Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a stirring device used for adhesives. Background Art

[0002] Sand core adhesive is used in the foundry industry to repair and assemble sand cores, as well as to bond and fix them when positioning the sand cores. The foundry industry uses a lot of sand core adhesives, which are high-temperature resistant inorganic adhesives made by mixing sodium silicate, bauxite, mullite powder, quartz powder, clay, etc. as raw materials. They have the characteristics of strong adhesion, easy operation, and high strength.

[0003] In the specific production process of adhesives, various raw materials need to be added into a mixing barrel first, and then stirred using a stirring device. Figure 1 The stirring device used in the production includes a column 1, which is vertically installed on the ground. A hydraulic lifting mechanism 2 is arranged on the column 1. A lifting platform 3 is installed at the output end of the hydraulic lifting mechanism 2. A stirring motor 4 is installed on the lifting platform 3. A stirring shaft 5 is rotatably connected to the lifting platform 3. The stirring shaft 5 is transmission-connected to the output shaft of the stirring motor 4. A dispersion disk 6 is arranged at the bottom of the stirring shaft 5. A control panel 7 for controlling the stirring motor 4 and the hydraulic lifting mechanism 2 is also arranged on the column 1. In specific use, the hydraulic lifting mechanism 2 is started, and the hydraulic lifting mechanism 2 drives the lifting platform 3 to move upward. When the dispersion disk 6 rises to a suitable position, the hydraulic lifting mechanism 2 is closed, and the stirring barrel containing the adhesive raw material is moved below the dispersion disk 6. Then, the hydraulic lifting mechanism 2 is started again, and the hydraulic lifting mechanism 2 drives the lifting platform 3 to move downward, so that the dispersion disk 6 extends into the inside of the stirring barrel. Then, the stirring motor 4 is started, and the rotation of the output shaft of the stirring motor 4 drives the stirring shaft 5 to rotate, and then drives the dispersion disk 6 to rotate. The dispersion disk 6 stirs the adhesive raw material in the stirring barrel during the rotation process.

[0004] When the dispersion disk 6 rotates, centrifugal force is generated and acts on the material on the dispersion disk 6. The centrifugal force will project the material outward to form a vortex-like motion. However, due to the high viscosity of the adhesive, it is difficult for the dispersion disk 6 to form a good vortex motion during rotation, and the stirring effect is poor. Utility Model Content

[0035] A transmission assembly is provided between the rotating shaft 10 and the stirring shaft 5. Under the transmission action of the transmission assembly, the rotation of the stirring shaft 5 will drive the rotating shaft 10 to rotate.

[0037] When in use, the hydraulic lifting mechanism 2 is started, and the hydraulic lifting mechanism 2 drives the lifting platform 3 to move upward. When the stirring shaft 5 rises to a suitable position, the hydraulic lifting mechanism 2 is closed, and the stirring barrel filled with the adhesive raw material is moved below the stirring shaft 5. Then the hydraulic lifting mechanism 2 is started again, and the hydraulic lifting mechanism 2 drives the lifting platform 3 to move downward, so that the stirring shaft 5 extends into the interior of the stirring barrel. Then the stirring motor 4 is started, and the rotation of the output shaft of the stirring motor 4 will drive the stirring shaft 5 to rotate, and then drive the first spiral blade 8 to rotate.
