The lower end of the lifting and rotating mechanism 2 is fixedly mounted on the frame 1, and the upper end is movably connected to the frame 1 through a balancing assembly 5. The balancing assembly 5 reduces the eccentric load on the lifting and rotating mechanism 2, which helps to reduce the deformation of the lifting and rotating mechanism 2 during the station switching process, and helps to extend the service life of the lifting and rotating mechanism 2.

When in use, a reel is placed on the wire-receiving drive mechanism 6 and the idle positioning mechanism 3, and the reel thereon is driven to rotate by the wire-receiving drive mechanism 6 to reel in. After the reeling is completed, the lifting and rotating mechanism 2 is used to lift and rotate the support plate component 4, so that the reel at the working position and the reel at the idle position are swapped.

[0035] The wire-receiving drive mechanism 6 comprises a motor, a sleeve A60 and a drive shaft 61. The motor and the sleeve A60 are mounted on the frame 1. The middle part of the drive shaft 61 is connected to the sleeve A60 through a tapered roller bearing. The upper end of the drive shaft 61 is provided with a bearing plate 62.

When in use, the end plates at both ends of the reel are processed with clamping holes at positions corresponding to the anti-skid component 7, and the stepped shaft extends into the clamping holes under the action of the spring force of the spring, thereby preventing the reel from slipping relative to the bearing plate 62 during the winding process.

[0037] The idle positioning mechanism 3 includes a support tube 31 and a conical positioning top 33. The lower end of the support tube 31 is connected to the frame 1 through a mounting plate B30, and the upper end is provided with a support plate 32.

The conical positioning top 33 is connected to the upper end of the support tube 31 through a bolt. When in use, the conical positioning top 33 is used to position the lower end of the reel, and the support plate 32 is used to support the reel.

[0038] The support plate assembly 4 includes a sleeve B40 and a support plate 41. A keyway is provided on the inner wall of the sleeve B40 in the axial direction. The support plate 41 is mounted on the sleeve B40. A conical reinforcement sleeve 42 is provided on the support plate 41 at a position coaxial with the sleeve B40. The conical reinforcement sleeve 42 is connected to the support plate 41 through a plurality of reinforcement plates 43.

The support plate 41 is used to lift and rotate the reel on the working position and the idle position.

[0040] A rotary encoder is installed on the swing cylinder 27, and a switch mounting plate is provided at the bottom of the fixed plate 20, and two-stroke switches A21 are provided on the switch mounting plate. When in use, the rotary encoder is used to detect the rotation angle of the main shaft of the swing cylinder 27, and the two-stroke switch A21 is used to detect the lifting stroke of the lifting plate B26. When it is necessary to switch the reel on the working position and the idle position, the piston rod of the cylinder 25 is retracted, driving the lifting plate B26, the swing cylinder 27, the lifting sleeve B23 and the rotating drive shaft 24 to move upward as a whole, and the support plate 41 is lifted upward by a certain displacement to lift the reel, so that the reel is separated from the winding drive mechanism 6, and the reel on the idle position is separated from the idle positioning mechanism 3, and then the swing cylinder 27 is actuated to drive the rotating drive shaft 24 to drive the support plate 41 to rotate 180 degrees, thereby realizing the position swap of the reel on the working position and the idle position.

[0041] The balancing assembly 5 includes a balancing cylinder 50 , and the balancing cylinder 50 is connected to the frame 1 via a connecting plate 51 .

[0042] The balancing cylinder 50 is movably connected to the upper end of the rotating driving shaft 24 via a needle bearing.

[0043] Specifically, the vertical double-station wire-taking machine further includes a controller, which is electrically connected to the motor, the swing cylinder 27, the rotary encoder, and the travel switch A21 in the wire-taking drive mechanism 6.

[0044] The working principle or working process of the double-station switching device of the vertical wire-taking machine described in the present invention is as follows:

[0045] (1) Place an empty reel on the support plate 32 in the idle position, and rotate the reel around the central axis of the conical positioning tip 33 until the upper end of the elastic positioning component 8 is engaged with the clamping hole on the reel;

[0047] (3) The swing cylinder 27 drives the support plate 41 to rotate 180 degrees by rotating the drive shaft 24, thereby rotating the reel in the idle position to the working position;

[0048] (4) The oil cylinder 25 is actuated to drive the lifting plate B26, the swing oil cylinder 27, the lifting sleeve B23 and the rotating drive shaft 24 to move downward as a whole. The support plate 41 moves downward under its own weight, placing the reel on the bearing plate 62, and the upper end of the anti-skid component 7 is aligned and inserted into the clamping hole at the lower end of the reel.

[0049] (5) Fix one end of the steel wire on the drum;

[0050] (6) Starting the motor, the motor drives the drive shaft 61 to rotate through the belt drive, thereby driving the carrier plate 62 and the reel on the carrier plate 62 to rotate to take up the line;

[0051] (7) After the reel is fully wound with steel wire, turn off the motor, trim the steel wire, and then insert the end of the steel wire into the clamping hole at the upper end of the reel;
