Description

Technical Field

[0001] The present invention relates to the technical field of seamless paper tube production, and in particular to a seamless paper tube machine and a seamless paper tube production process. Background Art

[0002] In the paper tube manufacturing industry, the manufacture of seamless paper tubes has always been an important link. Traditional seamless paper tube machines usually have problems such as complex structure, cumbersome operation, low production efficiency and unstable product quality. In order to overcome these shortcomings, the industry has been exploring more advanced and efficient seamless paper tube manufacturing technology.

[0003] Most of the common seamless paper tube machines on the market currently use a single drive mode and lack effective adjustment of the tension of the paper belt, which makes the paper tube easy to loosen or break during the production process. In addition, the traditional gluing method is usually through manual brushing or simple mechanical spraying. This gluing method is not only inefficient, but also difficult to control the amount of gluing, which easily affects the strength and sealing of the paper tube.

[0004] During the winding and forming process of paper tubes, the performance of the pusher and presser components is also crucial. Traditional pushers usually use a simple mechanical push method, which lacks effective control over the winding accuracy of the paper tape. At the same time, the design of the presser component is often not reasonable enough, resulting in uneven pressure on the paper tube during the forming process, which in turn affects the appearance and quality of the paper tube.
