Description

Technical Field

[0001] The utility model relates to the technical field of filling, in particular to a curing agent filling mechanism. Background Art

[0002] During the production process of curing agent, a filling machine is required to fill it into a plastic barrel. During filling, the plastic barrel is conveyed to the bottom of the filling machine by a conveyor belt. After the plastic barrel moves to the bottom of the filling machine, the curing agent can be filled into the plastic barrel through a filling tube. After searching, there are many improved technologies for filling. For example, Chinese patent CN219526234U discloses a filling machine for curing agent production, which is provided with a motion structure to make the filling tube swing quickly, and then the curing agent in the filling tube is quickly thrown into the plastic barrel, preventing the curing agent from dripping onto the conveyor belt, thereby increasing the production speed.

[0003] The above prior art has the problem that before filling the plastic barrel with curing agent, the filling tube needs to be inserted into the plastic barrel, but since the height of the filling tube is fixed, it is inconvenient to put the filling tube into the plastic barrel; and after filling, the filling tube needs to be driven by a driving motor to swing to throw out the residual liquid, but since it takes a certain amount of time to swing the filling tube to throw out the residual liquid inside, it is quite time-consuming. Therefore, a curing agent filling mechanism with automatic circulation and sealing of the filling tube is provided to solve the above problems. Utility Model Content

The middle part of the fixed disk 9 is slidably connected to the guide rod 10. The guide rod 10 is located at one end of the bottom of the fixed disk 9 and is fixedly connected to the movable disk 11.
