Moving gear 2 is engaged with the transmission shaft of external power motor 3, for driving shaft to rotate.In an embodiment of the present invention,
One end of drive link 4 is arranged close on the outside of containers baffle 6 of the side of drive link 4, other end installation
On the edge of driven pulley 1.In order to swing container smoothly, one end of drive link 4 is fixed on close to drive link 4
The lower part of the outside of containers baffle 6 of side；For the driven pulley 1 of identical size, in order to realize the full swing of container
The edge of outside of containers baffle 6 is fixed at amplitude, 4 end of drive link (i.e. lower end) connecting with outside of containers baffle 6.It is preferred that
Ground, the material of drive link 4 are nonmetallic materials, further preferably PVC or PP material.Equipment work when, driven pulley 1 by
Exterior motor (i.e. power motor 3) is by the driving rotation of transmission gear 2, and the rotary motion of driven pulley 1 can drive transmission
Rod piece 4 moves, so that container 7 can do alternate rotary motion by a small margin clockwise and anticlockwise around central axis 5.When
When the end (i.e. upper end) for the drive link 4 connecting with 1 edge of driven pulley reaches the highest point of driven pulley 1, container 7 is put
It moves to extreme higher position, when the end for the drive link 4 connecting with 1 edge of driven pulley reaches the minimum point of driven pulley 1,
Container 7 has swung to extreme lower position, and with the rotation of driven pulley 1, the upper end of drive link 4 moves in a circle, thus band

Preferably, the hunting frequency f of nonmetallic vessel (controls the swing of nonmetallic vessel by the velocity of rotation of shaft
The range of frequency f) is 1r/min < f < 30r/min, and the excessively high product that will increase of hunting frequency knocks side ratio, and frequency is too small to be will lead to
Product surface can not be contacted uniformly with phosphating solution, influence quality of forming film；Preferred range is 4r/min < f < 10r/min；
Nonmetallic vessel amplitude of fluctuation is determined by the diameter of pulley in transmission mechanism, it is preferable that the model of the diameter D2 of pulley
Enclosing is 50mm < D2 < 300mm, and preferred range is 80mm < D2 < 150mm.
Preferably, the range of phosphating time tm is 1min < tm < 120min, and the time is too short, and phosphating coat covering is imperfect, when
Between too long will affect production efficiency；Preferred range is 10min < tm < 30min.
Preferably, the range of phosphatization temperature Tp is 20 DEG C < Tp < 100 DEG C, changes too high or too low for temperature can not all be formed effectively
Phosphating coat, it is serious if product surface can not will form phosphating coat completely；Preferred range is 40 DEG C < Tp < 60 DEG C.
