Description

Technical Field

[0001] The invention relates to the technical field of ceramic hand-painting, and more specifically, to a lifting and rotating device for ceramic hand-painting coloring. Background Art

[0002] Ceramics is a general term for pottery and porcelain. It is also a kind of arts and crafts in my country. As early as the Neolithic Age, my country already had rough and simple painted pottery and black pottery. The texture and properties of pottery and porcelain are different. Pottery is made of clay with high viscosity and strong plasticity as the main raw material. It is opaque, has fine pores and weak water absorption, and has a turbid sound when hit. Porcelain is characterized by dense and delicate texture, smooth surface and a certain sense of transparency. This is mainly due to the fact that during the high-temperature firing process of about 1300℃, the internal material undergoes a vitrification reaction, which makes it hard and corrosion-resistant porcelain. When preparing ceramics, they need to be placed on a lifting and rotating device for hand-painting. When painting overglaze or underglaze colored porcelain, the height of the painting table has an important influence on the painting effect and process accuracy. Tables of different heights will affect the painter's hand stability, viewing angle, force application method, etc., and thus affect the quality of the final porcelain pattern.

[0003] At present, the ceramic hand-painting process requires a stable and adjustable work surface so that artists or craftsmen can apply colors accurately. However, the existing technology has the following disadvantages: 1. Insufficient stability of the rotating mechanism: Most existing hand-painting tables use simple bearing rotating mechanisms, which are prone to shaking and affect the drawing accuracy; 2. Low lifting control accuracy: Many existing devices use manual adjustment and lifting, which is inconvenient to adjust and difficult to accurately control the height; 3. Single fixing method: Traditional clamping mechanisms often cannot adapt to ceramic workpieces of different sizes and shapes, limiting the scope of application; 4. Insufficient safety: Some devices may be displaced during rotation or lifting, and lack reliable locking or anti-slip mechanisms.

[0004] Therefore, it is urgent to invent a lifting and rotating device for ceramic hand-painting coloring to improve the stability, accuracy and ease of operation of ceramic hand-painting coloring. Summary of the invention

[0005] The technical solution adopted by the present invention to achieve the technical purpose is: a lifting and rotating device for hand-painting ceramics, the structure of which includes a workbench, a support backboard, an operating mechanism, a pressing mechanism and a control panel.

The pressing mechanism is fixed on the top of the support backboard, and the pressing mechanism is located directly above the operating mechanism. The control panel is embedded in the front surface of the upper end of the workbench, and the control panel is electrically connected to the operating mechanism. The operating mechanism is composed of a tray, a lifting slider, a ball screw, a rotating rod and a motor. The middle of the rear end of the tray is fixedly installed with a lifting slider, and the lifting slider is slidably installed inside the front end of the support backboard. The ball screw is in clearance fit through the inside of the lifting slider. The top of the ball screw is welded to the bottom of the rotating rod, and the upper end of the rotating rod rotates synchronously with the output end of the motor. The motor is fixedly installed in the middle of the top of the support backboard; A rotating mechanism is arranged on the tray.

The stepping motor is fixed at the bottom of the tray, and the output end of the stepping motor drives the driving wheel disc to rotate synchronously. The driving wheel disc drives the driven wheel disc to rotate synchronously through the synchronous belt. The driven wheel disc is fixedly installed at the bottom of the carrying turntable. A magnetic encoder is also installed at the bottom of the carrying turntable. The diameter of the driven wheel disc is three times that of the driving wheel disc.

[0006] As a further improvement of the present invention, an air guide groove is further arranged inside the carrying turntable, and the upper end of the air guide groove is connected to the adsorption port at the upper end inside the carrying turntable in a through manner. The upper end of the adsorption port is also connected to a flexible silica gel suction cup in a through manner. A guide block is arranged on the side of the carrying turntable, and the guide block is slidably assisted by a pulley inside the tray. Thirteen adsorption ports are provided, and they are arranged in a cross-shaped structure and distributed inside the upper surface of the carrying turntable.

[0007] As a further improvement of the present invention, an adsorption mechanism is arranged at the bottom of the carrying turntable. The adsorption mechanism is composed of a negative pressure machine, a negative pressure pipe, a connecting mechanism and a support rod. The negative pressure machine is fixed at the bottom of the tray, and the negative pressure machine is connected to the inside of the connecting mechanism in a through manner through the negative pressure pipe. The middle of the connecting mechanism is fixed at the middle end of the bottom of the tray through a support rod, and one end of the support rod is welded to the bottom of the tray.

[0008] As a further improvement of the present invention, the connecting mechanism consists of a connecting pipe, a limit block, a rotating ring and an air intake pipe.

The upper end of the connecting pipe is connected to the air guide groove inside the supporting turntable. Two limit blocks are arranged and are symmetrically installed inside the connecting pipe. The rotating ring can be limited and rotated by the limit blocks on both sides.

[0009] As a further improvement of the present invention, the pressing mechanism is composed of a supporting top rod, an air pressure tube, a spring, an extrusion rod and a contact plate. The rear end of the supporting top rod is fixedly mounted on the front surface of the upper end of the supporting back plate, and the bottom of the supporting top rod is welded to the top of the air pressure tube. A spring is arranged inside the air pressure tube, and is welded to the upper end of the extrusion rod through the spring, so that the extrusion rod is elastically extruded inside the air pressure tube.

[0010] The beneficial effects of the present invention are: When the negative pressure machine is started and the negative pressure tube and the connecting mechanism are connected, negative pressure is generated in the air guide groove inside the carrying turntable. At this time, the suction port firmly adsorbs and fixes the bottom of the ceramic, fixes the ceramic by adsorbing it on the bottom, and cooperates with the air pressure tube, spring and extrusion rod on the top to elastically adjust the lifting and lowering of the resistance plate. With the eight telescopic hoses independently elastically connected, the eight extrusion plates can be automatically adjusted, which is convenient for elastic resistance limiting of the uneven ceramic top, improving the stability of the ceramic during rotation, achieving unobstructed fixation of the ceramic surface, improving the smoothness of hand-painted ceramic coloring, and thus improving the effect of hand-painted ceramic coloring.

[0022] As a further improvement of the present invention, the pressing mechanism 4 is composed of a supporting ejector rod 41, a pneumatic tube 42, a spring 43, a pressing rod 44 and a contact plate 45. The rear end of the supporting ejector rod 41 is fixedly installed on the front surface of the upper end of the supporting back plate 2, and the bottom of the supporting ejector rod 41 is welded to the top of the pneumatic tube 42.

In the present invention, the ceramic is placed on the upper surface of the bearing turntable 3115 in the middle of the supporting plate 31. At this time, when the negative pressure machine 3121 is started and penetrates through the negative pressure tube 3122 and the connecting mechanism 3123, a negative pressure is generated in the air guide groove 1151 inside the bearing turntable 3115. At this time, the adsorption port 1152 firmly adsorbs and fixes the bottom of the ceramic.

When hand-painting and coloring, by operating the control panel 5 to start the motor 35, the ball screw 33 rotates to drive the supporting plate 31 to lift and adjust the ceramic, and the stepping motor 3111 is started to drive the driving wheel disc 3112 to rotate, so that the rotation speed of the driven wheel disc 3114 is slowed down, realizing the effect that the bearing turntable 3115 carries the ceramic to rotate slowly.

[0023] In a preferred technical solution, the control panel 5 is a touch screen control panel, which provides real-time data display, such as rotation angle, lifting height, negative pressure adsorption intensity, etc., and has an intelligent preset mode, such as: "overglaze color mode" (low negative pressure, stable rotation) and "underglaze color mode" (gentle negative pressure, slow rotation) and multi-mode rotation setting, allowing users to select "continuous rotation", "intermittent rotation" or "specific angle pause" mode to adapt to different painting methods.

[0024] In a preferred technical solution, the diameter of the driven wheel disc 3114 is three times that of the driving wheel disc 3112. By driving the driving wheel disc 3112 to rotate through the stepping motor 3111, the rotation speed of the driven wheel disc 3114 is slowed down, realizing the effect that the bearing turntable 3115 carries the ceramic to rotate slowly. A preferred technical solution, the adsorption ports 1152 are provided with thirteen and in a cross-shaped structure, distributed inside the upper surface of the carrying turntable 3115, and the contact area with the ceramic bottom placed on the upper surface of the carrying turntable 3115 is expanded through the thirteen adsorption ports 1152, and a flexible silicone suction cup 1155 is used to improve the ability to adapt to different ceramic shapes, and the surface of the carrying turntable 3115 adopts a non-slip silicone layer to improve the uniformity of adsorption and reduce the risk of damage caused by direct contact, and a flexible sealant is provided on the bottom surface of the flexible silicone suction cup 1155 to improve the adsorption stability, and a magnetic sheet is provided on the bottom surface of the flexible silicone suction cup 1155 coated with a flexible sealant, and the flexible silicone suction cup 1155 can be adjusted by magnetism to adapt to different glazes, and manual switching of adsorption pads of different materials is allowed; A preferred technical solution, the limit blocks 1232 are provided with two, and are installed in the connecting tube 1231 in a symmetrical manner. The limit blocks 1232 on both sides can limit the rotation of the rotating ring 1233, so that the rotating ring 1233 and the air inlet pipe 1234 can rotate on the connecting tube 1231, ensuring that the air inlet pipe 1234 is fixed to the middle end of the bottom of the bearing turntable 3115 and is sealed and connected to the inside of the air guide groove 1151, so that the adsorption port 1152 can adsorb the bottom of the ceramic, and fix the ceramic on the upper surface of the bearing turntable 3115. The unobstructed fixation improves the smoothness of hand-painting of the ceramic, thereby improving the effect of hand-painting of the ceramic; A preferred technical solution is that there are eight telescopic hoses 451, eight extrusion plates 452 and eight sponge pads 453, and a rotating ball is also provided at the bottom of the extrusion rod 44 to rotate the angle of the extrusion plate 452, and the eight independent extrusion plates 452 form a long plate state and are located at the bottom of the resistance plate 45.
