Protection device for hot-melt pipe

[0022] Example

[0023] Such as figure 1 , 2 As shown, a protection device for a hot melt tube of the present invention includes a shell 1 and a shell cap 2. The number of shell caps 2 is two, which are respectively connected to both ends of the shell 1 by threads, and belong to the shell cap 2. Both ends of the housing 1 are provided with openings, the upper surface of the housing 1 is provided with an air inlet 3, the lower surface of the housing 1 is provided with an air outlet 4, and the housing 1 is provided with a temperature sensor 5 and a temperature display The temperature sensor 5 is arranged on the inside of the housing 1, the temperature display 6 is arranged on the outside of the housing 1, and the output terminal of the temperature sensor 5 is connected to the output terminal of the temperature display 6. The housing 1 also includes The upper half shell 7 and the lower half shell 8 are connected by screws between the upper half shell 7 and the lower half shell 8. The shell cap 2 includes an upper half shell cap 9 and a lower half shell cap 10, so The upper half shell cap 9 and the lower half shell cap 10 are connected by screws. The shell 1 includes an insulation layer and a waterproof layer. The waterproof layer is arranged on the outside of the shell 1, and the insulation layer is arranged on the inside of the shell. Both the air inlet 3 and the air outlet 4 are provided with a plug 11, and the diameter of the plug 11 is equal to the diameter of the air inlet 3 and the air outlet 4.

[0024] This shell fixes the shell 1 and the shell cap 2 outside the hot melt pipe through screw connection, and fixes the shell cap 2 on the shell 1 through the screw connection. The high temperature gas is input from the air inlet 3, and the air outlet 4 is opened to discharge the previous The air heats the heat shrinkable tube, and the temperature sensor inside the housing 1 senses the internal temperature, which is transmitted to the display on the outside of the housing 1 for display. When it displays 98°C, plug the air inlet 3 with a plug 13 And the air outlet 4, heat the hot melt tube, so as to solve the problem that the traditional direct heating method will damage the hot melt tube, and will cause uneven heating and incomplete shrinkage of the heat shrink tube.
