Introduction to 6-inch open mill

The 6-inch open mill is one of the small experimental open mills with high precision, wear resistance, low noise and high safety performance. The small experimental open mill produced by Lena is a cooperative supplier designated by universities and scientific research institutes. Customers who have successfully signed contracts include Tsinghua University, South China University of Technology, Chinese Academy of Sciences and many other well-known universities.

Working principle of 6-inch open mill

When the 6-inch open mill is in operation, the two rollers rotate relative to each other, similar to the internal mixer, using different speed ratios to shear and pressure the material, thereby breaking the molecular chain. During the mixing process, manual addition of additives, also known as additives, is required. In addition, the open mill requires manual flipping of the glue, which inevitably results in high physical consumption of personnel, poor safety performance, poor site environment, and dust flying. This is also a common problem among all open mills in the industry.

Advantages of the Lina Open Refiner

The practice in the industry is to have emergency stop switches on both sides, but in fact, they are just for decoration. Imagine waiting until we realize that our hands are almost being rolled into the roller of the open mill, will we still have time to press that switch? It's definitely too late. So this is the biggest difference between us and other companies, which is that we pay great attention to safety when designing the open mill. Think about it, if a device has serious security risks, even if the price is cheap, if something happens, it won't be worth the loss.

At the beginning, the Lina Kai mixer used infrared sensing, but later it was found that it was not feasible because the temperature of the rubber material was constantly changing, which could easily lead to misjudgment. Later, it was adopted to install circuits and switches at the knee position. When danger appeared, as long as the knee was pushed forward, the mixer immediately performed two actions: one was to stop immediately, and then immediately reverse. This is our patent. Now perhaps our peers can imitate our functions, but they cannot imitate the essence. The essence is whether the roller stops immediately and then reverses immediately? Just like driving, it's difficult to brake the car immediately. It takes a few seconds to brake, and that's the key to the problem.

Structural characteristics of Lina 6 open mill

1. The overall base plate is easy to install, and the transmission mode is single axis output to ensure high torque. Imported bearings reduce rubbing force to ensure power saving, low noise, and even and controllable rubber thickness;

2. The core technology and main components come from Taiwan, with high precision and low noise. Most of the accessories are imported from Fortune 500 companies;

3. The machine is equipped with emergency brakes. In the event of an emergency, there are emergency switches at all four corners, which facilitate multi position braking and quick stopping of the machine;

4. The roller is made of vanadium titanium alloy cold hard cast iron, with a hard and wear-resistant surface that is durable Precision machining of the inner cavity of the roller ensures rapid and uniform cooling of the roller body;

5. The transmission device adopts a hard tooth surface reducer, which has a compact structure, high transmission efficiency, and low noise;

6. The machine adopts manual distance adjustment, precise thickness control, and easy operation;

7. The safety performance of the Lina 6-inch open mill is much safer than that of ordinary open mills.
