In order to simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0034] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-Figure 9 As shown, an embodiment of the utility model provides a regular hexagonal silicon core cutting device, including a cutting box 100 for placing and processing regular hexagonal silicon cores, a cutting unit 200 for cutting the silicon cores is installed inside the cutting box 100, and an adjusting unit 300 for lifting and fixing the cutting unit 200 is movably installed on the upper end of the cutting unit 200.

[0036] The cutting unit 200 includes a mounting base 210 installed inside the cutting box 100 for supporting the device and a cutting line 230 installed on the upper side of the mounting base 210 for cutting the silicon core. Both sides of the cutting line 230 are guided and transmitted by a rolling shaft 220 movably installed on the upper end of the mounting base 210. The lower end of the cutting line 230 drives the cutting line 230 to move and cut through a wire roller. The wire roller of the cutting line 230 at the lower end has the same structure as the rolling shaft 220, and an adjustment unit 300 is also installed at the lower end for adjustment. The wire roller at the lower end is connected to the output end of the motor.

[0037] There are three groups of cutting lines 230, which are evenly arranged at the upper end of the mounting base 210. The size of the regular hexagonal silicon core to be cut is adjusted by the arrangement of the cutting lines 230. The three groups of cutting lines 230 form a regular hexagonal groove 231 and a regular triangle groove 232 for cutting the silicon core.

[0038] When the silicon core raw material needs to be cut, the silicon core raw material is fixed by the fixing claws and sent into the hole opened at the center of the mounting base 210. During the rising process, the cutting line 230 moving at the upper end continuously cuts the silicon core. The regular hexagonal grooves 231 and regular triangle grooves 232 formed in the middle of the three groups of cutting lines 230 can form regular hexagons and regular triangles in the cut silicon cores. Two types of silicon cores can be produced simultaneously, and the cutting is more convenient.

[0039] Furthermore, the rolling shaft 220 includes an installation shaft 240 for installation and support and a guide plate 221 mounted on the upper end of the installation shaft 240 for guiding the cutting line 230. The upper end of the guide plate 221 is provided with a guide groove 222 for limiting and fixing the cutting line 230. The cutting line 230 can be arranged in a circle inside the guide groove 222 of the guide plate 221 to avoid the cutting line 230 being misplaced during rotational cutting and affecting the normal cutting operation of the silicon core, thereby ensuring the normal transmission operation of the cutting line 230.

[0040] Furthermore, hexagonal fasteners 224 for fixing the guide disk 221 are installed on both sides of the guide disk 221, and a threaded portion is opened on the upper end of the installation shaft 240. The hexagonal fasteners 224 match the threaded portion on the upper end of the installation shaft 240. When it is necessary to adjust the size of the cut silicon core, the hexagonal fasteners 224 for fixing on both sides can be loosened, and then the guide disk 221 can be adjusted to a suitable position one by one, so as to facilitate the cutting of silicon cores of different sizes. The operation is simple and the adjustment is convenient. After adjustment, the hexagonal fasteners 224 can be used to clamp and fix it again.

[0041] The adjustment unit 300 includes a movable frame 310 that can be moved and fixed, and an installation box 330 movably installed at the lower end of the movable frame 310 for adjusting and moving the movable frame 310. The movable frame 310 is adjusted in spacing by a rotating rod 340 movably installed at the lower end. The middle part of the rotating rod 340 is sleeved on the upper end of a fixed pile 311 fixedly installed at the lower end of the movable frame 310. One end of the rotating rod 340 is installed on the inner edge of the installation box 330 through a traction rod 341 movably installed at one end. A threaded hole 312 is provided in the middle of the edge movable frame 310 for driving the movable frame 310 at the edge to move. A rotating screw 331 is movably installed on one side of the middle part of the installation box 330 for driving the movable frame 310 to move. The rotating screw 331 is threadedly connected to the threaded hole 312.

[0042] When the guide plate 221 needs to be adjusted, the rotating screw 331 installed inside the mobile frame 310 can be used to drive the mobile frame 310 to move. When the mobile frame 310 at the end moves, the rotating rod 340 movably installed at the lower end drives the adjacent mobile frame 310 to move synchronously, so that the upper mobile frame 310 can be adjusted to the same interval, and the lifted mobile frame 310 is close to the guide plate 221, so that the guide plate 221 installed at the upper end of the mobile frame 310 is pushed and moved. After moving, the guide plate 221 is fixed, which is convenient for the hexagonal fastener 224 to rotate, clamp and fix, and is convenient for processing.

[0043] Furthermore, a through hole 313 is formed at the upper end of the movable frame 310 on the other side of the rotating rod 340 for the rotating screw 331 to pass through. The diameter of the through hole 313 is larger than the diameter of the threaded hole 312. Limit rods are fixedly installed on both sides of the interior of the installation box 330, and the size of the limit holes formed at the upper end of the movable frame 310 are matched. During the movement of the movable frame 310, the limit rods support the movable frame 310 to avoid large wear on the through hole 313 and the rotating screw 331.

[0044] Furthermore, a driving device 332 for driving the rotating screw 331 to rotate is installed on one side of the lower end of the installation box 330. The driving device 332 is composed of a driving motor and a reducer, and the driving end is connected and driven to the end of the rotating screw 331 to facilitate driving the rotating screw 331 to rotate.

[0045] Furthermore, a lifting rod 333 is fixedly installed at the lower end of the installation box 330 for pushing the installation box 330 to rise. The lifting rod 333 is fixedly connected to the output end of the lifting cylinder. The lifting cylinder is installed inside the groove opened at the upper end of the installation base 210, which facilitates pushing the installation box 330 fixedly installed at the upper end of the lifting rod 333 to rise, and lifts the movable frame 310 to fix the guide plate 221, thereby facilitating the fixation of the guide plate 221.

[0046] Furthermore, a plug-in rod 320 for moving the position of the guide plate 221 is threadedly installed on the upper end of the movable frame 310. The plug-in rod 320 matches the size of the plug-in hole 223 evenly opened on the upper end of the guide plate 221. When the position of the guide plate 221 is fixedly adjusted, the plug-in rod 320 can be inserted into the inside of the guide plate 221, and then the guide plate 221 can be fixedly adjusted to avoid slipping and facilitate adjustment.

[0047] The working principle of a regular hexagonal silicon core cutting device is as follows: when the silicon core raw material needs to be cut, the silicon core raw material is fixed by a fixed claw and sent into the hole opened at the center of the mounting base 210. During the rising process, the cutting line 230 moving at the upper end continuously cuts the silicon core. The regular hexagonal groove 231 and the regular triangle groove 232 formed in the middle of the three groups of cutting lines 230 can form a regular hexagon and a regular triangle after cutting. Two types of silicon cores can be produced simultaneously, and cutting is more convenient.
