Description

Technical Field

[0001] The present invention belongs to the technical field of coil testing instruments, and more specifically, relates to a coil baking test device. Background Art

[0002] In the past, when testing the baking of waterproof coils, first, an operator needed to hold a blowtorch by hand and move it back and forth at a certain distance above the waterproof coil for heating. Then, after the surface of the waterproof coil presented a molten state, the blowtorch was removed. Finally, an apparent evaluation was carried out on the surface of the baked coil.

[0003] In the past, when testing the hot melt bonding of waterproof coils, first, an operator needed to hold a flame blowtorch by hand and heat the waterproof coil back and forth. Then, after the coil presented a molten state, the coil was rolled and laid on a concrete base layer, and at the same time, a certain pressure was applied to the other side of the coil to expel the air between the coil and the base layer and ensure firm bonding between the coil and the base layer. After the temperature of the waterproof coil dropped to the required temperature, a bonding performance test was carried out on it.

[0004] The existing coil baking tests have the following disadvantages: (1) It is difficult to keep the distance between the hand-held blowtorch head and the coil constant; (2) The residence time of the flame on the surface of the coil is manually controlled, with a large error; (3) The moving speed of the flame on the surface of the coil is manually controlled and it is difficult to maintain a constant speed; (4) The size of the flame is manually controlled and it is difficult to be constant; (5) During the hot melt bonding process of the coil, it is difficult to keep a constant and uniform speed when the coil is rolled. Therefore, the subjective factors of the operator in the existing coil baking tests will cause different baking states of the coil, making it difficult to ensure fairness and accuracy in the coil performance test.

Every time the torch 22 moves from one end of the transverse slide rail 13 to the other end, the tray 5 slides forward a set distance, so that the surface of the coil specimen 41 is evenly baked by the flame, and then the surface of the baked coil specimen 41 can be visually evaluated.

[0169] When conducting the hot-melt paving test of the coil material, place the base specimen flat in the tray 5. The base specimen can be a coil material or a cement board. Wind the coil specimen 41 around the outside of the coil roller 25, and place the end of the coil specimen 41 at the end of the base specimen and press it fixed by the pressing roller 29. Adjust the distance between the torch 22 and the surface of the coil specimen 41 by adjusting the installation position of the installation rod 23 in the torch installation position 21, and adjust the flame spraying angle of the torch 22 by rotating the torch installation beam 20, and then adjust the flame size of the torch 22. Set the rotation mode and speed of the first drive motor 7 and the second drive motor 14 in the control unit, so as to control the moving speed of the tray 5 on the longitudinal slide rail 6 and the reciprocating moving speed of the torch 22 on the transverse slide rail 13. Light the torch 22, start the test device, the torch 22 moves back and forth horizontally to bake the coil specimen 41, and at the same time the tray 5 moves forward intermittently at the set speed; every time the torch 22 moves from one end of the transverse slide rail 13 to the other end, the tray 5 slides forward by a set distance, so that the surface of the coil specimen 41 is evenly baked by the flame; the movement of the tray 5 drives the pressing roller 29 to rotate, and presses the baked coil specimen 41 on the surface of the base specimen, so as to hot-melt paste the coil specimen 41 on the base specimen in the tray 5. After cooling, the bonding strength test of the coil specimen 41 can be carried out.

The installation position of the torch 22 is adjusted by adjusting the installation position of the torch slider 40 on the torch sliding rod 39. The firing angle of the torch 22 is adjusted by rotating the angle between the torch 22 and the installation rod 23, and then the flame size of the torch 22 is adjusted.
