Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] The following will further elaborate on this application Figures 1 - 3 in more detail.

[0025] Referring to Figure 1 , a plastic foam strength detection device includes a bottom plate 1. A positioning seat 2 and a movable seat 3 are arranged on the bottom plate 1. A hydraulic telescopic rod 4 for pushing the movable seat 3 is also arranged on the bottom plate 1. Bonding plates 5 are arranged on both the positioning seat 2 and the movable seat 3. Glue is evenly applied on the bonding plates 5 to bond the plastic foam above, so as to detect the strength of the plastic foam. A tension sensor 11 is arranged on the bottom plate 1 and between the movable seat 3 and the positioning seat 2. The tension sensor 11 is used to detect the received tension, so as to read and record the tension. One side of the tension sensor 11 is fixedly connected to a spring 12, and one end of the spring 12 is fixedly connected to the side of the movable seat 3 away from the hydraulic telescopic rod 4.

[0026] Further, stabilizing frames 8 are arranged on one side of both the positioning seat 2 and the movable seat 3. An electric telescopic rod 9 is fixedly connected to one side of the stabilizing frame 8. The electric telescopic rod 9 is used to push the stabilizing pressing plate 10, so as to better position plastic foams with different thicknesses, and thus facilitate subsequent strength detection. The bottom end of the electric telescopic rod 9 is fixedly connected to the stabilizing pressing plate 10.

[0027] Further, referring to Figure 3 , a convex tooth 14 is also fixedly connected to the bottom of the stabilizing pressing plate 10, which is used to be clamped to the top of the plastic foam during extrusion, so as to better position the plastic foam and facilitate subsequent detection.

[0028] Further, referring to Figure 2 , a convex block 6 is fixedly connected to the bottom of the bonding plate 5. Grooves 7 are formed on both the positioning seat 2 and the movable seat 3. The convex block 6 can be clamped inside the groove 7.

[0029] Further, a sliding groove 13 for the sliding of the movable seat 3 is also formed on the bottom plate 1, making the sliding of the movable seat 3 more stable.

[0030] The implementation principle of this embodiment is as follows: When in use, glue is evenly applied to the two sets of bonding plates 5, and then both sides of the plastic foam are bonded respectively. Then, the electric telescopic rod 9 is started to make the telescopic end of the electric telescopic rod 9 extend, and the plastic foam is locked and positioned by the stable pressing plate 10. Then, the hydraulic telescopic rod 4 is used to pull the movable seat, and at the same time, the pulling force gradually increases. During the process of the plastic foam deforming to rupture, the pulling force data can be real-time monitored by the pulling force sensor 11, so that the strength of the plastic foam can be calculated. Then, the bonding plate 5 can be removed from the movable seat 3 and the positioning seat 2 for replacement to improve the detection effect.
