[0002] Sizing agent is a papermaking additive, which is mainly divided into internal sizing and surface sizing. Sizing on paper can improve the paper's water resistance, oil resistance, printing ink resistance and other properties, and at the same time improve the smoothness, hydrophobicity and printing adaptability. When preparing and using sizing agent, a mixer is needed to stir various raw materials.

[0003] The utility model with Chinese patent application number CN202023326066.X discloses a vertical mixer for producing liquid dissolving agent. The utility model is provided with a mixing barrel, a bottom tank, a limit plate and a spring. When the mixing barrel is in use, the bottom tank is buckled on the limit plate of the machine base, and the limit rod inside the limit plate is inserted into the limit tank to fix the mixing barrel, thereby increasing the stability of the mixing barrel. When the mixing barrel needs to be moved down from the machine base, the electromagnet on the inner wall of the inner tank can be started, and the limit rod will be attracted by the magnetic force of the electromagnet and will be separated from the limit tank and retracted into the inner tank, thereby releasing the limit on the mixing barrel, and then the mixing barrel can be moved down from the machine base, which is more convenient.
