Description

Technical Field

[0001] This utility model relates to the field of particle size detection equipment technology, and in particular to a particle size detection and analysis instrument for water-repellent and oil-repellent finishing agents. Background Technology

[0002] In the production and processing of outdoor clothing fabrics, water-repellent and oil-repellent finishing agents are widely used. They can endow materials with excellent water-repellent and oil-repellent properties, enhance the use value and applicable scenarios of the materials. The particle size and distribution of water-repellent and oil-repellent finishing agents are one of the core indicators affecting their performance. Finishing agents with unqualified particle size will not only lead to poor water-repellent and oil-repellent effects on the materials, but may also cause problems such as uneven coating and easy peeling, which seriously affect product quality. Laser diffraction is usually used to test finishing agents.

[0003] Since water- and oil-repellent finishing agents can agglomerate due to surface tension or settle rapidly due to density differences, resulting in uneven local particle distribution, the particle size detection data is affected, causing the detection results to deviate from the true particle size state of the sample, reducing the accuracy and repeatability of the data. In view of the above reasons, this application proposes a particle size detection and analysis instrument for water- and oil-repellent finishing agents. Utility Model Content

The damping pad 3 is made of silicone and has honeycomb pores distributed within it. The sample cell 5 is movably mounted above the placement area 2, and a stirring structure 7 is provided within the sample cell 5. The stirring structure 7 is used to prevent sample agglomeration or sedimentation, ensuring the accuracy of the test results. The stirring structure 7 includes a drive motor 701 and a PLC 704. A stirring shaft 702 is fixedly installed at the output end of 701. The two ends of the stirring shaft 702 are movably connected to the inner walls of both sides of the sample cell 5. The sample cell 5 has through holes and mounting holes on both sides. Bearings are fixedly installed in both the through holes and the mounting holes. The inner ring of the bearing is fixedly sleeved on the stirring shaft 702. A sealing element is provided on the inner wall of the through hole to improve the sealing performance of the through hole and prevent sample leakage. Multiple spiral stirring blades 703 are fixedly installed on the outside of the stirring shaft 702. During the detection, the speed of the drive motor 701 is controlled by the PLC 704. The drive motor 701 drives the stirring shaft 702, and the stirring shaft 702 drives the multiple spiral stirring blades 703. This can effectively prevent sample agglomeration and sedimentation and ensure the accuracy of the detection data. Reference Figure 4-6As shown, the top of the placement area 2 is provided with two positioning structures 8. The positioning structure 8 includes a mounting box 801. A column 802 is fixedly provided below the mounting box 801. The bottom of the column 802 is fixedly connected to the placement area 2. A locking frame 803 is movably provided on one inner wall of the mounting box 801. The locking frame 803 is composed of a locking rod and a locking hook. A connecting seat 805 is movably provided on the outside of the locking frame 803. A spring 806 is fixedly provided on one inner wall of the mounting box 801. The other end of the spring 806 is in contact with the locking frame 803. A top rod 804 is movably provided on one side of the mounting box 801. A push-pull rod 807 is movably provided inside the mounting box 801. Multiple locking blocks 815 are fixedly provided on the outside of the push-pull rod 807. The sides of the locking hook and locking blocks 815 that are close to each other are provided with parallel inclined surfaces. A connecting rod 808 is movably provided at one end of the push-pull rod 807. A pressure plate 809 is movably provided at the end of the connecting rod 808 away from the push-pull rod 807. Furthermore, a disc 811 is fixedly provided at the end of the connecting rod 808 away from the push-pull rod 807. A limiting groove 810 is provided on the pressure plate 809, and the limiting groove 810 and the disc 811 are movably connected. A sliding groove is provided on the front of the limiting groove 810. A slider is provided on the side of the disc 811 away from the connecting rod 808, and the slider is movably connected to the sliding groove. A connecting post 812 is rotatably provided at the end of the connecting rod 808 near the push-pull rod 807. A screw is provided on the side of the connecting post 812 that is close to the push-pull rod 807. The threaded rod 813 and the internal threaded hole 814 are compatible. The connection post 812, the internal threaded hole 814 and the threaded rod 813 can be set to make fine adjustments to the position of the pressure plate 809, compensate for the play caused after the locking block 815 of the locking frame 803 is locked, and make the pressure plate 809 fit more tightly with the sample cell 5. The positioning structure 8 can realize the positioning of the sample cell 5 and prevent the sample cell 5 from shifting during the operation of the drive motor 701.

[0022] In this embodiment, the damping pad 3 is used to reduce the vibration generated by the sample cell 5 during the operation of the drive motor 701. During testing, the sample is introduced into the sample cell 5, and then two push-pull rods 807 are pushed simultaneously. The two push-pull rods 807 drive the pressure plate 809 and multiple locking blocks 815. The inclined surface of the locking block 815 presses against the inclined surface of the locking hook, and the locking hook drives the locking rod to press against the spring 806. When the two inclined surfaces separate, the spring 806 causes the locking frame 803 to reset and lock onto the locking block 815, realizing the one-way positioning of the push-pull rod 807. When the pressure plate 809 is completely in contact with the sample cell 5, the push-pull rod 807 can be stopped. If the distance between the pressure plate 809 and the sample cell 5 is insufficient to allow the push-pull rod 807 to advance one step, one hand supports the bottom of the pressure plate 809 to limit the angle of the pressure plate 809, and the other hand rotates the connecting column 812 counterclockwise. The connecting column 812 moves away from the push-pull rod 807 and drives the pressure plate 809. When one side of the pressure plate 809 is in contact with the sample cell 5, the connecting column 812 stops rotating to position the sample cell 5. Then, the drive motor 701 is started, which drives the stirring shaft 702. The stirring shaft 702 then drives the spiral stirring blade 703 to rotate, stirring the sample to prevent sample agglomeration or sedimentation. If the sample cell 5 needs to be removed for cleaning, the two push rods 804 are pushed inward, causing the locking frame 803 to rotate and separate from the locking block 815. Then, the push-pull rod 807 is pulled outward to separate the pressure plate 809 from the sample cell 5. Then, the two pressure plates 809 are pulled away to their limits, and then the sample cell 5 is pulled outward to complete the disassembly.

[0023] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
