However, the existing battery raw material stirring device in the prior art cannot weigh the stirred battery raw materials after stirring. If the next process requires a certain amount of battery raw materials, it is necessary to reweigh after discharging, resulting in complex and inconvenient operation procedures. Summary of the Utility Model

[0004] Aiming at the above deficiencies, the purpose of the present utility model is to provide a raw material stirring device and method capable of weighing, which solves the problem that the stirring device in the prior art cannot weigh the stirred battery raw materials.

[0037] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them.

[0038] Please refer to Figure 1 and Figure 2 , a weighable raw material stirring device, comprising a frame 1 and a stirring barrel 2 installed on the frame 1. The frame 1 is composed of 4 vertical rods 1a, and the upper and lower ends of the vertical rods 1a are respectively connected to each other to ensure stability. An installation platform 1b is provided at the lower end of the frame 1, and the barrel body 2a of the stirring barrel 2 is fixedly installed on the installation platform 1b at the lower end of the frame 1. The barrel cover 2b of the stirring barrel 2 is movably arranged up and down on the frame 1, and a plurality of groups of stirring mechanisms 3 are fixedly installed on the barrel cover 2b. A weighing mechanism 4 for weighing the raw materials in the stirring barrel 2 is provided below the installation platform 1b of the frame 1, and the weighing mechanism 4 is electrically connected to a controller 5 arranged on one side and displays the weighing data. The electrical connection between the controller 5 and the weighing mechanism 4 belongs to the prior art and will not be elaborated here one by one. In this application, by arranging the weighing mechanism 4 below the stirring barrel 2, the battery raw materials can be quantitatively stirred, or the stirred battery raw materials can be weighed in real time. When sent to the next process, there is no need to weigh again, which improves the convenience and versatility of the stirring device.

[0039] Furthermore, please continue to refer to Figure 2 and Figure 3, the weighing mechanism 4 includes a cross mounting frame 4a and gravity sensors 4b respectively disposed at the vertices of the cross mounting frame 4a. Below the frame 1, there is a mounting beam 1d. The cross mounting frame 4a is fixedly installed on the mounting beam 1d of the frame 1. The gravity sensors 4b are in contact with the mounting platform 1b to weigh the raw materials in the barrel body 2a. The gravity sensors 4b are electrically connected to the controller 5 and can transmit the weighing signals to the controller 5 for display. In this embodiment, the barrel body 2a is fixedly connected to the mounting platform 1b through a plurality of support columns 2c, and the lower ends of the support columns 2c are arranged corresponding to the positions of the gravity sensors 4b. There is a certain distance between the lower part of the mixing barrel 2 and the mounting platform 1b to facilitate the connection of the discharge pipe and the arrangement of other pipes.

[0040] Please continue to refer to Figure 1 , the barrel cover 2b is installed on the frame 1 through a sliding mechanism 6. The sliding mechanism 6 includes a connecting rod 6a. At both ends of the connecting rod 6a, there are limit members 6b. The limit members 6b are provided with sliding grooves, and the sliding grooves are slidably installed on the vertical rods 1a of the frame 1. When the sliding mechanism 6 moves up and down, it slides up and down along the vertical rods 1a as guides. And the middle part of the connecting rod 6a is fixedly connected to the barrel cover 2b. The connecting rod 6a is fixedly connected to a driving cylinder 7 arranged at the lower end and drives the barrel cover 2b to move up and down through the driving cylinder 7. In this embodiment, there are two groups of the sliding mechanism 6 and the driving cylinder 7, which are symmetrically arranged on both sides of the barrel cover 2b respectively, so as to ensure that the barrel cover 2b is more evenly stressed when moving up and down, and thus the stability of moving up and down can be improved.

[0041] At the lower end of the limit member 6b, there is a limit cylinder 8. A limit pin is connected to the limit cylinder 8. Corresponding limit holes 1c are provided on the vertical rod 1a. After the sliding mechanism 6 moves upward, the limit pin is inserted into the limit hole 1c for fixing and limiting. And in this embodiment, limit cylinders 8 are provided at the lower ends of the limit members 6b, with a total of 4. After the barrel cover 2b moves upward and stops, the barrel cover 2b is fixed on the frame 1 through the limit member 6b, thus ensuring the safety during cleaning.

[0042] In view of the fact that when a single stirring mechanism is used to stir the battery raw materials in the barrel in the prior art, due to the structural design limitations of the stirring mechanism, the stirring efficiency of the battery raw materials is low and the uniformity is poor. Therefore, the structural design of the stirring mechanism 3 in this application is as follows:

[0043] Please continue to refer to Figure 1 , Figure 4 and Figure 5, the stirring mechanism 3 is arranged in 3 groups, including a first stirring mechanism 3a, a second stirring mechanism 3b and a third stirring mechanism 3c arranged side by side, and the 3 groups of stirring mechanisms are fixedly connected by a connecting beam 3d. A crawler 3e is provided on the connecting beam 3d, and the other end of the crawler 3e is connected to the frame 1. It can ensure the stability of multiple stirring mechanisms 3 during stirring and reduce the vibration generated during the stirring process. And in this embodiment, the first stirring mechanism 3a includes a first stirring motor 31a fixedly installed on the bucket cover 2b. The output end of the first stirring motor 31a is drivingly connected with a first stirring rod 32a, and multiple groups of first stirring paddles 33a are arranged at intervals on the first stirring rod 32a. The first stirring mechanism 3a and the second stirring mechanism 3b have the same structure. Therefore, the second stirring mechanism 3b will not be introduced in detail here.

[0044] The third stirring mechanism 3c includes a third stirring motor 31c arranged on the bucket cover 2b. The output end of the third stirring motor 31c is connected with a third stirring rod 32c, and the bottom of the third stirring rod 32c is connected with a third stirring paddle 33c. The third stirring paddle 33c includes a mounting sleeve 331c, and the mounting sleeve 331c extends outward and upward to form a plurality of arc-shaped stirring blades 332c, and the plurality of stirring blades 332c are connected by an annular connecting piece 333c. The stirring speed of the third stirring mechanism 3c is less than the stirring speeds of the first stirring mechanism 3a and the second stirring mechanism 3b. The difference of the third stirring mechanism 3c lies in the design of the stirring blades 332c, which can increase the stirring area. Through the design of the multiple stirring mechanisms 3, the stirring space in the stirring barrel 2 can be fully covered. At the same time, there is a speed difference between the third stirring mechanism 3c and the first stirring mechanism 3a and the second stirring mechanism 3b, which can cause a differential speed of the raw material flow during stirring and increase the stirring uniformity. Therefore, the setting of the stirring mechanism 3 in this application can improve the stirring uniformity and the stirring efficiency.

[0045] Further, please continue to refer to Figure 1 and Figure 4 , the barrel body 2a is of a double-layer structure. The upper end of the barrel body 2a is connected with a water inlet pipe 2d, and the lower end is connected with a water outlet pipe 2e. The water inlet pipe 2d and the water outlet pipe 2e are connected with an external heating device to form circulating water to heat or cool the raw materials in the barrel body 2a. A discharge port is also provided at the bottom of the barrel body 2a, and a discharge pipe 2f is connected to the discharge port. A diaphragm pump 9 is provided on the discharge pipe 2f to send out the raw materials. At the same time, a ladder 10 is provided on one side of the frame 1 to facilitate the operator's feeding and the cleaning of the stirring barrel 2 and the stirring mechanism 3.

[0046] The working principle of the present utility model is as follows:

[0047] Please refer to Figures 1 to 5When stirring the battery raw materials, first, the driving cylinder 7 drives the sliding mechanism 6 and the bucket cover 2b to move upward to the set position simultaneously, and then the limit cylinder 8 inserts the limit pin into the limit hole 1c to fix the bucket cover 2b. Then, the battery raw materials are added into the stirring bucket 2 manually or automatically, weighed according to requirements, and the weight data is displayed on the controller 5. When quantitative stirring is not required, the battery raw materials can be directly added and weighed by the weighing mechanism 4 when the raw materials are sent to the next process. Then, the limit pin of the limit cylinder 8 is disengaged from the limit hole 1c, and the driving cylinder 7 drives the bucket cover 2b to move downward, and the stirring mechanism 3 is started to stir the battery raw materials. Therefore, the setting of multiple groups of stirring mechanisms 3 and the structural design of the stirring mechanism 3 can improve the uniformity and efficiency of the stirring of the battery raw materials. After stirring, the weighed battery raw materials can be sent to the next process for use.

[0048] When the stirring is completed, the bucket cover 2b can be opened, and the bucket cover 2b is moved upward to clean the stirring bucket 2 and the stirring mechanism 3. The split structure of the bucket body 2a and the bucket cover 2b improves the cleaning efficiency and makes the cleaning more thorough.
