Description

Technical Field

[0001] The utility model belongs to the technical field of feeders, and particularly relates to a single-screw integrated feeder. Background Art

[0002] Single screw volumetric feeders are widely used for various materials, including small balls, granules and materials with good fluidity. Single screw volumetric feeders are generally suitable for materials with good fluidity. They are usually used in the production process of chemicals, paints, greases, medicines, feeds, daily chemicals, food, pharmaceuticals and other products. Because such products often need to be transported to downstream equipment in batches or continuously and stably during production, all parts in contact with the materials are made of stainless steel.

[0003] For example, the Chinese utility model patent with announcement number CN212862955U discloses a single-screw volumetric feeder, including a fixed bottom plate, a support frame fixedly connected to the left side of the top of the fixed bottom plate, a sleeve fixedly connected to the left side of the support frame, a connecting plate fixedly connected to the end of the sleeve away from the support frame, and a fixed frame fixedly connected to the left side of the connecting plate. The single-screw volumetric feeder puts the material into the storage tube by opening the outer cover, and the fixed partition will screen the material so that the material is divided into multiple parts for transportation to prevent excessive material from clogging the connecting tube. The drive motor is started to drive the transmission rod to rotate. During the rotation of the transmission rod, the push rod pushes the material to the right. The transmission rod can be replaced according to the type of material. The feeder is simple and easy to operate, suitable for the production of different materials, improving production efficiency and reducing labor intensity.

[0004] The feeder needs to be cleaned internally after long-term use, otherwise it is easy to cause blockage. The above-mentioned utility model is a closed design that cannot be opened for cleaning, and it is also impossible to filter and feed large-particle powders, which will accumulate and cause blockage in the feeding process.
