Description

Technical Field

[0001] The present application relates to the technical field of packaging film cooling, and in particular to a cooling device for packaging film stretching. Background Art

[0002] Packaging film mainly refers to the film used for packaging articles, usually including polyethylene packaging film, biaxially oriented polyester, BOPP film and CPP film, etc., which are mainly used for the packaging of food, medicine and textiles. In the production process of packaging film, transverse stretching is an indispensable process, and a cooling device is required when stretching the thermally formed packaging film.

[0003] For example, the patent with publication number CN214934634U specifically discloses a cooling device for packaging film, including a frame, a cooling pipe, a mounting frame, a smoothing roller and a driving mechanism. Thus, by setting two smoothing rollers that can rotate synchronously in opposite directions, when the packaging film passes through the cooling pipe and the two smoothing rollers, the two rotating smoothing rollers can provide a certain force on both sides of the packaging film, so that the two smoothing rollers can stretch and smooth the packaging film, effectively reducing the risk of wrinkles on the packaging film.

[0004] When the above patent is in use, when the packaging film passes through several tension rollers and moves under the scraper, the lower end of the scraper can contact the packaging film and scrape and clean the surface of the packaging film. However, when the packaging film moves under the scraper, only one side of the packaging film can be cleaned, while the side of the packaging film away from the scraper cannot be cleaned and is attached with dust. In addition, since the packaging film is often used for packaging food, medicine and textiles, dust can easily make the packaging film seal loose, affecting the normal use of the packaging film. Therefore, it is necessary to design a cooling device for stretching the packaging film to solve the above problems.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] like Figure 1-Figure 2 As shown, the present application provides a cooling device for stretching packaging film, comprising a frame 1, a top plate 103 is fixedly mounted on the frame 1, and four groups of support rods 101 are fixedly mounted on the top plate 103, and a tensioning roller 102 is rotatably connected between two groups of support rods 101, and the tensioning roller 102 is used for packaging film to be wound in sequence, so as to be suitable for making the packaging film in a tight state;

[0025] Four sets of universal wheels 104 are fixedly mounted on a side of the frame 1 away from the top plate 103, and the universal wheels 104 are suitable for moving the frame 1;

[0026] A cooling mechanism 3 is installed on the frame 1. The cooling mechanism 3 includes two groups of support plates 303 fixedly installed on the frame 1. A cooling pipe 304 is rotatably connected between the two groups of support plates 303. The cooling pipe 304 is arranged in a tapered shape from the middle to the two ends to improve the guiding ability of the packaging film, so that the packaging film can automatically stretch to both sides when passing through the cooling pipe 304.

[0027] One end of the cooling tube 304 is provided with a water inlet pipe 305, and the water inlet pipe 305 is suitable for conveying water into the cooling tube 304. At the same time, one end of the cooling tube 304 away from the water inlet pipe 305 is provided with a drain pipe 306, and the drain pipe 306 is suitable for draining the water in the cooling tube 304, so as to replace the water in the cooling tube 304, so that the film can pass through the upper end of the outer wall of the cooling tube 304, so as to achieve cooling treatment of the film.

[0028] In order to remove wrinkles from the packaging film passing through the surface of the water inlet pipe 305, as Figure 2 As shown, a mounting frame 301 is fixedly mounted on the top plate 103, and two groups of smoothing rollers 302 are rotatably connected between the inner walls of the mounting frame 301. The smoothing rollers 302 have bristles, and two groups of motors (not shown in the figure) are fixedly mounted on the mounting frame 301. The output end of the motor is fixedly connected to one end of the smoothing roller 302, so as to drive the two groups of smoothing rollers 302 to rotate synchronously in opposite directions, so as to stretch the film toward both sides.

[0029] In order to solve the problem that the scraper can only clean one side of the packaging film, Figure 2-Figure 3 As shown, a cleaning mechanism 2 is installed on a side of the top plate 103 close to the tensioning roller 102, and the cleaning mechanism 2 includes a first concave frame 201 fixedly installed on a side of the top plate 103 close to the tensioning roller 102, and a second concave frame (not shown in the figure) is fixedly installed on a side of the first concave frame 201 away from the top plate 103, and the second concave frame is located on one side of the first concave frame 201;

[0030] Both sides of the first concave frame 201 and the second concave frame are provided with a moving groove 202, and a spring 203 is fixedly installed in the moving groove 202, and a collar 204 is fixedly installed at one end of the spring 203, and a cleaning brush 206 is rotatably connected between the two groups of collars 204, and the packaging film is suitable for passing between the two groups of cleaning brushes 206 to clean the upper and lower surfaces of the packaging film. At the same time, the cleaning brush 206 is suitable for being closely attached to the packaging film under the action of the spring 203, and is suitable for scraping and cleaning packaging films of different thicknesses;

[0031] At the same time, a duct 208 is fixedly installed on one side of the top plate 103 near the tensioning roller 102, and a fan is provided in the duct 208. A cover 207 is fixedly installed on one end of the duct 208 near the cleaning brush 206, and the cover 207 has an air suction port, which faces the packaging film.

[0032] When the packaging film passes through the tensioning rollers 102 and moves between the two groups of cleaning brushes 206, a certain traction force is exerted on one end of the packaging film, so that the packaging film passes between the two groups of cleaning brushes 206, which drives the two groups of cleaning brushes 206 to rotate, thereby scraping and cleaning the surface of the packaging film. At the same time, the fan is started to provide a certain suction force in the air duct 208, so that the dust scraped off by the cleaning brush 206 at the upper end can be sucked, and the dust scraped off by the cleaning brush 206 at the lower end on the surface of the packaging film falls by its own gravity.

[0033] When the packaging film moves from between the two sets of cleaning brushes 206 to the upper end of the cooling tube 304, the cold water in the cooling tube 304 cools the packaging film. At this time, the two smoothing rollers 302 are respectively in contact with the packaging film. Then, the two sets of motors drive the corresponding smoothing rollers 302 to rotate, so that the packaging film stretches toward both sides. Then, the packaging film can be rolled up.

[0034] In summary: through the coordinated use of the frame 1, the tensioning roller 102, the first concave frame 201, the movable groove 202, the spring 203, the ring 204, the rotating rod 205, the cleaning brush 206, the cover 207 and the air duct 208, the surface of the packaging film can be scraped and cleaned, and the dust scraped off by the cleaning brush 206 can be sucked out.

[0035] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
