Description

Technical Field

[0001] This utility model relates to a heat insulation structure for the side of a horizontally stretched box during the film production process. Background Technology

[0002] With the rapid development of the electronics and information industry, the high integration, high density, and high speed of electronic devices cause circuits or chips to accumulate heat rapidly within a very small and limited space. The ability to dissipate heat in a timely manner has become crucial to the lifespan, operational stability, and safety performance of components. Polyimide (PI) film, with its excellent electrical properties, flame retardant properties, high temperature resistance, and radiation resistance, is widely used as a high-performance insulating material in the electronics and electrical fields, unmatched by other plastic films such as nylon film, polyester film, polypropylene film, and polyethylene film.

[0003] During the production of PI film, the film needs to be kept at a certain temperature in the stretching box. In addition to heating, the insulation of the stretching box also needs to be improved. Utility Model Content

[0004] The main purpose of this utility model is to provide a side insulation structure for a horizontal pull box, so as to increase the insulation function of the horizontal pull box and facilitate disassembly during operation.

[0005] The technical means adopted by this utility model are as follows: a side insulation structure for a horizontal pull box, which is set in the horizontal pull box unit. The side wall of the horizontal pull box unit is equipped with vertically suspended side steel plates on both sides, and the side steel plates are detachable.

[0006] The top of the edge steel plate has an acute-angle bend groove, and the top of the horizontal pull box unit is equipped with a reverse bend groove corresponding to the acute-angle bend groove. The acute-angle bend groove and the reverse bend groove hook each other, thereby suspending and fixing the edge steel plate.

[0007] The horizontal pull box unit is provided with several operating doors on at least one side.

[0008] The height of the edge steel plate exceeds the position of the membrane and has operating space at the bottom.

[0009] The edge steel plate is a single piece of steel plate that matches the length of the horizontal pull box unit.

[0010] The edge steel plate is a structure of several steel plates, and the total length after assembly matches the length of the horizontal pull box unit.

[0011] The beneficial effects of this utility model are as follows: by using a simple structure with steel plates on both sides, it can not only play a good role in heat preservation through thermal radiation, but also be easily disassembled for maintenance work such as membrane stretching and membrane hooking.

[0015] Please see Figure 1-3 As shown, this utility model provides a side insulation structure for a horizontal stretch box, which is mainly an improvement on the structure of a chemically imidized polyimide film horizontal stretch box. The film is stretched forward in the horizontal stretch box, requiring precise heating and temperature control to maintain a certain temperature inside the horizontal stretch box.

[0016] Horizontal pull box structure as Figure 1 As shown, it includes a horizontal pulling box unit 1, which has a film inlet 11 and a film outlet 12. The film enters from the film inlet 11 and exits from the film outlet 12. One or more horizontal pulling box units 1 can be provided as needed; in this embodiment, two sets are shown in the attached drawings, connected end-to-end. Figure 2 As shown, this utility model discloses a side insulation structure for a horizontal pull-out box, which is installed in the horizontal pull-out box unit 1. Vertically suspended side steel plates 4 are installed on both sides of the inner side wall of the horizontal pull-out box unit 1. These side steel plates 4 are detachable and preferably made of stainless steel. Utilizing these suspended side steel plates 4, the insulation effect of the horizontal pull-out box unit 1 is further improved through heat radiation. With the support of the side steel plates on both sides, heat can be better maintained at the film position, resulting in better insulation and heating effects for the entire horizontal pull-out box, while also saving energy and meeting the requirements of energy conservation and emission reduction.

[0017] like Figure 3 As shown, the top of the edge steel plate 4 has an acute-angle bending groove 41, and the top of the horizontal pull box unit 1 has a reverse bending groove 42 corresponding to the acute-angle bending groove 41. The acute-angle bending groove 41 and the reverse bending groove 42 hook each other, thereby suspending and fixing the edge steel plate 4. This design adopts the simplest approach, making the installation and disassembly of the steel plate very convenient, and also facilitating maintenance and replacement without increasing additional costs.

[0018] In addition, at least one side of the horizontal pulling box unit 1 is provided with several operating doors 3. The operating doors are mainly used for convenient tensioning or rolling of the internal film. During operation, it is important to remove the corresponding side steel plate 4. Therefore, the side steel plate is designed with the simple structure described above to facilitate operation.

[0019] For the purpose of precise control of thermal radiation heat, the height of the side steel plate 4 exceeds the film position A and has operating space at the bottom. It does not need to extend to the bottom of the horizontal pull box unit 1. In addition to saving materials, this setting is also to facilitate the disassembly of the side steel plate and leave enough operating space.

[0020] The edge steel plate 4 is a single piece of steel plate that matches the length of the horizontal pull box unit 1, or it can be a structure of several steel plates. The total length after assembly can match the length of the horizontal pull box unit 1. This split structure also facilitates partial disassembly and replacement.
