Description

TECHNICAL FIELD

[0001] The application relates to the technical field, and particularly relates to a clay kneading equipment for ceramic production. BACKGROUND

[0002] At present, the clay for ceramic processing is mainly made of natural clay and various natural minerals, and the clay needs to be kneaded before being used for the processing of ceramic wares. The existing clay kneading processing adopts a mechanical vacuum kneading method. The vacuum kneading machine has the advantages of saving labor, time and effort, and can greatly improve the production efficiency of clay kneading. However, the clay prepared by the vacuum kneading machine is almost equal in size after being broken by a Raymond mill through high-speed rotation, and then being stirred by the kneading machine, so that the particles are arranged in a certain direction, and the clay contains stress. The stress is released during high-temperature sintering, so that the parts of the blank shrink unevenly, thereby increasing the shrinkage and deformation rate of the product. Under the same sintering conditions, although the surface is smooth, the water absorption rate and the porosity rate are obviously reduced, which affects the artistic effect and the practical function.

[0003] Compared with the mechanical vacuum kneading, the manual kneading adopts the kneading and knocking method, the specific gravity of the clay is small, the porosity of the blank is large, and the shrinkage and deformation rate of the product after sintering is small. The prepared clay has different particle sizes, and the volume shrinkage after sintering is not uniform. The coarse particles on the surface are slightly protruding, and the inner wall is loose due to the mineral composition of the clay and the accumulation of the clay, so that the clay has a certain porosity and water absorption rate. The clay prepared by manual kneading has a loose structure, a natural state and a good texture effect on the surface, and can better reflect the essence and characteristics of purple sand. The water absorption of the teapot and the natural structure directly affect the practical function. Therefore, in recent years, some high-end purple sand works have returned to the original manual kneading of the material. The traditional manual kneading process is slow, the manual operation link of part of the kneading process is complex, and the physical strength of the workers is required. These factors affect the yield of the purple sand works, and the traditional manual kneading process is complex, which affects the inheritance and is not conducive to the protection of the traditional cultural heritage.

[0031] The working principle of the embodiment is as follows:

[0032] When the clay is put into the bottom of the roller 4 by opening the sealing cover 6, the extension rods on the fixing frame 7 are started to drive the knocking blocks 9 at the bottom to beat the clay, and the clay is extruded and exhausted. The knocking blocks 9 are driven by the independent extension cylinders 8, and the beating force can be adjusted in different areas, so that the stress size and direction of different areas of the clay are different when the clay is beaten, so as to better simulate the state of manual clay beating, prevent the stress caused by the directional arrangement of the clay particles, and reduce the shrinkage and deformation rate of the product.

At this time, the motor 14 is started to drive the first rubbing plate 11 and the second rubbing plate 12 to rotate, so as to rub the clay, instead of the purpose of repeatedly beating and changing the rubbing angle of the clay in the manual clay beating process, and the scattered clay is rubbed and gathered into a clay ball again. Finally, the piston rod of the hydraulic cylinder 18 is retracted to drive the fixing frame 7 to move into the storage groove 17, and the baffle 16 is away from the bottom of the limiting plate 10, so that the clay ball falls under the gravity and falls into the bottom of the roller 4 for beating work again. The clay is repeatedly beaten and rubbed to completely simulate the process of manual clay beating.
