[0047] The working principle of the above technical solution is as follows: the rotation path of the tungsten wire is to start the driving wheel 29, drive the tungsten wire to pass through between the longitudinal wheel 21 and the driving wheel 29 on the first triangular tungsten wire bracket 19, and go to the longitudinal wheel 21 of the next triangular tungsten wire bracket 19, drive the longitudinal wheel 21 to rotate, pass through the left side of the transverse wheel 26, drive the transverse wheel 26 to rotate, pass through the rotating belt 24, drive the transmission between the rotating belt 24 and the rotating wheel 25, drive the rotating wheel 25 and the triangular tungsten wire bracket 19 to rotate, and the tungsten wire passes through the right side of the transverse wheel 1 22, drive the transverse wheel 1 22 to rotate, and the tungsten wire bypasses the longitudinal wheel 1 20, vertically downwards around the longitudinal wheel 21 of the next triangular tungsten wire bracket 19, and is consistent with the second surrounding method, until the four triangular tungsten wire brackets 19 are surrounded, and then pass through the adjusting component to return between the longitudinal wheel 21 and the driving wheel 29, thereby completing a circle of movement, and a transverse tungsten wire 30 is stretched out between the two transverse triangular tungsten wire brackets 19, and a longitudinal tungsten wire 31 is stretched out between the two longitudinal triangular tungsten wire brackets 19;

[0048] The single crystal silicon rod enters the support shell 1 from the entrance 2, and the front end of the single crystal silicon rod contacts the four pulleys 2 18, squeezing the four pulleys 2 18 to expand outward, driving the four pulley support rods 2 17 to undergo elastic deformation and bend outward, and the single crystal silicon rod continues to move forward, driving the four pulleys 2 18 to contact the surface of the single crystal silicon rod and rotate with it, and the four pulleys 2 18 limit the single crystal silicon rod in the middle of the four support columns 4, and the single crystal silicon rod continues to move forward, driving the four pulleys 2 18 to rotate, and the front end of the single crystal silicon rod contacts the four pulleys 16, driving the four pulley support rods 15 to undergo elastic deformation and bend outward, and the single crystal silicon rod continues to move forward, driving the four pulleys 16 to contact the single crystal silicon rod surface and rotate with it.

[0050] The purpose of the baffle 1 23 is to prevent the tungsten wire from jumping out of the triangular tungsten wire support 19 during operation.

[0055] The adjusting component includes a second motor 33, which is fixed to the side of the supporting shell 1, a screw 34 is connected to the output end of the second motor 33, the screw 34 is threadedly connected to the moving rod 35, the moving rod 35 is fixed to the second pulley support rod 17, the screw 34 is rotatably connected to the fixed rod 36, the fixed rod 36 is fixed to the side of the supporting shell 1, a slide tube 37 is slidably connected to the fixed rod 36, a spring 38 is provided between the fixed rod 36 and the slide tube 37, an elastic clamping piece 42 is fixed in the slide tube 37, and the front end of the elastic clamping piece 42 is connected to the slide tube 37. A spring 2 43 is provided between the inner walls of the sliding tube 37, the fixing rod 36 is rotatably connected to the ratchet 41, the ratchet 41 is clamped and connected to the elastic locking piece 42, the ratchet 41 is fixedly connected to the tensioning rod 40, and the tensioning rod 40 has longitudinal wheels 3 44 and longitudinal wheels 45 rotatably connected on both sides, two transverse wheel pillars 2 47 are fixed to the side of the tensioning rod 40, and transverse wheels 3 46 and transverse wheels 48 are rotatably connected to the two transverse wheel pillars 2 47 respectively, baffles 2 49 are rotatably connected to the two transverse wheel pillars 2 47, and a pull rod 39 is fixed to the sliding tube 37.

[0056] The working principle of the above technical solution: the square opening size of the single crystal silicon rod can be adjusted. The specific adjustment is that when the square opening size needs to be reduced, the motor 2 33 is started to drive the screw 34 to rotate, drive the moving rod 35 to move toward the direction near the entrance 2, drive the pulley support rod 2 17 to move toward the direction near the entrance 2, drive the pulley support rod 2 17 and the pulley 1 16 to slide, the pulley support rod 2 17 pushes the connecting rod 12 and the connecting rod 2 13 to move toward the direction near the entrance 2, drive the slide 1 6 and the slide 2 10 on the support column 4 to move toward the direction near the entrance 2, thereby increasing the distance between the slide 1 6 and the fixed frame 1 7, increasing the distance between the slide 2 10 and the fixed frame 2 11, driving the rotating rod 1 8 and the rotating rod 2 9 to rotate, thereby shortening the distance between the upper and lower adjacent support columns 4, driving the connecting rod 1 12 and the connecting rod 2 13 to slide, and the other two adjacent support columns 4 are shortened in the same way as above. , driving the four support columns 4 to gather in the middle of the slide slot 5, and then driving the four triangular tungsten wire brackets 19 to gather in the middle. At this time, the tungsten wire is in a relaxed state, and the tensioning rod 40 is pushed outward, so that the ratchet 41 at the end of the tensioning rod 40 and the fixing rod 36 rotate, driving the upper end of the tensioning rod 40 to move outward, driving the longitudinal wheel three 44 to move outward, thereby increasing the distance between the longitudinal wheel three 44 and the rotating belt 24 on the triangular tungsten wire bracket 19 equipped with the motor one 28, and then tightening the relaxed tungsten wire. When the ratchet 41 and the fixing rod 36 rotate, the ratchet 41 and the elastic clamping piece 42 rub against each other. Under the elastic force of the spring two 43, the elastic clamping piece 42 is clamped into the tooth groove of the ratchet 41, which prevents the tensioning rod 40 from automatically rotating inward, causing the tungsten wire to relax. At this time, the distance between the two horizontal tungsten wires 30 is reduced, and the distance between the two longitudinal tungsten wires 31 is reduced, thereby reducing the size of the square root;

[0057] When the square opening size needs to be enlarged, the pull rod 39 is pulled in the direction of the screw rod 34, driving the slide tube 37 to move in the direction of the screw rod 34, driving the spring 1 38 to be compressed, driving the elastic blocking piece 42 and the spring 2 43 to move together with the slide tube 37 in the direction of the screw rod 34, driving the elastic blocking piece 42 to separate from the ratchet 41. At this time, the ratchet 41 is not restricted by the elastic blocking piece 42, and the tensioning rod 40 is rotated inward to shorten the distance between the vertical wheel 3 44 and the rotating belt 24 on the triangular tungsten wire bracket 19 equipped with the motor 1 28. At this time, the tungsten wire is in a relaxed state, and the motor 2 33 is started to drive the screw 34 to rotate, driving the moving rod 35 to move in the direction of the outlet 3, driving the pulley support rod 2 17 to move in the direction of the outlet 3, driving the pulley support rod 2 17 and the pulley 1 16 to slide, and the pulley support rod 2 17 pushes the connecting rod 1 12 and the connecting rod 2 13 to move in the direction of the outlet 3, driving the slide The first and second slides 16 and 10 move on the support column 4 toward the outlet 3, thereby reducing the distance between the slide 16 and the fixed frame 17, and reducing the distance between the slide 2 10 and the fixed frame 2 11, driving the rotating rod 1 8 and the rotating rod 2 9 to rotate, thereby increasing the distance between the upper and lower adjacent support columns 4, driving the connecting rod 12 and the connecting rod 2 13 to slide, and the other two adjacent support columns 4 increase the distance in the same way as above, driving the four support columns 4 to expand outward in the slide groove 5, and then driving the four triangular tungsten wire brackets 19 to expand outward. At this time, the tungsten wire can be stretched out, and the tensioning rod 40 is pushed outward to increase the distance between the longitudinal wheel 3 44 and the rotating belt 24 on the triangular tungsten wire bracket 19 equipped with the motor 1 28, and further tighten the tungsten wire. At this time, the distance between the two horizontal tungsten wires 30 is increased, and the distance between the two vertical tungsten wires 31 is increased, thereby increasing the size of the square.

[0058] In addition, the pulley support rod 15 and the pulley support rod 2 17 have a certain elasticity, which increases or decreases the distance between the pulley 2 18 on the opposite sides or increases or decreases the distance between the pulley 1 16 on the opposite sides, without affecting the clamping of the single crystal silicon rod;

[0059] The horizontal wheel three 46 and the horizontal wheel four 48 are both rotatably connected to the tungsten wire. The functions of the horizontal wheel three 46 and the horizontal wheel four 48 are the same as those of the horizontal wheel one 22 and the horizontal wheel two 26 .

The coolant is sprayed at the cutting position of the tungsten wire and the single crystal silicon rod. The function of the coolant is to reduce the temperature of the single crystal silicon rod and the tungsten wire, and at the same time wash away the single crystal silicon rod debris.
