Puddler adopts stainless steel welded, in 15 ° of angles between blade and knee vertical axis, the hollow guiding steel pipe side of upper end, support body (11) right side is provided with lock-screw (16), the structural framing that electrical control cabinet (17) is fixedly mounted on the steel-pipe welding of support body (11) is inner, protective cover (21) is fixed in the upper plane of the framework of support body (11) steel-pipe welding by four hex bolts (22), and resin paint can (2) surrounds therein by entirety.
Bung (1) button is placed on the top of resin paint can (2), and puddler (20) passes in the circular hole at bung center.
Operation principle of the present invention:
1, mixing plant adopts the glue bucket mode that rotate relative to puddler to realize automatic stirring, the resin paint can seat of filling glue is housed on gantry, the transition axis that gantry is arranged on above helical speed reduction gear output shaft puts, and gantry, under the driving of reducing motor, drives resin paint can to do and at the uniform velocity rotates.Helical speed reduction gear is the drive unit of this equipment, adopt Tianjin reductor factory R series coaxial bevel gear speed reducer, smooth running, power of motor is 0.37kw, rated speed is 1440r/min, gearratio is 15.60, and the rotating speed of resin paint can is 1440/15.6=92.3r/min, meets technical requirement during work.
Puddler is steel welding part, the guide portion of puddler is inserted in upper end, the right side guiding steel pipe of support body, the keyway that guide portion lower end has the dive key of 2 8mm be arranged symmetrically with and support body to lead on steel pipe coordinates, both the moment of torsion in whipping process had been counteracted, can finely tune up and down the position of puddler in glue bucket again, the spacing of 10mm should be left between the blade of puddler and the bottom surface of resin paint can, by the lock-screw on the guiding steel pipe of upper end on the right side of support body, puddler is reliably locked after adjustment.This equipment helical speed reduction gear drives filling glue bucket one direction to operate continuously, and puddler has enough rigidity, electric control operation process is simple, automaticity is high, only need to press startup, stop button, stir so filling glue can be reached, enhance productivity, reduce the effect of labour intensity, achieve considerable economic benefit.
2, injection device adopts pollution-free compressed air as power source, drives air pump piston to move to the extraction of filling glue, injection work by air motor; Along with the decline sucker of filling glue liquid surface in glue bucket declines under the effect of support cylinder simultaneously, realize the free of discontinuities extraction of filling glue, injection work.
Air motor selected by equipment, the pressure ratio of pump are 63:1, ensure to obtain under very little input pressure very large to take out, note pressure, realize filling the extraction of glue, conveying, injection to high viscosity; Selected air pump delivery is 100 milliliters, and can realize the injection work to 6 liters of glue per minute, the filling glue realized hardening time is short carries out high efficiency conveying; For preventing filling glue the corrosion pump housing, internal piston, sucker, the pump housing, internal piston, sucker all adopt stainless steel; Convenient for meeting operated from a distance, be provided with stop valve by carrier pipe end, after a gap, place has been noted, namely closedown stop valve equipment quit work; At air motor, import department is configured with oil water separator, prevents moisture in compressed air from entering motor inner chamber, and arranging overflow valve can adjust motor admission pressure according to actual requirement; Carrier pipe has high pressure resistant, corrosion resisting property; Whole equipment, by moveable dolly, is convenient to flexible operation.
During use, stator is sleeping to be placed on electric roller frame, and startup turning rolls makes stator region to be filled go to and requires position, three mixers are respectively put at stator two ends, two injection devices, to carrying out anti-drain process in stator end, glue barreled is on mixer, resin is poured in glue bucket, adds curing agent, and fixing puddler is in frame, start mixer motor, stir after 3 minutes, in bucket, add filler on request, after stirring, glue bucket is pulled down.Carrier pipe one end is inserted and is arranged in the propylene pressing plate inlet of stator end, and the other end is connected with air pump gum outlet; Pump sucker inserts in glue bucket, according to adhesiveness adjustment air motor import department overflow valve, makes admission pressure to required value, opens sucker charge valve, starts extraction, conveying injection work that pump carries out glue.Region to be filled is full of and after solidifying, and starts turning rolls and next region to be filled of stator is gone to require position, repeat the filling work that above-mentioned action completes epoxide-resin glue.
The technology of the present invention effect:
1, reducing motor adopts Helical gear Transmission, and operate steadily, noise is little, and gearratio is 15.60, and the rotating speed of glue bucket is 1440/15.6=92.3r/min, meets the stirring work that glue filled by most stator.
2, puddler is stainless steel welded, and in 15 ° of angles between blade and knee vertical axis, when glue bucket rotates, blade is inclined in resin glue stirs, and reasonable stress, can prevent resin filling glue from upwards turning over from resin glue bucket portion and gush.
3, gantry surrounding respectively has a jackscrew and rubber blanket, can effectively buffering adhesive bucket rotate time produce vibration, equipment is shielded.
4, structure is more simple, rationally, use is more reliable, alleviates weight, reduces cost.
