Sizing roller for paper machine

Abstract

A sizing roller for a paper machine comprises a left cylinder and a right cylinder, the same supporting pipe is arranged in the left cylinder and the right cylinder, one end of the supporting pipe is fixedly connected with the left cylinder, the other end of the supporting pipe is connected with the right cylinder through a plurality of first telescopic rods, a nut is fixedly installed in one end of the supporting pipe, and an external threaded pipe is installed in the nut in a threaded fit mode. The external threaded pipe is rotatably installed in a preformed hole of the right cylinder, one end of a first spring rod is fixedly connected in the external threaded pipe, the other end of the first spring rod is rotatably connected with one end of a moving pipe, a plurality of through holes are formed in the side face of the left cylinder, second spring rods are arranged in the through holes in an inserted and matched mode, and the inner ends of the second spring rods are fixedly connected with the moving pipe. The sizing roller for a paper machine is simple in structure and ingenious in conception, the length of the roller core can be adjusted, supporting of rubber layers with different lengths can be met, the adjusted roller core is free of hollowed-out positions, therefore, the rubber layers can be well supported, the market requirement can be met, and the sizing roller for a paper machine is suitable for popularization.

Description

technical field [0001] The invention belongs to the field of rubber rollers, in particular to a rubber sizing roller for a paper machine. Background technique [0002] The rubber roller is a roller-shaped product made of metal or other materials as the core and vulcanized rubber on the outside. Rubber rollers are widely used in various mechanical equipment such as printing and dyeing equipment, textile equipment, environmental protection equipment, and papermaking equipment. The existing The rubber roller is generally an integral structure. In use, a roller core can only correspond to a rubber layer of one length, resulting in the disadvantage of reduced flexibility in use. Even if the length of the roller core can be adjusted, the middle part of the adjusted roller core Hollow out, the support effect on the adhesive layer is reduced, which cannot meet the actual needs, so we invented a sizing roller for paper machines. Contents of the invention [0003] The invention pro...
