Embodiment

[0044] According to the speed-up requirements of the 9# paper machine, adjust the lip plate of the paper machine, install the frequency converter for the cage vacuum pump and monitor the data of the upper roll of the paper machine and the motor. The process is as follows: On October 31, 2011, the lip plate of the 9# paper machine was installed 6.0mm was adjusted to 6.3mm and 7.5, and finally confirmed as 7.0. The paper machine produced 13.5g of base paper at 770 meters with poor forming, and it will run until November 3rd.

[0045] On November 3rd, the lip plate was adjusted from 6.3mm to 6.5mm and a cage vacuum pump inverter was installed. The paper machine produced 13.5g base paper at a speed of 770 meters, and the frequency of the cage vacuum pump was adjusted, which barely met the process requirements. The paper machine ran to November 9.

[0046] On November 9th, the lip plate was adjusted from 6.5mm to 7.5mm and the frequency converter of the cage vacuum pump was remove...

Abstract

The invention discloses a high-speed tissue paper-making machine with an improved structure. The high-speed tissue paper-making machine comprises a rack; the left side of the rack is provided with a pulp flow box of pulp feeding equipment, and the right side of the rack is provided with vacuum mesh cage of main dehydration equipment; a paper molding couch roller is arranged above the vacuum mesh cage; and the middle part of the rack is provided with a driving first vacuum carrier roller, a driven second carrier roller and a drying cylinder of dry equipment, which are connected in series by using coarse cloth and auxiliary internal and external coarse cloth rollers. According to the paper-making machine, the speed can be increased to 800 m / min, the tissue with specification of 13.5 g per cm<2> can be normally produced on the premise of the stable speed, and various physical indexes of the tissue can be met; the tension after the increasing of the speed is improved in comparison with the tension before the increasing of the speed; and moreover, the tension of the original paper is fluctuated less, so that the increasing of the speed has no adverse influence on the tension of the original paper.

Description

technical field [0001] The invention relates to papermaking equipment, which belongs to the technical field of tissue paper production, in particular to a high-speed tissue papermaking machine with improved structure. Background technique [0002] The structure of the paper machine is various, and generally consists of components such as flow conveying, forming, pressing, drying, finishing, coiling and transmission, and auxiliary systems and other supporting equipment. It is a machine that makes paper pulp water suspension that meets the requirements of papermaking through dehydration forming through filter screen, mechanical extrusion dehydration and drying. The paper machine includes three main parts of forming, pressing and drying to complete the above process, and is equipped with necessary finishing, coiling and transmission devices, as well as pulp supply, pulp and white water circulation, vacuum, ventilation and exhaust, damage Paper handling and lubrication, automat...
