Abstract
Description
Technical Field
[0001] The utility model relates to a film production device, in particular to a film anti-wrinkle winding device. Background Art
[0002] Existing agricultural film production devices generally first blow out an annular film by a blow molding device, then fold the annular film into a double-layer film by a guiding device, and finally wind it by a traction device and a winding device. However, there is a conveying distance for the film from being blown out and conveyed until being wound. During this process, the film may be blown by the wind or wrinkled for other reasons, and the wrinkled part cannot return automatically. Therefore, the wrinkled part will be wound by the winding device, which causes the film wound subsequently to be affected by the previous wrinkles when winding around the reel, resulting in the film on this reel being continuously wound in a wrinkled state, greatly affecting the winding effect and thus having a certain impact on the production quality of the film. Content of the Utility Model
[0003] The purpose of the utility model is to provide a film anti-wrinkle winding device that can prevent the film from being wrinkled, make the winding effect better, and improve the production quality of the film.
[0004] To achieve the above purpose, the film anti-wrinkle winding device provided by the utility model includes a cutting device, a traction device, two anti-wrinkle devices, and two winding devices arranged in sequence along the film conveying direction; the traction device provides a traction force to move the film; the cutting device cuts the connected double-layer film into two mutually separated films; the two anti-wrinkle devices are arranged side by side and flatten the edges of the film respectively; the two winding devices are arranged side by side and automatically wind their respective films respectively; the anti-wrinkle device includes a laser detector and a pair of air blowing mechanisms, and the laser detector and the air blowing mechanisms are electrically connected to a control system respectively to detect whether the edges of the film are wrinkled; the two air blowing mechanisms are arranged between the laser detector and the winding device, and the two air blowing mechanisms are respectively arranged on both sides of the surface and the bottom surface of the film to blow flat the edge wrinkles of the film.
[0005] Compared with the prior art, the utility model arranges a cutting device, a traction device, two anti-wrinkle devices, and two winding devices in sequence along the film conveying direction, uses the traction device to provide a forward traction force for the film, and then cuts the connected double-layer film into two mutually separated films by the cutting device; and by arranging an anti-wrinkle device before winding, using the laser detector to detect the film first, and then blowing air on both the upper and lower sides of the edge of the film by the air blowing mechanisms to blow the edge of the film flat before winding, so as to avoid winding the film in a wrinkled state, effectively ensure the winding effect, and improve the production quality of the film.
[0006] Specifically, the cutting device includes two cutting mechanisms, which are symmetrically arranged on both side edges of the film. Each cutting mechanism includes a fixed bracket, a sliding seat, a guiding rod, a guiding wheel, an elastic element and a cutter. The sliding seat is slidably arranged on the fixed bracket. The elastic element is connected between the sliding seat and the fixed bracket. The guiding rod is vertically fixed on the sliding seat. The upper end of the guiding rod penetrates into the double-layer film. The guiding wheel is arranged on one side of the guiding rod facing the edge of the film to rollingly contact the film under the action of the elastic force applied by the elastic element to the sliding seat. The cutter is arranged outside the lower end of the guiding rod to cut the double-layer film into two separable films.
[0007] Specifically, the blowing nozzle of the blowing mechanism is inclined towards the outer edge of the film. This can enable the gas blown out by the blowing nozzle to push the film to extend towards the outer edge, improving the flattening effect of the film.
[0008] Specifically, the anti-wrinkle device further includes a brush shaft and a motor. The brush shaft is arranged between the blowing mechanism and the winding device. The output end of the motor is connected to the brush shaft to drive the brush shaft to rotate, so that the brush shaft sweeps the wrinkled part of the film towards the edge direction.
[0009] Specifically, multiple rows of bristles are spirally arranged on the surfaces of both ends of the brush shaft around the central axis, and the spiral directions of the bristles at both ends of the brush shaft are opposite. The rotation direction on the upper side of the brush shaft is opposite to the conveying direction of the film to sweep the wrinkles of the film on each side towards the edge direction of the film. For some films affected by static electricity and the like, their wrinkle degree is relatively large and the wrinkles are not easily blown flat. Therefore, by arranging the brush shaft, using the frictional resistance generated between the brush shaft and the film, the film can be swept flat by the bristles, thereby further improving the anti-wrinkle effect of the film and ensuring the winding effect of the film.
[0010] Preferably, a transition roller is arranged between the anti-wrinkle device and the traction device. Description of the Drawings

[0015] To describe in detail the technical content, structural features, and achieved effects of the present utility model, the following will be described in detail in conjunction with the implementation modes and with reference to the drawings.
[0016] As Figure 1 shown, the thin film anti-wrinkle winding device 100 of the present utility model includes a cutting device 9, a traction device 6, two anti-wrinkle devices 110, and two winding devices 7 arranged in sequence along the thin film conveying direction; the traction device 6 provides a traction force to move the thin film; the cutting device 9 cuts the connected double-layer thin film 200 into two separated thin films 200; a transition roller 8 is provided between the anti-wrinkle device 110 and the traction device 9. The two anti-wrinkle devices 110 are arranged side by side and flatten the edges of the thin film 200 respectively; the two winding devices 7 are arranged side by side and automatically wind their respective thin films 200 respectively.
[0017] Again, as Figure 1 and Figure 2 shown, the cutting device 9 includes two cutting mechanisms 91, the two cutting mechanisms 91 are symmetrically arranged on both side edges of the thin film, the cutting mechanism 91 includes a fixed bracket 911, a sliding seat 912, a guiding rod 913, a guiding wheel 914, an elastic element 915, and a cutter 916, the sliding seat 912 is slidably arranged on the fixed bracket 911, the elastic element 915 is connected between the sliding seat 912 and the fixed bracket 911, the guiding rod 913 is vertically fixed on the sliding seat 912, the upper end of the guiding rod 913 penetrates into the double-layer structure thin film, the guiding wheel 914 is arranged on the side of the guiding rod 913 facing the thin film edge, so as to rollingly contact the thin film under the action of the elastic force applied by the elastic element 915 to the sliding seat 912, which can not only make the thin film stretch out to prevent wrinkles, but also facilitate the subsequent cutting. The cutter 916 is arranged outside the lower end of the guiding rod 913 to cut the double-layer structure thin film into two separable thin films.
[0018] Please refer to Figure 1 and Figure 3, the film anti-wrinkle winding device 100 further includes an anti-wrinkle device 110. The anti-wrinkle device 110 is disposed before each winding device 7 and is electrically connected to the control system to flatten the edges of the film. Since there is still a certain conveying distance for the double-layer film from being blown out to being wound, during this process, the film may be wrinkled by wind or other reasons. Therefore, by setting the anti-wrinkle device 110, the film can be prevented from being wrinkled before winding, improving the winding effect and ensuring the aesthetics of the wound film and the film during use. Specifically, the anti-wrinkle device 110 includes a laser detector 111 and a pair of air blowing mechanisms 112. The laser detector 111 and the air blowing mechanisms 112 are respectively electrically connected to the control system to detect whether the edges of the film are wrinkled; the two air blowing mechanisms 112 are disposed between the laser detector 111 and the winding device 7. The air blowing mechanism 112 includes an air blowing nozzle 1121 and a pneumatic generating device (not shown in the figure). The air blowing nozzle 1121 is connected to the pneumatic generating device. The two air blowing nozzles 1121 are respectively disposed on both sides of the surface and the bottom surface of the film, and the air blowing nozzle 1121 is inclined towards the outer edge of the film to flatten the wrinkled part of the edge of the film. In this way, the gas blown out by the air blowing nozzle 1121 can push the film to extend towards the outer edge, improving the flattening effect of the film. By first detecting the film with the laser detector 111 and then blowing air on both the upper and lower sides of the edge of the film with the air blowing mechanisms 112, and winding the film after flattening the edge of the film, the film can be prevented from being wound in a wrinkled state, effectively ensuring the winding effect.
[0019] Please refer to again Figure 1 , Figure 3 and Figure 4 , the anti-wrinkle device 110 further includes a brush shaft 113 and a motor 114. The brush shaft 113 is disposed between the air blowing mechanism 112 and the winding device 7. The output end of the motor 114 is connected to the brush shaft 113 to drive the brush shaft 113 to rotate, so that the brush shaft 113 sweeps the wrinkled part of the film towards the edge direction. More specifically, multiple rows of bristles 1131 are spirally provided on the surfaces of both ends of the brush shaft 113 around the central axis, and the spiral directions of the bristles 1131 at both ends of the brush shaft 113 are opposite. The rotation direction on the upper side of the brush shaft 113 is opposite to the conveying direction of the film to sweep the wrinkles on one side of the film towards the edge direction of the film. For some films with electrostatic effects and other influences, their wrinkles are relatively large and the wrinkles are not easily blown flat. Therefore, by setting the brush shaft 113 and using the frictional resistance generated between the brush shaft 113 and the film, the film can be swept flat by the bristles 1131, further improving the anti-wrinkle effect of the film and ensuring the winding effect of the film.
[0020] Combined with the above andFigure 1 , the working principle of the film anti-wrinkle winding device 100 of the present utility model will be described in detail as follows:
[0021] During the transportation of the film 200, the double-layer film 200 passes through the guiding rod 913 and is completely unfolded by the guiding wheel 914 under the action of the elastic element 915. Then, the double-layer film 200 passes downward through the cutting knife 916, and the cutting knife 916 cuts along the folding line on both sides of the double-layer film 200, so that the double-layer film 200 is separated into two independent films 200. The two independent films 200 are respectively transported in different directions after passing through the transition roller 8, and the two films 200 enter the winding device 7 for winding after passing through their respective anti-wrinkle devices 110. During the process of the film 200 passing through the anti-wrinkle device 110, the laser detector 111 will detect the edge of the film 200. If wrinkles are detected at the edge of the film 200, then the control system controls the blowing mechanism 112 to start, and the blowing mechanisms 112 on the upper and lower sides blow the film 200 from the inside to the edge direction at the same time, so that the wrinkled part is blown flat. In addition, after passing through the blowing mechanism 112, the film 200 also passes through the brush shaft 113, and the bristles 1131 on the brush shaft 113 wipe the wrinkled part, so that the wrinkles are swept flat. Finally, the film 200 enters the winding device 7 and is wound by the winding device 7.
[0022] Compared with the prior art, the present utility model is provided with a cutting device 9, a traction device 6, two anti-wrinkle devices 110 and two winding devices 7 in sequence along the transportation direction of the film 200. The traction device 6 provides the forward traction force for the film, and then the cutting device 9 cuts the connected double-layer film 200 into two separated films 200; and by setting the anti-wrinkle device 110 before winding, the laser detector first detects the film 200, and then the blowing mechanism 112 blows air on both the upper and lower sides of the edge of the film 200 to blow the edge of the film 200 flat before winding, so as to avoid winding the film 200 in a wrinkled state, effectively ensuring the winding effect and improving the production quality of the film.
[0023] The structures of the winding device 7 involved in the film anti-wrinkle winding device 100 of the present utility model are well known to those of ordinary skill in the art and will not be described in detail herein.
[0024] The above-disclosed are only the preferred examples of the present utility model. Of course, the scope of rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present utility model still fall within the scope covered by the present utility model.
