Description

Technical Field

[0001] The invention relates to the field of sculpture turntable equipment, in particular to a lifting type ceramic handicraft operating device. Background Art

[0002] Sculpture turntables are used to shape craft sculptures or pottery. Clay is deposited on the turntable's platform, and as the platform rotates, workers can shape the clay into ridges using their hands or tools. The clay blank is shaped from bottom to top during the shaping process. If the blank is tall, the turntable needs to be lowered during the shaping process. This avoids the need for workers to squat or sit down, making it easier for them to shape the blank.

[0003] However, the commonly used liftable sculpture turntables on the market need to be controlled by buttons during the lifting operation. The staff's hands are sticky with a mixture of clay and water. When they touch the buttons, the clay will stick to the buttons. If this happens for a long time, the buttons will be covered with clay, and even the air-dried clay will cause the buttons to jam. Summary of the Invention

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figure 1-Figure 7 The figure shows a lifting type ceramic handicraft operating device, comprising: a device frame 1 and a turntable 7 located above the device frame 1. The outer edge of the turntable 7 is arc-shaped, and the arc edge is bent upward. The bottom of the turntable 7 is concentrically rotated and equipped with a lifting platform 5. The turntable 7 can rotate on the upper end surface of the lifting platform 5. A lifting unit is provided between the lifting platform 5 and the device frame 1. The lifting unit is used to drive the lifting platform 5 to move the turntable 7 up and down.

[0028] It also includes: a rotating unit for driving the turntable 7 to rotate on the upper end surface of the lifting platform 5, and the rotating unit is arranged between the lifting platform 5 and the device frame 1.

[0029] The lifting unit includes a threaded rod 2 that is rotatably assembled inside the device frame 1, and the top threaded sleeve of the threaded rod 2 is provided with an internal threaded sleeve 4, which slides through the device frame 1, and the top of the internal threaded sleeve 4 is concentrically fixed to the bottom of the lifting platform 5. The outer surface of the threaded rod 2 is fixed with a limit gear 3, and the bottom of the lifting platform 5 is fixed with at least two optical axes 6 that are equidistantly distributed around the circumference, and the two optical axes 6 slide through the device frame 1. A driving component and an adjusting component are also provided inside the device frame 1. The driving component is used to drive the limit gear 3 to rotate with the threaded rod 2, and the adjusting component is used to adjust the rotation direction of the limit gear 3 driven by the driving component. The staff can adjust the direction of the driving component through the adjusting component, thereby controlling whether the limit gear 3 rotates with the threaded rod 2, or rotates clockwise or counterclockwise.

[0030] The driving component includes a bracket 11 fixedly mounted inside the device frame 1, and the bracket 11 is located on the outside of the limit gear 3. The internal rotation of the bracket 11 is equipped with a rotating ring 12, and the lower end surface of the rotating ring 12 is fixedly provided with an assembly plate 16. The bottom of the assembly plate 16 is rotatably equipped with two groups of symmetrically distributed first rotating shafts 15 and second rotating shafts 17. The number of each group of first rotating shafts 15 and second rotating shafts 17 is one. The outer surface of each first rotating shaft 15 and second rotating shaft 17 is fixedly sleeved with a third transmission gear 20, and the two third transmission gears 20 distributed on the outer surfaces of the two first rotating shafts 15 are meshed with each other. The outer surface of each first rotating shaft 15 and second rotating shaft 17 is also fixedly sleeved with a first synchronous gear 18, and is located at the same A first synchronous belt 19 is installed between two first synchronous gears 18 of a group. The bottom of the assembly plate 16 is also fixedly provided with an electric motor 13, the output end of the electric motor 13 faces upward, and the output end of the electric motor 13 is fixedly equipped with a drive shaft 21, and the drive shaft 21 is coaxially movable through the rotating ring 12. A second synchronous gear 22 is fixedly sleeved between the upper end surface of one of the first rotating shafts 15 and the outer surface of the drive shaft 21, and a second synchronous belt 23 is installed between the two second synchronous gears 22. The electric motor 13 can drive one of the first rotating shafts 15 to rotate through the drive shaft 21, and under the transmission of the two mutually meshing third transmission gears 20, the other two third transmission gears 20 can rotate synchronously in opposite directions.

[0031] The two first synchronous toothed belts 19 are acute-angled, and the limit gear 3 is distributed between the angle formed by the two first synchronous toothed belts 19. The outer diameter of the first synchronous gear 18 is smaller than the outer diameter of the third transmission gear 20, and the distance between the second rotating shaft 17 and the threaded rod 2 and the center of the rotating ring 12 is consistent, which can ensure that when the assembly plate 16 swings, only the third transmission gear 20 and the limit gear 3 can engage with each other.

[0032] The adjusting component includes a paddle 14 that is slidably fitted on the upper end surface of the bracket 11, and the paddle 14 is fixedly sleeved on the outer surface of the rotating collar 12. The paddle 14 extends out of the device frame 1, and a snap ring 24 is fixedly provided on the end of the paddle 14 away from the rotating collar 12. The snap ring 24 is used for the staff to put the calf or knee into it. The staff can swing the snap ring 24 through the calf or knee, that is, let the rotating collar 12 swing with the assembly plate 16 and the structure at its bottom at the same time.

[0033] The rotating unit includes a first transmission gear 9 which is concentrically fixedly assembled at the bottom of the turntable 7, and the first transmission gear 9 is located between the lifting platform 5 and the turntable 7. The outer side of the lifting platform 5 is rotatably assembled with a sleeve rod 25, and the top of the sleeve rod 25 is concentrically fixedly provided with a second transmission gear 10 which is meshed with the first transmission gear 9. The top of the drive shaft 21 is axially slidably assembled at the bottom of the sleeve rod 25. The drive shaft 21 and the sleeve rod 25 can only telescopically slide, and the drive shaft 21 cannot rotate inside the sleeve rod 25. When the motor 13 is running, it can rotate the second transmission gear 10 through the action of the drive shaft 21 and the sleeve rod 25, so that the first transmission gear 9 rotates with the turntable 7.

[0034] An arc collecting bar 8 is fixedly provided on the lower end surface of the turntable 7, and the arc collecting bar 8 is arc-shaped. The arc-shaped arc collecting bar 8 can receive muddy water flowing down the edge of the turntable 7 to prevent the muddy water from spilling randomly.

[0035] The assembly plate 16 is Y-shaped, and the two forks of the assembly plate 16 are parallel to the two first synchronous belts 19 respectively, which prevents the assembly plate 16 from contacting the limit gear 3 during the swing adjustment process, causing the limit gear 3 to be unable to rotate smoothly.

[0036] Example 2: Please refer to Figure 6 and Figure 7This embodiment is a further explanation of other embodiments. A limiting member is further provided between the paddle 14 and the bracket 11. The limiting member is used to temporarily limit the position state of the paddle 14. The limiting member includes a limiting sleeve 26 fixed to the top of the paddle 14, and a sliding disc 27 is slidably assembled inside the limiting sleeve 26. The sliding disc 27 slides up and down inside the limiting sleeve 26. A dome latch 29 that slides through the paddle 14 is fixed at the lower end of the sliding disc 27, and a spring 28 is fixed between the top of the sliding disc 27 and the limiting sleeve 26. The bottom of the dome latch 29 is dome-shaped. The upper end surface of the bracket 11 is provided with three arc positioning grooves 30 distributed at equal angles around the circumference, and the bottom of the dome pin 29 is slidably assembled with the arc positioning groove 30. The center of the circumferential array of the three arc positioning grooves 30 is the center of the rotating ring 12. Through the engagement of the dome top head of the dome pin 29 with the arc positioning groove 30, under the elastic pressure of the spring 28, the paddle 14 can be elastically limited. When the thrust applied to the paddle 14 is greater than the elastic force of the spring 28, the dome top head of the dome pin 29 will slide out of the arc positioning groove 30, thereby adjusting the position of the paddle 14.

[0037] The radius of the arc positioning groove 30 is consistent with the radius of the dome head of the dome pin 29, and the volume of the arc positioning groove 30 is smaller than the volume of the dome head of the dome pin 29. That is, the arc positioning groove 30 can effectively limit the dome pin 29 while allowing the dome head of the dome pin 29 to slide out from the inside of the arc positioning groove 30 when subjected to a large pushing force.

[0038] Working principle: The staff places the wet clay on the upper end surface of the turntable 7 and starts the motor 13. The motor 13 drives the second transmission gear 10 to rotate through the drive shaft 21 and the sleeve rod 25. Then, through the meshing assembly of the first transmission gear 9 and the second transmission gear 10, the turntable 7 can be rotated on the upper end surface of the lifting platform 5. At this time, the staff can shape the wet clay with their hands.

[0039] When the turntable device of this embodiment is just started, the bottom of the dome latch 29 is engaged with a circular arc positioning groove 30 in the middle, that is, the paddle 14 and the snap ring 24 are in the middle position. When the staff needs to raise or lower the turntable 7 during the clay molding process, the staff can place their knees or calves inside the snap ring 24 and deflect the position of the snap ring 24 and the paddle 14 through their knees or calves. The paddle 14 can then deflect the assembly plate 16 through the rotating ring 12, so that the two third transmission gears 20 at the forked ends of the assembly plate 16 can alternately mesh with the limit gear 3.

[0040] Since the two third transmission gears 20 at the forked ends of the assembly plate 16 move synchronously in opposite directions, when the two third transmission gears 20 alternately engage and transmit with the limit gear 3, the rotation direction of the limit gear 3 can be adjusted, and the limit gear 3 rotates with the threaded rod 2. In addition, the internal threaded sleeve 4 and the lifting platform 5 are limited by the optical axis 6, so the lifting platform 5 can adjust the turntable 7 to rise or fall without manual adjustment and without mud and water adhering to the surface of the retaining ring 24.
