Seamless paper tube forming device

Abstract

This invention provides a seamless paper tube forming device, belonging to the field of seamless paper tube technology. The device includes a base and a feeding rack. The feeding rack is fixedly installed on the surface of the base. A gluing mechanism is installed on the surface of the base, comprising a glue tank and a first scraper. The glue tank is installed on the base surface, and a gluing roller is rotatably mounted on the surface of the glue tank. The lower surface of the gluing roller is immersed in the glue in the glue tank. The first scraper is slidably installed inside the glue tank to scrape off the glue on the surface of the gluing roller. This invention, by setting up a gluing mechanism, allows the gluing roller to rotate and apply glue to the paper surface. The first scraper removes the glue from the surface of the gluing roller, preventing excessive glue adhesion that could cause an unsightly paper tube and increasing the drying time, thus helping to ensure the quality of subsequent paper tube forming.

Description

Technical Field

[0001] This utility model relates to the field of seamless paper tube technology, and more specifically, to a seamless paper tube forming device. Background Technology

[0002] Seamless paper tubes are made by weaving multiple layers of paper through a specific process. Compared with traditional paper tubes, seamless paper tubes do not leave seams during the forming process, thus providing better mechanical strength and higher stability. Their structure usually consists of an outer paperboard, an inner paperboard, and an intermediate glue layer. Through the weaving of multiple layers of paper, a high-strength tubular body is formed. They are widely used in textile rolls, electronic product packaging, printed materials, food packaging, and many other fields. In order to ensure the stability and strength of the paper tube, the contact points of the paper need to be properly bonded.

[0003] Therefore, during the seamless paper tube forming process, glue needs to be sprayed onto the paper surface. Existing seamless paper tube forming devices use glue-coating rollers to apply glue to the paper surface, which makes it difficult to control the amount of glue applied, thus affecting the quality of paper tube forming. Utility Model Content
