A filter extrusion cutting system for rubber compound

Abstract

The invention relates to the technical field of rubber mixing processing, in particular to a filtering extrusion cutting system for rubber mixing, comprising a lifting device, a tablet pressing device, an extrusion conveying device and a filtering cutting device, wherein the lifting device comprises a lifting roller, the The discharge side of the lifting roller is located above the filtering device, the tablet pressing device is installed between the lifting roller and the feeding port of the extrusion conveying device, and the filtering and cutting device is installed at the discharging port of the extrusion conveying device Position, the lifting roller is used to lift the belt-shaped rubber compound to be filtered to the top of the extrusion conveying device, and the tableting device is used to receive the belt-shaped rubber compound exported by the lifting roller, carry out pre-compression and guide it into the extrusion transmission device. At the feeding port of the device, the belt-shaped rubber compound is introduced into the extrusion conveying device, and then passes through the filter and cutting device to form a plurality of side-by-side strip-shaped rubber compounds, which are then cut.

Description

technical field [0001] The invention relates to the technical field of rubber mixing processing, in particular to a filtering extrusion cutting system for rubber mixing. Background technique [0002] The compounded rubber is made of raw rubber and can be used as a colloid in the adhesive process of fabrics, paper materials, etc. [0003] At present, the compounded rubber is mixed with compounding agent in the block, and the powdered raw rubber is mixed by a rubber mixer. It needs to be filtered before the processing and subsequent use. [0004] The current mixing device includes a vertical cylindrical structure, and a filter screen is installed in the cylindrical structure, and the mixed rubber is pressed down by force to filter through the filter screen. When using the existing device for filtration, since the internal space of the cylindrical structure is limited, only the block-shaped rubber compound can be introduced into the feeding port of the cylindrical structure in...

AI Technical Summary

Problems solved by technology

When using the existing device for filtration, since the internal space of the cylindrical structure is limited, the block-shaped mixed rubber can only be introduced into the feeding port of the cylindrical structure in stages, and a batch is exported every time the pressing is completed. Secondary compound, the process cannot achieve continuous filtration

In addition, since the mixed rubber introduced into the cylindrical structure is blocky, its volume is relatively large and its texture is relatively hard. When each compression is performed, the mixed rubber derived from the filter holes of the filter screen is not uniform enough, and the central position The output volume is the largest, and the output volume around it is small
