[0020] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail in combination with the drawings and examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 , the embodiment provides a ceramic casting machine with adjustable blade, which comprises mounting plate 1, fixing block 2, connecting plate 3, blade 4, scale 5 and positioning mechanism 6, mounting plate 1 is used to bear film 7 and other components, fixing block 2 is used to fix connecting plate 3, connecting plate 3 is used to connect blade 4, blade 4 is used to scrape ceramic mud on film 7, so that the thickness of ceramic mud is consistent, scale 5 is used to identify the moving distance of connecting plate 3, and positioning mechanism 6 is used to position fixing connecting plate 3.

[0022] The surface of mounting plate 1 is provided with film 7 wound in a fixed direction, and film 7 is used to bear ceramic mud. Two fixing blocks 2 are respectively arranged on the two sides perpendicular to the winding direction of film 7 and are fixedly connected with mounting plate 1, the fixing block 2 and the mounting plate 1 can be connected in a welding, riveting, threaded connection or the like, and the surface of the fixing block 2 forms an inclined mounting surface 2a, which is used to connect the connecting plate 3. The mounting surfaces 2a of the two fixing blocks 2 are in the same plane, which can facilitate the assembly of the connecting plate 3 and the fixing block 2, and if the mounting surfaces 2a of the two fixing blocks 2 are not in the same plane, the two mounting surfaces 2a must be parallel.

[0023] Connecting plate 3 is slidably connected with the mounting surface 2a at both ends, specifically, the ceramic casting machine with adjustable blade further comprises at least two linear slide rails 8, the fixed ends of the at least two linear slide rails 8 are fixedly connected with the mounting surfaces 2a of the two fixing blocks one by one, and the sliding ends of the linear slide rails 8 are fixedly connected with the connecting plate 3 at both ends, so that the connecting plate 3 and the fixing block are connected by the linear slide rails 8, the assembly is simpler, and the assembly precision is high.

[0024] The scraper 4 is detachably connected with the connecting plate 3. In the embodiment, the scraper 4 is connected with the connecting plate 3 by bolts. In order to finely adjust the scraper 4 to make the scraping surface of the scraper 4 parallel to the mounting plate 1, the connecting plate 3 and the scraper 4 are provided with connecting holes which are slightly larger than the connecting bolts in size. In order to increase the adjustment degree, the waist-shaped holes 5a can be further used to connect the two.

[0025] The scale 5 is connected to the mounting surface 2a and corresponds to the connecting plate 3, and is used to indicate the distance of the connecting plate 3 sliding along the mounting surface 2a.

Preferably, the ceramic casting machine with an adjustable scraper further comprises a pointer 10, which is fixedly connected to the side surface of the connecting plate 3 and corresponds to the scale of the scale 5, and is used to indicate the position of the connecting plate 3.

[0027] The zero adjustment process of replacing the scraper 4 will be briefly described below. After replacing the new scraper 4, move the scraper 4 to make the scraping surface of the scraper 4 fit the surface of the mounting plate 1, and then fix the scraper 4 and the connecting plate 3. At this time, the scraper 4 is parallel to the mounting plate 1.

At this time, the position of the scale 5 is adjusted to make the zero point of the scale 5 correspond to the position of the pointer 10. When the thickness of the ceramic mud on the film 7 needs to be adjusted in the future, only the position of the connecting plate 3 needs to be moved according to the scale of the scale 5 and fixed.
