[0002] The quality of the brown glaze used in electrical porcelain insulators must be considered not only in terms of appearance but also in terms of its internal quality. This all boils down to whether the brown glaze can match the body of the porcelain. A good brown glaze can bond well with the body, and after porcelain is made, an excellent intermediate layer can be formed between the glaze and the body, which can significantly improve the mechanical strength, electrical strength, thermal stability, and so on of the porcelain.

[0003] When glazing the insulator blank, the glaze has poor dispersion, which affects the effect after glazing. Moreover, since the blank surface is not treated before glazing, the glaze adhesion is poor and the glaze layer is uneven. Summary of the Invention

A drying control module controls the drying process of the billet according to the ultra-wet signal, so that the difference between the wet weight data M1 and the dry weight data M0 of the billet meets the predetermined requirements of the wet weight billet.

[0010] In one embodiment of the present invention, the glazing measurement module includes: The glazing signal acquisition module acquires a glazing completion signal when the time for the body to be immersed in the glaze slurry reaches a predetermined time.

[0019] Please see Figure 1 This invention provides a glazing system for universal brown glaze on high- and low-grade electrical porcelain insulator blanks, characterized in that it comprises: The glaze slurry processing module controls the input of pre-processed raw materials, which are accurately proportioned according to the designed ingredient list, into the ball mill jar in a predetermined ratio of material, balls, and water. It also controls the addition of a predetermined amount of sodium carboxymethyl cellulose (CMC) ball milling oil, and after pretreatment, the materials are aged for later use to obtain glaze slurry. The wetting control module collects the dry weight data M0 of the insulator blank in the dry state and the first image data of the blank in the vertical state, and controls the wetting treatment of the blank in the dry weight state. The wet weight determination module collects wet weight data M1 of the billet in a wet state, and determines whether the difference between the wet weight data M1 and the dry weight data M0 meets the predetermined requirements of the wet weight billet. If not, it controls the rotation and drying of the billet in the wet state to treat the moisture until the predetermined requirements of the wet weight billet are met. A glazing measurement module, wherein the module controls the immersion of the wet-weight blank in the glaze slurry for a predetermined time, then removes it and controls the blank to be in an upright position, and measures the weight data M3 of the glazed blank; and The glazing control module determines whether the difference between the weight data M3 and the dry weight data M0 meets the predetermined requirements for glazing the body. If not, it collects second image data corresponding to the first image data when the glazed body is in a vertical state, and determines the offset of the body in the second image data relative to the body in the first image data. It then controls the glazing at the corresponding position until the difference between the weight data M3 and the dry weight data M0 meets the predetermined requirements for glazing the body.

[0020] In one embodiment of the present invention, during the glazing of insulators using brown glaze, a glaze slurry processing module is used to fully control the ball milling and mixing of materials, balls, water, and sodium carboxymethyl cellulose, and sodium carboxymethyl cellulose is used to achieve decoction and dispersion. A wetting control module is used to collect the dry weight data M0 of the insulator in a dry state and to acquire the first image data of the vertical and dry insulator blank. This allows for secondary glazing treatment of the glazed insulator using a glazing spray control module when acquiring the second image data after glazing, thereby improving the uniformity of the glaze treatment. After obtaining the dry weight data M0 of the blank, a wet weight judgment module is used to determine the wet weight data M1 of the blank in a wet state. If there is too much water, the moisture content is controlled by judging the weight, thus confirming that water is used to treat the blank to remove dust from its surface, while also adding a certain amount of water to the blank to prevent the blank from absorbing too much water from the glaze slurry, which would affect glazing, and also to avoid excessive moisture on the surface of the blank. The weight of the glaze after dipping is then measured by the glazing measurement module to determine whether the weight of the glaze meets the standard, thereby ensuring the uniformity of the glaze distribution.

[0021] It is worth noting that, during the raw material formulation process, the optimal overall effect of the brown glaze is achieved by selecting the following proportions: potassium feldspar (18-26 parts), sodium feldspar (6-14 parts), Dongsheng clay (2-8 parts), Shaanxi kaolin (10-18 parts), calcined talc (4-12 parts), limestone (0-4 parts), iron oxide red (25-33 parts), chromium oxide green (0.8-1.6 parts), chromium oxide green (0.4-1.2 parts), and Chongqing manganese oxide (4-12 parts).

[0022] During the preparation of the green body test strips, take the green clay at normal working moisture level and extrude it into test strips with a diameter of about 20 mm and a length of about 130 mm on a ZLN-65L vertical vacuum ply mill. Place the extruded test strips on a platform covered with newspaper to air dry until they turn white, then put them in an oven and dry them at a temperature of 50-60℃ until the moisture content is below 1.5% (about 4-5 hours). Let them cool to room temperature for later use.

[0023] The predetermined ratio of material, balls, and water in the glaze slurry processing module is 1:2.5:0.8, and the CMC content is 0.3%.

[0024] The pretreatment includes: ball milling the glaze for 20 hours, controlling the ball milling fineness to a 360-mesh sieve residue of 0.06-0.3%, passing it through a 200-mesh sieve, then pouring it into a plastic bucket, removing iron four times with a magnetic rod, and aging it for 4-5 hours. This ensures the uniformity of the glaze mixing and the overall performance of the glaze after application.

[0025] The wetting control module includes: A dry weight acquisition module, which controls the blank to be wetted to acquire dry weight data M0 in a dry weight state; An image acquisition module, wherein the image acquisition module controls the acquisition of image data of the billet in a free and vertical state under dry weight, so as to obtain the first image data; and A wetting treatment module controls the wetting treatment of the surface of the blank.

[0026] In one embodiment of the present invention, a dry weight acquisition module is used to acquire the dry weight data M0 of the green body under dry weight conditions, and an image acquisition module is used to acquire first image data for comparison with second image data. A wetting treatment module is used to control the wetting treatment of the green body to remove dust from its surface. At the same time, a certain amount of water is added to the green body to prevent it from absorbing too much water from the glaze slurry, which would affect the glazing.

[0027] The wet weight determination module includes: A wet weight acquisition module, wherein the wet weight acquisition module controls the acquisition of wet weight data M1 of the billet after the surface of the billet is wetted; An ultra-humidity signal acquisition module acquires an ultra-humidity signal when the difference between the wet weight data M1 and the dry weight data M0 of the billet exceeds the predetermined requirement for the wet weight of the billet. A drying control module controls the drying process of the billet according to the ultra-wet signal, so that the difference between the wet weight data M1 and the dry weight data M0 of the billet meets the predetermined requirements of the wet weight billet.

[0028] In this embodiment of the invention, a wet weight acquisition module is used to collect the wet weight data M1 of the wetted body. An over-humidity signal acquisition module is used to determine whether the moisture content of the body exceeds the standard. If it does, the drying control module controls the moisture content on the surface of the body to ensure that the glazing standard is met.

[0029] The glazing measurement module includes: The glazing signal acquisition module acquires a glazing completion signal when the time for the body to be immersed in the glaze slurry reaches a predetermined time. The removal control module controls the removal of the blank after the glazing completion signal has been collected, and controls it to be arranged in a free vertical state. The weight measurement module collects the weight data M3 of the glazed body.

[0030] In one embodiment of the present invention, the glazing signal acquisition module accurately determines the glazing time, and the removal control module ensures that the blank is arranged in a free vertical state when it is removed. This allows the weight measurement module to acquire the weight data M3 of the blank after glazing.

[0031] The glazing control module includes: A glaze weight signal acquisition module, wherein the difference between the weight data M3 and the dry weight data M0 does not meet the predetermined requirements for glazing the body; and A glaze treatment module, which controls the further processing of the glazed body surface according to the glaze weight signal.

[0032] In one embodiment of the present invention, a glaze weight signal acquisition module is used to determine whether the glaze weight has reached the predetermined requirement. If it has not reached the requirement, a control signal is sent to the glaze processing module to control the secondary glaze spraying process on the glaze surface.

[0033] The glaze treatment module includes: A glazed blank image acquisition module, which acquires second image data of the glazed blank in a free vertical state; An image comparison module acquires the offset of the blank in the second image data relative to the blank in the first image data; and A spraying control module controls the secondary spraying of glaze onto the surface of the blank on the corresponding offset side until the difference between the weight data M3 and the dry weight data M0 meets the predetermined requirements for glazing the blank.

[0034] In one embodiment of the present invention, when processing the glaze surface, a second image data of the glazed body in a free vertical state is acquired by a glaze blank image acquisition module, and then compared with the first image data by an image comparison module to determine the offset. Subsequently, a second glazing process is controlled by a spraying control module to ensure the uniformity of the glaze surface.

[0035] This invention also provides a method for applying a universal brown glaze to both high- and low-grade electrical porcelain insulator blanks, comprising the following steps: S1: Control the input of pre-processed raw materials, which are accurately proportioned according to the designed batching table, into the ball mill jar in a predetermined ratio of material, balls, and water. Control the addition of a predetermined amount of sodium carboxymethyl cellulose (CMC) ball milling oil, and pre-treat and age it for later use to obtain glaze slurry. S2: Collect the dry weight data M0 of the insulator blank in the dry state and the first image data of the blank in the vertical state, and control the wet treatment of the blank in the dry weight state. S3: Collect the wet weight data M1 of the billet in the wet state, and determine whether the difference between the wet weight data M1 and the dry weight data M0 meets the predetermined requirements of the wet weight billet. If not, control the rotation drying of the billet in the wet state to treat the moisture until the predetermined requirements of the wet weight billet are met. S4: Control the green body in the wet weight state to be immersed in the glaze slurry for a predetermined time and then take it out, and control the green body to be in a vertical position, and measure the weight data M3 of the green body after glazing; S5: Determine whether the difference between the weight data M3 and the dry weight data M0 meets the predetermined requirements for glazing the body. If not, collect the second image data corresponding to the first image data when the glazed body is in a vertical state, and determine the offset of the body in the second image data relative to the body in the first image data. Control the glazing at the corresponding position until the difference between the weight data M3 and the dry weight data M0 meets the predetermined requirements for glazing the body.

[0036] In summary, the glaze slurry obtained by ball milling and mixing materials, balls, water, and sodium carboxymethyl cellulose in a reasonable ratio can effectively improve the uniformity of the glaze slurry, reduce coagulation, and improve dispersibility. By rationally controlling the moisture content of the green body, dust on its surface is removed, and a certain amount of moisture is added to the green body to prevent excessive absorption of water from the glaze slurry, which would affect glazing, while also avoiding excessive moisture on the green body surface that would negatively impact the glazing effect. By monitoring the weight of the green body after glazing and acquiring and comparing images of the green body in a vertical and free state before and after glazing, and by promptly supplementing any missing glaze layers, the uniformity and effectiveness of the glazing are ensured. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and has high industrial application value.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention.
