The invention discloses an unreeling machine and a method for controlling unreeling of flexible materials, and belongs to the technical field of material processing. The unreeling machine comprises a material roller, a conveying roller, a motor, a controller, a first distance measuring unit and a second distance measuring unit. The material roller is driven by the motor, the first distance measuring unit is arranged below the position between the conveying roller and the material roller, the second distance measuring is arranged on the outer side of the material roller and aligned with the outer cylindrical surface of the material roller, and the controller is respectively connected with the first distance measuring unit and the second distance measuring unit and controls the rotation speed of the motor. According to the unreeling machine, the conveying roller is adopted to convey the flexible materials so that tension of the flexible materials is close to zero, the unreeling speed of the material roller is controlled through monitoring the radius of the material roller and position changes of a flexible material overhanging section, tension fluctuation hardly exists in the process of unreeling the flexible materials, and therefore the 'micro-tension' or 'zero-tension' unreeling of the flexible materials can be completed with high quality.
Description
technical field [0001] The invention relates to the technical field of material processing, in particular to an unwinding machine and a method for controlling unwinding of flexible materials. Background technique [0002] Unwinding machine is a kind of high-efficiency equipment in the field of flexible material processing. At present, the existing unwinding machine mainly includes tension measuring roller, material roller and controller. Tension measuring roller is an important part to control the tension of flexible materials. Tension The measuring roller sends a signal to the controller according to the magnitude and change of the tension it receives, and the controller controls the motor speed to adjust the speed of the material roller unwinding the flexible material, so that the tension of the flexible material is a constant value when unwinding. [0003] In actual situations, when unwinding material with "slight tension" or "zero tension" is required, the friction force...
