Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicinal slices, in particular to a Chinese medicinal slice shaping and compression device and a processing technology thereof. Background Art

[0002] Chinese herbal medicines are Chinese medicine products with certain specifications and quality standards, which are made by processing Chinese medicinal materials into slices based on the theories and processing methods of traditional Chinese medicine. Chinese herbal medicines include some Chinese herbal medicine slices processed at the place of origin, original herbal medicine slices, and slices that have been cut and processed. The first two categories are usually regarded as Chinese medicinal materials in management, but they are understood as slices when formulating and preparing. In the prior art, bulk slices are the representative of traditional slices, with a wide range of applications, long use time, high safety and good efficacy. However, their large size, easy contamination, short shelf life, inconvenient adjustment and inability to cope with critical and severe diseases have always restricted their development. In addition, granular slices are also widely used. They make traditional slices into granules of a certain size, which are packaged into agreed doses according to requirements for formulation and production of finished medicines. Their advantages are accurate dosage, high dissolution rate, reduced dosage, simple packaging, shortened decoction time and increased decoction volume. They are also easy to sterilize, store and transport, and automatically adjust. However, granular slices lack morphological identification characteristics and no longer have the natural properties of Chinese medicine slices, so they have limited market acceptance and have failed to replace bulk slices.

[0003] Therefore, the inventors designed a compressed medicinal piece, which only undergoes physical transformation on the basis of bulk medicinal pieces. It has all the advantages of bulk medicinal pieces, while reducing the volume, making it easy to standardize production and storage, and extending the shelf life. It can realize automatic adjustment, combining the advantages of traditional medicinal pieces and granular medicinal pieces, and adapting to the innovation and intelligent development of Chinese medicine medicinal pieces.

[0004] However, in the prior art, the preparation and batch production of compressed medicinal slices have always been a difficult problem. People usually use a compressor in combination with a certain mold to compress a certain amount of medicinal slices; for example, a patent with application number CN202311251218.X discloses: a weighing-free compressed medicinal slice production equipment, comprising: a workbench, the four corners of the bottom of the workbench are fixedly installed with supporting feet, an L-shaped plate is fixedly installed on one side of the top of the workbench, a hydraulic press is fixedly installed on the top of the L-shaped plate, a hydraulic base is fixedly installed at the center of the top of the workbench, the hydraulic base is arranged corresponding to the output end of the hydraulic press, a flip block is movably installed on the top of the hydraulic base, and a mold is fixedly installed on one side of the flip block; the quality of the present invention is fixed in shape, the breakage rate is reduced, and there is no air and it is not easy to be infested with insects and mold; a small number of insects and molds are also easy to find, thereby ensuring stable quality and avoiding the problem that bulk medicinal slices will collide with each other internally during transportation or storage, the degree of breakage is increased, the appearance is unstable, and due to the presence of air, the probability of insects and mold is very high, and it is not easy to find and increase management difficulty.

[0005] Although this device can realize the production of compressed medicinal slices, it has the following shortcomings: this device cannot continuously compress the raw medicinal slices, and the compressed medicinal slices must be turned over and separated after compression, and the loading must be done manually. These processes will affect the production efficiency of the compressed medicinal slices, making it inefficient and not suitable for mass production of compressed medicinal slices; at the same time, manual control of loading may cause the raw medicinal slices to spill, which will not only waste raw materials, but also affect the consistency of the quality of the compressed medicinal slices.

[0046] Embodiment 2

[0047] This example discloses a processing technology of a Chinese medicine slice shaping and compression equipment, see Figures 1 to 9 , including the following steps:

[0048] S1, first, the staff sits in the operating area on the step ladder 311, and manually places the raw medicinal pieces to be compressed in a continuous and quantitative manner in the feeding trough 33 on the feeding belt 32. There are several possibilities for the raw medicinal pieces:

[0049] 1) For special fruit and seed raw material pieces with fine particles, such as Cnidium monnieri, Plantago asiatica, Pollen Typhae, etc., the weight is directly determined after processing and placed in the material trough 33, wherein the weight is in grams per 1g;

[0050] 2) For whole herb, flower and leaf pieces with large volume and light weight, such as motherwort, selfheal, mulberry leaf, perilla leaf, etc., firstly, they are processed to have qualified properties of Chinese medicine pieces, then the qualified pieces are lightly sprayed, and the weight is determined and placed in the material trough 33, wherein the weight is in grams.

[0051] After the raw materials are placed, the equipment is started; at this time, the conveyor belt 5 is driven by the second motor 51 to rotate continuously, the third motor 76 drives the driving gear 75 to rotate intermittently, and drives the mold mechanism 4 to rotate intermittently through the driven gear 461 meshing with it, and the hydraulic press 21 drives the hydraulic rod 211 to move intermittently;

[0052] S2, then, the third motor 76 drives the mold mechanism 4 to rotate and when it rotates to the point where the movable protrusion 81 is located between the mold openings 411, it stops rotating for 1 second, and the lower end of the feeding channel 35 corresponds to the upper side of the mold opening 411 at the same time; at the same time, the movable protrusion 81 is now freed from the limit, and is pushed upward by the elastic force of the third spring 83 until the metal sheet 85 is attached to the motor switch 36, and the movable protrusion 81 is limited and fixed, and the motor switch 36 is now turned on by the metal sheet 85, the first motor 34 is started, and the feeding belt 32 is driven to rotate; the feeding trough 33 rotates accordingly, and the raw material pieces therein fall onto the feeding channel 35 during rotation, and slide into the corresponding mold opening 411 under the action of gravity;

[0053] S3, when the raw material slices are loaded into the corresponding mold opening 411, 1 second has passed, and the mold mechanism 4 continues to rotate for 1 second. At this time, the movable protrusion 81 is compressed into the movable circular groove 71 by the mold plate 41 again, and the downward displacement of the movable protrusion 81 causes the metal sheet 85 to separate from the motor switch 36. The first motor 34 stops working after power failure, and the feeding belt 32 stops rotating.

[0054] S4, during the period when the mold mechanism 4 stops rotating for 1 second, not only the feeding mechanism 3 is feeding the mold opening 411, but the compression mechanism 2 is also performing compression work at the same time. When the mold opening 411 loaded with the raw material slices rotates to just below the compression rod 23, the mold mechanism 4 stops rotating for 1 second. At this time, the hydraulic press 21 runs and drives the hydraulic rod 211 to drive the push assembly 24 to push the raised disk 42, and at the same time drives the compression rod 23 to compress the raw material slices; during the downward displacement of the push assembly 24, the push cover 243 thereon covers the raised disk 42, and pushes the raised disk 42 to fit with the base 7. During the continuous downward displacement of the push assembly 24, the compression rod 23 compresses the raw material slices in the mold opening 411 until a certain pressure value is reached. After the compression is completed, the hydraulic press 21 drives the compression rod 23 and the push assembly 24 to rise and reset. At this time, the mold mechanism 4 is canceled from the limit and resets under the push of the second spring 45. The pressure value detection and pressure value setting in this process are both prior art and will not be repeated in this technical solution. During this period, the movable protrusion 81 is synchronously canceled from the limit, and the feeding mechanism 3 is started to synchronously feed.

[0055] S5, then, the mold mechanism 4 continues to rotate for 1 second, the feeding mechanism 3 and the compression mechanism 2 stop working, and after 1 second, the mold port 411 rotates to the specified position, the mold mechanism 4 stops rotating for 1 second, and the feeding mechanism 3 and the compression mechanism 2 start to repeat the above-mentioned feeding and compression work respectively;

[0056] S6. Finally, during the rotation of the mold mechanism 4, the finished compressed medicinal slices are driven to rotate continuously until the finished compressed medicinal slices rotate to the notch on the base 7. The finished compressed medicinal slices are freed from the limit and fall onto the conveyor belt 5 under the action of gravity. The continuously rotating conveyor belt 5 drives the finished compressed medicinal slices to fall into the storage box 6, thereby completing the recovery of the finished compressed medicinal slices. When packaging the finished products, 500g or 1000g medicinal slices are packaged in a medium package, so that the dosage required for clinical use can be freely matched and the quality of the medicinal slices can be guaranteed to be stable.

[0057] By utilizing the compression equipment in the technical solution, not only can the large and light whole herb, flower and leaf pieces be effectively shaped and demolded, thereby reducing their size, stabilizing their properties, reducing losses and eliminating dust; it can also make special fruit and seed Chinese herbal medicines with fine particles easier to flow, reduce spilling and drifting; at the same time, it saves various costs in the circulation link of the pieces, and changes the large size, easy jamming, and dust-intractable dirty phenomena of the automatic preparation machines for the pieces.

[0058] The device of the present application can continuously produce compressed medicinal slices in batches, and the rotation of the active gear 75 is used to indirectly drive the mold plate 41 to rotate intermittently, so that the mold opening 411 can continuously correspond to the bottom of the compression rod 23, and the raw medicinal slices therein are continuously compressed by the compression rod 23, thereby improving the production efficiency; the device of the present application can also automatically recycle the finished compressed medicinal slices. When the finished compressed medicinal slices pass through the notch on the base 7, they fall on the conveyor belt 5 and are driven by the conveyor belt 5 to be input into the storage box 6; in order to ensure that the finished compressed medicinal slices can fall, the inner wall of the mold opening 411 can be designed as a smooth curved surface, so that the gravity of the medicinal slices themselves can be greater than the medicinal slices and the mold opening 411. The friction between the pieces makes the slices fall smoothly. The existing technology can also be used to achieve the falling of the slices. The specific method is not within the protection scope of this application, so no technical limitation is made. The device of this application also has the function of automatic feeding. The mold plate 41 cooperates with the control component 8 to indirectly drive the feeding belt 32 to rotate intermittently. During the rotation, the raw slices in the feeding trough 33 are gradually transported into the mold mouth 411 through the feeding channel 35 to achieve the purpose of automatic feeding. The device of this application is an integrated automatic equipment, which is automated from feeding to finished product recovery. The staff only needs to place the raw slices in the feeding trough 33. The operation is simple and practical. In addition, the motor operation and its control principle, the hydraulic press operation and its control principle in this technical solution are all existing technologies, and the specific working principles will not be repeated.

[0059] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
