[0002] The compound algae extract added to cosmetics and skin care products is mainly used as a moisturizer and skin conditioner. The main ingredients of compound algae extract are algin, vitamins and amino acids. It is a natural moisturizer and emollient that can promote cell regeneration, strengthen skin metabolism, have a unique exfoliating effect, can renew the skin and prevent wrinkles, and also has a good anti-inflammatory effect.

[0003] Compound algae extract is extracted from different types of seaweed. After a batch of compound algae extract is extracted in the workshop, the process requires the concentration of the compound algae extract to be tested. The specific testing method is: S1. Workers pour the extracted compound algae extract into Figure 1 The temporary storage tank 1 is shown, and the composite algae extract in the temporary storage tank 1 is allowed to stand for a period of time; S2, the worker uses a syringe to extract the compound algae extract located in the upper area of ​​the temporary storage tank 1, and then discharges the compound algae extract in the syringe into the container, thereby sampling the compound algae extract in the upper area; then the worker inserts the detection head of the concentration detector into the container, and after waiting for a period of time, the concentration of the compound algae extract in the upper area can be detected; S3, the worker repeats the operation of step S2 twice, thereby detecting the concentration of the composite algae extract in the middle layer area and the concentration of the composite algae extract in the lower layer area respectively; S4. The worker calculates the average value of the concentration of the compound algae extract in the upper region, the concentration of the compound algae extract in the middle region, and the concentration of the compound algae extract in the lower region. The average value is the concentration of the compound algae extract in the temporary storage tank 1.

[0004] However, although the operation method in the workshop can detect the concentration of the compound algae extract in the temporary storage tank 1, it still has the following technical defects: I. In steps S2-S3, workers are required to use syringes to sample the composite algae extract in the upper region, the composite algae extract in the middle region, and the composite algae extract in the lower region in three steps; and the entire sampling operation is completed manually, which undoubtedly increases the workload of the workers. In addition, it also increases the sampling time of the composite algae extract, thereby reducing the detection efficiency of the concentration of the composite algae extract.

[0005] II. In steps S2-S3, workers are required to use a concentration detector to perform concentration detection on the composite algae extract in the upper area, the composite algae extract in the middle area, and the composite algae extract in the lower area in three processes; and the entire detection operation is completed manually, which undoubtedly further increases the workload of the workers.

Workers can control the extension or retraction of the piston rods of the feed cylinder 6, the left cylinder 14, and the right cylinder 16 through the controller, and the concentration detector 9 can also transmit the detected concentration signal to the display screen of the controller for workers to view.

[0026] A method for efficiently detecting the concentration of a composite algae extract comprises the following steps: S1, workers pour the newly extracted composite algae extract to be tested into the temporary storage tank 1; S2, sampling the compound algae extract in the upper area, the compound algae extract in the middle area, and the compound algae extract in the lower area of ​​the temporary storage tank 1, and the specific operation steps are as follows: S21, control the servo motor of the screw nut pair 12 of the sampling assembly 4 to rotate forward, the servo motor drives the screw 28 to rotate forward, the nut 29 moves downward along the screw 28, the nut 29 drives the platform 13 to move downward, the platform 13 drives the left cylinder 14, the middle plate 15 and the right cylinder 16 to move downward synchronously, and then drives the left plate 22, the plugging head 23, the sampling tube 18 and the right plate 17 to move synchronously toward the direction of the composite algae extract in the temporary storage tank 1; when the platform 13 drops to the set distance, the controller controls the servo motor to turn off, at this time, the three sampling tubes 18 are respectively in the upper area, middle area and lower area of ​​the temporary storage tank 1, as shown in FIG. Fig.11 As shown; S22, control the piston rod of the left cylinder 14 to retract to the left, the piston rod drives the left side plate 22 to move to the left, and the left side plate 22 drives the three plugging heads 23 to move to the left synchronously, such as Fig.12 As shown, the plugging head 23 no longer blocks the left port of the connecting pipe 19; S23, control the piston rod of the right cylinder 16 to retract to the right, the piston rod drives the right side plate 17 to move to the right, the right side plate 17 drives the three connecting rods 21 to move to the right synchronously, the three connecting rods 21 respectively drive the slip rings 20 connected thereto to move to the right synchronously, when the slip ring 20 moves to the right in the sampling tube 18, as shown in FIG. Fig.13As shown, the composite algae extract passes through the left port of the connecting tube 19, the connecting tube 19, the right port of the connecting tube 19 in sequence, and finally enters the sampling tube 18. The flow direction of the composite algae extract is as shown in FIG. Fig.13 As shown by the middle arrow; when the piston rod of the right cylinder 16 is fully retracted, the three sampling tubes 18 respectively extract the compound algae extract from the upper region, the compound algae extract from the middle region, and the compound algae extract from the lower region; S24, control the piston rod of the left cylinder 14 to extend to the right, the piston rod drives the left side plate 22 to move to the right, the left side plate 22 drives the three plugging heads 23 to move to the right synchronously, and the three plugging heads 23 respectively block the left ports of the three connecting pipes 19 again, such as Fig.14 As shown, the sampling of the compound algae extract in the upper region, the compound algae extract in the middle region, and the compound algae extract in the lower region of the temporary storage tank 1 is finally achieved; Among them, it can be known from step S2 that the detection device can extract and seal the composite algae extract in the upper area, the middle area, and the lower area of ​​the temporary storage tank 1 in the three sampling tubes 18 respectively, only through the linkage cooperation of the screw nut pair 12, the left cylinder 14 and the right cylinder 16 of the sampling component 4. In other words, the sampling of the composite algae extract in the upper area, the composite algae extract in the middle area, and the composite algae extract in the lower area is achieved at the same time.

[0027] It can be seen that compared with the sampling method in the workshop, the detection device does not require workers to use syringes to sample the composite algae extract in the upper area, the composite algae extract in the middle area, and the composite algae extract in the lower area in three steps respectively. Instead, the sampling is automatic and simultaneous, which saves the process. It not only greatly reduces the work intensity of the workers, but also greatly shortens the sampling time of the composite algae extract, thereby greatly improving the detection efficiency of the concentration of the composite algae extract.

[0028] S3. After sampling, the servo motor of the screw nut pair 12 of the sampling assembly 4 is controlled to reverse, the servo motor drives the screw 28 to reverse, the nut 29 moves upward along the screw 28, the nut 29 drives the platform 13 to move upward, the platform 13 drives the left cylinder 14, the middle plate 15 and the right cylinder 16 to move upward synchronously, and then drives the left plate 22, the plugging head 23, the sampling tube 18 and the right plate 17 to move synchronously away from the temporary storage tank 1; when the platform 13 rises to the initial position, the controller controls the servo motor to turn off, at this time, the three plugging heads 23 are respectively opposite to the three docking tubes 8 on the left and right, such as Fig.15 As shown; S4, detecting the concentration of the composite algae extract in the three sampling tubes 18, the specific operation steps are as follows: S41, control the piston rod of the feed cylinder of the detection component 3 to extend to the right, the piston rod drives the mounting plate 7 to move to the right, and the mounting plate 7 drives the three docking tubes 8 to move to the right synchronously. When the piston rod of the feed cylinder 6 extends a certain distance, the docking tube 8 is just sleeved on the outside of the plugging head 23, as shown in FIG. Figure 16-17 As shown, at the same time, the rod 11 in the docking tube 8 just enters the liquid hole 24 in the plugging head 23; as the piston rod of the feed cylinder 6 continues to extend to the right, the rod 11 pushes the end cover 25 to the right, as shown in FIG. Fig.18 As shown, the end cover 25 no longer blocks the liquid hole 24. At this time, the docking tube 8 is just connected to the connecting tube 19. S42, control the piston rod of the right cylinder 16 to extend to the left, the piston rod drives the right side plate 17 to move to the left, the right side plate 17 drives the three connecting rods 21 to move to the left synchronously, the three connecting rods 21 respectively drive the slip rings 20 connected thereto to move to the left synchronously, when the slip ring 20 moves to the left in the sampling tube 18, the slip ring 20 squeezes the composite algae extract in the sampling tube 18 to the left, as shown in FIG. Fig.19 As shown, under the extrusion force, the composite algae extract in the sampling tube 18 passes through the right port of the connecting tube 19, the connecting tube 19, the left port of the connecting tube 19 in sequence, and finally enters the docking tube 8. The movement direction of the composite algae extract is as shown in FIG. Fig.19 As indicated by the arrow; When the piston rod of the right cylinder 16 is fully extended, all the composite algae extracts in the sampling tube 18 are squeezed into the docking tube 8. At this time, the composite algae extracts in the upper layer area, the composite algae extracts in the middle layer area, and the composite algae extracts in the lower layer area are squeezed into the three docking tubes 8 respectively. At the same time, the composite algae extracts submerge the detection head 10 of the concentration detector 9; S43, after being stationary for a period of time, the concentration detectors 9 in the three docking tubes 8 respectively detect the concentrations of the compound algae extract in the upper layer, the compound algae extract in the middle layer, and the compound algae extract in the lower layer, and the concentration detectors 9 transmit the concentration signals to the display screen of the controller; Among them, it can be known from this step S4 that the worker only needs to control the piston rod of the feed cylinder 6 to extend to the right, so that the docking tube 8 is sleeved on the outside of the plugging head 23, and the rod 11 in the docking tube 8 pushes the end cover 25 to the right, thereby connecting the docking tube 8, the connecting pipe 19 and the sampling tube 18 to each other; then, control the piston rod of the right cylinder 16 to extend to the left, so that the slip ring 20 squeezes the composite algae extract in the sampling tube 18 into the docking tube 8; finally, the concentration detectors 9 in the three docking tubes 8 respectively detect the concentrations of the composite algae extract in the upper area, the composite algae extract in the middle area, and the composite algae extract in the lower area, thereby detecting the concentration of the composite algae extract in the temporary storage tank 1.

[0029] It can be seen that the detection device can detect the concentrations of the composite algae extract in the upper area, the composite algae extract in the middle area, and the composite algae extract in the lower area at the same time. Compared with the detection method in the workshop, there is no need to detect the concentrations of the composite algae extract in the upper area, the composite algae extract in the middle area, and the composite algae extract in the lower area in three steps respectively, thereby simplifying the process, which not only greatly reduces the work intensity of the workers, but also greatly shortens the sampling time of the composite algae extract, thereby greatly improving the detection efficiency of the concentration of the composite algae extract.

[0030] S5. The worker calculates the average value of the concentration of the compound algae extract in the upper region, the concentration of the compound algae extract in the middle region, and the concentration of the compound algae extract in the lower region. The average value is the concentration of the compound algae extract in the temporary storage tank 1.
