Guide pipe preheating device and preheating system

The guiding pipe preheating device comprises a guiding pipe and a preheating assembly arranged on the guiding pipe in a wrapping mode, the preheating assembly comprises a preheating piece used for heating the guiding pipe, a heating wire arranged on the preheating piece and an elastic piece, the two ends of the elastic piece are connected with the preheating piece in a head-to-tail mode, and the guiding pipe is wrapped with the preheating piece. And the heat of the preheating piece is continuously transferred to the guide pipe. The two ends of the elastic piece are connected with the preheating piece in an end-to-end mode, the preheating piece wraps the guide pipe, heat of the preheating piece is continuously transmitted to the guide pipe, preheating time is short, attachment of high-temperature raw materials and the guide pipe in the prior art is omitted, and therefore a large number of raw materials are saved, and production cost is reduced. And meanwhile, the situation that multiple persons operate the gui
