Description

Technical Field

[0001] This utility model relates to the field of thin film processing technology, specifically to a high-barrier thin film composite flattening device. Background Technology

[0002] High-barrier specialty films are widely used in the food, pharmaceutical, and electronics industries. These films are required to have high barrier properties, flatness, and composite strength. However, existing technologies suffer from poor flatness during the film winding process, which affects film quality. Therefore, a flattening device is needed to improve this.

[0003] The prior art, disclosed in patent document CN222523811U, provides the following technical solution: a plastic film flattening device. This invention allows the mounting plate to descend, enabling the rollers on the conveyor belt to contact the surface of the plastic film and apply pressure. After contact, the rollers move along the conveyor belt's direction, continuously smoothing the plastic film outwards from both sides to prevent wrinkles during winding.

[0004] In the above technical solution, the rolling balls on the conveyor belt contact the surface of the plastic film and smooth the film by rolling. However, the rolling balls on both sides can only smooth the two sides of the film, which is not comprehensive enough. Moreover, the smoothing speed by rolling the balls is relatively slow, and it may be necessary to roll multiple times to achieve a smooth effect. Utility Model Content

[0005] The purpose of this invention is to provide a high-barrier film composite flattening device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-barrier film composite leveling device, comprising a support, wherein a film leveling device is installed in the middle of the upper end of the support.

[0007] The film leveling device includes a support plate, with connecting plates fixedly connected to the bottom sides of both ends of the support plate. T-shaped sliders are fixedly connected to the bottom sides of the connecting plates. A heating roller is rotatably connected between the two T-shaped sliders via bearings. One end of the heating roller passes through one of the T-shaped sliders. A heating cavity is formed in the side wall of the heating roller. A first air-collecting hollow plate is provided at one end of the heating roller, and a second air-collecting hollow plate is provided at the other end. A hollow tube is fixedly connected to the middle of the heating roller. One end of the hollow tube communicates with the first air-collecting hollow plate, and the other end passes through the second air-collecting hollow plate. Both the first and second air-collecting hollow plates have a hollow design around their perimeter and are connected to the heating cavity. Exhaust holes are formed at both ends of the second air-collecting hollow plate, which communicates with the outside environment through these exhaust holes.

[0008] In the above technical solution, a heating chamber is opened inside the heating roller. When the hot air blown out by the hot air blower enters the hollow tube, it enters the heating chamber through the air collecting hollow plate, so that the heating roller is heated and can smooth the film that is transmitted. The heat is evenly distributed, so that a consistent flatness effect is achieved in the width of the film. Moreover, due to the temperature and pressure of the heating roller, the heating roller can achieve the effect of film flatness in a short time.

[0009] As a further preferred embodiment of this technical solution, guide rollers are rotatably connected to both sides of the upper end of the bracket, with the height of one guide roller being slightly higher than the height of the other guide roller.

[0010] As a further preferred embodiment of this technical solution, the front and rear inner walls of the middle part of the bracket are provided with through grooves, and sliding grooves are provided on both sides of the through grooves. The outer wall of the T-shaped slider is slidably connected to the inner wall of the through groove.

[0011] As a further preferred embodiment of this technical solution, the inner wall of the groove is slidably connected to the protrusions at both ends of the support plate.

[0012] In the above technical solution, the T-shaped slider slides in the groove during adjustment, and both ends of the support plate slide in the groove, which can improve the stability of the heating roller during adjustment.

[0013] As a further preferred embodiment of this technical solution, an electric push rod is installed at the top of the middle part of the bracket. The output end of the electric push rod is bolted to the support plate. Telescopic rods are provided on both the front and rear sides of the electric push rod, and the telescopic ends of the telescopic rods are bolted to the support plate.

[0014] In the above technical solution, the height of the heating roller can be adjusted according to the film thickness.

[0015] As a further preferred embodiment of this technical solution, a hot air blower is installed at one end of the top middle section of the bracket, and a connecting pipe is provided at the air outlet end of the hot air blower. The connecting pipe is connected to the hollow tube through a bearing.

[0016] As a further preferred embodiment of this technical solution, a pressing roller is rotatably connected to the lower part of the middle of the bracket, and the pressing roller is located directly below the heating roller.

[0017] This utility model provides a high-barrier thin-film composite flattening device, which has the following beneficial effects:

[0018] (1) The present invention opens a heating chamber in the heating roller. When the hot air blown out by the hot air blower enters the hollow tube, it enters the heating chamber through the air collecting hollow plate, so that the heating roller is heated and can smooth the film that is transmitted. The heat is evenly distributed, so that a consistent flatness effect is achieved in the width of the film. Moreover, due to the temperature and pressure of the heating roller, the heating roller can achieve the effect of film flatness in a shorter time, and the flatness efficiency is better.

[0019] (2) The present invention can adjust the height of the heating roller according to the film thickness by means of the electric push rod and the telescopic rod. During adjustment, the T-shaped slider slides in the groove and the two ends of the support plate slide in the groove, which can improve the stability of the heating roller during adjustment.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] This utility model provides a technical solution: such as Figure 1As shown in this embodiment, a high-barrier film composite flattening device includes a support 1. Guide rollers 11 are rotatably connected to both sides of the upper end of the support 1. The height of one guide roller 11 is slightly higher than the height of the other guide roller 11. A film flattening device 2 is installed in the middle of the upper end of the support 1.

[0027] like Figure 1 and Figure 2 As shown, the film leveling device 2 includes a support plate 24. The front and rear inner walls of the support 1 are provided with through grooves 21, and sliding grooves 22 are provided on both sides of the through grooves 21. The outer wall of the T-shaped slider 27 is slidably connected to the inner wall of the through groove 21, and the inner wall of the sliding groove 22 is slidably connected to the protrusions at both ends of the support plate 24. An electric push rod 23 (model YS607) is installed at the top of the support 1. The output end of the electric push rod 23 is bolted to the support plate 24. Telescopic rods 25 are provided on both the front and rear sides of the electric push rod 23, and the telescopic ends of the telescopic rods 25 are bolted to the support plate 24. Connecting plates 26 are fixedly connected to the bottom sides of both ends of the support plate 24, and T-shaped sliders 27 are fixedly connected to the bottom sides of the connecting plates 26. Through the electric push rod 23 and the telescopic rods 25, the height of the heating roller can be adjusted according to the film thickness. During adjustment, the T-shaped slider 27 slides within the through groove 21, and both ends of the support plate 24 slide within the sliding grooves 22, which improves the stability of the heating roller 28 during adjustment.

[0028] like Figure 3 and Figure 4As shown, a heating roller 28 is rotatably connected between two T-shaped sliders 27 via bearings. One end of the heating roller 28 passes through one of the T-shaped sliders 27. A heating cavity 283 is formed in the side wall of the heating roller 28. A first air-collecting hollow plate 282 is provided at one end of the heating roller 28, and a second air-collecting hollow plate 284 is provided at the other end of the heating roller 28. A hollow tube 281 is fixedly connected to the middle of the heating roller 28. One end of the hollow tube 281 is connected to the first air-collecting hollow plate 282, and the other end of the hollow tube 281 passes through the second air-collecting hollow plate 284. The first air-collecting hollow plate 282 and the second air-collecting hollow plate 284 are hollowed out on all sides. Both the first air-collecting hollow plate 282 and the second air-collecting hollow plate 284 are connected to the heating cavity 283. Exhaust holes 285 are formed at both ends of the second air-collecting hollow plate 284. The exhaust port 285 is connected to the outside. A hot air blower 287 is installed at one end of the middle top of the bracket 1. A connecting pipe 286 is provided at the air outlet of the hot air blower 287. The connecting pipe 286 is connected to the hollow tube 281 through a bearing. A pressing roller 29 is rotatably connected to the lower middle part of the bracket 1. The pressing roller 29 is located directly below the heating roller 28. A heating chamber 283 is opened in the heating roller 28. When the hot air blown out by the hot air blower 287 enters the hollow tube 281, it enters the heating chamber 283 through the air collecting hollow plate 282, so that the heating roller 28 is heated. This can smooth the film that is transmitted, and the heat is evenly distributed, so that a consistent flatness effect is achieved in the width of the film. Moreover, due to the temperature and pressure of the heating roller 28, the heating roller 28 can achieve the effect of film flatness in a shorter time, and the flatness efficiency is better.

[0029] This utility model provides a high-barrier film composite flattening device. The specific working principle is as follows: The film is passed through the guide roller 11 and the pressing roller 29 in sequence. When flattening the film, the electric push rod 23 is activated, which causes the support plate 24 to drive the heating roller 28 to move down. During the movement, the T-shaped slider 27 slides in the groove 21, and the two ends of the support plate 24 slide in the sliding groove 22 until the heating roller 28 contacts the film. At the same time, the hot air is blown into the connecting pipe 286 by the hot air blower 287, and then into the hollow pipe 281, and collected in the first air collecting hollow plate 282. Through the hollow design around the perimeter, the hot air is blown into the heating chamber 283, and then collected again by the second air collecting hollow plate 284 until it is discharged from the exhaust hole 285. This makes the heat evenly distributed, so as to achieve a consistent flattening effect across the width of the film. Moreover, due to the temperature and pressure of the heating roller 28, the heating roller 28 can achieve the film flattening effect in a short time.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
