Here, the limiting plate 262 is rotated so that the limiting plate 262 supports the bottom of the supporting plate 254, so that the test piece can be placed horizontally.

[0034] The working principle of this belt flame retardancy test device: When in use, rotate the limiting plate 262 to support the bottom of the supporting plate 254, and then place the test piece into the limiting groove 2541. At this time, rotate the threaded column 252 so that its end squeezes and fixes the test piece. In this way, multiple test pieces can be installed at the same time. Then, use two servo motors 211 to rotate simultaneously, and drive the threaded rod 212 to rotate under the action of the transmission part 214. In this way, the movable block 213 drives the annular frame 220 to move to one side, so that one of the test pieces is located above the combustion head 144. Then, use the electric cylinder 141 to adjust the distance between the flame of the combustion head 144 and the test piece. After the combustion is completed, the servo motor 211 drives the threaded rod 212 to rotate again, so that the other test piece is located above the combustion head 144. At this time, rotate the limiting plate 262 to make it away from the bottom of the supporting plate 254, and then rotate the rotating rod 241 and the rotating disc 242 through the knob 243, and flip the test piece through the rotating disc 242. In this way, external testers can observe and record the burning part of the test piece. At the same time, another test piece can continue to be subjected to the combustion test. In this way, the continuity of the test sample detection can be improved during the test, the test efficiency can be improved, and at the same time, it is convenient to observe and record the spread of the combustion part, and the use is more intuitive and convenient.

[0035] It should be noted that the specific model and specifications of the servo motor 211 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail here.

[0036] The power supply and principle of the servo motor 211 are clear to those skilled in the art, and will not be described in detail here.
