[0046] During specific use, first place the cork board to be tested on the reference board one 41 and the reference board two 42. Start the electric suction cup 44 to adsorb on the lower end of the cork board to fix the cork board. Use the marking pencil 10 to draw the outline on the reference board one 41 and the reference board two 42 along the cork board. The output end of the lifting cylinder 34 moves to drive the lifting plate 39 to move downward. The downward movement of the lifting plate 39 drives the cylindrical roller 37 to move downward until the arc block 38 presses on the cork board. The output end of the motor 26 rotates to drive the lead screw 27 to rotate. The rotation of the lead screw 27 drives the sleeve one 28 and the sleeve two 29 to move. The movement of the sleeve one 28 and the sleeve two 29 drives the connection frame 25 to move, thereby driving the cork board to move. Use the arc block 38 to apply pressure on the cork board and record the size and shape of the indentation on the cork board. The output end of the lifting cylinder 34 moves upward until the arc block 38 leaves the cork board. Start the hot air blower 48. The hot air flow is conveyed through the output pipe 49 into the fixed pipe 36 and then enters the cylindrical roller 37 through the air outlet one 50 and finally sprays out from the air outlet two 51. The output end of the motor 26 rotates to drive the cork board to move back and forth at the lower end of the cylindrical roller 37 to increase the temperature of the cork floor, thereby promoting the expansion and recovery of the cork floor, and thus detecting the indentation recovery effect of the cork board. The function of the spring 47 is to buffer the deformation generated when the cylindrical roller 37 presses on the cork board. Start the heating component 17 and the cooling pipe 19. Start the reciprocating drive component 15. Move the plugging type heat switching component 14 to the heating chamber 16. Close the lifting opening and closing door 7 to heat the cork board. At this time, the square sealing block one 23 blocks the square plugging opening 20. After a period of time, start the reciprocating drive component 15 to move the cork board to the cooling chamber 18 to cool the cork board. At this time, the square sealing block two 24 blocks the square plugging opening 20. Within a certain temperature range, perform cyclic heating and cooling on the cork floor, observe whether the size and shape of the cork floor change, and judge the thermal stability of the cork floor. The better the thermal stability, the less likely the cork floor is affected by temperature changes and the more suitable it is for different climate conditions; observe whether cracks occur on the cork floor to judge the thermal cracks of the cork floor. The fewer the thermal cracks, the more resistant the cork floor is to the impact of temperature changes and the less likely it is to be damaged. Repeat the indentation detection of the cork board before to observe whether the performance of the cork floor degrades and judge the thermal fatigue of the cork floor. The smaller the thermal fatigue, the more capable the cork floor is of withstanding the cycle of temperature changes and the less likely it is to lose elasticity or strength. The above is the overall working process of the present invention. Just repeat this step the next time it is used.
