The invention relates to a roller cloth guide-unfolding device, in particular to an anti-loose roller cloth guide-unfolding stacking device. The anti-loose roller cloth guide-unfolding stacking devicecomprises an anti-loose cloth guide component, an upper sliding rack component, supporting plates, a lower sliding rack component, a cloth guide-unfolding mechanism, a cloth rolling flattening mechanism and a cloth laying platform component, the anti-loose cloth guide component is connected to the upper end of the cloth guide-unfolding mechanism, two sides of the bottom end of the upper sliding rack component are each fixedly connected with one of the supporting plates, the bottom ends of the two supporting plates are fixedly connected to two sides of the top end of the cloth laying platformcomponent, the lower sliding rack component is fixedly connected to the front side of the bottom end of the upper sliding rack component, the upper end of the front side of the cloth guide-unfolding mechanism is slidably connected to the front end of the upper sliding rack component in a matched manner, and the upper end of the rear side of the cloth guide-unfolding mechanism is slidably connectedto the rear end of the upper sliding rack component in a matched manner. By means of the anti-loose roller cloth guide-unfolding stacking device, cloth guide-unfolding, cloth conveying, cloth stacking and stacked cloth rolling and flattening can be synchronously realized, and the cloth guide-unfolding efficiency can be effectively improved.
