Guide rods 13 are movably installed through the interiors of the two fixing blocks 12. The inner ends of the two guide rods 13 are fixedly installed with the same pressing plate 14. A pressing roller 15 is movably installed inside the pressing plate 14. Springs 16 are sleeved on the outer periphery of the guide rods 13 and located between the fixing blocks 12 and the pressing plate 14. The outer ends of the two guide rods 13 are fixedly installed with the same pull rod 17.

[0023] In this embodiment, the clamping plate 4 is installed through the top of the box body 1 in a clamping manner, and the positioning bolt 10 is threaded through the inside of the positioning frame 7. Through the clamping of the clamping plate 4 and the connection of the positioning bolt 10, it is convenient to take, place and fix the heat insulation cotton.

[0024] In this embodiment, the fixing roller 11 is rotatably arranged at the bottom of the box body 1. A limiting groove is opened through the bottom of the box body 1. The extended part at the bottom end of the heat insulation cotton passes through the limiting groove at the bottom of the box body 1. The position of the heat insulation cotton near the bottom end is tightly fixed by the fixing roller 11 and the pressing roller 15.

[0025] In this embodiment, the pressure roller 15 is rotatably arranged inside the pressing plate 14, and the guide rod 13 is slidably arranged through the inside of the fixed block 12. Under the action of the spring 16, the pressure roller 15 automatically slides towards the fixed roller 11 to automatically press the heat insulation cotton.

[0026] In this embodiment, the adjusting mechanism 3 includes an adjusting seat 18. The adjusting seat 18 is installed through the top of the box body 1.

When in use, first place the automotive heat insulation cotton in the box body 1, heat it through the heating lamp 8, and test the heat insulation performance by detecting the temperature after heat insulation through the second temperature sensor 23 on the other side of the heat insulation cotton. When fixing, take out the clamping plate 4 and place the top end of the heat insulation cotton between the fixing plate 6 and the positioning frame 7. By rotating the two positioning bolts 10, the positioning bolts 10 pass through the positioning frame 7 and slide inwards under the action of the thread to press and fix the heat insulation cotton. Then, snap the clamping plate 4 onto the top of the box body 1. At the same time, pull the pull rod 17 to separate the pressure roller 15 from the fixed roller 11, so that the position of the heat insulation cotton near the bottom end is located between the pressure roller 15 and the fixed roller 11. The pressing plate 14 makes the pressure roller 15 automatically slide towards the fixed roller 11 under the action of the spring 16 to press and fix the position of the heat insulation cotton near the bottom end. Close the door panel of the box body 1, heat the inside of the box body 1 by starting the heating lamp 8, detect and control the specified temperature of the heating through the first temperature sensor 9. The heat is transferred to the other side through the heat insulation cotton, and the temperature after heat insulation is detected by the second temperature sensor 23. Since the temperature is different at different distances, rotate the knob 24 to drive the screw rod 19 to drive the slider 20 to slide, so as to change the distance between the second temperature sensor 23 and the heat insulation cotton to adjust the detection at different positions.
