As a technical optimization scheme of the invention, the outer parts of the first roller rod 17 and the second roller rod 26 are respectively sleeved with a sponge layer, and the bottom of the test tube channel 16 is connected with the buffer sleeve 12 in a penetrating way. The buffer sleeve 12 is not easy to fall down and is not damaged by collision when the test tube moves downwards.
When the invention is used, the rotating shaft 3 on the top plate 1 is connected with driving equipment on the sorting machine, and the fixed rods 11 on two sides of the bottom plate 13 are connected and fixed with the sorting machine. The test tubes to be sorted are placed in respective loading ledges 2, a plurality of test tubes are loaded vertically in one loading ledge 2, and the bottoms of the test tubes are directed downward when loaded. After the test tube is placed into the loading frame 2, the clamping ring 5 is continuously extruded and moved towards one end, two sides of the test tube are limited by the protection pad 7, the test tube is not easy to shake and damage, good stability can be maintained, and the follow-up clamping ring 5 is convenient to push. The test tube is always placed above the perforation 9 under the pushing of the spring 4, and the test tube is limited by the pressing plates 8 at the two sides above the perforation 9 and cannot fall down.
When test tubes need to be sorted, the rotating shaft 3 drives the top plate 1 to intermittently rotate, the loading frame 2 can sequentially move by a preset angle every time, and the plurality of loading frames 2 can continuously rotate above the lower test tube channel 16, so that test tubes inside the loading frames 2 can be closely matched with the test tube channel 16 below. After the rotation of the top plate 1 is stopped, the upper through holes 9 and the lower test tube channels 16 are in one-to-one correspondence, and the centers are on the same straight line. The inside first roller 17 of test tube passageway 16 all keeps the rotation state, and the electronic slider of top drives clamp plate 8 and reciprocates, and then drives the test tube and move down, if the diameter of test tube is less than the internal diameter of below test tube passageway 16, then can enter into the inside of test tube passageway 16, if the test tube diameter is greater than the internal diameter of below test tube passageway 16, then the test tube can not enter into the inside of test tube passageway 16. If the diameter of the test tube entering the test tube channel 16 is not matched with that of the test tube channel 16, the outer wall of the test tube cannot be contacted with the rotating first roller rod 17, so that the test tube cannot be stirred downwards, the test tube which does not match with the test tube channel 16 and the test tube which cannot enter the test tube channel 16 can return to the original position upwards under the drive of the electric sliding block of the pressing plate 8. If the test tube entering the test tube channel 16 accords with the standard of the inner diameter of the test tube channel 16, the outer wall of the test tube can be uniformly contacted with the rotating four first roller rods 17, and the first roller rods 17 drive the test tube to move downwards of the test tube channel 16. After the first roller rod 17 is extruded by the test tube, the second elastic telescopic rod 22 is compressed by pressure, so that the push rod 20 is driven to be abutted with the first start-stop switch 21, the telescopic column 14 stretches upwards, the telescopic end stretches out from the inside of the mounting groove 15 and is abutted with the second start-stop switch 23 above, and the second roller rod 26 corresponding to the side face of the pressing plate 8 rotates. After the second roller rod 26 rotates, the test tube is pushed downwards, the test tube is moved out of the loading frame 2 under the drive of the second roller rod 26 and the first roller rod 17, passes through the test tube channel 16 and enters the buffer sleeve 12, and finally enters the collecting device below through the buffer of the buffer sleeve 12 for collection.
After the test tube is separated from the interior of the test tube channel 16, the second elastic telescopic rod 22 is extended, and the push rod 20 is separated from the first start-stop switch 21. The telescopic column 14 is retracted into the inside of the mounting groove 15 and is disengaged from the second start-stop switch 23, and the second roller bar 26 stops rotating. The spring 4 pushes the snap ring 5 inside the loading frame 2 towards the end of the perforation 9. So that the test tubes inside the loading frame 2 can enter between the two pressing plates 8 individually and in sequence and can move downwards from the perforations 9. Along with the continuous rotation and the stop of roof 1, through many times of tests, the test tube in loading frame 2 can sort according to the diameter, sorts accurate and convenient, and the test tube is not fragile in the letter sorting process. After the test tubes in the loading frame 2 are sorted, the test tubes to be sorted can be sorted again after being loaded again.
