Description
Technical field
The present invention relates to one kind to roll dry granulating machine lever constant-voltage equipment, more particularly, to rolls dry granulating machine pinch roller constant-pressure structure, belongs to field of pharmaceutical equipment.
Background technology
At present; in pharmaceutical field; often pharmaceutical preparation product, chemical products, material science product, food etc. are pelletized using dry granulation mode; so as to reach the purpose that a step prepares dry particle; it is especially prominent in the application of pharmaceutical field; dry granulation is to be well mixed the powder of medicine and auxiliary material, after being compressed into big sheet, tabular or runner shape, is ground into the method for needing size particles.Relative to the wet granulation of routine, dry granulation has many advantages:1. it is low to consume energy, it is not necessary to which particle is thermally dried;2. it is with short production cycle, without secondary granulation, can directly filling capsule, or for tabletting;3. production efficiency is high, continuous production meets the throughput requirements of various scales;4. have using the stability for improving medicine, the production of the labile drug degradable especially suitable for thermo-responsive material, chance water.
Dry granulation is different according to pressing principle, can be divided into double compression granulation and rolling process granulation, double compression granulation, also known as dry-pressing granulation, dry extrude grain, it is to be compacted solid powder in heavy-duty tabletting press first, turns into a diameter of 20-25mm piece embryo, is then broken into the particle of required granularity again.The technique has the drawback that:Unit interval output is small, low production efficiency, deficiency in economic performance, process controllability are poor, support that system is excessive, air and noise pollution are more, energy consumption is big, so seldom using pharmaceutical field at present.And rolling process granulation is then still being widely applied; rolling process is to utilize the gap between two scroll wheels of rotating speed identical; powder is pressed into the block of definite shape, its shape is decided by pinch roller surface condition with size, and a certain size particle is then broken into by granulator.Compared with double compression is pelletized, its is with the obvious advantage:Production capacity is big, process operability is strong, energy consumption is low, and 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. realize extrusion forming by setting the spacing between two pinch rollers, can so produce problems:1. operability is poor, especially for the pharmaceutical development stage, without any parameter foundation, it is easy to causes compacting not to be molded, or overmolding phenomenon occurs;2. material is wasted, it is necessary to grope pressure parameter by adjusting repeatedly;3. lose time, it is easy to because charging rate is uncoordinated, and cause pinch roller " locking " phenomenon.Further critical disadvantage is can not to ensure the inherent quality of particle, such as:1. in hardness heterogeneity in particle compactness heterogeneity, that is, particle;2. the particle diameter distribution of particle can not reappear;3. dissolution rate/release of solid pharmaceutical preparation finished product is unqualified, batch interior difference is big, differences between batches are big, poor reproducibility, final product quality can not be ensured.
In order to solve as above problem, different degrees of modification has all been done to respective dry granulating machine by equipment manufacturing enterprise, but be difficult be fully solved in particle quality problems.
The content of the invention
The technical problems to be solved by the invention are to overcome the puck design defect of existing rolling dry granulating machine, there is provided a kind of lever constant-voltage equipment reasonable in design, simple in construction, with a high credibility.
In order to solve the above technical problems, the present invention proposes technical scheme is:The rolling dry granulating machine lever constant-voltage equipment, its structure include pinch roller 1, pinch roller 2, pressurized cylinder, lever, fulcrum.1 progress coaxial rotating of pinch roller, does not occur upper and lower displacement, or left and right displacement.While pinch roller 2 carries out coaxial rotating, constant pressure is provided by pressurized cylinder, and acts on lever, upper and lower displacement, or left and right displacement occur for lever drives pinch roller 2.
Compared with prior art, the present invention has advantages below:Pressurized cylinder provides constant pressure, and acts on lever, and upper and lower displacement, or left and right displacement occur for the one of pinch roller of lever drives, voluntarily the spacing between adjustment and another pinch roller, so as to ensure that pinch roller constant pressure.Specific advantage has:1. strong operability, especially for the pharmaceutical development stage, the pressure value reached is wanted in input, ensures constant pressure, it is entirely avoided is not molded or overmolding phenomenon;2. saving material, saving the time, do not influenceed completely by charging rate, pinch roller " locking " phenomenon will not occur;3. preferably ensure that particle inherent quality, particle compactness is homogeneous;4. the particle diameter distribution of particle can reappear completely;5. the dissolution rate of solid pharmaceutical preparation finished product/release favorable reproducibility, batch interior difference is small, differences between batches are small, final product quality is completely secured.
