After the automatic horizontal baler is started, the material is first fed into the machine's hopper via the accompanying conveyor. The conveyor uses either a belt or chain conveyor, depending on the material type, to deliver the material to be baled at a uniform speed into the machine's hopper. During this process, the control system monitors the hopper's fill level in real time. When the material reaches the preset fill level, the conveyor automatically stops feeding to prevent overloading of the hopper and affect subsequent compression. This ensures a relatively even distribution of the material within the hopper, laying the foundation for the compression process.

After the material is fed, the machine enters the compression molding stage. The core power comes from the hydraulic system. A hydraulic pump generates high-pressure oil, which is delivered via a pipeline to a compression cylinder. This drives a piston rod within the cylinder, driving a ram to apply horizontal pressure to the material within the material bin. The ram slowly advances under the hydraulic pressure, compacting the loose material until it reaches the preset density and volume. During the compression process, the hydraulic system uses a relief valve to stabilize the pressure, preventing damage from excessive pressure or insufficient pressure from causing incomplete compression. This ensures that the final material block meets the required hardness and density.

After the material is compressed and formed, the machine automatically initiates the strapping process. The strapping mechanism wraps strapping (usually plastic or steel) around the compressed material block according to the preset strapping path. The strapping mechanism then tightens, heat-seals, or snaps the strapping securely to the material block, preventing it from loosening during subsequent handling. After strapping is complete, the excess strapping tape is automatically cut off, and the strapping mechanism resets, ready for the next strapping operation. The entire process requires no manual intervention, achieving fully automatic strapping and securing.

After the strapping process is complete, the machine enters the unloading and reset phase. At this point, the bin's discharge door automatically opens, and the compression cylinder drives the ram in reverse, pushing the bundled material blocks out of the bin. The blocks slide along the discharge rails to the designated storage area or conveyor. After unloading, the ram returns to its initial position, the discharge door automatically closes, and the conveyor resumes feeding, allowing the machine to enter the next strapping cycle. Throughout this process, the control system coordinates the timing of each component's actions, ensuring seamless transitions from conveying, compression, strapping, and unloading, enabling continuous, automatic strapping.
