Safety concerns for open mill machines have always been a major worry for rubber and plastic equipment manufacturers, and a significant potential hazard. Many customers purchase open mills due to these concerns, yet due to production requirements, they must still use them. In response to this issue of open mill safety, Lina has developed a new type of open mill that effectively addresses the safety factors associated with these machines.

Open mixers are among the equipment with a high incidence of workplace accidents during rubber processing. Their working environment, compared to other mixing equipment, contributes to a higher risk factor. Operators frequently come into contact with materials and roller cylinders during operation. Most workplace accidents occur when operators are drawn into the roller cylinders by the materials. To ensure the personal safety of engineers and operators, safety training and a highly secure piece of equipment are indispensable.

Traditional open mill machines are typically driven by chains, with a significant issue being that if an accident occurs during operation, the machine shuts down to protect the operator. However, after the power is cut off, the two rollers of the machine continue to rotate due to inertia, or if an emergency braking system is used, it still leaves the operator at risk of continuous injury, making the situation difficult to handle. Accidents on open mill machines can cause minor hand compression injuries, while severe cases can threaten an entire arm or even life.

In response to the human body's natural reflexes, we have installed safety devices on all aspects of the open mill. When an operator's hand is about to be caught in the open mill, our safety device is triggered by the body's spontaneous combustion response. At this moment, the open mill immediately executes two commands: one, it stops immediately without any inertia movement; two, it reverses by a quarter turn. This ensures that even if there is a slight pinch, the fingers are released. The large open mill is designed with a belly-touch switch, adjustable according to the operator's height and arm length, allowing the operator to only touch the roller working surface during operation. If the operator is pulled by the roller, the safety switch is triggered, causing an immediate emergency stop and reversal.

Safety is paramount above all else; ensuring employees work in a safe environment is a fundamental requirement for our basic equipment.
