[0038] It should be noted that the pipe sleeve 112 penetrating through the two side walls 114 of the box body assembly plays a limiting role.

The present embodiment uses a heating coil device in conjunction with an electromagnetic controller. By controlling a high-frequency, high-voltage current with a frequency of 11-20KHZ, a high-speed changing alternating magnetic field will flow through the heating coil, thereby ensuring that the hot melt adhesive 1 remains in a liquid state. At the same time, the electromagnetic controller is linked to the host, and the frequency is adjusted according to the production speed to control the heating rate of the heater 230 to avoid excessive heating of the hot melt adhesive 1 and damage to the tube sleeve 112.

[0054] Preferably, the tube sleeve 112 is made of stainless steel.

[0055] In this embodiment, the sleeve 112 is preferably made of stainless steel. Due to the special property of low thermal conductivity, the stainless steel can effectively protect the loose tube 3 from being damaged when passing through the box structure 110.
