A guide rod 12 is slidably sleeved inside cutter 7. The guide rod 12 is fixedly connected to cabinet 1. By designing the guide rod 12, cutter 7 can be guided. A material trough 13 is slidably connected inside cabinet 1. A box 14 is fixedly connected to the right end of cabinet 1. A connecting mechanism 8 is provided on extrusion plate 15. A collection mechanism 9 is provided on box 14.

[0019] Please see Figure 1 , Figure 2 , Figure 3 The connecting mechanism 8 includes a fixed rod 81, which is fixedly connected inside the fixed base 6. A spring 82 is provided on the outside of the fixed rod 81. One end of the spring 82 is fixedly connected to the slider 83, and the other end of the spring 82 is fixedly connected to the fixed base 6. By designing the spring 82, the force of the spring 82 can be applied to the slider 83. The slider 83 is slidably sleeved on the outside of the fixed rod 81. The slider 83 is slidably connected to the fixed base 6. A spring block 84 is fixedly connected to the upper end of the slider 83. The spring block 84 is fixedly connected to the fixed base 6.

The ball bearing 85 is movably sleeved inside the groove 86. By designing the groove 86, the ball bearing 85 can roll inside the groove 86. By designing the connecting mechanism 8, it is convenient to disassemble the extrusion plate 15.

[0020] Please see Figure 1 , Figure 2 , Figure 4The collection mechanism 9 includes an air inlet 91. The air inlet 91 is fixedly connected to the left end of the housing 14 and is fixedly connected to the cabinet 1. An air pump 92 is fixedly connected inside the housing 14. A suction port 93 is provided on the top of the air pump 92, and an exhaust port 94 is provided on the right end of the air pump 92. The exhaust port 94 is fixedly connected to the housing 14. Two symmetrically distributed filter screens 95 are slidably connected inside the housing 14. A connecting rod 96 is fixedly connected between the two filter screens 95.

By designing the collection mechanism 9, the slag can be collected and processed.

[0021] The specific implementation process of this utility model is as follows: When in use, the raw material is first added into the cabinet 1 through the feed port 3, and then the cylinder 4 is started. The output end of the cylinder 4 drives the pressure plate 5 to move down. The pressure plate 5 will squeeze the material, and the material will be squeezed out from the hole of the extrusion plate 15. At the same time, the output end of the motor 10 drives the screw 11 to rotate, so that the cutter 7 makes a spiral motion and slides along the guide rod 12. The cutter 7 can cut the extruded medicine, thus completing the granulation of the medicine.

[0022] When the extrusion plate 15 needs to be replaced, simply move the extrusion plate 15 outwards. The extrusion plate 15 and the ball 85 slide relative to each other. The arc surface of the groove 86 inside the extrusion plate 15 will squeeze and push the ball 85 upwards. The ball 85 will drive the slider 83 upwards. The slider 83 can slide along the fixed rod 81 and squeeze the spring 82, which will cause the ball 85 to roll out of the groove 86 inside the extrusion plate 15. Then the extrusion plate 15 can be pulled out from the fixed seat 6, which is convenient for disassembling the extrusion plate 15 and for replacing the extrusion plate 15 with different apertures as needed, and for adjusting the granulation size.

[0023] Through the action of the air pump 92, the air pump 92 can draw air into the inside of the box 14 through the suction port 93, so that the inside of the box 14 is in a negative pressure state. Then, the air pump 92 can draw air into the inside of the cabinet 1 through the air inlet 91. During the drug granulation process, the dregs and small particles can be drawn in. The dregs will enter the box 14 with the air and fall on the surface of the filter screen 95. The filter screen 95 will filter out the dregs. The dregs will be retained on the surface of the filter screen 95, while the air will be discharged through the exhaust port 94, which will facilitate subsequent recycling and cleaning.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
