Description

Technical Field

[0001] The utility model relates to the technical field of pipeline heat preservation material foaming machines, in particular to a polyurethane pipeline heat preservation material processing foaming machine. Background Technique

[0002] The polyurethane foam heat preservation steel pipe, also known as pipe-in-pipe, is composed of a fiberglass outer layer, a polyurethane foam heat preservation layer and a steel pipe. The polyurethane heat preservation layer is formed by injecting two materials into the gap between the fiberglass outer layer and the steel pipe through a polyurethane foaming machine. The two materials chemically react to fully fill the gap between the steel pipe and the fiberglass outer layer, becoming a rigid polyurethane foam heat preservation layer, and having a certain bonding strength, so that a firm whole is formed among the fiberglass outer layer, the heat preservation layer and the steel pipe.

[0003] The Chinese utility model patent with the reference authorization publication number CN220614735U discloses a polyurethane pipeline heat preservation material processing foaming machine, which relates to the related technical field of pipeline heat preservation material foaming machines, including a support seat. A limit sliding groove is opened on the support seat, a toothed plate is slidably inserted in the limit sliding groove, a lower clamping plate is installed on the upper side of the tail end of the toothed plate, and a spring plate is installed on the upper side of the lower clamping plate. Through the design, when the motor drives the gear to rotate, the gear drives the adjacent and mutually staggered toothed plates to move after rotation. The toothed plates slide in their respective corresponding limit sliding grooves, so that the three toothed plates drive the corresponding lower clamping plates to perform relative contraction movements, thereby clamping and fixing the storage tank placed on the support seat. When fixing, the lower clamping plate clamps and fixes the bottom side of the storage tank, and the spring plate and the upper clamping plate squeeze and clamp the upper part of the storage tank.
