The fully automatic horizontal cotton baler consists of a housing, hydraulic station, hydraulic cylinder, pressure head, and binding mechanism. The hydraulic pressure provided by the hydraulic station drives the main cylinder to compress the material using the pressure head. After compression, the bale is ejected by the ejection hydraulic cylinder, and the binding mechanism binds the bale. The entire bale compression and binding process is controlled by a PLC. The binding mechanism automatically completes the feeding, binding, and tightening processes without manual intervention, resulting in a high degree of automation. This makes it not only highly efficient but also saves labor costs. Therefore, it is widely used in applications requiring large throughput and high processing speed, such as cotton mills, textile mills, and waste treatment plants.
