Detailed description of the invention
Describe vibratory sieve of the present invention in detail below in conjunction with accompanying drawing, it will be appreciated by those skilled in the art that embodiment described below is only to exemplary illustration of the present invention, but not for making any restriction to it.
See Fig. 1, mainly comprise pedestal 1, horizontal shock-absorbing mechanism A, vertically supporting mechanism B, horizontal guide rail 7, bracket 2, screen assemblies 3 and motor 4 according to vibratory sieve of the present invention.Pedestal 1 has horizontal supporting portion 18 and vertical support portion 17, and vertical support portion 17 is positioned at the two ends of horizontal supporting portion 18.Horizontal shock-absorbing mechanism A is connected with the vertical support portion 17 of pedestal 1, and vertical supporting mechanism B is connected with the horizontal supporting portion 18 of pedestal 1.Horizontal guide rail 7 is connected respectively by the vertical support portion 17 of horizontal shock-absorbing mechanism A and vertical supporting mechanism B and pedestal 1 and horizontal supporting portion 18.Bracket 2 is used for fixing screen assemblies 3, and bracket 2 is movably connected on horizontal guide rail 7 by slide block 5.Motor 4 is arranged on pedestal 1, and the turning cylinder of motor 1 is connected with slide block 5 by crank 10, connecting rod 6.When motor 4 rotates, drive crank 10 to rotate, promote slide block 5 by connecting rod 6 and move on horizontal guide rail 7, the bracket 2 be fixed on slide block 5 is also reciprocating, thus drives screen assemblies 3 do left and right and move up and down.
Also see Fig. 2, horizontal shock-absorbing mechanism A comprises horizontal spring 9, bolt 11 and clamp nut 8, and vertical support portion 17 is provided with vertical shifting chute 12.One end of horizontal spring 9 is connected with horizontal guide rail 7, and the other end of horizontal spring 9 is connected with bolt 11.Bolt 11 is passed vertical shifting chute 12 and is fixedly connected with vertical support portion 17 by clamp nut 8, and before being fixedly connected with, bolt 11 can move up and down and position in vertical shifting chute 12.
Also see Fig. 3, vertical supporting mechanism B comprises vertical bar 16, uprighting spring 14 and stop nut 15, and horizontal supporting portion 18 is provided with locating hole 19.The lower end of vertical bar 16 is the end of thread, and the end of thread is connected with stop nut 15 through locating hole 19, and leaves gap between the end of thread and locating hole 19 thus vertical bar 16 can be moved up and down in locating hole 19.The upper end of vertical bar 16 is connected with horizontal guide rail 7.Vertical bar 16 is provided with end cap 13, and the upper and lower side of uprighting spring 14 is connected with end cap 13 and horizontal supporting portion 18 respectively and is socketed in the lower, outer perimeter of vertical bar 16.When vibratory sieve works, uprighting spring 14 has certain vertical tremor, and the material in screen assemblies 3 can be shaken up and down, which increases the screening effeciency of material.
Above-mentioned horizontal shock-absorbing mechanism A and vertical supporting mechanism B uses nut to fix lower spring end, only need dismantle nut, make itself and base-separation, saved the time, improve efficiency when changing spring.
Also see Fig. 4, horizontal shock-absorbing mechanism A and vertical supporting mechanism B is respectively four, is symmetricly set on the two ends of horizontal guide rail 7 respectively.When the advantage of this design is that of avoiding single spring as support member, roll the screen assemblies shakiness and the wearing and tearing to spring that cause of spring.
Introduce operation principle and the method for operating of vibratory sieve of the present invention below.
The screen assemblies 3 that granular materials to be sieved (such as medicament powder) will be housed is fixing on carrier 2, regulate the Oscillation Amplitude of screen assemblies 3 according to actual needs, starter motor 4, motor shaft drives crank 10 to rotate, promote slide block 5 by connecting rod 6 to move on horizontal guide rail 7, also drive horizontal guide rail 7 to do curvilinear motion simultaneously.The bracket 2 be fixed on slide block 5 is also reciprocating, thus drives screen assemblies 3 vibrate thus carry out effective separation of granular materials.The curvilinear motion of horizontal guide rail 7 is decomposed into horizontal movement and vertical motion.Horizontal movement is cut down by horizontal shock-absorbing mechanism A; Vertical motion going down is to end cap 13, and uprighting spring 14, along with end cap 13 together vertical tremor, reaches the effect of damping.By the damping of horizontal shock-absorbing mechanism A and vertical supporting mechanism B, the stability of vibratory sieve effectively can be improved.
When need change screen assemblies 3 Oscillation Amplitude time, horizontal shock-absorbing mechanism A and vertical supporting mechanism B can be changed simultaneously.By bolt 11 is changed up and down in vertical shifting chute 12, and add with nut 8 and fasten, regulate horizontal shock-absorbing mechanism A.By the deformation quantity regulating the upper-lower position of stop nut 15 on vertical bar 16 to change uprighting spring 14, thus regulate vertical supporting mechanism B.Achieved the change in location of horizontal guide rail 7 by above-mentioned regulating measure, the stroke of slide block 5 is changed, thus change the Oscillation Amplitude of screen assemblies 3.By the adjustment to Oscillation Amplitude, the requirement of different screening condition can be adapted to.
