[0002] In today's architectural ceramics and decorative materials industry, ceramic tiles are important decorative elements, and their surface quality and processing accuracy directly affect the final decorative effect and service life. As one of the core links in ceramic tile production, the glazing process plays a decisive role in giving ceramic tiles rich colors, gloss and special textures. However, in the traditional glazing process, although advanced glazing equipment has been widely used to improve the uniformity and beauty of the glaze surface, there are still certain technical bottlenecks in the post-glazing treatment stage, especially for the treatment of excess glaze on the side of the ceramic tile.

[0003] At present, most factories use simple manual or semi-automatic tools to scrape off excess glaze on the sides of tiles. This process is not only time-consuming and labor-intensive, but also difficult to ensure uniformity and accuracy of scraping. Manual operation relies on the skills and experience of workers, which can easily lead to problems such as incomplete scraping, obvious scratches, and even damage to the edges of tiles, which seriously affects the appearance quality and yield of the product. In addition, manual processing is inefficient and cannot meet the needs of large-scale production, limiting the increase in production capacity. Summary of the invention

DETAILED DESCRIPTION

[0022] like Figure 1 A device for scraping glaze on the side of a tile after glazing is sprayed comprises a roller conveyor 1, on which a tile centering mechanism 2 and a glaze scraping mechanism 3 are provided;

[0023] The centering mechanism 2 comprises two L-shaped rods 4 respectively passing through the vertical plates on both sides of the roller conveyor 1, and a centering wheel 5 is provided on the end of the L-shaped rod 4 located in the roller conveyor 1;

[0024] The glaze scraping mechanism 3 includes a U-shaped frame 10 arranged across the roller conveyor 1, and a push cylinder 11 is arranged on the U-shaped frame 10. The push rod 111 of the push cylinder 11 faces downward and is connected to the glaze scraping knife 12 arranged on the inner wall of the vertical plate on both sides of the roller conveyor 1.

[0025] In the preferred embodiment, a base 6 with a groove is provided under the roller conveyor 1, and the lower end of the L-shaped rod 4 is located in the groove body of the base 6. A horizontal rotating rod 7 passing through the lower ends of the two L-shaped rods 4 is provided in the groove body of the base 6. One end of the rotating rod 7 extends outside the base 6 and is connected to the motor 9 for transmission. The rotating rod 7 is provided with two threaded sections 8 with opposite rotation directions. The lower end of the L-shaped rod 4 is located on the threaded section 8 and is threadedly matched with the rotating rod 7.

[0026] In the preferred embodiment, a fixed pin hole 15 is provided at one end of the scraper knife 12, and a fixed pin is inserted into the fixed pin hole 15 to fix the scraper knife 12 on the inner walls of the vertical plates on both sides of the roller conveyor 1. A strip hole 16 is provided in the middle of the scraper knife 12, and a horizontal adjustment cross bar 17 is provided at the lower end of the push rod 111. The two ends of the adjustment cross bar 17 are respectively located in the strip holes 16 in the middle of the two scrapers 12.

[0027] In a preferred embodiment, a triangular notch is provided on the scraping end of the scraper 12, and the triangular notch forms a tile top edge scraper 13 and a tile side scraper 14 on the scraper 12;

[0028] The tile top edge scraper 13 contacts the glaze on the top surface of the tile, and the tile side scraper 14 contacts the side walls of the tile.

[0029] In a preferred solution, a waste glaze hopper 18 is further provided on the bottom of the roller conveyor 1 below the glaze scraping mechanism 3 .

[0030] The present invention discloses a device for scraping the side glaze of a tile after glazing. When performing the glazing scraping operation after glazing the tile:

[0031] The roller conveyor 1 conveys the glazed tile products, and adjusts the lateral position of the tiles passing through the tile centering mechanism 2 through repeated forward and reverse rotation of the motor 9 to ensure that both sides of the tiles are aligned with the glaze scraping mechanism 3. Due to the synchronous relative or opposite movement of the two L-shaped rods 4 in the tile centering mechanism 2, the position of the tiles before scraping the glaze can be accurately controlled. After the position control adjustment is completed, the tiles are continued to be conveyed by the roller conveyor 1 to the glaze scraping mechanism 3. Before scraping the glaze, the inclination angle of the glaze scraper 12 is controlled by controlling the telescopic action of the push rod 111 of the push cylinder 11, so as to finally realize the control of the scraping glaze thickness. When the tile passes the position of the glaze scraper 12, the glaze on the edges of the top surface of the tile is scraped off by the glaze scraper 13 on the top edge of the tile, and the residual glaze on the sides of the tile is scraped off by the glaze scraper 14 on the side of the tile. The scraped glaze passes through the gap between the rollers of the conveying roller 101 and falls into the waste glaze bucket 18, thereby realizing the recycling of the waste glaze.

[0032] In the above scheme, a corresponding sensor (such as an infrared sensor, a proximity switch, etc.) can be further arranged at the front end (i.e., the input direction) of the tile centering mechanism 2 to monitor the position of the tile product, so that when the tile passes through the tile centering mechanism 2, the motor 9 can be quickly moved to avoid untimely centering.

[0033] A waste glaze collection box with negative pressure suction function can be added at the bottom of the waste glaze hopper 18. A filter screen is installed in the box to prevent large particles from clogging the pipeline. The collection box has a capacity of 100L. When it reaches 80% full, the sensor triggers an alarm and stops the production line, waiting for cleaning.

[0034] The entire device adopts a PLC control system and an integrated touch screen human-machine interface, so operators can intuitively monitor production status, adjust parameters, and view fault alarm information. The system presets processing programs for multiple tile specifications, which can be switched with one button to simplify the operation process.
