[0030] The receiving plate 3, the pulling assembly 4, the sliding rod 8 and the compression spring 9 are slidably arranged in the detection box 1. During the pulling of the box door 2, the support rod 7 is pulled as a whole, and the sliding block 6 is slid as a whole during the pulling of the support rod 7.

[0034] Working principle:

[0035] When the heat resistance of the plastic particles needs to be detected, the box door 2 is pulled. The box door 2 pulls the whole support rod 7 during the pulling process. The whole support rod 7 pulls the whole sliding block 6 during the pulling process. The whole sliding block 6 pulls the whole receiving plate 3 when the sliding block 6 is pulled to one end. The whole receiving plate 3 pulls the whole protruding block 31 during the outward movement of the receiving plate 3. The whole protruding block 31 compresses the compression spring 9 during the movement of the protruding block 31. The plastic particles are poured into the receiving box 10. The fixed lug 101 is clamped and installed in the clamping groove 32. The receiving box 10 is rotated in the positive direction. The whole receiving box 10 is rotated during the rotation of the receiving box 10. Thus, the whole installation process of the receiving box 10 is completed.

[0036] During detection, the box door 2 is covered on the detection box 1. The plastic particles received on the receiving box 10 are assisted by the heating wire in the detection box 1. During the heating process, the servo motor 131 is started. The servo motor 131 drives the whole air guide wheel 13 to rotate. Thus, the airflow in the detection box 1 enters the mounting seat 15 through the duct 14. The airflow enters the filter cartridge 16 through the pipeline. The exhaust gas is assisted by the processing liquid in the filter cartridge 16. When the filter cartridge 16 needs to be disassembled, the filter cartridge 16 is turned over. The clamping lug 161 is withdrawn from the clamping groove 152 to the plug-in groove 151. Thus, the disassembly of the filter cartridge 16 is completed. The liquid in the filter cartridge 16 can be replaced.
