[0019] A handle is fixedly connected to the pressing plate 7.

[0020] A material receiving box body 24 is placed on the bottom plate 1.

[0021] The working principle of the present utility model is as follows: In the first step, the empty pressing plate is pushed into the chute of the conveying frame body. Then, control the first driving motor to drive the first lead screw to rotate. The first lead screw drives the conveying frame body and the pressing plate to move along the fixed sliding rods. When the pressing plate moves to directly below the material storage box body, control the first driving motor to stop working.

[0022] In the second step, the gunpowder powder is injected into the storage box body through the feeding channel. Then, control the electric valve to open the discharge pipe channel. At the same time, control the first electric push rod to drive the first connecting rod and the pressing plate to descend, so that the pressing plate pushes the gunpowder powder. The gunpowder powder falls into the manufacturing groove of the pressing plate through the discharge pipe. After the injection of the gunpowder powder is completed, control the electric valve to close the discharge pipe channel, and at the same time control the first electric push rod to stop working. Subsequently, control the second driving motor to drive the second lead screw to rotate, and the second lead screw adjusts the movement of the storage box body, the discharge pipe and the electric valve, so that the discharge pipe moves above the empty manufacturing groove and stops. Then repeat the above gunpowder powder injection steps until all the manufacturing grooves of the pressing plate are filled with gunpowder powder.

[0023] In the third step, after the injection of the gunpowder powder is completed, continue to control the first driving motor to drive the first lead screw to rotate, and the first lead screw drives the transporting frame body and the pressing plate to continue to move, so that the pressing plate stops moving under the scraping plate. When injecting the gunpowder powder, it is inevitable that some gunpowder powder will fall on the pressing plate. Control the second electric push rod to drive the second connecting rod and the scraping plate to move. After the scraping plate moves to the surface of the pressing plate, the scraping plate will push off the gunpowder powder, so that the gunpowder powder falls into the material collecting box body, avoiding waste of the gunpowder powder. After the gunpowder powder is pushed off, control the second electric push rod to drive the second connecting rod and the scraping plate to move in the reverse direction to reset.

[0024] In the fourth step, continue to control the first driving motor to drive the first lead screw to rotate, and the first lead screw drives the transporting frame body and the pressing plate to continue to move, so that the pressing plate stops moving under the lifting plate. Then control the third electric push rod, the third connecting rod, the lifting plate and the pressing rod to descend. After the pressing rod descends and contacts the gunpowder powder, the pressing rod presses the gunpowder powder, so that the gunpowder powder is transformed into a cylindrical medicine column. After the pressing of the gunpowder powder is completed, control the third electric push rod, the third connecting rod, the lifting plate and the pressing rod to rise to reset. Then control the first driving motor to drive the first lead screw to rotate again, and the first lead screw drives the transporting frame body and the pressing plate to move away from the lifting plate. After the first driving motor stops working, place the finished product box on the bottom plate and close to the transporting frame body, and pull the handle to extract the pressing plate from the transporting frame body. Some medicine columns will fall into the finished product box when the pressing plate is extracted, thus completing the collection of the medicine columns.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
