[0023] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.
[0024] See also Figure 1 to Figure 2 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.
[0025] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.
[0026] See also Figure 1 The utility model provides a screen printing plate for printing the outer surface of a car, comprising a screen printing frame 2 and a screen printing screen 1. The screen printing screen 1 is installed in the screen printing frame 2 in a tensioned manner. The screen printing frame 2 is elastic. When it is necessary to spray text and patterns on the outer surface of the car, the screen printing frame 2 is bent to fit the shape of the outer surface of the car, so that the screen printing screen 1 is attached to the outer surface of the car, ensuring that the ink used for spraying can be clearly and completely printed on the outer surface of the car through the screen printing screen 1, thereby improving the spraying quality. The one-time printing pass rate of the printing device where the screen printing plate is located is improved, and the waste of ink is avoided, thereby solving the problems of low pass rate and high cost in the prior art.
[0027] like Figure 1As shown, a positioning device and a spirit level are installed on the silk-screen frame 2; the spirit level displays the level of the silk-screen frame 2, and the silk-screen frame 2 is fixed on the car through the positioning device. The operator can accurately grasp the level of the silk-screen frame 2 by observing the spirit level, so as to make appropriate adjustments to the silk-screen frame 2. After the position of the silk-screen frame 2 is properly adjusted, the silk-screen frame 2 is fixed to the car through the positioning device, thereby ensuring the accuracy of the spraying position of the text and pattern on the outer surface of the car, and the positioning method is accurate and fast, which solves the problem of inefficiency of the spraying method in the prior art and further improves the one-time pass rate of the spraying of the outer surface of the car.
[0028] In another embodiment, see Figure 1 The screen printing frame 2 is provided with a bubble groove, and the level is a level bubble 3 installed in the bubble groove. The level bubble 3 is easy to observe and has low cost. In addition to the method in this embodiment, the designer can also use an electronic level. The operator can more intuitively grasp the horizontality of the screen printing frame 2 through the numbers on the electronic level. However, the cost of the electronic level is higher than that of the bubble, and the relevant designer specifically selects the structural form of the level according to the needs.
[0029] In another embodiment, see Figure 1 and Figure 2 A handle 5 is installed on the screen printing frame 2 to facilitate the operator to adjust the position of the screen printing frame 2.
[0030] In another embodiment, see Figure 1 The silk-screen frame 2 is a quadrilateral, and the quadrilateral silk-screen frame 2 has the widest application scenarios and the best interchangeability; the level bubble 3 is installed on the upper edge of the silk-screen frame 2. Compared with being installed on the left edge, the right edge and the lower edge, the level bubble 3 is installed on the upper edge for easier observation by operators; the handle 5 is installed on the left edge and the right edge of the silk-screen frame 2, which makes it easier for operators to adjust the levelness of the silk-screen frame 2.
[0031] In another embodiment, see Figure 1 , the material of the screen printing frame 2 is aluminum alloy. Wooden frames and steel frames are also commonly used in the prior art. Among them, although the wooden frame is very low in cost and easy to handle, the strength of the wooden frame is low, and it is greatly affected by temperature and humidity. It is not suitable for printed products with high requirements and high overprinting accuracy, and its lifespan is relatively short. Although the steel frame has good firmness, it is relatively heavy and easy to rust. It needs to be properly treated, such as galvanizing or painting, and the cost is relatively high. The aluminum frame has a small specific gravity and is relatively light. Even a large screen frame is easy to handle, and the cost is lower than that of the steel frame. The cross-section selection range is wide, it is rust-resistant, easy to clean, and easier to bend. Comprehensively comparing the advantages and disadvantages of the three materials, it is most appropriate to choose aluminum alloy material to make the screen printing frame 2.
[0032] In another embodiment, see Figure 1 and Figure 2 The positioning device includes a positioning rod 4 and a hook. One end of the positioning rod 4 is fixedly connected to the screen printing frame 2 by bolts to facilitate disassembly and maintenance; the other end of the positioning rod 4 is hung on the car through the hook to provide positioning and fixing functions.
[0033] In another embodiment, see Figure 1 and Figure 2 The hook is clamped on the door handle of the car. The hook is elastic because the most common place to spray text and patterns on cars, especially trucks, is the door. For example, according to national standards, the door panels on both sides of the truck cab must be sprayed with total mass parameters; so designing the hook to be able to clamp the door handle is a specific design method suitable for cars that spray text or patterns on the door. Designers can also flexibly design the structure of the hook according to the changes in the spraying position.
[0034] In other embodiments, Figure 1 As shown, the screen printing screen 1 includes a nylon screen and a soft film, and the soft film and the nylon screen are bonded together and pasted together in the screen printing frame 2, wherein the printing ink cannot penetrate the soft film, and the place on the screen printing screen 1 where the pattern is printed is not bonded with the soft film, thereby ensuring that the text pattern printed by the screen printing plate is clear and not blurred.
[0035] See also Figure 1 The utility model provides a printing device, including a scraper, ink and a screen printing plate for printing the outer surface of a car as described above. The printing device has the advantages of thick sprayed ink layer, strong covering power, no restriction on the shape of the outer surface of the car, small printing pressing force, economy and environmental protection, simple and accurate positioning method and high one-time printing pass rate through the design of the scraper, ink and the screen printing plate as described above. Compared with the printing methods of the outer surface of the car such as hollow molds, instant sticky molds and automatic spraying systems in the prior art, the printing device has the advantages of thick sprayed ink layer, strong covering power, no restriction on the shape of the outer surface of the car, small printing pressing force, economy and environmental protection, simple and accurate positioning method and high one-time printing pass rate. These advantages are both inherent in the screen printing method itself and achieved through the screen printing plate designed in the utility model, such as quick and accurate positioning and spraying without restriction on the shape of the outer surface of the car.
[0036] In other embodiments, the printing device further includes a printing table for driving the scraper to move. Compared with manually operating the scraper, using the printing table to operate the scraper has higher spraying efficiency and is easier to ensure spraying quality.
[0037] In summary, the utility model has a screen printing frame 2 with an elastic design, so that the screen printing frame 2 can be bent according to the shape of different car surfaces, ensuring that the screen printing screen 1 can be attached to the outer surface of the car, thereby ensuring that the ink is clearly and completely printed on the outer surface of the car through the screen printing screen 1; at the same time, through the design of the positioning device and the level, the screen printing screen 1 can be accurately fixed at a suitable position on the outer surface of the car, thereby ensuring the position accuracy of the text pattern printed on the outer surface of the car; the printing device is then designed through the scraper, ink and the screen printing plate designed by the utility model. Compared with the printing methods of the outer surface of the car such as the hollow font, instant sticker font and automatic inkjet system in the prior art, the device has the advantages of thick ink layer sprayed, strong coverage, not limited by the shape of the outer surface of the car, small printing embossing force, economic and environmental protection, simple and accurate positioning method and high one-time printing pass rate. Therefore, the utility model effectively overcomes the shortcomings of the prior art and has a high industrial utilization value.
