Embodiment approach
[0022] As an embodiment of the present invention, the filter screen 5 is installed on the inner wall of the bottom of the lapping plate 21, and the filter screen 5 is arranged in a ring shape, which can filter the completely ground paint. When the raw material is ground to the required degree in the lapping area 2, it can pass through the filter screen 5, and the raw material that cannot pass through the filter screen 5 will be mechanically ground until it is completely ground.
[0023] As an embodiment of the present invention, the collection box 6 is installed on the outer wall of the bottom of the lapping plate 21, close to the position of the filter screen 5, the collection box 6 is ring-shaped, and the filtered paint directly falls into the collection box 6. The ground paint raw materials need to be collected. By setting the collection box 6, after the raw materials are completely ground, they can pass through the filter screen 5 and directly fall into the collection box 6...

The invention relates to the technical field of grinding devices, in particular to a macromolecule coating raw material grinding device. During operation, a motor drives a rotating shaft to rotate; the rotating shaft drives a centrifugal fine grinding cone plate and a centrifugal fine grinding cylindrical plate to rotate; a centrifugal device rotates to open with the rotating shaft and is contactwith the centrifugal fine grinding cylindrical plate to splay the centrifugal fine grinding cylindrical plate; the rotating shaft drives a reverse rotating mechanism to start to generate reverse rotation, and drives a fine grinding plate and a coarse grinding plate to rotate reversely to achieve the function of forward and reverse rotating grinding; raw material is added, and is broken in a coarsegrinding area to achieve the grinding effect to prepare for fine grinding; and the raw material falls in a fine grinding area after coarse grinding, and under the forward and reverse grinding by thefine grinding plate and the centrifugal fine grinding cylindrical plate, the grinding effect is greatly improved, and the raw material reaching grinding requirements falls in a collecting box througha filter screen. The problems of coating raw material getting stuck, unsatisfactory grinding effect and short service life are solved.
Description
technical field [0001] The invention relates to the related technical field of grinding devices, in particular to a grinding device for polymer coating raw materials. Background technique [0002] In the production and preparation of polymer water-based coatings, grinding the coating is an essential and important process. In the prior art, when the paint is ground, the paint is put into a grinding barrel with grinding media for grinding; but the existing grinding method has the following defects: the grinding media is easy to wear out, the service life is short, and it cannot be ground for a long time. Continuous work; 2. Due to the lack of primary crushing of the paint when feeding, some of the paint particles entering the grinding chamber are relatively large, which is not conducive to fully grinding the paint, so the quality of the grinded paint is also relatively poor. [0003] There are also some technical solutions about polymer paint grinding devices in the prior art...
