For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] The screen is an important part of screen printing equipment. The tension of the screen on the screen has a great influence on the effect of screen printing. If the screen is too loose, the screen will leave too much ink on the printed workpiece during printing, affecting the printing effect; if the tension of the screen frame on the screen is too large, it is easy to cause the screen to break and cannot be used.

[0029] See also Figures 1 to 3The utility model provides a screen for screen printing, comprising a first screen frame 1, a second screen frame 2, a screen 3 and an edge banding strip 4; the first screen frame 1 is sleeved on the outer side of the second screen frame 2, and a gap is formed between the inner side wall of the first screen frame 1 and the outer side wall of the second screen frame 2, the screen 3 covers the second screen frame 2, and the edges of the screen 3 extend between the first screen frame 1 and the second screen frame 2, a plurality of edge banding strips 4 are provided, and the plurality of edge banding strips 4 are respectively provided on the edges of the screen 3, the first screen frame 1 presses the edge banding strips 4 and the edges of the screen 3 on the outer side wall of the second screen frame 2, so that the screen 3 and the edge banding strips 4 are respectively fixed between the first screen frame 1 and the second screen frame 2, and the screen 3 located above the second screen frame 2 is in a tensioned state.

[0030] In the above, the screen 3 and the edge banding strip 4 of appropriate sizes are set according to the sizes of the first screen frame 1 and the second screen frame 2, so that when the first screen frame 1 is mounted on the second screen frame 2, the screen 3 can be quickly fixed and tensioned through the cooperation of the first screen frame 1, the second screen frame 2 and the edge banding strip 4, which simplifies the screen stretching process for screen printing and reduces the dependence of the screen stretching process for screen printing on the technical proficiency of the operator.

[0031] The first screen frame 1 and the second screen frame 2 are made of light, strong and low-cost materials, which not only ensure the strength of the screen, but also control the equipment cost. For example, the first screen frame 1 and the second screen frame 2 are made of one of an aluminum alloy frame, a plastic frame, etc.

[0032] In the present embodiment, the first mesh frame 1 and the second mesh frame 2 are respectively configured as rectangular frames, the four corners of the rectangular frames are configured as rounded corners, the wire mesh 3 is configured as a rectangular structure matching the first mesh frame 1 and the second mesh frame 2, and the arc surface 42 formed by the corresponding angles on the first mesh frame 1 and the second mesh frame 2 is coaxial, ensuring that the first mesh frame 1 can be balancedly mounted on the second mesh frame 2. After the first mesh frame 1 is mounted on the second mesh frame 2, the center of gravity of the first mesh frame 1 and the second mesh frame 2 coincide, so that the distances between the four sides of the first mesh frame 1 and the four sides of the second mesh frame 2 are equal, ensuring that the edge banding strips 4 located on each outer side of the second mesh frame 2 are subjected to the same pressure from the first mesh frame 1, thereby improving the uniformity of the tensioning force on the wire mesh 3 and ensuring the tensioning effect of the wire mesh 3.

[0033] The four corners of the first screen frame 1 and the four corners of the second screen frame 2 are rounded to prevent the corners of the first screen frame 1 or the second screen frame 2 from scratching the screen 3, thereby changing the aperture of the screen 3 and affecting the screen printing effect.

[0034] When installing the above-mentioned screen, first place the second screen frame 2 horizontally, and then cover the screen 3 on the second screen frame 2, so that the edge strip 4 is located on the side facing the second screen frame 2, and the edge strips 4 at the outer edges of the screen 3 in all directions are located on the outside of the second screen frame 2, and then the first screen frame 1 is sleeved from the top of the screen 3 to the second screen frame 2, and the first screen frame 1 drives the edges of the screen 3 to bend to form a gap between the first screen frame 1 and the second screen frame 2 during the downward pressing process, so that the edge strips 4 located at the edges of the screen 3 are driven to between the first screen frame 1 and the second screen frame 2, and as the first screen frame 1 is pressed downward, the screen 3 is gradually tensioned until the screen 3 and the edge strips 4 are pressed against the outer wall of the second screen frame 2 by the inner wall of the first screen frame 1, so that the screen 3 is quickly fixed. At this time, the upper surface of the screen 3 is just tensioned into a printing surface with a suitable tension.

[0035] like Figure 2 , Figure 4 and Figure 5 As shown, the screen 3 includes a fixed portion 31 and a printing portion 32, and the fixed portion 31 and the printing portion 32 are an integrally formed mesh structure. The fixed portion 31 is distributed around the printing portion 32, and the fixed portion 31 is arranged between the first screen frame 1 and the second screen frame 2. The edge strip 4 is arranged on the fixed portion 31, extending from the connection between the fixed portion 31 and the printing portion 32 to the edge of the fixed portion 31, and is located on the side of the fixed portion 31 facing away from the first screen frame 1. The printing portion 32 is arranged above the second screen frame 2, and the lower surface of the printing portion 32 close to the fixed portion 31 contacts the upper surface of the edge strip 4, so that the edge strip 4 can generate a certain tensioning force on the screen 3 at the intersection of the fixed portion 31 and the printing portion 32, thereby ensuring the tensioning effect of the printing portion 32.

[0036] The printing part 32 of the screen 3 is used to form the pattern or text to be printed. During screen printing, by adding ink to the printing part 32 and applying a certain pressure to the printing part 32, the ink passes through the mesh on the printing part 32 and falls on the substrate, so that the image or text formed on the printing part 32 is transferred to the substrate. The substrate can be selected from materials such as paper, wood, glass, metal, plastic, etc. The aperture and wire diameter of the screen 3 can be set according to the requirements of the printed workpiece, and are not limited here.

[0037] like Figure 4 and Figure 5As shown, the edge banding strip 4 forms a 90-degree corner 41 at the connection between the fixing portion 31 and the printing portion 32, one of the two planes forming the corner 41 is parallel to the printing portion 32 and contacts each other, and the other of the two planes forming the corner 41 is perpendicular to the printing portion 32, so that the fixing portion 31 can be pressed tightly against the inner wall of the first mesh frame 1, so that the screen 3 is not easily displaced after being fixed, and the contact area between the edge banding strip 4 and the screen 3 and between the screen 3 and the first mesh frame 1 is increased, the connection stability between the screen 3 and the first mesh frame 1 is improved, and the tensioning effect of the edge banding strip 4 on the screen 3 is improved.

[0038] like Figure 5 As shown, the upper surface of the edge banding strip 4 is flush with the upper surface of the second screen frame 2, ensuring the flatness of the surface of the screen 3 located above the second screen frame 2, thereby ensuring the effect of screen printing.

[0039] The upper surface of the first mesh frame 1 is not lower than the upper surface of the edge strip 4 , so that the fixing portion 31 of the wire mesh 3 connected to the edge strip 4 can be pressed by the inner wall of the first mesh frame 1 to ensure the tensioning effect of the wire mesh 3 .

[0040] Preferably, the upper surface of the first screen frame 1 is flush with the upper surface of the edge banding strip 4, so that the upper surface of the first screen frame 1 does not exceed the upper surface of the screen 3, thereby avoiding that the screen 3 cannot be in horizontal contact with the substrate due to the first screen frame 1 during printing, thereby affecting the screen printing effect.

[0041] like Figure 4 and Figure 5 As shown, the upper part of the edge strip 4 near the second screen frame 2 is provided with a curved surface 42. When the screen is installed and fixed, the first screen frame 1 presses against the edge strip 4, and the curved surface 42 on the edge strip 4 will rotate upward relative to the outer wall of the second screen frame 2. The setting of the curved surface 42 facilitates the rotation of the edge strip 4, so that the edge strip 4 can move smoothly during the flipping process, thereby ensuring that the screen 3 can be gradually tightened smoothly.

[0042] The width of the connection between the edge banding strip 4 and the wire mesh 3 is greater than the length of the gap between the first mesh frame 1 and the second mesh frame 2, ensuring that the first mesh frame 1 can press on the edge banding strip 4 when pressing against the wire mesh 3 covering the second mesh frame 2, so that the edge banding strip 4 rotates as the first mesh frame 1 moves downward, thereby fixing the edges of the edge banding strip 4 and the wire mesh 3 between the inner wall of the first mesh frame 1 and the outer wall of the second mesh frame 2.

[0043] In order to ensure the strength of the edge banding 4 and control the cost of the product, the edge banding 4 is made of a material that is light in weight, has a certain strength and is low in cost. For example, the edge banding 4 can be made of an aluminum alloy or a plastic part.

[0044] In one embodiment, the edge banding strip 4 is adhered to the edge of the wire mesh 3 by an adhesive, and the connection is stable and can maintain the flatness of the surface of the wire mesh 3, thereby avoiding the introduction of connecting parts to affect the flatness of the contact surface between the wire mesh 3 and the first mesh frame 1, thereby affecting the tensioning effect of the wire mesh 3.

[0045] In this embodiment, the screen 3 is configured as a rectangular shape adapted to the second screen frame 2, including a first side edge and a second side edge, a third side edge and a fourth side edge that are opposite to each other, the first side edge intersects with one end of the third side edge and one end of the fourth side edge respectively, and the second side edge intersects with the other end of the third side edge and the other end of the fourth side edge respectively, and an edge band 4 is provided on each side edge of the screen 3, the extension direction of the edge band 4 is consistent with the length direction of the side edge corresponding to the screen 3, and the two ends of the edge band 4 extend to the position close to the intersection of the side edge and the adjacent two side edges, so as to improve the uniformity of the tension of the edge band 4 on each position of the screen 3. Exemplarily, one end of the edge band 4 on the first side edge extends to the intersection close to the first side edge and the third side edge, and the other end extends to the intersection close to the first side edge and the fourth side edge; one end of the edge band 4 on the third side edge extends to the intersection close to the first side edge and the third side edge, and the other end extends to the intersection close to the third side edge and the second side edge.

[0046] A plurality of edge banding strips 4 may be arranged on each side edge of the wire mesh 3, and the plurality of edge banding strips 4 are arranged in sequence along the length direction of the corresponding side edge of the wire mesh 3, and a certain gap may be provided between adjacent edge banding strips 4, or the edge banding strips 4 may be connected end to end. The edge banding structure formed by the plurality of edge banding strips 4 extends to the position where the corresponding side edge of the wire mesh 3 intersects with the adjacent two side edges.

[0047] It is worth noting that the “upper” direction referred to in this application refers to the orientation of the surface of the screen 3 that bears ink during printing; that is, the surface of the screen 3 that bears ink is the upper surface of the screen 3, and the surface of the edge strip 4 that faces the upper surface of the screen 3 is the upper surface of the edge strip 4.

[0048] In summary, the utility model arranges a first screen frame and a second screen frame which are nested with each other, and arranges edge strips on the four edges of the screen. The inner wall of the first screen frame can press the edge of the edge of the screen and the screen tightly against the outer wall of the second screen frame, so as to realize rapid fixation and tensioning of the screen. The utility model has a simple structure, simplifies the screen stretching process for screen printing, and reduces the dependence of screen stretching on the technical proficiency of the operator.

[0049] In addition, during the fixing process of the wire mesh, the position of the edge banding strip rotating relative to the outer wall of the second mesh frame is set to an arc surface, so that the edge banding strip can rotate stably relative to the second mesh frame during the fixing process of the wire mesh, thereby improving the smoothness of the wire mesh fixing process and thus improving the tensioning effect of the wire mesh.

[0050] The edge banding strip is arranged at a position where the screen faces away from the outside of the first screen frame, and the upper surface of the edge banding strip is flush with the upper surface of the second screen frame, thereby ensuring the flatness of the screen printing surface and enabling the screen to be supported not only by the upper surface of the second screen frame but also by the tensioning effect of the edge banding strip.

[0051] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the claims attached to the utility model.
