Papermaking drying cylinder mechanism

Abstract

The invention relates to the technical field of papermaking, and specifically relates to a papermaking drying cylinder mechanism that comprises a machine frame; a plurality of drying cylinder assemblies installed on the machine frame; a driving assembly is in transmission connection with any drying cylinder assembly, a bearing assembly is installed on the periphery of the whole drying cylinder assembly, and a brake assembly is installed on the driving assembly, wherein the drying cylinder assemblies comprise the upper drying cylinder assembly and the lower drying cylinder assembly which are arranged in an up-down staggered mode. The upper drying cylinder assembly and the lower drying cylinder assembly each comprise a drying cylinder body, a center shaft axially penetrating through the drying cylinder body and a transmission gear installed at the front end of the center shaft. The driving assembly comprises a motor, a driving shaft fixedly connected with the output end of the motor anda driving gear fixedly connected with the other end of the driving shaft, and the driving gear is in meshing transmission with any transmission gear; the driving shaft is sleeved by the brake assembly. According to the papermaking drying cylinder mechanism, a paper web can be dried and conveyed stably, the tension of paper can be better adjusted, and the production quality of the paper is improved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a drying cylinder mechanism for papermaking. Background technique [0002] The papermaking process usually includes a series of treatments such as forming, pressing, pre-drying, sizing / coating (surface treatment) post-drying, calendering, and rolling. In the drying stage after pressing dehydration or sizing coating, the existing drying device generally consists of multiple drying cylinders, and each drying cylinder is driven by a different motor to drive the paper, thereby drying the paper. [0003] Because there will be certain errors in the specifications of each drying cylinder in the drying cylinder device, there will be a speed difference between the drying cylinders and the drying cylinders when they rotate, which will cause the paper web to not be driven smoothly, and the tension of the paper cannot be well adjusted. Thereby affecting the production quality of paper. ...

Problems solved by technology

[0003] Because there will be certain errors in the specifications of each drying cylinder in the drying cylinder device, there will be a speed difference between the drying cylinders and the drying cylinders when they rotate, which will cause the paper web to not be driven smoothly, and the tension of the paper cannot be well adjusted. Thus affecting the quality of paper production

On the other hand, when the drying cylinder device needs to slow down or shut down, it is even more difficult for the operator to grasp the tension of the paper, and the situation of paper breakage or warping occurs frequently

In the prior art, there are very few processes that equip the drying device with a brake device, w
