Description

Technical Field

[0001] The utility model relates to a heating structure for the edge of a horizontal pull box in a film production process. Background Art

[0002] With the rapid development of the electronic information industry, the high integration, high density, and high speed of electronic devices have led to a rapid accumulation of heat in extremely small, limited spaces within circuits or chips. The ability to dissipate heat in a timely manner has become a key factor affecting the lifespan, operational stability, and safety of components. Polyimide (PI) film, with its excellent electrical properties, flame retardancy, high-temperature resistance, and radiation resistance, is widely used as a high-performance insulating material in the electronic and electrical fields. This performance is 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 maintain a certain temperature in the horizontal pull box. In addition to increasing the thermal insulation performance of the horizontal pull box, the heating function of the horizontal pull box also needs to be improved. Utility Model Content

[0004] The main purpose of the utility model is to provide a heating structure for the edge of a horizontal pull box to increase the heating function of the horizontal pull box, so as to better maintain the overall temperature of the horizontal pull box and increase the controllability of its temperature.

[0005] The technical means adopted by the present invention are as follows: a heating structure for the edge of a horizontal pull box, which is arranged in a horizontal pull box unit, and a heating component is installed inside the side wall of the horizontal pull box unit. The heating component is arranged on at least one side of the inside of the side wall, and the heating part is connected to the temperature control system.

[0006] The heating components are arranged on both sides of the inner portion of the side portion.

[0007] A plurality of operating doors are provided on at least one side of the horizontal pull box unit.

[0008] The heating component arranged on the side corresponding to the operating door is a detachable structure.

[0009] The heating components arranged on the side corresponding to the operating door are arranged at intervals, and a distance of the operating door is left between each heating component.

[0010] The heating component is a heating coil, a heating rod or a hot air blower.

[0011] The beneficial effects of the utility model are: a heating structure for the edge of a horizontal pull box is provided to increase the heating function of the horizontal pull box, so as to better maintain the overall temperature of the horizontal pull box and increase the controllability of its temperature. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a schematic diagram of the overall structure of the horizontal pull box in the present utility model.

[0013] Figure 2 It is the perspective structure schematic view of the horizontal pull box from the film import direction in the utility model.

[0014] Figure 3 It is the arrangement schematic view of the heating component and the maintenance door in the edge heating structure of the utility model. CONCRETE IMPLEMENTATION

[0015] Please refer to Figures 1-3 The utility model discloses an edge heating structure of horizontal pull box, which is mainly directed to the structural improvement of the chemical imidized polyimide film horizontal pull box. The film needs accurate heating and temperature control before being pulled in the horizontal pull box, so that the temperature in the horizontal pull box is maintained.

[0016] The horizontal pull box structure is as shown in Figure 1 It contains horizontal pull box unit 1, which is provided with film import 11 and film export 12. The film enters from the film import 11 and exits from the film export 12. The horizontal pull box unit 1 can be provided with one or more according to the needs. In the embodiment, two groups are provided, which are arranged in a head-to-tail mode.

[0017] The utility model discloses an edge heating structure of horizontal pull box, which is arranged in the horizontal pull box unit 1. The sidewall of the horizontal pull box unit 1 is internally provided with a heating component L. The heating component L is arranged on at least one side of the sidewall. The heating component L is connected to a temperature control system (not shown in the figure). When it is necessary to increase the temperature of the horizontal pull box, the temperature control system can control the heating component L to perform heating operation. The heating component L can be arranged on both sides of the sidewall or only on one side. The heating component can be any commonly used heating device, such as heating coil, heating rod or hot air blower, which can be arranged according to the needs.

[0018] At least one side of the horizontal pull box unit 1 is provided with a plurality of operation doors 3. The operation doors are mainly used for conveniently performing the conventional operations such as tensioning or winding the internal film. In this case, the heating component L arranged on the side corresponding to the operation door 3 can be a detachable structure to facilitate operation.

[0019] In addition, the heating component L arranged on the side corresponding to the operation door 3 can also be arranged at intervals, and the distance between each heating component L is left empty for the operation door 3, as shown in Figure 3 ​
