[0032] Specifically, the third heating plate 14 and the fourth heating plate 15 are respectively placed in the third heat preservation cover 12 and the fourth heat preservation cover 13, and the third heating plate 14 and the fourth heating plate 15 are electrically connected to the external power supply, the third heat preservation cover 12 and the fourth heat preservation cover 13 are sleeved outside the feed pipe 8 and the discharge pipe 9, and the through holes 21 on the third heat preservation cover 12 and the fourth heat preservation cover 13 are matched with the bearing 22 outside the rotating shaft 10, and the third limit plate 25 and the upper surface of the first flange 23 are fitted, and the third heat preservation cover 12 and the fourth heat preservation cover 13 are fixed by bolts to complete the installation and fixation of the second heating mechanism, and the resin in the discharge pipe 9 can be heated to prevent it from solidifying, which makes the flap 11 unable to rotate.

[0033] See also Figure 1-5 As a further implementation of the driving mechanism: the driving mechanism includes a first connecting plate 16, a second connecting plate 17 and a hydraulic cylinder 18, the first connecting plate 16 is connected to the support frame 1, one end of the second connecting plate 17 is connected to the rotating shaft 10, the hydraulic cylinder 18 is rotatably arranged at the bottom of the first connecting plate 16, and the telescopic end of the hydraulic cylinder 18 is rotatably connected to the second connecting plate 17.

[0034] Specifically, the two ends of the hydraulic cylinder 18 are rotatably connected to the first connecting plate 16 and the second connecting plate 17 respectively. When the hydraulic cylinder 18 is extended, the second connecting plate 17 is driven to rotate around the axis of the rotating shaft 10. Since the second connecting plate 17 and the rotating shaft 10 are fixedly connected, the rotating shaft 10 is driven to rotate together. When the rotating shaft 10 rotates, it drives the flap 11 to rotate together, thereby realizing the closing and opening of the discharge pipe 9.

[0035] In summary, when the overall equipment is in use:

[0036] The first heating plate 5 and the second heating plate 6 are respectively placed in the first heat-insulating cover 3 and the second heat-insulating cover 4, and the first heating plate 5 and the second heating plate 6 are electrically connected to an external power supply. The first heat-insulating cover 3 and the second heat-insulating cover 4 are sleeved outside the cone 7 and the discharge pipe 8, and the first heat-insulating cover 3 and the second heat-insulating cover 4 are fixed by bolts. The first heating plate 5 and the second heating plate 6 can heat the cone 7 and the discharge pipe 8 to prevent the internal resin from solidifying and affecting the discharge.

[0037] The third heating plate 14 and the fourth heating plate 15 are placed in the third heat-insulating cover 12 and the fourth heat-insulating cover 13 respectively, and the third heating plate 14 and the fourth heating plate 15 are electrically connected to an external power supply, the third heat-insulating cover 12 and the fourth heat-insulating cover 13 are sleeved outside the feed pipe 8 and the discharge pipe 9, and the through holes 21 on the third heat-insulating cover 12 and the fourth heat-insulating cover 13 are matched with the bearing 22 outside the rotating shaft 10, and the third limit plate 25 and the upper surface of the first flange 23 are fitted, and the third heat-insulating cover 12 and the fourth heat-insulating cover 13 are fixed by bolts to complete the installation and fixation of the second heating mechanism, and the resin in the discharge pipe 9 can be heated to prevent it from solidifying, which causes the flap 11 to be unable to rotate.

[0038] The two ends of the hydraulic cylinder 18 are rotatably connected to the first connecting plate 16 and the second connecting plate 17 respectively. When the hydraulic cylinder 18 is extended, the second connecting plate 17 is driven to rotate around the axis of the rotating shaft 10. Since the second connecting plate 17 is fixedly connected to the rotating shaft 10, the rotating shaft 10 is driven to rotate together. When the rotating shaft 10 rotates, it drives the flap 11 to rotate together. When the flap 11 rotates to a vertical state, the resin can be discharged normally. When the flap 11 rotates to a horizontal state, the two sides of the flap 11 are respectively fitted with the first limit plate 19 and the second limit plate 20, and the discharge pipe 9 is closed to prevent the resin from being discharged.
