Description

Technical Field

[0001] This utility model relates to the field of cosmetic science and technology, and in particular to a sample pulverizer for cosmetic microbial testing. Background Technology

[0002] A sample grinder for cosmetic microbiology testing is a laboratory device specifically designed to process cosmetic samples for microbiological testing. The main purpose of this device is to grind solid or semi-solid cosmetic samples into fine particles or powder, thereby facilitating subsequent microbiological analysis.

[0003] Although existing sample grinders for cosmetic microbial testing can efficiently grind solid or semi-solid cosmetic samples into fine particles or powder, there are still significant shortcomings in the sample collection process after grinding. The ground powder tends to accumulate locally inside the collection container, especially in the central area. This uneven distribution not only leads to large differences in sample density but may also affect the uniformity of microbial distribution, thereby reducing the representativeness and accuracy of subsequent test results. In addition, due to powder accumulation, staff often need to manually adjust the sample position or use auxiliary tools such as scrapers to re-spread and disperse the powder during sampling, which is cumbersome and inefficient. At the same time, this manual intervention increases the risk of external contamination, further affecting the reliability of experimental data. Therefore, there is still considerable room for improvement in the post-grinding processing of existing equipment, and an optimized structural design that can achieve uniform powder distribution and facilitate sampling is urgently needed.

[0004] To address the existing problems, there is a need to provide a sample pulverizer for cosmetic microbial testing that can flatten powder. Utility Model Content

[0005] To overcome the drawback of not being able to flatten powder, this invention provides a sample pulverizer for cosmetic microbial testing.

[0006] The technical implementation scheme of this utility model is as follows: A sample pulverizer for cosmetic microbial testing includes a base, a first connecting plate, a processing frame, a feeding ring, a first motor, a pulverizing rod, a first mounting frame, a guide rod, a lead screw, a second motor, a sealing plate, a second connecting plate, a damping shaft, a collection frame, a third motor, a rotating frame, a third connecting plate, and a switch plate. The first connecting plates are symmetrically connected to the left and right sides of the base, and the processing frame is connected between the first connecting plates. A feeding ring is connected to the top of the processing frame, and the first motor is mounted on the top of the processing frame. The output shaft of the first motor passes through the processing frame and is connected to the pulverizing rod. The first mounting frame is mounted on the processing frame. A guide rod is connected to the first mounting bracket, and a lead screw is rotatably connected to the first mounting bracket. A second motor is mounted on the rear side of the first mounting bracket, and the output shaft of the second motor passes through the first mounting bracket and is connected to the lead screw. A sealing plate is threaded onto the lead screw, and the sealing plate slides with the guide rod and contacts the processing frame. Second connecting plates are symmetrically connected to the base, and damping shafts are rotatably connected to the inner sides of both second connecting plates. A collection frame is connected between the two damping shafts, and a third motor is mounted at the bottom of the collection frame. The output shaft of the third motor passes through the collection frame and is connected to a rotating frame. Third connecting plates are symmetrically connected to the collection frame, and a switch plate is slidably connected between the two third connecting plates.

[0007] Preferably, the device also includes a second mounting bracket, shock-absorbing springs, a guide ring, and a vibration module. The second mounting bracket is mounted on the collection frame, and shock-absorbing springs are symmetrically connected to the second mounting bracket. A guide ring is connected between the tops of the two shock-absorbing springs, and a vibration module is installed inside the guide ring.

[0008] Preferably, it also includes a first magnet and a second magnet, with the first magnet symmetrically mounted on the left and right sides of the switch plate, and the second magnet mounted on both third connecting plates.

[0009] Preferably, it also includes a set square, with set squares symmetrically connected on the left and right sides of the second mounting bracket.

[0010] Preferably, the guide ring is conical.

[0011] Preferably, the feed ring is funnel-shaped.

[0012] The beneficial effects of this utility model are as follows: 1. The pulverized powder can be evenly distributed in the collection frame by the rotation of the rotating frame, under the cooperation of centrifugal force or scraper structure, which significantly improves the accumulation state of the powder, enhances the uniformity of sample distribution, and thus enhances the representativeness of the sampling results and the accuracy of the test data.

[0013] 2. By setting a second mounting bracket, shock-absorbing springs, guide rings, and vibration modules in the equipment, not only can the powder falling from the middle be guided and diverted to avoid concentrated accumulation in the collection area, but the auxiliary vibration of the vibration module can also make the powder more evenly distributed in the collection frame. The guide ring is preferably a conical structure, which can further improve the smoothness of powder falling. At the same time, in conjunction with the buffering effect of the shock-absorbing springs, the impact force generated during vibration is effectively absorbed, ensuring the stability and reliability of the equipment operation.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example: A sample pulverizer for microbial testing of cosmetics, such as... Figures 1-6As shown, the device includes a base 1, a first connecting plate 2, a processing frame 3, a feeding ring 4, a first motor 5, a crushing rod 6, a first mounting bracket 8, a guide rod 9, a lead screw 10, a second motor 11, a sealing plate 12, a second connecting plate 13, a damping shaft 14, a collecting frame 15, a third motor 16, a rotating frame 17, a third connecting plate 18, a switch plate 19, a second mounting bracket 20, a shock-absorbing spring 21, a guide ring 22, a vibration module 23, a first magnet 24, a second magnet 25, and a triangular plate 26. The first connecting plates 2 are symmetrically connected to the left and right sides of the base 1. The processing frame 3 is connected between the first connecting plates 2 to hold the cosmetic sample to be crushed. The top of the processing frame 3 is connected to... Feed ring 4, funnel-shaped, serves as the sample feeding channel. The funnel design helps guide the sample smoothly into processing frame 3. A first motor 5 is mounted on the top of processing frame 3. The output shaft of the first motor 5 passes through processing frame 3 and connects to a crushing rod 6 for crushing the cosmetic sample. A first mounting frame 8 is mounted on processing frame 3, with a guide rod 9 connected to it. A lead screw 10 is rotatably connected to the first mounting frame 8. A second motor 11 is mounted on the rear side of the first mounting frame 8. The output shaft of the second motor 11 passes through the first mounting frame 8 and connects to the lead screw 10. A sealing plate 12 is threaded onto the lead screw 10, and the sealing plate 12 slides against the guide rod 9. The base 1 has two symmetrically connected second connecting plates 13 that contact and cooperate with the processing frame 3. Each of the two second connecting plates 13 has a damping shaft 14 rotatably connected to its inner side. A collection frame 15 is connected between the two damping shafts 14 to receive the pulverized sample powder and to serve as a container for subsequent sampling and leveling operations. A third motor 16 is installed at the bottom of the collection frame 15. The output shaft of the third motor 16 passes through the collection frame 15 and is connected to a rotating frame 17 to evenly level the powder inside the collection frame 17, preventing accumulation and improving sample representativeness. A third connecting plate 18 is symmetrically connected to the collection frame 15, and a switch plate 19 is slidably connected between the two third connecting plates 18. A second mounting bracket 20 is installed on frame 15. Shock-absorbing springs 21 are symmetrically connected to the second mounting bracket 20. A guide ring 22 is connected between the tops of the two shock-absorbing springs 21. The guide ring 22 is conical and guides the powder falling in the middle, allowing it to slide down the inclined surface to avoid accumulation and improve the uniformity of powder distribution. A vibration module 23 is installed inside the guide ring 22 to generate high-frequency vibration, shaking off residual powder adhering to the surface of the guide ring 22 and improving sample recovery rate and cleanliness. A first magnet 24 is symmetrically installed on the switch plate 19. A second magnet 25 is installed on each of the two third connecting plates 18. A triangular plate 26 is symmetrically connected to the second mounting bracket 20.

[0023] When cosmetic samples need to be pulverized, the operator first places the sample into the top feed ring 4. The sample falls naturally through the funnel-shaped structure of the feed ring 4 into the processing frame 3 below. After the sample is placed, the operator starts the first motor 5, whose output shaft drives the pulverizing rod 6 to rotate at high speed, thoroughly pulverizing the cosmetic sample in the processing frame 3. After pulverization, the first motor 5 is turned off. Then, the operator starts the second motor 11, whose output shaft drives the lead screw 10 to rotate. The lead screw 10 is threadedly connected to the sealing plate 12, causing the sealing plate 12 to slide backward along the guide rod 9, thereby... Open the outlet at the bottom of processing frame 3. The pulverized sample falls from the bottom of processing frame 3 under gravity. Samples in the outer ring fall directly into the collection frame 15 below, while samples in the central area first fall onto the surface of the guide ring 22 below, then slide down its slope into the collection frame 15, ensuring a more uniform sample distribution and reducing accumulation. Once the sealing plate 12 has moved to the appropriate position, turn off the second motor 11. During this process, the operator can simultaneously start the vibration module 23. The vibration module 23 drives the guide ring 22 to vibrate at high frequency, effectively shaking off residual powder adhering to its surface and improving sample recovery rate. Meanwhile, the shock-absorbing spring 21 is connected between the guide ring 22 and the second mounting bracket 20 to absorb the impact force generated during vibration and ensure the stability of the equipment operation. At the same time, the third motor 16 can be started, and its output shaft drives the rotating frame 17 to rotate, so as to evenly spread the sample powder inside the collection frame 15, forming a thin layer of uniform thickness inside the collection frame 15, which is convenient for subsequent sampling operations. After the spreading is completed, the vibration module 23 and the third motor 16 are turned off. At this time, the staff can perform fixed-point sampling or mixed sampling on the spread sample surface to ensure that the sample is representative. After sampling is completed, the staff slides upwards to open The switch plate 19 is slid up along the two third connecting plates 18. When the switch plate 19 is raised to the appropriate position, the first magnet 24 installed on it and the second magnet 25 on the third connecting plate 18 are magnetically attracted to each other, fixing the switch plate 19 in the open state. Then, the staff pushes the collection frame 15 upward, which rotates through the damping shafts 14 on both sides. The collection frame 15 can slowly rotate and tilt around the damping shafts 14, so that the sample powder inside can smoothly slide into the external collection container under the action of gravity, which is convenient for centralized recycling. After the sample collection is completed, the staff resets the collection frame 15 to return it to the horizontal state, ready for the next operation.
