Description

Technical Field

[0001] This utility model relates to the field of packaging film processing technology, and in particular to a dust removal device for packaging film production and winding. Background Technology

[0002] PET packaging film is a high-performance plastic film based on polyethylene terephthalate (PET), possessing excellent transparency, mechanical strength, and dimensional stability. This film not only exhibits excellent temperature resistance (-70℃ to 150℃) and chemical stability but also boasts good moisture-proof, oxygen-barrier, and UV-resistant properties, effectively protecting the contents of the packaged goods. Its smooth and flat surface is suitable for high-speed printing and lamination, and it can be manufactured into single-layer or multi-layer composite structures to meet diverse packaging needs. PET packaging film is widely used in the packaging of food, pharmaceuticals, and electronics industries. During the production and winding process of PET packaging film, dust and impurities on the film can easily affect the winding process and subsequently impact its use; therefore, solutions have been proposed in existing technologies.

[0003] For example, Chinese Patent Publication No. CN217599947U discloses a dust removal device for PET packaging film production and winding, comprising a box body. The left side of the box body has a feed inlet, and the front of the box body has a protective door hinged to it. Air blowing boxes are fixedly embedded in the upper and bottom surfaces of the box body, and each of the two air blowing boxes contains a blower fan. The box body also contains two guide rollers and a winding roller, with the winding roller located to the right of the two guide rollers. An exhaust box is fixedly embedded in the back of the box body, and an exhaust fan is installed inside the exhaust box. This dust removal device for PET packaging film production and winding, by using two blower fans, can blow away debris and dust from the surface of the PET packaging film during production and winding, preventing debris and dust from adhering to the outer surface of the PET packaging film.

[0004] The aforementioned application uses multiple fans to blow away dust and impurities from the surface of the packaging film. However, this process can only remove loosely attached dust from the surface. It is difficult to effectively remove particles that are electrostatically adsorbed or highly adhesive, resulting in an overall poor dust removal effect. Furthermore, the high-speed airflow can easily spread the blown-away dust into the surrounding environment, which can cause secondary pollution to the packaging film or internal pollution to the equipment.

[0005] Therefore, it is necessary to provide a dust removal device for winding packaging film production to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a dust removal device for winding packaging film production, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: A dust removal device for winding packaging film production includes a housing, inside which a dust removal assembly is provided. The dust removal assembly includes two symmetrically distributed dust removal cylinders disposed inside the housing. Each dust removal cylinder has an inner cavity, and its side surface has multiple circular protrusions of different sizes. The side surface of each circular protrusion has multiple suction holes communicating with the inner cavity. The outside of the housing is provided with an adjustment assembly that drives the two dust removal cylinders to rotate synchronously.

[0008] As a further embodiment of this utility model, both ends of the dust collector are fixed with tube shafts arranged coaxially with the dust collector, and a U-shaped tube is provided on the outside of the outer shell. The two ends of the U-shaped tube are respectively rotatably connected to two tube shafts on the same side and communicate with the inner cavity. A suction tube is connected to the U-shaped tube.

[0009] As a further embodiment of this utility model, the adjustment assembly includes a rack plate, two tube shafts on the other side of the two dust collectors are fixed with gears, an electric push rod is fixed on the outer wall of the outer shell, and the rack plate is fixed to the output end of the electric push rod and meshes with the two gears.

[0010] As a further embodiment of this utility model, a sliding sleeve is fixed on the outer side wall of the outer shell, and the end of the rack plate away from the electric push rod is slidably connected to the sliding sleeve.

[0011] As a further embodiment of this utility model, the plurality of suction holes are equidistantly distributed along the length of the dust removal cylinder.

[0012] As a further embodiment of this utility model, two guide rollers symmetrically distributed are provided at both ends of the outer shell.

[0013] As a further embodiment of this utility model, a groove is provided on the side of the outer shell, and both ends of the guide roller are rotatably connected to a shaft arranged coaxially with the guide roller and inserted into the groove. A spring is provided in the groove, and both ends of the spring are fixed to the side of the groove end and the side of the shaft, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When cleaning packaging films of different thicknesses, the two dust collection cylinders are adjusted by rotating the components synchronously. The different sizes of round protrusions are adjusted to face the packaging film, thereby conveniently adjusting the distance between the suction hole and the packaging film. This makes it suitable for suction dust removal of packaging films of different thicknesses. The adsorption force can be optimized for packaging films of different thicknesses, avoiding incomplete dust removal due to improper distance or film deformation caused by excessive suction force. This effectively improves the applicability of the overall device and enhances its versatility. At the same time, by reasonably controlling the distance between the suction hole and the film, it is ensured that the negative pressure airflow evenly covers the film surface, effectively adsorbing small particles and impurities, and improving the overall dust removal effect.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Please see Figure 1-6This utility model provides a dust removal device for winding packaging film, including a housing 3. A dust removal component 1 is disposed inside the housing 3. The dust removal component 1 includes two symmetrically distributed dust removal cylinders 101 disposed inside the housing 3. Each dust removal cylinder 101 has an inner cavity 106. Multiple circular protrusions 102 of different sizes are provided on the side of each dust removal cylinder 101. Multiple suction holes 103 communicating with the inner cavity 106 are provided on the side of each circular protrusion 102. The multiple suction holes 103 extend along the dust removal cylinder 101. The length of the two dust collector cylinders 101 is evenly distributed. An adjustment assembly 2 is provided on the outside of the outer casing 3 to drive the two dust collector cylinders 101 to rotate synchronously. During use, the packaging film passes through the inside of the outer casing 3 and is pulled and wound by a winding roller. As the packaging film passes through the inside of the outer casing 3, it passes between the two dust collector cylinders 101. The inner cavity 106 of the dust collector cylinder 101 has a negative pressure. The round protrusion 102 at the bottom of the dust collector cylinder 101 faces the packaging film, thereby... The suction holes 103 on the round protrusions 102 on the packaging film remove dust particles from both sides, thus thoroughly cleaning the sides of the packaging film and effectively improving its cleanliness. When cleaning packaging films of different thicknesses, the two dust collection cylinders 101 are rotated synchronously to adjust the different sizes of the round protrusions 102 toward the packaging film, thereby conveniently adjusting the distance between the suction holes 103 and the packaging film. This allows for dust removal treatment of packaging films of different thicknesses, optimizing the adsorption force for packaging films of different thicknesses and avoiding incomplete dust removal or film deformation due to excessive suction caused by improper distance. This effectively improves the applicability of the overall device and enhances its versatility. At the same time, by reasonably controlling the distance between the suction holes 103 and the film, it ensures that the negative pressure airflow evenly covers the film surface, effectively adsorbing small particles and impurities and improving the overall dust removal effect. Dust in other locations inside the outer casing 3 can also be removed through the suction holes 103 located on other positions on the dust collection cylinders 101, further improving the dust removal effect.

[0027] Further as Figure 2 As shown, it is worth noting that both ends of the dust collection cylinder 101 are fixed with tube shafts 104 arranged coaxially with the dust collection cylinder 101. A U-shaped tube 105 is provided on the outside of the outer shell 3. The two ends of the U-shaped tube 105 are rotatably connected to the two tube shafts 104 on the same side and are connected to the inner cavity 106. A suction tube 107 is connected to the U-shaped tube 105. In specific operation, the suction tube 107 is connected to the input end of the vacuum cleaner, so that the inner cavity 106 inside the two dust collection cylinders 101 has a suction negative pressure simultaneously through the suction tube 107 and the U-shaped tube 105, thereby realizing the suction hole 103 to suck and remove dust particles on both sides of the packaging film.

[0028] Further as Figure 1 and Figure 3As shown, it is worth noting that the adjustment assembly 2 includes a rack plate 201, and two tube shafts 104 on the other side of the two dust collectors 101 are fixed with gears 202. An electric push rod 204 is fixed on the outer wall of the outer casing 3. The rack plate 201 is fixed to the output end of the electric push rod 204 and is meshed with the two gears 202. In specific operation, the output end of the electric push rod 204 drives the rack plate 201 to move, thereby driving the two tube shafts 104 to rotate synchronously and adjust through the meshing of the rack plate 201 and the gears 202. This allows the same-sized round protrusions 102 on the two dust collectors 101 to rotate synchronously and switch their orientation towards the two sides of the packaging film.

[0029] Further as Figure 3 As shown, it is worth noting that a sliding sleeve 203 is fixed on the outer wall of the outer casing 3, and the end of the rack plate 201 away from the electric push rod 204 is slidably connected to the sliding sleeve 203. In actual operation, the sliding sleeve 203 guides and limits the movement of the rack plate 201, thereby improving the stability of the movement adjustment of the rack plate 201.

[0030] This solution has the following working process: The packaging film passes through the inside of the outer shell 3 and is pulled and wound up by the winding roller. When the packaging film passes through the inside of the outer shell 3, it passes between two dust collection cylinders 101. The inner cavity 106 of the dust collection cylinder 101 has negative pressure. The round protrusion 102 at the bottom of the dust collection cylinder 101 faces the packaging film. Thus, the dust particles on both sides of the packaging film are sucked and removed through the suction hole 103 on the round protrusion 102 on the side of the dust collection cylinder 101 facing the packaging film, thereby thoroughly cleaning the side of the packaging film. When cleaning packaging films of different thicknesses, the output end of the electric push rod 204 drives the rack plate 201 to move. Thus, the rack plate 201 and the gear 202 mesh and drive the two dust collection cylinders 101 to rotate synchronously and adjust. This realizes the switching adjustment of the different sizes of round protrusions 102 on the dust collection cylinder 101 facing the packaging film, thereby realizing convenient adjustment of the distance between the suction hole 103 and the packaging film, so as to be suitable for suction dust removal treatment of packaging films of different thicknesses.

[0031] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that two symmetrically distributed guide rollers 4 are provided at both ends of the outer shell 3. In actual operation, the guide rollers 4 guide and limit the packaging film, and guide and limit the conveying of the packaging film.

[0032] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that a groove 6 is provided on the side of the outer shell 3. Both ends of the guide roller 4 are rotatably connected to a shaft 5 arranged coaxially with the guide roller 4 and inserted into the groove 6. A spring 7 is provided in the groove 6, and the two ends of the spring 7 are fixed to the side of the groove 6 and the side of the shaft 5, respectively. In actual operation, the spring 7 enables the guide roller 4 to have a certain degree of self-adjustment, making the guide roller 4 suitable for guiding packaging films of different thicknesses.

[0033] In summary: By adjusting the synchronous rotation of component 2 to adjust the two dust collection cylinders 101 and adjusting the different sized round protrusions 102 toward the packaging film, the distance between the suction hole 103 and the packaging film can be easily adjusted. This allows for dust removal treatment of packaging films of different thicknesses. The adsorption force can be optimized for packaging films of different thicknesses, avoiding incomplete dust removal or film deformation caused by excessive suction due to improper distance. This effectively improves the applicability of the overall device and enhances its versatility. At the same time, by reasonably controlling the distance between the suction hole 103 and the film, it is ensured that the negative pressure airflow evenly covers the film surface, effectively adsorbing small particles and impurities, and improving the overall dust removal effect.

[0034] The electric linear actuator 204 can be purchased from the market. The electric linear actuator 204 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
