The working process of the invention is as follows:

a. the gas bottle cover is sleeved on the gas bottle cover of the conveying belt, and the driving belt wheel is driven to rotate to drive the gas bottle cover on the conveying belt to move towards the introducing port of the straightening channel; when the gas cylinder cover moves to the guide inlet, the gas cylinder cover of the outer joint deviates from the straightening channel and is poked and twisted by the arc-shaped outer end part of the baffle plate, so that the gas cylinder cover can smoothly enter the straightening channel, the outer joint of the gas cylinder cover entering the straightening channel is straightened by the baffle plates on the two sides to the same direction, and then the straightened gas cylinder cover moves to the tail end of the gas cylinder cover conveying straightening device along with the outlet of the conveying belt from the inner end of the straightening channel;

b. when the gas bottle cap moves towards the tail end of the gas bottle cap conveying and straightening device, the gas bottle conveying device drives the gas bottle placed on the gas bottle conveying belt to move towards the self-centering bottle holding device, when the gas bottle moves to the middle of the two sliding table bottle holding devices, the motor is started to drive the long lead screw to rotate, and because the external threads with opposite directions and same size at the two ends of the long lead screw are respectively connected with the lead screw nuts at the bottom surfaces of the two sliding table bottle holding devices, the two sliding table bottle holding devices can be pulled to move towards each other at the same speed along the sliding rails when the long lead screw rotates; when the two sliding table bottle holding devices move oppositely at the same speed, the clamping devices arranged at the upper ends of the two sliding table bottle holding devices also move oppositely at the same speed to drive the two pairs of rubber clamping blocks corresponding to the two sides to move oppositely to hold the gas cylinder;

c. when the gas cylinder is held and fixed by the self-centering cylinder holding device, the workpiece taking mechanical arm is driven to rotate to grab the gas cylinder cover which is straightened and moved to the tail end of the straightening device, and then the mechanical arm rotates to move the gas cylinder cover to the middle of the gas cylinder and a lever clamping clamp above the gas cylinder;
