[0032] The following will be combined with the Figures 1 to 11 The technical solutions of the present invention are clearly and completely described. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] The present invention provides a graphite green embryo baking furnace through improvement. Figures 1-11As shown, it includes a workbench 1 and a roasting furnace 2. The workbench 1 is provided with multiple groups of penetrating sliding cavities 101. A symmetrical slide 102 is provided on the inner wall of the sliding cavity 101. The bottom of the workbench 1 is provided with an outer rotating cavity 103 and an inner rotating cavity 104 that penetrates the slide 102. The outer rotating cavity 103 is located at the edge of the sliding cavity 101, and the inner rotating cavity 104 is symmetrically arranged on both sides of the middle of the sliding cavity 101; a blanking plate 106 is slidingly provided in the sliding cavity 101, and the blanking plate 106 consists of a convex plate 107 and a T-stage 109. Tooth plates 110 are provided on both sides of the T-stage 109; a linkage gear 111 meshing with the tooth plate 110 is provided for rotation in the outer rotating cavity 103, and a linkage gear 111 meshing with the tooth plate 110 is provided for rotation in the inner rotating cavity 104. A lifting gear 116 meshing with the tooth plate 110 is rotatably provided, a through hole 115 penetrating the workbench 1 is provided at the top of the inner rotating chamber 104, and a threaded rod 117 penetrating the through hole 115 is fixedly provided on the top of the lifting gear 116; the roasting furnace 2 is fixedly provided in the middle of the workbench 1, and a plurality of feeding chambers 201 are provided on the outer wall of the roasting furnace 2, and a feeding channel 202 cooperating with the blanking plate 106 is fixedly provided on the outer side of the feeding chamber 201, and a door panel 203 is slidingly provided on the side of the feeding channel 202, and threaded seats 204 cooperating with the threaded rod 117 are fixedly provided on both sides of the door panel 203; a gear ring 112 is also rotatably provided at the bottom of the workbench 1, and the gear ring 112 is meshed with each group of linkage gears 111.

[0034] In this embodiment, the graphite green sheet roasting furnace is primarily composed of two parts: a workbench 1 and a roasting furnace 2. To use the equipment, the motor 122 is first activated via the control panel 105. When the motor 122, via the drive gear 123, drives the ring gear 112 counterclockwise, the linkage gear 111 drives the multiple sets of blanking plates 106 outward. As the blanking plates 106 slide outward along the sliding cavity 101, the lifting gear 116 on the right side of the blanking plates 106 drives the threaded rod 117 on top clockwise, while the lifting gear 116 on the left side of the blanking plates 106 drives the threaded rod 117 on top counterclockwise. At this point, the door panel 203 opens upward along the feed channel 202. A worker then places the graphite green sheet onto the blanking plates 106. As the drive gear 123 drives the ring gear 112 clockwise, the blanking plates 106 slide inward along the sliding cavity 101. At this time, the lifting gear 116 located on the right side of the blanking plate 106 will drive the top threaded rod 117 to rotate counterclockwise, and the lifting gear 116 located on the left side of the blanking plate 106 will drive the top threaded rod 117 to rotate clockwise, and the door panel 203 will close downward along the feed channel 202.

[0035] See attached Figure 2 -Attached Figure 3 and attached Figure 11A mounting groove 119 is provided at the top of the inner rotating chamber 104 , and a mounting rail 118 is fixedly provided at the top of the lifting gear 116 , and the lifting gear 116 is rotatably set in the inner rotating chamber 104 through the mounting rail 118 .

[0036] In this embodiment, in order to make the lifting gear 116 drive the threaded rod 117 at the top to rotate, the lifting gear 116 is rotatably arranged in the inner rotating cavity 104 through the mounting rail 118. The threaded rod 117 is located at the center position of the annular mounting rail 118.

[0037] See attached Figure 2 -Attached Figure 3 and attached Figure 8 The convex plate 107 is provided with a slot 108 that cooperates with the lifting gear 116.

[0038] In this embodiment: when the lifting gear 116 rotates and the blanking plate 106 reciprocates, in order to avoid interference from the protruding plate 107 on the blanking plate 106, a slot 108 structure is designed, and the depth of the slot 108 is the same as the depth of the mounting slot 119.

[0039] See attached Figure 1 and attached Figure 8 A pressure relief valve 205 is also provided on the top of the roasting furnace 2, and a limit ring 208 is provided on the top of the pressure relief valve 205. A plurality of groups of protruding arms 209 are provided on the inner wall of the pressure relief valve 205, and a reset spring 210 is connected to the top of the reset spring 210. A moving block 211 is connected to the top of the reset spring 210; a plurality of groups of exhaust holes 212 are provided on the edge of the moving block 211, and a horizontal plate 213 is provided between the protruding arms 209. A cylinder 214 cooperating with the moving block 211 is installed in the middle of the horizontal plate 213, and a sensor 215 is also installed at the bottom of one group of protruding arms 209.

[0040] In this embodiment, during the roasting process, inert gas is injected into the roasting furnace 2 via the inflator 206. This gas expands and the pressure inside the roasting furnace 2 increases. To prevent excessive pressure from affecting the roasting effect, a pressure relief valve 205 is provided at the top of the roasting furnace 2. When the sensor 215 detects that the pressure has reached a critical value, it closes the cylinder 214, causing the output end of the cylinder 214 to retract outward. The gas inside the roasting furnace 2 impacts the moving block 211 outward. Under the impact of the airflow, the moving block 211 moves outward, causing the exhaust hole 212 to disengage the retaining ring 208, allowing the gas to escape through the exhaust hole 212. As the airflow weakens, the moving block 211 gradually moves inward under the action of the return spring 210. When the sensor 215 detects that the airflow intensity has weakened to a preset value, it activates the cylinder 214, which then returns the moving block 211 to its original position and abuts against its bottom. When the roasting is completed, the fan 124 will inflate the roasting furnace 2 and cool it down. At this time, the cylinder 214 will start again and release the pressure through the exhaust hole 212.

[0041] See attached Figure 2 and attached Figure 5 A plurality of support legs 120 are provided at the bottom of the workbench 1, wherein a mounting boss 121 is provided on the inner side of one set of support legs 120, a motor 122 is installed on the top of the mounting boss 121, and an output end of the motor 122 is connected to a driving gear 123 meshing with the ring gear 112.

[0042] In this embodiment, in order to automatically drive the ring gear 112 to rotate, thereby realizing the loading and unloading of graphite, the output end of the motor 122 is connected to a driving gear 123 that meshes with the ring gear 112 .

[0043] See attached Figure 9 -Attached Figure 10 , opposite threads are provided on the threaded rods 117 on both sides of the sliding cavity 101.

[0044] In this embodiment, in order to ensure synchronous drive of the threaded seat 204, opposite threads are designed. When the lower plate 106 slides outward along the sliding cavity 101, the lifting gear 116 on the right side of the lower plate 106 drives the top threaded rod 117 to rotate clockwise, and the lifting gear 116 on the left side of the lower plate 106 drives the top threaded rod 117 to rotate counterclockwise, at which point the door panel 203 opens upward along the feed channel 202. When the lower plate 106 slides inward along the sliding cavity 101, the lifting gear 116 on the right side of the lower plate 106 drives the top threaded rod 117 to rotate counterclockwise, and the lifting gear 116 on the left side of the lower plate 106 drives the top threaded rod 117 to rotate clockwise, at which point the door panel 203 closes downward along the feed channel 202.

[0045] See attached Figure 5 -Attached Figure 6 and attached Figure 10 The bottom of the workbench 1 is provided with multiple groups of T-shaped rails 113, and the top of the gear ring 112 is provided with a T-shaped slot 114 that matches it.

[0046] In this embodiment, in order to install the gear ring 112 and rotate it relative to the bottom of the workbench 1, a T-rail 113 and a T-slot 114 structure that cooperate with each other are designed.

[0047] See attached Figure 5 -Attached Figure 6 A fan 124 is provided at the bottom of the workbench 1 , and an output end of the fan 124 is connected to an air duct 125 provided inside the roasting furnace 2 .

[0048] In this embodiment, after the roasting is completed, in order to quickly cool down the graphite, the air duct 125 is set inside the roasting furnace 2.

[0049] See attached Figure 1 An aeration device 206 is also installed on the workbench 1, and the aeration device 206 is connected to the interior of the roasting furnace 2 through an aeration pipe 207.

[0050] In this embodiment, in order to inject inert gas into the roasting furnace 2 and thus improve the roasting effect, an inflation device 206 is installed on the workbench 1.

[0051] See attached Figure 1 -Attached Figure 2 A control panel 105 is also provided on one set of support legs 120 .

[0052] In this embodiment, a control panel 105 is designed to control the overall operation of the device.

[0053] The operating principle of the present invention is as follows: To use the device, the motor 122 is first activated via the control panel 105. When the motor 122 drives the ring gear 112 counterclockwise via the drive gear 123, the multiple sets of blanking plates 106 are driven outward by the linkage gear 111. As the blanking plates 106 slide outward along the sliding cavity 101, the lifting gear 116 on the right side of the blanking plates 106 drives the threaded rod 117 on top to rotate clockwise, while the lifting gear 116 on the left side of the blanking plates 106 drives the threaded rod 117 on top to rotate counterclockwise. At this point, the door panel 203 opens upward along the feed channel 202. The operator then places the graphite blank onto the blanking plates 106. As the drive gear 123 drives the ring gear 112 clockwise, the blanking plates 106 slide inward along the sliding cavity 101. At this time, the lifting gear 116 located on the right side of the blanking plate 106 will drive the top threaded rod 117 to rotate counterclockwise, and the lifting gear 116 located on the left side of the blanking plate 106 will drive the top threaded rod 117 to rotate clockwise, and the door panel 203 will close downward along the feed channel 202.
