[0043] like Figure 1-3 and Fig. 9 As shown, an automatic line drawing machine for curtain fabrics is used for drawing lines on fabrics, comprising:

[0044] The table assembly 5 includes a conveyor belt 51, a first motor 52, a first rotating shaft 53 and a second rotating shaft 54. The first rotating shaft 53 and the second rotating shaft 54 ​​are arranged on both sides of the inside of the conveyor belt 51. The first motor 52 is used to drive the first rotating shaft 53 to rotate. The conveyor belt 51 is used to place cloth to drive the cloth to move.

[0045] A housing 1, wherein a bracket 7 is disposed inside the housing 1, and the housing 1 is located above the conveyor belt 51;

[0046] The brush device 3 is arranged on the bracket 7, and includes a brush 31, a translation component and a lifting component. The lifting component is fixed on the translation component. The brush 31 is fixed on the lifting component and is located above the conveyor belt 51 to drive the brush 31 to move up, down, left and right.

[0047] The pressing plate 4 is disposed on the bracket 7 to press the cloth when the brush 31 draws lines on the cloth.

[0048] The utility model places cloth on a table assembly and drives the cloth to move through a first motor. After the cloth moves to a target distance, the cloth is fixed by pressing downwards through a pressure plate, and then the brush is driven downwards onto the cloth by a lifting assembly, and the brush is driven left and right by a translation assembly to complete automatic line drawing on the cloth, thereby improving production efficiency. Moreover, due to the arrangement of the pressure plate and the line drawing device, the line drawing accuracy can be improved, thereby reducing the defective rate of products.

[0049] like Figure 4 As shown, the lifting assembly includes a lifting motor 32 and a first connecting member 33 , the lifting motor 32 is fixed on the first connecting member 33 , the first connecting member 33 is fixed on the translation assembly, and the driving end of the lifting motor 32 is fixedly connected to the paintbrush 3 .

[0050] like Figure 6 As shown, the translation assembly includes a second motor 35 and a belt 34 , the second motor 35 is used to drive the belt 34 to rotate, and the first connecting member 33 is fixed on the belt 34 .

[0051] like Figure 1 As shown, the automatic curtain fabric marking machine also includes a laser locator 2 , which is fixed on the housing 1 .

[0052] By using the laser locator 2, the alignment of the fabric can be detected before the brush device 3 draws the line, further reducing the defective rate of the fabric.

[0053] like Figure 6-7 As shown, the automatic line marking machine for curtain fabrics also includes a distance measuring component 6, which includes an encoder 61, a third motor 62 and a second connecting member 63. The third motor 62 is used to drive the encoder 61 to rotate, and the third motor 62 is fixedly connected to the second connecting member 63. The second connecting member 63 is fixedly arranged on the bracket 7.

[0054] It is worth noting that although the moving distance of the cloth from the last line-drawing position to the current position can be obtained by the number of rotations of the first motor 52, and whether the position where the line needs to be drawn is determined by the moving distance, the calculation of this moving distance needs to be obtained by the first motor 52, and there may be errors. By setting up the distance measuring component 6, the moving distance of the cloth can be directly obtained, which is more accurate and further reduces the stability of the product.

[0055] like Figure 8 As shown, the distance measuring assembly further includes a torsion spring 64, a first limiting column 65 and a second limiting column 66, wherein the first limiting column 65 is closer to the encoder 61 than the second limiting column 66, and in terms of vertical height, the first limiting column 65 is lower than the second limiting column 66;

[0056] The torsion spring 64 is rotatably mounted on the second connecting member 63 , the first limiting column 65 and the second limiting column 66 are fixedly mounted on the second connecting member 63 , one end of the torsion spring 64 is located between the first limiting column 65 and the second limiting column 66 , and the other end is located below the first limiting column 65 .

[0057] This embodiment can reduce the friction between the encoder and the cloth by providing the torsion spring 64, the first limiting post 65 and the second limiting post 66, and prevent the encoder 61 from always being in close contact with the cloth, thereby preventing the quality of the cloth from being affected by the friction of the encoder 61.

[0058] Preferably, the cloth bags are located below both ends of the conveyor belt 51 along the moving direction.

[0059] like Figure 2 and Fig. 9 As shown, the conveyor belt 51 is provided with a plurality of micro holes 511;

[0060] Sealing structures are provided at both ends of the conveyor belt, and the sealing structures are provided with air outlets 55 .

[0061] In this embodiment, the automatic curtain fabric marking machine can be connected to an external suction device through the air outlet 55, thereby generating wind pressure in the micropores 511, so that the fabric is closely attached to the conveyor belt, which can ensure the accuracy of fabric movement and further reduce the production defect rate.

[0062] In one embodiment, in order to improve the uniformity of the force applied to the fabric on the conveyor belt 51, Figure 2 As shown, the micro holes 511 are distributed on the conveyor belt 51 in an array.

[0063] Based on the same inventive concept, an embodiment of the present application further provides a line drawing system, including an air suction device and the automatic line drawing machine for curtain fabrics as described above, wherein the air inlet of the air suction device is connected to the air outlet 55 .

[0064] Since the marking system includes the above-mentioned curtain fabric automatic marking machine, it can reduce the production defect rate and improve production efficiency. In addition, it uses the suction device to suck air from the micro holes on the conveyor belt to generate wind pressure, so that the fabric is closely attached to the conveyor belt, ensuring the accuracy of fabric movement and further reducing the production defect rate.

[0065] It should be noted that the terms "horizontal", "vertical" and the like do not mean that the components are absolutely horizontal or vertical, but can be slightly tilted; the terms "parallel", "vertical" and the like do not mean that the components are absolutely parallel or vertical, but can form a certain angle deviation. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted. In addition, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the product of the present application is usually placed when used, which is only for the convenience of describing the embodiments of the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0066] It is to be understood that the meaning of "plurality" herein is at least two, such as two, three, etc., unless there is a special limitation. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices. The term "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " herein generally indicates that the associated objects before and after are in an "or" relationship.

[0067] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
