Description

Technical Field

[0001] The utility model relates to the technical field of devices for papermaking machines, in particular to a soft pressure roller belt shell grinding device for papermaking machines. Background Art

[0002] Papermaking is an important invention of the working people in ancient China. There are two forms: machine-made and hand-made. The machine-made process is carried out continuously on a papermaking machine. The pulp suitable for paper quality is diluted with water to a certain concentration, and initially dehydrated on the wire part of the papermaking machine to form wet paper sheets, which are then squeezed and dehydrated, and then dried into paper. The machine-made paper has a pulp-net speed difference, which leads to uneven fiber distribution in the longitudinal and transverse directions. The hand-made paper does not have uneven fiber distribution in the longitudinal and transverse directions, which is especially reflected in the paper used for calligraphy and painting. However, when the ordinary automatic soft pressing roller for papermaking is used, when the external soft pressing layer is damaged, the entire structure needs to be replaced, which is a great waste of resources.

[0003] The existing soft pressure roller device is composed of a rear support frame, a dummy shaft head 1, a soft pressure roller body, a dummy shaft head 2, a front support frame 5, a universal joint 6, a grinding machine head and bolts. The device rotates with the grinding machine head, and the universal joint 6 drives the soft pressure roller body 3 installed with the dummy shaft heads 1 and 2 to rotate. The soft pressure roller body 3 is positioned and supported by the front support frame 5 and the rear support frame.
