Detailed description of the invention
As Fig. 1, shown in Fig. 2 and Fig. 3, damping regulates driving valve gear, comprise housing 1, valve plate 2, rotating shaft 3, traveller 4, oil cylinder 5, reductor 6, first limit switch 7, second limit switch 8 and angular displacement indicating device 10, valve plate 2 is arranged in rotating shaft 3, rotating shaft 3 is connected with the output shaft of reductor 6, traveller 4 is connected with the piston rod of oil cylinder 5 by locknut 9, oil cylinder 5 is arranged in gripper shoe 13, gripper shoe 13 is connected with housing 1 by pillar 14, reductor 6 is arranged on housing 1, first limit switch 7 and the second limit switch 8 are arranged on the two ends up and down of pillar 14 respectively, angular displacement indicating device 10 is arranged on reductor 6, the lower end of traveller 4 is provided with discharge station 11, the centre of traveller 4 is provided with feed station 12, when damping regulates driving valve gear to work, melt flows in housing 1 through this device, the passage of traveller 4 is entered into by valve plate 2, enter into upstream device again, it is inner that material enters housing 1, rotating shaft 3 is driven to rotate by reductor 6 output shaft, the valve plate 2 be arranged in rotating shaft 3 is rotated, reach the effect regulating melt pressure, make the invariablenes turning speed of valve plate 2 at the low cruise of 0.27 rev/min by the reductor 6 of big retarding ratio, the adjustment aperture of the steady safety of remaining a constant speed when valve plate 2 is rotated and reverse, by angular displacement indicating device control and regulation aperture, melt in this device by valve plate 2 and housing composition cavity in there is certain barometric gradient, ensure material be fed forward smoothly, driving valve, by the piston rod knee-action of oil cylinder 5, is driven the traveller 4 be connected with piston rod by locknut 9 to move up and down, realizes the conversion of discharge station 11 and feed station 12, by the accurate limiting of the first limit switch 7 and the second limit switch 8, the first limit switch 7 and the second limit switch 8 also can adopt safety switch or displacement transducer to replace, and make discharge station 11 and feed station 12 accurately and reliably, material carries out the discharge of waste material by entering into discharge station 11 after valve plate 2, be transported to again in upstream device after entering feed station 12, melt is by damping valve housing 1 and valve plate 2, by the normal operation of reductor 6, drive rotating shaft 3 and valve plate 2 to rotate, make the aperture of valve plate 2 controlled, control the pressure of melt in machine barrel, improve the melting mixing plasticizing rate of material, thus reach the effect of flow restriction control, the state that driving valve makes melt be in discharge station 11 by oil cylinder 5 action carrys out waste discharge material, or the state making melt be in feed station 12 carrys out normal convey materials to heading, then enters into upstream device.
The operation principle of this device is material after the mixing shearing plasticizing of machine barrel and screw rod, enter into damping and regulate driving valve, the valve plate of orifice valve is driven to rotate by driven by motor decelerator, the rotation of valve plate can make the circulation area of the stream by orifice valve change thereupon, thus control the pressure of melt in machine barrel, improve the melting mixing plasticizing rate of material, thus reach the effect of flow restriction control; In the driving starting stage, the raw material do not plastified completely in a large number and the material being mixed with impurity is there is in pugging extruder, easily the forming hole of template is blocked, driving valve can control the direction of switching valve by hydraulic jack, material is discharged from bypass, in time normally producing, forward driving valve to stream direction again, stream is made to be transformed into heading, be transported in upstream device, the designing requirement of this device: damping regulates driving valve gear first will consider reasonability and the security reliability of structure in design; Secondly on the basis of practical function, make its processing and manufacturing easy, easy and simple to handle as far as possible, reduce labour intensity, in its process, will ensure that melt plays the effect regulating melt pressure when overdamp control valve; Valve plate rotates freely, and the aperture of valve plate is adjustable; Melt is normally fed forward smoothly; The conversion traveller action of driving valve is safe and reliable; Driving valve can be discharged to below melt, also heading can be transported to smooth and easy for melt, the utility model damping regulates driving valve gear, great role is played in quality improvement for material in granulation process, damping regulates the performance of driving valve quality directly to have influence on the success or not of granulation, by the valve plate aperture of damping adjusting valve, can control the pressure of melt in machine barrel, improve the melting mixing plasticizing rate of material, thus reach the effect of flow restriction control; In the driving starting stage, there is the raw material do not plastified completely in a large number and the material being mixed with impurity in pugging extruder, easily blocked by the forming hole of template, material can be discharged from bypass by switching valve by driving valve, in time normally producing, then stream is transformed into heading.
