The specific operation flow is as follows:

the material is placed on the guide rail 21 and moves downwards along the guide rail to extrude the movable sliding block 24, the sixth elastic part 26 is compressed at the same time, the material is positioned at the position of the movable block 52 at the moment, the movable block is positioned at the position with higher axis of the material at the moment, the rotation of the first motor 33 drives the threaded rod 34 to rotate, the threaded rod is meshed with the threaded block 55, the third sliding block 76 is clamped into the first clamping port 58 at the moment to fix the threaded block, the rotation of the threaded rod drives the threaded block to move outwards at the moment, the threaded block is in a static state relative to the movable block under the fixation of the third sliding block at the moment, so the rotation of the threaded rod drives the whole movable block to move outwards, the first sliding block 53 on the movable block moves outwards along the first sliding groove 51, the front part of the movable block is inserted into the middle upper position in the tubular object at the moment, the pressing block 93 is continuously extruded in the process that the first sliding block moves to the bottom of the first sliding groove, the pressing block continuously rotates around the second rotating piece 92, but the rotating block is fixed by the fifth sliding block 99, so that the pressing block cannot rotate, the pressing block is continuously embedded into the sixth cavity 91, the fourth sliding block 97 on the pressing block extrudes the first extrusion block 911 on the fifth sliding block, which is clamped into the third sliding groove 96, so that the fifth sliding block is extruded to move upwards, the fifth sliding block moves upwards to unlock the fixing of the rotating block, at the moment, the rotating block rotates around the first rotating piece, so that the unlocking of the thread block is realized, in the rotating process of the rotating block, as the second extrusion block 912 is wider than the third sliding groove, the first extrusion block cannot be clamped into the third sliding groove again, at the moment, the spring plays a reset role, the rotating block is extruded outwards, so that the rotating block rotates around the first rotating piece under the pushing action, and rotates in the fourth cavity 71, so that the third slider is rotated out from the first clamping port 58, thereby unlocking the locking of the screw block, the screw block will move outwards along the axial direction, when the screw block moves into the rotating block 82, the rotating block will be driven to rotate by the rotation of the screw block due to the light weight of the rotating block and the moving block, at this time, the upper oblique strip 83 will be driven to move by the rotation of the rotating block, the sixth slider 84 which is matched with the oblique strip through the oblique groove 85 will approach to the third rotating member 87 along the through groove, at this time, the second rotating rod 811 plays a supporting role to support the first rotating rod to rotate, thereby the first rotating rod is spread outwards to clamp the object, at this time, the fourth elastic member 104 applies force to the seventh slider, thereby the screw block receives axial resistance to drive the rotating block to rotate, when the sixth slider 84 reaches the limit, namely after the clamping of the object is completed, at the moment, the rotating block can not rotate, so that the thread block can not rotate, at the moment, the clamping state is completed, so that the thread block continuously extrudes the seventh sliding block 102, so that the seventh sliding block continuously moves and protrudes outwards, the thread block can not axially move again after finally reaching the limit distance and rotates, the rotating process is in contact with the convex block, so that the whole moving block is driven to rotate, so that the object is driven to rotate at a constant speed, then the spraying process is carried out, the drying nozzle 62 continuously dries the surface of the object in the process, after the spraying process is finished, the drying is carried out for a period of time, then the motor is reversely rotated, at the moment, the eighth sliding block outwards extends due to no extrusion of the thread block, so that the effect of limiting the moving block is achieved, the thread block is preferentially retracted inwards, so that the thread block returns into the rotating block and rotates reversely, thereby accomodate back first swing arm, get back to the inside one end of second cavity as the screw thread piece to thereby extrude the ninth slider and control the eighth slider and retract, thereby the movable block will touch the chamfer on the first spout at the rotation in-process and reset along first spout this moment, and the article will fall this moment, and later along the guide rail unloading, above-mentioned step is repeated.
