Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to a particle size detection device and a detection method for traditional Chinese medicine granules. Background Art

[0002] Intelligent manufacturing in the field of traditional Chinese medicine has become one of the key paths to promote the development of traditional Chinese medicine. Through intelligent manufacturing, personalized customization, flexible scheduling, network transmission and full system interconnection of traditional Chinese medicine products can be achieved, thereby greatly improving production efficiency, reducing energy consumption, improving product quality, and meeting the diverse needs of the market. In the production process of traditional Chinese medicine granules, the quality of the formed granules is directly related to the efficacy and effectiveness of the final product. Particle size is a key indicator for the quality evaluation of traditional Chinese medicine granules. It not only affects the physical form and stability of the product, but also profoundly affects the dissolution rate, bioavailability and final efficacy of the drug. Too small a particle size may cause the fluidity of traditional Chinese medicine granules to deteriorate, making it difficult to handle during production, packaging and transportation, and may also increase energy consumption and costs in the production process because more energy is required to crush these particles for re-granulation. On the contrary, too large a particle size may cause the traditional Chinese medicine granules to slow down when dissolving, affecting the release and absorption efficiency of the drug, thereby weakening the efficacy of the drug. Therefore, accurate detection of the particle size of traditional Chinese medicine granules is of vital importance to ensure the overall quality of the granules.

[0003] At present, the conventional method for detecting particle size is usually manual screening. This method takes a long time to detect and has low analysis efficiency. It has certain limitations and is difficult to meet the development needs of intelligent manufacturing. In recent years, with the development of science and technology, visual inspection technology has gradually been applied to the quality control of traditional Chinese medicine preparations. Among them, image recognition technology has received widespread attention as a simple, fast and non-destructive detection method. The premise of visual inspection is to obtain clear particle images, but for traditional Chinese medicine granules in the production process, they are often in a mixed state of powder particles, and the camera cannot directly obtain the image information of the particles. It can be seen that the existing particle size detection method of traditional Chinese medicine granules is not accurate and stable and affects production efficiency. Summary of the invention

DETAILED DESCRIPTION

[0041] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] like Figure 1-3 As shown, a particle size detection device for Chinese medicine granules includes an assembly base 1, a rotary feeding mechanism 2 is provided on the assembly base 1, the rotary feeding mechanism 2 includes a particle dispersion mechanism 3 on one side, an oscillating feeding assembly 4 is connected to the output end of the rotary feeding mechanism 2 and the entrance end of the particle dispersion mechanism 3, and a particle size detection mechanism 5 is provided on the upper side of the particle dispersion mechanism 3, a digital display mixing controller 7 is provided on the assembly base 1, and the digital display mixing controller 7 is respectively connected to and controls the rotary feeding mechanism 2, the particle dispersion mechanism 3, the oscillating feeding assembly 4, and the particle size detection mechanism 5, and the digital display mixing controller 7 and the control platform 6 perform data transmission and control command transmission.

[0043] Among them, the rotary feeding mechanism 2 includes a rotary feeding hopper 21, a first piezoelectric ceramic vibrator 22 is provided at the bottom of the rotary feeding hopper 21, and a positioning base 23 is provided on the lower side of the first piezoelectric ceramic vibrator 22, the upper end surface of the positioning base 23 is connected with a linkage connecting piece 25 through a positioning screw 24, and the linkage connecting piece 25 is provided with a strip-shaped movable limiting groove 251 for the positioning screw 24 to pass through, and the end of the linkage connecting piece 25 away from the strip-shaped movable limiting groove 251 is connected to the bottom of the first piezoelectric ceramic vibrator 22 through a locking screw 252 and fixed, and a shock-absorbing rubber column 253 is sleeved on the circumferential outer side of the locking screw 252, and the upper end of the shock-absorbing rubber column 253 is in contact with the first piezoelectric ceramic vibrator 22 and the lower end is in contact with the linkage connecting piece 25.

[0044] It can be seen that a first inclined spring sheet is provided at the bottom of the rotating feeding hopper 21, a spiral feeding groove 26 is provided on the circumferential inner wall of the rotating feeding hopper 21, and the bottom of the rotating feeding hopper 21 is conically arranged and is connected to the first piezoelectric ceramic vibrator 22 through a vibration connecting rod 27, and a discharge port 28 is provided on the rotating feeding hopper 21 and at the end of the spiral feeding groove 26, and the first piezoelectric ceramic vibrator 22 is connected to the digital display mixing controller 7.

[0045] When feeding is required, the digital display mixing controller 7 controls the first piezoelectric ceramic vibrator 22 under the rotating feeding hopper 21, so that the rotating feeding hopper 21 performs high-frequency vibration up and down in the vertical direction, and the first inclined spring sheet connected to the rotating feeding hopper 21 causes the rotating feeding hopper 21 to perform torsional vibration in one direction, and the Chinese medicine granules in the rotating feeding hopper 21 will continue to rise forward along the spiral feeding trough 26. When it rises to the end of the rotating feeding hopper 21, it enters the discharge port 28 and transmits the particles to the swing feeding assembly 4.

[0046] During the rising process, the Chinese medicine granules in the production process are vibrated and dispersed for the first time, and the uniformity of the distribution of the Chinese medicine granules is ensured. After the Chinese medicine granules are loaded, the digital display mixing controller 7 controls the first piezoelectric ceramic vibrator 22 to stop the up and down high-frequency vibration, and the Chinese medicine granules stop rising, thereby stopping the feeding.

[0047] Obviously, the swing feed assembly 4 includes an inclined motor mounting frame 41, which is positioned by a positioning connecting column 42 arranged on the assembly base 1, and a swing motor 43 is provided on the motor mounting frame 41, and a linkage plate frame 45 is connected to the motor mounting frame 41 through a swing connecting rod 44, the output end of the swing motor 43 is connected to the linkage plate frame 45, and a swing feed trough 46 is installed on the upper end of the linkage plate frame 45, and the feed end of the swing feed trough 46 is connected to the discharge port 28 through a linear feeding frame 47.

[0048] Furthermore, the swing feed trough 46 includes a main feed trough 461, and side feed troughs 462 are respectively provided on both sides of the main feed trough 461, and the discharge ends of the side feed troughs 462 are separated from the discharge ends of the main feed trough 461, and the feed ends of the side feed troughs 462 and the feed ends of the main feed trough 461 share the same feed inlet, and one ends of the two side feed troughs 462 are cross-inserted in the main feed trough 461 and form a plurality of discharge buffer areas 463 in the main feed trough 461, and material passing through holes 464 are provided between the discharge buffer areas 463 and the side feed troughs 462 and the main feed trough 461, and the side feed troughs 462 and the bottom of the main feed trough 461 are connected to the linkage plate frame 45 through a swing linkage base 465 to form a positioning.

[0049] After the granules are loaded onto the linear feeding rack 47 by the rotary feeding mechanism 2, the linear feeding rack 47 delivers the Chinese medicine granules to the swinging feed trough 46. When swing feeding is required, the digital display mixing controller 7 regulates the swing motor 43, and the swing motor 43 drives the swing connecting rod 44 to perform a swinging motion in an elliptical trajectory. The swinging feed trough 46 located on the swing connecting rod 443 will then regularly swing in the left and right directions, and the Chinese medicine granules will be evenly distributed on the particle dispersion mechanism 3.

[0050] The digital display mixing controller 7 can control the swing amplitude and swing frequency of the swing feeding trough 46 to control the uniform distribution of the Chinese medicine granules. After the swing feeding of the Chinese medicine granules is completed, the swing motor 43 controlled by the digital display mixing controller 7 stops driving the swing connecting rod 44, and the swing feeding trough 4 stops swinging in the left and right directions, and stops feeding.

[0051] Furthermore, the particle dispersion mechanism 3 includes a particle dispersion groove 31, a second piezoelectric ceramic vibrator 32 is provided at the bottom of the particle dispersion groove 31, and the bottom of the second piezoelectric ceramic vibrator 32 is connected to a fixed base 34 through an elastic shock-absorbing seat 33, and the fixed base 34 is fixedly set on the assembly base 1, and one end of the particle dispersion groove 31 close to the swing feeding assembly 4 is closed and the other end is open, and a second inclined spring sheet is provided between the bottom of the particle dispersion groove 31 and the second piezoelectric ceramic vibrator 32.

[0052] When it is necessary to disperse the granules, the digital display mixing controller 7 controls the two piezoelectric ceramic vibrators 32 under the granule dispersion tank 31, so that the granule dispersion tank 31 performs high-frequency vibration up and down in the vertical direction, and the second inclined spring connected to the granule dispersion tank 31 makes the granule dispersion tank 31 perform torsional vibration in one direction, and the Chinese medicine granules in the granule dispersion tank 31 will be continuously dispersed forward along the granule dispersion tank 31. The granule dispersion tank 31 performs a second vibration dispersion on the Chinese medicine granules, flattens the Chinese medicine granule powder in the production process, reduces the powder stacking phenomenon, and allows the Chinese medicine granules to be clearly displayed on the surface of the granule dispersion tank 31. After the Chinese medicine granules are dispersed, the digital display mixing controller 7 controls the second piezoelectric ceramic vibrator 32 to stop the high-frequency vibration up and down, the granule dispersion tank 31 stops vibrating, and the Chinese medicine granules stop dispersing.

[0053] Specifically, the particle size detection mechanism 5 includes an industrial camera 51 , a laser scale 52 is provided at the end of the particle dispersion tank 31 , and a first light source 53 and a second light source 54 are provided on the left and right sides above the particle dispersion tank 31 through brackets.

[0054] The height of the industrial camera 51 can be adjusted up and down, and the lighting angle and lighting position of the first light source 53 and the second light source 54 are adjustable.

[0055] The particle size detection mechanism 5 is used to detect the particle size of the Chinese medicine granules and analyze the proportion of each particle size. The particle size detection mechanism 5 does not contact the granule dispersion mechanism 3, and the shock absorption treatment of the elastic shock absorption seat 33 reduces the influence of vibration on the detection result to the greatest extent.

[0056] Before detection, the pixel accuracy of the industrial camera 51 is calibrated using a laser scale 52 to ensure the accuracy of particle size detection. When granule size detection is required, the particle dispersion mechanism 3 makes the powder of the Chinese medicine granules flat and spreads the particles so that they do not stack. When the particles move to the end of the particle dispersion tank 312, the industrial camera 51 and the first light source 53 and the second light source 54 start working. The industrial camera 51 continuously captures multiple images. Based on the captured images, the particle visual detection model detects the Chinese medicine particles in the image, counts the number and proportion of particles in each interval, and generates graphical detection results.

[0057] like Figure 4 As shown, a method for detecting the particle size of a Chinese medicine granule comprises the following steps:

[0058] S1, particle vibration dispersion;

[0059] S2, particle size visual inspection;

[0060] S3, control platform 6 to store particle size data;

[0061] S4, the control platform 6 compares the particle size data and uses the digital display mixing controller 7 to adjust the vibration amplitude.

[0062] Step S1 is specifically divided into the following steps:

[0063] S1. Select samples from the production process of Chinese medicine granules;

[0064] S2, vibration dispersion of granule powder in the sample;

[0065] S3, vibration dispersion of formed particles in the sample;

[0066] In step S2, the Chinese medicine granules are fed into the rotary feeding hopper 21, and the rotary feeding hopper 21 performs a vibration dispersion on the Chinese medicine granules to remove the granule powder. The Chinese medicine granules after vibration dispersion continuously rise along the spiral feeding trough 26 in the rotary feeding hopper 21 and are fed to the discharge port 28. The Chinese medicine granules are fed to the swing feeding trough 46 along the linear feeding rack 47;

[0067] In step S3, the swinging feeding trough 46 swings left and right to evenly spread the granules in the granule dispersion trough 31. The granule dispersion trough 31 performs secondary vibration dispersion on the powder to reduce the powder stacking phenomenon. At the same time, the formed particles are also vibrated and dispersed to complete the dispersion of the granules in the production process.

[0068] The production process of Chinese medicine granules is dry granulation or wet granulation;

[0069] Samples from the production process of Chinese medicine granules are a mixture of shaped granules and powder, or contain only shaped granules without powder;

[0070] The granule dispersion method in the production process of traditional Chinese medicine granules is a dispersion method that combines multi-stage vibration dispersion with swing dispersion.

[0071] Step S2 is specifically divided into the following steps:

[0072] S21, using the industrial camera 51 to collect a picture of the dispersion state of the granules at the end of the dispersion tank;

[0073] S22, marking the formed particles;

[0074] S23, using the deep learning YOLOv5 visual detection algorithm to establish and train a particle detection model;

[0075] S24, using the equivalent circle area method to obtain particle size data and particle size distribution of the detected molded particles;

[0076] In steps S3-S4, the control platform 6 stores the obtained particle size data and distribution data, compares them with the preset standard data, and adjusts the vibration frequencies of the first piezoelectric ceramic vibrator 22, the swing motor 43 and the second piezoelectric ceramic vibrator 32 according to the comparison data.

[0077] In summary, the principle of this embodiment is that the rotating feeding mechanism 2 feeds the Chinese medicine particles and performs the first vibration dispersion; the Chinese medicine particles after vibration dispersion enter the swing feeding component 4, and the swing feeding component 4 evenly disperses the Chinese medicine particles transported by the rotating feeding mechanism 2; the Chinese medicine particles after uniform dispersion enter the particle dispersion mechanism 3, and the particle dispersion mechanism 3 performs a second vibration dispersion on the Chinese medicine particles transported by the swing feeding component 4. When the particle size detection mechanism 5 performs detection, the industrial camera 51 takes pictures of the Chinese medicine particles after the second vibration dispersion and performs particle size detection.
