Abstract

The invention discloses a coiled core pipe with a uniform and rough surface. The coiled core pipe comprises a rotating cylinder, wherein a circular through hole is formed in the inner side of the rotating cylinder; a rotating sleeve is fixedly connected to the circular through hole of the rotating cylinder, and a circular through hole is formed in the outer side of the rotating sleeve; a connecting shaft is fixedly connected to the circular through hole of the rotating sleeve, and the length of the connecting shaft is greater than that of the rotating cylinder; and spraying particles are sprayed on the outer side of the rotating cylinder. According to the coiled core pipe with the uniform and rough surface, by arranging the spraying particles, when a copper aluminum foil is rotated, heading and priming can be well performed on the copper aluminum foil; when the rotating cylinder rotates the copper aluminum foil, the spraying particles are capable of straightening out an uneven surfaceof the copper aluminum foil, so that the phenomenon of wrinkling when the copper aluminum foil is rotated is avoided; and moreover, the spraying particles can be selected according to different thicknesses of the copper aluminum foils, so that friction force between the copper aluminum foil and the rotating cylinder is increased when the copper aluminum foil is rotated.

Description

technical field

[0001] The invention relates to the technical field of core tubes, in particular to a core tube with a uniform and rough surface. Background technique

[0002] Copper-aluminum foil is an essential material used in power batteries. Copper-aluminum foil is an active metal. In dry air, a dense oxide film is formed on the surface of copper-aluminum immediately, so that copper-aluminum will not be further oxidized and can withstand water; but The powder of copper and aluminum is very flammable when mixed with air; molten copper and aluminum can react violently with water; copper and aluminum are amphoteric and are easily soluble in strong alkali and dilute acid. With good ductility, products are often made into rods, flakes, foils, powders, ribbons and filaments. The content of copper and aluminum in the earth's crust is second only to oxygen and silicon, ranking third. The most abundant metal element in . In the development process of the three important indust...
