Description

Composite double-layer linear hollow paper tube manufacturing device

Technical Field

The invention relates to the technical field of devices requiring paper tubes such as beverage paper straws or cigarettes which are not combusted by heating, in particular to a device and a method for manufacturing a composite double-layer linear hollow paper tube.

Background

At present, the known paper drinking straw for drinks and paper tube for heating non-combustible cigarettes are generally manufactured by adopting a radial spiral winding method. A plurality of paper tapes with glue are continuously warped on a fixed steel shaft at a certain angle by a flat belt, the paper tapes are warped into continuous spiral paper tubes in a spiral shape, and then the paper tubes with the required length are synchronously cut by a plurality of circular knife reciprocating cutting devices.

The existing radial spirally wound paper tube has the following defects due to the forming principle:

first, the speed is slow: the spiral is slower than the straight line and the winding resistance is large, so that the high-speed production cannot be realized. In addition, the formed spiral paper tube only can be synchronously cut by adopting a plurality of circular knife reciprocating cutting devices due to the influence of the bending angle and the tightness on the stability of the output speed, and the plurality of circular knife reciprocating cutting devices have large motion inertia, so that the speed is further limited.

Secondly, the usage amount of materials and adhesive glue is large: in order to ensure the strength of the paper tube, the spiral paper tube generally adopts multiple layers of thickened paper tapes, and the material consumption is large. The output speed of the spiral paper tube is unstable, and the lengths of the spiral paper tubes cut by the circular knife reciprocating cutting devices are consistent, so that one section of redundant spiral paper tube is wasted when the spiral paper tube is cut once. Because the paper tape is spirally wound, the whole surface of the paper tape is glued to ensure that the edge of the paper tape is not turned over, and the used adhesive glue is more.

Thirdly, the device is complex and has poor stability: the reciprocating cutting device with the plurality of circular knives has large volume and weight, complex device and large motion inertia. When spirally winding, the paper tape glued by the flat belt is warped into the surface of the steel shaft, the half warp of the warping angle of the flat belt is very small, so that the service life is short, the linear velocity is uneven, and the stability is poor.

Fourth, food safety is poor, paper tube quality is poor: the glue of the spiral paper tube is nontoxic, but has certain influence on human bodies due to large contact. And the middle paper tape needs to be glued on two sides during spiral bending, the using amount of glue is large, and part of glue overflows from the edge of the paper tape, so that a large amount of glue is remained on the inner surface and the outer surface of the spiral paper tube, and the food safety is poor. In addition, the surface is rough, the thickness is not uniform and the quality of the paper tube is poor due to spiral forming.
