[0002] The so-called paint is used to coat the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the coated object. It is usually a viscous liquid prepared with organic solvents or water, mainly resin, oil, or emulsion, with or without pigments, fillers, and corresponding additives. Various raw materials need to be mixed and stirred during the production process, so a stirring device is required.

[0003] For example, the Chinese patent number CN218741796U is a weighable stirring device. In this utility model, the material weight is counted by a weighing sensor, so as to achieve accurate material control and stirring. The weighing sensor is located outside the stirring barrel, and the stirring barrel is weighed when connected to the stirring barrel support block. However, this setting allows the staff to only know the weight of the material in the current stirring barrel. In the process of continuously adding various raw materials, the subsequent measurement of the raw material weight is more cumbersome and requires repeated calculations, which reduces the convenience of use and is not conducive to user use. Therefore, a paint stirring device with automatic weighing function is proposed to solve the above problems. Utility Model Content

[0035] It should be noted that this section is intended to provide a background or context for the implementation methods stated in the claims, and detailed descriptions of known functions and known components are omitted. At the same time, fixed and movable installations are determined according to actual application methods. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art because it is included in this section.

[0036] When implementing, follow these steps:

[0037] 1) First start the annular pressure sensor 504, and then put the raw materials into the material storage barrel 507;

[0038] 2) Then, as the amount of raw materials in the container 507 increases, the weight of the entire container 507 increases, thereby causing the pressure value detected by the annular pressure sensor 504 to change;
