pvc automatic feeding and mixing system

Abstract

The invention discloses a PVC automatic feeding and stirring system. The device comprises a vertical barrel-shaped calcium powder bin, a calcium powder conveying machine, a PVC powder conveying machine, a roots blower, a cyclone separator, a dust remover, a DOP feeding tank, a stirring kettle with a scale, a storage cylinder and a screw pump, wherein calcium powder of the calcium powder bin is connected to the calcium powder conveying machine through the lower calcium powder conveying pipeline, the calcium powder conveying machine is connected with the roots blower, the calcium powder is fed into the cyclone separator by the roots blower, a PVC material in the PVC powder conveying machine is fed into the cyclone separator by the roots blower, a dust collection pipe is arranged at the top of the cyclone separator and is connected with the dust remover, a hydraulic pump is arranged in the DOP feeding tank, the DOP is fed into a stirring kettle with the scale, the material outlet of the cyclone separator is right opposite to the feeding hole of the stirring kettle with the scale, the stirred PVC mixed material is conveyed to the storage cylinder, and then the PVC mixed material is conveyed to a PVC circulation cylinder of a bottom-covering processing line by the screw pump and used for bottom covering.

Description

technical field [0001] The invention relates to a raw material supply and processing system for block carpet production, in particular to a PVC automatic feeding and stirring system. Background technique [0002] Block carpets are commonly known as "square carpets", also known as assembled carpets. This kind of carpet is easy to transport, easy to install, remove and replace, and is the first choice for office carpets. The structure of the tiled carpet is composed of the carpet surface on the upper surface and the bottom back below, and the carpet surface and the bottom back are bonded together. Among them, the carpet surface is made of tufted blank by tufting non-woven fabric, and then coated with EVA latex on the bottom surface of the tufted blank, and dried to make a tufted pre-coated carpet surface. The backing is usually PVC backing material, which is mainly composed of calcium powder (CaCO3), commonly known as stone powder, polyvinyl chloride (PVC), DINP or DOP oil, ...

AI Technical Summary

Problems solved by technology

This method has slow batching speed, poor measurement accuracy, high labor intensity of workers, large space occupied by raw materials bagged or bulk stacked, low degree of automation of production, large dust in the site environment, and certain damage to the health of workers.

The normal operation of the bottom-covering processing line is often affected by problems such as the PVC compound not being supplied in time
