The invention discloses a compressing mechanism for a cylindrical refiner. The compressing mechanism for the cylindrical refiner comprises a lava flybar; a pulp feeding impeller and a pulp discharging impeller are respectively clung to two end surfaces of the lava flybar; pressing covers are respectively mounted at the outer sides of the pulp feeding impeller and the pulp discharging impeller by a pressing manner; a hollow transmission shaft is pressed at the outer side of each pressing cover; angular rods capable of swinging leftwards and rightwards are respectively hinged into the two transmission shafts; guide grooves are respectively formed in the outer side surfaces of the pressing covers; air cylinders are respectively mounted in the transmission shafts; piston rods of the air cylinders are downwards arranged, and the end parts of the piston rods are hinged to inner ends of the corresponding angular rods; the outer ends of the angular rods are respectively inserted into the guide grooves in corresponding cover plates. The compressing mechanism for the cylindrical refiner has the advantages that the air cylinders drive the angular rods to swing leftwards and rightwards, and the inner ends of the angular rods under swinging apply different compressing forces to the corresponding pressing covers so as to enable the cylindrical refiner to be adapted to different working environments, and the compressing effect is obvious.
Description
Technical field: [0001] The invention mainly relates to the technical field of a cylindrical refiner, in particular to a pressing mechanism used in a cylindrical refiner. Background technique: [0002] The knife roll used for cylindrical refining is a basalt knife roll, and the two ends of the basalt knife roll are respectively press-fitted with a pulp inlet impeller and a pulp outlet impeller, and the pulp inlet impeller and the pulp outlet impeller are connected to the main shaft. This structure uses the mechanism that presses the impeller, the impeller and the basalt knife roller. The mechanism of the prior art has the defect of unreliable clamping. Invention content: [0003] The object of the present invention is to make up for the defects of the prior art, and to provide a compacting mechanism used in a cylindrical refiner, which has the advantage of good compacting effect. [0004] The present invention is achieved through the following technical solutions: [000...
