The second annular shell 71 is sleeved on the shaft sleeve 11 of the side drum 1 in a matching manner, the outside of the second annular shell 71 is fixedly connected with the connecting key 5, and the second annular shell 71 can slide on the shaft sleeve 11 under the driving of the connecting key 5; an inner cavity is formed in the second annular shell 71, a second annular piston 72 is slidably mounted in the inner cavity, the inner cavity is divided into a second left air cavity and a second right air cavity by the second annular piston 72, the second left air cavity and the second right air cavity are both connected with a second air pump, and the second annular piston 72 can be driven to move left and right by inflating and deflating the second left air cavity and the second right air cavity by the second air pump; the lower portion of the second annular piston 72 is formed with a tapered surface and is defined as a second annular piston 72 tapered surface; a plurality of round holes are uniformly distributed on the inner wall of the second annular shell 71 in the circumferential direction, the diameter of each round hole is larger than the height of the round hole, a steel ball 73 is placed in each round hole, the diameter of each steel ball 73 is the same as that of the round hole, the steel balls 73 can move in the round holes, the upper parts of the steel balls 73 placed in the round holes are in conical surface contact with the second annular piston 72, correspondingly, a plurality of conical grooves 111 are uniformly distributed on each shaft sleeve 11 in the circumferential direction, the number of the conical grooves 111 is the same as that of the steel balls 73, and the conical grooves 111 and the steel balls 73 are matched for use in a one-to-one correspondence manner.
The movement of the second annular housing 71 is effected by a servo motor driving the main lead screw 3, the position of the second annular housing 71 being accurately given by a servo system. When the circular hole on the second annular housing 71 is aligned with the tapered groove 111 on the shaft sleeve 11, the second air pump inflates the second right air chamber, the second annular piston 72 moves leftwards, the tapered surface of the second annular piston 72 presses the steel ball 73 into the tapered groove 111 on the shaft sleeve 11, at this time, the second annular housing 71 is locked on the shaft sleeve 11, and the connecting key 5 and the anti-packing rod set 6 are also locked on the shaft sleeve 11 because the connecting key 5 and the anti-packing rod set 6 are both fixedly connected with the second annular housing 71, as shown in fig. 3. Due to the proper small angle of the conical surface of the second annular piston 72, the mechanism has certain self-locking performance, and the second annular shell 71 can be stably positioned by providing smaller inflation pressure for the second right air cavity; and the positioning of the positioning device 7 has a self-centering effect, so that the accumulated error in the repeated walking process of the servo system can be compensated, and the second annular shell 71 can be positioned at the same position of the corresponding shaft sleeve 11 all the time, so as to ensure that the reverse-wrapping rod group 6 always has the same initial position on the corresponding shaft sleeve 11. After the second air pump inflates air to the second left air cavity, the second annular piston 72 moves rightwards, and at the moment, the positioning device 7 enters a non-positioning state (namely a locking state is released), because a space for accommodating the steel ball 73 is just arranged between the shaft sleeve 11 and the second annular piston 72 (the space is not communicated with the second left air cavity and the second right air cavity), when the second annular shell 71 moves towards any direction of two sides, the steel ball 73 can be naturally pushed and lifted along the inclined wall surface of the tapered groove 111 and enters the space for accommodating the steel ball 73, and then the second annular shell 71 can freely move along the axial direction without obstruction, so that the reverse packing rod group 6 can move relative to the shaft sleeve 11, and conditions are provided for the reverse packing rod group 6 to perform reverse packing operation.
Furthermore, a plurality of supporting grooves 74 are uniformly distributed on the outer wall of the second annular shell 71 in the circumferential direction, the number of the supporting grooves 74 is the same as the number of the turn-up rods 62 in the turn-up rod group 6, each supporting groove 74 is matched with each turn-up rod 62 in a one-to-one correspondence manner for use, and each supporting groove 74 is used for accommodating and supporting each turn-up rod 62 in the turn-up rod group 6 in the contracted state.
Further, in order to ensure that the second annular piston 72 can be smoothly installed in the second annular housing 71, the second annular housing 71 may be divided reasonably, and then the second annular piston 72 is hermetically assembled after being installed.
