Description

Technical Field

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

[0002] In the processing of plastic packaging films, curing refers to the key process step of allowing the adhesive to fully react and the solvent to fully evaporate under specific temperature and humidity conditions for a certain period of time.

[0003] However, in the existing technology, if the space utilization rate is low during the curing process of plastic packaging film, it means that the volume of the curing equipment or curing area is not fully utilized, resulting in a limited number of plastic packaging films that can be processed in the same time, thereby reducing the overall production capacity. In addition, low space utilization rate also causes uneven distribution of curing temperature and humidity, resulting in some packaging films being under-cured or over-cured, affecting the consistency and stability of product quality. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art where low space utilization means that the volume of the curing equipment or curing area is not fully utilized, resulting in a limited number of plastic packaging films that can be processed in the same amount of time, thereby reducing the overall production capacity. Therefore, this invention proposes a curing device for processing plastic packaging films.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a curing device for processing plastic packaging film, including a curing box, an installation opening on the top of the curing box, a filter box installed inside the installation opening, and a movable mechanism installed inside the curing box;

[0006] The mechanism includes two side plates and a first curing rack. Support plates are fixedly connected to both sides of the top of the first curing rack. A second movable rod is rotatably connected to the top of the support plate. A first movable rod is provided on one side of the second movable rod. A second curing rack is rotatably connected to one end of the second movable rod. The bottom end of the second curing rack is rotatably connected to the first movable rod. A sliding groove is provided on the surface of the side plate. A movable block is slidably connected to the inside of the sliding groove. One end of the movable block is rotatably connected to the first movable rod. A connecting frame is fixedly connected to one side of the bottom of the first curing rack.

[0007] Preferably, the side plate is fixedly connected to the inner wall of the cylinder.

[0008] Preferably, both the second curing rack and the first curing rack have openings on their surfaces, with the second curing rack located above the first curing rack.

[0009] Preferably, a cylinder is installed on one side of the curing box, and the cylinder output end is fixedly connected to the connecting frame.

[0010] Preferably, air outlets are provided on both sides of the filter box, and a filter element is fixedly installed at the bottom of the inner cavity of the filter box.

[0011] Preferably, the curing box has two hinged doors on its side wall.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the connecting frame is driven by a cylinder to move linearly, realizing the linkage of the first curing frame and the second curing frame to push out and release. The second curing frame is gradually raised under the guidance of the moving block along the inclined slide, so that it is higher than the initial level, providing sufficient vertical space to facilitate the operator to take out the cured plastic packaging film smoothly. At the same time, the lifting design effectively avoids accidental collision and interference during the film taking process, ensuring the safety and smoothness of operation. The overall linkage and lifting mechanism not only improves the convenience and safety of film taking, but also optimizes the transfer and material changing process after curing, improving production efficiency and operating experience.

[0014] 2. In this utility model, the filter box plays a dual crucial role in exhaust and purification during the curing process, effectively ensuring smooth airflow and stable pressure inside the curing box. Through a rationally designed air outlet, exhaust gas is smoothly discharged, avoiding airflow blockage and maintaining system balance. The multi-layer filter element filters harmful substances and fine particles, preventing direct emission of pollutants and significantly reducing the risk of environmental pollution. Its high-efficiency and environmentally friendly materials ensure filtration accuracy and durability, meeting the needs of continuous operation. The location inside the installation port allows maintenance personnel to quickly disassemble and replace the filter element, improving maintenance efficiency, reducing equipment downtime, and ensuring production continuity. The overall design effectively improves the safety and environmental performance of the curing process and the reliability of equipment operation. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4 As shown, this utility model provides a curing device for processing plastic packaging film, including a curing box 1, an installation port 11 is provided on the top of the curing box 1, a filter box 2 is installed inside the installation port 11, and a movable mechanism 4 is installed inside the curing box 1.

[0023] The active mechanism 4 includes two side plates 45 and a first curing rack 43. Support plates 49 are fixedly connected to both sides of the top of the first curing rack 43. A second movable rod 48 is rotatably connected to the top of the support plate 49. A first movable rod 46 is provided on one side of the second movable rod 48. A second curing rack 44 is rotatably connected to one end of the second movable rod 48. The bottom end of the second curing rack 44 is rotatably connected to the first movable rod 46. A sliding groove 451 is provided on the surface of the side plate 45. A moving block 47 is slidably connected to the inside of the sliding groove 451. One end of the moving block 47 is rotatably connected to the first movable rod 46. A connecting frame 42 is fixedly connected to one side of the bottom of the first curing rack 43.

[0024] The specific settings and functions of this embodiment will be described in detail below. During the curing process of the plastic packaging film, after the curing process is completed, the connecting frame 42 can move linearly along a predetermined trajectory via the driving action of the cylinder 41. During the movement of the connecting frame 42, the first curing frame 43 fixed on it will move synchronously, thereby realizing the operation of the first curing frame 43 gradually moving outward from the inside of the curing box 1. Simultaneously, the support plate 49 connected to the first curing frame 43 will also slide along with the overall structure. During the sliding process, the support plate 49 will simultaneously drive the first movable rod 46 and the second movable rod 48 to move synchronously.

[0025] Because the second movable rod 48 and the second curing rack 44 are connected by a transmission mechanism, the second curing rack 44 will also move outward under the push of the support plate 49. In this process, not only can the second curing rack 44 be gradually pushed out of the inner cavity of the curing box 1, but the first curing rack 43 can also be released simultaneously under the structural linkage, so that the operator can easily take out the plastic packaging film that has been cured on its surface, improving the convenience of subsequent transfer or material replacement.

[0026] Furthermore, as the second curing rack 44 continues to move outward, the movable block 47 connected to its bottom will slide along the guide groove 451 provided on the side plate 45. As the movable block 47 gradually moves forward along the guide groove 451, due to the inclined guide rail structure of the guide groove 451, it will also generate an upward guiding force on the second curing rack 44, causing it to gradually rise. This rising action allows the second curing rack 44 to be in a state slightly higher than the initial horizontal position after it has completely moved out of the curing chamber cavity.

[0027] The raised structure design has two significant advantages: First, it provides ample vertical space for the operator to easily remove the plastic packaging film from the surface of the first curing rack 43, avoiding operational inconvenience caused by space constraints; second, by appropriately raising the second curing rack 44, it can effectively prevent accidental contact or interference during film removal, improving operational safety and efficiency.

[0028] Example 2: Figure 1 and Figure 2 As shown, the side plate 45 is fixedly connected to the inner wall of the cylinder 41. Both the second curing rack 44 and the first curing rack 43 have openings on their surfaces, with the second curing rack 44 located above the first curing rack 43. A cylinder 41 is installed on one side of the curing box 1, and the output end of the cylinder 41 is fixedly connected to the connecting frame 42. Air outlets 21 are provided on both sides of the filter box 2, and a filter element 22 is fixedly installed at the bottom of the inner cavity of the filter box 2. Two doors 3 are hinged to the side wall of the curing box 1.

[0029] The overall effect of this embodiment is that, during the curing process, the filter box 2 plays a crucial role in exhaust and purification. Through the filter box 2, the exhaust gas generated inside the curing box 1 can be effectively discharged, ensuring stable internal pressure and preventing the accumulation of harmful gases that could affect the curing effect. The air outlet 21 on the filter box 2 is reasonably designed to ensure normal airflow inside the packaging, allowing gas to flow out smoothly without blockage and effectively maintaining the airflow balance of the system.

[0030] More importantly, the filter element 22 installed inside the filter box 2 performs multi-level filtration of the exhaust gas, effectively trapping harmful substances and fine particles, preventing these pollutants from being directly discharged into the environment without treatment, thereby effectively reducing the risk of pollution to the surrounding environment. The filter element 22 is made of high-efficiency and environmentally friendly materials, possessing good filtration accuracy and a long service life, and can meet the continuous operation requirements of the curing process.

[0031] Furthermore, the filter box 2 is cleverly installed inside the mounting port 11, facilitating regular disassembly and replacement of the filter element 22 by maintenance personnel, ensuring that the filtration device is always in optimal working condition. This convenient replacement method not only reduces maintenance time but also minimizes the impact of equipment downtime on production efficiency.

[0032] The device's operation and working principle are as follows: During the curing process of the plastic packaging film, after curing is complete, the cylinder 41 pushes the connecting frame 42 to move. During the movement of the connecting frame 42, the first curing frame 43 moves along with it. At this time, the support plate 49 moves accordingly, causing the first movable rod 46 and the second movable rod 48 to move together, thereby causing the second curing frame 44 to move synchronously. This process not only pushes out the second curing frame 44 but also facilitates the removal of the cured plastic packaging film from the first curing frame 43.

[0033] As the second curing rack 44 moves, the moving block 47 slides along the slide 451. As the slide 451 continues to move, the second curing rack 44 will rise. After the second curing rack 44 is removed from the inner cavity of the curing box 1, it will slide upward to provide sufficient space for removing the plastic packaging film from the surface of the first curing rack 43, while avoiding contact with the second curing rack 44.

[0034] During the curing process, exhaust is achieved using the filter box 2, with the exhaust port 21 ensuring normal air circulation within the packaging. Some harmful gases are filtered through the filter element 22, preventing indiscriminate emissions that could pollute the environment. The filter box 2 is installed inside the mounting port 11, and the filter element 22 can be replaced periodically, thus ensuring the stability and effectiveness of the overall air filtration.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
