Description

Technical Field

[0001] The present invention relates to the technical field of ceramic forming, in particular to a shaping and manufacturing device for ceramic processing and a method thereof. Background Art

[0002] The production process of daily-use ceramic bowls mainly includes raw material processing, molding, firing and subsequent processing. The raw material is mainly kaolin (containing components such as silica and alumina), which needs to be crushed, screened, and cleaned before being mixed with water to form a slurry. It is then filtered and vacuum-mixed to remove air and improve molding properties.

[0003] Traditional craftsmanship uses manual or mechanical shaping by throwing, and some modern processes have been automated. For example, spin forming can form rotating porcelain, but due to the difficulty of demolding, it is difficult to form a closed-mouthed shape. The closed-mouthed shape generally uses a slip casting mold, but the efficiency of slip casting molds is low, so the forming efficiency of the closed-mouthed shape is low. The formed blank is fired at a high temperature (about 1300℃), and the glaze is fused during firing to form a surface gloss. High-temperature firing can increase the density and hardness of the porcelain, and the final product has a hard texture and good light transmittance.

[0004] The existing molding equipment is difficult to demould and difficult to spin-form the mouth-sealing device. It is necessary to design equipment that is convenient for spinning-forming the mouth-sealing device. Summary of the Invention

[0018] S4: The rotary extrusion system drives the blank to approach the side wall of the forming die, and extrudes the blank toward the forming die;

[0019] S5: The smoothing system drives the blank to approach the side wall of the forming mold, and smoothes the inner side wall of the blank in the forming mold.

[0020] The beneficial effects of the present invention are:

[0021] The multi-station rotary system can be rotatably installed on the frame to convey the forming mold.

[0041] The present invention will be further described below in conjunction with the accompanying drawings:

[0042] like Figure 1 — Figure 9As shown, this embodiment provides a shaping and manufacturing device for ceramic processing, including a blank input system 1, a frame 2, a multi-station rotary system 3, a feeding system 4, a spray lubrication system 5, a rotary extrusion system 6 and a smoothing system 7. The multi-station rotary system 3 is rotatably mounted on the frame 2 to convey a forming mold 32. The multi-station rotary system 3 has a plurality of mold rotary mounting positions 31 for mounting the forming mold 32. The mold rotary mounting position 31 is used to mount the forming mold 32. The feeding system 4, the spray lubrication system 5, the rotary extrusion system 6 and the smoothing system 7 are installed on the frame 2 along the rotation direction of the multi-station rotary system 3, the blank input system 1 is installed on the frame 2 to input the blank 8, the feeding system 4 is installed on the side of the blank input system 1, and the feeding system 4 clamps the blank 8 transported by the blank input system 1 to the mold rotation mounting position 31, and the rotary extrusion system 6 has a spherical forming head 66 adapted to the forming mold 32. The rotary extrusion system 6 drives the spherical forming head 66 to rotate in the forming mold 32, thereby realizing the forming of a narrow-mouthed container in the forming mold 32.

[0043] The forming mold 32 includes a mold base 321, a deflection extrusion device 323 and a blank rotation system 322. The deflection extrusion device 323 includes a rotating block 3231, an elastic sheet 3232 and a deflection motor. The rotating block 3231 is rotatably mounted on the mold base 321. The rotating block 3231 has a forming arc surface 32311. The elastic sheet 3232 is mounted on one side of the forming arc surface 32311 of the rotating block 3231. The deflection motor is mounted on the mold base 321 and is in transmission connection with the rotating block 3231. When the spherical forming head 66 rotates, the spherical forming head 66 gradually drives the blank 8 to be squeezed toward the forming arc surface 32311 of the rotating block 3231, and the forming arc surface 32311 reciprocates and rotates under the drive of the deflection motor. The elastic sheet 3232 gradually adapts to the shape of the forming arc surface 32311. Due to the reciprocating vibration and rotation of the forming arc surface 32311, the spherical forming head 66 pushes the blank 8 close to the forming arc surface 32311, and the blank 8 is repeatedly squeezed and formed. In order to ensure the forming effect, the deflection angle of the deflection motor is 3 degrees to 5 degrees. The deflection frequency of the deflection motor is 60 to 120 times per minute. Due to the repeated extrusion of the elastic sheet 3232, the rapid molding of the blank 8 is facilitated. In order to facilitate the separation of the blank rotation system 322 and the blank 8, the blank rotation system 322 includes a blank turntable 3221, a blank supporting rubber sheet 3222 and a disengagement concave-convex plate 3223. The blank turntable 3221 is mounted on the mold base 321 through a bearing, and the disengagement concave-convex plate 3223 is mounted on the blank turntable 3221. The blank supporting rubber sheet 3222 is mounted on the blank turntable 3221. On the material turntable 3221, the blank supporting rubber sheet 3222 is sealed and covered on the disengagement concave-convex plate 3223. The blank supporting rubber sheet 3222 is sealed and covered between the disengagement concave-convex plates 3223 to form a demolding control cavity. The demolding control cavity is connected to a vacuum pump through a rotary joint. The blank 8 is placed on the blank supporting rubber sheet 3222. When demolding is required, the vacuum pump draws air to make the blank supporting rubber sheet 3222 turn from flat to uneven, thereby making the blank supporting rubber sheet 3222 separate from the molded blank 8, which is convenient for demolding.

The lubricator 51 is installed on the output end of the lubricating elevator 52. The lubricator 51 has a plurality of spray nozzles, which spray water evenly on the inner side wall of the blank 8 of the forming mold 32, forming a water film between the spherical forming head 66 and the blank 8, reducing the adhesion between the spherical forming head 66 and the blank 8, and preventing the entire piece of material on the blank 8 from falling off onto the spherical forming head 66. In order to facilitate the spherical forming head 66 to drive the blank 8 to rotate, the spherical forming head 66 is provided with conventional anti-slip patterns.

[0048] Specifically, the rotary extrusion system 6 includes a rotary elevator 61, a rotary transverse movement module 62, a rotary longitudinal movement module 63, a rotary swing module 64, a forming head rotary module 65 and a spherical forming head 66.

The spherical forming head 66 rotates to extrude the blank 8, and extrude the blank 8 toward the rotating block 3231 of the deflection extrusion device 323, so that the blank 8 is gradually formed.

[0049] Specifically, the smoothing system 7 includes a smoothing elevator 71, a smoothing transverse movement module 72, a smoothing rotary module 73 and a spherical smoothing head 74.

The smoothing elevator 71 is installed on the smoothing transverse movement module 72. The smoothing elevator 71 is a pneumatic lifting device. The smoothing rotary module 73 is installed on the smoothing elevator 71. The smoothing rotary module 73 is clamped with a spherical smoothing head 74.
