AI Technical Summary
The existing plastic film guide devices are prone to adhesion of dust and impurities in the dry air in summer, resulting in impurities being squeezed onto the film when the guide roller is offset, reducing the film quality, and lacking cleaning devices, making them less practical.
A plastic film guide device including a bracket, a guide correction device, a guide roller, a motor, a cleaning brush and a dust barrier device is designed. The cleaning brush is driven by the motor to rub against the guide roller to clean the dust and impurities on the surface, and use the dust barrier to prevent the cleaned dust from adhering again.
The dust and impurities on the surface of the guide roller are effectively removed, preventing them from being squeezed onto the film when the guide is offset, improving the quality of the film and the practicality of the guide device.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic film guiding devices, in particular to a plastic film guiding device. Background Technique
[0002] As is well known, with the development of the economy and the continuous improvement of the scientific and technological level, the plastic film industry in China has developed faster and faster, and plastic films are used more and more in daily life. The production of films generally adopts the blow molding process of flat extrusion and upward blowing. In this molding process, the raw materials are first melted and plasticized in an extruder, and the molten raw materials are extruded and blown by a film blowing device to form a film tube. The film tube is then cooled by an air ring, and the cooled film tube is flattened by a chevron plate to form a bonded film. Finally, the film is pulled to a winding roll by a traction roll to form a film product.
[0003] In some small factories, it is impossible to achieve a dust-free environment in the factory. Since the production of plastic films requires the use of equipment such as film blowing, the air flow in the factory is relatively high. When the weather is dry in summer, dust or other impurities in the air will adhere to the guiding rollers of the plastic film guiding device. When the guiding rollers shift and drive the plastic film to return to the correct position, a strong extrusion force will be generated. Therefore, the dust on the guiding rollers is easily squeezed onto the plastic film, thereby reducing the quality of the plastic film. And this device does not have a device for cleaning dust and other impurities on the guiding rollers, so its practicability is not very good and there is still room for improvement.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Please refer to Figures 1-6 , a plastic film guiding device of the present utility model includes a support 1. A guiding and correcting device 2 is arranged in the middle of the support 1. A guiding roller 3 is rotatably connected in the middle of the guiding and correcting device 2 for guiding the skewed or offset plastic film. Several support plates are arranged in the middle of the support 1. A motor 4 is installed in the middle of the front support plate. The rear part of the motor 4 is rotatably connected with a cleaning brush 5 through a rotating shaft for cleaning the guiding roller 3. The rear part of the cleaning brush 5 is rotatably connected with the rear support plate through a rotating shaft. Several mounting holes are arranged inside the support 1, and several connecting rods are installed in all of them. The other ends of several connecting rods are movably connected with a dust shielding device for shielding the dust after cleaning.
[0026] The upper end face of the cleaning brush 5 is in contact with the lower end face of the guiding roller 3, which is convenient for the motor 4 to drive the cleaning brush 5 to rotate and generate friction with the guiding roller 3 to clean the dust on the surface. The cleaning brush 5 is made of flexible materials such as nylon, polypropylene, polyester or polyethylene, etc., which is convenient for deforming according to the deviation of the guiding roller 3 without damaging itself.
[0027] All of the several mounting holes are threaded holes 6, and all of the several connecting rods are bolts 7, and they are all threadedly connected with the corresponding threaded holes 6.
[0028] The dust shielding device includes a base 8. Another threaded hole 6 is arranged around the base 8, and they are all threadedly connected with the corresponding bolts 7. Through the threaded connection mode of the bolt 7 and the threaded hole 6, the base 8 is installed on the support 1. A dust shield 9 is arranged on one side of the base 8. The dust shield 9 is arranged in an inclined shape. The dust shield 9 is made of deformable nylon material. When the guiding roller 3 swings, it pushes the dust shield 9 to deform without damaging itself.
[0029] One end face of the dust shield 9 is in contact with the end face of the guide roller 3 to prevent the dust after cleaning from passing through between the two. There is a gap between the dust shield 9 and the cleaning brush 5 to prevent the cleaning brush 5 from colliding with the dust shield 9 during rotation.
[0030] A film discharging device 10 is provided on the left part of the bracket 1, a deviation detection device 12 is provided on the right part of the bracket, and a conveying roller 11 is provided on the right part of the bracket 1.
[0031] In summary, when the plastic film guiding device is in use, when dust and other impurities in the air adhere to the surface of the guide roller 3 and reach a certain amount, in order to prevent the impurities on the surface from adhering to the film during the extrusion between the guide roller 3 and the film when guiding and straightening the film, the motor 4 can be started. During the rotation of the motor 4, the cleaning brush 5 is driven to rotate, moving relative to the swinging guide roller 3 and generating friction to scrape off the impurities on the surface. The scraped-off dust and other impurities impact on the side wall of the dust shield 9 under the action of centrifugal force and are blocked and fall downward. The staff can place a collection box below to collect the fallen dust and other impurities, and then turn off the motor 4 after cleaning.
[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
