Abstract

The invention provides a medium-consistency pulping mechanism which comprises a grinding head assembly, a grinding body bearing chamber assembly, a rack and a sealing structure which are arranged in a matched mode, the grinding body bearing chamber assembly comprises a grinding shaft, and the grinding head assembly is installed at one end of the grinding shaft; the grinding body bearing chamber is sleeved on the grinding shaft; the magnetic railing ruler is mounted on one side of the bearing chamber of the grinding body; the two sides of the grinding body bearing chamber are respectively connected to a rack guide rail sliding block; the grinding body bearing chamber is connected with the worm and gear lifting machine through a connecting frame arranged at the bottom; the far millstone bearing gland and the near millstone bearing gland are respectively arranged at two ends of the millstone body bearing chamber; the two spherical roller thrust bearings are mounted in the grinding body bearing chamber in a back-to-back manner; and the self-aligning roller bearing is sleeved on the grinding shaft and is arranged in the grinding body bearing chamber through a round nut and a lock washer for the round nut. According to the technical scheme, the structural design is simplified, the transmission capacity of force or torque is improved, the cutter feeding and retracting precision is improved, and jumping of the grinding disc during shafting rotation is avoided.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment for papermaking, in particular to a medium-consistency refining mechanism. Background technique [0002] In related technologies, the medium-consistency refining mechanism mainly relies on the grinding disc to grind the pulp delivered to the grinding body into fine pulp. The advancing and retracting devices of the medium-consistency refining mechanism adopt a worm gear structure, and the two grinding mills are adjusted by handwheels or servo motors. The gap and pressure between the sheets have the following technical defects: [0004] (1) The overall structure is complex, the manufacturing and processing costs are high, the manufacturing, processing and maintenance are complicated, and the transmission feed mechanism cannot transmit large forces or moments. [0005] (2) The feeding and retracting of the transmission feed mechanism is inaccurate, the grinding disc is prone to jump w...
