Below with reference to accompanying drawing, embodiments of the invention are done to concrete explaination.
A kind of new type washing machine disc brush mechanism of the embodiments of the invention as shown in Fig. 1 to 7, comprises disc brush 1, disc brush shaft assembly, swing mechanism and elevating mechanism.But one end of being located at disc brush shaft assembly that disc brush 1 self is rotated, disc brush shaft assembly is connected with swing mechanism, and swing mechanism drives disc brush shaft assembly to swing.Elevating mechanism is connected with disc brush, and elevating mechanism drives disc brush lifting moving.As shown in fig. 1, disc brush 1 is provided with silk hair, and the string diameter of silk hair is 0.3 ± 0.05mm, is preferably 0.3mm, is less than or equal to 0.2mm.
The disc brush silk nominal diameter of embodiments of the invention is little, flatness is high, avoids part contact glass not only affect clean but also easily scratch glass surface.
Disc brush is not only wanted the surface of cleaning glass, and glass surface is also had to abrasive action, therefore disc brush silk hair flatness and elasticity are very crucial, and Large-Area-Uniform contacts glass surface and has certain elasticity and can under the prerequisite of clean and abrading glass, avoid scratching glass and excessive compression glass.Embodiments of the invention change string diameter into 0.3 millimeter by repetition test, and flatness is strict controlled within 0.2 millimeter, avoid part contact glass not only to affect and clean but also easily scratch glass surface.
As shown in fig. 1, in an embodiment of the present invention, disc brush shaft assembly comprises disc brush axle 2 and belt wheel 3.Disc brush axle 2 is rotatable to be located in disc brush shaft assembly, and one end of disc brush axle 2 is connected with disc brush 1, and the other end of disc brush axle 2 is connected with belt wheel 3.
Preferably between disc brush axle 2 and disc brush shaft assembly, be connected by deep groove ball bearing 4.Between disc brush axle 2 and belt wheel 3, be connected by oblique angle jackscrew 5.Between disc brush axle 2 and disc brush shaft assembly, also locate by shaft block ring 6, prevent disc brush axle 2 axial floats by jackscrew, back-up ring and deep groove ball bearing.
Preferably belt wheel 3 is provided with the Lightened structure of hollow.Between belt wheel 3 and disc brush axle 2, be also provided with edge steel bushing 7 processed, guarantee that aluminium alloy belt wheel 3 and disc brush axle 2 wear and tear.
For making disc brush shaft assembly axial bearing capacity as far as possible little, when embodiment of the present invention design belt wheel, consider Lightened structure, so just reduce rotary resistance and axial float power; Cannot normally complete the clean of glass surface and grind because the upper and lower play of disc brush axle causes disc brush, reliable and stable not while causing whole disc brush mechanism to use, design axle is connected and fixed mode, and to change oblique angle jackscrew into spacing, looseningly makes the upper and lower play of disc brush axle affect stability because locking nut after operation a period of time there will be; For anti-bearing is stuck and exist axial thrust to cause disc brush shaft assembly axial float and the difficult demolition and maintenance of locking, change angular contact ball bearing into deep groove ball bearing.
As shown in Fig. 2 to 4, in an embodiment of the present invention, swing mechanism comprise connected successively motor 8, reductor, perch 9, be located at two eccentric shafts 10 at perch 9 two ends, two connecting rods being connected with two eccentric shafts 10 respectively 11, two the little axles of connecting rod and two forks 13.Motor 7 rotates by reductor 8 drive link main shafts 9, and perch 9 drives two connecting rods 11 to rotate by eccentric shaft 10, is located at two eccentric shaft 10 Central Symmetries at perch 9 two ends.
Every cleaning machine of the embodiment of the present invention configures 4 groups of disc brushes altogether, self rotation and the adjacent dislocation swing of disc brush have formed a compound motion, this compound motion can make the working range of disc brush cover the upper surface of whole glass, otherwise there will be glass part repeated washing or leakage to wash, occur that demoulding or overmastication squeeze cullet defect.Eccentric shaft 10 in swing mechanism device is the design of left and right Central Symmetry, when assembling, installs symmetrical two adjacent groups disc brush swing mechanism eccentric shaft 10, and when disc brush is moved like this, dislocation swings rather than synchronously swings, and avoids causing repeated washing or leakage to wash.
