What are the structural characteristics of the four layer grid groove for small items
The four layer grid chute for small items is the core component of the logistics sorting system, designed specifically for small items (≤ 5kg). Its structural characteristics revolve around three core elements: efficient use of space, stable transportation, and user-friendly operation

1、 Stereoscopic Layered Structure: Space Utilization
Vertical four layer layout: The main body is composed of brackets and four independent compartments stacked vertically, occupying only 1/4 of a single-layer chute with the same width, and increasing space utilization by 300%.
Modular combination: Each layer of chute is independent and detachable, allowing for flexible increase or decrease in the number of layers and adjustment of the number of compartments, adapting to different site and sorting volume requirements.
Ergonomic height: The bottom layer is about 800mm above the ground, and the top layer is about 1600mm. The sorting station can immediately cover the entire layer without frequent bending or lifting of hands.
2、 Slide streamline design: efficient and smooth conveying
1. Three stage functional zoning
Buffer section (inclination angle 25 °~28 °): Reduce speed at a large angle at the entrance to prevent small items from high-speed impact, rolling, and damage.
Self sliding section (inclination angle 10 °~15 °): The middle and rear sections have a gentle slope, combined with a smooth inner wall, allowing the small piece to slide at a constant speed of 1.5~2m/s.
Inventory section: End storage area with soft barriers/cushioning pads to prevent impact damage.
2. Anti jamming and scratch optimization
Tilt angle science: Overall 30 °~45 °, suitable for small piece weight, ensuring that gravity sliding does not cause jamming.
Arc transition: The curve adopts R50~R100mm large rounded corners, without dead corners or jamming.
Smooth inner wall: The surface roughness Ra of the material is less than or equal to 1.6 μ m to prevent scratching and snagging of the package.
Section selection: mostly U-shaped (good support, suitable for irregular parts) or V-shaped (strong guidance, suitable for regular parts).
3、 Material and Specifications: Durable and Suitable for Small Parts
1. Excellent materials
Stainless steel: high strength, wear-resistant and corrosion-resistant, suitable for high-strength and high humidity environments.
Engineering plastics: light weight, low cost, good toughness, can effectively buffer, reduce noise and prevent damage.
Aluminum alloy: combining lightweight and high strength, suitable for scenarios with load-bearing requirements.
2. Standard specifications
Grid width: 150-250mm, suitable for mobile phones, cosmetics, small express delivery, etc. (≤ 200 × 150 × 100mm).
Load capacity: Single grid port usually ≤ 5kg, designed for lightweight small items.
4、 Summary of Core Structural Advantages
Space saving: Vertical four story, small footprint, high density.
High efficiency: Four parallel channels, sorting efficiency is nearly 4 times higher than single-layer.
Low damage: Buffer+smooth slide, damage rate<0.1%.
Easy to operate: Highly user-friendly, reducing the labor intensity of sorting personnel.
Wide adaptability: modular and multi material options, suitable for small item sorting scenarios such as e-commerce, express delivery, medicine, electronics, etc.
