Micro Automatic Loader is an automatic granule/powder conveying device supporting small automated production lines. It mainly works by vacuum negative-pressure suction, and there are also micro screw-type and vibrating feeder models. Relying on a material level sensor + microcomputer control, it automatically conveys raw materials from the material barrel to the hoppers of injection molding machines, extruders, roll coaters and packaging machines, achieving unattended automatic feeding.

Vacuum main unit (blower / vacuum generator), stainless steel hopper, suction hose, photoelectric material level sensor, filter element, pulse reverse-jet dust cleaning device, microcomputer controller, illuminated button switch, quick-release clamp.
Performance Features
1. **Compact Size, Small Footprint, Flexible Installation**
The whole machine is lightweight with a vertical compact structure; it can be mounted directly above the equipment hopper without occupying workshop floor space. It can be fixed in place, and some models have casters for easy relocation — ideal for narrow workstations.
2. **Fully Automatic Closed-Loop Feeding, Less Manual Loading**
With photoelectric material level detection, suction starts automatically when the hopper is short of material and stops automatically when full, providing continuous cyclic feeding. Parameters are set via microcomputer, allowing suction time and interval cycles to be configured, with no need for frequent manual refilling.
3. **Sealed Conveying, Dust-Free and Pollution-Free**
Materials are conveyed under negative pressure inside pipes, with no dust flying, reducing raw material waste and protecting the workshop environment. Parts in contact with materials are mostly 304 stainless steel, polished and smooth, not prone to material accumulation, easy to clean, and preventing cross-contamination. The filter element has built-in pulse reverse jetting to automatically remove dust from the filter mesh, avoiding clogging.
4. **Simple Control, Complete Safety Protection**
Microcomputer control with a simple operation panel; equipped with **material shortage alarm, overload protection and blockage alarm**, with audible and visual fault indication; can be connected to an external PLC for linkage control with the entire production line.
5. **Wide Material Adaptability, Easy Material Changeover**
Can convey plastic pellets, small granular materials, powders, small pills and food granules; quick-release hopper and piping make disassembly and cleaning easy, allowing fast switching between different materials.
6. **Low Energy Consumption, Simple Maintenance**
The micro blower has low power and low electricity consumption; few moving parts mean a low failure rate; only regular cleaning of the filter element and hopper is required.
