Description

Technical Field

[0001] The utility model relates to the technical field of film cooling equipment, in particular to a film double-sided cooling device. Background Art

[0002] In the film production line, it is often necessary to quickly cool the film to achieve the purpose of rapid shaping, so as to avoid the film from stretching to varying degrees due to tension changes during the subsequent transmission and winding process, thereby ensuring the quality of the film. The cooling effect of the film is also affected by environmental factors. Common film cooling devices cannot be adjusted according to the cooling status, and thus cannot guarantee the stability of the cooling effect. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a thin film double-sided cooling device to solve the problem that the traditional cooling device cannot adjust the cooling effect according to the real-time cooling situation.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a double-sided cooling device for a thin film, comprising a cooling roller group, wherein the cooling roller group is provided with a swinging plate, on which two cooling rollers are rotatably arranged, the two cooling rollers are arranged in parallel and at a distance, and a film is inserted and passed between the two cooling rollers; the swinging axis of the swinging plate is coaxially arranged with the rotating axis of the cooling roller on the upper side; supporting rollers are respectively provided on both sides of the cooling roller group, and the film is attached to the side of the supporting roller away from the cooling roller group; a temperature sensing module is provided corresponding to the portion of the film after passing through the cooling roller group, and the signal output end of the temperature sensing module is electrically connected to the control signal receiving end of the swinging plate driving device.

[0005] Furthermore, the support roller is slidably arranged along the guide groove, and the guide groove is extended vertically.

[0006] Further, the swing plate is swingably arranged between a vertical position state and a position state deflected toward the film introduction direction.

[0007] Furthermore, the guide groove is arranged obliquely along the swinging and deflecting direction of the swing plate.

[0008] Furthermore, the rotating shafts of the two cooling rollers are connected through a gear set, and the gear set includes two gears with equal numbers of teeth and meshing with each other, and the rotating shaft of the lower cooling roller is connected to the output end of the rotation driving device.

[0009] Furthermore, tension sensors are provided on the support seats on both sides of the support roller, and the tension signal output end of the tension sensor is electrically connected to the control signal receiving end of the sliding drive device corresponding to the support roller.

[0010] Beneficial effects: A double-sided film cooling device of the present utility model controls the coordinated movement of the cooling roller group and the support rollers on both sides thereof by detecting the temperature of the film after cooling. By using the swing of the cooling roller group within a small angle range in cooperation with the movement of the support rollers within a certain stroke, the attachment area between the double sides of the film and the cooling rollers is adjusted, thereby adjusting the double-sided cooling effect of the film by controlling the size of the cooling area. Description of the Drawings

[0011] Figure 1 It is a schematic diagram of the overall structure distribution of an embodiment of the present utility model in a certain state. Detailed Embodiment

[0012] The present utility model will be further described in conjunction with the accompanying drawings.

[0013] As shown in the attached Figure 1 A double-sided film cooling device as described above includes a cooling roller group. A swing plate 1 is provided on the cooling roller group. Two cooling rollers 2 are rotatably provided on the swing plate 1. The two cooling rollers 2 are arranged in parallel at a certain distance. A film 3 is interspersed and wound around between the two cooling rollers 2; the swing axis of the swing plate 1 is arranged coaxially with the rotating shaft of the upper cooling roller 2; Support rollers 4 are respectively arranged on both sides of the cooling roller group. The film 3 is attached to the side of the support roller 4 away from the cooling roller group; A temperature sensing module 6 is provided corresponding to the part of the film 3 after passing through the cooling roller group. The signal output end of the temperature sensing module is electrically connected to the control signal receiving end of the driving device of the swing plate 1.

[0014] In this solution, the film is cooled by passing it around the cooling roller group. The cooling roller is a hollow roller body, and a cooling medium, such as cooling water, flows through it. When the film is in contact with the roller, heat is exchanged with the internal cooling medium, thereby achieving the purpose of rapid cooling. The two side support rollers play a role in guiding and supporting the film before it enters the cooling roller group and after it passes through the cooling roller group, ensuring that the film always maintains a stable straight state and preventing the film from having a gap with the cooling roller surface due to slack, which may affect the cooling effect. By swinging the cooling roller group, when it swings to different angles, the contact area between the film and the two cooling rollers is different. The larger the area, the more sufficient the heat exchange time and the better the heat exchange effect. The smaller the area, the shorter the heat exchange time and the corresponding reduction in the heat exchange effect. The temperature sensing module detects the temperature of the cooled film, determines whether the temperature of the cooled film reaches the preset temperature, and adjusts the swing direction of the swing plate accordingly based on whether the temperature is higher or lower than the preset temperature, so that the cooling effect changes accordingly, ensuring that the temperature of the output film is stably within the preset temperature range.

[0015] The support roller 4 is slidably arranged along the guide groove 5, and the guide groove 5 is extended vertically. The sliding arrangement of the support roller can change the guiding direction of the film. When the contact area between the film and the cooling roller is increased by adjusting the swing plate, the support roller can be slid to move away from the adjacent cooling roller, thereby further increasing the adhesion area between the film and the cooling roller surface, thereby achieving the purpose of further enhancing the cooling effect.

[0016] The swing plate 1 is swingably arranged between a vertical position state and a slanted position state toward the film introduction direction. In the vertical position state, two cooling rollers are arranged vertically and aligned; in the slanted position state, the lower cooling roller intersects with the upper cooling roller and is slanted toward the film introduction side. When the cooling attachment area needs to be increased, the swing plate is controlled to swing toward the vertical position state, and when the cooling attachment area needs to be reduced, the swing plate is controlled to swing toward the slanted position state.

[0017] The guide groove 5 is arranged obliquely along the swinging and deflecting direction of the swing plate 1. The support roller is vertically away from the adjacent cooling roller, while being horizontally close to the cooling roller group, so that the film portion before the cooling roller group and the film portion after the cooling roller group are led out can be more closely attached to the adjacent cooling roller in a large area to achieve the expected cooling effect.

[0018] The rotating shafts of the two cooling rollers 2 are connected through a gear set, which includes two gears with equal teeth and meshing with each other, and the rotating shaft of the lower cooling roller 2 is connected to the output end of the rotation drive device. It can ensure that the two cooling rollers always maintain a synchronous rotation state, thereby ensuring that the tension generated by the film part between the two cooling rollers always maintains a stable state, avoiding the problem of stretching the middle film section caused by the difference in static friction between the film and the two cooling roller surfaces.

[0019] The support seats on both sides of the support roller 4 are provided with tension sensors, and the tension signal output end of the tension sensor is electrically connected to the control signal receiving end of the sliding drive device corresponding to the support roller 4. When the cooling attachment area needs to be adjusted, the support rollers on both sides should work in coordination with the swing plate. Since the film is attached to the relative outer side of the support roller, the tension sensor provided on the support roller can sense the film tension change caused by the swing of the swing plate, thereby accurately controlling the sliding distance and speed of the support roller along the guide groove, so that while ensuring the corresponding change in the cooling area, the tension change on the film surface tends to be stable, thereby avoiding the film from being damaged during the adjustment process.

[0020] The temperature sensing module 6 includes two temperature sensors symmetrically arranged on both sides of the film. The two temperature sensors are respectively electrically connected to the corresponding support roller sliding drive modules on both sides, so that the positions of the support rollers on both sides can be adjusted respectively according to the temperature changes on both sides, and then the positions of the support rollers after adjustment can be determined through the different cooling efficiencies on both sides of the film, so as to achieve the purpose of adjusting the double-sided cooling effect respectively.

[0021] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
