Description

Novel powder weightlessness feeding machine

Technical Field

The utility model relates to the technical field of feeding devices, in particular to a novel powder weightless feeder.

Background

If the feeder is divided into volumetric feeding and weightless feeding according to the material metering mode, the principle of the volumetric feeding is that the materials are continuously brought out from the feeding hopper by the physical and mechanical clearance of the screw grooves and the self weight of the materials under the rotation of the feeding screw; the weightless feeder has a complex structure, and usually comprises a weight sensor and a set of feeding control system, wherein the weight sensor senses the change of materials in unit time and transmits signals to the feeding control system, and the feeding system sends the speed required by a motor to a frequency converter in the form of current signals according to parameters set by an operator, and the frequency converter controls the rotating speed of the feeder.

The weightless feeder is rotated by a single screw or a double screw to forcedly discharge the material out of the feeding hopper. In the production process, when the existing weightless feeder feeds materials for a long time, the materials are piled up in a hopper, some materials can be adhered together even on the wall of the feeding cylinder and the feeding screw under the continuous rotation drive of the feeding screw, and the accumulated materials are more and more, so that the feeding capacity of the feeding screw is poorer and worse, the rotating speed of the feeder is possibly caused to be higher and higher until the machine cannot bear to alarm and stop, or the screw idles, and the machine also alarms and stops. Sudden stop in the feeding process is dangerous, and can possibly cause locking stop of the extruder, and serious scrapping of the whole screw and the machine barrel can possibly cause great loss to companies. This happens sometimes, and only the worker can be added beside the feeder to check the feeding condition, and if necessary, the machine is stopped, thus seriously affecting the efficiency and the product quality.
