Description

Technical Field

[0001] The utility model relates to the field of printing medium positioning equipment, in particular to a coated paper positioning mechanism and an industrial printer. Background Art

[0002] Coated paper, also known as printing coated paper, is made by applying a layer of white coating on the surface of the base paper and then undergoing super calendering. It is available in single-sided and double-sided versions, and the paper surface is available in glossy and cloth-textured versions. The paper surface is smooth, white, and has good ink absorption and inking properties. It is mainly used for offset and gravure fine-line printing, such as high-end picture albums, calendars, books, and periodicals. When printing, in order to avoid tilting of the printed image, the coated paper needs to be positioned in advance.

[0003] For example, the utility model with the authorization announcement number CN221339961U discloses a color printing machine that is convenient for feed alignment, including a base and a spraying platform, wherein the spraying platform is fixedly connected to the top of the base, a first motor is fixedly connected to the top of the inner cavity of the base, a first threaded rod is fixedly connected to the bottom end of the power output shaft of the first motor, a first threaded sleeve is screwed to the outer wall of the first threaded rod, a mounting plate is fixedly connected to the bottom end of the first threaded sleeve, universal wheels are rotatably connected to the four corners of the bottom of the mounting plate, and limit rods are fixedly connected to the left and right sides of the top of the mounting plate, and the top ends of the limit rods on the left and right sides are fixedly connected to the base. The color printing machine that is convenient for feed alignment can automatically adjust the position and direction of the cardboard when loading, and can pre-process the wrinkles on the surface of the cardboard to facilitate loading. However, the device adopts physical structure to force alignment, and cannot observe the boundary position of the printing medium in real time, and cannot accurately position when loading paper.

[0017] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0018] Example 1

[0019] This embodiment provides a coated paper positioning mechanism, such as Figure 1 , Figure 2 , Figure 3 As shown, it comprises an upper fixing plate 5 and a printing platform 1 which are arranged opposite to each other. The printing platform 1 is provided with a transverse ruler slit 2 and a vertical ruler slit 3 which are perpendicular to each other.

[0020] The lower surface of the upper fixing plate 5 is provided with a transverse infrared locator 6 and a vertical infrared locator 4. The transverse infrared locator 6 is located directly above the transverse scale slit 2, and the vertical infrared locator 4 is located directly above the vertical scale slit 3. Thus, the transverse infrared locator 6 and the vertical infrared locator 4 can be used to irradiate the printer medium downward as a scale, which is convenient for manual alignment of the printing medium.

[0021] The length of the horizontal ruler slit 2 is greater than the length of the vertical ruler slit 3, and the vertical ruler slit 3 is located at one end of the printing platform 1. The horizontal ruler slit 2 is arranged along the length direction of the printing platform 1, and the vertical ruler slit 3 is arranged along the width direction of the printing platform 1.

[0022] Specifically, the transverse ruler slit 2 and the vertical ruler slit 3 are respectively strip holes opened on the upper surface of the printing platform 1, and both ends of the strip holes are arc transitions.

[0023] Specifically, when paper is loaded, the horizontal infrared locator 6 and the vertical infrared locator 4 are first turned on, and then the horizontal and vertical edges of the paper feeding end of the printing medium are placed on the horizontal scale slit 2 and the vertical scale slit 3 respectively. Then, the infrared light emitted by the horizontal infrared locator 6 and the vertical infrared locator 4 is used as a reference to manually adjust and align the printing medium. This enables the boundary of the printing medium to be accurately positioned when paper is loaded. At the same time, the vertical edge of the coated paper can also be observed in real time using the vertical infrared locator, thereby improving the printing effect.

[0024] Example 2

[0025] The main difference between the coated paper positioning mechanism provided in this embodiment and Embodiment 1 is that, in this embodiment, in order to facilitate adjustment according to the width of the printing medium, an infrared instrument guide rail 7 parallel to the transverse scale seam 2 is provided on the lower surface of the upper fixed plate 5, and the transverse infrared locator 6 is slidably set on the infrared instrument guide rail 7.

[0026] That is, the position of the lateral infrared positioning instrument 6 on the infrared instrument guide rail 7 can be adjusted according to the width of the printer medium to manually move and position one end of the printing medium with different widths.

[0027] Example 3

[0028] This embodiment provides an industrial printer equipped with the coated paper positioning mechanism described in Embodiment 1 or Embodiment 2, such as Figure 4 As shown, it includes a printing bracket, a trolley guide rail 8, a paper guide 9, a printing platform 1, and an upper fixed plate 5. The trolley guide rail 8 is arranged on one side above the printing platform, the upper fixed plate is located directly above the printing platform, and the paper guide is connected to the horizontal side of the printing platform.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
