[0002] In the production process of coating machines, the insulation performance of the oven's hot air hood directly affects energy utilization and production stability. Traditional coating machine oven hot air hoods typically use a fixed insulation layer, which has the following problems: Inconvenient insulation layer maintenance: When local insulation material ages or is damaged, the entire structure must be disassembled and replaced, which is time-consuming, labor-intensive, and affects production efficiency. Insufficient installation flexibility: Traditional insulation structures are mostly fixed, making it difficult to adapt to different specifications of coating machine ovens, resulting in poor versatility. Poor insulation sealing: Fixed connections are prone to gaps due to equipment vibration or thermal expansion and contraction, leading to heat loss and increased energy consumption. Low material utilization: The integral insulation structure cannot individually replace damaged parts, resulting in material waste. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. Unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The features mentioned above or in the specific examples mentioned in this invention can be combined arbitrarily, and these specific embodiments are only used to illustrate this invention and are not intended to limit the scope of this invention.
[0022] Example 1
[0023] like Figure 1 and Figure 2 As shown, this utility model provides a heat preservation device for a hot air hood of a coating machine oven, including an installation unit, a heat preservation 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 horizontal beam 111 of the first mounting part 11 is connected to the first vertical beam 112 and the second vertical beam 113 respectively, and the second horizontal beam 121 of the second mounting part 12 is located below the first horizontal beam 111. A third vertical beam 122 is provided between the second horizontal beam 121 and the bottom of the coating machine oven 3. Several heat preservation units 2 hot air hoods 21 are fitted over both the first mounting part 11 and the second mounting part 12. The hot air hood 21 includes a first heat preservation cloth 211 and a second heat preservation cloth 212. The first heat preservation cloth 211 is connected to the first mounting part 11 via a first Velcro 22 and a third Velcro 24, and the second heat preservation cloth 212 is connected to the second mounting part 12 via a second Velcro 23 and a third Velcro 24.
[0024] The first insulation cloth 211 and the second insulation cloth 212 are spliced together to form a seamless cover. The first insulation cloth 211 and the second insulation cloth 212 are fixed by the mounting bracket 1, forming a hot air hood 21 covering the oven of the coating machine 3. The hot air hood 21 forms a closed insulation layer to reduce heat loss and the diffusion of heat from the coating machine 3 oven to the environment, thus reducing heating energy consumption. The low thermal conductivity of the hot air hood 21 blocks heat conduction, reducing heat convection and radiation losses. Both the first insulation cloth 211 and the second insulation cloth 212 are transparent, facilitating observation of the working status of the coating machine 1.
[0025] The installation unit adopts a layered frame structure, with the first installation part 11 and the second installation part 12 distributed vertically. By adjusting the quantity and combination of the first insulation cloth 211 and the second insulation cloth 212, it can be adapted to the coating machine 3 oven of different sizes. At the same time, the hot air hood 21 is spliced together by multiple pieces of the first insulation cloth 211 and the second insulation cloth 212 to disperse thermal stress and prevent the overall structure from deforming due to high temperature.
[0026] The first insulation cloth 211 has a first hook and loop fastener 22 rough side and a first hook and loop fastener 22 hook side at both ends, and the first hook and loop fastener 22 rough side and the first hook and loop fastener 22 hook side of adjacent first insulation cloths 211 are bonded together.
[0027] The second insulation cloth 212 has a second hook and loop fastener 23 rough side and a second hook and loop fastener 23 hook side at both ends, and the second hook and loop fastener 23 rough side and the second hook and loop fastener 23 hook side of adjacent second insulation cloths 212 are bonded together.
[0028] The upper and lower sides of the first insulation cloth 211 and the upper and lower sides of the second insulation cloth 212 are provided with the rough surface of the third hook and loop fastener 24. The bottom of the first crossbeam 111, the second crossbeam 121 and the oven of the coating machine 3 are all provided with the hook surface of the third hook and loop fastener 24. The rough surface of the third hook and loop fastener 24 is bonded to the hook surface of the third hook and loop fastener 24.
[0029] The mechanical interlocking of the hook and loop sides of the first hook and loop fastener 22, the second hook and loop fastener 23, and the third hook and loop fastener 24 provides reliable fixation while allowing for flexible adjustment to accommodate thermal expansion. The tight adhesion of the first hook and loop fastener 22, the second hook and loop fastener 23, and the third hook and loop fastener 24 reduces heat leakage from the seams. By incorporating the first hook and loop fastener 22, the second hook and loop fastener 23, and the third hook and loop fastener 24, the first insulation cloth 211 or the second insulation cloth 212 can be removed or replaced without tools, reducing downtime of the coating machine 3 and lowering maintenance costs.
[0030] like Figure 3 and Figure 4 As shown, the first vertical beam 112, the second vertical beam 113 and the third vertical beam 122 are all provided with fixing strips 25. The fixing strips 25 on the first vertical beam 112 and the second vertical beam 113 are connected to the back of the hook side of the first Velcro 22, and the fixing strip 25 on the third vertical beam 122 is connected to the back of the hook side of the second Velcro 23.
[0031] The connection design between the fixing strip 25 and 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 cover 21, supports quick disassembly and assembly, and adapts to the needs of high-frequency maintenance. At the same time, the double fixing of the fixing strip 25 with the first hook and loop fastener 22, the second hook and loop fastener 23 and the third hook and loop fastener 24 prevents the hot air cover 21 from falling off due to airflow vibration.
[0032] The width of the first insulation cloth 211 is the same as the width between adjacent second vertical beams 113, and the width between adjacent first vertical beams 112 and adjacent second vertical beams 113 is the same. The first insulation cloth 211 and the second insulation cloth 212 are adapted to the mounting frame 1 to ensure no exposed gaps, which facilitates the stable connection of the first insulation cloth 211 and the second insulation cloth 212 and forms the insulation effect of the hot air hood 21.
[0033] The width of the second insulation cloth 212 is the same as the width between the adjacent third vertical beam 122.
[0034] Example 2
[0035] A method for using a hot air hood insulation device for a coating machine oven, using the hot air hood insulation device of Example 1, includes the following steps:
[0036] S1. Fix the fixing strip 25 to the first vertical beam 112, the second vertical beam 113 and the third vertical beam 122, and fix the hook side of the third Velcro 24 to the first horizontal beam 111, the second horizontal beam 121 and the bottom of the coating machine 3 oven.
[0037] S2. Connect the first hook side of the first Velcro 22 of the first insulation cloth 211 to the first vertical beam 112 and the second vertical beam 113 in sequence, and then bond the rough side of the first Velcro 22 of the first insulation cloth 211 to the hook side of the first Velcro 22 of the adjacent first insulation cloth 211.
[0038] S3. Connect the hook side of the second Velcro 23 of the second insulation cloth 212 to the third vertical beam 122, and then bond the rough side of the second Velcro 23 of the second insulation cloth 212 to the hook side of the second Velcro 23 of the adjacent second insulation cloth 212.
[0039] S4. Adhere and connect the rough side of the third hook and loop fastener 24 on the upper and lower sides of the first insulation cloth 211 to the hook side of the third hook and loop fastener 24 on the first crossbeam 111 on both sides of the first mounting part 11.
[0040] S5. Adhere and connect the rough side of the third hook and loop fastener 24 on the upper and lower sides of the second insulation cloth 212 to the second crossbeam 121 on both sides of the second mounting part 12 and the hook side of the third hook and loop fastener 24 on the oven of the coating machine 3.
[0041] During installation, the splicing method of the first insulation cloth 211 and the second insulation cloth 212 can be adjusted according to the different sizes of the coating machine 3 oven. No professional skills are required to complete the installation or replacement. The first insulation cloth 211 and the second insulation cloth 212 can be replaced separately.
[0042] Therefore, the present invention provides a heat preservation device for the hot air hood of a coating machine oven with the above-mentioned structure. It adopts an independent modular structure for the first and second insulation cloths, which are quickly connected by Velcro. When a piece of insulation cloth is damaged, it can be directly disassembled and replaced without stopping the machine to disassemble the entire structure, thus shortening maintenance time and significantly improving production continuity.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
