45-degree stretching softening and curving producing technology and device for paper-base sanding belts

Abstract

The invention relates to an improved technology of grinding tool producing technologies and discloses a 45-degree stretching softening and curving producing technology and a device for paper-base sanding belts. The 45-degree stretching softening and curving producing technology and a device for the paper-base sanding belts are characterized in that after solidification is carried out on the paper-base sanding belts, the paper-base sanding belts are fed into a stretching softening and curving machine for 45-degree stretching softening and curving, the paper-base sanding belts are operated horizontally in a longitudinal mode, the paper-base sanding belts are operated horizontally in a transverse mode after passing through a first softening and curving rod arranged at 45 degrees, the paper-base sanding belts are operated horizontally in a longitudinal mode after passing through a second softening and curving rod arranged at 45 degrees, and 45-degree stretching, softening and curving are achieved. The stretching flexibility machine comprises a machine frame which is provided with a paper feeding roller, a paper receiving roller, a feeding barrel and a receiving barrel. A rotation shaft of the receiving barrel is connected with a driving device in a transmission mode. The two flexibility rods arranged corresponding to conveying directions of the paper feeding roller and the paper receiving roller in a 45-degree-angle mode are arranged on the left side of the machine frame. The defects that paper-base sanding belts after adoption of a traditional 90-degree stretching softening and curling technology is prone to frangibility and curving and not enough in toughness softening and curving are solved by the 45-degree stretching softening and curving producing technology and a device for the paper-base sanding belts, and the 45-degree stretching softening and curving producing technology and a device for the paper-base sanding belts are suitable for production of high-performance sanding paper and paper-base sanding belts.

Description

technical field [0001] The invention relates to an improvement technology for the production process of abrasive tools, in particular to a production process method and equipment for a paper-based abrasive belt with a 45° looseness and flexibility. Background technique [0002] At present, most of the domestic manufacturers use 90° loose flex for the loose flex of the paper-based abrasive belt after curing (see figure 1 , the paper-based abrasive belt 1 runs horizontally at first, and becomes vertically downward through the flex bar 2, that is, 90° flex, and then changes direction to run horizontally through the flex bar), in order to achieve a certain loosening and flex quality, often It is a 90° stretch and soft bend many times. But in the end, either the toughness and flexibility of the paper-based abrasive belt cannot meet the requirements, or the paper-based abrasive belt has not solved the quality problems of brittle fracture and curling. This repeated process consum...
