Description

Technical Field

[0001] The utility model relates to the technical field of ceramic production, in particular to a quantitative feeding device for ceramic raw materials. Background Art

[0002] Ceramic raw materials are materials used to make ceramic products, mainly composed of porcelain clay, mineral powder and porcelain glaze raw materials, etc., and are used in the process of making ceramics. Before making ceramics, the added raw materials need to be quantitatively weighed, and then added after weighing, so as to ensure that the added weight is accurate and stable.

[0003] To this end, the patent with publication number CN220179733U discloses a ceramic raw material quantitative feeding device, whose structure includes a storage box, a quantitative structure and a movable frame. The raw materials are poured into the storage box through the feed port, and then the second solenoid valve is opened during use to allow the raw materials to be discharged through the discharge port and fall into the collection box. Under the action of the rotating shaft, one end of the rocker is forced downward, while the other end is forced upward to apply an extrusion force to the pressure sensor, so that when the raw materials received in the collection box reach the set weight, the second solenoid valve is closed and the first solenoid valve is opened, and the raw materials are discharged from the bottom of the collection box, thereby realizing the quantitative feeding of the raw materials and avoiding the situation where the amount of raw materials added is not properly proportioned, resulting in poor quality of the ceramic raw materials.

[0004] In the above patent, after adding the ceramic raw materials into the collection box, the collection box rotates downward under the action of weight, causing the seesaw to rotate around the rotation axis and the other end to tilt up. The other end of the seesaw squeezes the pressure sensor, thereby realizing the detection of the weight of the ceramic raw materials inside the collection box. Although the above method can realize the detection of the weight of the ceramic raw materials, the pressure is not evenly transmitted to the pressure sensor by tilting the end of the seesaw and squeezing the pressure sensor, and the weighing accuracy needs to be improved.
