Description

Technical Field

[0001] This utility model relates to the field of sandpaper production technology, and in particular to an abrasive screening and impurity removal device for the production of dust-free ceramic dry sandpaper. Background Technology

[0002] Abrasive screening and impurity removal equipment plays a crucial role in the production of dust-free ceramic dry sandpaper, mainly in the following aspects: 1) In the production process of dust-free ceramic dry sandpaper, the quality of the abrasive directly affects the grinding effect and durability of the sandpaper. Abrasive screening and impurity removal equipment can accurately screen and classify the abrasive, ensuring that the size, shape, and hardness of the abrasive meet production requirements. Through screening, excessively large or small abrasive particles, as well as impurities mixed in the abrasive, such as dust and debris, can be removed, thereby ensuring the purity and consistency of the abrasive. 2) The use of abrasive screening and impurity removal equipment can significantly improve production efficiency. Traditional screening methods often require manual intervention, which is time-consuming and inefficient. Modern screening equipment adopts automation and mechanization technology, which can quickly and accurately complete the screening and impurity removal work, greatly shortening the production cycle. At the same time, the efficient operation of the equipment also reduces errors and delays caused by manual operation, improving the stability and reliability of the overall production line. 3) The quality requirements for dust-free ceramic dry sandpaper are extremely high; any tiny impurities may affect the grinding effect and surface finish of the sandpaper. Abrasive screening and impurity removal equipment can effectively remove impurities from abrasives, ensuring that sandpaper is not contaminated during the production process. This not only improves the quality stability of sandpaper but also extends its service life, meeting customers' demands for high-quality sandpaper.

[0003] Existing abrasive screening and impurity removal equipment for cleanroom ceramic dry sanding paper production has shortcomings. To obtain abrasives within a selected particle size range, it requires two layers of sieve plates with different mesh sizes. After screening, abrasives within the target particle size range cannot be automatically removed, and large and small abrasives outside the range cannot be automatically transferred, hindering continuous batch screening and impurity removal operations. Therefore, optimization and improvement of existing abrasive screening and impurity removal equipment for cleanroom ceramic dry sanding paper production are necessary. Utility Model Content
