[0007] Furthermore, the interior of the bladder accumulator is filled with nitrogen, and the bearing pressure of the bladder accumulator is 10 tons.

[0008] Furthermore, the bladder accumulator includes a shell, a capsule is arranged in the shell, an inflation nozzle is arranged on the top of the capsule, an inflation nozzle protective cover is arranged on the inflation nozzle, and the bottom of the capsule is connected to the bladder stop valve.

[0009] Furthermore, the capsule stop valve includes a valve seat, the top of which is connected to the outer shell through a connecting pipe, the bottom of which is connected to the oil inlet of the oil cylinder through which the oil rod of the oil cylinder extends, a control handle passing through the valve seat is provided on one side of the valve seat, and an elastic plug is provided in the connecting pipe.

[0010] Furthermore, an oil inlet for retracting the oil rod of the oil cylinder is provided at one end of the oil cylinder close to the oil rod of the oil cylinder.

[0011] When the roller ring pressure is greater than a preset value when the present invention is used, the nitrogen in the bladder accumulator is compressed, and the roller ring gap is automatically adjusted until the pressure value is within a safe range. The present invention automatically adjusts the size of the roller ring gap as the pressure changes, preventing foreign objects such as iron blocks from falling into the equipment, and effectively protecting the safety of the double-roll machine equipment.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0017] like Figures 1 to 3 As shown, this embodiment provides an automatic adjustment device for the roller ring of a roller mill, including an adjustment connecting seat, on which a cylinder is fixedly installed via a connecting structure, one end of the cylinder is connected to a bladder accumulator, on which a bladder stop valve is provided, and the other end of the cylinder is provided with a cylinder rod, one side of the cylinder rod is provided with a positioning seat, on which a roller ring bearing seat of the roller mill is connected, and on which a roller ring bearing of the roller mill is provided.

[0018] When in use, the roller pressure is greater than the preset value. At this time, the nitrogen in the bladder accumulator is compressed and the roller gap is automatically adjusted until the pressure value is within a safe range. The size of the roller gap is automatically adjusted as the pressure changes to prevent foreign objects such as iron blocks from falling into the equipment, effectively protecting the safety of the double-roller machine equipment.

[0019] Furthermore, the connection structure includes hexagonal screws located on both sides of the oil cylinder and screwed on the adjustment connection seat, a flat washer is provided between the hexagonal screw and the adjustment connection seat, and a spring washer is provided between the flat washer and the hexagonal screw.
