Description

Technical Field

[0001] The utility model relates to the technical field of screw feeding equipment, in particular to an interrupted screw feeding device. Background Technique

[0002] The conveying of materials is a crucial link and requires the assistance of a screw feeding device. A screw feeding device disclosed in a Chinese patent with the publication number CN207351203U includes a driving component, a transmission component, and a screw feeding rod. The transmission component has a first pivot axis and a second pivot axis, and the first pivot axis and the second pivot axis are located on different parallel straight lines. The transmission component rotates around the second pivot axis. The screw feeding rod has a third pivot axis, and the third pivot axis is located on the same straight line as the first pivot axis. The screw feeding rod is connected to the transmission component, and the end of the screw feeding rod is connected to the power output end of the driving component. By connecting the screw feeding rod to the transmission component and using the non-collinear arrangement of the third pivot axis of the screw feeding rod and the second pivot axis of the transmission component, the transmission component can drive the screw feeding rod to rotate around the second pivot axis, thereby forming a lifting stroke and realizing the automatic lifting function of the screw feeding rod, and the lifting is stable and synchronous, improving the working efficiency of the screw feeding device.

[0003] In actual use, it is found that the opening of the screw feeding device lacks a closing structure. When it is necessary to interrupt the materials, under the action of inertia, the screw push plate will push out some materials, and there is a problem that it is not convenient to interrupt the conveying of materials. Therefore, we propose an interrupted screw feeding device to solve the above problems. Content of the Utility Model
