Abstract
The utility model relates to a down transmission single stamping tablet pressing machine which is a device for pressing powdery and grainy raw material into tablets. The existing up transmission single stamping machine has the problems of easy tablet contamination, larger vibration and large noise, but the utility model solves the problems. The utility model is characterized in that the main section of a driving mechanism is installed at the lower part of the tablet pressing machine, and the main section of the driving mechanism is enclosed. The driving mechanism is composed of a belt pulley, a gear, an eccentric wheel, a connecting rod, a cam, a lever, etc. A motor drives an upper and a lower stamping rods and a feeding device, and therefore, the actions such as feeding, tablet pressing and tablet delivering are completed.
Description
The utility model belongs to a kind of single-punch tablet press that powder shape raw material is pressed into the equipment, particularly a kind of lower-drive type of tablet.
Existing single-punch tablet press all is to go up driven type, and promptly the major part of transmission mechanism comprises major part, is installed in the top of tablet press machine.Its drive path is earlier with the top of transmission of power to tablet press machine, by the transmission mechanism that is installed in tablet press machine top power is passed to feeder and upper and lower jumper bar downwards again, finishes actions such as reinforced, compressing tablet, slice.In use for many years, last driven type single-punch tablet press has exposed following two shortcomings:
1, tablet is easily contaminated.All there is dust in the compressing tablet production environment, transmission mechanism is positioned at the top of tablet press machine, be difficult to be closed, can not to adhere to dust with exempting from,, be difficult for wiping and keep clean again because of parts are many, these driving members that adhered to dust are exposed to the top of tablet press machine, wherein also some often need oily movement parts be positioned at the compressing tablet district directly over, so, the phenomenon of tablet often takes place to pollute at work.This is unallowed in pharmaceutical tablet production particularly in tablet manufacturing, and concerning single-punch tablet press, this problem also is not resolved always.
2, vibration and noise are bigger.Because transmission mechanism is positioned at the top of tablet press machine, the height of tablet press machine is increased, center of gravity is improved, the stability and the vibration resistance of tablet press machine have been reduced, be exactly one of vibration source and noise source because of transmission mechanism itself again, be exposed to the top of tablet press machine, bigger vibration and noise when causing work.
The purpose of this utility model will provide a kind of and be convenient to prevent that tablet from polluting, vibration and the less novel single-punch tablet press of noise---lower-drive type single-punch tablet press during work.
The purpose of this utility model reaches by the following technical programs:
1, in general structure layout of the present utility model, with the major part of the transmission mechanism of tablet press machine, comprise major part (except that minority and driving member that the movement parts on tablet press machine top links to each other), be installed in the bottom of tablet press machine.This also is a major technique feature of the present utility model.
General structure of the present utility model can be divided into upper and lower two parts, superstructure: die holder and column are housed on plane on the support, the middle mould part of punching mould is installed at the Kong Zhongke of die holder, feeder and hopper are equipped with in the top of die holder, the upper end of column has header board to link to each other, the slide block that can slide up and down is housed on the column, a ram axle (so-called single-punch tablet press just is meant the tablet press machine that has only a ram axle) is housed on the slide block, the upper-lower position of ram axle can be regulated, and the upper plunger part of punching mould can be installed in the lower end.
Substructure comprises support and the motor, the handwheel, following to mandrel and transmission mechanism etc. that are installed on the support, and the upper-lower position towards mandrel is adjustable down, and the lower plunger part of punching mould can be installed in the upper end.Transmission mechanism comprises belt gear, gear drive, eccentric wheel (or bent axle, crank) jointed gear unit and cam lever (or pull bar) transmission mechanism etc. again.In addition, also have case, cover plate etc. these parts to be closed (component exception in addition that minority such as handwheel need be exposed to the outside) with support.
2, drive path of the present utility model is: motor is delivered to the tablet press machine bottom to power earlier by belt gear and gear drive, (these two cams also can merge into a single whole to make eccentric wheel and two cam rotations, cam can be coaxial with eccentric wheel, also can disalignment, but they must be to rotate synchronously), eccentric wheel moves up and down together with ram axle and upper plunger by the slide block on connecting rod drive tablet press machine top again, carries out powder is compacted into the action of tablet; Two cams are then by carrying out slice and reinforced action towards mandrel, lower plunger and feeder under the lever drives.
When debugging and a small amount of compressing tablet, rotate handwheel with hand, also can finish above-mentioned action by transmission mechanism.
3, compare with existing single-punch tablet press (going up the driven type single-punch tablet press), the utility model is owing to place transmission mechanism the bottom of tablet press machine, the parts on tablet press machine top are greatly reduced, so it is few to adhere to dust, also be convenient to wiping and keep clean, and directly over the compressing tablet district, do not have often to add lubricated movement parts, so the chance that causes tablet to pollute is few, suitably note in the work keeping clean, just can prevent the tablet contamination phenomenon.
Simultaneously, transmission mechanism is installed in the bottom of tablet press machine, has reduced total height, center of gravity is reduced, improved the stability and the vibration resistance of tablet press machine at tablet press machine; Again owing to transmission mechanism is enclosed in fuselage and the case, so vibration and noise during the utility model work are less.
In addition, the utility model transmits compression force by several connecting rods, thereby has improved the force-bearing situation of tablet press machine.
Below in conjunction with the embodiment shown in the accompanying drawing, do some specific descriptions again.The left side of Fig. 1 is the front view of the utility model embodiment, and the right is left view ［ in order to see the driving member in the case (20), left view has removed the panel of case (20) ］.Fig. 2 is the longitudinal sectional view (succinct for making drawing, as to omit part parts in addition such as the column that drawn on Fig. 1 and slide block on Fig. 2) of the utility model embodiment.
General structure of the present utility model can be divided into two parts up and down, top as shown in Figure 1, be on the last plane of support (1), to fixedly mount die holder (2) and column (3), the middle mould part (39) of punching mould can be installed in die holder (2) (does not draw in Fig. 1, as seen Fig. 2), feeder (4) and hopper parts such as (10) also are housed above the die holder (2), column (3) has 4, the upper end links to each other with header board (9), adorn slide block (7) on the column, slide block (7) can slide up and down along column (3), ram axle (6) is housed on the slide block (7), up-down adjustment can be come by two adjusting nuts (8) in the position of ram axle on slide block, and the upper plunger part (5) of punching mould can be installed in the lower end of ram axle (6).
