Description

Technical Field

[0001] The utility model relates to the technical field of material detection, in particular to an ultrapure PFA sampling mechanism. Background Art

[0002] Ultrapure PFA is a special high-performance polymer belonging to the PFA family. PFA itself is a high-temperature plastic similar to polytetrafluoroethylene, with excellent chemical stability, thermal stability, and electrical insulation.

However, in the case of large batches or high-frequency sampling, manual operation increases labor and is inefficient, which not only increases costs but may also limit the frequency and quantity of sampling.

[0004] Therefore, the utility model provides an ultrapure PFA sampling mechanism. Utility Model Content

[0010] As a preferred embodiment, the bottom end of the frame is fixedly connected to the support frame.

[0011] The technical effect of adopting the above technical solution is to ensure that the frame and the detector, ultraviolet lamp and other components at the top remain in a fixed position during operation.

[0013] The technical effect of adopting the above technical solution is that the movement and position of the sample or the detector can be controlled, thereby realizing an automated sampling process.

[0014] As a preferred embodiment, the bottom end of the mounting block is fixedly connected to the support frame.

[0015] The technical effect of adopting the above technical solution is to ensure the stability of the cylinder during operation.

[0016] As a preferred embodiment, the top end of the sliding rod is slidably connected to the sliding groove.

[0017] The technical effect of adopting the above technical solution is to achieve accurate sliding of the slide bar to a specified working position during sliding.

[0018] Compared with the prior art, the advantages and positive effects of the present invention are:

[0019] By setting up the sampling detection component and the differentiation component structure, the detector uses the specific wavelength of light emitted by the ultraviolet lamp to conduct in-depth analysis of the sample, which can accurately detect the composition and characteristics of the sample, and perform efficient coordination and data processing through the controller. In addition, when the test results show the classification of the sample, the precise coordination of the slide rod and the slide groove driven by the cylinder enables the classification plate to move as needed, effectively classifying and collecting defective products in the collection box. This automated design reduces dependence on manual operation, which not only reduces sample processing errors caused by human error, but also reduces the labor intensity of staff. Secondly, the automated classification and collection system also greatly improves the efficiency and accuracy of sampling, while also reducing the risk of cross contamination.

Two support rods 22 are fixedly connected on both sides of the frame 21. The two support rods 22 not only play a supporting role, but also carry the installation of the detector 23. First, the ultraviolet lamp 24 can emit light of a specific wavelength, which is helpful for in-depth detection and analysis of the sample. Then the detector 23 is installed on the top of the support rod 22. This device can accurately detect the various components and characteristics in the sample and transmit them. The controller 25 is responsible for controlling the operation and coordination of each component. Through the controller 25, the user can easily operate the entire assembly and obtain the test results. In addition, a connecting rod 28 is fixedly connected to the top of the support frame 1. The inner side of the connecting rod 28 is rotatably connected to a classification plate 29. This classification plate 29 can automatically classify the samples according to different test results, greatly improving the detection efficiency.

[0031] Furthermore, if Figure 1-Figure 2 As shown, the driving end of the motor 26 is fixedly connected to the conveyor belt 27. The motor 26 is the power source of the entire device. It is installed at one end of the frame 21 and is responsible for providing stable and continuous power to the entire conveying system. Driven by the motor 26, the conveyor belt 27 can continue to operate. The conveyor belt 27 is installed on the outside of the frame 21 to form a closed loop structure.

[0032] In order to realize the differentiated storage of the detected products, Figure 1 、 Figure 3 and Figure 4As shown: In this solution, the distinguishing component 3 includes a mounting block 31, the bottom end of the mounting block 31 is fixedly connected to the support frame 1, the top of the mounting block 31 is installed with a cylinder 32, the driving end of the cylinder 32 is rotatably connected to the slide rod 33, the top of the classification plate 29 is provided with a slide groove 34, the top of the slide rod 33 is slidably connected to the slide groove 34, the top of the support frame 1 is fixedly connected to the collection box 35, the mounting block 31 carries the stability of the entire device, the mounting block 31 is firmly fixed to the support frame 1, ensuring the stability of the entire device, the cylinder 32 is the power source of the distinguishing component 3, the driving end of the cylinder 32 is connected to the slide rod 33 are connected by precise rotation, which ensures that the slide bar 33 can move flexibly and accurately under the drive of the cylinder 32.

[0035] When in use: First, the motor 26 serves as the power source for the entire device and is installed at one end of the frame 21, responsible for providing stable and continuous power for the conveying system. Then, the driving force of the motor 26 is transmitted to the outer conveyor belt 27 through the frame 21, so that the conveyor belt 27 forms a closed ring structure and continues to operate. Thus, the conveyor belt 27 transports the sample to the detection area and hands it over to the detector 23 installed at the top of the support rods 22 on both sides of the frame 21 for detection. At this time, the ultraviolet lamp 24 at the bottom of the detector 23 emits light of a specific wavelength, which helps to conduct in-depth detection and analysis of the sample.

Subsequently, according to the detection results, the classification plate 29 connected to the inner rotation will automatically classify the samples, and then the cylinder 32 will be started. Driven by the cylinder 32, the slide rod 33 will slide on the slide groove 34 and then drive the classification plate 29 to be lowered toward the collection box 35. At this time, the defective products can fall into the collection box 35 to achieve the classification effect.
