Efficient heating and mixing device for PVC material injection molding

Abstract

The invention discloses an efficient heating and mixing device for PVC material injection molding. The efficient heating and mixing device comprises a mixing cylinder, a heating main pipe and a heating bin, the top of the heating main pipe is fixedly connected with a converging bin, heating auxiliary pipes are uniformly and fixedly connected to a portion between the converging bin and the bottom of the heating main pipe circumferentially, the heating bin is fixedly connected to the lower surface of a bottom plate of the mixing cylinder, the heating main pipe is covered with the heating bin, evaporate liquid is arranged in the heating bin in a contained mode, and a heating plate is further fixedly connected in the heating bin. Slurry for PVC injection molding is placed in the mixing barrel, then a cover body is closed, sealing is carried out on the mixing barrel through a sealing seat, the evaporated liquor is contained in the heating bin, then the heating plate is started, the evaporated liquor is heated to form steam when the heating plate works, hot steam enters the heating main pipe to heat the slurry, and meanwhile, the hot steam further flows in the heating auxiliary pipes, so that the heating area is effectively increased, the heating effect is further improved, and the device can be conveniently moved and fixed through the arrangement of self-locking universal wheels.

Description

technical field [0001] The invention relates to the technical field of PVC material production, in particular to a high-efficiency heating and mixing device for PVC material injection molding. Background technique [0002] PVC is polyvinyl chloride. It is a polymer material obtained by addition polymerization of vinyl chloride. It is the third most widely produced synthetic plastic polymer after polyethylene and polypropylene. Pure PVC is a white powder with an amorphous structure. , poor stability to light and heat, no fixed melting point, good mechanical properties, excellent dielectric properties. [0003] When preparing boards or components through PVC, it is first necessary to melt pure PVC in a melting furnace, then add various additives to the mixing cylinder to mix and stir with the melted PVC, and then prepare slurry for injection molding. In the prior art, mixing The cylinder generally only has the function of mixing and stirring, but in the process of mixing and ...
