TECHNICAL FIELD

[0002] Aramid honeycomb is a biomimetic honeycomb core material made of aramid fiber paper, has excellent compression strength and lightweight characteristics, and is widely used in the fields of aerospace, automobiles, ships and the like. After aramid honeycomb production is completed, the compression strength thereof needs to be detected through compression testing to ensure that the product meets the use requirements.

[0003] A compression strength testing machine is disclosed in a patent with the authorized announcement number CN111579373B, which comprises a machine body, a first fixed shaft fixedly arranged on the machine body, a second fixed shaft fixedly arranged on the machine body, an upper pressing seat movably sleeved on the first fixed shaft and the second fixed shaft, a driving device for driving the upper pressing seat to move up and down, a lower pressing seat arranged directly below the upper pressing seat, and a hydraulic pump for driving the lower pressing seat to move up and down. The application can shorten the detection time, improve the detection efficiency, automatically align the test piece and uniformly bear the force, and accurately measure the data. However, the testing machine cannot be connected with the production line, workers need to carry the aramid honeycomb to the testing machine, and then manually detect the aramid honeycomb one by one, which is labor-intensive and low in detection efficiency.

[0004] A corrugated board strength detection machine is disclosed in a patent with the authorized announcement number CN221612558U, which comprises a conveying roller and a detection mechanism. The detection mechanism comprises a detector arranged in sequence along the conveying direction of the conveying roller, a pressing device capable of sliding vertically relative to the conveying roller, and a conveying device capable of pushing the product with insufficient strength away from the conveying roller. The detector is arranged parallel to the conveying roller and can record the height of the product away from the surface of the conveying roller. The detector can slide along the direction vertical to the conveying roller. The pressing device comprises a main body shell, a sliding rod one and a pressing plate. The sliding rod one slides in the main body shell and can slide out of the main body shell towards the conveying roller. The pressing plate is fixedly connected to one end of the sliding rod one close to the conveying roller. When the paperboard is conveyed into the detection mechanism, the pressing plate exerts force on the paperboard, and the paperboard deforms. The detector measures and judges whether the deformation meets the standard. The problem that unqualified paperboard cannot be found in time during production is solved. The detection machine can be connected with the production line, automatically detect the compression strength of the product, and automatically sort qualified products and unqualified products, thereby reducing the labor intensity of workers and improving the detection efficiency. However, in the technical solution, the product to be detected is directly placed on the conveying roller for detection, the product is not stressed uniformly, and the accuracy of the detection result is not high.

[0064] In one specific technical solution, the left and right side walls of the box body 31 are respectively provided with a second sliding hole 312 for the second guide plate 32 to pass through and a third sliding hole 313 for the locking rod 36 to slide through, and the bottom is provided with a fourth sliding hole 314 for the pressing rod 37 to pass through, the horizontal plate 35 is provided with two, respectively close to the front and rear side walls of the box body 31, and the two second guide plates 32 can form a "Y" type channel.

[0065] In the above technical solution, the second sliding hole 312 is an inclined hole matched with the second guide plate 32, and the locking rod 36 is arranged in the third sliding hole 313, which can improve the lifting stability of the locking rod 36 and improve the locking effect. It should be noted that the locking rod 36 in the present application can also be directly arranged outside the left and right side walls of the box body 31 and can be lifted to abut and lock the second guide plate 32, and the pressing rod 37 can also be directly arranged at the through hole 311 of the box body 31 and can pass through the bottom of the box body 31.

[0066] In one specific technical solution, the second guide plate 32 comprises an inclined section 321 and a vertical section 322, the inclined section 321 is slidably penetrated through the side wall of the box body 31, the inner side wall of the box body 31 is provided with an embedded groove 315 for accommodating the vertical section 322, the upper end surface of the inclined section 321 is provided with a plurality of positioning holes 3211 for inserting the positioning blocks 33 at equal intervals in the length direction, and the lower end surface is provided with a locking groove 3212 for inserting the locking rod 36.

[0067] In the above technical solution, one second guide plate 32 can be provided with one inclined section 321, or two parallel inclined sections 321, which are arranged at the upper and lower ends of the vertical section 322. In this embodiment, one second guide plate 32 is provided with one inclined section 321. Since it has a guiding function, when there is only one inclined section 321, the inclined section 321 must be arranged at the upper end of the vertical section 322, which is a common knowledge and will not be repeated. The inclined section 321 is slidably penetrated through the side wall of the box body 31, i.e. the inclined section 321 is slidably penetrated through the second sliding hole 312. When there are two inclined sections 321, two second sliding holes 312 are arranged on one side wall correspondingly. The lower end surface of the vertical section 322 is preferably a circular arc surface. The inclined sections 321 of the two second guide plates 32 can form a guiding inclined surface, and the vertical section 322 can form a falling channel. A plurality of positioning holes 3211 are arranged on the inclined section 321, which can flexibly adjust the distance between the two second guide plates 32 to adapt to different models and sizes of aramid honeycomb. The lower end surface of the inclined section 321 is provided with a locking groove 3212 matched with the locking rod 36. When the vertical section 322 is completely inserted into the embedded groove 315, the locking groove 3212 is just moved to the position of the locking rod 36, and forms a plug-in state with the locking rod 36, which can further improve the locking effect of the locking rod 36 on the second guide plate 32.
