[0019] The present invention will be described in detail below with reference to the accompanying drawings.

[0020] A clay rolling device for producing crystal celadon cups, such as Figure 1-Figure 2 As shown, it includes a base 1 and a bracket 2 fixed on the upper end surface of the base 1, the upper end surface of the base 1 is provided with a rotating block 3 rotatably connected to it, the base 1 is provided with a driving mechanism for driving the rotating block 3 to rotate, and the side wall of the rotating block 3 is provided with a plurality of extension rods 4 distributed in a circular array, and the end of the extension rod 4 away from the rotating block 3 is provided with a placement groove, and a turntable 5 rotatably connected to it is provided in the placement groove, and the lower end surface of the extension rod 4 is provided with a motor 6 for driving the turntable 5 to rotate, and the upper end surface of the turntable 5 is provided with a receiving groove, and a lower mold base 7 is placed in the receiving groove, and the lower end surface of the lower mold base 7 is fixedly connected with a protrusion, and the inner wall notch of the receiving groove is provided with a card slot for the protrusion to be inserted into. When the lower mold base 7 is placed in the receiving groove, the card block will also be inserted into the card slot, so that the turntable 5 can rotate with the lower mold base 7.

[0021] The driving mechanism includes a worm gear 9 rotatably connected to the base 1, a fixed block fixedly connected to the upper end surface of the base 1, a worm 10 rotatably connected to the fixed block and meshing with the worm gear 9, and a second motor for driving the worm 10 to rotate is installed on the fixed block. The second motor is a servo motor, and the output shaft of the second motor is transmission-connected to one end of the worm 10.

[0022] A rolling head 8 is provided on the bracket 2, and a lifting mechanism for driving the rolling head 8 to rise and fall is provided on the bracket 2. The lifting mechanism includes a mounting frame 11 fixedly connected to the upper end face of the bracket 2, and a motor three 12 is installed on the mounting frame 11. The output shaft of the motor three 12 is provided with a screw rod 13 with one end fixedly connected thereto, and the other end of the screw rod 13 is rotatably connected to the upper end face of the bracket 2. A nut seat 14 is sleeved on the screw rod 13, and the lower end face of the nut seat 14 is fixedly connected to a connecting rod 15. A through hole is opened on the bracket 2 for the connecting rod 15 to pass through, and one end of the connecting rod 15 passing through the through hole is fixedly connected to a movable plate 16, and the rolling head 8 is fixedly connected to the lower end face of the movable plate 16.

[0023] Two connecting rods 15 are symmetrically arranged, and the two ends of the connecting rods 15 on both sides are fixedly connected to the movable plate 16 and the nut seat 14 respectively. The two connecting rods 15 pass through the corresponding through holes and move up and down to limit the nut seat 14, so that the rolling head 8 is more stable during the lifting process.

[0024] A telescopic rod 17 is fixedly connected to the inner wall of the bracket 2. The telescopic rod 17 is an electric push rod. The output end of the telescopic rod 17 is fixedly connected to the limit block 18. When the telescopic rod 17 is extended, when one of the extension rods 4 is rotated to the lower mold base 7 placed thereon, corresponding to the position of the rolling head 8 above, the side wall of the extension rod 4 on the side of the forward rotation direction will conflict with the limit block 18.

[0025] Working principle: When the celadon cup needs to be rolled and formed, first put the block of clay into each lower die seat 7, and then put the lower die seat 7 into the receiving groove on each turntable 5 one by one. The worm 10 is driven by the motor 2 to rotate, and the worm 10 can drive the worm wheel 9 to rotate, and the worm wheel 9 can drive the brick and the extension rod 4 to rotate. When the first extension rod 4 along the rotation direction rotates to the position corresponding to the rolling head 8, the lower die seat 7 and the clay block on this extension rod 4 will be just located below the rolling head 8 to be added. At the working station, the side wall of the extension rod 4 contacts the limit block 18, so as to position the extension rod 4 more accurately. At this time, the rotation of the motor 2 is stopped, so that the rotating block 3 and the extension rod 4 remain in the current position, and then the motor 3 12 drives the screw rod 13 to rotate, and the screw rod 13 can drive the nut seat 14 to move downward. The nut seat 14 can drive the rolling head 8 to move downward through the connecting rod 15 and the movable plate 16, and press it into the lower die seat 7. The turntable 5 and the lower die seat 7 are driven to rotate by the motor 1 6, and they are squeezed with the extrusion head to realize the rolling molding of the mud blank;

[0026] After the processing of this clay blank is completed, the motor 3 12 drives the screw rod 13 to rotate in the opposite direction, and the screw rod 13 can drive the connecting rod 15 and the movable plate 16 to move upward through the nut seat 14, so that the rolling head 8 is lifted. In the process of lifting, the telescopic rod 17 will be shortened to make the limit block 18 give the extension rod 4 space to continue to rotate. At this time, the motor 2 and the worm gear 9 and worm 10 mechanism drive the rotating block 3 and the extension rod 4 to rotate again, so that the next lower die seat 7 to be processed is rotated to correspond to the rolling head 8, and the rolling head 8 is moved down again. During the next round of rolling processing, the limit block 18 has positioned the next extension rod 4 as the telescopic rod 17 extends again during the continued rotation, and the operator can remove the lower die base 7 and the clay block that have been processed on the previous extension rod 4 that has been rotated away, and replace them with a new lower die base 7 with the clay block. The replacement process is away from the rolling head 8, which is safer. This process is repeated, and during the replacement process, the next round of rolling processing can be carried out at the same time, the continuity of rolling forming is better, and the efficiency of rolling the clay block is improved.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
