Description

Technical Field

[0001] The invention belongs to the technical field of coal sample preparation, and in particular relates to a fine rocker arm double roller machine. Background Art

[0002] The double-roll crusher is a crushing device that crushes coal by rotating the crushing roller to produce coal samples. The double-roll crusher is usually equipped with an active roller and a passive roller, which are called "double rollers". The particle size of the coal sample particles after crushing can be controlled by adjusting the distance between the double rollers. Before adjusting the gap between the double rollers, the two need to be zeroed, that is, the two are close to each other.

[0003] Known Chinese Publicly Authorized Inventions: (Publication No.: CN209205411U) discloses a double-roll crusher, including a gap adjustment mechanism, the gap adjustment mechanism is provided with an adjusting screw, and also includes a driving mechanism that rotates the adjusting screw to change the gap between the active roller and the passive roller, and a torque limiter is provided between the driving mechanism and the adjusting screw. In the double-roll crusher provided by the present invention, the driving mechanism is connected to the adjusting screw, and the driving mechanism drives the adjusting screw to rotate, thereby changing the distance between the two rollers. When the active roller and the passive roller are moved together, the gap between the rollers is zero. The driving mechanism continues to rotate, and because the gap between the two rollers is zero, the adjusting screw cannot rotate. At this time, the torque will increase sharply. When the torque limiter reaches the limit torque, slippage occurs, and the driving mechanism stops rotating, thereby realizing automatic alignment of the zero position of the two rollers.

[0004] However, in the implementation of the relevant technology, it was found that the above-mentioned disclosed technology has the following problems: it is difficult to adjust the distance between the two squeezing rollers, which makes it inconvenient to adjust the required crushing size, and it is difficult to detect and adjust the tightness of the synchronous belt generated by adjusting the two squeezing rollers, resulting in the two squeezing rollers being unable to rotate, thereby reducing the rotation stability of the squeezing rollers. Therefore, a fine rocker arm roller machine is proposed. Summary of the invention
