Paper making felt setting machine

Abstract

The invention discloses a paper making felt setting machine which comprises a motor, a hot oil roller, a tensioning roller and a cutting and polishing device, wherein the motor drives the hot oil roller to rotate; a paper making felt is tensioned between the hot oil roller and the tensioning roller; the position of the cutting and polishing device is adjustable; when the cutting and polishing device is adjusted to be contacted with the surface of the paper making felt, the surface of the paper making felt is cut and polished. The paper making felt setting machine is provided with the cutting and polishing device, a mechanical polishing mode is adopted, the uneven surface of the paper making felt is cut and polished through the cutting and polishing device, felt mark is difficultly formed on the paper surface when the obtained paper making felt setting machine is used, the paper dehydration is uniform, and the quality of the paper is improved. The paper making felt setting machine is simple in structure and convenient to use, the hardened surface of the paper making felt subjected to heating treatment of the hot oil roller can be removed, and the paper dehydration efficiency is improved.

Description

technical field [0001] The invention relates to a papermaking felt setting machine. Background technique [0002] There is a process in the production process of paper-making blankets—acupuncture flocking. This process is to needle the carded fibers onto the base fabric by needle punching to make a semi-finished blanket. The equipment used for needle punching is called needle punching. Cashmere machine, in which the needles are arranged according to a certain rule. During the acupuncture process, the needles with barbs move up and down to bring the fibers on the surface of the blanket into the inside of the blanket, so that the fiber nets are intertwined with each other and combined with the base fabric in the form of rivets. . like figure 1 As shown, this process causes the felt to form an uneven surface, commonly known as needle puncture marks. When entering the nip together with the paper, different pressures are formed on the surface of the paper, causing uneven dehyd...

like figure 1 As shown, this process causes the felt to form an uneven surface, commonly known as needle puncture marks. When entering the nip together with the paper, different pressures are formed on the surface of the paper, causing uneven dehydration of the paper

When the traditional sizing machine is used to modify the surface of paper-making felts, it mostly uses infrared heat radiation or heating by hot oil rollers to make the surface of the felt smooth. , affecting the efficiency of paper dehydration
