Description

Technical Field

[0001] This utility model relates to the field of ceramic glazed tile processing technology, and in particular to a three-dimensional printing device for ceramic glazed tiles. Background Technology

[0002] The 3D printing process for ceramic glazed tiles is a key step in enhancing the decorative effect of the product. Its core requirement is to accurately form a pattern with raised and recessed texture on the tile surface. This places stringent demands on the stability, positioning accuracy, and surface cleanliness of the tile blank during the printing process. Currently, the positioning and clamping devices commonly used in the industry still have the following problems in practical applications: In the prior art, such as the "positioning and clamping device for printing ceramic substrates" disclosed in CN223147966U, although the above device can fix the ceramic substrate through mechanical clamping structure and has a certain degree of ease of disassembly, the rigid clamping method it adopts has significant limitations. The clamping force is concentrated on the edge of the brick blank, which can easily cause micro-deformation of glazed bricks, especially thin bricks, and thus cause the printed pattern to deviate from the brick surface reference. The rigid contact between the fixing clamp and the brick surface will leave indentations on the edge, affecting the appearance quality of the product; To address this, a three-dimensional printing device for ceramic glazed tiles is proposed. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the concentrated clamping force acting on the edge of the brick blank in the fixed clamping method, which easily leads to stress concentration, and the hard contact between the fixed clamping device and the brick surface leaving indentations on the edge. Therefore, this invention proposes a three-dimensional printing device for ceramic glazed tiles.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A three-dimensional printing device for ceramic glazed tiles includes a conveyor placed on the ground; The printing press is fixedly connected to the top of the conveyor; A fixing mechanism is installed between the two sides of the conveyor to fix the glazed tiles. The fixing mechanism includes a support plate fixedly connected between the two side frames of the conveyor. Multiple sleeves are symmetrically fixedly connected to the top of the support plate. A through guide rod is inserted into the inside of each sleeve. The top of the multiple guide rods is fixedly connected to the same negative pressure box. A silicone pad is fixedly connected to the top opening face of the negative pressure box. An air extraction hole is opened at the bottom of the negative pressure box. The air extraction hole is connected to an external negative pressure device through a pipeline. A lifting assembly is provided on the top of the support plate to control the lifting of the negative pressure box.

[0005] In one possible design, the lifting assembly includes a cylinder fixedly connected to the top of the support plate, with one end of the cylinder piston rod fixed to the bottom center of the negative pressure box.

[0006] In one possible design, the conveyor includes a motor I, a drive shaft, a driven shaft, a symmetrically arranged frame, and belts. The motor I is fixedly connected to one side of the frame, and one end of the output shaft of the motor I is fixed to the drive shaft of the conveyor. Two conveyor belts are symmetrically fitted around the outer circumference of the drive shaft and the driven shaft of the conveyor. The gap between the two conveyor belts is greater than the width of the negative pressure box, and the width between the two frames of the conveyor matches the width clearance of the glazed tile.

[0007] In one possible design, a roller brush is rotatably connected to the top of the conveyor via a bearing housing, and a motor II is fixedly connected to the top of the conveyor, with one end of the output shaft of motor II fixed to the roller brush.

[0008] In one possible design, a laser emitter and a laser receiver are fixedly connected to adjacent sides of the conveyor frame, respectively. The laser emitter and laser receiver are located below the printing press, and their optical path axes are perpendicular to the conveying direction.

[0009] In one possible design, a PLC controller is fixedly connected to one side of the printing press, and the PLC controller is electrically connected to motor I, the printing press, the cylinder, the laser emitter, and the laser receiver.

[0010] In this application: Motor I drives the active shaft of the conveyor to rotate, which drives the two conveyor belts to run synchronously. The glazed tiles are placed on the conveyor belts and transported with them. Because the width between the two frames of the conveyor is matched with the width of the glazed tiles, the glazed tiles maintain lateral positioning during the transport process, avoiding large displacement. Before the glazed tile reaches the printing station, the roller brush on the top of the conveyor rotates at high speed under the drive of motor II. When the glazed tile passes under the roller brush, the roller brush contacts the tile surface and sweeps away the dust and glaze particles attached to the surface to ensure that the printing surface is clean and to avoid impurities affecting the glaze adhesion effect. When the glazed tile is conveyed to the bottom of the printing machine, it blocks the laser beam emitted by the laser emitter. Because the laser receiver cannot receive the laser signal, it transmits a trigger signal to the PLC controller. After receiving the positioning signal, the PLC controller immediately controls motor I to stop running, the conveyor belt to pause conveying, and at the same time, the cylinder is activated. Its piston rod extends upward, pushing the negative pressure box and silicone pad to rise synchronously. During this process, the guide rod slides along the inner wall of the sleeve to ensure that the negative pressure box rises and falls smoothly until the silicone pad is tightly attached to the bottom of the glazed tile. Then, the air pipe channel of the external negative pressure equipment is opened, and the air in the negative pressure box is extracted through the air extraction hole, so that a negative pressure is formed inside the box. The silicone pad firmly adsorbs the glazed tile with the help of atmospheric pressure, achieving flexible fixation and avoiding deformation or indentation of the tile surface caused by rigid clamping. After the glazed tile is flexibly fixed, the PLC controller sends a start signal to the printer. The printer prints a textured decorative pattern on the surface of the glazed tile according to the preset 3D pattern parameters. The printer is a ceramic inkjet 3D printer, and the model can be the Aisk CW400 3D printer. After printing is completed, the printer sends a completion signal to the PLC controller, which then closes the external negative pressure equipment channel. The pressure inside the negative pressure box returns to normal pressure, and the silicone pad releases its adsorption on the glazed tile. At the same time, the cylinder piston rod retracts, driving the negative pressure box and silicone pad to descend and reset. The negative pressure box passes through the gap between the two conveyor belts to avoid interference with the conveyor belts. Finally, motor I restarts, and the conveyor belt transports the printed glazed tile to the next process, and the device enters the next working cycle.

[0011] Beneficial effects: In this utility model, the ceramic glazed tile three-dimensional printing device, through the combined use of components such as negative pressure box, silicone pad, and air extraction hole, the flexible adsorption structure of negative pressure box and silicone pad evenly distributes the fixing force on the bottom of glazed tile, greatly increasing the force-bearing area. The opening of the external negative pressure equipment channel allows a stable negative pressure to be formed inside the negative pressure box. When the silicone pad adheres to the tile surface, it generates surface contact adsorption force, avoiding local stress concentration, reducing the amount of deformation caused by clamping, and solving the problem of pattern misalignment. In this utility model, the ceramic glazed tile three-dimensional printing device uses components such as a negative pressure box, silicone pad, and exhaust hole in combination. The silicone pad is used as the contact medium. Its elastic material can buffer the impact force during the adsorption process and there is no rigid friction when it is attached to the tile surface. At the same time, the negative pressure adsorption force is flexibly transmitted through the silicone pad and will not form mechanical indentations on the tile surface. In this invention, a stable negative pressure is formed inside the negative pressure box by an external negative pressure device. When the silicone pad is attached to the brick surface, it generates a surface contact adsorption force, which avoids local stress concentration. At the same time, the negative pressure adsorption force is flexibly transmitted through the silicone pad, and no mechanical indentation is formed on the brick surface. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In one implementation case, refer to Figures 1-4 A three-dimensional printing apparatus includes: a conveyor 1 placed on the ground; In this embodiment, the printing press 3 is fixedly connected to the top of the conveyor 1; In particular, a fixing mechanism, installed between the two sides of the conveyor 1, is used to fix the glazed tiles. The fixing mechanism includes a support plate 6 fixedly connected between the two side frames of the conveyor 1. Multiple sleeves 7 are symmetrically fixedly connected to the top of the support plate 6. Each sleeve 7 has a through guide rod 5 inserted inside. The two work together to form a guide structure to ensure that the negative pressure box 9 remains stable during lifting and lowering, avoiding tilting or shaking. The top of the multiple guide rods 5 is fixedly connected to the same negative pressure box 9. A silicone pad 8 is fixedly connected to the top opening face of the negative pressure box 9, which contacts the bottom of the glazed tile. When the negative pressure is applied, the adsorption force generated by the negative pressure can be evenly transferred to the brick surface, avoiding stress concentration and rigid contact with the brick surface, thus preventing indentation. The bottom of the negative pressure box 9 is provided with an air extraction hole 11, which is connected to an external negative pressure device through a pipeline. The negative pressure device is a negative pressure pump. The opening and closing of the pipeline connecting the negative pressure pump and the negative pressure box 9 is controlled by a solenoid valve. When the external negative pressure device channel is opened, the air inside the negative pressure box 9 is extracted, so that a stable negative pressure is formed inside the box, providing power for adsorbing and fixing the glazed tiles. The top of the support plate 6 is provided with a lifting component for controlling the lifting and lowering of the negative pressure box 9.

[0019] It should be noted that the lifting assembly includes a cylinder 10 fixedly connected to the top of the support plate 6. One end of the piston rod of the cylinder 10 is fixed to the bottom center of the negative pressure box 9. The extension and retraction of the piston rod drives the negative pressure box 9 to rise and fall, thereby realizing the contact or separation between the silicone pad 8 and the glazed tile.

Two conveyor belts 101 are symmetrically sleeved on the outer circumference of the drive shaft and the driven shaft of the conveyor 1. The gap between the two conveyor belts 101 is greater than the width of the negative pressure box 9. The width between the two frames of the conveyor 1 is matched with the width gap of the glazed tile to form a lateral limit on the glazed tile, preventing large lateral deviation during the conveying process and ensuring the stability of the glazed tile conveying path.

[0022] In this implementation case, a roller brush 2 is rotatably connected to the top of the conveyor 1 via a bearing seat, and a motor II 4 is fixedly connected to the top of the conveyor 1. One end of the output shaft of the motor II 4 is fixed to the roller brush 2. The roller brush 2 rotates under the drive of the motor II 4, which can clean the dust and glaze particles on the surface of the glazed tile and ensure the cleanliness of the printed surface.

The laser emitter 12 and the laser receiver 14 are located below the printing machine 3 and their optical path axes are perpendicular to the conveying direction. The laser emitter 12 emits a laser beam and the laser receiver 14 receives the laser. When the glazed tile arrives at the printing station, it blocks the laser beam. The laser receiver 14 transmits the signal to the PLC controller 13 to realize the positioning detection of the glazed tile.

[0024] It should be noted that a PLC controller 13 is fixedly connected to one side of the printing machine 3. The PLC controller 13 is electrically connected to the motor I 102, the printing machine 3, the cylinder 10, the laser transmitter 12, and the laser receiver 14.
