Technical Field

The utility model relates to an equipment technical field for ceramic manufacture especially relates to a pottery rolls mould forming device.

Background

Film Rolling (Tape Rolling) is a plastic forming technique and is suitable for producing sheet-like products with the thickness of less than 1 mm. The basic principle of roll film forming is to add a binder and a plasticizer to a ceramic oxide to produce a thick, soft blank which is then extruded between two rolls to form a film. The diaphragm with proper thickness is obtained by adjusting the distance between the rollers and passing through a plurality of groups of rollers with gradually decreasing distance. The process flow of the rolling film forming comprises five steps of material preparation, material proportioning, rough rolling, finish rolling and cutting. The rough rolling is to mix the blank to coat a layer of adhesive and plasticizer on the surface of the ceramic powder uniformly, and the bubbles in the blank are discharged continuously by continuous extrusion, and the additive is volatilized gradually along with blowing while mixing, thereby forming a thicker film. The finish rolling is to turn the diaphragm by 90 degrees, gradually reduce the distance between the rollers, and roll for a plurality of times, thereby obtaining the film with good density, uniformity, smoothness and thickness. However, in the process of rolling ceramic products, the roller may be oxidized by additives in the ceramic materials, which reduces the service life and affects the formation of the ceramic products. Meanwhile, the existing roller can be replaced, but the replaced roller sleeve is not effectively fixed, so that the phenomenon that the roller sleeve slips when in working is caused, the rolling of a ceramic product is influenced, the roller is damaged due to the fact that vibration is generated when the roller sleeve is rolled, and the service life of the roller is shortened.

To the above situation, for overcoming the defect of prior art, the utility model aims at providing a pottery rolls mould forming device can avoid wholly changing when changing the roll, reduces the cost when using, can also effectually fix the roller shell simultaneously to reduce the influence that its vibrations produced, improve the life of roll.

The ceramic rolling die forming device comprises a rotating shaft, wherein a cylindrical inner core is fixed on the rotating shaft through a pin key, the inner core and the rotating shaft are coaxially installed, a plurality of strip-shaped rectangular grooves are formed in the inner core and are parallel to the axis of the inner core, a cylindrical roller sleeve is sleeved on the inner core, the rectangular grooves are uniformly distributed along the circumference of the inner core, a plurality of jacking assemblies are arranged in the rectangular grooves, each jacking assembly comprises a spring positioned in the rectangular groove, the axis of the spring is perpendicular to the axis of the inner core, a jacking block is arranged between the spring and the roller sleeve, one end, far away from the roller sleeve, of the jacking block is fixedly connected with the spring, one end, far away from the jacking block, of the spring is fixed at the bottom of the rectangular groove, two top plates are sleeved on the rotating shaft and are respectively positioned on two sides of the inner core, threads are arranged on two sides of the inner core on the rotating shaft, nuts are arranged on the two sides of the inner core in a threaded, the two nuts are respectively in close contact with the two top plates.

Preferably, be equipped with a plurality of type groove and a plurality of rectangular channel of carving on the inner core and set up at intervals, carve the axis direction setting of type groove along the inner core, be fixed with a plurality of types of carving piece and carve the axis direction setting of type piece along the roller shell on the inner wall of roller shell, carve the type groove and carve the type piece between the setting of mutually supporting.

Preferably, the ejector block is made of rubber, and anti-skid grains are arranged on the inner wall of the roller sleeve.

The utility model has the advantages that: can improve and only change the roller shell, avoid changing whole roll, cost when having reduced the use can produce sufficient stationary force to the roller shell when using, avoids the roller shell to produce and slides, improves production efficiency. Meanwhile, when the roller is used, the vibration generated during working can be well absorbed, and the service life of the roller is prolonged.
