Description
Technical Field
[0001] This utility model relates to the field of packaging machinery, and in particular to a fully automatic pillow packaging machine. Background Technology
[0002] Currently, when packaging wide items, extra-wide film (over 1.6 meters wide) is used. However, existing packaging films are stored in rolls, and each roll is typically very long, resulting in a very heavy roll when made into extra-wide film. Furthermore, most existing packaging machines can only accommodate narrow film rolls, and these machines are equipped with unwinding reels for mounting the rolls. Therefore, most machines cannot accommodate extra-wide film, and even those that can often make mounting them difficult due to their weight and width. Consequently, packaging with extra-wide film is mostly done manually, which is prone to low efficiency, high costs, errors, and inconsistent quality. Therefore, it is essential to provide a fully automatic pillow-type packaging machine based on extra-wide film to solve these technical problems. Utility Model Content

[0020] like Figure 1 As shown, the fully automatic pillow packaging machine based on ultra-wide film of this utility model includes a material conveying device 1, a film folding and bag making device 2, a center sealing device 3, and an end sealing and film cutting device 4. The film folding and bag making device 2, the center sealing device 3, and the end sealing and film cutting device 4 are arranged sequentially on the material conveying device 1 along the conveying direction of the material conveying device 1. In order to achieve the purpose of this utility model, a rolling film supporting device 5 is also included, which is arranged on the input end of the material conveying device 1.
[0021] This fully automatic pillow packaging machine employs a rolling film support device 5 to support and unwind ultra-wide film rolls, eliminating the need for an unwinding shaft. This not only facilitates stable and accurate support of heavy and wide ultra-wide film rolls but also significantly improves the ease of loading and unloading. Furthermore, the machine includes a material conveying device 1, a film folding and bag-making device 2, a center-sealing device 3, and an end-sealing and film-cutting device 4, achieving fully automated packaging with a high degree of automation. This improves packaging efficiency, reduces costs, minimizes errors, and ultimately ensures more consistent packaging quality.
[0022] like Figure 1 and Figure 2 As shown, the rolling film support device 5 includes a frame 51, a rotary drive mechanism 52, and two rollers 53. The frame 51 is mounted on the material conveying device 1, and the rotary drive mechanism 52 is mounted on the frame 51 and / or the material conveying device 1. The two rollers 53 are horizontally arranged side by side on the frame 51, and are parallel to each other. At least one of the two rollers 53 is driven and connected to the rotary drive mechanism 52. This rolling film support device 5 is very simple and reliable. It is not only easy to manufacture, but also provides a stable and reliable support effect for ultra-wide film rolls. Its film feeding is smoother, making it convenient and quick to load and unload ultra-heavy and ultra-wide packaging films, and easy to adjust. This helps to further improve the reliability and applicability of the fully automatic pillow packaging machine.
[0023] The rotary drive mechanism 52 consists of a drive motor and a gearbox, which helps to output a stable rotary force, thereby improving the accuracy of film placement.
[0024] like Figure 2 As shown, the roller body 53 includes a rotating shaft 531 and at least one rubber roller 532. The rotating shaft 531 is rotatably mounted on the frame 51 and is driven by a rotary drive mechanism 52. The rubber roller 532 is fixedly mounted on the rotating shaft 531. This roller body 53 not only has a very simple structure but also provides good driving and support for ultra-wide film rolls, preventing scratches on the ultra-wide film during driving, thereby helping to further improve the reliability and applicability of the fully automatic pillow packaging machine.
[0025] like Figure 2As shown, a swing frame 54 is provided on the frame 51, and a roller 55 parallel to the roller body 53 is provided on the swing frame 54. The roller 55 can move in and out above the roller body 53 as the swing frame 54 swings. This allows the roller 55 to restrict the ultra-wide film roll, which helps to further improve the stability and reliability of the ultra-wide film roll placement. The swing frame 54 not only allows the roller body 53 to play a limiting role in the ultra-wide film roll, but also swings open to provide more open space above the roller body 53, thus making the installation and removal of the ultra-wide film roll very convenient.
[0026] like Figure 2 As shown, two rollers 53 jointly support the ultra-wide film roll 10; the frame 51 is equipped with a tension roller 56, a transition roller 57, a color mark photoelectric sensor 58, and a control photoelectric sensor 59; the tension roller 56 and the transition roller 57 can be used to tension and guide the ultra-wide film, thereby facilitating stable output of the ultra-wide film, preventing wrinkles during bagging, and making it smoother; the installation of the color mark photoelectric sensor 58 allows for two solutions: fixed-length packaging and tracking color mark packaging; the installation of the control photoelectric sensor 59 serves the purpose of monitoring and positioning; the swing frame 54 is hinged to the frame 51, and after the swing frame 54 swings into position, it is locked to the frame 51 by screws; this ensures that the unwinding of the rolling film support device 5 is very accurate and stable, which can well meet the needs of actual use.
[0027] like Figure 1 and Figure 3 As shown, the folding and bag-making device 2 includes two lower folding cardboard bodies 21 and two upper folding cardboard bodies 22. The two lower folding cardboard bodies 21 are arranged on both sides of the material conveying device 1 in the conveying direction, with a material passage gap 23 reserved between them. The two upper folding cardboard bodies 22 are arranged on both sides of the material conveying device 1 in the conveying direction, with each upper folding cardboard body 22 positioned above and behind the two lower folding cardboard bodies 21. A funnel-shaped closing gap 24 is reserved between the two upper folding cardboard bodies 22. This folding and bag-making device 2 not only has a simple structure but also facilitates the accurate and stable guidance of the ultra-wide film onto the center sealing device 3, making the packaging film less prone to deviation. The packaging film wraps the material more tightly, thereby improving the accuracy of the center sealing and, consequently, the quality of the center sealing.
[0028] like Figure 3 As shown, two lower folding cardboard bodies 21 are mounted on the screw adjusting assembly 25. The screws at both ends of the screw adjusting assembly 25 have opposite threads. The two lower folding cardboard bodies 21 are respectively screwed to the two ends of the screw of the screw adjusting assembly 25. In this way, the width of the material passage gap 23 can be adjusted by the screw adjusting assembly 25, thereby meeting the needs of packaging films of different widths and packaging materials of different widths. It has a wide range of applications and can adapt to extra-large materials, thus meeting different usage needs.
[0029] like Figure 3 As shown, the upper folding cardboard body 22 includes a positioning plate 221, a bag-forming adjusting plate 222, and a guide plate 223. The positioning plate 221 is disposed on the side of the material conveying position on the material conveying device 1. The bag-forming adjusting plate 222 is horizontally rotatable and lockably disposed on the outer upper side of the positioning plate 221 facing the input end of the material conveying device 1. The guide plate 223 is disposed on the inner upper side of the positioning plate 221, and its width gradually increases along the conveying direction of the material conveying device 1. This upper folding cardboard body 22 can reduce the impact of overweight or oversized materials on the packaging film when entering the folding and bag-making device 2, preventing the packaging film from wrinkling or deviating, and ensuring smooth bag formation. This upper folding cardboard body 22 not only has a simple structure but also facilitates accurate and stable guidance and allows for different guiding effects, thereby helping to further improve the reliability and applicability of the fully automatic pillow packaging machine.
[0030] The bag-forming adjustment plate 222 can be locked onto the positioning plate 221 by bolts (not shown in the figure). Several locking holes are provided on the positioning plate 221 or other auxiliary connecting plates to provide different locking positions for the bolts. This satisfies the dual requirements of locking and adjustment, and thus can well meet the needs of actual use.
[0031] like Figure 1 As shown, a middle sealing brush assembly 6 is provided between the middle sealing device 3 and the end sealing and film cutting device 4. The middle sealing brush assembly 6 includes a drive chain and several brush bodies. The drive chain is driven in the same direction as the material conveying device 1, and each brush body is disposed on the outer wall of the drive chain. The brush bodies can be used to comb the ultra-wide film to make it smooth, thereby improving the quality of end sealing and film cutting.
[0032] The material conveying device 1 uses a belt conveyor, and the input end of the material conveying device 1 is placed under the folding and bag making device 2. This ensures that overweight and oversized materials run smoothly in the packaging machine and that the packaging process proceeds in an orderly manner.
[0033] like Figure 1 and Figure 5 As shown, the end-sealing and film-cutting device 4 includes an opening and closing film clamping mechanism 41 and a cutting mechanism 42. The cutting mechanism 42 is mounted on the opening and closing film clamping mechanism 41, and after the opening and closing film clamping mechanism 41 is closed, the cutting end of the cutting mechanism 42 can enter and exit the closed opening of the opening and closing film clamping mechanism 41. Such an end-sealing and film-cutting device 4 not only facilitates effective heat sealing but also facilitates accurate cutting, thereby ensuring that the fully automatic pillow packaging machine has very high reliability and applicability.
[0034] like Figure 5As shown, the opening and closing film clamping mechanism 41 includes a positioning frame 411 and two lifting film clamping mechanisms 412. The lifting film clamping mechanism 412 includes a lifting frame 4121, a film clamping strip 4122, and at least one driving cylinder 4123. The driving cylinder 4123 is vertically mounted on the positioning frame 411, and the lifting frame 4121 is vertically slidably mounted on the positioning frame 411, driving the lifting frame 4121 and the driving cylinder 4123. The film clamping strip 4122 is horizontally mounted on the lifting frame 4121. The film clamping strips 4122 on the two lifting film clamping mechanisms 412 are arranged vertically opposite each other, and cutting grooves 4124 are respectively opened on the opposite surfaces of the two film clamping strips 4122. The cutting mechanism 42 is mounted on the lifting frame 4121 of one of the lifting film clamping mechanisms 412, and the cutting end of the cutting mechanism 42 can move up and down in the two cutting grooves 4124 to perform the cutting action. Such an opening and closing film clamping mechanism 41 is very simple and reliable. It is not only easy to manufacture, but also conducive to a very stable heat sealing effect and accurate and stable cutting, thereby helping to further improve reliability and applicability.
[0035] like Figure 5 As shown, the cutting mechanism 42 includes a cutting cylinder 421, a lifting rod 422, and a serrated bar 423. The cutting cylinder 421 is vertically mounted on the lifting frame 4121. The lifting rod 422 is vertically slidably mounted on the lifting frame 4121 and is driven by the cutting cylinder 421. The serrated bar 423 is horizontally arranged in the cutting groove 4124, with the serrated portion of the serrated bar 423 facing outwards from the opening of the cutting groove 4124, and is connected to the lifting rod 422. This cutting mechanism 42 has a very simple and reliable structure, which not only facilitates manufacturing but also improves the smoothness and quality of cutting, thereby contributing to further improving the reliability and applicability of the fully automatic pillow packaging machine.
[0036] The lifting frame 4121 and the piston rod of the drive cylinder 4123 are connected by a threaded fitting. This not only facilitates a reliable connection but also allows for adjustment of the height of the clamping strip 4122. Furthermore, the drive cylinder 4123 itself is also height-adjustable, thus meeting the requirements for the sealing center position of materials with varying heights. The clamping strip 4122 uses a combination of cross-ribbed rubber to adapt to the requirements of various packaging films, including composite films, demonstrating strong adaptability. The serrated strip 423 is a metal strip that can generate its own heat and also achieve heat-cutting and sealing via an electric heating strip mounted on the clamping strip 4122, ensuring excellent end-sealing quality.
[0037] like Figure 5As shown, the positioning frame 411 is provided with two opposing corner insert assemblies 43. Each corner insert assembly 43 includes a corner insert cylinder 431, a horizontal slide 432, and two triangular corner insert plates 433. The corner insert cylinder 431 is mounted on the positioning frame 411. The horizontal slide 432 is horizontally slidable on the positioning frame 411, with its horizontal sliding direction perpendicular to the conveying direction of the material conveying device 1. The two triangular corner insert plates 433 are arranged side-by-side along the conveying direction of the material conveying device 1, and are parallel to each other. A clearance 434 is reserved between the two triangular corner insert plates 433 for the lifting and lowering of the film clamping strip 4122, and the corners of the triangular corner insert plates 433 on the two corner insert assemblies 43 are arranged opposite each other. The corner insert assembly 43 further improves the quality of heat sealing and cutting, thereby contributing to further improvement in packaging quality.
[0038] This fully automatic pillow-type packaging machine is suitable for packaging oversized and heavy materials (such as secondary packaging of large boxes, door panels, glass platforms, and 300×300×3000 steel pipes); it is also suitable for the combination packaging of bulk materials (such as 40 rolls of paper); and for other packaging requiring back-side sealing for automated feeding. It has a wide range of applications, reducing labor intensity while improving packaging yield and efficiency.
[0039] In actual use, an extra-wide film roll 10 is placed on the rolling film support device 5, and the extra-wide film roll 10 passes sequentially around the folding and bag-making device 2, the center sealing device 3, and the end sealing and cutting device 4; the material to be packaged enters the extra-wide film on the folding and bag-making device 2 through the material conveying device 1 and is wrapped by the extra-wide film, and then is sealed sequentially (the extra-wide film is folded in half along the width direction on the folding and bag-making device 2 and then pressed together, and the sides of the extra-wide film are sealed and connected together by the center sealing device 3), and finally the end sealing and cutting device 4 is used to seal and cut the film, thus achieving normal packaging requirements.
