How to prevent small items from getting stuck, rolling, and stacking in the four layer grid groove
The jamming, rolling, and stacking blockage of the four layer grid groove for small items are mainly caused by the unreasonable angle of the groove, excessive cross-sectional width, unstable center of gravity of the material, protruding joints, and lack of diversion limit. The structural design is carried out from multiple dimensions, including cross-sectional structure, groove inclination angle,
The jamming, rolling, and stacking blockage of the four layer grid groove for small items are mainly caused by the unreasonable angle of the groove, excessive cross-sectional width, unstable center of gravity of the material, protruding joints, and lack of diversion limit. The structural design is carried out from multiple dimensions, including cross-sectional structure, groove inclination angle, diversion limit, joint treatment, anti stacking structure, surface treatment, and layered anti jumping design
1. Adaptation design of slide section width
The effective width of the slide is set according to the external dimensions of the sorting small items, and should not be too wide. A reasonable gap should be reserved on one side of the material to avoid large lateral displacement and overturning of small items inside the slide; If the width is too small, it is easy to get stuck. For irregularly shaped small parts, the bottom plate of the chute is equipped with a central guide rib to constrain the material's walking trajectory, forcing it to slide down along the centerline of the chute and reducing rolling.
2. Reasonably design the inclination angle of the slide and support fine-tuning
The inclination angle of the slide is determined based on the self weight and friction coefficient of the material. If the angle is too small, the material will not slide smoothly and may easily stagnate and accumulate; The angle is too large and the material slides down too quickly, causing it to rebound and roll after hitting the edge. The sliding groove bracket is equipped with an angle adjustment mechanism, which can adjust the inclination angle on site to ensure that the material slides steadily and uniformly under its own weight, without slipping or bouncing at high speed.
3. Set up continuous blocking edges and anti bounce limit structures
Integrated raised barriers are installed on both sides of the chute to prevent small items from bouncing and flying out; The inner side of the barrier is smooth without any protrusions. Add buffer deflectors to the upper and lower material dropping positions of the multi-layer chute. When the upper material falls, it is buffered and guided by the deflectors to avoid direct impact on the lower chute, causing material stacking, rolling, and disorder.
4. Smooth treatment of groove splicing joints
The segmented assembly position of the chute should have a smooth transition with overlapping joints, and the height difference of the joints should be strictly controlled to eliminate steps and burrs. The bottom plate splicing adopts downstream overlapping (upstream plate pressing downstream plate) to prevent reverse flow from hooking packaging bags and irregular small pieces on the steps, and to avoid material jamming.
5. Segmented gentle slopes and energy dissipation structures to prevent material stacking
The long chute can be equipped with multiple gentle slope structures to avoid long-distance acceleration; Install low deceleration bars and curved buffer sections as needed in the slide to reduce the impact of material sliding. Set up a limit plate at the feeding position of the grid to control the quantity of materials to be dropped at a time and prevent the stacking of materials in front and behind during continuous feeding.
6. Grinding reduction treatment on the surface of the bottom plate
The bottom plate of the sliding groove is made of low friction and wear-resistant plate, with a smooth and flat surface, reducing sliding resistance and preventing the accumulation of materials due to the adhesion of lightweight flat parts to the bottom plate; At the same time, the surface should not be too slippery to avoid accelerated rolling of materials. The board has no pits or scratches, reducing the risk of hooking.
7. Bottom maintenance and cleaning structure
Reserve maintenance and cleaning ports at the end or middle of each sliding groove, which can be quickly cleaned in case of blockage; The discharge port at the end of the chute is designed with an expanded flow guide, and the closing position is chamfered to eliminate sharp edges and prevent small parts from getting stuck in the discharge port.
8. Material layer isolation and interlayer interference prevention
The four independent sliding tracks are isolated from each other, and the upper materials will not fall into the lower sliding tracks; Each compartment discharges independently, and materials from different compartments do not interfere with each other, avoiding material mixing caused by multiple compartments falling at the same time.
9. Optimization of anti rolling assistance for irregular parts
For flat parts and small soft packaging items, the bottom plate can be designed with a micro concave U-shaped cross-section, using the two side plates to constrain the material posture and reduce the probability of lateral flipping; There are no exposed bolt heads in the groove, and all fasteners are installed with countersunk holes to prevent protruding bolts from hooking the packaging and causing material jamming.
