How to protect the products in the chute of the product sorting machine
The chute of the commodity sorting machine is mainly designed through six dimensions: material, structure, buffering, speed control, guidance, timing, and operation and maintenance, to reduce product scratching, collision, compression, and falling damage, achieving "gentle sorting and zero cargo damage".

1、 Material and Surface: Reduce Friction and Scratch
1. Low friction smooth inner wall
Mainstream: UHMWPE (high molecular weight polyethylene), modified PP, stainless steel plate
Surface mirror polishing, no burrs, no welds, no sharp edges and corners
Function: The product has low sliding resistance and does not scratch the packaging/surface
2. Inner lining flexible buffer layer (for consumables only)
Stick rubber sheet, silicone pad, EVA foam, velvet cloth, PU soft board
The inner wall of the metal groove is fully covered with soft material to avoid hard contact
3. Splicing without gaps or steps
Smooth transition between segments and sealing of joint filling plates
Prevent soft bags and thin parts from getting stuck and tearing
2、 Structure and slope: speed control+impact protection+anti flying bag
1. Reasonable inclination angle (golden slope)
Conventional: 18 ° -28 °; Fragile/lightweight: 10 ° -22 °
Long chute: steep up and slow down down (upper diversion, lower deceleration)
2. Spiral/curved groove (special for large drop)
Multi layer/high drop spiral groove is used to extend the path and disperse potential energy
Uniform curvature, no sharp turns, avoiding rollover and impact
3. High gear edge+anti flying
Raise the barrier edges on both sides
Set up stoppers, buffer curtains, and speed bumps at the exit to prevent flying out/rebounding
3、 Buffer device (end/critical section): absorbs impact
1. Entrance buffer
Spring steel plate, spring bed, flexible flap at the grid mouth
Flexible reception and no hard impact when entering the product
2. Mid section deceleration/damping
Damping strips, buffering protrusions, corrugated surfaces: progressive deceleration
Unpowered drum and ball bearing section: transforming sliding into rolling, reducing wear and deceleration
3. Export buffer
Rubber curtain, brush curtain, PU rubber strip curtain: gently stop
Horizontal buffer section, stacking section: low-speed basket insertion, no stacking collision
Basket cushion and partition: secondary protection
4、 Speed and timing control: avoid 'violent sorting'
1. Electric control speed regulation (intelligent sliding groove)
Equipped with adjustable speed drum, electric damping, and variable frequency belt
Automatic speed control by weight/size/type
2. The grid timing is correct
The timing difference between the tray/trolley and the grid door is less than 50ms
Late opening of the door can cause injury, early opening can result in missed or falling points
3. Height difference limit
Vertical drop ≤ 800mm (more severe for fragile items)
High score segmentation+multi-level buffering
5、 Special protection adapted to different products
1. Carton/Hard Packaging
Smooth and low friction inner wall, collision barrier, and exit deceleration
2. Soft bags/clothing/shoes
Velvet/silicone lining, no sharp spots, anti snagging and scratch
3. Fragile/Precision/Electronic
Full section buffer lining, spiral descent, low-speed outlet, independent grille
4. Alien/Easy Card Parts
Large rounded corners, wide channels, no gaps, anti jamming structure
6、 Operations and Management: Long term Stable Protection
Regular inspection: worn inner lining, loose retaining edges, aging buffer components
Cleaning: Remove dust/oil stains/tape, prevent slipping/sticking
Classification and usage: Special chute for fragile items, non mixing line
Full grid detection: prevent product stacking, squeezing, and secondary collision
