Description

Technical Field

[0001] The invention relates to the technical field of sampling, in particular to a sampling device for cosmetics testing. Background Art

[0002] Cosmetics refer to chemical industrial products or fine chemical products that are spread on any part of the human body surface, such as skin, hair, nails, lips and teeth, by smearing, spraying or other similar methods, for the purpose of cleaning, maintenance, beautification, modification and change of appearance, or correction of body odor and maintenance of good condition.

[0003] There are many types of cosmetics, and most of them come into direct contact with human skin when used. Therefore, cosmetics need to be tested before leaving the factory. The projects mainly include microbial and material component testing. Products with different functions also have different material forms. Due to the limitations of density and molecular motion differences, liquids mixed with various substances can make use of the recognition of testing instruments to reduce the difficulty of testing and improve the accuracy of the data obtained.

[0004] However, the existing sampling equipment for cosmetics testing has the following shortcomings:

[0005] In order to obtain the accurate content of each substance measured in solid cosmetic products, a sample liquid with an appropriate proportion needs to be prepared before the product is tested. However, due to its own structural limitations, traditional equipment can only complete relatively simple solid material sampling. Subsequently, the sample material needs to be processed manually or by auxiliary machines to complete the sample liquid preparation. During the process, the initial amount of the sample material will change slightly after the transfer, resulting in errors in the water supply ratio, affecting the data results of some substances.

[0006] Therefore, we propose a sampling device for cosmetics testing to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide a sampling device for cosmetics testing, which controls the size of the discharge square tube channel through a sample liquid preparation mechanism connected to an assembly base, continuously completes the release of the material to be tested, and when the material is transferred to a lower container, the material increment data is counted in real time by a metering scale, and then the system controls the relevant components according to the actual numerical value, and gradually reduces the material release amount by adjusting the material lowering rate, and controls the final locked weight value within a specified range. Subsequently, the metering scale is reset to zero again to complete the metering of the injected clean water, and the mechanical transmission component further accelerates the mixing of the material and the clean water, and finally a 1:1 mixed liquid for testing is obtained, so as to solve the problems raised by the above-mentioned background technology.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention sets a sample liquid preparation mechanism to control the size of the discharge square tube channel and continuously complete the release of the material to be tested. After the material is transferred to the lower container, the metering scale counts the material increment data in real time, and then the system controls the relevant components according to the actual numerical value, and gradually reduces the material release amount by adjusting the material lowering rate, and controls the final locked weight value within a specified range. The subsequent metering scale is reset to zero again to complete the metering of the injected clean water, and the mechanical transmission component further accelerates the mixing of the material and the clean water to finally obtain a 1:1 mixed liquid that can be tested. The mechanism uses the mechanical transmission principle to complete the sampling and weighing of solid materials and clean water one by one. With the assistance of relevant components, it reasonably obtains an appropriate amount of solid materials and clean water, and uses physical stirring to accelerate the mixing of materials and water, so as to quickly obtain a stable and measurable mixed liquid, thereby avoiding the influence of the clean water ratio error on some substances in the material and the obtained sample liquid detection result.

[0022] 2. The present invention provides a sample liquid preparation mechanism. Before the material is sampled and weighed, it can be poured into the interior of the material storage box. By utilizing physical vibration, the material retained on the perforated screen will be continuously screened, and material particles of equal size will be quickly screened out, thereby preventing large pieces of material from entering the subsequent mixed liquid, increasing the difficulty of dissolving the material in water, and shortening the sample liquid preparation time.

[0023] 3. The present invention sets a residual liquid adsorption mechanism. Since water has a certain tension and the friction provided by the inner wall of the transition tube, a large number of water droplets are often hung on the inner wall of the transition tube after cleaning. The mechanism adopts a physical brushing method. When the adapter head enters the interior of the transition tube longitudinally, the absorbent felt can fill the inner wall of the transition tube. The absorbent characteristic of the absorbent felt material is utilized to fully clean the water droplets hanging on the wall, thereby avoiding interference with the ongoing sampling due to the slow drying of the residual liquid due to the closure of the container.

[0040] according to Figure 1 and Figure 7 As shown, the residual liquid adsorption mechanism 3 includes a third locking frame 301, the bottom of the third locking frame 301 is fixedly installed on the top of the assembly base 1, the interior of the third locking frame 301 is fixedly installed with a steering motor 302, the top of the assembly base 1 is fixedly installed with an L-shaped frame 303, the outer wall of the L-shaped frame 303 is fixedly installed with a second external ring 304, the inner wall of the second external ring 304 is fixedly installed with a coupling 305, and the shaft end of the steering motor 302 is connected to the power output end of the coupling 305.

[0041] according to Figure 7 and Figure 8 As shown, the power output end of the coupling 305 is fixedly connected to a transmission rod 306, the outer wall fixed sleeve of the transmission rod 306 is provided with a solid rod 307, the outer wall fixed sleeve of the solid rod 307 is provided with a group of second positioning sleeves 308, and a fourth load-bearing support plate 309 is fixedly installed between the outer walls of the group of second positioning sleeves 308.

[0042] according to Figure 7 and Figure 8 As shown, two extended bases 310 are fixedly installed on the outer wall of the fourth load-bearing support plate 309, a hollow ring box 311 is fixedly installed on the outer wall of one extended base 310, a group of water inlet grooves 312 are opened on the inner wall of the hollow ring box 311, a top bracket 313 is fixedly installed on the top of the hollow ring box 311, a second electric push rod 314 is fixedly installed on the top of the top bracket 313, an adapter head 322 is fixedly sleeved on the axial end of the second electric push rod 314, and the outer wall of the adapter head 322 is wrapped with absorbent felt 323. Through the preset upper component, when the adapter head 322 penetrates into the interior of the transition tube 225, the absorbent felt 323 wrapped on its surface is in an extruded state. The water absorption property of the absorbent felt 323 material can be used to clean the liquid retained in the transition tube 225, so that the equipment can quickly prepare subsequent sample liquids.

[0043] according to Figure 7 and Figure 8 As shown, a return box 315 is fixedly installed on the outer wall of an extended base 310, and a discharge joint 316 is fixedly connected to the outer wall of the return box 315. A second electric valve 317 is arranged inside the discharge joint 316. A return joint 318 and a second drainage joint 320 are fixedly connected to the outer wall of the hollow ring box 311 and the return box 315, respectively. The drainage end of the return joint 318 is fixedly connected to a second booster pump 319 through a flange, and the output end of the second booster pump 319 is fixedly connected to a release pipe Channel 321, the drainage end of the release pipe 321 is connected to the interior of the second drainage joint 320. By presetting the above components, after the adapter head 322 is reset, it can be temporarily placed in the interior of the hollow ring box 311. Under the pressure of external force, the liquid absorbed in the absorbent felt 323 diffuses to the periphery of the hollow ring box 311 and flows into the interior of the hollow ring box 311. After the second booster pump 319 is turned on, the liquid can be transferred to the reflux box 315 to ensure that the absorbent felt 323 can always have a strong water absorption effect.

[0044] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bottom of the support plate 201 is fixedly mounted on the top of the assembly base 1 , and a group of adjustable feet 5 are fixedly mounted on the bottom of the assembly base 1 .

[0045] The effect achieved by the entire mechanism is: first move the equipment to the designated working area, and make each adjustable foot 5 stably placed on the work platform, and then connect the external line to the power supply of the equipment to provide energy for multiple electrical components therein, and then connect the water guide outer pipe and the liquid discharge outer pipe to the water inlet joint 249 and the discharge joint 316 respectively.

[0046] During the solid material screening stage, the pre-tested material is poured into the material storage box 204 and spread flat on the top of the perforated screen 206. The first drive motor 208 is turned on to put each vibration base 207 into a vibrating state, causing the perforated screen 206 to shake continuously, and the material on it begins to be screened. The lower volume particles fall to the bottom of the material storage box 204 under the action of gravity. The purpose is to make the material particles transferred to the transition tube 225 more uniform, which can reduce the difficulty of dissolving the material in water and shorten the sample liquid preparation time.

[0047] During the weighing stage, the first electric valve 213 is opened, the size of the internal channel of the discharge square tube 212 is reasonably controlled, the material particles begin to be released, and continue to fall into the interior of the transition tube 225 under the action of gravity, gradually accumulate to the top of the cover 226, and fully contact the surface of the metering scale 227. When the surface of the metering scale 227 is covered with an object, as the material particles increase, the obtained value also shows an increasing trend. The real-time data is imported into the receiving module 233 by the information line 235 and quickly fed back to the equipment system. When the amount of material particles obtained is about to reach the specified range, the system controls the first electric valve 213 to adjust the size of the channel of the discharge square tube 212 to change the material particles. The material discharge rate is changed until the material sampling volume is controlled within the specified range, and the release of the material particles is stopped. Clean water is further introduced from the water inlet joint 249 to keep the connection box 229 filled. The first booster pump 232 is turned on to start extracting clean water from the connection box 229. The clean water is transported by the first water pipe 241 and the second water pipe 242 and finally poured into the interior of the transition tube 225 from the first drainage joint 250. Prior to this, when the weight of the material particles is determined, the system controls the metering scale 227 to reset it to zero again, and then the clean water contacts the metering scale 227 to produce data changes again. The metering of the clean water is completed by the above method.

[0048] In the sample liquid preparation stage, the second drive motor 240 is started, and the U-shaped joint 236 and the cross bar 237 are used to make the associated frame 239 and its connected parts rotate synchronously, so that the cover 226 is slowly expanded. At this time, the materials and clean water in the transition cylinder 225 continue to fall to the lower level under the action of gravity, and finally gather in the mixing cylinder 218. Then the cover 226 is reset, and the first electric push rod 247 is opened to make its shaft end retract into the cavity. The slideway 202 and the T-shaped slider are used to make the horizontal plate 214 and its connected parts move slowly downward until the mixing cylinder 218 and the electromagnetic plate 218 are connected. 53 is the smallest, the servo motor 244 is turned on, and its power directly acts on the gear reducer 243 to convert the high-speed power into high-torque and low-speed. At the same time, the electromagnetic plate 253 is energized, and its surface generates magnetic force, which can continuously attract the permanent magnet strip 223 to lock the stirring rod 222 and the electromagnetic plate 253. When the electromagnetic plate 253 rotates at a low speed, the stirring rod 222 can rotate synchronously with the external force by utilizing the movable connection between the limit seat 219 and the internal plug 220, so as to achieve the purpose of stirring the material particles and the clean water. When the mixing time is reached, the sample liquid prepared in the mixing barrel 218 can be taken out.

[0049] During the cleaning stage, the cover 226 is first expanded to the maximum range, the steering motor 302 is turned on, and acts on the transmission rod 306 and the solid rod 307 to drive the fourth load-bearing support plate 309 and its connected components to complete the steering, until the hollow ring box 311 and the reflux box 315 are respectively placed on the top and bottom of the transition tube 225, the first booster pump 232 is turned on, the power is adjusted to the maximum range, and a high-speed water flow is ejected from the first drainage joint 250 to rewash the inner wall of the transition tube 225 and clean the residue retained on the inner wall. The falling cleaning liquid is collected by the reflux box 315, the second electric valve 317 is turned on, and the internal channel of the discharge joint 316 is opened to complete the discharge of the cleaning liquid. When the rewashing of the inner wall of the transition tube 225 is completed, the first booster pump 232 is turned off. , turn on the second electric push rod 314, so that its inner axis extends outward, driving the adapter head 322 to slowly descend and vertically insert into the interior of the transition tube 225. During the process, the water-absorbing felt 323 can be pressed onto the inner wall of the transition tube 225 to continuously absorb the residual water stains. After the steps are completed, the adapter head 322 begins to reset and eventually retracts to the interior of the hollow ring box 311. At this time, the water-absorbing felt 323 is squeezed by the inner wall of the hollow ring box 311, and the retained liquid will be released and diffused to the periphery, and converge from each water inlet groove 312 to the interior of the hollow ring box 311. The second booster pump 319 is simultaneously turned on to extract the cleaning liquid in the hollow ring box 311, and after being transported through the release pipe 321, it converges into the reflux box 315 and is then discharged from the discharge joint 316.
