Abstract
The utility model mode provides a planetary rotor sand mixer for moulding molding sand. The crosshead (6) rotating at a low speed and rotors (4, 8) rotating at a high speed are respectively driven by power output shafts (3, 5) with different speeds, which avoids the unreasonable driving mode of first speeding down and then speeding up of the power source of the existing sand mixer. The sand mixer can get the satisfactory mixing effect on molding sand with different performance requirements by selecting the rotors (4, 8) of different shapes, especially for the mixed producing towards the coated sand and soluble glass sand.
Description
Utility model relates to a kind of molding sand that is used for Foundry Production and mixes control equipment.
In Foundry Production, the mixed system quality of molding sand is the key factor that influences casting quality.Therefore, the improvement to the mixed control equipment of molding sand has practical meaning.In existing various puddle mixers, rotator mixed sand machine is a class mixing efficiency height, and the low equipment that consumes energy.Utility model promptly is the improvement to disclosed a kind of planet rotor puddle mixer among the Chinese patent CN85200226.Existing this planet rotor puddle mixer, mainly comprise actuating unit and a staving, planet rotor mechanism is housed in staving, this planet rotor mechanism comprises the crosshead of a rotation and the scraper plate of close the staving bottom surface of rotating synchronously with crosshead, and the rotor with crosshead revolution and energy rotation is equipped with at the crosshead two ends.The kind of drive of this planet rotor mechanism is to drive crosshead by an axle (unique output shaft of decelerator) low speed ground to rotate, and rotates the high speed of the rotor self of (revolution) with crosshead and rotates (rotation) and come speedup by sun gear and planetary gear and be installed in the crosshead two ends.Like this, after decelerator slows down again speedup increased the consumption of useless power from transmission principle shortage economic rationality, simultaneously axle bear the transmission of dynamic power, its rotating speed is low again, so its moment of torsion of bearing is very big.
For this reason, utility model provides a kind of planetary rotator mixer, is to the improvement of above-mentioned existing planetary rotator mixer, improves the economic rationality of its transmission, reduces the consumption of useless power, reduces the size of axle, reduces manufacturing cost.
Utility model is achieved in that the needed power power of rotor mechanism, be the power on the required high speed shaft of power on the required slow-speed shaft of crosshead and rotor, transmit by the speed of suit different hollow shaft and axle respectively, promptly bear the big hollow shaft of torque capability and drive crosshead, bear the little axle of torque capability and drive rotor, obviously so just avoided the existing problem of above-mentioned planet rotator mixed sand machine.
Fig. 1 is the front view of the planet rotor puddle mixer that provides by utility model.
Fig. 2 is the attached view of Fig. 1.
The planet rotor puddle mixer that utility model provided, mainly comprise actuating unit and a staving 10, planet rotor mechanism is housed in staving, this planet rotor mechanism comprises the crosshead 6 of a rotation and the scraper plate 9 of the close staving bottom surface of rotating synchronously with crosshead, crosshead 6 two ends have at least an end to be equipped with crosshead revolution and rotor 4 that can rotation, 8, the feature of utility model is: said actuating unit drives a hollow shaft 3 with the speed rotation the end of than, and hollow shaft drives crosshead 6 and scraper plate 9 rotates, simultaneously, actuating unit also drives the axle 5 that is sleeved in the hollow shaft 3 and rotates with higher speed, and axle 5 drives the rotor 4 that is contained on the crosshead by transmission mechanism 7,8 rotations.Utility model is actually the crosshead that will slowly run and is driven by the different power output shaft of speed respectively with the high speed rotor rotated, avoided power source to slow down earlier and the problem of speedup, reduced the consumption of useless power, also avoided simultaneously dynamic torque entirely by the shortcoming that axle is transmitted, 3 speed are low because utility model is hollow shaft, and the moment of torsion of bearing is big, axle 5 speed height, the moment of torsion of bearing is little, has therefore improved the economic rationality of its transmission.
The hollow shaft 3 of utility model and the axle 5 that is sleeved in the hollow shaft can be two independently output shafts of decelerator, and scheme is two output shafts that speed is different as same decelerator 2 preferably.
Fig. 1 and Fig. 2 have provided a kind of example of planet rotor puddle mixer.Molding sand is mixed by planet rotor mechanism in staving 10.Its structure and operation principle are: motor 1 drives decelerator 2, at least have two in-line gears that vary in size 13,14 in this decelerator 2, wherein 11 engagements of the gear wheel on pinion 13 and the hollow shaft, and less gear 12 engagements on gear wheel 14 and the axle.Then hollow shaft 3 drives crosshead 6 and scraper plate 9 rotations that are serpentine with lower speed, the rotor 4,8 that is contained in the crosshead two ends rotates (revolution) with crosshead, 5 rotor 4,8 rotations (rotation) that are contained in the crosshead two ends with higher speed by chain drive 7 drives of axle simultaneously.
Above-mentioned decelerator 2 can also adopt planetary transmission or differential gearing.
Another preferred scheme of utility model is at the two ends of crosshead 6 rotor 4,8 to be housed respectively, and one of them rotor 8 is flat, and its periphery is tangent close with the madial wall of staving 10.Such structure can be eliminated the scab of staving sidewall 2 by the running of rotor 8, and does not need the wall scraper plate of ad hoc anti-scab, thereby simplifies the structure, and has saved power consumption.
The planet rotor puddle mixer that utility model provided, can be used for multiple casting sand or the similarly mixing of bulk material, select difform rotor 4,8, as straight chip, oblique sheet type, comb formula, bar type etc., can obtain satisfied mixed effect to the molding sand that different performance requires, particularly for the mixed system of shell coated sand and water-glass sand, its best results.
