The invention relates to mixing equipment, in particular to hot-melt-adhesive molten ingot mixing equipment for production of a natural gas aluminum-plastic composite tube. According to the hot-melt-adhesive molten ingot mixing equipment for production of the natural gas aluminum-plastic composite tube, the time is saved, the labor intensity is small, and the mixing effect is better. The hot-melt-adhesive molten ingot mixing equipment for production of the natural gas aluminum-plastic composite tube comprises a bottom plate and the like; brackets are vertically mounted on the top of the bottomplate in a left-right symmetrical mode, and a mixing frame is mounted on the top, close to the right, of the bottom plate; and the upper portion of the mixing frame is arranged to be open, an up-downmoving device is arranged in the middle of the left side face of the bracket on the right portion, a mixing device is arranged on a moving part of the up-down moving device, and a mixing part of themixing device is located in the mixing frame. According to the hot-melt-adhesive molten ingot mixing equipment for production of the natural gas aluminum-plastic composite tube, hot melt adhesive in the mixing frame is mixed through the mixing device, so that the effects that the time is saved, the labor intensity is small, and the mixing effect is better are achieved.
