New wide-format cattle card board machine successfully put into operation in Guangdong

A new type of paper machine for copying kraft paperboard and kraft linerboard, which was developed by Xiangnan Yongjiayu Machinery Manufacturing Co., Ltd., was successfully put into operation at Guangdong Xinhui Yizhou Sugar Paper Factory Co., Ltd. Since its operation for more than one month since late March, it has produced good paper, and all technical performances have met the design requirements, with significant economic benefits.
The machine has absorbed some of the features of foreign advanced paper machines, compared with the domestic type of paper machine, the advantages are very obvious. The machine is designed for a daily output of 100 tons, a working speed of 120 to 180 meters per minute, a maximum copying width of 3300 millimeters, and a manuscript of 110 to 350 grams. The net department is made up of 4 pressure formers. The frame adopts a monolithic structure and is configured to move out of the device in the same cage. The change of the net is very convenient. The press section is equipped with three-roll two-compression zone compound press and two-pass positive press. Its structural feature is the horizontal arrangement of the vacuum press roll suction port, the water flow is smooth during the work, the vacuum suction efficiency is improved, the water content of the press press can be significantly reduced, and the process sheet is made Stable and easy to operate. The dryer section has 20 155mm dryers and 1 3000mm dryer. Dryer adopts enclosed gear transmission, concentrated oil lubrication dryer cylinder frame using box-shaped steel parts, smooth transmission work. The dry net adopts pneumatic automatic correction for easy operation. The transmission part adopts AC variable frequency speed regulation and subsection transmission. With AC frequency conversion motor, hardened gear reducer, work reliability.
The paper machine has a reasonable design, excellent product quality, and good papermaking performance. It is the ideal equipment for the technical transformation and development of small and medium-sized paper mills.
