Technical field
The utility model relates to a kind of parts of rubber mixing machine, particularly a kind of parts of opening rubber mixing machine.
Background technology
At the widely used opening rubber mixing machine of rubber and plastics machine industry, former and later two rollers are rotating relatively with different linear velocity (fixed speed ratio), sizing material is being drawn under the effect of frictional force between two rollers, along with dwindling of two roller gaps, make sizing material be subjected to pushing consumingly and shearing, oxidative cleavage takes place in rubber macromolecule in mechanical chain rupture, thereby increases plasticity, reaches the purpose of refining glue.
The opening rubber mixing machine that uses has frame and rack-mounted motor, deceleration device, a pair of refining rubber roll tube, gear drive and a pair of speed ratio gear at present.One end of back roller is fixed with driven pulley, the other end is fixed with a speed ratio gear; One end of blanket roller is fixed with the another speed ratio gear and is meshed with the speed ratio gear of back on the roller.The power input component of the power output shaft of motor and deceleration device movingly, be fixed with driving gear on the power output shaft of deceleration device, driving wheel is by to being fixed on the driven pulley transferring power of back on the roller, back roller by intermeshing a pair of speed ratio gear to the blanket roller transferring power.And for the mill of enclosed central driving, its motor directly drives forward and backward roller with certain speed ratio revolution by large-scale enclosed gear reduction unit and Hooks coupling universal coupling.This structure has been cancelled driven wheel and speed ratio gear, replaces large-scale enclosed gear reduction unit.
Also have a kind of opening rubber mixing machine (abbreviation rubber breaker) that is specifically designed to brokenly glue slightly different in the prior art with said structure, because broken adhesive process is not really strict to the requirement of speed ratio, speed ratio gear before and after this transmission is arranged and omitted between the roller, speed ratio between the roller of front and back is provided by the frictional force between front and back roller and the sizing material, speed ratio comes and go, and is called free speed ratio.
Aforementioned various transmission arranges that except that rubber breaker the speed ratio before and after all can guaranteeing effectively between the roller is constant, but sizing material or process requirements then can not be adjusted the speed ratio between the roller of front and back when changing easily.For rubber breaker, speed ratio requires not strict though its transmission is arranged, adopted free speed ratio, but this state speed ratio between the roller of front and back is down provided by the frictional force between roller and the sizing material fully, can not accurately be controlled, in case sizing material or process requirements change, can't adjust at all.
Along with the sustainable development of the development of rubber and plastic industry, particularly reclaimed rubber and ground rubber production technology, all kinds of production technologies are constantly tested and are improved, and obtain new breakthrough, make production technology no longer unalterable to the demand of roller speed ratio.These development to rubber and plastics machine particularly opening rubber mixing machine new requirement has been proposed, can't be accurately between the roller of front and back, the fixed speed ratio or the free speed ratio of instant adjustment can not satisfy the production technology demand.
