Abstract

The invention relates to the field of paperboard manufacturing, in particular to a paperboard production process, which uses a stuff grinder, wherein the stuff grinder comprises an inspection board, aguide structure, a grinding structure, a water inlet valve, a material feeding structure, a shell, a driving structure and an anti-blocking structure; the bottom end of the shell is provided with thedriving structure for driving; the driving structure is connected to the grinding structure for grinding in the shell; the bottom end of the grinding structure is provided with a guide structure forguiding flow; the anti-blocking structure for feeding is arranged inside the grinding structure; the anti-blocking structure is connected to the material feeding structure, used for storing material,on the shell. The anti-blocking structure is connected with the grinding structure, the internal blockage of the grinding structure is effectively prevented, the grinding structure uniformly grinds the paper raw material, the material feeding structure is connected with the grinding structure, and the material is conveniently controlled to enter the interior of the grinding structure at a uniformspeed, which effectively prevents the material from being blocked in the material feeding structure, the quality of the material feeding is improved, and the material feeding speed of the raw materialcan be adjusted.

Description

technical field [0001] The invention relates to the field of cardboard manufacturing, in particular to a cardboard production process. Background technique [0002] Cardboard, also known as cardboard, is a thick paper sheet made of various pulps and interwoven fibers. Cardboard is widely used in article packaging, which can effectively prevent damage to packaged articles and make transportation more convenient. In the process of cardboard manufacturing It is necessary to grind the raw materials, and the refiner refers to the machine that grinds the processed raw materials into a slurry. [0003] However, when the traditional pulping process grinds raw materials, it is easy to cause the internal blockage of the equipment and the blockage of the lower hopper, which affects the grinding quality, and the pulp is inconvenient to store. In view of this, the invention provides a kind of paperboard production technology, and it has the following characteristics: [0004] (1) A kin...
