Description

Technical Field

[0001] The utility model relates to the technical field of clay embryo cutting equipment, in particular to an automatic clay embryo cutting mechanism, which is mainly used in the production of ceramic products. Background Art

[0002] Clay embryo cutting is an important process in the ceramic production process, which mainly involves cutting the clay material according to a predetermined size and shape. This step is crucial to ensure the quality and specifications of the final product. When cutting the clay embryo, it is necessary to keep the position of the clay embryo in a stable state to avoid rolling during cutting, resulting in cutting size errors. In the prior art, for example, the clay embryo cutting device disclosed in the utility model patent with publication number CN217144313U and patent name is a clay embryo follower cutting device for the ceramic insulating terminal production industry. In its structure, the clay embryo is placed on a contact block, and the contact block has a C-shape that matches the outer end face of the clay embryo. This structure can only ensure that the clay embryo matching the C-shape size of the contact block is in a stable state. When the outer diameter of the clay embryo is smaller than the C-shape radius of the contact block, the clay embryo is prone to rolling, resulting in a skewed cutting position. When the outer diameter of the clay embryo is larger than the C-shape radius of the contact block, the clay embryo contour is easily deformed during cutting and extrusion. As can be seen from the above, the cutting mechanism can only be applied to the cutting of a single-size clay embryo, and is not compatible with clay embryos of different diameters, and its scope of use is limited.

[0033] Working principle:

[0034] This automatic mud embryo cutting mechanism is placed at the mud embryo outlet. After the mud embryo is discharged, the follower belt carries the mud embryo. When the mud embryo is extruded to a specified length, the mechanism receives a cutting signal, and the pressing cylinder 6.1 of the pressing mechanism 6 drives the pressing plate 6.2 to press the mud embryo. At this time, the cutting mechanism 3 moves with the mud embryo under the drive of the slider of the follower mechanism 4.

At this time, the pressing cylinder 6.1 drives the pressing plate 6.2 to retreat. The mechanism is compatible with the cutting of mud embryos with a diameter of 500-800mm. The scale pointer 6.10 on the pressing beam 7.3 corresponds to the cutting height; the cutting height adjustment method is: first loosen the locking handle 6.8 to allow the pressing guide column 6.3 to slide freely in the beam 7.3; turn the rotating handwheel 6.9 to adjust the height of the pressing mechanism 6 to achieve compatible cutting of mud embryos of different diameters.

The steel wire 3.1 is replaced manually, and the system can operate normally after resetting.
