Technical Field
[0001] This utility model relates to the field of packaging devices, specifically to a package-packing combination tool. Background Technology
[0002] In the cotton storage sector, the problem of cotton bale collapse during stacking has long been a technical challenge. Current conventional solutions require dispacking and repackaging collapsed bales. The specific process involves using forklifts or lifting equipment to disassemble the entire stack of bales, replacing the plastic straps on the collapsed bales individually, and then re-stacking them. This technical solution has the following significant drawbacks:
[0003] 1. Low work efficiency: The destacking process requires heavy machinery and at least 3-5 operators, and the processing time for a single cotton bale can be as long as 6-15 days;
[0004] 2. Significant safety hazards: High-altitude unpacking operations are prone to causing cotton bales to fall. According to statistics, from 2019 to 2023, the cotton storage industry in my country suffered an average annual direct economic loss of 12 million yuan due to such accidents.
[0005] 3. Site limitations: Depalletizing operations require an additional 30%-50% of the warehouse area as a transit zone, which is difficult to implement when the warehouse capacity is saturated.
[0006] Existing technologies cannot meet the development requirements of modern cotton storage industry in terms of practicality, safety, and economy. Summary of the Invention
[0007] The purpose of this utility model is to overcome the defects and deficiencies of the existing technology and provide a collapsible bale packing combination tool. This collapsible bale packing combination tool can realize in-situ repair on the stack, improve the efficiency of repacking cotton bales after collapsing, reduce safety hazards, and remove the restrictions on site conditions.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] A packing and unpacking assembly tool includes multiple packing and unpacking anchors, an actuator, and a restraint strap.
[0010] The collapsible anchoring device includes a hollow rod, a hook, and a connecting joint. The hook is hinged to the middle section of the hollow rod via a first hinge assembly, and the connecting joint is hinged to the end of the hollow rod via a second hinge assembly. The hook is provided with an inclined surface.
[0011] The hollow rod body has an axial guide channel inside its cavity. The actuating rod can slide through the axial guide channel. Its end engages with the inclined surface of the hook, which can drive the hook to make radial unfolding motion around the hinge axis of the hinge assembly.
[0012] The restraint band is connected to the ends of at least two packing anchors via connecting joints, thereby forming a restraint with the claws on the packing material to be clamped.
[0013] As a preferred embodiment, the hollow rod body has a hook hinge groove in the middle section, and the hinge end of the hook is embedded in the hook hinge groove.
[0014] The hollow rod body has first shaft holes on both sides of the hook hinge slot, and the hinge end of the hook has a second shaft hole that matches the first shaft hole.
[0015] The first hinge assembly includes a first hinge shaft passing through a first shaft hole and a second shaft hole, and a first axial limiting member thereof. The first hinge shaft and the first axial limiting member form a detachable constraint fit.
[0016] As a preferred embodiment, the free end of the hook has a clamping tip, and the included angle of the clamping tip is an acute angle θ, where 5°≤θ≤15°.
[0017] As a preferred embodiment, after the hook is extended, the position of the clamping tip forms a distance L with the end of the hollow rod, where 0.3D≤L≤0.6D, and D is the thickness of the material package to be clamped.
[0018] As a preferred embodiment, the connecting joint is a U-shaped buckle with a third shaft hole at its end, and the end sidewall of the hollow rod is symmetrically provided with a fourth shaft hole;
[0019] The second hinge assembly includes a second hinge shaft passing through a third shaft hole and a fourth shaft hole, and a second axial limiting member disposed at the end of the second hinge shaft. The second axial limiting member and the end of the second hinge shaft form a detachable locking fit.
[0020] As a preferred embodiment, the U-shaped buckle is provided with a binding reinforcement structure between its arms. The binding reinforcement structure includes a transverse positioning rod parallel to the axis of the pivot shaft, and its outer surface is provided with an anti-detachment structure.
[0021] As a preferred embodiment, the hollow rod body adopts a modular segmented structure, including at least two axially connected segmented rod bodies, and the connecting ends of adjacent segmented rod bodies are respectively provided with mutually cooperating helical joints;
[0022] The spiral joint includes an external thread on the first segment rod and an internal thread in the second segment cavity.
[0023] In summary, this utility model has the following advantages:
[0024] 1. This utility model is small in size and can be operated in the narrow gaps between cotton bales, achieving the effect of repackaging directly on the stack of cotton bales. It can repair cotton bales that have broken in place without having to dismantle and stack them back, saving the trouble of using cranes and forklifts. The processing time is reduced from 6-15 days to 15 minutes, saving about 50,000 yuan per work area.
[0025] 2. This utility model is simple to use. Simply insert the packing anchor into the cotton pack seam, push the actuator rod to open the hook, fasten the U-shaped connecting joint, and pull the restraint strap to complete the packing. Even a novice can learn it after watching it once. No special training is required, saving training time.
[0026] 3. The gripping tip of the hook of this utility model is designed at a 5-15 degree angle, like a sewing needle, to poke into the cotton bag, which can greatly reduce damage to the cotton inside the cotton bag.
[0027] 4. After the hook of this utility model is unfolded, the position of the clamping tip is between 0.3D and 0.6D from the end of the hollow rod. The end of the hollow rod abuts against other cotton bags or walls, which can prevent the cotton bags from deforming.
[0028] 5. The hook and connecting joint of this utility model are detachably installed on the hollow rod body through the first hinge assembly and the second hinge assembly, respectively. The parts are easy to replace, the maintenance cost is reduced, and the same set of tools can be used repeatedly.
[0029] 6. With the collapsible packing combination tool of this utility model, when the problem of collapsing cotton bales occurs, there is no need to clear space to dismantle the stacks or prepare additional storage points for the dismantled cotton bales.
[0030] 7. With the collapsible packing combination tool of this utility model, when repacking cotton bales that have collapsed, there is no need to climb high to unpack them, thus avoiding the danger of cotton bales falling. Attached Figure Description

[0047] In this embodiment, the material to be clamped is a cotton bag with a thickness of 800mm (D=800mm); the hollow rod body is made of galvanized pipe with an outer diameter of 25mm, a wall thickness of 5mm, and a length of 2000mm; the hook is forged from 65Mn spring steel with a thickness of 5mm, and a second shaft hole of Φ6mm is opened at the hinge end, and a clamping tip of 10° (θ=10°) is formed at the end with a tip curvature radius R=2mm; the first hinge shaft is made of Φ6mm stainless steel pin with a length of 40mm, and the first axial limiting component is made of M6 anti-loosening nut.
[0048] A hook hinge groove (60mm long and 5mm wide) is milled 400mm from the end of the hollow rod (L=400mm). A Φ6mm first shaft hole is drilled on both sides of the hinge groove. The hinge end of the hook is inserted into the hinge groove. The second shaft hole is aligned with the first shaft hole. The first hinge shaft is inserted and the first axial limiting component is tightened at both ends.
[0049] like Figures 5 to 7 As shown, the connecting joint is a U-shaped buckle with a third shaft hole at its end, and the end sidewall of the hollow rod is symmetrically provided with a fourth shaft hole; the second hinge assembly includes a second hinge shaft passing through the third shaft hole and the fourth shaft hole, and a second axial limiting member disposed at the end of the second hinge shaft, the second axial limiting member and the end of the second hinge shaft forming a detachable locking fit.
