Suction cup glaze dipping machine

[0015] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] Such as figure 1 The shown suction cup glaze dipping machine includes a base 1, a turning shaft 2 arranged on the base 1, and a revolution drive mechanism that drives the turning shaft 2 to rotate, and three sets of glaze dipping assemblies arranged on the turning shaft 2 . The revolving drive mechanism includes a revolving motor 31 and a reduction box 32 connected to the output shaft of the revolving motor 31; the rotation motor is drivingly connected to the turning shaft 2 through the reduction box 32. Both ends of the turning shaft 2 are positioned on the base 1 through bearings. The turning shaft 2 between the bearings on both sides is a rectangular columnar body. The three sets of glazing assemblies are all positioned on the rectangular column 2a of the turning shaft 2 through bearings.

[0017] The three sets of glaze dipping assemblies are arranged parallel to each other. The glaze dipping assembly includes a vacuum tube 41 axially positioned on the turning shaft 2 through a bearing, a glaze slurry tube 42 arranged outside the vacuum tube 41, and a glaze slurry tube 42 The suction cup 43 at the top and the rotation drive mechanism that drives the vacuum tube 41 to rotate. The upper end of the vacuum tube 41 communicates with the upper end surface of the suction cup 43, the glaze slurry tube 42 and the vacuum tube 41 form a glaze slurry cavity, and the upper end cavity of the glaze slurry cavity communicates with the upper end surface of the suction cup 43. Specifically: the suction cup 43 has a concave ring structure in the middle, the central through hole of the suction cup 43 communicates with the upper end of the vacuum tube 41, and the suction cup 43 is provided with glazed holes that penetrate the upper and lower ends of the suction cup 43. , The glaze slurry cavity communicates with the upper end surface of the suction cup 43 through the glazing hole. Under the concave ring structure in the middle of the sucker 43, the vacuum tube 41 communicates with the through hole of the ring center of the sucker 43, and the vacuum suction force gradually increases from the periphery of the ring to the middle of the ring, which can promote the adhesion of the ceramic surface to be processed with the sucker 43 , Is conducive to the adsorption and positioning of the ceramic to be processed.

[0018] The rotation driving mechanism includes a rotation motor 51 and a gearbox 52 connected to the output shaft of the rotation motor 51; the rotation motor 51 drives the vacuum tube 41 through the gearbox 52. The rotation driving mechanism is drivingly connected with the vacuum tube 41 of the middle glaze dipping assembly, and the vacuum tube 41 on the middle glaze dipping assembly is connected with the vacuum tubes 41 on both sides of the glaze dipping assembly by belt transmission. This structure is equipped with three sets of glaze dipping assemblies and driven by the same rotation drive mechanism. On the one hand, it is beneficial to improve the efficiency of glazing, and the glazing process can be performed on three ceramics at the same time; on the other hand, it can ensure that the same batch of three ceramics is dipped The glaze time, rotation direction and speed are consistent, so that the optimal process parameters can be selected for simultaneous operation.

[0019] The suction cup 43 glaze dipping machine can be used for the automatic operation of fixed procedures for grabbing, transporting objects or operating tools, thereby replacing people's heavy labor to realize the mechanization and automation of production, and can operate in harmful environments to protect personal safety; it has a structure Simple, the ceramics to be processed can be absorbed smoothly by vacuum, and the ceramics to be processed can be dipped in rotation, which can quickly and efficiently glaze and has the advantages of high reliability. During installation, the suction cup 43 dipping machine is fixed next to the ceramic product glazing process production line, and a glaze pool is installed next to the equipment; before use, a proper amount of glaze slurry needs to be injected into the glaze slurry cavity of the glaze slurry pipe 42; The blank is positioned on the suction cup 43, and the vacuum tube 41 is connected to the vacuum generating device. The negative pressure suction generated by the vacuum tube 41 adsorbs the blank on the suction cup 43; then, control the turning shaft 2 and the glaze assembly on it to rotate to a certain angle , Until two-thirds of the green body is immersed in the glaze pool, the autorotation drive mechanism drives the green body to rotate and evenly glue the glaze slurry, and then control the turning shaft 2 and the glaze dipping assembly on it to reverse reset, and the green body continues Rotate until the glaze dipping assembly returns to the vertical position. During the tilting process of the glaze dipping assembly, the glaze slurry in the glaze slurry cavity also penetrates to the surface of the suction cup 43, and the glaze slurry is evenly coated on the bottom of the green body, that is, the green body adsorption part by rotating. When the glazing is completed, the blank selection is stopped, the external vacuum generator stops working, the negative pressure is released, and the worker can easily remove the glazed blank from the suction cup 43, which is very convenient.
