Description

Technical Field

[0001] This invention relates to the field of fabric making apparatus, and more particularly to a fabric making method, apparatus, and application for improving the accuracy of digital fabric making. Background Technology

[0002] The existing fabric manufacturing process generally involves first applying the corresponding color powder to the belt according to the pattern as needed, thereby forming the preset pattern. However, the existing powder controls the output position of the printhead according to the preset pattern layer. Due to the characteristics of the powder, the printhead printing accuracy is relatively rough, which may result in missing textures, colors, etc. of the fabric, thus reducing the fabric accuracy. Summary of the Invention

[0003] The purpose of this invention is to propose a method for improving the accuracy of digital fabric application. The method first enlarges a preset pattern, then designs a fabric path based on the enlarged pattern, and then adjusts the included angle α and slows down the conveying speed of the conveying surface so that the nozzle applies the original size pattern with a new fabric path.

[0004] The present invention also proposes a fabric device for improving the accuracy of digital fabric, which includes: a pattern processing module, a conveying device, and a printhead.

[0005] The present invention also proposes the use of a material feeding device in the preparation of bricks.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A method for improving the accuracy of digital fabric includes the following steps:

[0008] (1) Enlarge the preset pattern proportionally to increase the horizontal and vertical dimensions of the preset pattern;

[0009] (2) Design the fabric path for the nozzle based on the horizontal and vertical dimensions of the enlarged preset pattern;

[0010] (3) Drive the conveying surface to move horizontally; before and / or during the material distribution of the nozzle, adjust the angle of the nozzle on the conveying surface; adjust the nozzle to tilt from one side of the conveying surface in the conveying direction to the other opposite side in the conveying direction, with the tilting direction of the nozzle forming an angle α with the conveying direction of the conveying surface, so that the material is distributed in the transverse direction according to the original transverse dimensions of the preset pattern; at the same time, slow down the conveying speed of the conveying surface so that the material is distributed in the longitudinal direction according to the original longitudinal dimensions of the preset pattern.

[0011] In step (1), the preset pattern is enlarged proportionally and the horizontal and vertical dimensions of the preset pattern are stretched into a parallelogram. The parallel sides of the parallelogram are parallel to the conveying surface in the conveying direction, and the hypotenuse of the parallelogram forms an acute angle with the conveying surface.

[0012] In step (2), in the fabric path of the nozzle, the nozzle first prints at the acute angle formed by one of the hypotenuses of the parallelogram, and finally prints at the acute angle formed by the parallel side and the other hypotenuse of the parallelogram.

[0013] Alternatively, in step (3), the nozzle outputs the powder to the conveying surface.

[0014] In step (1), the preset pattern is enlarged proportionally and the horizontal and vertical dimensions of the preset pattern are stretched into a parallelogram. The parallel sides of the parallelogram are parallel to the conveying surface in the conveying direction, and the hypotenuse of the parallelogram forms an acute angle with the conveying surface.

[0015] In step (2), in the fabric path of the nozzle, the nozzle first prints at the acute angle formed by one of the hypotenuses of the parallelogram, and finally prints at the acute angle formed by the parallel side and the other hypotenuse of the parallelogram.

[0016] Alternatively, in step (3), a conveying device can be used as the conveying surface; the conveying device includes: a receiving drive wheel, a receiving driven wheel, a receiving timing belt, and a receiving motor;

[0017] The receiving synchronous belt connects the receiving drive wheel and the receiving driven wheel to rotate synchronously. The receiving synchronous belt is located below the nozzle. The output end of the receiving motor is connected to the receiving drive wheel to drive the receiving drive wheel to rotate clockwise or counterclockwise, causing a section of the receiving synchronous belt to pass horizontally below the nozzle. The tilt direction of the nozzle forms an angle α with the conveying direction of the receiving synchronous belt.

[0018] Alternatively, in step (3), the conveying surface receives the fabric from the nozzle via a receiving plate.

[0019] A fabric processing device for improving the accuracy of digital fabrics, characterized in that it comprises: a pattern processing module, a conveying device, and a printhead;

[0020] The pattern processing module is used to enlarge the preset pattern proportionally, thereby increasing the horizontal and vertical dimensions of the preset pattern, and to design the fabric path for the nozzle based on the enlarged horizontal and vertical dimensions of the preset pattern.

[0021] The conveying device is equipped with a conveying surface that has a conveying function;

[0022] The nozzle is used to output material to the conveying surface according to the fabric path designed by the pattern processing module; the nozzle is tilted from one side of the conveying surface in the conveying direction to the other opposite side in the conveying direction, and the tilting direction of the nozzle forms an angle α with the conveying direction of the conveying surface.

[0023] When the nozzle distributes material onto the conveying surface of the conveying device, the conveying device receives the material from the nozzle at a reduced speed.

[0024] Optimally, the conveying device includes: a receiving drive wheel, a receiving driven wheel, a receiving timing belt, and a receiving motor;

[0025] The material receiving synchronous belt connects the material receiving drive wheel and the material receiving driven wheel in a synchronous rotation, and the material receiving synchronous belt is located below the nozzle; the output end of the material receiving motor is connected to the material receiving drive wheel, and is used to drive the material receiving drive wheel to rotate clockwise or counterclockwise, so that a section of the material receiving synchronous belt passes horizontally below the nozzle; the tilt direction of the nozzle forms an angle α with the conveying direction of the material receiving synchronous belt.

[0027] Compared with the prior art, one of the above technical solutions has the following beneficial effects:

[0028] This solution provides a method for improving the accuracy of digital fabric application. First, a preset pattern is enlarged. Then, a fabric path is designed based on the enlarged pattern. By adjusting the included angle α and slowing down the conveying speed of the conveying surface, the nozzle applies the original size pattern with a new fabric path, thereby improving the fabric accuracy and resolution. This solves the problem of low accuracy caused by the limitation of the nozzle in existing fabric application methods. Attached Figure Description

[0038] like Figure 1-3 A method for improving the accuracy of digital fabrics includes the following steps:

[0039] (1) Enlarge the preset pattern proportionally to increase the horizontal and vertical dimensions of the preset pattern;

[0040] When enlarging the preset pattern, it is preferable to enlarge it proportionally, such as by 1x, 2x, 3x, etc.; when the preset pattern is enlarged, its image size increases, which is equivalent to enlarging the horizontal and vertical dimensions; at the same time, it is also possible to enlarge the horizontal dimension by one specific factor and the vertical dimension by another specific factor; in this way, after the size is enlarged, the pixel count decreases; for example, it may be high definition at the original size, but may be standard definition after the size is enlarged; some areas of the enlarged image have unclear textures, blurred structures, unclear colors, etc.; for this, step (2) is performed.

[0041] The image processing module 1 refers to the mechanism in electronic devices such as computers, mobile phones, and controllers that has image processing functions;

[0042] (2) Design the fabric path for nozzle 3 based on the horizontal and vertical dimensions of the enlarged preset pattern;

[0043] For magnified preset patterns, areas that are blurry or unclear can be repaired by designing and adjusting the actual cloth path of the nozzle 3. For example, areas with unclear textures or structures can be supplemented to increase the amount of paint sprayed; areas with black patches can be ignored, have the amount of cloth sprayed increased, or have the amount of cloth sprayed decreased; and areas with unclear colors can have colored materials added to improve accuracy.

[0044] (3) Drive the conveying surface 20 to move horizontally; before and / or during the material distribution of the nozzle, adjust the angle of the nozzle 3 on the conveying surface 20; adjust the nozzle 3 to tilt from one side of the conveying surface 20 in the conveying direction to the other opposite side in the conveying direction, and the tilting direction of the nozzle 3 forms an angle α with the conveying direction of the conveying surface 20, so that the material is distributed in the transverse direction according to the original transverse dimension of the preset pattern; at the same time, slow down the conveying speed of the conveying surface 20 so that the material is distributed in the longitudinal direction according to the original longitudinal dimension of the preset pattern.

[0045] The conveying surface 20 is a known mechanism with a driving and moving function, such as the conveyor belt of the conveying device 2, the receiving plate 25 conveyed by the conveyor roller, the pulling plate of the moving trolley, etc. It only requires the conveying surface 20 to move and receive materials. Figure 1 and Figure 2 In the diagram, the horizontal arrow indicates the horizontal movement direction of the conveyor surface 20. Therefore, in this solution, during the material feeding process, the nozzle 3 is designed with the feeding path based on the enlarged preset pattern size. Thus, by default, the pattern printed by the nozzle 3 is the enlarged size. However, this solution also requires that the size after feeding matches the preset pattern size. Therefore, a size adjustment step is performed simultaneously during feeding. Specifically, before or during feeding, the tilt direction of the nozzle 3 forms an angle α with the conveying direction of the conveyor surface 20, and the conveying speed of the conveyor surface 20 is reduced. For the material based on the original lateral dimension of the preset pattern, such as... Figure 2The length of the nozzle 3 in the inclined direction is AC, the length of the fabric in the conveying direction of the conveying surface 20 is AB, BC is the actual horizontal dimension of the print, and the longitudinal and transverse references make AB and BC perpendicular to each other to form a 90° angle. With AC remaining constant, reducing the included angle α reduces the size of BC, thus adjusting the actual lateral dimension of the print. Simultaneously, for the material based on the original longitudinal dimension of the preset pattern, on the one hand, the conveying speed of the conveying surface 20 is slowed down, allowing it to receive more fabric in the same time interval, resulting in a reduction in the actual longitudinal printed size. On the other hand, reducing the included angle α leads to an increase in AB, also increasing the actual longitudinal printed size. The conveying speed only needs to be slowed down to offset the increase in AB caused by the reduction of included angle α. Thus, for a specific magnification ratio of the preset pattern, the included angle α and the slowing speed of the conveying surface can be set accordingly, ensuring that the actual printed size matches the size of the preset pattern. The fabric path of the printhead 3 is designed based on the magnified lateral and longitudinal dimensions of the preset pattern. This improves fabric accuracy and simultaneously compresses the fabric size during fabric application to achieve size initialization, thereby improving printing accuracy and resolution. This solves the problem of low accuracy caused by the limitations of the printhead 3 in existing fabric application methods. Slowing down the conveying speed of the conveying surface 20 refers to reducing the speed of printing the preset pattern to a specific value under natural conditions.

[0046] This solution provides a method for improving the accuracy of digital fabric application. First, a preset pattern is enlarged. Then, a fabric path is designed based on the enlarged pattern. By adjusting the included angle α and slowing down the conveying speed of the conveying surface 20, the nozzle 3 applies the original size pattern with a new fabric path, thereby improving the fabric accuracy and resolution. This solves the problem of low accuracy caused by the limitation of the nozzle 3 in existing fabric application methods.

[0047] Preferably, in step (1), the preset pattern is enlarged proportionally, and the horizontal and vertical dimensions of the preset pattern are stretched into a parallelogram. The parallel sides of the parallelogram are parallel to the conveying surface in the conveying direction, and the hypotenuse of the parallelogram forms an acute angle with the conveying surface.

[0048] In step (2), in the fabric path of the nozzle, the nozzle first prints at the acute angle formed by one of the hypotenuses of the parallelogram, and finally prints at the acute angle formed by the parallel side and the other hypotenuse of the parallelogram.

[0049] like Figure 4After the preset pattern 4 is enlarged proportionally, the horizontal and vertical dimensions are stretched so that the enlarged graphic becomes a parallelogram; the parallel sides of the parallelogram are the vertical dimensions, and the hypotenuses of the parallelogram are the horizontal dimensions; compared with the embodiment of enlarging the preset pattern proportionally, the advantage of enlarging and stretching the preset pattern proportionally is that the horizontal dimension can be at an angle to the conveying surface, thereby making the horizontal dimension larger, and the horizontal dimension does not need to exceed the two sides of the conveying surface, thereby making the enlargement ratio larger; in step (3), the nozzle uses the two hypotenuses of the parallelogram as the starting and ending positions of printing; the hypotenuses The nozzle first prints at one end of one of the hypotenuses, forming an acute angle with the parallel side, then gradually prints the entire hypotenuse. After the entire main body of the preset pattern is printed, the other hypotenuse is printed last, until the acute angle formed by the parallel side and the other hypotenuse is completed. In this way, after the lateral dimension is enlarged, the actual lateral dimension of the material is reduced by the angle α formed by the tilt direction of the nozzle and the conveying direction of the conveying surface. This allows the material to be distributed in the lateral direction according to the original lateral dimension of the preset pattern. After the material is distributed according to the original lateral and longitudinal dimensions, the final distribution range of the material is shown in Figure 5. Ideally, the acute angle formed by the nozzle at one end of the hypotenuse of the parallelogram can be equal to the angle α, thus facilitating the conversion of proportions.

[0050] Alternatively, in step (3), a conveying device 2 is used as the conveying surface 20; the conveying device 2 includes: a receiving drive wheel 21, a receiving driven wheel 22, a receiving timing belt 23, and a receiving motor 24;

[0051] The receiving synchronous belt 23 connects the receiving drive wheel 21 and the receiving driven wheel 22 to rotate synchronously. The receiving synchronous belt 23 is located below the nozzle 3. The output end of the receiving motor 24 is connected to the receiving drive wheel 21 and is used to drive the receiving drive wheel 21 to rotate clockwise or counterclockwise, causing a section of the receiving synchronous belt 23 to pass horizontally below the nozzle 3. The tilt direction of the nozzle 3 and the conveying direction of the receiving synchronous belt 23 form an angle α.

[0052] In this design, a receiving motor 24 drives a receiving drive wheel 21. Under the opening action of the receiving driven wheel 22 and the receiving drive wheel 21 on the receiving synchronous belt 23, the receiving synchronous belt 23, which serves as the conveying surface 20, rotates, causing a section of the receiving synchronous belt 23 to pass horizontally below the nozzle 3. The receiving motor 24 can drive the receiving drive wheel 21 to rotate clockwise or counterclockwise, thus allowing the receiving synchronous belt 23 to move forward and backward. Once the receiving synchronous belt 23 has moved forward, the nozzle 3 will... The powder is output to the receiving synchronous belt 23; then, the receiving motor 24 can drive the receiving drive wheel 21 to rotate counterclockwise. After the receiving synchronous belt 23 is reset, the receiving motor 24 can drive the receiving drive wheel 21 to rotate clockwise again, passing under the nozzle 3 again. When the receiving synchronous belt 23 moves forward, the nozzle 3 outputs the powder to the receiving synchronous belt 23 again. In this way, the receiving synchronous belt 23 moves forward and backward multiple times, which can achieve the effect of quickly applying multiple layers of powder, thereby quickly applying complex textures.

[0053] The nozzle 3 device in this scheme can also arrange the nozzle 3 for spraying glue and the nozzle 3 for spraying powder in a straight line, thus forming front and rear nozzles 3. In use, the conveyor surface 20 can move in a straight line to spread different materials along the way, which can spread materials quickly in large quantities.

[0054] Alternatively, in step (3), the conveying surface 20 receives the fabric from the nozzle 3 via the receiving plate 25.

[0055] When the nozzle 3 is applying the material, it can either apply the material directly onto the conveying surface 20 or receive the material on the receiving plate 25 of the conveying surface 20, so that the powder can be transferred manually or automatically after the material is applied. The receiving plate 25 can be empty, and the powder can be applied directly onto the receiving plate 25 and then transferred, or a blank can be pre-set, and the powder can be applied directly onto the surface of the blank.

[0056] A fabric device for improving the accuracy of digital fabric includes: a pattern processing module 1, a conveying device 2, and a printhead 3;

[0057] The pattern processing module 1 is used to enlarge the preset pattern proportionally, thereby enlarging the horizontal and vertical dimensions of the preset pattern, and to design the fabric path for the nozzle 3 based on the enlarged horizontal and vertical dimensions of the preset pattern.

[0058] The conveying device 2 is provided with a conveying surface 20 that has a conveying function;

[0059] The nozzle 3 is used to output material to the conveying surface 20 according to the fabric path designed by the pattern processing module 1; the nozzle 3 is tilted from one side of the conveying surface 20 in the conveying direction to the other opposite side in the conveying direction, and the tilting direction of the nozzle 3 forms an angle α with the conveying direction of the conveying surface 20.

[0060] When the nozzle 3 distributes material onto the conveying surface 20 of the conveying device 2, the conveying device 2 receives the material from the nozzle 3 at a reduced speed.

[0061] This solution provides a fabric application device for improving the accuracy of digital fabric application. The device first enlarges the preset pattern through the pattern processing module 1, then designs the fabric path based on the enlarged pattern, and then adjusts the included angle α of the nozzle 3 and slows down the conveying speed of the conveying surface 20, so that the nozzle 3 applies the original size pattern with a new fabric path, thereby improving the fabric application accuracy and resolution and solving the problem of low accuracy caused by the limitation of the nozzle 3 in the existing fabric application method.

[0062] Optimally, the conveying device 2 includes: a receiving drive wheel 21, a receiving driven wheel 22, a receiving timing belt 23, and a receiving motor 24;

[0063] The receiving synchronous belt 23 connects the receiving drive wheel 21 and the receiving driven wheel 22 to rotate synchronously. The receiving synchronous belt 23 is located below the nozzle 3. The output end of the receiving motor 24 is connected to the receiving drive wheel 21 and is used to drive the receiving drive wheel 21 to rotate clockwise or counterclockwise, causing a section of the receiving synchronous belt 23 to pass horizontally below the nozzle 3. The tilt direction of the nozzle 3 forms an angle α with the conveying direction of the receiving synchronous belt 23.
