Description

Technical Field

[0001] This utility model relates to the technical field of grinding devices for ceramic product processing, and more specifically, it relates to a grinding device for ceramic product processing. Background Technology

[0002] Ceramics, a general term for pottery and porcelain, is an important category of arts and crafts in my country. As early as the Neolithic Age, thousands of years ago, our ancestors created rustic and simple painted and black pottery. Pottery and porcelain differ significantly in texture and properties. Pottery is mainly made from highly viscous and malleable clay, characterized by its opaque texture, fine pores, slight water absorption, and a relatively dull sound when struck.

[0003] Utility model patent application publication number 202123199382.X discloses a fully automatic fine grinding equipment for ceramic products, including a base and a placement seat. A support frame is fixedly installed on the upper part of the base, and a spiral hole is opened on the upper part of the support frame. A spiral rod is movably installed inside the spiral hole, and a connecting rod is fixedly installed on the lower part of the spiral rod. A limiting plate is fixedly installed on the side of the connecting rod, and an installation opening is opened on the lower side of the limiting plate. A rotating rod is movably installed inside the installation opening, and an extension rod is movably connected to the limiting plate through the rotating rod. In this fully automatic fine grinding equipment for ceramic products, the rotation and rise of the spiral rod can drive the connecting rod to rotate and rise. At the same time, the connecting rod can drive the extension rod and the grinding ball to rotate. The side of the grinding ball is in contact with the inside of the ceramic product, thereby grinding the inside. At the same time, the centrifugal force during rotation keeps the grinding ball in contact with the inside. The rise of the connecting rod can drive the grinding ball to rise stably for grinding, thus achieving the purpose of facilitating the grinding of the inside.

[0004] Although the above-mentioned device can grind the inside of the workpiece, it still has the following problems: 1. This device can only perform a single grinding operation on the inner or outer wall of the workpiece. After completing one side, it is necessary to re-clamp or change stations to grind the other side. This batch operation mode forces the workpiece to undergo two independent processing steps, significantly extending the total processing time of a single product and resulting in a decrease in overall grinding efficiency.

[0005] 2. Although it can be adjusted to accommodate workpieces of different diameters, its adjustable range is limited, and it has poor compatibility with excessively large or small sizes. More importantly, the device cannot precisely control the contact pressure between the grinding ball and the workpiece surface, severely affecting the grinding effect.

[0006] 3. When grinding the inner wall of ceramic workpieces, the device lacks a built-in real-time dust extraction or cleaning mechanism. The generated micron-sized ceramic dust continuously accumulates in the internal cavities of the workpiece. This not only interferes with the subsequent grinding process but also necessitates manual intervention for specialized cleaning later, adding extra time and labor costs.

[0007] Therefore, there is an urgent need for a grinding device for processing ceramic products. Utility Model Content

The grinding box 1 is fixedly connected to an electric push rod 25, and the telescopic end of the electric push rod 25 is fixedly connected to the air guide pipe 23. The grinding box 1 is fixedly connected to and connected to an exhaust pipe 26.

[0027] Please see Figure 2 and Figure 7 The central structure includes a support base 27, which is fixedly connected to the grinding box 1. The support base 27 is provided with circumferentially spaced through slots. A pressing rod 28 is slidably connected in the through slots of the support base 27. A rotating ring 29 is rotatably connected to the support base 27. The rotating ring 29 is provided with circumferentially spaced inclined through slots.

A second motor 31 is fixedly connected to the grinding box 1. A third gear 32 is fixedly connected to the output shaft of the second motor 31. The third gear 32 is fixedly connected to the gear ring 30.

[0028] Working principle: Before use, connect the exhaust pipe 26 to the dust collection box and the air guide pipe 23 to the air pump. Place the workpiece on the support base 27, then close the sealing door 2 and press the start button of the controller 3. The controller 3 first starts the motor 2 31. The output shaft of the motor 2 31 drives the gear 3 32 to rotate. The gear 3 32 drives the gear ring 30 to rotate. The rotating ring 29 rotates along the support base 27. Under the action of the inclined through groove, the three extrusion rods 28 move closer to each other and slide along the through groove of the support base 27, thereby extruding the workpiece and placing the workpiece in the center position of the support base 27. Then, control the output shaft of the motor 2 31 to rotate in the opposite direction, thereby separating the three extrusion rods 28 from each other. Then, start the electric push rod 25. The telescopic end of the electric push rod 25 drives the air guide pipe 23 to move downward. The extrusion plate 24 extrudes and fixes the workpiece. Then, turn off the electric push rod 25.

[0029] Controller 3 starts electric push rod 6, which drives sliding frame 5 to slide downward along guide roller. Sliding frame 5 drives rotating disk 8 to move downward until grinding part 20 enters the interior of workpiece. Then, motor 15 is started, and the output shaft of motor 15 drives gear 16 to rotate. Gear 16 drives gear 14 to rotate. Gear 14 drives rotating disk 8 to rotate circumferentially through rotating sleeve 7. During the rotation of rotating disk 8, the two counterweights 12 move away from each other under the action of centrifugal force. Elastic element 13 is stretched. Counterweights 12 drive adjacent sliding parts 9 to move synchronously. The two sliding parts 9 move closer to each other, and then the two grinding parts 11 move closer to the workpiece until the grinding parts 11 contact the outer wall of the workpiece.

[0030] Simultaneously, under the action of centrifugal force, the two sliding blocks 18 move away from each other, and at this time, the two grinding parts 20 move away from each other, the elastic element 22 is stretched, and the two grinding parts 20 contact the inner wall of the workpiece. The rotating disk 8 drives the two grinding parts 11 to grind the outer wall of the workpiece, and the two grinding parts 20 grind the inner wall of the workpiece. During the grinding process, the extension end of the electric push rod 6 is controlled to drive the sliding frame 5 to move upward, thereby grinding the inner and outer walls of the workpiece.

[0031] During grinding, the air pump is started to inject high-pressure air into the air guide pipe 23. The high-pressure air is sprayed out from the air guide pipe 23 to clean the dust inside the workpiece, and then discharged from the exhaust pipe 26. After the workpiece is ground, the telescopic end of the electric push rod 6 is reset, and then the motor 15 is turned off. At this time, under the elastic force of the elastic element 13, the counterweight 12 and the sliding element 9 are reset. Under the elastic force of the elastic element 22, the sliding block 18 is reset. Grinding parts 11 and 20 are separated from the workpiece.

[0032] Then start the electric push rod 25. The electric push rod 25 drives the exhaust pipe 26 to move upward. As the exhaust pipe 26 moves upward, the extrusion plate 24 loses its separation from the workpiece, releasing the fixation of the workpiece. Then open the closed door 2 and take out the workpiece.
