During manufacturing, the heat insulation sleeve B is firstly sleeved on the support rod, the pipe A moves through the assembly hole 23 on the assembly frame, the heat insulation sleeve B is expanded through the support rod and then enters the heat insulation sleeve B, and the surface of the heat insulation sleeve B which passes through the electric heating cylinder is uniformly heated to shrink the heat shrinkage pipe through the first guide frame and the second guide frame by the pipe A sleeved with the heat insulation sleeve B. Because the heat-insulating sleeve B adopts the heat-insulating layer and the surface of the heat-insulating layer is covered with the heat-shrinkable layer, when the pipe sleeved with the heat-insulating sleeve passes through the heating area reaching the temperature of the heat-shrinkable layer, the heat-shrinkable layer shrinks to ensure that the heat-insulating sleeve can be fixed with the surface of the pipe, thereby avoiding the production difficulty when the inner hole of the heat-insulating sleeve is too small, having poor heat-insulating effect when the inner hole of the heat-insulating sleeve is too large, and improving the heat-insulating effect without.

When the surface of the insulating sleeve is heated, the distance between the insulating sleeve and the heating mechanism is the same, so that the insulating sleeve can be uniformly heated and shrunk, and the surface of the formed insulating pipe is smooth and attractive.

During manufacturing, the heat-insulating sleeve is firstly sleeved on the pipe, and the pipe sleeved with the heat-insulating sleeve is heated, so that the surface of the heat-insulating sleeve is uniformly heated, and the heat-shrinkable layer is uniformly shrunk. Because the heat-insulating sleeve adopts the heat-insulating layer and the surface of the heat-insulating layer is covered with the heat-shrinkable layer, when the pipe sleeved with the heat-insulating sleeve passes through the heating area reaching the temperature of the heat-shrinkable layer, the heat-shrinkable layer shrinks to ensure that the heat-insulating sleeve can be fixed with the surface of the pipe, thereby avoiding the production difficulty when the inner hole of the heat-insulating sleeve is too small, having poor heat-insulating effect when the inner hole of the heat-insulating sleeve is too large, and improving the heat-insulating effect without.
