[0028] The intermittent lifting assembly includes a guide rail 4 fixedly arranged in the inspection box 1 and a slide groove 5 opened in the inspection box 1. There are two guide rails 4, and moving blocks 6 are slidably arranged on the two guide rails 4. A connecting plate 7 is fixedly arranged between the two moving blocks 6, and the placement plate 2 is fixedly arranged on the connecting plate 7. A fixed block 8 is fixedly arranged on the connecting plate 7, and a tooth plate 9 is fixedly arranged on the fixed block 8. A slider 10 is fixedly arranged on the tooth plate 9, and the slider 10 is slidably arranged in the slide groove 5. A gear 11 and a drive disk 12 are sequentially arranged on one side of the tooth plate 9, and the gear 11 is meshed with the tooth plate 9. A plurality of mating teeth 120 are sequentially fixedly arranged on the drive disk 12, and the plurality of mating teeth 120 and the gear 11 are mated with each other. A driven disk 13 is fixedly provided on the gear 11, a driving disk 14 is fixedly provided on the driving disk 12, a matching arc groove 15 is provided on the driven disk 13, the driving disk 14 is attached to the matching arc groove 15 on the driven disk 13, a matching groove 140 is provided on the driving disk 14, a servo motor 16 is docked on the driving disk 14, and the servo motor 16 is fixedly provided on the inspection box 1.
[0029] When the present invention is used, firstly, the PVC material is placed on the placement plate 2, and then the flamethrower 21 is started to burn the PVC material on the placement plate 2, and the changes of the PVC material during the burning process are observed. When different temperatures are required to burn the PVC material, the servo motor 16 is started, and the start of the servo motor 16 drives the active disk 14 connected thereto to rotate, and the rotation of the active disk 14 drives the driving disk 12 to rotate. When the matching teeth 120 on the driving disk 12 rotate to the gear 11, the driving disk 12 drives the gear 11 to rotate through the matching teeth 120, and the rotation of the gear 11 The tooth plate 9 is driven to move in the vertical direction, and the movement of the tooth plate 9 drives the placement plate 2 to move through the fixed block 8. The movement of the placement plate 2 drives the PVC material on the placement plate 2 to move upward. Each rise of the PVC material will be closer to the outer flame of the flame sprayed by the heat resistance test component.
