Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0023] In order to further understand the content of the present application, the present application will be described in detail with reference to the drawings.

[0024] In combination with Figs. 1-2 A kind of artificial graphite coating modification device, including cylinder 1, support leg 11 being fixedly connected at the bottom end of cylinder 1, cylinder cover 2 being arranged at the top end of cylinder 1, and heating assembly 3 being arranged on the outer surface of cylinder 1, cylinder cover 2 outer surface is provided with stirring adjustment assembly 4, and inner gear 5 is arranged below cylinder cover 2.

[0025] The present application will be further described below in combination with embodiments.

[0026] Please refer to Figs. 1-5The stirring adjusting assembly 4 comprises a support plate 41 fixedly connected to the top end of the barrel cover 2, a first motor 42 fixedly connected to one side of the support plate 41, a first rotating shaft 43 fixedly connected to the output end of the first motor 42, a half gear 44 fixedly connected to one end of the first rotating shaft 43, a first connecting plate 411 and a second connecting plate 412 fixedly connected to one side of the support plate 41, a connecting column 45 rotatably connected to the bottom end of the first connecting plate 411, a first gear 46 and a second gear 47 fixedly connected to the outer surface of the connecting column 45, a connecting shaft 49 fixedly connected to the bottom end of the connecting column 45, a first rotating rod 48 fixedly connected to the bottom end of the connecting shaft 49, and stirring blades 410 fixedly connected to the outer surface of the first rotating rod 48. The first gear 46 is in meshing connection with the half gear 44, the second gear 47 is in meshing connection with the half gear 44, the connecting column 45 is rotatably penetrated through the second connecting plate 412, and the connecting shaft 49 is rotatably penetrated through the barrel cover 2. The first motor 42 drives the first rotating shaft 43 to rotate, the first rotating shaft 43 drives the half gear 44 to rotate, the tooth block of the half gear 44 is rotated to the first gear 46, and when the tooth block is in meshing connection with the first gear 46, the first gear 46 and the connecting column 45 are driven to rotate, so that the connecting shaft 49 and the stirring blades 410 are driven to rotate, thereby facilitating the mixing of materials. When the tooth block of the half gear 44 is away from the first gear 46 and is in meshing connection with the second gear 47, the second gear 47 drives the connecting column 45 to rotate in the opposite direction, so that the connecting shaft 49 and the stirring blades 410 are driven to rotate in the opposite direction, thereby facilitating the adjustment of the rotating direction of the stirring blades 410. The first motor 42 drives the half gear 44 to alternately mesh with the first gear 46 and the second gear 47, so that the connecting column 45 and the stirring blades 410 below are switched in the rotating direction between the forward direction and the reverse direction. Through bidirectional stirring, the material agglomeration is more effectively broken, the dead angle is avoided, and the material is more uniformly dispersed in the barrel 1.

[0027] The barrel 1 is internally provided with a mixing assembly 6. The mixing assembly 6 comprises a first connecting rod 61 fixedly connected to the outer surface of the connecting shaft 49, a second connecting rod 62 fixedly connected to one end of the first connecting rod 61, a third gear 63 fixedly connected to the bottom end of the second connecting rod 62, a second rotating rod 64 fixedly connected to the bottom end of the third gear 63, a heating wire arranged in the second rotating rod 64, a connecting sleeve 65 arranged on the outer surface of the second rotating rod 64, and a stirring rod 66 fixedly connected to the outer surface of the connecting sleeve 65. The third gear 63 is in meshing connection with the internal gear 5. The rotating of the connecting shaft 49 drives the first connecting rod 61 and the second connecting rod 62 to rotate, thereby driving the third gear 63 to rotate along the internal gear 5, further driving the stirring rod 66 to rotate, thereby facilitating the expansion of the stirring range. The heating wire is arranged in the second rotating rod 64, and the rotation thereof facilitates the more extensive transmission of heat, which is helpful to improve the temperature consistency of the materials in the entire barrel 1.

[0028] The outer surface of the connecting sleeve 65 is fixedly connected with a scraper 651, which is in contact with the inner wall of the cylinder 1. The third gear 63 rotates along the inner gear 5 to drive the scraper 651 to rotate along the inner wall of the cylinder 1, thereby reducing the adhesion of the inner wall of the cylinder 1.

[0029] The heating assembly 3 comprises a heating box 31 fixedly connected to the outer surface of the cylinder 1, a second motor 32 fixedly connected to one side of the heating box 31, a second rotating shaft 33 fixedly connected to the output end of the second motor 32, an auxiliary fan 34 fixedly connected to one end of the second rotating shaft 33, a heating rod 35 arranged inside the heating box 31, and a transmission pipe 36 arranged between the heating box 31 and the cylinder cover 2. The heating rod 35 is arranged above the auxiliary fan 34, and the second rotating shaft 33 penetrates through the heating box 31. The second motor 32 drives the second rotating shaft 33 and the auxiliary fan 34 to rotate. At this time, the airflow passing through the heating rod 35 in a heated state is heated and warmed. The warmed airflow enters the cylinder 1 through the transmission pipe 36, thereby facilitating the heating treatment of the materials in the cylinder 1.

[0030] The bottom end of the cylinder cover 2 is fixedly connected with a support block 21, which is fixedly connected with the inner gear 5. The support block 21 provides firm support, so that the inner gear 5 maintains its axial and radial positions unchanged, thereby ensuring the precise meshing between the inner gear 5 and the third gear 63.

[0031] The outer surface of the cylinder 1 is provided with a feeding pipe 12 and a discharging pipe 13, and the outer surface of the discharging pipe 13 is provided with a valve 131. The feeding pipe 12 facilitates feeding, and the opening of the valve 131 facilitates discharging.

[0032] In use, the second motor 32 drives the auxiliary fan 34 to rotate. At this time, the airflow passing through the heating rod 35 in a heated state is heated and warmed. The warmed airflow enters the cylinder 1 for heating through the transmission pipe 36. The first motor 42 drives the half gear 44 to rotate. When the tooth block of the half gear 44 rotates to the first gear 46 and is meshingly connected with the first gear 46, the first gear 46 and the connecting column 45 are driven to rotate, thereby driving the stirring blade 410 to rotate, facilitating mixing. When the tooth block of the half gear 44 moves away from the first gear 46 and is meshingly connected with the second gear 47, the second gear 47 drives the connecting column 45 to rotate in the opposite direction, thereby driving the connecting shaft 49 and the stirring blade 410 to rotate in the opposite direction, thereby facilitating the adjustment of the rotating direction of the stirring blade 410. Through bidirectional stirring, the material aggregation is more effectively broken, and the formation of dead angles is avoided, so that the material is more uniformly dispersed in the cylinder 1. The rotating of the connecting shaft 49 drives the first connecting rod 61 and the second connecting rod 62 to rotate, thereby driving the third gear 63 to rotate along the inner gear 5, further driving the stirring rod 66 to rotate, thereby expanding the stirring range, and driving the scraper 651 to rotate along the inner wall of the cylinder 1, thereby reducing the adhesion of the inner wall of the cylinder 1.
