Description

Technical Field

[0001] This utility model relates to the field of aluminum packaging container processing equipment, specifically an aluminum flexible tube body closing and forming device. Background Technology

[0002] In the production and processing of aluminum flexible tubes, the end-folding machine is the core equipment for shaping the end of the tube. It folds and compacts the end of the filled aluminum tube to seal and preserve the contents. Currently, manual end-folding machines are still widely used in the market. These machines are particularly suitable for small to medium batch production due to their simple structure and low cost.

[0003] Existing manual tube bending machines typically lack a dedicated radial constraint structure for the aluminum tube. Before entering the bending processing station, the aluminum tube relies solely on manual support by the operator or simple lifting by the equipment for positioning. Due to the inherent length and weight of the aluminum tube, it is prone to sagging and shifting under its own weight, or tilting due to uneven force control during manual loading. This leads to misalignment between the tube's tail and the bending die, resulting in problems such as out-of-tolerance folding dimensions, tail wrinkles, and poor sealing, resulting in a high defect rate and poor product quality stability. Therefore, improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum flexible tube body closing and forming device to solve the problem of the lack of an effective radial constraint structure in conventional manual aluminum tube closing and folding machines mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum flexible tube body closing and forming device, including a tail-folding machine, wherein side plates are fixedly installed on the left and right sides of the tail-folding machine, and a pair of sliding rods are fixedly installed between the two side plates. The sliding rods are provided with a plurality of limiting components that can slide and adjust their positions along their length direction. The distance between the two limiting components can be adjusted to match the outer diameter of the aluminum flexible tube to be processed, so as to guide and limit the aluminum flexible tube.

[0006] Preferably, the side wall of the side plate is provided with a sliding hole for accommodating the slide rod, and the two ends of the slide rod are respectively locked between the side plates by nuts.

[0007] Preferably, the limiting component includes a sliding sleeve slidably mounted on the sliding rod. A plurality of L-shaped rods arranged in a circumferential pattern are slidably mounted on the inner sidewall of the sliding sleeve. One end of the plurality of L-shaped rods is fitted with a rubber ring. An adjusting sleeve is rotatably mounted on the inner wall of the sliding sleeve. The adjusting sleeve is provided with an arc-shaped hole for accommodating the L-shaped rod at a position corresponding to the L-shaped rod. The end of the L-shaped rod passes through the rubber ring and extends into the arc-shaped hole.

[0008] Preferably, the outer wall of the sliding sleeve is integrally formed with a hollow cylindrical structure, and a vertical rod is threadedly installed in the cylindrical structure.

[0009] Preferably, the outer side wall of the adjusting sleeve at the end away from the sliding sleeve is provided with an anti-slip ridge.

[0010] Preferably, the inner diameter of the rubber ring is adapted to the outer diameter of the slide rod, and the circumference of the rubber ring is integrally formed with a plurality of circular holes for accommodating the L-shaped rod.

[0018] 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.

[0019] Please see Figures 1-4This utility model provides a technical solution: an aluminum flexible tube end forming device, including a tail-folding machine 1. The tail-folding machine 1 is existing technology. During use, the operator manually presses down the lever handle of the tail-folding machine, amplifying the force using the lever principle, driving the upper mold assembly to move towards the tail of the aluminum tube. The upper and lower molds cooperate to fold the tail of the aluminum tube, causing plastic deformation. Side plates 2 are fixedly installed on the left and right sides of the tail-folding machine 1, and a pair of sliding rods 3 are fixedly installed between the two side plates 2. The side walls of the side plates 2 have sliding holes for accommodating the sliding rods 3. The two ends of the sliding rods 3 are locked between the side plates 2 by nuts. The spacing of the sliding rods 3 can be easily adjusted or components replaced by removing the nuts, balancing structural stability and flexibility for later maintenance. The sliding rods 3 are equipped with several limiting components that can slide and adjust their position along their length. The spacing between two limiting components can be adjusted to match the outer diameter of the aluminum flexible tube to be processed, thereby guiding and limiting the aluminum flexible tube. The spacing between the two limiting components provides radial constraint on the aluminum tube. Before the aluminum tube enters the processing station of the folding machine 1, continuous guiding and limiting action prevents it from shifting or tilting due to its own weight or processing impact. This precise positioning ensures the alignment of the aluminum tube tail with the folding mold, reducing dimensional deviations, wrinkles, or poor sealing during the folding process, and directly improving product processing accuracy and consistency.

[0020] The limiting component includes a sliding sleeve 4 slidably mounted on the slide rod 3. The outer wall of the sliding sleeve 4 is integrally formed with a hollow cylindrical structure, in which a vertical rod 5 is threadedly installed. This design facilitates the assembly and disassembly of the vertical rod 5. Several L-shaped rods 8 are slidably mounted on the inner wall of the sliding sleeve 4 in a circumferential arrangement. One end of each L-shaped rod 8 is fitted with a rubber ring 7. The inner diameter of the rubber ring 7 matches the outer diameter of the slide rod 3. Several circular holes for accommodating the L-shaped rods 8 are integrally formed on the periphery of the rubber ring 7. An adjusting sleeve 6 is rotatably mounted on the inner wall of the sliding sleeve 4. The adjusting sleeve 6 has arc-shaped holes 9 at corresponding positions to accommodate the L-shaped rods 8. The ends of the L-shaped rods 8 pass through the rubber ring 7 and extend into the arc-shaped holes 9. The outer wall of the adjusting sleeve 6, away from the sliding sleeve 4, has anti-slip ridges to increase friction with the hand and facilitate gripping.

[0021] Working principle: When it is necessary to adjust the position of the limiting component on the slide rod 3, the operator holds the slide sleeve 4 firmly with one hand to prevent it from rotating synchronously with the adjusting sleeve 6, and uses the anti-slip ridge at the end of the adjusting sleeve 6 with the other hand to turn the adjusting sleeve 6, so that the adjusting sleeve 6 rotates relative to the inner wall of the slide sleeve 4. When the adjusting sleeve 6 rotates, the arc-shaped hole 9 on its inner wall rotates synchronously. Due to the curved structure of the arc-shaped hole 9, a radial thrust is generated on the end of the L-shaped rod 8 that extends into the hole, driving the L-shaped rod 8 to extend outward along the inner wall of the slide sleeve 4. When the L-shaped rod 8 extends outward, it simultaneously drives the rubber ring 7 sleeved on its body to expand in diameter, so that the inner diameter of the rubber ring 7 increases and moves away from the outer wall of the slide rod 3. The original clamping force disappears, the constraint between the slide sleeve 4 and the slide rod 3 is released, and the position can be adjusted freely along the length direction of the slide rod 3.

[0022] After adjusting to the designated position, the operator loosens the adjusting sleeve 6, and the rubber ring 7 begins to contract due to its own elasticity, generating an inward pulling force on the L-shaped rod 8, driving the L-shaped rod 8 to slide inward along the inner wall of the sliding sleeve 4 until the end of the L-shaped rod 8 re-fits the inner end of the arc-shaped hole 9. At this time, the rubber ring 7 fits against the outer wall of the sliding rod 3, forming a clamping force to constrain the position of the sliding sleeve 4 on the sliding rod 3.

[0023] This application involves installing a limiting component on one side of the folding machine 1, aligned with the folding station of the aluminum flexible tube. The distance between the two limiting components can be flexibly adjusted according to the outer diameter of the aluminum tube to be processed, forming a continuous and stable guiding and limiting space for the aluminum tube. This precise positioning ensures the alignment of the aluminum tube tail with the folding mold, guaranteeing the alignment accuracy of subsequent folding forming, reducing processing errors caused by aluminum tube misalignment, and thus improving the quality stability of the aluminum flexible tube's end closing.
