[0033] Working principle: When in use, first place the injection molded part to be detected on the workbench 1. Then start the second motor 20. The second motor 20 drives the two pressing plates 18 threadedly connected to it to move through the bidirectional threaded rod 21. At the same time, since the thread directions of the bidirectional threaded rod 21 are opposite, at this time the two pressing plates 18 approach each other until the soft pad 26 abuts tightly against the injection molded part. Then start the hydraulic cylinder 16. The hydraulic cylinder 16 drives the detection device 17 to move downward to abut against the injection molded part to perform a hardness test on it. When the injection molded part is stressed too much, its surface will be damaged, resulting in debris scattered on the workbench 1. At this time, it can be cleaned. Just start the first motor 10. The first motor 10 drives the connected threaded short rod 6 to rotate. The threaded short rod 6 drives the double-row pulley 11 to rotate. The double-row pulley 11 drives the two single-row pulleys 12 to rotate through the two synchronous belts 13. At this time, the three threaded short rods 6 rotate synchronously. The threaded short rod 6 drives the moving plate 7 threadedly connected to it to move. The moving plate 7 pushes the push plate 9 to move through the connecting rod 8, so as to be able to push the debris on the workbench 1 to move and fall into the collection box 2 through the first material dropping port 3 and the second material dropping port 4, which is convenient for subsequent centralized processing.
