[0035] like Figure 1 - Figure 6 As shown, the present invention provides a multi-blade slicing device for gemstone raw materials, comprising a frame 7, a blade assembly, a drive assembly 8, and a moving assembly 9;

[0036] The cutter head assembly is horizontally disposed on the upper end of the frame 7 and is rotatably connected to the frame 7;

[0037] Drive component 8 is used to drive the cutter head assembly to rotate;

[0038] The movable component 9 is disposed on the side of the cutter head assembly and connected to the frame 7. A connecting arm 92 parallel to the cutter head assembly is connected to the movable component 9.

[0039] A mounting shaft 93 is detachably connected to the connecting arm 92;

[0040] The cutter head assembly includes a connecting shaft 1, a blade 2, a separator 3, and a fastening sleeve 4.

[0041] The blade 2 is ring-shaped and sleeved on the outer periphery of the connecting shaft 1, and several layers of blades 2 are arranged sequentially along the axial direction of the connecting shaft 1.

[0042] The separator 3 is ring-shaped and located between the two blades 2. The separator 3 and the blades 2 are alternately distributed on the connecting shaft 1.

[0043] This blade assembly is made of multiple stacked blades, which can replace the work of multiple single-blade cutting machines at one time, effectively improving cutting efficiency.

[0044] The fastening sleeve 4 has a through hole in the middle and a thread on its inner wall. The fastening sleeve 4 is threaded to the end of the connecting shaft 1. The blade 2 and the separator 3 are confined between the two fastening sleeves 4.

[0045] Among them, a separator 3 is provided between two adjacent blades 2. The thickness of the separator 3 can be flexibly changed or adjusted according to the requirements of the gemstone product to be processed, so as to change the spacing between the blades 2 and thus adapt to the requirements of different gemstone processing.

[0046] The separator 3 includes at least one pair of first separators 30 and second separators 31, and the first separators 30 and second separators 31 cooperate with each other through a limiting structure.

[0047] The separator 3 uses at least one pair of first separators 30 and second separators 31 that can cooperate with each other. The two separators that are in contact with each other are combined into a tight and non-slip integral separator 3 by a limiting structure.

[0048] like Figure 6 As shown, specifically, the limiting structure includes a groove 50 and a protrusion 51 conforming to the groove 50.

[0049] The groove 50 and the protrusion 51 can be simultaneously formed on one or both sides of the first partition 30 or the second partition 31. Alternatively, the groove 50 can be formed on one side of the first partition 30 and the second partition 31, while the protrusion 51 is formed on the other side. As long as the first partition 30 and the second partition 31 are in contact with each other, the groove 50 can cooperate with the corresponding protrusion 51, and the protrusion 51 extends into the groove 50.

[0050] In addition, a groove 50 and a protrusion 51 are provided on the same side of the same partition, and the radial distances from the two to the center are not equal, which can further increase the stability of the structure.

[0051] In addition, to increase the friction between the blade 2 and the separator 3, the surfaces of the first separator 30 and the second separator 31 can be processed into anti-slip textures to increase friction and prevent the blade 2 from sliding relative to each other during gem cutting, thereby affecting the cutting quality.

[0052] In addition, grooves 50 and / or protrusions 51 can be provided on the corresponding parts of the blade 2. This way, it can be connected with the separator 3 into a whole. While satisfying the function of controlling the spacing of the blade 2, it is not easy to slip during gemstone cutting, and the structure is more stable.

[0053] like Figure 3 As shown, a quick-release shaft 6 is coaxially connected to the outer side of the fastening sleeve 4. This assembly is connected to an external drive device and a transmission device via the quick-release shaft 6, and a bearing is sleeved on the outer periphery of the quick-release shaft 6. A connecting plate 60 is provided at the connection between the quick-release shaft 6 and the fastening sleeve 4, and a limiting protrusion 61 is provided at the end of the connecting plate 60.

[0054] The fastening sleeve 4 has at least one end face with several notches 40 along the circumferential direction, and the limiting protrusion 61 cooperates with the notches 40.

[0055] This component uses a notch 40 on the fastening sleeve 4, and a limiting ridge 61 that matches the quick-release shaft 6 is provided at the end of the shaft. Based on the basic power transmission structure, the purpose of quickly installing this cutter head assembly can be achieved.

[0056] Furthermore, when it is necessary to assemble or disassemble each blade 2 and the separator 3, the fastening sleeve 4 is tightened in both directions using tools such as pliers and wrenches. Therefore, the outer contour of the cross-section of the fastening sleeve 4 is a polygon, and the specific form of the polygon is not specifically limited; it can be a regular hexagon, a regular pentagon, etc.

[0057] The moving component 9 in this embodiment can adopt various structural forms, such as telescopic cylinders, screw mechanisms, etc. When a screw mechanism is used, a motor is used as a power source to make the screw mechanism run, driving the slider 91 to move on the slide rail 90, wherein the connecting arm 92 is connected to the slider 91.

[0058] Of course, the moving component 9 controls the movement direction of the slider 91, which can be horizontal or vertical, adjusting the distance between the gemstone material adhered to the mounting shaft 93 and the cutter head assembly, thereby achieving the purpose of multi-piece cutting of the gemstone material.

[0059] The aforementioned mounting shaft 93 is threadedly connected to the connecting arm 92. The raw material to be sliced ​​is pre-attached to the outer wall of the mounting shaft 93 using adhesive, achieving rapid installation and fixation of the raw material through the threads.

[0060] The bottom of the frame 7 is equipped with support legs 70, on which casters are installed, which can facilitate the movement of the entire device and reduce transportation costs.

[0061] A spray assembly (not shown in the diagram) that acts on the cutter head assembly is also connected to the frame 7. When cutting gemstone raw materials, the spray assembly provides water to the cutter head assembly and the raw materials to cool them down and prevent powder from spreading.

[0062] In addition, a liquid receiving guide plate 71 is provided at the bottom of the cutter head assembly. The liquid receiving guide plate 71 is used to guide the water sprayed from the top to the collection bucket for centralized collection and treatment.

[0063] It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
