What's the working process of Integrated Paging&Inkjet Coding Machine?

The core of integrated paging and inkjet coding machine lies in the coordinated operation of two key modules: automatic paging and precise inkjet coding. It first separates stacked materials (such as cards, packaging bags, cartons, documents, etc.) into individual units one by one, then synchronously prints coding content (such as production dates, batch numbers, QR codes, page numbers, etc.) on them. Ultimately, it realizes an automated assembly line operation of "separation - coding - output". Its specific working principle can be broken down into 3 core links, which are closely connected to ensure high efficiency and precision:

I.Core Premise: Material Preprocessing and Loading

Before starting the equipment, basic preparations are required to lay the foundation for the subsequent automated process:

1. Material Arrangement: Stack the materials to be processed (such as stacked cardboards, unsealed packaging bags) neatly on the equipment's feeding table. Ensure the edges of the materials are aligned to prevent paging jams caused by skewed stacking.
2. Parameter Setting: Preset key parameters through the equipment's operation panel, including:

       - Paging speed (adjusted according to material thickness and texture);

       - Inkjet coding content (text, numbers, QR codes, patterns, etc., edited via touch screen or imported via USB);

       - Inkjet codingposition (e.g., top-left corner, middle, boTtom of the material, with coordinates calibrated by sensor encoders);

II.Core Link 1: Automatic Paging 

The paging module is the "front-end core" of the equipment. Its purpose is to convert stacked materials from a "stacked state" to a "continuous single-sheet conveying state" and prevent material overlapping (overlapping will cause inkjet coding misalignment or missing codes). According to material textures (such as paper, plastic, thin metal sheets), mainstream paging methods are divided into two categories:

1. Friction-based Paging (Most Commonly Used)

   - Principle: A "driving friction wheel" (usually with a rubber surface to increase friction) is installed under the feeding table, and a corresponding "pressure wheel" (with adjustable pressure) is set above it. When the stacked materials are pushed to the friction wheel, the friction force generated by the rotation of the friction wheel "rubs" the single sheet at the bottom (or top) layer of the stack, making it separate from the stacked body. At the same time, the pressure wheel presses the remaining stacked materials to prevent multiple sheets from being lifted together.

   - Applicable Scenarios: Paper materials (such as cards, instruction manuals, courier waybills), thin plastic bags, and other materials with a certain degree of surface friction.

2. Baffle-type / Airflow-assisted Paging

   - Principle: For materials with smooth surfaces that are easy to stick together (such as film bags, thin metal sheets), it is difficult to separate them only by friction. Therefore, an additional "baffle" or "airflow nozzle" is added. The baffle forms a "block" at the edge of the stacked materials, allowing only a single sheet to pass through the gap of the baffle. The airflow nozzle sprays a small amount of compressed air between the stacked materials to "blow apart" the materials and assist in single-sheet separation.

   - Applicable Scenarios: PE film bags, aluminum foil bags, thin metal labels, and other materials that are easy to stick together.

Regardless of the method used, the paged materials will be conveyed to the next link - the inkjet coding area - at a stable speed via a conveyor belt. The speed of the conveyor belt is accurately matched with the paging speed and inkjet coding speed (to avoid material jamming or advancing ahead of schedule).

III.Core Link 2: Precise Inkjet Coding 

The inkjet coding module is the "core functional area" of the equipment. It needs to accurately print the preset content on the single-sheet materials after paging, with the key lying in "precise positioning" and "clear printing":

1. Positioning Calibration Before Inkjet Coding

A photoelectric sensor is installed above the conveyor belt. When materials enter the inkjet coding area along with the conveyor belt, the sensor detects the "front edge" or "specific positioning point" (such as a pre-printed mark on the material) of the materials and immediately sends a "trigger signal" to the inkjet coding system - informing the inkjet head that "the material has reached the designated position and inkjet coding can start".

   - Key Point: The sensitivity of the sensor can be adjusted (to avoid missing detection or false triggering), and the position of the inkjet head can be fine-tuned through a mechanical structure (forward/backward, left/right, up/down) to ensure that the printed content falls within the preset coordinate range (e.g., error ≤ ±0.5mm).

2. Inkjet Coding Speed Matching

The printing speed of the inkjet head is synchronized in real-time with the speed of the conveyor belt (coordinated uniformly by the equipment control system). For example, if the conveyor belt speed is 1m/s, the inkjet head needs to complete printing within an extremely short time (e.g., 0.1 seconds) when the material passes through the inkjet coding area. If the speeds are not matched, the printed content will be "stretched" or "compressed" (e.g., characters become flat or thin).

Overall Process Logic

The working principle of the integrated paging and inkjet coding machine is essentially "automated coordination": from "material loading → paging separation (anti-overlapping) → positioning triggering → precise inkjet coding", each link is linked through "sensors + control system". Finally, it replaces the tedious processes of manual paging, manual inkjet coding, and manual quality inspection. Its core advantages are "high efficiency (hundreds to thousands of pieces per minute)", "high precision (small error)", and "strong stability (24-hour continuous operation)". It is widely used in scenarios requiring batch identification, such as food packaging, pharmaceutical labels, electronic components, and document page number marking.
