semi-pressure release state: when the half pressure release limiting hook 4 is positioned at the right side, the handle 2 is lifted to rotate clockwise, and after the handle 2 and the locking piece 10 pass through the dead center position, the clamping strip 19 stops the half pressure release limiting hook 4 from continuing to rotate, so that the handle 2 and the cradle body 1 are prevented from continuing to rotate clockwise, and the cradle is in a half pressure release state.
When a plurality of groups of rocking frames are driven to wholly and semi-release pressure at the same time, whether a threaded rod 2104 needs to be moved is checked according to the actual situation (namely, whether a semi-release pressure limiting piece is positioned on the right side or not), if so, the threaded rod 2104 is moved towards the direction close to a vertical moving frame 2002 by a small distance until a positioning plate 25 is moved to be in contact with the side wall of a left clamping plate 24, at the moment, a bevel gear B2105 is meshed with a bevel gear A2103, a stepping motor is started to drive a rotating rod 2004 to rotate so as to drive a half gear 2005 to rotate, the meshing of the half gear 2005 and an inner gear hobbing drives an external gear 2101 to rotate in the upward process of the outer gear hobbing of the outer side wall of the vertical moving frame 2002, then the bevel gear B2105 is driven to rotate through the bevel gear A2103, the threaded rod 2104 rotates along with the bevel gear B2105 and simultaneously drives a contact plate 2106 to right side, the contact plate 2106 and a reset spring B22 push an end cover 3 to right side, and then the semi-release pressure limiting hook 4 is moved to the right side position, in the upward process of the vertical moving frame 2002, and the contact rod 2007 is driven to move upward by a transverse plate 2007, and the handle 2007 is pushed upward by the handle 2007 and the reset spring A2; when the half pressure release limiting piece is positioned on the right side, the threaded rod 2104 is not required to be moved, the stepping motor is directly started, after the handle 2 and the locking piece 10 pass through the dead center position, the clamping strip 19 stops the half pressure release limiting hook 4 from continuously rotating, the handle 2 and the cradle body 1 are prevented from continuously rotating clockwise, the cradle is in a half pressure release state at the moment, and the reset spring A2008 and the reset spring B22 are arranged so that the single cradle can be conveniently and independently controlled.
Pressure relief state: when the half pressure release limiting hook 4 is positioned at the left side, the clamping strip 19 can not block the half pressure release limiting hook 4 when the handle 2 is lifted, and the cradle can be completely lifted by lifting the handle 2, thereby being convenient for cleaning and maintaining the spinning frame, yarn breakage joint, loading and unloading the upper roller 18, replacing the lower roller 17 and the like.
If the half pressure release limiting piece is positioned at the left side (at the moment, the position of the threaded rod 2104 is adjusted until the bevel gear A2103 is not meshed with the bevel gear B2105, namely the positioning plate 25 is contacted with the right clamping plate 24), the stepping motor is started to drive the rotating rod 2004 to rotate, and the vertical movement frame 2002 is driven to move upwards through the cooperation of all parts of the vertical movement mechanism, so that the pressure release of the multiple groups of rocking frames can be completed.
State transition: when the whole cradle is in a half pressure release state, after the cradle is pressurized again, the half pressure release limiting hook 4 is pulled to the left side, the handle 2 is lifted again, the half pressure release limiting hook 4 can smoothly pass through the cradle body 1, and the cradle is automatically unlocked to be in a pressure release state; the conversion of the cradle semi-pressure release and pressure relief functions is realized.
When the whole pressure relief of a plurality of groups of rocking frames is driven, according to the actual situation (namely whether the semi-pressure relief limiting piece is positioned at the left side) whether the position of the transverse moving mechanism is required to be adjusted or not, when the transverse moving mechanism is required to be adjusted, the stepping motor is started to drive the rotary rod 2004 to rotate, all parts of the vertical moving mechanism are matched to drive the vertical moving frame 2002 to move upwards until the rocking frames are in a semi-pressure relief state, the threaded rod 2104 is moved towards the direction close to the vertical moving frame 2002 for a small distance until the positioning plate 25 is moved to be in contact with the side wall of the left clamping plate 24, at the moment, the bevel gear B2105 is meshed with the bevel gear A2103, the stepping motor continues to rotate to enable the half gear 2005 to be meshed with the other internal gear, namely, the vertical moving frame 2002 is driven to move downwards, in the process of the vertical moving frame 2002 is driven to rotate through the external gear 2101, then the external gear A2103 is driven to rotate through the bevel gear A2105, the threaded rod 2104 is driven to move along with the bevel gear B2105, the threaded rod 2106 is driven to move leftwards along with the vertical moving frame, the threaded rod 2106 and the reset spring B22 is further pushed to move leftwards along with the threaded rod 2106 until the semi-pressure relief limiting hook 4 is moved to the left side to be in the left position, and then the positioning plate is moved to be in contact with the left side of the vertical moving plate 24, and the positioning plate 2104 is further moved towards the direction far from the vertical moving plate 24 to be in the direction away from the left side of the vertical moving direction of the vertical moving plate 24, and is not in contact with the vertical moving side with the side of the clamping plate 2103, and the left side is meshed with the left side, and can be in contact with the left side is kept in contact with the left, and is moved.
