As shown in FIG. 1, a hot roll forming machine is used for heating and stretching a material such as a polymer sheet or a roll, and gradually cooling the hot roll to form a spiral net when process conditions are satisfied. The hot roller setting machine comprises a pair of hot rollers 1 for heating the spiral net sheet and a heat preservation device 2 capable of preserving heat of the hot rollers 1.

Next, as shown in fig. 1, in this embodiment, the heat-insulating cover 3 includes a first retainer Wen Zhaoti and a second heat-insulating cover 32 that are disposed opposite to each other, and also at least one of the brackets 4 includes a first bracket body 41 and a second bracket body 42, where the first retainer Wen Zhaoti is rotatably disposed on the first bracket body 41, and the first retainer Wen Zhaoti and the first bracket body 41 form a first assembly, and the second heat-insulating cover 32 is rotatably disposed on the second bracket body 42, and the second heat-insulating cover 32 and the second bracket body 42 form a second assembly, where the first assembly and the second assembly are independent from each other and are driven by different driving parts respectively to operate.
Continuing as shown in fig. 1, the first retainer Wen Zhaoti has a first connecting end 311 and a first free end 312, the second heat-insulating cover 32 has a second connecting end 321 and a second free end 322, the first connecting end 311 is rotatably connected to the first bracket body 41, and the second connecting end 321 is rotatably connected to the second bracket body 42. Contact or proximity structures are provided on the first free end 312 and the second free end 322, respectively. When the heat-retaining cover is at the second position, the first heat-retaining cover Wen Zhaoti and the second heat-retaining cover 32 can form a complete covering surface for the second surface portion 12 of the heat roller by the structures at the first free end 312 and the second free end 322, and the first free end and the second free end may be in contact with each other or not in contact with each other, and the contact structures include insertion, embedding, proximity, locking and the like.

Similarly, when the heat-insulating cover 3 is at the second position, the first end surface 101 and the second end surface 102 of the heat roller 1 can be wrapped in the heat-insulating cover 3 to prevent heat loss at the end surfaces of the heat roller. In particular, in the present embodiment, the heat-insulating cover 3 and the bracket 4 which are rotatably arranged can be detached, so that the heat-insulating cover 3 can be conveniently overhauled.

During heating, the heat-insulating cover 3 serves as a heat-insulating layer for the second surface portion 12 of the thermo roll 1, and the heat is reflected by the radiation-reflecting layer 33 on the heat-insulating cover 3, while the heat-insulating layer 34 reduces the heat leakage of the thermo roll 1 to the external environment. When the hot roller 1 needs to be cooled quickly after the heat setting operation is finished, the first heat-retaining shield Wen Zhaoti and the second heat-retaining shield 32 are rotated to rotate from the second position to the first position, as shown in fig. 2, then the cooling of the hot roller 1 and the spiral net is started, after the hot roller 1 and the spiral net are cooled, the spiral net is detached from the hot roller setting machine, then a new spiral net is tensioned on the hot roller 1, and the setting of the new spiral net is restarted.
This application can keep warm to the hot-rolling through having increased the heat preservation cover structure on the hot-rolling forming machine, has reduced the hot-rolling when stereotyped and the thermal interaction of surrounding environment, and the thermal loss that causes can also reduce to the effect that heat roller temperature fluctuation led to the fact the spiral net to stereotype behind the heat loss.
