Description

Technical Field

[0001] The utility model relates to the technical field of powder addition, in particular to a weight counterweight device for automatically adding powder to a coated sand production line. Background Art

[0002] The production line of coated sand usually consists of the following steps: the base sand (or other special sand) for making coated sand is first quantified, enters the heating system to reach the temperature requirement during mixing, and then enters the mixer. At the same time, the quantified additives (resin, hardener, calcium powder, etc.) are automatically put into the mixer in sequence according to the mixing procedure for stirring, and then the lumps are dispersed, the waste particles are screened out, and enter the cooling system. The finished coated sand is stored at a temperature before packaging. The coating effect of coated sand reflects the production quality. Heating and mixing operations are the main processes that affect the process. The temperature of the raw sand heating affects the mixing effect. When the hot sand enters the mixer, try to avoid heat loss to ensure the mixing effect, so that the parameters of the produced coated sand products can meet the design requirements. Design a hot sand machine that can heat quickly and evenly and a mixer that improves the mixing quality.

[0003] In the prior art, when quantitative coated sand filling is performed in the coated sand production line, the automatic filling effect is low, resulting in the inability to accurately weigh the amount of powder added. At the same time, the difference in the amount of powder added during the production process of the coated sand production line affects the overall production quality and reduces the production effect.

[0004] Therefore, in view of the shortcomings of the prior art, it is necessary to provide a counterweight device for automatically adding powder to a coated sand production line to solve the shortcomings of the prior art. Utility Model Content

The weight is set by operating the control system in the auger feeding mechanism to control the quality of the material delivered by the auger mechanism. Accurate data is obtained through visual weighing of the load-bearing sensor in the load-bearing sensing mechanism.

After the set time is reached, the pneumatic butterfly valve closes, and the control system switch set in the pneumatic butterfly valve controls the auger mechanism to continue feeding, and the work is automatically cyclically performed in sequence.

[0006] The above-mentioned purpose of the utility model is achieved through the following technical means.

The upper and lower ends of the connecting piece 8 are respectively connected to the feeding channel 7 and the weighing bucket 4.
