Spreading knife is the very important parts of primary and secondary mixing process in low-temperature primary method, can better bag roller glue is separated with roller in time during production, guarantee the integrality of rubber compounding.
The mill of being furnished with spreading knife can be thoroughly separated from roller by bag roller glue when producing, and guarantees that sizing material completes whole mixing process.If any the broken glue of part, can the broken glue producing when car sizing material be returned in this train number by opening time, the action of spreading knife is set, thereby reduce the fluctuation of sizing material, improve the qualification rate of sizing material.
The use of spreading knife, for supplementing mixing having laid a good foundation, has not only greatly improved production efficiency and sizing material qualification rate, and has reduced the generation of abnormal sizing material, for producers have saved unnecessary labour.
Aborning, the different qualities that can embody according to various sizing materials, does further adjustment and programme-control to spreading knife.On the original basis of low-temperature primary method, to choose optimum position point spreading knife is positioned, the selected of position will be determined the impact of sizing material according to the situation of sizing material bag roller when producing, the height of Various Seasonal roller temperature.Because roller length is longer, must guarantee spreading knife in use cutter hub can not be out of shape, final solution changes binary cutter into by monomer cutter, double-pole is compound and processed by special substance.
Sizing material roughly has following several process when entering mill to final plastic emitting: premix-material feeding-dispersion-mixing, the breakdown action not waiting according to the corresponding spreading knife of each stage material feeding situation time of doing respectively, in time will exist the broken glue of part on spreading knife to return in car, guarantee not lose when the various auxiliary agent rubber master batch of car sizing material, greatly reduce the fluctuation of sizing material rheology simultaneously, promoted the stability of mix quality.
Because the sizing material stress of producing differs, the coefficient of expansion of roller differs, and therefore the gap of spreading knife is provided with to very large difficulty, for corresponding problem, when producing, glue number is divided, and then equipment is finely tuned, and better meets the needs of production.But also need regularly spreading knife spacing to be safeguarded, when long-term production ebonite is more, to safeguard whole cutter hub, make this cutter constantly there is good toughness.
The present invention further carries out separation to roll banding glue again on the basis of spreading knife, better guaranteed the stability of sizing material in mixing process, mainly solved multiple bag roller material roll banding phenomenon, both substituted that conventional production lines is pure manually turns over glue, clot operation, avoid again the phenomenon of various sizing material roll banding in low-temperature primary method, in low-temperature primary method is mixing, played vital effect.
Repeatedly observation through on producing, obtains discussing result after equipment existing capability is analyzed: need to increase a pressure roller that can rotate.Pass through again a large amount of experimental observations, peel off the most at last pressure roller and be positioned at the spreading knife back lower place, object is when sizing material will wrap roller completely, peeling off pressure roller can separate by gravity and turning handle bag roller glue film from roller, whole mixing process is completed smoothly under the condition that does not need extraneous factor.Peel off pressure roller and play a key effect in special roll banding sizing material and each glue mixing process, for various production of once-through method is laid a good foundation.
Peel off pressure roller and be the vitals that is fixed on spreading knife below after mill, mainly play the effect of separated bag roller glue, especially when producing bonding glue material, effect is greatly remarkable.Peeling off pressure roller is the further improvement of carrying out on the basis of spreading knife, spreading knife can carry out separation by the bag roller glue of most situations, but for the special glue of part number and bonding glue material, also there is certain difficulty in separation completely, peels off the generation of pressure roller and broken the deadlock that low-temperature primary method is produced bonding glue material.
In the present embodiment, pressure roller gross weight is 136KG, according to the large I of the power of pullling of sizing material, fluctuates, and sizing material is had to certain shock-absorbing capacity.The selected of pressure roller weight is to determine according to the weight of per car elastomeric compound, and calculates and put into practice tracking by theory, and final design goes out optimum position and weight and the velocity of rotation of pressure roller.
The present invention is for mixing novel auxiliary equipment, from technique, can better meet mixing process, makes finished composition have better dispersion effect and uniformity, has greatly improved the qualification rate of sizing material.From equipment, equipment is simple, generally do not need it to safeguard, long service life, to the point on miscellaneous equipment without conflict, without staggered phenomenon, without any destructiveness.Economically, economic and practical, invest littlely, material is common former steel.Concerning enterprise, under minimum investment situation, can complete higher production efficiency.
The cutter hub of spreading knife of the present invention is made by special material, on the basis of original mill, according to repeatedly repeatedly the experiment of different sizing materials and theoretical reference value being studied, at blanket roller, rear roller, respectively chooses the best gold point of spreading knife.This spreading knife blade is composited by the special blade of bilayer, and bag roller glue is had to better separating effect and not yielding, has greatly improved the diversity of the production efficiency of once-through method and glue number.The needs spy of spreading knife when producing increases Indivudual cylinder separately, and spreading knife is carried out to free open and close action.
In the present embodiment, peel off pressure roller by smooth bar be made, diameter is about the cylindrical roller of 15 centimeters, two ends, with rolling bearing, are fixed in support two ends, the sizing material after roller compressing tablet passes through from peeling off pressure roller.The bonding force of different glue that sizing material is produced varies in size, can drive in various degree peel off the transmission of pressure roller and upper and lower floating, uncontrollable phenomenon while fundamentally having solved sizing material bag roller, effectively reduce sizing material unnecessary platform phenomenon of stopping in mixing process, improved the qualification rate of sizing material simultaneously.
Below to use the present invention to carry out mixing and contrast experiment conventional machines:
1, take the wear-resisting glue in rim of the mouth is example, as follows to having spreading knife and being corresponding contrast experiment without the machine of spreading knife from mixing time, sizing material assay respectively with equipment with board:
1) test from the mill mixing time of the wear-resisting glue in rim of the mouth:
When mixing, mixing to 300-400(s without spreading knife mill) time there is roller phenomenon after bag, manual handle after stopping, about 60(s of processing time) left and right, mixing to 500-600(s) time there is roller phenomenon after bag equally., often there is bag preliminary roller phenomenon or roller phenomenon after bag again in fast due to glue Wen Liang in each processing procedure, frequently also there will be ripe glue phenomenon while just starting to start.Take 20 cars as benchmark, and per car is because of 3-4 minutes about used times of abnormal problem such as pack processing rollers, consuming time altogether: 1-1.3 hours
There is spreading knife mill when mixing, per car mixing to 300(s) there is bag roller trend equally during left and right, but bag during to spreading knife most applications can allow spreading knife separate, effectively avoided artificial parking processing, and reduced the generation of abnormal conditions, thereby improved production efficiency.In production, sometimes also there will be mill banding, but the probability occurring is lower.The average per car processing time was less than 1 minute, consuming time altogether: to be less than 20 minutes.
2) sizing material assay:
The finished composition of producing without spreading knife mill, rheology MH fluctuation is larger, and float value is about 1.5-2, and viscosity number fluctuation range reaches 5 values, and T30, T60, incipient scorch also have obvious difference, therefore sizing material quality are had a great impact.
The finished composition that has spreading knife mill to produce, rheology MH fluctuation is less, and float value is in 0.5 left and right, and viscosity number fluctuation range is 2 values, and T30, T60, incipient scorch significantly do not change.
2, adopt respectively without peeling off pressure roller and have spreading knife and peel off pressure roller and have two kinds of modes of spreading knife, the experiment contrast to secondary mill in mixing process is as follows:
1) without peeling off pressure roller, there is spreading knife test:
Adopt this kind of mode first to take tyre surface as example, mixing cycle is normal, do not find obvious mill banding, to fill glue and the harder sizing material of sizing material, test contrast, produce and substantially can pass through, the phenomenon that is found once in a while bag roller or bores spreading knife, but encapsulate can be pulled off and maintain normal production by pullling in most cases of upper belt.Finally take bonding glue material as example, and this kind of scheme found sizing material bag roller mixing to general in the situation that, and the processing of need manually stopping, and not only delays output, affects the quality of sizing material, also likely causes the generation of the ripe glue phenomenon of sizing material.
2) peel off pressure roller and have spreading knife:
Take respectively above several method to contrast, first two situation can better be met.When carrying out bonding glue material experiment, given full play to the peculiar effect of peeling off pressure roller.Sizing material is under the effect of peeling off pressure roller, can effectively guarantee that the rotation direction of roller glue is consistent with belt direction of travel, but also effectively controlled height and the tensile stress of crossing roller glue, and add the epithelium band speed of service effectively, can complete thoroughly the whole mixing process of bonding glue material.
