Technical field
The utility model relates to a kind of gluing auxiliary equipment, more particularly, relates in particular to a kind of for controlling the accurate slack adjuster of bondline thickness and inhomogeneity metering roll.
Background technology
At present, the slack adjuster generally adopting in gluing industry has three kinds substantially, the one, with the bearing block of screwed push rod head top metering roll, the 2nd, by screwed screw mandrel drive voussoir linear slide, regulate the gap of two metering rolls by the inclined-plane of voussoir, the 3rd, regulate the structure in the gap of two metering rolls with camshaft; More complicated and the machining accuracy of the structure of first two device and cost are all very high, particularly regulate the device in metering roll gap by voussoir inclined-plane, because the screw thread of screw rod and voussoir cooperation exists certain gap, so, in the time that voussoir moves forward and backward, just exist the error in gap, and the error in gap can directly have influence on the adjustment precision in two metering roll gaps.Although camshaft is simple in structure, the precision and stability regulating is all poor.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide a kind of rational in infrastructure, energy consumption is low, good stability and the easy to operate accurate slack adjuster of metering roll.
The technical solution of the utility model is achieved in that the accurate slack adjuster of a kind of metering roll, comprises the holder and the Mobile base that are oppositely arranged, and described Mobile base is connected with horizontal drive apparatus; On holder, be provided with fixing metering roll, on Mobile base, be provided with the movable metering roller matching with fixing metering roll, on wherein said holder, be respectively equipped with worm-gear speed reducer and screw bolt seat, described worm-gear speed reducer is connected with rotating driving device, the along continuous straight runs adjusting screw(rod) that has been threaded on screw bolt seat, wherein one end of described adjusting screw(rod) is connected with the hollow shaft of worm-gear speed reducer; On the holder end face relative with Mobile base, be provided with tip-lever support, be hinged with push rod on tip-lever support, the free end of described push rod is corresponding with adjusting screw(rod), and push rod promotes by adjusting screw(rod), is provided with the jacking block relative with Mobile base at push rod middle part.
In the accurate slack adjuster of above-mentioned metering roll, the holder of described jacking block side is provided with range finding probe, and described range finding probe is connected with external device circuitry.
In the accurate slack adjuster of above-mentioned metering roll, between described push rod and holder, be connected with extension spring.
In the accurate slack adjuster of above-mentioned metering roll, described Mobile base sidewall is provided with the block corresponding with jacking block.
In the accurate slack adjuster of above-mentioned metering roll, described horizontal drive apparatus is cylinder.
In the accurate slack adjuster of above-mentioned metering roll, described rotating driving device is any one of motor, air motor and handwheel.
The utility model adopts after said structure, push rod is hinged on tip-lever support, its free end is corresponding with adjusting spiral shell, at push rod middle part, jacking block is set simultaneously, this is the principle that has adopted swing arm, make jacking block when stressed, the power that adjusting screw(rod) bears is less, this structure, make worm-gear speed reducer drive the adjusting screw(rod) needed moment of torsion of when rotation also can be very little, needed drive source will be very little, and the power therefore consuming when this device busy will be very little, can greatly save energy consumption, and the service life that can improve reductor.Secondly, jacking block is arranged on the middle part of push rod, and the amplitude of oscillation of push rod jacking block in the time swinging is compared and can be reduced at double with the amplitude of oscillation of push rod head, can also improve widely like this precision that regulates gap.In addition, because jacking block directly contacts with the block on Mobile base, under reaction force, can eliminate the screw thread of adjusting screw(rod) and the thread pitch of screw bolt seat, so the gap error of screw thread is very little on metering roll impact when rotated for adjusting screw(rod).Owing to having adopted worm-gear speed reducer, adjusting screw(rod) has good self-locking performance after adjusting puts in place.This device mounted in pairs is in the two axial ends of glue spreader metering roll, and the gap to metering roll and the uniformity of rubberised layer are carried out high-precision adjusting, simultaneously by the range finding numerical value gap situation of change of observing metering roll showing of popping one's head in.The utlity model has simple in structure, energy consumption is low, good stability, easy to operate advantage, especially to improving the uniformity successful of gluing, is a kind of desirable slack adjuster.
