A nanoscale grinder for glabridin

Abstract

The application discloses a nanometer grinder for glabridin, and relates to the technical field of glabridin grinding, which comprises a material spraying device, a collision grinding device, a protection device and a grinding device. When the high-frequency steering engine drives the second grinding disc to rotate reversely, the grinding main disc and the ball bearings slide to the right, so that the powder passing through the grinding cylinder is pushed into the second collision grinding cylinder of the collision grinding device by the ball bearings, meanwhile, the two variable-position electric push rods at the bottom right of the protection shell drive the variable-position supporting feet to retract upward, and the two variable-position electric push rods at the bottom left of the protection shell drive the variable-position supporting feet to extend downward, so that the protection device as a whole is inclined to the right, and the inclination angle ranges from 0 to 5 degrees, thereby effectively preventing the accumulation and blockage of the powder. When the high-frequency steering engine continuously operates, vibration and heat are generated, which are directly transmitted to the grinding arc-shaped plate of the grinding device and the powder on the grinding arc-shaped plate, so that the viscosity of the powder is reduced and the flowability of the powder is improved.

Description

Technical Field

[0001] This invention relates to the field of glycyrrhizin pulverization technology, and particularly to a glycyrrhizin nanoscale pulverizer. Background Technology

[0002] Glycyrrhizin, a natural flavonoid extracted from the root of *Glycyrrhiza glabra*, is widely recognized as a highly effective skin-whitening ingredient. Its core mechanism of action lies in its potent inhibition of tyrosinase activity, blocking melanin production at its source. It also possesses excellent anti-inflammatory and antioxidant capabilities, reducing post-inflammatory hyperpigmentation and combating free radical damage. However, this ingredient faces two major challenges in application: firstly, its extremely low water solubility makes it difficult to maintain stability in formulations; secondly, its large molecular structure and lipophilicity hinder its effective penetration into the stratum corneum, resulting in low bioavailability. Therefore, to overcome these bottlenecks, modern formulation technology often employs nano-scale processing. Nanotechnology not only significantly improves the skin absorption rate and efficacy of glycyrrhizin but also enhances its chemical stability during product storage, ensuring the full realization of its whitening and skincare effects and the consistent and reliable quality of the product. This is a key strategy for enhancing the modern application value of traditional plant active ingredients.

[0003] Existing glycyrrhizin pulverizers generally use a single pulverizing method to pulverize glycyrrhizin. Although this method is easier to maintain, its pulverizing efficiency and effect are difficult to guarantee, and it cannot further increase the fineness of the pulverization. In existing technologies, to ensure the pulverizing effect, the corresponding pulverizing gaps are left with small gaps. When grinding in the horizontal direction, it is difficult to guarantee the powder's advance speed, which easily causes powder blockage. When grinding in the vertical direction, the powder falls too fast, resulting in an inability to guarantee the pulverizing effect. At the same time, existing glycyrrhizin pulverizers cannot utilize the residual heat of the motor to a certain extent during operation. Therefore, there is a need for a glycyrrhizin nano-scale pulverizer that can increase the pulverizing steps and pulverizing effect, prevent powder blockage, and effectively utilize the motor's heat energy to overcome the shortcomings of existing glycyrrhizin nano-scale pulverizers.

[0014] The beneficial effects of the present invention compared with the prior art are: (1) The high-pressure jet pump first sucks the raw material into the high-pressure jet pump through the collection hole, and then the high-pressure jet pump sprays the raw material out at high speed from the jet horn. The sprayed raw material will be divided into three parts by the diversion hole of the diversion ring and sprayed into the three areas of the grinding component respectively. During the process of the raw material being sprayed, the material will experience severe cavitation effect, shear force and turbulent impact, so that the glycyrrhizin particles are rapidly crushed to a size close to the nanometer level. Then the glycyrrhizin particles will also follow the jet into the grinding cylinder of the grinding component. (2) When the glycyrrhizin particles are sprayed into the grinding cylinder, the high-frequency rudder in the protection device will first drive the second grinding disc of the grinding component to rotate in the forward direction. The second grinding disc drives the ball to slide to the left through the screw. The ball drives the grinding cylinder and grinding sleeve to slide to the left through the grinding main disc. Since the guide slider is slidably installed inside the guide spiral groove, the grinding sleeve will also rotate while sliding to the left. The grinding sleeve drives the grinding cylinder to rotate through friction. The grinding cylinder drives the first grinding shaft to rotate through friction. At this time, the powder that enters the grinding cylinder will be further ground by the grinding cylinder, the first grinding shaft and the second grinding shaft. (3) When the high-frequency servo motor drives the second grinding disc to rotate in the opposite direction, the grinding disc and the ball will slide to the right, so that the powder passing through the grinding cylinder is pushed into the second grinding cylinder of the impact grinding device by the ball. At the same time, the two displacement electric push rods on the right side of the bottom of the protective housing will drive the displacement support foot to retract upward, and the two displacement electric push rods on the left side of the bottom of the protective housing will drive the displacement support foot to extend downward, so that the protective device tilts to the right as a whole. The tilt angle ranges from 0° to 5°, thereby effectively preventing the accumulation and blockage of powder. (4) When the high-frequency servo motor is running continuously, it will generate a certain amount of vibration and heat. The vibration and heat will be directly transferred to the grinding arc plate of the grinding device and the powder on the grinding arc plate, thereby reducing the viscosity of the powder and improving its fluidity. At the same time, the heat of the high-frequency servo motor will also be transferred to the protective housing through the heat conduction pipe of the protective bracket, so that the temperature inside the protective housing remains consistent. At the same time, the excess heat will also be dissipated through the contact between the protective housing and the air. Attached Figure Description

[0037] Working principle of the invention: Figure 1 and Figure 2The invention provides the usage methods and corresponding scenarios. The attitude control during the use of the glycyrrhizin nano-scale pulverizer is determined by the spraying device 1, the impact and grinding device 2, and the grinding device 4. The attitude of the spraying device 1 is determined by the impact and grinding device 2, and the attitude of the grinding device 4 is determined by the impact and grinding device 2. Therefore, the impact and grinding device 2 is the core of the use of the glycyrrhizin nano-scale pulverizer.

[0038] Taking a preferred embodiment as an example, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, firstly, a suspension containing coarse glycyrrhizin particles is poured into an inclined collection tray 103. The suspension will collect along the slope of the collection tray 103 to the periphery of the collection hole 102. Then, the high-pressure jet pump 101 first draws the raw material into the high-pressure jet pump 101 through the collection hole 102. Subsequently, the high-pressure jet pump 101 ejects the raw material at high speed from the jet nozzle 104 of the sealing cover 105. The ejected raw material is first divided into three parts by the diversion hole 202 of the diversion ring 201, and sprayed into three areas of the grinding component 206 respectively. During the ejection process, the raw material will experience severe cavitation effect, shear force and turbulent impact. This process rapidly pulverizes glycyrrhizin particles to near-nanoscale sizes, after which the particles follow the jet into the grinding cylinder 212 of the grinding assembly 206. During the process of the glycyrrhizin particles being sprayed into the grinding cylinder 212, the high-frequency servo motor 304 within the protection device 3 first drives the second grinding disc 227 of the grinding assembly 207 to rotate forward. The second grinding disc 227, through the first grinding disc 226 and the screw 222, drives the ball bearing 221 to slide to the left. The ball bearing 221, through the main grinding disc 217, drives the grinding cylinder 212 and the grinding sleeve 215 to slide to the left. Since the guide slider 218 is slidably installed inside the guide spiral groove 204... As the grinding sleeve 215 slides to the left, it also rotates. At this time, the grinding sleeve 215 drives the grinding cylinder 212 to rotate via friction. The grinding cylinder 212, in turn, drives the first grinding shaft 213 to rotate via friction, further grinding the powder inside the grinding cylinder 212. This results in the powder being further ground by the grinding cylinder 212, the first grinding shaft 213, and the second grinding shaft 214. When the high-frequency servo motor 304 drives the second grinding disc 227 to rotate in the opposite direction, the high-frequency servo motor 304 drives the second grinding disc 227 and the first grinding disc 226 to rotate in the opposite direction. The first grinding disc 226, through the screw 222, drives the grinding main disc 217 and the ball bearings 221 to rotate towards... Sliding to the right, the powder passing through the grinding cylinder 212 is pushed by the ball bearing 221 into the second grinding cylinder 205 of the impact grinding device 2. Then, the second grinding disc 227 and the first grinding disc 226 rotate in the forward direction. The first grinding disc 226 drives the grinding protrusion 223 to grind the powder again through the screw 222. During the grinding process, the powder slides slowly to the right in the grinding trough 224 through the tilt angle adjusted by the protection device 3. When the powder reaches the rightmost side of the grinding trough 224, the powder will slide down along the discharge trough 225. During the sliding process, the grinding gap between the second grinding disc 227 and the second grinding cylinder 205 will grind the powder.When a large amount of coarse glycyrrhizin particles accumulate on the left side of the grinding assembly 206, the grinding assembly 206 slides to the left. The conical structure of the conical platform 216 pushes the large amount of coarse glycyrrhizin particles towards the opening of the grinding cylinder 212. During the leftward sliding of the grinding main disc 217, the limiting cylinder 219 slides to the left along with the grinding main disc 217, while the limiting cover 220 slides to the right relative to the limiting cylinder 219, causing the right end of the limiting cylinder 219 to separate from the left end of the limiting cover 220. At this time, the glycyrrhizin powder will enter the right side space of the grinding assembly 206 from the right end of the limiting cylinder 219. After the discharge plug 210 on the discharge cylinder 209 is pulled out, the glycyrrhizin powder that has undergone the first grinding will be discharged directly from the discharge cylinder 209. The fitting concave surface 229 on the plug body 228 is used to fit the inner cylindrical surface of the first grinding cylinder 203.

[0039] like Figure 9 and Figure 10 As shown, during the operation of the crushing device 2, the two displacement electric actuators 307 on the right side of the bottom of the protective housing 301 will drive the displacement support feet 308 to retract upwards, and the two displacement electric actuators 307 on the left side of the bottom of the protective housing 301 will drive the displacement support feet 308 to extend downwards, causing the protective device 3 to tilt to the right as a whole. The tilt angle ranges from 0° to 5°, thereby effectively preventing the accumulation and clogging of powder. When the high-frequency servo motor 304 operates continuously, it will generate a certain amount of vibration and heat. The vibration and heat will be directly transferred to the grinding arc plate 401 of the grinding device 4 and the powder on the grinding arc plate 401, thereby reducing the viscosity of the powder and improving its fluidity. At the same time, the heat from the high-frequency servo motor 304 will also be transferred through the protective bracket 303. The heat is transferred to the protective shell 301 through the heat pipe, so that the temperature inside the protective shell 301 remains constant. At the same time, excess heat is dissipated through the contact between the protective shell 301 and the air. As the powder moves in the grinding arc plate 401, the powder falls from the grinding hole 403 onto the arc-shaped concave seat 305. Then, the second grinding disc 227 drives the grinding arc plate 401 to rotate back and forth through the connecting frame 402. The grinding arc plate 401 drives the fan-shaped grinding disc 406 to swing back and forth through the grinding bracket 404. At the same time, the piezoelectric ceramic 405 generates ultrasonic waves to the powder, thereby achieving thorough pulverization of the powder. Then, the discharge pump 306 discharges the nano-level glycyrrhizin powder. The protective baffle 302 is fixedly installed inside the protective shell 301.
