Description

Dust-binding paper roll with combined paper tube core Technical Field The utility model relates to the field of dust-binding paper rolls, in particular to a dust-binding paper roll with a combined paper tube core. Background The paper is a sheet material which is formed by filtering plant fibers on a porous mold to form a wet fiber layer through purification and dispersion of physical-chemical treatment and drying, is commonly used for writing, printing, packaging, cleaning and the like for application, and replaces traditional carriers such as bamboo slips, silk fabrics and the like. The dust-binding paper roll is a sticky roll-shaped cleaning tool, is generally cylindrical, is similar to a roller for painting a wall body, can conveniently and rapidly remove pollutants and dust on the surface of an object, avoids secondary pollution of a cleaning workshop, and is widely applied to industries such as circuit boards, liquid crystal displays, photoelectricity, semiconductors, precision printing and the like. The prior art CN210884717U specifically relates to a dust-binding paper roll based on a combined paper tube core, which comprises a winding drum, wherein the winding drum consists of a tube core and a dust-binding film, the length of the dust-binding film is greater than that of the tube core, and plugs are respectively plugged at two ends of the winding drum. According to the utility model, the plug seals the port of the winding drum, and supports the dust-binding film at the port, so that the dust-binding film at the port is prevented from collapsing and paper scraps fall out during use, and the quality of the paper roll is improved. However, the dust-binding paper roll with the paper tube core has the following problems that plugs are respectively plugged at two ends of a winding drum, the plugs are made of plastic, the paper roll is not environment-friendly in the later treatment due to the adoption of the plastic materials, and in the rolling process of the paper roll, the inner wall of the plug frequently rubs when the paper roll rolls due to the design of the plugs, so that plastic particles and scraps fall.
