Description

Technical Field

[0001] The invention relates to the technical field of ceramic product trimming, in particular to an automatic precision trimming device for ceramic products. Background Art

[0002] In the production process of daily-use ceramic products such as plates and dishes, after the clay is initially pressed and processed into a rough blank with a product shape, the edges of the ceramic products need to be ground to make them smooth and round. This process is called "trimming". The traditional trimming operation method is for workers to hold a scraper to operate, but this operation method is not only labor-intensive, but also difficult to ensure the quality of trimming because it is difficult for everyone to use the same operating method and force.

[0003] In recent years, people have designed automatic trimming devices. The existing automatic trimming devices include a rotating support for placing ceramic products, each rotating support is equipped with a rotating drive mechanism for driving its rotation; a trimming scraper is also provided, the trimming scraper is installed on a scraper bracket, and a scraper drive mechanism is also provided for driving the scraper bracket to move back and forth between a working position and a non-working position. When working, the rough ceramic product is placed on the rotating support that is constantly rotating, and the rough ceramic product follows the rotating support to rotate continuously, and then the scraper bracket is driven to reach the working position, so that the blade of the trimming scraper is close to the edge of the rough ceramic product, thereby implementing automatic trimming, which can save labor.

When the present invention is working, it can automatically complete the trimming operation of batches of ceramic products one by one in an assembly line manner, and the device can automatically complete the three-dimensional scanning detection of the ceramic product trimming pliers, the internal and external trimming of the ceramic products, the flipping and mud discharge of the ceramic products after trimming, the negative pressure suction of the ceramic products after mud discharge, and the automatic unloading of the ceramic products after processing.

[0017] 2. In the present invention, before the ceramic product is trimmed, the rotary sweep frame moves to the coaxial position of the ceramic product and moves to the inner cavity of the ceramic product. Then, the rotary sweep frame rotates at a set speed. After the rotary sweep frame rotates, two three-dimensional scanners perform three-dimensional scanning and imaging of the inner and outer walls of the ceramic product and three-dimensional modeling. Through the three-dimensional scanning imaging and modeling of the inner and outer walls of the ceramic product, the undulation of the inner and outer walls of the ceramic product is then determined. When the undulation of the inner and outer walls of the ceramic product exceeds the trimmable threshold, the single-chip microcomputer determines that the ceramic product to be trimmed is waste. When the waste ceramic product moves to the loading area, the waste is transferred to the waste storage box under the action of two clamps;

[0018] 3. In the present invention, after the loading is completed, the inner scraper and the inner scraper shaft move to the adapting connection position with the inner cavity of the ceramic product. After the inner scraper and the inner scraper shaft move, the inner scraper shaft rotates at a set speed, and the ceramic product remains stationary under the action of the two clamps. After the inner scraper rotates, the inner cavity of the ceramic product is trimmed regularly. After the trimming set time, the inner scraper and the inner scraper shaft are moved out from the inner side of the ceramic product. Subsequently, under the driving action of the flipping motor, the ceramic product is flipped over. After the ceramic product is flipped over, the excess mud scraped out of the inner cavity of the ceramic product is discharged. After the ceramic product is flipped over, it automatically resets to the initial state. After the ceramic product is reset, the inner scraper and the inner scraper shaft move to The inner clamping bag is fully inflated at the adapting connection position with the inner cavity of the ceramic product, so as to realize the internal clamping of the ceramic product. After the internal clamping of the ceramic product is completed, the two clamps withdraw the clamping effect on the ceramic product, and then the external trimming operation of the ceramic product is carried out. During the external trimming, under the driving action of the inner clamping bag, the ceramic product moves to the adapting connection position with the outer scraper, and then the outer scraper shaft and the inner scraper shaft rotate differentially, thereby realizing the external trimming of the ceramic product. After the external trimming is completed, the trimmed ceramic product moves to the coaxial setting position with the negative pressure suction shaft, and then the negative pressure vacuum cleaner works, and negative pressure is generated in the chip suction tube, thereby realizing the negative pressure suction removal of residual waste mud on the inner and outer surfaces of the ceramic product.

[0043] When the inner wall of the ceramic product 3 is trimmed, the inner scraper 6 and the inner scraper shaft 5 move to the matching connection position with the inner cavity of the ceramic product 3 again, and the inner clamping bag 24 is fully inflated to achieve the inner clamping of the ceramic product 3. The inner cavity of the inner clamping bag 24 is originally filled with gas. Through the setting of the second air pressure sensor 25, the clamping strength of the ceramic product 3 can be accurately determined by digital monitoring means. After the ceramic product 3 is clamped by the inner clamping bag 24, the outer wall of the ceramic product 3 can be trimmed.

Then, the sweeping frame 35 rotates at a set speed. After the sweeping frame 35 rotates, the two three-dimensional scanners 36 perform three-dimensional scanning and imaging of the inner and outer walls of the ceramic product 3 and three-dimensional modeling. Through the three-dimensional scanning imaging and modeling of the inner and outer walls of the ceramic product 3, the undulation of the inner and outer walls of the ceramic product 3 is then determined. When the undulation of the inner and outer walls of the ceramic product 3 exceeds the trimmable threshold, the single-chip microcomputer 13 determines that the ceramic product 3 to be trimmed is waste.

After the inner scraper 6 and the inner scraper shaft 5 move, the inner scraper shaft 5 rotates at a set speed, and the ceramic product 3 remains stationary under the action of the two clamps 20. After the inner scraper 6 rotates, the inner cavity of the ceramic product 3 is trimmed regularly. After the trimming set time, the inner scraper 6 and the inner scraper shaft 5 are moved out from the inside of the ceramic product 3. Subsequently, under the driving action of the flipping motor 18, the ceramic product 3 is flipped 180°. After the ceramic product 3 is flipped, the excess mud scraped out of the inner cavity of the ceramic product 3 is discharged. After the ceramic product 3 is flipped, it is automatically reset to the initial state. After the ceramic product 3 is reset, the inner scraper 6 and the inner scraper shaft 5 move again to the matching position with the ceramic product 3. At the adapting connection position of the inner cavity of the ceramic product 3, the inner clamping bag 24 is fully inflated, thereby realizing the internal clamping of the ceramic product 3. After the internal clamping of the ceramic product 3 is completed, the two clamps 20 remove the clamping effect on the ceramic product 3, and then the external trimming operation of the ceramic product 3 is carried out. During the external trimming, under the driving action of the inner clamping bag 24, the ceramic product 3 moves to the adapting connection position with the outer scraper 8, and then the outer scraper shaft 7 and the inner scraper shaft 5 rotate at a differential speed, thereby realizing the external trimming of the ceramic product 3. After the external trimming is completed, the ceramic product 3 after trimming moves to the coaxial setting position with the negative pressure suction shaft 26, and then the negative pressure vacuum cleaner 27 works, and negative pressure is generated in the chip suction tube 28, thereby realizing the negative pressure suction and removal of residual waste mud on the inner and outer surfaces of the ceramic product 3.
