[0019] See also Figure 1~Figure 2 , the embodiments of the present utility model include:

[0020] like Figure 1 The plastic particle strength efficient detection device shown includes: a base 1, a support column 11, a top plate 4, a lifting plate 3, a pressure plate 6, a tension pressure sensor 7, a height adjustment block 13, a fixed plate 2 and a carrier 9. The support columns 11 are symmetrically arranged on the base 1, and the top plate 4 is arranged on the top of the support columns 11. There are two support columns 11 on the left and right, which provide good support for the top plate 4.

[0021] The lifting platform 3 is disposed below the top plate 4 in a manner such that it can be raised and lowered. In this embodiment, the top plate 4 is provided with a lifting drive mechanism 5 connected to the lifting platform 3. The lifting drive mechanism 5 can be a hydraulic cylinder and is controlled by a PLC controller. The lifting platform 3 is provided with a guide sleeve 17 corresponding to the support column 11. The support column 11 and the guide sleeve 17 cooperate to guide the lifting of the lifting platform 3, providing high stability.

[0022] A tension and pressure sensor 7 is mounted on the bottom of the lifting plate 3 and secured with bolts. A pressure plate 6 is positioned below the tension and pressure sensor 7 and moves upward and downward along with the tension and pressure sensor 7 and the lifting plate 3. The tension and pressure sensor 7 can be connected to a PLC controller, with the touchscreen on the PLC controller displaying real-time pressure.

[0023] Guide posts 8 are symmetrically arranged on the pressing plate 6 and penetrate the lifting plate 3 upward. Guide holes corresponding to the guide posts 8 are provided in the lifting plate 3 to guide the pressing plate 6, avoid tilting of the pressing plate 6, and ensure that the pressing plate 6 can apply uniform pressure to each plastic particle 16 below.

[0024] The fixing plate 2 is set on the support column 11 and is located below the pressing plate 6, as shown in FIG. Figure 1 As shown, the support column 11 is provided with a nut 10 located below the fixing plate 2 to limit the height of the fixing plate 2. The support column 11 is provided with an external thread corresponding to the nut 10 to facilitate the adjustment of the nut 10 so that the fixing plate 2 remains horizontal.

[0025] The carrier 9 is placed horizontally on the fixing plate 2 and can be fixed with bolts. The top of the carrier 9 is concavely provided with multiple plastic particle positioning grooves 18. Multiple columnar plastic particles 16 can be placed in corresponding plastic particle positioning grooves 18. The bottoms of the plastic particles 16 are positioned one by one through the plastic particle positioning grooves 18, and strength testing is performed simultaneously, thereby improving testing efficiency.

The height adjustment block 13 is provided in the plastic particle positioning groove 18 and is located above the screw 15. In this embodiment, a threaded hole 12 corresponding to the screw 15 is provided at the bottom of the plastic particle positioning groove 18. The axial adjustment can be performed by rotating the screw 15 to change the position height of the height adjustment block 13, thereby adjusting the top surface position height of the plastic particle 16 above the height adjustment block 13, so that the top surface position height of all plastic particles 16 is uniform.

The avoidance groove 14 is large to avoid the rotation operation of the screw 15 by a screwdriver. Figure 2 As shown, the pressing plate 6 is first lowered to the top of the highest plastic particle by the lifting plate 3, and then the remaining height adjustment blocks 13 are adjusted by rotating the screw 15 to ensure that the top of each plastic particle is in contact with the bottom surface of the pressing plate 6. Finally, the pressing plate 6 is continued to be pressed down, and the deformation of the plastic particles is observed. The tension pressure sensor 7 is used to monitor the pressure in real time to realize the strength detection of the plastic particles.
