Cooling paper tube with spiral filling structure as well as preparation method and application of cooling paper tube

Abstract

The invention discloses a cooling paper tube with a spiral filling structure as well as a preparation method and application of the cooling paper tube, relates to the technical field of paper product processing, and aims to provide a universal paper tube product which has multiple diameters and multiple lengths, has certain supporting strength and must have a better cooling effect. The paper tube comprises a tube wall and a content mechanism; the pipe wall is a spiral pipe wall or a seamless pipe wall; the content mechanism is a spiral blade, the outer side edge of the spiral blade is fixed on the inner surface of the pipe wall and extends along the axis of the pipe wall at equal intervals in the axial direction, and the axial size of the spiral blade is equal to the length of the pipe wall; the spiral blade is arranged in the paper tube, so that the circulation path of gas or liquid in the paper tube is changed, the retention time of the gas or liquid in the paper tube is prolonged, and the gas or liquid in the tube is cooled; as a general product, the paper tube is wide in application field, simple in structure, easy to process, low in production cost and suitable for batch production and processing.

Description

technical field [0001] The invention relates to the technical field of paper product processing, in particular to a general-purpose cooling paper tube and its preparation and application. Background technique [0002] Paper tubes are tubular objects processed from paper. There are many types and auxiliary materials. In production and life, paper tubes have a wide range of uses. [0003] Some paper tubes are used as structural support components, such as high-strength paper tubes and small-wall thick paper tubes. Among them, high-strength paper tubes have high compressive strength and stable surface gaps, and are widely used in large-scale winding industries such as papermaking and film. Its outstanding advantages It is suitable for high-speed, large-capacity winding, and has high cost performance; while the small-wall paper tube has thin wall thickness, flat end surface, and accurate length, which is suitable for adhesive tape, plastic wrap, medical and other industries.

Problems solved by technology

[0004] However, some paper tubes tend to be used directly as products, such as paper tubes for drinking straws and cigarette smoking products. Among them, the main consideration for drinking straws is that the paper tubes are environmentally friendly and degradable. For hot drinks, the disadvantages of paper straws are reflected. First, the strength of its standard weight or volume material cannot be compared with that of existing plastic straws. Therefore, the thickness of the straw is relatively large, which causes the beverage with higher temperature to move in the tube. The degree of heat dissipation in the process is very low, and the use effect is not good; while the paper tubes used in cigarettes and smoking products are more concerned with the characteristics of low cost, light weight, and no release of harmful substances under the heating of high-temperature smoke. It mainly relies on the filter rod tow contained in the paper tube, the cooling foil and various uneven structures on the inner wall of the paper tube to slow down the gas flow rate and increase the time for heat dissipation, such as "a A support unit containing folds and protrusions and a cigarette containing it 202010477487.8", but these technical solutions often cause the internal structure of the paper tube to be complicated and the cost is high

[0005] Considering the above problems, at present, in the field of daily consumer goods that require relatively low structural strength, there is still a lack of a general-purpose multi-diameter, multi-length, and certain support strength. The most important thing is that it must have better cooling. Effect paper tube products
