Embodiment
Below, substantive distinguishing features of the present utility model and advantage are further described with reference to example, but this practicality is new Type is not limited to listed embodiment.
Referring to shown in Fig. 1-4, a kind of twin-screw oil mill for aiding in automatically adjusting squeezing breech pressure, including twin-screw squeeze Oil machine body, the twin-screw oil mill body have press chamber 10 (or for squeeze cage) and a Chu Bing mechanisms 11, it is described go out cake machine Structure include cake seat 110, with it is described go out cake seat two formed with biscuit tapping channel 13 cake exit ring 111 (or for cake Head), the press chamber, which is provided with, to be used to detect the pressure sensor for squeezing breech pressure, and each cake exit ring passes through an axis of rolling Hold 112 one end respectively with two adjusting screw rods 113 to be connected, one is respectively equipped with the other end of two adjusting screw rods Straight spur gear 114, two straight spur gears are meshed, and an adjusting screw rod by PLC with being controlled The output shaft of the regulation motor 115 of rotation direction is connected, and the PLC connects the pressure sensor.
Wherein, the PLC controls are connected with regulation motor driver.By setting regulation motor at Chu Bing mechanisms, Regulation motor is connected with PLC, and PLC is connected with the pressure sensor in press chamber, forms a closed-loop control system System, eventually through the regulation for going out cake amount and realizing squeezing breech pressure in control Chu Bing mechanisms.
During work, detecting the pressure in press chamber more than preset pressure value or less than preset pressure by pressure sensor During value, PLC controls to adjust motor rotation, and controlling to adjust screw rod by straight spur gear rotates, and realizes in right and left Move up, adjusting screw rod promotes rolling bearing, and then promotes cake exit ring to move in the lateral direction.When squeezing, breech pressure is excessive When, adjusting screw rod moves right, and the material in press chamber directly pushes cake exit ring to the right, and cake is thickening, goes out the increase of cake amount.When in press chamber When pressure is too small, adjusting screw rod is moved to the left, and to the left, cake is thinning for cake exit ring, goes out the reduction of cake amount.
Chu Bing mechanisms are the feedbacks of the pressure sensor by being filled on the squeezing bar in press chamber, drive the rotating of stepper motor Come what is be adjusted.When squeezing breech pressure in pressure limit, stepper motor does not work;When squeezing breech pressure is not in pressure model When enclosing interior, stepper motor meeting forward or reverse carries out the adjustment of one or several angles, drives straight spur gear to rotate, and then Drive the rotating of two adjusting screw rods.Screw thread is wherein furnished with adjusting screw rod, goes out the adjusting screw rod mounting seat of cake support frame The screw thread of internal thread hole and adjusting screw rod coordinate, and on two adjusting screw rods screw thread it is oppositely oriented, with ensure two regulation Screw rod adjusts to same direction.Go out the number of cake eventually through the unit interval to control the pressure value in press chamber.
In specific implementation, perforate, installation high temperature melt pressure sensor measurement can be carried out in corresponding position in press chamber Radial pressure therein, the pressure value measured is transferred to PLC, PLC reads the signal, and by the signal with The pressure limit value pre-set is made comparisons, and judges the signal whether in pressure limit, and the final result output that will determine that Corresponding control signal, stepper motor driver is transmitted the signal to, driving stepper motor stepper motor rotates, and then realizes The rotation for the straight spur gear being connected with adjusting screw rod, straight spur gear drive turn of two adjusting screw rods simultaneously again It is dynamic, the regulation of grouts thin and thick is realized, it is final to realize the regulation for squeezing breech pressure.
It should be noted that in the utility model, the pressure sensor is connected with PLC, and PLC is with adjusting Motor driver connection is saved, is realized by PLC according to the pressure value of setting and the pressure in the press chamber of pressure sensor detection Force value compares the control signal of output regulation motor, is existing ordinary skill to control to adjust the rotation direction of motor Known control technology known to personnel, its adjusting control circuit is no longer described in detail, specifically such as Disclosed in CN201220124149.7 granted patent technologies PLC connection pressure sensor, stepper motor driver with And stepper motor, to control the control technology of stepper motor forward and backward, PLC selects FX2N, and pressure sensor uses MDA422 high temperature melt pressure sensors.
