Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and particularly relates to a medicinal material crushing device for traditional Chinese medicine preparation. Background Art

[0002] In the preparation of Traditional Chinese Medicine (TCM), the pulverization of medicinal materials is a critical step. Traditional TCM pulverization equipment often uses a single pulverization method, such as directly chopping the medicinal materials with high-speed rotating blades. However, this single pulverization method has many drawbacks. First, traditional pulverization equipment often struggles to effectively pulverize certain medicinal materials with a hard texture, high fiber content, or high sugar content, such as certain rhizomes or sugar-rich fruits. This results in low pulverization efficiency and uneven particle size after pulverization, making it difficult to meet the fineness and uniformity requirements of TCM preparations. Second, during operation, the high-speed friction between the blades and the medicinal materials in traditional pulverization equipment generates a large amount of heat. This heat can damage the active ingredients in the medicinal materials. This is especially true for heat-sensitive ingredients such as volatile oils and alkaloids, where high temperatures can cause them to decompose or denature, thereby affecting the efficacy of the TCM. Furthermore, for medicinal materials with high sugar content, high temperatures can melt the sugars, causing the medicinal materials to adhere to the blades or the inner walls of the pulverization chamber, impairing pulverization efficiency and increasing equipment cleaning difficulties and maintenance costs.

[0003] Therefore, the market is in urgent need of a Chinese medicine crushing device that can efficiently and evenly crush various types of Chinese medicinal materials, effectively reduce the heat generated during the crushing process, protect the effective ingredients of the medicinal materials from damage, and has a simple structure, moderate cost, and is easy to operate and maintain. Summary of the Invention

[0004] To address the aforementioned technical issues, the present invention has designed a medicinal material pulverizing device for traditional Chinese medicine preparation. This device, through a two-stage crushing component design, achieves efficient and uniform pulverization of hard, high-fiber, or high-sugar Chinese medicines, significantly improving the pulverization efficiency and powder fineness. Furthermore, a cooling component is incorporated into the first-stage crushing component, utilizing semiconductor cooling sheets to continuously cool the conical blades. This effectively prevents high temperatures from damaging the active ingredients of the Chinese medicines and prevents high-sugar herbs from adhering to the blades due to high temperatures, thereby extending the device's service life and reducing maintenance costs.

[0005] In order to achieve the above technical effects, the present invention discloses a medicinal material crushing device for traditional Chinese medicine preparation, comprising: a primary crushing component, a secondary crushing component, and a cooling component; the primary crushing component is detachably arranged on the top of the secondary crushing component; the cooling component is fixedly arranged inside the primary crushing component;

[0007] Furthermore, the interior of the conical knife is hollow, and the cooling component is fixedly arranged inside the conical knife;

[0008] Furthermore, the crushing cup has an hourglass structure that is wide at the top and bottom and narrow in the middle;

[0009] Furthermore, the cooling component includes: a semiconductor refrigeration sheet and a fan; the semiconductor refrigeration sheet is fixedly arranged on the inner wall of the conical knife; the cooling end of the semiconductor is attached to the inner wall of the conical knife; the fan is fixedly arranged on the bottom of the conical knife;

[0010] Furthermore, an air outlet is provided at the top of the conical knife;

[0011] Furthermore, a guide blade is fixedly provided on the outer side wall of the conical knife;

[0012] Furthermore, the secondary crushing assembly includes: a crushing cup, a second motor, and a crushing knife; the second motor is fixedly arranged at the bottom of the crusher; and the crushing knife is fixedly connected to the output shaft of the second motor.

[0013] This device is equipped with two-stage crushing components, wherein the first-stage crushing component can perform preliminary crushing of Chinese herbal medicines with hard texture, high fiber content and high sugar content through the principle of extrusion; the second-stage crushing component can crush the crushed Chinese herbal medicines again to make the Chinese herbal medicine powder more delicate and uniform; in addition, a cooling component is provided inside the first-stage crushing component of the device, and the semiconductor refrigeration plate in the cooling component can continuously cool the conical knife in the first-stage crushing component to prevent the effective ingredients of the Chinese herbal medicines from being destroyed due to the high temperature of the conical knife or causing the medicinal materials with too high sugar content to adhere to the inside of the blade; the cooling end of the semiconductor refrigeration plate ensures that the conical knife will not overheat, and the heat generated by the heating end of the semiconductor refrigeration plate will be blown out of the exhaust port by the fan; in addition, the upper part of the crushing cup is wide for convenient input of Chinese herbal medicines into the device, the narrow structure in the middle is convenient for cooperating with the conical knife to crush the medicinal materials, and the wide bottom is convenient for the crushed medicinal materials to fall into the second-stage crushing component.

[0014] The beneficial effects of the present invention are:

[0015] The present invention discloses a medicinal material pulverizing device for traditional Chinese medicine preparation. First, by providing a two-stage pulverizing component, the first-stage pulverizing component can utilize the extrusion principle of a conical blade to initially pulverize hard, high-fiber, or high-sugar Chinese medicines. This initial pulverization method can effectively handle medicinal materials that are difficult for traditional pulverizing devices to handle, ensuring that the medicinal materials can smoothly enter the subsequent pulverization process. Subsequently, the second-stage pulverizing component further pulverizes the initially pulverized medicinal materials, making the resulting Chinese medicine powder more delicate and uniform, meeting the strict quality requirements of Chinese medicine preparations for medicinal material powder, thereby improving the efficacy and stability of the Chinese medicine.

[0016] Secondly, the device incorporates a cooling element within the primary crushing assembly. The semiconductor refrigeration element continuously cools the conical blades, effectively preventing damage to the active ingredients of traditional Chinese medicines due to excessive blade temperatures. This is particularly important for heat-sensitive herbs, as it maximizes their medicinal value. Furthermore, heat generated by the semiconductor refrigeration element's heating end is dissipated through the exhaust vent via a fan, preventing heat accumulation within the device and further optimizing its heat dissipation performance. This cooling design not only protects the herbs but also extends the life of the conical blades and reduces equipment maintenance costs.

[0017] Furthermore, the crushing cup adopts an hourglass structure with wide top and bottom and narrow middle, making it easier to put herbs into the container. The narrow middle portion can better cooperate with the tapered blades to improve crushing efficiency, while the wide bottom design facilitates the smooth transition of crushed herbs into the secondary crushing component, ensuring a smooth process throughout the crushing process. This structural design not only improves the crushing effect, but also reduces the loss and contamination of herbs during transportation.

[0018] In summary, the medicinal material crushing device for Chinese medicine preparation of the present invention achieves efficient and uniform crushing effect through innovative two-stage crushing design and effective cooling measures, while protecting the effective ingredients of the medicinal materials and reducing the maintenance cost of the equipment. It has a compact structure and is easy to operate. It is very suitable for promotion and application in the field of Chinese medicine preparation and can significantly improve the quality and efficiency of Chinese medicine processing.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1

[0029] The present invention discloses a medicinal material crushing device for Chinese medicine preparation, Figures 1 to 5 To achieve the above-mentioned technical effects, the present invention discloses a medicinal material pulverizing device for traditional Chinese medicine preparation, comprising: a primary crushing assembly 1, a secondary crushing assembly 2, and a cooling assembly 3. The primary crushing assembly 1 is detachably mounted on top of the secondary crushing assembly 2. This detachable design facilitates maintenance and cleaning of the device. The cooling assembly 3 is fixedly mounted within the primary crushing assembly 1 to ensure effective temperature control during the crushing process, preventing damage to the medicinal materials due to high temperatures.

[0030] The primary crushing assembly 1 comprises a conical blade 101, a crushing cup 102, a mounting base 103, and a first motor 104. The conical blade 101 is rotatably mounted within the crushing cup 102, which is fixedly mounted atop the mounting base 103. This structural arrangement ensures that the medicinal materials are thoroughly ground and cut during the crushing process. The first motor 104 is fixedly mounted at the bottom of the mounting base 103. Its output shaft is fixedly connected to the conical blade 101, providing power for its rotation and ensuring effective initial crushing of the medicinal materials.

[0031] The conical blade 101 is designed to have a hollow interior, while the cooling assembly 3 is fixedly mounted inside the conical blade 101. This design not only saves space but also improves the cooling efficiency of the cooling assembly 3, enabling it to directly cool the conical blade 101, thereby better protecting the active ingredients in the medicinal materials. The crushing cup 102 adopts a unique hourglass structure, with wider upper and lower parts and a narrower middle part. This structural design not only facilitates the input of medicinal materials, but also better cooperates with the conical blade 101 to improve crushing efficiency. It also facilitates the smooth transition of the crushed medicinal materials to the secondary crushing assembly 2.

[0032] Cooling assembly 3 is further divided into a semiconductor cooling fin 301 and a fan 302. The semiconductor cooling fin 301 is fixedly mounted on the inner wall of the conical blade 101, with its cooling end closely fitting the inner wall of the conical blade 101. It can directly absorb the heat generated by the conical blade 101 during operation, effectively reducing the temperature of the conical blade 101. The fan 302 is fixedly mounted on the bottom of the conical blade 101 and exhausts the heat generated by the heating end of the semiconductor cooling fin 301 out of the device through the exhaust port 105, further optimizing the device's heat dissipation performance.

[0033] In addition, an exhaust port 105 is specially provided on the top of the conical blade 101 to help dissipate heat. Guide blades 106 are also fixedly provided on the outer wall of the conical blade 101. These guide blades 106 can better guide the medicinal materials into the crushing area when the conical blade 101 rotates, further improving the crushing efficiency.

[0034] The secondary crushing assembly 2 comprises a pulverizing cup 201, a second motor 202, and crushing blades 203. The second motor 202 is fixedly mounted at the bottom of the pulverizer, with its output shaft fixedly connected to the crushing blades 203, powering their rotation. Through further pulverization by the secondary crushing assembly 2, the medicinal materials are ground into a finer, more uniform powder, meeting the stringent powder quality requirements of traditional Chinese medicine preparations.

[0035] The working principle and usage process of this device are as follows:

[0036] The core of the device lies in the coordinated operation of the primary crushing component 1 and the secondary crushing component 2, as well as the temperature control of the primary crushing process by the cooling component 3. During operation, medicinal materials are first placed into the crushing cup 102 of the primary crushing component 1. The hourglass structure of the crushing cup 102 allows the medicinal materials to smoothly enter the crushing area of ​​the conical blade 101. Driven by the first motor 104, the conical blade 101 rotates at high speed, and the medicinal materials are effectively guided and crushed by the guide blades 106 on its outer wall. The cooling component 3 inside the conical blade 101 plays a key role in this process: the semiconductor cooling plate 301 fits tightly against the inner wall of the conical blade 101, absorbing the heat generated by the blades during operation and preventing the active ingredients in the medicinal materials from being destroyed by high temperatures, especially for heat-sensitive ingredients and those with high sugar content. The heat generated by the heating end of the semiconductor cooling plate 301 is discharged through the exhaust vent 105 at the top of the conical blade 101 via the fan 302, ensuring a stable temperature within the device.

[0037] After primary crushing, the medicinal materials are initially pulverized into smaller particles, which then enter the secondary crushing assembly 2 through a channel at the bottom of the crushing cup 102. The crushing blades 203 in the secondary crushing assembly 2, driven by a second motor 202, further finely pulverize the pre-crushed medicinal materials. This process grinds the medicinal materials into a finer, more uniform powder that meets the stringent requirements for medicinal powders in traditional Chinese medicine preparations.

[0038] To use this device, first place the medicinal herbs into the crushing cup 102 of the primary crushing assembly 1. Because the crushing cup 102 adopts an hourglass structure, wide at the top and bottom and narrow in the middle, the herbs can be easily inserted and quickly enter the crushing area under the guidance of the guide blade 106 of the conical knife 101. After starting the device, the first motor 104 rotates the conical knife 101 to begin the initial crushing of the herbs. At this time, the cooling assembly 3 is simultaneously activated, the semiconductor cooling plate 301 cools the conical knife 101, and the fan 302 exhausts heat through the exhaust port 105, ensuring that the crushing process is carried out at an appropriate temperature.

[0039] After primary crushing, the medicinal material enters the crushing cup 201 of the secondary crushing assembly 2 through a channel at the bottom of the crushing cup 102. A second motor 202 drives the crushing blades 203 to rotate, crushing the medicinal material a second time. After two stages of crushing, the medicinal material is ground into a fine and uniform powder, which is finally discharged from the device's discharge port, completing the entire crushing process.

[0040] Throughout use, users can flexibly adjust the operating parameters of the primary and secondary crushing components 2, such as motor speed, based on the properties of the medicinal materials and the crushing requirements, to achieve the desired crushing effect. Furthermore, the device's detachable design facilitates cleaning and maintenance of components such as the crushing cup 102 and conical blades 101, ensuring long-term stable operation of the device.

[0041] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all details in detail, nor do they limit the invention to only the specific implementation methods described.
