Recently, information released by the National Intellectual Property Administration indicates that Anhui Yingchuan New Materials Technology Co., Ltd. has successfully obtained a patent titled "Vertical Color Masterbatch Sieving Device." Its authorization announcement number is CN 222678695 U, and the patent application date was April 2024.

This patent relates to a vertical color masterbatch screening device, which is ingeniously designed. Its main body is a vertical screening box. The inner side walls of the screening box are symmetrically provided with first limiting grooves. In the middle of the inner walls of the first limiting grooves, first sliding rods are fixedly installed. On the outer walls of the first sliding rods, there are slidingly connected first sliding blocks. The upper and lower ends of the outer walls of the first sliding blocks are welded with first springs, which are welded to the middle of the inner walls of the first limiting grooves. The middle part of the first springs surrounds the outer walls of the first sliding rods.

It is understood that during actual use, when the color masterbatch falls inside the sieve net, under the impact of its own gravity, in conjunction with the elastic potential energy of the first slider rod, as well as the sliding effect of the first slider rod and the first slider block, it can perform a sieving operation on the color masterbatch that has fallen inside the sieve net. This unique design significantly improves the sieving efficiency. Moreover, this device only requires a vertical classification box to achieve its function, without the need for a large area, effectively ensuring high work efficiency during the use of the device. It has brought about a new technological breakthrough to the field of color masterbatch sieving.
