Abstract
The utility model relates to a hydraulically-driven rubber and plastic open mill and a hydraulically-driven calender, which are characterized in that a power source of the machine is a hydraulic motor instead of an electric motor. A hydraulic station (1) outputs high-pressure hydraulic oil to push the hydraulic motor (2) to rotate; and an output shaft of the hydraulic motor (2) is directly connected with rollers (5), so that the rollers (5) are driven to rotate. Each roller is independently driven, so that a speed ratio between the rollers is flexibly adjustable; for a large-scale high-power open mill and a large-scale high-power calender, the hydraulic motor (2) can be additionally arranged at each of the two ends of each roller (5) for synchronous driving; the roller distance is adjusted by distance adjusting hydraulic cylinders (6) at the two ends of each roller (5); and the hydraulic station (1) is provided with voltage stabilizing, self-locking, speed adjusting and synchronizing hydraulic circuits and the like, so that the rollers (5) can stably run at low speed and high torque, and the roller distance can be accurately adjusted.
Description
Technical field:The utility model relates to hydraulically powered rubber and plastic opening rubber mixing machine of a kind of employing and calender.The power source that is characterized in machine is hydraulic motor rather than motor.
Background technology:At present, the core component roller of known mill and calender comes driven in rotation by motor through reductor.The power of this kind equipment is bigger, and the volume and weight of motor and reductor is also very big, causes the complete machine heaviness and huge, and this not only wastes great deal of steel, increases manufacturing cost, brings inconvenience also for device layout, installation, transportation etc.Owing to mechanically operated qualification, the speed ratio between mill or the calender two adjacent rollers is fixed, and can't adjust according to the difference of machined material and technological requirement, thereby can not give full play to the technical performance of equipment in addition.
The utility model content:The purpose of the utility model is the deficiency to above-mentioned conventional ADS driving mode, designs a kind of roller that adopts fluid motor-driven mill or calender, replaces original motor and reductor.
The purpose of the utility model is achieved in that the pressure oil of Hydraulic Station output through loop of voltage regulation, speed control loop supply hydraulic motor, promotes its rotation.The rotating speed of hydraulic motor is very low and adjustable, does not therefore need the reductor deceleration can directly drive the roller rotation of mill or calender.Because roller is a drive, but the speed ratio step-less adjustment between the two adjacent rollers.Roll spacing between the roller adopts hydraulic jack to regulate.This kind of drive has replaced the mechanical drive mode of original motor and reductor fully.
The advantage of hydraulically powered mill and calender is obvious: at first hydraulic motor has the characteristic of low speed high torque and the advantage of controlled accurate stepless speed regulation, thereby the comprehensive technical performance of mill and calender is increased dramatically.Secondly the control of hydraulic system very easily realizes automation, and human-machine operation is simple and convenient, can realize people's multi-machine operation, saves labour cost.Owing to removed bulky motor and reductor, can make the overall volume of mill and calender and weight reduce about 1/3-1/2 in addition, practice thrift manufacturing cost greatly, taken up an area of expenses such as space and installation and transportation.
Description of drawings:Below in conjunction with accompanying drawing and embodiment the utility model is further specified
Fig. 1 is the appearance assumption diagram of the utility model
Fig. 2 is a roller roll-setting gear structure chart
Among the figure: 1 Hydraulic Station, 2 hydraulic motors, 3 bearing blocks, 4 frames, 5 rollers, 6 roll adjustment hydraulic cylinders
7 roll adjustment piston rods, 8 safety discs
The specific embodiment:As shown in the figure, the high-pressure and hydraulic oil after the voltage stabilizing of Hydraulic Station (1) output process, the speed governing gets into hydraulic motor (2) through control valve, and hydraulic motor under the promotion of hydraulic oil (2) begins rotation, can convert hydraulic pressure into mechanical energy.The shell of hydraulic motor (2) is fixed on the bearing block (3), and bearing block (3) places frame (4).The output shaft of hydraulic motor (2) is connected with roller (5), can direct driving roller (5) when hydraulic motor (2) rotates.Because hydraulic motor has the characteristic of low speed high torque, meets the mechanical performance of mill and calender.Two adjacent rollers need rotate with different speed when work; And the utility model adopts the mode of each roller single driving; Accurately stepless speed regulation of hydraulic motor, so mill and calendering function are according to the raw material of different formulations and the technological requirement speed ratio of adjustment two rollers arbitrarily.Can all install hydraulic motor (2) additional at roller (5) two ends for large-scale high-power mill and calender, driven in synchronism roller (5) rotation.The adjusting of roll spacing is to accomplish through the roll adjustment hydraulic cylinder (6) that is installed in roller (5) two ends.Inject the left chamber or the right chamber of roll adjustment hydraulic cylinder (6) from the high-pressure and hydraulic oil of Hydraulic Station (1) respectively through the manipulation of reversal valve, promote roll adjustment piston rod (7) and advance or retreat.Roll adjustment piston rod (7) is connected with bearing block (3) and roller (5), realizes the adjusting of two adjacent roller roll spacings.Safety disc (8) is cracked when excess load, in case device damage.Hydraulic Station (1) has voltage stabilizing and self-locking circuit can guarantee the dancer rools distance that roll adjustment hydraulic cylinder (6) is accurate, synchronous, constant.
The main body motion of rubber and plastic opening rubber mixing machine and calender is the rotation of roller and the adjusting of roll spacing.The utility model replaces the mechanical drive mode of conventional motors and reductor and realizes full hydraulic drive.
