The sand grinding device for industrial paint production integrates stirring and dispersing with sand grinding, thereby improving production efficiency while saving costs. However, during the process of crushing the industrial paint raw materials by the sand grinding device for industrial paint production, the raw materials at the bottom of the container are not easy to contact with the crushing blade, and uneven and insufficient crushing is likely to occur. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a sand grinding device for industrial paint production, which effectively solves the deficiencies of the prior art.

[0005] The purpose of the utility model is achieved through the following technical solutions: a sanding device for industrial paint production, comprising an industrial paint sanding bin, a rotating shaft is rotatably connected to the center of the inner wall of the industrial paint sanding bin, a plurality of crushing blades are fixedly connected to the outer side of the upper half of the rotating shaft, a filter is fixedly connected to the middle of the inner wall of the industrial paint sanding bin, a plurality of electric vibrating hammers are arranged below the filter, and a grinding block is fixedly connected to the bottom of the rotating shaft.

[0006] Optionally, a motor is fixedly connected to the center of the top of the industrial paint sanding bin, the output end of the motor is fixedly connected to the top of the rotating shaft, and the rotating shaft is rotatably connected to the middle of the filter.

[0007] The above technical solution is adopted: by setting a motor-driven rotating shaft inside the industrial paint sand grinding bin, the crushing blades and grinding blocks on the rotating shaft are driven to rotate, the industrial paint raw materials are crushed and ground, and the industrial paint raw materials are fully sanded and crushed.

When the crushing blades are crushing the industrial paint raw materials, the electric hammers hit the filter to make it vibrate, thereby speeding up the efficiency of the filter in screening small-particle raw materials. When there are fewer industrial paint raw materials on the filter, the large-particle raw materials remaining on the filter can be vibrated up to make them contact with the crushing blades again for crushing, thereby avoiding the situation in which the large-particle raw materials at the bottom are easily not crushed sufficiently during the crushing process. A hammer plate is arranged above the electric vibration hammer, which can drive the filter to vibrate when it is hit by the electric hammer, thereby avoiding the situation in which the vibration hammer directly acts on the filter and causes damage.

[0018] 3. The sand grinding device for industrial paint production can avoid the situation where the industrial paint raw materials filtered by the filter are accumulated on the support ring, resulting in the material remaining in the sand grinding bin and inconvenient to discharge, by setting grinding blocks on the bottom inner wall of the industrial paint grinding bin.

The positions of the hammer plates 9 correspond to the positions of the electric vibration hammers 5, and the output end of the electric vibration hammer 5 fits with the bottom of the hammer plate 9. By arranging a plurality of electric hammers 5 at the bottom of the filter 4, in the process of the crushing blades 3 crushing the industrial paint raw materials, the electric hammers 5 hammer the filter 5 to make it vibrate, thereby accelerating the efficiency of the filter 4 in screening small particle raw materials. When there are fewer industrial paint raw materials on the filter 4, the large particle raw materials remaining on the filter 4 can be vibrated up and made to contact with the crushing blades 3 again for crushing, thereby avoiding the situation that the large particle raw materials at the bottom are easily crushed insufficiently during the crushing process. A hammer plate 9 is arranged above the electric vibration hammer 5, which can drive the filter 4 to vibrate when being hammered by the electric hammer 5, thereby avoiding the situation that the vibration hammer directly acts on the filter 4 and causes damage.

When the crushing blades 3 are crushing the industrial paint raw materials, the electric hammers 5 hammer the filter 5 to make it vibrate, thereby accelerating the efficiency of the filter 4 in screening small-particle raw materials. When there are fewer industrial paint raw materials on the filter 4, the large-particle raw materials remaining on the filter 4 can be vibrated up to make them contact with the crushing blades 3 again for crushing, thereby avoiding the situation in which the large-particle raw materials at the bottom are easily crushed insufficiently during the crushing process. A hammer plate 9 is arranged above the electric vibration hammer 5, which can drive the filter 4 to vibrate when being hammered by the electric hammer 5, thereby avoiding the situation in which the vibration hammer directly acts on the filter 4 and causes damage.
