the outer shell frame 1 is provided with a right frame and a left frame that are assembled and joined in the horizontal direction. The two frames are fastened together along the longitudinal center line to form a cover. The interior of the cover forms a space for the integrated assembly of the weighing module 3, the stirring motor 4 and the support mechanism 5. The weighing module 3 and the stirring motor 4 can be protected by the outer shell frame 1.

[0027] Specifically, in the structure of the outer shell frame 1 described above, a fastener 8 is provided on one side of the cover portion. The fastener 8 is a component and a connecting pair. The outer shell frame 1 is reinforced by a combination of screws (or bolts, self-tapping screws) and flat washers (or spring washers, locking washers), thereby improving the installation strength of the outer shell frame 1.

[0028] Preferably, in the above structure: the stirring motor 4 is fixed to the center of the support mechanism 5 by a mounting plate 54, and the top of the stirring motor 4 is provided with a magnet 55 (the magnet 55 is one of neodymium iron boron magnet, samarium cobalt magnet or alnico magnet). The magnet 55 mainly functions in the mixer to help drive the stir bar of the mixer to rotate at high speed, thereby realizing the mixing and stirring function of raw materials for biopharmaceuticals.

[0029] In this utility model's technical solution, the key technology lies in the integrated and spaced arrangement of the stirring motor 4 and the weighing module 3 via the support mechanism 5.

Figures 4-6 The diagram shows the structural components of the support mechanism 5. For components such as the weighing module 3 and the stirring motor 4, those skilled in the art can perform conventional setups based on existing technology; this case does not have any special requirements regarding their model selection or combination.
