[0028] The present invention will be further described below with reference to the drawings and embodiments. Unless otherwise defined, the technical terms or scientific terms used in the present invention should have the ordinary meanings understood by those of ordinary skill in the art to which the present invention belongs. The above-mentioned features mentioned in the present invention or the features mentioned in the specific examples can be combined arbitrarily. These specific embodiments are only used to illustrate the present invention and do not limit the scope of the present invention.

[0029] Embodiment 1

[0030] As Figure 1 and Figure 2As shown in the figure, the present invention provides a heat insulation device for the hot air hood of a coating machine oven, which includes an installation unit, a heat insulation unit 2, and a coating machine 3. The mounting frame 1 of the installation unit is located outside the coating machine 3, and a second mounting part 12 is provided below the first mounting part 11 of the mounting frame 1. The first cross beam 111 of the first mounting part 11 is respectively connected to the first vertical beam 112 and the second vertical beam 113, and the second cross beam 121 of the second mounting part 12 is located below the first cross beam 111. A third vertical beam 122 is provided between the second cross beam 121 and the bottom of the oven of the coating machine 3. A plurality of hot air hoods 21 of the heat insulation unit 2 are sleeved outside both the first mounting part 11 and the second mounting part 12. The hot air hood 21 includes a first heat insulation cloth 211 and a second heat insulation cloth 212. The first heat insulation cloth 211 is connected to the first mounting part 11 through the first magic tape 22 and the third magic tape 24, and the second heat insulation cloth 212 is connected to the second mounting part 12 through the second magic tape 23 and the third magic tape 24.

[0031] The first heat insulation cloth 211 and the second heat insulation cloth 212 are spliced to form a seamless covering. The first heat insulation cloth 211 and the second heat insulation cloth 212 are fixed through the mounting frame 1 to form a hot air hood 21 covering the oven of the coating machine 3. The hot air hood 21 forms a closed heat insulation layer to reduce heat loss, reduce the diffusion of the heat of the oven of the coating machine 3 to the environment, and reduce the heating energy consumption. The low thermal conductivity of the hot air hood 21 is used to block heat conduction and reduce heat convection and radiation losses. Both the first heat insulation cloth 211 and the second heat insulation cloth 212 are transparent heat insulation cloths, which are convenient for observing the working state of the coating machine 1.

[0032] The installation unit adopts a layered frame structure, and the first mounting part 11 and the second mounting part 12 are distributed up and down. By adjusting the quantity and combination mode of the first heat insulation cloth 211 and the second heat insulation cloth 212, it can be adapted to the ovens of coating machines 3 with different sizes. At the same time, the hot air hood 21 is spliced by multiple pieces of the first heat insulation cloth 211 and the second heat insulation cloth 212 to disperse the thermal stress and avoid deformation of the overall structure due to high temperature.

[0033] The two ends of the first heat insulation cloth 211 are respectively provided with the wool surface and the hook surface of the first magic tape 22, and the wool surface and the hook surface of the first magic tape 22 of adjacent first heat insulation cloths 211 are adhesively connected.

[0034] The two ends of the second heat insulation cloth 212 are respectively provided with the wool surface and the hook surface of the second magic tape 23, and the wool surface and the hook surface of the second magic tape 23 of adjacent second heat insulation cloths 212 are adhesively connected.

[0035] The upper and lower sides of the first heat insulation cloth 211 and the upper and lower sides of the second heat insulation cloth 212 are respectively provided with the wool surface of the third magic tape 24. The first cross beam 111, the second cross beam 121, and the bottom of the oven of the coating machine 3 are respectively provided with the hook surface of the third magic tape 24, and the wool surface of the third magic tape 24 is adhesively connected to the hook surface of the third magic tape 24.

[0036] The mechanical engagement between the hook surfaces and the loop surfaces of the first Velcro 22, the second Velcro 23, and the third Velcro 24 provides reliable fixation while allowing flexible adjustment to accommodate thermal expansion. The first Velcro 22, the second Velcro 23, and the third Velcro 24 are tightly bonded to reduce heat leakage from the seams. By providing the first Velcro 22, the second Velcro 23, and the third Velcro 24, the first heat-insulating cloth 211 or the second heat-insulating cloth 212 can be disassembled or replaced without tools, reducing the downtime of the coater 3 and lowering the maintenance cost.

[0037] As Figure 3 and Figure 4 shown, fixing strips 25 are provided on the first vertical beam 112, the second vertical beam 113, and the third vertical beam 122. The fixing strips 25 on the first vertical beam 112 and the second vertical beam 113 are connected to the back of the hook surface of the first Velcro 22, and the fixing strip 25 on the third vertical beam 122 is connected to the back of the hook surface of the second Velcro 23.

[0038] The connection design of the fixing strip 25 with the first vertical beam 112, the second vertical beam 113, and the third vertical beam 122 further simplifies the installation steps of the hot air hood 21, supports quick disassembly and assembly, and adapts to the high-frequency maintenance requirements. At the same time, the double fixation of the fixing strip 25 with the first Velcro 22, the second Velcro 23, and the third Velcro 24 prevents the hot air hood 21 from falling off due to air flow vibration.

[0039] The width of the first heat-insulating cloth 211 is the same as the width between the adjacent second vertical beam 113, and the width between the adjacent first vertical beam 112 and the adjacent second vertical beam 113 is the same. The first heat-insulating cloth 211 and the second heat-insulating cloth 212 are adapted to the mounting frame 1 to ensure no exposed gaps, facilitating the stable connection of the first heat-insulating cloth 211 and the second heat-insulating cloth 212 and forming the heat-insulating effect of the hot air hood 21.

[0040] The width of the second heat-insulating cloth 212 is the same as the width between the adjacent third vertical beam 122.

[0045] S3. Connect the hook surface of the second magic tape 23 of the second heat-insulating cloth 212 to the third vertical beam 122, and then bond and connect the loop surface of the second magic tape 23 of the second heat-insulating cloth 212 to the hook surface of the second magic tape 23 of the adjacent second heat-insulating cloth 212.

[0046] S4. Bond and connect the loop surface of the third magic tape 24 on the upper and lower sides of the first heat-insulating cloth 211 to the hook surface of the third magic tape 24 on the two first cross beams 111 on both sides of the first installation part 11.

[0047] S5. Bond and connect the loop surface of the third magic tape 24 on the upper and lower sides of the second heat-insulating cloth 212 to the hook surface of the third magic tape 24 on the two second cross beams 121 on both sides of the second installation part 12 and on the oven of the coater 3.

[0048] During installation, the splicing method of the first heat-insulating cloth 211 and the second heat-insulating cloth 212 can be adjusted according to the size of the oven of different coaters 3. Installation or replacement can be completed without professional skills, and the first heat-insulating cloth 211 and the second heat-insulating cloth 212 can be replaced separately.
