Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine decoction pieces, and specifically to a mixing device for processing traditional Chinese medicine decoction pieces. Background Art

[0002] In the patent application with the authorization announcement number CN216756289U, it discloses a mixing device applicable to the processing of traditional Chinese medicine decoction pieces, including a fixed outer plate. One end of the surface of the fixed outer plate is provided with a protective plate frame, on the surface of the protective plate frame is provided a first motor, the output end of the first motor is provided with a first conveyor belt, the other end of the surface of the fixed outer plate is provided with a second motor, one end of the second motor is provided with a third motor, one end of the third motor is provided with a fourth motor, the top side of the surface of the fixed outer plate is provided with a pneumatic pump, the output end of the fourth motor is provided with a storage box, and the top side of the storage box is provided with a falling cover body. During the process of mixing traditional Chinese medicine, by setting the sixth motor to drive the mesh cylinder to rotate, the traditional Chinese medicine that does not meet the specifications in the mesh cylinder is stirred out. Moreover, the holes opened on the surface of the mesh cylinder are the same size as the required specification of the traditional Chinese medicine slices. After being stirred out, it leaks through the falling cover body connected to the bottom side inside the mixing cylinder and is stored in the storage box.

[0003] In the prior art including the above patent, the existing mixing of traditional Chinese medicine decoction pieces includes dry mixing and soaking mixing (soaking method). Dry mixing means taking out various required traditional Chinese medicine decoction pieces in proportion, first grinding and screening them, and then using a mixer or a manual stirrer to mix various traditional Chinese medicine decoction pieces evenly to make powder or other forms of traditional Chinese medicine preparations. This method is usually used for preparing powder, with simple operation, relatively high mixing efficiency, and can maintain the original properties of the medicinal materials. Soaking mixing (soaking method) is to take out various required traditional Chinese medicine decoction pieces in proportion, soak them in clear water for a period of time, and then carry out grinding or other treatments. This method is mainly used for the mixing of some special medicinal materials, such as medicinal materials with harder texture or difficult to directly grind. By soaking, it can be softened to facilitate subsequent grinding and mixing. At the same time, soaking also helps to dissolve the active ingredients in the medicinal materials and improve the medicinal effect.

[0004] For the existing mixing equipment, the volatile of the active ingredients in traditional Chinese medicine decoction pieces is relatively slow, and it cannot be used for both dry and soaking mixing, and there is still room for improvement in the classification and reuse of soaked traditional Chinese medicine decoction pieces.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The mixing device for processing traditional Chinese medicine decoction pieces is reasonable and has the following advantages:

[0016] The driving device drives the reciprocating screw rod structure to vertically move the pressing block to press the cloth bag into contact with the upper pressing block. Through pressing, the surface area of the traditional Chinese medicine decoction pieces increases, and the pore structure inside the traditional Chinese medicine decoction pieces also changes, which helps the active ingredients in the traditional Chinese medicine decoction pieces to dissolve and volatilize faster, thereby improving the medicinal effect, improving efficiency. Moreover, the driving device can also drive the rotating rod and the spiral blade to rotate, so as to better evenly distribute the medicinal effect in the dissolving liquid, thereby improving efficiency. Finally, when the cloth bag exits the mixing tank, the cloth bag will bring out some dissolving liquid. At this time, by controlling the extrusion of the cloth bag, the traditional Chinese medicine decoction pieces in the cloth bag can be further de-liquefied. For the dry mixing of various dry medicinal materials, the spiral blade at a 15-degree horizontal upward slope can continuously drive the dry medicinal materials at the bottom of the mixing tank to move up, and the dry medicinal materials at the upper end of the mixing tank to move down. At the same time, the feeding port can also assist in feeding, so as to evenly make the dry mixing of various dry medicinal materials uniform. By rotating the anti-loosening bolt, the anti-loosening block can be separated from the notch, so that a cloth bag connected by a plurality of sliders can be placed, and then closed, so as to ensure that the position of the cloth bag in the mixing tank is convenient for promoting the device to dissolve and volatilize the medicinal materials faster, and different varieties of traditional Chinese medicine decoction pieces can be placed in each bag, and the traditional Chinese medicine decoction pieces that can be reused after subsequent soaking and volatilization are reserved;

[0017] By driving the first gear, the second gear, and the third gear through the driving motor, the promoting device, the material leveling device, and the grinding device can be driven to operate simultaneously, improving efficiency while reducing costs. Moreover, the driving motor is connected with a torque sensor, which can set the torque resistance when the promoting device extrudes the traditional Chinese medicine decoction pieces in the cloth bag, and can capture the torque resistance situation of the driving motor in real time, perform reverse reset and then start, so as to avoid breaking the cloth bag and causing the medicinal materials in the cloth bag to escape;

[0018] When a more sufficient dissolving solution is needed to dilute traditional Chinese medicine decoction pieces, mixed dry traditional Chinese medicine decoction pieces, or for the reuse of the diluted traditional Chinese medicine decoction pieces, the medicinal materials can be put into the storage hopper for further grinding. The driving device drives the transmission block, transmission column, first grinding block, and spiral feeding blade to rotate, so that the traditional Chinese medicine decoction pieces are fed down into the space between the first grinding block and the second grinding block for crushing. Then, the crushed traditional Chinese medicine decoction pieces fall into the cloth bag on the slider along the perforations opened on the second grinding block, the inner ring of the second gear, and the leakage holes. The other end of the clamping block is clamped with the arc-shaped groove opened on the slider, so as to ensure that the opening of the cloth bag is accurately aligned and clamped with the leakage holes and will not easily come off. All the ground medicinal materials completely fall into the cloth bag. At the same time, the arc-shaped groove is also convenient for detachment. Just apply force, and it will contract to make the opening of the cloth bag separate from the position of the leakage hole, facilitating the subsequent dissolution, dilution, and grinding of the medicinal materials;

[0019] By simultaneously rotating the symmetrically arranged adjusting bolts, the storage hopper and the second grinding block can be driven to move upward, so as to adjust the distance between the first grinding block and the second grinding block, and thus adjust the required grinding degree.
