Detailed Implementation
[0030] 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.
[0031] This utility model provides, for example Figures 1-4The illustrated film feeding and conveying mechanism includes a frame, comprising a vertically arranged frame vertical plate 100 and a frame horizontal plate 101 perpendicular to the top of the frame vertical plate 100. The conveying assembly includes a film feeding assembly installed at the middle of the frame vertical plate 100 and a film conveying assembly installed inside the frame horizontal plate 101. The tension adjustment mechanism includes an adjusting roller 108 movably disposed inside the frame horizontal plate 101 and a horizontal displacement mechanism disposed between the frame horizontal plate 101 and the adjusting roller 108. The horizontal displacement mechanism is used to adjust the horizontal position of the adjusting roller 108 within the frame horizontal plate 101. The tension adjustment mechanism is located on the side of the film conveying assembly away from the film feeding assembly. An auxiliary tensioning mechanism is provided at the end of the frame horizontal plate 101 away from the film conveying assembly. The auxiliary tensioning mechanism is used to adjust the horizontal position of the adjusting roller 108 within the frame horizontal plate 101. The packaging film undergoes secondary tensioning. The film is released by the film-releasing assembly and then directionally transported by the film-carrying assembly, achieving stable delivery. Since the film needs to pass through the outer wall of the adjusting roller 108 in the tensioning mechanism, the horizontal displacement mechanism adjusts the horizontal position of the adjusting roller 108, dynamically adjusting the horizontal distance between the adjusting roller 108 and the film-carrying assembly. This adjusts the tension of the packaging film, ensuring it maintains appropriate tension during transport and preventing loosening that could affect normal delivery. Furthermore, the auxiliary tensioning mechanism supports and guides the film, ensuring it maintains tension and winds around the outer wall of the adjusting roller 108 when positioned between the film-carrying assembly and the auxiliary tensioning mechanism.
[0032] The film-laying assembly includes a mounting base 103. A support shaft is rotatably connected to the end of the mounting base 103 near the vertical plate 100 of the frame. The support shaft is fixedly connected to the inner wall of the vertical plate 100. A film-laying motor 105 is fixedly mounted on the end side wall of the mounting base 103 away from the vertical plate 100. The output end of the film-laying motor 105 passes through the side wall of the mounting base 103 and is connected to a film-laying pressure roller 104. The two ends of a lifting cylinder 106 are hinged to the mounting base 103 and the inner side of the vertical plate 100, respectively. In this embodiment, through… The film unwinding motor 105 drives the film unwinding pressure roller 104 to rotate, which in turn unwinds the packaging film wrapped around its outer wall. The packaging film is then transported along the film feeding assembly. The height of the film unwinding motor 105 and the film unwinding pressure roller 104 can be adjusted through the rotational connection of the mounting base 103 and the lifting action of the lifting cylinder 106. This gives the film unwinding assembly an adjustment function, allowing the tension of the packaging film at the unwinding position to be adjusted by the lifting and lowering drive of the lifting cylinder 106 during the unwinding process.
[0033] The film feeding assembly includes multiple transmission rollers 107, which are arranged in an array and rotate at intervals on the inner side of the frame horizontal plate 101 near the end of the frame vertical plate 100. The packaging film passes around the outer wall of the multiple transmission rollers 107 in sequence along the direction away from the film feeding assembly. The multiple transmission rollers 107 are arranged alternately in a horizontal straight line, so that the packaging film can be transported in a preset direction after passing around the outer wall of the transmission rollers 107 in sequence, while ensuring that the packaging film on the film feeding pressure roller 104 can be stably transported after being unwound.
[0034] The horizontal displacement mechanism includes a bearing slider 109, which is rotatably connected to the end of the adjusting roller 108. A threaded rod 110 is rotatably disposed on the inner wall of the frame cross plate 101, and its outer wall is threaded into the middle of the bearing slider 109. An adjusting rod 111 is disposed parallel to one side below the adjusting roller 108 and rotatably connected to the frame cross plate 101. Reversing bevel gears 112 are fixedly connected to both ends of the adjusting rod 111 and the end of the threaded rod 110 near the adjusting rod 111. Adjacent reversing bevel gears 112 mesh with each other, and one end of the adjusting rod 111 passes through the outer wall of the frame cross plate 101 and is fixedly connected to a handle. In this embodiment, a locking element can be installed between the adjusting rod 111 and the outer wall of the frame cross plate 101 to lock and limit the radial rotation of the adjusting rod 111. After adjustment, the position of the adjusting rod 111 should be kept stable to avoid misoperation. In specific operation, the user only needs to hold the handle to drive the adjusting rod 111 to rotate clockwise or counterclockwise. The adjusting rod 111 is driven by the reversing bevel gear 112 on it to mesh with the reversing bevel gear 112 at the end of the threaded rod 110, thereby driving the two threaded rods 110 to rotate synchronously. This drives the bearing slider 109 to move along the axial direction of the threaded rod 110. By adjusting the position of the bearing slider 109 on the threaded rod 110, the distance between the adjusting roller 108 and the nearest transmission roller 107 can be adjusted. In this way, by adjusting the distance between the adjusting roller 108 and the transmission roller 107, and with the packaging film wrapped from the outer wall of the transmission roller 107 to the outer wall of the adjusting roller 108, the tension of the packaging film during the transmission process can be achieved.
[0035] The auxiliary tensioning mechanism includes two swing plates 113, which are symmetrically arranged on the inner walls of both sides of the end of the frame horizontal plate 101. A rotating shaft 114 is rotatably connected between the end of the swing plates 113 and the inner wall of the frame horizontal plate 101. Two rollers 102 are rotatably connected to the two ends of the two swing plates 113, and retaining rings are fixedly connected to both ends of the outer wall of each roller 102. A pressing handle 115 is threaded to one end of the swing plate 113 near the frame horizontal plate 101, and one end of the pressing handle 115 extends into the swing plate 113 and contacts the outer wall of the corresponding rotating shaft 114. The packaging film passes alternately around the outer walls of the two rollers 102, which not only satisfies the need for tensioning the packaging film, but also... The conveying mechanism also provides auxiliary support for the packaging film, ensuring that the film remains taut between the conveying roller 107 and the roller 102. This facilitates the film passing through the outer wall of the adjusting roller 108 and adjusting its horizontal position to adjust the film tension. Furthermore, since the swing plate 113 is rotatably connected to the frame cross plate 101 via the rotating shaft 114, the two rollers 102 can be tilted by rotating the swing plate 113, thereby adjusting the film tension. This expands the adjustable range of film tension. By rotating the pressing handle 115, the end of the pressing handle 115 presses against the outer wall of the rotating shaft 114 at the corresponding position.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
