[0034] Reference Figure 1 - Figure 3 The ejection assembly includes a motor 81. The motor 81 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The output shaft of the motor 81 is fixedly connected to the turntable 82. After the motor 81 is started, it can drive the turntable 82 to rotate. The output shaft of the motor 81 is aligned with the center of the turntable 82. The upper surface of the turntable 82 is provided with a circular groove 801. There are multiple groups of circular grooves 801, which are arranged in a circular array with the center of the turntable 82 as the origin. The inner wall of the circular groove 801 is slidably connected with a moving block 84. The inner wall of the circular groove 801 is provided with a vertical groove. The bottom end of the right surface of the moving block 84 is provided with a protrusion, which is slidably connected to the inner wall of the vertical groove, and the moving block 84 can always block the vertical groove to prevent powder from infiltrating. The outer wall of the moving block 84 is in contact with the inner wall of the circular groove 801. The inner wall of the base 2 is elastically connected with a top block 86 through a compression spring 85, and the top block 86 fits with the circular groove 801.

[0035] Reference Figure 1 、 Figure 4The guide assembly includes a guide plate 91, the upper surface of the guide plate 91 is fixedly connected to a baffle 92, the lower surface of the guide plate 91 is fixedly connected to the upper surface of the base 2, the left surface of the guide plate 91 is in contact with the right surface of the turntable 82, the upper surface of the guide plate 91 is set as a slope, the lower surface of the baffle 92 is in contact with the upper surface of the turntable 82, the baffle 92 is set in an inclined shape, the left end of the baffle 92 is close to the front, and the right end is close to the back, which can ensure that the powder and tablets move along the surface of the baffle 92 and the guide plate 91.

[0036] Reference Figure 1 、 Figure 4 、 Figure 5 The collection assembly includes a collection box 101 , a drawer 103 is passed through and slidably connected to the right surface of the collection box 101 , and the inner wall of the collection box 101 is elastically connected to the partition 102 through a connecting spring 104 .

[0037] Reference Figure 1 - Figure 3 The bottom end of the injection tube 5 is set to be conical, and the output shaft of the motor 81 passes through the upper surface of the base 2. The upper surface of the base 2 is fixedly connected to a support seat 83, and an annular groove is provided on the support seat 83. The turntable 82 is rotatably connected to the upper surface of the support seat 83, and the lower surface of the turntable 82 is provided with an annular protrusion. The annular protrusion slides on the inner wall of the annular groove. The upper surface of the top block 86 is set to an arc surface, squeezing the arc surface of the top block 86, and the top block 86 will move downward. The top block 86 is inserted into the inner wall of the circular groove 801, which can lift the moving block 84. The top block 86 passes through and is slidably connected to the upper surface of the base 2. One end of the compression spring 85 is fixedly connected to the lower surface of the top block 86, and the other end of the compression spring 85 is fixedly connected to the inner wall of the bottom end of the base 2. When the top block 86 moves downward, it squeezes the compression spring 85 to generate a reaction force.

[0038] Reference Figure 1 、 Figure 4 、 Figure 5 The drawer 103 passes through and is slidably connected to the right surface of the collection box 101. A handle is fixedly connected to the right surface of the drawer 103 for easy gripping. A filter hole is provided on the upper surface of the partition 102, and the medicine powder can enter the drawer 103 through the filter hole, and the tablets will be blocked. The partition 102 is slidably connected to the inner wall of the collection box 101, and one end of the connecting spring 104 is fixedly connected to the lower surface of the partition 102, and the other end of the connecting spring 104 is fixedly connected to the inner wall of the bottom end of the collection box 101. When the partition 102 moves downward, it squeezes the connecting spring 104 to generate a reaction force. When squeezed by external force, the partition 102 will shake longitudinally under the action of the connecting spring 104 to avoid medicine powder residue.

[0039] Working principle: When the device is used, the powder raw material is first put into the feed bin 4, and then the motor 81 is started to drive the turntable 82 to rotate. When the circular groove 801 rotates to just below the injection tube 5, the valve 6 will automatically open to inject the powder into the circular groove 801. After the injection is completed, the turntable 82 will continue to rotate. When the circular groove 801 rotates to just below the electric pressure rod 7, the electric pressure rod 7 will press downward. With the cooperation of the electric pressure rod 7 and the moving block 84, the powder can be pressed into tablets. Driven by the motor 81, the turntable 82 will continue to rotate. When the circular groove 801 and the top block 86 are aligned, the reaction force of the compression spring 85 will push the top block 86 to move upward. The upward moving top block 86 will push the moving block 84 to move upward to eject the tablets. Since the baffle 92 and the top block 86 are close to each other, the ejected tablets will be blocked by the baffle 92 and then enter the collection box 101 along the inclined surface of the baffle 92 and the guide plate 91.

[0040] Since the device is in continuous operation, the formed tablets and excess powder will continuously enter the collection box 101 along the inclined surfaces of the baffle 92 and the guide plate 91, and the powder will enter the drawer 103 through the filter holes on the collection box 101. The tablets will be blocked on the partition 102 and can be collected in a classified manner. After the tablet pressing is completed, the device is closed and the partition 102 is pressed downward to squeeze the connecting spring 104 to generate a reaction force. Under the influence of the reaction force of the connecting spring 104, the partition 102 will vibrate back and forth longitudinally, thereby shaking off the excess powder, and then collecting the tablets on the partition 102 and the powder in the drawer 103.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
