Description

Technical Field

[0001] This utility model belongs to the field of quantitative filling technology, specifically relating to a continuous feeding device and a quantitative filling machine. Background Technology

[0002] A quantitative filling machine is an automated device that uses electronic weighing technology to quantitatively package materials. This equipment integrates automatic feeding, filling, bag dropping, and sealing functions, and is equipped with an intelligent control system for automated production. Existing quantitative filling machines mainly consist of a feeding device and a sealing device. The packaging bag is placed at the outlet of the feeding device to complete the filling, and then the bag is conveyed by a conveyor belt to the sealing device for sealing. Subsequent processes include shaping and palletizing. However, existing feeding devices typically include a weighing component and a receiving component. The receiving component receives the material and slowly drops it into the weighing component to ensure stable weighing of the specified quantity. After weighing, the material in the weighing component is filled into the packaging bag. Because weighing can only continue after each filling, continuous filling is not possible, resulting in low filling efficiency.

[0003] Therefore, how to avoid the low filling efficiency caused by weighing only after filling is completed is a technical problem that urgently needs to be solved in this field.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0050] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein.
