A Ribbon Processing Fixed Width Unwinding Device

Abstract

The invention discloses a fixed-width unwinding device for webbing processing. The structure includes a frame, an unwinding device, a webbing, a deviation correction wheel, a tensioning wheel, a work box, and a workbench. A workbench is welded on the top of the frame. A working box is installed, and the side of the working box is provided with a tensioning wheel, and the side of the tensioning wheel is provided with a rectifying wheel. The unwinding device is connected to the side of the frame and is located under the rectifying wheel. Reel, shaft support, friction device, rotating shaft, transmission device, lifting device, both sides of the unwinding wheel are respectively installed on the shaft support through the rotating shaft, and the shaft support is connected to the side of the frame. The thickness change of the roll makes the friction between the rubber block and the rotating shaft gradually increase, and the reduction of the weight of the webbing is offset by the increase of the friction, so that the pulling force of the unwinding wheel on the webbing remains unchanged, and the constant tension can make the webbing The tension remains constant for easy processing.

Description

technical field [0001] The invention relates to the field of ribbon processing equipment, in particular to a fixed-width unwinding device for ribbon processing. Background technique [0002] After the preliminary weaving and forming of the webbing products, subsequent operations such as gluing, printing, and cutting are required. In the subsequent processing steps of the webbing products, it is necessary to unwind and feed the semi-finished webbing products that have completed the preliminary processing, so as to facilitate fixed-length cutting. jobs, and printing jobs such as hot stamping or pad printing. [0003] When the current fixed-width unwinding device for webbing processing is unwinding, as the webbing becomes less and less, the weight on the unwinding wheel is also reduced, so the tension on the webbing during the continuous unwinding process is uneven. The strength of the tightening device remains constant, and the webbing will loosen as it decreases, and the web...

[0003] When the current fixed-width unwinding device for webbing processing is unwinding, as the webbing becomes less and less, the weight on the unwinding wheel is also reduced, so the tension on the webbing during the continuous unwinding process is uneven. The strength of the tightening device remains the same, the webbing will loosen as it decreases, and the webbing cannot maintain a constant tension
