Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking machines, and in particular relates to a ropeless paper guiding device for a papermaking machine. Background Art

[0002] A paper machine is a machine that processes a water suspension of paper pulp into paper. It mainly includes three main parts: forming, pressing, and drying. It is equipped with finishing, winding and transmission devices, as well as auxiliary systems such as pulp supply, pulp and white water circulation, vacuum, ventilation and exhaust, damaged paper handling and lubrication, and automatic control. According to different process, paper machines can be divided into different types, such as large paper machines for special paper production and general small paper machines. Ropeless paper drawing of paper machines is a new papermaking process. With the development of the papermaking industry, the original low-speed paper machines are gradually eliminated, and papermaking companies are developing towards high-speed paper machines. The paper drawing rope system has the problems of increased system wear and high cost of use in the use of high-speed paper machines. The success rate of paper drawing is not high due to the unstable plastic deformation of the paper drawing rope when it moves at high speed; low-weight paper such as toilet paper has been damaged under the friction of the paper drawing rope. The paper drawing rope system no longer meets the production needs of most paper machines, so a ropeless paper drawing device for use with paper machines is needed. Utility Model Content
