Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramic processing technology, and in particular to a glazing machine for ceramic processing. Background Technology
[0002] ① Most current automatic ceramic glazing equipment adopts a single-degree-of-freedom swing arm structure, in which the nozzle is driven by a single rotary motor to swing back and forth in a fixed plane. This design results in a single movement path for the nozzle, which cannot effectively handle ceramic workpieces with complex curvatures (such as relief vases or irregularly shaped tea sets), and it is especially difficult to uniformly cover grooved areas and negative angle areas, resulting in glaze accumulation or missed spraying defects at the turning points.
[0003] ② To address the aforementioned issues, the existing improvement solution adds a second-stage swing motor to the end of the support arm, enabling the spray head to achieve dual-axis movement capabilities in both horizontal and pitch directions. This solution allows the spray head to tilt and enter the inner cavity of the ceramic wine bottle for spraying, improving the inner wall coverage area compared to traditional single-joint equipment. Its core improvement lies in the fact that the two-stage motors work together to form a composite motion trajectory, utilizing pitch angle adjustment to overcome the planar limitations of single-axis movement.
[0004] ③ Although the dual-axis structure enhances the nozzle's flexibility, the newly added pitch motor, installed as a cantilever, significantly reduces the rigidity of moving parts. During high-speed operation, the cantilever section generates high-frequency vibrations, forcing glaze mist particles to scatter off their preset trajectories. Simultaneously, the exposed motor drive shaft is continuously enveloped by glaze mist, and the hardened, clump-like glaze gradually intrudes into the bearing clearances, causing transmission jamming. Ultimately, this leads to a decline in equipment accuracy and an increased failure rate. The root cause of this defect lies in the lack of dynamic stability in the moving mechanism and the ineffective protection of the core transmission components. Utility Model Content
[0005] The purpose of this utility model is to provide a glazing machine for ceramic processing, which solves the dual technical problems of dynamic instability of the motion mechanism and accumulation of glaze on the transmission shaft caused by the cantilever installation of the dual-shaft structure.
[0006] To achieve the above objectives, this utility model provides a glazing spraying machine for ceramic processing, including a support plate. A first motor is bolted to one side of the support plate, and the output end of the first motor is connected to a first rotating plate via a shaft passing through the support plate. A second motor is bolted to the end of the first rotating plate away from the first support plate, and the output end of the second motor is connected to the second rotating plate via a shaft passing through the first rotating plate. A third motor is bolted to the end of the second rotating plate away from the second motor. A spray head is fixedly installed at the output end of the third motor via a shaft passing through the second rotating plate and a support sleeve. The support sleeve is fixedly installed on the side of the second rotating plate opposite to the third motor, and the support sleeve is nested around the outer periphery of the output shaft of the third motor to improve the rotational stability of the shaft and prevent paint adhesion.
[0007] The support plate is fixedly installed on the top wall inside the protective frame, the protective frame is installed on the base by bolts, and a fixing plate is fixedly installed at the bottom of the base.
[0008] Among them, multiple sets of diagonal bracing plates are fixedly installed between the base and the fixing plate, and four sets of fixing holes are opened at the four corners of the fixing plate. The fixing holes are used for bolts to pass through so that the whole is fixed to the ground.
[0009] The base has an opening door on the side away from the fixed plate via a hinge. A drive motor is vertically mounted on the top wall inside the base via bolts. The output end of the drive motor passes through the base and is connected to the rotating box via a coupling.
[0010] The rotating box is rotatably mounted on the top of the base, and a box cover is bolted to the top of the box cover. Two rotating motors are bolted to the bottom two sides of the box cover inside the rotating box.
[0011] The output end of the rotating motor is connected to the rotating disk through the box cover via a shaft. A rubber block is installed on the top of the rotating disk by bolts. A metal skeleton is embedded inside the rubber block to make the rubber block structure stable.
[0012] This utility model discloses a glazing machine for ceramic processing. A support plate serves as the basic load-bearing component. A first motor is fixed to one side of the support plate with bolts. The output shaft of the first motor passes through the support plate and connects to a first rotating plate, giving the first rotating plate a horizontal rotational degree of freedom. A second motor is installed at the end of the first rotating plate away from the support plate with bolts. The output shaft of the second motor passes through the first rotating plate and connects to the second rotating plate, giving the second rotating plate the ability to adjust its pitch angle. A third motor is fixed to the end of the second rotating plate with bolts. The output shaft of the third motor passes through the second rotating plate and the support sleeve in sequence and drives the nozzle to rotate. The support sleeve is tightly nested around the outer circumference of the output shaft of the third motor and its two ends are respectively fixed to the second rotating plate and the housing of the third motor.
[0013] This structure forms a three-stage rigid motion chain: the horizontal rotation of the first rotating plate establishes the basic orientation of the nozzle; the pitch adjustment of the second rotating plate expands the longitudinal coverage; and the third motor achieves precise nozzle positioning through the shaft system constrained by the support sleeve. During operation, the support sleeve provides radial support and physical sealing to the high-speed rotating shaft, suppressing trajectory deviation caused by shaft swaying and preventing glaze from intruding into the transmission system. This achieves three technical effects simultaneously: the coordinated motion of three degrees of freedom in space enables the nozzle to accurately cover the complex curved surfaces and negative angle areas of the ceramic irregular part; the nested support sleeve eliminates the vibration transmission of the cantilever structure, thus ensuring the stability of the nozzle's motion trajectory; and the fully enclosed shaft protection prevents the hardening and accumulation of glaze, thereby eliminating transmission system jamming.

Detailed Implementation
[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0021] Please see Figures 1-4 .
[0022] This utility model provides a glazing machine for ceramic processing. A rotating motor 118 drives a rotating disk 119 to rotate via a transmission shaft inside a housing cover 117, ensuring uniform glazing of all surfaces of the ceramic body. A metal frame embedded inside a rubber block 120 provides structural rigidity support for the rotating disk 119, preventing deformation during high-speed rotation. A support plate 101 is installed on the top wall of a protective frame 109 fixed to the top of the base 110 by bolts. A first motor 102 is bolted to the side of the support plate 101, and its output shaft passes through the support plate 101 and connects to a first rotating plate 103 to achieve horizontal rotation. A second motor 104... The first rotating plate 103 is bolted to one end away from the support plate 101. Its output shaft passes through the first rotating plate 103 and connects to the second rotating plate 105 to generate pitch angle adjustment. The third motor 106 is bolted to one end of the second rotating plate 105 away from the second motor 104. Its output shaft passes through the second rotating plate 105 and is rigidly connected to the nozzle 108. The support sleeve 107, nested around the outer circumference of the output shaft, is fixedly installed on the mounting surface of the second rotating plate 105 opposite to the third motor 106. The concentric positioning of the rotating shaft by the support sleeve 107 eliminates the problems caused by high-viscosity glaze spraying. Radial vibration occurs when the operator controls the first motor 102 and the second motor 104 to work together. The first rotating plate 103 and the second rotating plate 105 deflect in tandem, causing the nozzle 108 to move along a spatial spherical trajectory. The third motor 106 independently controls the rotation of the nozzle 108 to ensure that the glaze cone angle accurately covers the curved surface of the ceramic body. At the same time, the protective frame 109 blocks glaze splashes and protects the external environment. The fixing plate 111 installed at the bottom of the base 110 is fastened to the foundation with bolts through fixing holes 113 at the four corners. Multiple sets of diagonal bracing plates 112 welded between the base 110 and the fixing plate 111 improve the overall torsional strength. The base 110 can be opened from the side via a hinged door 114 for maintenance of the rotating box 116. The top cover 117 of the rotating box 116 provides a mounting surface for the rotating motor 118. This process enables the nozzle 108 to achieve three-dimensional positioning without dead angles through the compound movement of the three rotating plates. At the same time, the support sleeve 107 provides stable support for the high-speed rotating shaft to ensure uniform glaze thickness. The composite structure of the internal metal skeleton and external elastomer of the rubber block 120 achieves the dual functions of anti-slip fixation and buffer protection for the ceramic body. Overall, it meets the high-precision glazing process requirements of irregularly shaped ceramic products.
[0023] Working principle: When the machine starts, the drive motor 115 first drives the rotating box 116 to rotate as a whole. The rotating box 116 is rigidly connected to the drive motor 115 through a spline coupling to ensure that the power transmission is smooth. At this time, the two rotating motors 118 installed in the rotating box 116 work synchronously, driving the upper rotating disk 119 to rotate through the shaft passing through the box cover 117. The rubber block 120 with a metal frame firmly clamps the ceramic workpiece. The metal frame provides rigid support to prevent the rubber from deforming under force, while the rubber layer absorbs rotational vibration to ensure that the ceramic workpiece is stable during operation. During the process, a stable posture is maintained; while the workpiece rotates stably, the positioning system starts in a three-stage linkage; the first motor 102 drives the first rotating plate 103 on the support plate 101 to rotate horizontally, the second motor 104 drives the second rotating plate 105 to adjust the pitch angle, and the third motor 106 finally precisely controls the orientation of the nozzle 108 through the shaft inside the support sleeve 107; the support sleeve 107 is tightly nested around the outer periphery of the output shaft of the third motor 106, and its exterior is coated with a polytetrafluoroethylene coating, which physically isolates the shaft from the coating and effectively suppresses radial runout at the shaft end. This significantly reduces the risk of glaze adhesion. The three-stage motors form an orthogonal kinematic chain in the spatial coordinate system. When the first rotating plate 103 provides lateral rotational freedom, the second rotating plate 105 achieves longitudinal tilt adjustment, and the third motor 106 drives the nozzle 108 to complete precise axial positioning, the nozzle 108 can cover the rotating workpiece with a three-dimensional trajectory within a high-precision range. The protective frame 109 tightly encloses the entire spraying area, blocking glaze mist diffusion, while the diagonal bracing plate 112 between the base 110 and the fixed plate 111 significantly reduces the vibration transmission rate of the equipment. The anchoring of the fixed hole 113 bolts ensures stable operation of the whole machine; the opening and closing door 114 provides a convenient maintenance passage when the machine is stopped, for cleaning the inner wall of the support sleeve 107 and replacing the nozzle 108; the solution ultimately achieves dual technical effects: for the workpiece, the metal skeleton rubber block 120 and the dual rotating motor 118 drive to achieve constant torque stable clamping; for the spraying system, the three-stage motor works in coordination with the support sleeve 107 for protection, so that the nozzle 108 can achieve precise positioning of multiple degrees of freedom in space while suppressing vibration and preventing contamination, and the glaze layer on the surface of the ceramic parts can achieve a uniform coverage effect.
