Abstract
The utility model discloses a punching mechanism with a damping function of a single-punch tablet press. The punching mechanism comprises a base and a middle die; an upper punch and a lower punch, which can enter and exit the middle die and reciprocate along the vertical direction, are arranged in the middle die; the upper punch is mounted on a pressure adjuster; the lower punch is mounted on a tablet outlet adjuster mounted on the base; and the punching mechanism is characterized in that a damping spring is arranged between the lower punch and the tablet outlet adjuster. The punching mechanism with the damping function of the single-punch tablet press can effectively avoid the overlarge pressure of the upper punch, when the upper punch is exceedingly pressed in one direction, the punching can be reduced by the damping spring to avoid tablet cracking, the punching quality of medicine tablets can be improved, the structure is simple and the stress is uniform.
Description
Technical field
The utility model relates to a kind of pharmaceutical equipment, relates in particular to a kind of punching mechanism with single-punch tablet press of shock-absorbing function.
Background technology
Existing single-punch tablet press is all to use a threephase asynchronous machine as power source, use gear drive and cam drive to carry out the transmission of power, it specifically is equipped with an eccentric wheel and two cams on a main shaft, eccentric wheel is connected with upper punch with connecting rod by eccentric bushing, formed slider-crank mechanism, control the up-downgoing of upper punch, during compacting, produce principal pressure; Two cams are connected with undershoot with feeder respectively by connecting rod, control feeder and undershoot and complete reinforced and slice.The parameters such as the maximum pressure of pressing process, slice height and charging quantity, need pressure regulator, slice height adjuster and charging quantity adjuster on the manual adjustments tablet press machine to adjust, to adapt to the compacting needs of different tablets.
Batching granulating process before compressing tablet has a great impact compressing tablet.The situation (ratio of the situation of powder, particle degree of tightness, powder, water content etc.) of granulating as the formula of the auxiliary materials such as spice and lubricating substance, filler, binding agent, traditional tablet press machine is in the compressing tablet process, because given force value is invariable, the unidirectional pressurization of upper punch, and easily produce the shortcomings such as sliver, medicinal powder accumulation, all directly affect the tablet quality, even damage machine.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure with regard to being in order to address the above problem, the stressed punching mechanism that has uniformly the single-punch tablet press of shock-absorbing function.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises pedestal and middle mould, in described middle mould, be provided with upper punch and low punch that in passing in and out, mould also vertically moves back and forth, described upper punch is installed on pressure regulator, described low punch is installed on the slice adjuster, described slice adjuster is arranged on described pedestal, is provided with damping spring between described low punch and described slice adjuster.
Particularly, described damping spring is helical spring or elasticity of plastics post spring.
The beneficial effects of the utility model are:
The utility model can be avoided the excessive situation of upper punch pressure effectively, when the unidirectional pressurization of upper punch is excessive, can reduce punching press by damping spring, avoids sliver, improves the compacting quality of tablet, simple in structure, stressed even.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-pressure regulator, 2-upper punch, 3-low punch, 4-damping spring, 5-slice adjuster, mould in 6-, 7-feeder, 8-pedestal.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model comprises pedestal 8 and middle mould 6, in middle mould 6, be provided with upper punch 2 and low punch 3 that in passing in and out, mould 6 also vertically moves back and forth, upper punch 2 is installed on pressure regulator 1, low punch 2 is installed on the slice adjuster, the slice adjuster is arranged on pedestal, is provided with damping spring 4 between low punch and slice adjuster, and damping spring 4 is helical spring or elasticity of plastics post spring.
As shown in Figure 1, the height that slice adjuster 5 lifts when regulating low punch 3 slice, make just equal with the upper limb of middle mould 6; Pressure regulator 1 is the degree of depth descended be used to regulating upper punch 2, and descending depth is large, the near distance between between upper punch 2 and low punch 3, and pressure is large, otherwise little.
Operation principle of the present utility model is as follows:
As shown in Figure 1, in low punch 3, mould 6 lower ends enter middle nib, utilize feeder 7 to fill medicine in middle nib, upper punch 2 therefrom nib upper end enters middle nib, and descending certain distance, if upper punch 2 stamping pressures are excessive, the damping spring 4 that is arranged at low punch 3 belows can the too much stamping pressure of automatic absorption, avoids the situation of sliver to occur, and upper punch 2 portals subsequently, low punch 3 rises tablet is ejected to middle nib, completes the compressing tablet process No. one time; Undershoot drops to original position, prepares to fill again.
Above-mentioned explanation is not limitation of the present invention, and the present invention also is not limited in above-mentioned giving an example, and those skilled in the art make in essential scope of the present invention variation, remodeling, interpolation or replacement, also should belong to protection scope of the present invention.
Claims (2)
