It should be noted that, because the chips are all turned, the chips of each type are often stacked in layers, so that the waste can exist in a concentrated area on the chip conveyor 1, which is convenient for sorting. When the metal component detector 16 detects a waste material segment, the waste material segment is transmitted to the control module 2 through the starting point time and the end point time of the metal component detector 16, the control module 2 controls the telescopic inclined plate to extend out in a corresponding time period, and simultaneously controls the material barrel translation mechanism to move the waste material barrel 17 to the lower side of the telescopic inclined plate, the telescopic inclined plate cuts off the scrap material and is thrown to a scrap material collecting route of the material collecting barrel 4 by the scrap material conveyor 1, so that the waste material segment falls into the waste material barrel 17 through the telescopic inclined plate, after the cutting time period is finished, the telescopic inclined plate retracts, the titanium or TC4 titanium alloy scrap material segment normally falls back into the material collecting barrel 4, and the classified collection of the scrap material is finished.

It should be noted that, the operator recovers the sample barrel 8 on time according to the sampling time of the scraps to complete sampling, so as to facilitate subsequent detection, and after the sample barrel 8 is recovered, a new sample barrel 8 needs to be placed below the telescopic inclined plate, so as to facilitate normal sampling next time.
In this embodiment, a threshold value of the weighing sensor 6 is set in the microcontroller 9, the threshold value is the sum of the self weight of the material collecting barrel 4 and the allowable collection weight of a barrel of scrap material, when the detection result of the weighing sensor 6 is greater than or equal to the threshold value, it indicates that the material collection of the current material collecting barrel 4 is completed, and the microcontroller 9 controls the rotation of the turntable main body 3, so that the next material collecting barrel 4 on the turntable main body 3 moves to the lower side of the scrap material conveyor 1. In the rotating process of the rotary table main body 3, the scrap conveyor 1 stops feeding or collects scraps in the time period into the waste material barrel 17 by utilizing the extension of the telescopic inclined plate, so that the scraps are prevented from polluting the working environment.
In this embodiment, because the densities of the scraps of different types are different, the weight of the scraps of different types that can be borne by the collecting barrel 4 is different, and when the metal component detector 16 detects what type of the target collected scraps in the batch is, the microcontroller 9 automatically matches the corresponding threshold of the weighing sensor 6, so as to avoid the problem of insufficient or excessive collecting amount.
The scrap materials conveyed by the scrap material conveyor 1 are automatically collected through the scrap material collecting rotary disc, so that an operator does not need to operate in real time at a scrap material collecting position, and only needs to process the scrap materials at a material collecting station after the material collecting barrel 4 on the scrap material collecting rotary disc is completely full of the scrap materials, the utilization efficiency of human resources is greatly improved, and the production cost is saved;

when the metal component detector (16) detects the waste material section, executing a fourth step;
when the material section to be recovered needs to be sampled, executing a fifth step;
step three, collecting the material section to be recovered:
301, obtaining start-stop time periods [ Ti1, ti2] of the ith material section to be recovered passing through a detection point of a metal component detector (16), wherein i is the number of the material sections to be recovered, ti1 is a time point when the head end of the ith material section to be recovered passes through the detection point of the metal component detector (16), and Ti2 is a time point when the tail end of the ith material section to be recovered passes through the detection point of the metal component detector (16);
step 302, in a time period [ Ti1+ t, ti2+ t ], keeping the retraction state of the telescopic inclined plate, and throwing the ith material section to be recovered into a material collecting barrel (4) by a scrap conveyor (1) to finish the collection of the ith material section to be recovered; wherein t is the compensation time for the movement of the scraps;
step four, collecting a waste section:
step 401, obtaining a start-stop time period [ Tj1, tj2] when the jth waste material segment passes through a detection point of a metal component detector (16), wherein j is the number of the waste material segment, tj1 is a time point when the head end of the jth waste material segment passes through the detection point of the metal component detector (16), and Tj2 is a time point when the tail end of the jth waste material segment passes through the detection point of the metal component detector (16);
step 402, controlling the charging basket translation mechanism to move the waste charging basket (17) to the position below the discharging end of the telescopic inclined plate, and simultaneously controlling the telescopic inclined plate to extend out, so that the telescopic inclined plate can cut off scraps and throw the scraps from the scrap conveyor (1) to a scrap collecting route of a section to be recovered of the collecting basket (4) at the time Tj1+ t, and the waste sections can fall back into the waste charging basket (17) through the telescopic inclined plate;
step 403, controlling the telescopic inclined plate to retract at the time Tj2+ t to complete sorting and collection of the jth waste material section;
step five, sampling of the material section to be recovered:
in the time quantum [ Ti1, ti2], control storage bucket translation mechanism will sample bucket (8) move to the discharge end below of telescopic swash plate, control afterwards telescopic swash plate stretches out, and the intercepting is waited to retrieve in material section to sample bucket (8), and after the sample settlement time, control telescopic swash plate is retracted, wait to retrieve the material section and throw again to collecting vessel (4) in, accomplish the sample of waiting to retrieve the material section.
