Description

Technical Field

[0001] The utility model relates to the technical field of feeding machines, in particular to a single-screw metering feeder. Background Art

[0002] The single-screw feeder is a device based on the principle of volumetric separation, mainly used for continuous and intermittent feeding of materials. The single-screw feeder drives and transports the materials from the silo to the designated discharge port through the rotation of the spiral blade to achieve the feeding function. In this process, the rotation speed and volume ratio of the spiral blade determine the average and accuracy of feeding.

[0003] The current feeder design incorporates a funnel structure to simplify and accelerate the feeding process. However, in actual operation, we noticed an urgent problem to be solved: when the materials flow towards the discharge port, they are prone to accumulate and form blockages here, thus affecting the smooth operation of the entire feeding system. In addition, materials are likely to adhere to the inner wall of the funnel, which not only increases the difficulty of cleaning work, but also brings inconvenience to the staff, affecting the overall efficiency and experience of the operation.
