[0025] Embodiment 1

[0026] The present utility model provides a heavy metal detection device for coating pigments and fillers as shown in Figures 1-5 which includes a spectrometer 1 and a detection placement plate 2 arranged inside the spectrometer 1. A vertical rod 3 is rotatably arranged at the upper end inside the spectrometer 1. The detection placement plate 2 is fixedly sleeved with the vertical rod 3. A plurality of card slots 4 arranged in a circumferentially symmetric manner are formed on the outer side of the detection placement plate 2. Elastic buckle plates 19 are fixedly arranged in the plurality of card slots 4. A cover shell 5 is fixedly sleeved on the outer wall of the spectrometer 1. Through holes are formed on the sides of the cover shell 5 and the spectrometer 1 close to each other. A material cylinder 6 is fixedly penetrated through the top of the cover shell 5. A discharge pipe 7 is communicated with the bottom of the material cylinder 6. A solenoid valve 26 is fixedly sleeved on the pipe wall of the discharge pipe 7. A support frame 8 is fixedly sleeved on the lower end outside the material cylinder 6. A placement hole is formed on the side part of the support frame 8. An annular plate 9 is fixedly arranged at the lower end of the support frame 8;

[0027] A feeding installation mechanism is arranged inside the annular plate 9. The feeding installation mechanism includes two driving rollers 10 rotatably arranged inside the annular plate 9. A motor 11 is fixedly arranged on the outer wall of the annular plate 9. The output end of the motor 11 penetrates into the annular plate 9 and is fixedly connected with the driving roller 10. A transmission belt 12 is sleeved on the roller walls of the two driving rollers 10. A plurality of partition boards 13 arranged at intervals are fixedly arranged on the outer wall of the transmission belt 12. The annular plate 9 is located in the through hole and is arranged in cooperation with the card slot 4. Baffles 23 are fixedly arranged on the front and rear sides of the support frame 8.

[0028] Before detecting the heavy metals inside the coating, the inside of the barrel 6 is filled with the coating, and the discharging is controlled by the discharging pipe 7 and the electromagnetic valve 26. Subsequently, the motor 11 is started, so that the driving roller 10 rotates and drives the conveyor belt 12 to rotate. Subsequently, a plurality of sampling test tubes can be sequentially placed on the conveyor belt 12, and are located between two adjacent partition plates 13, and are laterally limited by the side of the baffle 23 at the same time. When the sampling test tube moves below the discharging pipe 7, the electromagnetic valve 26 opens, so that the coating enters the sampling test tube. When the sampling is completed, the electromagnetic valve 26 is closed. At this time, under the conveying and pushing of the conveyor belt 12 and the partition plate 13, the sampling test tube can be clamped into the clamping groove 4 outside the detection placement disk 2 and is clamped tightly by the elastic clamping plate 19. As the sampling test tubes are continuously conveyed, the detection placement disk 2 can rotate continuously, so that a plurality of sampling test tubes are sequentially clamped into a plurality of clamping grooves 4. The sampling and placement of the coating are carried out continuously, the loss time in the middle is reduced, and the detection efficiency of the heavy metals inside the coating is improved.

[0029] Embodiment 2

[0030] On the basis of Embodiment 1, in order to enable the detection placement disk 2 to rotate stably when the conveyor belt 12 conveys a plurality of sampling test tubes, as Figures 2-3 shown, a transmission rod 14 is rotatably provided at the bottom of the upper end inside the spectrometer 1. The end of the driving roller 10 passes through the annular plate 9 and is fixedly provided with a first bevel gear 15. The top of the transmission rod 14 is fixedly provided with a second bevel gear 16. The first bevel gear 15 and the second bevel gear 16 are arranged in cooperation. Synchronous wheels 17 are fixedly sleeved on the rod walls of the transmission rod 14 and the vertical rod 3, and a synchronous belt 18 is sleeved on the two synchronous wheels 17 in a common transmission manner.

[0031] When the driving roller 10 rotates, the first bevel gear 15 rotates accordingly. Through the meshing of the first bevel gear 15 and the second bevel gear 16, the transmission rod 14 starts to rotate synchronously. At this time, under the transmission cooperation of the two synchronous wheels 17 and the synchronous belt 18, the vertical rod 3 can drive the detection placement disk 2 to rotate stably, so that a plurality of sampling test tubes can be stably clamped into each clamping groove 4 during continuous conveying, ensuring that the sampling test tubes can be quickly and conveniently installed and reducing manual intervention.

[0032] Embodiment 3

[0033] On the basis of Embodiment 1, in order to ensure the stable feeding of the coating sample, as Figure 1 shown, a feeding port is opened at the top of the barrel 6. A sealing plug 22 is arranged inside the feeding port. A driving motor 20 is fixedly provided at the top of the barrel 6. The output end of the driving motor 20 passes through the barrel 6 and is fixedly provided with a stirrer 21.

[0034] By setting the feed port, the paint can stably enter the barrel 6 for sampling. At the same time, when the paint is discharged, the drive motor 20 can drive the agitator 21 to rotate, so as to avoid the precipitation of the paint in the barrel 6 as much as possible, thereby ensuring accurate detection of heavy metals inside the paint.

[0035] Example 4

[0036] Example 4 is based on Example 1 to ensure that the detection process is not affected by external factors. Figure 1 As shown, the cover shell 5 is a transparent cover shell, and a connecting hole is opened on the side wall. A cover plate 24 is provided on the outer side of the connecting hole, and the cover plate 24 is screwed and fixed to the cover shell 5 by bolts 25.

[0037] After the cover plate 24 is connected to the housing 5, the spectrometer 1 and the housing 5 are integrated to ensure that the internal detection work is not affected. At the same time, the transparent setting of the housing 5 allows for intuitive observation of the transportation and placement of the sampling tubes, which is convenient for timely adjustment.
