The main structure is that: both the two sides of the internal mixer are respectively provided with a driving hydro cylinder that drives a pressing block inside the internal mixer to move fast and stably. The internal mixer with the new structure has a high pressure and good adjustment precision during work; besides, the machine has a large work speed, high efficiency and good quality.
Description
Technical field:
The present utility model is the banbury that a kind of banbury of new construction, particularly rubber and plastics industry are used.
Background technology:
Existing banbury, its floating weight all are pneumatic.In the user factory of banbury, often all be that each carries out air feed with the gas banbury in factory by a concentrated air compression station.Because the restriction of conditions such as air compressor machine and supply air line, the system pressure of air compression station are difficult to surpass 0.8Mpa, system pressure does not increase, and the motive force of cylinder is just little, and like this, the strength and the speed of banbury all are very restricted.In addition, aspect the control of the pressure degree of accuracy, because of gas has this physical characteristic of compressibility, so in banbury working motion process, the numerical value that accomplish accurate controlled pressure is very difficult.Moreover using in the gas system of air compression station, a lot of with the machine of gas, the fluctuation of source of the gas is very big, and interference each other is very big.Along with the development of rubber and plastics industry, the material that banbury will be refined all was significantly improved than in the past in the requirement of a series of indexs such as hardness, viscosity, temperature, decentralization.In a word, existing banbury is difficult to satisfy current rubber, plastic article industry material is carried out high strength, high accuracy, high-speed banburying requirement.
Summary of the invention:
The utility model banbury is by banburying chamber (13), floating weight (10), form with floating weight (14), ram (12) decelerator (5) and moving electric apparatus control apparatus (6), and last bolt (10) is connected with fluid pressure type drive unit (1).
This novel banbury respectively is equipped with an oil cylinder (2) in the both sides of banburying chamber (13), and these two oil cylinders (2) are connected with ram (12) by crossbeam (4).
This novel banbury, the main valve of its control oil cylinder (2) action is proportional servo valve (7).
Description of drawings:
In the Figure of description, Fig. 1 is a front view of the present utility model, and Fig. 2 is the cutaway view in A-A cross section.
The specific embodiment:
Below in conjunction with accompanying drawing, further specify the structure of the utility model banbury.
The type of drive of floating weight (10) is a fluid pressure type, drive the operation up and down of ram (12) with fluid pressure type drive unit (1), in the both sides of banburying chamber (13) oil cylinder (2) is housed respectively, the structure of these two oil cylinders is identical, it is all the same that dimensional requirement is made, the two ends up and down of oil cylinder are radial type, so that get rid of because the error that produces in the manufacture process.The lower end of oil cylinder (2) is connected with the lower end of wallboard (9), and the jointed shaft (3) of the upper end of oil cylinder (2) is connected with crossbeam (4).
The two ends of crossbeam (4) are oil cylinder (2), and the centre of crossbeam (4) is connected with driving shaft (8).
Driving shaft (8) is that vertical ground is installed, this be complete machine at the location of vertical direction benchmark, when whole machine installation, to check this up rightness, otherwise can influence the quality that ram (12) moves up and down ground.The upper end of driving shaft (8) is connected with crossbeam (4), and the lower end is connected with ram (12).
Above the ram (12) and driving shaft (8) bottom two is to be fastenedly connected between both, all can not become flexible in the time spent of doing of various loads, so that transferring power herein.There is the slotted hole of logical cooling water at the middle part of driving shaft (8), cooling water is injected in the ram (12) by this hole, so that when taking away work, ram (12) and material are because fricative heat, contact with the inwall of wallboard (9) around the ram (12), these contact-making surfaces are the sliding friction contact, and the inwall of wallboard (9) is as track, ram (12) is as slide block, and ram (12) pumps along the inwall of wallboard (9).The speed of movement velocity and the size of strength thereof all are to be controlled by the proportional servo valve (7) that is connected with oil cylinder (2).The lower surface of ram (12) is the working face of ram, and this surface hardness is very high, and good corrosion resistance is arranged, and this face directly contacts with the material of being refined, and makes material obtain certain pressure.
The power source of floating weight of the present utility model (10) is that the fluid pressure type drive unit (1) by this machine provides oneself, and it doesn't matter with other banbury, do not resemble the banbury of pneumatic floating weight, the shared air compression station of many machines.
Advantage of the present utility model:
The advantage of this new construction banbury of the present utility model is: machine is at the pressure height of when work floating weight, and adjustable range is wide and precision that regulate is good, can carry out high strength, high accuracy, high-speed banburying processing to material.The operating rate of this banbury is fast, good product quality, efficient height.
The purpose of the utility model banbury is achieved in that
When ram (12) stops at when upper, open gallery ports (11), the material that this moment, input will be refined in banburying chamber (13) is after the end that feeds intake, shut gallery ports (11), hydraulic system (1) is injected hydraulic oil in two floating weights drive oil cylinder (2) then.And the pressure of hydraulic oil and flow are the arts demand special setting according to the refining different material.The pressure of the interior hydraulic oil of oil cylinder (2) is that the variation with given signal changes, the difference of its pressure, and it is just different that ram (12) is gone up the pressure that produces, and the suffered pressure of the material of being refined in the banburying chamber (13) is just different.In this banbury of the present utility model, each material at each constantly, can obtain the pressure an of the best.The same with control pressurer system, aspect flow-control, along with the variation of given signal, the flow of the hydraulic oil of turnover oil cylinder (2) also changes thereupon, and the speed that ram (12) moves up and down just changes thereupon.On the oil circuit at floating weight driving oil cylinder (2) turnover two ends, a pressure sensor (15) is housed respectively, when machine works, pressure sensor (15) detects in real time to oil pressure respectively, and a pressure signal that collects becomes the correspondent voltage signal, this signal feedback is in electrical control gear (6), and after carrying out control treatment with given voltage signal, again to new signal of Billy's servo valve (7) output.Proportional servo valve (7) is proceeded new adjustment according to this new given signal to pressure system, like this pressure differential at oil cylinder (2) two ends is carried out accurate closed-loop control, thereby, make the material in the banburying chamber obtain pressure accurately all the time.Because the material in the banburying chamber is to refine under the pressure condition of accurately having been controlled, so this banburying function is carried out high strength, high accuracy and high-speed banburying processing to material.
