Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging film processing technology, specifically a plastic packaging film drying device. Background Technology
[0002] Packaging film is mainly made of several different grades of resin mixed and extruded. It has puncture resistance, high strength and high performance. It is used to wrap goods stacked on pallets, making the packaged goods more stable and neat, and has a strong waterproof effect. It is widely used. After production, plastic packaging film is usually transported and sold in stacks or rolls. Because some water stains remain on the plastic packaging film during production, the plastic packaging film will stick together during normal winding and cannot be separated, and may even tear, affecting the use effect. Traditional plastic packaging film drying equipment cannot wind up the dried packaging film, so manual winding is required after drying, which is very wasteful of manpower.
[0003] A search revealed a patent with publication number CN221781157U, which discloses a plastic packaging film drying device. The device includes a worktable and supporting legs. The supporting legs are symmetrically fixed to the bottom of the worktable. A film-laying mechanism for driving the plastic packaging film roll is fixed to the top of the worktable. A winding mechanism for winding the plastic packaging film is fixed to the side of the top of the worktable away from the film-laying mechanism. A drying mechanism for drying the plastic packaging film is fixed to the top of the worktable. A moisture-absorbing mechanism for removing surface moisture from the plastic packaging film is fixed to the top of the worktable between the drying mechanism and the film-laying mechanism. This invention can effectively dry the surface moisture of the plastic packaging film. The moisture-absorbing mechanism prevents deformation and damage to the plastic packaging film caused by excessive heating and dehumidification when the film is severely damp. It also allows for the winding of the dried plastic packaging film, saving manpower and improving production efficiency.
[0004] In the aforementioned prior art, the moisture-absorbing mechanism relies on absorbent cotton to remove moisture from the surface of the packaging film. However, it requires manual replacement of the dry absorbent cotton to ensure the moisture-absorbing performance. This operation is too cumbersome, and operators need to frequently stop the machine to replace the absorbent cotton. This not only increases the labor intensity but also causes production interruptions, affecting the continuity and stability of production and reducing overall production efficiency.

[0027] Example
[0028] Please see Figures 1-5 This utility model provides a technical solution:
[0029] A plastic packaging film drying device includes a processing table 1, which is made entirely of stainless steel. Support legs are welded at the four corners of the bottom, and anti-slip pads are installed on the bottom of the support legs to enhance the stability of the device during operation. A drying chamber 2 is fixed to the processing table 1 by bolts. The drying chamber 2 has a cuboid structure, and a sealing door 3 is connected to its front by a hinge. The sealing door 3 is made of double-layer tempered glass, which not only facilitates the operator to observe the working conditions inside the drying chamber 2, but also provides a good heat preservation effect. An exhaust vent 4 is provided on the outer wall of the sealing door 3. A dustproof net is installed inside the exhaust vent 4 to prevent external dust from entering the drying chamber 2. Openings 6 are provided on both sides of the drying chamber 2. The openings 6 on both sides of the drying chamber 2 are distributed vertically opposite each other. This distribution can accommodate the packaging film entering the drying chamber 2 at an inclined angle, increasing the travel of the packaging film in the drying chamber 2, thereby improving the drying effect. Guide rollers 5 are also symmetrically arranged on both sides of the top of the processing table 1. The guide rollers 5 are fixed on the processing table 1 by a bracket. The outer surface of the guide rollers 5 is covered with a rubber layer to avoid scratching the packaging film, and at the same time, it can increase the friction between the guide rollers and the packaging film to ensure the smooth transport of the packaging film.
[0030] The drying chamber 2 is equipped with a first partition 9, which divides the interior of the drying chamber 2 into two spaces. On one side of the first partition 9, there are evenly distributed moisture-absorbing rollers 7. The evenly distributed moisture-absorbing rollers 7 are arranged in two symmetrical rows on the first partition 9, and the packaging film extends in a Z-shape on the two rows of moisture-absorbing rollers 7. This arrangement allows both sides of the packaging film to fully contact the moisture-absorbing rollers 7, improving the moisture absorption effect. The moisture-absorbing rollers 7 include a positioning rod 14 inserted and rotatably mounted on the first partition 9. The positioning rod 14 is a cavity structure and is connected to the space on the other side of the first partition 9. A rotating frame 15 is rotatably mounted on the positioning rod 14. Moisture-absorbing cotton 16 is evenly distributed on the rotating frame 15. Several exhaust ports 17 are also opened on the outer wall of the positioning rod 14, and the exhaust ports 17 are evenly distributed.
[0031] A heating lamp assembly 8, consisting of multiple infrared heating lamps, is installed on the upper part of the inner wall of the drying oven 2. These lamps are fixed to the inner wall of the drying oven 2 by brackets, enabling uniform heating of the interior. A fan 11 is installed on the other side of the processing table 1, connected to the interior of the processing table 1 via a pipe. The fan 11 is a centrifugal fan, characterized by its large air volume and high air pressure. A second partition 10 is also installed on the other side of the processing table 1, forming a heating chamber between the second partition 10 and the first partition 9. A curved pipe 13 is installed on the second partition 10, its shape resembling a loop. This loop-shaped curved pipe 13 prolongs the air flow time within the heating chamber, ensuring thorough heating. A connection port 12 is provided at the end of the curved pipe 13 on the second partition 10, connecting to the air outlet of the fan 11.
[0032] When using this plastic packaging film drying device, firstly, one end of the packaging film is passed sequentially through the guide roller 5 on one side of the top of the processing table 1 and the opening 6 on one side of the drying chamber 2. Then, the packaging film is passed through the two rows of moisture-absorbing rollers 7 in a Z-shaped extension direction, and then exits from the opening 6 on the other side of the drying chamber 2, passing around the guide roller 5 on the other side of the top of the processing table 1. Finally, it is connected to the winding mechanism. When the device is started, the packaging film begins to move under the drive of the winding mechanism. When the packaging film passes through the moisture-absorbing rollers 7, the moisture-absorbing cotton 16 on the rotating frame 15 contacts the surface of the packaging film and absorbs some of the moisture on the packaging film. At the same time, the fan 11 starts to work, supplying air into the processing table 1. The air enters the curved pipe 13 through the connection port 12. Since the heating lamp group 8 in the drying chamber 2 continuously heats the internal space, the temperature of the heating chamber between the second partition 10 and the first partition 9 rises. When air flows through the curved pipe 13, it fully absorbs the heat in the heating chamber, achieving a good heating effect. The heated air enters the space on the other side of the first partition 9 and is then blown out through the exhaust port 17 on the positioning rod 14. The blown hot air blows onto the packaging film to further dry it, and onto the moisture-absorbing cotton 16 that is rotating on the positioning rod 14. Since the rotating frame 15 rotates with the movement of the packaging film, the moisture-absorbing cotton 16 can be evenly blown by the hot air, thereby achieving self-drying of the moisture-absorbing cotton 16, ensuring its continuous moisture absorption performance, and extending the replacement period. In the whole process, the heating effect of the heating lamp group 8 is further improved, while the guide roller 5 ensures the stability of the packaging film during the conveying process and avoids the packaging film from shifting or wrinkling.
[0033] In this solution, the self-drying function of the absorbent cotton 16 is realized through the linkage of the fan 11, the curved pipe 13, the exhaust port 17 on the positioning rod 14, etc. Compared with the existing technology that requires manual replacement of absorbent cotton, it reduces the labor intensity of operators, avoids production interruption caused by replacing absorbent cotton, ensures the continuity and stability of production, and improves the overall production efficiency.
[0034] The use of a curved pipe 13 extends the air flow time, allowing the air to be fully heated. The heated air can not only dry the packaging film, but also effectively self-dry the absorbent cotton 16, ensuring the absorbent cotton 16's moisture absorption performance. This improves the moisture absorption and drying effect on the packaging film, ensuring that the packaging film will not stick or tear due to residual moisture when it is rolled up, thus guaranteeing the packaging film's performance.
[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
