Description

Technical Field

[0001] The utility model belongs to the technical field of inkjet printers, and in particular relates to a feeding component of a UV inkjet printer. Background Art

[0002] UV inkjet printer is a device that combines UV curing ink and digital printing technology, and is widely used in color printing of various materials. Figure 1 As shown, the feeding assembly of most inkjet printers includes a flattening roller and a power roller. The printing fabric passes between the two rollers and enters the bottom of the inkjet assembly. Before inkjet printing, only the two rollers are used to pull the printing fabric. Due to the high flexibility of the printing fabric, wrinkles may appear on the printing fabric before inkjet printing, resulting in poor inkjet printing effect. Summary of the Invention

[0003] The utility model aims to provide a UV inkjet printer feeding assembly, which adds a pressure roller on the basis of existing technology to ensure the flatness of the printed cloth and improve the inkjet printing effect.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A UV inkjet printer feeding assembly includes a mounting plate, a support platform, a power roller and a flattening roller. The mounting plate is arranged on both sides of the support platform, the power roller and the flattening roller are arranged on the mounting plate, and the flattening roller is located above the power roller. A pressure roller is arranged on the mounting plate, and the pressure roller is located above the support platform and at the front end of the conveying direction of the power roller. The printed fabric passes between the power roller and the flattening roller and is conveyed to the bottom of the pressure roller, where the pressure roller and the support platform work together to flatten the printed fabric.

[0006] Furthermore, both ends of the pressure roller are connected with telescopic components, and the telescopic components are telescopically adjusted to adjust the distance between the pressure roller and the support platform.

[0007] Furthermore, the telescopic assembly includes an electric rod, a bearing seat and a bracket; the telescopic end of the electric rod is connected to the bearing seat, the bearing seat is installed at both ends of the pressure roller, the fixed end of the electric rod is installed on the bracket, and the bracket is installed on the side of the mounting plate.

[0008] Furthermore, a U-shaped limiting bracket is installed on the side of the mounting plate, and the electric rod passes through the U-shaped limiting bracket.

[0009] Furthermore, the bracket shown is L-shaped or triangular.

[0010] The utility model has the following beneficial effects:

[0011] (1) By installing a pressure roller between the feed assembly and the inkjet assembly of the existing inkjet printer, the printing cloth is flattened under the joint action of the pressure roller and the support table, thereby ensuring that the printing cloth is in a flat state when it is located under the inkjet assembly, thereby improving the printing effect.

[0012] (2) By connecting a telescopic assembly to the pressure roller and controlling the telescopic assembly to adjust the distance between the pressure roller and the support platform, it is possible to flatten printing fabrics of all thicknesses, thereby improving the adaptability of the inkjet printer. In addition, the length of the pressure roller can be set according to the size of the specific inkjet printer to meet the requirements of different printing fabric widths.

[0013] (3) A limit bracket is provided for the electric rod (telescopic rod) of the telescopic assembly to ensure the stability of the electric rod (telescopic rod) during the telescopic process and the supporting process, and to ensure the flattening effect of the pressure roller.

[0018] The present embodiment provides a UV inkjet printer feed assembly, which adds a pressure roller 4 to the existing feed assembly. The pressure roller 4 is located on the rear side of the feed assembly, that is, between the feed assembly and the inkjet assembly. By arranging a pressure roller 4 between the feed assembly and the inkjet assembly, the fabric to be printed is further flattened to avoid wrinkles, improve the printing effect, and increase the print yield.

[0019] like Figure 2 As shown, the feed assembly includes mounting plates 1 mounted on either side of the inkjet printer. Flattening rollers 2 and powered rollers 3 are both mounted on mounting plates 1, with flattening rollers 2 positioned above powered rollers 3. Powered rollers 3 drive the printed material forward, while flattening rollers 2 initially flatten the material. In this embodiment, a pressure roller 4 is positioned in front of powered rollers 3. This pressure roller 4, along with the printer's support platform, further flattens the printed material, effectively preventing wrinkles.

[0020] like Figure 3As shown, in this embodiment, the pressure roller 4 is installed on the inner side of the mounting plate 1 through a telescopic component. The height of the pressure rod is adjusted by the telescopic component to adapt to printing fabrics of various thicknesses.

[0021] The telescopic assembly includes an electric rod 5, an L-shaped bracket 6 and a bearing seat 8. The bearing seat 8 is installed at both ends of the pressure roller 4 and is connected to the telescopic end of the electric rod 5. The L-shaped bracket 6 is installed on the inner side of the mounting plate 1. The fixed end of the electric rod 5 is installed on the L-shaped bracket 6. By controlling the extension and retraction of the electric rod 5, the pressure roller 4 is driven to rise and fall, so that it can meet the requirements of printing fabrics of all thicknesses.

[0022] This embodiment also provides a limiting structure for the electric rod 5, which includes a U-shaped limiting bracket 7 installed on the side of the mounting plate 1. The electric rod 5 passes through the U-shaped limiting bracket 7 to ensure the stability of the electric rod 5 during and after lifting.

[0023] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any modification and replacement based on the technical solution and utility model concept provided by the present invention should be included in the protection scope of the present invention.
