[0036] The heating mechanism 3 includes an insulating barrel 31 and a heater body 33. The inner wall of the insulating barrel 31 is fixedly connected to the outer wall of the barrel body 4. The inner wall of the insulating barrel 31 is embedded with a heating plate 34, and the outer wall of the barrel body 4 is matched with the inner side of the heating plate 34. The top of the heater body 33 is electrically connected to the bottom of the heating plate 34. The bottom of the heating plate 34 is provided with a heat dissipation port 32, and the heat dissipation port 32 is provided at the bottom of the insulating barrel 31.

[0037] like Figure 3-Figure 5 and Figure 9 As shown, the sealing cover mechanism 5 includes two sleeves 51, and the two sleeves 51 are internally rotatably connected with two pairs of symmetrically installed half covers 52. The right sides of the two half covers 52 are jointly provided with a locking assembly 53, and the bottoms of the inner walls of the two half covers 52 are fixedly sleeved with large half sealing rings 54, and the inner sides of the large half sealing rings 54 cooperate with the top of the outer wall of the barrel body 4.

[0038] The design of two half covers 52 is adopted so that the two half covers 52 can be rotated and unfolded around the sleeve 51 as the axis, making it convenient to take and place the carbon rod 7;

[0039] The large sealing ring 54 is mainly used to seal the connection between the half cover 52 and the barrel body 4.

[0040] like Figure 4 、 Figure 5 and Figure 9 As shown, a sealing strip 55 is fixedly installed on one of the two half covers 52 on the adjacent side, and a small sealing ring 56 is fixedly installed on the axis of the other half cover, and the inner sides of the sealing strip 55 and the small sealing ring 56 form a circular ring.

[0041] By cooperating with the sealing strip 55 and the small sealing ring 56, the connection between the two half covers 52 can be sealed, and a certain sealing can be achieved between the output end of the reduction motor 61 and the two half covers 52, thereby improving the airtightness of the device.

[0042] like Figure 3 and Figure 10 As shown, the locking assembly 53 includes a U-shaped rotating block 531 and a U-shaped block 533, which is located on the right side of the front half cover 52 and fixedly installed on the left side of the U-shaped rotating block 531, and is located on the right side of the rear half cover 52 and fixedly installed on the left side of the U-shaped block 533.

[0043] When locking the two half covers 52, the T-screw 532 is rotated clockwise so that the T-screw 532 lies in the inner cavity of the U-shaped block 533, and the adjusting screw sleeve 534 cannot be rotated. The adjusting screw sleeve 534 is inserted into the rear side of the U-shaped block 533 under the action of the threaded connection with the T-screw 532, and the locking between the two half covers 52 can be achieved.

[0044] like Figure 1 、 Figure 5-Figure 8 As shown, the carbon rod placement assembly 6 includes a reduction motor 61, the bottom of the reduction motor 61 is fixedly mounted on the right side of the upper surface of the mounting frame 25, the output end of the reduction motor 61 passes through the mounting frame 25 and is fixedly mounted with a hexagonal shaft 62, the bottom of the hexagonal shaft 62 is rotatably connected to the shaft 66, a honeycomb cylinder 63 is fixedly mounted in the middle of the outer wall of the shaft 66, a tray 64 is fixedly mounted on the bottom of the shaft 66, and a plurality of positioning rings 65 distributed in a ring are fixedly mounted on the bottom of the inner wall of the tray 64, the carbon rod 7 is placed on the inner side of the honeycomb cylinder 63 and the positioning ring 65, and a base 67 is fixedly mounted on the bottom of the inner cavity of the barrel body 4.

[0045] The honeycomb cylinder 63 and the tray 64 can be driven by the reduction motor 61 to rotate the placed carbon rods 7 so that the carbon rods 7 are heated more evenly in the inner cavity of the barrel 4, thereby improving the production effect of the carbon rods 7.

[0046] like Figure 6 As shown, a disc 68 is inserted into the top of the base 67, and the top of the disc 68 is rotatably connected to the middle of the lower surface of the tray 64. An annular groove 69 is provided at the edge of the upper surface of the disc 68. The inner wall of the annular groove 69 is slidably connected to a plurality of balls 610 distributed in a ring shape, and the top of the outer wall of the ball 610 is slidably connected to the bottom of the tray 64.

[0047] The cooperation between the annular groove 69 and the ball bearing 610 is adopted so that the inserting plate 68 and the tray 64 can rotate while having a certain supporting effect, so that the base 67 can support the inserting plate 68.

[0048] like Figure 8 As shown, the outer wall of the hexagonal shaft 62 is movably sleeved with a hexagonal cylinder 612 , and the bottom of the outer wall of the hexagonal cylinder 612 is matched with the middle of the top of the honeycomb cylinder 63 .

[0049] The hexagonal cylinder 612 is used to connect the hexagonal shaft 62 and the honeycomb cylinder 63 , so that the honeycomb cylinder 63 can be rotated by the rotation of the hexagonal shaft 62 by the reduction motor 61 .

[0050] like Figure 8As shown, a spring push plate 613 is placed on the inner side of the hexagonal tube 612, and a positioning bead 614 is movably connected to one end of the spring push plate 613 close to the axis of the hexagonal tube 612. Positioning grooves 611 are opened at the upper and lower positions of the outer wall of the hexagonal shaft 62, and the inner wall of the positioning groove 611 cooperates with the outer wall of the positioning bead 614.

[0051] The spring push plate 613 pushes the positioning bead 614 so that the positioning bead 614 can be matched with one of the positioning grooves 611 as needed, so as to control the position of the hexagonal tube 612.

[0052] The working principle of the present invention is as follows: when in use, the carbon rod 7 is placed in the inner cavity of the honeycomb cylinder 63, so that the bottom of the carbon rod 7 is located on the inner side of the positioning ring 65, and then the hexagonal cylinder 612 is pushed downward to separate the outer wall of the positioning bead 614 from the positioning groove 611 at the top, and the bottom of the outer wall of the hexagonal cylinder 612 is inserted into the middle of the honeycomb cylinder 63, so that the outer wall of the positioning bead 614 is matched with the positioning groove 611 at the bottom to realize the connection between the hexagonal axis 62 and the honeycomb cylinder 63, and then the motor 24 can drive the stud 23 to rotate, and the sliding sleeve 22 can be moved downward to a certain extent, so that the honeycomb cylinder 63 with the carbon rod 7 and The tray 64 must be inserted into the inner cavity of the barrel body 4, and the bottom of the outer wall of the inserting plate 68 is inserted into the top of the base 67. Then, the two half covers 52 are rotated to dock the two half covers 52. Under the action of the locking assembly 53, the two half covers 52 are locked, and the reduction motor 61 and the heater body 33 can be started. The reduction motor 61 mainly drives the honeycomb cylinder 63 and the tray 64 to rotate, so that the carbon rods 7 are evenly heated in the inner cavity of the barrel body 4. The heater body 33 heats the outer wall of the barrel body 4 under the action of the heating plate 34, thereby heating the interior of the barrel body 4 for heating the carbon rods 7 in production.

[0053] The design of the hexagonal cylinder 612 is adopted. Since the present application adopts a reduction motor with a self-locking function, the hexagonal shaft 62 cannot be rotated in the non-starting state, thereby affecting the loading and unloading of the carbon rod 7;

[0054] The main innovation direction of this application is the mechanical mechanism itself, and the related technologies such as circuit control and temperature monitoring are all existing technologies, so this application does not need to describe them in detail.

[0055] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
