TECHNICAL FIELD

[0001] The utility model relates to a thin film circulation air blowing heating structure which heats and conveys thin films in the thin film production process. BACKGROUND

[0002] With the rapid development of electronic information industry, high integration, high density and high speed of electronic equipment make the circuit or chip rapidly accumulate heat in the limited space, and whether the heat can be dissipated in time becomes the key to affect the service life, operation stability and safety performance of components. Polyimide (PI) film is widely used in the field of electronic and electrical as high-performance insulating material due to its excellent electrical performance, flame retardant performance, high temperature resistance and radiation resistance, which is incomparable to other plastic films such as nylon film, polyester film, polypropylene film and polyethylene film.

[0003] In the PI film production and conveying process, a structure is needed in the thin film conveying section, that is, the corresponding temperature can be maintained during the thin film conveying process, and the thin film can be supported to a certain extent. SUMMARY

[0004] The main purpose of the utility model is to provide a thin film circulation air blowing heating structure to better heat and convey the thin film.

[0005] The technical means adopted by the utility model are as follows. A thin film circulation air blowing heating structure is arranged in the thin film conveying section, which comprises an upper air blowing table and a lower air blowing table, a through space is formed between the upper and lower air blowing tables, and the thin film passes through the through space; the upper and lower air blowing tables are connected with a hot air supply section.

[0006] The upper air blowing table and the lower air blowing table are arranged in pairs in the upper and lower positions, and a plurality of air blowing tooth tables are arranged on the upper air blowing table and the lower air blowing table.

[0007] The length of the slit is matched with the width of the passing thin film.

[0008] The width of each air blowing tooth table is the same, and the width of the gap in the middle of the air blowing tooth table is also the same.

[0009] The positions of the slits on the upper and lower sides are completely opposite.

[0010] The hot air supply section comprises a fan, one end of the fan is connected with an electric heating device through a pipeline, the other end is connected with the upper air blowing table and the lower air blowing table to supply hot air, and the other end connected with the fan is connected with a hot air recovery port through a pipeline.

[0011] The hot air recovery port is located above the upper air blowing table.

[0012] The utility model discloses a beneficial effect: in the film conveying process, blow hot air to control temperature to film upper and lower simultaneously, in addition, the control of air volume can also support the film in conveying. BRIEF DESCRIPTION OF DRAWINGS

[0013] Figure 1 It is the whole structure schematic of the utility model.

[0014] Figure 2 It is another wind direction three -dimensional structure schematic of the utility model. CONCRETE IMPLEMENTATION

[0015] Please refer to Figure 1 And Figure 2 The utility model discloses a film circulation blow heating structure, set up in the film conveying section, its emphasis lies in, it includes upper blow -off platform 1 and lower blow -off platform 2, and the through space 3 is formed between upper blow -off platform and lower blow -off platform, and the film passes through the through space, and the upper blow -off platform 1 and lower blow -off platform 2 are connected with hot air supply section 4. The general design idea is in the film conveying process, blow hot air to control temperature to film upper and lower simultaneously, in addition, the control of air volume can also support the film in conveying.

[0016] In this embodiment, the upper blow -off platform 1 and lower blow -off platform 2 are correspondingly set up a plurality of blow -off tooth platform 5, and the blow -off tooth platform 5 is provided with transverse slit 6. The length of the slit is matched with the width of the film passing through. To more evenly and comprehensively heat blow -off to the film, and support the film, it also can be the horizontally uniform distribution's air hole, and also can reach the same effect.

[0017] Most preferably, the width of each blow -off tooth platform is same, and the width of the gap in the blow -off tooth platform is also same. Make the blow -off more evenly, and the slit position of upper and lower is completely opposite. The blow -off tooth platform here can be set very closely, and the density and number of tooth platform can be set according to demand, which can be selected by the person skilled in the art.

[0018] In addition, the hot air supply section 4 includes fan 41, one end of fan 41 is connected with electric heating device 42 through pipeline, the other end is connected with upper blow -off platform 1 and lower blow -off platform 2 to supply hot air, and the other end of electric heating device 42 connected with fan 41 is connected with hot air recovery port 43 through pipeline. The hot air recovery port 43 is located above the upper blow -off platform 1, since hot air generally flows upwards, and the arrangement is more conducive to hot air recovery. Utilizing this circulation structure can recycle hot air, more energy saving and environmental protection, reduce power consumption, and improve economic benefit.
