2. The working method of the intelligent capping machine for the coal samples as claimed in claim 1 is characterized by comprising the following steps:

the method comprises the following steps: the method comprises the following steps that uncovered sample bottles containing coal samples to be detected enter a conveyor belt (10) through a sorting device and move towards a capping machine under the action of the conveyor belt (10), and when the uncovered sample bottles enter the lower part of an intelligent capping machine, an identification module below the intelligent capping machine can identify the sizes of the sample bottles and transmit signals to a control module;

step two: the control module receives the information, determines the size of a bottle cap to be used, controls a bottle cap stack (3) to push out a correct bottle cap from a discharge hole (14) below the bottle cap stack, controls a servo motor (606) to rotate at the same time, enables the servo motor (606) to drive a sliding plate (602) to move towards a certain direction, drives a semicircular gear (603) to rotate through gear teeth on two sides of the sliding plate (602), drives a clamping ring (608) below the semicircular gear (603) to open towards one side in a splayed shape through a connecting rod (607), is matched with the bottle cap in the bottle cap stack (3) to enter, then reverses the servo motor (606), restores the clamping ring (608) to be circular, and at the moment, the bottle cap is surrounded inside by the clamping ring (608); meanwhile, the lower conveyer belt (10) conveys the uncovered sample bottles to the position right below the blanking hole (13);

step three: the pushing cylinder (402) moves to drive the fixture block (403) to tightly clamp the bottle body of the uncovered sample bottle, meanwhile, the lifting cylinder (5) works to push the bottle cap stabilizing mechanism (6) to descend, when the bottle cap stabilizing mechanism (6) descends until the bottle cap in the clamping ring (608) contacts the bottle body, the lifting cylinder (5) stops moving, then the sinking cylinder (701) is started to push out the outer rotor motor (702) and the rotating head (705) below the sinking cylinder (701), when the rotating head (705) contacts the bottle cap, the lifting cylinder (5) begins to contract to drive the bottle cap stabilizing mechanism (6) to start to rise, meanwhile, the sinking cylinder (701) extends out at the same speed as the lifting cylinder (5), the clamping ring (608) is separated from the side wall of the bottle cap while the position of the bottle cap is kept unchanged, then the outer rotor motor (702) rotates, and the bottle cap is driven to rotate and screw through the rotating head (705);

step four: after the bottle cap is screwed down, the sinking air cylinder (701) contracts to drive the rotating head (705) to push back to the upper part of the clamping ring (608); the pushing cylinder (402) contracts to drive the clamping block (403) to be separated from the bottle body, the conveyor belt (10) continues to move, and the sample bottle with the bottle cap screwed is sent out.
