A kind of anti-tire base is scraped the disconnected thick device of modified bituminous pitch coiled material moulding control
Technical field
The present invention relates to a kind of manufacturing equipment of modified bituminous pitch coiled material, specifically, relate to a kind of anti-tire base and scrape the disconnected thick device of modified bituminous pitch coiled material moulding control.
Background technology
At present, the waterproof roll of selling in China market mainly contains three major types, that is: 1. modified asphalt waterproof coiled materials; 2. high molecule plastic sheet material; 3. rubber water-proofing coiled.Wherein, modified asphalt waterproof coiled material accounts for the leading position in application, and 2010 annual productions reach 400,000,000 square metres, and wherein self-adhesive coiled material accounts for 30%, and every year with 50% speed increment, other common hot melt coiled material accounts for more than 60%, every year with the speed increment of 15% left and right.The construction method of these coiled materials in general application project work progress has again three kinds, that is: after 1. use benzine blow lamp heating and melting pitches, paste in basic unit, as: modified asphalt waterproof coiled material; 2. with cold binding agent brushing, on base, paste, as: high molecule plastic sheet material and rubber coiled material; 3. with the self-adhesion of coiled material itself, paste in basic unit, as: self-adhesive modified asphalt waterproof rolling material, with high molecule plastic sheet material and the rubber coiled material of self-adhesive layer.
Need to be on tire base cloth in the production process of modified bituminous pitch coiled material the dip-coating modified pitch material of coating, at this moment just adopt dip-coating process equipment.This equipment generally comprises material pond 1, material is provided with several in order to the compregnate roller 2 of lifting tire base cloth in pond 1, compregnate roller 2 is connected with elevating mechanism 3, the top in material pond 1 is provided with a plurality of guide rollers 4, one end of tire base cloth 5 is passed through guide roller 4, compregnate roller 2 successively ... after guide roller 4, after thick via thick device 6 tune of moulding control, leave material pond and enter next process.
The thick device of moulding control comprises two doctor rolls that are oppositely arranged up and down, and conventional upper doctor roll and lower doctor roll are round roller shape, and its shortcoming is to cause with both sides variable thickness in the middle of the coiled material of moulding, often occur thick middle positive bracket type "
()" or the thick anti-bracket type in intermediate thin both sides "
) (" defect, and in the material of easily coating, impurity, particle, lump enrichment are blocked between two round rollers, cause the disconnected phenomenon of tire base cloth card.
Summary of the invention
The technical problem that will solve required for the present invention is to provide a kind of anti-tire base and scrapes the disconnected thick device of modified bituminous pitch coiled material moulding control.
For realizing above-mentioned purpose of the present invention, technical scheme of the present invention is as follows: a kind of anti-tire base is scraped the disconnected thick device of modified bituminous pitch coiled material moulding control, described one-tenth type controller comprises two thick devices of the tune being oppositely arranged up and down, it is characterized in that these two are adjusted thick device to be wedge structure, adjust the front end of thick device to be oppositely arranged for these two, between the front end of these two the thick devices of tune, be provided with the first gap, this first gap is the input of the thick device of this moulding control, between these two Tiao Houqi rear ends, be provided with the second gap, this second gap is the output of the thick device of this moulding control, the first gap is less than the second gap.At least one in described two thick devices of tune is provided with slack adjuster, adjustable upper and lower two gaps of adjusting between thick devices.
When scribbling described two gaps of adjusting between thick devices of tire base cloth process of the material of coating; because the thick device of described tune is wedge structure; and between two thick devices of tune, the gap of rear end is greater than the gap of front end; therefore can realize the effect of the unnecessary material automatic shunt of coating on tire base cloth; therefore avoided unnecessary coat material, particularly impurity, particle or lump to be blocked in into the input of type controller; the phenomenon that generation is haled, has prevented that tire base cloth from being scraped disconnected.And due to its wedge structure, also make with on coat material after have tire coiled material more smooth, thickness is more even.Described doctor roll can be made with engineering ceramics, and heat-resistant antifriction performance is better.Therefore, the invention has the advantages that and can prevent that tire base cloth from scraping disconnectedly, and have tire coiled material more smooth after coating, thickness is more even.

The specific embodiment
A kind of anti-tire base is scraped the disconnected thick device of modified bituminous pitch coiled material moulding control, the thick device 6 of described moulding control comprises two thick devices of the tune being oppositely arranged up and down, it is characterized in that these two are adjusted thick device to be wedge structure, and the front end of the thick device of tune of these two wedge structures is oppositely arranged, between the front end of these two the thick devices of tune, be provided with the first gap 7, this first gap 7 is the input of the thick device of this moulding control, between these two Tiao Houqi rear ends, be provided with the second gap 8, this the second gap 8 is the output of the thick device of this moulding control, and the first gap 7 is less than the second gap 8.According to a particular embodiment of the invention, the front end of the thick device of tune of described wedge structure is the sharp angle α of 50 ~ 70 degree.At least one in described two thick devices of tune is provided with slack adjuster, adjustable upper and lower two gaps of adjusting between thick devices.According to a particular embodiment of the invention, when the first gap is 0mm, the second gap is 100 ~ 150mm; Raise thick device and be provided with slack adjuster, when the thick device of rise moves up and down, the equidistant movement simultaneously of the first gap and the second gap; When having tire base joint to pass through, also can regulate and raise thick device, the first gap is increased rapidly, the second gap is corresponding to be reduced, and allows thicker joint area without barrier by the thick device of control.In general, two are adjusted the first gap between thick device front end is 0 ~ 100mm, and the second gap between two doctor roll rear ends is 100 ~ 250mm.
The thick device of described tune can be made with engineering ceramics, and heat-resistant antifriction performance is better.In this manual, the tip of described wedge structure is called front end, other end Ze Wei rear end.
