Description

Technical Field

[0001] The invention relates to the technical field of industrial production, in particular to a centrifugal separation device for producing ultraviolet absorbers. Background Art

[0002] Ultraviolet absorber is a kind of light stabilizer. When added to polymer materials, it can absorb ultraviolet rays in sunlight, protect the polymer materials from ultraviolet radiation, and prevent photoaging of the materials. In addition, it can also be processed onto the surface of textiles to prepare textiles with ultraviolet protection functions. It can also be used to prepare some skin care products with anti-ultraviolet functions to avoid ultraviolet damage to human skin.

[0003] The current centrifugal device for ultraviolet absorber centrifugation usually directly sets a plurality of groups of jacks on the rotating disk, then pours the mixed solution containing ultraviolet absorber into the test tube and inserts it into the jacks, and then centrifuges the mixture in the test tube by rotating the rotating disk at high speed. However, there is usually only one row of jacks, and the mixed solution that can be centrifuged each time is very limited, which cannot increase the amount of mixed solution that can be centrifuged each time by the device, and improve the production efficiency of ultraviolet absorber; and the current centrifugal device is usually provided with only one group of rotating disks, and the stability of the rotation of the rotating disk is completely provided by the bearings at the driving shaft, which can provide very limited stability, and cannot further improve the stability of the rotating disk during rotation; at the same time, since the diameter of the jacks on the rotating disk is mostly fixed, it is often only suitable for test tubes with fixed diameters, which also greatly limits the scope of application of the centrifugal device, and cannot completely guarantee the stability of the test tube in the jack.

[0019] 3. The present invention first controls the dual-axis motor to drive the two groups of worms to rotate clockwise, and drives the two groups of threaded rods to rotate synchronously through the transmission of the worm and the worm wheel.

The internal threaded tube 803 is forced to gradually rise on the outside of the threaded rod 801 by the thread effect, and the first mounting plate 10 is gradually lifted up. The first mounting plate 10 first lifts up the first rotating platform 14, and after the supporting ring 802 reaches the bottom of the second mounting plate 17, the second rotating platform 19 is lifted up, so that there is a larger gap between the first rotating platform 14, the second rotating platform 19 and the third rotating platform 24. , which is convenient for the operator to insert multiple test tubes containing the ultraviolet absorber mixture into the placement slots 16 on the first rotating table 14, the second rotating table 19 and the third rotating table 24 respectively, and then control the dual-axis motor 806 to drive the two groups of worm gears 805 to rotate counterclockwise, and stack them on the first rotating table 14, the second rotating table 19 and the third rotating table 24 again, and then close the top cover 2 and the front cover 6, and control the servo motor 22 to drive the first rotating table 14, the second rotating table 19 and the third rotating table 24 to rotate synchronously in the same direction, so that the ultraviolet absorber mixture in the test tube can be centrifuged.

[0044] Embodiment 2, as Figure 1-10As shown, after the test tubes are inserted into each group of placement slots 16 one by one, the dual-axis motor 806 is then controlled to drive the two groups of worms 805 to rotate counterclockwise, and the first rotating platform 14 and the second rotating platform 19 are synchronously lowered. During the process, the slide bar 20 slides downward on the inner side of the limit ring 18, and the bottom of the second rotating platform 19 first contacts the top of the third rotating platform 24, and then the bottom of the first rotating platform 14 contacts the top of the second rotating platform 19, and finally the first mounting plate 10 is lowered to force the first rotating platform 14 to tightly abut against the top of the second rotating platform 19, and the second rotating platform 19 will tightly abut against the third rotating platform 2 4, during which the bottom of the first rotating platform 14 presses the corresponding ring 901 to slide downward on the fixed tube 907, the spring 906 is shortened by force and stores elastic potential energy, and the connecting rod 902 pushes the push rod 904 to approach the inside of the placement groove 16, and the rubber pad 903 at the top of the push rod 904 will abut against the surface of the test tube, holding the test tube tightly, thereby improving the stability of all the test tubes in the placement groove 16, the disc 13 will abut against the top group of rings 901, the first rotating platform 14 will abut against the middle group of rings 901, and the second rotating platform 19 will abut against the bottom group of rings 901.

[0045] Embodiment 3, as Figure 2-10 As shown, the dual-axis motor 806 is controlled to drive the two groups of worms 805 to rotate clockwise, and the two groups of threaded rods 801 are driven to rotate synchronously through the transmission of the worm 805 and the worm wheel 807. The internal threaded tube 803 is forced to gradually rise on the outside of the threaded rod 801 by the thread effect, and the first mounting plate 10 is gradually lifted up. The first mounting plate 10 first lifts up the first rotating platform 14, and after the supporting ring 802 reaches the bottom of the second mounting plate 17, the second rotating platform 19 is lifted up, so that there is a space between the first rotating platform 14, the second rotating platform 19 and the third rotating platform 24. In a larger gap, during the process, the first slider 29 slides inside the first slide groove 34 and the movable rod 28 rises inside the rotating tube 23, and the second slider 31 slides inside the second slide groove 33, so that even after the first rotating table 14 and the second rotating table 19 are raised to a higher height, the first rotating table 14, the second rotating table 19 and the third rotating table 24 still rotate synchronously and do not rotate individually, which helps each group of blocks 11 to be accurately inserted into the corresponding slots 15 after the first rotating table 14, the second rotating table 19 and the third rotating table 24 are closed again.

[0046] Working principle: before use, connect the device to the power supply, first unscrew the butterfly screw 5 to release the fixing effect of the butterfly screw 5 on the plug board 4, then open the top cover 2 and the front cover 6, and then control the dual-axis motor 806 through the control panel 1 to drive the two sets of worm 805 to rotate clockwise, and drive the two sets of threaded rods 801 to rotate synchronously through the transmission of the worm 805 and the worm wheel 807, and use the thread effect to force the internal threaded tube 803 to gradually rise on the outside of the threaded rod 801, and gradually lift up the first mounting plate 10. The first mounting plate 10 first raises the first rotating platform 14, and after the supporting ring 802 reaches the bottom of the second mounting plate 17, the second rotating platform 19 is lifted and raised, so that there is a large gap between the first rotating platform 14, the second rotating platform 19 and the third rotating platform 24. During the process, the first slider 29 slides inside the first slide groove 34, and the second slider 31 in the second The inside of the slide groove 33 slides. At this time, the operator can insert multiple groups of test tubes with ultraviolet absorber mixture into all the placement grooves 16 by rotating the first rotating table 14, the second rotating table 19 and the third rotating table 24, and then control the dual-axis motor 806 to drive the two groups of worm gears 805 to rotate counterclockwise, so that the first rotating table 14, the second rotating table 19 and the third rotating table 24 are stacked together again, and the block 11 is re-engaged in the inside of the slot 15, and then the top cover 2 and the front cover 6 are closed, and the servo motor 22 is controlled to drive the third rotating table 24 to rotate. Since the first rotating table 14, the second rotating table 19 and the third rotating table 24 are connected by the block 11 and the slot 15, when the third rotating table 24 rotates, it will drive the first rotating table 14 and the second rotating table 19 to rotate synchronously in the same direction, so as to centrifuge the ultraviolet absorber mixture in the test tube.
