A kind of high speed tablet press
Technical field
The utility model relates to a kind of pharmaceutical equipments, more particularly to a kind of tablet press machine.
Background technique
High speed tablet press because can quickly be widely used in slugging, but to moist stronger material, especially
Chinese patent medicine particles with medicinal extract, tabletting are difficult to complete.First is that the material moisture absorption in hopper is very fast, cause material plate form block at
Group, mobility is poor, and slice weight fluctuation range causes greatly tablet weight variation unqualified, high rejection rate, and rework cost is higher;Second is that in phase
To in closed tabletting room, material enters die hole through powder-scraper, forms under upper punching and the compacting of undershoot, material is adhered to because of the moisture absorption
On powder-scraper, cause to scrape that powder is uneven, and tablet weight variation is unqualified;Object third is that material compression moulding in die hole, after the moisture absorption
Material under the effect of external force, be adhered in lower punch and middle die hole and do not fall off, cause the piece appearance of compression moulding have cap off,
Surface irregularity, appearance character are unqualified etc., must shut down comprehensively cleared up at this time;Fourth is that because material sticks are upper and lower
The surface of punch die causes the pressure of normal pressing process to increase, and tablet hardness increases, the risk and punch die bar that disintegration time limited lengthens
The risk that damage or even punch die bar fracture, it is very big to the damage destruction of equipment, it is costly caused by more mold exchange.Before facing
Problem is stated, existing processing method includes 1, carries out drying and processing to the material of the moisture absorption;The upper lower punch of 2 pairs of tablet press machines is in
Mould carries out cleaning treatment and polishing treatment.But cause the loss of material larger in this way, the contaminated risk with cross contamination of material
Higher, quality risk is big.
Therefore those skilled in the art be dedicated to developing it is a kind of do not influenced by ambient humidity, tablet quality is high, it is high-efficient, at
The high speed tablet press of this low reduction labor intensity of workers.
Utility model content
In view of the above drawbacks of the prior art, the technical problem to be solved by the utility model is to provide one kind not by ring
Border humidity influences, tablet quality high speed tablet press that is high, high-efficient, at low cost, reducing labor intensity of workers.
To achieve the above object, the utility model provides a kind of high speed tablet press, including tabletting room, and the tabletting room is set
It is equipped with wind pipe, the air inlet of the wind pipe connection dehumidifier, the air outlet of the dehumidifier is connected to the tabletting
The intake stack of room;
Humidity sensor is provided in the tabletting room, the humidity sensor and dehumidifier electrically connect with PLC controller
It connects.
Preferably, being respectively arranged with first filter and the second filter on the wind pipe and intake stack.
Preferably, the hopper for protruding into the tabletting room is wrapped with the interior stainless sheet steel with resistive heater.
Preferably, the first filter is filter screen.
Preferably, being provided with temperature sensor, the temperature sensor and the resistive heater on the hopper inner wall
It is electrically connected with PLC controller.
Preferably, the wind pipe is set on the bottom of the tabletting room;The intake stack leads to the tabletting room
Top.
Preferably, the dehumidifier is set to the tabletting motor spindle.
The beneficial effects of the utility model are: the utility model tabletting effect is good, high production efficiency is wasted less, is produced into
This low, durable, reduction labor intensity of workers.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of one specific embodiment of the utility model.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples, it should be noted that, in the description of the present invention,
The orientation or positional relationship of the instructions such as term " on ", "lower" is to be based on the orientation or positional relationship shown in the drawings, merely to just
In description the present invention and simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with
Specific mode is constructed and is operated, therefore is not considered as limiting the invention.Term " first ", " second " etc. are only used for retouching
Purpose is stated, relative importance is not understood to indicate or imply.
As shown in Figure 1, a kind of high speed tablet press, including tabletting room 1, tabletting room 1 are provided with wind pipe 3, wind pipe 3
The air inlet of dehumidifier 4 is connected, the air outlet of dehumidifier 4 is connected to the intake stack 8 of tabletting room 1.Wind pipe 3 is set to pressure
On 1 bottom of piece room, intake stack 8 leads to 1 top of tabletting room.Dehumidifier 4 is set to tabletting motor spindle.
First filter 31 and the second filter 81 are respectively arranged on wind pipe 3 and intake stack 8.Present embodiment
Middle first filter 31 is filter screen.
It is provided with humidity sensor 5, humidity sensor 5 and dehumidifier 4 in tabletting room 1 and PLC controller 10 is electrically connected.
High speed tablet press is provided with hopper 6, and the hopper 6 for protruding into tabletting room 1, which is wrapped with interior band resistive heater, (does not scheme
Show) stainless sheet steel 11.It is provided with temperature sensor 7, temperature sensor 7 and resistive heater on 6 inner wall of hopper and PLC is controlled
Device 10 processed is electrically connected.
The disposable type PLC controller for being able to achieve its function, the present embodiment can be used in PLC controller in the utility model
In, using the PLC controller of TPC12-12TD model.
When utility model works, optimal humidity and temperature can be set in PLC controller 10 in advance, material is through expecting
When bucket 6 is transported to die hole (not shown), PLC controller 10 can control resistive heater to heat the material in hopper 6, make
It is maintained at certain temperature range inside hopper 6, so that it is too fast so that the material in hopper 6 is unlikely to moisture absorption, keeps its relatively dry.
Further, inside tabletting room 1, under the induction and control of humidity sensor 5 and PLC controller 10, dehumidifier 4 can be with wet
Degree variation adjustment removes wet strength, to make humid control in tabletting room 1 in a certain range.First filter 31 makes dehumidifier
4 is not damaged, and the use of the second filter 81 can ensure that the environment in tabletting room 1 is not contaminated and cross contamination.From upper termination
Entering intake stack 8 keeps clean air wind speed slow, does not generate to the material in tabletting room 1 and any influence such as flies upward
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, it all should be within the scope of protection determined by the claims.
