Detailed ways
gravimetric blender
The following disclosure provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and are not intended to limit the invention. In addition, the present invention may repeat reference numerals and/or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and/or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and/or the use of other materials.

Please refer to Figures 1 to 5, the precision gravimetric blender provided by the embodiment of the present invention includes a base 1, on which multiple sets of blanking structures are provided, and the blanking structure includes a sub-barrel 2, a placing plate 3, and a supporting seat 4 , The sub-cylinder 2 is located on the placing plate 3, the placing plate 3 is set on the support base 4, and the support base 4 is installed on the base 1 through the load cell 5. The bottom of the sub-cylinder 2 and the placing plate 3 are correspondingly provided with a discharging port 6, a total charging cylinder 7 is arranged below the discharging port 6, and the total charging cylinder 7 has an inverted cone shape and is formed with a discharging port 8. The weighing sensor 5 is electrically connected with an electric control structure and a rotating blanking structure in the sub-barrel 2.

In the present invention, multiple sub-cylinders 2 are discharged simultaneously or separately, enter the main cylinder 7 and are mixed to form a mixed material. The load cell 5 detects the reduced weight of the blanking structure in real time, so as to precisely control the amount of blanking.

Generally speaking, in the operation of the present invention, a plurality of sub-barrels 2 are discharged at the same time, and a variety of powder materials enter the main barrel 7 for mixing, which is more efficient.

Specifically, during each blanking process of each group of blanking structures, the weighing sensor 5 corresponding to each blanking structure detects the overall weight reduction of the blanking structure in real time, and the electronic control structure and each group of weighing sensors 5 are independently electrically connected. Connection, real-time control of the number of blanks.

Further, the base 1 is provided with a through hole, the lower end of the main barrel 7 is penetrated with a through hole, and the discharge port 8 is located below the base 1. In this way, the material is discharged from the bottom of the base 1 to facilitate the placement of containers such as the receiving cup.

Further, multiple groups of blanking structures are arranged at intervals around the main barrel 7. In this way, different numbers of blanking structures, that is, different types of powder, can be set according to actual needs.

Further, the sub-cylinder 2 is independently detachable and replaceable. The placing plate 3 is provided with a bayonet 9. The protrusion 10 at the bottom of the sub-cylinder 2 and the bayonet 9 cooperate to fix the sub-cylinder 2, and the support base 4 is U-shaped. . In this way, the sub-cylinder 2 can be stably placed, and can be easily disassembled for cleaning or replacement. At the same time, the fixing structure in the present invention is simple and easy to make, which brings great convenience in operation and saves the time of medical staff.

Further, a cover plate 11 is provided on the main barrel 7, a stirring motor 12 is provided on the cover plate 11, and a stirring rod 13 is connected to the stirring motor 12, and the stirring rod 13 is located below the cover plate 11. In this way, after a variety of powder materials enter the main barrel 7, the stirring rod 13 rotates, and the auxiliary powder materials are mixed more evenly.

Of course, it is preferable that the stirring rod 13 continues to rotate, and the powder is evenly distributed throughout the main barrel 7 during the process of entering the main barrel 7.

Further, the stirring rod 13 includes a rod body, and a spiral stirring blade is surrounded on the rod body. The spiral stirring blade can not only ensure the stirring effect, make various powder materials uniformly mixed, but also prevent the powder materials from being contaminated on the stirring rod 13. Ensure the sanitary condition of the equipment.

Furthermore, two sets of grippers 14 are provided on the cover 11. In this way, it is convenient to lift the cover 11 along with the stirring motor 12 on the cover 11 and the stirring rod 13 under the cover 11.

Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and modifications can be made to these embodiments without departing from the principle and purpose of the present invention. The scope of the present invention is defined by the claims and their equivalents.[Gravimetric blender]
