Description

Technical Field

[0001] This invention relates to the field of ceramic tile glaze spraying technology, specifically a ceramic tile glaze spraying process and equipment. Background Technology

[0002] As an important building and decorative material, ceramic tiles typically require glazing to enhance their aesthetics, stain resistance, and durability. Traditional glazing processes often involve continuously conveying tiles via conveyor belts, using fixed or moving spray nozzles for glaze application. However, this method has significant limitations in actual production: firstly, during operation, the conveyor belt is prone to slight displacement or vibration of the tiles due to mechanical vibration, speed fluctuations, or uneven belt tension, affecting the uniformity and consistency of the glaze application and leading to problems such as uneven glaze thickness, missed areas at the edges, or glaze accumulation; secondly, traditional clamping or positioning methods rely heavily on manual or simple mechanical fixation, making it difficult to achieve rapid, precise, and stable clamping and release of tiles in high-speed continuous operations. This is especially problematic in the production of large-size or thin tiles, where unstable clamping can easily cause tile breakage or positional displacement, further reducing production yield and efficiency.

[0003] Furthermore, existing spraying equipment often lacks a mechanism for dynamically stabilizing the tiles during the spraying process. The tiles are in a "free" or "semi-fixed" state during both the conveying and spraying stages, making it difficult to completely isolate them from the effects of external vibrations and transmission errors. Although some solutions attempt to use pneumatic or electric grippers with independent drive mechanisms to grasp and move the tiles, their structures are complex and costly, and the coordination and reliability of the gripping and releasing actions remain insufficient. Especially in cyclical operations, it is difficult to achieve an efficient and continuous automated gripping-spraying-release process.

[0004] Therefore, there is an urgent need for a glaze spraying process and equipment that can achieve stable clamping, precise positioning and automatic release during the conveying and spraying of ceramic tiles, in order to overcome the problems of uneven glaze and low production efficiency caused by vibration, inaccurate positioning and unreliable clamping in the existing technology, so as to meet the needs of large-scale production of high-quality ceramic tiles. Summary of the Invention

[0005] The purpose of this invention is to provide a ceramic tile glaze spraying process and equipment in order to achieve uniform spraying of ceramic tiles.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a ceramic tile glaze spraying device, comprising a base, a first conveyor belt at one end of the base, and a second conveyor belt at the other end of the base. Ceramic tiles are conveyed to the base via the first conveyor belt, and the sprayed ceramic tiles are conveyed away via the second conveyor belt. Side plates are symmetrically fixedly connected to the top of the base, and a horizontal plate is fixedly connected to the top of the side plates. A nozzle for spraying glaze is installed on the outer wall of the horizontal plate, and the ceramic tiles are moved by a moving mechanism.

[0007] As a further embodiment of the present invention: the moving mechanism includes a T-shaped plate, which is symmetrically fixedly connected to the top of the base and located on one side of the side plate. A movable seat is slidably connected to the outer wall of the T-shaped plate. The bottom end of the movable seat has a T-shaped groove for the T-shaped plate to slide. A motor is installed at one end of the base. A threaded rod is connected to the output end of the motor. A U-shaped frame extending to the top of the base is slidably connected inside the base. The threaded rod passes through the U-shaped frame. A first spur gear is rotatably connected to the top of the U-shaped frame. The outer wall of the first spur gear contacts both the side plate and the movable seat. The two movable seats clamp the ceramic tile through a clamping mechanism.

[0008] As a further embodiment of the present invention: the clamping mechanism includes a fixed frame, which is symmetrically fixedly connected to one top end of the base. A fixed plate is symmetrically fixedly connected to the other top end of the base. A groove is formed on one side of the fixed plate at the top of the base. Rotating grooves are symmetrically formed at the bottom end of the movable seat. A rotating plate is rotatably connected to the inner wall of the rotating groove. A rubber block is fixedly connected to one end of the rotating plate. A rotating rod is fixedly connected to the top of the rotating plate. A ratchet is fixedly connected to the outer wall of the rotating rod, and the outer wall of the rotating rod is fixedly located above the ratchet. A second spur gear is fixedly connected to the movable seat. A torsion spring is connected between the second spur gear and the outer wall of the rotating rod. A locking block is slidably connected inside the movable seat to one side of the ratchet. A spring is connected between the locking block and the movable seat. A connecting rod is rotatably connected to the outer wall of the locking block. A vertical rod is rotatably connected to one end of the connecting rod. The bottom end of the vertical rod extends to the bottom end of the movable seat, and the top end of the vertical rod extends to the top of the movable seat. A displacement plate is slidably connected inside the movable seat to the outer wall of the second spur gear. The displacement plate extends out of the movable seat.

[0009] As a further embodiment of the present invention: the outer wall of the U-shaped frame is provided with a threaded hole, which matches the threaded rod.

[0010] As a further embodiment of the present invention: the outer walls of both the side plate and the movable seat are provided with a first tooth groove, and the first tooth groove meshes with the first spur gear.

[0011] As a further embodiment of the present invention: the outer wall of the T-shaped plate is in contact with the inner wall of the T-shaped groove.

[0012] As a further embodiment of the present invention: one end of the locking block engages with the ratchet.

[0013] As a further embodiment of the present invention: the outer wall of the displacement plate is provided with a second tooth groove, which meshes with the second spur gear.

[0014] As a further embodiment of the present invention: the top and bottom ends of the vertical rod are provided with semi-circular surfaces; the end of the displacement plate extending from the movable seat is provided with an inclined surface.

[0015] A ceramic tile glaze spraying equipment spraying process includes the following steps: Step 1, Loading and Clamping: Start the first conveyor belt to transport the tile to be sprayed to a fixed position at one end of the base; simultaneously start the motor to drive the threaded rod to rotate, which in turn moves the U-shaped frame and the first spur gear toward the tile; the first spur gear meshes with the first tooth groove on the side plate and the movable seat, causing the two movable seats on both sides to move synchronously toward the sides of the tile along the T-shaped plate; when the movable seats move to the sides of the tile, the top of the vertical rod contacts the fixed frame and is pressed down, which pulls the locking block away from the ratchet through the connecting rod, and the torsion spring releases the torque, driving the second spur gear and the rotating rod to rotate, causing the rotating plate to rotate the rubber block outward and clamp the sides of the tile.

[0016] Step 2, Spraying and Transfer: After clamping, the motor reverses and drives the movable seat to move the tile at a constant speed toward the second conveyor belt; during the movement, the nozzle sprays glaze downwards evenly to complete the tile surface spraying; at this time, the locking block re-engages with the ratchet under the action of the spring, locking the position of the rotating plate to prevent the tile from loosening during movement.

[0017] Step 3, Unloading and Resetting: When the front end of the tile moves above the second conveyor belt, the bottom end of the vertical rod detaches from the base surface. Then, the displacement plate contacts the fixed plate and is pushed inward. The second tooth groove drives the second spur gear to rotate, causing the rotating plate to rotate back into the rotating groove, and the rubber block separates from the tile. The tile falls onto the second conveyor belt and is sent away. The movable seat continues to reset and move, ready for the clamping and spraying cycle of the next tile.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. It achieves stable clamping and precise positioning of tiles throughout the spraying process.

[0019] This invention, through the coordinated action of a moving mechanism and a clamping mechanism, ensures that the ceramic tile remains clamped by the movable seat throughout the entire process from receiving it from the first conveyor belt, spraying it, to transferring it to the second conveyor belt. The clamping mechanism employs a ratchet-block-torsion spring linkage design, coupled with a contact triggering mechanism between the vertical rod and the fixed frame and base, to achieve automatic execution and locking of the clamping action. This effectively avoids ceramic tile displacement caused by vibration of traditional conveyor belts, ensuring the high stability of the ceramic tile position during glazing, thereby significantly improving the uniformity of the glaze surface and the integrity of edge coverage.

[0020] 2. It has improved the automation level and production continuity of the spraying operation.

[0021] This equipment utilizes a transmission system driven by a motor through a threaded rod, a U-shaped frame, and a first spur gear to achieve the reciprocating motion of the movable seat on the T-shaped guide rail. Combined with the automatic clamping and releasing function of the clamping mechanism, it forms a fully automated cycle process of "feeding-clamping-transferring-spraying-releasing-resetting". It enables efficient and continuous processing of ceramic tiles without manual intervention, significantly reducing labor intensity and improving production cycle time and equipment utilization.

[0022] 3. The reliability and adaptability of the clamping mechanism have been enhanced.

[0023] The combination of the rotating plate and rubber block in the clamping mechanism can adapt to the clamping needs of tiles of different thicknesses. The rubber material provides sufficient clamping force while avoiding damage to the tile surface. The locking mechanism of the ratchet and the locking block ensures that the clamping state is irreversible during the transfer process, preventing the tiles from loosening or falling off during movement. The trigger release design of the vertical rod and the displacement plate ensures that the tiles can be smoothly and automatically released when they reach the second conveyor belt, avoiding jamming or collision and improving the reliability of the system operation.

[0024] 4. It has a compact structure, stable operation, and is easy to integrate into existing production lines.

[0025] The overall structure of this equipment is based on a modular design of the base, side plates, and cross plates. The moving and clamping mechanisms are integrated within a limited space, resulting in a rational layout and clear motion trajectory. The sliding fit between the T-shaped guide rail and the movable seat ensures smooth movement, while the motor-threaded rod transmission method provides high control precision and fast response. Furthermore, the first and second conveyor belts can be connected to existing production line conveyor systems, facilitating modification and integration, and demonstrating good engineering applicability and promotional value.

[0026] In summary, this invention effectively solves the problems of uneven glaze and low production efficiency caused by vibration and unstable clamping in traditional processes by systematically optimizing the positioning, clamping and transfer methods of ceramic tiles during the spraying process. It achieves high uniformity, high automation and high reliability in ceramic tile glaze spraying production, and has obvious technological advantages and practical benefits.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0031] Please see Figures 1 to 8 In this embodiment of the invention, a ceramic tile glaze spraying device includes a base 1, a first conveyor belt 2 at one end of the base 1, and a second conveyor belt 3 at the other end of the base 1. Ceramic tiles are conveyed onto the base 1 via the first conveyor belt 2, and the sprayed ceramic tiles are conveyed away via the second conveyor belt 3. Side plates 4 are symmetrically fixedly connected to the top of the base 1, and a horizontal plate 5 is fixedly connected to the top of the side plates 4. A nozzle 6 for spraying glaze is installed on the outer wall of the horizontal plate 5. The ceramic tiles are moved via a moving mechanism 7, which includes a T-shaped plate 702 symmetrically fixedly connected to the top of the base 1 and located on the side plates 4. On one side, a movable seat 701 is slidably connected to the outer wall of the T-shaped plate 702. The bottom end of the movable seat 701 is provided with a T-shaped groove 703 for the T-shaped plate 702 to slide. A motor 704 is installed at one end of the base 1. A threaded rod 705 is connected to the output end of the motor 704. A U-shaped frame 706 extending to the top of the base 1 is slidably connected inside the base 1. The threaded rod 705 passes through the U-shaped frame 706. A first spur gear 707 is rotatably connected to the top of the U-shaped frame 706. The outer wall of the first spur gear 707 is in contact with both the side plate 4 and the movable seat 701. The two movable seats 701 clamp the tile through the clamping mechanism 8.

[0032] In this embodiment: The motor 704 is started, and its operation drives the threaded rod 705 to rotate. The rotation of the threaded rod 705 causes the U-shaped frame 706 to shift. The shift of the U-shaped frame 706 causes the first spur gear 707 to shift synchronously. The first spur gear 707 shifts along the side plate 4, thus rotating. Simultaneously, the first spur gear 707 shifts, causing the movable seat 701 to shift, such that the distance of displacement of the movable seat 701 is twice the distance of displacement of the first spur gear 707. At this time, the T-shaped plate 702 and the T-shaped groove 7... 03. Relative sliding is performed to ensure the stability of the movable seat 701. The first conveyor belt 2 transports the tile to one end of the base 1. The two movable seats 701 move closer to the tile and are displaced. The movable seats 701 automatically clamp the tile through the cooperation of the parts in the clamping mechanism 8. The movable seats 701 move towards the second conveyor belt 3, and the tile moves synchronously. During the movement of the tile, the spray head 6 is connected to the glaze supply system through a solenoid valve. When the movable seats 701 move the tile to the spraying area, the control system triggers the spray head to open, achieving uniform spraying. The displacement of the movable seats 701 moves the tile onto the second conveyor belt 3, automatically releasing the tile. The second conveyor belt 3 then transports the sprayed tile away. This design facilitates stable displacement of the tile during the spraying process, ensuring that the glaze is evenly sprayed onto the tile.

[0033] Please refer to this carefully. Figures 4 to 8 The clamping mechanism 8 includes a fixed frame 801, which is symmetrically fixedly connected to one top end of the base 1. A fixed plate 802 is symmetrically fixedly connected to the other top end of the base 1. A groove 803 is formed on one side of the fixed plate 802 at the top of the base 1. A rotating groove 815 is symmetrically formed at the bottom end of the movable seat 701. A rotating plate 805 is rotatably connected to the inner wall of the rotating groove 815. A rubber block 804 is fixedly connected to one end of the rotating plate 805. A rotating rod 806 is fixedly connected to the top of the rotating plate 805. A ratchet 807 is fixedly connected to the outer wall of the rotating rod 806. A second spur gear 81 is fixedly connected to the outer wall of the rotating rod 806 above the ratchet 807. 2. A torsion spring 813 is connected between the second spur gear 812 and the movable seat 701 on the outer wall of the rotating rod 806. A locking block 808 is slidably connected inside the movable seat 701 on one side of the ratchet 807. A spring 809 is connected between the locking block 808 and the movable seat 701. A connecting rod 810 is rotatably connected to the outer wall of the locking block 808. A vertical rod 811 is rotatably connected to one end of the connecting rod 810. The bottom end of the vertical rod 811 extends to the bottom end of the movable seat 701, and the top end of the vertical rod 811 extends to the top of the movable seat 701. A displacement plate 814 is slidably connected inside the movable seat 701 on the outer wall of the second spur gear 812. The displacement plate 814 extends out of the movable seat 701.

[0034] In this embodiment: when the movable seat 701 moves toward the ceramic tile on the first conveyor belt 2, the rotating plate 805 rotates into the rotating groove 815, the locking block 808 is displaced by the elastic force of the spring 809 to engage the ratchet 807, and the torsion spring 813 is in a deformed state.

[0035] When the movable seat 701 moves to both sides of the tile, the bottom end of the vertical rod 811 separates from the top end of the base 1, and the top end of the vertical rod 811 contacts the fixed frame 801. The fixed frame 801 pushes the vertical rod 811 to move. The displacement of the vertical rod 811 drives the locking block 808 to move through the connecting rod 810, which squeezes the spring 809. The locking block 808 moves and separates from the ratchet 807. At this time, the second spur gear 812 rotates under the torque of the torsion spring 813. The rotation of the second spur gear 812 drives the rotating rod 806 and the ratchet 807 to rotate synchronously. The rotation of the rotating rod 806 drives the rotating plate 805 to rotate. The rotation of the rotating plates 805 on both sides clamps the tile through the rubber block 804. The rotation of the second spur gear 812 drives the displacement plate 814 to move. One end of the displacement plate 814 moves out of the movable seat 701.

[0036] When the movable seat 701 moves toward the second conveyor belt 3, the movable seat 701 drives the tile to move synchronously through the rotating plate 805. At this time, the fixed frame 801 separates from the vertical rod 811, and the locking block 808 is displaced by the elastic force of the spring 809 and engages with the ratchet 807. At the same time, the bottom end of the vertical rod 811 contacts the top end of the base 1. At this time, the vertical rod 811 has no space to move downward, so that the locking block 808 and the ratchet 807 remain engaged, thereby fixing the ratchet 807, the rotating rod 806 and the rotating plate 805 to prevent loosening during the clamping of the tile.

[0037] When one end of the tile moves onto the second conveyor belt 3, the bottom end of the vertical rod 811 moves above the groove 803 and separates from the base 1. Then, the movable seat 701 continues to move until the displacement plate 814 contacts the fixed plate 802. The displacement plate 814 is displaced by the force, and the displacement of the displacement plate 814 drives the second spur gear 812 to rotate, causing the torsion spring 813 to twist. The rotation of the second spur gear 812 drives the rotating plate 805 to rotate into the rotating groove 815 through the rotating rod 806, separating from the tile. After separation, the tile is conveyed away by the second conveyor belt 3. The movable seat 701 then moves towards the first conveyor belt 2 again. This design facilitates the movable seat 701 to automatically clamp and fix the tile on the first conveyor belt 2, and prevents the tile from loosening during the movement. At the same time, when the tile moves onto the second conveyor belt 3, it can automatically release the tile.

[0038] It should be noted that the motor 704 is controlled to rotate forward and backward via a PLC or sensor, enabling the movable seat to move forward, backward, and stop.

[0039] Please refer to this carefully. Figures 1 to 4 The outer wall of the U-shaped frame 706 is provided with a threaded hole, which matches the threaded rod 705.

[0040] In this embodiment: the motor 704 drives the threaded rod 705 to rotate, the rotation of the threaded rod 705 drives the U-shaped frame 706 to move, and the movement of the U-shaped frame 706 drives the first spur gear 707 to perform synchronous displacement operation.

[0041] Please refer to this carefully. Figures 1 to 4 The outer walls of the side plate 4 and the movable seat 701 are both provided with first tooth grooves, which mesh with the first spur gear 707.

[0042] In this embodiment: the first spur gear 707 moves along the side plate 4 and rotates. While the first spur gear 707 moves, it rotates, thereby driving the movable seat 701 to move, so that the distance of the movable seat 701 is twice the distance of the first spur gear 707.

[0043] Please refer to this carefully. Figures 1 to 4 The outer wall of the T-shaped plate 702 fits against the inner wall of the T-shaped groove 703.

[0044] In this embodiment, the T-shaped plate 702 slides within the T-shaped groove 703, allowing the movable seat 701 to slide stably.

[0045] Please refer to this carefully. Figures 4 to 8 One end of the locking block 808 engages with the ratchet 807.

[0046] In this embodiment: the locking block 808 is displaced by the elastic force of the spring 809 to engage the ratchet 807, so that the ratchet 807 can only rotate in one direction.

[0047] Please refer to this carefully. Figures 4 to 8 The outer wall of the displacement plate 814 is provided with a second tooth groove, which meshes with the second spur gear 812.

[0048] In this embodiment: the rotation of the second spur gear 812 drives the displacement plate 814 to move, so that one end of the displacement plate 814 moves out of the movable seat 701.

[0049] Please refer to this carefully. Figures 4 to 8 The top and bottom of the vertical rod 811 are provided with semi-circular surfaces; the end of the displacement plate 814 extending out of the movable seat 701 is provided with an inclined surface.

[0050] In this embodiment: when the vertical rod 811 contacts the fixed frame 801, the fixed frame 801 contacts the semi-circular surface, pushing the vertical rod 811 downward to perform a displacement operation.

[0051] A ceramic tile glaze spraying equipment spraying process includes the following steps: Step 1, Loading and Clamping: Start the first conveyor belt 2 to transport the tile to be sprayed to a fixed position at one end of the base 1; at the same time, start the motor 704 to drive the threaded rod 705 to rotate, which in turn drives the U-shaped frame 706 and the first spur gear 707 to move towards the tile; the first spur gear 707 meshes with the first tooth groove on the side plate 4 and the movable seat 701, which drives the movable seats 701 on both sides to move towards the sides of the tile along the T-shaped plate 702; when the movable seats 701 move to the sides of the tile, the top of the vertical rod 811 contacts the fixed frame 801 and is pressed down, which pulls the locking block 808 out of the ratchet 807 through the connecting rod 810, and the torsion spring 813 releases the torque, which drives the second spur gear 812 and the rotating rod 806 to rotate, so that the rotating plate 805 drives the rubber block 804 to flip outward and clamp the sides of the tile; Step 2, Spraying and Transfer: After clamping, the motor 704 reverses and drives the movable seat 701 to move the tile at a constant speed toward the second conveyor belt 3; during the movement, the nozzle 6 sprays glaze downwards evenly to complete the tile surface spraying; at this time, the locking block 808 is re-engaged into the ratchet 807 under the action of the spring 809, locking the position of the rotating plate 805 to prevent the tile from loosening during the movement; Step 3, Unloading and Resetting: When the front end of the tile moves above the second conveyor belt 3, the bottom end of the vertical rod 811 detaches from the surface of the base 1. Then, the displacement plate 814 contacts the fixed plate 802 and is pushed inward to slide. The second tooth groove drives the second spur gear 812 to rotate, causing the rotating plate 805 to rotate back into the rotating groove 815. The rubber block 804 separates from the tile. The tile falls onto the second conveyor belt 3 and is sent away. The movable seat 701 continues to reset and move, preparing for the clamping and spraying cycle of the next tile.
