Description
Technical field
The present invention relates to the pick-up unit of slide fastener, be specially a kind of pressure-sealing zipper to-and-fro movement testing machine.
Background technology
Pressure-sealing zipper is as the vitals in weapon packaging, and its sealing and serviceable life are two important indicators.
At present, existing slide fastener testing machine is rectilinear path, and this testing machine limits by experiment place, and be generally all designed to the slide fastener of length within satisfied 3 meters, the slide fastener that cannot adapt to more than 3 meters length is back and forth tested, and floor area is large.
Summary of the invention
The object of the present invention is to provide a kind of novel pressure-sealing zipper to-and-fro movement testing machine, this testing machine laboratory take up space be long 1500mm, wide 750mm, high 800mm, the slide fastener within 1-18 rice can be adapted to, the space requirement in laboratory can be met completely.
The present invention adopts following technical scheme to realize:
A kind of pressure-sealing zipper to-and-fro movement testing machine, comprises motor, and the output shaft of described motor drives connection reducer; Output terminal coaxial drive two small synchronous pulleys of described speed reduction unit rotate, two small synchronous pulleys rotate respectively by the large synchronous pulley of belt drives two, one of them large synchronous pulley drives revolver to rotate by left electromagnetic clutch, and another large synchronous pulley takes turns rotation by right electromagnetic clutch driving is right; The shaft end of two small synchronous pulleys installs electromagnetic brake respectively.
Described revolver and right wheel are respectively arranged with slide fastener clamper, described revolver and right take turns clamp the head end of slide fastener and tail end by respective slide fastener clamper after slide fastener is installed on revolver and right take turns between.
Zip on described slide fastener is fixed by zip clamper.
The head end of described slide fastener and tail end are respectively arranged with spacing contact; The spacing contact at two ends is respectively used to trigger left limit switch and right limit switch.
Described left limit switch and right limit switch output signal to PLC respectively, and described PLC controls motor forward/backward rotation, controls two electromagnetic brake actions and control left and right electromagnetic clutch action respectively.
The man-machine conversation mode adopting PLC to control controls.Left and right rotation direction of taking turns is just in time contrary in test, need motor forward/backward rotation, and left and right wheel is all driving wheel, therefore in system, consider two electromagnetic clutchs, closed by the clutch coupling be arranged on left and right wheel shaft or be separated and carry out the left and right master/slave dynamic conversion taken turns.The zip of pressure-sealing zipper is by zip gripper and keep motionless, and pressure-sealing zipper moves under the left and right rotation taken turns, when pressure-sealing zipper moves to termination or end tail, motor must stop operating, need to arrange two limit switches, during limit switch action, motor stops operating.Again due to inertia effect, motor still continues to rotate after dead electricity, and zip can be caused like this to clash into zipper terminal or draw bad by zip, and therefore arrange electromagnetic brake in belt wheel termination, after making limit switch action, motor stops operating fast.This outside common tangent section arranges the adjustable limit switch in two positions and is used for commander's motor commutation and two electromagnetic clutch adhesives conversions.
In an experiment, of a slide fastener termination (head end or tail end) only need first be fixed on any one wheel (revolver or right take turns) this testing machine by operating personnel.Such as, during experiment, slide fastener clamper on the tail end revolver of slide fastener fixes by experimenter, manual mode is selected by PLC panel, revolver is set to driving wheel, press the motor start button on PLC panel, left electromagnetic clutch is in engagement state, right electromagnetic clutch is in separated position, rotating clockwise slide fastener around on revolver by revolver, press motor stop button, make the head end of slide fastener by left, right outside common tangent section of taking turns and right slide fastener clamper of taking turns are fixed, hand rotation revolver makes slide fastener tighten, adjust a left side, the position of right limit switch, zip and zip clamper are fixed, select rightly to take turns as driving wheel, automatic mode selected by PLC panel, actuating motor is tested.Now, right electromagnetic clutch is in engagement state, left electromagnetic clutch is in separated position, right wheel is rotated counterclockwise as driving wheel, slide fastener is wound to after progressively being taken off by revolver on right wheel, when the slide fastener solution on revolver is complete, left limit switch is touched in the spacing contact being positioned at zipper down end, left limit switch outputs control signals to PLC, PLC exports control signal and controls motor stopping, export the electromagnetic brake action that control signal controls to be positioned at right side small synchronous pulley simultaneously, make rightly to take turns quick stopping, then, PLC exports control signal and controls the separation of right electromagnetic clutch, export control signal simultaneously and control left electromagnetic clutch joint, control motor reversal afterwards, namely revolver turns clockwise as driving wheel, slide fastener progressively by right take turns take off after be again wound on revolver.So slide fastener is moved back and forth test.Carry out Auto-counting by photoelectric counter, when after the reciprocal time reaching setting, output signal to PLC, PLC controls to stop to motor, and electromagnetic brake starts effect simultaneously, until motor stall, experiment terminates.
The present invention according in " pressure-sealing zipper technical conditions " to the requirement in sealing, serviceable life and require zip travelling speed within the specific limits, design a kind of pressure-sealing zipper reciprocating tester controlled by PLC, alternately crankmotion is made by around pressure-sealing zipper on the driven wheel and driving wheel, zip is fixed in the outside common tangent position of two-wheeled, slide fastener and zip is made to form relative motion, leakage test is carried out again, to investigate the sealing of pressure-sealing zipper after the reciprocal time required.This testing machine is reasonable in design, and equipment composition is comparatively simple, input cost is lower, easy to operate.
