[0002] With the continuous improvement of people's living standards, packaging bags have become an indispensable packaging product in people's lives. Packaging bags refer to bags used to package various items, making it convenient for goods to be transported during production and distribution. Packaging bags are manufactured through bag-making machines. In the production process, the film needs to be conveyed, and then the bag-making machine and other equipment are used to complete the bag-making process.

[0003] However, there are certain defects in actual production and use. When the film roll is about to run out, the machine needs to be stopped to replace it with a new roll, which affects the continuity of processing. Although some rolls can be automatically changed and spliced, they cannot be positioned and fixed well, which may cause deviations and affect the quality and effect of splicing. Utility Model Content

[0004] The purpose of this utility model is to provide a fully automatic film splicing device for a packaging bag making machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic film splicing device for a packaging bag making machine, comprising a processing table, a bag making machine body on the processing table, a first film roll and a second film roll sequentially mounted on one end of the processing table via an installation component, a suction component on the processing table via an adjustment mechanism, a guide component on the processing table, the guide component being located between the installation component and the bag making machine body, and a film splicing component also being mounted on the processing table above the guide component.

[0006] Preferably, in order to facilitate the installation of the first film roll and ensure stability and firmness, an extension plate is symmetrically provided at the end of the processing table away from the main body of the bag making machine, and the extension plate is fixedly connected to the side wall of the processing table by a support rod.

[0008] Preferably, in order to facilitate the reciprocating movement of the suction component, to facilitate the suction and movement of new film, and to facilitate subsequent film splicing operations, the adjustment mechanism includes a linear guide rail device symmetrically arranged on the processing table and the extension plate. The linear guide rail device is provided with a guide rail slider, and the guide rail slider is symmetrically provided with an electric push rod. An adjustment plate is fixedly provided at the output end of the electric push rod.

[0009] Preferably, in order to facilitate the suction of new membranes and the end contact and splicing of the previous membrane, and to facilitate membrane splicing, the suction assembly includes suction cups equidistantly arranged on the adjustment plate. The bottom of the suction cups is provided with a connecting tube, which passes through the adjustment plate and extends downward to connect with the output end of the vacuum generator. The vacuum generator is fixedly connected to the bottom of the adjustment plate.

[0010] Preferably, in order to facilitate guiding and limiting the film conveying process, and to facilitate placing the film on the top of the mounting frame for subsequent heat sealing, the guiding component includes a mounting frame fixedly mounted on the processing table, with a guide roller rotatably mounted at one end of the mounting frame near the main body of the bag making machine.

[0011] Preferably, in order to facilitate the fusion of the heat-sealing layer and form a continuous sealed joint to complete the film splicing operation, the film splicing assembly includes hydraulic telescopic rods symmetrically arranged on the processing table, a lifting plate fixedly provided at the output end of the hydraulic telescopic rod, and a heat-sealing knife body provided below the end of the lifting plate near the second film roll.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The adjustable mechanism, in conjunction with the suction component, allows for easy suction and movement of new rolls of film. The guide component facilitates the movement and positioning of the film, ensuring easy contact and positioning with the end of the previous film. This facilitates subsequent film splicing operations, making the process relatively simple, convenient, and suitable for continuous production while ensuring the effectiveness and quality of film splicing.

[0014] The guide assembly, in conjunction with the film splicing assembly, can conveniently guide and limit the film during processing and transportation, preventing deviation and ensuring that subsequent processing is not affected. The film splicing assembly can easily fuse the heat-sealing layers of two or more films by heating and pressurizing the used film end and the new film end to form a continuous sealed seam, thus completing the film splicing operation without affecting subsequent processing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This utility model provides an embodiment of a fully automatic film-sealing device for a packaging bag-making machine, including a processing table 1 for mounting and placing the main body 2 of the bag-making machine, ensuring the stability and firmness of the main body 2. The main body 2 of the bag-making machine mainly consists of components such as conveying, forming, heat sealing, cutting, and control systems, which are convenient to process and use and are relatively mature technologies, so they will not be described in detail here. An extension plate 7 is symmetrically welded to one end of the processing table 1. To ensure the stability and firmness of the extension plate 7, the bottom of the extension plate 7 is welded and fixed to the side wall of the processing table 1 by a support rod 12. Mounting plates 5 with mounting components are vertically welded on both plate 7 and processing table 1. Placement racks 6 are welded at equal intervals on the top of mounting plates 5 (preferably, there are two sets of placement racks 6 on one mounting plate 5). The first film roll 3 and the second film roll 4 are installed on the corresponding placement racks 6. The drive device (which may consist of a motor, a gearbox, etc., not shown in the figure) is installed on the corresponding placement rack 6. The conveying end of the drive device is connected to the first film roll 3 and the second film roll 4 respectively, which can conveniently rotate the first film roll 3 and the second film roll 4 respectively, which is convenient to cooperate with the bag making machine body 2 to convey and process the film.

[0023] Please see Figures 1-5To facilitate the suction and movement of the film, and to allow for the transfer of film from a spare roll after use during the bag-making process, ensuring seamless film splicing without affecting subsequent processing, a linear guide rail device 13 with an adjustment mechanism is installed on the processing table 1 and the extension plate 7. A guide rail slider 14 (which can be reciprocated by a linear motor or other mature technologies, will not be elaborated upon here) slides on the linear guide rail device 13. Electric push rods 15 are symmetrically mounted on the guide rail slider 14, and an adjustment plate 16 is fixedly mounted at the output end of the electric push rods 15. Suction cups 17 (preferably six sets, but other numbers such as four or eight sets) are equidistantly mounted on the adjustment plate 16 to facilitate film suction and subsequent movement. A connecting pipe 19 is provided at the bottom of the suction cups 17, passing through the adjustment plate 16 and extending downwards to connect with the output end of a vacuum generator 18. 18 (a relatively mature technology, not described in detail here) is fixedly connected to the bottom of the adjusting plate 16. In order to facilitate the guidance of the conveyed film and the bonding of the film, a guide component is provided between the mounting component and the main body 2 of the bag making machine. The guide component includes a mounting frame 11 fixed (by screws or welding) on ​​the processing table 1. A guide roller 20 is rotatably provided at one end of the mounting frame 11 near the main body 2 of the bag making machine to facilitate the guidance of the conveyed film. The processing table 1 is provided with a film bonding component above the guide component. The film bonding component includes hydraulic telescopic rods 10 symmetrically arranged on the processing table 1. A lifting plate 8 is fixedly provided at the output end of the hydraulic telescopic rod 10. A heat sealing knife body 9 is provided below one end of the lifting plate 8 near the second film roll 4. The heat sealing knife body 9 can be a Teflon-coated heat sealing knife to reduce the risk of mold sticking. It can also work with the hydraulic telescopic rod 10 to apply pressure to promote the full contact and bonding of the molten film layer. This is a relatively mature technology, not described in detail here.

[0024] Working Principle: In use, the first film roll 3 and the second film roll 4 are respectively installed on the placement frame 6. Initially, the film on the first film roll 3 is used in conjunction with the bag making machine body 2 for packaging. When the film on the first film roll 3 is about to run out, the linear guide rail device 13 moves the adjusting plate 16 on the guide rail slider 14, which moves the suction cup 17 below the second film roll 4. The drive device (not shown in the figure) rotates the second film roll 4, rotating the end of the film downwards. Then, the electric push rod 15 extends, moving the adjusting plate 16 upwards, and the suction cup 17 contacts the film. Through the vacuum generating device 18 and the connecting pipe 19, the film can be vacuumed through the suction cup 17. The film is absorbed and then moves towards the main body 2 of the bag making machine via the linear guide rail device 13, carrying the guide rail slider 14. The drive device and the second film roll 4 can transport the film. At this time, the end of the adjusting plate 16 contacts the end of the mounting frame 11, and the end of the film on the second film roll 4 moves to the mounting frame 11 and contacts the end of the exhausted film on the first film roll 3. The hydraulic telescopic rod 10 retracts, carrying the lifting plate 8 and the heat sealing knife body 9 down to complete the film splicing operation. Then the hydraulic telescopic rod 10 extends and the electric push rod 15 retracts and resets, without affecting subsequent processing. At this time, the first film roll 3 can be easily replaced. When the second film roll 4 is exhausted, the above operation can be repeated to splice the film on the first film roll 3.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
