Problems solved by technology

[0002] At present, the paper rolls or other rolls used in the industrial production of roll paper or roll film are made of strong fiber paper sizing. Since the strong fiber paper needs to be made of high-quality wood, it will cause damage to forest resources and is not good for environmental protection.

Abstract

The invention discloses a stamping semi-cylindrical die which comprises an upper die and a lower die, wherein the upper die consists of a movable die core and an upper die holder; the movable die core consists of a die core seat and a plurality of male die cores, the die core seat is fixedly connected with the upper die holder, the male die cores are positioned in the die core seat, the male die cores are in movable fit connection with the die core seat, and a compression spring is arranged between each of the male die cores and the upper die holder; and the lower die consists of a lower die holder and a blanking control device. Wood shavings or fibers and the like of waste materials are mixed with resin by using a hot press and the stamping semi-cylindrical die and thermally cured and molded to manufacture stamping semi-cylinders, and the stamping semi-cylinders are combined into a stamping cylinder serving as a paper coiling cylinder for paper production or other coiling cylinders. The consumption of strong fiber paper is reduced, the loss of forest resources is reduced, and limited forest resources are protected.

Description

technical field [0001] The invention relates to a mold for manufacturing a paper roll, in particular to a mold for manufacturing a molded half cylinder. Background technique [0002] At present, the paper rolls or other rolls used in the industrial production of roll paper or roll film are made of strong fiber paper sizing. Since strong fiber paper needs to be made of high-quality wood, it will cause damage to forest resources and is not conducive to environmental protection. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a molded semi-cylindrical mould, which uses shavings or fibers of waste materials to manufacture a molded semi-cylindrical, and then uses the molded semi-cylindrical to combine into a molded circular roll, which is used as a paper for paper production. Reels or other reels are used to reduce the consumption of strong fiber paper, reduce the loss of forest resources, and ...
