[0022] See also Figure 1-5 As shown, a device for cutting silicon cores for polysilicon processing comprises a cutting table 1, a pushing plate 2 is slidably connected to the rear of the top of the cutting table 1, a fixing frame 3 is bolted to the top of the left and right sides of the cutting table 1, and a driving structure 4 is arranged inside the fixing frame 3, fixing plates 5 are fixed to the upper and lower parts of the left and right sides of the cutting table 1, and a linkage structure 6 is arranged between the fixing plates 5, a feeding table 7 is arranged below the front of the cutting table 1, and a waste box 8 is clamped below the feeding table 7, a plurality of through holes 9 are opened on the surface of the top of the feeding table 7, a reset structure 10 is arranged on the left and right sides of the feeding table 7, rollers 11 are fixed to the rear of the left and right sides of the waste box 8, and guide rails 12 are fixed to the left and right sides of the front of the cutting table 1.

[0023] The driving structure 4 includes a first threaded rod 41, a motor 42, a first threaded sleeve 43 and a connecting rod 44. The first threaded rod 41 is rotatably connected to the inside of the fixing frame 3. The motor 42 is fixed to the back of the fixing frame 3, and the output shaft of the motor 42 passes through the fixing frame 3 and is fixedly connected to the rear end of the first threaded rod 41. The first threaded sleeve 43 is threadedly connected to the rear of the surface of the first threaded rod 41. The connecting rod 44 is fixed to the top of the first threaded sleeve 43, and the other end of the connecting rod 44 is fixedly connected to the push plate 2. A limiting groove 13 is provided at the bottom of the wall, a limiting block 14 is fixed at the bottom of the first threaded sleeve 43, and the lower part of the limiting block 14 extends to the inside of the limiting groove 13 and is slidably connected to the inner wall of the limiting groove 13. When the motor 42 is turned on, the output shaft of the motor 42 will drive the first threaded rod 41 to rotate, and the first threaded sleeve 43 on the surface of the first threaded rod 41 drives the upper push plate 2 to move forward through the connecting rod 44, thereby pushing the polycrystalline silicon core on the surface of the cutting table 1 forward, and then unloading the polycrystalline silicon core.

[0024] The linkage structure 6 includes a first bevel gear 61, a second threaded rod 62, a second bevel gear 63, a second threaded sleeve 64 and a fixed rod 65. The first bevel gear 61 is rotatably connected to the front side of the fixed frame 3, and the front end of the first threaded rod 41 passes through the fixed frame 3 and is fixedly connected to the rear side of the first bevel gear 61. The second threaded rod 62 is rotatably connected between the fixed plates 5. The second bevel gear 63 is rotatably connected to the surface of the upper fixed plate 5, and the top end of the second threaded rod 62 passes through the fixed plate 5 and is fixedly connected to the bottom of the second bevel gear 63. The first bevel gear 61 is meshed with the second bevel gear 63. The second threaded sleeve 64 is threadedly connected to the lower surface of the second threaded rod 62. The fixed rod 65 is fixed to the surface of one side of the second threaded sleeve 64. When the push plate 2 moves forward, the first bevel gear 61 also drives the second bevel gear 63 to rotate, so that the second threaded rod 62 below starts to rotate, and the fixed rods 65 on both sides are used to move the unloading platform 7 upward so as to receive the unloaded polysilicon cores.

[0025] The reset structure 10 includes a slide groove 101, a slider 102 and a spring 103. The slide groove 101 is opened at the rear of the left and right sides of the unloading platform 7. The slider 102 is slidably connected to the rear side of the inner wall of the slide groove 101, and one end of the fixed rod 65 is fixedly connected to the surface of the slider 102. The spring 103 is fixed at the upper and lower sides of the front side of the slider 102, and the front end of the spring 103 is fixedly connected to the inner wall of the slide groove 101. When the fixed rod 65 drives the slider 102 to move upward, the unloading platform 7 will rise as a whole. As the unloading platform 7 moves upward, the roller 11 also rolls on the surface of the guide rail 12, causing the unloading platform 7 to move. As the spring 103 contracts and stretches, the unloading platform 7 shakes back and forth during the rising process.

[0026] A plurality of protrusions are arranged on the surface of the guide rail 12, and the protrusions are arranged in an arc shape. The roller 11 fits the surface of the guide rail 12. Baffles 15 are fixed on the front and rear sides of the top of the unloading platform 7. When the unloading platform 7 rises or falls, the baffles 15 on the front and rear sides can shield the polycrystalline silicon core to prevent the polycrystalline silicon core from falling.

[0027] Working principle: When the staff has finished cutting the polysilicon core, they will turn on the motors 42 on both sides of the rear, so that the push plate 2 moves forward, and the unloading table 7 at the front side also rises. As the push plate 2 continues to move forward, the polysilicon cores on the surface of the cutting table 1 that have been cut are pushed onto the top of the unloading table 7, and the debris on the surface of the cutting table 1 also falls on the surface of the unloading table 7. Then the staff controls the rotation direction of the output shaft of the motor 42, so that the push plate 2 moves backward again, and the unloading table 7 The roller 11 rolls on the surface of the guide rail 12, causing the unloading platform 7 to shake in the front and rear directions. As the unloading platform 7 continues to shake, the polysilicon cores and polysilicon debris on the surface of the unloading platform 7 also move, and the debris falls into the through holes 9 on the surface of the unloading platform 7, and finally falls into the waste box 8 for temporary storage. After the unloading platform 7 falls to its original position, the staff can remove the polysilicon cores that have been cut on the surface of the unloading platform 7, thus completing the unloading operation of the polysilicon cores.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
