Description

Technical Field

[0001] The utility model belongs to the technical field of cloth processing, and in particular relates to a cloth loosening machine. Background Art

[0002] During the production and processing of fabrics, it is often necessary to move and transport the fabrics. In order to facilitate the handling of the fabrics, the fabrics are generally rolled into cylindrical rolls. During the handling process, the fabric rolls are often squeezed, bent, wrinkled, etc., which deteriorates the quality of the fabric. Therefore, when using the fabrics in the fabric rolls, it is necessary to loosen the fabrics first.

[0003] A document with a search announcement number (CN209306619U) discloses a new type of cloth loosening machine, including a frame, a rotatable cloth pressing roller arranged on the frame and a cloth placing platform built on the bottom of the frame, wherein a plurality of rotating rollers are arranged on the frame below the cloth pressing roller, and a rubber strip spirally wound around the rotating roller along the axial direction is arranged on the outer surface of the rotating roller, and a swing plate that can swing back and forth is arranged on the frame below the rotating roller, and the swing plate is composed of two electrostatic plates, and the two electrostatic plates are connected by two opposite connecting rods, and the connecting rods are swingably arranged on the frame, and a cloth channel is formed between the two electrostatic plates, and the side of the cloth channel is V-shaped.

[0004] The outer surface of the rotating roller of the above-mentioned device is provided with a rubber strip which is spirally wound around the rotating roller along the axial direction. When the rubber strip rotates, it exerts a lateral force on the cloth so that the cloth can be unfolded laterally. The cloth is fluffy during the unfolding process. If the cloth is too fluffy and the center of gravity shifts when it is piled to a certain height, it may cause the cloth to be scattered, so the staff needs to manually organize it.

[0005] In view of this, the present utility model is proposed. Utility Model Content
