The present utility model relates to a material recycling device for a plastic box hollow blow molding machine, comprising a bin. A recycling inlet is arranged on the circumference of the bin, a weighing and discharging device is installed at the bottom of the bin, a discharging cylinder is arranged at the lower end of the weighing and discharging device, a screw connecting seat is arranged at the lower end of the discharging cylinder, and the lower outlet of the screw connecting seat is connected with the inlet of a recycling screw pump. The top of the bin is connected with a vacuum dust removal box, the lower end of which is communicated with the bin, and the top of the vacuum dust removal box is provided with a vacuum suction port connected with a vacuum pipeline through an angle valve. A secondary dust removal cylinder is covered on the outer periphery of the discharging cylinder, the lower port of which is connected with the upper inlet of the screw connecting seat, and a secondary suction port is arranged on the lower circumference of the secondary dust removal cylinder. Dust is sucked into the vacuum pump, making cleaning simple and fast without causing blockage of the dust removal screen and poor suction; weighing errors caused by dust falling are also avoided. Residual dust from recycled material is lifted and extracted from the secondary suction port.
