Description

Technical Field

[0001] The utility model relates to the technical field of stone product manufacturing equipment, in particular to a filling device. Background Art

[0002] During the manufacturing process of stone products such as quartz, ceramics, and rock slabs, it is often necessary to use a filling device to fill the texture cavity of the stone products. The filling effect will directly affect the texture effect of the final stone products in the later stage. For example, when the discharge port of the filling device moves along the texture cavity, it is easy for the size of the discharge port and the texture cavity to not automatically adapt, resulting in uneven filling, filling overflowing the texture cavity, and discontinuous texture filling. In addition, there is no component in the discharge mechanism of the existing filling device to push the discharge, resulting in slow filling efficiency and affecting production efficiency.
