Description
Technical field
The utility model is related to a kind of rolling dry granulating machine self-induction taper feeding structures, more particularly, to roll dry method
Granulator feeding structure, belongs to field of pharmaceutical equipment.
Background technology
At present, in pharmaceutical field, rolling dry granulation mode is often used to pharmaceutical preparation product, chemical products, material
Material science product, food etc. are pelletized, so as to achieve the purpose that a step prepares dry particle, pharmaceutical field application particularly
Prominent, rolling dry granulation is to be uniformly mixed the powder of drug and auxiliary material, after being compressed into big sheet, plate or runner shape, powder
Being broken into needs the method for size particles.Compared with conventional wet granulation, rolling dry granulation has many advantages：1. it is low to consume energy,
Further heat drying need not be carried out to particle；2. it is with short production cycle, granulation again need not be carried out, it can be directly filling
Capsule or for tabletting；3. production efficiency is high, continuous production meets the throughput requirements of various scales；Raising is utilized 4. having
The stability of drug, the production of the labile drug degradable especially suitable for thermo-responsive material, chance water.
It is different according to pressing principle to roll dry granulation, double compression granulation and rolling process granulation, weight legal system can be divided into
Grain, also known as dry-pressing granulation, it is dry extrude grain, be by solid powder first heavy-duty tabletting press be compacted, become a diameter of 20-25mm's
Then piece embryo is broken into the particle of required granularity again.The technique has the drawback that：Unit interval output is small, production efficiency
Low, deficiency in economic performance, process controllability are poor, support that system is excessive, air and noise pollution are more, energy consumption is big, so at present seldom
Use pharmaceutical field.And rolling process granulation is then still being widely applied, rolling process be using identical two scroll wheels of rotating speed it
Between gap, powder is pressed into the block of definite shape, shape is decided by pinch roller surface condition with size, then passes through
Granulator is broken into a certain size particle.It is with the obvious advantage compared with double compression is pelletized：Production capacity is big, technique is operable
Property it is strong, low energy consumption, pollution is few, has obtained quite being widely applied in pharmaceutical field.
At present, rolling dry granulating machine both domestic and external, however it remains design defect, i.e. feed section is not taper, and
Do not sense feedback fraction, can so generate 1. poor fluidity material it is more difficult carry out rolling dry granulation, even if using rolling
Dry granulation, obtained particle is also inhomogenous there are compactness, the problem of poor reproducibility；2. feeding precompressed is not formed,
Grain is inadequate in interior hardness；3. it is uncoordinated to easily cause feeding, " locking ", " asphyxia by external pressure on the chest and abdomen ", " card machine " phenomenon is caused to occur.
In order to solve the problems, such as above, different degrees of repair all has been done to respective rolling dry granulating machine by equipment manufacturing enterprise
Decorations, but the essential problem uncoordinated there is no rolling dry granulation feeding is changed.
The content of the invention
Technical problem to be solved in the utility model is to overcome the feeding of existing rolling dry granulating machine is uncoordinated to lack
It falls into, provides a kind of design reasonable, simple in structure, with a high credibility self-induction taper feeding structure.
In order to solve the above technical problems, the utility model proposes technical solutions to be：The rolling dry granulating machine self-induction is bored
Feeding structure is spent, structure includes motor part（1）, taper screw（2）, taper barrel chamber（3）, sensing feedback fraction（4）, wherein
Sense feedback fraction（4）It is connected to motor part（1）And taper screw（2）Between, motor part（1）For taper screw（2）It carries
For transmitting power, feedback fraction is sensed（4）Sense the resistance of front end feeding, and feed back to the motor part of rear end connection（1）, do
Go out speed-raising, reduction of speed or stopping action.
Motor part（1）It can be by one, two or more motor forms.
Taper screw（2）With taper barrel chamber（3）, for taper small-caliber end close to pinch roller, taper heavy caliber end leans on near-induction anti-
Present part（4）.
Sense feedback fraction（4）Be by torsional output device either current output device or power output device and
Control system forms.
Compared with prior art, the utility model has the following advantages：Motor part（1）Material conveying power, cone are provided
Spend screw rod（2）It has feeding, exhaust, pre-pressing function concurrently, senses feedback fraction（4）Output torque or electric current or power or other
Signal, feeds back to control system, and control system voluntarily adjusts feeding motor according to the size of actual signal（1）Rotating speed.Specifically
Advantage has：1. material accommodation is wider；2. collect feeding, exhaust, the taper feed section of pre- consolidation, ensure particle in
Stable quality；3. monitoring and feedback signal in real time, and feeding rotating speed is adjusted in real time, reach feeding and coordinate with pinch roller, avoid completely
" locking ", " asphyxia by external pressure on the chest and abdomen ", " card machine " phenomenon.
