[0030] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0031] Embodiment 1

[0032] like Figures 1 to 9 As shown, an embodiment of the present invention provides a flake graphite block manufacturing and forming device, including a servo motor 1 and a feed bin 2, the output end of the servo motor 1 is fixedly connected to a feed tray 3 and a forming tray 4, the feed tray 3 and the forming tray 4 are respectively provided with a feed hole 301 and a forming hole 401 which are concentrically matched, an extrusion plate 402 and a limit plate 403 connected to the extrusion plate 402 are arranged in the forming hole 401, the flake graphite particles in the feed bin 2 are transferred to the extrusion plate 402 through the feed hole 301, a shaking guide rail 5, a driving assembly 6 and an extrusion baffle 7 are sequentially arranged on the rotation path of the extrusion plate 402, the shaking guide rail 5 guides the extrusion plate 402 to shake up and down to shake the flake graphite particles accumulated on the extrusion plate 402 flat, the driving assembly 6 drives the extrusion plate 402 to rise and fall repeatedly to cooperate with the extrusion baffle 7 to extrude the flattened flake graphite particles in the forming hole 401.

[0033] Refer to the attached Figure 4 Specifically, the lower end surface of the extrusion plate 402 is fixedly connected with a lifting rod 404, the lower end surface of the forming disk 4 is provided with a sliding seat 405 matching the forming hole 401, the lifting rod 404 is slidably set on the sliding seat 405, the extrusion plate 402 and the forming disk 4 are made of high and low temperature resistant materials, the upper end surface of the extrusion plate 402 is rough, and the lower end surface of the extrusion baffle 7 is smooth.

[0034] Refer to the attached Figure 4 Specifically, a gear 406 and a supporting ball 407 are fixedly disposed on the lifting rod 404 in sequence.

[0035] Refer to the attached Figure 4 Specifically, the extrusion plate 402 and the limit plate 403 are threadedly connected. The limit plate 403 is arranged below the extrusion plate 402. A pair of limit rods 408 are fixedly arranged at the lower end of the limit plate 403. The limit rods 408 are slidably arranged on the sliding seat 405. The limit rods 408 can realize lifting and lowering in the vertical direction, but due to the limiting cooperation between the limit rods 408 and the sliding seat 405, circular rotation cannot be realized.

[0036] Refer to the attached Figure 4Specifically, a limit support block 409 and a spring connection block 410 are provided on the limit rod 408 , and a return spring 411 is connected between the spring connection block 410 and the sliding seat 405 .

[0037] Refer to the attached Figure 3 Specifically, the shaking guide rail 5 is a wavy guide rail that matches the rotation path of the support ball 407. The support ball 407 passes through the wavy guide rail during rotation, and the crest section of the wavy guide rail guides and drives the support ball 407 to rise. Since the extrusion plate 402 and the limit plate 403 are threadedly connected, the support ball 407 guides the extrusion plate 402 and the limit plate 403 to rise synchronously through the compression reset spring 411, and then returns to its original position through the trough section of the wavy guide rail through the self-restoring force of the spring, and achieves a shaking effect by moving up and down in sequence.

[0038] Here, the shaking guide rail 5 of the present invention is set as a wavy guide rail. During the rotation of the support ball 407, the wavy guide rail can drive the lifting rod 404 to reciprocate in the vertical direction on the sliding seat 405, and the flake graphite powder particles ( Figure 7 As shown) gradually shaken flat ( Figure 8 As shown in the figure, after heating, the flattened flake graphite powder particles can be combined with subsequent extrusion forming to make the formed flake graphite block uniform in thickness and consistent in strength at all locations, thereby improving the aesthetics and structural strength stability of the flake graphite block.

[0039] Refer to the attached Figure 5 Specifically, the driving assembly 6 includes a lifting rack 601, a downward rack 602, an ascending rack 603 and a discharging rack 604 which are fixedly arranged in sequence on the rotation path of the gear 406 and meshed with the gear 406. The lifting rack 601 is used to drive the gear 406 to rotate. Since the limiting cooperation between the limiting rod 408 and the sliding seat 405 cannot realize circular rotation, the limiting plate 403 is kept stationary while the extrusion plate 402 rises vertically. The heated flake graphite powder particles on the extrusion plate 402 first contact the extrusion baffle 7 for the first time to perform initial extrusion forming. Then the gear 406 drives the extrusion plate 402 and the initially formed flake graphite plate to move downward a short distance through the downward rack 602, and then performs subsequent multiple extrusion forming in the same way through the ascending rack 603. The discharging rack 604 is used to drive the formed flake graphite blocks on the extrusion plate 402 to continue to rise and separate from the forming hole 401 for subsequent discharging operations.

[0040] It should be pointed out that the extrusion plate 402 of the present invention is threadedly connected to the limiting plate 403, the limiting plate 403 is in a limiting state and cannot rotate, the driving assembly 6 drives the gear 406 to rotate through the rack, and the gear 406 rotates to realize the lifting and lowering of the extrusion plate 402 in the forming hole 401, and the rack includes a plurality of downward moving racks 602 and an upward rack 603. By repeatedly driving the lifting and lowering of the extrusion plate 402 on the rotation path, the heated flake graphite powder particles can be extruded and formed multiple times in cooperation with the fixed extrusion baffle 7 ( Fig. 9 As shown in the figure), multiple lifting and extrusion are beneficial to improving the pressing effect of flake graphite blocks, the product has high density, and the forming quality of flake graphite blocks is further improved.

[0041] Refer to the attached Figure 2 , Attachment Figure 3 and attached Figure 6 Specifically, one end of the material discharge bin 2 is fixedly connected to a support rod 201, and the support rod 201 is also fixedly connected to a material blocking baffle 202 arranged under the feed tray 3. A rotating motor 203 and a stirring blade 204 driven by the rotating motor 203 are also arranged in the material discharge bin 2. The material discharge bin 2 and the material blocking baffle 202 are both arranged in close contact with the clinker tray 3. After the material discharge hole 301 is filled with flake graphite powder particles and separated from the material blocking baffle 202, equal amounts of flake graphite powder particles fall into the extrusion plate 402 transferred to the forming hole 401 in turn. The rotating motor 203 drives the stirring blade 204 to rotate, which is beneficial to increasing the rate at which the flake graphite powder particles fall into the material discharge hole 301.

[0042] Refer to the attached Figure 2 and attached Figure 3 Specifically, a heating tube 8 and a cooling tube 9 are fixedly arranged between the feed tray 3 and the forming tray 4, and an extrusion baffle 7 is fixedly arranged between the heating tube 8 and the cooling tube 9 and is arranged in contact with the upper end surface of the forming tray 4. The feed tray 3 and the forming tray 4 rotate synchronously to the heating tube 8 and the cooling tube 9 and stop. The heating tube 8 is facing the forming hole 401 and can heat and melt the flake graphite powder particles inside to cooperate with subsequent extrusion forming. The cooling tube 9 can quickly cool the flake graphite blocks after extrusion forming to cooperate with subsequent discharging.

[0043] It is worth mentioning that the equipment of the present invention adopts a turntable structure to achieve the continuity of the pressing and forming operation. The turntable structure can make full use of the effective space of the production workshop and facilitate the assembly of the equipment. At the same time, multiple groups of feeding holes 301 and forming holes 401 can be opened on a single turntable structure to carry out multiple groups of production operations at the same time, which greatly improves the production efficiency of flake graphite blocks.

[0044] Embodiment 2

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 lies in that: a discharge guide plate 10 is fixedly connected to one side of the retaining baffle 202, and a discharge conveyor belt 1001 that cooperates with the discharge guide plate 10 is fixedly provided on the outer side of the forming disk 4. The flake graphite blocks after forming and cooling are separated from the forming hole 401 under the action of the discharge rack 604, and are contacted with the discharge guide plate 10 during the rotation and are output outward through the discharge conveyor belt 1001 in sequence.

[0046] The working process of the present invention is as follows: the flake graphite powder particles in the discharge bin 2 are input into the discharge hole 301, and a baffle plate 202 is arranged below the discharge bin 2 for baffle. After the discharge hole 301 rotates and disengages from the baffle plate 202, the flake graphite powder particles fall into the extrusion plate 402 transferred to the forming hole 401 and are piled up, and then pass through the flattening guide rail 5, and the piled flake graphite powder particles are shaken flat by repeated up and down shaking. After shaking flat, the feed disc 3 and the forming disc 4 stop above the heating tube 8, and the heating tube 8 heats the flattened flake graphite powder particles. After heating, the feed disc 3 and the forming disc 4 continue to rotate, and the extrusion plate 402 is driven to rise by the drive assembly 6 to cooperate with the extrusion baffle 7 to repeatedly extrude and form the heated flake graphite powder particles. After forming, it stops at the cooling tube 9 for cooling, and finally rotates through the discharge guide plate 10 to guide the flake graphite blocks to be transmitted outward through the discharge conveyor belt 1001, and the process is repeated in sequence.
