Description

Technical Field

[0001] The present invention relates to the technical field of cultural and creative product design, and particularly relates to an auxiliary device for cultural and creative product design. Background Art

[0002] Cultural and creative products refer to high - value - added products produced by relying on the wisdom, skills and talents of creative people, with the help of modern scientific and technological means to create and enhance cultural resources and cultural supplies, through the development and application of intellectual property rights. For example, among the top 100 cultural and creative products in China, ceramics is a general term for pottery and porcelain, and it is also a kind of arts and crafts in our country. As far back as the Neolithic Age, there were already rough and simple painted pottery and black pottery in our country. Pottery and porcelain have different textures and properties. Pottery is mainly made of clay with relatively high viscosity and strong plasticity, opaque, with fine pores and weak water absorption, and makes a dull sound when struck. When cultural and creative design is combined with ceramics, various ceramic cultural and creative products will be produced.

[0003] Throwing is an essential process in the production of ceramics, and it is also the basis for the design and creation of ceramic cultural and creative products. When throwing ceramics, an auxiliary device is needed to achieve a more efficient creative effect. Hand - throwing forming is an ancient technique. It is a method of manually pulling plastic clay into various shapes on a rotating turntable. Now, electric wheels are used for throwing wheels, while in the past, hand - cranked wheels were used. The hand - cranked wheel is a special blue - stone turntable fixed on a wheel axle. There is a small pit at the upper edge of the stone wheel. Hold a slender wooden stick and insert it into the small pit, and shake it forcefully in the counter - clockwise direction to make the stone wheel rotate quickly. Place a clay mass on the stone wheel. After the stone wheel starts to rotate, use its inertia to throw the clay. When the rotation speed of the stone wheel decreases and is about to stop, continue to rotate the stone wheel to keep it running. Repeat this process until the clay is formed. This is a manifestation of the mature and exquisite operation skills of ceramic creators. However, upon careful observation, it can be found that the surfaces of porcelain made by hand - throwing all have irregular hand - throwing marks, some are in circles, and some are of different depths, which seriously reduces the aesthetics of ceramics and has an adverse impact on the cultural value and market value of ceramic cultural and creative products. Therefore, there is an urgent need to design an auxiliary device for cultural and creative product design to solve the problems in the existing technology. Summary of the Invention

A connecting member is provided at the lower end of the rack 9. A turning tool 15 for turning a ceramic blank is provided on the connecting member.

[0023] Working principle: When the first driving part 6 is working, it can drive the ball screw 4 to rotate forward or reverse. Under the guidance of the "U"-shaped groove 3, the screw nut 5 drives the slide groove 8 to perform linear reciprocating motion through the "L"-shaped connecting rod 7. When the second driving part 10 is working, it can drive the gear 11 to rotate forward or reverse. The gear 11 drives the connecting part and the sharpening knife 15 to perform reciprocating lifting motion through the rack 9, thereby making the sharpening knife 15 perform a compound motion of lifting and horizontal linear motion, so that the motion trajectory of the sharpening knife 15 is consistent with the contour of the ceramic body. During the cutting process, the sharpening knife 15 trims the outer surface of the ceramic body.

[0024] During specific use, the ceramic creator throws the clay into shape and then inverts it at the center of the turntable 2 with the opening facing downward. The driving mechanism drives the turntable 2 to rotate, starts the first driving part 6 and the second driving part 10, and the sharp blade 15 trims the outer surface of the ceramic body according to the outer contour of the ceramic body to remove the hand-thrown marks on the outer surface of the ceramic body.

[0025] In order to achieve the purpose of trimming the inner surface of the ceramic blank, preferably, the connecting part includes a third driving part 12 arranged at the lower end of the rack 9, the output end of the third driving part 12 is provided with a first rotating shaft 13, the end of the first rotating shaft 13 is provided with a vertical rod 14, the blank knife 15 is arranged at the end of the vertical rod 14, and a support frame 19 is provided on the workbench 1, and a suction cup 20 is connected to the support frame 19 for lifting and rotating, and the suction cup 20 is connected to a vacuum generating device 21, the vacuum generating device 21 is a vacuum generator or a vacuum pump, the third driving part 12 is a motor or a rotary cylinder, and the blank trimming knife 15 is fixed to the vertical rod 14 by bolts, which is convenient for replacing the worn blank trimming knife 15 or adjusting the installation angle of the blank trimming knife 15.

A driving bevel gear 26 is provided at the output end of the fifth driving part 25. A driven bevel gear 27 meshing with the driving bevel gear 26 is provided on the second rotating shaft 24.

[0027] Specifically, after the outer surface of the ceramic blank is trimmed, the turntable 2 stops rotating, the trimming knife 15 resets, the telescopic end of the first telescopic device 22 extends, drives the suction cup 20 to descend and contact the ceramic blank. After the vacuum generating device 21 operates to form a negative pressure inside the suction cup 20 to suck the ceramic blank, the telescopic end of the first telescopic device 22 contracts to drive the ceramic blank to rise. The fifth driving part 25 operates to drive the driving bevel gear 26 to rotate. The driving bevel gear 26 drives the second rotating shaft 24 to rotate through the driven bevel gear 27. The second rotating shaft 24 drives the ceramic blank to rotate through the suction cup 20. The third driving part 12 drives the first rotating shaft 13 to rotate by 90 degrees. The first rotating shaft 13 drives the trimming knife 15 to rotate by 90 degrees through the vertical rod 14, making it face upward. According to the inner contour of the ceramic blank, the trimming knife 15 extends into the interior of the ceramic blank to trim the inner surface of the ceramic blank, removing the hand-drawn blank lines on the inner surface of the ceramic blank, which is beneficial to improving the aesthetics of the finished ceramic ware, and is beneficial to enhancing the cultural value and market value of the ceramic cultural and creative products.

The suction cup 20 presses the elastic member 32 to prevent the ceramic blank from being damaged by extrusion, playing a protective role for the ceramic blank. During the specific working process, when the second rotating shaft 24 rotates, the driving groove 29 drives the lower pipe 30 and the suction cup 20 to rotate through the driven block 31. According to the inner contour of the ceramic blank, the profiling tool 15 extends into the ceramic blank to trim the inner surface of the ceramic blank, removing the hand-drawn blank marks on the inner surface of the ceramic blank, which is beneficial to improving the aesthetics of the finished ceramic ware and enhancing the cultural value and market value of the ceramic cultural and creative products.

[0032] To achieve the purpose of automatically cleaning the mud on the turntable 2, preferably, a second telescopic device 33 is horizontally arranged on the support frame 19. The second telescopic device 33 is a cylinder or an electric push rod, and a brush 34 is arranged at the telescopic end of the second telescopic device 33.

[0033] Specifically, after the trimming of the ceramic blank is completed, the turntable 2 is started again. The contact position between the bristles of the brush 34 and the upper surface of the turntable 2 is adjusted by the telescopic movement of the telescopic end of the second telescopic device 33. With the cooperation of the centrifugal force, the bristles of the brush 34 scrape off the excess mud on the upper surface of the turntable 2, automatically cleaning the turntable 2.

[0034] To achieve the purpose of trimming the ceramic blank, preferably, a mud guard 35 is arranged between the "U"-shaped groove 3 and the turntable 2.

[0035] Specifically, the mud guard 35 is used to block the mud and prevent the mud from falling into the interior of the "U"-shaped groove 3, affecting the transmission component, enabling the profiling tool 15 to move horizontally normally, and extending the service life of the device.

[0037] Specifically, when the fourth driving part 18 works, it drives the worm 17 to rotate. The worm 17 drives the turntable 2 to rotate through the worm gear 16. At the same time, the worm and worm gear reduction transmission has high stability, small frictional loss during the transmission process, and smooth operation, which can ensure the stability of the ceramic blank at the top when the turntable 2 rotates.

[0038] Compared with the prior art, in the present invention, through the cooperation of the workbench 1, the turntable 2, the driving mechanism, the "U"-shaped groove 3, the ball screw 4, the screw nut 5, the first driving part 6, the "L"-shaped connecting rod 7, the sliding groove 8, the rack 9, the second driving part 10, the gear 11, the connecting piece and the turning tool 15, when the first driving part 6 works, it can drive the ball screw 4 to rotate forward or backward.
