Description

Technical Field

[0001] The invention relates to the technical field of screw feeders, in particular to a screw feeder which is convenient for automatic material distribution. Background Art

[0002] In modern industrial production, material transportation and material distribution are indispensable links in many industries. Traditional material handling often relies on multiple fixed screw feeders, which has many disadvantages. With the continuous expansion of production scale and the increasing requirements for production efficiency and cost control, enterprises are facing severe challenges in material transportation and material distribution operations.

[0003] In the patent application with publication number CN208554987U, publication date 2019-03-01, and titled "A Screw Feeder with Automatic Material Distribution", a multi-stage screening box is provided, and a screening net with different meshes is provided in the multi-stage screening box. The size of the material is screened in a fixed interval by using a filter net, and then the screening rate is increased by vibrating the vibration device; after the screening is completed, the filter net is rotated by a descending device, so that the material falls into the receiving box, and then enters the corresponding screw feeder along the guide pipe; however, the layout of setting up multiple groups of screw feeders lacks flexibility and is difficult to quickly adapt to different material specifications and output changes. When the material specifications or output fluctuate, it is easy for some screw feeders to be idle while other feeders are overloaded, resulting in uneven resource allocation and waste, and manual intervention to adjust the material distribution process is not only cumbersome and error-prone, but also reduces production efficiency. At the same time, the purchase cost of multiple sets of screw feeders is high. The numerous equipment bodies and supporting components have greatly increased the procurement budget. In addition, the subsequent maintenance work is complicated, involving the replacement, repair and debugging of parts of multiple equipment, further increasing the company's operating cost burden.
