[0002] The prior art adopts the processing technology that a plurality of shaping machines are connected in series in the traditional natural graphite shaping technology. The material preliminarily shaped by the previous stage shaping machine enters the next stage shaping machine for further shaping. Generally, the shaping system is composed of three to five groups of shaping machines connected in series. Moreover, the internal rotary hammer head of the existing graphite shaping equipment is a rigid hammer head made of metal or ceramic. The hammer head is in contact with the graphite to polish the edges and corners of the graphite, so as to remove the excess edges and corners of the graphite and achieve the purpose of shaping.

[0003] However, when the rigid hammer head of the graphite shaping machine of the prior art is in contact with the graphite and performs polishing, the rigid hammer head is prone to cause the graphite particles to be broken and generate useless fine powder waste. Moreover, the multi-stage shaping of the graphite shaping system of the prior art also causes the graphite particles to be broken in multiple stages, thereby generating more fine powder waste, resulting in a low yield of finished products.

[0026] In view of the deficiencies in the prior art, the present inventors have long studied and practiced a lot to come up with the technical solutions of the present application. The technical solutions, implementation process and principles will be further explained as follows.

[0027] Figs. 1-3 As shown is a graphite shaping equipment according to an embodiment of the present application, which comprises a cylinder 1 and a rotating main disc 3, wherein the cylinder 1 has a shaping cavity 2 inside, the shaping cavity 2 has graphite particles to be processed inside, the rotating main disc 3 is rotationally arranged in the shaping cavity 2, and the rotating main disc 3 is provided with a plurality of turntable cutter head groups 4, the surface layer of the turntable cutter head group 4 is made of high-hardness polyurethane, the turntable cutter head group 4 strikes the graphite particles in the process of rotation, due to the elasticity of the turntable cutter head group 4, the turntable cutter head group 4 will produce a hitting buffer to the graphite particles, and then bounce out without breaking the graphite particles, at the same time, due to the elasticity, the turntable cutter head group 4 imparts greater kinetic energy to the graphite particles, and finally bounces the graphite particles to the inner wall of the shaping cavity 2, so that the graphite particles rub against the inner wall of the shaping cavity 2 with extremely high kinetic energy, and at this point, less micro-powder waste will be generated, and at the same time, strong friction will also be generated between the graphite particles inside the shaping cavity 2, finally removing the excess edges and corners of the graphite particles, so that the graphite particles become spherical, and the purpose of graphite shaping is achieved.

[0028] In addition, as Fig. 3As shown, there is a gap between two adjacent cutter heads arranged in the radial direction, which has two effects, one is to increase the hitting probability of two cutter heads than one cutter head, and the other is to form a horn-shaped gap with narrow middle and wide both sides between two cutter heads, which is beneficial to the extrusion and friction of the material and the spheroidization of graphite particles.

[0029] It should be noted that the diameter of the graphite particles is about 15 microns, and when the tap density of the existing shaping equipment reaches 1t / m 3 , the yield of the finished product of the existing shaping equipment is about 50%; using the graphite shaping equipment of the embodiment, for the same particle size of graphite, the tap density of 1t / m 3 is also used, and the yield of the finished product can reach 90%; the reason is that when the graphite particles and the inner wall of the shaping cavity 2 contact and rub, the contact area is larger, so the friction of the graphite on the inner wall of the shaping cavity 2 is more slight than the existing prior art, and the graphite particles are broken, so the micro-powder waste generated by the breakage of the inner wall of the shaping cavity 2 is less than the micro-powder waste generated by the breakage of the graphite particles in the prior art, thereby greatly reducing the generation of micro-powder waste; the cylinder 1 is also provided with a top cover 11, and the top cover 11 and the shaping cavity 2 form a closed space, when the graphite particles are shaped in the shaping cavity 2, the top cover 11 is used to prevent the micro-powder waste generated by the friction between the graphite particles and the inner wall of the shaping cavity 2, or the micro-powder generated by the friction between the graphite particles from spilling out of the shaping cavity 2, thereby ensuring the cleanliness of the equipment after shaping.

[0030] The rotating disc cutter head group 4 is uniformly distributed along the circumference of the end surface of the rotating main disc 3, the rotating disc cutter head group 4 includes a plurality of rotating disc cutter heads 5, the rotating disc cutter head 5 and the rotating main disc 3 are connected by a cutter head base 6, the function of the cutter head base 6 is to increase the rotation range of the rotating disc cutter head 5, the rotating disc cutter head 5 is columnar and the axis of the rotating disc cutter head 5 is perpendicular to the end surface of the rotating main disc 3, the rotating disc cutter head 5 is distributed along the radial direction of the rotating main disc 3, the height of the rotating disc cutter head 5 gradually decreases from outside to inside along the radial direction of the rotating main disc 3, that is, when the rotating main disc 3 drives the rotating disc cutter head group 4 to rotate, the rotating disc cutter head 5 will form a path similar to a ring due to rotation, and the upper end of the ring-shaped path also has an inclined angle, which better matches the movement trajectory of the graphite particles in the cylinder 1, and the rotating disc cutter head 5 close to the axis of the rotating main disc 3 is shorter in length, which also realizes the lightweight of the overall shaping equipment.

[0031] The graphite shaping device further comprises a motor 7 and a main shaft 8 fixedly arranged on the rotating main disc 3, and the specific connection mode comprises but is not limited to a key connection, any mode capable of fixedly connecting the main shaft 8 and the rotating main disc 3 in the circumferential direction is within the protection scope of the utility model, the driving shaft of the motor 7 and the main shaft 8 are both provided with a transmission belt wheel 9, a transmission belt 10 is connected between the two transmission belt wheels 9, the transmission belt 10 transmits the torque of the driving shaft of the motor 7 to the main shaft 8, and the rotating main disc 3 is driven to rotate by the main shaft 8, so that the rotating disc cutter head group 4 is driven to rotate and the graphite particles are hit and then rebounded to the inner wall of the shaping cavity 2 for shaping.

[0032] It should be understood that the above embodiments are only for illustrating the technical concept and characteristics of the utility model, and its purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and it cannot limit the protection scope of the utility model.
