Description

Technical Field

[0001] This utility model relates to the field of surface printing technology for food packaging paper boxes, and more specifically, to a surface printing device for food packaging paper boxes. Background Technology

[0002] Food packaging plays multiple key roles in the food industry. It not only protects food from contamination and extends its shelf life, but also allows consumers to understand key product information through surface information display. Its exquisite design can enhance product competitiveness and promote sales. The surface printing technology of food packaging can intuitively display brand logos, product features, etc., which is of great significance for shaping brand image and enhancing product recognition.

[0003] A search revealed that Chinese patent application number CN202420098199.5 discloses a surface printing device for food packaging paper boxes, including a machine platform. A hidden box is fixedly installed at the bottom of the machine platform, and an overlapping platform is fixedly installed on one side of the hidden box. A limiting groove is opened in the middle of the top surface of the overlapping platform, and a bearing component is slidably connected to the top surface of the overlapping platform. Conveyor belt components are rotatably connected to both ends of the inner sidewall of the machine platform.

[0004] Although the aforementioned patent uses a pressing component to fix several sets of pressing components by sliding several sets of sliding rings to the appropriate position according to the width of the food packaging box and turning the pressing threaded column, so that the torque spring force acting on the rotating rod causes the pressing plate of the pressing component to press against the packaging box, facilitating digital printing on the surface of the packaging box by the printing press, and ensuring the printing effect of digital printing of small-batch customized packaging boxes by maintaining the same height of the packaging box entering the printing press, the following shortcomings still exist in use: 1. It is difficult to flexibly adjust the printing height according to the thickness of the packaging box, resulting in poor printing contact and poor effect; 2. Adjusting the pressing components of packaging boxes of different widths is cumbersome, inefficient, and difficult to guarantee accuracy.

[0005] Therefore, there is an urgent need for a surface printing device for food packaging boxes to solve the above problems. Utility Model Content

A pressure plate is fixedly connected to the outer wall of the sliding ring. A telescopic rhomboid frame is rotatably connected to the outer wall of the sliding ring. An adjustment frame is rotatably connected to the outer wall of the telescopic rhomboid frame. A uniformly distributed pin hole is opened on the outer wall of the adjustment frame, and the pin hole is slidably connected to the pin rod.

[0014] As a preferred technical solution of this application, a mounting frame is fixedly connected to the outer wall of the hidden box, a drive motor is fixedly connected to the outer wall of the mounting frame, and the output end of the drive motor is fixedly connected to the rotating roller.

It is suitable for printing packaging boxes of various thicknesses and solves the problem in the existing technology that it is difficult to flexibly adjust the printing height according to the thickness of the packaging box, resulting in poor printing contact and poor effect.

[0021] 2. The equidistant synchronous adjustment component enables one-step adjustment in the width direction, eliminating the need to adjust the position of each pressure plate individually. This significantly saves adjustment time and improves production efficiency. At the same time, the equidistant synchronous adjustment ensures uniform pressure from the pressure plates on the packaging box, keeping the packaging box stable during printing and improving printing quality. This solves the problems of cumbersome operation, low efficiency, and difficulty in guaranteeing accuracy when adjusting the pressure components of packaging boxes of different widths in existing technologies.
