Description

The automatic deviation-rectifying system on the throne of a kind of material carrying belt of vacuum belt type drying machine
Technical field
The present invention relates to a kind of material carrying belt of vacuum belt type drying machine deviation-rectifying system on the throne, relate in particular to a kind of automatic deviation-rectifying system on the throne of material carrying belt of vacuum belt type drying machine that adopts Computerized Information Processing Tech.
Background technology
The material containing conveyer belt of vacuum belt drier is have one or more layers Teflon to interweave a kind of connecting gear that band makes passes through the material of carrying by each heating region of drying machine one by one with even velocity.Owing to relate to temperature, vacuum, humidity, conveyer belt length and the material factors such as weightlessness variation in dry run; so; conveyer belt the problem of the normal travel track of skew occurs through regular meeting in working order, thereby influence the continuous operation of drying machine, even makes the conveyer belt damage.
Mechanical deflection correcting form in the past generally is by respectively installing one group of spring on the transmission rolling shaft (driving shaft and driven axle) at the two ends of conveyer belt, utilizes the reverse tension of spring that transmission rolling shaft is kept vertical with running orbit of the tension of conveyer belt.But effect is unsatisfactory in the middle of practice, and main problem is: 1, need be relatively poor by manually carrying out stage adjusting and accuracy; 2, because the tension force of spring when being subjected to the length that is limited in the material containing conveyer belt of material to surpass 10 meters, because of the frictional force between conveyer belt and the heated plate increases, can cause spring inhomogeneous to the pulling force of power transmission shaft, making power transmission shaft produce to skid influences at the uniform velocity advancing of conveyer belt; 3, because spring is a kind of unidirectional pulling force, lack free adjustment, so in case after the scope of the deviant overshoot of conveyer belt, whole deviation-correcting function is just entirely ineffective to the translation of power transmission shaft.
Summary of the invention
Technical problem to be solved by this invention provides the automatic deviation-rectifying system on the throne of a kind of material carrying belt of vacuum belt type drying machine, this system adopts Computerized Information Processing Tech, can be under the state of long-term continuous operation to the material containing conveyer belt of drying machine, realize instant automatic deviation correction on the throne, make the material containing conveyer belt keep straightaway all the time, avoid causing outage or conveyer belt impaired because of skew.
For solving technical problem to be solved by this invention, the automatic deviation-rectifying system on the throne of material carrying belt of vacuum belt type drying machine provided by the present invention, comprise correction information acquisition device, correction cylinder and computer control system, the correction information acquisition device places the both sides of material containing conveyer belt; The correction cylinder places the two ends of the adjustable power transmission shaft of material containing conveyer belt connecting gear, and its cylinder arm is connected with the slide block that adjustable power transmission shaft is installed; Computer control system is made up of electric control cabinet and computer, the correction information acquisition device is transferred to computer control system with material containing conveyer belt shifted signal, after machine is handled as calculated, driving the cylinder arm by electric control cabinet control correction cylinder moves, adjustable power transmission shaft moves under the effect of cylinder arm, make the reposition gradually of material containing conveyer belt, correction work is finished.
The present invention has following beneficial effect: realize instant automatic deviation correction on the throne, make the material containing conveyer belt keep straightaway all the time, avoid causing outage or conveyer belt impaired because of skew; Keep permanent continuous duty to improve the service efficiency of drying machine thereby help drying machine, do not need manual maintenance simultaneously; The adjustment of correction is fully by computer control, the accuracy height, and can be in equipment running process adjust automatically at any time, power transmission shaft can two-wayly be controlled the tensile force of conveyer belt, makes contact-making surface between the two remain evenly; Prolonged the service life of material containing conveyer belt, made the job stability of vacuum belt drier obtain comprehensive lifting.
