Webbing processing fixed-width unwinding device

Abstract

The invention discloses a webbing processing fixed-width unwinding device which structurally includes a machine frame, an unwinding device body, a webbing, a deflection rectify wheel, a tensioning wheel, a work box and a workbench. The workbench is welded to the top of the machine frame, the work box is installed on the workbench, the tensioning wheel is arranged on the side surface of the work box, and the deflection rectify wheel is arranged on the side surface of the tensioning wheel. The unwinding device body is connected to the side surface of the machine frame and is located below the deflection rectify wheel, and the webbing is wound on the unwinding device body. The unwinding device body includes an unwinding wheel, a shaft bracket, a friction device, rotating shafts, a transmission device and a lifting device. The two sides of the unwinding wheel are correspondingly mounted on the shaft bracket through the rotating shafts, and the shaft bracket is connected to the side surfaceof the machine frame. The webbing processing fixed-width unwinding device has the beneficial effects that through the thickness change during webbing unwinding, the friction of a rubber block with the rotating shafts is gradually increased, the reduction in the weight of the webbing can be offset by the increase in the friction, the pulling force of the unwinding wheel on the webbing remains unchanged, the tension of the webbing can be kept constant by cooperating with constant tensile force, and processing is convenient.

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
