Description

Technical Field

[0001] The utility model relates to the technical field of bulk material conveyors, in particular to a constant flow control device for bulk material conveyors. Background Art

[0002] Belt conveyors, also called belt conveyors or rubber belt conveyors, are economical logistics conveying equipment that are indispensable for rhythmic assembly lines. Belt conveyors can be divided into heavy-duty belt conveyors such as mining belt conveyors and light-duty belt conveyors such as those used in electronic plastics, food and light industry, chemical and pharmaceutical industries according to their conveying capacity.

[0003] The Chinese patent publication number CN219601722U discloses a material flow control device for a circular tube belt conveyor, which conveys the packaged material through a belt. When the material moves to one end of the belt, it can fall into the package or packaging box. At the same time, the barrier component is driven to move back and forth by the driving component. When the barrier component moves in one direction, it can act on one side of the belt to intercept the material from the middle of the material. When the barrier component moves in the other direction, it can move away from the belt to release the interception state of the material, so that the material on one side of the belt is distributed at intervals, so that the material can be transported to different packaging bags or packaging boxes to achieve continuous packaging of the material. Compared with the existing technology, it can drive the material to be arranged at intervals on one side of the belt to reserve sufficient time for the replacement of packaging bags or packaging boxes, prevent the material from spilling onto the ground, and ensure that the material can be accurately and continuously transported to the inside of the packaging bag or packaging box, thereby improving the packaging effect of the material.

[0004] The above solution uses a barrier component to block the material on the belt to control the material conveying rate. However, because the limit plate blocks the excess material, it will fall off the belt after accumulation. If it is not handled in time, it will cause serious material loss. To this end, we provide a constant flow control device for bulk material conveyors to solve the above problem. Utility Model Content
