Description

Technical Field

[0001] This utility model relates to the technical field of paper-plastic composite bag production equipment, and in particular to a renewable and environmentally friendly paper-plastic composite bag production device. Background Technology

[0002] The renewable and environmentally friendly paper-plastic composite bag production equipment is an intelligent production line that integrates papermaking, lamination, and molding. It uses recycled pulp and bio-based plastics (such as PLA / PHA) as raw materials to produce fully biodegradable paper-plastic composite packaging bags. Its core breakthrough lies in achieving the environmental goal of "zero chemical pollution + 100% compostability" while maintaining the mechanical strength of traditional plastic packaging.

[0003] Chinese Patent CN218197271U discloses a production apparatus for renewable and environmentally friendly paper-plastic composite bags, including a machine base. One end of the machine base has upper and lower feeding shafts arranged vertically, and the other end has a feeding shaft. The feeding shaft is connected to a motor via a transmission mechanism. A glue-applying device is located above the machine base. One end of the glue-applying device is slidably connected to a transverse electric slide rail via a slider. One end of the transverse electric slide rail is movably connected to a bracket connected to the machine base. A glue-spreading plate is located on one side of the glue-spreading device. The top of the glue-spreading plate is connected to an L-shaped bracket. A pressing and laminating mechanism is located on one side of the glue-spreading plate, which can horizontally press and laminate the composite paper strip and film strip. A glue-fixing device is located on one side of the pressing and laminating mechanism, which can spread the glue evenly after the paper strip is coated, facilitating the pressing and laminating with the film strip. The pressing conveyor belt maintains a horizontal state to press and laminate the composite paper strip and film strip, resulting in thorough lamination and higher quality.

[0004] Although the above-mentioned device can facilitate the pressing and lamination of film tape, the inventors found in practical applications that the paper-plastic composite tape cannot be smoothed before applying glue, resulting in wrinkles and uneven glue application. Therefore, we propose a renewable and environmentally friendly paper-plastic composite bag production device. Utility Model Content

[0005] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0006] Specifically, the technical problem to be solved by this utility model is to provide a renewable and environmentally friendly paper-plastic composite bag production device to solve the current technical problem that the paper-plastic composite tape cannot be smoothed before applying glue, resulting in wrinkles and uneven glue application.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A renewable and environmentally friendly paper-plastic composite bag production device includes a frame, a feeding rack fixedly installed on the top of the frame, a first fixing plate fixedly installed on the top of the frame, and a second fixing plate fixedly installed on the top of the frame, with the first fixing plate located between the feeding rack and the second fixing plate.

[0009] A smoothing device includes a first smoothing roller rotatably mounted on the inner side of the first fixed plate, a second smoothing roller rotatably mounted on the inner side of the first fixed plate, and a third smoothing roller rotatably mounted on the inner side of the second fixed plate. The first smoothing roller and the second smoothing roller are arranged parallel to each other, and the first smoothing roller is located above the second smoothing roller. When in operation, the paper-plastic composite tape on the feeding rack passes above the first smoothing roller, below the second smoothing roller, and then above the third smoothing roller. The paper-plastic composite tape is driven by an external winding mechanism.

[0010] As an improved technical solution, a fixed frame is fixedly installed on the frame, and the fixed frame is located between the first fixed plate and the second fixed plate. A glue storage box is installed on the fixed frame. A plurality of glue hoppers are installed on the bottom wall of the inner cavity of the glue storage box, and the glue hoppers are connected to the glue storage box. A glue scraper is fixedly installed on the glue storage box, and the plurality of glue hoppers are located above the paper-plastic composite belt.

[0011] As an improved technical solution, the fixing frame consists of a vertical fixing part and a horizontal connecting part. The vertical fixing part is installed on the top of the frame, and the glue storage box is installed through the interior of the horizontal connecting part.

[0012] As an improved technical solution, several of the glue hoppers are equidistantly arranged along the length of the glue storage box.

[0013] As an improved technical solution, the lower glue hopper is a hollow cone shape, and the upper diameter of the lower glue hopper is larger than the lower diameter of the lower glue hopper.

[0014] As an improved technical solution, the glue scraper includes a connecting plate, one end of which is fixedly installed on the vertical fixing part of the fixing frame, and the other end of which is rotatably installed with a scraper. The bottom of the scraper has an integrally formed scraper head, and a glue application gap is reserved between the scraper head and the paper-plastic composite tape.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. This utility model involves smoothing one end of a paper-plastic composite belt on a feeding rack and fixing the other end of the paper-plastic composite belt to an external winding mechanism. At this time, the paper-plastic composite belt passes over the first smoothing roller, below the second smoothing roller, and over the third smoothing roller. Then, the external winding mechanism is activated. The first and second smoothing rollers smooth the paper-plastic composite belt, while the third smoothing roller plays an auxiliary conveying role. The paper-plastic composite belt is then conveyed to the next process by the external winding mechanism, which facilitates the smoothing treatment of the paper-plastic composite belt and avoids uneven glue application caused by wrinkles in the paper-plastic composite belt.

[0017] 2. In this utility model, during the conveying of the paper-plastic composite belt, the glue in the glue storage box falls onto the paper-plastic composite belt through the inner cavity of the glue hopper, and is smoothed by the scraper head on the glue scraper to achieve a uniform glue coating effect, thereby facilitating the glue coating of the paper-plastic composite belt and ensuring uniform glue coating.

This renewable and environmentally friendly paper-plastic composite bag production device includes a frame 1, a feeding rack 101 fixedly installed on the top of the frame 1, a first fixing plate 102 fixedly installed on the top of the frame 1, and a second fixing plate 103 fixedly installed on the top of the frame 1, with the first fixing plate 102 located between the feeding rack 101 and the second fixing plate 103.

[0029] The smoothing device includes a first smoothing roller 2 rotatably mounted on the inner side of the first fixed plate 102, a second smoothing roller 3 rotatably mounted on the inner side of the first fixed plate 102, and a third smoothing roller 4 rotatably mounted on the inner side of the second fixed plate 103. The first smoothing roller 2 and the second smoothing roller 3 are arranged parallel to each other, with the first smoothing roller 2 located above the second smoothing roller 3. When in operation, the paper-plastic composite tape (made of renewable and environmentally friendly materials) on the feeding rack 101 passes above the first smoothing roller 2, below the second smoothing roller 3, and then above the third smoothing roller 4. The paper-plastic composite tape is driven by an external winding mechanism. In use, one end of the paper-plastic composite belt on the feeding rack 101 is passed through a smoothing device and fixed to an external winding mechanism. At this time, the paper-plastic composite belt passes over the first smoothing roller 2, below the second smoothing roller 3, and above the third smoothing roller 4. Then the external winding mechanism is started. At this time, the first smoothing roller 2 and the second smoothing roller 3 smooth the paper-plastic composite belt, while the third smoothing roller 4 plays an auxiliary conveying role. The paper-plastic composite belt is then conveyed to the next process by the external winding mechanism, which facilitates the smoothing treatment of the paper-plastic composite belt and avoids uneven glue coating caused by wrinkles in the paper-plastic composite belt.

[0030] Reference Figures 1-3 A fixed frame 5 is fixedly installed on the frame 1, and the fixed frame 5 is located between the first fixed plate 102 and the second fixed plate 103. A glue storage box 6 is installed on the fixed frame 5. Several glue hoppers 7 are installed on the bottom wall of the inner cavity of the glue storage box 6, and the glue hoppers 7 are connected to the glue storage box 6. A glue scraper is fixedly installed on the glue storage box 6. The several glue hoppers 7 are located above the paper-plastic composite belt. In application, when the paper-plastic composite belt is being conveyed, the glue in the glue storage box 6 falls onto the paper-plastic composite belt through the inner cavity of the glue hoppers 7, and is scraped flat by the glue scraper to achieve a uniform glue coating effect.

[0031] Reference Figure 2 and Figure 3 The fixing frame 5 consists of a vertical fixing part and a horizontal connecting part. The vertical fixing part is installed on the top of the frame 1, and the glue storage box 6 is installed through the interior of the horizontal connecting part to facilitate the installation and fixing of the fixing frame 5.

[0032] Reference Figure 2 and Figure 3 Several glue hoppers 7 are equidistantly arranged along the length of the glue storage box 6 to facilitate the installation of the glue hoppers 7 and thus facilitate uniform glue application.

[0033] Reference Figure 2 and Figure 3 The glue hopper 7 is a hollow cone shape, and the upper diameter of the glue hopper 7 is larger than the lower diameter of the glue hopper 7, so as to facilitate glue dispensing.

[0034] Reference Figure 2 and Figure 3 The glue scraper includes a connecting plate 801. One end of the connecting plate 801 is fixedly installed on the vertical fixing part of the fixing frame 5. The other end of the connecting plate 801 is rotatably installed with a scraper 802. The bottom of the scraper 802 has an integrally formed scraper head 803, and a glue application gap is reserved between the scraper head 803 and the paper-plastic composite tape to facilitate scraping the glue on the paper-plastic composite tape.

[0035] During use, one end of the paper-plastic composite belt on the feeding rack 101 is passed through the smoothing device, and the other end of the paper-plastic composite belt is fixed to the external winding mechanism. At this time, the paper-plastic composite belt passes above the first smoothing roller 2, below the second smoothing roller 3, and above the third smoothing roller 4 (e.g., Figure 1 As shown in the diagram, the external winding mechanism is then activated. At this time, the first smoothing roller 2 and the second smoothing roller 3 smooth the paper-plastic composite belt, while the third smoothing roller 4 plays an auxiliary role in conveying the paper-plastic composite belt. Meanwhile, the glue in the glue storage box 6 falls onto the paper-plastic composite belt through the inner cavity of the glue hopper 7, and is smoothed by the scraper head 803 on the glue scraper to achieve a uniform glue coating effect. Then, the external winding mechanism conveys it to the next process, which facilitates the smoothing treatment of the paper-plastic composite belt and avoids the phenomenon of uneven glue coating caused by wrinkles in the paper-plastic composite belt.

This device not only facilitates the smoothing of the paper-plastic composite strip, but also avoids uneven glue application caused by wrinkles in the paper-plastic composite strip.
