Description

Technical Field

[0001] This invention relates to the field of clay blank forming technology, and in particular to a rolling mill for processing ceramic blanks. Background Technology

[0002] A ceramic blank rolling mill is a highly efficient plastic forming equipment for clay blanks, mainly used for producing daily-use ceramic products such as bowls, plates, cups, and saucers. Its core principle is to replace the fixed cutting tool in traditional rotary forming with a rotatable rolling head. During operation, the rolling head and the plaster mold containing the clay each rotate in the same direction around their respective axes. The rolling head gradually approaches and rolls and flattens the clay, ultimately forming the blank shape determined by the cavities of both. The rotation axis of the rolling head and the rotation axis of the plaster mold are not parallel, resulting in one end of the rolling head pressing down on the plaster mold while the other end maintains a gap of approximately 5 centimeters between them.

[0003] The core advantage of this technology lies in the high density, high mechanical strength, and resistance to deformation of the formed blank. Due to the rolling contact, the clay is subjected to uniform and gentle stress, resulting in optimized microstructure. Compared to the old process, it significantly improves production efficiency and is easily integrated with upstream and downstream processes to achieve mechanized and automated production. Depending on the product shape (e.g., wide-mouthed and shallow-bellied or narrow-mouthed and deep-bellied), two methods can be used: male die rolling (which determines the outer surface of the blank) or female die rolling (which determines the inner surface of the blank).

[0004] Existing ceramic blank processing rolling machines form the blanks after filling. However, due to reasons such as the deviation of the filler position and the mismatch between the material shape and the mold, the finished product after rolling may have missing corners, which requires filling again to fill the missing corners, thus wasting time. Summary of the Invention

[0005] To overcome the technical defects of the existing technology, the present invention provides a rolling mill for processing ceramic blanks, which reduces waste and has high production efficiency.

[0006] The technical solution adopted in this invention is:

[0007] A ceramic blank processing rolling mill includes a mold rotation system, a mold head rotation system, a mold head motion system, a frame, a blank replenishment system, and a vision system. The mold rotation system is mounted on the frame, and the forming mold is mounted on the mold rotation system. The mold head motion system is slidably mounted on the frame, and the mold head rotation system is mounted above the mold head motion system. The mold head rotation system and the mold rotation system are arranged opposite each other, but their rotation axes are not parallel, resulting in a larger gap at one end and a smaller gap at the other. The blank replenishment system is positioned towards the end of the gap between the mold head rotation system and the mold rotation system. At one end, the blank replenishment system is slidably mounted on the frame, and the vision system is mounted on the frame, pointing towards the mold rotation system. The blank replenishment system includes a replenishment trough, a pelletizing device, and a replenishment motion device. The pelletizing device is mounted on the replenishment motion device and is located above the replenishment trough. The replenishment motion device is slidably mounted on the frame, and the replenishment trough is mounted on the replenishment motion device. The sliding direction of the replenishment motion device points towards the mold rotation system. The pelletizing device includes two rotating pelletizing rollers that are in contact with each other and rotate relative to each other. Each pelletizing roller has a plurality of semi-circular forming grooves at corresponding positions.

[0008] Preferably, the mold rotation system includes a mold rotation motor, a mold tray, and a mold motor bracket. The mold motor bracket is mounted on the frame, the mold rotation motor is mounted on the mold motor bracket, and the mold tray is mounted on the output end of the mold rotation motor.

[0009] Preferably, the mold head rotation system includes an upper mold head and a mold head motor, the upper mold head being mounted on the output end of the mold head motor, and the mold head motor being mounted on the mold head motion system.

[0010] Preferably, the die head motion system includes a die head transverse rail, a die head transverse cylinder, a die head transverse plate, a die lifting plate, and a die head lifting cylinder. The die head transverse rail and the die head transverse cylinder are both mounted on the frame. The die head transverse plate is slidably mounted on the die head transverse rail and is drivenly connected to the die head transverse cylinder. The die lifting plate is slidably mounted on the die head transverse plate in the lifting direction. The die head lifting cylinder is mounted on the die head transverse plate and is drivenly connected to the die lifting plate. The die head rotation system is mounted on the die lifting plate.

[0011] Preferably, the vision system is a vision camera connected to a computer.

[0012] Preferably, the feeding trough is provided with a plurality of pushing air vents, and the feeding trough has a hollow structure.

[0013] Preferably, the cross-section of the feeding trough is semi-circular.

[0014] Preferably, the feeding motion device includes a feeding motion rail, a feeding motion slider, and a feeding motion cylinder. The feeding motion cylinder and the feeding motion rail are both mounted on the frame. The feeding motion slider is slidably mounted on the feeding motion rail. The feeding motion cylinder is drivenly connected to the feeding motion slider. The feeding groove is mounted on the feeding motion slider.

[0015] The beneficial effects of this invention are:

[0016] A mold rotation system is mounted on the frame to achieve the rotation of the forming mold, which is a plaster mold. A mold head motion system is slidably mounted on the frame to achieve the movement of the mold head. The forming mold is placed on the mold rotation system through a pre-set slot. The mold head rotation system is mounted on top of the mold head motion system. The mold head motion system drives the mold head rotation system to move closer to and away from the mold rotation system. The mold head rotation system and the mold rotation system are arranged opposite to each other and rotate in the same direction, so that the material is formed in the forming mold. The rotation axis of the mold head rotation system and the rotation axis of the mold rotation system are not parallel, so the distance between the mold head rotation system and the mold rotation system is large at one end and small at the other end. The blank replenishment system points to the end with the larger distance between the mold head rotation system and the mold rotation system, so as to replenish the blank in the forming mold when a gap occurs. The blank replenishment system is slidably mounted on the frame to achieve the replenishment of the blank when a gap occurs, and the blank replenishment system is withdrawn after replenishment to avoid interference. A vision system is mounted on the frame and points to the mold rotation system.

[0017] The billet replenishment system includes a replenishment trough, a pelletizing device, and a replenishment motion device. The pelletizing device is mounted on the replenishment motion device and is located above the replenishment trough. The replenishment motion device is slidably mounted on the frame, and the replenishment trough is mounted on the replenishment motion device. The sliding direction of the replenishment motion device is towards the mold rotation system. After the vision system detects a gap in the billet, the replenishment motion device drives the replenishment trough to approach the mold rotation system, and the replenishment trough replenishes material to the mold rotation system, thereby filling the gap in the billet, reducing waste, and increasing production efficiency.

[0018] The pelletizing device includes two rotating pelletizing rollers that are in contact with each other and rotate relative to each other. Each pelletizing roller has a number of semi-circular forming grooves at corresponding positions. When the two pelletizing rollers rotate relative to each other, the strip-shaped blank passes between the two pelletizing rollers and forms a spherical shape in the forming groove. After the blank forms a spherical shape, it falls into the feeding groove under the action of gravity. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figure 1 — Figure 4As shown, this embodiment provides a rolling mill for processing ceramic blanks, including a mold rotation system 1, a mold head rotation system 2, a mold head movement system 3, a frame 4, a blank replenishment system 5, and a vision system. The mold rotation system 1 is mounted on the frame 4 to realize the rotation of the forming mold, which is a plaster mold. The mold head movement system 3 is slidably mounted on the frame 4 to realize the movement of the mold head rotation system 2. The forming mold is placed on the mold rotation system 1 through a preset slot. The mold head rotation system 2 is mounted on the upper side of the mold head movement system 3. The mold head movement system 3 drives the mold head rotation system 2 to move closer to and away from the mold rotation system 1. The mold head rotation system 2 is arranged opposite to the mold rotation system 1. The die head rotation system 2 rotates in the same direction as the mold rotation system 1, causing the material to be formed inside the mold. The rotation axis of the die head rotation system 2 is not parallel to the rotation axis of the mold rotation system 1, resulting in a larger gap at one end and a smaller gap at the other end between the die head rotation system 2 and the mold rotation system 1. The blank replenishment system 5 points towards the end with the larger gap between the die head rotation system 2 and the mold rotation system 1, thereby replenishing the blank in the mold when a gap occurs in the blank. The blank replenishment system 5 is slidably mounted on the frame 4 to replenish the blank when a gap occurs, and to remove the blank replenishment system 5 after replenishment to avoid interference. The vision system is mounted on the frame 4 and points towards the mold rotation system 1.

[0031] Specifically, the billet replenishment system 5 includes a replenishment trough 51, a pelletizing device 53, and a replenishment motion device 52. The pelletizing device 53 is mounted on the replenishment motion device 52 and is located above the replenishment trough 51. The replenishment motion device 52 is slidably mounted on the frame 4. The replenishment trough 51 is mounted on the replenishment motion device 52, and the sliding direction of the replenishment motion device 52 points towards the mold rotation system 1. After the vision system detects the gap in the billet, the replenishment motion device 52 drives the replenishment trough 51 to approach the mold rotation system 1, and the replenishment trough 51 replenishes the mold rotation system 1, thereby filling the gap in the billet, reducing waste, and increasing production efficiency.

[0032] Specifically, the pelletizing device 53 includes two rotating pelletizing rollers 531. The two pelletizing rollers 531 are in contact and rotate relative to each other. Each pelletizing roller 531 has a number of semi-circular forming grooves at corresponding positions. When the two pelletizing rollers 531 rotate relative to each other, the strip-shaped blank passes between the two pelletizing rollers 531 and forms a spherical shape in the forming groove. After the blank forms a spherical shape, it falls into the feeding groove 51 under the action of gravity.

[0033] Specifically, the mold rotation system 1 includes a mold rotation motor 11, a mold tray 12, and a mold motor bracket 13. The mold motor bracket 13 is mounted on the frame 4, the mold rotation motor 11 is mounted on the mold motor bracket 13, and the mold tray 12 is mounted on the output end of the mold rotation motor 11 to realize the rotation of the mold tray 12. The forming mold is placed and mounted on the mold tray 12 through a preset slot.

[0034] Specifically, the mold head rotation system 2 includes an upper mold head 21 and a mold head motor 22. The upper mold head 21 is installed at the output end of the mold head motor 22, and the mold head motor 22 is installed on the mold head motion system 3. The mold head motion system 3 drives the mold head motor 22 to move, and the mold head motor 22 realizes the rotation of the upper mold head 21.

[0035] Specifically, the mold head motion system 3 includes a mold head transverse rail 31, a mold head transverse cylinder 32, a mold head transverse plate 33, a mold lifting plate 34, and a mold head lifting cylinder 35. The mold head transverse rail 31 and the mold head transverse cylinder 32 are both mounted on the frame 4. The mold head transverse plate 33 is slidably mounted on the mold head transverse rail 31 and is connected to the mold head transverse cylinder 32 in a transmission connection. The mold lifting plate 34 is slidably mounted on the mold head transverse plate 33 in the lifting direction. The mold head lifting cylinder 35 is mounted on the mold head transverse plate 33 and is connected to the mold lifting plate 34 in a transmission connection. The mold head rotation system 2 is mounted on the mold lifting plate 34 to realize the transverse movement and lifting of the upper mold head 21.

[0036] Specifically, the vision system is a vision camera connected to a computer. Judging the defects of the workpiece through the vision camera and computer is existing technology and will not be elaborated here. It can detect whether the blank has a gap in time.

[0037] Specifically, the feeding trough 51 is equipped with several pushing air vents 511 to replenish materials. The feeding trough 51 has a hollow structure and is connected to an air pipe. After the vision system detects a gap in the billet, the computer controls the external air pipe to supply air, thereby enabling the pushing air vents 511 to spray air. The airflow generated by the pushing air vents 511 propels the spherical billet to roll along the feeding trough 51.

[0038] Specifically, the cross-section of the feeding trough 51 is semi-circular to reduce resistance to the material and prevent the spherical blanks in the feeding trough 51 from falling out.

[0039] Specifically, the feeding motion device 52 includes a feeding motion rail 521, a feeding motion slider 522, and a feeding motion cylinder. The feeding motion cylinder and the feeding motion rail 521 are both mounted on the frame 4. The feeding motion slider 522 is slidably mounted on the feeding motion rail 521. The feeding trough 51 is mounted on the feeding motion slider 522. The feeding motion cylinder is connected to the feeding motion slider 522 for transmission, thereby realizing the movement of the feeding trough 51.
