Dual-grey paper fixing device for paper making plant laboratory

Abstract

The invention discloses a dual-grey paper fixing device for a paper making plant laboratory. The device comprises a fixed base, a first iron bar, a second iron bar, a left spring cotton, a right spring cotton, a left torsion-resistance spring and a right torsion-resistance spring, a first attracting magnetic strip and an attracting magnetic strip are arranged on the fixed base, a left pressing clamp is arranged on a left fixing plate, a left rotating s haft is connected between the left pressing clamp and the left fixing plate, the left spring cotton is arranged on the left pressing clamp, a right pressing clamp is arranged on a right fixing plate, a right rotating shaft is connected between the right fixing plate and the right pressing clamp, the right spring cotton is arranged on the right pressing clamp, fixed bolts are arranged on the left side and the right side of the fixed base, the left torsion-resistance spring is arranged in the left rotating shaft, and the right torsion-resistance spring is arranged in the right rotating shaft. The iron bars can be conveniently placed, absorbing properties of two structural parts can be improved, pressing force of the two structural parts can be improved, and the dual-grey paper can be more firmly placed on the fixing device.

Description

technical field [0001] The invention relates to the technical field of a fixing device for a laboratory, in particular to a double gray paper fixing device for a laboratory of a paper mill. Background technique [0002] In the existing technology, the factory transports the processed finished products to other places for further processing or to flow into the market, but in the process of transportation or sales, it is necessary to use a large amount of double gray paper for packaging. To play the dual role of anti-fall and protection, the existing double-gray paper uses wood fiber paper as the coating base material, coats the gas phase corrosion inhibitor on the surface, and compound a layer of PE film on the other side of the paper to prevent corrosion. To enhance its mechanical strength and waterproof performance, when producing these double gray papers in the factory, it is usually necessary to carry out various checks in the laboratory of the paper mill. In the existing...

[0002] In the existing technology, the factory transports the processed finished products to other places for further processing or to flow into the market, but in the process of transportation or sales, it is necessary to use a large amount of double gray paper for packaging. To play the dual role of anti-fall and protection, the existing double-gray paper uses wood fiber paper as the coating base material, coats the gas phase corrosion inhibitor on the surface, and compound a layer of PE film on the other side of the paper to prevent corrosion. To enhance its mechanical strength and waterproof performance, when producing these double gray papers in the factory, it is usually necessary to carry out various checks in the laboratory of the paper mill. In the existing technology, in the laboratory, the double dust The paper fixing device is essentially to use a smooth plane, place the double gray paper on the plane, and complete various experiments. When checking the waterproof performance of the double gray paper, this double gray paper placement method can be completed. This test work, but when checking its mechanical strength, it is difficult to fix the double gray paper on the plane because there is no fixing device around the double gray paper. During the experiment, the double gray paper deviates from the working position, making it difficult to accurately detection
