The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0045] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0046] The present application will be described in detail below through examples.

[0047] In existing technologies, there is a demand for printing wide-format images. Wide-format printing typically involves spreading the printing material on a printing platform, and then using an inkjet printer, such as a printhead, to move across the platform to complete the printing process. However, when wide-format printing material is spread out on the printing platform, the excessive width often causes the edges of the material to curl up, affecting printing accuracy. In severe cases, it can even affect the movement of the printhead, making the print unusable.

[0048] To address the technical problems existing in current printing equipment, the present invention provides a pressure plate for a printer, comprising: a connecting plate, including a vertical portion and a connecting portion, wherein the vertical portion includes a first end and a second end, the first end being detachably fixedly connected to the printer body, and the second end being connected to the connecting portion; and a pressure plate, including an extension portion and a pressing portion, wherein the extension portion is connected to the connecting portion, and the pressing portion abuts against printing material disposed on the printing platform, wherein the extension portion of the pressure plate forms a first angle with the vertical portion of the connecting plate, and the first angle is an obtuse angle.

[0049] According to this invention, by setting the connection between the pressure plate extension and the vertical part of the connecting plate to an obtuse angle, the pressure plate can be fixed behind the printer body. The pressure plate pressing part continuously applies pressure to the edge of the printing material, avoiding edge curling and other issues when printing wide-format images, thereby improving printing efficiency and printing quality.

[0050] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0051] Based on the inventive concept of this application, in some preferred embodiments of this application, a pressure plate 1 for a printer is provided, as shown in the reference. Figures 1-2 ,include:

[0052] The connecting plate 11 includes a vertical portion 111 and a connecting portion 112. The vertical portion 111 includes a first end 1111 and a second end 1112. The first end 1111 is detachably fixedly connected to the printer body 2, and the second end 1112 is connected to the connecting portion 112. The pressure plate 12 includes an extension portion 121 and a pressing portion 122. The extension portion 121 is connected to the connecting portion 112, and the pressing portion 122 abuts against the printing material disposed on the printing platform. The extension portion 121 of the pressure plate forms a first angle with the vertical portion 111 of the connecting plate, and the first angle is an obtuse angle.

[0053] By adopting the above technical solution, the connection between the pressure plate extension 121 and the vertical part 111 of the connecting plate is set to an obtuse angle, which allows the pressure plate 1 to be fixed on the printer body 2. After the pressure plate clamping part 122 applies pressure to the edge of the printing material, it avoids the occurrence of edge warping and other issues when printing wide-format images, thereby improving printing efficiency and printing quality.

[0054] In some embodiments, the vertical part 111 and the connecting part 112 are integrally formed, which facilitates production and can improve the connection efficiency and stability of the connecting plate 11 and the pressure plate 12.

[0055] In some preferred embodiments, reference Figures 1-2The first end portion 1111 includes a first magnetic attraction portion 11111 arranged vertically, which can be magnetically attracted to the corresponding position of the printer body 2 and thus fixed.

[0056] In a specific implementation, the first magnetic suction part 11111 may include a plurality of magnets spaced apart, and the magnets may be fixed to the first end 1111 by screws or bolts.

[0057] In some preferred embodiments, the first end portion 111 further includes a second magnetic attraction portion 11112 arranged at right angle to the vertical direction. The second magnetic attraction portion 11112 can be magnetically attracted to the corresponding position of the printer body and thus be fixed.

[0058] In specific implementation, the second magnetic attraction part 11112 may include a plurality of spaced magnets, which can be fixed to the first end 1111 by screws or bolts. In some preferred embodiments, the vertical part 111 further includes a support plate 113, which supports the second magnetic attraction part 11112 and provides vertical support for the second magnetic attraction part 11112.

[0059] Using the above technical solution, the pressure plate 1 is detachably fixed to the printer body 2 by the first magnetic suction part 11111 and the second magnetic suction part 11112, which is convenient for installation and saves costs.

[0060] In some preferred embodiments, reference Figures 1-2 The support plate 113 includes a first plate 1131 and a second plate 1132 arranged vertically. The first plate 1131 is connected to the vertical part 111, and the second plate 1132 is connected to the vertical part 111. By adopting the above technical solution, the second magnetic part 11112 can be more stably connected to the vertical part 111.

[0061] Specifically, refer to Figure 2 The support plate 113 is closer to the second end 1112 than the first magnetic attraction part 11111, so that the second magnetic attraction part 11112 is positioned upwards and lower than the first magnetic attraction part 11111. This design reduces the load on the support plate 113 and improves the stability and durability of the product. In some embodiments, a rib 13 is connected between the first plate 1131 and the second plate 1132, and the position of the rib 13 corresponds to the second magnetic attraction part 11112 to provide better support.

[0062] In some preferred embodiments, the distance between the second magnetic suction part 11112 and the second end 1112 is smaller than that between the first end 1111, so as to ensure the stability of the center of gravity of the pressure plate 1 when it is working.

[0063] In some preferred embodiments, the second magnetic part 11112 is connected to the first magnetic part 11111.

[0064] In some preferred embodiments, reference Figures 1-3 The connecting portion 112 includes a support plate 1121, which forms a first angle α with the vertical portion. The first angle α is preferably 100-120°, more preferably 102°. By adopting the above technical solution, the pressure plate can maintain a large pressure on the printing material after deformation during pressing, and can continue to prevent fatigue of the pressure plate material for a longer period.

[0065] In some preferred embodiments, the extension 121 is connected to the support plate 1121. In practice, the extension 121 is fixed to the support plate 1121 by screws inserted into the first counterweight 14. Because a large deformation pressure is generated at the extension 121 when the pressure plate 12 is bent, the first counterweight 14 is located on the upper surface of the extension 121 to increase the stability of the connection between the extension 121 and the support plate 1121.

[0066] In some preferred embodiments, a second counterweight 15 is provided at the end of the pressing part 122 to prevent the pressure at the end of the pressing part 122 from decreasing.

[0067] In some preferred embodiments, the pressure plate is made of carbon fiber or spring steel.

[0068] In some preferred embodiments, the first counterweight 14 and the second counterweight 15 are made of carbon steel.

[0069] The applicant discovered that when the aspect ratio of the pressure plate exceeds a certain limit, the increase in pressure on the printing material is significantly reduced. Therefore, in some preferred embodiments, the extension 121 of the pressure plate 1 is integrally formed with the connecting part 112, and the aspect ratio of the pressure plate is 8:1-12:1.

[0070] In some preferred embodiments, the pressure plate has a width of 70-90 mm and a thickness of 0.5-2 mm.

[0071] Based on the inventive concept of this application, in some other preferred embodiments of this application, a printer is provided, with reference to... Figure 5 ,include:

[0072] The printer body 2 includes a main beam 21, a printing platform 22, and a nozzle 23. The printing platform 22 is used to place printing material, and the nozzle 23 is installed on the main beam 21 and prints the printing material located on the printing platform 22 under signal control.

[0073] As described in the above embodiment, the vertical part 111 of the connecting plate 11 is detachably fixed to the main beam 21, and the pressing part 122 of the pressure plate 12 abuts against the edge of the printing material located on the printing platform 22 and applies pressure to the printing material so that it is flatter on the printing platform.

[0074] In some preferred embodiments, reference Figure 4 The contact point between the clamping part 122 and the printing platform 22 is the clamping position 4. The intersection of the extension line of the vertical part 111 and the printing platform is the first positioning point 5. There is a first distance between the clamping position 4 and the first positioning point 5. The second end of the vertical part 111 is at a second distance from the printing platform. The ratio of the second distance to the first distance is 3:1 to 6:1. Meanwhile, the distance between the end of the connecting part and the printing material is 2-3 mm.

[0075] By adopting the above technical solution and selecting the first angle α, the pressure plate 12 can maintain a large pressure on the printing material after bending, while slowing down the fatigue rate of the material of the pressure plate 12, thus giving the pressure plate 1 a longer service life. More preferably, the ratio of the second distance to the first distance is 4.70:1.

[0076] In some preferred embodiments, the distance between the end of the connecting portion 112 and the printing platform is 4-4.5 mm. In some preferred embodiments, the length of the connecting portion 112 is 5-20 mm.

[0077] It should be noted that, for those skilled in the art, the technical features in the above embodiments can be freely combined, and the resulting technical solutions also belong to the embodiments disclosed in this application.

[0078] Furthermore, without departing from the principles of this application, several improvements and modifications may be made to this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
