[0016] Beneficial effects of the present invention:

[0017] 1. The fine flake graphite powder particles in the discharge box of the present invention are transferred in equal amounts to the receiving seesaw on the processing disk through the discharge hole. The receiving seesaw limits the graphite powder particles and carries them to rotate in a circle. During the rotation of the receiving seesaw, it passes through a rolling assembly and a pushing assembly in sequence. The rolling assembly performs several roll-forming operations on the graphite powder particles on the receiving seesaw and flattens the receiving seesaw at the same time. After the rolling operation of the rolling assembly is completed, the pushing assembly pushes the flattened receiving seesaw upward to reset it and tilt it to cooperate with the discharge of large flake graphite. The above-mentioned arrangement realizes equal amount discharge and multiple rolling of graphite powder particles, so that the large flake graphite formed on the receiving seesaw has uniform shape and thickness, which solves the problem that the graphite forming in the prior art is too random and the formed large flake graphite has different shapes.

[0018] 2. A heating nozzle and a cooling nozzle are fixedly arranged on the rotating path of the processing disk of the present invention, and a matching through-hole is also arranged on the processing disk. The heating nozzle can fully preheat the graphite powder particles on the receiving seesaw plate stopped at the heating station through the arranged through-hole to cooperate with the subsequent multiple rolling. After the rolling is completed, the receiving seesaw plate stops at the cooling station and can completely cool the formed large flake graphite through the same principle to cooperate with the subsequent discharging, thereby ensuring the molten state required for the forming of the graphite powder particles and the cooling effect after forming, and improving the forming effect of the large flake graphite and the safety during discharging.

[0019] 3. The receiving seesaw of the present invention is used for limiting the position of graphite powder particles. When it comes into contact with the rolling assembly for the first time, the raised end of the receiving seesaw can fully resist the extrusion between the rolling cylinder through the reaction force of the return spring a before being flattened. The advantage of this design is that the graphite powder particles have a better rolling effect during the first rolling forming, and the graphite powder is squeezed more firmly. After the receiving seesaw is flattened, the subsequent rolling assembly can roll the large flake graphite formed once more smoothly, thereby improving the quality and effect of the large flake graphite after overall rolling forming.

[0020] In summary, the large-scale graphite pressing device has the advantages of ingenious design, simple structure, stable use, etc., and is particularly suitable for the field of graphite processing technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0032] Embodiment 1

[0034] Here, the fine flake graphite powder particles in the discharge box 2 of the present invention are transferred in equal amounts to the receiving seesaw 301 on the processing disk 3 through the discharge hole 102, and the receiving seesaw 301 limits the graphite powder particles and carries them to rotate in a circle. During the rotation of the receiving seesaw 301, it passes through the rolling component 4 and the pushing component 5 in sequence. The rolling component 4 performs several roll-forming on the graphite powder particles on the receiving seesaw 301 and flattens the receiving seesaw 301 at the same time. After the rolling component 4 completes the rolling, the pushing component 5 pushes the flattened receiving seesaw 301 upward to reset it and tilt it to cooperate with the discharge of large flake graphite. The above-mentioned arrangement realizes equal discharge of graphite powder particles and multiple rolling, so that the large flake graphite formed on the receiving seesaw 301 has a uniform shape and thickness, which solves the problem that the graphite forming in the prior art is too random and the formed large flake graphite has different shapes.

[0035] Refer to the attached Figure 1 and attached Figure 2 Specifically, a rotating motor 201 and a stirring blade 202 driven by the rotating motor 201 are fixedly arranged in the discharge box 2, and a baffle plate 203 matched with the discharge hole 102 is fixedly arranged directly below the discharge box 2 and between the turntable 101 and the processing disk 3. The rotating motor 201 drives the stirring blade 22 to continuously stir the fine flake graphite powder particles in the discharge box 2, which is conducive to the graphite powder particles falling into the discharge hole 102 quickly and smoothly. The baffle plate 203 can block the graphite powder particles in the discharge hole 102. When the turntable 101 rotates away from the baffle plate 203, the graphite powder particles in the discharge hole 102 fall into and are transferred to the corresponding receiving seesaw 301 on the processing disk 3. A plurality of groups of circular blocking ring blocks are equidistantly arranged on the processing disk 3, which can block and limit the receiving seesaw 301 between the two to prevent the graphite powder particles from dispersing.

[0036] Refer to the attached Figure 3 Specifically, the non-tilted end of the receiving seesaw 301 is fixedly connected to the processing disk 3, and a reset spring a302 is connected between the tilted end of the receiving seesaw 301 and the processing disk 3. The receiving seesaw 301 is made of a high-temperature resistant flexible material. The setting of the reset spring a302 can drive the tilted end of the receiving seesaw 301 to reset and tilt after being flattened by cooperating with the push assembly 5.

[0037] Refer to the attached Figure 3 and attached Figure 4 Specifically, a buckle block 303 is fixedly provided on the lower end surface of the tilted end of the receiving seesaw 301, and a buckle channel 304 cooperating with the buckle block 303 is also provided on the processing disk 3. The buckle block 303 is pressed by the rolling assembly 4 to squeeze the flexible blocking ring in the buckle channel 304 to deform it, so as to realize the locking buckle of the buckle block 303 and the buckle channel 304 (the state is as shown in FIG. Figure 4 shown).

[0038] Refer to the attached Figure 5 Specifically, the rolling assembly 4 includes a base 401 and a rotating base 402 arranged on the base 401, a rotating shaft 403 is rotatably arranged on the rotating base 402, and a plurality of rolling cylinders 404 that cooperate with the supporting seesaw 301 are fixedly connected to the rotating shaft 403, and the width of the rolling cylinder 404 cooperates with the width of the supporting seesaw 301.

[0039] Refer to the attached Figure 5 Specifically, a gear 405 is fixedly connected to the outer end of the rotating shaft 403, and an arc-shaped tooth row 406 meshing with the gear 405 is fixedly connected to the outer surface of the rotating disk 101. The arc-shaped tooth row 406 on the rotating disk 101 drives the gear 405 to rotate during rotation. The rotation of the gear 405 synchronously drives the rolling cylinder 404 set on the rotating seat 402 to rotate and cooperate with the passing receiving seesaw 301 to roll and extrude the graphite powder particles thereon. Grease is applied between the arc-shaped tooth row 406 and the gear 405, and between the rotating shaft 403 and the rotating seat 402 to reduce friction resistance during rotation.

[0040] Refer to the attached Figure 6 Specifically, the push assembly 5 includes a sliding sleeve 501 fixedly arranged on the lower end surface of the processing disk 3 and concentrically arranged with the buckle channel 304, a push rod 502 is slidably arranged in the sliding sleeve 501, a spring connecting block 503 is arranged on the push rod 502, and a return spring b504 is connected between the sliding sleeve 501 and the spring connecting block 503.

[0041] Refer to the attached Figure 7 Specifically, the lower end of the push rod 502 is also fixedly connected to a supporting ball 505, and a matching guide block 506 is fixedly arranged on the rotation path of the supporting ball 505, and the guide block 506 includes an ascending section 507, a pushing section 508 and a resetting section 509. The supporting ball 505 passes through the ascending section 507 of the guide block 506 during the rotation of the processing disk 3, and the ascending section 507 guides the push rod 502 to compress the resetting spring b504 and vertically rise in the sliding sleeve 501 to push the snap block 303 in the snap channel 304 upward and out of the snap channel 304, thereby realizing the resetting and tilting of the supporting seesaw 301. After passing through the resetting section 509, the supporting ball 505 drives the rising push rod to reset and retreat to the initial position under the self-restoring force of the resetting spring b504.

[0042] It should be noted that the receiving seesaw 301 of the present invention is used to limit the position of the graphite powder particles. When the receiving seesaw 301 first contacts the rolling assembly 4, the raised end of the receiving seesaw 301 is pressed flat by the reaction force of the return spring a302 (such as Fig. 9The advantage of this design is that the graphite powder particles have a better rolling effect during the first rolling forming, and the graphite powder is squeezed more firmly. After the seesaw 301 is flattened (as shown in the attached figure), it can fully resist the extrusion between the rolling cylinder 404. Figure 8 As shown in the figure), the subsequent rolling assembly 4 can roll the large flake graphite after the one-time forming more smoothly, thereby improving the quality and effect of the overall rolling forming of the large flake graphite.

[0043] Embodiment 2

[0044] As attached Figure 1 , Attachment Figure 2 and attached Figure 6 As shown, the components that are the same as or corresponding to those in the first embodiment are marked with the corresponding figure marks in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that a heating nozzle 6 and a cooling nozzle 7 are fixedly arranged below the rotation path of the processing disk 3, and a through opening 305 that cooperates with the heating nozzle 6 and the cooling nozzle 7 is also opened on the processing disk 3.

[0045] It is worth mentioning that a heating nozzle 6 and a cooling nozzle 7 are fixedly arranged on the rotation path of the processing disk 3 of the present invention, and a matching through hole 305 is also arranged on the processing disk 3. The heating nozzle 6 can fully preheat the graphite powder particles on the receiving seesaw 301 stopped at the heating station through the set through hole 305 to cooperate with the subsequent multiple rolling. After the rolling is completed, the receiving seesaw 301 stops at the cooling station and can completely cool the formed large flake graphite through the same principle to cooperate with the subsequent discharging, thereby ensuring the molten state required for the forming of the graphite powder particles and the cooling effect after forming, and improving the forming effect of the large flake graphite and the safety during discharging.

[0046] The working process of the present invention is as follows: the fine flake graphite powder particles in the discharge box 2 enter the corresponding discharge hole 102 of the lower turntable 101 under the stirring of the stirring blade 202. After the discharge hole 102 is filled, the turntable 101 starts to rotate. After the filled discharge hole 102 on the turntable 101 is separated from the baffle plate 203, the graphite powder particles fall into and are transferred to the corresponding receiving seesaws 301 on the processing disk 3. The receiving seesaws 301 receive and drive the graphite powder to continue to rotate. When it moves to the heating station, the turntable 101 stops rotating, and the heating nozzle 6 is aligned with the through port 305 to fully preheat the graphite powder particles on the receiving seesaws 301 to make them molten. Then the turntable 101 continues to rotate, and the receiving seesaws 301 pass through the first rolling assembly 4. The rollers on the rolling assembly 4 The pressing cylinder 404 performs a primary forming on the molten graphite powder on the receiving seesaw 301 and flattens the receiving seesaw 301. Then, the flattened receiving seesaw 301 passes through the second and third rolling assemblies during the rotation process, and the large flake graphite formed once is rolled multiple times. After the rolling is completed, the processing disk 3 rotates through the guide block 506. The support ball 505 of the pushing assembly 5, under the guidance of the rising section 507, drives the pushing rod 502 to push upward in the sliding sleeve 501, so that the flattened receiving seesaw 301 is reset and tilted. Then the processing disk 3 rotates to the cooling station, and the cooling nozzle 7 quickly cools the large flake graphite on the reset and tilted receiving seesaw 301. The operator clamps the cooled large flake graphite out through a clamp for collection, and the above process is repeated in sequence.
