Device for removing folds of cylindrical kraft paper battery through diagonal pressing

Abstract

The invention relates to the field of kraft paper, in particular to a device for removing folds of a cylindrical kraft paper battery through diagonal pressing. The technical problem to be solved by the invention is to provide the device for removing the folds of the cylindrical kraft paper battery through diagonal pressing. According to the technical scheme, the device for removing the folds of the cylindrical kraft paper battery through diagonal pressing comprises a supporting frame, a pressing mechanism, a rotating mechanism, a first limiting plate, a second limiting plate, a connecting plate and the like; a pressing mechanism is arranged in the supporting frame. Kraft paper is pasted on the surface of the cylindrical battery, a glue spraying mode is adopted during pasting, fluff on the surface of the kraft paper faces and makes contact with the surface of the battery more tightly, and air is prevented from entering the kraft paper; meanwhile, the number of wrinkles on the top of the battery after attachment is controlled so as to facilitate treatment, the wrinkles are bent and attached again, so that the wrinkles are not in a vertical state any more to isolate air, and subsequent sealing operation is more convenient after attachment.

Description

technical field [0001] The invention relates to the field of kraft paper, in particular to a device for diagonally pressing and removing kraft paper cylindrical battery folds. Background technique [0002] Kraft paper, used as a packaging material, has high strength and is usually yellowish brown. Semi-bleached or fully bleached kraft pulp is light brown, cream or white. It is flexible and strong, with high burst resistance, and can withstand large tension and pressure without breaking , usually used as cylindrical battery insulation wrapping material; [0003] In the existing kraft paper-wrapped cylindrical battery technology, the kraft paper and the base paper are brushed with self-adhesive kraft paper stickers, and then pasted on the surface of the cylindrical battery. The glue will make the fluff on the surface of the kraft paper face different directions, increase the contact space with the battery surface after lamination, and easily enter the air. At the same time, t...

Problems solved by technology

[0003] In the existing kraft paper-wrapped cylindrical battery technology, the kraft paper and the base paper are brushed with self-adhesive kraft paper stickers, and then pasted on the surface of the cylindrical battery. The glue will make the fluff on the surface of the kraft paper face different directions, increase the contact space with the battery surface after lamination, and easily enter the air. At the same time, there will be many wrinkles on the top of the battery, and the shapes of the wrinkles are different, and even some wrinkles are not tightly bonded. As a result, air enters into the pasted kraft paper sticker, which reduces the viscosity of the whole kraft paper sticker and weakens the insulation of the battery, which greatly affects the quality of the battery and poses a great safety hazard;
