In order to solve the problem that the heat insulation structure is relatively complex, the heat insulation and thermal insulation effect are poor, and the sealing is not tight during the heat preservation process, resulting in heat leakage, and the good heat preservation effect cannot be achieved, a heat insulation layer is arranged between the heat preservation box body and the spinning box body to reduce the heat loss in the spinning box body, and an inorganic nano high-efficiency energy-saving material layer is arranged. The inorganic nano high-efficiency energy-saving material layer has the advantages of low density, high resistance and low thermal conductivity, which further prevents the heat loss in the spinning box body, and a high-temperature resistant glass cloth is arranged. The glass cloth has the properties of insulation, heat insulation, corrosion resistance, non-combustion, high temperature resistance, high strength, etc. A high-temperature resistant reflective aluminum foil cloth is arranged. The aluminum foil cloth has the characteristics of smooth surface, high light reflectivity, large longitudinal and transverse tensile strength, airtightness, watertightness, good sealing performance, etc., which reflects the heat on the spinning box to the spinning box body, further reducing heat loss.

Specific embodiments

[0021] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below with reference to the embodiments and the accompanying drawings, but the implementation manners of the present utility model are not limited thereto.

[0022] As Figure 1-Figure 3 shown, this embodiment provides a heat preservation structure based on a spinning box, including a base 1 and a spinning box 2 installed on the top of the base 1. An outer protective shell 3 is provided outside the spinning box 2, and the outer protective shell 3 wraps the side of the spinning box 2. A pressing plate 6 parallel to the side of the spinning box 2 is provided inside the outer protective shell 3. A first heat insulating cotton 8 is filled between the pressing plate 6 and the outside of the spinning box 2. A second heat insulating cotton 9 is filled between the outside of the pressing plate 6 and the inside of the outer protective shell 3. Extrusion mechanisms 7 for moving the pressing plate 6 towards the spinning box 2 are provided on the side edges of the outer protective shell 3.

[0023] Overall working principle: When sealing the spinning box 2, first cover the outer protective shell 3 outside the protective box 2 to completely wrap the protective box 2, and then fill the first heat insulating cotton 8 between the pressing plate 6 and the outside of the spinning box 2. After the filling is completed, use the extrusion mechanism 7 to press the first heat insulating cotton 8 tightly to fit closely with the spinning box 2. After the pressing plate 6 is pressed, then fill the second heat insulating cotton 9 between the outside of the pressing plate 6 and the outer protective shell 3 to ensure the heat preservation effect of the spinning box 2.

[0024] In this embodiment, there are three groups of pressing plates 6, and the length of the pressing plate 6 at the top of the spinning box 2 is greater than the distance between the pressing plates 6 on both sides of the spinning box 2.

[0025] Local working principle: The pressing plate 6 can also form an isolation for the spinning box 2 after being extruded, improving the heat preservation effect during use.

[0026] In this embodiment, a vacuum chamber 4 is opened on the inner wall of the outer protective shell 3, and the end cross-sectional view shape of the vacuum chamber 4 is a U-shaped, and the vacuum chamber 4 wraps the spinning box 2.

[0027] Local working principle: By setting the vacuum box 4, vacuum heat insulation can be carried out, and the heat preservation effect is better.

[0028] In this embodiment, the inner wall of the outer protective shell 3 is coated with a heat reflecting layer 5 , and the heat reflecting layer 5 completely fits the inner wall of the outer protective shell 3 .

[0029] Local working principle: The setting of the heat reflection layer 5 can reflect heat and has a good heat blocking effect.

[0030] In this embodiment, the extrusion mechanism 7 includes a sleeve 10, a piston 11, a push rod 12 and an inflation component. The sleeve 10 is vertically arranged on the inner side of the heat reflecting layer 5. The piston 11 is slidably installed inside the sleeve 10.

[0031] Local working principle: After the first thermal insulation cotton 8 is filled, the interior of the sleeve 10 is inflated by using the inflation assembly, the internal pressure of the sleeve 10 increases, the piston 11 is controlled to slide, and the pressure plate 6 is tightened. In addition, when the device is working, the interior of the outer shell 3 has a certain temperature, which will cause the internal gas of the sleeve 10 to expand, thereby increasing the squeezing effect on the first thermal insulation cotton 8.

[0032] In this embodiment, the inflation assembly includes an air pipe 13 and a connector 14 . The air pipe 13 is connected between adjacent sleeves 10 . The air pipe 13 connects the multiple groups of sleeves 10 to each other. The connector 14 is installed at one end of the air pipe 13 .
