Abstract
The utility model discloses a charging tabletting device for a single-punch tablet press. The charging tabletting device comprises an upper plunger (1), a lower plunger (2), a middle die (3) and a feeder (4), wherein the middle die (3) is provided with a die hole which runs through the upper and lower end faces of the middle die (3); the upper plunger (1) is arranged above the die hole of the middle die (3); the upper end of the lower plunger (2) is embedded into the die hole and seals the opening at the lower end of the die hole; the feeder (4) is arranged above the die hole of the middle die (3); the lower end face of the feeder (4) is provided with a material leakage opening (43), and the side wall of the feeder (4) is connected with a material scraping plate (41) which contacts the upper end face of the middle die (3). Due to the adoption of the structure, the charging tabletting device has a simple integral structure, and is convenient to implement; and by the charging tabletting device, the contact area of the feeder (4) and the upper end face of the middle die (3) can be reduced, and granular raw materials are prevented from being compacted on the upper face of the middle die (3), so that the horizontal position of granular raw materials which are positioned above the die hole and scraped by the feeder (4) is consistent, and the large weight difference among produced tablets is avoided.
Description
Technical field
The utility model relates to tablet press machine, specifically is the reinforced preforming device that is used for single-punch tablet press.
Background technology
Tablet press machine is widely used in fields such as medicine, food, material, and it is a kind of machine that various particles or powder stock is pressed into circular piece or special-shaped sheet.Single-punch tablet press is a kind of as tablet press machine, and it can be used for hand, because of it has only a secondary punch die, so be called single-punch tablet press.Single-punch tablet press is the machine of the electronic continuous compressing tablet of a kind of small desk; The tablet of its extrusion has the glossiness height, need not advantages such as polishing; And the depth of fill of material, the equal scalable of compressing tablet thickness, therefore; When the small lot feed particulate material was pressed into tablet, the application of single-punch tablet press was very extensive.
For the weight difference of the tablet that reduces to produce, single-punch tablet press also need be wipeed the particulate material of nib top off through feeder after reinforced in nib.Yet the feeder of existing single-punch tablet press is when the leakage material, and it leaks the upper surface that the material end is close to middle mould; When feeder in middle mould upper surface during translation; The upper surface of mould during the part particulate material will be pressed on by feeder, so, feeder moves in the nib upper surface often that regular meeting occurs beating because of the particulate material of mould upper surface in being pressed on; Thereby influence the strickling of the particulate material of nib top, make between the tablet of producing weight inconsistent.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art; A kind of contact area that can reduce feeder and middle mould upper surface is provided; Avoid particulate material to be pressed on the upper surface of middle mould, thus the consistent reinforced preforming device that is used for single-punch tablet press of horizontal level that feeder is wipeed off the particulate material of nib top.The purpose of the utility model mainly realizes through following technical scheme: the reinforced preforming device that is used for single-punch tablet press; Comprise upper plunger, lower plunger, middle mould and feeder; Mould is provided with the nib that runs through its upper and lower end face in said; The nib of mould top during said upper plunger is arranged on, the upper end of said lower plunger embed in the nib and seal the lower ending opening of nib; The top of mould during said feeder is arranged on, the lower surface of feeder are provided with Lou material mouth, and the sidewall of feeder is connected with the material scraping plate that contacts with middle mould upper surface.
The lower end of said upper plunger and the upper end of lower plunger are equipped with the drift with nib size shape coupling, and the drift of said upper plunger is over against nib, and said lower plunger is through the lower ending opening of its drift sealing nib.The utility model is provided with drift on upper plunger and lower plunger, when particulate material is suppressed, carry out through drift, so, only needs when in pressing process, finding the drift modification drift is changed, and saves cost.
The drift of said upper plunger and lower plunger is processed by carbide alloy.Drift adopts carbide alloy to process, modification easily not, thus can prolong service life of the utility model.
The upper end of said feeder is provided with loading hopper.The purpose that the utility model is provided with loading hopper is to be convenient in feeder, feed in raw material, and can make the utility model easy to operate.
Compared with prior art; The utlity model has following advantage: the top of mould during the feeder of the utility model is arranged on; Only there is the material scraping plate that is connected with the feeder sidewall to contact with the upper surface of middle mould; So, the upper surface of mould during feeder can not be compressed on particulate material easily, feeder can be realized the particulate material above the nib is wipeed off through material scraping plate in the process of translation; The mould upper surface does not have into the particulate material of piece in the cause, and material scraping plate can not occur beating in the process of translation easily yet; The leakage material mouth of the utility model is arranged on the lower surface of feeder, and the raw material in the feeder can leak material because of deadweight, thereby is convenient to the conveying of raw material.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The pairing name of Reference numeral is called in the accompanying drawing: 1, upper plunger, 2, lower plunger, 3, middle mould, 4, feeder, 41, material scraping plate, 42, loading hopper, 43, leak material mouthful.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is done further to specify, but the embodiment of the utility model is not limited thereto.
Embodiment:
As shown in Figure 1, be used for the reinforced preforming device of single-punch tablet press, mould 3 in comprising, be arranged in mould 3 tops upper plunger 1 and feeder 4, be arranged on the lower plunger 2 of punch die 3 belows.Middle mould 3 is provided with the nib that runs through its upper and lower end face; The nib of mould 3 top during upper plunger 1 is arranged on, the lower end of upper plunger 1 is provided with the drift with nib size shape coupling, and the drift of upper plunger 1 is over against nib; The upper end of lower plunger 2 also is provided with the drift with nib size shape coupling; The upper end of lower plunger 2 embeds in the nib through its drift and seals the lower ending opening of nib, and not easy to wear because of carbide alloy, the drift of upper plunger 1 and lower plunger 2 is processed by carbide alloy.The top of mould 3 during feeder 4 is arranged on, the upper end of feeder 4 is provided with loading hopper 42, and the lower surface of feeder 4 is provided with Lou material mouth 43, and the sidewall of feeder 4 is connected with the material scraping plate 41 that contacts with middle mould 3 upper surfaces.
When being used for the reinforced preforming device work of single-punch tablet press, upper plunger 1 lifts, and feeder 4 moves on the nib, and lower plunger 2 drops to the suitable degree of depth, adds particulate material through loading hopper 42 to feeder 4, and particulate material spills and get in the nib from leaking material mouthfuls 43; Feeder 4 is when nib leaves, and material scraping plate 41 makes the particulate material in the nib parallel with the upper limb of nib; Upper plunger 1 descends, and with the particulate material tablet forming; Upper plunger 1 lifts; Lower plunger 2 rises to the position parallel with the nib top edge thereupon; Feeder 4 moved on to again on the nib and tablet is pushed open and was made tablet fall into recipient through material scraping plate 41 this moment; Lower plunger 2 descends again simultaneously, fills up particulate material in the nib again and carries out the feed second time, carries out so repeatedly.
As stated, then can well realize the utility model.
