The utility model mainly provides a spiral paper winding tube, which mainly improves the strength of the paper tube and does not increase the wall thickness of the paper tube. Or, the strength of the paper tube is ensured under the condition of reducing the wall thickness of the current paper tube.

The specific structure of the spiral wound bobbin will be mainly described below.

Referring to fig. 1 to 11, in the embodiment of the present invention, the spiral roll paper cartridge includes at least one spiral roll paper layer 100, the spiral roll paper layer 100 includes a spiral roll paper base layer 110 and a rib forming structure 120 extending along the spiral roll paper base layer 110, the spiral roll paper layer 100 is connected to a roll paper connected thereto through an adhesive, and the spiral roll paper cartridge is formed by extrusion.

Specifically, in this embodiment, the spiral winding cylinder has a circular cross section, but of course, in some other embodiments, the spiral winding cylinder may have other shapes according to specific requirements of working conditions. The spiral wound bobbin is formed by winding one spiral wound paper layer 100, or may be formed by winding and splicing a plurality of spiral wound paper layers 100. The spiral wrap layer 100 includes a wrap base layer 110, and the wrap base layer 110 is spirally wound. The ribbed structure 120 is disposed on the roll paper substrate 110 and wound in the direction of extension of the roll paper substrate 110 such that the ribbed structure 120 is spirally wound on the roll paper substrate 110. The web-forming structure 120 can be attached to the web substrate 110 in a variety of ways, and can be adhered by an adhesive layer, or in some embodiments, can be integrally formed. The rolled paper substrate 110 may be a rectangular piece of paper when unrolled. When the paper is spirally wound, one long side edge of the paper can be adhered to the other opposite long side edge of the paper through adhesive. Of course, in some embodiments, when the number of the spiral wrap layers 100 is plural, the adjacent spiral wrap layers 100 are adhered by the adhesive. When the spiral wrap layer 100 includes a plurality of roll paper base layers 110, adjacent roll paper base layers 110 may also be bonded by an adhesive. In the forming process of the spiral winding paper tube, the paper tape is wound on the central rotating shaft 700, and the central rotating shaft 700 is driven by the device to rotate at a preset speed, so that the paper tape is in a spiral state.

In this embodiment, by setting the spiral wound roll to be composed of the spiral wound roll 100, the spiral wound roll 100 includes the roll paper base layer 110 disposed spirally and the rib forming structure 120 extending along the roll paper base layer 110, so that the spiral wound roll has the rib forming structure 120, and the rib forming structure 120 is spirally wound on the sidewall of the spiral wound roll. Thus, when the spiral winding paper cylinder is stressed, the winding paper base layer 110 can transfer the load to the rib forming structure 120, the thickness of the rib forming structure 120 is larger than that of the winding paper base layer 110, and the bearing capacity of the rib forming structure is stronger, so that the bearing capacity of the spiral winding paper cylinder is improved, and the strength of the spiral winding paper cylinder is improved; in production application, the thickness of the spiral winding paper tube can be reduced, and then the overall strength of the spiral winding paper tube is ensured by arranging the rib structure 120, so that the production cost is reduced, and the competitiveness is improved.

When the cross section of the stiffener structure 120 is rectangular, the length or width of the rectangle may be the width thereof. The width of the roll paper base layer 110 refers to the width of its unfolded rectangle, and the width of the ribbed structure 120 refers specifically to its dimension in the width direction of the roll paper base layer 110. The ratio of the width of ribbed structure 120 to the width of the spiral wrap of wrap substrate 110 is 1/55-2/5, and the ratio of the width of ribbed structure 120 to the wrap width cannot be too small, which means that ribbed structure 120 occupies less of the wrap width and is difficult to provide sufficient strength reinforcement; the ratio of the two is not too large, and if the ratio is too large, the material quantity is large, which is not favorable for saving materials. The greater the thickness of the web substrate 110, the greater the thickness or height of the ribbed structure 120, resulting in greater load bearing capacity of the ribbed structure 120.
