Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

The scraping device provided by the embodiment of the present invention is described with reference to fig. 1 to 2, which includes a mold disc 10, wherein the axial position of the bottom end is fixedly connected with the top end of a rotating gear 61;

the bottom end of the scraping plate 30 is attached to the upper end of the die disc 10, and a stress inductor 40 is attached to the surface of the scraping plate 30; the tablet powder is fed to the die disc 10 through the feeding assembly 20, and along with the rotation of the die disc 10, the tablet powder flows into the die holes 12 of the die disc 10, but a large amount of tablet powder is remained outside the die holes 12 on the surface of the die disc 10, so that the tablet powder is scraped into the die holes 12 through the adhesion of the scraping plate 30 and the surface of the die disc 10, and the flatness of the tablet powder in the die holes 12 is flattened during the later tabletting.

When scraping plate 30 is engaged with the upper surface of mold disc 10, a certain amount of shear force is generated in scraping plate 30, and stress sensor 40 mainly senses the magnitude of the shear force.

The output end of the cylinder 70 is provided with a vertically upward telescopic rod 71, and the telescopic end of the telescopic rod 71 is vertically fixed with one side of the scraping plate 30; when scraping board 30 and mould dish 10 surface laminating, strike off the tablet powder because of long-time laminating, strike off the gap that the one end of board 30 and the laminating of mould dish 10 can produce the running-in, strike off board 30 and the laminating of mould dish 10 and will guarantee not have the gap, just can guarantee to strike off the tablet powder to the nib 12 in, consequently start telescopic link 71 through cylinder 70, will strike off board 30 and mould dish 10 and realize laminating once more.

The rotating motor 50 is arranged at one side of the base 60, the output end of the rotating motor is connected with the transmission gear 51, the transmission gear 51 is meshed with the rotating gear 61, the rotating motor 50 drives the transmission gear 51, and the transmission gear 51 drives the rotating wheel 61 to rotate.

And a controller for receiving the signal from the stress sensor 40 and driving the rotation motor 50 and the air cylinder 70.

As the shear force diminishes, the stress sensor 40 receives a signal and transmits it to the controller, which will activate the cylinder 70 to expand and contract.

In some embodiments, the upper end of the base 60 is coupled to the rotation gear 61 through a bearing.

In some embodiments, the feed assembly 20 is disposed on one side of the die plate 10.

In some embodiments, two concentric retaining rings 11 are perpendicularly attached to the upper surface of the mold plate 10, the radii of the two retaining rings 11 are different, a plurality of mold holes 12 with the same interval are arranged between the radius difference of the two retaining rings 11, and the plurality of mold holes 12 are arranged along the circumferential direction.
