Description

Technical Field

[0001] This utility model belongs to the field of ceramic glaze performance testing technology, specifically relating to a device for preparing test pieces with different glaze thicknesses. Background Technology

[0002] In the research and development and production process of ceramic glazes, glaze thickness is one of the key variables affecting the final color, gloss, texture, and microstructure of the glaze surface. Accurately evaluating the firing performance of the same glaze at different thicknesses is crucial for optimizing formulas, guiding production, and exploring artistic effects.

[0003] Currently, the conventional method for comparative testing of glaze thickness in the industry mostly relies on applying glaze separately to different ceramic slab test pieces. Specific operations typically employ processes such as immersion glazing, spraying glazing, or brushing glazing, with thickness roughly controlled by adjusting the glaze concentration, immersion time, or number of spray passes. This method has significant limitations: First, it is inefficient, as each thickness test point requires independent preparation of a test piece, leading to a significant increase in the consumption of body material, glaze, and energy. Second, consistency is difficult to guarantee; manual operation easily introduces thickness errors between different test pieces, and even between different areas of the same test piece, resulting in inconsistent basic conditions for comparative experiments and reduced data reliability and comparability. Third, it occupies a large amount of kiln space; in limited experimental or production kilns, a large number of test pieces severely crowd out the effective volume.

[0004] Therefore, the field of ceramic glaze performance testing urgently needs an integrated experimental platform that can conveniently and accurately achieve the simultaneous preparation and firing of multiple preset glaze thicknesses on a single substrate. Summary of the Invention

[0005] The purpose of this invention is to provide an apparatus for producing test pieces with different glaze thicknesses, so as to overcome the problems of low efficiency, poor consistency and waste of resources in the existing technology.

[0015] Reference Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides an apparatus for producing test pieces with different glaze thicknesses, comprising an outer frame 1, an inner frame 2, a pressure block structure 3, a screw structure 4, and a pressure plate 5; The outer frame 1 is a rectangular frame structure composed of four sides; each of the four sides of the outer frame 1 has a cutting edge 13 for cutting mud slices 6 along its lower edge; a ring A12 is fixed to the top of the outer frame 1 by multiple connecting rods A11; the multiple connecting rods A11 are arranged in an X-shape, and the ring A12 is located in the middle of the top of the outer frame 1, and the multiple connecting rods A11, the ring A12, and the outer frame 1 are connected by welding, such as... Figure 2 As shown; the inner frame 2 is also a rectangular frame structure, consisting of four sides and a bottom surface; the top of the inner frame 2 is fixed with a ring B22 by multiple connecting rods B21; the multiple connecting rods B21 are distributed in an X shape, the ring B22 is located in the middle of the top of the inner frame 2, and the multiple connecting rods B21, the ring B22 and the inner frame 2 are connected by welding, as shown. Figure 3 As shown. To increase strength, horizontal or diagonal bars can be added to the top of the outer frame 1 and the inner frame 2. For example, horizontal bars can be added to the outer frame 1, with the bars set on two opposite sides, their ends welded to the outer frame 1, and the corresponding middle position welded to the connecting rod; when adding diagonal bars, diagonal bars are set at all four corners, with the ends welded to the outer frame 1, and the corresponding middle position welded to the connecting rod. The inner frame 2 is set inside the outer frame 1 and connected to the outer frame 1 through the screw structure 4; the bottom of the inner frame 2 is provided with a pressure block structure 3; the pressure plate 5 is detachably set on the screw structure 4, which consists of a circular pressure plate 51 and a plug seat 52 fixed to the bottom of the circular pressure plate 51. The plug seat 52 is a hollow columnar structure; the circular pressure plate 51 has a circular hole in the middle that communicates with the plug seat 52. The diameter of the circular hole is smaller than the outer diameter of the screw, so the screw will not pass through the circular hole.

[0016] As a further embodiment of this utility model, the screw structure 4 consists of a screw 41 and two sets of nuts threaded onto the screw 41, wherein the screw 41 is a hollow screw; each set of nuts includes two nuts 42, such as... Figure 4 As shown; the screw 41 passes through ring A12 and ring B22, and is connected to the outer frame 1 and the inner frame 2 through two sets of nuts; the two nuts of the first set are respectively set on the upper and lower sides of ring A12 to lock the position of ring A12; the two nuts of the second set are respectively set on the upper and lower sides of ring B22 to lock the position of ring B22; the positions of ring A12 and ring B22 can be adjusted by adjusting the two sets of nuts, thereby adjusting the distance between the bottom of the outer frame 1 and the bottom of the inner frame 2.

[0017] As a further implementation of this utility model, the pressure block structure 3 includes a rectangular plate 31, a strip-shaped pressure block 32 fixedly disposed below the rectangular plate 31, a connecting rod 33, and a tension spring 34; one end of the tension spring 34 is connected to the rectangular plate 31, and the other end is connected to the nut inside the inner frame 2; the rectangular plate 31 is connected to the bottom of the inner frame 2 through the tension spring 34, and its edge is in contact with the inner wall of the outer frame 1; the connecting rod 33 passes through the circular pressure plate 51, the plug seat 52, the screw 41, and the tension spring 34 in sequence, and is fixedly connected to the rectangular plate 31. Figure 5 This is a schematic diagram of cutting clay slabs using the device of this utility model. After the clay slabs are cut, they are left to dry for a period of time. Then, the connecting rod 33 is pushed down by hand to separate the rectangular plate 31 from the inner frame 2, thereby pushing the clay slab at the bottom of the outer frame 1 to slowly detach from the outer frame 1 and complete the demolding.

[0018] Furthermore, there are four strip-shaped pressure blocks 32 (the number of strip-shaped pressure blocks can be designed according to actual needs), and the length of each is less than the width of the rectangular plate 31; there is a certain interval between the strip-shaped pressure blocks 32, and the thickness of each pressure block is different. For example... Figure 6 The image shown is a top view of the clay sheet after demolding. Four strip-shaped pressing blocks 32 are used to press out four strip-shaped grooves of different depths for subsequent use.

[0019] This invention allows for the simultaneous cutting of clay slabs and pressing grooves of varying depths into them. The demolded clay slabs can be air-dried or, after air-drying, bisque-fired at 800-900°C before use. The adjusted glaze slurry is stirred thoroughly and then poured into the grooves sequentially, ensuring the glaze does not exceed the top of the grooves. As the clay slab absorbs the glaze, it will shrink to some extent; additional glaze slurry can be added as needed. After drying, the glaze slabs are fired at a high temperature.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
