[0022] The rotating shaft 5 , the transition block 7 , the counterweight arm 8 and the pulley arm 10 are connected as a whole and rotate together with the rotating shaft 5 .

[0023] The weight of the counterweight block 9 is balanced with the weight of the counterweight arm, the pulley arm and the pulley, so that the installed components on the rotating shaft can be suspended at any angle position. The counterweight block 9 is arranged above the bearing seat 4.

[0024] The groove of the top edge of the outer diameter of the pulley 11 is on the axis of the rotating shaft 5.

[0025] The upper part of the slide table 3 is connected to the side rails of the linear module 2 .

[0026] The lower side surface of the slide 3 is fixedly connected to the bearing seat 4.

[0027] The bearing seat 4 is provided with two deep groove ball bearings 6 sleeved on the rotating shaft 5 .

[0028] The transition block 7 is arranged on the left side of the outer part of the bearing seat 4 and is connected to the lower part of the broken line counterweight arm 8. The upper part of the broken line counterweight arm 8 is fixedly connected to the counterweight block 9 by bolts. The counterweight block 9 is arranged on the inner side of the counterweight arm 8.

[0030] The working principle of this utility model:

[0031] On the multi-wire cutting equipment, two groups of the utility model are respectively installed on both sides of the multi-wire cutting equipment. At the beginning of processing, the wire roller 13 on one side is full of wire, and the other side is an empty roller. During processing, the wire roller 13 rotates to take out the diamond wire 12 from the full-wire side, and at the same time, the wire arrangement device cooperates and reciprocates along the length direction of the wire roller 13 under the drive of the servo motor 1 on the linear module 2, always keeping the diamond wire 12 perpendicular to the axis of the wire roller shaft 13. After passing through the processing area, the wire is transferred to the empty roller side, and then the wire arrangement device on this side evenly winds the wire around the empty roller. As the processing progresses, the outer diameter of the wire roller 13 on the full-wire side is equivalent to being constantly reduced. Figure 3 The central wire arrangement device as a whole will rotate counterclockwise along the axis O of the rotating shaft 5. Similarly, the outer diameter of the wire roller 13 on the empty wire side gradually increases, and the wire arrangement device on the side rotates clockwise. Figure 3 In the view, the position of the wiring groove on the upper part of the pulley 11 remains unchanged at point O, so that the diamond wire 12 will not fall off; in addition, because the weight of the counterweight block 9 matches the weight of the entire device, the system can hover at any angle, so no extra external force will be applied to the diamond wire 12 during rotation, thereby avoiding the occurrence of line drop and line breakage.

[0032] The utility model realizes the stable arrangement of diamond wires on wire rollers in multi-wire cutting equipment, greatly reducing the probability of wire breakage, wire dropping and the like. It has a simple structure and high reliability, and solves the technical problem of low reliability of similar structures. It can be used in related scenarios, facilitates wide promotion and application, and improves equipment processing efficiency.
