3. Working Principle and Structural Composition

3.1 Core Working Principle

The Automatic Dessicant Filling Machine takes the PLC control system as the core, and realizes the coordinated operation of each mechanism through the combination of pneumatic, servo drive and sensing detection technology, and completes the whole process of desiccant filling in accordance with the preset program. The basic working process is as follows:

First, the desiccant is stored in the feeding hopper, and the automatic feeding mechanism (vibration feeder, spiral conveyor or pneumatic conveying device) transports the desiccant to the metering unit according to the set flow rate. The metering unit adopts high-precision sensors (infrared counting sensor, weighing sensor, volume metering sensor) to measure the desiccant, ensuring that the single filling amount meets the process requirements. Then, the positioning mechanism fixes the container (insulating glass spacer frame, packaging bottle, etc.) at the designated filling position, and the filling head moves to the filling port under the drive of the servo motor to complete the desiccant filling. For insulating glass special models, after filling, the automatic sealing mechanism uses butyl rubber to seal the drilling hole to prevent desiccant leakage and moisture intrusion; for packaging line models, after filling/inserting, the detection mechanism checks for missing filling, broken bags and other problems, and the unqualified products are automatically rejected, while the qualified products enter the next process. In addition, the machine is equipped with a material level sensor, which triggers an alarm and starts the automatic replenishment function when the desiccant is insufficient, ensuring the continuity of production.

The whole process is controlled by the PLC system, and the operating parameters (filling amount, filling speed, filling height, sealing time, etc.) can be adjusted and set through the touch screen, and the production data (production quantity, qualified rate, fault information, etc.) can be recorded and displayed in real time to realize intelligent management of the production process.

Hot Melt Coating Machine: Professional Technical Description & Comprehensive Overview

1. Introduction to Hot Melt Coating Machine

The Hot Melt Coating Machine is a highly integrated, precision-engineered industrial processing equipment dedicated to the application of hot melt adhesives onto a wide variety of flexible and semi-rigid substrates. As a core piece of equipment in the adhesive coating and composite material industry, it replaces traditional solvent-based and water-based coating methods with a solvent-free, pollution-free, and highly efficient thermal bonding process. It integrates mechanical transmission, precision temperature control, automatic metering, continuous coating, cooling setting, tension control and intelligent electrical control systems, realizing stable, high-speed and high-quality roll-to-roll coating production. It is widely recognized as an indispensable and advanced production solution in modern manufacturing, meeting the strict requirements of product performance, environmental protection standards and production efficiency in multiple industries.

2. Working Principle and Operational Mechanism

The operating principle of the hot melt coating machine is based on the physical phase change of hot melt adhesive and precise fluid coating technology, forming a complete and stable closed-loop production system. The entire production process can be divided into several key steps: adhesive melting, quantitative delivery, precision coating, cooling curing and finished product winding.

First, solid hot melt adhesive particles, blocks or strips are added to the special heating melting tank of the equipment. Under the precise multi-zone temperature control system, the solid adhesive is heated and converted into a uniform liquid state with stable viscosity. Then, the high-precision gear pump or screw metering pump system transports the molten adhesive at a constant pressure and fixed flow rate to the coating head module, eliminating the influence of adhesive viscosity and liquid level changes on the coating effect.

Next, under the synchronous operation of the substrate transmission system, the molten adhesive is uniformly coated on the surface of the substrate through the coating head in the form of a full film, dots, lines or mesh according to the process requirements. Immediately after coating, the substrate with the adhesive layer enters the cooling and shaping zone, where the adhesive is rapidly cooled and solidified through cooling rollers or circulating air cooling to restore a solid state and form a firm adhesive layer.

Throughout the process, the PLC central control system monitors and adjusts key parameters in real time, including heating temperature, metering pump speed, substrate transmission speed, tension value and coating thickness, ensuring the consistency and stability of the coating effect and achieving fully automated continuous operation.

The cooling system adopts high-efficiency cooling rollers with internal circulating cooling water or strong air cooling equipment, which can quickly reduce the surface temperature of the coated substrate, accelerate the curing and forming of the hot melt adhesive, prevent the adhesive from flowing or transferring, and ensure the flatness and stability of the coating layer.

3.6 Tension Control and Transmission System

The whole line adopts a segmented tension control system to keep the tension of the substrate stable during unwinding, coating and winding. The servo-driven variable-frequency transmission system realizes high-precision speed synchronization, supports high-speed continuous production, and runs smoothly with low noise.
