Description

Technical Field

[0001] This utility model relates to the technical field of metal decorative parts storage and transportation equipment, and in particular to a multi-layer packaging trolley for metal decorative parts. Background Technology

[0002] Metal decorative parts (whose surfaces are often polished, coated, or otherwise precision-treated) need to go through warehousing and transfer to the assembly site after production. Current packaging and transfer methods usually use single-layer turnover boxes or flatbed trolleys. A single trolley can usually only hold 1-2 layers of decorative parts, and 100 decorative parts require 10-20 trolleys. The workshop storage area exceeds 20 square meters, resulting in serious space waste. In addition, the traditional method uses plastic or wooden turnover boxes, which are difficult to effectively reduce their space by folding when not in use. They need to be stored and recycled in a separate area, further increasing the space occupied and cost. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a multi-layer packaging trolley for metal decorative parts. The specific technical solution is as follows: A multi-layer packaging trolley for metal decorative parts includes a frame with multiple multi-layer placement mesh panels arranged vertically at intervals. One side of each multi-layer placement mesh panel is rotatably connected to the frame via a damping pivot. A limiting component connects the multi-layer placement mesh panel and the frame. The limiting component includes a first connecting ring block and a spring. The first connecting ring block is fixedly connected to the frame. One end of the spring is movably connected to the first connecting ring block via a second connecting ring block. The other end of the spring is connected to a pulling ring block. The multi-layer placement mesh panel has an actuating ring block on the side near the spring, and the actuating ring block is movably connected to the pulling ring block.

[0004] Preferably, each of the layered mesh panels has a support column on the side of its bottom away from the limiting member. When multiple layered mesh panels are unfolded, the lower layered mesh panel supports the upper layered mesh panel on top of it through the support column.

[0005] Preferably, the cross-sectional area of ​​the frame is L-shaped, a hook is hinged to one side of the bottom of the frame, and a traction column is connected to the side of the bottom of the frame away from the hook. The hook can be hooked into the traction column, so that multiple frames can be connected together, making it convenient to pull multiple frames together.

[0006] Preferably, the frame is equipped with four wheels at the bottom corners, which are shock-absorbing.

[0007] Preferably, the multi-layer placement mesh is mesh-like, with the mesh being a metal mesh with a length and width of 10cm.

[0008] The beneficial effects of this utility model are: 1. Improved space utilization: 5-8 layers of stackable mesh panels, a single trolley can hold 50-80 decorative pieces, and only 2 trolleys are needed for 100 decorative pieces. The storage area is reduced from 20㎡ to 3㎡, reducing space occupation; when not in use, they can be stacked for storage, further saving space.

[0009] 2. Reduced labor costs: No need for turnover boxes, decorative parts can be placed directly on the mesh panels, eliminating the steps of loading and unloading boxes; multiple units working together to transport reduce the number of forklift trips, improve per capita efficiency, and reduce the number of workers per transfer from 3 to 1, saving labor costs.

[0010] 3. Reduced turnover costs: Replacing traditional turnover boxes, it can be folded to reduce its own space when not in use, and there is no need for recycling storage area, further optimizing the workshop footprint.

[0011] 4. Improved transfer efficiency: Through the linkage structure of "hook-traction column", 5-10 trolleys can be pulled in batches, and the transportation efficiency is increased from 3-5 units / hour to 15-20 units / hour, shortening the long-distance transfer time in the workshop.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] Example A multi-layer packaging trolley for metal-finished decorative parts, please refer to... Figures 1-3It includes a frame 1 assembly, a multi-layer placement assembly, a limiting and buffering assembly, a trolley linkage assembly, and a moving assembly. The frame 1 assembly provides a stable frame for multi-layer placement. The main body of the frame 1 has an L-shaped cross-section, with the long side being a vertical support frame and the short side being a bottom horizontal frame. The surface of the frame 1 is coated with anti-rust paint (thickness 60μm) + epoxy primer (thickness 30μm), which is resistant to salt spray corrosion for ≥48 hours and is suitable for humid workshop environments. Transverse reinforcing ribs are welded every 300mm on the inner side of the vertical support frame, and triangular support plates are welded at the four corners of the bottom horizontal frame to ensure that the frame 1 can bear a load of ≥500kg (compatible with the weight of 5-20 layers of decorative parts).

[0016] The multi-layer placement assembly is arranged at intervals along the vertical direction of the frame 1, enabling independent layering of decorative parts. This includes layered mesh panels: 5-20 layers are provided, each layer being a rectangular metal mesh panel with 10cm x 10cm square mesh openings (made of 304 stainless steel, polished surface, Ra≤0.8μm to avoid scratching the surface of the decorative parts). Each layer of mesh panel is rotatably connected to the vertical support frame of the frame 1 via two damping shafts 20 (model DZ-50, torque 10N·m, made of 304 stainless steel). The damping shafts 20 have a slow-rotating function (rotation speed 0.5-1° / s) to prevent the decorative parts from shaking due to rapid rotation of the mesh panels. The four sides of the multi-layer mesh plate 2 are connected with protective guards to prevent the workpiece from falling off the mesh plate. Two support columns 21 are welded to the bottom of each mesh plate on the side away from the damping pivot 20. When the mesh plate is laid out horizontally, the support column 21 of the upper mesh plate just abuts against the top of the protective guard of the lower mesh plate, forming a stable support (bearing capacity ≥80kg / layer) to prevent the mesh plate from sagging and deforming. When folded, the support column 21 flips with the mesh plate without affecting the interlayer bonding.

[0017] The limiting and buffering assembly connects the frame 1 and the multi-layered mesh plate 2 to achieve stable limiting after the mesh plate is folded, and avoids the mesh plate from loosening due to transportation bumps. It includes a first connecting ring block 51, which is fixed to the reinforcing rib of the vertical support frame of the frame 1 by welding (one for each layer of mesh plate, with the height flush with the side of the mesh plate); an annular groove is opened on the inner side of the ring block for movable connection with the second connecting ring block 53.

[0018] The second connecting ring block 53 has an annular protrusion on one side (which matches the annular groove of the first connecting ring block 51). The protrusion is embedded in the groove to form a rotating hinge structure (which can rotate 360° without jamming). The other side is welded with a spring 52 connecting post to fix one end of the spring 52.

[0019] Spring 52 is made of 65Mn spring steel. One end is fixed to the connecting post of the second connecting ring block 53 by welding, and the other end is welded to the pulling ring block. Spring 52 has buffering and reset functions. It provides tension when the mesh plate is folded and extends with the rotation of the mesh plate when unfolded to avoid rigid collision.

[0020] One side of the pull ring block is welded to the spring 52, and a U-shaped groove is opened on the other side. The actuating ring block 22 is welded to the protective edge of the multi-layer mesh plate 2 near the spring 52 and embedded in the U-shaped groove to form a snap-fit ​​sliding structure (it can slide up and down along the U-shaped groove to adapt to the change of the mesh plate flipping angle). When the mesh plate is flipped and folded upward, the pull ring block and the actuating ring block 22 pull each other, and the spring 52 contracts to generate tension, which stabilizes and limits the mesh plate in the folded state (fitting against the frame 1 without shaking).

[0021] The trolley linkage component enables rapid connection and batch transfer of multiple trolleys. It includes a traction column 3, which is fixed to the bottom horizontal frame of the frame 1 away from the hook 4 by welding. The top of the column is provided with an annular slot for attaching the hook 4 of the adjacent trolley.

[0022] The hook 4 is installed on the side of the bottom horizontal frame of the chassis 1 near the towing column 3 via a hinge (model CL209-1, which can be rotated 180°). The hook 4 has an anti-slip protrusion on the inside. After it is hooked into the annular slot of the towing column 3, the protrusion and the slot fit tightly to prevent it from coming off during transportation. A single trolley can be connected to the front and rear trolleys through the "hook 4-towing column 3" structure to achieve batch linkage of 5-10 units, which is suitable for forklifts or towing vehicles to pull at one time.

[0023] The mobile components are installed at the bottom of the frame 1 to enable flexible movement and shock absorption of the trolley. They include 10:4 wheels (one at each of the four corners of the bottom of the frame 1), which are shock-absorbing polyurethane wheels with quiet and wear-resistant properties. The wheel 10 is connected to the bottom of the frame 1 via a wheel frame. A shock-absorbing spring 52 is installed between the wheel frame and the frame 1. The shock-absorbing spring 52 can absorb ground bumps and prevent the decorative parts from being bumped and collided during transportation.

[0024] Working principle When unfolding and placing decorative parts: 1. The operator pushes the trolley to the production station and flips the thousand-layer placement mesh plate 2 one by one (the damping shaft 20 rotates slowly to avoid rapid flipping); 2. When the mesh plate is flipped to a horizontal state, the support column 21 of the lower mesh plate abuts against the edge of the upper mesh plate to form stable support; at the same time, the spring 52 of the limit buffer component extends with the rotation of the mesh plate without rigid pulling; 3. The metal-treated decorative parts are placed smoothly into the mesh plate one by one, with 8-10 pieces per layer. After placement, check whether the decorative parts exceed the range of the mesh plate.

[0025] After being transported to its destination, the trolley linkage is released (the flip hook 4 disengages from the traction column 3), and the operator smoothly removes the decorative piece from the mesh plate, avoiding scratching the surface; after the piece is removed, the mesh plate is folded and stored for future use.

[0026] When folding, after placement, the operator flips the multi-layer placement mesh plate upwards. The action ring 22 slides along the U-shaped groove of the pulling ring, and the spring 52 gradually contracts to generate tension. When the mesh plate is flipped to gradually approach perpendicular contact with the frame 1, the tension of the spring 52 stabilizes and limits the mesh plate (without loosening), thus completing the folding. If multiple vehicles need to be linked, flip the hook 4 of the adjacent vehicles and hook it into the annular slot of the traction column 3 of the previous vehicle (the anti-slip protrusion will lock it in place). After 5-10 vehicles are linked, the traction column 3 of the first vehicle can be pulled by a forklift or tractor to achieve batch transfer.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
