Description

Technical Field

[0001] The utility model relates to the technical field of fabric printing, in particular to a printing screen for realizing different printing thicknesses. Background Art

[0002] The existing fabrics usually have various pattern designs to increase the beauty of the fabrics. Most of the pattern designs on the fabrics are printed by a printing screen. The existing printing equipment spreads the fabric flat on the tabletop, then aligns the printing window on the printing screen with the position on the fabric where printing is required, then pours the coating, applies a certain pressure to the coating on the printing screen with a squeegee, and moves uniformly from one end of the printing screen to the other end. By moving the squeegee, the pigment is printed on the fabric through the screen to form a pattern. Since the thickness of the existing printing screen is the same, the height of the pattern printed by this printing screen is also the same, and it is impossible to present a 3D stereoscopic printing effect with different heights.

[0003] The existing 3D printing usually first performs planar printing, and then prints again at the concave and convex parts of the printing. Leave a thicker coating at the raised positions; it needs to frequently replace the printing screen, the operation is more inconvenient, and it is time-consuming and laborious, affecting the printing speed. Summary of the Utility Model

[0004] Therefore, it is necessary to provide a printing screen for realizing different printing thicknesses to solve the problem that the existing printing screen cannot present a 3D stereoscopic printing effect with different heights.

[0005] To achieve the above object, the utility model provides a printing screen for realizing different printing thicknesses. The printing screen has a printing window, and at least one part of the side wall of the printing window is lower or higher than other parts, so that the side wall of the printing window has a convex shape or a concave shape in the height direction.

[0006] Further, the printing window includes an upper window part and a lower window part. At least one part of the side wall of the upper window part is lower or higher than other parts, so that the side wall of the upper window part has a convex shape or a concave shape in the height direction.

[0007] Further, at least a pair of the convex shape or the concave shape are respectively arranged at corresponding positions on a pair of side walls of the upper window part.

[0008] Further, the projection of the upper window part in the height direction is located within the lower window part.

[0009] Further, the central axis of the upper window part coincides with the central axis of the lower window part.

[0010] Further, the cross-section of the upper part of the window in the horizontal direction is in a geometric shape or a natural shape, and the cross-section of the lower part of the window in the horizontal direction is in a geometric shape or a natural shape.

[0011] Further, the cross-sectional shapes of the upper part of the window and the lower part of the window in the horizontal direction are the same.

[0012] Further, at least one side wall of the printing window is inclined towards the upper part of the window.

[0013] Different from the prior art, the above technical solution makes the side wall heights of the printing window different by setting the side wall heights of the printing window, so that the side walls of the printing window have a convex shape or a concave shape; when using this printing screen for printing, align the printing window on the printing screen with the position on the base fabric that needs to be printed, pour the coating on the printing screen, and the squeegee closely adheres to the upper end surface of the printing screen (that is, when passing through the printing window, scrape along the side wall height of the printing window), apply a certain pressure to the coating on the printing screen, and move from one side wall of the printing window towards the corresponding other side wall, so that the inside of the printing window is filled with the coating, so that the shape of the upper end surface of the coating is determined according to the side wall height of the printing window, thereby printing out pattern designs with different heights and presenting a 3D stereoscopic printing effect with different heights.

[0031] See Figures 1 - 3 As shown, the present utility model provides a printing screen 10 for achieving different printing thicknesses. The printing screen 10 has a printing window 20. By setting the height of the side wall 201 of the printing window, the height of the side wall 201 of the printing window is made different, so that the side wall 201 of the printing window has a convex shape 205 or a concave shape 204. When using the printing screen 10 for printing, align the printing window 20 on the printing screen 10 with the position on the base fabric that needs to be printed. Pour the coating on the printing screen 10, and the squeegee closely adheres to the upper end surface of the printing screen 10 (that is, when passing through the printing window 20, it scrapes along the height of the side wall 201 of the printing window), apply a certain pressure to the coating on the printing screen 10, and move from one side wall of the printing window 20 to the corresponding other side wall, so that the inside of the printing window 20 is filled with the coating, so that the shape of the upper end surface of the coating is determined by the height of the side wall 201 of the printing window, thereby printing out pattern designs with different heights and presenting a 3D stereoscopic printing effect with different heights.

[0032] See Figure 1 As shown, the following elaborates in detail on a printing screen 10 of the present utility model for achieving different printing thicknesses, specifically as follows:

[0033] The printing screen stencil 10 has a printing window 20, and at least one part of the side wall 201 of the printing window has a height lower than or higher than other parts, so that the side wall 201 of the printing window has a convex shape 205 or a concave shape 204 in the height direction.

[0034] The above-mentioned printing window 20 can be one or more. Multiple printing windows 20 can be arranged irregularly, or can be arranged at intervals with a certain distance to form a regular arrangement, or some printing windows 20 can be closely arranged to convey specific information (such as a printing window 20 in the shape of characters). When there are multiple printing windows 20, the shapes of the multiple printing windows 20 can be exactly the same, completely different, or partially the same, etc. The shape of the printing window 20 here can refer to the shape of the printing window 20 in a certain horizontal section, or the shape of the printing window 20 in a certain height-direction section, or the combination of the shape of the printing window 20 in a certain horizontal section and the shape of the printing window 20 in a certain height-direction section.

[0035] The side wall 201 of the above-mentioned printing window can be interpreted as any one side wall of the side wall 201 of the printing window, or two or more side walls; at least one part of the side wall 201 of the above-mentioned printing window has a height lower than or higher than other parts, so that the side wall 201 of the printing window has a convex shape 205 or a concave shape 204 in the height direction means that: in some embodiments, at least one part of the side wall 201 of the above-mentioned printing window has a height lower than other parts, so that the side wall 201 of the printing window has a concave shape 204 in the height direction. During printing, a pattern with a concave shape 204 is printed corresponding to the concave shape 204 of the side wall 201 of the printing window; in some embodiments, at least one part of the side wall 201 of the above-mentioned printing window has a height higher than other parts, so that the side wall 201 of the printing window has a convex shape 205 in the height direction. During printing, a pattern with a convex shape 205 is printed corresponding to the convex shape 205 of the side wall 201 of the printing window; in some embodiments, at least one part of the side wall 201 of the above-mentioned printing window has a height lower than other parts, and there is also at least one part of the side wall 201 with a height higher than other parts, so that the side wall 201 of the printing window has both a concave shape 204 and a convex shape 205 in the height direction. During printing, a pattern with a convex shape 205 and a convex shape 205 is printed corresponding to the convex shape 205 and the concave shape 204 of the side wall 201 of the printing window.

[0036] The cross-sections of the above-mentioned concave shape 204 and convex shape 205 in the height direction can be in the shape of an arc such as a U shape or an arch shape, or can be a V shape, or formed by a regular or irregular broken line composed of multiple line segments, etc.

[0037] See Figure 2As shown, a further embodiment of the present utility model, the printing window 20 may include an upper window part 203 and a lower window part 202. At least one part of the side wall 2031 of the upper window part has a height lower than or higher than other parts, so that the side wall 2031 of the upper window part has a convex shape 205 or a concave shape 204 in the height direction.

[0038] Similarly, the side wall 2031 of the upper window part described above can be interpreted as any one side wall of the side wall 2031 of the upper window part, or two or more side walls; at least one part of the side wall 2031 of the upper window part has a height lower than or higher than other parts, so that the side wall 2031 of the upper window part has a convex shape 205 or a concave shape 204 in the height direction means that: in some embodiments, at least one part of the side wall 2031 of the upper window part has a height lower than other parts, so that the side wall 2031 of the upper window part has a concave shape 204 in the height direction. During printing, a pattern with a concave shape 204 is printed corresponding to the concave shape 204 of the side wall 2031 of the upper window part; in some embodiments, at least one part of the side wall 2031 of the upper window part has a height higher than other parts, so that the side wall 2031 of the upper window part has a convex shape 205 in the height direction. During printing, a pattern with a convex shape 205 is printed corresponding to the convex shape 205 of the side wall 2031 of the upper window part; in some embodiments, at least one part of the side wall 2031 of the upper window part has a height lower than other parts, and there is also at least one part with a height higher than other parts, so that the side wall 2031 of the upper window part has both a concave shape 204 and a convex shape 205 in the height direction. During printing, patterns with a convex shape 205 and a convex shape 205 are printed corresponding to the convex shape 205 and the concave shape 204 of the side wall 2031 of the upper window part.

[0039] The side wall 2031 of the upper window part has a convex shape 205 or a concave shape 204 in the height direction, which can be one or multiple. When there are multiple, there is no limit to the depth of the concave shape 204 and the height of the convex shape 205. They can be the same in depth of the concave shape 204 and the full height of the convex shape 205, completely different, or partially the same. There is also no limit to the position where the convex shape 205 or the concave shape 204 is set. Of course, it can be set at the corresponding positions of a pair of side walls of the upper window part 203. That is, the convex shape 205 or the concave shape 204 is at least a pair, and is respectively set at the corresponding positions of a pair of side walls of the upper window part 203. During printing, according to the convex shape 205 and the concave shape 204 at the corresponding positions of a pair of side walls of the upper window part 203, a pattern with continuous convex shapes 205 and convex shapes 205 is printed between a pair of side walls of the upper window part 203.

[0040] After the coating forms a pattern, the printing screen 10 needs to be removed. To keep the pattern intact, the space at the lower part 202 of the window needs to be larger than the inner diameter of the upper part, that is, the projection of the upper part 203 of the window in the height direction is located within the lower part 202 of the window. The projection of the upper part 203 of the window in the height direction being located within the lower part 202 of the window means that the projection of the upper part 203 of the window in the height direction can be within the lower part 202 of the window; or the projection of the upper part 203 of the window in the height direction can coincide with or partially coincide with the inside of the lower part 202 of the window. In some embodiments, the central axis of the upper part 203 of the window and the central axis of the lower part 202 of the window can coincide. The coincidence of the central axes can create a symmetrical effect, making the overall shape of the printed pattern more balanced and harmonious.

[0041] The cross-section of the upper part 203 of the above window in the horizontal direction can be in geometric shapes, natural shapes, text shapes, and other free forms. Similarly, the cross-section of the lower part 202 of the window in the horizontal direction can be in geometric shapes, natural shapes, text shapes, and other free forms. The geometric shapes can be regular or irregular polygons such as squares, rhombuses, pentagrams, trapezoids, etc., and can also be circles, ellipses, and other similar shapes. The natural shapes can be shapes such as flowers, leaves, animals, etc.; the text shapes can be letters, numbers, punctuation marks, etc. The free forms can be abstract lines, graffiti, hand-painting, etc. These shapes are not restricted and can create unique printing effects through free expression techniques.

[0042] See Figure 2 and Figure 3 As shown, for further improvement of the above embodiments, at least one side wall of the printing window 20 is inclined inward. The inward inclination of the side wall of the printing window can reduce the friction and resistance between the printed pattern and the inner wall of the window, making it easier for the printing screen 10 to slide out from the printed pattern, so that the process of removing the printing screen 10 is smoother and more convenient, reducing the risk of damage to the printed pattern and improving production efficiency. Specifically, the side wall 2031 of the upper part of the window and the side wall 2021 of the lower part of the window can be continuously inclined, or the side wall 2021 of the lower part of the window can be inclined towards the upper part 203 of the window. Preferably, the side wall 2031 of the upper part of the window and the side wall 2021 of the lower part of the window have smooth surfaces. The smooth surfaces can reduce the resistance and friction of the side walls, making the process of removing the printing screen 10 smoother and more convenient. At the same time, it also reduces the accumulation of dust and dirt during the use of the printing window 20, facilitating cleaning and maintenance.

[0043] It should be noted that although the above embodiments have been described in this text, it does not limit the patent protection scope of the present utility model. Therefore, based on the innovative concept of the present utility model, any changes and modifications made to the embodiments described in this text, or equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, and directly or indirectly applying the above technical solutions to other related technical fields are all included in the patent protection scope of the present utility model.
