[0025] Example

[0026] Please see Figures 1 to 6 A material combustion performance testing device includes a testing machine 1, which includes a housing 2 with a hinged door and a transparent viewing panel in the middle of the door. A burner 3 is movably disposed inside the housing 2 and is inclinedly disposed on a mounting plate 6. A mounting rod 5 is longitudinally movable inside the housing 2 via a lifting mechanism 4. An abutment ring 30 is fitted on the mounting rod 5 and is coaxially fixedly connected to the abutment ring 30. The device also includes a mounting plate 6, a clamping mechanism, and a collecting mechanism.

[0027] It should be added that the testing machine 1 is equipped with a display screen 26 for controlling the start and stop of the burner 3, and is also equipped with a timer to monitor the combustion time;

[0028] The mounting plate 6 can be moved and installed inside the housing 2 via a moving mechanism. The burner 3 is installed on the mounting plate 6 and is used to move the burner 3 in conjunction with the moving mechanism. The moving mechanism includes a first support rod 7, a moving frame 9, a second support rod 10, and a drive assembly. Two first support rods 7 are symmetrically arranged inside the housing 2. Both ends of the first support rod 7 are fixedly connected to support plates 8. Both first support rods 7 pass through the moving frame 9 and slide in cooperation with the moving frame 9. Two second support rods 10 are symmetrically arranged inside the moving frame 9. Both second support rods 10 pass through the mounting plate 6 and slide in cooperation with the mounting plate 6.

[0029] The drive assembly is mounted on the movable frame 9 and the mounting plate 6, respectively, to drive the mounting plate 6 and the movable frame 9 to move. The drive assembly includes a drive shaft 11, a gear 12, and a rack 13. One end of the drive shaft 11 passes through the housing 2 and is rotatably mounted inside the movable frame 9. A snap-fit ​​groove 24 is provided inside the movable frame 9, and a limit ring 25 is rotatably mounted inside the snap-fit ​​groove 24. The limit ring 25 is fitted onto the drive shaft 11 and is coaxially fixedly connected to the drive shaft 11, so that the drive shaft 11 and the movable frame 9 are kept in a "connected" state. By pulling the drive shaft 11, under the limiting action of the limit ring 25, the drive shaft 11 drives the movable frame 9 to move under the guidance of the two first support rods 7. The support moves to drive the mounting plate 6 and the burner 3. The gear 12 is fitted onto one end of the drive shaft 11 and is coaxially and fixedly connected to the drive shaft 11. The moving frame 9 has a sliding groove. The rack 13 is slidably disposed in the sliding groove and fixedly connected to the mounting plate 6. The rack 13 and the gear 12 mesh. By rotating the drive shaft 11, the drive shaft 11 drives the gear 12 to rotate. The rotation of the gear 12 drives the rack 13 to move along the sliding groove. The rack 13 drives the mounting plate 6 and the burner 3 to move. The directions of pulling the drive shaft 11 and rotating the drive shaft 11 to drive the mounting plate 6 to move are perpendicular to each other, so that the mounting plate 6 can move in two directions on the horizontal plane.

[0030] The clamping mechanism is detachably mounted on the mounting rod 5 for clamping and fixing the material to be tested. The clamping mechanism includes a first clamping plate 14, a second clamping plate 16, an abutment plate 18, and a locking bolt 19. The first clamping plate 14 is movably mounted on the lower side of the mounting rod 5 via a first connecting plate 15, and the second clamping plate 16 is movably mounted on the lower side of the mounting rod 5 via a second connecting plate 17. Both the first connecting plate 15 and the second connecting plate 17 have through holes that mate with the mounting rod 5. A protruding plate 27 is fixedly connected to the first connecting plate 15, and a pin 28 is slidably mounted inside the protruding plate 27, penetrating the protruding plate 27. The mounting rod 5 has a insertion hole 29 that mates with one end of the pin 28. The first clamping plate 14 and the second clamping plate 16 are detachably mounted on the mounting rod 5. All holding plates 16 are U-shaped. One end of the abutment plate 18 is fixedly connected to one end of the first clamping plate 14. The abutment plate 18 is slidably engaged with one end of the second clamping plate 16. The first connecting plate 15 and the second connecting plate 17 are threadedly engaged with the locking bolt 19. The cut material (generally square) is placed between the first clamping plate 14 and the second clamping plate 16. The first connecting plate 15 and the second connecting plate 17 are locked and fixed by using the locking bolt 19. Then, the first connecting plate 15 and the second connecting plate 17 pass through the mounting rod 5 and the second connecting plate 17 abuts against the abutment ring 30. Then, the pin 28 is inserted into the insertion hole 29. In this way, the material is vertically fixed on the lower side of the mounting rod 5 and at an angle above the burner 3.

[0031] It should be added that the material is cut to size according to the size of the first clamping plate 14 and the second clamping plate 16. Therefore, the first clamping plate 14 and the second clamping plate 16 are both matched with the cut square material. The distance between the first clamping plate 14 and the second clamping plate 16 after the material is fixed is fixed. Therefore, when the second connecting plate 17 abuts against the abutting ring 30, the pin 28 can be inserted into the insertion hole 29. By providing the abutting plate 18, the material can be "supported".

[0032] The collection mechanism is detachably installed below the clamping mechanism to collect fallen debris. The collection mechanism includes a fixed plate 20, a collection frame 21, and mesh 23. The fixed plate 20 is fixedly connected to the other end of the abutment plate 18. Both fixed plates 20 and the collection frame 21 are threadedly engaged with fixing bolts 22. The collection frame 21 has a slot that matches the movement trajectory of the burner 3. Multiple mesh holes 23 are provided inside the collection frame 21. The mesh holes 23 have a small aperture and make it difficult for debris to move out of the mesh holes 23, which can play the role of collection and heat dissipation. The cross-sectional area of ​​the collection frame 21 is larger than the cross-sectional area of ​​the cut material. By making both fixed plates 20 abut against the inner side wall of the collection frame 21, and using two fixing bolts 22 to fix the two fixed plates 20 and the collection frame 21, it is easy to disassemble and clean the collection frame 21. When the burner 3 is moved to be on the lower side of the fixed material, the debris produced after the material burns can fall into the collection frame 21.

[0033] Working principle: When testing the burning time of building materials, this material combustion performance testing device cuts the material to be tested into a shape that matches the clamping mechanism. The cut material is placed between the first clamping plate 14 and the second clamping plate 16. The first connecting plate 15 and the second connecting plate 17 are locked and fixed using locking bolts 19. Then, both fixing plates 20 abut against the inner side wall of the collection frame 21. The two fixing plates 20 and the collection frame 21 are fixed using two fixing bolts 22. The first connecting plate 15 and the second connecting plate 17 are driven to pass through the mounting rod 5, and the second connecting plate 17 abuts against the abutment ring 30. Then, the pin 28 is inserted into the insertion hole 29. In this way, the material is vertically fixed to the lower side of the mounting rod 5, and the collection frame 21 is directly below the material.

[0034] By rotating the drive shaft 11, the drive shaft 11 drives the gear 12 to rotate. The rotation of the gear 12 drives the rack 13 to move along the slide groove. The rack 13 drives the mounting plate 6 and the burner 3 to move. The directions of pulling the drive shaft 11 and rotating the drive shaft 11 to move the mounting plate 6 are perpendicular to each other. This allows the mounting plate 6 to move in two directions on the horizontal plane and positions the burner 3 diagonally below the fixed material. The burner 3 is turned on by clicking the display screen 26, and a timer is started to calculate the combustion time, thus measuring the combustion performance of the material.
