The clamping and lifting mechanism synchronously clamps and lifts two sampling bottles, and through the extrusion of the labeling component by the pressurizing driving component, synchronous labeling of the two sampling bottles is realized. The clamping and lifting mechanism and the labeling mechanism are integrally linked.

Description

Technical Field

[0001] The present invention relates to the technical field of sampling inspection equipment, and particularly to a sampling inspection device for powdery cosmetics. Background Art

[0002] Powdery cosmetics are a type of makeup product mainly in powder form. Sampling inspection of powdery cosmetics is an important step to ensure product quality, safety and compliance with relevant standards. It usually includes tests on the product in aspects such as physics, chemistry and microbiology. Sampling inspection of powdery cosmetics includes sampling inspection in the laboratory and sampling inspection on the production line. During the sampling inspection of powdery cosmetics on the production line, continuous large - batch sampling inspection is required. However, there are certain problems in the existing sampling inspection devices for powdery cosmetics used on the production line during use:

[0003] 1. During the process of sampling inspection of powdery cosmetics on the production line, in order to ensure the accuracy of the inspection results and reduce the error of the inspection results, the same batch of powdery cosmetics produced needs to be randomly sampled and inspected multiple times. The samples taken multiple times can be used as control groups. However, the existing equipment usually takes single - point sampling each time, and there is no control group for comparison between the samples taken each time, thus reducing the accuracy of sample inspection each time. After sampling, it needs to be leaked into the sampling bottle through a hopper for sealing. However, when powdery cosmetics encounter humid air, they are prone to agglomeration, resulting in the adhesion of powdery cosmetics to the hopper. The powdery cosmetics remaining on the hopper will interfere with the samples of the next batch, reducing the accuracy of sampling detection.

[0004] 2. During the process of sampling inspection on the production line of powdery cosmetics, it is necessary to use sampling bottles to store the taken powdery cosmetics. Since continuous large - batch sampling inspection is required on the production line, in order to ensure the efficiency of sampling inspection, continuous automatic switching of sampling bottles needs to be achieved. When switching, in order to ensure that the sample accurately falls into the sampling bottle, precise positioning of the sampling bottle is required. However, after the sampling bottle of the existing equipment is precisely positioned, there is a certain distance between the sampling bottle and the hopper, resulting in the sample being exposed to the air during the falling process, affecting the detection results. And for different production dates, production batches and contents of powdery cosmetics, labeling is required. Therefore, a labeling machine needs to be used to label the sampling bottles. However, the labeling process of the existing equipment is usually before or after the sample is bottled. The bottling action and the labeling action are independent of each other and are executed successively, with low working efficiency. Summary of the Invention

A second rack 96 meshing with the toothed ring 95 is fixedly connected to the front side of the connecting plate 12.

[0047] After the labeling of the sampling bottle is completed, the sampling bottle rises to the specified position. Under the precise positioning and stable clamping of the clamping and lifting mechanism 4, it is ensured that the sampling bottle accurately rises to the bottom of the leakage hopper 91, achieving the alignment of the two. At this time, under the extrusion of the leakage hopper 91, the self-sealing top cover inside the sampling bottle is pushed open. The bottom end of the leakage hopper 91 extends into the sampling bottle. In the initial state, the material taking head 233 is always in contact with the sealing ring, effectively ensuring the sealing performance of the conveying pipeline 1. The accommodating groove 234 is located outside the conveying pipeline 1 and does not enter the conveying pipeline 1. At this time, the servo motor 712 is started. The servo motor 712 drives the second spur gear 711 to rotate, indirectly driving the two fourth spur gears 717 to rotate synchronously. Then, the linkage gears 210 on the left and right sides of the fourth spur gear 717 are driven to rotate synchronously, driving the transmission shaft 212 and the first connecting rod 213 thereon to rotate synchronously. Immediately, one end of the second connecting rod 214 is driven to rotate along the axis of the transmission shaft 212, thereby driving the slider 215 to slide left and right reciprocally along the slide rail 217, synchronously driving the bearing plate 232 and the mounting rod 231 thereon to move left and right reciprocally. Then, the material taking head 233 is synchronously driven to extend into the conveying pipeline 1 to take material, and after taking the material, it retracts from the conveying pipeline 1. The sealing ring is made of silica gel and has elasticity. The sealing ring is used to prevent the problem of powdered cosmetics leaking from the conveying pipeline 1. After taking the material, as the mounting rod 231 moves away from the conveying pipeline 1, the fixed head 236 and the guiding slide rod 235 are synchronously driven to move away from the conveying pipeline 1. Then, the guiding slide rod 235 slides inside the guiding chute 222. The guiding chute 222 is composed of a straight section and an arc section. When the guiding slide rod 235 passes through the arc section, the guiding slide rod 235 is driven to flip, immediately driving the fixed head 236 to flip, and then driving the mounting rod 231 and the material taking head 233 thereon to flip, so as to leak the powdered cosmetics in the material taking head 233, realizing the reciprocating cycle of taking material and flipping and discharging material, realizing that the powdered cosmetics directly fall into the sampling bottle after sampling, avoiding the direct exposure of the powdered cosmetics sample to the air, and avoiding the situation of the powdered cosmetics sample being contaminated, improving the accuracy of detection.

[0048] The powdered cosmetics taken out are poured into the hopper 91 through the flipping of the material taking head 233, and then fall into the sampling bottle, realizing the automatic taking and bottling of the powdered cosmetics. Then, under the reciprocating movement of the slider 215, the connecting plate 12 and the second rack 96 thereon are driven to reciprocate, thereby driving the toothed ring 95 to rotate reciprocally, then driving the connecting pin 94 and the rotating ring 93 thereon to rotate reciprocally, and then driving the rotating ring 93 to scrape reciprocally to scrape off the powder adhering to the top of the hopper 91, realizing the automatic cleaning of the hopper 91, ensuring that the powdered cosmetic samples taken each time completely enter the sampling bottle, ensuring that each sampling does not interfere with each other, avoiding the influence of the residual powdered cosmetic samples on the test results, and improving the accuracy of the test. When the material taking is completed, the output end of the hydraulic cylinder 11 descends. At this time, the top cover inside the sampling bottle is automatically closed. Finally, the sampling bottle descends and is placed on the annular conveyor belt 5. The clamping and lifting mechanism 4 releases the clamping of the sampling bottle. Subsequently, the annular conveyor belt 5 conveys the taken material to the inspection equipment for inspection.

[0049] Working principle: During the use of the present invention, the empty sampling bottles are conveyed to directly below the self-cleaning mechanism 9 through the annular conveyor belt 5. At this time, the material blocking mechanism 8 limits and blocks the empty sampling bottles. At this time, the clamping and lifting mechanism 4 integrally and synchronously clamps and fixes the sampling bottles on both sides, realizing the precise positioning and stable clamping of the sampling bottles. After stable clamping, the sampling bottles are driven to rise to directly below the self-cleaning mechanism 9. During the rising process, the labeling mechanism 3 automatically labels the sampling bottles. The labeling mechanism 3 is integrally linked with the clamping and lifting mechanism 4, and the labeling action and the lifting action are completed synchronously, with high working efficiency. When the sampling bottles rise to directly below the self-cleaning mechanism 9, the hopper 91 pushes open the self-sealing top cover inside the sampling bottle, and then the reciprocating material taking of the powdered cosmetics is carried out by using the flipping material taking mechanism 2. The two flipping material taking mechanisms 2 take materials synchronously and randomly, and the samples taken each time are used as references for each other, reducing the detection error. During the retraction process after material taking, the material taking head 233 automatically flips, and the powdered cosmetics directly fall into the sampling bottle for storage, avoiding the pollution caused by the taken-out powdered cosmetics being directly exposed to the air, and improving the accuracy of the test. During the reciprocating material taking process, the self-cleaning mechanism 9 realizes the automatic cleaning of the hopper 91, ensuring that the powdered cosmetic samples taken each time completely enter the sampling bottle, ensuring that each sampling does not interfere with each other, avoiding the influence of the residual powdered cosmetic samples on the test results, and further improving the accuracy of the test. After material taking, the taken material is conveyed to the inspection equipment for inspection through the annular conveyor belt 5.
