Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a grinding device for producing pharmaceutical preparations. Background Art

[0002] Pharmaceutical preparations are actually finished drugs prepared in a certain form. With the development of society, in addition to decoctions, pharmaceutical preparations also include medicinal wine, koji, pills, powders, pastes, and pills. In the production process of pharmaceutical preparations, it is inevitable to clean, dry, and grind the medicinal materials. In the process of grinding medicinal materials, it is often achieved through grinding equipment.

[0003] During use, the existing medicinal material grinding device mainly drives the hammer to rotate through a motor to grind the medicinal material into powder. The medicinal material needs to be air-dried to remove moisture inside the medicinal material before grinding. However, in order to exert the medicinal properties of the medicinal material, the degree of drying of each medicinal material is different. Some medicinal materials need to be completely dried, while others need to retain some moisture. After being ground into powder, these medicinal materials with moisture will stick to the hammer due to the presence of moisture, thereby affecting the efficiency of medicinal material grinding. Utility Model Content

[0004] In view of the shortcomings of existing grinding devices, the utility model provides a grinding device for producing pharmaceutical preparations, which has the advantages of preventing medicinal material powder from adhering to the grinding hammer and improving the medicinal material grinding efficiency, and solves the technical problems of medicinal material powder adhering to the grinding hammer and low grinding efficiency.

[0005] The utility model provides the following technical solution: a grinding device for producing a pharmaceutical preparation, comprising a grinding cylinder, and also comprising:

[0006] A feed inlet is arranged in the middle of the top surface of the grinding cylinder, a motor is fixedly installed in the middle of the bottom surface of the inner cavity of the grinding cylinder, and a rotating shaft is fixedly connected to the output end of the motor;

[0007] The grinding hammer is fixedly connected to the top end of the rotating shaft, a partition is fixedly sleeved on the lower part of the outer surface of the rotating shaft, and a discharge pipe is fixedly arranged inside the side wall of the grinding cylinder at the lowest point of the partition.

[0008] Preferably, the rotating shaft includes:

[0009] A reciprocating thread is provided on the outer surface of the rotating shaft and is located on the upper side of the partition;

[0010] A magnetic pressure plate, the transmission sleeve is connected to the outer surface of the rotating shaft and is located at the reciprocating thread;

[0011] The air bag is fixedly connected to the top surface of the magnetic pressure plate and is located outside the rotating shaft.

[0012] Preferably, the grinding hammer comprises:

[0013] A sleeve, fixedly connected to the bottom surface of the grinding hammer;

[0014] An air outlet groove is provided inside the grinding hammer;

[0015] The outer surface of the magnetic pressure plate is in sliding contact with the inner wall of the sleeve, the top surface of the airbag is fixedly connected to the bottom surface of the hammer, the lower opening of the air outlet groove is connected to the airbag, and the upper opening of the air outlet groove is located on the upper surface of the hammer.

[0016] Preferably, the interior of the grinding hammer includes:

[0017] An active cavity is provided inside the grinding hammer;

[0018] A fixed shaft is fixedly connected inside the movable cavity.

[0019] Preferably, the fixed shaft includes:

[0020] A deflection plate movably sleeved on the outer surface of the fixed shaft;

[0021] The striking block is fixedly connected to the top surface of one end of the deflection plate close to the outer surface of the grinding hammer.

[0022] Preferably, the deflection plate comprises:

[0023] A magnetic block, fixedly arranged inside the end of the deflection plate away from the striking block;

[0024] A spring, fixedly connected to the bottom surface of the deflection plate located on the lower side of the striking block, wherein the bottom end of the spring is fixedly connected to the bottom surface of the active cavity;

[0025] The magnetism of the magnetic block is opposite to that of the magnetic pressure plate, and the magnetic pressure plate is within the magnetic field range of the magnetic block when it moves to the uppermost stroke.

[0026] Compared with the prior art, the utility model has the following beneficial effects:

[0027] 1. Through the reciprocating thread, magnetic pressure plate, air bag, sleeve and air outlet groove, when the motor drives the hammer to rotate and grind the medicinal materials, the rotating shaft rotates and the reciprocating thread on the rotating shaft is used to cause the magnetic pressure plate to reciprocate up and down in the sleeve. When the magnetic pressure plate moves up, the magnetic pressure plate will squeeze the air bag, so that the gas inside the air bag will be discharged through the air outlet groove. Since the exhaust port of the air outlet groove is on the outer surface of the hammer, and the air outlet groove is designed along the inclination of the outer surface of the hammer, the gas will blow the medicinal material powder on the hammer to the bottom of the hammer when it is discharged through the air outlet groove, so as to prevent the medicinal material powder from accumulating on the hammer and causing blockage.

[0028] 2. By designing the magnetic pressure plate, movable cavity, fixed shaft, deflection plate and striking block, when the magnetic pressure plate is driven by the reciprocating thread to move up to the uppermost side, the magnetic pressure plate adsorbs the magnetic block, causing the deflection plate to deflect along the fixed shaft, causing the striking block on the deflection plate to contact the side wall of the movable cavity. As the magnetic pressure plate moves downward, the deflection plate will be reset by the potential energy of the spring. At this time, the deflection plate will be continuously deflected up and down inside the movable cavity by the potential energy release of the spring, causing the striking block on the deflection plate to continuously hit the side wall of the movable cavity, thereby causing the grinding hammer to vibrate, and the vibration of the grinding hammer is used to cause the medicinal powder adhering to the grinding hammer to fall off, thereby improving the grinding efficiency of the equipment.

[0037] See also Figure 1-Figure 5 The outer surface of the rotating shaft 4 is located on the upper side of the partition 6 and is provided with a reciprocating thread 41. The outer surface of the rotating shaft 4 is located at the reciprocating thread 41 and is connected to a magnetic pressure plate 42 via a transmission sleeve, ensuring that when the rotating shaft 4 rotates, the reciprocating thread 41 drives the magnetic pressure plate 42 to reciprocate up and down. The top surface of the magnetic pressure plate 42 is located on the outer side of the rotating shaft 4 and is fixedly connected to an air bag 43, ensuring that the magnetic pressure plate 42 can squeeze the air bag 43 when it moves upward.

[0038] See also Figure 1-Figure 5 A sleeve 51 is fixedly welded to the bottom surface of the hammer 5, an air outlet groove 52 is opened inside the hammer 5, the outer surface of the magnetic pressure plate 42 is in sliding contact with the inner wall of the sleeve 51, the top surface of the air bag 43 is fixedly connected to the bottom surface of the hammer 5, the lower opening of the air outlet groove 52 is connected to the air bag 43, and the upper opening of the air outlet groove 52 is located on the upper surface of the hammer 5, ensuring that after the air bag 43 is squeezed, the gas inside the air bag 43 will be discharged through the air outlet groove 52, thereby blowing away the medicinal material powder on the hammer 5.

[0039] See also Figure 1-Figure 5 A movable cavity 53 is provided inside the grinding hammer 5 , and a fixed shaft 54 ​​is fixedly welded inside the movable cavity 53 .

[0040] See also Figure 1-Figure 5 A deflection plate 55 is movably sleeved on the outer surface of the fixed shaft 54 ​​to facilitate the deflection of the deflection plate 55 along the outer surface of the fixed shaft 54. A striking block 56 is fixedly welded on the top surface of one end of the deflection plate 55 close to the outer surface of the grinding hammer 5, which is used to strike the side wall of the movable cavity 53 to cause the grinding hammer 5 to vibrate.

[0042] The magnetism of the magnetic block 57 is opposite to that of the magnetic pressure plate 42. When the magnetic pressure plate 42 moves to the uppermost stroke, it is within the magnetic field range of the magnetic block 57, so that the magnetic pressure plate 42 can adsorb the magnetic block 57 when it moves to the uppermost side, causing the deflection plate 55 to deflect.

[0043] Working principle: When the medicinal materials need to be ground, the medicinal materials are placed in the grinding cylinder 1 through the feed port 2, and then the motor 3 is turned on. The motor 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the grinding hammer 5 to rotate. The rotating grinding hammer 5 is used to grind the medicinal materials. As the rotating shaft 4 rotates, the reciprocating thread 41 on the rotating shaft 4 is used to cause the magnetic pressure plate 42 to reciprocate up and down in the sleeve 51. When the magnetic pressure plate 42 moves up, the magnetic pressure plate 42 will squeeze the air bag 43, causing the gas inside the air bag 43 to be discharged through the air outlet groove 52, so that when the gas in the air bag 43 is discharged through the air outlet groove 52, it will be blown to the lower side of the grinding hammer 5 through the medicinal material powder on the grinding hammer 5 to prevent blockage. Secondly, the magnetic pressure plate 42 When the plate 42 is brought to the uppermost stroke by the reciprocating thread 41, the magnetic pressure plate 42 will absorb the magnetic block 57 in the deflection plate 55, so that the deflection plate 55 will deflect along the fixed shaft 54, and at this time, the striking block 56 on the deflection plate 55 will contact the side wall of the active cavity 53. When the magnetic pressure plate 42 moves downward, the deflection plate 55 will be reset by the potential energy of the spring 58. At the same time, the deflection plate 55 will be driven by the potential energy of the spring 58 to continuously deflect up and down, so that the striking block on the deflection plate 55 continuously hits the side wall of the active cavity 53, causing the grinding hammer 5 to vibrate, thereby causing the medicinal material powder adhering to the grinding hammer 5 to fall off through the vibration of the grinding hammer 5, thereby preventing the medicinal material from adhering to the grinding hammer 5 and affecting the grinding efficiency.
