Description
Technical field
The present invention relates to a kind of production method of cold feed wide rubber sheet extrusion calendaring linkage production line compound belt blank, especially a kind of technological process of cold feed wide rubber sheet extrusion calendaring linkage production line compound belt blank of IW steel curtain mesh tape processing.
Background technology
IW steel curtain net is the unique steel cord mesh grid that is specifically designed to the high-performance adhesive tape by a kind of warp-wise pass-through type cord of particular design and the high extension of broadwise cord through special process, this special braiding structure can make the warp-wise cord not yielding in any case, thereby make steel wire can bring into play its highest intensity and not fragile, have preeminent performance aspect shock resistance, high temperature resistant, tear-proof, the resistance to deformation, having very large groove forming character and be applicable to excellent serviceability than the head roll of minor diameter.The IW steel curtain mesh tape in the mine of many developed countries, industry such as stone pit, colliery, harbour, steel sintering factory, coke-oven plant, cement plant is applied gradually, and the moderate strength scope (trend of 350～2000N/mm) steel cable belts that replaces is arranged.
" the scientific and technical innovation that glue tube belt branch of Chinese rubber TIA delivers in 2008 annual annual meetings, lead technical progress of industry " " structure of IW steel curtain net and performance characteristics and the application in conveyer belt thereof " literary composition of " IW steel curtain net is in application on the conveyer belt and processing technology " and " rubber industry " 2008 the 55th the tenth second phases of volume in the collection of thesis, promotion IW steel curtain net utilizes calender to obtain the technological method for processing of adhesive tape made-up belt through repeatedly fitting.Technological process is: IW steel curtain net → calendering → applying core glue → applying rubber cover → made-up belt.Made-up belt is finished on calender.This technological method for processing mainly exists following limitation and deficiency:
1. the width of adhesive tape is subjected to the size restrictions of calender work roller.
2. the apparatus for production line layout of traditional fabric core adhesive tape and locus relative fixed concerning general enterprise, though capital equipment does not need extra investment,, locus restriction leads out and needs transformation such as devices for taking-up has certain difficulty because unreeling the calendering of IW steel curtain net.
3. binding efficiency and thickness are difficult to control when rolling.Calendar rolls apart from the setting of film thickness be a parameter, when framework material entered between rolling mill roller kiss-coating or fits, roll spacing and film thickness changed immediately.Make in bonding of two layer sizings and the infiltration cord and must exert pressure to two work rollers, this needs the certain hour process to carry out the dancer rools distance.Pressure size between two rollers directly influences roll spacing and film thickness changes, and has influenced the binding efficiency of framework material and the uniformity of made-up belt thickness thereupon.If change of lap, glue kind, specification must frequently be adjusted repeatedly.Be difficult to again correct and rejecting to the sizing material of having fitted up is undesirable, influence the adhesive tape quality.
4. when calendering was fitted, because the effect of horizontal pressure makes double-working tube generation amount of deflection strain, the goods cross section produced thick middle, the thin swelling-waist shape in both sides.Through repeatedly calendering applying back and forth, the cross section interior thickness of goods and the accumulation of both sides thickness difference increase.The pressure that roller produces the middle part of framework material and the extruding of sizing material increase with shearing gradually, add that again tension force was unsuitable excessive when steel curtain net unreeled, and force longitudinally that the spacing of steel cord changes, and also are difficult to keep the straight Founder of broadwise cord.
Summary of the invention
