Pressure is equipped with hydraulic fluid pressure dial gauge on station, adjusts oil pressure size according to fiber sub-wire situation, basic control 3 ~ 5.5kg it
Between.320 front end of advance and retreat cutter mechanism is fixed on front slide bearing chamber 310.
In the present invention, Manual micromatic device reaches desired for adjusting gap between movable grinding disc 314 and static cutting disk 313
Yield and fiber quality.
In the present invention, thin oil lubricating device is made of Lubricating-oil Station, cooler, high-pressure oil pipe, pressure regulator etc., front slide
Cartridge housing 319 and rear sliding bearing shell 322 solve the problems, such as the lubrication and cooling of bearing by high-pressure oil pipe access Lubricating-oil Station, dilute
Petrol station guarantees that bearing temperature does not increase equipped with the cooler of enough heat dissipation areas.
In the present invention, main motor 306 and bearing body 304 are all mounted on pedestal 307, guarantee concentricity between the two.
Working principle:
By the material of pre-processing and purification, it is sent directly into mill resolver by Compulsory feeder used with 20 ~ 30% concentration, in height
Speed rotation setting wheel effect is lower to enter mill resolver, rubbing by the mechanism of high speed rotation mill, while between fiber
Power is wiped, so that material generates amount of heat, promotes the partial lignin in material to soften, with fiber separation, significantly improves fiber
Quality.
In present embodiment, stalk fibre devillicate machine is had the advantages that
1, the high concentration materials such as the straw after rubbing silk, wheat straw, cotton stalk, reed, corn stover, blocky screenings are crushed for handling.
2, adaptable, to material wide adaptability, material length is less than the stalk and all kinds of normal pressure high consistency stocks of 50mm
It can handle.
3, few to fibre cutting, wire-dividing broom purification effect is high, improves fiber flexibility, profit degree of rising, promotes the wood in stalk
Quality and fiber separation.It is best suited for the fiber wire-dividing broom purification of the low careless class of staple fiber, intensity and leaf wood, widens paper grade (stock) fibre
Tie up raw material.
4, using reasonable technique and Machine Design, high degree of automation can access full-automation process.
5, using dedicated plate design and combination, independent thin oil lubricant and hydraulic station realize that flexible Moving plate is retreated,
Thin oil lubricant is adequately lubricated and is cooled down to main shaft bearing, and manual fine-tuning mechanism can be several micro- to being accurate between sound disk
The accurate control of rice, to guarantee the precision and evenness of fiber treatment.
