[0030] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0031] As described in the background technology, the silk screen in the traditional silk screen printing screen needs to be newly molded according to different silk screen patterns and characters, which requires tens of thousands of dollars in mold opening fees, which is costly. In addition, when switching to different silk screen patterns, the screen needs to be reinstalled, which reduces efficiency and requires re-testing of the first sample to verify the silk screen effect of the new screen, which increases the silk screen printing process and affects the silk screen printing efficiency.

[0032] In order to solve this technical problem, the utility model provides a silk screen printing screen, which is applied to the silk screen printing screen field.

[0033] Specifically, please refer to Figure 1-7 The silk screen screen specifically includes a silk screen 1 and a fixed frame 2, wherein the silk screen 1 is fixedly connected to the fixed frame 2, and further includes a shield 4, wherein the shield 4 is detachably connected to the fixed frame 2 and a hollow silk screen area 5 is provided on the shield 4, and a silk screen pattern 3 is provided on the silk screen 1, and the hollow silk screen area 5 matches the silk screen pattern 3.

[0034] The silk screen printing screen provided by the utility model has a shield plate 4 installed on a fixed frame 2. During silk screen printing, ink passes through the hollowed-out silk screen area 5, passes through the silk screen pattern 3 on the silk screen 1, and silk screens a part of the silk screen pattern 3 on the silk screen object. The silk screen 1 only needs to be opened once, which reduces the mold opening cost. When silk screen printing different patterns, it is only necessary to replace different shield plates 4, and the cost of the shield plates 4 is very low, which greatly reduces the production cost. When switching the silk screen pattern 3, it is only necessary to replace the shield plate 4, and the shield plate 4 is easy to replace. In addition, the same silk screen 1 is used, and there is no need to re-test the silk screen effect, which saves time and improves the silk screen printing efficiency.

[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0036] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0038] Example 1

[0039] Please refer to Figure 1-7 , a screen printing plate is provided, which includes a screen 1 and a fixed frame 2, the screen 1 is fixedly connected to the fixed frame 2 on all sides, the screen 1 is provided with a screen printing pattern 3 of a crown symmetrical in the shape of an "8" character and a crown symmetrical in the shape of an upper and a lower symmetry, a shield 4 is detachably connected to the fixed frame 2, the shield 4 has a size consistent with the screen 1, and the shield 4 is fully fitted and covered on the screen 1, a plurality of shields 4 are provided, and a hollow screen printing area 5 of different fields of the character "8" is opened on each shield 4, and the hollow screen printing area 5 matches the screen printing pattern 3 The hollowed-out silk-screen area 5 includes ten characters from 0 to 9 and a combination with an upper crown or a lower crown. In this example, the character "3" and the lower crown, the character "2" and the upper crown are taken as examples. After the baffle 4 is fixed to the fixed frame 2, the baffle 4 can block other silk-screen patterns 3 on the silk-screen 1, thereby obtaining different silk-screen patterns 3 according to the hollowed-out silk-screen area 5 on the baffle 4, so that different silk-screen patterns 3 of the silk-screen object can be compatible with the same screen plate, thereby achieving silk-screen effects of different characters and patterns.

[0040] The traditional silk screen 1 adopts a polyester mesh plate, which does not have good stability. Under the great pressure of the scraper, the elongation is also relatively large, and there are some deformations that make the ink penetrate unevenly, resulting in the corresponding poor silk screen ink. For this reason, in this example, the silk screen 1 adopts a full steel silk screen 1, which has the characteristics of good plane stability and stable screen pattern size. Even under a large pulling force, the elongation is very small. After the mask 4 is placed, the contact surface of the silk screen 1 and the mask 4 is more flush and tight, so that the silk screen 1 and the mask 4 can be close to each other. During the silk screen printing process when the scraper is pressed down, it can avoid the ink from penetrating from the edge of the hollowed-out silk screen area 5 of the hollowed-out part of the mask 4 to the part that does not need silk screen printing, causing the edge of the characters or patterns to be jagged or the ink overflow.

[0041] Regarding the material of the shield plate 4, in this example, the shield plate 4 is an acrylic plate with a thickness of 1 mm, low cost, and convenient grooving, which reduces the mold opening cost of the silk screen screen by thousands or even tens of thousands, greatly saving production costs.

[0042] The silk screen printing screen provided by the utility model has a shield plate 4 installed on a fixed frame 2. During silk screen printing, ink passes through the hollowed-out silk screen area 5, passes through the silk screen pattern 3 on the silk screen 1, and silk screens a part of the silk screen pattern 3 on the silk screen object. The silk screen 1 only needs to be opened once, which reduces the mold opening cost. When silk screen printing different patterns, it is only necessary to replace different shield plates 4, and the cost of the shield plates 4 is very low, which greatly reduces the production cost. When switching the silk screen pattern 3, it is only necessary to replace the shield plate 4, and the shield plate 4 is easy to replace. In addition, the same silk screen 1 is used, and there is no need to re-test the silk screen effect, which saves time and improves the silk screen printing efficiency.

[0043] Example 2

[0044] The screen printing screen provided in Example 1 is further optimized, specifically, as follows: Figure 2-6 As shown, positioning protrusions 6 are provided on both sides of the baffle 4, and positioning grooves 7 matching the positioning protrusions 6 are provided on the fixed frame 2. The positioning protrusions 6 are provided in two and are symmetrically distributed on both sides of the baffle 4. In this example, the positioning protrusions 6 are triangular in shape, and the positioning protrusions 6 are used to position and engage the baffle 4, so as to facilitate the fixing of the baffle 4. At the same time, anti-reverse protrusions 8 are also provided on the baffle 4, and anti-reverse grooves 9 are provided on the fixed frame 2. The anti-reverse protrusions 8 and the anti-reverse grooves 9 are both rectangular and are not provided on the same side of the baffle 4 as the positioning protrusions 6, so as to avoid the baffle 4 from being reversed and play an anti-foolproof role.

[0045] Through the above-mentioned structural design, a positioning protrusion 6 and an anti-reverse protrusion 8 are set on the baffle 4. When the baffle 4 is placed on the fixed frame 2, a complete locking effect is achieved, so that the hollowed-out silk-screen area 5 is consistent with the silk-screen pattern 3 to prevent deviation. The setting of the anti-reverse protrusion 8 can also prevent the front and back sides of the baffle 4 from being reversed.

[0046] Example 3

[0047] The screen printing screen provided in Example 2 is further optimized, specifically, as follows: Figure 2-4 As shown, a magnet 10 is embedded in the positioning groove 7, and the magnet 10 is a permanent magnet. A magnetic attraction piece 11 is provided on the positioning protrusion 6, so that the positioning protrusion 6 is magnetically fixed to the fixing frame 2, and the magnetic attraction piece 11 is an iron sheet attached to the surface of the positioning protrusion 6, and the iron sheet is provided with an integral boss 12, which passes through the positioning protrusion 6 and extends 5-10mm from the upper surface of the positioning protrusion 6. The size of the iron sheet is consistent with the size of the positioning protrusion 6, and a hole for the boss 12 to pass through is provided on the positioning protrusion 6. After the shield plate 4 is processed, the boss 12 on the iron sheet passes through the hole, and the iron sheet and the positioning protrusion 6 are fixed by glue. Of course, the iron sheet and the shield plate 4 can also be prepared as a whole. After the iron sheet and the positioning protrusion 6 are fixed, the outer surface of the iron sheet is flush with the surface of the corresponding side of the shield plate 4.

[0048] Through the above-mentioned structural design, a magnetic attraction part 11 is arranged on the positioning protrusion 6 and a magnet 10 is embedded in the positioning groove 7, and the baffle 4 is magnetically fixed by magnetic attraction. The baffle 4 can be quickly installed, and the magnetic part is an iron sheet and a protruding column 12 extending out of the positioning protrusion 6 is fixed on the iron sheet, thereby improving the stability of the magnetic fixation and facilitating the removal of the baffle 4.

[0049] The method for using the silk screen screen provided by the utility model is as follows: Taking the silk screen glass cover plate as an example:

[0050] 1. Surface treatment: The glass surface is cleaned and treated to remove oil and other impurities to ensure that the ink can adhere firmly to the glass surface;

[0051] 2. Plate making: Make a silk screen 1 according to the design requirements, transfer the design pattern to the silk screen 1 to form a silk screen pattern 3, and make grooves on the mask 4 to form a hollow silk screen area 5 with different characters and patterns;

[0052] 3. Applying ink: Apply the ink on the mask 4, and use a scraper to evenly press the ink from the hollowed-out screen printing area 5 into the screen printing pattern 3 of the screen 1;

[0053] 4. Printing: Place the screen printing plate on the glass surface and scrape it with a scraper or scraper to transfer the ink from the screen printing pattern 3 on the screen 1 to the glass surface to form a pattern;

[0054] 5. Curing: The ink is cured on the glass surface by drying or UV curing equipment to ensure the durability and stability of the printed pattern.

[0055] The principle is as follows: the process of screen printing ink onto glass is to utilize screen printing technology, the mask 4 partially blocks the screen pattern 3 on the screen 1, and enters the screen pattern 3 part of the screen 1 through the hollowed-out screen printing area 5, and the ink is transferred to the glass surface through the screen pattern 3 part of the screen 1. The ink is transferred to the glass surface through the screen pattern 3 part of the screen 1 by pressure to form the desired pattern. The curing process can enable the ink to form a solid coating on the glass surface to ensure the quality and durability of the pattern.
