Description

Technical Field

[0001] The utility model relates to the technical field of curtain fabric production equipment, in particular to a fully automatic fabric taking and splicing device. Background Art

[0002] During the tire production process, a fiber cord layer needs to be set on the tire. It is the skeleton of the pneumatic tire and is made of several layers of plastic cord. These cords are usually made of high-strength, low-elongation, and excellent fatigue-resistant cord materials, such as cotton, rayon, polyamide, polyester, aromatic polyamide or steel wire. It mainly bears most of the load on the tire, including load pressure, internal air pressure and lateral shear force, while protecting the tire rubber from stretching and enhancing the strength and stability of the tire.

[0003] Before welding fiber cords, the distance between the two cords needs to be adjusted by splicing. Currently, cord removal and assembly are mostly done by delivering the cut cords to a splicing workbench via a main conveyor belt. An operator then picks up the cord and splices it with the tail of the previous cord, rolling it with rollers to complete the cord removal and assembly process. This method of operation is inefficient in actual use, and the quality of the joints between the cords is poor, which can easily affect the subsequent cord welding effect. Utility Model Content
