Description

Technical Field

[0001] The invention relates to the field of artificial leather, in particular to an active unwinding device for producing artificial leather. Background Art

[0002] Artificial leather is made of foamed or laminated PVC and PU with various formulations on a textile or non-woven base. It can be processed according to different strength, color, gloss, pattern and other requirements. It has the characteristics of a wide variety of patterns, good waterproof performance, neat edges, high utilization rate and relatively low price compared to genuine leather. However, the feel and elasticity of most artificial leathers cannot reach the effect of genuine leather. Its longitudinal section shows tiny air bubbles, cloth base or surface film and dry artificial fibers. In the current artificial leather production, specific processing requirements must be achieved through a rewinding device.

[0003] The existing technology has the following problems: when the material of the old unwinding seat is unwinding, the traction force of the previous single machine is transmitted to the material roll through the material body, and then the material roll rotates to achieve the purpose of unwinding. In order to control the tension during the unwinding process, the unwinding chuck adopts a certain counter-tension to make the tension of the leather material more stable during the rotation of the coil. However, it is precisely because of the use of counter-tension that the leather material will shrink in a wide width under the action of traction and counter-tension, thereby affecting the production process and quality requirements.
