Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to an adjustable pusher structure for a packaging machine. Background Technology

[0002] In the production and assembly of sanitary napkin packaging machines, the mold pusher mechanism is the core component for achieving precise product delivery and ensuring packaging accuracy. The connection accuracy between the mold pusher mechanism and the mold profile directly affects the packaging quality. In existing technology, the connection between the packaging machine's mold pusher mechanism and the mold profile uses a non-adjustable fixed structure. This structure has the following drawbacks: Part errors cannot be adapted: Due to the unavoidable dimensional errors of parts during processing and assembly, the non-adjustable structure cannot compensate for the errors through adjustment, resulting in the actual position of the pusher head deviating from the design reference.

[0003] The remedial methods are inefficient: when misalignment occurs, the height / horizontal distance needs to be adjusted by repairing parts or inserting shims, which not only increases the working time, but may also cause secondary misalignment due to loose shims, affecting the stability of the equipment.

[0004] To address the aforementioned issues, this invention presents a multi-directionally adjustable pusher structure for packaging machines. Through structural optimization, error adaptation is achieved, thereby improving assembly efficiency and equipment stability. Utility Model Content

[0012] Figure 2 for Figure 1 A partial decomposition diagram. Detailed Implementation

[0013] 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.

[0014] Reference Figures 1-2As shown, one embodiment of this utility model provides an adjustable pusher structure for a packaging machine, including a main fixed plate 1, a center distance adjusting plate 2, an angle adjusting plate 3, a movable plate 4, and a locking assembly; the movable plate 4 is fixedly connected to the synchronous belt 5 of the packaging machine, the center distance adjusting plate 2 is movably connected to both the movable plate 4 and the angle adjusting plate 3, and the other side of the angle adjusting plate 3 is movably connected to the main fixed plate 1; a pusher 6 is provided at one end of the main fixed plate 1; the locking assembly includes a horizontal slotted hole 7, a vertical slotted hole 8, and screws and threaded holes 9; the movable plate 4 and the center distance adjusting plate 2 are connected by... The horizontal waist hole 7 is connected to a screw, and its horizontal position is adjusted by connecting to a different threaded hole on the movable plate 4. The angle adjustment plate 3 is connected to the center distance adjustment plate 2 by a vertical waist hole 8 and a screw. Similarly, the vertical waist hole 8 is connected to the center distance adjustment plate 2 by a different threaded hole to adjust the vertical height. Furthermore, by slightly rotating the vertical waist hole 8, a certain tilt can be made between the vertical waist hole 8 and the center distance adjustment plate 2, thereby completing the angle adjustment. The angle adjustment plate 3 is connected to the main fixing plate 1 by screws, thus serving to fix the push head. In this utility model, there are at least two horizontal and two vertical waist holes.

[0015] In this utility model, the center distance adjusting plate 2 includes a first connecting plate 10 and a second connecting plate 11. A horizontal waist hole 7 is provided on the first connecting plate 10, and a threaded hole 9 is provided on the second connecting plate 11. The threaded hole on the second connecting plate 11 is fitted with a vertical waist hole 8. The diameter of the vertical waist hole 8 is larger than the diameter of the threaded hole. The moving plate 4 and the second connecting plate 11 are provided with several rows and several columns of threaded holes. (Refer to...) Figure 2 As shown, the first connecting plate 10, installed with different threaded holes on the movable plate 4, can be used for horizontal adjustment. Similarly, the vertical waist hole 8, installed with threaded holes at different positions on the second connecting plate 11, can be used to adjust the vertical height. Furthermore, since the diameter of the vertical waist hole 8 is larger than that of the threaded hole, it can be slightly rotated to adjust the angle. For example, the angle adjustment plate has four waist holes, each 9mm wide, while the outer diameter of an M8 hex socket screw is generally around 8mm, slightly smaller than 8mm. Therefore, there is a 1mm gap between the screw and the waist hole, or 0.5mm on each side. This gap allows the angle adjustment plate to slightly adjust its angle (e.g., less than 0.5mm on the left and greater than 0.5mm on the right), creating a very small angle. After the angle is amplified by the 600mm long profile, the overall adjustment range becomes significant.

[0016] In this invention, alignment can also be achieved through the same row of threaded holes.

[0017] In this utility model, the lower end of the angle adjustment plate 3 and the main fixing plate 1 are provided with threaded holes. The angle adjustment plate 3 and the main fixing plate 1 are connected and fixed by screws passing through the threaded holes at the lower end of the main fixing plate 1 and engaging with the threaded holes.

[0018] In this utility model, the movable plate 4 is provided with a groove 12 for placing the timing belt. The timing belt is pressed by the pressure plate 13 and locked to the threaded hole on the movable plate by a screw passing through the pressure plate.

[0019] Example 1: An adjustable pusher structure for a packaging machine includes a main fixed plate, a center distance adjustment plate, an angle adjustment plate, a movable plate, and a locking assembly. The movable plate is fixedly connected to the synchronous belt of the packaging machine. The center distance adjustment plate is movably connected to both the movable plate and the angle adjustment plate. The other side of the angle adjustment plate is movably connected to the main fixed plate. One end of the main fixed plate is provided with a pusher. The locking assembly includes a horizontal slotted hole, a vertical slotted hole, and an M8 hexagonal socket screw. The movable plate is connected to the center distance adjustment plate via the horizontal slotted hole and the M8 hexagonal socket screw. The angle adjustment plate is connected to the center distance adjustment plate via the vertical slotted hole and the M8 hexagonal socket screw. The angle adjustment plate is connected to the main fixed plate via the M8 hexagonal socket screw. The center distance adjustment plate includes an integrally formed first connecting plate and a second connecting plate; the horizontal waist holes are opened on the first connecting plate, numbering 2-4, and distributed parallel in the horizontal direction; the second connecting plate has 3-5 rows and 2-4 columns of threaded holes, and the vertical waist holes are opened on the angle adjustment plate and are installed in conjunction with the threaded holes of the second connecting plate. The diameter of the vertical waist holes (9mm) is larger than the diameter of the threaded holes (8mm); the movable plate also has 3-5 rows and 2-4 columns of threaded holes, which cooperate with the horizontal waist holes to achieve horizontal adjustment. The lower end of the angle adjustment plate and the corresponding position of the main fixing plate are provided with threaded holes. M8 hexagon socket screws are passed through the main fixing plate and fastened to the threaded holes at the lower end of the angle adjustment plate. The movable plate has a groove for placing the timing belt. A pressure plate is provided in the groove. The timing belt is locked by M8 hexagon socket screws passing through the pressure plate and the threaded holes on the movable plate.

[0020] Horizontal adjustment: The first connecting plate of the center distance adjustment plate is connected to the moving plate through a horizontal waist hole (50mm in length). After loosening the M8 hex socket screw, the center distance adjustment plate can be slid horizontally to achieve a horizontal distance adjustment of 0-50mm, which can accommodate the length error of the mold profile.

[0021] Vertical adjustment: The angle adjustment plate is connected to the second connecting plate of the center distance adjustment plate through the vertical waist hole (30mm in length). After loosening the screw, it can be moved in the vertical direction to achieve a vertical height adjustment of 0-30mm, which can accommodate the height deviation of the mounting hole.

[0022] Angle adjustment: Since the diameter of the vertical waist hole (9mm) is larger than the outer diameter of the screw (8mm), there is a 1mm gap. Slightly rotating the angle adjustment plate can make the vertical waist hole shift up and down (0-0.5mm adjustment on one side). Then, the vertical waist hole is pressed by the nut of the hexagonal screw. After being enlarged by the 600mm long mold profile, it can meet the angle adjustment requirement of ±0.5° and adapt to the assembly angle error.

[0023] 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.
