Description

Technical Field

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

[0002] Printing equipment on the surface of packaging cartons is an indispensable part of the carton manufacturing industry. Its function is to print the required text, patterns and other information onto the surface of the cartons. Packaging carton printing equipment is widely used in food packaging, daily necessities packaging, electronic product packaging and other fields. With the rapid development of e-commerce and logistics industries, the demand for packaging cartons is constantly increasing, which also puts forward higher requirements for the performance and efficiency of printing equipment.

[0003] Existing printing devices for packaging cartons lack post-printing quality inspection structures. For example, a rapid printing mechanism for packaging cartons disclosed in application number CN201921819568.0 relies mainly on manual visual inspection for traditional printing quality inspection. This method is not only inefficient but also susceptible to human factors, leading to missed inspections or misjudgments. Existing printing devices typically lack real-time monitoring capabilities, making it impossible to monitor and provide feedback on printing quality in real time during production. This means that once a problem occurs, it may not be discovered until the entire batch of production is completed, thereby increasing production costs and waste. This not only affects the overall quality of the product but may also reduce production efficiency and increase the company's operating costs.

[0004] Therefore, it is necessary to invent a printing device for the surface of packaging cartons to solve the above problems. Utility Model Content

[0026] The working principle of this practical application is as follows:

[0027] Refer to the instruction manual appendix Figure 1-5For this type of printing device used on the surface of packaging cartons, the cartons are first conveyed by the conveyor frame 2. Limiting strips 201 on both sides of the conveyor frame ensure that the cartons do not deviate from the track during conveying, while anti-slip strips 202 between the limiting strips prevent the cartons from sliding during conveying. The first motor 401 at the rear end of the fixed platform 4 drives the top frame 5 to move back and forth via the first telescopic rod 402 to adjust the printing position. Simultaneously, the bottom surface of the top frame 5 slides in the groove 403 on the surface of the fixed platform 4 via a slider 404, ensuring accurate and stable lateral printing position. The first... The second motor 501 drives the upper plate of the roller brush 6 to adjust its vertical position through the second telescopic rod 502 and the auxiliary telescopic rod 503. The mounting plate 601 and the roller brush wheel 602 on the bottom of the upper plate of the roller brush 6 are responsible for evenly brushing the surface of the carton. The inspection camera 704 in the inspection frame 7 moves back and forth in the moving groove 701 through the reciprocating screw 702 and the moving seat 703 to perform quality inspection on the printed carton to ensure that the quality of the printed pattern and text meets the requirements. The fan 8 on the outer wall of the inspection frame 7 can blow away the heat and ink odor generated during the printing process, while keeping the equipment clean and the working environment comfortable.

[0028] When using this device, first ensure that the equipment is in good working condition, check whether the power supply and air pressure are normal, and lubricate all components. Send the prepared cartons into the conveyor 2, adjust the carton conveying speed to match the printing press speed, and adjust the parameters of the first motor 401 and the second motor 501 according to the carton specifications and printing requirements to ensure the accuracy of printing position and printing pressure. Press the start button, and the printing press starts working. The cartons are conveyed through the conveyor 2, and after printing on the roller brush plate 6, the quality is inspected by the inspection camera 704 in the inspection frame 7. After printing is completed, collect the finished cartons on the conveyor belt for subsequent processing and packaging. This printing device for the surface of packaging cartons is efficient, accurate, and reliable, and can meet the requirements of the carton manufacturing industry for printing quality and production efficiency.
