Problems solved by technology

[0004] 2. No felt length compensation
Due to the fact that within a felt circle, the length of the felt changes when the roller moves, and when the felt is thin, it is easy to damage the felt

Embodiment

[0018] Embodiment: A constant tension micro-compensation trolley device for a felt tensioner of a papermaking machine, including a trolley 1, a slider 2 and a pneumatic tire 3, the trolley can be positioned and slid in a straight line on the guide rail of the felt tensioner, and the slider can be Do linear positioning sliding on the trolley, the trolley is parallel to the sliding direction of the slider, the upper part of the slider is fixed with a bearing seat 4 supporting the felt roller, one end of the pneumatic tire is fixed with the slider, and the other end of the pneumatic tire is fixed with the trolley. When the tire is inflated, it stretches to push the slider to slide (when the trolley device moves to a certain position, the felt has a certain tension, but at this time the tension is smaller than required, and the pneumatic tire starts to inflate, thereby pushing the slider and The bearing seat starts to move in a straight line relative to the trolley, and the directi...

Abstract

The invention discloses a constant tension micro-compensation trolley device used for a papermaking mechanical felt tensioning machine, which comprises a trolley, a sliding block and a pneumatic tyre. The trolley can do linear positioning slide on a guide rail of the felt tensioning machine; the sliding block can do linear positioning slide on the trolley; a bearing seat which supports a felt roller is fixed on the upper part of the sliding block; one end of the pneumatic tyre is fixed with a position of the sliding block, and the other end of the pneumatic tyre is fixed with the position of the trolley; and the pneumatic tyre extends to drive the sliding block to slide during inflating. The embodiment adopts the pneumatic tyre to provide tensile force; the tensile force of the pneumatic tyre is determined by pressure of compressed air; when the pressure of the compressed air is adjusted, the tensile force can play a role of constant tension to realize constant tension control; and when felt is loosened or tightened, the pneumatic tyre correspondingly extends or shortens to play a role of micro-compensation because of the self-adjustment effect of the pneumatic tyre.

Description

technical field [0001] The invention relates to a device for a felt tensioner of a papermaking machine, in particular to a constant tension micro-compensation trolley device for a felt tensioner of a papermaking machine. Background technique [0002] The felt tensioner is a part in the press section and drying section of the papermaking machinery. Its main function is to tension the felt and provide the pre-tension force of the felt, so that the roller without drive can run under the tension of the felt, and at the same time make the felt open and smooth. It will not produce folds, but paper defects. On low-speed paper machines, the general felt tensioning device does not have constant tension, and they generally have the following problems: [0003] 1. Unable to control the tension. When electrically tensioning, the operator often jogs the operation and performs felt tensioning based on experience. When the felt is too tight, the load of the guide roller bearing will inc...
