Description

Technical Field

[0001] The present invention relates to the technical field of production equipment for regenerated cellulose membranes, and particularly to a method for treating the surface of a roller of a regenerated cellulose functional membrane. Background Art

[0002] With the development of society, the demand for food packaging by people is also increasing day by day. Moreover, with the gradual increase of people's awareness of environmental protection, as an environmentally friendly and degradable packaging material, the regenerated cellulose functional membrane has also been recognized by more people, and its market share has gradually increased accordingly.

[0003] The regenerated cellulose functional membrane is a regenerated film material made from natural cellulose as the raw material through specific processing procedures such as alkalization, xanthation, and forming. During the production process of the regenerated cellulose functional membrane, due to reasons such as its easy moisture absorption, drying shrinkage, and tension traction, longitudinal scratches and bulges are likely to appear on the surface of the roller of the regenerated cellulose functional membrane. During the winding process, these scratches and bulges are likely to gradually accumulate at the same position, resulting in the irregularity of the surface of the regenerated cellulose functional membrane, which will seriously affect the appearance and quality stability of the product.

[0004] Therefore, it is an urgent problem to be solved at present to research and design a method for treating the surface of the roller that can eliminate scratches and bulges on the regenerated cellulose functional membrane during the winding process, ensure the flatness of the regenerated cellulose functional membrane, and improve the appearance and quality stability of the product. Summary of the Invention

[0005] For the problems existing in the prior art, the present invention provides a method for treating the surface of a roller of a regenerated cellulose functional membrane. The controller controls the second driving member to drive the second moving seat and the detecting member to randomly swim along the second direction. The detecting member can measure the position of the edge of the regenerated cellulose functional membrane in real time. The controller controls the first driving member to drive the first moving seat to move along the second direction, so that the position of the edge of the regenerated cellulose functional membrane matches the real-time position of the second moving seat, that is, even if the regenerated cellulose functional membrane moves irregularly horizontally during the winding process, the traction tension of the regenerated cellulose functional membrane during the winding process is no longer fixed at a certain specific position, avoiding the gradual accumulation of scratches and bulges at the same position, thereby ensuring the flatness of the surface of the regenerated cellulose functional membrane and improving the appearance and quality stability of the product.

[0060] Step S2: The controller can obtain the real-time position information of the second moving seat 31 based on the second driving member 32, and the controller can receive the real-time position information of the edge of the regenerated cellulose functional film measured by the detecting member 33.

[0061] Step S3: The controller controls the first driving member to drive the first moving seat 21 to move along the second direction within the second amplitude range according to the real-time position information of the second moving seat 31 and the real-time position information of the edge of the regenerated cellulose functional film, so that the edge of the regenerated cellulose functional film moves towards the direction close to the real-time position of the second moving seat 31; in actual use, either one side edge of the regenerated cellulose functional film and a specific point on the second moving seat 31 can be located in the same vertical plane parallel to the first direction, or one side edge of the regenerated cellulose functional film and a specific point on the second moving seat 31 can maintain a constant distance in the second direction; wherein, the second amplitude range is the moving range of the first moving seat 21 limited by the two first limit sensors 13.
