Abstract
The invention provides a hydraulic safety device for a two-roller calender, which is characterized in that the hydraulic safety device comprises a hydraulic cylinder (1), a sensor (2), a hydraulic system (8) and a control system (9), wherein, the hydraulic cylinder (1) is arranged below a roller bearing (10); the sensor (2) is arranged below the hydraulic cylinder (1); the sensor (2), the control system (9), the hydraulic system (8) and the hydraulic cylinder (1) are connected sequentially. The invention has simple structure, and can detect the horizontal pressure change of the roller; when the horizontal pressure exceeds a preset value, a roller automatically enlarges roller spacing through the hydraulic system, avoiding the occurrence of roller damage; when the horizontal pressure drops to a certain value, the roller automatically resets. The whole process is completed in an instant and the production line process is not affected; on the other hand, piling glue amount can be controlled by horizontal pressure detection.
Description
Technical field
The present invention relates to a kind of overload protective device of two-roll calendar roller, relate in particular to a kind of hydraulic safety device of two-roller calender.
Background technology
Calender is a widely used equipment in the rubber industry, especially the makers' key equipment of stream in tire manufacturing plant and rubber strip.Need two rollers that the material that is rolled is applied certain horizontal pressure during calender work, must install safety device protection rolling mill roller at the two ends of roller additional for preventing that roller from damaging.Because down the accumulation sizing material amount of the upper and lower roller of feeding calendering constantly changes and makes it the pressure that roller bears and change in working order thereupon, pressure is delivered on the safety device at roller two ends.Horizontal pressure will be excessive surpasses the bearing capacity of roller when spacer gel is excessive, even makes the roller fracture, and at this moment safety device will work and discharge horizontal pressure protection roller.
Traditional safety device is the safety disc mechanical structure; Between load-bearing circle and gland, adorn safety disc, dress balancer below safety disc is when owing to roller horizontal pressure overload; The mechanical type safety disc is destroyed with the protection roller, needs to shut down and change immediately new safety disc this moment; The mechanical type safety disc can play safe effect, but detects the actual pressure less than roller.Because the safety disc replacing time is long, and might cause that the long Products Quality that causes of material lagging descends on the production line, even cause equipment impaired, safety disc thickness and bursting force are very difficult controls in the mill in addition.Traditional safety device can not detect the actual pressure that bears of roller, and these problems are prevalent on the machine of domestic and imported, and never are resolved.On the one hand because rubber rolls its swell increment difference of goods of coming out under different pressures, cause the in uneven thickness of goods again, can not detect the actual pressure that bears of roller, also just can not effectively control the thickness and precision of horizontal pressure and rolled products.
Summary of the invention
The purpose of this invention is to provide a kind of actual pressure that bears that can detect roller, and then control the hydraulic safety device for two-roller calender of horizontal pressure and rolled products thickness and precision.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is:
A kind of hydraulic safety device for two-roller calender comprises hydraulic cylinder (1), sensor (2), hydraulic system (8), control system (9), said hydraulic cylinder (1) be placed in roller bearing (10) below, sensor (2) be positioned on hydraulic cylinder (1) below; Said sensor (2), control system (9), hydraulic system (8), hydraulic cylinder (1) connect successively; Roll adjustment leading screw (3) is installed below the described sensor (2); Roll adjustment leading screw (3) is connected with roll adjustment screw (5); Thrust bearing (6) and gland (4) are installed on the said roll adjustment screw (5), and roll adjustment screw (5) is connected with drive unit (7), and the bulb of said sensor (2) cooperates with the concave spherical surface of hydraulic cylinder (1); Said roll adjustment leading screw (3) and roll adjustment screw (5) are for being threaded, and said sensor (2) is the pillar LOAD CELLS.
Said hydraulic system (8) also includes magnetic valve, and the course of work of said control system is:
(1) sensor detects signal numerical value and preestablishes that setting value compares in the control system;
(2) when the signal numerical value that detects during greater than setting value, the control system sends control signal and makes the magnetic valve switching-over work in the hydraulic system, draws off the pressure oil in the hydraulic cylinder.
The invention has the beneficial effects as follows: simple in structure, the horizontal pressure that can detect roller changes, and when horizontal pressure exceeded setting value, roller widened roll spacing automatically through hydraulic system, avoided occurring the roller breakoff phenomenon; After horizontal pressure dropped to certain value, roller automatically reset.The moment completion of whole process, the production line flow process is not affected, and detects with horizontal pressure on the other hand and can control the spacer gel amount.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described further.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is control principle figure.
Among the figure: 1, hydraulic cylinder 2, sensor 3, roll adjustment leading screw 4, gland, 5 roll adjustment screws 6, thrust bearing 7, drive unit 8, hydraulic system 9, control system 10, roller bearing.
The specific embodiment
Hydraulic safety device for two-roller calender as shown in Figure 1 is made up of hydraulic cylinder 1, sensor 2, hydraulic system 8, control system 9.The last plane of hydraulic cylinder 1 holds up roller bearing 10, and the top bulb of sensor 2 pushes up in the concave spherical surface of hydraulic cylinder 1.Hydraulic cylinder 1 becomes a rigid body carrying roller and is delivered to the pressure on the bearing block after hydraulic system 8 supplies pressure oil; Sensor detects and converts the signal of telecommunication to after this power and pass back in the control system 9; Compare with the safeguard protection pressure magnitude of voltage that preestablishes in control system 9, when detect signal value be operate as normal during less than setting value, when the signal value that detects during greater than setting value control system 9 send control signal and make the magnetic valve switching-over work in the hydraulic system 8; Draw off the pressure oil in the hydraulic cylinder 1; The piston rod of hydraulic cylinder 1 shrinks, and at this moment roller bearing 10 is together withdrawn in company with the piston rod of hydraulic cylinder 1, leaves the position that produces high pressure fast; Prevent that the high pressure roller from damaging, and reaches the purpose of protection roller.Can return to normal condition after the factor of artificial eliminating generation high pressure.
As further improvement of the present invention: hydraulic safety device for two-roller calender comprises roll adjustment leading screw 3, gland 4, roll adjustment screw 5, thrust bearing 6, drive unit 7; The upper surface of roll adjustment leading screw 3 is fixedly connected with the sensor lower plane, and roll adjustment leading screw 3 is connected with roll adjustment screw 5.Thrust bearing 6 and gland 4 are installed on the roll adjustment screw 5, and roll adjustment screw 5 is connected with drive unit 7.The support force system that the formation of roll adjustment leading screw 3, roll adjustment screw 5, thrust bearing 6 is one, 5 radial locations of roll adjustment screw are pushed down and made to gland 4.During work, drive unit 7 can drive 5 rotations of roll adjustment screw.
