Description

Technical Field

[0001] The present invention relates to the technical field of ceramic art brick production, and particularly to a method for producing ceramic art bricks with variable colors. Background Art

[0002] Ceramic art bricks are a new type of material that applies the expression form of ceramic art to architectural decoration. Ceramic art bricks are generally made of ceramic clay (porcelain clay or purple sand), hand-carved and decorated, and then fired at a high temperature of over 1180 degrees Celsius. They can be in their natural color or glazed, and do not change color after long-term use outdoors. They are an ideal material for landscape art modeling.

[0003] In order to make the ceramic art bricks have colors, glaze powder is sprinkled on the surface of the ceramic art bricks for coloring. In order to achieve the effect that each brick has a different color after the ceramic art bricks are laid, different masses of glaze powder need to be sprinkled on each brick, and a powder sprinkling method and equipment with variable colors need to be developed. Summary of the Invention

[0004] To overcome the technical defects existing in the prior art, the present invention provides a method for producing ceramic art bricks with variable colors, realizing color differences for each brick and variable-color powder sprinkling.

[0005] The technical solution adopted by the present invention is as follows:

[0006] For the method for producing ceramic art bricks with variable colors, a variable-color powder sprinkling system is used for powder sprinkling. The variable-color powder sprinkling system includes a conveying device, a frame, and a powder sprinkling machine. The method includes the following steps:

[0007] S1: The conveying device conveys the brick blanks to the lower side of the powder sprinkling machine;

[0008] S2: Start the powder sprinkling machine to sprinkle powder;

[0009] S3: The powder sprinkling machine moves along the frame, and the moving direction of the powder sprinkling machine reciprocates periodically along the direction perpendicular to the conveying direction of the conveying device. The time for the brick blanks to pass through the lower side of the powder sprinkling machine is greater than the cycle time for the powder sprinkling machine to move along the direction perpendicular to the conveying direction of the conveying device.

[0010] Preferably, the powder sprinkling machine includes a powder sprinkling frame, a powder sprinkling device, a first powder screening device, and a second powder screening device. The powder sprinkling device, the first powder screening device, and the second powder screening device are fixedly installed on the powder sprinkling frame from top to bottom. The powder sprinkling frame slides along the frame, and the moving direction of the powder sprinkling frame is perpendicular to the conveying direction of the conveying device.

[0011] Preferably, the powder sprinkling frame includes two powder sprinkling trolleys. The powder sprinkling trolleys are respectively provided with drive motors and a plurality of walking wheels, and the drive motors drive the walking wheels to move along the frame.

[0012] Preferably, the second powder screening device includes a second sieve plate and a unilateral lifting device. One end of the second sieve plate is placed on the powder spreading trolley, and the unilateral lifting device is installed on the powder spreading trolley corresponding to the other end of the second sieve plate. The unilateral lifting device pulls one end of the second sieve plate to lift and lower.

[0013] Preferably, the unilateral lifting device includes a lifting motor, two lifting mounting plates and two lifting ropes. The lifting motor is installed on the powder spreading trolley through the two lifting mounting plates. Traction holes are provided on the lifting mounting plates. The lifting ropes pass through the corresponding traction holes and are fixed on the second sieve plate. The lifting ropes are respectively fixedly installed at the output end of the lifting motor.

[0016] Preferably, the mesh number of the second sieve plate is greater than that of the first sieve plate.

[0017] The beneficial effects of the present invention are as follows:

[0018] A method for producing ceramic art bricks with variable colors uses a variable-color powder spreading system for powder spreading. The variable-color powder spreading system includes a conveying device, a frame and a powder spreading machine. The method includes the following steps:

[0019] S1: The conveying device conveys the brick blank to the lower side of the powder spreading machine. During the powder spreading process, the conveying device always conveys the brick blank to move, that is, powder spreading and conveying are carried out simultaneously.

[0020] S2: Start the powder spreading machine to carry out powder spreading. It should be noted that before the conveying device conveys the brick blank to the lower side of the powder spreading machine, the powder spreading machine should start working so as to ensure that glaze powder is sprinkled on each brick blank.

[0021] S3: The powder spreader moves along the frame. The moving direction of the powder spreader is a periodic reciprocating motion perpendicular to the conveying direction of the conveying device. The time for the green brick to pass under the powder spreader is greater than the periodic time for the powder spreader to move perpendicular to the conveying direction of the conveying device. During the process of the powder spreader moving perpendicular to the conveying direction of the conveying device, the powder spreading area swings within the green brick area. Moreover, since the time for the green brick to pass under the powder spreader is greater than the periodic time for the powder spreader to move perpendicular to the conveying direction of the conveying device, it is ensured that no green brick will not be powdered, because during the process of the green brick passing under the powder spreader, there will always be a moment when the powder spreader is directly above. It should be noted that for the green bricks in the middle of the conveying device, due to the longer powder spreading time of the powder spreader, the color of the finished product is darker, and the color of the green bricks on both sides of the conveying device is lighter, achieving color difference for each brick and realizing variable-color powder spreading.

[0029] The present invention will be further described below with reference to the drawings:

[0030] As shown in the figure, this embodiment provides a method for producing pottery bricks with variable colors, using a variable-color powder spreading system for powder spreading. The variable-color powder spreading system includes a conveying device 1, a frame 2, and a powder spreader 3. The method includes the following steps:

[0031] S1: The conveying device 1 conveys the green bricks to the lower side of the powder spreader 3. During the powder spreading process, the conveying device 1 always conveys the green bricks while moving, that is, powder spreading and conveying are carried out simultaneously.

[0032] S2: Start the powder spreader 3 to spread powder. It should be noted that before the conveying device 1 conveys the green brick to the lower side of the powder spreader 3, the powder spreader 3 should start working so as to ensure that glaze powder is spread on each green brick.

[0033] S3: The powder spreader 3 moves along the frame 2. The moving direction of the powder spreader 3 is a periodic reciprocating motion perpendicular to the conveying direction of the conveying device 1. The time for the green brick to pass under the powder spreader 3 is greater than the period of the powder spreader 3 moving in the direction perpendicular to the conveying direction of the conveying device 1. During the process of the powder spreader 3 moving in the direction perpendicular to the conveying direction of the conveying device 1, the powder spreading area swings within the area of the green brick. Moreover, since the time for the green brick to pass under the powder spreader 3 is greater than the period of the powder spreader 3 moving in the direction perpendicular to the conveying direction of the conveying device 1, it is ensured that no green brick will fail to be sprinkled with powder. Because during the process of the green brick passing under the powder spreader 3, it will always encounter the moment when the powder spreader 3 is directly above. It should be noted that for the green brick in the middle of the conveying device 1, due to the longer powder spreading time of the powder spreader 3, the color of the finished product is darker, while the color of the green bricks on both sides of the conveying device 1 is lighter, achieving color difference for each brick and realizing variable-color powder spreading.

[0034] The powder spreader 3 includes a powder spreading frame 31, a powder spreading device 32, a first powder screening device 33 and a second powder screening device 34. The powder spreading device 32, the first powder screening device 33 and the second powder screening device 34 are fixedly installed on the powder spreading frame 31 from top to bottom. The powder spreading device 32 is used to store glaze powder. After the powder spreading device 32 starts to spread powder, the powder passes through the first powder screening device 33 and then falls into the second powder screening device 34. After the glaze powder falls onto the first powder screening device 33, it is spread out on the first powder screening device 33 so that the glaze powder can evenly fall from the first powder screening device 33 onto the second powder screening device 34, ensuring that there is powder everywhere on the second powder screening device 34 and avoiding the situation that some green bricks are not sprinkled with powder. The powder spreading frame 31 slides along the frame 2. The powder spreading frame 31 includes two powder spreading trolleys 311. Driving motors 312 and a number of walking wheels are respectively arranged on the powder spreading trolleys 311. The driving motors 312 drive the walking wheels to move along the frame 2. The moving direction of the powder spreading frame 31 is perpendicular to the conveying direction of the conveying device 1. The powder spreading frame 31 drives the powder spreading device 32, the first powder screening device 33 and the second powder screening device 34 to change positions above the conveying device 1 for powder spreading.

[0035] The second powder screening device 34 includes a second sieve plate 341 and a unilateral lifting device 342. One end of the second sieve plate 341 is placed on the powder spreading trolley 311, and the unilateral lifting device 342 is installed on the powder spreading trolley 311 corresponding to the other end of the second sieve plate 341. The unilateral lifting device 342 pulls one end of the second sieve plate 341 to lift and lower. The unilateral lifting device 342 includes a lifting motor 3421, two lifting mounting plates 3422 and two lifting ropes. The lifting motor 3421 is installed on the powder spreading trolley 311 through the two lifting mounting plates 3422. Traction holes are provided on the lifting mounting plates 3422. The lifting ropes pass through the corresponding traction holes and are fixed on the second sieve plate 341. The lifting ropes are respectively fixed on the output end of the lifting motor 3421. The lifting motor 3421 rotates to pull the lifting ropes, thereby driving one end of the second sieve plate 341 to lift and lower. During the process of one end of the second sieve plate 341 lifting and lowering, the glaze powder on the second sieve plate 341 will move towards the lower place, resulting in that the green bricks under the second sieve plate 341 actually cannot obtain the same glaze powder, and thus realizing different glazing colors.

[0036] Two constraint grooves 3111 are provided on the powder spreading trolley 311. The second sieve plate 341 extends into the two constraint grooves 3111. The width of the constraint groove 3111 is greater than the width of the second sieve plate 341. In this way, the constraint groove 3111 can enable the second sieve plate 341 to have the freedom of swinging.

[0037] The powder spreading device 32 is provided with a box body and a vibrator. A plurality of powder spreading holes are provided at the bottom of the box body. The vibrator is installed on the box body. The vibrator is used to apply vibration to the box body to ensure smooth material falling.

[0038] The mesh number of the second sieve plate 341 is greater than that of the first sieve plate. The first sieve plate is used to screen out larger particles to ensure the service life of the second sieve mesh.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
