Negative-pressure adsorption type precise compounding device for reflective layer and PVC (polyvinyl chloride) fabric

Abstract

The utility model discloses a negative pressure adsorption type accurate compounding device for a reflective layer and a PVC (polyvinyl chloride) fabric, and belongs to the technical field of fabric compounding devices. Comprising a base, a negative-pressure die holder fixed to the base through a supporting rod, a negative-pressure housing connected to the bottom of the negative-pressure die holder in a conducting mode and a negative-pressure pump fixed to the base through a support, and the input end of the negative-pressure pump is connected with the negative-pressure housing in a conducting mode. A positioning groove is formed in the lower surface of the negative-pressure mold base, positioning columns fixedly connected with the negative-pressure mold base are symmetrically arranged on the outer side of the positioning groove, a mold pressing base is installed above the negative-pressure mold base, and a containing groove is formed in the lower surface of the mold pressing base. The reflective layer is prevented from getting close to the negative pressure suction port and being distorted and deformed under the action of negative pressure, and the reflective layer and the PVC fabric can be accurately compounded together.
