Description

Technical Field

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

[0002] Powdered cosmetics are a type of cosmetics that are mainly in the form of powder. Sampling and testing of powdered cosmetics is an important step to ensure product quality, safety and compliance with relevant standards. It usually includes physical, chemical and microbiological tests on the product. Sampling and testing of powdered cosmetics includes sampling and testing in the laboratory and sampling and testing on the production line. Sampling and testing of powdered cosmetics on the production line requires continuous large-scale sampling. However, the existing sampling and testing devices for powdered cosmetics used on the production line have certain problems during use:

[0003] 1. During the sampling and testing of powdered cosmetics on the production line, in order to ensure the accuracy of the test results and reduce the error of the test results, the same batch of powdered cosmetics produced needs to be randomly sampled and tested multiple times, and the samples taken multiple times can be used as a control group. However, the existing equipment usually performs single-point sampling each time, and each sample is not compared with a control group, thereby reducing the accuracy of the sample inspection at each time. After sampling, the samples need to be funneled into the sampling bottle for sealing. However, when powdered cosmetics come into contact with humid air, they are prone to agglomeration, causing the powdered cosmetics to adhere to the funnel. The powdered cosmetics remaining on the funnel will interfere with the samples of the next batch, reducing the accuracy of sampling and testing.

[0004] 2. During the sampling and inspection process on the production line of powdered cosmetics, it is necessary to use sampling bottles to store the powdered cosmetics taken out. Since continuous large-scale random inspections are required on the production line, in order to ensure the efficiency of sampling and inspection, it is necessary to realize continuous automatic switching of the sampling bottles. During switching, in order to ensure that the samples accurately fall into the sampling bottles, the sampling bottles need to be accurately positioned. However, after the sampling bottles of existing equipment are accurately positioned, there is a distance between the sampling bottles and the hopper, resulting in the samples being exposed to the air during the dropping process, affecting the test results. In addition, the production date, production batch, and content of the powdered cosmetics need to be marked, so it is necessary to use a labeling machine to label the sampling bottles. However, the labeling process of existing equipment is usually before or after the sample is bottled, and the bottling action and the labeling action are independent of each other. The two are performed one after the other, and the work efficiency is low. Summary of the invention

A gear ring 95 is fixedly connected to the bottom of the connecting pins 94. A number of scraping plates 92 for scraping the hopper 91 are evenly installed on the inner wall of the rotating ring 93. A No. 2 rack 96 meshing with the gear ring 95 is fixedly connected to the front side of the connecting plate 12.

[0047] When the sampling bottle is labeled, the sampling bottle is raised to the specified position. Under the precise positioning and stable clamping of the clamping and lifting mechanism 4, the sampling bottle is accurately raised to the bottom of the hopper 91, and the two are aligned. At this time, under the squeezing of the hopper 91, the self-sealing top cover inside the sampling bottle is pushed open, and the bottom end of the hopper 91 extends into the sampling bottle. In the initial state, the material head 233 always keeps in contact with the sealing ring, which effectively ensures the sealing of the conveying pipe 1. The receiving groove 234 is located on the outside of the conveying pipe 1 and does not Entering into the conveying pipeline 1, the servo motor 712 is started at this time, and the servo motor 712 drives the second spur gear 711 to rotate, indirectly drives the two fourth spur gears 717 to rotate synchronously, and then drives the linkage gears 210 on the left and right sides of the fourth spur gear 717 to rotate synchronously, drives the transmission shaft 212 and the first connecting rod 213 thereon to rotate synchronously, and then drives one end of the second connecting rod 214 to rotate along the axis of the transmission shaft 212, thereby driving the slider 215 to slide back and forth along the slide rail 217, synchronously driving the bearing plate 232 The mounting rod 231 thereon reciprocates left and right, and then synchronously drives the material taking head 233 to extend into the conveying pipe 1 to take the material, and then retracts from the conveying pipe 1 after taking the material. The sealing ring is made of silicone and has elasticity. The sealing ring is used to prevent the powdered cosmetics from leaking from the conveying pipe 1. After taking the material, as the mounting rod 231 moves away from the conveying pipe 1, it synchronously drives the fixed head 236 and the guide slide bar 235 away from the conveying pipe 1, and then the guide slide bar 235 slides inside the guide slide groove 222, and the guide slide groove 222 is The guide slide 235 is composed of a straight section and an arc section. When the guide slide bar 235 passes through the arc section, it drives the guide slide bar 235 to flip, and then drives the fixed head 236 to flip, and then drives the mounting rod 231 and the material taking head 233 thereon to flip, so that the powdered cosmetics in the material taking head 233 leak out, realizing the reciprocating cycle of material taking and flipping and discharging, and realizing that the powdered cosmetics are sampled and directly fall into the sampling bottle, avoiding the direct exposure of the powdered cosmetics sample to the air, avoiding the contamination of the powdered cosmetics sample, and improving the accuracy of detection.

[0048] The powdered cosmetics taken out are leaked into the hopper 91 through the flipping of the material taking head 233, and then leaked into the inside of the sampling bottle, realizing the automatic taking out and bottling of the powdered cosmetics. Then, under the reciprocating motion of the slider 215, the reciprocating motion of the connecting plate 12 and the second rack 96 thereon is driven, thereby driving the gear ring 95 to reciprocate, and then driving the connecting pin 94 and the rotating ring 93 thereon to reciprocate, and then driving the rotating ring 93 to reciprocate to scrape the powder attached to the top of the hopper 91, realizing the hopper 91. Automatic cleaning ensures that each sample of powdered cosmetics completely enters the sampling bottle, ensures that each sampling does not interfere with each other, avoids the residual powdered cosmetics sample from affecting the test results, and improves the accuracy of the test. When the material is taken, the output end of the hydraulic cylinder 11 descends, and the top cover on the inside of the sampling bottle is automatically closed. Finally, the sampling bottle is lowered and placed on the circular conveyor belt 5, and the clamping and lifting mechanism 4 releases the clamping of the sampling bottle, and then the circular conveyor belt 5 transports the sampled material to the inspection equipment for inspection.

[0049] Working principle: During use, the present invention conveys the empty sampling bottle to the bottom of the self-cleaning mechanism 9 through the circular conveyor belt 5. At this time, the blocking mechanism 8 limits the empty sampling bottle. At this time, the clamping and lifting mechanism 4 clamps and fixes the sampling bottles on both sides in an integrated and synchronous manner, thereby realizing the precise positioning and stable clamping of the sampling bottle. After the clamping is stable, the sampling bottle is driven to rise to the bottom of the self-cleaning mechanism 9. During the lifting process, the labeling mechanism 3 automatically labels the sampling bottle. The labeling mechanism 3 is integrated 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 bottle is raised to the bottom of the self-cleaning mechanism 9, the hopper 91 opens the self-sealing top cover inside the sampling bottle, and then the flipping and taking mechanism 2 is used to take out the powdered cosmetics. Reciprocating material taking, two flipping material taking mechanisms 2 synchronously and randomly take materials, and each time the samples taken out are compared with each other, which reduces the detection error. After taking the materials, during the retraction process, the material taking head 233 automatically turns over and drops the powdered cosmetics directly into the sampling bottle for storage, avoiding the pollution caused by the powdered cosmetics taken out being directly exposed to the air, thereby improving the accuracy of the detection. During the reciprocating material taking process, the self-cleaning mechanism 9 realizes automatic cleaning of the hopper 91, ensuring that each sample of powdered cosmetics completely enters the sampling bottle, ensuring that each sampling does not interfere with each other, avoiding the residual powdered cosmetics sample from affecting the detection result, and further improving the accuracy of the detection. After taking the materials, the taken materials are conveyed to the inspection equipment for inspection through the ring conveyor belt 5.
