Description

Technical Field

[0001] This utility model belongs to the technical field of film manufacturing equipment, specifically relating to a main load-bearing heat preservation unit for a polyimide film production line, suitable for the housing structure of a casting machine or a horizontal stretching machine. Background Technology

[0002] Casting machines and cross-stretching machines are both essential equipment in polyimide film production lines. Due to the need for chemical film production, the outer side of the machine body needs to have good heat insulation and sealing functions. Both casting machines and cross-stretching machines need to be made of insulation board to effectively insulate and keep warm.

[0003] In existing technologies, steel plates or other metal plates are often attached with high-efficiency thermal insulation materials as the side walls of the box. They are usually set up as a whole. Since the steel strip casting machine is large and heavy, it not only requires more space for installation, but if the equipment is damaged in part, the entire side wall has to be replaced, or other more expensive designs have to be adopted, which is not conducive to the promotion and application of the current market. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a side insulation panel unit structure for a polyimide film production line, which can realize high-performance modular design, factory prefabrication, on-site assembly, on-site replacement, no site restrictions, convenient maintenance, and convenient adjustment.

[0005] This utility model first provides a side insulation panel unit for a polyimide film production line, comprising a main support frame, which includes a first support frame and a second support frame, with a first heat insulation layer disposed between the two. The first support frame and the second support frame are connected to form a three-dimensional support with an open inner and outer side. The first support frame is directly or indirectly connected to an inner side plate, and the second support frame is directly or indirectly connected to an outer side plate, forming a hollow cavity structure. The thickness of the hollow cavity can be extended by a third support frame. A heat insulation layer can be disposed in the hollow cavity to provide a high-strength heat insulation board with strong expansion function.

[0006] This utility model also provides a side insulation unit with a reserved opening on the main support frame. The reserved opening includes a reserved opening support frame, and a heat insulation layer is provided between the reserved opening support frame and the outer side panel. An insulated door is installed inside the reserved opening. The insulated door includes an outer peripheral panel, an inner panel, and an outer panel. A heat insulation layer is provided between the outer peripheral panel and the inner panel, and / or between the outer peripheral panel and the outer panel. An observation window is provided inside the insulated door. The observation window includes an inner frame and an outer frame, with a heat insulation layer between them. A double-glazed window is provided on the outer frame, and a heat insulation layer is provided between the double-glazed window and the outer panel.

[0007] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0008] Side insulation panel units for polyimide film production lines are typically used on the four sides of the housing of casting machines or horizontal stretching machines. Together with upper and lower load-bearing units, they form the entire housing. Unlike the main load-bearing unit, the side insulation panel unit does not require a high-strength counterweight frame such as channel steel. It only needs to be constructed using angle iron to form at least two layers of frames, with an insulation layer between each layer. The hollow cavity formed by the frames is filled with insulation cotton or other insulation materials, or arranged in layers for insulation, creating a thermal break-like insulation method. One or both of the inner and outer side panels can be used as a sandwich layer with only insulation panels to form a sandwich insulation method. This results in the entire main support frame using a three-layer thermal break insulation method, plus the panels achieving a three-layer insulation method, thus forming a double-stage thermal break insulation system. The cavity of the main support frame is filled with thermal insulation cotton, so that the inner and outer walls of the box panel do not come into direct contact. Based on the principle of thermal break insulation, it prevents the internal heat from being transferred to the outside and causing the outer surface of the box to overheat. Moreover, this solution has better mechanical performance and lower cost compared with the existing structure, while also ensuring the functional requirements such as sealing of the casting machine box.

[0009] The side insulation unit serves both inspection and observation functions, so the reserved opening has a relatively large space for installing inspection or observation doors. The reserved opening is constructed of panels or brackets, and an insulation layer is required between the inner or outer side panels it contacts. The reserved opening is housed in a cavity structure composed of multiple layers of similar insulation panels. The cavity is filled with insulation material or has an insulation layer, ensuring overall thermal insulation functionality. Attached Figure Description

[0017] This utility model provides a side view of a side insulation panel unit for a polyimide film production line, which solves the problems of high cost or poor insulation effect of existing technical solutions. It achieves better thermal insulation effect through structural improvement design, while the structure is relatively simple and the cost is relatively low.

[0018] like Figure 1 As shown, this utility model provides a side insulation panel unit for a polyimide film production line, which is mainly used for the housing structure of a casting machine or a horizontal stretching machine. The side insulation panel unit 3 is composed of an insulation structure and has a reserved opening 4 for installing external equipment, or maintenance doors or observation windows, etc.

[0019] like Figure 2 and Figure 3 As shown, the side insulation panel unit 3 includes a main support frame 30, which includes a first support frame 31 and a second support frame 32. A first heat insulation layer 33 is provided between the two. The first support frame 31 and the second support frame 32 are connected to form a three-dimensional support with an open inner and outer side. The first support frame 31 is directly or indirectly connected to an inner side plate 301, and the second support frame 32 is directly or indirectly connected to an outer side plate 302, forming a hollow cavity structure as a whole.

[0020] Please combine Figure 5 As shown, the first support frame 31 and the second support frame 32 can be formed into a square or rectangular frame by angle irons. The two frames are connected by one side of the angle irons, and the first heat insulation layer 33 is provided between the two frames. The other side of the angle iron serves as a side for connection and fixation to the inner side plate 301 and the outer side plate 302. In addition to having a surface that shields the open area, the inner side plate 301 and the outer side plate 302 are provided with connecting edges that fit the side of the angle irons. It is preferable that the width of the connecting edges is the same as the side width of the angle irons to improve the overall aesthetics.

[0021] like Figure 4 As shown, due to Figure 5In this design, the thickness of the two interlocking angle iron frames forming a hollow cavity is limited. A third support frame 34 can be added, connecting to one side of the inner side plate 301 or the outer side plate 302 to expand the space of the hollow cavity. As shown in the figure, the third support frame 34 is a square or rectangular frame formed by longitudinal plates with a slightly bent section on one side. One side is connected to one side of the angle iron of the second support frame 32, and the other side is connected to the connecting edge of the outer side plate 302 from the inside of the frame through the bent section. For further heat insulation, a second heat insulation layer 35 is provided on the surface of the third support frame 34 that contacts the outer side plate 302. The addition of the third support frame 34 can expand the overall thickness of the side insulation unit and further improve the insulation performance.

[0022] Look again Figure 3 and Figure 7 This reflects the overall structure of the side insulation unit, which, from the inside to the outside, consists of an inner side panel 301, a first support frame 31, a heat insulation layer 33, a second support frame 32, a third support frame 34, a heat insulation layer 35, and an outer side panel 302, and is internally filled with a heat insulation layer. Furthermore, regardless of the method used... Figure 4 The embodiment still adopts Figure 5 In this embodiment, a thermal insulation layer is provided within the hollow cavity. This thermal insulation layer can be a thermal insulation material filling the entire space, or it can be a multi-layered thermal insulation board. The side insulation unit is not a load-bearing unit. Multiple methods are used to achieve strong thermal insulation between the inner and outer sides, including an internal thermal insulation layer and a thermal insulation layer between the outer panel 302 and the frame it contacts. Generally, a single layer of material for the inner panel 301 and / or the outer panel 302 is sufficient to achieve excellent thermal insulation. If a reduction in cavity thickness or a pursuit of ultimate thermal insulation is desired, the inner panel 301 and / or the outer panel 302 can be a multi-layered thermal insulation board comprising an outer sealing plate, a thermal insulation board, and an inner sealing plate; furthermore, multiple layers of thermal insulation materials can be placed within it.

[0023] Furthermore, the main support frame 30 is provided with a reserved opening 4 for installing external equipment or maintenance doors, etc. Figure 2 As shown, to ensure the thermal insulation function of the reserved opening location, the reserved opening 4 includes a reserved opening support frame 41. A thermal insulation layer is provided between the reserved opening support frame 41 and the outer side plate 302, achieving thermal insulation between the reserved opening support frame 41 and the outside. Of course, a thermal insulation layer can also be provided on the inner side plate to further enhance the thermal insulation effect of the frame structure in contact with the outside at the reserved opening location.

[0024] Please combine Figure 5As shown, an insulated door 5 is installed inside the reserved opening. The insulated door 5 includes an outer peripheral panel 51, an inner panel 52, and an outer panel 53. The outer peripheral panel 51 includes the panels on both sides and the top of the door, forming a frame. A support plate 55 can be installed inside the frame. A heat insulation layer 54 is provided between the outer peripheral panel 51 and the inner panel 52, and / or between the outer peripheral panel 51 and the outer panel 53. A heat insulation layer is provided at the contact point between the insulated door 5 and the reserved opening 4 to block heat conduction. An observation window 6 is provided inside the insulated door 5. The observation window 6 includes an inner frame 61 and an outer frame 62, with a heat insulation layer between them. A double-glazed window is provided on the outer frame, and a heat insulation layer is provided between the double-glazed window and the outer panel 53.
